Abstract: A display device and an image forming apparatus capable of reducing discomfort of a worker during maintenance work and improving the work efficiency, are provided. In a copier, an orientation of a display screen of a display device is detected and when the display screen changes its orientation, an image appearing on the display screen changes accordingly. It is determined how the copier is viewed from a worker, and then screen display is performed so that an image appearing on the display device looks the same as the copier which the worker directly sees.

Abstract: An invention allows a stepping motor to be reliably driven to rotate when initializing the driving and allows power consumption of the stepping motor to be reduced. The controller, when initializing the driving (for example, replacing a battery), controls a main drive pulse generator to drive a stepping motor using a main drive pulse having a maximum energy and sets the generation cycle of a pulse down control signal of a pulse down counter for pulsing down the main drive pulse to a first cycle to drive the stepping motor, and when pulsing down the main drive pulse to that having a predetermined energy, changes the generation cycle of the pulse down control signal of the pulse down counter to a second cycle.

Abstract: When a stepping motor is driven to rotate by a main driving pulse, if an induced signal exceeding a reference threshold voltage is detected only in a third segment, a pulse down operation is performed, and the main driving pulse is not changed when the same is detected in at least a first and the third segments. When it is detected only in a second and the third segments, a rank-up is performed without performing the driving by a correction drive pulse and, when it is not detected in at least the third segment, the rank up operation is performed after the driving by the correction driving pulse.

Abstract: A control unit is provided which drives a stepping motor in a first mode in which a driving pulse is selected between one kind of main driving pulse and a correction driving pulse with energy greater than the one kind of main driving pulse in accordance with a rotation state of the stepping motor and the stepping motor is driven or a second mode in which the driving pulse is selected among plural kinds of main driving pulses and a correction driving pulse with energy greater than the plural kinds of main driving pulses in accordance with the rotation state of the stepping motor and the stepping motor is driven. The control unit switches a mode between the first and second modes depending on whether the voltage of a secondary cell serving as a power supply exceeds a switch voltage and drives the stepping motor.

Abstract: A secondary cell supplies drive power to a motor of an analogue electronic timepiece, and a state detection circuit detects whether or not a state at the time of driving the motor is a predetermined state. A cell voltage detection circuit detects a voltage of the secondary cell at intervals corresponding to a detection result by the state detection circuit. A control unit drives the motor by selecting a drive pulse of energy corresponding to a detection result of the cell voltage detection circuit out of drive pulses of different energies. When the state detection circuit detects that a state at the time of driving the motor is the predetermined state, the cell voltage detection circuit detects the voltage of the secondary cell at intervals shorter than intervals when the state detection circuit detects that the state at the time of driving the motors is not the predetermined state.

Abstract: The present invention aims to prevent a main drive pulse from being moved to a rank having a potential to cause a non-rotating state. A detection segment for detecting a rotating state of a stepping motor is divided into a first segment immediately after the drive with a main drive pulse, a second segment, and a third segment and, when the stepping motor is rotated by the main drive pulse, the main drive pulse is not changed when a detection signal exceeding a reference threshold voltage is detected at least in the first and second segments. When it is detected only in the first and third segments, or detected only in the third segment, the rank is moved upward and, when it is not detected in any segment, or detected only in the first segment, the rank is moved upward after the drive with a corrective drive pulse. When it is detected only in the second segment or detected only in the second and third segments, the rank is moved downward.

Abstract: A voltage detection circuit detects a voltage of a secondary cell that powers a stepping motor. A rotation detection circuit detects a rotation state of the stepping motor, and a control unit selects a main driving pulse for driving the stepping motor based on the detected rotation state from plural kinds of driving pulses having different energies. An analog display unit announces that the voltage of the secondary cell becomes a predetermined reference voltage when the voltage detection circuit detects that the voltage of the secondary cell becomes the predetermined reference voltage. When the control unit selects a predetermined main driving pulse before the voltage detection circuit detects that the voltage of the secondary cell becomes a current reference voltage, the control unit sets the reference voltage to the predetermined reference voltage higher than the current reference voltage.

Abstract: A power generation unit generates electric power depending on light to be irradiated to a light receiving surface. An electricity storage unit stores the electric power generated by the power generation unit and outputs the stored electric power. A voltage detection unit detects a voltage of the electric power that is output from the electricity storage unit. A processing unit performs time measurement. A chronograph indicator points a time counted by the processing unit and is fixed by a mechanism while the time measurement is stopped. A second driving circuit drives the chronograph indicator by the use of the electric power that is output from the electricity storage unit. The processing unit drives the second driving circuit when the voltage of the electric power which is output from the electricity storage unit is equal to or greater than a predetermined threshold value.

Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the battery reliability service life time from being exceeded even when the period of time that the chronograph function is used is short, making it possible to prevent failure generation in the chronograph timepiece due to liquid leakage. A 24-hour counter down-counts a period of time that has elapsed starting from 24 hours, and a chronograph counter down-counts the period of time that chronograph measurement operation is performed from a predetermined time; when the count values of the 24-hour counter and the chronograph counter become equal to each other, a processing unit consumes a battery for the residual period of time of the two counters by a battery power consuming unit.

The image forming apparatus having a copy function includes an identification information extracting portion for extracting identification information (page number and heading information) which identifies originals from image data of read originals, a selecting portion for displaying the extracted identification information and accepting the identification information selected by the user as a target for image formation, and an output portion for printing image data excluding the identification information from the image data of the target for image formation accepted by the selecting portion. Here, the identification information is preferably formed with code information.

Abstract: A motor drive device includes a charging detection and reverse current prevention portion and a pulse selection control portion. The charging detection and reverse current prevention portion detects a charging state of a secondary battery that is charged by an electromotive force of a solar battery, the charging state indicating whether the secondary battery is being charged. The pulse selection control portion causes a first drive pulse for driving a motor to be generated and, in a case where the charging state that is detected by the charging detection and reverse current prevention portion is different after the first drive pulse has been output from what it was before the first drive pulse was output, causes a second drive pulse for driving the motor to be generated.

Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent the chronograph drive timing and the magnetic field detection timing from overlapping each other to unnecessarily effect driving with correction drive pulses. A processing unit controls drive circuits so as to drive a time indication motor and a chronograph indication motor with a predetermined timing based respectively on timekeeping information obtained and chronograph measurement information obtained, and effects control such that a magnetic field detecting unit detects a magnetic field with a predetermined timing; when the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit overlap each other, the processing unit changes the magnetic field detection timing for the magnetic field detecting unit so that the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit may not overlap each other.

Abstract: When it is judged that a chronograph second counter and a chronograph minute counter have measured a maximum measurement time, a maximum measurement control unit controls a drive pulse generation circuit so as to drive and stop a motor such that chronograph hand stops at predetermined positions. When, in this state, a restarting operation is performed on a start/stop button, a normal chronograph measurement operation is restarted. At this time, a mechanical structure has been restored to a reset state, so that even at the time of restarting after the measurement of the maximum measurement time, the load at the starting operation is the same as that of the normal operation, thus generating no sense of incongruity.

Abstract: A stepping motor for driving time hands, a stepping motor for driving a calendar, and a stepping motor for driving chronograph hands are all housed in a bottom plate of a movement of an analogue electronic timepiece. The stepping motor for driving chronograph hands is connected to a battery can via a battery pressing piece. The stepping motor for driving chronograph hands is arranged such that a larger amount of external magnetic field passes that stepping motor than the other stepping motors via the battery can and the battery pressing piece. The rotational drive of the stepping motor for driving chronograph hands can be made stable even under the presence of the external magnetic field by setting a drive force of the stepping motor for driving chronograph hands larger than the drive forces of the other stepping motors.

Abstract: Disclosed is a chronograph timepiece in which it is possible to prevent a non-rotation state at the time of first driving when chronograph measuring operation is reset during motor drive and restarting is effected. When a resetting operation is performed on a reset button during the driving of a motor and a rotation detection circuit detects non-rotation, a drive control unit controls a drive pulse generation circuit such that the control is completed without reversing the polarity of a motor drive pulse output from the drive pulse generation circuit, and that the motor is driven by a drive pulse of the same polarity as that at the time of the previous resetting in response to a starting operation performed on a start/stop button, driving the motor by the drive pulse of the same polarity at the time of restarting after the resetting.
