Abstract: A camera cradle apparatus includes an extension connector which connects a camera including a power supply button, a connector which connects an external terminal through a network so as to allow communication, and a control unit which controls a connection state of the connector. At least one of the external terminal and the camera cradle apparatus includes an external power supply button which performs on-off operation of the power supply of the camera. The control unit controls the connection state of the connector in accordance with whether the power supply of the camera is turned on by either the power supply button or the external power supply button.

Abstract: Provided is a system including a computer, a display device for performing display based on a signal from the computer, and an access point for performing communication between a wired network and a wireless network and disposed between the computer and the display device. In response to operation for turning ON the display device or to a power ON instruction from another client device, the access point is activated and sends an activation signal for activating the computer. Upon receiving the activation signal, the computer is activated and outputs a signal to the display device. Further, in response to operation for turning OFF the display device or to a power OFF instruction from another client device, the access point sends a power shutoff signal to the computer and shuts off its own power. Upon detecting the power shutoff signal, the computer performs a shutdown process. When the signal from the computer stops being received, the display device shuts off its own power.

Abstract: Since cable external equipment has the advantage over radio external equipment, data is transferred through a cable when active cable external equipment exists, and data is automatically transferred to radio external equipment when active cable external equipment does not exist.

Abstract: An ink jet recording apparatus comprises input keys for inputting information to be recorded, a protection device for protecting a recording head for discharging ink to record onto a recording medium in accordance with the input keys, and an execution controller for carrying out the protection of the recording head with the protection device by deciding whether a predetermined period has passed, after input by the input keys.

Abstract: In a printer which selects a character by moving a type wheel by a stepping motor, phases other than a stable phase of windings of the stepping motor are shorted when a rotor of the stepping motor comes to a vicinity of a stable point of a target phase, and an exciting time of the stable phase is gradually extended. The primary drive signal is turned off during energization of a retaining signal and during hammer energization.

Abstract: A control device for driving a stepping motor having a plurality of coils is provided with timing control means for inserting a quiescent time into a phase signal for actuating energization of the coils.

Abstract: A printer has a mechanism for erasing a printed character by impacting a type through an erasing ribbon, and a stepping motor for rotating a type wheel to select a character. In an erasing operation, the type wheel is rotated by the stepping motor by a small rotation angle so that the type is superpositioned on the printed character.

Abstract: In a driving circuit for a stepping motor in which a phase current corresponding to a predetermined reference voltage is generated when an excitation signal for each phase of the stepping motor is being produced and a coil of the corresponding phase is excited by the phase current, the supply time of the phase current is controlled by the pulse signal of a pulse generator for varying the pulse width, thereby improving the rising state of the phase current.

Abstract: A control system for a stepping motor comprises flowing an electric current to a plurality of phases in succession and driving the stepping motor, and flowing a loop current to a coil of the phase which is not concerned in the driving of the stepping motor when the deceleration area of the stepping motor is reached, thereby obtaining a braking force.
