The platen is placed in the rear end portion of the printer frame. An opening for insertion of printing paper is formed in the rear end surface of the frame to which the platen is approximated. A feeder for feeding continuous printing paper is provided for connection to this opening. The feeder includes a pair of laterally adjustable feed guide blocks each having a sprocket wheel. These blocks are essentially hollow and have interior reinforcing plates and an open bottom.

Abstract: A printer for printing characters through a printing ribbon on printing paper placed on a platen by moving a carriage along the platen and driving a printing head on the carriage. The platen is placed in the rear end portion of the printer frame. An opening for insertion of printing paper is formed in the rear end surface of the frame to which the platen is approximated. Various paper feeders for automatically supplying single sheets or a continuous printing paper are connected to the rear of the printer frame so as to face the open area. A feed roller is moved against the platen when a paper feeder is installed.

Abstract: An imaging apparatus for use in an electronic endoscope or the like is provided with a mechanically driven light-shielding plate, wherein imaging is effected by using a solid-state imaging device starting from a time when an amount of light shielded by this light-shielding plate becomes minimal, or imaging is effected repeatedly during a short exposure time within a transient period during which the amount of light shielded becomes minimal, and when an signal level of each image reaches a reference level, that signal is stored in a memory.

Abstract: This invention relates to an ultrasonic endoscope which includes a manipulating portion coupled to a light source device and an ultrasonic observation apparatus through a universal cord, an insertion portion inserted in a body cavity, and a sub-manipulating portion arranged between the insertion portion and the manipulating portion, an air-supply path and a suction path being arranged in the universal cord, the insertion portion having a distal end portion on which an observation optical system and an ultrasonic vibrator are mounted, the ultrasonic vibrator being covered with a balloon fixed to a surrounding portion of the distal end portion, and an optical system water-supply pipe for supplying water for washing the observation optical system and a balloon water-injection pipe for injecting water into the balloon being arranged in the insertion portion.

Abstract: An ultrasonic diagnostic apparatus includes an operation section and an insertion section adapted to be inserted into the body cavity of a human being. The insertion section has an insertion channel extending therethrough. A guide sheath is slidably inserted into the channel and has a distal end portion pivotally supported on the distal end of the insertion section by link arms. An ultrasonic probe is fixed to the distal end of the insertion section. An image guide extends through the sheath to the end face thereof. A guide channel for guiding a puncture needle extends through the sheath and opens at the end face thereof. When being pushed out from the insertion section the distal end portion of the sheath is pivotted to change its direction.

Abstract: An ultrasonic endoscope according to the present invention comprises an insertion portion having a hard distal end portion. A first holding member is provided to the hard distal end portion, and an ultrasonic vibrator is mounted on the first holding member. A second holding member, detachably mounted with respect to the first holding member, is provided at the hard distal end portion, and an observation optical system is mounted on the second holding member. The second holding member is fixed to the first holding member by a fixing means. In the ultrasonic endoscope with the above arrangement, the first holder for holding the ultrasonic vibrator can be separated from the second holder for holding the observation optical system.

Abstract: A motor driving device in a printer wherein a selection signal for carrying out the driving selection of the respective stepping motors in outputted from a control circuit to the stepping motor for an automatic paper feeding mechanism of forms which comprises one of two driven sections and an other stepping motor for a form feeding mechanism which comprises the other driving section in a printer to select one of these motors through drive selection elements corresponding to respective stepping motors, and in which a phase control signal is successively sent to phase current flowing elements provided commonly in the same phase coils or both stepping motors, respectively, and the switching operation of the phase coils of the selected stepping motor is carried out to rotate and drive said motor, and the rotation position of said motor is always recognized by memorizing the corresponding data of each output of said phase control signal, and after the other motor has been selectively driven, in selecting said one

Abstract: A printing mechanism assembly, including a platen, a carriage bearing a print head thereon, a ribbon cassette, and drive mechanisms for driving these members for printing operation, is mounted on a subframe to form a unit. Also, control means including a printed board for controlling the operations of the drive mechanisms, and power supply means for supplying electric power to the drive mechanisms through the control means are unitized independently. All of the resulting units are mounted on a main frame. The subframe, with the printing mechanism assembly thereon, is removably mounted on the rear half portion of the main frame; the control unit on the underside of the main frame, and the power supply unit in a notch formed at the front corner portion of the main frame. Power supply units of various specifications may be used alternatively which incorporate different transformers adapted for varied external supply voltage connected thereto.

Abstract: A printing mechanism assembly, which includes a platen, a print head opposed to the platen for printing operation, a carriage carrying the print head thereon, and a guide rod for supporting the carriage so as to be movable along a print line, is supported on a plastic subframe. The subframe is provided integrally with channel-shaped reinforcing members extending parallel to the platen at front and rear end portions of the subframe. Each reinforcing member is formed integrally with a number of reinforcing ribs arranged at regular intervals in the longitudinal direction of the member. The subframe is mounted, at its front and rear end portions, on a main frame. For the mounting arrangement, engaging projections are formed on the rear end portion so that they can substantially horizontally engage mounting recesses in the main frame with the aid of vibration-proof rubber members.

Abstract: In order to control shifting of the transmission of a vehicle, from the viewpoint of obtaining the optimum fuel economy and/or power output performance, a transmission shift control device is proposed which comprises a throttle sensor which generates a throttle signal, an engine speed sensor which generates an engine speed signal, a shift position sensor which generates a shift position signal indicating the present operating gear of the transmission, a memory which stores a relationship between the throttle opening and the engine speed for each shift position or operating gear of the transmission to give a target value for one of these two signals in accordance with the other of them, and a comparator which receives one of the above two signals and compares it with the target value therefor given from the memory and generates either an upshift signal or a downshift signal which is indicated to the driver or sent to the transmission so as automatically to shift it.

Abstract: For generating a transmission shift control command in accordance with the operating conditions of a vehicle engine, from the point of view of improving fuel economy of the engine, a transmission shift control device has a throttle sensor which detects the throttle opening to produce a throttle signal, an engine speed sensor which detects the engine speed to produce an engine speed signal, a throttle comparator which compares the throttle signal with a reference signal, an engine speed comparator which compares the engine speed signal with a reference signal, and a switching circuit which generates an upshift command or a downshift command on the basis of signals from these comparators, these commands being sent to the transmission of the vehicle, or to a display visible to the driver.
