摘要： A paper feeding control system of an automatic paper feeder has a setting device for enabling a position to head a printing medium to be reset. The setting device consists of a read/write enable nonvolatile memory for holding a reset value of the heading position of the printing medium. Upon taking in and setting the printing medium, an operating panel switch is operated to correct the heading position of the printing medium. In addition, the corrected value is again written in the memory, whereby the heading position of the printing medium can be corrected and altered.

摘要： A printer comprises a first paper feed passage extending from the rear of a platen to a printing position through the lower part of the platen, and a second paper feed passage extending from substantially just under the printing position to the printing position. A first pinch roller is disposed on the way to the first paper feed passage for pressing a first paper against the platen. The first paper is fed by rotating the platen. A second pinch roller is disposed on the way to the second paper feed passage for pressing the second paper against the platen. Rotation of the platen here causes the second paper to be fed. In addition, a paper insertion device according to the present invention includes a flat part for placing a paper thereon and a slit for converting the advance direction of a paper from horizontal to vertical. With the second paper placed on the flat part and inserted into the printer, the paper is directed upward after the curved surface of the slit and allowed to enter the second paper feed passage with ease for further advance.

摘要： A printer includes a controller for providing a sequence control for the printer in its entirety in response to a control signal and a video signal from another controller. A printer head is adapted for latching and printing a printing data signal transmitted from the controller. Print data arithmetic and logic circuitry provides a logical operation processing for video data signals, counting video clock signals transmitted from the controller, and includes storage for storing the video data signals transmitted from the controller, a selector responsive to reference line timing signals for selectively alternately outputting the video data signals, an additional line signal generator for generating from video signals received from the controller, a video data signal representing an additional line destined for between reference lines during an interval of timing, and logical operation circuitry for performing a logical operation for the video data signals read out from the storage and supplying to the printer head the video data signals subjected to the logical operation in the form of the printing data signal.

摘要： An IC card connecting mechanism connects an IC card having a terminal array with a connector for connecting the IC card to external equipment. The IC card connecting mechanism includes a frame of the IC card, having a peripheral rim provided with recesses at opposite ends of the front portion thereof, a terminal protecting member of the IC card, having a terminal protecting part for protectively covering the terminal array, and legs extending from the opposite longitudinal sides of the terminal protecting part and held at respective free ends thereof on the frame of the IC card. A body of the connector has guide legs for guiding the IC card upon inserting the IC card in the connector. Lifting devices provided in the body of the connector enter the recesses of the frame to lift up the terminal protecting part of the terminal protecting member when the IC card is inserted in the connector. Thus, the terminal protecting part of the terminal protecting member is lifted up automatically to expose the terminal array for electrical connection with conductors of the connector when the IC card is inserted in the connector.

摘要： Disclosed is a serial printer comprising a carriage loaded with a printing head and moved in the horizontal direction, wherein a motor is contained in the carriage, a pinion is attached to a rotor shaft of the motor, a rack engaged with this pinion is attached onto a guide rail for movably supporting the carriage and the carriage loaded with the printing head is moved along the rack by rotating the pinion engaged with the rack by rotation of the motor.In this serial printer, the power loss of the motor due to the presence of an intermediate power transmitting member indispensable for the conventional printer, such as a wire rope, a toothed belt or a screw shaft, can be eliminated, and occurrence of troubles due to stretching or deformation of this intermediate power transmitting member is prevented. Accordingly, the capacity of moving and positioning the printing head is increased. Furthermore, since the carriage is of the self-running type, it is possible to adopt an embodiment in which at least two carriages are mounted on one printer and they are independently moved to effect the delivery operation. Accordingly, the printing speed can be increased and multi-color printing can be performed.

摘要： A wire driving mechanism for a wire-dot print head employs a piezoelectric element or a magnetostrictive element as a driver (5). To enable printing with a satisfactorily high print quality, the wire driving mechanism employs the extensional force of the driver (5) to pivot two generally parallel levers (3a, 3b) respectively having fixed ends. When the levers (3a, 3b) are pivoted, the free end of each of the levers (3a, 3b) is moved by a displacement which is a multiple of the extension of the driver (5). The respective displacements of the free ends of the levers (3a, 3b) are transmitted by a pair of support members (6a, 6b) to opposite sides of a driving member (8) at positions on different levels with respect to the longitudinal direction of the driving member (8). As a result, the driving member (8) is moved so that a print wire (7) attached to the driving member (8) is advanced in a printing direction.

摘要： A cleaning device includes a brush roller configured to contact an image bearer while rotating to remove toner adhering to an image bearer, a bias applying device configured to apply a bias to the brush roller, and control circuitry configured to causes the bias applying device to apply a first bias in a first period from when the brush roller is new to when a cumulative travel distance or a cumulative rotation time of the brush roller reaches a predetermined value, and to apply a second bias in a second period after the first period. The first bias sends a first current through the brush roller, and the second bias sends a second current through the brush roller. The absolute value of the first current is smaller than the absolute value of the second current.
