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： An image-forming apparatus includes a developing roller and a developing blade. The developing blade applies toner to the developing roller to form a thin layer of toner on the developing roller. The image-forming apparatus performs a printing operation that includes a paper-feeding period and a developing period following the paper-feeding period. The developing roller rotates relative to the developing blade at a first speed during the paper-feeding period and then at a lower second speed than during the developing period, thereby eliminating chance of white lines of occurring in a printed image. The developing roller may be rotated at a constant speed in each printing operation until the circumferential surface of the developing roller has traveled over a certain cumulative distance. When the surface has traveled over the first distance, the developing roller may be rotated at an increased speed over a certain distance.

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 drive current for driving actuators is generated based on a first digital signal comprising n-bit binary data which is supplied from a microprocessor and it is applied to an excitation coil. The drive current is supplied to the exciting coil and is converted into a voltage which is then converted into a second digital signal comprising n-bit binary data. The binary data of the second digital signal is compared with the digital data of the first digital signal to detect an alarm condition. Furthermore, the second digital signal is compared with first and second reference value to set plural alarm conditions.

摘要： A method of controlling a cut-sheet feeder installed on a printer to feed a cut sheet from a sheet hopper (1) included in the cut-sheet feeder to the printing unit of the printer at a sheet feeding speed corresponding to that of the printer. The printer gives a correction signal (S.sub.1) of a predetermined pulse width to the cut-sheet feeder, and then the cut-sheet feeder converts the pulse width of the correction signal into a corresponding number of pulses of a clock signal generated by its control unit (25), and obtains the difference between the number of pulses of the clock signal and a predetermined reference value to determine the deviation of the frequency of the clock signal from a reference frequency. The difference between the number of pulses of the clock signal and the reference value is added to a reference motor controlling value for driving a stepping motor (4) at a reference speed to obtain a corrected motor controlling value. When the printer gives a sheet feed command signal (S.sub.f) to the cut-sheet feeder, the stepping motor is driven for rotation according to the corrected motor controlling value.

摘要： The operation of an automatic sheet feeder provided with a plurality of sheet hoppers which are used selectively to feed sheets to a printer is controlled. A control unit of the printer supplies a multiplex control signal including a hopper select signal and a sheet delivery signal to the automatic sheet feeder through a single signal line. The width of pulses of the hopper select signal is smaller than a predetermined time, while the width of the sheet delivery signal is greater than the predetermiend time. The pulses of the multiplex control signal are compared with the predetermined time to discriminate the hopper select signal and the sheet delivery signal from each other. That sheet hopper corresponding to the number of pulses of the hopper select signal is selected, and then the automatic feeding of sheets from the selected sheet hopper commences upon the reception of the sheet delivery signal.

摘要： A drive system for a wire dot head is provided with sensors for detecting displacements of corresponding print wires. Each sensor outputs a movement initiation timing signal and an impact timing signal for the corresponding print wire. An electric current to be fed to an associated coil is normally controlled by these timing signals. It is detected whether these timing signals are obtained in a predetermined time period. If not, electric power is continuously fed to the coil or is forcedly cut off so that the timing signals are obtained within the predetermine time period.
