摘要： A pulse motor control apparatus for a polyphase excitation type pulse motor variably and independently controls excitation currents supplied to excitation coils. Ratios of any excitation current to other excitation currents supplied to the excitation coils are changed stepwise to rotate a composite magnetic field vector forward by those excitation coils each multiple of a real number of a predetermined unit angle at one time for controlling the rotational angle of a rotor of the pulse vector. The pulse motor control apparatus assures fine control for the rotational angle of the rotor compared with prior cases where currents supplied to a plurality of excitation coils are switched on and off for rotational control. Application of the present control apparatus to printers, etc., precludes replacement of gears, etc., due to types of print heads mounted thereon. Additional advantages such as inprovement of a torque ripple upon driving the pulse motor assure extensive application to various fields.

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 process for forming a light-reflecting bar code on an end disc of photographic film spool is performed by the steps of placing on the end disc of photographic film spool a hot-stamp film comprising, in order, an adhesive layer, a light-reflecting metal layer, a transparent protective layer, a releasing layer, a support film, and a stain-shielding layer formed of material inhibiting migration of a compound having a low molecular weight from the support film (e.g., compound having a siloxane bonding or deposited inorganic oxide) in such manner that the adhesive layer is brought into contact with the end disc, and pressing for 0.1 to 2.0 seconds a stamper having a heated bar code-stamping die, so as to transfer the light-reflecting metal layer onto the end disc in the form of the bar code.

摘要： A color image recording apparatus operates in a color print mode and in a monochrome printing mode. A set of color print heads are driven in accordance with corresponding color image data. A monochrome print head is driven in accordance with black image data. A controller transmits in parallel or in serial the color image data and the black image data to the corresponding print heads in a color printing mode. The controller transmits the black image data faster in the monochrome printing mode than in the color printing mode, thereby increasing printing speed. The controller may include signal processing circuits such as compressing circuits and expanding circuit for the respective color image data and black image data. In the monochrome printing mode, the controller divides the black image data into a plurality of segments and supplies the segments in parallel to the signal processing circuits. The signal processing circuits process the segments and supply the processed data to the monochrome print head in a predetermined sequence, thereby increasing printing speed.

摘要： An image recording apparatus includes a print engine that transfers a toner image on a recording medium, and a medium sensor disposed at an entrance of the print engine. The medium sensor outputs a detection signal when a recording medium passes by the medium sensor. When a following one of two consecutive pages of the recording medium is jammed at an entrance of the print engine, a controller completes a printing operation of a preceding one of two consecutive pages and indicates the jam of the following one of the two consecutive pages. Alternatively, the controller may control the fixing unit to a predetermined temperature, subsequently allowing the recording medium to pass through the fixing unit at a first speed and to be discharged. Still alternatively, the controller causes the print engine to stop and subsequently discharges the recording medium.
