    Abstract: A driving circuit for a stepping motor comprises bridge circuits being composed of switching elements connected between a DC power source and the coils of a stepping motor, rectifier diodes connected in antiparallel to the switching elements, capacitors connected in parallel to the bridge circuits, and constant voltage diodes connected between the DC power source and junction points of the bridge circuits and the capacitors. The switching elements are constituted to be ON/OFF controlled by a predetermined exciting system, and the constant voltage diodes are set to turn conductive to form a feedback circuit even if they are in a biased state in the reverse direction when the capacitors are charged up to a voltage which is higher than the source voltage and lower than the breakdown voltage of the switching elements by the counter electromotive force induced in the coils.

    Abstract: The present invention relates to a method for setting a desired color in a thermal transfer printer using a color ink ribbon which has ink sections of plural colors arranged in continuous repeating units in the longitudinal direction of the ink ribbon. Taking note of the fact that in a short distance from a color detecting sensor up to a printing position, the amount of the ribbon wound up for a rotational amount corresponding to one step of a ribbon winding motor is almost constant, irrespective of the amount of the ink ribbon used, the present invention was accomplished. According to the present invention, the number of steps of the motor for feeding a color distinguishing marker on the ink ribbon is counted by a sensor and the ribbon is fed from the position of the said sensor up to the printing position by a predetermined integer multiple of steps of the counted value, whereby a desired color is set in the printer accurately.

    Abstract: A reading apparatus and a recording apparatus having the reading apparatus which can reduce storage capacity for storing read data and, because the read data processing modes can be switched according to the type of documents to be processed, perform fast and proper document reading operation. If a document to be processed is an image document, the controller operates in the image processing mode in which M pieces of read data are sampled out of N pieces of read data and a mean value of the M pieces of read data is calculated to be stored in the memory as gradation data of one pixel. If the document is a text document, the controller operates in the text processing mode in which read data of one read unit of the image scanner is digitized by a threshold to be stored in the memory. Switching between these two processing modes is performed by the conversion processing operator section in the controller.
