Abstract: PURPOSE:To reduce the troublesome operation of the operator by moving a page head causing paper clogging when paper clogging of a recorder is detected so as to reproduce automatically a picture lost by the paper clogging after the processing against paper clogging. CONSTITUTION:Paper detecting sensors 100, 101 detect the presence of paper in paper feeding cassette and count the number of paper sheets. Jam detection sensors 102, 103 detect the paper clogging in the equipment and count number of discharged paper sheets. If jamming takes place, the display of jamming is attained so as to confirm the presence of a retransmission request signal of picture information from a printer. When jamming takes place, the printer counts number of jammed paper sheets, outputs the number of retransmitted sheets to a disk equipment and inputs the number of sheets as a retransmission request sheet number (r). When the (r) is inputted, the content of a memory P is rewritten so as to allow the head to access the position restored by r-page. When the content of the memory P is smaller than a value (l), it means that the picture of one preceding part is lost and it is corrected. Then the access of the page from the P is started.

Filed: 1990-04-09
Abstract: PURPOSE:To decide the adaptability between both driver identification signals by applying a driver identification signal into a servo driver to show the type of this driver and at the same time reading another driver identification signal out of a controller via an interface set to the controller. CONSTITUTION:A servo driver receives the commands from a controller 11 via the command signals 5a - 5f and sends the position and the operating state of a motor back to the controller 11 in the form of the state signals 6a - 6f. The signals 5a - 5f include a servo ON signal (motor drive start signal), the control signal for an alarm resetting operation, etc., and the operation value signals like a speed command signal, etc. The signals 6a - 6f include the signals showing an alarm generating state and an operating state as well as the signals showing the position, the speed and the working state of a motor. In such constitution, the controller 11 reads the identification signal of the servo driver and can recognize it. Thus the combination error of both drivers 1 and 4 can be detected before the start of their operations.
