<p>PURPOSE:To prevent the imperfectness of an image or the margin in the case of using an undefined format recording paper from occurring, to accurately form an image, to make specifications for domestics and foreign use common and to improve economicity by counting picture element clocks according to a command quantity based on an output from a variable resistor which interlocks with an original guide and outputting a writing position signal for a recording paper at the time of finishing counting. CONSTITUTION:The variable resistor 211 slides by interlocking with an original guide 107, and an A/D converter 209 converts the analog output from the resistor 211 into a specified digital quantity. A ROM 202 stores a program for processing the control of each part of the device, a CPU 201 executes various kinds of processing in accordance with the program stored in the ROM 202, and a RAM 203 records the processed result of the CPU 201 and data, etc. A timer 210 counts the picture element clocks according to the command quantity from the CPU 201 by making a synchronism detection signal a trigger and outputs a counting finishing signal as the writing position signal. Thus, the imperfectness of the image or the occurrence of the margin in the case of using the undefined recording paper is prevented, the image is accurately formed, the specifications for domestics and foreign use are made common and the economicity is improved.</p> |
