<p>PURPOSE:To remarkably simplify the operational procedures for image processing and to reduce production cost of a machine by making an original platen and a coordinate input means common with each other. CONSTITUTION:The original platen 12 consists of a transparent material such as glass, acrylic, etc., that transmits oscillation, while an inputting pen 13 comprises an oscillator of such as a piezoelectric element in itself. An original 16 is placed with its front surface up on the platen 12, and an area to be copied is designated with the inputting pen 13. The oscillation of the pen 13 is inputted to the platen 12 through the original 16, and detected by oscillation sensor 31a-31c. An operational control circuit 36 obtains the straight distances between the respective sensors and oscillation inputting points from oscillation transmission time data outputted from a detection circuit 34, and thus obtained coordinate data are transmitted to a main control part via a register 36a and an input/output port 37. Thereafter, the original 16 is turned upside down on the platen 12, pressed with a pressing plate 11, and the copying is started.</p> |
