<p>PURPOSE:To improve the operability by providing a transparent coordinate input tablet on an indicator, and designating a desired editing area of a displayed microfilm image by said tablet. CONSTITUTION:In a control system of a microfilm processor, as for an input/ output device 64, a transparent digitizer tablet of an ultrasonic wave system is superposed and placed on an indicator 65 constituted of a CRT display, etc., and through this tablet, a display image of the indicator 65 is observed visually. Also, the tablet concerned is constituted of a vibration transfer plate 8, and a position coordinate inputted with a vibration pen 3 is detected by a vibration sensor 6 of a corner part. Moreover, by executing a dot display at a position on the indicator 65 traced with the vibration pen 3, it is also possible to synthesize and display an image inputted from the digitizer tablet to a microfilm image. In such a way, other editing area than a rectangle can be designated.</p> |
