PURPOSE:To select a form slide with high accuracy and at a high speed, by putting plural form slides on a rotor and controlling the rotor after discriminating the form slide which is set at a prescribed position. CONSTITUTION:The information displayed on the screen of a display 11 by means of a processor 10 is recorded on a picture recording medium 14 via a half mirror 12 and a pickup lens 13. At the same time, a form slide 17 is selected out of a disk 26 and the picture of the slide 17 is superposed on the medium 14 via the mirror 12 and the lens 13. The slide set 17 at a prescribed position is discriminated among those on the disk 26. Then the output of this discrimination is compared with the output which designates the slide 17 to be set at the prescribed position. Based on the result of this comparison, a pulse motor which turns the disk 26 is controlled. |
