Abstract: PURPOSE:To inhibit overvoltage in the forward direction while miniaturizing a clamping circuit and improving efficiency by forming the clamping circuit clamping the voltage of the capacitor of a snapper circuit within predetermined value so as to be directed to the forward direction to an SCR. CONSTITUTION:Clamping diodes 51, 52 are connected in polarity which discharges charging voltage, which is directed toward the forward direction to the gate-turnoff thyristor GTO of the capacitors 36 from the series nodes of the diodes 35 and capacitors 36 of the snapper circuit, toward a power supply 1. Clamping diode currents are decelerated in a short time by setting the sum of the forward voltage drops of the diodes 51, 52 and snapper diodes 351, 352 to value larger than the forward voltage drop of a free wheel diode 4. Accordingly, the forward direction voltage of the GTO can be inhibited, and the GTO device can be miniaturized and efficiency is improved.

Abstract: PURPOSE:To simplify data processing after the input of a picture by arranging an annular illumination means on a horizontal plane around an object to be recognized and also arranging an illumination means on the upper position of the object to image pick up said object by the illumination. CONSTITUTION:The illumination apparatuses 3-1-3-3 and 4-1-4-3 are lights for picture input in the X and Y directions of a rectangular parallelepiped object respectively. These illumination apparatuses are arranged annularly. A picture is inputted by using an ITV camera 2.

Abstract: PROBLEM TO BE SOLVED: To prevent the undesirable work of a film transfer device, after the sealing part of a film cassette is closed by fixing the film transfer device, when the sealing part of the film cassette is in a closing position. SOLUTION: Locking for the film transfer device is controlled by a controller, by a method capable of cutting off the film transfer device from another operation or fixing the film transfer device, when the tail of a film 26 is completely pulled into the film cassette 25 which is inserted in a camera and the sealing part 33 is moved to the closing position. The controller makes the transfer of the film possible. The controller can perform the transfer very easily at least up to a transfer state where the passing through the aperture of the camera, of the tail of the film 26 is completed. Then, the sealing part 33 is not stopped with respect to the film 26, before this transfer state, so that the scratching of the film is reliably prevented. Therefore, the undesirable friction between the film 26 and the sealing part 33 can be prevented.
