PURPOSE:To easily attach and detach an electrode contact to and from an external circuit, and to effectively utilize it in a conventional device, by providing the electrode contact for short-circuiting electrodes of a detecting plate, on a cassette for the detecting plate. CONSTITUTION:A detecting plate 7 on which an electrostatic latent image is formed is contained in a cassette housing 21 made of bakelite, and is provided with a cover 22 having a hinge 23. A transparent electrode 1 of the plate 7 is connected to an electrode contact 25 in its extended part 27, and an electrode 6a is connected to an electrode contact 24 by a ribbon 26. In this way, by providing both the contacts 24, 25, the electrode contact is attached and detached easily to/from an external circuit, and prescribed electric connection to the other device is executed. In case of X-ray exposure, both electrodes are short-circuited, and when taking them out, they are made off. Therefore, this cassette can be installed easily to an X-ray photographic base using a film cassette, and it can be utilized effectively in a conventional device. |
