PURPOSE:To enter symbols, etc., in a phtosensitive material in easy-to-see states without damage, by fitting an optical core, having a hole guiding light to the inside, to an optical core holder, and by connecting it to a flashlight. CONSTITUTION:An optical core 1 having a hole guiding light to the inside is fitted to an optical core holder 2. The optical core holder 2 moves forth and back, being supported by a sheath 3, corresponding to the pushing force of an elastic body 4 and pressure applied to the optical core 1. the rear end part of the optical core holder 2 is connected to an automatic switch 5, which is turned on and off by the forward and backward movements of the optical core holder 2. The sheath 3 has a fitting part 6 which makes an electric connection between the automatic switch 5 and the sheath 8 of the flashlight. In this constitution, when the optical core is pressed against a photosensitive material, the automatic switch is pushed to turn on the flashlight, and consequently symbols, etc., are entered in the phtosensitive material in easy-to-see states without any damage. |
