Claims

[Claims for Utility Model Registration] A light source capable of emitting a light beam is provided within the device body, and the device is configured to guide the light beam emitted from the light source to the outside based on a drive instruction from a light source drive mechanism. In a thermal copying device comprising a light-transmitting part provided in a portion of the main body facing the light source, for setting an irradiation area of light rays emitted from the light source to the light-transmitting part between the light source and the light-transmitting part. To,
An irradiation area setting function comprising: a movably arranged light shielding plate; and a light shielding plate positioning mechanism provided on the apparatus main body to variably set the irradiation area by moving the light shielding plate. Thermosensitive copying device.
