Title: Thermal color transfer recorder
Inventor: KAWAKAMI KAZUHISA
IPC: B41J35/16
Filed: 1986-06-03
Abstract: PURPOSE:To obtain a thermal color transfer recorder which is of simple structure and can easily be handled by operating a sensor itself synchronized to the actions of an ink film, ink film case and a thermal frame head. CONSTITUTION:A sensor 3 is mounted on a sensor holder 4 and is so designed as to rotate around a holder rotational shaft 5. This mechanism enables the sensor 3 to select a sensing position and other two positions, and sets the sensor near film during sensing operation and sets it remotely from the film when the latter is loaded/unloaded. When a head 9 and a head frame 10 rotate in an arrow direction A, a lever 11 is pushed down, thereby a holder hook 7 receives a force, rotating the sensor holder 4 in an arrow direction B and separating the sensor from the film. Thus the sensor is surely moved when the ink film is loaded/unloaded, preventing the former from contacting the latter.
