TPH PRESSING DEVICE IN VIDEO COLOR PRINTER

摘要

The apparatus aligns the TPH (thermal printer head) on a photographic paper by a regular pressure in order to print regular density images. The apparatus comprises a lever, rotatably fixed and connected to the TPH (1) facing against a drum (19); a head alignment means (6) connected to a cam gear (8) driven by a head motor (11); a pressure control means regulating the alignment pressure on the TPH (1) when rotating the cam gear (8); a pressure transfer means transmitting the alignment pressure to a photographic paper (20) and a drum (19).
