Title: Printer
Inventor: FUJIWARA ICHIJI
IPC: B41J3/36
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To provide a printer to be stored in a device bay of a lap top device by having a smaller platen roller diameter. SOLUTION: A paper guide 20 having the same shape as the outer circumferential shape of a platen roller 2 is pressed against the platen roller 2 by a spring 25 by an appropriate pressure. Since a heat sensitive paper 1 is interposed between the paper guide 20 and the platen roller 2, a sufficient contact area can be ensured so that the diameter of the platen roller 2 can be provided smaller. Furthermore, since the heat sensitive paper 1 is guided along the periphery of the platen roller 2 by the paper guide 20, the risk of paper jamming generation can be eliminated, and thus a high reliability can be achieved. Therefore, a thin and highly reliable printer can be provided even in the case it has the paper feeding direction changed by 180 degrees along the platen roller for realizing the front-in and front-out so as to be stored in a device bay.
