Title: Controlling method for sheet feeding
Inventor: NAKAMURA TADASHI
IPC: B41J2/51
Filed: 1989-01-09
Abstract: PURPOSE:To prevent a sheet feeding pitch from varying due to its backlash and to obtain a desirable printing quality by absorbing the rotation of a preceding backlash of a gear transmission mechanism, and feeding a sheet. CONSTITUTION:A sheet feed roller 1 is so fed longer as to precede at a distance corresponding to a backlash by the backlash of a gear transmission mechanism for driving a sheet feed roller 1, but since the position of the sheet 5 at a predetermined sheet feeding pitch (a) at the time of passing the rear end of the sheet 5 is disposed at a position above the sheet feeding pitch (a), the backlash is absorbed until the sheet 5 is then fed to the printer of a thermal head 10 at the remainder of the predetermined sheet feeding pitch (a), and the sheet feeding pitch (a) is not varied. Accordingly, since the variation in the sheet feeding pitch due to the backlash of the gear of the gear transmission mechanism can be prevented, when a printing is performed by the thermal head 10, it can effectively prevent omission, superposition of prints, etc., thereby obtaining a desirable printing quality.
