Printer ribbon switching mechanism

Abstract

Abstract PURPOSE:To obtain the titled mechanism, wherein color switching of multicolor ink ribbon is performed in synchronization with a detecting means which selects and detects one color of the multicolor ink ribbon, while the amount of displacement of an ink ribbon cassette can be made large, and life of the ribbon can be elongated. CONSTITUTION:When a cam 5 is rotated by the rotation of a motor 1, levers 7 on the sides of frames 16 and 17 are moved, and a sliding shaft 10 is slidden. The ribbon cassette 12 which is attached to the sliding shaft 10 is also moed up and down. When the lever 7 is lowered to the lower dead point, an optical reset detector 13 is turned ON so as to obtain a standby state. A detecting plate has four contact parts 31-34. When two detecting brushes 19 are contacted with the contact parts, a motor stopping signal is inputted, and the position of the ribbon is determined.
