CONSTITUTION:The first ribbon guide 5 has proper pressing force to a shuttle head 2 and functions as a recording jump stand having an inlined part 5a and not hooking the end surface of an ink ribbon 4 with respect to the recording paper 7 inserted in a recording transfer direction 7A. The second ribbon guide 6 functions a recording paper jump stand having an inclined part 6a and not hooking the end surface of the ink ribbon 4 with respect to the recording paper 7 inserted in a recording paper transfer direction 7B.

摘要： PURPOSE:To obtain a cartridge mounting and detaching mechanism replaceable without contaminating the hand by mounting a pair of ribbon guides provided on both sides at the leading end of a printing head, a gear train for moving said guides in vertical direction, and a drive motor. CONSTITUTION:An ink ribbon cartridge mounting and detaching mechanism has a pair of ribbon guides 1, 1 freely movable in vertical direction and provided on both sides at the leading end of a printing head, gears 2, 3 for moving the ribbon guides 1, 1 in the vertical direction, and a drive motor 9 connected drivably to the gears 2, 3, and the pair of ribbon guides 1, 1 are raised by the drive motor 9 through the gears 2, 3 on the basis of a replacement command of an ink ribbon cartridge 7 fed from an operating panel and an ink ribbon 8 is mounted on the ribbon guides 1, 1 under this state. By again issuing a setting completion command of the ink ribbon cartridge 7 from the operating panel, the ribbon guides 1, 1 are allowed to fall and to be mounted at a predetermined position. Therefore, the ink ribbon cartridge can be easily set within a short time without touching said cartridge with the hand.
