ようにしたものが存する。Conventional technology Conventionally, a support body for holding a cassette case in which a ribbon is stored is provided so as to be movable up and down, and wires are fixed to both sides of a ribbon guide that holds the ribbon in a slidable manner facing the printing section. Attach both ends of the wire to both sides of the support,
The support is rotated around a fulcrum using a motor, electromagnet, etc. as a drive source, and a ribbon guide is linked to the vertical movement of the support to switch ribbons, thereby performing multicolor printing. Exists.
発明が解決しようとする問題点
しかし、支持体を頻繁に高速で上下動作させると、ワイ

に混色が発生する。Problems to be Solved by the Invention However, if the support is frequently moved up and down at high speed, the ribbon guide suspended by the wire will vibrate, and the operation will not stabilize until the vibrations subside. On the other hand, the ribbon for multicolor printing is 4
Some products are coded into more than one color zone, and when printing in multiple colors, printing is performed using one selected zone, or multiple zones are overlapped on the same printing line, so it is necessary to move the ribbon to an accurate position at high speed. It is necessary to move it with
The switching frequency is also extremely high. Furthermore, there is a desire to make the printing width of each zone as narrow as possible, and the margin for the printing width of each zone is extremely small. Therefore, if there is even a slight deviation in the shift amount of the ribbon, color mixture will occur above and below the printed characters.
この発明はこのような点に鑑みなされたもので。This invention was made in view of these points.

Two guide shafts 9 and two racks 10 are vertically fixed to each side of the support body 8, and a horizontal support shaft 11 is horizontally installed at the front part. The support shaft 11 is a drawn material having a cross-sectional shape and having a horizontally long flat surface 11a along the moving direction of the support body 8 on the outer periphery. The front rank 10 is meshed with the gear 5, and the rear rack 10 is meshed with the idler gear 12 that is meshed with the gear 5. The idler gear 12 is rotatably supported by the side plate 1. Further, guide members 13 and 14 for slidably holding either the guide shaft 9 or the rack 10 are fixed to the side plate 1 6 Spring 15 is attached to both sides of the support body 8 and both ends of the drive shaft 6. is installed. A ribbon guide 18 is provided to hold the ribbon 17 pulled out from the cassette case 16 which is removably placed on the support 8.
1 is formed with a U-shaped groove 18a that is slidably fitted into the groove 18a. The cassette case 16 is provided with a take-up shaft 19 connected to a ribbon drive shaft (not shown).

ド１８も連動し、リボン１７が上下方向ヘシフトする。In such a configuration, printing is performed by moving the carrier 21 and driving the dot printer head 20. Also,
When the pulse motor 3 is rotated, the support body 8 moves together with the cassette case 16 in a linear direction perpendicular to the feeding direction of the ribbon 17, and the ribbon guide 18 held on the support shaft 11 is also linked to this movement, so that the ribbon 17 is moved in the vertical direction. shift to
このように、支持体８、リボンガイド１８、カセットケ
