ようにしたものが存する。2. Description of the Related Art Conventionally, a support for holding a cassette case accommodating a ribbon is provided rotatably up and down, and a wire is fastened to both sides of a ribbon guide that slidably holds the ribbon facing the printing unit. Secure both ends of the wire to both sides of the support,
One in which a support is rotated around a fulcrum using a motor or electromagnet as a drive source, and ribbon movement is linked to the vertical movement of this support to switch ribbons, thereby performing multicolor printing. Exist.
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

上下に混色が発生する。Problems to be Solved by the Invention However, when the support is frequently moved up and down at high speed, the ribbon guide suspended by the wire vibrates, and the operation is not stable until the vibration is stopped. On the other hand, there are 4 ribbons for multicolor printing.
Some of them are color-coded into more than one color zone. When printing multiple colors, print with one selected zone, or multiple zones are overlapped on the same print line to perform printing operations, so the ribbon is placed at the correct position. It is necessary to move at high speed, and the switching frequency is extremely high. Further, there is a demand to make the print width of each zone as narrow as possible, and the margin for the print width of each zone is extremely small. Therefore, if the shift amount of the ribbon is slightly incorrect, 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、リボン

いる。Then, a support 8 is provided as shown in FIGS. 1 and 2. Two guide shafts 9 and two racks 10 are vertically fixed on both sides of the support 8, and a horizontal support shaft 11 is laterally provided at the front portion. This support shaft 11 has a support 8 on the outer periphery.
Is a drawing material having a D-shaped cross section having a horizontally long flat surface 11a along the moving direction of. The front rack 10 is meshed with the gear 5, and the rear rack 10 is meshed with an idler gear 12 meshed with the gear 5. The idler gear 12 is rotatably supported on the side plate 1. Further, the side plate 1 has a guide shaft 9 and a rack 10.
Guide members 13 and 14 for slidably holding any of the above are fixed. Springings 15 are stretched on both sides of the support 8 and both ends of the drive shaft 6. A ribbon guide 18 for holding a ribbon 17 pulled out from a cassette case 16 which is detachably mounted on the support 8 is provided, and the ribbon guide 18 is slidably fitted on the spindle 11. A U-shaped groove 18a is formed. The cassette case 16 is provided with a winding shaft 19 connected to a ribbon drive shaft (not shown).

ント機構26が形成されている。Further, a printing movable body 22 including a dot printer head 20 which is a printing unit and a carrier 21 which is equipped with the printing head 20 and is slidably held by the carrier shaft 7 is provided.
The ribbon guide 18 is also held by the carrier 21 so as to be vertically movable. The dot printer head 20 is formed with a protrusion 23 slidably held by the drive shaft 6. Further, saw-toothed pieces 24 having a plurality of teeth arranged vertically are integrally formed on both sides of the ribbon guide 18, and locking claws 25 that elastically engage with these saw-toothed pieces 24 are provided. The saw-toothed piece 24 and the locking claw 25 are attached to the carrier 21 to form a day tent mechanism 26.

動し、リボン17が上下方向へシフトする。In such a structure, printing is performed by moving the carrier 21 and driving the dot printer head 20. Further, when the pulse motor 3 is rotated, the support 8 moves together with the cassette case 16 in the linear direction orthogonal to the feeding direction of the ribbon 17, and this operation also interlocks with the ribbon guide 18 held by the support shaft 11, so that the ribbon 17 is moved. Shift up and down.
このように、支持体８、リボンガイド18、カセツトケー

に定めることができる。In this way, the support 8, the ribbon guide 18, and the cassette case 16 move in the linear direction orthogonal to the feeding direction of the ribbon 17, so that the ribbon at the tip of the dot printer head 20 is controlled by controlling the rotation angle of the pulse motor 3. The shift amount of 17 can be set to an accurate value that matches the shift amount of the rack 10.

行わせることができる。Further, since the ribbon guide 18 is held by the support shaft 11 having high rigidity, it does not vibrate in the vertical direction when the support 8 is switched. Moreover, since the support 8 is urged by the spring 15 together with the rack 10, even if there is some backlash between the gear 5 and the idler gear 12 and the rack 10, when the support 8 is frequently moved up and down. Very little vibration and stable quickly. Therefore, high speed printing can be performed.
このように、リボン17のシフト量が正確で、リボンガイ
ド18のリボン切替方向の振動が防止されるので、多色印
字に際して混色を防止することができる。As described above, since the shift amount of the ribbon 17 is accurate and the vibration of the ribbon guide 18 in the ribbon switching direction is prevented, it is possible to prevent color mixing in multicolor printing.
