産業上の利用分野
この発明は、プリンタに使用するリボン切替装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a ribbon switching device for use in a printer.
従来の技術
従来、多色の印字リボンが収納されたカセットケースが
載置された載置板を支点を中心に上下方向に回動させ、
印字リボンの任意の色を印字部に対向させて所望の色に
より印字を行なうようにしたプリンタが存する。Conventional technology Conventionally, a mounting plate on which a cassette case containing multicolored printing ribbons is mounted is rotated vertically around a fulcrum.
2. Description of the Related Art There is a printer in which a desired color of a printing ribbon is placed opposite a printing section to print in a desired color.
発明が解決しようとする問題点
しかし、このようなものは、載置板が回動するため、そ

字リボンが痛む問題がある。Problems to be Solved by the Invention However, in this type of device, since the mounting plate rotates, depending on the rotating position, the printing ribbon may not be able to face the printing part parallel to it, or it may not be possible to bring it closer to parallelism. In order to do this, it is necessary to increase the distance between the fulcrum of the mounting plate and the printing section, which poses a problem of increasing the size of the apparatus. Furthermore, there is a device in which only a part of the printing ribbon is shifted in a direction perpendicular to the direction of movement of the carrier at the tip of the printing section, but when switching the ribbon, the printing ribbon wrinkles in the width direction and there is a risk of color mixing. . In addition, since the amount of shift is large in multicolor ribbons, they are easily twisted, and the printing ribbons are frequently switched, which causes damage to the printing ribbon.
この発明はこのような点に鑑みなされたもので、印字リ
ボンを常に印字部に対して平行に対向させて鮮明な印字
状態を得ることができ、しかもリボンのの走行抵抗を小
さくし切替位置を正確に定めて多色印字の際混色を防止
しうるリボン切替装置をうろことを目的とする。This invention was developed in view of the above points, and it is possible to obtain clear printing by always facing the printing ribbon parallel to the printing part, and also to reduce the running resistance of the ribbon and change the switching position. The purpose of the present invention is to provide a ribbon switching device that can be accurately determined and prevent color mixing during multicolor printing.

ア２の移動方向と直交する直線方向へ移動自在に設け。Means for Solving the Problems The present invention provides a cassette case 9 in which a plurality of color-coded printing ribbons 8 are stored in zones 4, 5, 6, and 7.
A guide member 19 that slideably guides a part of the printing ribbon 8 pulled out from the cassette case 9 along the moving direction of the carrier 2 is attached to the tip of the carrier 2 carrying the printing unit 1 and moving back and forth. It is connected to the mechanism 26 and provided so as to be movable in a straight line direction orthogonal to the moving direction of the carrier 2.
印字リボン８の経路を定める複数のリボンローラ２０を
案内部材１９に回転自在に設ける。A plurality of ribbon rollers 20 for determining the path of the printing ribbon 8 are rotatably provided on the guide member 19.

。Therefore, since the printing ribbon 8 is held by the guide member 19 which moves in a straight line direction perpendicular to the moving direction of the carrier 2, it always faces the printing part 1 in a parallel state. Also, although the guide member 19 moves in the switching direction, the printing ribbon 8
Since the path is determined by the ribbon roller 2°, running resistance is small, the printing ribbon 8 quickly follows the switching operation of the guide member 19, and the printing ribbon 8 is prevented from being wrinkled.

A guide member 19 is held by these shafts 18 so as to be movable in a straight line direction perpendicular to the direction in which the carrier 2 moves. Two ribbon rollers 2o are rotatably held on both sides of the guide member 19 to determine the path of the printing ribbon 8 and to make the printing ribbon 8 run smoothly. On both sides of the carrier 2, arms 21 located at the front are connected to shafts 22.
The arm 23 located at the rear is rotatably held by a shaft 24. These arms 21.23, which are paired on one side, are formed with teeth 25 that mesh with each other. Front arm 21

7 every 45", the locking recesses 38, 39, 40, 41 that engage with the roller 34 change, so the shift lever
28 and 29 rotate in the vertical direction about the shaft 33 as a fulcrum. The mounting plate 10 is lifted by the support piece 36 and rises, and the support piece 3
It goes down when 6 goes down. FIGS. 2 and 3 show a state in which the rollers 34 of the shift levers 28 and 29 are engaged with the highest locking recesses 40 to move the mounting plate 10 to the highest position, and FIGS. 4 and 5 2 shows a state in which the roller 34 is engaged with the lowest locking recess 38 and the mounting plate 10 is moved to the lowest position. As the mounting plate 10 moves up and down, the arms 21 and 23 whose teeth 25 engage with each other rotate, and the guide member 19 moves up and down in the linear direction.

る。In this way, since the guide member 19 moves in a linear direction perpendicular to the moving direction of the carrier 2, the printing ribbon 8 can always be opposed to the front end surface of the dot printer head 1 in a parallel state. At this time, since the cassette case 9 moves together with the mounting plate 10 in parallel to the guide member 19, twisting of the printing ribbon 8 can be prevented. In particular, since the printing ribbon 8 has its path determined by the ribbon roller 20, even if the guide member 19 moves, the ribbon roller 20
The rotation quickly follows the switching direction, and as a result,
The printing ribbon 8 runs smoothly and does not wrinkle in the width direction. Therefore, the four color zones 4,5
, 6, and 7 are printed in one zone or multiple zones overlapped to select 7 printing colors, but zones 4, 5, 6, and 7 are positioned at accurate switching positions to prevent color mixing during multicolor printing. .
印字リボン８のシフト量も大きく切替頻度も多いもので
あるが、印字リボン８はしわや捻じれがないので痛みも
少なく長期間使用することができる。Although the printing ribbon 8 has a large shift amount and is frequently switched, the printing ribbon 8 does not wrinkle or twist, so it can be used for a long period of time with little pain.

。Effects of the Invention Since the present invention is constructed as described above, the guide member that holds the printing ribbon is moved in a straight line direction perpendicular to the moving direction of the carrier, so that the printing ribbon is always parallel to and facing the printing section. Moreover, by providing the ribbon roller on the guide member, the printing ribbon can quickly follow the switching operation of the guide member, thereby,
This prevents the printing ribbon from wrinkles and allows the printing ribbon to run smoothly.
It has effects such as being able to prevent color mixing during multicolor printing and increasing the durability of the printing ribbon.
