Claims

[Claims for Utility Model Registration] 1. The printing head 58 is placed and the platen 3
A carriage 55 movably arranged along the
and a carriage drive mechanism B that applies a force for moving the carriage 55 along the platen 32, and prints on printing paper on the platen 32 while moving the carriage 55 along the platen 32. The carriage drive mechanism is disposed at one end of the carriage movement range,
a drive pulley 82 rotationally driven by a drive motor 78; a support member 85 disposed movably along the carriage movement direction on the printer frame 10 at the other end of the carriage movement range; and the support member 85. a driven pulley 89 rotatably supported above; a belt 91 suspended between each of the pulleys 82 and 89 and partially fixed to the carriage 55; A biasing member 92 is disposed between the support member 85 and the frame 10 to bias the belt 91 to move away from the drive pulley 82, and the biasing member 92 applies tension to the belt 91. A carriage drive device for a printer, characterized in that: 2. The frame 10 has a guide groove 84 extending in the carriage movement direction, and a mounting groove 84a that communicates with the guide groove 84 on the driving pulley 82 side of the guide groove 84 and has a larger outer diameter than the guide groove 84.
The support member 85 includes a protrusion 86a that penetrates the mounting groove 84a and can be placed below the frame 10, and the protrusion 86a is connected to the support member 85 and the inner surface of the guide groove 84. The protrusion 86a passes through the mounting groove 84a to attach the frame 1 to the frame 1.
A carriage drive in a printer according to claim 1, wherein the support portion 85 is disposed so as to be movable along the guide groove 84 together with the guide groove 86b while being disposed below the guide groove 84. Device.
