Abstract

PURPOSE:To ensure a simple construction, enable the tension on a motive power transmitting means to be secured to a fixed value and make it possible to eliminate the need for a tension-adjusting operation, by turnably fitting a motive power generating part to a frame, and energizing the motive power generating part in the direction for applying a tension on the motive power transmitting means by an elastic means fastened to the motive power generating means. CONSTITUTION:A driving pulley shaft 9 is fixed to a motor 7 perpendicularly to an upper face (in the figure) of the motor 7, and a driving pulley 8 is rotatably supported by the shaft 9 through a bearing 15. A belt 8 is fitted to a driven pulley 13 and the driving pulley 8, and the motor 7 is rotated in the direction of an arrow 21 with a projection 7-c as a center by s tension spring 10, and a fixed tension corresponding to the spring force and the displacement of the spring 10 is exerted on the belt 12. A pinion 11 fixed to an output shaft of the motor 7 is engaged with the driving pulley 8 to transmit the driving force of the motor 7. The pinion 11, the driving pulley 8, the bearing 15 and the like constitute a mechanism for transmitting the motive power from the motor shaft 9 to the belt.

リッジ駆動機構を提供する事が可能となった。As described above, the power generation section is equipped with a transmission mechanism that transmits power to the power transmission means, the power generation section is rotatably attached to the frame, and the elastic means is locked to the power generation section. Since this elastic means biases the power generating section in the direction of applying tension to the drilling force transmission means, it is possible to maintain a constant tension in the power transmission means with a simple configuration, and this allows for the reduction of tension during assembly or changes over time. It has become possible to provide a high-quality, inexpensive printer carriage drive mechanism using 0T bait, since the tension adjustment work that was conventionally required is irregular when the tension changes.
