Claims

[Claims for Utility Model Registration] The loading means guides a slider provided on the upper part on a guide rail and moves the tape from the backward movement position to the forward movement position, so that the tape is moved onto the loading path by the loading means. In a tape loading device configured to load a tape, the drive pulley is rotatably driven by a motor, and the drive pulley is disposed on the same axis as the drive pulley and is rotatably driven by the drive pulley through a pin and an arcuate long hole. a driven pulley, a wire having both ends fixed to the drive pulley and the driven pulley and wound around the guide pulley, a part of the wire being fixed to the slider, and the pin being fixed to the length of the guide pulley. A spring for removing slack in the wire is provided to urge the driven pulley to rotate in one direction relative to the drive pulley so as to abut one end of the hole, and the slider is rotated in one direction between a backward movement position and a forward movement position. When moving, the driven pulley is rotationally driven by the drive pulley with the pin in contact with the other end of the elongated hole against the spring, thereby causing the driven pulley to rotate the wire. The slider is moved by pulling the slider, and when the slider is moved in the other direction between a backward movement position and a forward movement position, the driven pulley is caused to follow the drive pulley by the spring. and the wire is pulled by the drive pulley to move the slider, and the slider moved in the other direction is stopped and the wire between the slider and the driven pulley is loosened. 1. A drive device for a tape loading device, characterized in that when a wire is slackened, the driven pulley is rotated in the opposite direction by the spring to take up slack in the wire.
