<p>PURPOSE:To attain sure and smooth coupling between a threader pin and a leader block by providing a guide member engaged with the threader pin to a cartridge tape holding mechanism. CONSTITUTION:In moving a tape moving base 5 supporting a cartridge tape 1 to the left in figure by a drive mechanism 6, the thinned part at the lower part of the threader pin 3 is introduced to the V-shaped opening of a guide piece 4. Thus, the notch of a leader block 2 is engaged with the upper part of the step of the threader pin 3. In moving the tape moving base 5 holding the cartridge tape 1 downward in figure by the next operation of the drive mechanism 6, the notch of the leader block 2 engaged with the upper part of the step of the threader pin 3 is coupled to the step of the pin 3. Since the guide member 4 engaged with the threader pin 3 to the cartridge tape holding mechanism is provided in this way, the coupling between the threader pin 3 and the leader block 2 is ensured and smoothed.</p> |
