<p>PURPOSE:To lower accuracy in fabricating a tape loading mechanism and to simplify its fabricating stages by position-regulating either a 1st tape pulling-out member or a 2nd pulling-out member at an unloading completing position and positioning the 1st and 2nd tape pulling-out members. CONSTITUTION:The 1st and 2nd tape members 39a and 39b pull out the tape of a tape cassette to wind around a cylinder 37. The 1st tape drawing member 39a is allowed to abut on the one end of a 1st guide hole 38a at the loading completing position to control position. Therefore, the 1st and 2nd tape pulling- out members 39a and 39b are positioned at the unloading completing position. Simultaneously, the 1st and 2nd tape pulling-out members 39a and 39b are energized toward the loading start position at the unloading completing position via a spring member. Therefore, the accurate positioning can be persuaded regardless of accuracy in fabricating the tape loading mechanism including a mode switching cam 32 that drives the 1st and 2nd tape members 39a and 39b. Thereby, in accuracy fabricating the mode switching cam 32 can be lowered and the fabricating stages can be simplified.</p> |
