<p>PURPOSE:To obtain position accuracy of a tape guide post with simple constitution securely by abutting directly the lever part, which is a part of the tape guide post holding member which holds the second tape guide post, on the first tape guide post. CONSTITUTION:The first tape guide post 44c and an inclination post 49 move in the clockwise direction at a speed slower than that of a loading ring 40, and when a preceding tape guide post 44a arrives at the position shown in the figure, the 44c also arrives at the position shown in the figure, and after that, the 44a is fixed by the spring force of a press-contacting spring. The 44c is fixed by a V stopper 61. After that, rotation of the loading ring 40 is transmitted to an internal gear 42 through a planet gear 51, and it becomes the fixing force of the 44c by extending a spring 43. The second tape guide post 44d abuts on a lever part 58a of a guide post arm 58 and the head part of the 44c when the 44c approximates to the position of the figure, the arm 58 rotates in the counterclockwise direction since the 44c is fixed by the V stopper 61, and the arm 58 is fixed at the prescribed position.</p> |
