グ装置。 In a tape loading device configured to rotate a rotary arm around a spindle and load the tape onto a tape optical path using a tape guide provided on the rotary arm, the tape is driven by a motor to load the tape around the spindle. A rotating cam plate rotated by the rotating cam plate, a fixed cam plate arranged parallel to the rotating cam plate, and a cam plate inserted into the cam grooves provided in the rotating cam plate and the fixed cam plate, respectively, and parallel to the spindle. A guide pin is arranged and movable within a certain range in the longitudinal direction of the rotary arm and is moved in a circular motion integrally with the rotary arm. Therefore, the guide pin is moved in a circular motion around the support shaft along the cam groove of the fixed cam plate to rotationally drive the rotary arm, and when the rotary arm is rotated to a predetermined position, the guide pin is moved to the above position. A tape loading device configured to fix the rotary arm at the predetermined position by positioning by positioning portions of cam grooves of a fixed cam plate and a rotary cam plate.
