Claims (1)

[Claim for Utility Model Registration] A tape guide block is placed on a guide rail provided along the outside of a rotating head drum, and a guide pin provided on the lower surface of the tape guide block is placed below a guide groove provided on the guide rail. A ring gear is rotatably provided on the outer periphery of the rotary head drum, one end of the connecting link is connected to the ring gear via a spring, and the lower end of the guide pin is inserted into the guide pin insertion hole provided at the other end of the connecting link. The tape guide block is connected by passing through it from above, and the rotation of the ring gear drives the tape guide block via the spring and the connecting link, so that the tape guide block is moved forward from the backward movement position to the forward movement position along the guide rail. In a tape loading device configured to pull out a tape from a tape cassette and load it around a rotating head drum, the tape guide block has a guide pin protruding from the lower end thereof in a direction perpendicular to the axis of the guide pin. A slit for inserting the protrusion is provided on the inner periphery of the guide pin insertion hole at the other end of the connecting link, and when the lower end of the guide pin is passed through the connecting pin insertion hole from above, the protrusion is inserted. The tape guide block is inserted through the slit, and then the tape guide block is rotated at a predetermined angle about the guide pin and placed on the guide rail, thereby displacing the protrusion from the slit and causing the protrusion to move. A tape loading device characterized by being configured to prevent the other end of the connecting link from coming off from the lower end of the guide pin.
