Claims (1)

[Claims for Utility Model Registration] (1) A rotating drum provided on a chassis, a tape guide block that moves between a loading position and an unloading position along a predetermined path provided on the chassis, and A tape guide that is erected, a tension arm that is pivotally supported by the chassis and moves between the loading position and the unloading position, a tension ball that is erected thereon, the rotating drum, the tape guide, and the tension arm. The tape loading mechanism consists of a magnetic tape wrapped around a tape pole, and a loading cam member that obtains a predetermined mode position by the driving force of a motor, etc., and a loading cam that moves by engaging with this loading cam member. a transmission member; a loading link that engages with the loading transmission member and moves the tape guide block between the loading position and the unloading position; and a loading link that engages with the loading transmission member and moves the tape guide block between the loading position and the unloading position; A tape loading mechanism characterized by having a swinging arm that comes into contact with the arm and maintains the position of the tension arm. (2) The swing arm is pivotally supported on a shaft provided upright on the chassis, and a second contact portion that contacts the tension arm during unloading is formed concentrically with the shaft. A tape loading mechanism according to claim 1 of the utility model registration claim characterized by: (3) The tension arm has a first movement range from the unloading position to the intermediate standby position, and a second movement range from the intermediate standby position to the loading position.
The tension arm moves through a range of movement, and in the first range of movement, the swing arm moves by contacting the tension arm, and in the second range of movement, the tension arm engages with the loading cam member. The tape loading mechanism according to claim 1, wherein the tape loading mechanism moves in response to a mode switching member.
