Claims

[Scope of utility model registration request]

A cassette holder of a video tape recorder that supports and transports a loaded tape cassette is moved forward and backward from the cassette insertion position to the cassette normal mounting position via a loading motor, and the cassette holder is provided protruding from the lower surface of the bottom plate of the cassette holder. A detection arm is attached to the bearing part so that the intermediate part can rotate freely, and a detection arm is attached to the detection arm at one end sandwiching the intermediate part, which is integrally molded with the detection arm and is in contact with the lower surface of the bottom plate of the cassette holder. A thin spring strip made of a resin material is formed to urge the detection arm to rotate counterclockwise, and a locking portion is formed to be lockable in a locking hole of the guide plate, and the detection arm and other parts are also provided. When the cassette is inserted into the cassette holder in the correct posture, the tip of the detection section integrally molded on the end protrudes to the front side of the advancing cassette, and comes into contact with the slope of the detection section as the cassette moves forward, thereby detecting the detection. When the part is rotated clockwise, the locking hole is closed at the same time.
The locking portion is removed, the cassette is completely inserted into the insertion position of the cassette holder, and the circuit of the opening motor is closed. A cassette mounting device characterized in that it is provided with the above-mentioned detection section.
