Claims

[Scope of utility model registration request]

An inner box that holds a cassette, a guide pin provided on the inner box, a side plate that has a guide groove that guides the guide pin and supports the inner box by the guide groove, and a side plate that is rotatably supported by the side plate. a first gear, an arm fixed to the first gear and driving the guide pin, a second gear that engages directly or indirectly with the first gear, and a drive pin provided on the second gear. , a worm wheel rotatably inserted into the shaft of the second gear; a window provided on the worm wheel and into which the drive pin is inserted; the inner case moves through the drive pin in a direction opposite to insertion. a spring for biasing the worm wheel, a motor for driving the worm wheel, and a claw fitted into the worm wheel so that the side surface of the worm wheel can slide in a direction perpendicular to the axis and facing the window. a slider with
The slider includes a cam pin provided on the slider, and a groove cam that guides the cam pin and slides the slider to engage and disengage the pawl from the drive pin. In the front loading mechanism, the drive unit moves the box in the insertion direction to mount the cassette at a predetermined position, and rotates the motor in the opposite direction to move the inner box in the counter-insertion direction to eject the cassette. An inclined surface is provided on the tip end surface of the pin, and an inclined surface is provided on the tip sliding side of the claw of the slider, and the claw of the slider rides on the drive pin using both of these inclined surfaces. Front loading mechanism.
