A recording-medium mis-recording preventing mechanism for preventing recording from being made by mistake on a recording medium loaded in a recording unit, comprises: a push switch for detecting whether the recording medium is recordable or not; and an arm portion. The arm portion includes: a first arm member pivoted on the recording unit and having a detection portion for abutting against a judgement claw provided on the recording medium so as to be removable by bending; a second arm member for pushing the push switch; a thin plate portion for connecting the first arm member and the second arm member; a spring provided between the first arm member and the second arm member for urging the second arm member in the direction to push the push switch; and a plate spring portion provided on the first arm member for making the arm portion return to a position in which the arm portion is to be positioned when no recording medium is loaded.

A magnetic tape apparatus having a bearer formed so as to be reciprocatable in the front-rear direction between a cassette insertion position and a cassette mount position on a chassis for inserting a tape cassette, and a rotating cam provided on the chassis for driving the bearer through an interlocking mechanism with a clutch. In the magnetic tape apparatus, the clutch is turned off to release the interlocking mechanism between the bearer and the rotating cam when the bearer is advanced from the cassette mount position to the cassette insertion position, while the clutch is turned on to establish the interlock between the bearer and the rotating cam when the bearer is retreated from the cassette insertion position to the cassette mount position.

A loading mechanism in a video cassette deck comprising a cassette moving mechanism 100 for moving a cassette receiving portion 200 between an initial location and a running location. The cassette moving mechanism 100 has a slide arm 120 horizontally slidably attached on one of a pair of wall portions 110 provided on both left and right sides of the cassette receiving portion 200, a driving portion for sliding the slide arm 120, a cassette driving gear 130 which is rotatably supported on the wall portion 110 to which the slide arm 120 is attached and which is connected to the cassette receiving portion 200 through a groove portion 112 formed in the wall portion 110, and a door arm 140 for transmitting the motion of the slide arm 120 to a door. The cassette loading mechanism is designed so that the door is opened before the cassette receiving portion 200 is moved when the cassette receiving portion 200 in the running location is moved into the initial location.

A device for securing a pinch roller support arm to a chassis of a magnetic tape apparatus. In the device, the chassis includes a round hole which is formed such that it extends through the chassis, and a securing part is outsert molded in the chassis in such a manner that the securing part extends through the round hole. After the pinch roller support arm is fitted with a support shaft provided on and projected from the chassis and a projection provided on the pinch roller support arm is fitted into a fitting hole formed in the chassis, by rotating the securing part around the round hole, the securing part is engaged with the projection.

Device for securing a part to a chassis

A device for exchanging a tape drive mode so to maintain a satisfied timing by which a tension mechanism for applying a tension to a tape between tape reels is kept to its tension place until the tape transport by a capstan roller together with a pinch roller is exerted after the power transmission is exchanged to either one of the tape reels for shifting the device from the playing/recording mode to the rewinding mode.
