摘要： In a cassette loading device in an apparatus for use with a record bearing medium housed in the cassette which is provided with at least one window for exposing a portion of the medium and a movable cover member for the window, when the cassette is moved between a first position to receive and hold the cassette and a second position to place the cassette at a predetermined loading position, an opening and closing device is made to engage with the movable cover member thereby effecting the opening and closing of the window of the cassette corresponding to an action to insert the cassette or take out the same and, at the same time, the engagement between the opening and closing device and the movable cover member is controlled between the first position and the second position.

摘要： In the recording or reproduction apparatus using a disc cassette having a shutter releasably locked in the closed position, a mechanism for opening and closing the shutter as the disc cassette is inserted into, and pulled out of, the apparatus has its closing member made by bending an elastic line wire to such a form that the locking means can pass under it without being operated to release the shutter, but its engagement with the shutter is maintained against the load however large, when the shutter is closed.

摘要： A record bearing medium cassette loading device for a recording and/or reproducing apparatus including: a cassette carrying device, which includes an elastic member, and a cassette receiving member arranged to have the cassette held between them and which is arranged to be driven to move in the direction of insertion of the cassette; a position restricting member which restricts the position the elastic member in the cassette carrying device; and a driving mechanism for driving the cassette carrying device in the cassette inserting direction. In loading the cassette, the record bearing medium containing cassette is manually pushed in between the elastic member and the cassette receiving member of the cassette carrying device until the elastic member is restricted by the restricting member. Following that, the driving mechanism performs an inward pulling action on the carrying device. During this pulling action, the cassette holding force of the carrying device is increased by causing the restricting member to act on the elastic member.
