A cover apparatus of a cassette tape recorder comprising first and second covers rotatable to be openable and closable with respect to a body of the tape recorder. The first cover has a holder to encasing a tape cassette so that the tape cassette encased in the holder is rotatable in accordance with the rotation of the first cover, a length of the first cover in longitudinal directions being smaller than that of the tape cassette so that a portion of the tape cassette protrudes from the first cover when being encased in the holder. The second cover is arranged to be engaged with the first cover to be rotatable together with the first cover and movable along a surface of the first cover. The second cover, together with the first cover, rotates to cover the entire tape cassette when the first cover is closed with respect to the tape recorder body, and further the second cover moves with respect to the first cover when the first cover is opened with respect thereto, so that the portion of the tape cassette protrudes from tip portions of the first and second covers. This arrangement allows the user to easily take out the tape cassette from the tape recorder.

Two-part rotatable cover apparatus for tape cassette with lock mechanism

A cover apparatus of a cassette tape recorder comprising first and second covers rotatable to be openable and closable with respect to a body of the tape recorder, the first cover having a holder to encase a tape cassette so that the tape cassette encased in the cassette holder is rotatable in accordance with the rotation of the first cover. The first and second covers are coupled to each other through a slider engaged with the second cover and slidable along a side surface of the first cover. The first cover rotates to cover the entire tape cassette in cooperation with the second cover when the second cover is closed with respect to the tape recorder body. The second cover vertically moves by a predetermined height with respect to a surface of the first cover in accordance with a first sliding operation of the slider when the first cover is opened by a first predetermined angle with respect to the tape recorder body and horizontally moving a predetermined distance with respect to the surface of the first cover in accordance with a second sliding operation of the slider when said the cover is opened by a second predetermined angle greater than the first predetermined angle so that a portion of the tape cassette protrudes from a tip portion of the second cover. This arrangement allows the easily insertion and removal into and from the holder of the first cover.

Two-part slidable cover apparatus for tape cassette with lock mechanism

A cover opening/closing device prevents backlash when the cover is closed, by engaging the cover with a lock cam and urging the lock cam to be rotated into positions by a toggle spring. For this object, this device comprises a lock cam which is rotated about a rotational shaft provided in a main body, an operation lever which rotates the lock cam to open the cover, and a toggle spring which is designed to maintain the lock cam in urged states at the respective cover-opened and cover-closed positions. The lock cam can be kept urged in the cover-closed state.
