摘要： A switch is provided which successively switches contacts at a timing sufficiently quick with respect to reproduced signals in reproducing a magnetic tape on which digital recording is effected, and which switches contacts at similar timing in reproducing a magnetic tape on which analog recording is effected. On signals provided through this switch and through an analog-digital converting circuit, processing such as waveform equalization corresponding to the type of magnetic tape is effected by a digital equalizer. By this digital equalizer, correction of frequency characteristic in accordance with the type of the magnetic tape and correction of frequency characteristic inherent to the head per se are effected.

摘要： A cassette loading apparatus which eliminates a harness for the electric connection to a cassette insertion detecting switch. The cassette loading apparatus comprises a parallel quadrilateral link mechanism including first and second parallel links and third and fourth parallel links. A connecting pin between the first and third links is mounted on a stationary member on which the cassette insertion detecting switch is mounted. A switch operating element is provided on the third link for operating the cassette insertion detecting switch between on- and off-states. The first and second links have elongated holes formed along the length therein, and fitting pins on an actuating lever are loosely fitted in the elongated holes such that the actuating lever extends in parallel to the third link. The actuating lever is mounted for pivotal motion on a cassette holder by means of the first fitting pin and is positioned so as to be operated by a cassette inserted into the cassette holder to move between a cassette non-insertion detecting position and a cassette insertion detecting position to operate the switch operating element.

摘要： In a cassette housing shelf for accommodating various sized cassettes in cassette auto-changers or the like, a guiding block for guiding a small-sized cassette is provided near to a cassette inlet of a cassette housing portion formed upon the shelf. When a large-sized cassette is inserted into the cassette housing portion, the guiding block is automatically removed from the cassette housing portion, and when a small-sized cassette is inserted, the guiding block securely leads the cassette to a predetermined space within the cassette housing portion, so that it is easy to insert the small-sized cassette into the cassette housing portion.

摘要： A cassette holder houses a cassette to be loaded and is arranged to be movable along a substantially horizontal moving path. A cassette detecting member is arranged on the cassette holder and is set at an operative position and a nonoperative position in accordance with the presence/absence of the cassette. A loading mechanism selectively drives the cassette holder so as to load the cassette from an insertion position to a driving position and to unload the cassette from the driving position to an ejecting position. A plurality of lock members are arranged on the moving path of the cassette holder at predetermined intervals so as to lock the cassette detecting member by using one of the lock members when the cassette detecting member is set at the nonoperative position. A control portion allows the loading mechanism to perform loading in response to insertion of the cassette, allowing the loading mechanism to perform unloading in response to an ejecting operation, and switching a loading operation of the loading mechanism to an unloading operation when one of the plurality of lock members locks the cassette detecting member during execution of loading by the loading mechanism.

摘要： A signal recording-reproducing apparatus for use with a cassette includes a reel chassis slidably provided on a main chassis and stoppable at least at three positions, i.e., a standby mode position where the reel chassis is to be loaded with the cassette, a play mode position closer to the cylinder device of the apparatus than the standby mode position, and an empty mode position closer to the cylinder device than the play mode position. In the empty mode, the reel chassis is not loaded with a cassette, and the apparatus has a minimum depthwise length compared to the other modes.

摘要： A magnetic tape drive for insertion of a magnetic tape cartridge of the type having an access door pivotally mounted on a long side of the cartridge is disclosed. The cartridge is inserted through a slot in a front panel of a drawer with the long side of the cartridge parallel to the insertion direction. When the cartridge is inserted, the drawer is in an extended position and is held there by a drawer stopping mechanism. The cartridge is inserted through the slot onto the drawer as far as is permitted by a cartridge stopping mechanism. A rotatably mounted front door on the front panel of the drawer is then rotated closed and the access door of the cartridge is opened by a cam mounted on the front door in response to the rotation thereof. Cartridge and drawer release mechanisms then allow the cartridge and drawer to be fully inserted into a frame of the drive, and as the drawer and cartridge approach their operative positions in the drive, a magnetic head is moved into its operative position with respect to the cartridge in response to movement of the drawer. In addition, means for simultaneously detecting completion of insertion of the cartridge and drawer are provided.

摘要： A recording and/or reproducing apparatus (1) includes a holder compartment (10) for a record carrier (2), a cover (13) which can be closed by hand against spring force to close the holder compartment (10), and a latching member (20) for retaining the cover (13) in the closed position, which latching member is movable by hand against spring force to release the cover (13). When the latching member (20) is actuated by hand to release the cover (13), electrical switching means (31) switches off electrical devices (30) of the apparatus (1) and keeps said devices switched off while the cover (13) is open. The switching means (31) includes a single switch (32) whose switching contacts (33, 34) are set to a first switching state when the cover (13) is closed, in which state the electrical devices (30) can be switched on, and which assume a second switching state when the cover (13) is open, in which second switching state the electrical devices (30) are switched off. The contacts (33, 34) are set to their second switching state via the latching member (20) when the latching member (20) is moved to release the cover (13).

摘要： A magnetic tape cassette recording and playback apparatus, particularly for digital audio tapes, capable of performing a variety of controlled playback and recording operations in accordance with a user-inputted program. The cassettes are stored on shelves in a magazine and selectively extracted and transported to a drive unit for playing and recording. In one mode, the apparatus can carry out continuous recording from one cassette to another, and cassettes can be designated for recording, for instance, of only particular types of music. The cassettes are rewound at the completion of a playing program so as to be ready for the start of search operations for a subsequent program.
