A tape recorder includes a cassette holder for holding therein a tape cassette which is inserted in a direction parallel to the direction of movement of a slide shutter of the tape cassette, an arm-like shutter opening member for opening the slide shutter of the tape cassette, a slide member movable between a first position in which the tape cassette is latched on the slide member, and a second position in which the tape cassette is fully received in the cassette holder, and a control plate, connected with the slide member and engageable with the shutter opening member, for controlling the operation of an actuating pin of the shutter opening member such that when the slide member is disposed in the first position, the actuating pin is held on the outside of the cassette holder, and when the slide plate moves from the first position toward the second position, the actuating pin is able to move into the cassette holder and then engage and open the slide shutter of the tape cassette as the tape cassette is advanced by the slide member.

Tape recorder having a cassette-shutter opening mechanism

A disc magazine has plural partition plates (3) piled up in the opening (2) of the magazine case (1) Making plural slots (90), and plural disc carrier (10) to be slid toward the opening (2), and plural elastic stoppers (13) for guiding standard or larger disc (4) over the disc carrier (10) while stopping smaller disc (34) by the inside (front) arc edge (11) of the disc carrier (10), so that plural discs of different sizes can be received in the plural slot in a manner that the front edges of the received discs of different sizes are on substantially equal positions in all the slots (90) in the opening (2).

Disc magazine

A tape cassette which can be recorded and played back on both sides or in opposite directions has a lid having a pair of side arms pivotally mounted on lateral sides of a cassette casing for opening and closing a front opening in the cassette casing. The lid is normally held in a closed position by means of springs which normally urge pivot pins on the side arms toward a rear side of the cassette casing. The tape cassette also has protective plates integrally projecting in a forward direction from the lateral sides of the cassette casing in covering relation to the side arms, respectively. The protective plate protects the side arms against intentional or accidental engagement with a finger or a cassette recorder, thereby preventing the lid from being easily opened. The cassette recorder for use with the tape cassette includes abutments for engaging distal ends of the protective plates for accurately positioning the tape casette as inserted in the cassette recorder.

Tape cassette and cassette recorder using the same

This invention provides a tape cassette with a cover movable for opening-closing provided in front of cassette halves, which is suitable particularly as an audio tape cassette. The tape cassette of this invention has a cover which makes opening-closing of the front opening part of the cassette body by its turning up- or down-ward, and an engaging holes with which the rotary shafts provided on the cover freely engage being provided in the sides of the aforementioned cassette body, said engaging hole having two sides tapering toward rear of the cassette body, and includes a means for urging the aforementioned rotary shafts of the cover to the rear of the cassette body. This structure permits opening of the front opening part of the tape cassette by turning the cover, whether the tape cassette is inserted in a cassette recorder with its front face (face A) or back face (face B) turned upward.

Tape cassette

A cassette type magnetic recording and reproducing apparatus provided with a means to indicate the amount of progress of the cassette tape. The indicating means is adapted to be reset to the zero position in association with the action of bringing a tape cassette for the recording or playback either into or out of its preset playback position.

Cassette type magnetic recording and reproducing apparatus

A magnetic recording and reproducing apparatus having a cassette tape comprises head base controlling mechanism, and holding case and provides the following three functions: keeping a tape in contact with a recording and reproducing head and an erasing head to such a degree as not to cause trouble for detecting or erasing the recorded content during fast forwarding or rewinding speed of a tape by the reproducing or erasing head, making it possible to record and reproduce at a constant forwarding speed by advancing the head within the cassette, and also making it possible to mount or demount the cassette by completely withdrawing the head advanced within the cassette therefrom.
