A power supply device of a tape-end detecting sensor for a tape recorder. The power supply device comprises a reel cover disposed on a sub-chassis, with a tape-end detecting sensor being seated on the reel cover for detecting the passing of a terminal end of a magnetic portion of a magnetic tape, a first power transmitting member mounted in the reel cover to be connected to the detecting sensor and having a first contacting portion, and a second power transmitting member disposed on the sub-chassis and having a second contacting portion that comes into contact with the first contacting portion when the reel cover is mounted on the sub-chassis. The power supply device further comprises a resilient pressing member integrally formed with the sub-chassis, for resiliently pressing the second contacting portion toward the first contacting portion to improve a contacting force between the first and the second contacting portions.

A locking device for a tape cassette housing of a tape recorder comprises a locking recess and a locking protrusion respectively provided in sides of a tape cassette housing and a deck chassis and corresponding to each other, thereby fastening a tape cassette housing to the deck chassis, the tape cassette housing resiliently coming into contact with the deck chassis as a tape cassette is loaded. In here, around external circumference of the locking protrusion is formed at least one edge, and an end of the edge comes into contact with a corner of the locking recess right before the locking protrusion is inserted into the locking recess. Accordingly, the locking protrusion comes into linear contact with the corner of the locking recess in loading/unloading operations of the tape cassette so that the stopping of the ascending and descending movements of the tape cassette housing is prevented during the loading/unloading operations of the tape cassette.

Disclosed is a reel clutch of a tape recorder. A plate spring is positioned between a reel gear and a reel disc of a reel disc assembly which is mounted on a deck of a tape recorder, and a stopper reel is provided on the reel disc to restrain the engaging height of the plate spring so that a torque is generated by the frictional contact between the reel disc and the plate spring, whereby assembly productivity can be enhanced and manufacturing costs can be reduced.

A pole base assembly driving device for a tape recorder is disclosed. Manufacturing of decks becomes simpler and at lower cost. The pole base assembly driving device has a loading gear rotatably disposed on the deck, and rotated by a driving force which is transmitted from a driving source installed on the deck. The pole base assembly further comprises an elastic rod connected by one end to the loading gear, and connected by the other end to a link member which is connected with the pole base assembly. The elastic rod is preferably made of a material which is elastically bendable by an external force, and preferably comprises a deformation restricting means for restricting a deformation of the elastic rod when the elastic rod is deformed by the rotation of the loading gear, such as protrusions on the concave side of the rod when deformed and a reinforcement member. As a result, the number of parts and manufacturing cost is reduced, and deterioration of durability due to breakage of parts can be avoided.

A deck mechanism for a magnetic recording/reproducing apparatus comprises a main deck provided with a head drum, a capstan motor, and a sub-deck installed on the main deck to be loaded/unloaded. The sub-deck is provided with a pair of reel discs, onto which tape reels of a tape cassette are seated; a pole base loading unit; a pinch roller unit for compressing the tape against a spindle of the capstan motor when the sub-deck is loaded; a brake unit; a main sliding member mounted on the main deck to be capable of reciprocatingly sliding, the main sliding member controlling the driving of the pinch roller unit; and a main cam gear mounted on the main deck. The main cam gear causes the sub-deck, the pole base loading unit, the brake unit, and the main sliding member to perform linked movements while the main cam gear is rotationally driven.

A power supply device of a tape-end detecting sensor for a tape recorder. The power supply device comprises a reel cover disposed on a sub-chassis, with a tape-end detecting sensor being seated on the reel cover for detecting the passing of a terminal end of a magnetic portion of a magnetic tape, a first power transmitting member mounted in the reel cover to be connected to the detecting sensor and having a first contacting portion, and a second power transmitting member disposed on the sub-chassis and having a second contacting portion that comes into contact with the first contacting portion when the reel cover is mounted on the sub-chassis. The power supply device further comprises a resilient pressing member integrally formed with the sub-chassis, for resiliently pressing the second contacting portion toward the first contacting portion to improve a contacting force between the first and the second contacting portions. Accordingly, the contacting force between the first and the second contacting portions can be improved without employing a separate resilient pressing member and thus, the number of manufacturing process and the manufacturing cost can be decreased.

A housing structure of a tape player and recorder having a cassette housing and two pairs of link members is installed on both side walls of a deck of the tape player and recorder. The cassette housing is supported on the deck by the pairs of the link members. One of the pair of link members is integrally formed with a shaft connected to one end of the link members in a monolithic structure.

A hub lock releasing structure for a tape recorder has a releasing pin for releasing a hub from a locked state by pressing a hub locking member installed on a tape cassette in one direction as the tape cassette settles on a deck. The releasing pin is integrally formed with the deck. In the hub lock releasing structure, since the releasing pin is integrally formed with the deck, the number of necessary components can be reduced and the assembly process can be simplified. A method of fabricating a releasing pin for the hub lock releasing structure comprises providing a deck in the tape recorder for receiving a tape cassette, partially cutting a portion of the deck, and bending the cut portion of the deck upward to form the releasing pin.

A reel braking apparatus for a tape recorder selectively brakes a reel disk assembly, which includes a reel disk and a reel gear installed on a deck, according to an operational mode. The apparatus includes a clutch member supported by a rotation shaft installed on the deck, a gear member installed coaxially relative to the clutch member so as to rotate by being engaged with the reel gear, and a clutch spring installed between the gear member and the clutch member for restricting rotation of the gear member so that the gear member can rotate in one direction according to a rotational direction of the reel gear. The clutch member and the clutch spring are coupled to each other, and this allows the gear member installed for engagement with the reel gear of the reel disk assembly to rotate in one direction only. Thus, as soon as the rotation of the gear member changes according to a change in rotation direction of the reel gear from a forward direction to a reverse direction, the rotation of the gear member is restricted by the clutch spring, and rotation of the reel gear is stopped.

A cassette housing assembly of a tape recorder is provided including a cassette housing having an upper surface portion, side surface portions, and a lower surface portion having a fixed stopper formed at one side thereof. The housing forms a space for receiving a cassette. A mobile stopper is installed on the lower surface of the upper surface portion of the cassette housing member to be capable of moving along the lower surface. A spring is coupled to one side of the lower surface of the upper surface portion of the cassette housing member and to one side of the mobile stopper to bias the mobile stopper. The cassette housing assembly minimizes damages to the cassette housing assembly due to incorrect insertion of the cassette can be prevented and a user can easily recognize mis-insertion of the cassette.
