摘要： 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.

摘要： 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.
