Abstract
The dimension in the height direction of a reel braking mechanism to be disposed on the side of an S-side reel table in a video tape recorder is made small while making it difficult to disassemble an assembled state. The dimension in an axis line direction of a pin that engages an elongated hole of a brake member of a brake arm is lengthened, thereby penetrating the brake member and extending downward. The extended portion of the pin is made to pass through a cut formed in an edge of a slide chassis.
Claims14
A recording and reproducing apparatus performing recording and/or reproducing according to a helical scanning system, in which a tape-shaped recording medium is helically wound around a head drum and scanned with a rotating head, characterized in that:
- a brake arm is disposed in proximity to a supply-side reel table with which a supply-side reel reeling out the tape-shaped recording medium engages, a brake member that includes a non-circular hole for coupling to a pin on the brake arm such that the brake member is swingable about the pin with a swinging center that is movable within the hole, the brake member is urged by an urging member incorporated on the brake arm in a brake releasing direction;
- and
- when the supply-side reel table is driven to rotate in a direction to take up the tape-shaped recording medium, the brake member moves to a center of the supply-side reel table and is separated from the supply-side reel table by the urging member to release the brake member.
A recording and reproducing apparatus performing recording and/or reproducing according to a helical scanning system, by helically winding a tape-shaped recording medium around a head drum and by helically scanning the tape-shaped recording medium with a rotating head, characterized in that:
- a supply-side reel table and a take-up side reel table, with which a supply-side reel reeling out the tape-shaped recording medium and a take-up side reel taking up the tape-shaped recording medium engage, respectively, are mounted on a slide chassis capable of approaching and separating from the head drum;
- a brake lever is disposed in proximity to the take-up side reel table with which the take-up side reel taking up the tape-shaped recording medium engages, the brake lever releases braking when the reel table rotates in a taking-up direction and performing a braking operation when the reel table rotates in an opposite direction to the taking-up direction;
- and
- restricting means for restricting the brake lever in an inactive state is mounted on the slide chassis, a release member is mounted on a main chassis on which the head drum is mounted, and restriction of the brake lever by the restricting means is released by the release member when the slide chassis moves to a head drum side, the restricting means continually applying a force to the brake lever, and the brake lever being released from restriction when a force applied by the release member overcomes the force applied by the restricting means.
A recording and reproducing apparatus performing recording and/or reproducing according to a helical scanning system, by helically winding a tape-shaped recording medium around a head drum and by helically scanning the tape-shaped recording medium with a rotating head, characterized in that:
- a tape cassette wound with the tape-shaped recording medium therein is moved in a direction approaching the head drum by a slide chassis to perform the recording and/or the reproducing with the tape-shaped recording medium pulled out from the tape cassette;
- a reel brake for braking a reel wound with the tape-shaped recording medium in the tape cassette is provided, the reel brake performing a braking operation when pulling out the tape-shaped recording medium from the reel, the reel brake releasing the braking operation when taking up the tape-shaped recording medium;
- restricting means for restricting the reel brake by coercively releasing the reel brake during a movement of the slide chassis equipped with the tape cassette provided on the slide chassis, the restricting means continually applying a force to the reel brake;
- and
- release means for releasing restriction by the restricting means when the slide chassis equipped with the tape cassette moves to a head drum side provided on a main chassis mounted with the head drum,
- the reel brake being released from restriction when a force applied by the release means overcomes the force applied by the restricting means.
