Title: Magnetic recording/reproducing apparatus
Inventor: SASAKI KENJI
IPC: G11B15/18
Filed: 1994-06-27
Abstract: PURPOSE:To keep the tension of a tape in a running route constant at the time of a recording/reproducing mode and, further, reduce the number of components by a method wherein a tension band is utilized as a supply side main brake. CONSTITUTION:When a spring-loaded arm 24 is at a first position, the actuating force of a tension spring 23 is applied to a tension arm 21 and the tension of a tape 2 which is applied to a tension post 19 is balanced with the tension of a tension band 20. A take-up side tension control mechanism is operated by an operating member so as to make a tension band 26 touch a take-up reel base 14. A pinch roller 10 is pressed against a capstan 9 with a required pressing force. If a capstan motor 8 required revolution in this state, the tape 2 is made to run while its tension is kept constant by a pay-off side tension control mechanism and the recording/reproducing can be carried out.
