Title: Magnetic recording and reproducing device
Inventor: ITO TETSUO
IPC: G11B15/00
Filed: 1988-11-30
Abstract: PURPOSE:To eliminate the need for switching an operation mode and to simplify the operating condition in frame photographing recording by absorbing the sagging of a magnetic tape accompanied with the lowering of tape tension in the finely reverse feeding mode of the magnetic tape with the aid of a sagging preventing member. CONSTITUTION:The rewinding operation of the tape in the midst of a frame photographing operation is performed only by the reverse rotation of a capstan 8 which does not accompany the operation of a supply reel 3 and the sagging caused by the reverse feeding of the tape 1 is absorbed by the sagging preventing member 12 so as to maintain the tape tension. Therefore, the switching of the operation mode of a mechanism, that means, the frequent switching of a brake band 17 from an actuation state to a non-actuation state becomes unnecessary. Thus, a time for frame photographing operation is shortened by a time for switching the operation mode of the mechanism and operability is improved, then the operating condition in frame photographing recording is simplified.
