<p>PURPOSE:To shorten the tape take-up time by allowing the tape to keep the specified speed from the beginning of tape winding till the end of the winding. CONSTITUTION:When a fast-forwarding mode for the tape 13 is selected, for instance, a driving voltage VT required for taking up the tape at the prescribed speed is impressed on the driving motor 18 of the tape take-up side, and a driving voltage VS which is lower (several % to several tens %) than the driving voltage VT also is the voltage in a forward direction, is impressed on the driving motor 16 of the tape supply side which is the tape feeding side. A reverse torque generated in the driving motor 16 is canceled by the driving voltage VS in the forward direction, then the tape is kept in the specified speed from the beginning of tape winding till the end of the winding.</p> |
