Document Type and Number:
Japanese Patent JP3092325
Kind Code:
B2
Abstract:
A reel servo device employed in a recording and/or reproducing apparatus employing a tape cassette housing a tape as a recording medium includes an unusual running detection circuit for deciding if the tape housed within the tape cassette loaded on the tape recording and/or reproducing apparatus is wound in a slack winding state on a tape reel. If the tape running state is decided to be an unusual tape running state, tape tension data from the supply side tension arm is differentiated. If the differentiation data is positive indicating an increasing tape tension, the rewind side reel motor is controlled in a direction of slackening tape tension at the rewind tape reel side. Conversely, if the differentiation data is negative indicating an decreasing tape tension, the rewind side reel motor is torqued in a direction of tensioning the tape at the rewind tape reel side.
