<p>PURPOSE:To prevent the shifting in the width direction of the tape and to obtain the clear picture without interrupting the loading and unloading of the cassette, even not only at the time of the video recording and reproducing but also at the time of the quick feeding search or the rewinding search by contacting the tape guide member with the tape when the pinch roller contacts with a capstan shaft and separating the tape guide member from the tape when the pinch roller is separated. CONSTITUTION:A tape guide member 24 synchronizes with the connecting and separating action of a pinch roller 12 for a capstan shaft 14. Namely, when the pinch roller 12 contacts with a capstan shaft 14, a tape contacting surface 26 of a tape guide member 24 contacts with a tape 4 in a cassette 1, and when the pinch roller 12 is separated from the capstan shaft 14, the tape contacting surface 26 of the tape guide member 24 is also separated from the tape 4 in a cassette 1. Consequently, when the tape 4 is travelled at a high speed, the tape is guided by the tape guide member 24 in the vicinity of the capstan shaft 14 which is a tape driving source, and therefore, the oscillation in the width direction of the tape 4 can be prevented. Thus, the clear picture can be obtained at the time of the quick feeding search or the rewinding search.</p> |
