<p>PURPOSE:To omit a loading motor and, at the same time, to attain an automatic lading action of a tape by using a lading elastic member which winds a tape around a guide drum, and an unloading elastic member which collects the tape from the guide drum. CONSTITUTION:The elastic force of both a loading and unloading elastic members are stored in a manual operation mode where a cassette holder is loaded to a VTR (video tape recorder) main body. The elastic force of the loading elastic member is released as soon as the cassette holder hooked to the VTR main body. A tape lead-out post is turned by a prescribed angle around a guide drum by the lading elastic member. Thus a tape is wound round the guide drum. While the elastic force of the unloading elastic member is released by a cassette unloading command. Then, the tape lead-out post is set at a tape cassette opening part. At the same time, the tape is also reset to a tape cassette. Finally the cassette holder hooked to the VTR main body is released.</p> |
