<p>PURPOSE:To miniaturize a video tape recorder by providing a guide drum shift means which turns in one body with a tape lead-out post with a tape loading action, and at the same time, secures the linear approximation of a guide drum to a tape cassette. CONSTITUTION:A guide drum is turned in one body with a tape lead-out post with a tape loading action. Accordingly a loading ring and a ring mechanism to be provided around a guide drum are made unnecessary, therefore the occupting area of a tape loading mechanism is reduced. In addition, a guide drum shift means is provided to have the linear approximation and separation of the entire guide drum revolving mechanism to and from a tape cassette. This, the large-size parts like a conventional loading ring, etc. is omitted, and the factors which prevent the miniaturization of a video tape recorder is eliminated.</p> |
