<p>PURPOSE:To prevent such a hindrance as a running failure, etc., to be caused by a tape sag by constituting this cassette tape deck so that the time extending from the rotation stop of a reel axis to the tape end detection can be set long. CONSTITUTION:A pickup lever 54 is brought to fist stage centering by an outer cam of a detection gear 49 in a state that it is stopped by a stop of a reel axis 3, and thereafter, brought to final stage centering and executes a tape end detection, and a switching operation of a switching lever. Accordingly, the time extending from the rotation stop of the reel axis 3 to the tape end detection becomes longer, that is, according to the constitution shown in this figure, unless the gear 49 is rotated by >=360 deg., the tape end detection cannot be executed. In such a way, in the case when a sag is generated in the tape, the tape end detection is executed in a state that the tape is wound completely to one reel axis side, and an erroneous detection, a malfunction of switching, etc. can be prevented.</p> |
