Abstract: PURPOSE:To switch assuredly the tape drive without increasing the ejection force of a cassette by making use of a tape drive motor and at the same time switching the reverse reproduction state to the forward reproduction state when the cassette is loaded. CONSTITUTION:When a cassette half A is slightly inserted toward an arrow P, the 1st switch 110 is turned on to revolve a motor 2. Then a PA arm 103 is turned counterclockwise. A loading gear 48 is revolved and engages a gear part 47' of a pulley gear 47, and therefore a projection 51 turns the arm 103. Then a cassette lever 78 is shifted in the same direction by a spring 83 and in response to the shift of a loading lever 71. Thus a cassette A is automatically pulled inside. When the gear 48 is revolved and set at a reproduction mode, a reproduction control lever 125 can be pressed. Thus a reproduction mode sets in. At the beginning of actuation, a slope cam part of a switching slider 31 is pressed through a pressure part 64 of a power slider 57. Thus the reverse reproduction state is switched to a forward reproduction state.
