<p>PURPOSE:To facilitate the recognition of a tape travel state and to save electric power by transmitting the rotation of a reel base and the like to a rotational display board provided in a cassette holder so as to rotate the rotational display board and obtaining rotational power from the existed rotational part of the reel base and the like. CONSTITUTION:The rotational display board 71 is freely and turnably disposed in the cassette holder 36 and a gear 72 is disposed on a same axis under the rotational display board 71. The rotational power of the gear 72 is transmitted from a gear 59A through the gears 72 and 73. When the cassette holder 36 is closed and a winding reel base 44 rotates, the rotational power is transmitted to the gear 72 through a pulley 44A, a belt 67, a pulley 65C, gears 65B and 66B, a rotational axis 59 and the gears 59A, 73 and 74, and the rotational display board 71 is rotated. Thus, the tape travel state can easily be recognized and electric power can be saved.</p> |
