PURPOSE:To simplify the constitution and to decrease the number of component parts by making use of a rotary shaft of a guide post which can revolve freely and moves to a prescribed position from a cassette opening part to draw out a tape and therefore loading and unloading a pinch roller to and from a capstan. CONSTITUTION:When a rotary ring 36 is revolved to load a tape, a mobile plate 32 moves via a drive gear 37 and a rack part. Thus a holder plate 24 moves toward D, and a pinch roller 21 is set at a place near a capstan shaft 20. An iron core 41 is energized by a solenoid 40 with a tape drive instruction and presses a projection part 23a. Then a pinch roller arm 23 is revolved clockwise on the basis of the rotary shaft of a guide post 22. Thus the roller 21 is pressed to the capstan 20. |
