<p>PURPOSE:To prevent malfunction surely by designing an operating section not to operate unless a reel shaft of tape taking up side stops, and unless the tape is wound to the terminal. CONSTITUTION:Rotation detecting members b1, b2 are provided for each of a pair of reel shafts a1, a2 that become tape taking-up side and tape supply side alternately. Rotation force of each reel shaft a1, a2 are transmitted to these members b1, b2 through friction mechanisms c1, c2 and energizing force of each rotation detecting member b1, b2 is transmitted to a common operating section (d). A detected member locking mechanism (e) of supply side is coupled to the rotation detecting member of tape supply side b2 and coupling between the rotation detecting member of tape supply side b2 is cut off. It is so designed that when energizing force transmitted from the rotation detecting member of tape taking-up side b1 to the operating section is eliminated, the operating section (d) starts operation.</p> |
