<p>PURPOSE:To prevent slant of a tape during the movement of a cassette loading stand, by fitting a ring-shaped latching member with a projection elastically with a plate spring around through-hole a reel stand of provided at the bottom plate of a cassette loading stand adjacent to the reel stand. CONSTITUTION:Around a reel stand through-hole 2 provided at a bottom plate 1 of a cassette loading stand adjacent to a reel stand, a ring-shaped latching member 3 is fitted with a screw 6 via a plate spring 5 elastically. Two latch projections 4 and 4' are fitted to the member 3 at a right angle. When a cassette 8 is inserted along the cassette loading stand bottom plate 1 toward the arrow, A radius part of the tip of the cassette 8 is progressed while pushing the projections 4 and 4' downward. When the part is progressed to the specified position, a reel stand insertion hole of the cassette comes over the projections 4 and 4' and the projections 4 and 4' are restored upward with the force of the spring 5 to block the rotation of the reel in the cassette. When the cassette is unloaded, the projections 4 and 4' are falled down again. Thus, slant of the tape due to unnecessary rotation of reel can be prevented.</p> |
