Claims

[Scope of utility model registration request]

a mode switching slider having a second cam near the eject mode position in addition to a set of first cams for constant speed and high speed disposed on the left and right sides of the stop mode position;
a brake release slider that engages with the second cam and moves forward against the urging means to release the reel platform brake as the mode switching slider moves; and a mode switching slider that engages with the second cam. a set-up member for moving the brake release slider forward against the biasing means by movement of the cassette holster with no cassette inserted;
When the mode switching slider is mounted, the mode switching slider waits at a loading/unloading mode position adjacent to the eject mode.
