PURPOSE:To constitute a shutter opening and closing means in a small space by engaging the engaging part provided on a cam means with the shutter of a chucked cassette, and opening and closing the shutter by interlocking to the movement of the cassette. CONSTITUTION:Continuous line and chain line show a chucking position (discharging position) and a two-dot long and two short dashes line shows the loading position drawing in a cassette 10. The cam means 35C, 71, 73 varying the movement of the chucked cassette 10 in the shutter opening and closing directions from the left to the right of the cassette 10 are provided, the claw 72 of the fitting projection fitting to the recessed part 18 of a shutter 17 is provided at the moving part in the shutter opening and closing directions of his cam means and an opening part 16 is made to open and close by moving the shutter 17 by linking to the pushing and discharging of the cassette 10. The shutter is thus made to open and close mechanically and surely without relying on a spring energizing force by opening and closing the shutter 17 by linking to the movement of the cassette 10 by engaging the engaging part 72 provided on the cam means with the shutter 17 of the chucked cassette 10.
