PURPOSE:To reduce the shock of cartridge ejection and to stabilize the ejection by engaging a holder with a slider through a viscous dumper and applying resistance proportional to an ejecting speed to the cartridge. CONSTITUTION:A rack 21 formed on a slider 3 is engaged with a pinion gear 23 engaged with the rotational viscous dumper 22 formed on the holder 2. When the cartridge 1 is loaded and an engaging claw 14 is engaged with an engaging hole 15, the slider 3 tries to jumps out by the elasticity of a spring 13 by disengaging said engagement by driving an electromagnet 20, but the resistance of the dumper 22 is applied to the slider 3 because the slider 3 is engaged with the pinion gear 23 supported by the dumper 22. Thereby, the holder 2 carries the cartridge 1 to the initial position of insertion. Consequently, the cartridge 1 can be correctly ejected from its inserting aperture.
