Claims

[Scope of utility model registration request]

A cartridge containing a plurality of disc-shaped information recording media is moved vertically and stopped at a height position corresponding to a position from which a predetermined disc-shaped information recording medium can be pulled out, and the predetermined disc-shaped information recording medium is removed from the cartridge. A disk-shaped information recording medium reproducing device that is played by pulling it out from the cartridge, and in relation to a mechanism that raises and lowers the cartridge in the vertical direction, a force approximately equivalent to the weight of the entire mechanism that moves up and down, including the cartridge, is applied to the entire mechanism. A disk-shaped information recording medium reproducing device comprising a mechanism that acts in a direction to cancel out the weight of the disk.
