Abstract
Abstract A recording/reproducing device comprising a cartridge holder adapted to be moved from an unloaded state to a loaded state by a vertical movement of a roller provided on each side portion of the cartridge holder, and a cam hole having a horizontal portion and a vertical portion respectively for holding the roller in upper and lower positions. The cam hole is formed with a projecting portion at its portion changing from the horizontal portion to the vertical portion so that the roller can get over the projecting portion. It is possible to give the "click" touch to the user at the time of transfer from unloaded to loaded state in the disc cartridge inserting operation.
