Abstract
Abstract A disc cartridge loading apparatus for a recording/reproducing apparatus for loading a disc cartridge housing an information signal recording medium on a cartridge loading unit in the recording/reproducing apparatus is disclosed. The apparatus includes a drive unit supporting base plate having a driving unit for a disc loaded in it and supported flexibly on a stationary substrate by an elastic supporting member (29). The apparatus also includes a cartridge holder for supporting the disc cartridge inserted into a main body of the recording/reproducing apparatus and movably supported by the drive unit supporting base plate (25) by plural supporting members projected on its both sides, and a cartridge holder transporting member movably supported by the stationary substrate for movement in a direction of insertion or ejection into or from a main body of the recording/reproducing apparatus. The cartridge holder transporting member (52) has a cam groove and is moved for loading the disc cartridge. The cam groove is opened at its one end and an engagement between the supporting member and the cam groove is released in a state of completion of loading of the disc cartridge. The disc driving unit for recording and/or reproducing information signals on or from the disc is supported in a floating condition.
