Abstract

Abstract A cartridge loading apparatus comprises a loading/ejecting and opening/closing mechanism disposed in a housing. The mechanism receives a cartridge which encloses an optical recording disk therein and includes first and second cases from a port formed on the housing in a closed state wherein the first and second cases are in contact with each other, opens the cartridge by separating the first and second cases from each other to expose an area of the disk during the receiving operation, ejects at least part of the cartridge outside of the housing through the port, and closes the cartridge by bringing the first and second cases into contact with each other during the ejecting operation. The central portion of the disk after the opening thereof by the mechanism is clamped between a turntable and clamper, and the exposed area of the disk between the first and second cases is recorded/reproduced by an optical head using a laser beam.

Claim 5
Dependent Claim 29 words
The apparatus according to claim 3, further comprising means for checking that the cartridge is held in said housing and the disk is held by said disk holding means.
Claim 6
Dependent Claim 58 words
The apparatus according to claim 4, wherein said checking means includes an observation window formed in said housing to oppose said first terminal portion of said conveying path when said cartridge handling means is located in said lower position for allowing visual checking of part of the cartridge located in said conveying path of said cartridge handling means.
Claim 7
Dependent Claim 47 words
The apparatus according to claim 3, wherein said disk comprises an optical recording disk, said disk holding means comprises a rotatable turntable, said optical recording disk in the cartridge being placed on said turntable for rotation therewith when said disk handling means is in said lower position.
