ABSTRACT:
A disc device has a movable mechanism used for moving a carriage carrying a disc so that the carriage either projects from an apparatus or is inserted into the apparatus. The disc carried by the carriage is exposed for an operator to handle the disc when the carriage projects from the apparatus. The disc carried by the carriage is contained in the apparatus after the carriage has been inserted into the apparatus. A rotating unit rotates the disc carried by the carriage and an accessing unit accesses the disc carried by the carriage. The disc device is incorporated into the apparatus. A locking mechanism locks the carriage in the apparatus, and a releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The releasing unit causes the rotating unit to stop rotating of the disc and also causes the accessing unit to stop accessing the disc, prior to each time the releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The locking mechanism is contained in the carriage.
