Abstract
In the loading of a disc in a slot-in type of disc apparatus, time lag occurs at the time of shift from an operation that manually inserts the disc to an operation that automatically swallows the disc. In order to solve this problem, a switch for detecting the position of a disc at the beginning of insertion thereof and a switch for detecting a position where the loading of the disc has been completed are provided respectively. The modification of control is made so that the disc support arm is driven with a weak electric power from the beginning of the insertion of the disc, and an error caused by time-out is further detected. If the error has been detected, the disc is ejected.
