Problems solved by technology

[0003] This type of device has the disadvantage that in playback mode the user can inadvertently move the extended carriage in the direction of the retracted position, so that if the corresponding disc holding position provided with the disc is arranged for Returning to the exact position of the free position required for the disc being played, or the disc holder being at an angular position that does not correspond to the retracted position, then there will be a gap between the disc being played and the newly inserted disc or disc holder.

Embodiment Construction

[0020] Figure 1 schematically shows a CD changer 1 according to the invention with the carriage 2 in the retracted position. A substantially circular disk holder 3 is rotatably arranged on the carriage 2 . Five optical recording media 4 , also referred to below as discs 4 , are accommodated in disc holding positions 5 of the disc holder 3 . In this illustration, the disk holding location 5 is covered by the disk 4 . The disc holder 3 is commanded to rotate so that each disc 4 can be placed in each angular position. The disc playback unit 6 is schematically shown in the figure. It is located in the lower right corner of Figure 1. The holding arm 7 is used to hold the disk 4, and the holding arm is held by a drive unit from the other side which is not visible in the figure. Further details will be known to those skilled in the art, so descriptions thereof are omitted.

[0021] Furthermore, the carriage kinematic mechanism 8 is schematically shown in the figure. Since it is...

Abstract

The present invention relates to a CD changer of the 'carousel type', in which three or five optical recording media, referred to below as disk, are arranged on a rotatable disk holder, the carousel. It has a drawer (2) which can be moved between a retracted and an extended position by a drawer movement mechanism (8). The object of the invention is to propose a solution which improves the functionality of the CD changer. It is proposed in the invention that the drawer has a stop (15, 25) which, in the extended position, bears against a pin (11, 21) of the drawer movement mechanism (8), and which, when force acts on the drawer (2), exerts on the drawer movement mechanism a force which is directed in the radial direction of said mechanism.

Description

technical field [0001] The present invention relates to a "carousel type" CD changer in which three or five optical recording media, hereinafter referred to as discs, are arranged on a rotatable disc holder, a carousel. Two, four, six or more trays can be set here. Background technique [0002] The disc holder is arranged on a carriage arranged in such a way that it is movable between a retracted position where it is retracted into the CD changer and an extended position. In the extended position, an operator can insert, replace or remove individual discs at the freely accessible disc holding position. If a disk needs to be inserted, replaced or removed at a non-freely accessible disk holding position, the disk holder can be rotated in response to a command until it is rotated to a corresponding freely accessible disk holding position. The CD changer also includes a disc player unit that interacts with one of the disc holding positions when the carriage is in the retracted...
