Problems solved by technology

[0009] But, because general optical disc loading device all can be provided with 4 photosensors respectively in order to carry out above-mentioned loading operation normally, so, need to use the input port that the photosensor device detects the signal among the 4 input ports of above-mentioned microprocessor 300 properly, Moreover, because the installation of four optical sensors inevitably requires a certain amount of physical installation space, and furthermore, the installation and use of multiple optical sensors will cause an increase in manufacturing costs.

Embodiment Construction

[0030] Embodiments of the disc loading device and method of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] image 3 and Figure 4 It is a partial structural diagram of the disc loading device of the present invention.

[0032] The above optical disk loading device, as mentioned above, is a kind of optical disk loading for selectively loading or loading optical disks with different diameters into or out of the device by means of groove loading, including for selectively loading disks with a diameter of 120mm, for example The groove of any one of the disc compartment 100 in the disc 120 with a diameter of 80 mm and the disc 80 with a diameter of 80 mm. At the same time, the disc mounted on the above groove, such as image 3 As shown, the loading motor 200 is driven to load the outside or load the inside. At this time, in order to be able to detect the size and moving state of the optical disc installed in the abo...

Abstract

The present invention relates to CD loading device and method. The present invention adopts loading furrow, rather than loading tray, in loading CD of 120 mm or 80 mm diameter selectively. The present invention has one light sensor set in side of the CD moving path and the light sensor detects light voltage with different amplitudes and inclination for judging the size and type of the CD. Therefore, the present invention can minimize the CD player. In addition, the present invention provides also CD jamming information to avoid damage of both CD and the player.

Description

(1) Technical field [0001] The present invention relates to an optical disc loading device and method, in particular to an optical disc for selectively loading or unloading optical discs of different sizes, such as 120 mm diameter or 80 mm diameter, into or out of the device by using a slot loading method instead of a tray method Loading device and method. (2) Background technology [0002] figure 1 and figure 2 It is a partial structural diagram of an optical disc loading device using a general groove loading method. The above-mentioned disc loading device includes a disc deck 100 for selectively loading any one of, for example, an optical disc 120 having a diameter of 120 mm and an optical disc 80 having a diameter of 80 mm. [0003] In addition, the above-mentioned optical disc 120 (80), such as figure 2 As shown, the loading motor 200 is driven to load the outside or load the inside. In order to be able to detect the size and moving state of the optical disc mount...
