Disc loading apparatus for a vertical type compact disc player

A disc loading apparatus for a compact disc player, which comprises:

• a door housing mounted to a main body of said disc loading apparatus by hinges, said door housing including a L-shaped sensor pin guide channel disposed in the one side thereof,
• right and left side supporting levers pivotally fixed to lower sides of an interior of said door housing by first pivot pins at lower end portions thereof, respectively, said right and left side supporting levers having an X-shaped cross portion crossed with each other at a middle portion thereof and provided with a pair of supporting pins fixed to an upper end portion thereof, respectively, for passing through a pair of arc channels disposed in the interior of said door housing so as to support a small-sized disc or a large-sized disc and turning along a predetermined angle between a lower position and an upper position of the right and left side supporting levers so as to mate with a center of a turn table of the disc loading apparatus, and
• means for driving for turning said right and left side supporting levers to lower or upper positions of the right and left side supporting lever, said driving means including:
• a bracket vertically, movably mounted to upper and lower guide pins supported on the interior of said door housing at upper and lower vertical guide channels thereof, said bracket provided with a tension coil spring connected to said upper guide pin for maintaining the bracket to be located at an upper position of the door housing,
• an elastic bar fixed to a lower end portion of said bracket at one end thereof and inserted into an elongated hole of the middle portion of said right and left side supporting levers at a bent portion of the other end thereof;
• a slider having a sensor pin guide slot disposed in an upper portion thereof,
• a turning link pivotally fixed to the upper side portion of said main body at an upper portion thereof by a second pivot pin, and pivotally fixed to said slider at a lower portion thereof by a third pivot pin, and
• a sensor lever pivotally fixed to an upper end portion of an upper surface of said bracket by a fourth pivot pin at one end thereof, said sensor lever provided with a sensor pin at the other end thereof wherein the sensor pin moves along
• said L-shaped sensor pin guide channel, whereby the sensor pin detects the insertion of the large-sized disc or the small-sized disc and the large-sized disc and or the small-sized disc are separatively, automatically inserted into the disc loading apparatus and upon opening a door of the door housing, the large-sized disc is automatically lifted from the disc loading apparatus.
