Description

  The present invention relates to an optical disc drive apparatus, and more particularly to an optical disc drive apparatus having a disc insertion / ejection mechanism.

  Currently, in an optical disk drive device, the disk is loaded into the core by inserting the disk into the support mechanism of the optical disk drive device by the disk insertion / ejection mechanism. The disc is also ejected by the disc insertion / ejection mechanism.

  The prior art will be described below with reference to the drawings. Please refer to FIG. FIG. 10 is an exploded perspective view showing a conventional disc insertion / ejection mechanism. As shown in FIG. 10, the conventional disk insertion / ejection mechanism includes a support mechanism 91, a core 92, and a slide device 93. A clamping piece 94 is disposed on the slide device 93. A magnetic device 95 is disposed between the holding piece 94 and the slide device 93. The disk held by the magnetic device 95 is loaded into the position of the machine core 92 of the support mechanism 91 by the slide device 93. In the method of holding a disk by magnetic force, the disk is sucked and held by a suction device. When the disc is ejected, a force repelling the magnetic force is required, and a considerable amount of power is consumed. For this reason, a motor having a considerably large output is required, and power is consumed. In addition, since the magnet and the high-power motor are repelled by the suction device, there is a disadvantage that it is costly.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an optical disk drive device having a low-cost disk insertion / ejection mechanism that can save power.

  In order to achieve the above object, the present invention provides an optical disc drive apparatus having a disc insertion / ejection mechanism. An optical disc drive apparatus having a disc insertion / ejection mechanism according to the present invention includes a support mechanism, a core, and a slide device. The support mechanism supports the machine core and the slide device. The support mechanism has a disc insertion slot at the front end. The support mechanism has rails on both inner sides, and the rails have inclined grooves that are inclined upward at the ends. The machine core has a machine core plate, a disk reader disposed on the machine core plate, and a spindle motor. The slide device has a tray, two clamping pieces, and a drive mechanism that moves the tray. The sandwiching piece is provided with a free end portion having a protrusion. When the protrusion moves along the rail and is at the position of the rail, the free end and the tray form a clamping state, and when the protrusion is positioned in the inclined groove at the end of the rail, the free end and the tray are Form an open state.

  Embodiments of the present invention will be described below with reference to the drawings.

  Please refer to FIG. 1 and FIG. FIG. 1 is an exploded perspective view showing an optical disc drive apparatus having a disc insertion / ejection mechanism according to an embodiment of the present invention. FIG. 2 is another exploded perspective view showing an optical disc drive apparatus having a disc insertion / ejection mechanism according to an embodiment of the present invention. As shown in FIGS. 1 and 2, the optical disc drive apparatus having the disc insertion / ejection mechanism of the present invention includes a support mechanism 11, a core 12, and a slide device 13.

  Please refer to FIG. 3 and FIG. FIG. 3 is a perspective view showing an operation in which the tray 131 is positioned near the insertion slot. FIG. 4 is a perspective view showing an operation in which the tray is positioned at the machine core. As shown in FIGS. 3 and 4, the support mechanism 11 of the present invention supports the machine core 12 and the slide device 13. The support mechanism 11 has a disc insertion slot 112 at the front end 111. The support mechanism 11 has rails 113 on both inner sides. The rail 113 has an inclined groove 114 that is inclined upward at the end. As shown in FIG. 2, the rail 113 is recessed into the side walls 115 on both sides of the support mechanism 11, but the rail 113 may protrude from the side walls 115 on both sides of the support mechanism 11 (not shown). ) The support mechanism 11 is a combination of a support mechanism lower part 116 and a support mechanism upper part 117 for convenience in manufacturing and assembly.

  Refer to FIG. 1 again. The machine core 12 of the present invention has a machine core plate 121, a disk reading device 122 and a spindle motor 123 arranged on the machine core plate 121. The machine core 12 is fixed in the support mechanism 11 by the machine core plate 121. The disk reader 122 includes a laser reader 1221, a motor 1222, a transmission mechanism 1223, and a slide bar 1224. The transmission mechanism 1223 transmits the power of the motor 1222 to the laser reader 1221 to move the laser reader 1221 along the slide bar 1224. The spindle motor 123 rotates the disk 14.

Reference is made to FIGS. FIG. 5 is a plan view of FIG. 6 is a cross-sectional view of the XX plane of FIG. FIG. 7 is a bottom view of FIG. FIG. 8 is a cross-sectional view showing an operation in which the tray is positioned near the insertion slot. FIG. 9 is a cross-sectional view showing the operation of the tray positioned at the machine core.
As shown in FIGS. 1 to 9, the slide device 13 of the present invention has a tray 131, two clamping pieces 132, and a drive mechanism 133 that moves the tray 131. The sandwiching piece 132 has, at one end, a pivot end 134 that pivots on the tray 131 and swings.
