The present invention relates to a disc guide and a protection device of a compact disc player (CDP), in particular to improve the door opening and closing structure and the disc guide structure to be suitable for compact disc protection.

In the conventional disc guide and protection device, as shown in Fig. 11, the disc spindle motor and the disc or the disk opening and closing in the recess 2 'at the mouth side of the case where the pick-up or door opening and closing oath is installed. The door 4 'having the magnet 43' and the guide guide 44 'for the disk support on both sides thereof has a hinge opening / closing method using shaft pins on both side walls of the recess 2'. It is installed.

Therefore, when the door opening button is pressed, the upper part of the door 4 'is rotated around the hinge parts of the lower both sides by the ejecting device to protrude downward, so that the disk 17' is disposed on the guide protrusions 44 'on both sides of the lower rear part. ), And then insert the original position into the recess, press the play button, the disk 17 'is raised and rotated between the clamping mark net 43' and the turning hole of the spindle motor 3 'end, and the The pickup is vertically transported from the rear to sense and transmit the signal recorded on the disk.

By the way, since the disc protection support device depends only on the guide protrusions 44 'on both sides of the rear side under the rear of the door, the disc has been improved when the disc is raised and the operation mist door 4' is opened during the play operation. There was a problem that the disc of the case is damaged by falling to the bottom of the concave, and the case where the other parts collided with it are also damaged.

Therefore, the present invention, in order to solve the conventional problems as described above, by installing a shaft forward and backward by a separate drive gear on both sides of the recess, and using a guide hinge to be penetrated through the sliding material between both shafts disc The door is fixedly inserted at the front end of both shafts while the door is fixedly installed, and the door is moved forward and backward by the two shafts, so that the disk is released from the recess along the rotation or the door while being located in the housing. In order to protect the disk completely and extend its lifespan, and to protect the peripherals, the following description will be given in detail according to the attached drawings.

In other words, the disc 14 is formed in the recess 2 of the compact disc player having the spindle motor 3 having the pivoting hole 31 and the door opening / closing stop sensor 15, 16 at the central portion. In the combined installation of the door 4 having the clamping magnet 430 and the disk protection device, as shown in FIG. 10, the sliding coupling portion is provided at the front of the rack 52 and the locking jaw 53 at the bottom of the rear end of the center. After forming the shaft 5 having a predetermined length with 51, it is inserted into each of the insertion holes 21 on both sides of the central portion of the recess 2 as shown in FIGS. In the rack 52 of both shafts 5 located thereon, the pinion gears 12 for forward and backward operation, which are simultaneously operated by the connecting bars 121, are engaged with each other, as shown in FIG. ) Rotor on the side of drive motor (13) which is operated reversely by separate door open / close switch 131 was combined.

In addition, a guide hinge 8 having a shaft pin 82 on one side of the sliding coupling portion 51 of the shaft 5 on both sides uses a central shaft hole 81 for symmetry. Loose fit in shape.

In addition, as shown in Figure 6, the inside of the disk insertion groove 91 is opened in the upper, the recessed groove 92 extending in the vertical direction to the front and rear walls, respectively, and the recessed portion of the panel on one side of the rear side ( The disc housing 9 provided with the insertion stop motion sensor 15 and the joining protrusion 94 provided in 2) is connected to the side guide hinges 8 by using the plate engaging grooves 93 on both side walls thereof. Coupling was installed in the shaft pin 82 to rotate.

In addition, as shown in FIGS. 3 and 5, the bracket 95 of the rear center lower portion of the disc housing 9 installed to rotate between the guide hinges 8 on both sides is provided with a separation preventing jaw 111 at the rear end. A disk having a pin 11 is provided with a front end of a lever 11 of a predetermined length, which is provided and slidingly engaged in the lower insertion hole 22 of the recess 2, and is pushed forward by the step 53 of the shaft 5. The upper part of the housing 9 rotates in a slightly rectangular shape so that the disk can be easily inserted or removed in the rear by pulling the lower part of the housing 9.

At this time, in the state in which the lever 11 is protruded to the maximum, the lower jaw 111 of the lower insertion hole 22 contacts the release stop operation sensor 16 inside the lower insertion hole 22 and the driving motor 13. ) To stop the operation of the disk housing (9) in the bottom and both side walls of the disk insertion groove (91) attached to the buffer member (10) to be installed to protect the disk (17) therein. .

And, Figure 7 shows the door 4 according to the present invention, the disk flapping magnet 43 on the rear center portion, and the upper and lower sides by pushing the disk housing 9 during the door closing action recesses (2) A push rod 41 for precisely inserting and engaging the inside and outside of the actuator is formed, and the front end portion of the slide coupling portion 51 of the shaft 5 is firmly inserted into the coupling hole 42 at both sides of the central portion.

Looking at the operating state of the present invention configured as described above are as follows.

First, the door opening button on one side of the panel is pressed, and the drive motor 13 operates to rotate the pinion gear 12 in the forward direction, so that the rack 5 engaged with the shaft 5 moves forward. The front part 2 protrudes forward from the insertion hole 21 at both sides, and the forward door 4 of the front end is transported forward in a horizontal state.

At this time, the shaft (5) pushes the guide hinge 8 coupled to the sliding coupling portion 51 during the forward movement together as the step 53, and the forward operation, so that the disc housing coupled to the shaft pin 82 ( 9) is driven forward by leading the lever 11 pin-bonded to the rear lower end, the jaw 111 of the lever 11 Maran is in contact with the separation stop sensor 16 to stop the operation of the drive motor 13 shaft The forward projection of (5) is stopped and the tape housing 9 is positioned with its upper opening slightly inclined outwardly by the lever 11, so that the disk 17 can be easily inserted therein. It can be separated.

Then, when the door closing button is pressed, the drive motor 13 is operated in the opposite direction of the opening, so that the rack 52 is reversed by the pinion gear 12 and the shaft 5 pulls the door 4 into the insertion hole. The inner wall of the panel is inserted through the panel 21, and the tape housing 9 is inserted into the recess 2 when the tape housing 9 is pushed and joined together as the pusher 41 of the rear upper and lower sides. (9) When the protrusion 94 on the rear surface comes into contact with the insertion stop sensor 15 and the operation of the driving motor 13 is stopped, the closing of the door 4 is completed.

Thereafter, the magnet 43 at the rear of the door 4 and the pivoting hole 31 at the tip of the spindle motor 3 are inserted into the front and rear concave grooves 92 of the disk housing 9 so that the internal disk 17 ) Is clamped to allow rotation.

The present invention is constructed and operated as described above, the door 4 is fixedly installed at the tip of the shaft (5) which is moved back and forth through the two insertion holes 21 of the recessed portion 2 by a separate operating device Therefore, the opening and closing operation is changed from the conventional rotation opening and closing method, and at the same time, a separate disk housing 9 is installed on the rear shaft by using the guide hinge 8, so that the disk is always inside As it is rotated by the clamping magnet 43 of the upper door shaft located at the rotational axis of the spindle motor, the door 4 is opened during the rotation of the disk, and the disk is irrespective of the buffer member 10 inside the insertion groove 91. It is supported by) to prevent damage, of course, can be used semi-permanently, and in addition to the complete protection of the peripheral device, at the same time, there is an exceptional effect that can solve the conventional problems.
