The present invention relates to a compact disc player for an automobile. More specifically, the disc size of two discs (80 mm and 120 mm) of different sizes can be loaded and unloaded by one mechanism. The present invention relates to a compact 80mm / 120mm car compact disc player, regardless of the user's convenience.

Generally, discs used in compact disc players for automobiles are classified into two types of discs, which are 80 mm and 120 mm in size.

A separate compact disc player is provided for reproducing or recording the information recorded on the 80 mm disc and the 120 mm disc.

However, in the related art, compact disc players for automobiles for reproducing and recording information contained in such 80mm and 120mm discs lack mutual compatibility and versatility, so that two types of discs cannot be loaded in a single mechanism.

In other words, a conventional compact disc player for a vehicle for reading information contained in a disc is configured to read only information of a disc having a size of 80 mm or 120 mm.

Therefore, if you have a different size than the compact disc player you have, for example, an 80mm compact disc unit that allows you to read 80mm disc information, you can read 120mm discs of different sizes. There was an uncountable flaw.

In addition, even when the user is provided with a 120 mm compact disc device that reads 120 mm disc information, the information contained in the 80 mm disc could not be read.

As such, there is a problem in that compatibility between the discs is impossible to use by configuring only the information of the disc corresponding to the predetermined size from the initial production line.

Therefore, the user has to select only the disk corresponding to the purchase, thereby relatively limiting the user's choice.

Therefore, the present invention was devised to solve all the problems of the conventional compact disc player for automobiles described above, and 80 mm / 120 mm discs having different types of sizes in the mechanism of one compact disc player for automobiles are also easy. Its purpose is to provide a compact disc player that can be used universally.

In order to achieve the above object, the present invention provides a compact disc player for a vehicle, comprising: a lever selector for rotating a protrusion formed at a rear end when a guide protrusion formed at a tip frame and a guide protrusion formed at the front end interfere with a disc loaded inward; One side of the body, which is installed on the deck frame so as to be pivotable about the wedge, is rotated when a side of the body contacts the protrusion of the lever selection, and an arm lock guide having a locking portion on the other side thereof, and a stopper formed at each end so that the disc abuts. A pair of guide arms R, L, and one guide arm R and an arm lock guide slid along the arc guide of the tension guide spring, and a locking pin formed on the guide arm L according to the size of the disk, Characterized in that the locking portion selectively It is.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a compact disc player for a vehicle according to the present invention will be described in more detail the configuration and effect.

As shown in FIG. 1 of the accompanying drawings, the lever selector 2 is provided to be fixed on the deck frame 1 so as to rotate at a point.

The lever selector 2 is provided with a guide protrusion 21 for sensing the disk D loaded into the deck and a protrusion 22 for driving the arm lock guide 3.

On one side of the lever selector 2, the arm lock guide 3 is fixed to the deck frame 1 so as to be rotatable about white paper 33.

One end of the arm lock guide 3 contacts the protrusion 22 of the lever selector 2, and the other end of the arm lock guide 3 locks the locking pin 31 to the locking pin 5c of the guide arm 5b. 32).

Then, the other end of the arm lock guide 3 is projected by the projection 22 contacting one end of the lever selector 2 which is pivoted by the disk D loaded into the deck frame 1. The locking portions 31 and 32 formed at the other end of the arm lock guide 3 to be rotated as much as possible are configured to fix or release the locking pins 5c of the guide arm 5b.

In addition, the teeth 51 and 52 having the same teeth corresponding to each other are formed on one side of the guide arms R and L 5a and 5b so as to rotate by the same amount. The stopper 7 formed at the other end of the guide arms 5a and 5b has a configuration that slides along the arc-shaped guides 41 and 41 of the clamp 4.

In addition, the one guide arm (5b) and the arm lock guide (3) slid to the outer circumferential surface is connected by a tension spring (6), and the loaded disk (D) is a stopper (7) that is changed in position according to its type, i.e. 120 mm, 80 mm. Close).

According to the present invention configured as described above, the disc abuts on the guide protrusion 21 formed at one end of the lever selector by the disc inserted as shown in FIG. When the disc is pushed, the guide protrusion of the lever selector is driven (shown by the phantom line in FIG. 2), and the protrusion 22 provided at the other end of the lever selector driven by the disc is armed as the lever lever is pivoted. The lock guide is abutted and pushes the arm lock guide.

The other end projection 22 of the lever selector rotated by the disk inserted into the device pushes the arm lock guide 3 to lock the arm lock state (locking pin of the guide arm 5b to the locking part 31). The disk D is stopped by the stopper 7 when the disk 5 is reached in the seating position of the disk while the 5c) is caught. The guide arms 5a and 5b are in an extended state.

At this time, the lever selector rotated by a predetermined angle by the disk is released from the interference between the guide projection of the lever selector and the disk, and is restored to its original state by the elastic restoring force. As the lever selector returns, the arm lock guide also extends the tension spring. While returning to the initial position by the elastic force of (6), the locking piece 5c is caught by the locking portion 32, and the guide arms 5a and 5b are in an unfolded state.

When the disc is unloaded, the guide protrusion of the lever selector is rotated while interfering with the disc. At this time, the arm lock guide is rotated by the protrusion 22, and the locking pin 5c is restrained from the locking portion 32 in this process. . Therefore, the guide arms 5a and 5b are returned to their original positions by the tension spring 6.

On the other hand, during operation of the 80mm disc, as shown in FIG. 3, the disc pushes the guide protrusion of the lever selector as in the operation of the 120mm disc, but the operating distance is shortened by the size difference (120mm and 80mm) of the inserted disc. The guide arm 5a, 5b is locked by not pushing the lock guide.

At this time, when the disk reaches the seating position, the disk is stopped by the stopper 7 at the end of the arm lock guide and stops at the seating position of the disk D.

As described above, the present invention provides a mechanism for driving a guide protrusion and an arm lock guide for detecting a disc loaded on a deck frame so that a disc having a different size can be easily used in the mechanism of a compact disc player for a vehicle. An arm lock guide provided with a lever selector provided with a projection, the one side of the body fixed to the deck frame to be rotatable and abutting the protrusion of the lever selector, and the other side having a locking portion for chucking the guide arm, and one side arc type of clamp 80mm or 120mm discs can also be loaded by one disc device by connecting and guiding the guide arms, which have both ends along the guides, to the outer circumferential surface with tension springs. Information recorded in There are benefits that can record more than I play.
