Description

[Detailed Description of the Invention] The present invention is a disk player in which the player body that drives the set disk can be pulled out from the casing, and in particular, the magnet for the disk clamp is rotatably suspended above the disk when stored. The present invention relates to a disc player in which the player body has a holder that is lowered and retracted from the disc when pulled out.

This type of disc player is very suitable for use because the player body that drives the set disc can be pulled out from the casing to replace the disc, but the disc on the player body that is pulled out rotates. It is inconvenient to carry out the exchange if the

Conventionally, a brake pad 20 is pressed by a solenoid 16 and a lever 18 on a turntable 14 driven by a motor 10 to rotate a disk 12, as shown in FIG. 1, and a disk clamp is used as shown in FIG. By pressing the brake pad 20 with the solenoid 16 and lever 18 on the side of the disc clamp magnet 22, or by driving the lever 18 with A as the fulcrum as shown in FIG. A brake pad 20 is pressed against the upper surface to stop the rotation of the disk 12 when the player main body 24 is pulled out.

However, as mentioned above, conventionally, disk 1
Since a drive source such as a solenoid 16 is required to stop the rotation of the disc player, there is a problem in that the manufacturing cost of the disc player increases.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a disk player that can reduce manufacturing costs.

In order to achieve the above object, the present invention is such that the player main body that drives the set disc can be pulled out from the casing, and the player main body rotatably supports a magnet for disc clamping at the front end of the player main body so as to hold the disc when stored. It has a holder that includes an elevating mechanism that lowers the player and retracts it from the disk when it is pulled out, and a brake pad that is placed above the magnet. The present invention is characterized by a cam mechanism that lowers the tip of the holder until the brake pad is pressed by the magnet while the player body is being pulled out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a disc player according to the present invention will be described below with reference to the drawings.

FIG. 4 shows the appearance of the disc player of this embodiment, with the player body 24 in the stored state and the front panel 28 of the casing 26 showing the player body 24.
Only the door 30 rotatably attached to the front of the screen is visible.

FIG. 5 shows a state in which the player body 24 is pulled out, and guide rails 32 for pulling out the player body 24 are provided on both sides of the player body 24.
Further, the holder 34 supporting the disk clamp magnet 22 at its tip is retracted upward from the set disk 12.

In FIG. 6, the guide rail 32 is guided by rollers 36 provided inside the casing 26, so that the player main body 24 is moved inside the casing 26.
After that, the disc 12 is rotated on the turntable 14. The disk clamp magnet 22 is rotatably suspended from the tip of the holder 34, and at this time, the holder 34 lowers its tip using a lifting mechanism 38, which will be described later, to lower the disk clamp magnet 22 onto the disk 12. let Further, the tip of the holder 34 can be pulled up by the elevating mechanism 38 to retract the disk clamping magnet 22 upward from the disk 12.

In FIG. 7, the elevating mechanism 3 of the holder 34 is
Reference numeral 8 denotes a rotating cam 42 in which a cam groove 40 is formed, and a lever plate 4 rotatably supported by a pin 44.
A pin 48 inserted into the cam groove 40 is erected at one end of the lever plate 46, and the other end is connected by a pin 52 to the base of the holder 34 with the pin 50 as a fulcrum. ing.

Further, the tip of the holder 34 is formed into a U-shaped cross section with the tip bent inward, and a disk clamp magnet 2 formed in a disk shape is placed inside the holder 34.
The disk clamp magnet 22 is rotatably suspended from the tip of the holder 34 into which the top of the disk clamp 22 is inserted. A rubber brake pad 20 is attached to the inner surface of the front end of the holder 34 above the disk clamp magnet 22.

Here, since the cam groove 40 is formed as shown in the figure, when the rotary cam 42 is rotated in one direction, the height of the tip of the holder 34 changes as shown in FIG.
At first, the tip of the holder 34 is at a height where the brake pad 20 is not in contact with the top surface of the disk clamp magnet 22, but then it descends once and presses the brake pad 20 against the top surface of the disk clamp magnet 22, and then moves upward. evacuate.

The rotating cam 42 is driven by a motor 58 via a gear 54 and a pulley 56, as shown in FIG.

In this embodiment, the rotary cam 42 is also used to move the player body 24 when it is stored or pulled out, and therefore the rotary cam 42, gear 54, and pulley 5
6. The motor 58 is placed on the same chassis 60 of the player main body 24, and the rotating cam 42 is also used as a pulley and is rotated to generate the first
As shown in FIG. 0, the casing 26 is stretched between the front and rear chassis, and the intermediate portion thereof is movable along a wire 66 wound around the rotating cam 42. Therefore, the player main body 24 has a rotary cam 42.
can be moved into or out of the casing 26 by being rotated.

A preferred embodiment of the disk player according to the present invention has the above configuration, and its operation will be explained below.

As shown in FIG. 5, the player body 24 is pulled out and the disc 12 is set with the holder 34 retracted upward.

Thereafter, when the rotating cam 42 is rotated in one direction, the player body 24 moves toward the inside of the casing 26, and at this time, the height of the tip of the holder 34 changes in the opposite direction as shown in FIG. 8, and the holder 34 descends. Then attach the brake pad 20 to the disk clamp magnet 22.
Press it against the top surface of the holder and then retract it slightly so that the two do not come into contact with each other.

In this manner, after the player body 24 is housed as shown in FIG. 4, the disc 12 is played back.

When the above-mentioned playback is completed and the disk 12 is removed or replaced, the rotary cam 42 is rotated in the opposite direction and the height of the tip of the holder 34 changes as shown in FIG. 8, and the holder 34 is temporarily removed. It descends and presses the brake pad 20 against the upper surface of the disk clamp magnet 22 to stop the rotation of the disk 12, and then retreats upward.

As explained above, according to this embodiment, the rotation of the disk 12 can be stopped when the player main body 24 is pulled out with a simple configuration without requiring a power source such as the solenoid 16 as in the conventional case. Therefore, it is possible to reduce the manufacturing cost of the device.

Further, according to this embodiment, when the brake pad 20 is pressed by the disc clamp magnet 22, the contact pressure between the disc clamp magnet 22 and the turntable 14 increases, so that the two do not slide. This makes it possible to reliably stop the rotation of the disk 12.

Furthermore, since the holder 34 operates as shown in FIG. 8, the height of the tip of the holder 34 can be lowered when the player main body 24 passes through the insertion opening, thereby making the device thinner and more compact. This makes it possible to achieve

As explained above, according to the present invention, it is possible to construct a disk player at low cost.
