Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a disc insertion device for a small record player, a compact disc player, etc., and particularly relates to a disc insertion device suitable for reducing the overall size of the case.

[Background of the invention]

Conventionally, by making it possible to take out the turntable to the front of the record player without opening the cover of the record player, there was a record player that allowed items to be placed on the cover, such as the No. 22307 (this publication is disclosed).

This record player includes a first turntable, a second turntable for mounting a disc that is removably attached to the first turntable, and an original second turntable that is connected to the player from the first turntable. However, this record player has a complicated structure, takes time and effort to manufacture, and is not suitable for miniaturization.

[Purpose of the invention]

An object of the present invention is to eliminate the drawbacks of the prior art described above, to have a simple structure, and to be suitable for miniaturization. To provide a disc insertion device capable of inserting or ejecting a disc from the front surface of a case. [Summary of the Invention] The present invention is characterized by supporting a turntable on a movable base and extending in the direction of movement of the movable base. A rack is provided, and a fixed shaft is provided at one corner of the front part of the case, g. The fixed shaft supports a lever to which a fan-shaped gear that meshes with the rack is fixed, so that the structure can be made simple and compact. The present invention is further explained in detail by providing a disc insertion device with good operability. [Practice of the Invention] The present invention will be explained in detail below with reference to examples.

FIG. 1 is a partially cutaway plan view of an embodiment of the present invention, FIG. 2 is a cross-sectional view along the line taken along the line shown in FIG. 1, and FIG. 3 is a partially cutaway plan view when the turntable is pulled out.

In FIGS. 1 and 2, l indicates a compact disc case, and a pair of frames 4a and 4b extending rearward from the front surface of the original case l are placed on the bottom surface of the cough case 1 at a predetermined interval. It is fixed in parallel and also %
Between the pair of frames 4a and 4b, two pairs of rows 23m, 3b and 3c, 3d are installed at the front and center portions, respectively.

The movable base 2 placed on the rollers 3C and 3d has a row F3e13f protruding left and right at its rear part, and the rollers 3e and 3f are located under the projecting parts of the frames 4a and 4b, respectively. Therefore, the original movable base 2 can be moved in the front and back direction with respect to the case 1 by the rollers 3a to 3f, and the frame 4 can be moved in the vertical direction.

The overhanging portion of 4b prevents it from coming off.

A rack 5 is fixed to the upper surface of the movable base 2, passing through the center of the case 1 and extending parallel to the frame, and a turntable direct drive motor 6 is fixed on the rack 5. ◎Also, a turntable 7 is supported on the rotating shaft of the eye motor 6.

On the other hand, a fixed shaft 8 is installed at the right corner of the front surface of the case 1, and a boss portion 9a of a lever 9 is inserted into the fixed shaft 8. Therefore, the lever 9 is rotatable around the fixed shaft 8. A fan-shaped gear 9b with a center angle of approximately 90' is fixed to the lever 9 so as to rotate together with the lever 9. , the gear 9b and the rack 5 mesh with each other.

Next, the operation of this embodiment will be explained.

Now, in FIG. 1, when the handle 9c of the lever 9 is pulled in the direction of the arrow X, the gear 9b also rotates in the same direction. Then, the rack 5 meshing with the original gear 9b receives a forward force, and the movable base 2 moves forward. Therefore, the turntable 7 placed on the cough moving base moves forward as shown in FIG. At this time, the movable base 2 is initially supported by the rows 93c, 3d, 3e, and 3ft, and after the movable base comes near the front of the case 1, it is supported by the rollers 3a, 3b, 3e, and 3f.

Move smoothly on the bottom plate of case 1. When the lever 9 is rotated to a position where it is in line with the side surface of the case 1, the lever 9 stops rotating and the turntable 7 is pushed forward as far as possible.

When the turntable 7 is extended to the position shown in Figure 3, the disc is placed on the turntable.Then, when the lever 9 is rotated in the direction of the arrow Y.

The operation opposite to the above is performed, and the turntable 7 is housed in the case 1, returning to the state shown in Figure 1. Therefore, the disc is inserted into the case 1.As described above, the present embodiment According to , despite the simple configuration, it is easy to insert and remove discs.

〔Effect of the invention〕

According to the present invention, the following various effects can be achieved. (11) With a simple configuration, the turntable can be pulled out to the front of the case and can be housed inside the case, reducing manufacturing time. It does not require much effort and can be formed compactly.Furthermore, the device can be manufactured at low cost.

(2) Since other sets etc. can be stacked on top of the case, space can be saved. (3) The disc insertion device of the present invention can be made compact and lightweight, so it can be used as a small and portable device. Suitable for record players or small compact disc players.

(4) Since the movable base is pulled out and stored from the case by rotating the handle of the lever, the operating force is approximately half that of the method of directly pulling out the movable part, which improves operability. The vibration of the set during operation is reduced.
