Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc loading device for loading / unloading a disc into / from a device body.

Conventional technology Conventionally, the disk is moved horizontally and mounted on the device body.
A disc loading device for ejecting is used. FIG. 3 is a perspective view showing an outline of an apparatus using such a disc loading apparatus, and FIGS. 4 and 5 are movable members 11 of the apparatus.
The support structure of is shown.

A pair of guide members 12 are provided at the bottom of the movable member 11, and the first guide members 12 are provided above and below the guide member 12.
The pedestal 1 provided inside the main body 21 by the roller 13 of
The second roller 15 is floated and held above the No. 4 and is positioned in the left-right direction by a second roller 15 that engages with a groove provided on the lower surface of the guide member 12.

Reference numeral 16 is a support shaft for rotatably supporting the first roller 13, and 17 is a support plate to which the support shaft 16 is attached.
Is attached to the pedestal 14. Reference numeral 19 is a support shaft for rotatably supporting the second roller 15 and is attached to the fourteenth. Reference numeral 20 is a screw for attaching the guide member 12 to the movable member 11.

Problems to be Solved by the Invention In the conventional device configured as described above, the movable member 11
Since the rollers 13 and 15 rotate when is moved horizontally, it is possible to operate the movable member 11 with an extremely light load. However, since many parts for supporting the movable member 11 are required and assembly is troublesome, the cost is low. It had the problem of being expensive.

The present invention solves the above conventional problems.
To provide a disc loading device capable of smoothly performing a horizontal movement of a disc with a simple structure.

Means for Solving the Problems In order to solve the above problems, the disk loading device of the present invention is a guide groove having a cross-sectional shape formed by a pair of substantially V-shaped grooves or protrusions that oppose both left and right side surfaces. A movable member provided with, a rotary member that engages with a guide groove provided in the movable member, and a support shaft that rotatably supports the rotary member.

Operation The present invention makes it possible to smoothly move the movable member horizontally with a small number of parts.

Embodiment A disk loading device according to an embodiment of the present invention will be described below with reference to the drawings. 1 and 2 are an exploded perspective view and a sectional view of an essential part showing an embodiment of the present invention, in which 1 is a movable member and 2 is a guide member attached to both left and right side surfaces of the movable member. , A pair of upper and lower grooves having a substantially V-shaped cross section are formed so as to face each other. Reference numerals 3 and 4 denote rotating bodies having a substantially V-shaped cross-sectional shape that engage with the substantially V-shaped groove portion of the guide member 2. 5 and 6 are the rotating bodies 3 and 4
A support shaft for rotatably holding
A support plate 6 is attached to a pedestal 10 provided inside the main body with screws 9. One of the rotating bodies 3 is rotatably engaged with and supported by the supporting shaft 5 with high precision, and the axial gap between the rotating body 3 and the supporting shaft 5 is reduced to reduce the axial movement as much as possible. The other rotating body 4 is formed shorter than the support shaft 6 so as to be axially movable on the support shaft 6. Since it is formed in this manner, even if a dimensional error of the movable member 1 or a dimensional change due to a temperature change occurs, a smooth operation is performed without fluctuation in the operating load.

As described above, according to the present embodiment, a pair of guide members formed in a substantially V-shaped cross-sectional shape facing both side surfaces of the movable member, and a substantially V-shaped member engaging with the groove portion of the guide member. By providing a rotating body having a cross-sectional shape and a support shaft that rotatably holds the rotating body, the rotating body rotates, so that the movable member can be operated with an extremely light load.

In the above embodiment, the guide member 2 has a cross-sectional shape of approximately V
Although the V-shaped concave portions are opposed to each other and the cross-sectional shapes of the rotating bodies 5 and 6 are substantially V-shaped convex shapes, the guide member 2 has a cross-sectional shape in which substantially V-shaped convex portions are opposed to each other. The rotating bodies 5 and 6 may be formed in a substantially V-shaped concave shape in cross section.

EFFECTS OF THE INVENTION As described above, the present invention provides a movable member having guide grooves having a cross-sectional shape formed by a pair of opposed substantially V-shaped concave portions or convex portions on the left and right side surfaces, and the movable member. And at least two on one side surface of the movable member and at least one on the other side surface of the movable member, which has a substantially V-shaped convex or concave cross-sectional shape. By providing a support shaft that rotatably holds the rotating body, a smooth horizontal operation of the movable member can be realized with a small number of parts.
