Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a disc transfer device provided in a player of a disc-shaped recording medium (hereinafter, abbreviated as a disc).

(Prior Art) In order to avoid deformation and dust adhesion due to rolling contact of the disc surface during transportation, the disc peripheral edges should be close to each other,
A disk transporting device, which is sandwiched by a pair of rollers rotatably supported so as to perform a transporting operation, is disclosed in JP-A-60-
It is known as 138766 and JP-A-62-229567.

(Problems to be Solved by the Invention) In the case of the large-diameter disk 1 shown in the schematic front view of FIG. 10, the above-mentioned conventional apparatus can hold the peripheral portion by the roller 2 which can move up and down and the roller 3 which cannot move. In the case of a small-diameter disk 4 shown in a schematic front view in FIG. 11, both side portions 2a, 3a of the upper and lower rollers 2, 3 come into contact with each other,
The disk 4 cannot be held by these rollers 2 and 3.

This invention solves the above-mentioned disadvantage of the conventional device in which a disc cannot be conveyed except for discs having an outside diameter within a specific range, and a disc conveyer capable of surely conveying discs having various outside diameters is provided. The purpose is to provide.

(Means for Solving the Problems) A structure of the present invention for achieving the above object is a roller base having a central portion formed low and gradually increasing in the left and right side directions, and a central portion having a small diameter. Formed in
The upper edge of the roller base and the lower edge of the roller are placed in front of each other by sandwiching the peripheral edge of the disk with a roller that is gradually increased in diameter in both side directions and is supported by a roller that is capable of approaching and separating from the roller base. In order to be able to approach the shapes that intersect each other visually,
The shaft support position is set.

Further, in a disc transfer device in which the central portion is formed to have a small diameter, the diameter is gradually increased in the direction of both sides, and the peripheral portions of the disc are held by upper and lower rollers that are pivotally supported so that they can move toward and away from each other. These rollers are pivotally supported so that the lower edges of the rollers and the upper edges of the lower rollers can be brought close to each other so as to intersect each other in a front view.

(Operation) A roller base whose central portion is formed to be low and whose height is gradually increased in the left and right side portions, and a roller whose central portion is small in diameter and whose diameters are gradually increased in both lateral directions are used to increase the upper edge of the roller base and the roller. Since the lower edges can be brought close to each other so that they can cross each other, the peripheral portion of the small-diameter disk can be reliably held by the narrowed upper edges and the lower edges.

The lower edge of the upper roller and the upper edge of the lower roller intersect with the upper and lower rollers that are formed with a small diameter in the central portion and gradually increase in diameter in the direction of both sides so as to be freely contactable and separable. Since the shaft is supported so that it can approach the shape, in the case of a small-diameter disc, the upper and lower rollers come closer to each other and the width of the contour becomes narrower. The peripheral edge of the is securely clamped.

As described above, by using the roller or the combination of the roller base and the roller, it becomes possible to reliably hold and carry disks of various sizes.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings.

The transport surface 18 and the roller 1 without coming into contact with the roller 1.
The above-mentioned members are set so that the lower edge near the center of 1 forms a rhombus-shaped gap in front view into which the front end portions of the disks 1 to 4 can be inserted.

The roller 11 is rotated in a carry-in direction or a discharge direction by a drive gear mechanism 23 and a loading motor (not shown) that drives the drive gear mechanism 23.

In the illustrated drive gear mechanism 23, a gear 24 fixed to the shaft 12 and a pinion 25 fixed to the loading motor shaft are interlocked by a pinion 26 and a gear 27, and a pinion 28 and a gear 29, which are integrated with each other. The drive gear mechanism 23 and the loading motor are provided in the roller chassis 13 so as not to be affected by the vertical swing of the roller chassis 13.

The loading operation of the first embodiment constructed as described above will be described for the case where the small-diameter disk 4 illustrated in FIGS. 2 and 3 is used.

When the disc 4 is pushed in through a front panel insertion opening of a player (not shown), the disc 4 guided by the conveying surface 18 of the roller base 20 and the upper plate 30 of the roller chassis 13 is conveyed to the lower edge near the center of the roller 11. The front end portion enters a rhombus-shaped gap formed by the surface 18 in a front view, the roller 11 is pushed up against the springs 22 and 22, and the lower edge of the roller 11 and the transport surface 18 cause the disk 4 to move.
The peripheral edge of the front end portion of the is clamped.

The loading motor rotates in the loading direction by the operation of a detection switch (not shown) that detects the insertion of the disc 4, the drive gear mechanism 23 is driven, and the roller 11 conveys the disc 4 toward the reproduction position.

The roller chassis is pivotally supported on the base 31, and the springs 38, 38 stretched between the roller chassis 35 and the roller base 31 allow the lower part of the upper roller 34 to slightly enter between the lower rollers 32, 33. In a standby position (not shown) in which the roller chassis 35 abuts the stopper 37, the lower edge of the upper roller 34 near the center and the lower rollers 32, 33 are pressed.
Each member is set so that a diamond-shaped gap in front view is formed by the upper edge of the central part of the.

When the small-diameter disk 4 is being conveyed, the lower edges of the upper and lower rollers 34 on both left and right sides enter between the lower rollers 32 and 33, as shown in FIG. The upper edges of the rollers 32 and 33 intersect, and the peripheral edge of the small-diameter disk 4 is sandwiched by these rollers 34, 32, and 33, so that the disk 4 can be reliably conveyed.

The drive for conveyance may be one of the upper roller 34 or the lower rollers 32, 34.

The number of upper rollers 34 may be two or more.

(Effect of the Invention) As described above, the disk transporting device according to the present invention has a roller base having a central portion formed low and gradually increasing in the left and right side portions, and a central portion having a small diameter and both side portions. Since the upper edge of the roller base and the lower edge of the roller can be gradually approached by a roller of a larger diameter, even a small-diameter disk, which was impossible with the conventional device, can be used for the upper edge and the lower edge of the intersecting central portion. The peripheral edge portion of the disk is reliably held by the edge and conveyed.

The central portion is formed to have a small diameter, and the diameter is gradually increased toward both sides to form the lower edge of the upper roller and the upper edge of the lower roller.
Even with a device capable of approaching even the intersecting shape, the peripheral portion of the small-diameter disk can be securely held.

As described above, according to the present invention, a small-diameter disk, which has hitherto been impossible, can be carried, and an economical loading device with high adaptability is provided.
