[Prior Art] Conventionally, slide devices that use plate-shaped rails to move objects back and forth have been widely used in various measuring machines, printing machines, and conveyance systems.

These slide devices can effectively accommodate various shapes of plate rails depending on the purpose, such as straight, curved, or ring-shaped rails. It is structured as follows. Specifically, many of them include a plurality of support rollers that engage with both ends of a plate-shaped rail and move back and forth, and a movable support plate that integrally locks each of the support rollers.

[Problem that the invention attempts to solve]

In such conventional examples, measuring machines, printing machines, etc.
Although it is used to move an object from one side to the other with highly precise strokes or reciprocate over a certain distance, the complicated structure of its attachments means that it does not have any protection against dust adhesion. The majority of them are those without.

For this reason, when a device that has been used by reciprocating within a predetermined range is used with a different stroke, there is a risk that dust adhering to the guide rails will stick to the oil and obstruct the expansion of the stroke. The microscopic dust generated and sometimes adhered solidifies, causing looseness in the movement of the movable support plate, causing measurement errors and placing an unnecessary burden on the driving means.

Further, if dust consisting of hard particles adheres, wear progresses rapidly, which makes it difficult to maintain accuracy, and furthermore, there are disadvantages such as accelerated deterioration of the entire device.

[Purpose of invention]

The present invention improves the disadvantages of the conventional example, and in particular prevents dust from adhering to the guide rollers, forcibly removes dust adhering to the guide rails, and thereby It is an object of the present invention to provide a slide device for a plate-shaped rail that can be smoothly moved at all times.

[Means for solving problems]

Therefore, the present invention includes a plurality of support rollers that engage with both side edges of a plate-shaped guide rail and move back and forth, and a movable support plate that integrally locks each of the support rollers. Then, each support roller is divided into two parts corresponding to one side edge portion and the other side edge portion of the plate-shaped guide rail, and each of the divided support roller portions is covered with a dustproof cover for the rail having a notch portion for the rail. A dust removal plate member for the rail is attached to each end face perpendicular to the moving direction of each dustproof cover for the rail, and is allowed to shift an appropriate amount in a plane parallel to the end face. Furthermore, a dust removal groove having the same shape as the cross-sectional shape of the rail edge is formed at one end of the rail dust removal plate member that comes into contact with the plate-shaped guide rail, and
A configuration is adopted in which a return mechanism for the rail dust removal plate member is provided at the end of the rail dust removal plate member opposite to the dust removal groove. This aims to achieve the above-mentioned purpose.
