Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slide device for a document moving table of a copying machine, which is used in a copying machine such as an electrostatic copying machine and moves a document for image scanning. Conventionally, in a copying machine in which a copy document is placed on a movable table and the movable table is slid horizontally to scan the image, a part of the slide device is exposed due to the movement of the movable table. Dirt and dust may get inside the slide device and obstruct its movement, or the exposed stopper protrusion that restricts the movement range may accidentally injure your fingertips. There was a danger of pinching one's fingertips in some areas. The present invention is intended to eliminate the above-mentioned drawbacks, and aims to provide a slide device for an original moving table that is simple in structure and inexpensive.

Hereinafter, the present invention will be explained based on the drawings.

A is a document placement plate made of a rectangular glass plate, C
1 is a cover provided on the upper part of the mounting plate A, 1 is a document moving table that holds the placing plate A, (hereinafter simply referred to as the moving table) 2 is a slide provided on the bottom surface of the end of the moving table 1. The device 3 is a support plate for fixing the slide device 2. The slide device 2 includes an outer member 4 that is fixed to the lower surface of the movable base 1 and moves together with the movable base 1, and an inner member 5 that is fixed to the support plate 3 and into which the outer member 4 is inserted.
The ball retainer 6 is fitted between an outer member 4 and an inner member 5. The outer member 4 has ball guide grooves 41, 4 in the longitudinal direction of the inner surface formed by curving the front and rear ends of a band-shaped metal plate into an inward arc shape or a V shape.
1, the front and rear bent edges 42, 42 and the substrate 43 form a downward substantially C-shaped cross section. and,
A portion of the left and right ends of the base plate 43 of the outer member 4 is cut inward to form the retainer front and rear stoppers 4.
4, 45 are formed, and movable table mounting holes 46 are provided at a predetermined number of positions in the left and right direction of the substrate 43, and mounting nuts 47 are fixed to the inner surfaces of the mounting holes 46. The inner member 5 is approximately the same length as the outer member 4, is made of a band-shaped metal plate, is large enough to allow the outer member 4 to be inserted into the outer member 4, and has its front and rear ends curved outward in an arc shape or a V shape. Ball guide grooves 51, 51 are formed in the longitudinal direction of the outer surface.
The front and rear bent edges 52, 52 and the substrate 53 form an upwardly C-shaped cross section. Then, a part of the base plate 53 of the inner member 5 is cut and raised toward the outer member 4 side to form a retainer stopper 54 and mounting holes 55 for the support base 3 at a predetermined number of positions in the left and right direction of the base plate 53. The ball retainer 6 is made of a band-shaped metal plate and has a length about half of the members 4 and 5, and includes an upwardly facing U-shaped substrate 61, a front and rear bent piece 62 with the front and rear ends of the substrate 61 bent downward, Balls 63 are rotatably held at several locations in the longitudinal direction of the base plate 62, and a portion of the base plate 31 is made to protrude rearward to form a stopper protrusion 64. In the drawing, the ball retainer 6 has a shape in which the front and rear bent pieces 62, 62 are connected to the left and right, but in order to reduce the weight, the parts other than the parts that hold the balls 63 are cut off. Good too. Reference numeral 7 denotes a gap concealing member, which is made of a band-shaped plate of synthetic resin or aluminum and is attached to the entire length of the inner surface of the base plate 53 of the inner member 5, and includes a retainer stopper 54 and a mounting hole 55 provided in the inner member 5.
Notch hole 71 and escape hole 7 at the location corresponding to...
2..., the upper end of the retainer stopper 54 slightly protrudes from the upper end surface 73 of the gap concealing member 7,
The ball retainer 6 is formed in such a thickness that there is a considerable gap between the ball retainer 6 and the base plate 1 of the ball retainer 6. This slide device has the above-mentioned configuration, and the slide device 2 is configured with both members 4 and 5 and the ball retainer 6 inserted into each other, and the inner member 5 side of the slide device 2 is placed in a predetermined position on the support plate 3. Place the retainer in the position with the retainer stopper 54 side facing outward,
The outer member 4 is moved left and right, and the inner member 5 is fixed to the support plate 3 with bolts B. At this time, the head of the bolt B does not protrude above the upper end surface 73 due to the relief hole of the gap concealing member 7. Next, the end of the movable table 1 is placed on the outer member 4, and the movable table 1 and the outer member 4 are fixed with bolts B from above.

When copying a document, the movable table 1 configured as described above first moves inward of the support plate 3 to increase the moving distance, and then moves to the outside of the support plate 3 again from a predetermined position. move in the direction. At this time, along with the above movement, outer member 4
The ball retainer 6 also moves together with the moving table 1.
When the outer member 4 has moved half of the moving distance and has moved to the maximum outward direction of the support plate 3, the stopper protrusion 64 of the ball retainer 6
is in contact with the upper right side of the retainer stopper 54 of the inner member 5, and the retainer back stopper 45 of the outer member 4 is in contact with the right end of the ball retainer 6, and the movable table 1 is temporarily stopped, and then the inner side of the support plate 3 is pressed again. move in the direction. If the number of copies is large, the above operation will be repeated.
When the movable table 1 moves inward of the support plate 3 to a predetermined position, a retainer stopper 54 provided on the inner member 5 is exposed. At this time, conventionally, if the user's fingertip or the like is accidentally placed on the base plate 53 of the inner member 5, the left end surface of the outer member 4 moving toward the outside of the support plate 3 and the retainer stopper 54 There was a risk of a serious accident occurring. In the present invention, the gap concealing member 7 is provided on the inner surface of the substrate 53 of the inner member 5.
is attached to the upper end surface 73, the upper end of the stopper protrusion 54, and the outer member 4.
Since the distance between the inner member 5 and the inner member 5 is small, the fingertip is pushed by the outer member 4 and slips out to the outside of the inner member 5. In the present invention, the retainer stopper 54 is provided on the bent edge 52 side of the board 53, but it may also be provided in the center of the board so that the left end of the ball retainer 6 comes into contact with it. Needless to say, the retainer stopper 54 may be provided only on the ball retainer 6 side, or a slide device may be attached as shown in FIG. 4. Furthermore, in the present invention, since the outer member 4 is located on the moving table 1 side, it covers the ball retainer 6 and the inner member 5 from above, preventing dirt and dust from entering into the slide device 2. can be prevented.

As described above, the present invention has a simple structure consisting of an outer member, an inner member, and a ball retainer, and is a practical and useful invention, as it can be used safely and manufactured at low cost due to the gap concealing member. .
