レールの故障の原因ともなる問題があった。2. Description of the Related Art Conventionally, the above-mentioned slide rail slides through a fixed side rail having a substantially C-shaped cross section which is fixed to an apparatus body, and a plurality of balls rotatably held by a ball retainer on the fixed side rail. The movable side rail is movably held and has a substantially C-shaped cross section. The fixed side rail and the movable side rail have substantially the same length, and the ball retainer has a length of about one half of that length. . That is, the moving-side rail (developing unit or the like in which the moving-side rail is connected to the left and right ends)
With completely stored on the fixed side rail (device body),
The ball retainer (a plurality of balls) is located at the rear side of the fixed side rail and the moving side rail, and supports the developing unit (moving side rail) in this range, and the front side of the moving side rail is the fixed side rail. Is not substantially supported. There is no particular problem in the above-mentioned condition when using a light load such as a drawer.However, when using a heavy load such as a developing unit, the front end of the moving side rail is It shifts downward (the front end of the ball becomes the fulcrum,
The front end side is lowered), which is a so-called forward drooping state, and not only the developing unit cannot be stored at a predetermined position, but also a failure of the slide rail.

れている。In order to solve this problem, as shown in FIG. 4, the front end of the fixed side rail a is fitted in the ball sliding groove c between the moving side rail b and the fixed side rail a, and is moved in the front-rear direction. Provided is a support member e having a columnar fitting support portion d formed in a predetermined length, and the lower fitting support portion d supports the bent edge b1 below the moving rail b. In addition, there is provided a slide rail that prevents the moving-side rail b from falling forward.

In the state, the moving side rail b is slightly shifted from the predetermined position with respect to the fixed side rail a in a direction approaching or away from the substrate a1 of the fixed side rail a by an accuracy variation of the left and right width of the developing unit and the like. Becomes That is, since the fitting support portions d, d of the support member e are formed in a cylindrical shape, the outer surface of the sliding groove of the moving side rail b and the contact portion (contact area) of the fitting support portions d, d are formed. Then, there is a problem that a part of the outer surface of the sliding groove of the moving side rail b comes into strong contact with a part of the fitting support part d, and the sliding of the moving side rail b becomes heavy.

There is a case where the bent edge b1 gets over the fitting support portions d, d due to the elastic warpage of the moving side rail b protruding forward (the state shown by the phantom line in FIG. 3).

No force is applied again from the other side to force the bent edge b1
End of the support rails d, d, and the sliding groove and the fitting support parts d, d were fitted. However, if too much force is applied, on the other hand, the opposite moving side rail b May be disengaged from the fitting support portion d, so that a delicate force adjustment is required, and the operation becomes more complicated.

On the sides 1 and 21, there are substantially horizontal supporting surfaces 531 and 531 for supporting the inner sides of the bent edges 21 and 21 of the moving side rail 2, and the end face of the board 22 on the side of the board 22 of the moving side rail 2. It is formed on a substantially arc-shaped surface 532, 532 close to the inner surface. The support member 5 is configured as described above,
At the position of the positioning projection 15, one of the fitting projections 52 is fitted into the ball sliding groove 10 from the inner surface side of the moving side rail 1, and the other fitting projection 52 is fitted to the other bent edge 11. When pressed, the bent edge fitting groove 54 is formed, so that elastic deformation occurs in the continuous portion of the fitting protrusion 52 and the mounting board 51, and the fitting protrusion 52 is inserted into the other ball sliding groove 11. At the same time, the fitting holes 511 are fitted into the positioning protrusions 15, and the movement of the support member 5 in the sliding direction is prevented.

3, 53 and the fitting projections 52, 52 have no effect on the sliding force as in the prior art.
Also, even if a load is applied to the moving rail 2, the inner surface of the upper bent edge 21 is supported by being in contact with the supporting surface 531 of the upper supporting projection 53, so that the moving rail 2 is not moved forward. Even if the moving side rail 2 protruding forward of the ball retainer 3 is elastically warped even if a force is unexpectedly applied to the moving side rail 2 from the side at the position in the middle of the movement without moving up. Since the support surface 531 is formed in a substantially horizontal shape, the bent edge 21 only moves on the support surface 531 and returns to the original position when the applied force is released. The support protrusions 52 are formed vertically so that the slide rail can be used for both left and right.

こす事がない。According to the first aspect of the present invention, the support member has a support protrusion protruding in the direction of the board of the movable rail and supporting the inner surface of the bent edge of the movable rail. Therefore, even if the moving side rail slightly shifts in the direction of the fixed side rail due to the precision variation of the developing unit, the ball sliding groove of the moving side rail (because it supports the inside of the bent edge, ), Since it is irrelevant to the support projection, it does not affect the sliding force as in the prior art. Further, even if a load is applied to the movable rail, the movable rail does not sag forward because it is supported by being in contact with the upper support protrusion on the inner surface of the upper bent edge.

With the support projection, a force is unexpectedly applied to the moving rail from the side at the position where the moving rail is moving, and the moving rail protruding forward of the ball retainer is elastic. Even if it is warped, the bent edge only moves on the horizontal plane, so that when the applied force is released, it can return to the original position.

業が非常に容易である。According to the third aspect of the present invention, in addition to the above-described effects, the support member has a fitting protrusion having a substantially semicircular cross section fitted into the ball sliding groove of the fixed rail, and a fitting protrusion. Since there is a bent edge fitting groove in which the bent edge of the moving side rail is located at a predetermined distance from the portion, the mounting work on the fixed side rail is very easy.
