FIG. 9 is a plan view of the guide body, and FIG. 10 is a view showing the relationship between the finger placed on the slide rail and the document table.

The manuscript table movable copying machine of this embodiment is shown in FIG.
As shown in FIG. 2, the manuscript table 2 is movably provided on the upper surface of the copying machine main body 1, and the moving body 10 is fixed to the manuscript table 2 so as not to project to the outside of the manuscript table 2. ,
It is slidably supported by a guide body 11 fixed to the copying machine main body 1.

The document table 2 is a document cover 1 which can be opened and closed.
2 and a support plate 13 below the support plate 13.
A glass plate also serving as a document placing table is adhered on the glass plate, and the document is set on the glass plate to make a copy.

The document table 2 is attached to the slide rail through the support plate 13. Further, a rack gear is attached to the support plate 13, and the rack gear receives the drive from the copying machine main body 1 by the motor to move the document table 2 along the slide rail.

The slide rail, the moving body 10 and the guide body 11, the ball 14 for reducing the load during movement and obtaining a stable movement, and the ball 14 for moving the moving body 1
It is constituted by a retainer 15 sandwiched and supported between 0 and the guide body 11.

The moving body 10 is formed in a downward U-shape, and the guide body 11 is formed in an upward J-shape, facing each other and not in direct contact with each other as shown in FIG.

Since the ball 14 is interposed, when the moving body 10 moves L in the direction of the arrow E in FIG. 6, the movement causes the ball 14 to rotate and the retainer 15 supporting the ball 14 to move. It means that L is moved during the moving body 10. Further, at this time, the rotation of the ball 14 causes the guide body 1 to rotate.
Since it is also transmitted to 4, the guide body 11 always moves at a ratio of 2: 1. With these effects, the slide rail can reduce the load during movement.

Here, unless the retainer 15 is attached to the moving body 10 so that the retainer 15 does not come off, the slide rails will fall apart when moving too much.

Therefore, a movement restricting portion 16 for preventing the moving body 10 from coming out of the guide body 11 is provided.

As shown in FIG. 7, the movement restricting portion 16 has first and second outer pieces 20 and 21 in which a part of both ends of the moving body 10 is cut out and bent downward, and as shown in FIG. First and second inner pieces 22 and 23 bent downward at both ends of the retainer 15, and first and second projecting pieces bent upward by cutting out an intermediate portion of the guide body 11 as shown in FIG. 24 and 25.

As shown in FIG. 3, before the original table 2 is moved, the second inner piece 23 contacts the first projecting piece 24, and the second outer piece 21 contacts the second inner piece 23. The movable body 10 is in contact with and prevented from moving leftward in the drawing.

Further, as shown in FIG. 4, after the document table 2 is moved, the first inner piece 22 comes into contact with the second projecting piece 25, and the first outer piece 20 comes into contact with the first inner piece 22. The moving body 10 is regulated so as not to move further to the right.

The positional relationship in the width direction of each of the outer piece, the inner piece, and the projecting piece is a ₁ , a ₂ , b ₁ , shown in FIGS.
For b ₂ , c, d, e ₁ , e ₂ , f ₁ , f ₂ , g, h, b ₁ > a ₁ > c, b ₁ >d> c, d> f ₁ + t, d
> E ₁ + t, f ₂ > e ₂ > g, f ₂ >h> g, h> a ₂
+ T, h> b ₂ + t (where t is the thickness of the guide body 11)
Therefore, the first and second protrusions 24, 2 are
5 is between the first and second outer pieces 20 and 21, and the width of the first and second inner pieces 22 and 23 is wider than the distance between the first outer piece 20 and the second outer piece 21.

The length from the right end of the moving body 10 shown in FIG. 3 to the right end of the second projecting piece 25 in order to prevent the two abutting places from protruding to the outside of the document table 2. The length X ₂ from X ₁ and the left end of the moving body 10 shown in FIG. 4 to the left end of the first projecting piece 24 is set close to zero or becomes negative. Further, the width of the document table 2 or the table support plate 13 is set to x ₁ + x ₂ + x ₃ (x ₃ is the guide member 11).
(Width of) (x ₁ + x ₂ + x ₃ + α)
Then, the first and second projecting pieces 24 and 25 will not come out of the document table 2.

As shown in FIG. 1, a shielding plate 26 bent downward is provided at the end of the support plate 13, and the distance between the lower end of the shielding plate 26 and the guide body 11 is set. ,
It is set to 4 mm or less.

By constructing the slide rails as described above, when the user inadvertently moves the document table 2 too much, the retainer 1 moves as the moving body 10 moves.
5 also moves, and the first inner piece 22 of the retainer 15 moves to the guide body 1.
When the first outer piece 20 of the moving body 10 comes into contact with the first inner piece 22 of the moving body 10,
Movement is regulated.

Alternatively, even if the first projecting piece 24 and the second outer piece 21 come into contact with the second inner piece 23, the movement of the moving body 10 is restricted. Therefore, when the document table 2 comes off the guide body 11 and falls, it is possible to prevent the occurrence of trouble.

Since the movement restricting portion 16 does not extend outside the document table 2, the finger is not caught and the finger is not caught.

Moreover, since the cover plate 26 prevents the fingers from entering the inside of the document table 2, the safety can be further enhanced.

In addition, even if the movement restricting portion on the document table 2 side is damaged, since the shielding plate 26 is restricted by the movement restricting portion on the main body side, the damage can be minimized.

Therefore, in order to enhance the safety as in the conventional case, it is not necessary to add an additional plate, and it is possible to prevent the original table 2 from coming off and falling without cost increase only by processing the members. Moreover, it is possible to prevent the fingers from being caught.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention.

In the present embodiment, the shielding plate 26 is formed on the support plate 13, but the original cover 12 or the moving body 10 is not shown.
You may form in.

[0035]

As is apparent from the above description, according to the present invention, the guide is fixed to the document table so that the moving body does not protrude outside the document table, and the moving body is fixed to the main body of the copying machine. A movement restricting portion that is slidably supported by the body and that prevents the moving body from coming out of the guide body is provided, and since the movement restricting portion is arranged inside the document table,
In order to improve safety as in the past, it is not necessary to add an extra plate, it is possible to prevent the platen from coming off and falling without cutting the cost by simply processing the members, and it is also possible for fingers to be caught. It can be prevented.

According to the second aspect of the present invention, the manuscript table is provided with the finger-stuffing prevention shielding plate for covering the moving body so as not to be exposed to the outside. Can be prevented and safety can be increased.

In addition, even if the movement restricting portion on the document table side is damaged, the damage is minimized because the shielding plate is restricted by the movement restricting portion on the main body side.
