Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document placing device applied to a copying machine, an image reader or the like.

[0002]

2. Description of the Related Art In FIGS. 4 and 5, reference numeral 1 denotes a copying machine as a main body of the apparatus, and an original pressure plate 2 as an opening / closing member is provided on the upper surface of the copying machine 1. One end side of the document pressure plate 2 is rotatably connected at a position near the rear surface of the copying machine 1 as shown by A in FIG.

In the above structure, the user stands on the front side of the copying machine 1 and holds the free end 2-a of the document pressure plate 2 by hand to open / close the document pressure plate 2.

[0004]

When the user U is seated in a wheelchair, the reachable height of the hand H is lower than usual (the shoulder height is the height of the upper surface of the copying machine 1). , It is difficult to open and close the document pressure plate 2 (cannot be completely opened). If the original pressure plate 2 is inadvertently fully opened (angle of about 90 degrees with respect to the upper surface of the copying machine 1), the original pressure plate 2 cannot be closed because the hand H does not reach the free end 2-a.

When aligning the document D on the document placement surface, the document D is placed on the end faces of the horizontal index member 5 and the vertical index member 6.
It will hit the two sides of. The level difference between the document table glass 4 which is the document placement surface and the index surfaces of the horizontal index member 5 and the vertical index member 6 is small in order to secure the close contact between the document D and the document table glass 4. Since the end face of the vertical index member 6 is also present on the front side of the document placing surface, it is relatively easy to hit the document D, but the horizontal index member 5 is present only on the back side where the hand H is hard to reach. Therefore, when the document D is slid on the document mounting surface 4 and moved, the document D rushes onto the lateral index member 5 as shown in FIG. 5, and the document mounting position becomes inaccurate.

Furthermore, since the index surface is substantially horizontal, the line of sight S is parallel to the index surface when the user U views the index surface 5 at almost the same height, that is, when the user U is seated in a wheelchair. It becomes difficult to recognize whether the index of the lateral index member 5 on the back side is visible or not. Therefore, the document placement / positioning operation cannot be performed.

The present invention has been made in view of the above problems, and an object of the present invention is to ensure that the original pressure plate is in close contact with the original placing surface, and then the original is accurately placed on the original placing surface. An object of the present invention is to provide a document placing device that can be placed and allows a user whose line of sight is substantially at the same height as the index surface to easily see the index surface.

[0008]

In order to achieve the above object, the present invention provides a document placing device having an openable document pressure plate, wherein the document pressure plate has a main body mounting portion having a rotatable hinge and a document retainer. It is composed of two parts, and the document pressing part is supported by the main body mounting part so as to be rotatable in a direction approaching the document placement surface when the document pressure plate is opened. And

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show a form in which the present invention is applied to a copying machine. FIG. 1 is a diagram showing a state in which a user sitting on a wheelchair tries to place a document on the platen glass,
FIG. 2 is a view showing an open state (upper figure) and a closed state (lower figure) of the original pressure plate, and FIG. 3 shows an upper surface of the copying machine main body 1.

In FIG. 1, reference numeral 1 denotes a copying machine main body as an apparatus main body, and an original table glass 4 is attached to the upper surface of the copying machine main body 1 substantially horizontally. An optical system, an image forming unit and the like (not shown) are housed inside the copying machine main body 1.

A plate-shaped original pressure plate (opening / closing member) 20 is provided on the upper surface of the copying machine main body 1. The document pressure plate 20 is rotatably supported by a hinge A provided at a position on the inner side of the upper surface of the copying machine body 1. This hinge A is designed so that the document pressure plate 20 can be stopped at an arbitrary angle. Document pressure plate 2
Reference numeral 0 includes a main body mounting portion 21 having a hinge A and a document pressing portion 22 having a pad 3 for pressing a document. The document pressing portion 22 is rotatably supported by the hinge B with respect to the main body mounting portion 21. . Like the hinge A, the hinge B can also stop the main body attachment portion 21 and the document pressing portion 22 at an arbitrary relative angle, so that there is no obstacle when a healthy person opens and closes the document pressure plate 20.

Further, since the original pressing portion 22 is rotatable only in the direction in which the original pressing plate 20 approaches the original table glass 4 when the original pressing plate 20 is open, when the original pressing plate 20 is closed, the original D is surely placed on the original table glass. Can be closely attached to 4.

A light reflecting means 23 is arranged on the main body mounting portion 21 of the document pressure plate 20. The user U can see the lateral index member 27 disposed on the back side of the document table glass 4 through the light reflecting member 23. At this time, the lateral index member 2
7 has a display by a mirror image index in addition to the normal index, so that the index will not be misidentified because it looks like an upright index even through the light reflecting means 23. The line-of-sight S1 for directly looking at the lateral index member 27 has an angle close to horizontal, so that the display of the index is difficult to see and the sense of distance is difficult to grasp. In S2, since the viewpoint is from above, the state of the front end of the document D and the position of the fingertip can be confirmed. Further, the hand H of the user U holding the document does not block the line of sight S2.

Next, the operation of the document regulating member will be described.

A slide lever 24 is arranged inside the main body mounting portion 21 of the document pressure plate 20. The slide lever 24 is slidably supported by a hinge A and a guide pin 21-a provided on the main body mounting portion 21,
One end 24-a of the slide lever 24 is urged by a spring means (not shown) so as to come into contact with a protrusion 22-a provided on the document pressing portion 22.

Reference numeral 25 denotes a swing lever disposed inside the main body 1 of the copying machine, which is rotatable with respect to the axis C, but is a stopper (not shown) so as not to rotate clockwise from the state shown in the lower diagram of FIG. It is regulated by. Reference numeral 26 is a document regulating member which is vertically movable between the document table glass 4 and the lateral index member 27.

The document regulating member 26 is biased downward by a spring means (not shown), but its downward movement is restricted by one end 25-b of the swing lever 25. Document pressure plate 2
When 0 is in the closed state and when the main body attaching portion 21 of the original pressure plate 20 and the original pressing portion 22 are in the parallel state, the slide lever 24 is in a position close to the hinge B.

While pressing the original pressing plate 20, the original pressing portion 22
When the document is pushed forward with respect to the main body mounting portion 21, the protrusion 22-a of the document pressing portion 22 causes one end 2 of the slide lever 24 to move.
4-a is pushed and the slide lever 24 moves in the direction away from the hinge B. By this operation, the slide lever 24
The other end 24-b pushes one end 25-a of the swing lever 25 to rotate the swing lever 25 counterclockwise. At this time, the other end 25-b of the rocking lever 25 is attached to the document regulating member 26.
Is pushed up to project from the lateral index member 27. Since the document regulating member 26 projects from the lateral index member 27, it is possible to prevent the leading edge of the document D from riding on the lateral index member 27, and accurate document alignment becomes possible.

[0020]

As is apparent from the above description, according to the present invention, since the original document pressing portion of the original document pressing plate can be turned to the front side when the original document pressing plate is opened, the original document pressing plate can be held while the user is sitting on the wheelchair. The free end can be grasped, and the opening / closing operability of the opening / closing member is improved.

On the original pressure plate, the display of the lateral index member can be confirmed through the light reflecting means provided on the main body mounting portion of the original pressure plate. Further, since the normal indicator and the mirror image indicator are displayed on the lateral index member, the document positioning operation can be performed without misreading the display.

Further, when the original is placed on the original placing surface in alignment with the index surface, the original restricting member projects from the index member, so that the original can be accurately positioned without riding on the index member, and the original is placed. Accuracy can be secured.
