Description

[Detailed Description of the Invention] The present invention relates to a document pressing device in an image forming device such as a copying machine, a printing machine, or an information recording device.

Hereinafter, a description will be given using a document pressing device of a copying machine as an example.

2. Description of the Related Art In copying machines, a document pressing device is used to fix a document to a document table during copying and to prevent light leakage from an exposure lamp.

However, with conventional document crimping devices, when you want to copy a large document, the edge of the document hits the fixed end of the document crimping plate, making it impossible to place the document in the optimal position, and forcing you to fold the document. There was something that had to be posted.

Further, since the opening/closing direction of the original pressing plate is regulated, it may be difficult to open/close the original pressing plate depending on the location where the copying machine is installed.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems and provides an original pressing device that can be easily attached to and removed from an original placing table.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of a copying machine to which an embodiment of the present invention is applied. In the figure, 1 is the copying machine main body, and 2 is a document mounting table made of a transparent glass plate. It is provided.

Reference numeral 3 denotes an original pressing plate, which is made of rigid plastic or hard rubber, and covers the original placed on the original placing table 2 temporarily for copying, and fixes the original on the original placing table 2. (not shown) to prevent light leakage.

The pressure bonding plate 3 may further be provided with a sponge layer or a soft white thin plate made of vinyl chloride, polypropylene, etc., integrally provided on the document pressure surface side.

Now, this crimp plate 3 has struts 4a and 4b attached to its two ends on the non-opening/closing side by rivets 5a and 5b.

The pillars 4a and 4b are elongated and cylindrical, and are made of a flexible material such as natural rubber, isoprene rubber, butadiene rubber, chloroprene rubber, urethane rubber, or the like.

These flexible supports 4a and 4b pass through open lowers a and 7b provided on the upper surface 1a of the copying machine main body 1, and support means 6a and 6b, which also have cylindrical interior spaces, are attached to the rear side plate 16. It is supported in a detachable manner.

Note that the support means 6a and 6b are fixed to the rear side plate 1b with screws 8a and 8b.

Therefore, in this embodiment, the pressure bonding plate 3 can be opened in the direction of the arrow a by grasping the gripping hand 2a.

At this time, the supports 4a and 4b are in a movable state and the supporting means 6a and 6 are
Since the supports 4a and 4b are made of a flexible member such as rubber, as the crimp plate 3 is opened in the direction of arrow a, the supports 4a and 4b move in the opening direction. The back plate 9 has an arched shape and is kept open to the pressure bonding plate 3 while the rear end 9a of the back plate 9 abuts against the upper surface 1a of the copying machine main body 1.

When the crimp plate 3 is closed, the struts 4a and 4b are released from bending and restored to the state shown in the first figure.

Furthermore, in the case of thick originals, the supports 4a and 4b are supported by the supporting means 6a.
・Even if the thickness of the original document is different on the left and right sides, the pillars 4a and 4b move by different amounts depending on the thickness of the document, and move the pressure bonding plate 3 along the thickness of the document. can be set.

Furthermore, when the size of the original is large, the pressure bonding plate 3 can be removed from the top surface 1 of the copying machine together with the supports 4a and 4b, so that it does not interfere with the placement of the large-sized original.

In addition, 10 stores the cut sheets in a cassette,
Reference numeral 11 is a tray for receiving cut sheets discharged from the main body of the copying machine after copying.

In addition, 12 is the operation panel of the copying machine main body, and the copy switch 12
A1 concentration adjustment dial 12b and the like are provided.

Still another embodiment will be described with reference to FIG.

Note that the same figure numbers as in FIG. 1 indicate the same members.

In this embodiment, the pressure bonding plate 3 is removably attached to the copying machine main body 1 by supports 13 provided at one location on both ends of the non-opening/closing side.

At this time, the support column 13 is made of the same flexible material as in the previous embodiment, is attached to the pressure bonding plate 3 with a rivet 14, and passes through an opening 15 provided in the top surface 1 of the copying machine to support the support means 16. is held in

The support means 16 is attached to the rear plate 1b of the copying machine main body 1 with screws 1.
It is attached by 7.

Therefore, in the case of this embodiment, since the support column 13 can be displaced in any direction, the pressure bonding plate 3 can be opened in a desired direction.

In this embodiment, an arch-shaped hook member 16 is fixed to the upper surface 1a of the copying machine main body 1, and this hook engages a hook-shaped member 19 provided on the upper surface of the pressure bonding plate 3 to the member 18. The pressure bonding plate 3 is maintained in an open state.

These hook members and hook-shaped members may be installed at multiple locations.

Furthermore, another embodiment will be described using FIG. 3.

This embodiment is an example in which the pressure bonding plate 20 and the support column 21 are integrally molded.

As for the material, for example, a flexible and flex crack-resistant material such as nitrile rubber or polyvinylcarbazole may be used, and the material may be integrally molded.

Incidentally, the integral molding may be carried out using any known and commonly used means.

In this embodiment as well, when the crimp plate is opened and closed, the strut 21 becomes arched and does not obstruct the opening operation.

Furthermore, if rubber is used as a flexible material, the specific gravity is light and the crimp plate and the support can be easily attached and detached as one unit.

Note that 22 is a clamp, which is used when opening and closing the crimp plate.

Furthermore, in FIG. 4, the crimp plate 23 and the support column 24 are integrally molded, and the support column 24 is attached to one end of the crimp plate 23.

Therefore, in this embodiment, similarly to the embodiment shown in FIG.
The pressure bonding plate 23 can be opened in a desired direction.

Note that 25 is a support tube provided in the copying machine main body 1, and supports the support column 24.

In this way, by integrally molding the support and the crimp plate, the number of parts can be reduced, and there will be no opening/closing problems due to poor attachment.

In the above embodiments, only cylindrical pillars were shown, but
The shape of the support is not limited to this.

In addition, it is better to make the size of the support support means slightly larger than the size of the support, which will not only make it easier to attach and remove the support, but also make it easier for the copying machine to bend when the crimp plate is opened. , it is easy to open and close the crimp plate.

As described above, the present invention provides a document crimping device that is easy to attach and detach, and is easy to open and close, since the support of the crimping plate is made of a flexible member.
