There are things that have been done.

A document holding device like the one disclosed in this publication is usually mounted in a forward-inclined position to facilitate opening and closing operations. In other words, if the document holding device is opened more than 90 degrees from the horizontal document loading surface, if there is a wall on the back of the copier, the document holding device will hit the wall when opened. When folding or closing, the door must be raised to 90 degrees before closing, making it difficult to operate, so it is designed not to open more than 90 degrees.

[Problem to be solved by the invention] However, when attaching such a document holding device to a copying machine, if it is kept in the forward leaning position as described above, it tends to fall forward, so it is necessary to support the document holding device with one hand or use another hand. We need people to support us. In particular, the document holding device simply holds the document, blocks external light,
In the case of a so-called automatic document feeder (ADF), which not only has a cover function to provide a blank back of the original but also has an automatic document feeding function, it is large in size and weighs considerably. If you keep leaning forward like in the bulletin, you will fall forward,
The problem was that it was very difficult to install.

[Purpose of the invention] The purpose of this invention is to provide a hinge device that facilitates the work of attaching a document holding device to an image processing device, and that allows the document holding device to be set at an appropriate opening angle for use after installation is completed. be.

[Example] Hereinafter, an example of this invention will be described with reference to FIGS. 1 to 3.

In this embodiment, as shown in FIG. 1, a document holding device D such as an automatic document feeder is attached to an image processing device C such as a copying machine via a hinge device A so as to be openable and closable.

This hinge device A includes a first attachment portion 3 attached to the back 1 of the image processing device C as shown in FIG. 2, and a second attachment portion 3 attached to the document holding device D.
and a shaft member 12 that rotatably connects the first and second attachment portions 3 and 7.
and a biasing means 17 such as a spring that biases the document holding device D in the opening direction, so that when the document holding device D is opened, the document holding device D is regulated to a predetermined angle in an upright state. ing.

The first attachment part 3 engages with a first restriction part 3a provided on the upper edge as shown in FIG. and a narrow protrusion 4b protruding forward from the coupling part 4.

On the other hand, the second attaching part 7 engages with the first regulating part 3a as shown in FIG.
The frame 5 of the document holding device D has a second regulating portion 7a that regulates the document to a predetermined angle in an upright state, and a coupling portion 8 that protrudes to sandwich the coupling portion 4 of the mounting portion 3. It is fixed with screw 6.
An L-shaped fixing plate 9 is fixed to the upper surface of the mounting portion 7 with screws 10, and the fixing plate 9 is further fixed to the vertical portion of the frame 5 with screws 11.

The mounting portion 3 and the mounting portion 7 are rotatably coupled by a shaft member 12 at the coupling portion 4 and the coupling portion 8.

A support portion 14 is rotatably attached to the protruding portion 4 b of the coupling portion 4 by a shaft member 13 . A rod 15 is attached to the support portion 14, and a holding portion 16 is slidably fitted to each tip. The urging means 17 for urging the document holding device D in the opening direction is interposed between the support portion 14 and the holding portion 16.

Furthermore, as shown in FIG.
and the second regulating part 7 of the attachment part 7.
An opening E is formed between the opening E and the opening E.

This opening E is wide open when the document holding device D covers the document set surface of the image processing device C, but as the document holding device D is opened upward, the opening area becomes narrower. When the document holding device D stands upright almost vertically, the second regulating portion 7a of the mounting portion 7 and the first regulating portion 3a of the mounting portion 3 directly engage with each other, so that the document holding device D stands upright. In addition to being regulated to a predetermined angle,
The opening E is virtually eliminated.

A regulating member 18 as a stopper as shown in FIG. 3 is interposed in the opening E. As shown in FIG.

This regulating member 18 is formed by bending on both sides of the support plate 19 that contacts the inside of the attachment part 3 or the second regulation part 7a of the attachment part 7, and when the document holding device D is opened. The arm part 20 has an inclined part 20a that engages with the second regulating part 7a of the attachment part 7 to regulate the opening angle of the document holding device D to be smaller than the predetermined angle.

Note that the arm portion 20 is formed with a recess 20b that engages with the shaft member 12.

In the above configuration, in order to attach the document holding device D to the image processing device C, first, the second attaching portion 7 is fixed to the frame 5 with screws 6, and the fixing plate 9 is similarly fixed with screws 10 and 11. Incidentally, at this time, the regulating member 18 is not attached.

In the above state, the attachment part 3 and the attachment part 7 are relatively opened by the urging force of the urging means 17,
The first regulating portion 3a of the attachment portion 3 and the attachment portion 7
is in contact with the second regulating portion 7a. Therefore, when attaching the attaching portion 3 to the back portion 1 of the image processing apparatus C, the document holding device D is placed in an upwardly standing position.

Therefore, the image processing device C
When it is locked at the upper corner of the document holding device D, the line of gravitational force acting on the center of gravity of the document holding device D passes approximately through this corner 4a,
The moment that forces the document holding device D to fall forward or backward is small and can be directed with just a slight touch of the hand, making it easy to tighten the screws 2 and to easily fix the mounting portion 3 to the image processing device C.

When the connection of the document holding device D to the image processing device C is completed, the document holding device D is pulled down toward the document setting surface. As a result, the opening E is opened wide, and the regulating member 18 is fitted through the opening E as shown by the solid line in FIG. 2 and fixed with the screw 22. Then, when the document holding device D is opened gently, the second regulating part 7a of the attachment part 7 engages with the optimum position of the inclined part 20a of the arm part 20 of the regulating member 18, and a predetermined opening angle is secured. Installation of document holding device D is completed.

On the other hand, the regulating member 18 can also be attached as shown by the broken line in FIG.

That is, rotate the attachment part 3 side inward around the shaft member 12, bend it as shown in FIG. 2, and insert the support plate 19 of the regulating member 18 toward the support part 14 side as shown by the broken line. , recessed portion 20 of arm portion 20
b is engaged with the shaft 12 and the screw 22 is screwed into the screw hole 21 to fix the regulating member 18 to the attachment part 3. As a result, the support plate 19 and the second restricting part 7a of the attachment part 7 are engaged, the attachment part 7 is locked, and the hinge device A remains in the bent state.

Then, the document holding device D is placed on the document setting surface of the image processing device C. Since the hinge device A has already been bent at right angles, the mounting portion 3 is fixed to the back portion 1 with screws 2 as is. In other words, the opening angle of the document holding device D can be changed simply by changing the mounting direction of the regulating member 18.

Next, the screw 22 is removed and the regulating member 18 is taken out, and the regulating member 18 is attached as shown by the solid line in FIG. 2 and fixed with the screw 22. As a result, when the document holding device D is opened, the second restricting portion 7a engages with the inclined portion 20a, and the opening angle is restricted to an appropriate value.

FIG. 4 shows another embodiment of the hinge device.

In the hinge device B of this embodiment, the regulating member 23 has a rectangular parallelepiped shape, and by removing the regulating member 23 or attaching it as shown in the solid line or broken line in the figure, the first and second attachment parts 3, 7 can be parallel to each other, can be restricted to a predetermined opening angle, or can be restricted to be perpendicular to each other.

It should be noted that the form of the regulating member is not limited to those of the above embodiments, and it is clear that various forms can be considered within the spirit of the invention.
