Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a document holding cover device in an electrophotographic copying machine. .

0002

[Conventional technology]

FIGS. 6 and 7 show, for example, the conventional document press shown in Japanese Utility Model Application No. 61-128640. 1 is a configuration diagram showing a cover device, in which 1 is a document reading device, and 2 is a diagram showing a document 11 on a glass. A document holding cover 4 is attached to the document reading device 1 to keep it in close contact with the plate 3. A hinge mechanism 5 is attached to the inside of the document holding cover 2. It is a cushioning material.

0003 Next, the operation will be explained. In FIG. 7, the original 11 is placed in the glass of the original reading device 1. The document holding cover 2 is closed from above the document 11. Manuscript 11th place If the document is misplaced, open the document holding cover 2, set the document 11 correctly, and then try again. Close the document holding cover 2. Next, a copying operation is performed. At this time, press the document holding cover 2. The original 11 is prevented from moving by the cushioning material 5 adhered to the inside.

0004

[Problem that the idea aims to solve]

Since the conventional document holding cover device 1 is configured as described above, the document holding cover device 1 is configured as described above. When the document 11 has folds or bends, it may be caused by the wind pressure when closing the bar 2. For example, when copying a part of a large document 11 such as a newspaper, the position of the document 11 is It is easy to misplace the document 11, and it is difficult to notice that the document 11 is misaligned after closing the document holder cover. If you suspect that the document is misaligned, open the document holding cover 2 again. You must reset the original 11 or discover a misalignment of the original 11 after copying and copy again. There was a problem that it had to be done.

[0005] This idea was made to solve the above problems, and the original presser cover A transparent plate 7 is rotatably installed inside the document 11 by using this transparent plate 7. It is easy to check that there is no positional deviation, so there is no need to re-copy due to positional deviation. The object is to obtain a document holding cover device 1.

[0006]

[Means to solve the problem]

The document holding cover device according to this invention has a transparent plate on the inside 2a of the document holding cover 2. 7 is installed so that it can be opened and closed freely, and this transparent plate 7 and document holding cover 2 are connected. An engaging portion 10 is provided for removably fixing.

[0007]

[Effect]

The document holding cover device 1 in this invention is installed inside 2a of the document holding cover 2. Since the original 11 is held down by the transparent plate 7, it is possible to eliminate misalignment of the original 11. Ru. The transparent plate 7 and document holding cover 2 may be opened and closed individually or both at the same time. I can do it.

【Example】

Example 1. An embodiment of this invention will be described below with reference to the drawings. Figures 1 and 2 are the origin of this idea. Figures 3, 4, and 5 are diagrams of the main components of the document presser cover device, and are diagrams explaining its operation. . In each figure, 1 is a document reading device with a rotation fulcrum A1a at the top, and 2 is an inside side. A document holding cover for holding the document 11 in close contact with the glass plate 3, with 2a as a pressure bonding surface. , 7 has a rotation fulcrum B7a at one end and a notch 7c on the front surface 7b, and holds the original 11. 8 is a rotational fulcrum corresponding to the fulcrum when opening and closing the original holding cover 2; 9 is a support shaft pin that rotatably connects the rotation fulcrum A1a and the rotation fulcrum B7a; 10 is a support shaft pin that rotatably connects the rotation fulcrum A1a and the rotation fulcrum B7a; This is an engaging part for fixing the transparent plate 7 to the document holding cover 2, and the engagement piece at the tip is attached to the transparent plate. It is removably engaged with the notch 7c of No.7. 11 is the original to be copied.

[0009] Explain the function of each configuration. The transparent plate 7 can be used alone or fixed to the document holding cover 2. The transparent plate 7 and the document holding cover 2 can be opened and closed at the same time as the document holding cover 2. The engaging portion 10 that fixes the can be engaged and disengaged with a single touch. Upper part of document reading device 1 The rotation fulcrum A1a and the rotation fulcrum B7a provided at one end of the transparent plate 7 are connected to the support shaft pin 9. The transparent plate 7 can be opened and closed rotatably.

0010 A specific copying operation will be explained. In Figure 3, when copying, original 1 1 at a fixed position above the glass plate 3 of the document reading device 1. In Figure 4, the original Release the engaging part 10 provided on the front side of the document holding cover 2, and bring the transparent plate 7 into close contact with the document 11. let It is confirmed through the transparent plate 7 whether the original 11 has shifted from its normal position. too If the misalignment is found, the transparent plate 7 is opened and the original 11 is set in the normal position again. Figure 5 Close the document holding cover 2 at . In this case, the engaging portion 10 of the document holding cover 2 Since the notch 7c of the transparent plate 7 is engaged, replace the original 11 after copying. At this time, the transparent plate 7 is also opened together with the document holding cover 2.

[0011] Example 2. In the embodiment described above, the rotation fulcrum A1a formed at the top of the document reading device 1 is fixed. As shown in the case, the rotation fulcrum A1a is structured to be able to move in the vertical direction, and the original The transparent plate 7 may be movably adjusted in the vertical direction depending on the thickness of the transparent plate 11. Ma In addition, in the above embodiment, the case was explained in which the transparent plate 7 was provided, but when copying thick originals, When copying, use a transparent elastic sheet to improve adhesion to the original 11. You may.

0012

[Effect of the idea]

As described above, according to this invention, the document holding cover is made of a transparent plate, so the original Misalignment of the original can be easily detected and corrected, which prevents misalignment of the original and eliminates waste. Copying can be prevented.
