Abstract

PURPOSE:To copy bound materials or the like easily in an accurate position, by constituting a transparent plate, where an original is placed, so that its center part is deformed from the upward projecting two-folded state to the one-plane state. CONSTITUTION:Transparent plates 19 and 20 are fitted to frames 11 and 15 and are fixed and are connected by two, front and rear pins 13 so as to be folded double freely. One side of the transparent plate 19 is hinged to a supporting part 5 by a pin 9, and one side of the transparent plate 20 is brought into contact with the upper face of a copying machine through a guide roller 18. A coil spring 25 is strong enough to keep movable parts such as transparent plates and an original, which is placed on them, bent. Originals bound in the center are centered and are set on transparent plates 19 and 20 and are depressed against the force of the spring 25 to bring closely originals into contact with transparent plates, and they are copied. Since the center of the original is set to a predetermined position, each page of originals is copied in an accurate position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a means for facilitating the loading of original documents when copying printed materials, books, etc. with a copying machine having a flat original table.

FIGS. 1 and 2 show a conventional copying machine and the state in which it copies bound materials. In FIG. 1, 1 is the upper part of the electronic copying machine, 2 is a transparent glass plate on which an original to be copied is mounted, and 3 is a bound original to be copied. In conventional copying machines, when attempting to load a bound original 3 onto the glass plate 2 of the copying machine, the original 3 is first placed on the glass plate 2 as shown in Figure 1.
The tips 3m and 3b of the page to be copied are on the glass plate 21
2a and 2b. Thereafter, when the original 3 is pressed downward to a position where it can be copied, the original 3 will be in the state shown in FIG. At this time, the leading edge 3a of the page to be copied of the manuscript
', 3b' position is 3m-*3b VC in Figure 1
On the other hand, since it hardly moves, the central part 3C of the original is closed, so it is necessary to push the central part of the original downward while pulling the edges 3m' and 3b' of the original outward, which makes copying time-consuming. Multiply. Also, the center line 3d of the two open pages of the manuscript, and the leading edge 3a.

Since it is also difficult to accurately detect the position of the document 3b from the back side of the document, the copying position tends to be uneven. The present invention is primarily a document holding device for an electronic copying machine that solves the above two drawbacks by being added to a conventional copying machine.

An embodiment of the document holding device according to the present invention will be described below with reference to the accompanying drawings. .

FIGS. 3 to 7 show an outline of the configuration of a document holding device according to the present invention. FIG. 3 shows a side view of the apparatus of the present invention in a free state when it is mounted on a copying machine and no original is mounted. In FIG. 3, reference numeral 1 denotes the main body of the copying machine, 2 an original table made of a transparent glass plate on the upper surface thereof, 4 an original holding device of the present invention, and 5 a supporting portion thereof. An anchor bin 6 is fixed to the support part 5, and the anchor bin 6 is inserted into a hole 7 provided on the top surface of the copying machine to regulate the horizontal position of the support part 5.

A bracket 8 is fixed to the support part 5, and a bottle 9 is fixed to the bracket 8. A bearing 1.0 is coupled for rotation around the bin 9, and a bearing 10 is coupled to the left end of the U-shaped frame 11. A bracket 12 and a bottle 13 are fixed to the right end of the frame 11. A bearing 14 is coupled to the bin 13 so as to be able to rotate around the bin 13. The bearing 14 is coupled to the left end of a U-shaped frame 15, and the right end of the frame 15 is connected to a bracket 16, which further supports the bin. 17 is fixed.

A guide sealer 18 is coupled to the bottle 17 for rotation around the bottle 17, and the guide roller 18 is in surface contact with the copying machine. Reference numerals 19 and 20 are plates made of transparent tempered glass or plastic, each having a fold-back shape frame 11. and 15 and is fixed. Support part 5. Brackets 21 and 22 are fixed to the frame 11 and the bracket 21, respectively.
1. Holes 23 and 24 are provided at the upper ends of the transparent plates 19 and 22, and a coil spring 25 is attached to the six inch 23.24 hole.
The weight of the movable parts such as the transparent plate 19. and 20 in a bent position as shown in FIG. FIG. 4 is a top view of the apparatus of the present invention shown in FIG. 3, and FIG. 5 shows a state in which the opposing portions of the two transparent plates 1912G are pressed down against the force of the spring 25.

Next, the effects of the document holding device of the present invention will be explained.

First, the two transparent plates 19 of the device of the present invention located in the position shown in FIG.
．． On the 1st of 20, as shown in FIG. 6, the bound manuscript to be copied is opened and the page to be copied is placed on it. Next, manuscript 3
is pushed down against the force of the spring 25 shown in FIG. 3, and the apparatus of the present invention is placed in the state shown in FIG. There are 3
From a to 30 and from 3f to 3b are transparent plates 1
9, and 20, making it possible to make copies.

Furthermore, since the center 3d of the document is always set at a predetermined position, such as the center of the E-side glass of the copying machine, the positions of letters on each page of the copied material will not be uneven. Furthermore, as shown in FIG. 5, the central axis of the bottle 13 is located above the upper surfaces 19m and 20m of the two transparent plates 19.20, so the distance between the opposing ends 19b+20b of the 19120 is Since it increases as the position moves from the position shown in FIG. 3 to the position shown in FIG. 5, it has the effect of making it easier to open and copy the central part of the bound document.

When using the device of the present invention on a conventional copying machine, the length of the optical system increases by the thickness of the transparent plate 19 and frame 11, but experimental results show that there is almost no effect. has been confirmed. If necessary, the position of the lens, focal length, position of the reflector, etc. within the copying machine body may be adjusted or switched.Also, the glass plate 2 on the top of the copying machine may be stacked with two sheets, and the present invention may be When using the glass, there is a method of removing one sheet of glass, and there is also a method of moving the flat glass 2 downward by the thickness of the apparatus of the present invention.

In addition, by using the document holding device of the present invention,
It is possible to easily and accurately copy bound documents and books using a general-purpose electronic copying machine having a flat document table on the front side.
