Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an original stocker structure for a copying machine having a cover that can be opened and closed.

<Prior Art> Conventionally, in a copying machine that has a cover that can be opened and closed, in order to use the top of the cover as a place to place unused or used manuscripts (original), etc.
In some cases, a stocker is provided on the cover to form a space for placing documents, etc. There were generally two types of structures for such stockers.

The first method is to determine the installation height of the stocker by considering the size and amount of documents to be placed, and place a plate-shaped stocker at a position above the cover that can secure an appropriate space for placing the document. This is the case when fixing the stocker.

The second method, in contrast to the first method described above, is to use a member equipped with a return means or a material with a return property such as a rubber disc, in order to cope with changes in thickness depending on the number of original sheets. This is when something is used as a stocker. That is, the document is held between the cover and the stocker.

<Problems to be solved by the invention> In the first case, the cover and the stocker form a space for placing a document and are separated from each other, so that the document can be easily inserted. However, when the cover is opened during use of the copying machine, there is a drawback that if the number of inserted originals is small, the originals are not held securely in the stocker and are likely to scatter.

On the other hand, in the case of the second type, the stocker presses down the document and holds it securely, so the above-mentioned drawback is overcome. However, since the stocker is always in contact with the cover, there is a drawback that it is difficult to insert the original.

The present invention solves the above problems and makes it possible to easily insert the original into the stocker when placing the original on the cover, and prevents the original from being held by the stocker and scattered even when the cover is opened. The purpose is to provide an original stocker structure for copiers that do not currently exist.

<Means for Solving the Problems> In order to solve the above-mentioned problems, the present invention aims to solve the above-mentioned problems. 1a is provided with an original cover 2 which can be freely opened and closed with respect to the main body 1, a stocker 3 is attached to the original cover 2 so as to be able to come into contact with and separate from the upper surface 2a of the original cover 2, and the stocker 3 is Contact direction M to the original cover 2
1, and for moving the stocker 3 in a direction M2 away from the original cover 2 against the urging means A when the original cover 2 is in the closed position. A moving means B is provided.

The moving means B includes a contact member 4 which is connected to the stocker 3 and protrudes vertically movably with respect to the back surface 2b of the cover, and a contact member 4 formed on the upper surface 1a of the main body 1 to close the original cover 2. and a push-up member 5 that abuts the abutment member 4 during posture.

<Function> In the present invention, the moving means B works when the original cover 2 is in the closed position. That is, the push-up material 5 formed on the main body 1 touches the abutment material 4 provided on the original cover 2.
and stocker 3 with original cover 2
The contact member 4 is pushed up in order to move it in the direction M2 of separation from the contact member 4. Then, the stocker 3 is separated from the upper surface 2a of the original cover to form a space between it and the original cover 2. Therefore, the manuscript C to space
can be easily inserted.

Further, when the original cover 2 is in the open position, the abutment member 4 and the push-up member 5 are separated and the moving means B is released. Here, the biasing means A acts on the stocker 3 in the direction M1 in which it contacts the original cover 2, causing the stocker 3 to contact the original cover 2. Then, the stocker 3 squeezes the original C inserted when the original cover is in the closed position and securely holds the original C between the original cover 2 and the original cover 2, thereby preventing the original C from scattering.

<Embodiments> The present invention will be described in detail below with reference to illustrated embodiments. FIG. 1 is a side view showing the original cover of a copying machine according to an embodiment of the present invention in the closed position;
This figure is a side view showing the original cover of the copying machine in an open position, and FIG. 3 is a plan view showing the original cover of the copying machine in a closed position.

As shown in the figure, in the present invention, a copying machine is provided with an original cover 2 for preventing light leakage in the form of a hollow rectangular plate that can be opened and closed on the top surface 1a of a box-shaped copying machine main body 1. A stocker 3 is attached to the original cover 2 so as to be able to come into contact with and separate from the upper surface 2a of the original cover 2. In addition, the stocker 3
A biasing means A is provided for biasing the stocker 3 in a direction M1 in contact with the original cover 2, and when the original cover 2 is in the closed position, the stocker 3 is pushed against the biasing means A so that the original cover 2 Moving means B for moving in the separation direction M2 from
will be provided.

The moving means B includes a contact member 4 which is connected to the stocker 3 and protrudes vertically movably with respect to the back surface 2b of the cover, and a contact member 4 formed on the upper surface 1a of the main body 1 to close the original cover 2. and a push-up member 5 that abuts the abutment member 4 during posture.

A pair of opening/closing plates 6 serving as hinges are provided on the left and right sides at the rear end of the upper surface 1a of the copying machine main body 1, and connect and support the original cover 2. Each opening/closing plate 6
A spring for buffering when the original cover 2 is opened and closed is installed inside.

A rectangular plate-shaped original cover cushion material 7 is connected to the back surface 2b of the original cover 2, and the main body top surface 1 is connected to the back surface of the cushion material 7.
A rectangular plate-shaped original holding sheet 8 is fixed to the document holding sheet 8, which is placed so as to be able to come into contact with and move away from the document a. Further, an installation space S is secured so that the moving means B does not interfere with both left and right end portions of the sheet 8 and the cushion material 7.

A pair of push-up members 5 of the moving means B are disposed at both left and right ends of the upper surface 1a of the main body under the original cover, and each of the push-up members 5 is provided in a trapezoidal shape projecting vertically upward from the upper surface 1a of the main body.

On the other hand, the abutment material 4 includes a contact plate 4a interposed between the push-up material 5 and the back surface 2b of the original cover when the original cover is in the closed position shown in FIG.
It consists of a small-diameter connecting cylinder 4b that is connected vertically upward from the rear end of a and that passes through the original cover 2 in a vertically movable manner and is connected to the stocker 3.
A plurality of connecting tubes 4b (four in this embodiment) are arranged at equal intervals in the left-right direction of the plate so as to prevent the document C from slipping. Further, the length of each connecting cylinder 4b is approximately twice the vertical width of the original cover 2. Note that a guide hole 2c is formed inside the original cover 2 and is fitted onto the connecting cylinder 4b.

The front part of the stocker 3 has a plurality of recesses 3a.
The connecting cylinders 4b of the rear end flat plate part 3c of the stocker 3 have an uneven shape in which convex parts 3b and convex parts 3b are formed alternately.
A connecting hole 9 is formed in each of the connecting portions, and a screw 10 is screwed into the connecting tube 4b through the connecting hole 9 to connect the stocker 3 and the abutment member 4.

Further, a tension spring 11 serving as the biasing means A is provided across the rear end flat plate portion 3c of the stocker 3 and the original cover 2. The spring pressure of the spring 11 is set so that the stocker 3 comes into contact with (including close to) the original cover 2 when the original cover is in the open position. Further, a spring storage groove 11a is formed in the holding portion of the spring 11 of the original cover 2 to store the contracted spring 11 when the original cover is in the closed position.

Note that 12 in the figure is an operating section.

In the above configuration, when the original cover is in the closed position shown in FIG.
The connecting tube 4b moves upward through the guide hole 2c of the original cover 2 in order to push it upward. Then, the stocker 3 is lifted and separated from the upper surface 2a of the original cover to form a space for placing the original. Therefore, when the original cover is in the closed position, the original C can be easily inserted from the front of the main body 1 (in the direction A in the figure).

Further, when the original cover is in the open position shown in FIG. 2, the contact plate 4a of the contact member 4 is separated from the push-up member 5.
Here, due to the biasing force of the spring 11, the connecting cylinder 4b of the contact member 4 moves down the outer fitting part 2c of the original cover 2, and the stocker 3 comes into contact with the upper surface 2a of the original cover. Therefore, since the stocker 3 presses down and securely holds the original C inserted during the closed position, the original C will not be scattered.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

For example, the biasing means is not limited to a spring as in the above embodiment, and may have other configurations. Also,
In the moving means of the above embodiment, the push-up member may be formed substantially flush with the upper surface of the main body by forming the abutting plate as the abutting member into a thick protruding shape. Furthermore, the shape of the stocker is not limited to the one having uneven portions as in the above embodiment, but it goes without saying that the stocker may be shaped like a flat plate with a small width from front to back.

<Effects of the invention> As is clear from the above explanation, according to the invention, when the original cover is in the closed position, the moving means works, the push-up material contacts the contact material, and the stocker is pushed up in the direction away from the original cover. Since the stocker is separated from the upper surface of the original cover to form a space, it is easy to insert the original into the space.
Further, when the original cover is in the open position, the abutting member and the push-up member are separated, the moving means is released, and the stocker is biased in the direction of contacting the original cover, thereby acting to bring the stocker into contact with the original cover. Therefore,
The document inserted when the original cover is in the closed position is tightly held between the stocker and the original cover, and the document can be prevented from scattering.
