Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting / supporting device for a paper feeder that supplies a large amount of cut sheets to a copying machine as an optional device of the copying machine.

Conventional Configuration and Problems There have been conventionally proposed various sheet feeding devices used as optional equipment for a copying machine, that is, various sheet feeding devices for supplying a large amount of cut sheets to a copying machine. There are roughly two types of methods for mounting on a copying machine. First, one method is a method of mechanically fixing the paper feeding device to a copying machine or a dedicated stand of the copying machine, and the other method is to make a convex portion of the paper feeding device in a concave portion of the paper feeding portion of the copying machine. It is a method of inserting and mounting. However, in the former method, when attaching and detaching the sheet feeding device to the copying machine, it is necessary for a specialized service person to use a tool, and the user cannot attach or detach as needed. In other words, even if you want to use a cassette that supplies a small amount of cut sheets, which is generally called a paper feed cassette, that is, if you want to use a cassette with a different cut sheet size, a serviceman must remove the large-capacity paper feeder and then install the cassette. was there. In addition, the copying machine also requires mounting hardware and the like, and in some cases the user has to purchase a dedicated stand, which in some cases imposes an excessive financial burden on the user.

In addition, the latter method does not have the drawbacks of the former, and although the paper feeding device can be easily attached to and detached from the copying machine, the weight of the paper feeding device and a large amount of cut sheets stacked in the paper feeding device causes the paper feeding of the copying machine. Since the load is applied to the part, the paper feeding part of the copying machine may be damaged in an extreme case unless the design is very large, and the operation may be hindered due to the subtle deformation. In particular, in the attached state, inconvenience is likely to occur when a part of the weight of a person bears by carelessly putting his / her hand on the paper feeding device.

The object of the present invention is to eliminate the drawbacks of the conventional examples as described above.
The purpose of the present invention is to allow it to be easily attached to and detached from the copying machine, and to prevent a load from acting on the paper feeding section of the copying machine. Still another object of the present invention is to provide a mounting and supporting device for a paper feeder which can be commonly used for a plurality of copying machines having different shapes.

Structure of the Invention: A dedicated stand for mounting a copying machine having a paper feed port and mounting legs on the bottoms of both sides thereof with a positioning plate that fits with the mounting leg interposed therebetween, and a pair of a pair of upper ends fixed to the positioning plate. A pillar member, a pair of fixing members for engaging and fixing the lower end portion of the pillar member and the lower end portion of the dedicated base, and one end fixed to the pillar member and the other end extending to the outside of the paper feed port. A horizontal rail having fixed floors and supporting legs whose height is adjustable, and means for supporting a paper feeder for supplying copy paper to the paper feed port to the horizontal rail so as to be movable in the extending direction. It is configured to have.

Description of Embodiments Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partially cutaway side view of a paper feeder mounting device according to the present invention. In the drawing, 1 is at least a copying machine.
It has one paper feed port 2 and a plurality of mounting legs 3 at the bottom. Four
Is a dedicated table on which the copying machine 1 is placed, and 5 is a paper feeding machine that accommodates a large amount of copying paper 6 inside. It is constructed so that it can be inserted and set in the mouth 2. Reference numeral 8 denotes a column member, and one end of the column member is movably fixed to the column member, and a horizontal rail 10 having a height adjustable support leg 9 at the other end constitutes a mounting support device.

Next, details of each configuration will be described.

The pillar member 8 is, as shown in FIG. 2, a first pillar member 11 and a second pillar member 12 which is fitted and slid below the pillar member 11.
The plate 13 is integrally formed or fixed with a screw 14 above one end. The plate 13 has a flat surface so that the lower surface abuts on the upper surface of the dedicated stand 4,
A protrusion member 16 that fits into a recess 15 formed in the mounting leg 3 of the copying machine 1 is provided on the upper portion. Although the concave-convex fitting structure is shown in the drawing, it is sufficient if the entire mounting leg 3 can be fitted or held and fixed instead of the projecting member 16 of the plate.

Further, as shown in FIG. 3, the bending pieces 13a, 13b are formed on both outer sides of the plate 13 so that the outer sides of the two mounting legs 3 can be regulated.
13b may be formed.

On the other hand, the other end of the pillar member 8, that is, the lower end of the second pillar member 12, is formed with an engagement piece 17 whose tip engages with the lower end portion of the dedicated stand 4, and fixes the pillar member to the dedicated stand 4. A fixing member 18 is provided. The detailed structure of this fixing member is shown in FIG.

The fixing bracket 18 with the engaging piece 17 formed at the tip is shown in FIG.
As shown in (b), it has a substantially U shape having two sides 18a, 18b, and the sides 18a, 18b are respectively inserted into the long holes 19a, 19b formed in the pressing plate 19 shown in FIG. The pillar member 12 is sandwiched and engaged with the lower end portion of the exclusive base. The pressing plate 19 is provided with a receiving seat 19c for the tightening screw 20 which is threaded through the fixing member 18. Therefore, when the tightening screw 20 is turned, the pressing plate 19 can press and fix the second column member 12 to the dedicated base 4 as shown in FIG. The long holes 19a and 19b of the pressing plate 19 prevent the two sides of the fixing bracket from expanding and also have a positioning function for the receiving seat 19c, which fixes the tip of the tightening screw 20 and prevents it from tilting. is doing.

One end of the horizontal rail 10 is supported by the first pillar member 11 at an angle.
It is fixed at 21. By making the mounting position of the support angle 21 variable, the position of the paper feeder can be adjusted. Further, as shown in FIG. 5, the horizontal rail 10 is composed of substantially U-shaped rails 10a and 10b facing each other. Traveling wheels 22 are provided on the paper feeder 5, and the traveling wheels 22 are provided inside the rails 10a and 10b, respectively, so that they can travel. At this time, the mounting shaft of the traveling wheel 22
If the rail 23 can be slidably contacted with the vertical pieces 10a ', 10b' of the rails 10a, 10b, traveling positioning can be performed. Reference numeral 24 is a flat plate on which the pair of rails 10a and 10b are fixed.

Further, as shown in FIG. 6, a stopper metal fitting 25 for the traveling wheel 22 having a chevron shape is provided at the other end of the horizontal rail 10, and when the paper feeder 5 is detached from the copying machine 1, It prevents the rail 10 from falling off. Running wheels at the same time
Since the stopper 22 is stopped and held using the top of the stopper fitting 25 or the top, the paper feed guide portion 7 of the paper feeder 1 is located below the paper feed port 2. Therefore, when a paper jam occurs, the jam process becomes easy. Reference numeral 26 is a height adjusting bolt for adjusting the height of the support leg 9.

The mounting device of the present embodiment has the above-described structure, and when a sheet feeding machine accommodating a large amount of copy sheets is mounted and used in the copying machine, first, one end of the two pillar members 8 is attached to the dedicated stand 4. The plate 13 fixedly attached to the copying machine 1 is placed according to the spacing between the placing legs of the copying machine 1. Then, the second pillar member 12 is slid to an appropriate position, and is pressed and fixed while being engaged with the lower end of the dedicated base 4 by the fixing member 18. Since the length of the column member 8 can be freely changed by the second column member 12 which fits and slides on the first column member 11, the column member 8 can be attached to various dedicated stands having different height dimensions.

In addition, in the case of a dedicated stand having a low height, the second pillar member 12
Without using the fixing member 18 and the pressing plate 19 directly to the first pillar member
11 and tightening screw while engaging with the lower end of the dedicated stand 4.
It may be pressed and fixed by 20. Further, when the height of the dedicated base 4 can be limitedly set within a certain range, the second pillar member 12 does not fit and slide on the first pillar member 11,
In order to simply extend the length of the first pillar member 11 downward,
It goes without saying that the second pillar member 12 may be fixed to the pillar member 11 with a screw or the like.

At this time, the horizontal rail 10 may be mounted beforehand or later, but the height is adjusted so that the paper feed guide portion 7 of the paper feed machine matches the paper feed opening 2 of the copying machine 1. I'll do it.
When the paper feeder is placed on the horizontal rail, the traveling wheels 22 are previously installed between the pair of rails to fix the position between the rails, or
After inserting it in the direction of arrow A shown in the figure, set it so that the stopper metal fitting 25 is attached. In this way, the copying machine 1
By mounting the mounting legs 3 on the plate 13 on the dedicated base 4 with their positions regulated, the paper feeder can be attached to the copying machine. In addition, a lock mechanism (not shown) is provided to prevent disengagement when mounted.

EFFECTS OF THE INVENTION As described in detail above, according to the present invention, since the pillar member can be slidably expanded and contracted so as to be press-contacted and fixed to the dedicated base, it can be applied to various dedicated bases having different sizes and can be mounted. Since the positioning can be performed in accordance with various copying machines, it is possible to obtain a great effect that the degree of freedom of adaptation is widened. In addition, when a mountain-shaped stopper metal fitting is provided at the rear end of the horizontal rail and the paper feeder is removed from the copying machine,
By diagonally stopping the rear part of the paper feeder while lifting it upwards, the paper feed guide part of the paper feeder can be moved downward from the vicinity of the paper feed port, and it is easy to remove jammed copy paper when a paper jam occurs. You can get the effect that you can do it. Further, since the height of the horizontal rails is adjustable to guide the paper feeding device, it is possible to mount and dismount the paper feeding device without affecting the paper feeding port of the copying machine. Many effects such as those described above can be obtained.
