Abstract

PURPOSE:To attain smooth copying by providing a cutter for copying paper near a discharge outlet of the copying paper and at the rear side in the moving direction of the copying paper. CONSTITUTION:The discharge outlet 16 of the copying paper 3 is surrounded by two faces in long and short directions, the long direction is formed at right angles to a carrying path 14 of the copying paper 3 and the short direction is formed in parallel with the carrying path 14 of the copying paper 3. After copying is finished, when the paper is cut off by using the cutter 21, the copying paper 3 is left in the short direction by the elasticity of the copying paper 3. That is, the length (l) in the long direction is longer than the length S in the short direction, then the length (t) being the subtraction of the S from the (l) is left at the outside of the copying machine 1. Thus, in applying the next copy, the operator draws out the copying paper 3 by picking up a start end 4 of the paper 3 at the outside of the copying machine 1 and the copying is attained smoothly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a small, lightweight, and portable copying machine.

BACKGROUND OF THE INVENTION In recent years, single-toner type plain paper copying machines have become mainstream, and a large number of them are on the market.In recent years, they have become increasingly smaller and lighter, and are increasingly being used for personal use.

That is, conventional copying machines use a 100 volt AC power source to create images on copy paper using the Carlson process.

Problems to be Solved by the Invention Since the conventional copying machines described above can only be used in places where power is available, battery-powered copying machines have been proposed. For this reason, roll paper was used, and it was necessary to cut the copy paper ejected from the copying machine with scissors or the like.

Means to solve the problem: At the bottom of the copying machine, there is an opening for reading the original, and a one-dimensional light is provided to illuminate the opening, and in the center of the copying machine, the original is imaged on an image sensor. It is equipped with a lens and an image sensor.

In addition, a roll of copy paper is placed at the top of the copy machine, and the copy paper passes through the printer, which is located at the rearmost end of the copy machine in the direction of movement of the copy machine. The copy paper is ejected from the rear of the lower part of the machine, and a cutter for cutting the copy paper is installed near the copy paper exit and behind the exit.

Function Since the present invention has the above-described configuration, copying can be performed by simply holding one end of the copy paper and moving the copy machine over the document, and when the copy paper is cut with a cutter, the leading edge of the copy paper will be cut by the copy machine. It protrudes a little more, making next use easier.

EXAMPLES The specific structure of the copying machine of the present invention will be explained below. FIG. 1 is a perspective view of the copying machine of the present invention during operation, and FIG. 2 is an enlarged perspective view of the main parts of the copying machine of the present invention, particularly showing the copy paper outlet in detail. FIG. 3(a) is a sectional view of its structure, and is a sectional view taken along line XX in FIG. 3(b). FIG. 3(b) is a YY cross-sectional view of FIG. 3(a). In these figures, 1 is a copying machine, 2 is a document to be copied, and inside the copying machine 1 is a roll of copy paper 3 (the starting end is 4), an opening 5, a lens 6, and , -dimensional image sensor -7 (for example, -charge coupled device in which photosensitive elements are arranged in a row)
A device such as a CCD is suitable. ), and a line-type printer 8 (for example, there are thermal head printers, inkjet printers, etc., but a thermal head printer is most suitable, and this embodiment will be described below using an example using a thermal head printer.)
, a platen 9 that supports copy paper 3 , and a linear light source 10 that illuminates original document 2 .

The main components of the copying machine of the present invention have been described above, and before a detailed explanation thereof, the operating method will first be explained. First, by manual operation, the copying machine 1 is placed on the original 2 to be copied. Next, turn on the power switch (not shown), take the starting edge 4 of the roll-shaped copy paper 3 out of the copy machine 1 as shown in FIG. While moving the machine 1 in parallel in the direction of the arrow A, the copy paper 3 is drawn out of the copy machine 1 in the direction of the arrow B to make copies.

At this time, the light from the light source 10 illuminates the original 2, and the reflected light is imaged from the aperture 5 through the lens 6 onto the one-dimensional image sensor 7 and read, and at the same time is sequentially copied by the line printer 8. Copied copy paper 3 is sent to copy machine 1
Exit in the direction of arrow B outside. Note that there is a control section between the -dimensional image sensor 7 and the line type printer 8 that processes the data read by the image sensor 7 and sends it to the printer 8, but it is not shown here. The synchronization of the feeding speed between the feeding of the original 2 and the feeding of the copy paper 3 is as follows.
By holding and fixing the starting edge 4 of the original 2 by hand, and moving the copying machine 1 in parallel in the direction of the arrow A, the copying paper 3 of a length equal to the moving distance of the copying machine 1 in the input direction is moved in the direction of the arrow B. They are brought out in such a way that they are able to synchronize with each other. By the above operations, the characters and figures of the original document 2 are copied onto the copy paper 3.

Next, the specific configuration of the copying machine of the present invention will be described below. Since portability is the most important feature of the copying machine of the present invention, it is absolutely necessary to make it small and lightweight. Furthermore, since it is necessary to carry it in a pocket or bag, it is desirable that the copying machine be as thin as possible, and if a part of the copying machine protrudes, it is inconvenient to carry it in a pocket or bag, so it is desirable that the shape of the copying machine be approximately rectangular. In order to meet the above requirements regarding the external shape, the copying machine of this embodiment has the following configuration.

First, an opening 5 for reading the original is provided at the bottom of the copying machine 1 in order to come into close contact with the original 2, and a linear light source 10 for illuminating the original 2 is provided here. . In order to downsize the copying machine 1, the light source 10 is used in this embodiment.
An LED array in which light emitting diodes are arranged in a row is used.

The characters and figures on the document 2 illuminated by the illumination 10 are displayed by the lens 6.
The image is formed on the image sensor 7 via the image sensor 7 and read optically. Therefore, no other parts must exist within the range 11 surrounded by the original 2, lens 6, and image sensor 7.

Furthermore, it is not convenient for the printer 8 to be located above the copying machine 1. In other words, when the printer 8 is placed above the copying machine 1 as shown in FIG. In order to function, the copying machine tries to rotate in the direction of the arrow, and the opening 5 tends to float away from the original 2.
Reading becomes incomplete. For the above reasons, the printer 8 is provided at the bottom of the copying machine 1.

The explanation will be given again using FIGS. 3a and 3s. For convenience of wiring, it is desirable to install the battery 12 near electrical components, and since it must not block the reading range 11, it is placed above the image sensor 7 as shown in the figure.

Also, the copy paper 3 can be used as a sheet of paper that has been cut out one by one, but if you are making a large amount of copies, it is best to use a roll of copy paper because it requires less effort and effort to load. In this case, it is desirable to arrange it at the top of the copying machine 1 as shown in the figure. A removable cover 13 made of synthetic resin is provided for easy attachment when supplying copy paper.

Copying machine 1 so that copy paper 3 is conveyed to printer 8
There is a transport path 14 from top to bottom at the rearmost position with respect to the moving direction of the paper, and a guide 15 separates the copy paper 3 from the battery 12, the image sensor 7, and the lens 6. Prevents paper from being damaged.

As for the printer 8, as shown in Figure 3, there is a platen 9 for bringing the copy paper 3 into close contact with the printer 8. Go out of aircraft 1. Here, 17 is a spring fixed to the platen 9 to move the copy paper 3 to the printer 8.
It is closely attached to. When loading copy paper 3,
Since the copy paper 3 must be passed between the printer 8 and the platen 9, the printer 8 is attached to the printer base 18 along with the printer base 18 to which the printer 8 is attached.
It has a structure that opens and closes around a fulcrum 19 as shown in FIG.

The operating method and basic configuration of the copying machine 1 have been described above, and now the copy paper cutter of the present invention will be described.

As shown in Figures 2 and 3, the printer base 1
8. Printer case 20 that rotates with printer 8
A cutter 21 is provided at the lower end of the discharge port 16, that is, at the rear of the discharge port 16. The tip of the cutter 21 is sharply pointed, and the cutter 21 can cut off the copy paper 3 after copying. The reason why the cutter 21 is provided at this position is that the copy paper 3 must not be cut during the copying operation of the copying machine 1, and the copy paper 3 must be easily cut off after copying. Furthermore, in order to prevent the copy paper 3 from being wasted as much as possible, the printer 8 is connected to the copy machine 1.
For the same reason, the cutter 21 is also provided as close to the outlet 16 of the copying machine 1 as possible.

FIG. 6 shows a state in which copy paper 3 is cut out using cutter 21. As shown in FIG.

The ejection port 16 of the copy paper 3 is surrounded by two sides, a long direction and a short direction, and the long direction refers to the part from the bending part 22 of the copy paper 3 to the cutter 21, and the length therebetween is 1. It is. In addition, the short direction means that the bent portion 2 of the copy paper 3
2 to the lower end of the discharge port 16, and the length therebetween is S. Here, the longitudinal direction is the conveyance path 14 of the copy paper 3.
It is configured at right angles to the copy paper 3 in the short direction.
It is configured parallel to the conveyance path 14 of.

After copying is completed, when the cutter 21 is used to cut out the copy paper 3, due to the elasticity of the copy paper 3, the cut copy paper 3 remains in the short direction as shown in FIG.

In other words, since the length l in the long direction is longer than the length S in the short direction, the copy paper 3 remains outside the copying machine 1 by a length t obtained by subtracting S from 1.

As a result, when making the next copy, the operator can pinch and pull out the leading edge 4 of the copy paper 3 that has come out of the copier 1, making the copying operation smoother. It has become possible to greatly improve the operability of the

FIGS. 7C and 7D show other embodiments of the invention. In other embodiments of FIGS. 7C and 7D, the cutter 2
This shows an example in which the tip of 1 is jagged. Here, Fig. 7S and Fig. 7d are both Fig. 7a and Fig. 7C.
FIG. According to this embodiment, the effect of cutting the copy paper 3 can be further improved compared to the above embodiment.

Effects of the Invention As described above, since the copying machine of the present invention is provided with a copy paper cutter near the copy paper outlet, it is possible to cut out a roll of copy paper, and the copy paper after being cut is not copied. Since a small amount remains outside the machine, it is now possible to pinch it and perform the next copy operation smoothly.
