Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a reading device and a copying machine for inputting image information to a computer or the like.

2. Description of the Related Art Structures of Conventional Examples and Their Problems With the remarkable progress in electronics in recent years, light and compact figure and character reading devices that are convenient to carry have been developed. The structure of a conventional reading device is shown in FIG. 1, and the conventional structure will be explained.

In this figure, 1 is a reading device, and 2 is a document.The reading device 1 is placed on the second side of the document 2, and by tracing the top of the document, figures and characters are read. The internal structure of this reading device 1 is disclosed in Japanese Patent Publication No. 44-1003, Japanese Patent Publication No. 45-13858, and Japanese Patent Publication No. 57-18.
It is possible to obtain the same results as the copying machine and facsimile reading device shown in Publication No. 172, and a typical example thereof will be explained below with reference to FIG. A window 3 is provided at the bottom of the reading device 1, through which the original 2 is read, and an image is formed on a line-shaped image sensor 6 through a lens 4. A roller 6 is attached to the reading device e1 and rotates in the B direction as the reading device 1 moves in the A direction while contacting the original 2. A rotary encoder (not shown) for detecting the rotation of the roller 6 is attached to the end of the roller coaxially with the rotation axis of the roller 6. Each of these parts is surrounded on the top, side, and bottom surfaces by a case 8 made of synthetic resin or the like.

Now, the operation of the conventional example will be explained. The window 3 of the reading device 1 is pressed against the desired position of the document 2 to be read, and while the document 2 is fixed with one hand, the reading device 1 is moved in parallel in the direction of arrow A with the other hand. The figures and characters on the original 20 are read by the image sensor 5 through the window 3 and lens 4, and as the reading device 1 moves in parallel in the direction of the arrow A, the rotary encoder rotates under the rotation of the roller 6.
A movement 1' of the reading device 1 is detected. The read data and the data detected by the rotary encoder are synchronized by the control unit 7 and sent out of the reading device 1.

However, with the above configuration (d2, when reading a thick document such as a book or magazine as shown in Figure 2), 0
I couldn't read one letter, figure, etc. on the side of the original that was bound to 11 pages thick. In Figure 2, C is the letter 1
This is the range in which figures, etc. are drawn. Now, as shown in this figure, since the bottom part of the reading device 1 is thick, it is difficult to tell where the window 3 is located on the bottom.
It was extremely difficult. That is, a certain degree of skill is required to accurately press the window 3 of the reading device 1 to the position where reading of the document 2 starts, and if the pressing is inaccurate, the portion that needs to be read may not be read. There were many inconveniences such as sometimes not being read, or unnecessary parts being read. Furthermore, even when the reading device 1 is moved in parallel along the document 2 in the direction A, since the bottom portion of the reading device 1 is thick, it is difficult to see from outside the reading device 9 which position of the document 2 is being read. Therefore, it is extremely difficult to accurately move the reading device 1 in parallel along the desired reading range of the original 2. Due to the inaccuracy of this parallel movement, parts that need to be read may not be read, or parts that do not need to be read may be read, resulting in many inconveniences.

Next, the structure of another conventional copying machine is shown in FIG. 3, and the structure of the conventional copying machine will be explained.

In these figures, numeral 9 is a copying machine, and 2 is a manuscript.The copying machine 9 is placed at the bottom of the manuscript 2, and by tracing the soil, the figures and characters of the manuscript are read and copied. 1
0 is a roll of copy paper whose starting end 11 extends outside the copying machine 9 and is held and fixed by hand. A window 3 is provided at the bottom of the copying machine 9, through which the original 2 is read and imaged onto a line-shaped image sensor 6 through a 1/lens 4. 12 is a line type printer such as a thermal printer or an inkjet printer, and the read figures and characters are copied onto copy paper 10 by the printer 12.

Between the image sensor 6 and the printer 12, the data read by the image sensor 6 is processed and sent to the printer 1.
There is a control unit 7 that sends the data to the 2.

13 is a platen that supports copying, il 0; Each of these parts is a case 8 made of synthetic resin, etc., with ten sides.
Surrounded on the sides and bottom.

Now, the operation of the conventional example will be explained. Press the window 3 of the copying machine 9 against the desired copy position of the original 2, press and fix the starting end 11 of the copying machine 9 against the original 2 with one hand, and move the copying machine 9 in parallel in the direction of arrow A with the other hand. . As a result, manuscript 2
The figures and characters are read by an image sensor 6 through a 3° window lens 4, and the read data is immediately outputted to a printer 12 and copied onto copy paper 10. With the parallel movement of the copying machine 9 in the A direction, copying paper of the same length as the moving distance of the copying machine 9 is fed out toward the slot in the direction of the arrow, so that the feeding speeds of the original 2 and the copying paper 10 can be synchronized. .

However, with the above configuration, when copying a thick manuscript such as a book or magazine as shown in Figure 4, it is not possible to copy the figures, characters, etc. of the manuscript on the side bound with the thickness of the previous page 1. Ta. In FIG. 4, C indicates a range in which characters, figures, etc. are written. Furthermore, if the copying machine 12 is tilted for copying, the focus of the image sensor will shift, causing a shift in the density of the copy and degrading the quality of the finished copy. That's it, copy machine 9.
Because the bottom part of the copying machine 9 is thick, it is extremely difficult to press the window 3 of the copying machine 9 to the position where copying of the original 2 is to be started. That is, a certain degree of skill is required to accurately press the window 3 of the copying machine 9 to the position where copying of the original 2 begins.
If the pressing is inaccurate, there are many inconveniences, such as parts that need to be copied not being copied, or parts that do not need to be copied being erased. Also, the copying machine 9 is connected to the original 2
Since the bottom of the copying machine 9 is thick even when moving in parallel in the A direction along
It is extremely difficult to accurately move the copying machine 9 in parallel along the copying range. Due to the inaccuracy of this parallel movement, a necessary portion of the original 2 may not be copied, or an unnecessary portion of the original 2 may be copied, which is also inconvenient.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a reading device and a copying machine that are excellent in operability and do not require any training.

Structure of the Invention The present invention makes the shape of the outer case of a reading device and a copying machine thinner at the bottom than at the top, so that when reading and copying thick originals such as books and magazines, the side of the original that is bound can be easily folded. To provide a reading device and a copying machine with excellent operability, which can be easily operated by anyone to read characters, figures, etc. all the way to the end, and which requires no training.

DESCRIPTION OF EMBODIMENTS First, a first embodiment of a reading device of the present invention is shown in FIG. Each part indicated by a number from 1 to 8 is the same as the conventional example, so a description thereof will be omitted. What is different here is the lower side of the case 8, where the position where the original 2 is read is narrower.

With the above configuration, a book can be created as shown in Figure 6.

By the end of my life, I was able to read the letters and figures on the bound side of thick manuscripts, such as magazines, with ease. C indicates the range in which characters, figures, etc. are written. This makes it extremely easy to perform various tasks that were problems in the past. That is, the window 3 of the reading device 1 is
Since the lower part of the reading device 1 is thin, the position where the document 2 is to be read is easily visible outside the reading device 1, making it easier to press the document 2 to the position where reading begins.

In the above description, an example has been described in which the lower portions of both sides of the case 8 of the reading device 1 are made thinner, but it goes without saying that the same effect can be obtained even if only one side is made thinner. The external view of the second embodiment of the reading device in which only one side of the lower part is thinned is shown in Fig. 7.
As shown in the figure.

Next, a first embodiment of a copying machine according to the present invention is shown in FIG.

The parts indicated by numbers from 2 to 6 and from 7 to 13 are the same as in the conventional example. What is different here is that the lower side of the case 8 is thinner where the original 2 is read.

With the above configuration, a book can be created as shown in Figure 9.

Text and graphics on the bound side of thick manuscripts such as magazines can now be copied without difficulty. In FIG. 9, C indicates an area where characters, figures, etc. are peeled off. This has made the copying process extremely easy. That is, when starting copying, the window 3 of the copying machine 9 is
Since the lower part of the copying machine 9 is thin, the work of pressing the document 2 to the copying start position can be easily performed because the copying position of the original 2 can be easily seen from outside the copying machine 9. This eliminates all the troubles that occurred with conventional copying machines, such as parts that needed to be copied not being copied, and parts that did not need to be copied being copied.

In the above explanation, an example was given in which the lower portions of both sides of the case 8 of the copying machine 90 were made thinner, but it does not go without saying that the same effect can be obtained by making only one side thinner.

11 of the second embodiment of the copying machine in which only one side of the lower part is narrowed
,? , j The external view is shown in Fig. 10. In this case, the configuration of the copying machine 9 is the same as that of the conventional example, but the difference is that the lens 4 and the image sensor 5 are installed on the side of the case 8, and the opposite side is made thinner.

The present invention has been described above with respect to one embodiment of a reading device and a copying machine, and below, other embodiments of a reading device and a copying machine according to the present invention will be described.

Another embodiment of the reading device is shown in FIG.

In the example shown in this figure, instead of the conventional lens 40, glass fibers 14 are arranged in a row facing the window 3, and the read data is sent out of the reading device 1. ? In place of the conventional roller 6 and rotary encoder, there is a rack 16 that is manually fixed to the document 2 and a magnetic material that is pivotally supported at the bottom of the reader 1 and rotates by meshing with this rack. Binion 16
And hee.

It consists of a magnetic sensor 17 that faces the pinion 16 and detects the rotation of the pinion 16, and the data detected by the magnetic sensor 17 is sent out to the outside of the reading device 1. There is a line-shaped image sensor (not shown) at the other end of the glass fiber 14, and the original 20 figures and characters are imaged by the image sensor and the data read there and detected by the magnetic sensor 17. The data is synchronized by a control unit (not shown) outside the reading device 1. Further, each of these parts is made of resin or the like, and the L side, side surface, and bottom surface are four-folded with one base 8.

Further, as a modification of the embodiment shown in FIG. 6, an electric motor (not shown) is directly connected to the rotating shaft of the roller 6, and instead of manually moving the reading device 1, the rotation of the electric motor (/7'', It is clear that it is effective to provide a similar structure to the above for an electric reading device that runs on its own.

As explained above, the present invention improves the operability of various types of reading devices that read originals while tracing the ``-'' of the original, and also improves the operability of various types of reading devices that read originals while tracing the ``-'' of the original. This also improves the operability of this type of copying machine.

Effects of the Invention The present invention changes the shape of the reading portion of the document to another portion 138:
? By making the shape of 1 = thinner, it is possible to read and copy characters and figures on the side of the original with ease, and there are no problems with reading or copying quality.
It is possible to provide a reading device and a copying machine with excellent operability that can be easily operated by anyone and does not require any training.
