Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a copying machine for copying visual information such as documents and drawings (hereinafter referred to as copying).

[0002]

[Prior Art]

 Conventionally, as a copier, light emitted from a light emitting device is applied to desired visual information of a copy original, and the reflected light is received by a light receiving device as optical information, and the optical information is machine information for operating a machine. In general, the structure is such that the contents of desired visual information of the original copy are carbon-injected and printed on copy paper by converting the data into a carbon-ejecting device using a conversion device and the machine information is input to the carbon-ejecting device. Is shown in FIG. 4 and will be described below with reference to FIG.

In the copying machine 101, a light emitting device 102, a light receiving device 104, a converting device 105, and a carbon 115 emitting device 106 are housed in a rectangular parallelepiped main body 109. The ceiling 110 of the main body 109 is made of a transparent material such as glass so that it can transmit light rays. The copying method by the copying machine 101 will be described below.

First, the copy original 103 is installed on the ceiling 110 so that the visual information to be copied faces the ceiling 110. While the copy original 103 is pressed from above by the pressing plate 108, the white light f 1 is emitted by the light emitting device 102 directed toward the ceiling 110 in the main body 109. The light f1 passes through the ceiling 110 and is illuminated by the visual information of the copy original 103.

Then, the light f1 is reflected by the copy original 103 to be reflected light f2, which is received by the light receiving device 104 as optical information. The optical information is then sent to the conversion device 105, where it is converted into machine information for operating the machine. This machine information is input to the carbon 115 injection device 106, and the content of the visual information of the copy original 103 is injection-printed on the copy paper 107 with carbon 115 and carried out of the main body 109.

[0006]

[Problems to be solved by the device]

 However, as shown in FIG. 5, when the copy original 103 ′ is a booklet that is thick and double-spread, such as an encyclopedia, there is a gap between the alignment section 111 of double-page spreads and the ceiling 110 of the copying machine 101 main body 109. Will be created. Therefore, the light radiated in the vicinity of the alignment portion 111 of the double-page spread is not accepted by the light receiving device as accurate reflected light, and as shown in FIG. The content 114 is unclear.

An object of the present invention is to solve the above problems and to provide a copier that can make a clear copy regardless of the shape of the copy original.

[0008]

[Means for Solving the Problems]

 The structure of the present invention is as follows.

The light emitting device and the light receiving device are housed in a thin plate-like case, and the carbon injection device is housed in a main body which is separate from the case.

[0010]

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 denotes a copying machine, which comprises a main body 9 and a case 8 separate from the main body 9.

The case 8 has a thin plate shape, and houses the light emitting device 2 and the light receiving device 4 inside. Further, since the one surface plate 10 of the case 8 is made of a transparent material such as glass, it can transmit light rays.

A conversion device 5 and a carbon 15 injection device 6 are housed in the main body 9, and the light receiving device 4 in the case 8 and the conversion device 5 in the main body 9 are connected by a cable cord 12. ing.

A copying method by the copying machine 1 will be described below with reference to FIG.

Reference numeral 3 is an original copy, which is a thick and spread booklet like an encyclopedia. First, the case 8 is inserted between the pages of the original copy 3 so that the visual information to be copied faces the one surface plate 10 of the case 8. Then, in the case 8, the white light F1 is emitted by the light emitting device 2 which is directed toward the one front plate 10. On the other hand, the light F1 passes through the front plate 10 and is applied to the visual information of the original copy 3.

Then, the light F1 is reflected by the copy original 3 to be reflected light F2, and the reflected light F2 passes through one surface plate 10 of the case 8 and is transmitted to the light receiving device 4 in the case 8 as optical information. Accepted. Then, the optical information is output from the light receiving device 4, passed through the cable cord 12 and sent to the converting device 5 in the main body 9 shown in FIG.

The optical information is converted by the conversion device 5 into machine information for operating the machine, the machine information is input to the carbon 15 injection device 6, and the contents of the visual information of the copy original 3 are copied to the copy paper 7. Then, carbon 15 injection printing is carried out, and it is carried out of the main body 9.

According to this method, as shown in FIG. 2, even when the copy original 3 is thick and has a double-spread booklet, such as an encyclopedia, the double-spread page and the one face plate 10 of the case 8 are closely attached to each other. Since it can be made, there is no gap between the two.

Therefore, the light F1 applied to the double-page spread is received by the light receiving device 4 as the accurate reflected light F2, and the finished copy is clear over the entire visual information range disclosed on the double-page spread.

According to the embodiment of the present invention, the light receiving device 4 in the case 8 and the converting device 5 in the main body 9 are connected by the cable cord 12, and the optical information is transmitted through the cable cord 12. However, a wireless transmitter (electromagnetic wave transmission device) is installed after the light receiving device 4 in the case 8, and a wireless receiver (electromagnetic wave reception device) is installed in front of the conversion device 5 in the main body 9 to transfer optical information to radio waves. If converted and communicated, so-called cordless implementation without using the cable cord 12 can be realized.

Further, the light emitting device 2 and the light receiving device 4 are installed only toward the one front plate 10 of the case 8. However, as shown in FIG. 3, both devices 2'4 'are added to the case 8. If the other front plate 10 'of 8'is also made of a transparent material and is installed in the direction of the other front plate 10', both double-page spreads of the original copy can be copied at the same time.

Further, as the size of the case 8, a plurality of cases such as A3 to B5 may be prepared according to the size of the desired visual information, and the case 8 may be replaced depending on the case. Further, if not only the light emitting device 2 and the light receiving device 4 but also the conversion device 5 is accommodated in the case 8, only the carbon 15 injection device 6 can be accommodated in the main body 9.

In order to more clearly describe the configuration of the present invention, each drawing is exaggerated, so that the dimensional relationship between each component of the copying machine 1 and the copy original 3, the light emitting device 2 and the light receiving device 2 are shown. The positional relationship of the device 4 is different from the actual product.

[0024]

[Effect of the device]

 As described above, according to the present invention, the light emitting device and the light receiving device are housed in the thin plate-like case, and the carbon injection device is housed in the body separate from the case. Therefore, the copy original is a thick and double-spread booklet. However, desired visual information can be clearly copied over the entire range.
