BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reading scanner,
The present invention relates to an integral structure with a printer.

[0002]

2. Description of the Related Art In an office where office work is becoming more OA, various kinds of OA equipment are very crowded on the office desk, and there is a desire to put as many OA equipment on the office desk as possible. is there. However, since the space on the office desk is limited, only the minimum OA equipment can be placed on the desk. Conventionally, an image scanner used for a word processor, a personal computer, etc. has been an independent device. The image scanner is an indispensable device for inputting patterns such as manuscripts, photographs, drawings, etc. into a word processor, personal computer, etc. There was a problem that I could not put it in. On the other hand, when using a word processor at home, a handy type image scanner is generally used, but in this case, there is a problem that it is difficult to use because it traces on a picture or a photograph.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. A printer and a reading scanner used in a word processor or the like are integrally structured to make effective use of space and used. The purpose is to facilitate.

[0004]

In order to solve the above-mentioned problems, according to the present invention, in a printer for printing characters on a document by thermal transfer with a thermal head or an ink ribbon, a reading sensor is mounted parallel to the platen, and a paper feed is performed. Read the original sent by the roller.

[0005]

According to the above structure, a document, a drawing, etc. are inserted from the paper insertion port of the printer, and the document is read by the reading sensor installed parallel to the platen while feeding the document by the paper feed roller.

[0006]

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, a keyboard 2 is provided at the front of the word processor 1, and a display unit 3 also serving as a lid is provided above the keyboard 2.
Is rotatably supported. A printer 4 is provided at the rear part, and a paper guide 5 and a printer cover 6 are provided at the upper part of the printer 4 so as to be openable and closable. As shown in FIG. 2, the printer 4 has a structure in which a ribbon carrier 8 is placed on an upper portion of a drive unit 7 and is driven left and right by the drive unit 7. The original 9 is inserted into the guide 10, is fed by the paper feed roller 11 while being guided by the guide 10, and is fed to the outside via the ribbon carrier 8. On the other hand, a platen 12 is mounted at a position facing the ribbon carrier 8, and a reading sensor 13 is mounted below the platen 12. As shown in FIG. 3, the reading sensor 13 includes a light emitting unit 14 that emits light 16 having a width of the original document 9 and a line sensor 15 that converts one line of characters of the original document 9 illuminated by the light 16 into an electric signal. A reading sensor 13 is provided. Figure 4
As shown in FIG. 5, a print head 17 is fixed to the side of the ribbon carrier 8, and the print head 17 has a thermal head 18 for printing one line of characters as shown in FIG.
Is provided on the left side of the side portion, and has a light emitting portion 19 for irradiating the height of one character line and a sensor 20 for laterally reading the height of one character line.
Is provided on the right side of the light emitting unit 19. Then, as shown in FIG. 6, the protective case 21 includes the light emitting unit 19 and the sensor 20.
Is provided so as to cover the front surface of the. The front surface of the protective case 21 is transparent, and the upper and lower and right sides of the protective case 21 are structured to block light.

In the above structure, when the drawing or the like written on the original 9 is read into the word processor 1, the original 9 is inserted along the guide 10 and the paper feed key is operated to operate the paper feed roller 1.
1 rotates to feed the document 9 to the position of the reading sensor 13.
Therefore, the light emitting unit 14 irradiates the back surface of the original 9 with the light 16 and reflects the characters or the like to generate contrast light, which is the line sensor 1.
It is incident on 5 and is converted into an electric signal. When one line is read, the feed roller 11 is rotated to feed the document 9 by one line, and the second line is read in the same manner as above.
In this way, when the last line is read sequentially, the paper feed roller 11 discharges the document 9 to the outside and finishes the reading operation. In another embodiment, the thermal head 18, the light emitting unit 19 and the sensor 20 are incorporated in the print head 17, and when the drawing or the like written on the document 9 is read into the word processor 1, the document 9 is guided along the guide 10. When the paper feed roller 11 is inserted and the paper feed key is operated, the paper feed roller 11 rotates to feed the original 9 to the position of the ribbon carrier 8. Therefore, the printer 4 moves the ribbon carrier 8 from, for example, the left end to the right end of the original 9 while the light emitting unit 19 irradiates the original 9 with the light.
The light reflected by the drawing written on the surface of the is converted into contrast light, enters the sensor 20, and is converted into an electric signal. When the first line is read, the paper feed roller 11 rotates to feed the original 9 by one line, and the second line is read in the same manner as above. In this way, when the last line is read sequentially, the paper feed roller 11 discharges the document 9 to the outside, and the reading operation is completed. Further, when the above-mentioned reading work is performed, the characters can be printed on the original 9 by the thermal head 18 simultaneously with the reading.

[0008]

As described above, according to the present invention, since the reading sensor is provided under the platen to read the drawing of the manuscript or the like, the external reading device is not required and the space is not saved accordingly, so that the desk is effective. It has the advantage that it can be used.
