DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a document reading device that can perform document reading processing and printing processing.

(Prior Art) Conventionally, in document reading devices such as image scanners that transport a document and read document information, there are some that are configured to print on the document. Printing was performed before the document was ejected, and the document was ejected after printing.

(Problem to be Solved by the Invention) In the above-mentioned conventional technology, after reading the document information, the document is conveyed to the print processing unit, and after printing is performed at the appropriate position on the document,
Manuscripts were being ejected. Therefore, time for reading the original, time for moving the original to the print processing section, time for printing, and time for discharging the paper are required, and the total processing time is long, which poses a problem in terms of work efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document reading device that can perform reading processing and printing processing, and can shorten the total processing time.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a document reading device having means for reading document information without transporting the document by raster scanning, in which the document is read simultaneously with the document information reading process. It is characterized by being configured so that printing can be performed on the surface, and further comprising a rotatable printing means for performing the printing, and furthermore, the printing means is movable in the main scanning direction. It is characterized by

(Function) According to the above-mentioned means, since the printing process can be performed on the surface of the document at the same time as the document information is read while the document is being conveyed, the processing time can be shortened.

Furthermore, by rotating the printing means, it is possible to change the orientation of the printed characters.

Furthermore, by moving the printing means in the main scanning direction,
It becomes possible to print at any position in the main scanning direction.

In the embodiment described above, the document reading method involves raster scanning the image information of the document placed on the contact glass 13 at the position of the document holding plate 14 by driving the reflecting mirror 16, and the document reading method in which the image information of the document placed on the contact glass 13 is scanned in a raster manner at the position of the document presser plate 14, and the sheet conveyed by the ADF 2. In both methods, the light source 15 is turned on by the light source driving device 26, and the reflected beam B after irradiating the document is transmitted by the reflecting mirror 16 and lens 17. After being led to the reading section 18 and photoelectrically converted, the image processing section 27 outputs image data.

When reading the image information while conveying the above-described sheet document using the ADF 2, the microprinter 12 can print on the surface of the sheet document.

That is, the sheet originals placed on the original document mounting table 4 are separated and conveyed one by one by the operations of the paper feed roller 5 and the separation conveyance section 6, and while being conveyed by the conveyance rollers 9, the document information reading means is read by the document reading section 7. 8, the document information reading process is performed. At the same time, printing processing is performed between the platen 11 and the microprinter 12 on the sheet document being transported by the transport rollers 9.

The microprinter 12 uses a type belt to perform printing, which will be described later, on a designated portion of a sheet document, and after the reading process and printing process are completed, the sheet document is discharged to the paper discharge tray 3 by a paper discharge roller IO. .

Control of each of these parts is performed by the CPU 23.

” The document reading device of the second embodiment has an interface 28.
．． It is connected to the host computer via the host computer 29, and in response to instructions from the host computer, reads the document information via the CPU 23, sends image data to the host computer, and when performing printing processing, prints characters and characters. The location is set in advance from the host computer.

FIG. 6 is a flowchart 1 of the printing operation of this embodiment. When a printing processing command is issued and the document reading processing operation starts, the first printing character to be printed on the printing belt is set in the microprinter 12. (Sl), and the first printing position on the document that is conveyed one line at a time for reading processing is determined by the micro printer 12.
The sensing processing unit 31 detects whether or not the part has been reached (S2), and if it is not yet at the predetermined position (No in S2),
The document is further conveyed by one line, and the line counter is incremented (S3). When the document is at the specified position (YES in S2), the platen 11 holds the document and the microprinter 12 Printing is performed (S4)
. Thereafter, the printing of the specified n characters is repeated in the same manner (S5), and as illustrated in Fig. 7, it is confirmed that the specified final printing character has been printed on the document (YES in S6), and after confirming whether the document information reading process has been completed, the document is ejected (S7).

The microprinter 12 is rotatable with respect to the same plane as the surface of the original as shown in FIG. Figure 9(a),
As illustrated in (b) and (c), it is possible to print by changing the orientation of the characters.

Furthermore, the carriage 12 is movable in the main scanning direction (direction perpendicular to the conveyance direction), and is driven by an appropriate motor 3 that receives a control signal based on the settings in the computer.
As illustrated in the explanatory diagram of FIG. 10, characters can be printed at the set positions (a) to (c) by the microprinter] 2.

(Effects of the Invention) As explained below, according to the present invention, since reading processing and printing processing can be performed simultaneously, processing time can be shortened, and the direction of the printed character and the printing position can be adjusted as appropriate. A document reading device that can be changed can be provided.
