Abstract

PURPOSE:To stably input picture data at high quality by incorporating a picture input device into a mainbody and automatically scanning data in an auxiliary scan direction. CONSTITUTION:A photoelectric conversion means 52 is arranged near a platen roller 51. A picture on an original fed by the platen roller 51 which rotates at constant speed by a driving control means is photoelectrically converted, and is outputted to a picture processing means. It picture-processes a signal obtained from the photoelectric conversion means 52 and transfers it to a storage means as picture data. The storage means stores picture data obtained from the picture processing means. The control means prints picture data read from the storage means on a paper 13 by a printing means 61 so as to output it. Thus, picture data can stably be inputted at high quality and it can be printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a document creation device equipped with an image input device for inputting images.

(Prior Art) Conventionally, some document creation devices such as word processors are equipped with an image input device for inputting images exclusively. However, since this image input device is usually provided separately from the main body, it has the drawback of increasing the cost of the device. Moreover, when inputting an image using this image input device, it is necessary to hold the image input device by hand and scan in the sub-scanning direction, which tends to cause distortion in the input image and also reduces the scanning speed. The disadvantage is that the image must be corrected in response to variations, making the circuit complex.

(Problems to be Solved by the Invention) As mentioned above, the image input device attached to the conventional document creation device is separate from the main body, which increases the cost of the device and also requires manual control of the sub-scanning direction. To scan
This method has disadvantages in that the image is easily distorted and a circuit for correcting the image in response to variations in scanning speed is required. Therefore, the present invention aims to eliminate the above-mentioned drawbacks, and has an image input device built into the main body and can automatically scan in the sub-scanning direction, thereby creating a document that can input image data stably and with high quality. The purpose is to provide equipment.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a document creation device having a printing means for printing while feeding a sheet of paper wound around a platen roller, in which the platen roller is moved at a constant speed. a drive control means for driving; a photoelectric conversion means for photoelectrically converting an image on a document sent by the platen roller, which is arranged close to the platen roller and rotated at a constant speed by the drive control means; and this photoelectric conversion means an image processing means for image processing a signal obtained from the image processing means to produce image data; a storage means for storing the image data obtained from the image processing means; and a printing means for printing the image data read from the storage means on paper by the printing means. and a control means for controlling the output.

(Function) In the document creation device of the present invention, the photoelectric conversion means is disposed close to the platen roller, and photoelectrically converts the image on the document sent by the platen roller rotating at a constant speed by the drive control means. Output to image processing means. The image processing means performs image processing on the signal obtained from the photoelectric conversion means and passes the image data to the storage means. The storage means stores image data obtained from the image processing means. The control means prints and outputs the image data read from the storage means on paper using the printing means.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the document creation device of the present invention. 1 is a main control unit that controls document creation, editing processing, image input processing, etc., 2 is a keyboard for manually inputting characters, etc., 3 is a display unit for displaying characters or images, etc., 4
A dictionary unit is referred to when converting a document input in hana to kanji; 5 is an image data reading unit that reads the image data; 6 is a printer unit that prints the created document and input image data on the record BM1; 7 is a platen roller drive control unit that drives and controls the platen roller built in the printing unit 6; 8 is a text data storage unit that stores text data of the created document; and 9 is input from the image data reading unit 5. An image data storage unit (for example, a bitmap memory) stores both data, and 10 is an external storage device such as a floppy disk device that stores programs, created documents, and the like.

FIG. 2 is a diagram showing an example of the mechanism of the image data reading section 5 and printer section 6 shown in FIG. 1. 11 is the main body of the document creation device; 51 is a platen roller that winds and feeds the paper 13;
2 is a sensor unit that photoelectrically converts and reads image information such as an image written on the paper 13; 61 is a printing unit that prints characters or images on the paper 13; 100 is an electronic component shown in FIG. It is a circuit board on which etc. are installed. Note that the printer section 6 includes a platen roller 51 and a printing section 61 as part of its configuration, and the image data reading section 5 includes a platen roller 51 and a printing section 61.
and a sensor section 52 are part of its configuration.

Next, the operation of this embodiment will be explained. When the operator inputs a character from the keyboard 2, the main control unit 1 converts it into a corresponding character code, reads out the text data from the text data storage unit 8, and displays it on the display unit 3.
to be displayed. When the operator who sees this display presses the kana-kanji conversion key on the keyboard 2, the main control unit 1 converts the corresponding segment into kana-kanji by referring to the dictionary unit 4, and stores it at the corresponding location in the text data storage unit 8. Writing progresses the creation of the document. At this time, if you want to input an image 1, insert the paper 13 on which the image data is written into the paper insertion slot of the document creation device main body 11, wrap a part of it around the platen roller 51, and then read the image using the keyboard 2. Press the key. Upon receiving this, the main control section 1 starts the platen roller drive control section 7 to drive the platen roller 5.
By rotating the paper 13S at a constant speed, the paper 13S is fed at a constant speed, and the signal input from the sensor section 52 through photoelectric conversion is converted into dot data and written into the image data storage section 9.

Thereafter, the operator edits the created document and the input image data, outputs it from the printer section 6, and creates a manuscript in which an image A and a character string opening are written, for example, as shown in FIG. I can do it.

According to this embodiment, the image data reading section 5 that reads the image
Since it is constructed using a part of the mechanism of the printer section 6, the device can be made inexpensive.

Further, since the image data reading section 5 can perform sub-scanning using the platen roller 51 and read the image data stably and at a constant speed, the quality of the image can be significantly improved without using an image correction circuit or the like.

[Effects of the Invention] As described above, according to the document creation device of the present invention, the image input device is built into the main body and can be automatically scanned in the sub-scanning direction, thereby stably inputting image data with high quality. be able to.
