Abstract

PURPOSE:To attain the easiness of portability and handing by providing an image pickup section and a printer section in a single casing, moving the casing on an original for read scanning and supplying paper by a required quantity to a write head. CONSTITUTION:A slit 10 introducing reflected light from the surface of the original 9 by an external light is provided to the lower face of the front edge of a copying machine casing 8, the light of original is formed on the surface of an image pickup element 1 and read via an image forming lens 6 and the read data is inputted to a control section 2 including a CPU and a memory. A recording roll 4 is turned by using a rear side roller 5, the recording paper is written, the paper is written, the paper is fed to the write head 3 and a pulse generator 7 giving a pulse to the control section 2 is driven by using the roller 5. The control section 2 outputs one line's share of the data read by the image pickup element 1 to the write head 3 at every time when the pulse is received and is in standby state while keeping the data to itself when no pulse comes.

Description

TECHNICAL FIELD The present invention relates to a portable copying machine that is easy to carry and suitable for easily copying any part of a document at any location.

PRIOR ART It is often necessary to cut out and copy a part of a large document or drawing, and in such cases, it is possible to easily make small size copies without copying and cutting out using a normal stationary copying machine. It would be convenient to have a portable copy machine that can do this.

For this purpose, in Japanese Patent Publication No. 58-49910,
It has an imaging section using a diode array, CCD, etc., and a printer section using a thermal head, electrolytic head, etc., and these parts are placed opposite each other via a copy support plate that transmits magnetic force, and both or - They are made movable by holding opposing positions with provided magnets, and are moved over the imaging unit and original to read and scan, and the read image information signals are displayed on a copy support plate via an information transmission path. A handy copy has been disclosed in which a print of an original image is obtained by transmitting information to a print section on a print sheet and performing writing scanning. Although the image pickup section and the printer section of this proposed device are small, it requires a copy support plate larger than the size of copy paper, and the device as a whole is not very compact.

OBJECTS In view of the above-mentioned circumstances, it is an object of the present invention to provide a portable copying machine that is integrated into a single compact unit and is easy to carry and handle.

Structure In order to achieve the above-mentioned object, the present invention includes: an image pickup section having an image pickup device on which a document image is projected in a line; and a printer section having a writing head that writes on paper using the output of the image pickup device. The device is housed in a single casing, and is moved over the document to read and scan the document, and by the movement, feeds the required amount of paper to the writing head. Features.

Below, the real m-sequence of the present invention will be explained in detail based on the drawings.

FIG. 1 is a sectional view of a portable copying paper to which the present invention is applied. The copy paper casing 8 has an Il@ slightly wider than the paper width of the paper size (for example, about 10.5 m in the case of a copy machine whose purpose is to reproduce a range of about 1/4 of A4 size),
A slit 10 is provided on the lower surface of the front end over almost the entire width of the document 9 for introducing external light reflected from the surface of the document 9. The original light incident from the slit 10 is transmitted to the imaging lens 6
parallel to slit 10 through ゛
An image is formed on the surface of the image sensor 1, such as a COD line sensor or diode array, and is read.

That is, the imaging lens 6 and the imaging element 1 form an imaging section. Note that a light source for illuminating the original may be provided in the casing 8. Furthermore, when a 1-magnification sensor is used as the image pickup device, a 1-magnification imaging optical system such as a convergent light transmitter array can be used instead of the imaging lens 60. Is the data read by the image sensor l stored in the CPU, memory, etc.? Inclusion system? It will be manually operated by IJ Department 2.

Further, inside the casing 8, there is provided a writing head 3, such as a thermal head, an electrolytic head, etc., which operates upon input of data output from the control section 2, and a recording paper roll 4 loaded into the casing 8. 7'C and Ether Thermal Paper I A roll of paper such as thermal paper is pulled out and fed toward the writing head 3, and after printing is discharged from the paper discharge port 11 to the outside of the machine.

Rollers 5 are provided near the front and rear ends of the lower surface of the casing 8, respectively, and the rollers 5 roll into contact with the document surface 9 during reading. The rotation of the roller 5 on the rear side rotates the recording paper roll 4, and the recording paper is fed from the roll to the writing head 3, and the rotation of the roller 5 causes the Z sils generator to send pulses to the control unit 2. It is designed to rotate 72 times.

A handle (not shown) is attached to the casing 8.
When copying, hold this handle in your hand and push the area to be copied on the original 9 with the front and rear rollers 5 in contact with the original surface 9, and the reflected light from the original enters the lens 6 through the slit 10. An image is formed on the image sensor 1, read, and stored in the control unit 2.

The writing head 3 is the width of copy paper, and is it for one line?
If the recording paper can be written at once, the recording paper such as thermal paper may be fed to the writing head 3 at the same speed as the document scanning speed. In this case, the pulse generator 7
If the interval is set to correspond to one line interval of the pulse IOT head, the control unit 2 outputs the data read by the imaging element 1 to the writing head 3 at a rate of 1 line/degree every time it receives a noggle. If the pulse does not come, the data is held in ■J part 2 and it waits.

With the above operations, reading and writing can be synchronized without controlling the scanning speed.

If the writing head 3 is of the type that scans horizontally (main scanning), the head 2 must be moved horizontally by the rotation of the rollers 5, and when the head returns, the paper must be simultaneously fed by the number of lines to be written. No. In the case of a head that writes 8 dots at a time vertically (in the paper feed direction), data e' for 8 lines from image sensor 1 is
lfl in MJ Gobe 2? , t (1/per line)
8) Glucose portion of the pulse generator that generates Glucose)
After the head returns, 8 lines of data may be output as the head moves, and when returning after completing one-way scanning, the thermal paper may be sent out for 8 lines.

Is the flowchart in Figure 2 for one line? This shows the flow of the copying operation when using a write head that writes all at once. It reads data, waits for the noggles from the noggles generator, and when a nockles occurs, transfers 1947 minutes of data to the E head. Output, read the next data, and wait.

FIG. 3 is a block diagram of the control unit 2 in FIG.
Convert to binary data with
22. Also, RAM23 is 2 for 1 line.
It only needs to have a capacity that can hold value image data.

Effects As described above, according to the present invention, the entire copying device is housed in one casing and is packaged extremely compactly, making it easy to carry and handle, and all mechanical drives are controlled by the operator. Because it relies on the movement of the robot, it consumes less power and is also effective in saving energy.
