Description

[Detailed description of the invention] (Technical field of invention) The present invention relates to a handy type compact copying machine.

(Background of the Invention) Conventionally, in small hand-held copying machines that copy characters, figures, etc. on a document while moving over the document, a roll of heat-sensitive copy paper is used as copy paper to record the read image. By setting paper, special recording paper is used.

FIG. 7 shows an example of a conventional small-sized copying machine. First, as a reading mechanism, a light source 201 using an LED or the like is provided inside the copying machine body 21 to illuminate the original 22, and the light is reflected by the original 22. The light from the light source 201
02 and passes through the lens 203 to the image sensor 2.
04. Reference numeral 205 denotes a roller that is in contact with the original 22. The roller 205 rotates as the main body 21 moves in the direction of arrow A due to reading scanning. A detection mechanism is configured together with a rotary encoder or the like (not shown) that detects the amount.

On the other hand, a line-type thermal head 206 serves as a recording mechanism.
is provided opposite the platen 208, and pulls out the rolled thermal paper 207 from the discharge port 210 through the gap between the thermal head 206 and the platen 208, and the platen 208 is rotated by a motor (not shown) or the like. , the thermal paper 207 is sent out.

Further, 209 is a control unit, which includes a built-in memory for storing read image data, and controls each reading and recording operation of the copying machine.

Copying using such a conventional small-sized copying machine is, for example,
As shown in the figure, point the main body 21 placed on the document 22 with the arrow A.
Move in the direction of and scan the area you want to copy. At this time, the characters and figures on the document 22 are read as image signals by the image sensor 204 and stored in the memory of the control unit 209. The control unit 209 converts the image signal from the image sensor 204 into a binary or multivalued image every time the main body 21 moves by a certain amount detected by the rotation of the roller 205, and stores it in a built-in memory as image data. The above reading operation is repeated until all scanning of the range to be copied is completed.

On the other hand, copy recording on the thermal paper 207 is performed at the same time as the start of the reading operation or after the end of the reading, and the control unit 209 sends one line of image data from the built-in memory to the thermal head 206, and based on this image data. By driving the thermal head 206, one line of copy recording is performed on the thermal paper 207. When the copy recording for one line is completed, the platen 208 rotates by one line pitch, and in the same manner, copy recording for one line by driving the thermal head 206 and feeding by one line pitch by the platen 208 are repeated, and the copied thermal head 208 is rotated by one line pitch. The paper 207 is sent out from the outlet 210 of the main body 21. The copy recording ends when all the image data stored in the memory of the control unit 209 is copied onto the thermal paper 207.

(Problems to be Solved by the Invention) However, such conventional small-sized copying machines use roll-shaped thermal paper that has been shaped to a specific size as recording paper, making copying difficult. Manual work is required to paste the printed thermal paper onto a notebook or plain paper, edit it, and file it, and there is a problem in that it takes time and effort to compile the copied materials.

(Objective of the Invention) The present invention has been made in view of the above-mentioned problems in the prior art. To provide a small-sized copying machine which allows direct copying and recording to facilitate editing and filing.

(Summary of the Invention) In order to achieve this object, the present invention provides a reading means and a recording means in the main body of a portable copying machine, and when the main body is moved over the manuscript paper for reading scanning, the reading means reads the original document. Optically reads characters and figures on paper and stores them in memory,
After this reading, the image information stored in the memory is directly copied onto the recording paper by the recording means during copy scanning in which the main body is moved over a recording paper such as plain paper or a notebook.

(Embodiment) FIG. 1 is an explanatory diagram showing an embodiment of the internal mechanism of a small-sized copying machine according to the present invention in a document reading state.

First, the structure will be explained. Reference numeral 11 is the main body of the small copying machine, and the main body 11 has a size that allows it to be easily handled with one hand. A light source 101 such as an LED, for example, is provided inside the main body 11 to illuminate the original 12 through the reading window 100. An image is formed on the image sensor 104 through the image. 105 is manuscript 1
2, and rotates as the main body 11 moves during reading scanning when the main body 11 is placed on a document 12 as shown in the figure. The roller 105 is provided with a detection mechanism such as a rotary encoder that detects the amount of relative movement between the document 12 and the main body 11.

On the other hand, 106 is a line-shaped thermal head, which is attached so as to protrude under the pressure of a spring 107 from a recording window 112 that is opened on the surface opposite to the reading surface of the main body 11 where the reading window 100 is provided. ing. 108 is a roller that comes into contact with recording paper such as plain paper or a notebook during a copying operation, which will be explained later, and rotates as the main body 11 moves over the recording paper. A detection mechanism such as a rotary encoder for detecting the relative movement amount between the recording paper and the main body is provided. Reference numeral 109 denotes a transfer ribbon wound into a roll and set inside the main body 11.The tip of the transfer ribbon 109 comes into contact with the heat generating part of the thermal head 106 during the copying operation, and then is released from the main body 11 through the discharge port 110 of the main body 11. It is discharged to the outside.

Furthermore, 111 is a control unit for controlling the reading operation and recording operation of the copying machine, and includes a built-in memory for storing image data obtained from the image sensor 104.

Next, each reading and copying operation according to the embodiment shown in FIG. 1 will be explained.

First, in the reading operation, as shown in FIG.
2, with the reading window 100 facing down, and the main body 11 is moved in parallel, for example, in the six directions of arrows, to scan the range to be copied. At this time, the reflected light from the light source 101 reflected by the characters and figures on the document 12 forms an image on the image sensor 104 via the mirror 102 and the lens 103, and the control unit 111 controls the rollers as the main body 11 moves. 1
Every time the main body 11 moves by a certain amount based on the amount of movement of the main body 11 detected during the rotation of 05, the image signal from the image sensor 104 is subjected to signal processing such as binarization or multi-value processing, and then the image data is All the image data obtained in the copying range by scanning the main body 11 around the copying range is stored in the memory, and the reading operation is completed.

Next, the copying operation after reading is performed as shown in FIG.
The surface of the thermal head 106 from which the heat generating part protrudes is directed onto the recording paper 13 such as a notebook or plain paper. At this time, the thermal head 106 is pressed against the recording paper 13 via the transfer ribbon 109 by the spring 107. In this initial state where the thermal head 106 is pressed against the recording paper 13 via the transfer ribbon 109, the control unit 1
11 is a thermal head 1 that reads the first line of image data from among the image data stored in the memory by the reading operation.
06, the thermal head 106 is driven based on this image data, and the thermal head generates heat to thermally transfer the ink layer on the transfer ribbon 109 onto the recording paper 13, thereby copying the first line.

Next, one end C of the transfer ribbon 109 pulled out from the ejection window 110 of the main body 11 is pulled onto the recording paper 13 with a finger or a pin.
When the main body 11 is moved in parallel in the direction of arrow B while being pressed fixedly, the transfer ribbon 109 is pulled out from the main body 11. During the parallel movement of the main body 11 while pulling out the transfer ribbon 109, the amount of movement of the main body 11 is detected by the rotation of the roller 10B, and the control unit 111 controls the thermal head 106 every time the main body 11 moves by a certain amount. The thermal head 106 is driven by sending one line of image data one after another, and the image data stored in the memory is directly copied onto a recording paper 13 such as a notebook or plain paper by a reading operation.

FIG. 4 shows the state of copying due to the movement of the main body 11 in eight directions. A transfer ribbon 109 is drawn out from the main body 11, and in conjunction with the drawing out of the transfer ribbon 109, a copying operation of image data by the thermal head 106 is simultaneously performed.

When such a copying operation is completed, the transfer ribbon 109, which is fixedly pressed against the original 13 by the pin 113, is peeled off from the recording paper 13 as shown in FIG. A copy can be obtained directly onto the recording paper 13 such as the following.

As is clear from such reading and copying operations,
With the compact copying machine of the present invention, characters and figures read from any position on a document can be directly copied onto an appropriate location such as a notebook or plain paper, and the copying operation can be performed simultaneously with editing and filling of the copied content. can be done.

FIG. 6 is an explanatory diagram showing another embodiment of the present invention, in which the transfer ribbon 109a uses thermal paper as a base material and an ink layer is provided on the base material. It is characterized by

That is, in the case of a normal transfer ribbon that does not have thermal paper as a base material, during a copying operation as shown in FIG. In the embodiment shown in FIG. 6, the transfer ribbon 109a is made of thermal paper as a base material, so one end of the ribbon 109a is pressed against the recording paper 13 at the same time as the copying operation. The same characters and figures as those copied onto the recording paper 13 by transfer are thermally recorded on the upper surface of the transfer ribbon 109a pulled out from the transfer ribbon 109a. Copying can be done by

In the above embodiment, in order to better bring the thermal head 106 and the transfer ribbon 109 into close contact with each other, and to easily peel off the transfer ribbon stuck to the recording paper during the copying operation, Although the transferred transfer ribbon 109 is taken out to the outside through the discharge port 110 of the main body 11, there is no problem if it is taken out from the thermal head 106 as it is without passing through the discharge port 110.

(Effects of the Invention) As described above, according to the present invention, images such as characters and figures on a manuscript paper are optically transferred to a portable copying machine main body during reading scanning in which the main body is moved over the manuscript paper. The image information is provided with a reading means that reads the image information and stores it in the memory, and a recording means that directly copies the image information stored in the memory onto the recording paper during recording scanning in which the main body is moved over the recording paper such as a notebook or plain paper. There is no need for special recording paper such as thermal paper that is molded to a specific size in the copying machine for the scanned image, and copies can be recorded directly onto plain paper, notebooks, etc. in the desired position, making it easy to edit and file copies. Organizing work such as processing becomes extremely simple and easy, and the usability of the compact copying machine can be greatly improved.

By using a transfer ribbon that uses thermal paper as the base material, the state of the copy relative to the recording paper can be checked on the transfer ribbon even during the copying process, making it easy to discover copy errors. Therefore, the ease of handling of the compact copying machine can be further improved.
