Description

[Detailed description of the invention] Industrial applications The present invention relates to a small-sized copying machine.

2. Description of the Related Art Conventional small-sized copying machines will be explained below using two examples.

9 to 11 respectively show a first conventional small-sized copying machine, with FIG. 9 being a side sectional view, FIG. 10 being a front sectional view, and FIG. 11 being a perspective view showing the state of use.

1 is the main body of the copying machine, and 2 is a document. An opening 3 is provided on the bottom surface of the main body 1 for reading image information of a document 2, and a transparent glass plate 4 is placed over the opening 3 so as to close the opening 3. Reference numeral 5 denotes an illumination means for illuminating the original 2, and L in which light emitting diodes (hereinafter abbreviated as LED) are arranged in a - column.
An ED array is used. Reference numeral 6 denotes a lens group having several lenses, which forms an image of the image information of the document 2 irradiated by the illumination means 5 on the image sensor 7 . The output signal of the image sensor 7 is processed by a circuit on the substrate 8 and sent to the thermal head 9. A platen 11 brings the thermal paper 10 into close contact with the thermal head 9. Furthermore, inside the body 1 of the copying machine, there is a rechargeable battery 12, an operation button 13, an operation button 1
A microswitch 14 interlocked with 3 is provided.

The first conventional compact copying machine is constructed as described above, and its operation will be explained below.

The opening 3 of the main body 1 is opposed to the original 2 to be read, one end 10a of the thermal paper IO is pressed against the original 2 with one hand, and the main body 1 is moved relative to the original 2 while pressing the operation button 13. Then, the illumination means 5 is turned on to illuminate the original 2, an image of the original 2 is formed on the image sensor 7 by the lens group, and image information of the original 2 is outputted from the image sensor 7. The image information data output from the image sensor 7 is applied to the thermal head 9, and the thermal head 9 heats the thermal paper 10 according to the image information. Through the above operations, the image of the original 2 is copied onto the thermal paper 10.

Next, a second conventional example will be explained. Here, the same parts as in the first conventional example explained above are given the same numbers and the explanation is omitted.

FIG. 12 is a side sectional view of a second conventional example of a small-sized copying machine. 30 is a cylindrical platen, and a pulley 31 is fixed to one end of the platen 30.

The pulley 31 is interlocked with a pulley 34 fixed to a driven roller 33 via a belt 32. The driven roller 33 is in contact with the outer surface of the roller 35 and is interlocked with the roller 35. Further, a part of the outer surface of the roller 35 is exposed from the main body 1.

The operation of the second conventional example having the above configuration will be explained below.

First, the main body 1 is placed on top of the original 2, and the main body 1 is held by hand and moved in the direction of arrow A. Then, the outer surface of the roller 35 comes into contact with the document 2, and the roller 35 rotates in the direction of arrow E. The driven roller 33 is rotationally driven by the roller 35,
Since rotational force is transmitted to the platen 30 by the belt 32, the platen 30 rotates in the direction of arrow F. As a result, the thermal paper 10 is driven in the direction of arrow B and is ejected from the main body 1. At this time, the image of the original 2 is focused on the image sensor 7 by the lens group 6, and the output signal of the image sensor 7 is applied to the thermal head 9.
The image is copied onto thermal paper 10. In other words, the roller 35
rotates, and the platen 31 feeds the thermal paper 10. Therefore, the thermal paper 10 is fed so as to have a specific relationship with the distance that the main body 1 has moved relative to the original 2.

Problems to be Solved by the Invention The first of the conventional copying machines described above has a simple structure, is small in size, and can be manufactured at low cost. It was necessary to move the main body with one hand, and both hands were required for copying operations.

Furthermore, since the copying operation is performed by sliding the main body over the original, if used by an unskilled user, the direction in which the main body is slid relative to the original will gradually deviate if the portion to be copied is long. There was a case.

Although the second conventional example allows copying to be performed with one hand, it has a complicated structure and is difficult to manufacture compactly and inexpensively.

Furthermore, if the rollers, driven rollers, boobies, or platens are not made with high precision, the distance the copying machine has moved relative to the document and the distance the thermal paper has been fed may not have a specific relationship. First, there is a problem in that a normal copy image may not be obtained.

The present invention solves the above-mentioned problems and provides a copying machine that has a simple structure and allows copying operations to be performed with one hand.

Means for Solving the Problems In order to achieve the above objects, the present invention includes an image reading means that reads an image of an original by moving relative to the original, and an image reading means that reads an image of an original by moving relative to the original; a printing means for providing image information; a roller mounted so that at least a portion thereof is exposed at a position facing the original; It is provided with a drawer opening for the copy medium to be placed.

Effects With the above configuration, the present invention presses the roller against the original through the copying medium, and when the main body is moved relative to the original, the roller rolls over the original through the copying paper, causing the contact between the copying medium and the original. Since there is a large sliding friction between the copy medium and the main body, and a small rolling friction between the copy medium and the main body, the copy medium is pulled out from the main body.

Embodiment FIGS. 1 to 5 show a first embodiment of the copying machine of the present invention. Here, the same numbers are given to the same parts as in the conventional example described above.

Reference numeral 1 denotes a main body of the copying machine, and an opening 3 is provided on the bottom surface of the main body, and a transparent glass plate 4 is attached so as to close this opening 3. 5 is an illumination means for illuminating the original 2, and is an LED
It uses an LED array arranged in a row. Reference numeral 6 denotes a lens group having several lenses, which forms an image of the image information of the document 2 irradiated by the illumination means 5 on the image sensor 7 . The output signal of the image sensor 7 is processed by a circuit on the substrate 8 and sent to the thermal head 9. A platen 11 brings the thermal paper 10 into close contact with the thermal head 9. Furthermore, inside the main body 1 of the copying machine there is a rechargeable battery 12 and an operation button 1.
3. A microswitch 14 interlocked with the operation button 13 is provided. Furthermore, the thermal head 9 is constructed as follows. That is, 15 is a fulcrum, and the head base 16 is pivotally supported on the main body 1 by this fulcrum 15, and the helad base 16 is provided with a hook 17. 18
A stopper is provided with a protruding pin 19 that locks a hook 17, and is slidable up and down with respect to the main body 1. Further, a guide plate for the thermal paper 10 is attached to the thermal head 9 via a support rubber 20, and the thermal head 9 is connected to a signal line by a terminal plate 21. 22 is a sprung plate, and together with a coil spring 23, the platen 11
is pressed against the thermal head 9. A roller 36 has a part of its outer periphery exposed from the lower surface of the main body 1, and is rotatably attached to the main body 1 by a roller shaft 37 and a bearing 38 that supports the roller shaft. Also, this roller 36
is made of a material with a high coefficient of friction such as rubber, and is thermal paper 10
It is made larger than the width l of. The copying machine of the present invention is constructed as described above, and its operation will be explained in detail below.

First, the stopper 18 is moved downward to release the engagement between the bin 19 and the hook 17, and the head base 16 is rotated about the fulcrum 15 to connect the platen 11 and the thermal head as shown in FIGS. 4 and 5. Open the space between you and 9. Pass the thermal paper 10 through the gap between the platen 11 and the thermal head 9, and then pass the thermal paper 10 through the gap between the roller 36 and the main body 1.
through it and pull out the thermal paper 10 from the main body. After that, move the head base 16 in the opposite direction to the fulcrum 15.
, the bottle 19 and the hook 17 are engaged with each other, and the platen 11 and the thermal head 9 are brought into close contact with each other with the thermal paper 10 interposed therebetween.

Next, hold the main body 1 of the copying machine of the present invention in your hand so that it faces the original 2, and while pressing the operation button 13, turn the main body 1 slightly downward so that the roller 36 is pressed against the original 2 via the thermal paper 10. Move it forward while holding it down. Then, a sliding frictional force acts between the thermal paper 10 and the document 2, and the thermal paper 10
A rolling friction force by the roller 36 acts between the thermal paper 10 and the main body 1 (the sliding friction force between the thermal paper 10 and the document 2
Since the rolling friction force between the thermal paper 10 and the main body 1 is much larger than the rolling friction force caused by the roller 36, the thermal paper 10 moves together with the original 2 relative to the main body 1. In other words, the thermal paper 10 moves in the direction of arrow B relative to the main body 1. Through the above operations, the illumination means 5 illuminates the original 2, the image of the original 2 passes through the aperture 3, is focused on the image sensor 7 by the lens group 6, and is read by the image sensor 7, and the output signal of the image sensor 7 is is applied to the thermal head 9. Then, the thermal head 9 heats the thermal paper 10 in accordance with the output signal of the image sensor 7, and the image of the original document 2 is copied onto the thermal paper 10.

During the above copying operation, the main body 1 moves while the roller 36 rolls over the original 2, so the main body 1 is always guided in a direction perpendicular to the roller shaft 37, and even when copying is performed over a long distance, the main body 1 moves. does not shift sideways. Furthermore, the main body 1 can be moved easily.

Furthermore, in addition to the above embodiments, as shown in FIG.
The diameter of both ends of 6 may be made thicker.

In this example, the length l of the small diameter portion of the roller 36 is
The relationship between the diameter φP of the large diameter portion, the diameter φQ of the small diameter portion, and the thickness t of the thermosensor 10 is set to satisfy the formula 0<(P-Q)/2<t. There is. moshi roller 3
The driven roller 39 at the position of the main body 1 opposite to the bearing 4
It is rotatably attached by 0. In other words, the roller 36 and the driven roller 39 are in a state of pressing each other,
Further, the thermal paper 10 is just fitted into the small diameter portion of the roller 36. In this embodiment, the thermal paper 10 is fed while being sandwiched between the roller 36 and the driven roller 39.
The longitudinal direction of the thermal paper 10 and the direction of the axis of the roller 36 are exactly perpendicular to each other, so that the thermal paper 10 will not be skewed during the copying operation.

Further, in this embodiment, the roller 36 is provided with a large diameter part and a small diameter part, but if the roller 36 is made of a somewhat soft material, the part of the roller 36 in contact with the thermal paper 10 will be recessed, and the large diameter part and the small diameter part will be recessed. The same effect can be obtained as when a section is provided.

Effects of the Invention The present invention provides an image reading means for reading an image of a document by moving relative to the document, a printing means for applying image information to a copy medium according to an output signal of the image reading means, and a position facing the document. A copying medium is provided with a roller mounted so that at least a portion thereof is exposed, and a copy medium draw-out port located opposite the original and in front of the roller with respect to the direction of movement relative to the original. Therefore, the simple structure allows copying to be performed with one hand, and even if an unskilled user uses the machine to copy long documents, the direction in which the main body slides will not deviate. Even without increasing accuracy, there is a specific relationship between the distance the copying machine body moves relative to the document and the distance the thermal paper is fed.
