Description

Detailed Description of the Invention [Technical Field] The present invention relates to a handy type manual copying device that manually scans an image reading means on a document during an image reading operation and manually scans a printing means on a transfer material during a printing operation. .

<Summary of the Invention> In summary, the manual copying apparatus according to the present invention is provided with a removably attached cover body provided with a conveying means for moving the roll-shaped transfer material in the scanning direction in contact with the printing section. The image can be reliably printed even on a transfer material whose width in the direction perpendicular to the width of the apparatus is smaller than the width of the main body of the apparatus.

<Prior art and its drawbacks> In general, copying machines using electrophotography require relatively large components such as a document table and a photoreceptor due to structural requirements, and there are limits to miniaturization and cost reduction of the device. be. Furthermore, since the transfer material is moved by a conveyance means composed of rollers, belts, etc., it is not possible to form an image on a very small transfer material due to problems in conveyance. For this reason, there have conventionally been manual copying apparatuses in which an image reading means and a printing means are provided in a portable main body, and the image reading means is manually scanned over a document during image reading work. Furthermore, there has been a manual copying apparatus in which a printing means is configured to manually scan a transfer material so that an image can be formed on any transfer material. This temporarily stores the image data of the document read by the image reading means in a memory, brings the printing means into contact with the transfer material, and moves the apparatus.

However, in the above-mentioned conventional manual copying apparatus, when scanning a transfer material, the main body of the apparatus is held with one hand and the apparatus is moved while holding down the transfer material with the other hand. For this reason, when an image is formed on a transfer material whose width in the direction perpendicular to the scanning direction is narrower than the width of the copying apparatus main body, the scanning performance is poor and the apparatus main body cannot be scanned in an appropriate direction. There were disadvantages in that the image was tilted or a part of it was missing, resulting in poor image formation.

<Object of the Invention> In view of the above-mentioned conventional drawbacks, an object of the present invention is to enable a transfer material having a small width in the direction perpendicular to the scanning direction to be brought into contact with a printing section and conveyed in the scanning direction. It is an object of the present invention to provide a manual copying device that can facilitate and reliably perform printing operations even when forming an image on an image, and can prevent deterioration of the image forming state.

<Structure and Effects of the Invention> The manual copying apparatus of the present invention includes a printing unit that prints an image read by the image reading unit on a transfer material, and during printing work, the printing unit is brought into contact with the transfer material and the printing unit is activated. A manual copying device that performs manual scanning is characterized in that it is provided with a detachable cover body that has a holding member that holds a roll-shaped transfer material and a conveying means that moves the roll-shaped transfer material in the scanning direction while bringing the roll-shaped transfer material into contact with a printing section. shall be.

With the above configuration, according to the present invention, when it is necessary to form an image on a small transfer material, the cover body is attached, and the roll-shaped transfer material included in the cover body is scanned while being brought into contact with the printing section. can move in the direction. At this time, an image can be formed on the transfer material by fixing the apparatus main body with one hand and moving the roll-shaped transfer material held on the apparatus side to the apparatus main body. Since the roll-shaped transfer material is held by the cover body, it does not move in a direction perpendicular to the apparatus main body, so that the apparatus main body does not tilt. Therefore, the image will not be tilted or parts will be missing.
It is possible to maintain a good image forming state.

<Embodiment> FIG. 1 is a side sectional view of a manual copying apparatus which is an embodiment of the present invention.

Inside the manual copying device main body 11, a light source 12, a lens 13, and a light receiving element 14 are provided near one end in the longitudinal direction. The lens 13 is made of a focusing light transmitting body, and the light receiving element 14 is made of a one-dimensional CCD sensor. The light from light source 12 is
It is exposed to the outside from la, and its reflected light is guided to the light receiving element 14 via lens 3. Further, the roller 15 is rotatably supported with a portion exposed to the outside. A driven roller 16 having a photo ink printer 17 is in contact with this roller 15 .

The above-mentioned parts constitute an image reading means, and during image reading work, move the main body 11 of the manual copying device onto the original 31 using the arrow F.
move in the direction. As a result, the light from the light source 12 scans the image on the original 31, and the reflected light is read by the light receiving element 14 and stored as image data in the memory of the control section. The manual copying device main body 11 moves in the direction of arrow F during image reading work.
When the roller 15 moves in the direction shown in FIG. As a result, the driven roller 1
6 rotates in the direction of arrow J. The photo ink printer 17 reads the rotational speed of the driven roller 16 and inputs it to the control section as speed data. A control unit (not shown) sets an area of the memory for storing image data based on speed data input from the photo ink printer.

A thermal head 21 is floatingly supported by a spring 22 near the other end of the main body 11 of the manual copying apparatus.

Further, an ink ribbon 25 is provided on reels 23 and 24 on a rack. The reel 24 is in contact with a roller 26 equipped with a photo ink printer 27, and the components that follow the rotation of the roller 26 constitute a printing means.
During printing work, the manual copying device main body 11 is moved in the direction of arrow G over the transfer material 41, as shown in FIG. When the manual copying apparatus main body 11 is set so that the printing means side contacts the transfer material 41, the thermal head 21 moves in the direction of arrow H due to the contact with the transfer material 41. This action generates an elastic force in the direction of arrow B in the spring 22,
The thermal head 21 and the transfer material 41 are connected to the ink ribbon 25.
Contact under constant pressing force through. When the manual copying device main body 11 is moved in the direction of arrow G in this state, the roller 2
6 rotates in the direction of arrow C due to contact with the transfer material 41, and the reel 24 driven by this rotates in the direction of arrow C. Therefore, the ink ribbon 25 is moved from the reel 23 to the reel 24.
As the manual copying device main body 11 moves in the direction of arrow G, a new ink ribbon always comes into contact with the transfer material 41.

The photo ink printer 27 detects the rotational speed of the roller 26, and the detection result is input as speed data to a control section (not shown). The control unit reads image data from the memory according to the manually input speed data, and controls the thermal head 21.
to drive. As a result, the ink of the ink ribbon 25 is thermally transferred to a position corresponding to the original image on the transfer material 41.

Note that a battery 18 provided approximately at the center of the manual copying apparatus main body 11 supplies power to the light source 12, the thermal head 21, and the microprocessor constituting the control section.

A cover body 1 is removably attached to the outer surface of the manual copying apparatus body 11 on the printing means side. There is a roller 3 inside this cover body l. A platen 4 and a paper guide 5 are provided. The roller 3 is provided at a position facing the roller 26 of the main body 11 of the manual copying device, and
is provided at a position facing the second thermal head. Furthermore, a roll paper 2 with a transfer material formed on the roll
is held rotatably. The transfer material 2a is in contact with the outside of the paper guide 5, and is exposed to the outside through the opening 1a via the platen 4 and roller 3. Among these, roll paper 2 is the roll-shaped transfer material of the present invention,
The roller 3 corresponds to a conveyance means.

3rd position and (B) are side sectional views of the cover body provided in the manual copying device.

On the inner surface of the cover body 1, there is a rotating shaft 3a of the conveying roller 3.
is rotatably supported. Further, the rotating shaft 3a passes through the end of the holding member 6. Thereby, the holding member 6 is rotatably attached to the cover body 1. A platen 4 is rotatably supported by the holding member 6, and a paper guide 5 is also formed. moreover,
A bearing 6a is formed near the center. Figure 3+B)
As shown in FIG. 2, the bearing 6a has a semicircular stepped portion formed at its end, and the shaft 2C of the roll paper 2 fits into this stepped portion.

A bearing 7 is attached to the inner surface of the cover body l at a position corresponding to the shaft 2c. This bearing 7 is made of an elastic resin material and is slightly deformed by the action of external stress. Further, a portion of the fitting portion 7a of the bearing 7 is open to the outside. As a result, when the holding member 6 is moved in the direction of the arrow from the state shown in FIG. 3 ([3), the shaft 2C of the roll paper 2 is inserted into the insertion portion 7a.

At this time, the lower end of the bearing 7 expands outward due to the pressure in the direction of the arrow {circle around (2)} by the shaft 2C. When the shaft 2C is inserted into the fitting part 7a, the lower end returns to its original state due to elastic force, and the shaft 2C
hold. As a result, the holding member 6 also stops in the state shown in the third position.

When forming an image on the roll paper 2 using the cover main body 1 configured as described above, the end portion 2 of the roll paper
b is exposed to the outside through the opening 1a, and then attached to the printing means side of the main body 11 of the manual copying apparatus as shown in FIG.

Drive data is output from the control section. Further, when the end portion 2b of the roll paper 2 is pulled out in the direction of the arrow A from this state, the roller 26 is rotated in the direction of the arrow C by the pressure of the conveyance roller 3. The photointerrupter 27 detects the rotation of the roller 26, and the detection result is input to the control section as speed data. The anti-prick section reads image data from the memory based on this speed data and drives the thermal head 2I. On the other hand, the reel 24 rotates in the direction of the arrow C following the rotation of the roller 26 in the direction of the arrow C. Therefore, the ink ribbon 25 is wound up from the reel 23 to the reel 24. Therefore, the roll paper 2 of the ink ribbon 25
The contact portion is constantly updated as the roll paper 2 moves in the direction of arrow A. When the end portion 2b of the roll paper 2 is pulled out in the direction of the arrow A, the roll paper 2 is in contact with the paper guide 5 over its entire width in the direction perpendicular to the direction of the arrow A. Therefore, the moving direction of the roll paper 2 is not tilted in the direction perpendicular to the direction of the arrow A, and the image forming state can always be maintained in a good condition. Further, when pulling out the roll paper 2, the manual copying apparatus main body 11 can be held with one hand and the roll paper 2 can be pulled out with the other hand, which makes the operation extremely easy.
