Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small and simple copying machine that can easily print postcards and the like by sliding operations.

2. Description of the Related Art Small and simple copying machines are known that use heat-sensitive materials to easily plate-make and print letters, designs, etc. on postcards, pamphlets, etc. by thermal copying and stencil printing.

By the way, conventionally, this type of copying machine consists of a base and a pressure plate pivoted at the rear end of the base, and the original and original paper (thermal sheet) are placed on a mounting table made of an elastic material provided between the two. Alternatively, the base paper and the paper to be printed are superimposed and a handle provided at the front end of the press plate is pushed down and pressed to perform plate making or printing.

However, in this type of copying machine, the rotating shaft provided at one end of the press plate is fixed, so it is not possible to apply a uniform pressure force, and even if the pressure plate is designed to be uniform, for example, The disadvantage is that the structure is complicated, such as by providing a rocking plate.

Further, since the handle of the press plate is used to press down artificially from above, variations in the quality of printing etc. are likely to occur.

Furthermore, since it is necessary to open and close the press plate up and down each time printing is performed, it is difficult to operate, which is particularly harmful when placed on a desk and used while sitting on a chair. Further, space in the vertical direction must also be secured, and conventional copying machines of this type have various problems that need to be improved in terms of performance and ease of handling.

The present invention eliminates the above-mentioned problems, and provides a new small-sized simple copying machine in the field of this type of simple copying machine, which does not cause variations in printing, etc. no matter who uses it, and is extremely easy to handle. The purpose is to

In order to achieve such an object, the present invention mainly consists of a main body provided with a clamping means therein and an insertion opening formed therein, and a movable body that can be moved in and out of the main body from the insertion opening by, for example, a sliding operation. The movable base is equipped with an elastic base and a presser plate on which the original paper and the copy paper are placed, and the movable base is inserted into the clamping means and the base paper and the copy paper are pressed against each other to perform plate making, printing, etc. It is characterized by being able to perform various types of copying.

That is, the movable base 3 is disposed so as to be positioned at the center of the lower surface of the movable base 3 with the movable base 3 completely inserted into the bulge 5 .

On the other hand, in the movable table 3, the bottom of the pallet 3a forms a bulged bottom part 3c in which the inner rectangular part bulges downward, and the elastic table 12 is fitted into this bottom part 3c, and the lower surface of the bottom part 3c It is guided by a pair of left and right guide rails 11, 11. That is, as is clear from FIG. 6, the cross section of the guide rail 11 is formed by an outer rail 11a that guides the side surface of the bottom portion 3c and an inner rail 11b of relatively low height that guides the lower surface of the bottom portion 3c. The table 3 is placed on the guide rails 11, 11, and slides on the guide rails so that it can move in parallel into the bulge 5. In addition,
The guide rail has a protruding stopper 11 at its front end.
c to prevent the movable table 3 from falling out when pulled out, and its rear end extends a predetermined length into the bulge 5, and its upper end shape is shaped like the movable table 3 in the bulge 5. It is formed into a curved shape so that it can be pulled out smoothly.

Further, the holding plate 13 has a frame 15 attached to its periphery as shown in FIG. A pair of left and right brackets 17 are located at the bottom of the rear end.
17, and a pair of pins 18, 18 protruding from the inside of the pallet 3a are pivotally connected to the holes drilled in the brackets 17, 17, and the pins 1
Coil springs 19, 19 are attached to 8, 18 to urge the presser plate 13 upward.

On the other hand, the lamp house 4 is used during plate manufacturing, and is constructed in the shape of a box with a downward opening.A flash lamp 20 is attached to the upper end of the interior with a holder 20a, and a reflective surface provided on the entire inner wall allows the lamp house 4 to be opened downward. The configuration is such that a uniform light beam is emitted. In addition, this flash lamp 2
To supply power to the lamp house 4, each contact is provided at the fitting part of the lamp house 4 and the top plate 5a on the main body 2 side.
A switch 21 is provided on the main body 2 side, and this switch 21 is pressed at the rear end of the movable base 3 when the movable base 3 is completely inserted into the bulge 5. Configure it to turn on. Note that the main body 2 is provided with a battery case (not shown).

The configuration of the small-sized simple copying machine 1 according to the present invention has been described above, and now how to use it will be described.

First, when making a plate, move the moving table 3 as shown in Figure 3.
is pulled out from the insertion slot 6, and the original 22, which will become the base paper, is placed on the elastic table 12, and the presser plate 13 is
A heat-sensitive sheet 23, which serves as copy paper, is attached to the mounting piece 15a of the
Insert and hold. The arrangement relationship between these components is shown in FIG.

Then, when such setting is completed, the moving platform 3
If you grasp the handle 3b and slide it into the entrance/exit 6, the upper surface of the presser plate 13 will first come into contact with the tip of the protruding strip 9, and as the insertion progresses, the presser plate 1
3 automatically closes downward, and the rear end of the lower surface 3d of the bulging bottom portion 3c comes into contact with the upper end of the eccentric roller 8, or a little closer to the front, as shown in FIG. 7A. Then, by further inserting the movable table 3, the bottom part 3c lower surface 3
The roller 8 that is in frictional contact with d follows the rotation, and due to the action of the eccentric, the movable table 3 moves upward as shown in FIG. As shown in figure c, the movable table 3 is rotated by 180 degrees and is located at the uppermost position.

FIG. 4 shows a state in which the movable base 3 is completely inserted into the bulge 5. In this state, the movable base 3 is sandwiched between the eccentric roller 8 and the protrusion 9, and the elastic base 12 Due to this action, the original 22 and the heat-sensitive sheet 23 are pressed against each other, and since the eccentric roller 8 is located at the center of the lower surface of the moving table 3, a uniform pressing force is applied. At the same time, the switch 21 is turned on, so the flash lamp 20 emits light and plate making is performed. That is, the original 22 is drawn with a black pen containing carbon, and the heat-sensitive sheet 23 is made of a semi-transparent heat-sensitive resin film. So-called thermal copying is performed in which a hole along the black part is formed on the surface by melting and shrinking.

Next, the case of printing will be explained. In this case, the lamp house 4 is unnecessary and is removed from the main body 2 side. First, a desired printing ink is applied and colored on the upper surface of the heat-sensitive sheet 23', which is a base paper obtained by the above-described plate making, and then a transparent sheet (not shown) is superimposed on it, and is applied to the presser plate 13 in the same manner as in plate making. Set. On the other hand, a printing paper 24, which is a copying paper such as a postcard, pamphlet, or card, is placed on the elastic table 12, and the movable table 3 is completely inserted into the bulge 5 in the same manner as in the plate making process. For example, the heat-sensitive sheet 23' and the printing paper 24 are evenly pressed against each other, the ink passes through the holes in the heat-sensitive sheet 23', and an image is printed on the printing paper 24 along the holes. Therefore, by exchanging the printing paper and repeating the operation, printing can be performed one after another.

In the above embodiment, when the movable table 3 is inserted into the bulge 5, an eccentric roller is used as a means for pressing the base paper and the paper to be printed, etc.;
In addition, a mechanism may be provided that applies a certain pressing force after the moving table 3 is inserted into the bulge 5.
Generally, the main body 2 may be provided with a predetermined clamping means. Moreover, any changes in the shape, structure, etc. of each part that do not depart from the gist are permitted within the scope of the present invention.

As is clear from the above description, the small simple copying machine according to the present invention performs printing by a so-called sliding operation in which a mounting table for original paper, etc. is slid into the main body, so that it opens and closes up and down using a conventional rotating shaft at one end. Unlike those that use a pressure plate, it is possible to apply a uniform pressing force to the entire surface when pressing the base paper and the printing paper, etc., and this pressing force is not artificially applied, so plate making, Printing quality can be significantly improved, such as by preventing printing variations.

In addition, since it can be used by sliding, it is easy to secure a space for use, and it is easy to operate, making it possible to significantly improve handling.

Furthermore, it can be provided as a small and simple copying machine that has various features such as being relatively simple to configure and being implemented at low cost.
