It consists of a composite dynamic slider 65 that slidably passes through both side wing portions 65a and 65b.

As shown in FIG. 1, the writing instrument mounting mechanism G has a bifurcated protrusion at the proximal end of a writing instrument mounting arm 67 connected to a mounting rod 66 that spans both ends over the entire length of a mounting recess 65c cut out at the center of the forward side of the synthetic dynamic slider 65. end 67
a, 67b are supported so as to be able to swing freely, while the tip of the writing instrument mounting arm 67 is supported by a restraining torsion spring 68 which is wound around the center of the mounting rod 66 and has one end locked to the synthetic movement slider 65 and the other end to the base end. The lodging behavior is always urged downward, and a writing instrument insertion hole 70 is provided at the other end for inserting a writing instrument and fixing it with a screw 69 from the side.

Reference numeral 71 in the figure denotes a raising/lowering action bar of the writing instrument mounting arm 67, which is rotatably supported at both ends between bearing blocks 72 and 73 opposed to the corner edge of the rectangular base plate 15, and is used to hold the operating lever 71a upright. As a result, the support of the writing instrument mounting arm 67 is released and the tip is moved downward by the elastic action of the torsion spring 68, and the writing instrument (not shown) is inserted into the writing instrument insertion hole 70.
Press the tip against the paper surface to take a writing position, and tilt the operating lever 71a back toward the corner side to support the writing instrument mounting arm 67 and hold it down to the torsion spring 68.
The tip of the writing instrument attachment arm 67 is raised against the elastic force of the writing instrument, and the tip of the writing instrument (not shown) inserted into the writing instrument insertion hole 70 is separated from the surface of the paper, etc., to take a standby position.

Since the present invention is configured as described above, the operation lever 71a of the undulating action bar 71 is operated before use for writing.
Set the writing instrument mounting arm 67 back with the tip raised, select the thickness of the pen tip and lead, and the type of writing instrument according to the thickness of the characters and writing style, and insert the writing instrument vertically into the writing instrument insertion hole 70 from above. The tip of the writing instrument is raised and fixed with a screw 69 so that it does not come into contact with the surface of the paper or the like.

Then, the head end knob 74 of the lateral magnification adjustment shaft 36 of the lateral resolution dynamic transmission pantograph mechanism D is held and rotated to move to the desired magnification position of the lateral magnification setting elongated hole 32a.

At that time, the horizontal magnification is adjusted and set according to the relational expression: y ₁ (variable)/x ₁ (variable) x z ₁ (fixed)/w ₁ (fixed).

In parallel with this, the head end knob 75 of the vertical magnification adjustment shaft 59 of the vertically disassembled dynamic transmission pantograph mechanism E is held and rotated to move to the desired magnification position of the vertical magnification setting elongated hole 56a.

Similarly, the vertical magnification is adjusted according to the relational expression: y ₂ (variable)/x ₂ (variable) x z ₂ (fixed)/w ₂ (fixed).

When writing italic characters, etc., loosen the head end knob 19a of the slope setting screw 19, align it with the angle scale 18a, and rotate the semicircular protractor plate 18 along the circular arc elongated hole 18b to set the chord side. By tightening the slope setting screw 19 to tilt the right and left desired angles, the screws 19 are superimposed and fixed to the connecting action plate 3, so that characters tilted to the left or right at a predetermined angle can be written.

After preparing in this way, write a writing utensil (not shown)
Place paper or the like under the copying needle 1 to determine the writing position, and hold the character pattern copying plate α with characters etched on the surface under the copying needle 1 in a holder (not shown). When the user stands vertically and releases the support of the writing instrument mounting arm 67 of the undulating action bar 71, the writing instrument mounting arm 67 moves downward due to the elastic force of the restraining torsion spring 68 and its own weight, and the tip of the writing instrument comes into contact with the surface of the paper.

Subsequently, press down the copying needle 1 to move the character pattern copying plate α.
If you trace along the character groove etc. engraved on the surface, the lateral movement transmission pantograph mechanism D will resolve only the lateral movement component of the trace of the following movement and adjust the lateral setting magnification and left/right inclination on the way. At the same time, the vertical resolution motion transmission pantograph mechanism E takes into account the vertical setting magnification midway through the division and interlocks only the vertical motion component, and the horizontal resolution motion transmission pantograph mechanism D and the vertical resolution pantograph mechanism D. This is a trace of the synthetic movement slider 65 of the synthetic movement reproducing mechanism F, which is installed across the guide rod 39 and the guide rod 62, which are the output parts of the dynamic transmission pantograph mechanism E, with the lateral setting magnification and the left and right setting inclination taken into account. The horizontal component motion and the vertical component motion of the tracing trace with the vertical setting magnification taken into account are recombined and reproduced.
A writing instrument attachment arm 67 attached integrally with the synthetic motion slider 65 follows and reproduces the movement of the synthetic motion slider 65, and draws on a paper surface etc. with a writing instrument attached to the tip. At that time, when you have finished writing one line that makes up a character, etc., move the operating lever 71a backwards, and when moving to the next line, operate the operating lever 71a to stand upright and bring the copying needle 1 to the next line. , repeat the same action again.

In this way, desired characters such as normal characters, long characters, plain characters, italic characters, etc. are written on the paper.

Here, excluding italic characters, regular characters, long characters,
Another embodiment of the present invention in which only plain letters are written will be described with reference to FIG. 5. The shape of the connecting action plate 3 in the above embodiment is changed by removing the semicircular protractor plate 18 and making the right side perpendicular to the front side. A guide elongated hole 3'b is directly extended through the connecting action plate 3' along the right side and extends at right angles to the guide elongated hole 3'c, and the interlocking adjustment rod 20 is inserted.
The structure is the same as that of the previous embodiment except that the other end is connected by a slide pin 30, and the same members are given the same reference numerals, and the operation thereof is also the same as that of the previous embodiment except for the slope setting operation.

Thus, in the present invention, the shape of the drawn characters can be changed not only to the original, but also to the long, flat, and if the slope setting mechanism C is provided, italic can also be freely changed by operating the knob, and the font can also be changed to Mincho, etc. It is possible to write by aligning the character pattern copying plates α, which are engraved with linear and alpha alphabet fonts, and by holding the character pattern copying plates α horizontally, you can write horizontally, and by holding them vertically, you can write vertically.

In addition, the present invention separates each element into vertical, horizontal, and slope components, and has an independent structure, so each element can be adjusted individually. Compared to other devices, this device has excellent practicality and other excellent effects.

The present invention allows you to write beautiful characters on any mechanical, electrical, architectural, surveying, etc. drawings, and can be used directly with ink to write on graphs, cards, posters, etc., as well as on film for drafting and film for overhead projectors. It has excellent effects, such as being able to write, use color ink, regardless of the size of the drawing or film, and also making it possible to write with a pencil, which was impossible with conventional devices.
