Description

[Detailed Description of the Invention] (Industrial application field) The present invention relates to an automatic writing system for writing characters automatically with a writing instrument such as a writing pen. The present invention relates to a short fence positioning device that can be placed.

(Prior Art) Regarding a device for automatically drawing a character or the like using a conventional writing instrument, a patent application relating to a driving method of the writing instrument has been filed in 2-3.
As you can see, there is no prior art on paper.

(Problems to be solved by the invention) The present invention is a writing brush type automatic drawing device, and if the short fence placed on the paper table is not in an appropriate position because it is automatically drawn, the short fence In addition to improving the fact that it is not possible to draw at the desired position above, it is necessary to control the vertical direction of the carriage that supports the writing brush because it is a writing instrument that draws characters. This is to improve the fact that it is necessary to detect the undulation of the height of the placement surface, and the contoured portion that detects it will damage the surface finish of the sheet placement surface.

(Means for Solving the Problem) In the present invention, the characters are drawn centering on the central position on the paper placing table, and therefore the central position of the short fence can be made to coincide with the mark indicating the central position on the paper placing table. By placing the short fence frame in such a way that it can be drawn at an appropriate position on the short fence, the paper placing surface is located below the moving range of the tracing section that detects the undulation of the paper placing surface. An extremely thin sheet member for protection is placed to prevent scratches on the finish of the placement surface.

(Operation) The present invention is a paper placing table on which a sheet is placed, a carriage for grasping a brush on the paper placing table to control the movement in the front, rear, left, right and up and down directions, and a drive for moving the carriage in the front, rear, left, right and up and down directions And a storage device for storing and storing control data for controlling the movement of the driving device, a support plate for supporting the carriage and moving the upper surface of the sheet stacking table, and a lower tip provided on the support plate. And a short rail frame member provided with a tracing portion that is slidably contacted with the surface of the paper loading table, and a mark that is placed on the upper surface of the paper loading table and that matches a mark marked on the lower frame portion. A sheet member provided at a position of a frame piece which is slidably contacted with the profiled portion of the frame member is provided so that characters can be drawn beautifully at a desired position on the short fence without bending and the short fence frame member is provided. Seat section provided in It is characterized in that the material prevents scratches due to the tracing portion that detects the undulations of the unevenness of the upper surface of the sheet mounting table.

(Embodiment) The structure of an embodiment of the present invention will be described below. Reference numeral 1 is an automatic drawing device for holding a paper placing table 2, an operation panel portion 3, and a writing brush 4 so that they can be moved vertically. A carriage 6 incorporating a Z-direction pulse motor 5 for vertically moving the writing instrument and a support plate 7 for supporting the carriage.
Is an X-direction pulse motor 8 which is provided on the upper surface of the sheet mounting table 2 and is driven in the X (horizontal) direction, and Y which is perpendicular to the X-direction.
A Y-direction pulse motor 9 for driving in the (vertical) direction is provided, and an X-direction pulse motor 9 for moving the carriage in the XY direction is provided between the X- and Y-pulse motors and the carriage 6.
-Y drive mechanisms 10 and 11 are provided, and the carriage 6
A Z drive mechanism 12 for moving the gripping section in the Z direction is provided between the Z pulse motor 6 and the writing tool gripping section. Reference numeral 13 indicates a character or characters stored in a storage unit (ROM) 15 of a microcomputer 14 incorporated in the display unit and the characters selected by operating the keys on the operation panel 3 by operating the keys of the operation panel 3. The control data displayed on the display unit 13 is transmitted to the pulse motors 5, 8 and 9 via the driver circuit 16.

The control data for characters that are frequently selected is stored in the ROM 15, but the control data for characters that are infrequently stored is stored in the external storage unit 17, and therefore, when used, the character is mounted through the mounting opening 18 and selected.

A small hole is bored in a substantially central portion of the mounting table 2, and a central light emitting portion 22 composed of an LED or the like is provided in the small hole at a height that does not project above the table surface of the mounting table. The light emitting unit illuminates a short fence placed on the table from below.

In the automatic drawing device 1, a ▽ -shaped marking portion 25 is marked on the main body side wall portion 24 on the X-direction line passing through the central light emitting portion 22,
Further, the head side wall portion 26 of the carriage 6 has a marking portion 27 of a ▽ portion.
It is marked.

Reference numeral 23 denotes a tracing portion arranged so as to be in sliding contact with the upper surface of the sheet mounting table 2 of the supporting plate 7, and the height of the tip of the writing system writing instrument 4 held by the carriage 6 by the tracing portion is set to the mounting surface. Can always be kept at a constant height.

Reference numeral 28 denotes a short fence frame member, which is provided with a vertically long rectangular opening in the center thereof and is formed so as to substantially match the size of a short fence commercially available. The lower frame 29 of the short fence frame member 28 is provided with a mark 31 which is coded to the sign 30 marked on the sheet mounting table 2.

Further, the frame piece 32 which is slidably contacted with the profile portion 23 of the short fence frame member 28 is formed of a sheet member made of a synthetic resin material such as polycarbonate having substantially the same thickness as the short fence.

Since the present invention has the above-mentioned configuration, the short fence frame member 28 is placed on the sheet loading table 2, the lower frame 29 is aligned with the frame of the loading table 2, and the mark 31 of the lower frame 29 is attached to the loading table 2. Sign 30
If a short fence is placed in the central opening, the central position of the short fence and the central position of the mounting table 2 coincide with each other, and the vertical and horizontal directions of the short fence are placed without bending.

When the desired character is selected on the panel 3 and the drawing motion is started, the carriage 6 is driven back and forth and left and right by the control data read from the storage unit 15 or 17, and the writing system 4 is moved vertically. Is also driven so that it can be drawn at the desired position on the short fence.

The surface of the paper tray is painted and finished beautifully, but when the carriage 6 is driven forward, backward, leftward and rightward, the short fence frame member 28 is provided below the follower portion 23 provided on the carriage support plate 7. Since the sheet member 32 that is a part of
The sheet member 32 is prevented from being scratched by sliding contact, and yet the thickness of the sheet member 32 is very thin and substantially the same as the thickness of the short fence. Therefore, it is possible to omit the error in the vertical drive control data of the writing instrument 4 for writing. is there.

(Effect) Since the present invention has the above-described structure and operation, it is easy to position the short fence, and since the short fence frame member is provided with the sheet member, the surface of the paper tray is on the carriage side. Since it is possible to prevent scratches from the profiled portion, it is extremely effective in practice.
