Description

[Detailed description of the invention] [Industrial application field] The invention moves a casing to a desired portion of paper on a loading surface, controls a pen arm protruding from the casing by a controller, and holds the paper on the pen arm. The present invention relates to an automatic drawing machine that automatically draws patterns such as predetermined figures or characters on paper within a predetermined drawing range using recording elements.

[Conventional technology]

An automatic drawing machine is made compact in size so that the casing can be manually moved on the mounting surface, and the pen arm protruding from the casing is controlled on the mounting surface by a controller consisting of a computer.
It is disclosed in Japanese Patent Publication No. 57-42519 and Japanese Utility Model Application Publication No. 58-157697.

The pen arm holds a drawing pen, and as the pen arm moves, the drawing pen moves in the XY coordinate direction within a predetermined drawing range and comes into contact with or separates from the paper surface on the mounting surface. The elevation is controlled as follows. A scale is fixedly installed in front of the casing.

[Problem that the invention attempts to solve]

Operate the keyboard (input device) of the automatic drawing machine to input character drawing information and required commands to the controller, move the casing of the automatic drawing machine to the desired position of the paper on the placement surface, and place the paper on the paper. When drawing a character pattern on a paper, it is not known in which area on the paper the character pattern will be drawn. Therefore, the operator has no choice but to roughly estimate the drawing range of the characters, making it difficult to draw the character pattern accurately at a desired position on the paper.

The present invention aims to eliminate the above defects.

[Means to solve problems]

In order to achieve the above purpose, a casing 2a is movably placed on a placement surface, and the casing 2a
An arm 4 protrudes from the casing 2a and is driven by a drive device built into the casing 2a, and an input device 34.
a controller 32 that controls the drive device according to plotting information input from the controller 32, and moves the recording element 6 held on the arm 4 in the XY coordinate directions within a predetermined maximum plotting range with respect to the mounting surface. In the apparatus for drawing, the casing 2a is provided with a drawing range indicating member 28a for indicating on the mounting surface a drawing range 16a corresponding to the drawing information set by the input device 34; 30a
, and the members 28a, 30a are linked to a drive device driven by a controller.

[Effect]

In the above configuration, character information is input to the controller 32 by operating the keyboard (input device) 34.
Enter. Next, the casing 2a is placed on the paper on the placement surface in the vicinity of the drawing area, and the drawing range indicating members 28a and 30a instruct the drawing area. Casing 2 based on the drawing range in the vertical and width direction of the character pattern
a is moved to match the drawing range to the drawing area of the paper. Next, when the automatic drawing machine 2 is operated, the pen arm 4 is driven, and a character pattern is drawn by the recording element 6 in the vertical width area specified by the drawing range indicating members 28a and 30a of the paper. . When drawing two lines of character strings, these two lines of character strings are drawn. A region in the vertical and width directions is designated on the paper by the drawing range designating members 28a and 30a.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

2 is a small automatic drawing machine, and a box-shaped casing 2a is configured in a shape suitable for being placed on a placement surface such as a drawing board. An elongated opening is formed in the front surface of the casing 2a along the X-axis direction. Reference numeral 4 designates a pen arm, which includes a pulse motor 6 for moving in the X-axis direction and a pulse motor 8 for moving in the Y-axis direction, which are built into the casing 2a so as to move along the opening in the X-axis direction and in the Y-axis direction. It is linked to. Further, the pen arm 4 is linked to a solenoid 10 built in the casing 2a, which swings the pen arm 4 and drives the tip of the pen arm 4 up and down. A recording element 6 made of a commercially available hollow pen or the like is removably held at the tip of the pen arm 4.
Reference numeral 14 denotes a scale fixed to the lower surface of the casing 2a, on which indicators 18 and 20 are formed to indicate the positions of both ends in the horizontal direction, that is, on the X coordinate axis, of the maximum possible drawing range 16 of the recording element 12. There is.
Reference numerals 22 and 24 are pulse motors built in and fixed to the casing 2a, and a feed screw 2 is connected to the output shaft of these motors.
6 and 27 are connected. 28 and 30 are pipe-shaped arms arranged at both ends inside the casing 2 in parallel to the Y-axis rail (not shown) 12 of the automatic drawing machine main body 2, and can slide along the longitudinal direction. It is supported by the guide in a fixed and non-rotatable manner. The arms 28, 30
Nuts are fixed to the rear ends of the two, and the feed screws 26 and 28 are screwed into the nuts. When the feed screws 28, 28 rotate forward and backward, the arm 2
8 and 30 are configured to move in forward and backward directions along the longitudinal direction. The tip portions of the arms 28 and 30 protrude a predetermined length forward of the casing 2a from the front opening of the casing 2a, and the protruding portions are located near both ends of the maximum drawing range 16 of the recording element 12 in the X coordinate axis direction. It is located in Drawing range indicating members 28a and 30a made of protrusions are fixed at the tips of each of the arms 28 and 30, and the lower end edge 28a' of the indicating member 28a is the drawing area 1 on the paper.
6a, the upper edge of the indicating member 30a' indicates the lower end position of the drawing area 16a, and both indicating members 28a, 30a indicate the vertical width area in which the character pattern is drawn. It is configured. The motors 6, 8, 22, 24 and the solenoid 10 are connected by cords to an output device 32a of a controller 32, which may be an internal or external microcomputer. 34 is a keyboard or input device for inputting information such as characters and graphics and various commands to the controller 32, and is disposed on the upper surface of the casing 2a. A display section 36 is provided on the upper surface of the casing 2a.

Next, the operation of this embodiment will be explained. first,
Character designation information to be drawn on paper is input to the controller 32 by operating the keyboard 34. Based on this information, the controller 32 calls the character pattern coordinate data in the storage section and controls the pulse motors 22, 24 according to a program installed in advance.
drive each. By driving the pulse motors 22 and 24, the arms 28 and 30 are moved in the longitudinal direction, and the lower edge 28a of the instruction member 28a is moved to the upper end of the drawing area 16a set on the paper based on the character information and line number information of the controller 32. ′ match, the drive of the pulse motor 22 is stopped and the upper edge 30a′ of the instruction member 30a is aligned with the drawing area 16.
When the pulse motor 24
drive is stopped. Next, when the input device 34 is activated to put the automatic drawing machine into a drawing state, the controller 32 drives the pulse motors 6, 8 and the solenoid 10, and predetermined character information is drawn on the paper. As is clear from the above description, the operator can
The upper and lower ends of the drawing area 16a can be visually recognized. Therefore, the operator can accurately draw a character pattern at a desired position on a sheet of paper using the automatic drawing machine 2.

In addition, the arms 28, 30 and the feed screw 2
6, 28 are the drawing range indicating members 28a, 30
A supporting mechanism is configured to support movably in one axis (Y coordinate axis) direction, which is the direction of protrusion and retraction from the casing 2a.

〔effect〕

As described above, the present invention has the advantage that characters and graphic patterns can be accurately drawn at desired positions on paper because the drawing area by the recording elements can be visually recognized.
