BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a portable automatic painting machine which draws a picture by moving a movable arm having a writing implement at the tip thereof vertically and horizontally on a drawing screen.

[0002]

2. Description of the Related Art This type of portable automatic drawing machine is provided with a drawing machine main body provided with a key operation section for inputting characters and the like to be drawn and a display near a drawing position, and drawing with a writing tool attached to a tip end of a movable arm. And a portable pen plotter that moves the main body of the drawing machine to a position near the position when drawing at a position beyond the movable range of the movable arm.

[0003] In this manner, a small drawing area is easily drawn, which is different from a structure in which a whole drawing screen is drawn at a time like a large pen plotter. Similarly to the above, the writing implement is pulled up to a position not in contact with the drawing screen at all times, and is lowered during drawing so that the drawing end of the writing implement contacts the drawing screen. For this purpose, a pen holder for moving the writing implement up and down is provided at the tip of the movable arm.

[0004]

As described above, in drawing, it is necessary to position the main body of the actuator near the drawing position. In this case, unless the drawing machine main body is correctly positioned with respect to the drawing screen, accurate drawing at a desired position cannot be performed. Particularly, when characters and the like are drawn by drawing a table or a ruled line on the drawing screen in advance. In this case, there was a problem of displacement or the like.

[0005] A fixed scale for setting the position is usually provided on the drawing machine main body side. However, since the writing implement is located at the tip of a movable arm protruding from the drawing machine main body, the scale is grounded to the drawing screen of the writing implement. It was difficult to determine the position and the parallel state. For this reason, a shift in the drawing position cannot be avoided, and the above problem cannot be solved.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-described problems, and has as its object the purpose of making it easier to determine the grounding position and parallel state of a writing instrument, and to provide a portable instrument having a scale at a writing instrument portion capable of performing more accurate drawing. To provide an automatic painting machine.

[0007]

In order to achieve the above object, the present invention presupposes a portable automatic painting machine having a movable arm which supports a writing implement at a tip and can move vertically and horizontally on a screen. A scale was attached to the tip of the movable arm in parallel with the screen, had an opening that allowed the drawing end of the writing instrument to face the screen, and provided a scale displaying vertical and horizontal scale lines intersecting at the opening position. The present invention proposes a portable automatic painting machine having a scale at a writing implement portion characterized by the configuration.

[0008]

According to the portable automatic painting machine of the present invention having the above-described structure, the scale is provided at the writing implement part and moves with the writing implement, so that the moving position of the writing implement can be easily grasped. By providing the opening where the drawing end of the writing implement is located, and the vertical and horizontal graduation lines intersecting at the opening position, the scale is used as a target and the grounding position with respect to the drawing screen of the writing implement and the parallel state with, for example, a ruled line on the drawing screen Can be easily determined, and a quick and accurate drawing operation can be performed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a portable automatic picture machine according to the present invention; In FIG. 1, reference numeral 1 denotes a drawing machine main body of a portable automatic drawing machine, 2 denotes a keyboard provided on the main body 1 for inputting data to be drawn and drawing commands, and 3 denotes an LCD display. Reference numeral 4 denotes a scale fixed along one side edge of the main body 1.

Reference numeral 5 denotes a movable arm which protrudes from the main body 1 and has a pen holder 6 at a distal end portion 5a thereof. A base end portion is supported by a carriage 7 provided in the main body 1, and a drive motor (not shown) is provided. The driving mechanism includes the moving mechanism in the XX direction and the YY direction as indicated by arrows in the figure. A guide rail 8 guides the movable arm 5 in the YY direction. A writing instrument 10 such as a dedicated ink pen or a pencil lead holder is mounted on a writing instrument mounting portion 11 protruding from the side of the pen holder 6 and moves vertically and horizontally on a screen 12 on which the main body 1 is placed together with the movable arm 5. Is performed.

Reference numeral 13 denotes a scale according to the present invention.
2 in particular at the tip 5a of the movable arm 5 to which the "0" is attached.
And fixed as shown in FIG. That is, the scale 13 has one end of a mounting plate 16 fixed to a base 14 integrally provided on the upper surface thereof with screws 15, and the other end of the plate 16 is connected to the tip 5 of the movable arm 5.
In FIG. 7 (a), it is fixed to the front edge by a screw 17. In the attached state, the scale 13 has a slight gap from the screen 12 as shown in FIG.
It is parallel to 2. The material of the scale 13 is desirably a transparent acrylic resin or the like.

As shown in FIG. 3, the scale 13 has a shape extending from the tip 5a of the movable rail symmetrically to the left and right from the tip 5a, and one (left) of the scale 13 has a circular shape. An opening 18 is formed. The drawing end 10a of the writing implement 10 is located in the opening 18 so as to face the drawing screen 12, and the contact position P in contact with the drawing screen 12 corresponds to the center of the opening 18. And this opening 18
, Specifically, vertical and horizontal scale lines 19a and 19b that intersect at the contact point P in the opening 18 are displayed on the scale 13.

Accordingly, as shown in FIG. 1, when drawing is performed by the automatic drawing machine, for example, when it is desired to write a character or the like in accordance with the ruled line 12a on the drawing screen 12 on which the ruled line 12a is displayed, The parallel state with the ruled line 12a and the ground position P of the writing implement 10 can be accurately grasped by the scale lines 19a and 19b. As described above, the scale 13 serves as a target for accurately determining a drawing position in a drawing operation using the writing instrument 10, and thus the operation can be performed quickly and accurately. Therefore, the scale 13 is very convenient especially in a drawing operation in which a ruled line or a table is provided on the drawing screen and characters or the like are written in accordance with the ruled line or table.

In this embodiment, the scale 13 is fixed to the tip 5a of the movable arm 5.
In this case, the scale 13 is parallel to the drawing screen 12 with a slight gap.
There is no fear that the touch panel 3 touches the screen 12 and scratches it. However, in addition to this configuration, for example, the scale 13 is attached to the distal end portion 5a of the movable arm so as to be vertically movable, and the scale 13 is brought into contact with the drawing screen 12 when the position of the writing implement 10 is set before starting drawing. The scale 13 may be raised to a position where the scale 13 does not touch the screen 12 at the same time as the start of drawing. For this purpose, a mechanism for moving the scale 13 up and down is required. However, the pen holder 6 itself is configured to move up and down as shown by arrows for the up and down movement of the writing implement 10 as shown in FIG. It is also possible to use this vertical movement mechanism, and it can be easily embodied.

[0015]

As described above, according to the present invention, a scale that can be moved integrally with the movable rail is provided at the tip of the movable rail at the writing implement portion. Since the grounding position and the parallel state can be easily determined, even when a ruled line or a table is provided on the screen, quick and accurate drawing work can be performed by aligning the scale lines on the scale. The scale itself may be of a small size, does not impede the operation of the movable arm, has a simple structure, and has a small practical burden such as the addition of the scale. To play.
