[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a portable automatic drawing machine that draws an image by moving a movable arm, which has a writing instrument attached to its tip, vertically and horizontally on a screen.

[0002]

[Prior art]

 In this type of portable automatic drawing machine, the main body of the drawing machine equipped with the key operation part for inputting characters to be drawn and the display is placed near the drawing position, and the writing tool attached to the tip of the movable arm executes the drawing. This is a small portable pen plotter that moves the main body of the drawing machine near the position for drawing at a position beyond the movable range of the movable arm.

As described above, it is easy to draw an image in a small area, and unlike a large-sized pen plotter, which has a structure in which the entire drawing screen is drawn at one time, the writing method using a writing instrument is a large pen. Similar to the plotter, the writing tool is usually pulled up to a position where it does not come into contact with the drawing screen, and is lowered during drawing so that the drawing end of the writing tool comes into contact with the drawing screen. For this purpose, a pen holder for moving the writing instrument up and down is provided at the tip of the movable arm.

[0004]

[Problems to be solved by the device]

 As described above, it is necessary to position the actuator body near the drawing position for drawing. In this case, unless the main body of the drawing machine is accurately positioned with respect to the drawing screen, accurate drawing cannot be performed at the desired position. Especially, characters or the like are written on the drawing screen with a table or ruled lines in advance. In this case, the position shift or the like was a problem.

A fixed scale for normal position setting is provided on the main body of the drawing machine, but since the writing tool is located at the tip of the movable arm protruding from the main body of the drawing machine, the scale of the writing tool does not work on the scale. It was difficult to determine the grounding position and the parallel state with respect to the screen. Therefore, the shift of the printing position is unavoidable, and the above problem cannot be solved.

Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a scale on a writing instrument part that can more easily establish a grounding position and a parallel state of the writing instrument and can perform more accurate drawing. To provide a portable automatic drawing machine.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is based on the premise of a portable automatic drawing machine which has a movable arm that supports a writing instrument at the distal end and can move vertically and horizontally on the screen, and is provided at the distal end of the movable arm. In the writing instrument part, which is attached in parallel with the drawing screen, has an opening that exposes the drawing end of the writing tool on the drawing screen, and is provided with a scale that displays vertical and horizontal scale lines intersecting at the opening position. It proposes a portable automatic drawing machine equipped with a scale.

[0008]

[Action]

 According to the portable automatic drawing machine of the present invention having the above structure, since the scale is provided on the writing instrument part and moves together with the writing instrument, the moving position of the writing instrument can be easily grasped and the writing instrument can be placed on the scale. By providing an opening where the drawing end is located and vertical and horizontal scale lines that intersect at the opening position, it is easy to set the scale as a target and make it parallel to the grounding position of the writing tool with respect to the drawing screen and the ruled line on the drawing screen. Therefore, it is possible to perform quick and accurate drawing work.

【Example】

 An embodiment of a portable automatic drawing machine of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 is a main body of a portable automatic drawing machine, 2 is a keyboard for inputting data to be drawn and a drawing command input provided on the main body 1, and 3 is an LCD display. Reference numeral 4 is a scale fixed along one side edge of the main body 1.

Reference numeral 5 denotes a movable arm which projects from the main body 1 and has a pen holder 6 at its tip 5 a. The base end of the movable arm is supported by a carriage 7 provided in the main body 1, and a drive motor (not shown) is provided. By the driving mechanism including it, it is possible to move in the X-X direction and the Y-Y direction as shown by the arrow in the figure. Reference numeral 8 is a guide rail for guiding the movable arm 5 in the YY direction. A writing instrument 10 such as a dedicated ink pen or a pencil lead holder is attached to a writing instrument attachment portion 11 projecting from a side portion of the pen holder 6, and is vertically and horizontally arranged on a screen 12 on which the main body 1 is placed together with the movable arm 5. It moves and draws images.

Reference numeral 13 denotes a scale according to the present invention, which is attached and fixed to the front end portion 5a of the movable arm 5 to which the writing instrument 10 is attached, particularly as shown in FIGS. That is, in the scale 13, one end of an attachment plate 16 is fixed to a base 14 integrally provided on the upper surface thereof with a screw 15, and the other end of the plate 16 is at the front end edge of the tip portion 5 a of the movable arm 5. It is fixed by screws 17. In the mounted state, the scale 13 is parallel to the work screen 12 with a slight gap as shown in FIG. The material of the scale 13 is preferably transparent acrylic resin or the like.

As shown in FIG. 3, the scale 13 has a shape extending symmetrically from the front end portion 5a of the movable rail to the left and right of the front end portion 5a, and one of them (left side) has a circular shape. The opening 18 is formed. The drawing end 10 a of the writing instrument 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 exactly to the center of the opening 18. The vertical and horizontal scale lines 19a and 19b intersecting at the position of the opening 18, more specifically, at the contact point P in the opening 18, are displayed on the scale 13.

Therefore, as shown in FIG. 1, when performing drawing by the automatic drawing machine, for example, when it is desired to write a character or the like in line with the ruled line 12a on the drawing screen 12 in which the ruled line 12a is displayed, on the scale 13 By the scale lines 19a and 19b, it is possible to accurately grasp the grounding position P of the writing instrument 10 in parallel with the ruled line 12a. In this way, the scale 13 serves as a target for accurately determining the drawing position in the drawing work by the writing instrument 10, and thus the work can be performed quickly and accurately. Therefore, the scale 13 is extremely convenient particularly in the drawing operation in which the ruled lines and the table are provided on the drawing screen and the characters and the like are written in accordance with the ruled lines and the 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, and there is no fear that the scale 13 will come into contact with the drawing screen 12 and scratch it during drawing. However, in addition to this configuration, for example, the scale 13 is attached to the tip 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 instrument 10 is set before the start of drawing. It is also possible to lower the scale to a position and raise the scale 13 to a position where the scale 13 is not touched at the same time as the start of image formation. For this purpose, a mechanism for moving the scale 13 up and down is required, but the pen holder 6 itself moves up and down as shown by the arrow for the up and down movement of the writing instrument 10 as shown in FIG. Therefore, it is also possible to use this vertical movement mechanism, and it can be easily embodied.

[0015]

[Effect of device]

 As described above, according to the present invention, since the scale that can move integrally with the movable rail is provided at the tip of the movable rail in the writing instrument part, the grounding position and the parallel state with respect to the screen of the writing instrument with the scale as a target are set. Since it is possible to easily determine, even if a ruled line or table is provided on the drawing screen, it is possible to perform a quick and accurate drawing work by combining the scale lines on the scale. The scale itself may be small in size, has a simple structure and does not hinder the operation of the movable arm, and the burden of adding the scale is small. Is played.
