Description

[Detailed description of the invention] [Industrial application field] In the invention, a casing is placed at a desired position on a paper on a placing surface, and a writing instrument support arm protruding from the casing is moved in a XY axis and a Z axis direction by a controller. The present invention relates to an automatic imager that automatically draws desired characters, symbol figures, and the like within a predetermined range on a sheet of paper by a writing instrument controlled and held by the support arm.

[Conventional technology]

As shown in FIG. 6, a cursor mounting portion 2a is integrally formed on a writing instrument support arm 2 as disclosed in Japanese Utility Model Laid-Open Publication No. 1-148392. The mounting portion 2a and the mounting plate 4 fixed to the writing instrument support arm 2 are rotatably supported directly on the Y cursor 6 by pivot shafts 8,10. The Y cursor 6 is movably supported in the XY direction by an XY guide mechanism in the casing. By moving the Y cursor 6 in the XY direction and rotating the writing tool support arm 2 with respect to the Y cursor 6, the writing tool holder 2b of the writing tool support arm 2 can be controlled to move in the XY and Z axis directions. I have.

[Problems to be solved by the invention]

In the above configuration, when the writing instrument support arm 2 has to be replaced, the writing instrument support arm 2 is moved to Y.
In this case, it is necessary to remove the writing tool support arm from the cursor 6, and when the new writing tool support arm is attached to the Y cursor 6, readjustment of the rotating part is troublesome, and there is a defect that the writing tool support arm cannot be easily replaced. did.

The purpose of the present invention is to eliminate the above-mentioned defects.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a casing mounted on a mounting surface and having an X along an opening of the casing.
The Y-cursor is supported so as to be movable in the Y-axis direction in the front-rear direction with respect to the shaft and the opening, and the rear end of the writing instrument support arm is rotatably supported on the Y-cursor about an axis parallel to the X-axis. In an automatic imager having a writing tool holding portion provided at a distal end portion of the writing tool support arm that protrudes from the opening of the writing tool support arm, an attachment body is provided on both sides of the Y cursor around an axis parallel to the X axis direction. The writing instrument support arm is rotatably supported, and the rear end portion of the writing instrument support arm is detachably attached to the attachment. The writing instrument support arm is attached to the Y through the attachment.
It is connected to a cursor so as to be rotatable about an axis parallel to the X axis.

[Action]

The replacement of the writing instrument support arm can be achieved by removing the old writing instrument support arm from the attachment and attaching the new writing instrument support arm to the attachment. This operation can be easily performed without adjusting the rotating section.

〔Example〕

Hereinafter, the configuration of the present invention will be described in detail with reference to embodiments shown in the accompanying drawings.

Reference numeral 12 denotes a casing having a bottom shape suitable for mounting on a mounting surface such as a drawing board. The casing
X-axis guides 14 and 16 are installed in parallel with the X-axis direction of 12, and X cursors 18 and 20 are movably connected thereto. A Y-axis guide 22 is provided between the X cursors 18 and 20. A moving frame 24 is slidably fitted to the Y-axis guide 22 via a linear stroke bearing.
A Y cursor 26 is fixed to 24. The Y cursor 26
A pivot bearing hole 28 is formed on both sides of the shaft. 30
Is a U-shaped mounting body, and the rising protruding pieces 30a, 30b thereof
Threaded holes 32 and 34 are formed in the mounting body 30, and arm mounting tongues 30c and 30d are formed on one side of the mounting body 30. Screw holes 36, 38 are formed through the arm mounting tongues 30c, 30d. The mounting body 30 has projecting pieces 30a, 30b loosely disposed opposite to both side surfaces of the Y cursor 26, and the ends of pivot shafts 40, 42 which are screwed into screw holes 32, 34 have the pivot bearing holes. Press into 28,
Thereby, the mounting body 30 is rotatable within a predetermined range around the axis parallel to the X-axis guides 14 and 16 within the predetermined range.
It is connected to the cursor 26. 44 is a writing instrument support arm, screw insertion holes 46 and 48 are provided near the rear end of this,
The mounting screws 50 and 52 inserted into the holes 46 and 48 are
6,38, which allows the writing instrument support arm 44
Is detachably fixed to the mounting body 30. A holding portion for holding a writing implement 54 is provided at the tip of the writing implement support arm 44.
A holder member 56 having 56a is fixed, and the holder member 56
Protrudes forward from the casing 12 by a predetermined distance from an opening 58 in the front wall of the casing 12. Reference numeral 58 is associated with the lifting (Z) drive system. A lifting bar, and the writing instrument support arm 44
It is arranged below.

 Next, the operation of the present embodiment will be described.

By operating the keyboard provided on the casing 12 and inputting the drawing information to a controller composed of a microcomputer built in the casing 12, the controller
Control the drive system. The X drive system moves the X cursors 18 and 20 in the X direction along the X axis guides 14 and 16, the Y drive system moves the Y cursor 26 in the Y direction along the Y axis guide 22, and the Z drive system. The lifting bar 58 moves up and down. X above
By the drive of the Y, Z drive system, the writing instrument support arm 44 moves the X, Y, Z
In the direction, the movement is controlled on the paper on the mounting surface, and the drawing information input to the keyboard is drawn on the paper. The writing instrument support arm 44 is removed from the mounting body 30 by removing the screws 50 and 52 from the screw holes 36 and 38 of the mounting body 30 or by screwing the screws 50 and 52, that is, Y
It can be removed from or attached to the cursor 26.

In the above embodiment, the writing instrument support arm is detachably attached to the attachment body by a screw. As shown in FIG. 5, the projection 62b of the attachment body 60 and the guide 62, 64, 66, and the guides 62, 64, 66 and the protruding piece 60b constitute a slide insertion frame. When the rear end of the writing instrument support arm 68 is slid and inserted into the slide insertion frame, the mounting body 60 Bush and other fixing projections 70, 7
2 may be fitted into the fixing projections 74, 76 of the writing instrument support arm 68, whereby the writing instrument support arm 68 may be detachably fixed to the attachment body 60.

〔effect〕

In the present invention, as described above, since the Y cursor, the mounting body, and the writing instrument support arm are independently assembled, when it is desired to replace only the writing instrument support arm, without removing the rotating portion between the Y cursor and the mounting body. In addition, the writing instrument support arm can be easily replaced, and there is an effect that this replacement does not require adjustment of the rotating portion.
