[Problems to be solved by the device]

 In the above plotter, the two fixed rails have to be long, which makes it difficult to accurately attach the two rails to the machine body. In addition, improving the accuracy of the straightness of the rail itself has a problem that the longer the rail, the more costly it is. The present invention is intended to solve the above problems.

[0006]

Means for Solving the Problems In order to achieve the above object, the present invention provides a plotter machine, a paper support surface supported by the machine, and a longitudinal direction that is located above the center of the paper support surface. Extends in the first coordinate axis direction over the entire area of the sheet support surface, and one fixed rail whose both ends are supported by the machine body, and the entire length in the longitudinal direction substantially equal to the width of the sheet support surface in the second coordinate axis direction. A movable rail having a longitudinal direction facing the second coordinate axis direction, and a substantially central portion in the longitudinal direction movably supported by the fixed rail; and a pen attached to the movable rail so as to be movable. Alternatively, it is provided with a head for drawing or cutting the paper on the paper supporting surface by a cutter.

[0007]

[Action]

 When the plotting or cutting operation of the plotter is started, the moving rail is controlled to move along the fixed rail in the first coordinate axis direction, and the head is controlled to move along the moving rail in the second coordinate axis direction. On the other hand, the pen or cutter supported by the head is controlled to move up and down, and drawing or cutting is performed on the paper on the paper support surface.

【Example】

 Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. In FIG. 1, reference numeral 20 is a machine body of a plotter, on which a drawing board 22 is supported. As the drawing board 22, a known vacuum table can be used. The sheet support surface 22a of the drawing board 22 is rectangular as shown in FIG.

A fixed rail 24 is installed on the machine body 20 above the drawing board 22. The fixed rail 24 is set such that its longitudinal direction is parallel to both edges 22b, 22c of the paper supporting surface 22a which are parallel to each other in the longitudinal direction, and is positioned at the center of the paper supporting surface 22a. On the other hand, it is set horizontally.

Reference numeral 26 denotes a moving rail, the central portion of which is connected to the fixed rail 24 via a cursor 28 so as to be movable in translation. The movable rail 26 is set horizontally with respect to the support surface 22a and vertically with respect to the fixed rail 24. The movable rail 26 has a sufficient length to cover the entire width of the support surface 22a in the lateral direction.

A known head 30 is movably connected to the moving rail 26 via a cursor (not shown), and a pen 32 or a cutter (not shown) is supported on the head 30. In front of the machine body 20, a roll paper support means 34 is disposed so as to face one edge portion 22c in the longitudinal direction of the drawing board 22. A roll portion 36a of the roll paper 36 is rotatably and detachably supported by the support means 34 in parallel with the edge portion 22c and below the paper support surface 22a.

Behind the machine body 20, parallel to the other edge 22b in the longitudinal direction of the drawing board 22 and positioned below the sheet supporting surface 22a of the drawing board 22, A sheet winding device 38 is rotatably arranged.

As shown in FIG. 4, belt pulleys 40 and 42 are rotatably supported at both ends of the fixed rail 24, and an endless timing belt 44 is stretched between the pulleys 40 and 42. . A cursor 28 integral with the moving rail 26 is connected to one of the parallel portions of the timing belt 44. The pulley 40 is connected to an output shaft of a motor 46 arranged in the machine body 20 via a power transmission mechanism.

By driving the motor 46, the belt 44 moves along the fixed rail 24 and is coupled with the movement of the belt 44 so that the moving rail 26 moves along the fixed rail 24 in the first coordinate axis direction. It is configured to translate.

The motor 46 and the belt 44 form a moving rail drive mechanism. Wire pulleys 48 and 50 are rotatably supported at both ends of the moving rail 26, and endless wires 52 are wound around the pulleys 48 and 50 with appropriate tension. The head 30 is connected to one of parallel portions of the wire 52.

The pulley 50 is linked to an output shaft of a motor 54 that is fixed to the end of the moving rail 26. By driving the motor 54, the wire 52 moves along the moving rail 26, and in conjunction with the movement of the wire 52, the head 30 moves along the moving rail 26 in the second coordinate axis direction. Has been done. The motor 54 and the wire 52 form a head drive mechanism.

The head 30 has a pen or cutter up-and-down drive mechanism and a cutter rotation direction control mechanism built-in. The roll paper winding means 38 is linked to a motor (not shown).

In the above-described configuration, the controller rotates and drives the roll paper take-up unit 38 to take up a predetermined amount of the roll paper 36 that has been drawn, and the predetermined amount of the roll paper 36 is taken up on the roll paper 36. 22a is developed and arranged.

When drawing or cutting is started, the controller drives and controls the motors 46 and 54, the moving rail 26 is controlled to move along the fixed rail 24 in the first coordinate axis direction, and the head 30 moves to the moving rail. Along the line 26, movement control is performed in the second coordinate axis direction.

On the other hand, the pen 32 or the cutter is controlled to be moved up and down in the third coordinate axis direction by the controller, and drawing or cutting is performed on the roll paper 36 on the support surface 22a. In implementing the present invention, in order to stably move the moving rail 26, brackets 56 and 58 are vertically fixed to both ends of the moving rail 26 as shown in FIG. The rollers 60 and 62 may be rotatably supported by the rollers 56 and 58, and the rollers 60 and 62 may be movably mounted on the drawing board 22.
