The needle 34 is fixed to the output portion of the lifting drive device such as the solenoid.

On a roll support 36 (see FIG. 3) supported by the machine body, a shaft member for supporting a roll portion 38a of a copy paper 38 made of strip-shaped carbon paper is rotatably supported. Reference numeral 42a is a roll portion of the belt-shaped cover / pattern paper 42 which is rotatably supported so as to be able to move up and down in a U groove formed in the roll support 36 and to rotate around the roll portion 38a.

Reference numeral 44a denotes a roll portion of a long belt-shaped cloth 44, and its support shaft is rotatably supported by the machine body. The support shaft of the roll 44a and the support shaft of the roll portion 38a are connected to the output shafts of the motors 46 and 40, respectively.
a, 38a are driven by these motors 46, 40 to
4, the copying paper 38 and the pattern paper 42 are rotationally driven in a feeding direction.

In the figure, reference numeral 48 is a pressing roller 50, 52 is a sensor. The XY motor, the motors 28, 46, 40,
The solenoid built in the head 14 and the solenoid built in the carrier 30 are configured to be controlled by the controller.

Next, the operation of this embodiment will be described. First, the preparation work will be described. The power switch is turned on and the solenoid of the carrier 30 is driven to raise the needle 34.

Next, the Y rail 14 is moved in the right direction in FIG. 2, that is, the plus X direction, and the Y rail 14 is slowly moved to the origin position at the right end in the figure on the vacuum table 12.

Next, on the conveyor belt 26, the sheet material 54 in which the cloth 44, the copy paper 38, and the cover / template 40 are stacked in this order from the bottom is set on the upper horizontal portion of the conveyor belt 26.

Next, the carrier 30 is manually adjusted in position and the needle 3
Align 4 with the shortest sheet. Next, the vacuum table 12 is turned on, and the sheet material 54 is fixed on the vacuum table 42 by suction.

The preparatory work is completed by the above operations. In the preparatory work, the vacuum table 12 may be turned on at the same time when the power switch is turned on. Next, the drawing and cutting work will be described.

The drawing switch is turned on, the cutter 20 or the pen 21 is selected, the head 18 is moved in the XY directions on the table 12, and the cutter 20 or the pen is displayed on the sheet material 54 in the Z-axis direction as the drawing information. Draw and cut one frame.

After drawing and cutting, as shown in FIG. 4, the solenoid of the carrier 30 is turned off, the needle 34 is lowered by the spring force, and the sheet material 54 and the conveyor belt 26 are pierced by the needle 34. The tip of the needle 34 is shown in FIG.
As shown in FIG. 5, the elastic force of the spring for urging the output shaft of the solenoid is set so as to stop immediately in front of the vacuum table 12.

Next, the Y-rail 14 and the output side of the motor are cut off by the clutch-off to bring the Y-rail 14 into a free movement state. Next, the vacuum table 12 is turned off or the wind is blown up to release the fixing of the sheet material 54 to the vacuum table 12. Next, the motor 28 is driven to drive the conveyor belt 26 in the counterclockwise direction, and the needle 34
The sheet material 54 and the Y rail body 14 are conveyed in the minus X direction while the sheet material 54 and the conveyor belt 26 are pierced.

When the sheet body 54 is fed out, the roll portions 44a and 38a are rotationally driven in the feeding direction by the motors 46 and 40.

By moving the conveyor belt 26 in the negative direction, the sheet material 5 for the next drawing and cutting is formed.
4 is transported to the vacuum table 12, that is, to the work area.

After the sheet material 54 is conveyed onto the vacuum table 12, the solenoid is turned on and the needle 34 is driven in the ascending direction, so that the needle 34 is pulled out from the sheet material 54. Next, the Y rail 14 is driven in the plus X direction and slowly moves to the origin position.

If drawing and cutting are to be continued on this sheet material without replacing it with another sheet material, the above-mentioned drawing and cutting operations are performed. If another sheet material is used, the sheet material is replaced with a desired sheet material, and the above-mentioned preparation work is performed.

Even if the feeding motors 46 and 40 are driven, if the sensors 50 and 52 do not operate at a predetermined timing, the controller determines that there is no paper / material, and the apparatus stops.

The cover / pattern paper 42 is used for enhancing the suction force of the cloth 44, strengthening the cloth 44 when it is not stiff, or when it is necessary to copy the paper pattern.

In the above embodiment, the conveyor belt 26 is used, but as shown in FIG.
The Y-rail 14 may be driven by a motor along the X-axis guide to convey the sheet material.

In FIG. 6, a roll portion 58a of the cloth 48 is a roll portion of the breathable underlay sheet 58, and the roll portion 58a is rotationally driven by the motor 46 in the feeding direction. At this time, the roll portion 44a is the roll portion 5
8a. Sheet material 6
As shown in FIG. 6, 0 is formed by stacking a cloth 48, a copy paper 38 such as carbon paper, and a cover / pattern paper 42 from the bottom. These sheet materials 60 are the vacuum table 1
It is placed on the underlay sheet 58 above 2. The other structures are the same as those of the first embodiment, and the corresponding structures are designated by the same reference numerals.

The preparatory work in the second embodiment shown in FIG. 5 is the same as that in the first embodiment except that the descending position of the needle 34 with respect to the sheet material 60 is different as shown in FIG. In the second embodiment, the needle 34 pierces the underlay sheet 58.

In the drawing and cutting work,
In the first embodiment, by driving the conveyor belt 26, Y
Although the rail 14 and the sheet material 54 were transported, in the second embodiment, the sheet material 60 is transported together with the underlay sheet 58 by the movement of the Y rail 14.
