2. Description of the Related Art Conventionally, a member to be cut such as a cloth is spread on a cutting table, and a cutting head equipped with cutting means moves on the cutting table according to the cutting data and automatically cuts a part having a desired shape. The cutting machine is designed to give marks to the cut parts as markings at the positions (marking points) where joints with other parts, pocket positions, button holes, sewing stop marks, etc., that are necessary for later sewing work are provided. A marking device is provided. As a method of giving a mark, generally using a drilling means such as a drill,
A method using a marking pen using a consumable marking rod or a coating means such as marking paint is generally used.

Cutting is roughly classified into multi-layer cutting in which a plurality of cloths are spread on a cutting table at a time for cutting, and single cutting in which one cloth is spread and cut on a cutting table. . In the multi-layer cutting, a mark is applied to a plurality of cloths at a time by piercing the cloth with a piercing means such as a drill that is vertically movable with respect to the cloth. In the method of marking with a perforating means such as a drill, damage to the fabric occurs, but it is possible to apply the mark to multiple fabrics at once,
In an automatic cutting machine that prioritizes efficiency and performs multi-layer cutting, a marking device using a perforating means such as a drill is generally provided.

In the one-sheet cutting, as the name implies, only one sheet of cloth is spread on the cutting table to perform cutting, or wasa cutting is performed in the state where one sheet of cloth is folded in two. Then, the cutting is performed by a cutting method in which symmetrical parts such as the left and right front body parts are cut at once. The single sheet cutting is often performed at the time of cutting a high-grade cloth or a custom-made cloth, and in that case, marking by a perforation means such as a drill that damages the cloth is not suitable.
In addition, in the case of cutting with washer, for example, in the case where a pocket is provided only on one side of the body part, when a mark is given only to the dough located on the surface side of the doubly overlapped dough, Since it is not possible to perform marking by such a punching means, generally marking is performed by a marking means that does not damage the cloth such as a marking pen.

The descent of the marking head 7 is stopped when the lower surface of the base portion 13 contacts the vinyl sheet 6. After the formation of the cutout portion 73 is completed, the eccentric cam 38 is rotated again in the counterclockwise direction to return the elevating member 35 to the raised position and set in the standby state, whereby the formation of the cutout portion on the vinyl sheet 6 is completed. To do. At this time, as shown in FIG. 9, the horizontal portion 25 of the L-shaped lever 26, which is in contact with the cutter blade 19, swings in the away direction to form the incision portion 73, so that the marking point M can be reliably formed. In order to form the cutout portion 73, when the cutting head 5 is moved onto the marking point M, the center O of the cutter blade 19 in the blade width direction is located at a position offset from the marking point M by a predetermined amount (P). Further, it is preferable that the cutting head is moved by the control device to form the incision 73. By doing so, the marking point M is located at the central portion of the incision portion 73, and it is possible to reliably apply the mark later.

Next, a mark is given to the cloth 3 from the cutout 73 formed. A control device for moving the cutting head 5 so that the tip of the marking pen 10 of the marking head 7 is located on the marking point M in the incision 73 formed in the vinyl sheet 6 with the elevating member 35 in the standby state.
