In order to achieve the above object, the present invention provides an arm (10) capable of moving up and down an object head (2).
The cutter pen (16) is held at (12), and the object head (2) is moved in the direction crossing the vertically long sheet (6) on the drawing (4a). In a sheet cutting device of a plotter adapted to cut a sheet (6) in a transverse direction, the cutter pen (16) extends in a direction perpendicular to an axial direction of the cutter pen (16), and a tip end thereof is formed in the drawing. (4a) and paper (6) on it
A cutter guide (22) having an elongated underlay (22b) formed in a shape easily inserted between the cutter pen (16) is attached to the underlay (22b) of the cutter guide (22). The blade (16a) is abutted to cut the paper (6) on the drawing (4a) between the cutter blade (16a) and the underlay (22b).

[0005]

The paper (6) such as a roll paper which is long in the vertical direction on the drawing (4a) is provided with the cutter pen (16) and the underlay (22).
b), the cutter pen (1) is cut transversely.
6) does not touch the drawing (4a) and therefore the drawing (4a)
a) is not damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. (2) is an image head of a paper drive type (paper moving type) plotter, and its casing (2a) is arranged above a drawing roller (4) at a right angle to the drawing rail (4). (Not shown). The surface of the drawing roller (4) constitutes a drawing (4a).

The drawing roller (4) has its surface, that is, a drawing (4a), positioned in a slit formed in a Y-axis direction on a platen (sheet mounting plate), and is rotatably disposed. The surface of the drawing roller (4) in the slit and the surface of the platen are set substantially on the same plane. A paper (6) such as a roll paper that is long in the longitudinal direction on the platen includes a driving roller (not shown) arranged in parallel with the drawing roller (4) and a pressure roller arranged to be movable up and down with respect to the driving roller (Not shown), and is configured to be reciprocated on the platen in the direction perpendicular to the sheet of FIG. 1A, that is, in the X-axis direction by forward and reverse rotation of the drive roller.

The object head (2) includes an elevating body (8). The elevating body (8) is connected to an elevating drive device including a moving coil incorporated in a casing (2a) of the head (2). Connected. The lifting body (8) includes a fixed arm (10) for holding a pen, and a movable arm (12).
The pen holding center axis of the arm (10) (12) to which is attached is set above the drawing (4a), and the drawing pen (14) held by the arm (10) (12). Or the tip of the cutter pen (16) is just
It is configured to be located immediately above the drawing (4a).

A rotary pen stocker (18) (commonly called a carousel) is rotatably disposed on the body of the plotter near the end of the Y-rail, and is provided around the circumference of the pen stocker (18). Is provided with a plurality of pen holding mechanisms (20) at the intervals. The pen holding mechanism (20)
Each of them holds a drawing pen (14) and a paper cutting cutter pen (16) having the same type of holder as the drawing pen (14). The plotter is configured such that pens can be automatically exchanged between the object head (2) and the pen stocker (18). When drawing, the plotter is connected to a fixed arm (10) of the object head (2). The movable arm (12) holds a drawing pen (14) as shown in FIG.

At the time of drawing, the controller of the plotter rotates the drive roller forward and reverse based on the drawing data transferred from the host computer to feed the sheet (6) on the platen in the X-axis direction, The pen (14) is sent to the fixed arm (10) and the movable arm (12) so as not to be displaced in the axial direction while driving (2) in the reciprocating direction along the Y rail and driving the lifting / lowering drive device. Is brought into contact with or separated from the sheet (6) on the drawing (4a).

By the above-mentioned operation, drawing for a predetermined frame is performed on the sheet (6) on the platen. During the drawing operation, the drawing roller (4) rotates synchronously at substantially the same peripheral speed as the drive roller, so that a large frictional force does not occur between the sheet (6) and the surface of the drawing roller (4). In FIG. 3 (3), (22) is a cutter guide made of plastic or the like, and a ring-shaped mounting portion (22a).
An elongated plate-shaped underlay (22b) disposed horizontally below the mounting portion (22a) in the diametric direction thereof; and an elongated connecting the underlay (22b) and the mounting portion (22a). And a plate-shaped connecting portion (22c).

At the inner diameter of the mounting portion (22a), a cutter guide (2) is attached to a holder of the cutter pen (16).
2) Rubber ring (24) for firmly fitting
Are arranged. The mounting part (22a) is detachably fitted to the holder part of the cutter pen (16), and in this mounted state, the cutter blade (1) of the cutter pen (16) is attached.
The tip of 6a) is in contact with the upper surface of the underlay (22b). At the tip of the underlay (22b), the underlay (22b)
An inclined surface (26) is formed so that b) can easily pass under the sheet (6) on the drawing (4a).

When an eccentric cutter pen having directionality is used as the cutter pen (16), the underlay portion (22b)
The cutter guide (22) is mounted on the cutter pen (16) such that the direction of the blade of the cutter blade (16a) that abuts on the cutter pen (16) is directed to the tip of the underlay portion (22b). Next, the sheet cutting operation of the image head (2) will be described.

In the case of printing using continuous paper that is long in the vertical direction such as roll paper, when printing for one frame is completed on the paper (6), the position where the paper (6) should be cut is set on the drawing roller (4). To the position of the cutter pen movement locus. Next, the controller places the drawing pen (14) held by the object head (2) on the empty pen holding mechanism (20) of the pen stocker (18) as shown in FIG. Thereafter, the pen stocker (18) is rotated, and the pen holding mechanism (20) for holding the cutter pen (16) of the pen stocker (18) is moved to the image head (2) as shown in FIGS. ). At this time, the cutter guide (2) attached to the cutter pen (16)
2) The underlay (22b) is oriented parallel to the Y-rail or drawing roller (4). Next, as shown in FIG. 5 (5), the image head (2) controls the cutter pen (1) of the pen stocker (18) under the control of the controller.
Go to 6) and hold the cutter pen (16) between the fixed arm (10) and the movable arm (12).

Next, on the end of the drawing roller (4) on the pen stocker (18) side, the lifting / lowering body (8) is lowered, and the cutter guide (22) is moved outside the paper support area to the drawing roller (4).
Contact. Next, the controller moves the object head (2) rightward in FIG. 1A along the Y rail. When the cutter guide (22) reaches the left end of the paper (6), the underlay (22b) enters between the lower surface of the paper (6) and the surface of the drawing roller (4). When the image head moves rightward, the paper (6) is cut linearly along the Y axis by the cutter blade (16a) on the underlay (22b) of the cutter guide (22).

When the cutting operation is completed, the object head (2)
Returns the cutter pen (16) to the empty pen holding mechanism (20) of the pen stocker (18) and goes to the pen stocker (18) to pick up the drawing pen (14) in preparation for the next drawing. . In this embodiment, the cutter guide (2
Although 2) is configured to be detachable from the cutter pen (16), it may be configured to be fixed to the cutter pen in advance. In addition, the cutter pen is not particularly limited to an eccentric cutter pen having directivity.

According to the present invention, as described above, since the paper cutting operation is performed on the underlay of the cutter guide, there is no possibility that the screen is damaged by the cutter blade.
