Description

Description: TECHNICAL FIELD The present invention relates to a recording apparatus that uses roll recording paper or the like, and particularly to cutting of recorded recording paper.

[Prior Art] Srock Roller (stock rolle)
Recording device for roll recording paper that feeds the roll recording paper supplied from r) in the forward or reverse direction on the platen, while recording with the recording pen that moves in the direction perpendicular to the paper feeding direction. Is well known in the art, and a general description thereof will be omitted here. However, in a conventional recording device for roll recording paper, a cutter unit for automatically cutting recorded recording paper is provided. Often not.

The recording device for roll recording paper performs recording on the recording paper while feeding the recording paper in the forward direction or the reverse direction by the grit roller, and if a cutter unit is provided within the range of the paper feeding, This is because the cutter unit becomes an obstacle to paper feeding during recording.

FIG. 3 is a cross-sectional view showing the configuration of a conventional cutter unit used in a recording apparatus using recording paper other than roll recording paper. In the drawing, (1) is a circular blade for a cutter, (2) is a long blade ( Lower blade), (3a), (3b) are recording paper guides,
(4) Recording paper, (11) Round blade mounting base, (12)
Is a rotary blade of a round blade, and (21) is a long blade mounting base.

The paper feed direction of the recording device (not shown) is set to the X-axis direction,
Assuming XYZ rectangular coordinates where the direction perpendicular to the surface of the recording paper (4) at the recording point is the Z-axis direction, the circular blade (1) is centered on the rotation axis (12) and is in the YZ plane. It is attached to the rotary shaft (12) so that it can rotate inside, and the round blade attachment base (11) is attached to the cutter unit so as to be slidable in the Y-axis direction.

Further, the long blade (2) has at least the recording paper (4) in the Y-axis direction.
It has a length equal to the width of, and is called a long blade because of this length.

Then, the recording paper (4) is passed over the long blade (2), and the circular blade mounting base (1) is placed at the position where the recording paper (4) should be cut.
While sliding 1) in the Y-axis direction and rotating the round blade (1), the recording paper (4) is cut between the round blade (1) and the long blade (2).

[Problems to be Solved by the Invention] As described above, the conventional roll recording paper recording apparatus is often not provided with a cutter unit for automatically cutting the recorded recording paper. The problem is that it has to be done manually.

Moreover, in the conventional cutter unit as shown in FIG. 3,
It is dangerous because it is necessary to install the long blade edge on the surface of the writing panel.
Further, there is a risk that the movement of the recording paper may cause the leading edge of the recording paper to hit the blade edge and make an abnormal noise, or the recording paper may be caught. Further, there is a problem that the long blade itself is expensive.

The present invention has been made to solve the above problems, and it is possible to automatically and accurately cut a recording paper sheet that has already been printed without causing an obstacle to paper feeding during recording for printing. It is an object of the present invention to obtain a recording apparatus equipped with an inexpensive and small cutter unit that can be manufactured.

[Means for Solving the Problems] A recording apparatus according to the present invention is provided with a cutter unit integrally with a pen block that slides on a Y-axis slider, and a round blade for a cutter is provided in the Z-axis direction with respect to the cutter unit. It was configured to move up and down, a long blade was omitted, and a cutter groove was provided under the round blade so that the cutter unit would not hinder the movement of the recording paper during recording.

[Operation] In the present invention, the paper holding roller is provided to prevent the recording paper from loosening during cutting, whereby the long blade can be omitted.

Embodiments Embodiments of the present invention will be described below with reference to the drawings. First
The drawing is a cross-sectional view showing an embodiment of the present invention. In the drawing, the same reference numerals as those in FIG. 3 indicate the same or relative portions, (5) is a platen, (7) is a pen block, and (8) is a paper pressing roller. , (51) is a cutter groove provided on the surface of the platen (5), (61) is a drive roller, (62) is a pinch roller,
(63) is a platen roller, (70) is a recording pen, XY
The position in the plane is fixed and is held by the pen block (7) so that it can be moved up and down in the Z-axis direction.

The pen block (7) is mounted on a Y-axis slider (not shown) so as to slide on the Y-axis, and the paper pressing roller (8) is fixed at a position related to the round blade (1). The round blade (1) and the paper pressing roller (8) are held by the pen block (7) so that they can be moved up and down in the Z-axis direction with respect to the pen block (7).

FIG. 1 shows the state in which the recording is performed by the recording pen (70) in the pen-down state. Therefore, the cutter unit is cutter up in the Z-axis direction, and even if the paper is fed in this state, the cutter unit Will not be an obstacle.

When cutting the recording paper (4), first the recording pen (70) is raised, the tip of the recording pen (70) is separated from the surface of the recording paper (4), and the recording paper (4) is fed. Then, the position of the recording paper (4) to be cut may be brought directly below the circular blade (1), and the cutter unit may be cut down to drive the pen block (7) in the Y-axis direction.

Up / down control of the cutter unit is performed by the recording pen (7
A device that performs the same operation as the up / down control of 0) can be used, but other devices such as the second device described later can be used.
You may use the up-down apparatus as shown in the figure.

FIG. 2 is a cross-sectional view showing an example of a cutter unit up / down control device, showing a state in which the cutter unit is being cut down.

In FIG. 2, the same reference numerals as those in FIGS. 1 and 3 indicate the same or corresponding parts. (13) is a bearing, (14) is a spring, (15) is a cam lever, (16) is a cam lever shaft,
(17) shows the axis of the cutter unit.

The bearing (13) and the cam lever shaft (16) are fixed to the pen block (7), and the shaft (17) of the cutter unit moves up and down in the bearing (13). When the cam lever (15) is in the position shown in FIG. 2, the spring (14) is compressed by the cam and the round blade (1) is kept in the lowered state. Then, by rotating the cam lever (15) in the direction of the arrow in the drawing, the contact surface of the cam retracts and the spring (14) extends to raise the cutter unit.

The shaft of the paper pressing roller (8) is attached to the extension part of the shaft (17) of the cutter unit. When the cutter unit is in the cutter down state, it is pressed against the surface of the recording paper (4), and the pinch roller shown in FIG. Together with (62), it operates so as to remove the slack in the recording paper (4). The roller surface of the paper pressing roller (8) may be tapered in the X-axis direction so that the tension in the X-axis direction on the recording paper (4) can be further ensured.

When the cutting of the recording paper (4) is completed, the cam lever (15) is rotated in the direction of the arrow in the drawing to raise the cutter unit.

In the above embodiment, the recording apparatus using roll recording paper has been described, but the present invention can be similarly implemented in a recording apparatus using recording paper other than roll recording paper.

[Effects of the Invention] As described above, the present invention automatically and accurately cuts a recorded recording sheet after plotting, without disturbing the sheet feeding of the recording sheet during recording for plotting. There is an effect that it is possible to obtain a recording apparatus equipped with an inexpensive and small cutter unit that can be used.
