Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper and lower device of a cutter for a recording apparatus that cuts a recording sheet recorded in a recording apparatus.

[Prior Art] As the prior art of the present invention, the applicant of the present application
There is an invention relating to a “recording device” filed on November 17 (hereinafter referred to as a prior invention).

FIG. 3 is a sectional view showing an embodiment of the invention of the prior application, in which (1) is a recording pen, (2) is a pen block,
(4) is a recording paper, (6) is a round blade of a cutter unit,
(7) is a platen, (8) is a paper pressing roller, (41)
Denotes a drive roller, (42) denotes a pinch roller, (43) denotes a platen roller, and (71) denotes a cutter groove provided in the platen (7).

The following description is based on the assumption that XYZ orthogonal coordinates are used, where the paper feeding direction of the printing apparatus is the X-axis direction and the direction perpendicular to the surface of the printing paper (4) at the printing point is the Z-axis direction.

The pen block (2) is mounted on a Y-axis slider (not shown) so as to slide on the Y-axis, and the paper holding roller (8) has a fixed position relative to the round blade (6). The round blade (6) and the paper pressing roller (8) are held by the pen block (2) so as to be able to move up and down in the Z-axis direction with respect to the pen block (2).

FIG. 3 shows a so-called pen-down state, in which a recording pen (1) is used.
Indicates a state in which recording is being performed. Accordingly, the cutter unit is raised in the Z-axis direction, and even if paper feeding is performed in this state, the cutter unit does not become an obstacle.

Then, when cutting the recording paper (4), first raise the recording pen (1), separate the tip of the recording pen (1) from the surface of the recording paper (4), and feed the recording paper (4). Then, the position of the recording paper (4) to be cut is brought directly below the round blade (6), the cutter unit is lowered, and the pen block (2) is driven in the Y-axis direction.

FIG. 4 is a cross-sectional view showing an example of a cutter unit up-down control device, showing projection on the YZ plane. FIG. 4 (a) shows the cutter unit down, and FIG. 4 (b) shows the cutter unit up. Are respectively shown.

4, the same reference numerals as those in FIG. 3 denote the same or corresponding parts, (3) is a pen holder, (5) is a Y-axis slider, (12) is a rotating shaft of a round blade (6), and (13) is a bearing. , (14) is a spring, (15) is a cam lever, (16)
Indicates a cam lever shaft, and (17) indicates a shaft of a cutter unit.

The bearing (13) and the cam lever shaft (16) are fixed to the pen block (2), 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. (A), the spring (14) is compressed by the cam, and the round blade (6) keeps its lowered state. When the cam lever (15) is rotated in the direction of the arrow in the drawing, the contact surface of the cam is retracted, the spring (14) is extended, and the cutter unit is raised. Becomes

The shaft of the paper pressing roller (8) is attached to an extension of the shaft (17) of the cutter unit, and when the cutter unit is in a cutter down state, it is pressed against the surface of the recording paper (4), and the pinch roller shown in FIG. It operates so that the recording paper (4) is slackened together with (42).

[Problems to be Solved by the Invention] Since the above-mentioned conventional vertical device of the cutter for a recording apparatus is configured as described above, the rotation of the cam lever is performed directly or manually by inputting a control signal manually. Therefore, there is a problem that it is an obstacle in achieving automation.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to obtain a cutter vertical device for a recording apparatus that can automatically move up and down a cutter unit in conjunction with an overall operation for drawing. It is an object.

[Means for Solving the Problems] A vertical device for a cutter for a recording apparatus according to the present invention includes:
A cam lever push rod that pushes a cam lever close to one end of the Y-axis slider to rotate this cam lever in one direction, and a cam lever that pushes a cam lever near the other end of the Y-axis slider to rotate this cam lever in the opposite direction. A cam lever push rod is provided.

[Operation] In the present invention, by providing the cam lever push rods as described above at both ends of the Y-axis slider, it is possible to perform the up / down control of the cutter unit only by moving the pen block.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a partial cross-sectional view showing one embodiment of the present invention, and shows a projection onto a YZ plane. In FIG. 1, the same reference numerals as those in FIGS. 3 and 4 denote the same or corresponding parts, (18) a turret (19) for holding a replacement pen, a turret motor for driving the turret (18), (21) , (22) indicate cam lever push rods, and (23), (24) indicate covers.

FIG. 2 is a perspective view showing an example of the positional relationship between the cam lever push rod (22) and the cam lever (24).

When the right direction of the Y-axis slider (5) shown in FIG. 1 is assumed to be a positive direction and the left direction is assumed to be a negative direction, when the pen block (2) is near the end in the negative direction, the cam lever (15) pushes the cam lever. When the pen block (2) abuts on the rod (21) and further moves in the negative direction, the cam lever (15) is pushed by the cam lever push rod (21), and the cam lever (15) rotates clockwise. Then, when it reaches the transfer point, it automatically shifts from the first cam position to the second cam position, lowers the round blade (6) and the paper pressing roller (8), and maintains this second cam position. .

In this state, the pen block (2) is moved in the forward direction on the Y-axis slider (5) to cut the recording paper (4).

When the cutting of the recording paper (4) is completed, the pen block (2)
Is reversed and moves in the forward direction. This movement in the forward direction causes the cam lever (15) to move in the direction of the cam lever push rod (22).
Abut. When the forward movement of the pen block (2) further proceeds, the cam lever (15) is pushed by the cam lever push rod (22), and the cam lever (15) rotates clockwise. Then, when it reaches the transition point, it automatically returns from the second cam position to the first cam position, and returns to the cutter-up state.

Therefore, if the platen width is P1-P2 and the paper width is A1-B, the recording range is A2-B.

In order to prevent the cutter down control from being performed when the cutting command is not issued, for example, a magnetic plunger (not shown) may be used to move the cam lever push rod (22) in and out in the Y-axis direction. The cam lever push rod (22) may be made to protrude in the Y-axis direction and come into contact with the cam lever (15) only when a cutting command is issued.

In addition, the patent invention (Japanese Patent Publication No. 1-2144)
No. 5) As disclosed in "Pen Replacement Device for Recorder", a turret (18) for holding a replacement pen is provided at the forward end of the Y-axis slider (5). Therefore, when the pen block (2) approaches the positive end of the Y-axis slider (5), the turret is rotated at an angle such that the turret (18) does not hinder the movement of the pen block (2). Although it is necessary, this control may be performed by a cutting command.

According to the present invention, the cutter up / down operation can be automatically executed by a cutting command.

In the above embodiment, the push rods (21) and (22) are provided on the covers (23) and (24). However, the present invention is not limited to this, and the push rods (21) and (22) are provided at positions fixed to the platen (7) and the cam lever ( 1
5) may be provided at any position as long as it comes into contact as described above.

[Effects of the Invention] As described above, the present invention has an effect that the cutter up / down control of the cutter unit mounted on the recording apparatus using the roll recording paper or the like can be automatically executed.
