Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a pen-type recording device used in X-Y plotters, drafting machines, graphic writers, and the like.

Structure of conventional examples and their problems In recent years, pen-type recording devices have become more popular with the development of computers.
Terminal devices are required to be small, high speed, highly accurate, and compatible with various paper sizes.

A conventional pen-type recording device will be explained below.

FIG. 1 shows a perspective view of a conventional pen-type recording device. In the figure, 1 is a paper drive roller driven by a Y motor 2. A pinch roller 3 is rotatably attached to a pinch roller shaft 4 disposed parallel to the paper drive roller 1, and pinches the recording paper 6 together with the paper drive roller 1. The pinch rollers 3 are located at both ends of the recording paper 6, and both ends of the outer periphery of the paper drive roller 1 (portions in contact with the pinch roller 30) are subjected to surface treatment such as low left to increase total friction. ing. Reference numeral 6 denotes a carriage having a vertically movable pen 7, which slides on an X rail 8 disposed parallel to the paper drive roller 1, and the pen 7 descends onto a smooth portion above the paper drive roller 1.

9 is a transmission member 1o such as a carriage 6-wire, belt, etc.
It is an X-driven mortar driven by . Reference numeral 11 denotes a recording paper base on which the recording paper 6 slides.

The operation of the conventional pen-type recording device configured as described above will be described below.

When the Y motor 2 rotates with the pinch roller 3 and the paper drive roller 1 holding the paper 6 between them, the paper 6 is moved due to high friction parts such as knurling on the outer periphery of the paper drive roller 1. Slide on the recording paper table 11 in the direction of arrow Y. When the rotary X motor 9 rotates, the transmission member 10 causes the carriage 675S to slide on the X rail 8 and move in the direction of the arrow X. Therefore, if the Y motor 2 and the
Adding li control enables flexible recording.

However, the conventional pen-type recording device as described above has a mechanism that moves the pinch roller 3 in the X direction in order to attach the narrow recording paper 6. Even if provided, the surface treatment that increases friction, such as the knurling on the outer periphery of the paper drive roller 1, would have to extend to the moved pinch roller 3, and if a wide recording paper 6 is inserted. , within the effective drawing range, the low reflex of the outer periphery of the paper drive roller 1)
etc., and the drawing quality deteriorates significantly. Therefore, there is a drawback that only a certain width of recording paper 6 can be used.

OBJECTS OF THE INVENTION The present invention is intended to eliminate all of the above-mentioned conventional drawbacks, and it is an object of the present invention to provide a pen-type recording device that has a simple structure and can use recording paper of any width.

Structure of the Invention The present invention provides a drive roller driven by a first motor, a platen that is in a depressed state so that the drive roller and recording paper can engage with each other, and has an axis parallel to the drive roller axis; A fixed carriage guide located on the paper drive roller side and parallel to the axis of the drive port, a carriage having a pen that is slidable on the carriage guide and records on the recording paper on a platen, and means for moving the pen up and down. and a second motor for transporting the paper, the first direction is caused by the movement of the recording paper by a drive roller, and the second direction is caused by the movement of the paper and the paper. Because the recording is performed on a platen, it is possible to increase the recording speed, improve recording accuracy, and make the overall shape more compact.Furthermore, since the drive roller and pinch roller are used to hold the entire paper while feeding the air, it is possible to print with any width. Recording paper can be used.

2 is a perspective view of a pen-type recording device according to an embodiment of the present invention, and FIG. 3 is a side sectional view of the same.

In the figure, 12 is a drive roller whose outer periphery has a surface treatment that increases friction such as knurling, and is connected to the Y motor 14 at 71.
．． It is attached to a shaft 13 such that it is slidable in the axial direction but fixed in rotation.

16 is a platen, which is arranged parallel to the shaft 13. A recording paper 16 is held between the drive roller 12 and the platen 16. Recording paper 16 is presser plate 1
7, the carriage 19 is positioned such that the platen 16 is forced to be in constant contact with the drive roller 12 in a certain section from the outer periphery thereof, and the pen 18 is lowered in that section. The carriage 19 is connected to the drive shaft 13
An X transmission member 2 that is slidable in the direction of the arrow X on an X rail 20 parallel to the
1 is controlled by an X motor 22. Although not shown, there is a means for vertically moving the pen 18 and a platen 16.
There is a way to move the .

23 is a recording paper base.

The operation of the pen-type recording device of this embodiment configured as described above will be explained below.

First, the recording paper 16 is moved to the drive roller 12. Set between the carriage 19, presser plate 17, and recording paper base 23, and then press the platen 15.
When the Y motor 14 rotates by an arbitrary amount, the drive shaft 13
The drive rollers 12, 12' rotate through the drive rollers 12, 12', and the recording paper 16 pressed between the drive rollers 12, 12' and the platen 16 is fed in the Y direction. −? i fc When the X motor 22 rotates by an arbitrary amount, the carriage 19, which can freely slide on the X rail 2Q via the X transmission member 21, moves arbitrarily fi in the X direction L-, thereby causing the Y motor 14. By controlling the X motor 22, the carriage 1 can be moved to any location on the recording paper 16.
9 can be positioned, and the pen 1 has vertical movement means (not shown) held by a carriage 19.
The recording paper 16 is brought into contact with the outer periphery of the platen 16 by the presser plate 17. Therefore, recording with the pen 18 is performed reliably. When using the recording paper 16 having a different width by -1', the drive roller 12 may be moved along the drive shaft to match the width of the recording paper 16.

As described above, according to this embodiment, recording in the Y direction is performed by transporting the recording paper narrowed between the drive roller and the platen in the Y direction by the drive roller, and recording in the X direction is performed by moving the carriage. Since the inertial mass is small, high-speed, high-precision recording is possible, and the shape of the main body in the Y direction does not affect the thickness of the recording paper, making it compact. Because it has a surface treatment that increases friction, it has the added feature of being able to use recording paper of any width.

Effects of the Invention The present invention moves a carriage with a pen in the X direction, moves the recording paper suppressed by a drive roller and a platen in the Y direction, and lowers the pen onto the platen. Since the inertial mass is small, high speed and high accuracy can be achieved, and the main body can be made more compact.In addition, recording paper of any width can be used. This can be realized using a pen-type recording device.
