Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an XY plotter that draws by relatively moving a pen and recording paper.

Conventional configurations and their problems In general, there are two types of XY plotters: flat vest type and drum type.The former is large in size, and the latter cannot handle thick paper such as postcards, and it is difficult to see the state during drawing. As a countermeasure to these drawbacks, the XY Pro is small and does not depend on the type of paper, and draws by sliding the paper across the table.

was proposed.

A conventional XY plotter will be explained below.

FIG. 1 shows a plan view of a conventional XY prosthesis. Here, a carriage 4 supported by a carriage guide 3 and having a pen 11 is moved in the direction of arrow X by an X-axis drive motor 1 via a wire 6. or,
Recording paper 10 held between drive roller 6 and pinch roller 8
slides on the table 9 in the direction of arrow Y by rotating the drive roller 6 forward and backward by the Y-axis drive motor 2.

As described above, drawing is performed on the recording paper 10 by the pen 11 on the platen 7 by relative movement of the pen 11 in the X direction and the recording paper 10 in the Y direction.

However, in the conventional XY plotter as mentioned above, the first
As shown in FIG. 2, which is a cross-sectional view of the figure, Y
When the drive roller 6 rotates in the direction of the arrow a due to the rotation of the shaft drive motor 2 and the recording paper 1Q is moved in the direction of the arrow, the recording paper 10 is moved between the drive roller 6 and the pinch roller 8.
and the point Q where the pen 11 clamps the cut paper 1o and presses it against the platen 7 with a specified pressure is Y.
Due to the distance in the direction, if the rotation of the platen 7 is not smooth, the recording paper 10 will not rotate as shown by the broken line.
A jamming state occurs with oa and 1ob.

Furthermore, even if the recording paper 10 is thin and weak, the jamming phenomenon described above is likely to occur.

That is, when the recording paper 10 is sent in direction b by the rotation of the drive roller 6, the platen 7 needs to rotate before the recording paper 10 becomes jammed between 10a and 10b, but the action of rotating the platen 7 is Since it depends only on the feeding action of the recording paper 10, jamming phenomenon is very likely to occur. When this jamming phenomenon occurs, the relative movement state between the pen 11 and the recording paper 10 is disrupted, resulting in a major drawback in terms of drawing quality, in that regular drawing cannot be performed.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and the recording paper does not cause jamming phenomenon, and the relative movement between the pen and the recording paper can be performed smoothly, and good drawing quality can be obtained. The purpose of the present invention is to provide an XY plotter that can perform

Structure of the Invention The present invention provides a table for supporting recording paper, a carriage guide provided parallel to the table and extending in the X direction, and a printing means supported by the carriage guide and slidable in the X direction. and an X
a shaft drive motor, a platen disposed parallel to the carriage guide, a drive roller that drives the recording paper on the table in the Y direction perpendicular to the X direction, and a forward moving recording paper along with the drive roller. , a Y-axis drive motor for driving the drive roller, and a second transmission means connected to transmit rotation of the drive roller to tilt the platen;
By providing the transmission means, it is possible to smoothly move the pen and the recording paper relative to each other, thereby eliminating the jamming phenomenon of the recording paper and achieving good drawing quality.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 6. FIG. 3 is a side view of the drive roller and platen portion of the XY plotter in the first embodiment of the present invention. Here, 9 is a table, 12 is a belt, and a drive pulley part 13 rotates synchronously on the same axis as the drive row 26.
A belt 12 is interposed between a passive pulley section 14 that rotates synchronously on the same axis as the platen 7. The reduction ratio of the drive pulley section 13 and the passive pulley section 14 is determined so that the circumferential speeds of the drive roller 6 and the platen 7 are the same, and the rotation of the drive roller 6 is forcibly controlled via the transmission means of the belt 12. The platen 7 is rotated.

Further, FIG. 4 shows a side view of the drive roller and platen portion of the XY plotter in the second embodiment of the present invention. Here, reference numeral 15 denotes an idler roller, which forcibly rotates the platen 7 by transmitting the rotation of the drive roller 6 through a transmission means called the idler roller 15. FIG. 6 is a side view of the drive roller and platen portion of the XY plotter according to the third embodiment of the present invention. Here, 16 is a gear that is coaxial with the drive roller 6 and rotates synchronously, 17 is an idler gear, and 18 is a gear that is coaxial with the platen 7 and rotates synchronously.
The rotation of the drive roller 6 is forcibly transmitted to the platen 7 using gears 17 and 18 as transmission means. Note that the reduction ratios of the gear 16, idler gear 17, and gear 18 are such that the peripheral speeds of the drive roller 6 and the platen 7 are the same. FIG. 6 is a side view of the drive roller and platen portion of the XY block according to the fourth embodiment of the present invention. here,
19 is a magnetic roller that rotates coaxially and synchronously with the drive roller 6;
20 is a magnetic idler roller, 21 is platen 7! ! : A magnetic roller that rotates coaxially and synchronously, and forcibly transmits the rotation of the drive roller 6 to the platen 7 via a transmission means called magnetic force.

As described above, according to the first to fourth embodiments, by forcibly transmitting the rotation of the drive roller 6 to the platen γ via various transmission means, the relative relationship between the ben 11 and the recording paper 1o can be adjusted. Since the movement is smooth, jamming of the recording paper 1o does not occur, and good drawing quality can be obtained. Furthermore, it is possible to handle even thinner recording paper than the conventional method.

DETAILED DESCRIPTION OF THE INVENTION As described above, the XY plotter of the present invention includes a table for supporting recording paper, and an XY plotter provided in parallel with the table.
a carriage guide extending in the X direction, a carriage supported by the carriage guide, slidable in the X direction and equipped with a printing means, and an X axis for driving the carriage in the X direction via a first transmission means. A drive motor, a platen disposed parallel to the carriage guide, a drive roller that drives the recording paper on the table in the Y direction perpendicular to the X direction, and a drive roller that drives the recording paper together with the drive roller 2. The device includes a pinch roller for pinching, a Y-axis drive motor for driving the drive roller, and a second transmission means connected to make the circumferential speed of the drive roller and the platen the same. By providing the second transmission means, the platen is forcibly rotated when the drive roller rotates, that is, when the recording paper is conveyed, so that the relative movement between the pen and the recording paper becomes very smooth.

The jamming phenomenon of the recording paper is eliminated, and good drawing quality can be obtained. Moreover, it is possible to realize an excellent XY plotter that can handle even thinner recording paper than conventional systems.
