Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an xy plotter for drawing figures on two dimensions.

TECHNICAL BACKGROUND OF THE INVENTION A conventional example will be explained based on FIG. 1. A flat table surface for holding recording paper 2 is formed on the upper surface of the housing 1, and a pen stocker 5 for holding a plurality of pens 4 is fixed to this table surface 3. A pen holder mechanism section 6 is provided on the table surface 3 and extends in the Y direction. This pen holder mechanism part 6 is engaged with a drive source (not shown) provided in the housing l, and
A drive end portion 7 provided to be slidable in the direction is formed at one end, and a slider 8 abutting against the table surface 3 is formed at the other end.
A free end 9 is formed having a diameter. Further, the pen holder mechanism section 6 holds a pen holder 10 that holds one of the pens 4 so as to be movable up and down, and is slidable in the Y direction.

Accordingly, based on command data from a host computer (not shown), the pen holder 1 holding an arbitrary pen 4 is
0 slides in the Y direction, and the pen holder mechanism 6 slides in the X direction while sliding on the slider 8. Therefore, the pen 4 held in the pen holder 10 moves in the X-Y direction, but as the pen 4 selectively moves up and down, the recording paper 2
It plots and draws a figure.

On the other hand, during the drawing process, at the moment when the pen holder mechanism 6 stops sliding in the X direction, the free end 9
A rolling phenomenon occurs due to inertial force. This horizontal shaking phenomenon causes the pen 4 to shift the original position where the recording paper 2 is plotted, thereby reducing plotting accuracy. Therefore, conventionally, by forming the slider 8 of the free end portion 9 using plastic, this slider 8 and the table surface 3
This increases the frictional force between the vehicle and the vehicle to suppress the rolling phenomenon.

Problems with the Background Art In an X-Y plotter in which one end of the pen holder mechanism is a free end, the free end also moves up and down as the pen moves up and down. However, in the case where the slider 8 is provided at the free end, a striking sound is generated when the slider 8 hits the table surface 3 as the slider 8 hits the upper and lower ends of the blank end, and this impact noise occurs during drawing. There is a problem in that the continuation of the sound generates extremely loud vibration noise. Particularly, when the slider 8 is made of plastic, the horizontal shaking phenomenon of the free end is suppressed, but this does not solve the problem of reducing vibration noise.

Furthermore, there is also a drawback that the table surface 3 is scratched by sliding of the slider 8 on the table surface 3.

Purpose of the Invention The present invention has been made in view of the above-mentioned points, and it improves drawing accuracy by suppressing the horizontal shaking phenomenon on the free end side, and also reduces the vibration noise generated due to the vertical movement of the free end side. The purpose is to obtain an X-Y plotter that can be sufficiently suppressed.

Summary of the Invention The present invention provides a pen holder mechanism part whose one end is slidably held in the X direction and extends in the Y direction on a table surface, and a pen holder that holds a pen vertically movably in the pen holder mechanism part. 5. A rubber roller that is slidably held in the Y direction is rotatably provided on the free end side of the pen holder mechanism section and contacts the table surface, and the rubber roller is rotated within a range that does not slip between the pen holder mechanism and the table surface. Since it is equipped with a braking mechanism that suppresses the rotation of the roller, it is possible to suppress the horizontal shaking phenomenon on the free end side, and the vibration noise generated due to the vertical movement of the free end side can be sufficiently suppressed because the roller is a rubber roller. It is composed of

Embodiment of the Invention An embodiment of the invention will be described with reference to FIGS. 2 and 3. Components that are the same as those in the conventional example are designated by the same reference numerals and explanations will be omitted. On the table surface 3, the pen holder mechanism part 11 is
It is provided to extend in the direction. A drive end 7 is formed at one end of this pen holder mechanism section 11, and a free end 12, which is a free end, is formed at the other end. Furthermore,
A pen holder 10 is held in the pen holder mechanism section 11 so as to be slidable in the Y direction.

On the other hand, a rubber roller 13 that comes into contact with the table surface 3 is rotatably attached to the free end 12, and a spring 1 serves as a braking mechanism that suppresses the rotation of the rubber roller 13.
4 are provided. That is, a mounting wall 15 is formed at the free end 12, and a mounting hole 16 is formed in the mounting wall 15.
is formed.

Thus, the spring 14 is fitted into the support shaft 18 having the shaft hole 17, the ring 19 is fitted into the support shaft 18, and the roller hole 20 formed in the rubber roller 13 is inserted into the support shaft 18.
8 is fitted. Thus, the mounting screw 21 is inserted into the shaft hole 17, and the inserted mounting screw 21 is screwed into the mounting hole 16.

In such a configuration, when the mounting screw 21 is tightened, the spring 14 is further shortened and the biasing force against the rubber roller 13 is strengthened, so that the rotation of the rubber roller 13 is further braked. On the other hand, if you loosen this mounting screw 21, the rubber roller 13
becomes easier to rotate.

Utilizing this, adjustment is made so that the rotation of the rubber roller 13 is braked with an optimum force within a range where no slip occurs between the rubber roller 13 and the table surface 3. By adjusting the rubber roller 13 in this manner, it is possible to suppress the horizontal shaking phenomenon that occurs in the free end portion 13 when the pen holder mechanism section 11 suddenly stops during drawing.

Moreover, since the rubber roller 13 is in contact with the table surface 3, even if the free end 12 moves up and down as the pen 4 moves up and down, the vibration noise that may be generated at that time is significantly suppressed.
Moreover, it does not damage the table surface 3.

Effect of the invention This invention is constructed as described above.

The rubber roller whose rotation is braked suppresses the horizontal shaking phenomenon of the free end side of the pen holder mechanism, maintaining high drawing accuracy, and since the rubber roller is in contact with the table surface, the free end does not move up and down. Also, the generation of vibration noise is significantly suppressed, and drawings can be made without damaging the table surface.
