Description

[Detailed explanation of the idea] This invention relates to a recording pen support device for a plotter.

Conventionally, as a support device for a recording pen such as an XY plotter that automatically records information on a secondary plane, as shown in FIG. A configuration is known in which the recording pen D is supported in a cantilever manner and provided with a wheel C at the free end to move the recording pen D in parallel in the X-axis direction.

(In FIG. 1, the arm in the Y-axis direction is the same as the arm in the X-axis direction, so it is omitted.

) In general, the apparatus having the above configuration is used in order to prepare for replacing the recording paper E or to absorb an error in the parallel distance S between the surface of the recording paper E and the arm B.
It is configured to have some dynamic margin in the direction.

Therefore, if the XY plotter is installed in a place where there is a lot of vibration or on a slope, the recording pen may vibrate due to the above-mentioned dynamic margin, or it may not work accurately, making it impossible to draw correct figures. It had

In view of the above, this invention was devised for the purpose of providing a recording pen support device for a plotter that can operate accurately even in a place with a lot of vibration or an inclined place. An idling wheel with the arm as a rotation axis is provided at the free end of an arm that is cantilevered and moves in parallel, and either the free end of the arm or the contact surface of the idling wheel has a magnet, or The other arm is made of a magnetic material, and a slider to which a recording pen is attached is slidably fitted into the arm.

Next, this invention will be explained using examples.

FIG. 2 shows a perspective view of a main part of an embodiment of this invention, in which one end is supported in a cantilever by the plane moving element 1.
An idling wheel 3 with the arm 2 as a rotation axis is provided at the tip of an arm 2 that moves in parallel in the direction, and a permanent magnet 5 is attached to the tip of the arm 2 via a bracket 4. The contact surface 6 of the wheel 3 is formed of a metal plate made of a magnetic material, and the arm 2 is configured such that a slider to which a recording pen is attached is slidably fitted.

Note that the arm 2 that moves in the direction perpendicular to the X direction has the same configuration as the arm 2 that moves in the X direction, so a description thereof will be omitted.

In the above embodiment, the bracket 4 is provided in the extending direction of the arm 4, but as shown in FIG.
It may also be configured such that the permanent magnets 5 are arranged in alignment with the idle wheels 3 in a direction perpendicular to the idling wheels 3 and the permanent magnets 5 are provided at the tips thereof.

Further, in all of the above embodiments, it is necessary to provide a clearance for the bracket 4 in order to ensure a sufficient movement range of the arm 4.

Therefore, in cases where there is no area available to provide clearance for the bracket 4, such as in a small device, the idle wheel 3' itself attached to the free end of the arm 4 may be formed of a permanent magnet as shown in FIG. .

In this case, it is desirable that the N and S poles of the permanent magnet be located at the end faces of the wheel as shown in the figure.

Furthermore, although the above embodiments have all shown cases in which a magnet is provided on the arm side, it is also possible to form a configuration in which the contact surface 6 of the idle wheel 3 is formed of a magnetic plate, and the idle wheel 3 is formed of a magnetic material. good.

Since this device is configured as described above, the arm 4
However, even if the arm 4 is configured to be able to move to some extent in the vertical direction (two directions) around the base, the tip of the arm 4 is attracted toward the contact surface of the wheel by magnetic force. The arm 4 does not move unnaturally, so accurate recording can be performed even in places with a lot of vibration or on an inclined surface, and the installation conditions for using an XY plotter etc. can be greatly relaxed. .
