Move the pen P to the recording paper S according to the movement in the Y direction.
When the recording paper S is brought into contact with the recording paper S, a figure corresponding to the X-Y movement is drawn on the surface of the recording paper S appearing in the space A. By analogy with manufacturing examples of conventional X-Y plotters, the plotter 10 according to the present invention weighs 1 to 2 kg.
Since the main body 11 can be held and raised and lowered easily, the main body 11 can be easily lifted and lowered, and the weight is optimal for fixing the peripheral portion of the recording paper S. Also,
The recording paper S may be of any type, and cardboard may also be used.

FIG. 3 shows another example of the use of the plotter 10 according to the present invention. FIG. 3 shows an example of use similar to a conventional plotter, in which figures are written over the entire area of a small sheet of paper Sa. Reference numeral 21 in the figure is a pedestal, and this pedestal 2
A bed 21a is formed on the upper surface of 1. The area of this bed 21a is the space A of the plotter 10.
It is set to be the same as or slightly narrower.
A magnetic plate is installed on the bed 21a, and the recording paper placed on the top surface of the magnetic plate is installed on the bed 21a.
