Abstract

PROBLEM TO BE SOLVED: To provide an input pad device with which the frequency of erasing operation on a display panel is reduced and operability similar to the description with pencil or pen is provided. SOLUTION: When a pressing surface forming a texture 31 on a 1st electrode sheet 3 is pressed by a magnetic pen 1, the position data of contact between the 1st electrode sheet 3 and a 2nd electrode sheet 4 are inputted from the magnetic pen 1 to a host system and at the same time, magnetic force generated by the magnetic pen 1 is operated so that magnetic particles in dispersion liquid 51 can be attracted to the position proximate to the side of 2nd electrode sheet 4. Therefore, a display panel 5 displays the track of different color at the section, where the magnetic particles are made proximate, and when the magnetic pen 1 is separated from the 1st electrode sheet 3, the magnetic force of magnetic pen 1 is not operated. Thus, the magnetic particles are attracted in the direction proximate to the side of magnetic panel 6, the track of magnetic pen 1 is gradually erased, and the input operation can be continued without performing any erasing operation.

And a display panel 5 enclosing a dispersion liquid 51 of magnetic particles disposed on the bottom surface of the second electrode sheet 4,
Coordinate data was input by pressing the electrode sheet 3 with the magnetic pen 1, and at the same time the locus of the magnetic pen 1 was displayed on the display panel 5, but the display on the display panel 5 remained until the erase operation was performed. For example, in the case of continuous input of characters, an erasing operation is frequently repeated.
