Abstract

[Object]

[Solving Means] An underlay body includes a surface on which a writing medium is placed, and a sensor that detects a pressure distribution on the surface.

Claims

1. An underlay body, comprising:

a surface on which a writing medium is placed; and

a sensor configured to detect a pressure distribution on the surface.

2. The underlay body according to claim 1,

wherein the sensor includes

a conductive layer having flexibility,

an electrode layer, and

a plurality of structures that separate the conductive layer and the electrode layer from each other, and

the electrode layer includes a plurality of first electrodes and a plurality of second electrodes intersecting the plurality of first electrodes.

3. The underlay body according to claim 1,

wherein the writing medium includes concavities and convexities onto which identification information of the medium is recorded, and

the underlay body further comprises

a processing section configured to acquire the identification information from the pressure distribution onto which the concavities and convexities are reflected.

4. The underlay body according to claim 1, further comprising

a storage section configured to associate and store identification information of the medium and format information of the medium in association with each other.

5. The underlay body according to claim 4,

wherein the storage section stores the format information of the medium and handwriting information detected by the sensor in association with each other.

6. The underlay body according to claim 1, further comprising

a controller configured to judge whether the writing medium is placed on the surface, based on the pressure distribution detected by the sensor.

7. The underlay body according to claim 6,

wherein the controller switches from a second mode to a first mode when the writing medium is placed on the surface, and switches from the first mode to the second mode when the writing medium is removed from the surface.

8. The underlay body according to claim 6, further comprising

a display apparatus provided on the surface,

wherein the controller turns off display of the display apparatus when the writing medium is placed on the surface and turns on the display of the display apparatus when the writing medium is removed from the surface.

9. The underlay body according to claim 1, further comprising

a controller configured to judge that a sheet including a first surface having a plurality of keys and a second surface having concavities and convexities is placed on the surface on which the writing medium is to be placed, from the pressure distribution onto which the concavities and convexities are reflected, and controls an input operation according to the plurality of keys.

10. The underlay body according to claim 1, further comprising

a controller configured to judge an exchange of the writing medium with respect to the surface, based on the pressure distribution detected by the sensor.

11. The underlay body according to claim 1, further comprising

a controller configured to detect writing with respect to the writing medium placed on the surface, based on the pressure distribution detected by the sensor.

12. The underlay body according to claim 11,

wherein the controller outputs a sound effect in accordance with the detection of the writing.

13. The underlay body according to claim 12,

wherein the controller changes the sound effect in accordance with writing pressure of the writing.

14. The underlay body according to claim 1, further comprising

a controller configured to judge writing by a writing tool and erasing by an erasing tool with respect to the writing medium placed on the surface, based on the pressure distribution detected by the sensor.

15. The underlay body according to claim 1, further comprising

a processing section configured to correct a deviation of handwriting information accompanying an arrangement'"'"'s deviation of the medium placed on the surface, based on the pressure distribution detected by the sensor.

16. The underlay body according to claim 1, further comprising

a storage apparatus configured to store handwriting information detected by the sensor.

17. The underlay body according to claim 1, further comprising

a communication section configured to transmit handwriting information detected by the sensor to an external apparatus.

18. The underlay body according to claim 1, further comprising

a processing section configured to generate character data or image data from handwriting information detected by the sensor.

19. The underlay body according to claim 1, further comprising

a processing section configured to acquire a position and writing pressure of a writing tool when writing is performed on the writing medium placed on the surface, based on the pressure distribution detected by the sensor.

20. The underlay body according to claim 1,

wherein the writing medium is paper.
