Next, an example of use of the display device 310 shown in FIG. 14 will be described. The user draws the image 30 on the touch panel 370 using the ink of the stationery P. Thus, the image 30 is formed on the touch panel 370 of FIG. 16, and the processing unit 600 sends the image data S3 corresponding to the image 30 to the LCD controller 358 via the system bus 350. The VRAM 360 temporarily records the image data S3. The display panel 312A
The display image 30G can be displayed based on the data in the RAM 360. In this manner, the user can display the image 30 directly on the touch panel 370 using ink, and can surely confirm the contents of the image 30 with eyes. To erase the image 30, the ink on the touch panel 370 may be removed with a cloth or the like.

In the embodiment of the present invention, when taking in an image of a character or the like, a touch panel is used instead of using a scanner. Normally, a plastic pen is used to input data on a screen that has the function of a touch panel on a display device. Handwriting input of an image such as a character can be performed only by using the character.

When an image is input by handwriting, in the embodiment of the present invention, stationery such as a pen based on ink or the like can be used as it is. As a result, feedback with normal ink can be expected, and the handwriting input with a feeling different from the conventional product that presupposes a pseudo pen made of plastic etc. which is clearly different from the writing comfort of a normal pen etc. It can be realized.

In the above-described embodiment, an example in which the linear sensor is mainly moved manually is shown. However, the present invention is not limited to this, and the linear sensor may be linearly moved automatically by a motor. Further, the configuration of the touch panel unit is not limited to the configuration described above, and other examples can be adopted. In the illustrated example, the image display unit, the image recording unit, and the like are folded through the connection unit. However, the present invention is not limited to this, and the image display unit, the image recording unit, the image capture unit, and the like are integrated without providing the connection unit. It may be what you did.
