In FIG. 21, reference numeral 1101 denotes a main body of the information display apparatus. Reference numeral 1402 denotes an electronic pen with a scanner. Reference numeral 1403 denotes a document to be read.

FIG. 21 shows the reading unit 1107 of the electronic pen 1402 with a scanner as a “how to reduce dust” on the document 1403.
Is read from the left end to the right end of the sentence. At this time, the transport unit 1306 is
The light emitting unit 1301 emits light when the transport of the light 402 is sensed. After the image is read and binarized according to the light emission, the image is stored in the storage unit 1304.

FIG. 22 shows a state in which one point on the information display device 1401 is pointed by the pen tip of the electronic pen 1402 with a scanner. At this time, the input panel 1201 senses an input from the electronic pen 1402 with a scanner and sends a request signal to the pen scanner interface 1212.
Interface 13 in electronic pen 1402 with scanner
05 controls the storage unit 1304 according to the request signal, and outputs the image signal in the storage unit 1304. On the other hand, the input panel 1201 sends coordinate information indicating the position pointed to by the pen tip to the display control unit 1205. Display control unit 12
05 is coordinate information and pen scanner interface 121
2, and rasterizes the image signal, and outputs a control signal for the liquid crystal panel 1206.

As described above, according to the fifth embodiment, inputting additional information to digitized information can be performed more easily by providing the electronic pen with a scanner function.

The present invention can be applied to a system composed of a plurality of devices (for example, a host computer, an interface device, a reader, a printer, etc.), but it can be applied to a single device (for example, a copying machine, a facsimile machine). Etc.).

[0100]

As described above, according to the present invention,
An information display device capable of easily inputting and managing additional information to digitized information can be provided.
