When a button for selecting the network printer 7 provided on the operation panel 5 is turned on, a password is set, and the execution button is pressed, the handwritten image data of the electronic blackboard device 1 is transmitted to the network printer 7. .

Reference numeral 8 denotes an information recording device connected to the electronic blackboard device 1 via a LAN line.
The electronic blackboard device 1 has a storage medium (hereinafter referred to as a memory unit) for recording and storing the read handwritten image data, and by accessing the information recording device 8 connected to the network, the information recording device Data is recorded at 8 predetermined URL addresses.
The handwritten image data recorded in the information recording device 8 is read by designating a URL address by another personal computer (not shown) connected to the network.

The configuration of the information processing apparatus 6 is shown in FIG.
The information processing device 6 controls various functions of the IC card reader 3 and the electronic blackboard device 1 that read data recorded on the IC card 4 when the IC card 4 approaches the IC card reader 3 by a predetermined distance. Control unit 10, scan processing unit 11 that reads an image written on the writing surface with a reading device, memory unit 12 that records written image data, and network unit that transmits the written image data to network printer 7 and information recording device 8 13 includes an operation button 15 for saving handwritten image data and operating the printer, and password setting means 8.

When the IC card 4 is held over the IC card reader 3, the IC card reader 3 supplies power to the IC card 4 by electromagnetic induction, and wireless communication between the IC card 4 and the IC card reader 3 is started.
When wireless communication is started, authentication data and destination address data recorded on the IC card 4 are read by the IC card reader 3 and authentication is performed.
If it is confirmed that the authentication number is correct, the IC card reader 3 outputs a scan start signal to the control unit 10.
Based on the scan start signal, the control unit 10 outputs a scan control signal to the scan processing unit 11 and transfers the writing sheet.
In the scan processing unit 11, the reading device scans the writing sheet surface and reads the writing image in accordance with the transfer of the writing sheet.

The scanning unit 11 includes an illumination device and a reading device.
The reading device includes an illumination device including a light source and a light guide, and a photosensor array in which three photosensor blocks in which photosensor elements are arranged in the vertical direction are arranged in the vertical direction. Each output of each optical sensor block is connected to an analog switch.
The outputs of the three analog switches connected to the three photosensor blocks are connected to the control unit 10.
On the other hand, the light source of the lighting device is connected to an LED driver.

The light source of the lighting device includes a red light emitting LED, a blue light emitting LED, and a green light emitting LED. Each of these LEDs is caused to emit light alternately by an LED driver, and the light enters the light guide. The writing surface 2 arranged adjacent to the light guide is illuminated uniformly in a longitudinal strip shape.
The writing on the writing surface uniformly illuminated by the illuminating device is read by each photosensor element of the photosensor array arranged adjacent thereto.
When the above-described authentication of the IC card 4 is performed, the writing surface 2 is transferred, and the writing on the writing surface 2 is sequentially read by the reading device in synchronization with the transfer.
When reading of one writing surface is completed, the transfer of the writing surface 2 stops.

The read analog handwritten image output is digitized by the analog / digital conversion means sequentially for each emission color in synchronization with the lighting of the red, blue and green LEDs provided in the above-described reading device. The analog output is a signal that is 2.5 volts at the maximum when reflected in white.
The digitized read data is transferred to the memory unit 12 and recorded, and is transmitted to the information recording device 8 via the network unit 13.
In the case of a normal electronic blackboard device, read data of 2000 * 3000 in width is created.

The information recording device 8 is an FTP server, and handwritten image data is recorded for each area designated by the URL address recorded on the IC card 4.
The user of the handwritten image data can view the recorded image data by specifying the URL address.

The authentication data and the destination URL address are encrypted and recorded on the IC card 4. For this reason, the IC card reader 3 has a built-in encryption decoder. As described above, since the authentication data and the address of the destination URL are encrypted, for example, even when the IC card 4 is stolen, the authentication data and the destination URL address can be decrypted. This is impossible and the security of the written image data is ensured.
Further, the image data can be transmitted and recorded to a predetermined storage location by simply holding the IC card 4, so that it is not erroneously transmitted to the wrong place.
In addition, since the transmission destination is determined by the IC card 4, the written image data can always be transmitted and recorded in the same predetermined place even when using the electronic blackboard devices installed in a plurality of places. Become.

An operation panel 5 as shown in FIG. 3 is also provided for users who do not have the IC card 4.

When the main body printer button 15 which is the operation button 15 for printing is operated, the read handwritten image data is sent from the output interface to a printer (not shown) and printed on A4 size paper.

When the network printer button 15 is pressed, a password input is waited. Here, when the user arbitrarily inputs a two-digit number using the numeric keypad 14 of the password setting means, 00 is preceded by the two-digit number. A 4-digit password with the 2-digit number added is created.
When the execution button 16 is pressed after inputting the two-digit password, the same operation as described above is performed, and the written image on the writing surface is read. Thereafter, the read data read by the network printer 7 and the 4-digit password set by the password setting means are transmitted.
In this case, printing is started when the user inputs the above-mentioned four-digit password at the network printer 7.

In the network printer 7, on the operation panel, a 4-digit number obtained by adding a 2-digit number of 00 to the previous 2-digit password number is input as a password.
By using a two-digit password on the electronic blackboard device 1 side, it is easier to memorize it than to enter a four-digit password. And never forget your password.
Also, because the password input on the network printer 7 side is 4 digits, it is more confidential than a 2-digit password, and it is only necessary to enter a fixed number 00, so you forget the password. Can be prevented.

If the network printer 7 is provided with an IC card reader, the URL and password of the network printer 7 may be recorded on the previous IC card 4.
In this case, when the IC card 4 is held over the IC card reader 3, the written image on the writing surface is read, and the written image data and the password recorded on the IC card 4 are transmitted to the network printer 7.
Thereafter, when the user holds the IC card 4 over the IC card reader of the network printer 7, printing is started.

When the save button 15, which is an operation button 15 for recording on a removable USB memory, is operated, the image-processed handwritten image data is transferred and recorded from the output interface to a USB memory (not shown). .
When the net button 15 is pressed and a storage destination address is input, the handwritten image data is transmitted to the information recording device 8 via the network.
