Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an information reading system that manually reads information such as characters, figures, photographs, etc. and performs various information processing.

<Prior art> Conventionally, when information processing is performed on word processors, personal computers, etc., characters, figures,
Image scanners are used to read image data such as photographs.

<Problems to be Solved by the Invention> By the way, conventional image scanners require a cable between them in order to transfer scanned image data to the main unit of a word processor or personal computer, and to supply power to the image scanner. It is connected.

Therefore, the scanning rotation of the image scanner is physically restricted by the length of the cable, or the cable becomes an obstacle when scanning the image scanner, resulting in inconvenience when reading a desired image.

Means for Solving the Problems> The present invention has been made in view of the above circumstances, and it improves the operability when using an image scanner, and also improves the operability when using an image scanner, and also improves the ease of use when using an image scanner. The purpose is to increase convenience by making it possible to transport only the following items.

Therefore, the information reading system of the present invention includes an image scanner that reads image data on paper, and an IC that stores the image data read by the image scanner.
It consists of a card and a main body device such as a word processor or a microcomputer that executes various information processing based on the image data stored in the IC card. The IC card is provided with a transmitting unit that wirelessly transmits the image data transferred and stored from the image scanner to the main device, and the main device is provided with a reader/writer section that performs the above-mentioned IC card.
The configuration includes a receiving section that receives data from the transmitting section of the card.

Function> In the mtc described above, when image data on a paper is read by an image scanner, this image data is transferred to and stored in an IC card loaded in a reader/writer section of the image scanner. The IC card wirelessly transmits this image data from the transmitter to the main device. The receiving section of the main device receives data sent from the IC card, and executes various information processing based on this image data.

In this way, since data is transmitted between the image scanner and the main device in a cordless manner, the operability of the image scanner is improved.

<Embodiment> FIG. 1 is a block diagram showing the entire information reading system.

It is a main body device such as a word processor or a microcomputer that executes various information processing based on stored image data.

On the other hand, as shown in FIG. 1, the IC card 4 includes a contact section 34 connected to the reader/writer section 22 and the power supply 32 of the image scanner 2, and image data transferred from the image scanner 2 via the contact section 34. A RAM for storing the image data stored in the RAM 36, a transmitting/receiving unit that modulates the image data stored in the RAM 36 and wirelessly transmits it to the main device 6, and receives transmission control data transmitted from the main device 6, and executes various control processes. Equipped with a CPU to

Furthermore, the main device 6 includes a transmission/reception control unit 42 that receives and demodulates the wireless signal transmitted from the transmission section 38 of the IC card 4 and also transmits transmission control data to the IC card 4 wirelessly. is provided. Note that 44 is a CPU provided in the main device 6.

Next, the operation of the information reading system I having the above configuration will be explained with reference to the flowcharts shown in FIGS. 3 and 4.

As shown in FIG. 3, when reading image data with the image scanner 2, the setting switch 26
Operating conditions for data reading are set in advance for U30 (step 2). As this operating condition, processing such as setting a unique label number to the image data to be read in advance is performed.

Next, the CPU 30 checks whether the execution switch 28 is turned on (step (2)), and if the execution switch 28 is turned on, starts reading data (step (2)). Then, as the image scanner 2 scans the paper surface, a synchronization pulse is output from the encoder 12, and the data read by the image sensor lO is transmitted in binary form via the interface 7 in synchronization with this synchronization pulse. The image data is converted into binarized image data by the conversion circuit 18. This image data is then transferred to the CPU 30. The CPU 30 adds a label number preset with the setting switch 26 to the read image data (Step 2), and transfers this image data to the interface 12.
4. Transfer the data to the IC card 4 via the reader/writer section 22 (step ■), and increment the label number by +1 (step ■). Next, it is checked with the setting switch 26 whether reading of the image data is completed or not (step (2)). If continuing reading is set, the process returns to step 26 and reading of the next image data is executed.

Also, if image data reading completion is specified,
Finish the read operation.

On the IC card 4 side, the data transferred from the image scanner 2 is transferred to the RAM 3 via the contact section 34 and the CPU 40.
6.

Data transmission processing to the main device In the main device 6, when the timing to receive image data read by the image scanner 2 comes, the CPU 44
outputs a reception request control signal to the transmission/reception control unit 42. In this case, if it is desired to preferentially receive specific image data among the image data stored in the image scanner 2, the control signal includes a label number code corresponding to the image data.

The transmission/reception control unit 42 receives this control signal, modulates it, and wirelessly transmits it to the IC card 4.

On the IC card 4 side, as shown in FIG.
When the control signal of the reception request is received from (Step 2), it is demodulated by the transmitter/receiver 38 and transferred to the CPU 40 (Step 2). Based on this control signal, the CPU 40 checks whether a request to preferentially transmit image data with a specific label number has been issued from the main device 6 (step @). This is done by determining whether the control signal includes a label number code. When there is a request to preferentially transmit image data to which a label number is attached, the CPU 40 transmits the image data to the RAM 3.
When the label number of the image data stored in 6 is searched (step @), if a corresponding label number exists (step 0), the image data is read from RAM 36 and sent to main device 6 via transmitter/receiver 38. (Step ■). Furthermore, in step @, if there is no request to preferentially transmit image data with a specific label number, the image data with the latest label number is read out and transmitted to the main device 6 (step ■). .

The wireless signal transmitted from the IC card 4 is received by the transmission/reception control unit 42 of the main device 6, demodulated, and then sent to the C
It is taken into the PU44.

<Effects of the Invention> According to the present invention, the data read by the image scanner is transmitted to the main device using an IC card in a cordless manner, so the operability when using the image scanner is improved compared to the conventional method. be done.

Additionally, if you attach a label number to the image data when reading it, you will be able to select and transfer only specific image data from the scanned image data as needed.
Convenience can be improved.
