Abstract

A control unit of an image reader executes OCR (optical character recognition processing) on image data as a result of scanning a setup guide, and upon acquiring an SSID and an encryption key, attempts to communicate with a corresponding wireless LAN master device using the SSID and the corresponding encryption key.

First claim

What is claimed is:

1. An image reader comprising:
a scanning unit configured to read an original document provided with an image and convert the image into image data;
a display unit;
a control unit configured to control the reading of the image by the scanning unit; and
a wireless communication unit using a wireless LAN and acquiring one or more SSIDs receivable from wireless devices, wherein
the control unit is configured to execute optical information recognition processing on the image data,
the control unit is configured to cause the scanning unit to read an original document provided with wireless setup information allocated to a wireless LAN master device, to execute the optical information recognition processing on image data of the wireless setup information read, to recognize predetermined information, and to acquire wireless setup information for connection to the wireless LAN master device based on the predetermined information acquired, and
the control unit causes the display unit to display an SSID, which does not match the SSID included in the wireless setup information optically recognized but has characters partially matching those of the SSID included in the wireless setup information optically recognized, from the one or more SSIDs.

2. The image reader according to claim 1 , wherein
the control unit causes the display unit to display a screen that prompts the reading, by the scanning unit, of the wireless setup information of the wireless LAN master device.

3. The image reader according to claim 2 , wherein
The control unit causes, upon acquiring an SSID receivable by the wireless communication unit based on the wireless setup information acquired, the display unit to display the SSID acquired and causes, upon acquiring the one or more SSIDs, the display unit to display a screen that prompts selection of one SSID from the one or more SSIDs displayed on the display unit.

4. The image reader according to claim 1 , comprising a touch panel, wherein
the control unit causes the touch panel to display a start button for starting the reading of the wireless setup information of the wireless LAN master device by the scanning unit.

5. The image reader according to claim 1 , wherein
the wireless setup information includes the SSID and an encryption key.

6. The image reader according to claim 1 , comprising a storage unit configured to store information, wherein
the control unit causes the storage unit to store, when wireless connection with the wireless LAN master device is successful, character information in the wireless setup information of the wireless LAN master device.

7. The image reader according to claim 1 , wherein
the control unit determines whether wireless LAN connection is available at time of startup and executes a wireless connection setup mode when the wireless LAN connection is not available.

8. A method of setting wireless setup information for an image reader being configured to execute optical information recognition processing on image data and including:
a scanning unit configured to read an original document provided with an image and convert the image into image data; and
a wireless communication unit using a wireless LAN, the method comprising:
by the scanning unit, reading an original document provided with wireless setup information allocated to a wireless LAN master device;
executing optical character recognition processing on image data of the wireless setup information optically recognized, to recognize character information provided;
acquiring wireless setup information for connection to the wireless LAN master device based on the character information acquired;
acquiring one or more SSIDs receivable from wireless devices; and
displaying an SSID, which does not match the SSID included in the wireless setup information optically recognized read but has characters partially matching those of the SSID included in the wireless setup information optically recognized, from the one or more SSIDs.
