In this case, since the destination card and the personal card can be read simultaneously, it is possible to further reduce the time required for address input necessary for mail transmission.

  Next, a second embodiment of the process at the time of mail transmission by the multifunction device 1 will be described. FIG. 6 is a flowchart showing a second embodiment of processing at the time of mail transmission by the multifunction device 1, and FIG. 7 is a diagram showing an example of a document on which serial information is described. In the second embodiment, as shown in FIG. 7, a document on which serial information is described is read by the image reading unit 110, the serial information is extracted from the read image data, and is stored in association with the image data. In addition, when serial information is input to the multi-function device 1 to specify image data to be transmitted later, the image reading unit 102 converts the image data associated with the serial information to image data. The data is read from the storage unit 171 and sent to the designated destination address by mail.

  When a document is set on the image reading unit 110 (YES in S11), the control unit 103 causes the image reading unit 110 to read an image of the document (S12). The information extraction unit 101 extracts serial information from the read image data using an OCR function or the like (S13). For example, when the information extraction unit 101 detects a character of “serial No.” from the read image data, the serial information is extracted from a series of symbols such as numbers and alphabets. Recognize as information. The control unit 103 stores the read image data in the image data storage unit 171 and stores the extracted serial information in the serial information storage table in association with the image data (S14).

  The data transmission / reception unit 180 receives a mail transmission instruction including a transmission source address, a destination address, and serial information for specifying image data to be transmitted from any of the client PCs 31 to 34 connected to the network. Then (YES in S15), the image reading unit 102 reads image data corresponding to the serial information included in the received mail transmission instruction from the image data storage unit 171 (S16). The control unit 103 adds the transmission source address received in S15 to the image data read out by the image reading unit 102 (S17), and sends the data transmission / reception unit 180 to the destination address received in S15. Then, the image data read by the image reading unit 102 is transmitted (S18).

  Until the data transmission / reception unit 180 receives a mail transmission instruction including a transmission source address, a destination address, and serial information from any of the client PCs 31 to 34 connected to the network (NO in S15), S11 to The process of S14 is repeated, and the operation of storing the image data associated with the serial information is executed.

The address and serial information are extracted, and the image data indicated by the serial information is read from the image data storage unit 171 by the image reading unit 102, and the control unit 103 adds the extracted transmission source address and extracts the destination. The data transmission / reception unit 180 transmits the mail to the address.

  When a document is set on the image reading unit 110 (YES in S21), the control unit 103 causes the image reading unit 110 to read an image of the document (S22). Then, the information extraction unit 101 executes processing for extracting a transmission source address, a destination address, and serial information from the read image data by an OCR function or the like. For example, the information extraction unit 101 detects characters of “transmission source address”, “destination address”, and “serial No.” from the read image data. When this is done, a series of symbols such as numbers and alphabets that follow is recognized as a source address, a destination address or serial information, or written in a rectangle marked at a predetermined position on the document surface. A series of symbols such as numbers and alphabets are recognized as a source address, a destination address, or serial information.

  Here, when only serial information is extracted from the read image data (YES in S23), the control unit 103 uses the extracted serial information and the read document image data as the image data storage unit 171 and The data is stored in the serial information storage table 172 (S24). The image data stored in the image data storage unit 171 is the image data from which the image portion indicating the serial number is removed, and the extracted serial number is stored in the serial information storage table 172 in association with the image data. It is preferable to do so.

  When serial information, a transmission source address, and a destination address are extracted from the read image data (NO in S23, YES in S25), the image reading unit 102 stores the image corresponding to the extracted serial information. Data is read from the image data storage unit 171 (S26). The control unit 103 attaches the extracted transmission source address to the image data read by the image reading unit 102 (S27), and sends the data transmission / reception unit 180 to the image of the other party address. The image data read by the reading unit 102 is transmitted (S28).

  In addition, when neither the serial information extraction nor the serial information, the transmission source address and the destination address is extracted from the read image data (NO in S25), normal scanning (the read image) is performed. The control unit 103 receives the read image data from the image memory 120 or the image data storage unit 171. (S29).

  By performing the above processing, the operator performs an operation of transmitting the serial information, the transmission source address, and the destination address from the client PCs 31 to 34 to the multifunction device 1 or manually inputting them to the multifunction device 1. The information necessary for mail transmission can be input to the multifunction device 1 without any problem.
