When all the settings are completed, the user can use the touch panel 1339 ⁇ OKJ. By operating the button, the CPU 11 stores the input restriction setting in the storage unit 15 and executes the restriction processing.
- FIG. 19 and FIG. 20 are flowcharts showing the procedure of the restriction process according to the present invention.
- the CPU 11 receives an input of an e-mail address to which image data is to be transmitted from the operation unit 13 (step S191). Specifically, the CPU 11 displays the destination name from the address data file 15 2 on the display unit 14 as shown in FIG. 4 and accepts the selection of the destination or as shown in FIG. A screen for directly inputting the e-mail address is displayed on the screen and accepts the input of the e-mail address.
- the form shown in FIG. 11, that is, the form for directly inputting an e-mail address will be described.
- the CPU 11 determines whether or not the transmission uniform is set by referring to the storage unit 15 and setting the restrictions described in FIG. 16 (step S 192).
- the CPU 11 sets the e-mail address according to the setting of the restriction described in FIG. Then, it is determined whether or not it is time to input the address (step S193). If the CPU 11 determines that the storage time is set in the storage unit 15 when the determination is made when the e-mail address is input (YES in step S193), the CPU 11 reads the limited range (step S19). Four ) . That is, the CPU 11 stores the setting of the limit range set in FIG. Read from 5 (step SI94).
- step S195 the CPU 11 executes a restriction process.
- the details of the restriction process will be described later.
- CPU 11 determines that the restriction is not determined when entering the e-mail address.
- step S193 that is, when the CPU 11 determines that the time when the limitation is determined is the time when the image data is transmitted is stored in the storage unit 15, the CPU 11 determines that the reading unit 19 To scan the original
- Step S 1910 The CPU 11 stores the digital data of the image data converted by the A / D conversion unit (not shown) in the image memory 151 (step S 1911). Subsequently, the CPU 11 reads the limited range (step S 1912), and executes the limiting process (step S 1913).
- Fig. 21 and Fig. 22 are flowcharts showing the subroutine of the restriction processing.
- CPU11 Does the restricted range read out correspond to the item "Only addresses including the registered domain"? It is determined whether or not it is (step S201). That is, the CPU 11 determines whether or not the user has restricted the transmission range to the e-mail address including the domain registered in the transmission permission address file 153 in the restriction setting wizard shown in Fig. 16. to decide. If the CPU 11 determines that the restriction range is the item “only addresses including the registered domain” (YES in step S201), the CPU 11 determines the domain registered from the transmission-permitted address file 153. Read (step S202).
- step S201 determines that the restricted range is not the item "only address including the registered domain” (1 ⁇ 0 in step S201.
- CPU 11 "Only addresses that include the registered domain and the domain of the receiving address" Judgment is made (step S203). If the CPU 11 determines that the restricted range is the item ⁇ only the address including the registered domain and the domain of the reception address '' (YES in step S203), In other words, the CPU 11 sets the domain registered in the transmission permission address file 153 and the reception address registration file as the transmission range in the restriction setting wizard shown in Fig. 16. It is determined whether or not the restriction is set to the e-mail address including the domain of the Internet facsimile apparatus 1 registered in the Internet facsimile apparatus.
- step S.203 When it is determined that the restriction range is the item “only addresses including the registered domain and the domain of the receiving address” (YES in step S.203), if the CPU 11 is a transmission permitted address file 15 The registered domain is read from step 3 (step S204). Further, the CPU 11 reads the domain registered in the reception address registration file 154 (step S205). If it is determined in step S203 that the restricted range is not the item "registered address only including the domain and the domain of the receiving address" (NO in step S203), the CPU 1 1 reads out the domain registered in the reception address registration file 154 (step S206).
- the CPU 11 determines whether the read domain matches the domain of the e-mail address input from the operation unit 13 (step S207). If the CPU 11 determines that they match (YES in step S207), it sets the flag “1” in RAM 12 (step S208), and if it determines that they do not match (step S208). (NO in step S207), the flag "0" is set in RAM12 (step S209): Then, the CPU 11 returns the processing to the main routine.
- step S196 in FIG. 19 the CPU 11 determines whether or not it is within the limit range (step S196). I.e. C PU 11 determines whether the flag set in RAM 12 is “1” or “0”. If it is determined that the value is not within the limit range (NO in step S 196), that is, if CPU 11 determines that flag “0” is set in RAM 12, as shown in FIG. The CPU 11 displays a warning screen on the display unit 14 (step S197).
- step S196 if it is determined that the value is within the limit (YES in step S196), that is, if the CPU 11 determines that the flag “1” is set in the RAM 12 and If it is determined that the transmission limit is not set in Step 192 (No in Step S192), the CPU 11 drives the reading unit 19 to read the original (Step S199) ).
- the CPU 11 stores the digital data of the image data converted by the AD converter (not shown) in the image memory 15 1
- the CPU 11 also determines the force within the limit range in step S 19 14 (step S 19 14) ⁇ That is, the CPU 11
- step S 1914 CPU 11 determines / determines that flag ⁇ 1 ”is set in RAM 12. ⁇ , and step S 199 or later, CP
- U 11 sends the image data stored in image memory 15 1 to the input e-mail address' (step S 1916).
- Industrial applicability As described above in detail, in the present invention, a partial address common to a plurality of addresses among unique addresses addressed to data transmission such as an e-mail address is stored in the storage unit. register. Then, the data transmission device restricts data transmission to only addresses including the partial address registered in the storage unit. That is, since data is transmitted only to addresses having the same domain, the transmission range is limited within the same workplace or the like, so that security can be strengthened.
- an address is received from input means for inputting an address of a transmission destination.
- the data transmission device accepts only the address including the partial address registered in the storage unit from the input unit.
- the data transmitting device stores the receiving address allocated to itself for receiving data, and further stores a partial address of the receiving address. Register in the storage unit. Then, the data transmitting device restricts the data transmission to only the address including the address and the part of the receiving address registered in the storage unit. As a result, the transmission range is limited to only an address having a partial address of the reception address of the data transmission device itself, and as a result, security can be further enhanced. Can provide excellent effects.
