  The transfer number recognition unit 601 counts the number of times transferred so far. The transfer number adding unit 602 sets an upper limit value of the transfer number by adding information (transfer number information) indicating the transfer number counted by the transfer number recognition unit 601 to the transfer data. In addition, the transfer determination unit 203 compares the count value of the transfer number recognition unit 601 with the upper limit value of the transfer number set by the transfer number addition unit 602, and the transfer number (the count value of the transfer number recognition unit 601). Has not reached the set value (the upper limit value of the transfer count set by the transfer count adding unit 602), it is determined to execute the data transfer process, and the transfer count exceeds the set value. In this case, it is determined not to execute the data transfer process.

Next, in step S703, the transfer count recognition unit 601 counts the number of transfers so far and recognizes the transfer count. In step S704, the transfer count adding unit 602 adds the transfer count and sets an upper limit value of the transfer count.

  In step S705, the transfer determination unit 203 determines whether to transfer data. If it is determined not to transfer data, the process proceeds to step S710 to enter a next job standby state.

  On the other hand, if it is determined in step S705 that data is to be transferred, the process proceeds to step S706, where the transfer count value recognized by the transfer count recognition unit 601 in step S703 is the set value (transfer count adding unit 602). It is determined whether or not the upper limit value set by (1) has been exceeded. Then, it is determined that the value of the transfer count recognized by the transfer count recognition unit 601 exceeds the set value (for example, the transfer count recognized by the transfer count recognition unit 601 is 7 and the set value is 5). In this case, the process proceeds to step S708, display control is performed by the display control unit 206, a warning is displayed on the display unit 207 in the next step S709, and then the process proceeds to step S710 to enter the next job standby state.

  On the other hand, when it is determined in step S706 that the value of the transfer count recognized in step S703 has not reached the set value, the process proceeds to step S707, where the data transmission unit 205 transmits data, and then The process advances to step S710 to enter the next job standby state.

  In the present embodiment, the case where the number of transfers recognized in step S703 is 7 and the set value is 5 has been described as an example. However, the number of comparisons can be arbitrarily set.

  As described above, according to the present embodiment, by setting the setting value of the number of data transfers, it is possible to prevent data transfer from becoming a loop even in the mutual transfer setting of a plurality of information processing apparatuses. It is possible to reduce the load on the device by reducing the load on the network.

 In addition, when the above warning display is performed, when the user performs an operation input to the information processing apparatus or when it is set in advance to permit the transfer even if it is addressed to the own apparatus, the transfer is performed. You may make it perform.

 Further, when the transfer to the own apparatus is not executed as described above, a report or the like indicating that may be printed out.
