By the way, when downloading print data in advance by detecting the approach of the user's mobile terminal device 14 using Wi-Fi (registered trademark) or Bluetooth (registered trademark) communication, if printing data is downloaded in advance, If there is, the mobile terminal device may not be detected.

On the other hand, UWB wireless communication has higher transparency than Wi-Fi (registered trademark) or Bluetooth (registered trademark), so it may detect a user's mobile terminal device across a wall, causing false detection of the user. There are cases where this happens.

Therefore, in this embodiment, by detecting the user's mobile terminal device 14 using two types of wireless communication, it is possible to detect false detections due to obstructing objects compared to the case where the user is detected using one type of wireless communication. Reduce.

Specifically, when a user who owns a mobile terminal device 14 having UWB wireless communication and low-transmission wireless communication functions approaches the image forming device 12, the user's mobile terminal device 14 uses UWB wireless communication. Detects the approach of 14.

Then, when the distance to the user detected by UWB wireless communication is less than a predetermined first threshold or within a predetermined low-transmission wireless communication detection range, the low-transparency wireless communication is used to detect the user's mobile terminal device 14.

Note that the print data may be downloaded from the server 16 when the distance at the mobile terminal device 14 detected by UWB wireless communication becomes less than or equal to a predetermined second threshold.

To describe a specific example with reference to FIGS. 5 to 8, the image forming apparatus 12 according to the present embodiment detects a mobile terminal device 14 owned by a user within a UWB detection range 80, as shown in FIG. . FIG. 5 shows an example in which there is no user within the UWB detection range 80.

Here, as shown in FIG. 6, when the mobile terminal device 14 owned by the user is detected in the UWB detection range 80, the image forming device 12 downloads the detected user's print data from the server 16. Start. FIG. 6 shows an example in which a user within the UWB detection range 80 is detected. Alternatively, downloading of the print data may be started when the distance to the mobile terminal device 14 detected by UWB wireless communication becomes less than or equal to a predetermined second threshold.

Subsequently, as the user approaches the image forming apparatus 12, as shown in FIG. When the communication detection range 82 is reached, the approach of the user's mobile terminal device 14 is detected by low-transmission wireless communication. FIG. 7 is a diagram illustrating an example in which a user is detected by low-transmission wireless communication. Note that the predetermined threshold value defines, for example, a distance corresponding to the low-transmission wireless communication detection range 82.

As shown in FIG. 8, when the user approaches a predetermined print start range 84 where the communication strength of low-transparency wireless communication exceeds a predetermined strength threshold, the image forming apparatus 12 is switched from the power saving state. It returns to print standby mode. FIG. 8 is a diagram showing an example in which the user approaches the print start range 84.

Next, a case where there is a shield in the UWB detection range 80 will be described with reference to FIGS. 9 to 11. FIG. 9 is a diagram illustrating an example where there is a shield 86 within the UWB detection range 80. Further, FIG. 10 is a diagram showing an example in which there is a shielding object 86 within the UWB detection range 80 and a user approaches the low-transmission wireless communication detection range 82. Further, FIG. 11 is a diagram showing an example in which there is a shielding object 86 within the UWB detection range 80 and the low-transmission wireless communication is blocked by the shielding object 86 even if the user approaches within the low-transmission wireless communication detection range 82. It is.

As shown in FIG. 9, when the user approaches the image forming apparatus 12 from the shielding object 86 side, when the user's mobile terminal device 14 is detected in the UWB detection range 80, the same as in the case where the shielding object 86 does not exist. The image forming apparatus 12 starts downloading the user's print data from the server 16.

However, even if the distance to the mobile terminal device 14 is less than a predetermined first threshold or within the low-transmission wireless communication detection range 82, the low-transmission wireless communication is blocked by the shielding object 86. Therefore, as shown in FIG. 10, in low-transparency wireless communication, the user's mobile terminal device 14 is not detected, and there is no possibility of erroneously determining that the user is approaching.

Next, specific processing performed by the image forming apparatus 12 in the information processing system 10 according to the present embodiment configured as described above will be described. FIG. 12 is a flowchart illustrating an example of the flow of processing performed by the image forming apparatus 12 in the information processing system 10 according to the present embodiment. Note that the process in FIG. 12 starts, for example, when the mobile terminal device 14 is detected through UWB wireless communication.

In step 100, the CPU 20A issues a response instruction to the mobile terminal devices 14 around the image forming apparatus 12 using UWB wireless communication, obtains the number of responses N and a terminal ID for identifying the mobile terminal device 14, and proceeds to step 102. Transition.

In step 102, the CPU 20A determines whether the number of terminals in the mobile terminal device 14 is N>0. If the determination is affirmative, the process moves to step 104, and if the determination is negative, the series of processing ends.

In step 104, the CPU 20A extracts the difference from the ID list of the previous iteration (last time of processing), and proceeds to step 106. That is, the difference between the mobile terminal device 14 detected this time and the mobile terminal device 14 detected during the previous processing is extracted.

In step 106, the CPU 20A determines whether there is a user who has moved outside the UWB detection range. If the determination is affirmative, the process moves to step 108; if the determination is negative, the process moves to step 110.

In step 108, the CPU 20A discards the target user's print data after a predetermined period of time has elapsed, and proceeds to step 110. That is, if print data of a user who has moved outside the UWB detection range has been downloaded from the server 16 in step 116, which will be described later, the print data is discarded.

In step 110, the CPU 20A determines whether print data of the terminal ID of the mobile terminal device 14 existing within the UWB detection range 80 exists in the server 16. If the print data exists in the server 16 and the determination is affirmative, the process moves to step 112, and if the print data does not exist in the server 16 and the determination is negative, the series of processes is directly terminated.

In step 112, the CPU 20A assigns priorities A to users whose distance to the mobile terminal device 14 for which it has been confirmed that the print data exists on the server 16 is closest, and proceeds to step 114.

In step 114, the CPU 20A determines whether downloading of the print data of priority A has been completed. If the determination is negative, the process moves to step 116; if the determination is affirmative, the process moves to step 118.

In step 116, the CPU 20A downloads the print data of the mobile terminal device 14 with priority level A, and proceeds to step 118.

In step 118, the CPU 20A measures the strength of the low-transmission wireless communication of the mobile terminal device 14 of priority A, and proceeds to step 120. That is, when the distance to the mobile terminal device 14 detected by UWB wireless communication is equal to or less than the predetermined first threshold or reaches the predetermined low-transmission wireless communication detection range 82, the distance to the mobile terminal device 14 detected by the low-transparency wireless communication is detected. Detects approach and measures radio strength.

In step 120, the CPU 20A determines whether the wireless strength of the low-transmission wireless communication is equal to or higher than a predetermined strength threshold. If the determination is affirmative, the process moves to step 122, and if the determination is negative, the series of processing ends.

In step 122, the CPU 20A performs energy saving recovery processing and proceeds to step 124. Here, the energy saving recovery process will be explained with reference to the drawings. FIG. 13 is a flowchart illustrating an example of the flow of energy saving recovery processing.

In step 200, the CPU 20A determines whether or not it is in a power saving state. If the determination is affirmative, the process moves to step 202, and if it is negative, the process moves to step 124 in FIG. 12.

In step 202, the CPU 20A outputs a return command to the image forming control section 34, and the process proceeds to step 124 in FIG.

In step 124, the CPU 20A determines whether user authentication has been completed. This determination is made, for example, by determining whether or not the user authentication short-range wireless communication unit 70 has completed authentication. The process waits until the determination is affirmative and moves to step 126.

In step 126, the CPU 20A starts printing and ends the series of processes. That is, printing is performed on paper by controlling the image forming control section 34.
