On the other hand, when a “sensor sensitivity command” including the current sensitivity level of the pyroelectric sensor 16 set by the sensitivity setting circuit unit 18 of the parent device 10 is received via the wireless communication unit 69 (S115: sensor Sensitivity command reception), the CPU 61 proceeds to the process of S117.
In S117, the CPU 61 displays on the liquid crystal display 53 the current sensitivity level of the pyroelectric sensor 16 set by the sensitivity setting circuit unit 18 of the parent device 10 included in the received “sensor sensitivity command”.

  For example, the CPU 61 displays “SENSOR CAND” on the upper part of the liquid crystal display 53, and two black indicating that the sensitivity level of the pyroelectric sensor 16 is level 2, that is, the detection distance is level 2 in the middle part. A square mark is displayed, and “← → DETECT” indicating that the sensitivity level of the pyroelectric sensor 16 can be adjusted by pressing the left and right arrow marks of the selection button 54B functioning as a sensitivity change button is displayed in the lower part.

Subsequently, in S118, the CPU 61 executes a determination process for determining whether or not the release button 54D is pressed, that is, whether or not the request for changing the detection distance of the pyroelectric sensor 16 is released.
If the release button 54D has not been pressed (S118: NO), the CPU 61 proceeds to the process of S119. In S119, the CPU 61 receives the “detection distance” from the parent device 10 via the wireless communication unit 69. A determination process for determining whether or not a “forced termination command” indicating that “change mode” has been released is executed.

When the “forced termination command” indicating that the “detected distance change mode” is canceled from the parent device 10 (S119: YES), the CPU 61 proceeds to the process of S116.
On the other hand, when the “forced termination command” indicating that the “detected distance change mode” has been canceled has not been received from the parent device 10 (S119: NO), the CPU 61 proceeds to the process of S120. In S <b> 120, the CPU 61 executes determination processing for determining whether or not a “sensor detection command” indicating that a person has been detected from the parent device 10 via the pyroelectric sensor 16 is received via the wireless communication unit 69. To do.

When the “sensor detection command” indicating that a person has been detected via the pyroelectric sensor 16 is received from the parent device 10 (S120: YES), the CPU 61 proceeds to the process of S121. In S121, the CPU 61 turns on the LED 58.
Subsequently, in S <b> 122, the CPU 61 reproduces a detection sound such as “beep” through the speaker unit 67. Thereafter, in S123, the CPU 61 turns off the LED 58, and then proceeds to the processing of S124. Note that the LED built in the dial button 54A may be turned off after being turned on.

  On the other hand, if the “sensor detection command” indicating that a person has been detected via the pyroelectric sensor 16 has not been received from the parent device 10 (S120: NO), the CPU 61 proceeds to the process of S124. In S <b> 124, the CPU 61 executes a determination process for determining whether the left and right arrow marks of the selection button 54 </ b> B functioning as a sensitivity change button have been pressed in order to change the sensitivity level of the pyroelectric sensor 16. The CPU 61 is instructed to increase the sensitivity level of the pyroelectric sensor 16 by one step by pressing the right arrow mark of the selection button 54B once. Further, the CPU 61 is instructed to lower the sensitivity level of the pyroelectric sensor 16 by one step by pressing the left arrow mark of the selection button 54B once.

If the left and right arrow marks of the selection button 54B functioning as a sensitivity change button are not pressed (S124: NO), the CPU 61 executes the processing from S118 onward again.
On the other hand, when the left / right arrow mark of the selection button 54B functioning as a sensitivity change button is pressed (S124: YES), the CPU 61 proceeds to the process of S125. In S <b> 125, the CPU 61 transmits a “sensor sensitivity change command” including the sensitivity level value to be changed and set to the parent device 10 via the wireless communication unit 69.

  For example, the current sensitivity level of the pyroelectric sensor 16 set in the sensitivity setting circuit unit 18 of the parent device 10 included in the “sensor sensitivity command” received in S115 is “level 2”. When the right arrow mark of the selection button 54B is pressed “once”, the CPU 61 transmits a “sensor sensitivity change command” including “level 3” as the sensitivity level value to be changed and set to the parent device 10. In S124, when the left arrow mark of the selection button 54B is pressed “once”, the CPU 61 sends a “sensor sensitivity change command” including “level 1” as the sensitivity level value to be changed and set to the parent device 10. Send to.

  Subsequently, in S126, the CPU 61 uses the “sensitivity setting reception command” indicating that the “sensor sensitivity change command” has been received via the wireless communication unit 69, or the “sensor sensitivity change command” is inappropriate. Waiting for reception of one of the “Reject commands” indicating that the command is received (S126: Else).

  Then, when waiting for reception of either “sensitivity setting acceptance command” or “Reject command” and waiting for a predetermined time or longer (eg, about 5 to 20 seconds or more) (S126: command reception timeout) The CPU 61 proceeds to the process of S116. Alternatively, when the “Reject command” is received from the parent device 10 via the wireless communication unit 69 (S126: Reject command reception), the CPU 61 proceeds to the process of S116.

  On the other hand, when a “sensitivity setting reception command” indicating that the “sensor sensitivity change command” has been received from the parent device 10 via the wireless communication unit 69 (S126: reception of sensitivity setting reception command), the CPU 61 Shifts to the process of S127. In S127, the CPU 61 displays a “reception confirmation display” indicating that the parent device 10 has received the “sensor sensitivity change command” on the liquid crystal display 53, and then executes the processing from S117 onward again.

  For example, the CPU 61 displays “Uketsukimashita” on the liquid crystal display 53 as “reception confirmation display”, and then executes the processes after S117 again.

  On the other hand, if the release button 54D is pressed in S118 (S118: YES), the CPU 61 proceeds to the process of S128. In S128, the CPU 61 ends the process after transmitting a “forced termination command” indicating that the “detected distance change mode” has been canceled to the parent device 10.

As described in detail above, in the facsimile apparatus 1 according to the present embodiment, the CPU 21 of the base unit 10 selects the “detection distance change mode” for changing the detection distance of the pyroelectric sensor 16 by the selection button 14B. When the setting button 14C is pressed, the user moves in a direction away from or toward the base unit 10 to detect the user via the pyroelectric sensor 16 by a detection sound or the like via the speaker 23A. Notification is made (S12: YES to S25). Thereby, the user can easily confirm the distance range detectable by the pyroelectric sensor 16.

  In addition, when the CPU 21 of the parent device 10 receives a “sensor sensitivity change command” including any sensitivity level value of level 1 to level 4 to be changed and set for the pyroelectric sensor 16 from the child device 50, the change is made. The set sensitivity level of the pyroelectric sensor 16 in the sensitivity setting circuit unit 18 is changed and set according to the sensitivity level value to be set (S11: YES to S22). Thereby, the user holds the slave unit 50 in a state where the master unit 10 is set to the “detection distance change mode” and confirms the detection distance of the pyroelectric sensor 16 while checking the selection button 54B of the slave unit 50. By pressing the left and right arrow marks, the detection distance of the pyroelectric sensor 16 can be changed and set.

  In addition, when the user walks with the handset 50 while the base unit 10 is set to the “detection distance change mode”, the pyroelectric current is generated by the lighting of the LED 58 of the handset 50 and the detection sound of the speaker unit 67. It is possible to check the detection distance of the sensor 16 (S120 to S123). For this reason, the user confirms the detection distance of the pyroelectric sensor 16 by turning on the LED 58 of the slave unit 50 and the detection sound of the speaker unit 67, and pressing the left and right arrow marks on the selection button 54B of the slave unit 50. The detection distance of the pyroelectric sensor 16 can be changed and set.

Further, the user can easily set the parent device 10 to the “detection distance change mode” by selecting the “detection distance change mode” with the selection button 54B of the slave unit 50 and pressing the setting button 54C. It becomes possible.
Further, since the CPU 21 can change and set the detection distance of the pyroelectric sensor 16 via the sensitivity setting circuit unit 18, a mechanical member for changing the detection distance of the pyroelectric sensor 16 is not required, and It is possible to reduce the size.

Further, the user can easily confirm the detection distance of the pyroelectric sensor 16 of the parent device 10 by an image via the liquid crystal display 53 of the child device 50, sound via the speaker unit 67, light emission of the LED 58, or the like. It becomes.
In addition, the user can detect the image via the liquid crystal display 13 of the parent device 10, the sound via the speaker 23 </ b> A, the blinking light emission of the backlight of the liquid crystal display 13, or the light emission of the LED incorporated in the dial button 14 </ b> A. It is possible to easily check the detection distance of the pyroelectric sensor 16. Furthermore, since the pyroelectric sensor 16 is a pyroelectric infrared sensor, it is possible to reliably detect the movement of a person.

  In addition, this invention is not limited to the said Example, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.

  For example, the pyroelectric sensor 16 is configured to be mechanically rotated in the vertical direction by a stepping motor, a gear train, or the like, and the CPU 12 controls the driving of the stepping motor via a motor driving circuit. The 16 detection distances may be changed and set. Thereby, the detection distance of the pyroelectric sensor 16 can be changed and set with a simple configuration.
