  When the power plug of the main body 2 is plugged into a commercial power supply, the microcomputer 10 is reset to power on at step S501 and then is initialized to an operating state at step S502 as shown in FIG. 5A.

  Next, in step S503, it is determined whether or not a normal operation has been input. That is, in step S503, it is determined whether a predetermined operation in the normal mode (a mode for sucking dust or the like into the main body 2) has been performed on the operation unit 6. Here, when it is determined that a predetermined operation in the normal mode is performed on the operation unit 6, the process proceeds to step S <b> 512, while it is determined that a predetermined operation in the normal mode is not performed on the operation unit 6. If YES, go to step S504.

  In step S512, the microcomputer 10 enters the normal mode. If it does so, the said microcomputer 10 will operate the electric blower 3 via the electric blower control part 11, will output a signal to the display and alerting | reporting part 9, and will alert | report by LED or a buzzer. At this time, the microcomputer 10 ignores any information in the data transmitter / receiver 14. That is, the microcomputer 10 does not accept all signals from the data transmitter / receiver 14.

  In step S504, it is determined whether or not a predetermined T1 second has elapsed since the initial setting after the power-on reset. If it is determined that a predetermined T1 second or more has elapsed since the initial setting, the process proceeds to step S512, and it is determined that a predetermined T1 second or more has not elapsed since the microcomputer 10 enters the normal mode. If YES, the process proceeds to step S505.

  In step S505, it is determined whether or not a special operation has been input. That is, in step S505, it is determined whether or not a predetermined operation in the data transmission / reception mode (mode in which the microcomputer 10 transmits / receives data to / from the external transmission / reception device 27 via the data transmission / reception unit 14) is performed on the operation unit 6. To do. If it is determined that a predetermined operation in the data transmission / reception mode has been performed on the operation unit 6, the process proceeds to step S 506, while it is determined that a predetermined operation in the data transmission / reception mode has not been performed on the operation unit 6. Then, the process returns to step S503.

  As the predetermined operation in the data transmission / reception mode, for example, there is a special operation that is difficult to consider in normal use, such as double pressing of an input key.

  In step S506, the microcomputer 10 is set to the data transmission / reception mode, and the user is notified of the fact that the microcomputer 10 is in the data transmission / reception mode by a display on the display / notification unit 9 or a buzzer sound.

  Next, in step S507, the microcomputer 10 starts data exchange work with the dust detection apparatus 7 via the data transmission / reception unit 14.

Data is sent to the light emitting unit 21 of the dust detection device 7 via the data transmission / reception unit 14, and control data to be written in the storage unit 12 is received from the light receiving unit 22 of the dust detection device 7 via the data transmission / reception unit 14. Thereby, the control data in the said memory | storage part 12 can be read to the external transmission / reception apparatus 27, or the control data in the memory | storage part 12 can be rewritten.

  Next, in step S509, the communication status between the microcomputer 10 and the external transmission / reception device 27 is notified to the user.

  More specifically, when data communication between the microcomputer 10 and the external transmission / reception device 27 is normally performed, the LED of the display / notification unit 9 blinks. When the data communication is not normally performed, that is, when the abnormal data communication is performed, the LED of the display / notification unit 9 is turned on more rapidly than when the data communication is performed normally. While blinking, the buzzer of the display / notification unit 9 is continuously sounded. Further, when the data communication is normally completed, the LED of the display / notification unit 9 is turned on, and the buzzer of the display / notification unit 9 is turned on twice (for example, the buzzer is ON for 0.2 seconds and the buzzer is OFF for 0.2 seconds). .. Buzzer ON for 2 seconds). Thereby, the user can confirm whether the data communication between the microcomputer 10 and the external transmission / reception apparatus 27 was normally performed.

  Next, whether or not a normal signal is input from the dust detection device 7 to the data transmission / reception unit 14 for a predetermined T2 seconds or more, such as no signal is input from the dust detection device 7 to the data transmission / reception unit 14 in step S510. Determine whether or not. If it is determined that a normal signal is not input from the dust detection device 7 to the data transmission / reception unit 14 for a predetermined T2 seconds or more, the process proceeds to step S511, while a normal signal is transmitted from the dust detection device 7 to the data transmission / reception unit 14. Is determined not to be input for a predetermined T2 seconds or more, the process returns to step S506.

  In step S511, the microcomputer 10 resets the software and exits the data transmission / reception mode, and then returns to step S502.
