By inserting a bolt 85 into this through hole 82d and a through hole provided in the mounting plate 71, and screwing a nut 86 (see FIG. 4B) to a bolt tip protruding from the back side of the mounting plate 71, A control box 82 is attached to the attachment plate 71. When the control box 82 is attached to the attachment plate 71, the electronic substrate 100 accommodated in the control box 82 is maintained in a posture substantially parallel to the attachment plate 71. The posture is toward the worker M who is on the traveling machine body 90.

  When the control box 82 is attached to the attachment plate 71, the control box 82 is attached between the flange portion 84 b and the attachment plate 71 via a packing 87. As shown in FIG. 5A, the packing 87 is formed in an annular shape like the flange portion 84b, and is formed in a C shape so that the packing 87 is not interposed in the side plate portion 84 ′ between the pair of insertion holes 84a. ing. For this reason, between the front end of the side plate portion 84 ′ between the pair of insertion holes 84a where no packing 87 is interposed and the mounting plate 71, as shown in FIG. A through-hole 88 that communicates with each other is formed. The through hole 88 allows the moisture in the housing recess 82a to be discharged to the outside. The packing 87 is made of elastically deformable rubber, cork rubber, or the like. The control box 82 is integrally formed of resin, synthetic resin (ABS resin, FRP) or the like, and can transmit a command signal transmitted from the wireless command device 60.

  The electronic board 100 accommodated in the control box 82 includes an antenna 101 that receives a command signal from the wireless command device 60, and an electric hydraulic cylinder 57 (see FIG. 1) according to the command signal received by the antenna 101. A control unit 200 that controls the operation of an actuator such as a drive motor is provided. The antenna 101 is formed on the surface side of the electronic substrate 100, and the length of the antenna 101 is set by the wavelength of the electromagnetic wave transmitted from the wireless command device 60.

  4B is further added to the electronic board 100. A board-side electric wire 103 electrically connected to the control unit 102 is connected to the electronic board 100, and a board-side connector 104 is connected to the tip of the board-side electric wire 103. Is attached. The board-side electric wire 103 extends to the outside of the control box through a through hole 84 a provided in the control box 82, the tip side thereof goes around the lower end outside the mounting plate 71, and the board-side connector 104 is connected to the back surface of the mounting plate 71. It is arranged around the lower end of the side. The board-side connector 104 is connected to a drive-side connector 106 attached to the distal end portion of the drive-side electric wire 105 connected to the actuator.

  The control box 82 attached to the attachment plate 71 is covered with a cover 110 as shown in FIGS. 4 (a) and 4 (b). The cover 110 is configured to cover the top plate portion 83 and the side plate portion 84 of the control box 82 and is detachably attached to the attachment plate 71. The cover 110 has an upper wall portion 111 that covers the top plate portion 83 and side wall portions 112 a and 112 b that extend downward from the outer periphery of the upper wall portion 111.

  The upper wall portion 111 is formed in a planar shape, and extends substantially parallel to the top plate portion 83 in a state where the cover 110 is attached to the attachment plate 71. The side wall 112 a that covers the upper side of the control box 82 among the side walls 112 is locked to the peripheral edge of the mounting plate 71 to which the upper side of the control box 82 is attached. A step 113 is formed at the tip of the side wall 112 a, and the step 113 locks the tip of the side wall 112 a to the peripheral edge of the mounting plate 71.

  Side wall part 112b which covers the lower side of control box 82 among side wall parts 112 has stepped part 114 latched to the peripheral part of mounting plate 71 which attached the lower side of control box 82, and the tip of side wall part 112b The portion extends further downward beyond the mounting plate 71 and surrounds the board side connector 104 and the drive side connector 106. Similar to the control box 82, the cover 110 is integrally formed of resin, synthetic resin (ABS resin, FRP) or the like, and can transmit a command signal transmitted from the wireless command device 60.

  As described above, the electronic board 100 accommodated in the wireless reception control device 70 is placed on the side of the worker who has boarded the traveling machine body 90 in the working state of the tilling work machine 1 as shown in FIGS. Since the posture is maintained, when the worker M who has boarded the driver's seat 91 of the traveling machine body 90 faces the agricultural work machine side, the electronic board 100 in the wireless reception control device 70 faces the worker side. The worker M can operate the wireless command device 60 with the wireless command device 60 facing the electronic substrate 100. For this reason, the radio signal transmitted from the radio command device 60 can be reliably received by the electronic substrate 100.

  Further, the control box 82 of the wireless reception control device 70 has the flange portion 84b attached to the attachment plate 71 via the packing 87, so that the opening portion 82b of the accommodating recess 82a can be liquid-tightly closed with respect to the attachment plate 71. . For this reason, the situation where water intrudes into the accommodating recess 82a from between the flange portion 84b and the mounting plate 71 can be suppressed.

  The electronic board 100 is disposed in the vicinity of the inside of the top plate portion 83 of the control box 82 and extends in the vertical direction along the top plate portion 83, so that the electronic substrate 100 is separated from the mounting plate 71. For this reason, even if water intrudes into the accommodating recess 82a from between the mounting plate 71 and the flange portion 84b, the water flows on the mounting plate 71, so that it is possible to prevent the water from adhering to the electronic substrate 100.

  Further, as shown in FIG. 5A, the lower end of the control box 82 is provided with a through hole 88, so that moisture in the accommodation recess 82 a can be discharged, and water adheres to the electronic substrate 100. The situation to do can be suppressed more.

  Furthermore, as shown in FIG. 4B, the control box 82 is covered with a cover 110 that surrounds the top plate portion 83 and the side plate portion 84, so that water is controlled when the tilling work machine 1 is washed. A situation of adhering to the surface side of the box 82 can be prevented. In addition, since the water flow direction changing plate 79 is provided on the back surface of the mounting plate 71, the water flowing from the upper part to the lower side of the back surface of the mounting plate 71 hits the water flow direction changing plate 79 and falls downward. Further, the lower portion of the cover 110 below the water flow direction changing plate 79 in the cover 110 extends further downward beyond the mounting plate 71. For this reason, even if the water at the time of car wash is poured on the lower back side of the mounting plate 71, the water hits the lower part of the cover 110 and bounces off. Therefore, it is possible to reduce the adhesion of water to wiring components such as the board-side connector 104 and the drive-side connector 106 arranged below the back surface side of the mounting plate 71.

  Now, FIG. 6, FIG. 7 (a) (side view), and FIG. 7 (b) (side view) show the tilling work machine 1 removed from the traveling machine body 90 and held by the caster stand 7. FIG. . The posture of the tilling work machine 1 held by the caster stand 7 is further inclined downward in the vertical direction as compared with the posture during the tilling work (see FIG. 2A). For this reason, the cover 110 covering the control box 82 has a posture extending in a substantially vertical direction, and the electronic board 100 accommodated in the control box 82 is similarly in a posture extending in a substantially vertical direction. Therefore, by operating the wireless command device 60 from the front of the tillage work machine 1 with the electronic board facing toward the electronic board, it is the same as when the operator M who has boarded the driver's seat of the traveling machine body 90 operates the wireless command device 60. In addition, the radio signal transmitted from the radio command device 60 can be reliably received by the electronic substrate 100.

  Even when the posture of the control box 82 extends in a substantially vertical direction, the surface side (the top plate portion side and the side plate portion side) of the control box 82 is covered with the cover 110, and the control box 82 is covered with the packing 87 ( Wiring components such as the board-side connector 104 and the drive-side connector 106 that are attached to the attachment plate 71 via the lower side of the control box 82 and are attached to the attachment plate 71 (see FIG. 5A) (see FIG. 4B). Is still covered by the water flow direction changing plate 79 (see FIG. 4B) and the lower portion of the extended cover 110. For this reason, it is possible to suppress the situation where water enters the control box 82 when the tilling machine 1 is washed, and it is possible to reduce the adhesion of water to the wiring components.

  The power switch 210 is a switch for turning on / off the power source 224 of the remote control device 60. When the power switch 210 is pushed, the power is turned on, and when it is pushed again, the power is turned off. When the power is turned on, the power lamp (LED) 211 is turned on when communication is established in the radio wave range. If communication is not established outside the radio range, a communication error occurs and flashes.

  The left / right changeover switch 212 is a switch for switching between the opening / closing mode of the extension work machine 30 and the opening / closing mode of the second extension leveler 36. The left / right changeover switch 212 switches between opening / closing the extension work machine 30 and left / right operation of the second extension leveler 36. When the switch is pressed, the operation mode can be switched sequentially from left to right, right, left, left and right simultaneously. When the power is turned on, it stands up in the left and right simultaneous mode.

  The left and right mode lamps 213 and 214 turn on the left and right lamps in the left and right simultaneous mode, the right lamp 213 lights in the right mode, and the left lamp 214 lights in the left mode.

  The work machine opening / closing switches 215 and 216 are operated only when they are pressed, and when the extension work machine body 30 is closed and the opening is pushed, the extension work machine body 30 is opened and enters the work state. When the close button is pressed while the extension work machine body 30 is open, the extension work machine body 30 is closed to be in the retracted state. The left / right changeover switch 212 can be opened / closed at the same time on the left and right, only on the right and only on the left.

  The extension leveler opening / closing switches 217 and 218 operate only when pressed, and when the second extension leveler 36 is closed, pressing the open button opens the second extension leveler 36. When the second extension leveler 36 is open, pressing the close button closes the second extension leveler 36.

  The leveler scraping operation switch 220 operates only when it is pressed, and when the scraper is pressed in the soiling state, the leveler 22 and the extension leveler 35 are in the scraping state.

  The communication unit 223 puts command data or ID data stored in the storage unit 222 on the radio wave when each switch is pressed via the antenna 227 and transmits it via the antenna 227. In addition, the communication unit 223 receives a signal from the wireless reception control device 70. When each switch is pressed, the control unit 221 reads command data corresponding to each switch stored in the storage unit 222 and sends the command data to the communication unit 223. When the power switch 210 is pressed, ID data stored in the storage unit 222 is sent to the communication unit 223. The storage unit 222 stores programs and settings used in the control performed by the control unit 221. Further, the storage unit 222 stores ID information, data of commands for operating the electric hydraulic cylinder 57, the drive motor 46, and the rotation device 44. The power source 224 supplies power to the communication unit 223, the control unit 221, and the storage unit 222.

  The output control unit 226 of the communication unit 223 performs control to output at a strength smaller than the strength of the radio wave output when each switch other than the power switch 210 is operated when the power switch 210 is turned on. In particular, when the power switch 210 is turned on, radio waves are transmitted with a first radio wave output, and when operating switches other than the power switch 210, radio waves are transmitted with a second radio wave output. At this time, the intensity of the first radio wave output is smaller than the intensity of the second radio wave output. The intensity data of the first radio wave output and the intensity data of the second radio wave output are stored in the storage unit 222.

  FIG. 11 is a functional block diagram of the control unit 221. The control unit 221 includes a CPU 230, a memory 231, an input unit 232, and an output unit 233. The input unit 232 includes a left / right changeover switch 212, work implement opening / closing switches 215, 216, extension leveler opening / closing switches 217, 218, a leveler shifting switch 219, a leveler scraping work switch 220, and a signal from the communication unit 223. Is entered.

  The output unit 233 outputs signals to the communication unit 223, the power lamp 211, the right mode lamp 213, the left mode lamp 214, and the buzzer 225. The storage unit 231 stores a control program 240 that controls the operation when each switch is pressed, and a startup control program 241 that is executed when the power switch 210 is pressed to start the remote control device 60.

  The storage unit 231 also includes a left switch command data 242 that is a command that is transmitted when the left switch 212 is pressed, and a right switch command data 243 that is a command that is transmitted when the right switch 212 is pressed. Storing work machine open command data 244 which is a command to be sent when the work machine open switch 215 is pressed, and work machine close command data 245 which is a command to be transmitted when the work machine close switch 216 is pressed. Yes.

  Further, the storage unit 231 has the extension leveler open command data 246 that is a command to be transmitted when the extension leveler open switch 217 is pressed, and the extension leveler close that is a command to be transmitted when the extension leveler close switch 218 is pressed. The command data 247, the leveler squeezing switching command data 248 that is transmitted when the leveler squeezing switch 219 is pressed, and the leveler scraping work command data 249 that is transmitted when the leveler scouring work switch 220 is pressed are stored.

  In addition, the storage unit 231 stores first radio wave output intensity data 250, second radio wave output intensity data 251, and ID data 252.

  For example, when the opening 215 of the work implement opening / closing switch 215 is pressed, the CPU 230 reads the work implement open command data 244 stored in the storage unit 231, and the output unit 233 sends the control program 240 to the communication unit 223. The data is transmitted, and the communication unit 223 places the work machine opening command data on the carrier wave and transmits it from the antenna 227. At this time, the CPU 230 reads the second radio wave output data (for example, 10 mW) from the storage unit 231, and the output control unit 226 of the communication unit 223 sets the output of the radio wave to be transmitted to the second radio wave output.

  The communication unit 202 in the wireless reception control device 70 receives and demodulates the radio wave via the antenna 101, sends work machine opening command data to the control unit 200, and the control unit 200 decodes the command data, A work machine open command is executed, the electric hydraulic cylinder 57 is operated via the I / O unit 203, and the extension work machine body 30 is opened and closed. The other switches of the remote control device 60 are operated in the same manner.

  The “start-up control program” 241 is a program that is executed when the power is turned on. When the power is turned on, a command for transmitting radio waves is transmitted from the control unit 221 to the communication unit 223. At that time, first radio wave output data (for example, 2 mW) is sent to the output control unit 226 of the communication unit 223. At this time, the ID data is also placed on the radio wave. As a result, the communication unit 223 transmits the first radio wave output radio wave via the antenna 227. When a reply radio wave from the radio reception control device 70 is not received after a predetermined time, that is, when the radio reception control device 70 does not receive radio waves, the radio reception control device 70 is off, or the ID is different, the power lamp ( LED) 211 blinks.

  When the radio wave reaches the radio reception control device 70, the radio reception control device 70 extracts the ID data from the received radio wave and collates the ID data with the ID data in the storage unit 201. When the ID data does not match, the reply radio wave is not sent, and when the ID data matches, the reply radio wave is sent. When receiving a radio wave from the radio reception control device 70, the remote control device 60 turns on the power lamp (LED) 211.

  As described above, the work machine is controlled by operating the remote control device 60.

  Next, a procedure executed by the startup control program 241 in the remote controller 60 will be described with reference to the flowchart of FIG. The start-up control program is started when the operator turns on the power of the remote control device 60. The control program for the radio reception control device 70 is also started when the radio reception control device 70 is turned on.

Step S <b> 11: The control unit 221 reads ID data from the storage unit 231 and sends it to the communication unit 223.
Step S12: The control unit 221 sends the first radio wave output data of the storage unit 231 to the output control unit 226 of the communication unit 223. The output is controlled from the antenna 227 so as to be output.

Step S13: The control unit 221 determines whether or not a reply radio wave from the wireless reception control device 70 has been received.
Step S14: If the reply radio wave is not received in step S13, the LED 211 blinks.

  Step S15: It is determined whether or not a power-off condition has been met. Here, the power-off condition is whether the power switch is pressed, no operation is continued for a predetermined time (for example, 5 minutes), or key input is continued for a predetermined time (for example, 2 minutes) or more. If it is not a power-off condition, step S13 is executed. If the power-off condition is satisfied, step S25 is executed to turn off the power.

Step S16: The radio reception control device 70 determines whether or not a radio wave from the remote control device 60 has been received. If not received, return. Thus, the reception interrupt process is terminated.
Step S17: If the radio wave from the remote control device 60 is received in step S16, the communication unit 202 extracts the ID data from the received radio wave and sends it to the control unit 200.

Step S19: The control unit 200 determines whether or not the ID data collated in step S18 matches. If the ID data does not match, the process returns. Thus, the reception interrupt process is terminated.

Step S20: If the ID data match in step S19, the control unit 200 transmits a reply radio wave from the communication unit 202. Then, the process returns to end the reception interrupt process.
Step S21: When the control unit 221 of the remote control device 60 receives the radio wave from the wireless reception control device 70 by the communication unit 223, the power lamp (LED) 211 is turned on.

Step S22: The control unit 221 turns on the buzzer 225.
Step S23: The control unit 221 sends the second radio wave output intensity data from the storage unit 231 to the output control unit 226 of the communication unit 223, and the communication unit 223 converts the radio wave output to the second radio wave output intensity by the output control unit 226. To do.

Step S24: It is determined whether or not a power-off condition has been met. Here, the power-off condition is whether the power switch is pressed, no operation is continued for a predetermined time (for example, 5 minutes), or key input is continued for a predetermined time (for example, 2 minutes) or more. If it is not a power-off condition, step S24 is executed again. This establishes a standby state until a power-off condition such as pressing the power switch is established or each switch is pressed.
Step S25: If the power-off condition is satisfied in step S24, the power is turned off and the program is terminated.

  As described above, when the power is turned on, the output radio wave intensity is the first radio wave output intensity of about 2 mW and the radio wave output intensity is small. Even if the radio wave does not reach and the operation command switch is turned on without the operator's intention, it is possible to eliminate the possibility that the operation of the agricultural machine unintended by the worker is executed at the same time as the power is turned on. As a result, it is possible to prevent an unintended operation when the command switch is pressed when the power is on, and to ensure safety.

  Next, the procedure when each switch is pressed will be described with reference to the flowchart of FIG. Here, a case where the opening of the work implement opening / closing switch is pressed will be described as an example. The procedure when the other switches are pressed is different from the command corresponding to each switch, but the procedure is almost the same, so the description is omitted.

Step S31: The control unit 221 checks whether or not the work implement opening / closing switch 215 is pushed by the worker.
Step S32: When the work implement opening / closing switch 215 is pressed, the CPU 230 reads work implement open command data stored in the storage unit 231.

Step S33: The control unit 221 sends the data to the communication unit 222, and the communication unit 223 places the work implement opening command data on the carrier wave and transmits it from the antenna 227. At this time, the output control unit 226 of the communication unit 223 sets the output of the radio wave to be transmitted to the second radio wave output.
Step S34: The communication unit 202 in the radio reception control device 70 determines whether or not the radio wave is received via the antenna 101. If no radio wave is received, the process returns and ends this reception interrupt process.

Step S35: If the radio wave is received in step S34, the communication unit 202 transmits a return radio wave.
Step S36: The communication unit 202 extracts work implement opening command data and sends it to the control unit 200.

Step S37: The control unit 200 stores the command data. Then, the process returns to end this reception interrupt process.
Step S38: The control unit 221 of the remote control device 60 determines whether or not a reply radio wave from the wireless reception control device 70 has been received. If no reply wave is received, return. As a result, the interrupt process is terminated. Then, this program is started after a predetermined time, for example, 10 msec.

  Step S39: If a reply radio wave is received in step S38, reply completion processing such as turning on the buzzer is performed, and the process returns.

  The above processing in the remote control device 60 is repeatedly executed every predetermined time, for example, every 10 msec.

  FIG. 13B is a flowchart of timer interrupt processing executed by the control unit 200 of the wireless reception control device 70 every predetermined time, for example, every 20 msec.

Step S41: The control unit 200 checks the command stored in step S37 and decodes the command. In this embodiment, the fact that the work implement opening command is stored is read out.
Step S42: The control unit 200 executes an operation process. In this embodiment, the control unit 200 executes a work machine opening command, operates the electric hydraulic cylinder 57 via the I / O unit 203, and opens the extension work machine body 30. Then return.
The procedure by other switch operations of the remote control device 60 is executed in substantially the same manner, although the operation is different from the command.

  Next, the remote control device 60 according to the second embodiment of the present invention will be described. In the second embodiment, the radio wave output gradually increases from zero when the power is turned on, and becomes the second radio wave output when communication is established. Only the startup process program is different, and the apparatus configuration is the same as that of the first embodiment. Therefore, only the startup process is described, and other description is omitted.

  FIG. 14 is a flowchart illustrating a procedure executed by the startup control program in the remote control device 60 according to the second embodiment. The start-up control program is started when the operator turns on the power of the remote control device 60. The control program for the radio reception control device 70 is also started when the radio reception control device 70 is turned on.

Step S <b> 51: The control unit 221 reads ID data from the storage unit 231 and sends it to the communication unit 223.
Step S52: The control unit 221 sends the first radio wave output intensity data read from the storage unit 231 to the output control unit 226 of the communication unit 223. The communication unit 223 puts the ID data on the radio wave, and the output control unit 226 Control is performed so that the output intensity gradually increases from zero, and transmission is performed from the antenna 227.

Step S53: The control unit 221 determines whether or not a reply radio wave from the wireless reception control device 70 has been received.
Step S54: If a reply radio wave is not received in step S53, the power lamp (LED) 211 blinks.

Step S55: The output control unit 226 of the communication unit 223 determines whether or not the intensity of the output radio wave has reached the first radio wave output intensity. If it is not the first radio wave output intensity, step S57 is executed.
Step S56: If the intensity of the radio wave output in step S55 is the first radio wave output intensity, the intensity of the output radio wave is kept constant at the first radio wave output intensity.

  Step S57: It is determined whether or not a power-off condition is met. Here, the power-off condition is whether the power switch is pressed, no operation is continued for a predetermined time (for example, 5 minutes), or key input is continued for a predetermined time (for example, 2 minutes) or more. If it is not a power-off condition, step S53 is executed. If the power-off condition is satisfied, step S67 is executed to turn off the power.

Step S58: The radio reception control device 70 determines whether or not a radio wave from the remote control device 60 has been received. If not received, return. Thus, the reception interrupt process is terminated.
Step S59: If the radio wave from the remote control device 60 is received in step S58, the communication unit 202 extracts the ID data from the received radio wave and sends it to the control unit 200.

Step S60: The control unit 200 collates the ID data stored in the storage unit 201 with the ID data from the received radio wave.
Step S61: The control unit 200 determines whether or not the ID data verified in step S18 matches. If the ID data does not match, the process returns. Thus, the reception interrupt process is terminated.

Step S62: If the ID data match in step S61, the control unit 200 transmits a reply radio wave from the communication unit 202. Then, the process returns to end the reception interrupt process.
Step S63: When the control unit 221 of the remote control device 60 receives the radio wave from the wireless reception control device 70 by the communication unit 223, the power lamp (LED) 211 is turned on.

Step S64: The control unit 221 turns on the buzzer 225.
Step S65: The control unit 221 sends the second radio wave output intensity data from the storage unit 231 to the output control unit 226 of the communication unit 223, and the communication unit 223 converts the radio wave output to the second radio wave output intensity by the output control unit 226.

Step S66: It is determined whether or not a power-off condition has been met. Here, the power-off condition is whether the power switch is pressed, no operation is continued for a predetermined time (for example, 5 minutes), or key input is continued for a predetermined time (for example, 2 minutes) or more. If it is not a power-off condition, step S24 is executed again. This establishes a standby state until a power-off condition such as pressing the power switch is established or each switch is pressed.
Step S67: If the power-off condition is satisfied in step S24, the power is turned off and the program is terminated.

  As described above, when the power is turned on, the radio wave output intensity gradually increases from zero to the first radio wave output intensity with a low radio wave output intensity until communication with the radio reception control device 70 is established. Even if the radio reception control device 70 that controls the machine does not receive radio waves and the command switch for operation is turned on without the operator's intention, the operation of the agricultural machine unintended by the operator is executed at the same time as the power is turned on. The possibility of being done can be eliminated. As a result, it is possible to prevent an unintended operation when the command switch is pressed when the power is on, and to ensure safety.

  In the present embodiment, ID data is stored in the storage unit 231 of the remote control device 60, and when the power is turned on, the ID data is put on a radio wave and the ID data of the storage unit 201 of the wireless reception control device 70 is stored. However, the ID data of the remote control device 60 may be set by inputting it by an external operation. As a result, when the remote control device cannot be used due to a failure or the like, another remote control device can be used instead to set the ID data and make it usable.

  FIG. 15 is a functional block diagram of the control unit 300 of the remote control device in which ID data can be set from the outside. As shown in FIG. 15, this remote control device stores ID data in a storage unit 231 and has an ID setting area 301 in which the ID data is written when the power is turned on. In addition, the remote control device includes an ID setting unit 302 for setting ID data in the ID setting area 301 of the storage unit 231 from the outside. Other parts shown in FIG. 15 are the same as those shown in FIG.

  FIG. 16 is a flowchart for explaining the procedure executed by the startup control program in the remote control device in which the ID data can be set. The start-up control program is started when the operator turns on the power of the remote control device 60. The control program for the radio reception control device 70 is also started when the radio reception control device 70 is turned on.

Step S71: The control unit 221 stores the ID data stored in the storage unit 231 in the ID setting area 301.
Step S72: The control unit 221 determines whether or not the ID setting unit 302 has input ID data from the outside. If there is no input of ID data from the outside, step S74 is executed.

Step S73: If ID data is input from the outside in Step S72, the ID data input from the outside is stored in the ID setting area 301.
Step S74: The control unit 221 reads the ID data from the ID setting area 301 and sends it to the communication unit 223.
Step S75: The control unit 221 sends the first radio wave output data of the storage unit 231 to the output control unit 226 of the communication unit 223. The output is controlled from the antenna 227 so as to be output.

Step S76: The control unit 221 determines whether or not a reply radio wave from the wireless reception control device 70 has been received.
Step S77: If no reply radio wave is received in step S13, the power lamp (LED) 211 is blinked.

  Step S78: It is determined whether or not a power-off condition is met. Here, the power-off condition is whether the power switch is pressed, no operation is continued for a predetermined time (for example, 5 minutes), or key input is continued for a predetermined time (for example, 2 minutes) or more. If it is not a power-off condition, step S13 is executed. If the power-off condition is satisfied, step S25 is executed to turn off the power.

Step S79: The radio reception control device 70 determines whether or not a radio wave from the remote control device 60 has been received. If not received, return. Thus, the reception interrupt process is terminated.
Step S80: If the radio wave from the remote control device 60 is received in step S79, the communication unit 202 extracts the ID data from the received radio wave and sends it to the control unit 200.

Step S81: The control unit 200 collates the ID data stored in the storage unit 201 with the ID data from the received radio wave.
Step S82: The control unit 200 determines whether or not the ID data verified in step S81 matches. If the ID data does not match, the process returns. Thus, the reception interrupt process is terminated.

Step S83: If the ID data match in step S82, the control unit 200 transmits a reply radio wave from the communication unit 202. Then, the process returns to end the reception interrupt process.
Step S84: When the control unit 221 of the remote control device 60 receives the radio wave from the wireless reception control device 70 by the communication unit 223, the power lamp (LED) 211 is turned on.

Step S85: The control unit 221 turns on the buzzer 225.
Step S86: The control unit 221 sends the second radio wave output intensity data from the storage unit 231 to the output control unit 226 of the communication unit 223, and the communication unit 223 converts the radio wave output to the second radio wave output intensity by the output control unit 226. To do.

Step S87: It is determined whether or not a power-off condition has been met. Here, the power-off condition is whether the power switch is pressed, no operation is continued for a predetermined time (for example, 5 minutes), or key input is continued for a predetermined time (for example, 2 minutes) or more. If it is not a power-off condition, step S24 is executed again. This establishes a standby state until a power-off condition such as pressing the power switch is established or each switch is pressed.
Step S88: If the power-off condition is satisfied in step S24, the power is turned off and the program is terminated.

  As described above, the ID data of the remote control device 60 can be set by inputting it by an external operation. Therefore, when the remote control device cannot be used due to a failure or the like, another remote control device is used instead. Can be used by setting ID data. Further, in this remote control device, processing is performed according to the procedure shown in FIG. 16. Therefore, when the power supply is turned off after the operation of the remote control device is finished, when the power supply is turned on again, the ID data 303 stored in advance is the ID. It is stored in the setting area 301.
