It is a side view which shows an example of the assembly of the remote control operation part in the remote control device for agricultural machines of this invention.

  A mode for carrying out the present invention will be described.

  FIG. 1: shows the figure in Example 1 of the remote control operating device for agricultural machines of this invention, (a) is a front view of remote control operation part 30A, (b) is a side view of remote control operation part 30A, (c) is The schematic rear view including the block diagram of remote control operation part 30A is shown.

  As shown in FIG. 1, the remote control operation unit 30 </ b> A has an operation panel 31 on the front surface (front), and includes a wireless power reception unit 35 </ b> A, a battery 201, a transmission / reception unit 301, and a remote control operation unit control unit 302. , A control unit power supply / voltage adjustment unit 303 and a switching unit 304.

  The operation panel 31 includes a power button 32a, an operation button 32b, and an indicator lamp 33. The power button 32a and the operation button 32b are the operation buttons 32 that are operation switches, and the operation buttons 32b form a number necessary for the operation of the agricultural machine mounted on the tractor. Note that a side surface of the remote control operation unit 30A has a gradient unit 380 that forms a gradient in a direction in which the area decreases toward the surface. This can be formed using, for example, a draft angle of resin.

  The power button 32a is provided on the upper portion of the operation panel 31, and by pressing the button, the power of the remote control operation unit 30A can be turned from OFF (OFF) to ON (ON), or from ON to OFF. At this time, it is also possible to turn on the power by pressing it for a certain period of time (for example, within a few seconds) so that the power is not turned on by mistake.

  The operation button 32b is a switch for operating a device on the farm work machine 2 side such as an actuator 23 of the farm work machine 2 to be described later, and a plurality of buttons are arranged as necessary. For example, the safety can be enhanced by operating the actuator 23 only while the operation button 32b is being pressed.

  The indicator lamp 33 is arranged at an easily understandable position on the operation panel 31, and is arranged beside the power button 32a in FIG. The indicator lamp 33 can be applied to notify the power supply state, communication state, and battery capacity. Specific examples will be described later.

  The wireless power receiving unit 35A transmits power to and from a wireless power feeding unit 41A described later, and is installed at a position for that purpose. For example, it is preferable that the remote control unit 30A be installed near the surface on the back surface of the remote control unit 30A so as to face the wireless power supply unit 41A when the remote control unit 30A is attached to a power supply holder 100A described later. Further, since the battery 201 is disposed in the first embodiment, the wireless power receiving unit 35A is disposed so as to avoid it. In FIG. 1, a battery 201 is on the left side and a wireless power reception unit 35A is on the right side below the remote control operation unit 30A when viewed from the back.

  The battery 201 is a primary battery, and a commercially available dry battery can be used. Here, the battery 201 can be replaced. In the first embodiment, the battery 201 cannot be charged. The battery 201 only needs to be charged and cannot be charged, but a charged rechargeable battery may be used.

  The transmission / reception unit 301 wirelessly transmits an operation signal from the operation button 32 to the wireless transmission / reception unit 21 on the agricultural machine 2 side under the control of the remote control operation unit control unit 302. In addition, if necessary, the transmission / reception unit 301 can wirelessly receive information from the control unit 22 on the agricultural machine 2 side from the wireless transmission / reception unit 21 and send the information to the remote control operation unit control unit 302.

  The remote control operation unit control unit 302 is configured by a CPU or the like and controls the remote control operation unit 30A, and causes the transmission / reception unit 301 to transmit information from the operation buttons 32 as an operation signal. It is also possible to provide the control unit power supply / voltage adjustment unit 303 integrally.

  The control unit power supply / voltage adjustment unit 303 adjusts the voltage for the remote control operation unit control unit 302. When the output voltage differs between the battery 201 and the wireless power receiving unit 35A, the voltage is adjusted to substantially the same voltage as the control unit voltage. For example, it is assumed that the voltage of the battery 201 is low and the voltage from the wireless power receiving unit 35A is high. In this case, the voltage from the battery 201 is boosted (for example, 1.5 V to 3.0 V), Adjustment is performed by stepping down the voltage from the wireless power receiving unit 35A (for example, 6.0 V to 3.0 V). Further, the control unit power supply / voltage adjustment unit 303 may also have a function of rectifying the alternating current received by the wireless power receiving unit 35A into a direct current. Note that this rectification function can also be provided in the wireless power receiving unit 35A or the switching unit 304.

  Furthermore, the power supply / voltage adjustment unit 303 for the control unit can have an instantaneous power failure prevention function. If the power supply from the wireless power receiving unit 35A is interrupted due to some cause (such as when the wireless power receiving unit 35A and the wireless power feeding unit 41A are deviated), the switching unit 304 cannot switch to the battery 201 in time and the power is interrupted. there is a possibility. At this time, when the power of the remote control operation unit 30A is turned off, the operator has to wait for the power to be turned on again by turning on the power button 32a. The instantaneous power failure prevention function is a function for preventing this. For example, a temporary power storage function such as a capacitor (capacitor) is attached and power is stored therein. When the power from the wireless power receiving unit 35A is interrupted, the power is immediately supplied to the remote control operation unit control unit 302 from the temporary power storage function. In the meantime, switching to the battery 201, or if the power from the wireless power receiving unit 35A is restored within a certain time, the power supply from there can be continued. Note that the instantaneous power failure prevention function may be provided in the remote control operation unit control unit 302.

  The switching unit 304 switches between using the battery 201 as a power source and using the power from the wireless power receiving unit 35A as a power source. The switched power is supplied to the control unit power supply / voltage adjustment unit 303. The switching by the switching unit 304 includes detection by a switch or a circuit.

  When the switching unit 304 is a switch, the remote control operation unit 30A is provided with a switch, and the operator switches the switch. The switch shape is appropriately selected. For example, a slide switch may be provided beside the remote control operation unit 30A. However, in the case of a switch, there is a need for the operator to operate the switch by judging according to the situation (whether a remote control unit 30A is mounted on a power supply holder 100A described later).

  When the switching unit 304 is detected by a circuit, if power supply from the wireless power receiving unit 35A is detected on the circuit, the power from the wireless power receiving unit 35A is given priority, and the remote control operation is performed via the control unit power / voltage adjusting unit 303 The circuit is switched so as to be supplied to the department controller 302. On the other hand, when it is detected that there is no power supply from the wireless power receiving unit 35A, the circuit is switched so that the power from the battery 201 is supplied to the control unit power supply / voltage adjustment unit 303. In the case of detection by a circuit, it can be automatically switched immediately.

  2A and 2B are diagrams illustrating the remote control device for agricultural machinery according to the first embodiment of the present invention, in which FIG. 2A is a front view showing a state where the remote control operation unit 30A is mounted on the power supply holder 100A, and FIG. Is a side view of the power supply holder 100A mounted, and FIG. 5C is a front view of the power supply holder 100A.

  The power supply holder 100 </ b> A has a plate-like overall back surface 110 formed with convex portions and side portions (151, 152, 153, 154, 155) formed toward the front side around the back surface portion 110. Have. These can be formed of, for example, a resin.

  A plurality of convex portions are formed so as to protrude from the back surface portion 110 to the side to which the remote control operation portion 30A is attached. The convex portions are formed in the shape and number necessary to support the back surface of the remote control operation portion 30A. In the example of the figure, the first convex portion 121, the second convex portion 122A, and the two convex portions are formed from the upper side. Is formed. At this time, the wireless power feeding portion 41A is installed in the lower second convex portion 122A (inside) and connected to the harness portion 43. The wireless power feeding unit 41A is positioned so as to face the wireless power receiving unit 35A when the remote control operation unit 30A is attached to the power supply holder 100A. In the figure, it is arranged on the lower left side when viewed from the front. The harness portion 43 extends downward from the second convex portion 122A, and extends outward from the side surface portion (lower side surface portion 155) through the groove 170.

  The side surface portion is provided to hold the side surface of the remote control operation unit 30A. In the illustrated example, the side surface portion is formed by an upper side surface portion 151, an upper side surface portion 152, an inclined portion 153, a lower side surface portion 154, and a lower side surface portion 155, and when the remote control operation unit 30A is mounted, It has a shape along the periphery of the remote control operation unit 30A. Furthermore, the plurality of protrusions 161 and 162 provided on the side surface portion can hold the remote control operation portion 30A so as not to fall from the power supply holder 100A to the front surface side (forward direction). In the example shown in the figure, a first protrusion 161 provided inward on the upper side surface portion 151 and a second protrusion 162 provided inward on the lower lateral side surface portion 154 are provided.

  The upper side surface 151 is a side surface formed on the upper surface side of the remote control operation unit 30A, and the first protrusion 161 is formed. For this purpose, a certain height required, for example, half the thickness of the remote control operation unit 30A is formed. It has a height up to a higher position.

  The upper lateral side surface 152 is a side surface formed on the upper lateral side of the remote control operation unit 30A, and has a low height so that the remote control operation unit 30A can be easily taken out. Specifically, it is formed at a height up to a position that is lower than half the thickness of the remote control operation unit 30A.

  The lower lateral side surface portion 154 is a side surface formed on the lower lateral side of the remote control operation portion 30A, and the second protrusions 162 are formed on each side, and a certain height necessary for this purpose, for example, the thickness of the remote control operation portion 30A. It has a height up to a position higher than half the height. An inclined portion 153 is formed between the upper side surface portion 152 and the lower side surface portion 154.

  The lower side surface portion 155 is a side surface formed on the lower surface side of the remote control operation portion 30A, and is formed at a constant height like the lower horizontal side surface portion 154 so that the remote control operation portion 30A does not shift downward. Further, the lower side surface portion 155 is formed with a groove 170 which is a notch opening to the front surface side, so that the harness portion 43 can pass outward.

  The power supply holder 100A has a back surface extension 111 above the back surface 110 (from the upper side surface 151), and has a mounting hole 141 in the back surface extension 111, and the mounting hole 141 is hooked on a hook. Thus, it can be installed at a suitable place of the tractor 1 such as near the driver's seat. Other methods include a method of attaching the back surface portion 110 with a magnet or a double-sided tape, a method of attaching other attachment holes, and the like.

  In addition, a notch portion formed on the side surface or the back surface of the power supply holder 100A may be provided to form a hole for discharging when the soil adhering to the remote control operation portion 30A accumulates in the power supply holder 100A.

  The other end of the harness portion 43 opposite to the wireless power feeding portion 41 </ b> A side is connected to the power connector 44 and also connected to the external connector 46 via the wiring 45.

  The power connector 44 is a connector that can be detachably connected to a connection portion from a power source included in the tractor. For example, it is possible to connect to a power supply connection portion 12a as an external power supply connected from a battery 11 included in the tractor 1 described later in FIG. At this time, when the connecting portion 12a of the tractor 1 conforms to the Nichiko standard, the power connector 44 can have a connector shape defined by the Nichiko standard.

  The wiring 45 is a wiring branched from the power connector 44 separately from the wiring of the harness portion 43, and is connected to the external connector 46.

  The external connector 46 is a detachable connector for connecting to another output device. By making it the same as the shape in the power supply connection part 12a from the power supply which the tractor 1 has, it can connect to the connector of the output device which can be connected to the power supply connection part 12a.

  It is possible to transmit power wirelessly between the wireless power feeding unit 41A and the wireless power receiving unit 35A. Examples of wireless power feeding include “electromagnetic induction”, “magnetic resonance”, and “microwave / laser light”. The “electromagnetic induction” method is a method in which electric power is transmitted from the primary side coil to the secondary side coil by electromagnetic induction. The “magnetic resonance” method is a method of transmitting power using resonance. The “microwave / laser light (wireless)” system performs power transmission using microwaves or laser light. The wireless power feeding unit 41A and the wireless power receiving unit 35A are configured to match the selected method.

  In the state of FIGS. 2A and 2B, the remote control operation unit 30A is attached to the power supply holder 100A. The back side of the remote control unit 30A is in contact with the first and second convex parts 121 and 122A of the back unit 110, and the front side (front direction) of the remote control unit 30A is the first projection 161 and the first projections. 2 is caught by the protrusion 162 and held. The holding by the protrusions 161 and 162 is stopped by hooking the first protrusion 161 in the middle of the gradient part 380 on the upper side of the remote control operation part 30A. Further, the second protrusion 162 is hooked and stopped in the middle of the slope portion 380 on the lower side surface of the remote control operation portion 30A.

  2A and 2B, when the operator takes out the remote control operation unit 30A from the power supply holder 100A, the operator holds the power supply by holding the side of the remote control operation unit 30A near the upper lateral side surface 152 having a low height. Pull out from the holder 100A to the surface side (forward direction). At this time, the first projection 161 and the second projection 162 are pushed along the gradient portion 380 and slightly deformed by the elasticity of the upper side surface portion 151 and the lower lateral side surface portion 154, so that the first projection 161 and the second projection 162 The remote control operation unit 30A can be pulled out over the protrusion 162. Further, when the remote controller 30A is attached to the power supply holder 100A, it can be attached over the first protrusion 161 and the second protrusion 162 by the elasticity of the upper side part 151 and the lower lateral side part 154.

  FIG. 3 is a schematic plan view showing an example of the arrangement of the tractor and the farm work machine to which the remote control device for farm work machine of the present invention is applied. The present invention can be applied to an agricultural machine 2 that is attached to the tractor 1 and performs agricultural work. The tractor 1 has a battery 11, and the agricultural machine 2 has a wireless transmission / reception unit 21, a control unit 22, and an actuator 23. The battery 11 can be used as a power source for the tractor 1.

  An external power supply harness 12 is connected to the battery 11, and the tip of the battery 11 is a power supply connection portion 12a via a switch 12b. The power supply connection part 12a can connect a power supply to an external apparatus. The switch 12b can be shared with the engine start switch of the tractor 1. For example, the switch 12b can be configured as a key switch that is turned on when a key for engine start is rotated. Thereby, useless power consumption when the work by the tractor 1 is not performed can be prevented. In addition, the shape of the power supply connection part 12a can be made into the connector shape prescribed | regulated by the Nichiko standard, for example.

  In the conventional state in which the power supply holder 100A is not connected, a detachable connector is usually provided between the tractor 1 and the agricultural machine 2 in order to cope with a change in the model of the agricultural machine installed in the tractor 1. At this time, the power connection portion 12 a of the external power harness 12 is directly connected to the connector 25 a of the work machine side harness 25.

  On the other hand, when wiring connection on the power supply holder 100A side is performed, the power supply connection portion 12a and the connector 25a are removed, and the power supply connector 44 on the power supply holder 100A side is connected to the power supply connection portion 12a of the external power supply harness 12. The On the other hand, the external connector 46 is connected to the connector 25 a of the work machine side harness 25. Thereby, electric power can be supplied to the power supply holder 100 </ b> A side and the farm work machine 2 side (the wireless transmission / reception unit 21, the control unit 22, the actuator 23, etc.) using the battery 11 as a power source.

  When the operator operates the remote control operation unit 30A, an operation signal from the remote control operation unit 30A is wirelessly sent to the wireless transmission / reception unit 21, and the control unit 22 activates the actuator 23. A specific example of the actuator 23 will be described later. Further, as necessary, information from the control unit 22 may be transmitted from the wireless transmission / reception unit 21 to the remote control operation unit 30A.

  FIG. 4 is a rear view showing an example of the agricultural machine to which the agricultural machine remote control device of the present invention is applied. FIG. 5 is a front view showing an example of a farm machine to which the farm machine remote control device of the present invention is applied. The farm work machine 2 in FIGS. 4 and 5 is a scraping work machine 50 having a folding mechanism. The input work 51 is attached to the tractor 1 and power from the tractor 1 is input via the input shaft 51 to cover the farm work machine 2. The scratching work is performed by rotating the scratching claw inside the 52 and the first leveling body 53. An example of the actuator 23 will be described using the scraping work machine 50.

  The electro-hydraulic cylinder 56 can be expanded and contracted to operate the rotation mechanism 57 to fold the side working portion 55 inward (as shown on the left side in FIG. 5) to shorten the entire width of the scraper 50. . The extended leveling body driving device 60 rotates the extended leveling body 61 around the rotation shaft 61a via the arm 62 and the wire 63 and rotates the extended leveling body 61 outward by rotating the internal motor. You can choose whether to fold inward. The second leveling body driving device 66 rotates the second leveling body 65 via the second leveling body link means 67 and rotates the second leveling body 65 so as to be fixed at the lower side. It is possible to select whether to make a normal scraping state in which the rotation is not fixed.

  The electric hydraulic cylinder 56, the extended leveling body driving device 60 (or its motor), and the second leveling body driving device 66 (or its motor) can be operated as an actuator 23 by operating the remote control operation unit 30A.

  In addition, as an example of the actuator 23, it is not limited to a scraper working machine, but can be widely applied as long as it is an actuator used in a farm working machine that is attached to a tractor and performs farming work.

  FIG. 6 is a flowchart showing an example of control in the remote controller for a farm machine according to the present invention. The control in FIG. 6 is performed by the remote control operation unit control unit 302.

  First, when control is started (S100), it is determined whether or not the power of the remote control operation unit 30A is turned on (S101). If the power is on, the process proceeds to S102, and if not, the process returns to S100. At this time, for example, when a signal that is an ON condition by pressing the power button 32a or the like is detected, the power of the remote control operation unit 30A is turned ON. Also, on the agricultural machine 2 side, when the wireless transmission / reception unit 21 and the control unit 22 are OFF, information is received from the transmission / reception unit 301 and these are turned ON. This power button ON state is a state in which continuous communication is performed between the transmission / reception unit 301 of the remote control operation unit 30A and the wireless transmission / reception unit 21 on the farm work machine 2 side.

  Next, it is determined whether or not wireless power feeding is performed from the wireless power feeding unit 41A via the wireless power receiving unit 35A (S102). The determination in S102 determines that wireless power feeding is being performed, for example, if it can be confirmed that power is obtained from the wireless power receiving unit 35A by detecting an alternating current or the like.

  If it is determined in S102 that wireless power feeding is being performed, the power source of the remote control operation unit 30A remains on (S103), and the DC adapter mode is set (S104). In this state, continuous communication is performed between the transmission / reception unit 301 of the remote control operation unit 30A and the wireless transmission / reception unit 21 on the farm work machine 2 side. At this time, if the operation button 32b is operated, the actuator 23 can be immediately operated with good response. During this control, unlike S111 described later, the standby mode is not entered. For this reason, it is necessary to set the control of S103 and S104 as control different from the control of S111.

  On the other hand, as another control method of the DC adapter mode, there is a control method of continuing the DC adapter mode while utilizing the control of S111 to S113 described later. As one of the standby mode conditions, when the operation button 32 is not operated for a certain period of time, the standby mode is entered. Instead of the signal input by operation of the operation button 32 at a time interval shorter than the certain time, the power signal The control which gives the signal etc. is added and it does not shift to standby mode. In the case of a power signal, for example, a signal having a time shorter than the reaction time is given by continuing to press the power button 32a, and the power is not turned off by this signal, and the standby mode is entered. To prevent.

  This DC adapter mode is continued as long as the power supply of the remote control operation unit 30A is not turned off (S105) and the wireless power feeding is continued (S102). If the power source of the remote control operation unit 30A is turned off by pressing the power button 32a of the remote control operation unit 30A (S106), the process returns to S100.

  On the other hand, also when it is determined in S102 that wireless power feeding is not performed, the power supply of the remote control operation unit 30A remains on (S111). In this state, continuous communication is performed between the transmission / reception unit 301 of the remote control operation unit 30A and the wireless transmission / reception unit 21 on the farm work machine 2 side. At this time, if the operation button 32b is operated, the actuator 23 can be immediately operated with good response. However, when wireless power feeding is not performed, it is assumed that the battery 201 is used as a power source, and thus the amount of power to be supplied is limited. When the battery 201 is not inserted, or when the battery 201 has no capacity, the power button is not turned on, and the power supply of the remote control operation unit 30A is not turned on.

  On the other hand, if the power button is turned off by pressing the power button 32a again while the power is on, the remote control operation unit 30A is turned off (S112, S118). If the power is on as it is, the standby mode condition is determined (S113), and if the condition is met, the standby mode is set (S114).

  The standby mode condition is that the communication between the transmission / reception unit 301 of the remote control operation unit 30A and the wireless transmission / reception unit 21 on the farm work machine 2 side is changed from continuous communication to intermittent communication when the operation button 32 is not operated for a certain time. It is to switch. The intermittent communication in the standby mode performs communication at intervals as compared with the continuous communication in S111, and is, for example, an interval of several seconds to several tens of seconds. By switching to intermittent communication, the consumption of the battery 201 can be suppressed more than when continuous communication is performed.

  To return from the standby mode, when the operation button 32 is pressed during the standby mode, the standby mode condition (S113) is lost, and the intermittent communication is switched to the continuous communication of S111, and normal operation can be performed. However, when switching to continuous communication, it takes some time, and the operator does not feel that the actuator 23 operates with good response. Further, when it is detected that wireless power feeding is being performed during the standby mode, control may be shifted to the DC adapter mode (S113, S102, S103, S104).

  On the other hand, if the power button 32a is turned off by pressing the power button 32a again for a predetermined time or more in the standby mode, the power source of the remote control unit 30A is turned off (S115, S118). On the other hand, if the power is on as it is, the auto power off mode condition is determined (S116), and if the condition is met, the auto power off mode is set, and the remote control operation unit 30A is powered off (S117, S118). If it is determined that the auto power off mode condition is not satisfied, the standby mode is continued if the standby mode condition is met (S116, S113, 114).

  The auto power off mode condition is to set the auto power off mode when the operation button 32 is not operated for a certain period of time. This is the same as when the power is turned off by operating the power button 32a. At this time, the power supply of the remote control operation unit 30A is turned off, and communication between the transmission / reception unit 301 of the remote control operation unit 30A and the wireless transmission / reception unit 21 on the agricultural machine 2 side is not performed. Thereby, the consumption of the battery 201 is extremely small. Further, the reception function of the wireless transmission / reception unit 21 on the farm work machine 2 side can also be turned off, and the control unit 22 may be turned off. The fixed time of the auto power off mode condition is longer than the time for shifting to the standby mode condition, and can be applied, for example, between several minutes to several hours.

  As other auto power-off mode conditions, intermittent communication between the transmitter / receiver 301 of the remote control operation unit 30A and the wireless transmitter / receiver 21 of the agricultural machine 2 side is performed during standby mode (due to the fact that radio waves do not reach). Auto power-off mode may be set when it is not possible for a certain period of time. This is because if it is not possible to communicate with the wireless transmission / reception unit 21 on the agricultural machine 2 side, it is assumed that the operation cannot be performed even after returning from the standby mode. The fixed time in this case is shorter than the fixed time when the operation button 32 is not operated, and is, for example, several minutes to several tens of minutes.

  To return from the auto power off mode, it is necessary to perform an ON operation by pressing the power button 32a. When the power button 32a is pressed (in some cases for a certain period of time), the remote control operation unit 30A is turned on. Also, on the agricultural machine 2 side, when the reception function of the wireless transmission / reception unit 21 and the control unit 22 are turned off, it is necessary to turn them on. For this reason, recovery from the auto power off mode takes longer to start than recovery from the standby mode.

  The standby mode and auto power off mode can be controlled only in the standby mode or only in the auto power off mode.

  As other control, when the voltage of the battery 201 has dropped, the indicator lamp 33 informs the user, and when the voltage drops further, the control for turning off the power of the remote control operation unit 30A may be applied. . This is because the capacity of the battery is lost if the voltage of the battery 201 decreases. For example, the above control is performed when a voltage of about several tens of the rated voltage drops.

  The display of the indicator lamp 33 can be notified of the state by changing the display color or by separately displaying lighting and blinking. For example, when the power of the remote control unit 30A is ON, green is lit, when the radio transceiver unit 21 on the agricultural machine 2 side is in a range where radio waves reach, red is lit, and when the battery capacity is low For example, the red light blinks, and the remote control operation unit 30A is turned off when the power is off.

  With the agricultural machine remote control operation device having the above-described configuration, an operator can operate remotely using the battery 201 as a power source when operating the remote control operation unit 30A without being mounted on the power supply holder 100A. When the power button 32a is pressed, the power is turned on, and the actuator 23 can be operated remotely by the operation button 32b. The remote control operation unit 30A can be freely moved and operated as long as wireless radio waves reach it. In addition, it is possible to reduce the consumption of the battery 201 by controlling so as to shift to the standby mode if there is no operation for a certain period of time and to turn off the power in the auto power off mode if there is no operation for a certain period of time. .

  On the other hand, when the remote control operation unit 30A is attached to the power supply holder 100A, the power from the battery 11 is supplied via the wireless power feeding unit 41A and the wireless power receiving unit 35A. Then, the switching unit 304 switches to power supply from the wireless power receiving unit 35A. At this time, no power is supplied from the battery 201 and the battery is not consumed. And by control, as DC adapter mode, a power supply remains on and it is in the state which can operate the actuator 23 immediately. Further, since the remote control operation unit 30A is held by the power supply holder 100A with a certain force, the remote control operation unit 30A is moved and operated within a certain range (the range where the harness unit 43 reaches) with the power supply holder 100A attached. It is also possible.

  Further, when the remote control operation unit 30A is removed from the power supply holder 100A, the power from the wireless power reception unit 35A is not supplied, so that the switching unit 304 switches to use the battery 201 as a power source.
