The disclosure of Japanese Patent Application No. 2021-083137 filed on May 17, 2021, including specification, drawings and claims is incorporated herein by reference in its entirety.
The present invention relates to an operation apparatus that operates a ship propulsion machine.
A ship is provided with a ship propulsion machine that propels the ship. A console of the ship is provided with a plurality of devices for operating the ship. Examples of the devices provided on the console include a steering device that performs a steering operation of the ship, a remote control device that performs a shift switching operation of the ship propulsion machine and an operation of increasing/decreasing a rotation speed of a power source of the ship propulsion machine, the ship propulsion machine, a gauge device that displays various kinds of information on the ship and navigation, a start switch that starts the power source of the ship propulsion machine, and an emergency stop switch that stops the power source of the ship propulsion machine in an emergency such as when a ship operator falls into water. The following patent literature describes an example of the remote control device.
In order to solve the above problems, the invention is an operation apparatus configured to operate a ship propulsion machine provided in a ship, and the operation apparatus includes: a remote control device including a holder and an operation lever swingably supported by the holder, and configured to perform, by the operation lever, a shift switching operation of the ship propulsion machine and an operation of increasing/decreasing a rotation speed of a power source of the ship propulsion machine; a gauge device including a display device and configured to display, on the display device, information on the ship propulsion machine including information indicating a shift position of the ship propulsion machine and information indicating the rotation speed of the power source; and a case to which the remote control device and the gauge device are each attached, and which integrates the remote control device and the gauge device. In the case, the remote control device and the gauge device are disposed adjacently to each other in a front-rear direction of the ship.
In the related art, the plurality of devices for operating the ship are independent devices, and is separately disposed on an attachment surface of the console. Therefore, an overall attachment area required for attaching these devices to the attachment surface of the console is increased. As a result, when these devices are attached to the console, a large console having a wide attachment surface is required. It is not preferable to increase a size of the console in a small ship.
In addition, when a plurality of independent devices for operating the ship are separately disposed on the attachment surface of the console, an operation area for the ship operator operating the ship is widened, and as a result, a distance for the ship operator moving his/her arm to operate the ship is increased. For example, when the gauge device is disposed on a right side of the steering device and the remote control device is disposed on a right side of the gauge device on the attachment surface of the console, a distance between the steering device and the remote control device increases since the gauge device is disposed between the steering device and the remote control device. Therefore, when the steering operation by the steering device, the shift switching operation by the remote control device, and the like are alternately performed, the ship operator needs to greatly move the right arm in a left-right direction, resulting in poor operability. In addition, while the right arm repeats the great movement in this manner, a cord connecting the right arm of the ship operator and the emergency stop switch may be entangled, and the operability may be further deteriorated.
In addition, when the plurality of devices for operating the ship are separately disposed on the attachment surface of the console, attachment work of attaching these devices to the attachment surface of the console becomes complicated. Specifically, in order to attach the device for operating the ship to the attachment surface of the console, it is necessary to provide a hole through which a fixing member (for example, a bolt) for fixing the device to the attachment surface of the console passes, a hole through which a cable connected to the device passes, and the like in the attachment surface of the console. When the plurality of devices for operating the ship are separately disposed on the attachment surface of the console, it is necessary to provide the hole through which the fixing member passes and the hole through which the cable passes on the attachment surface of the console for each device for operating the ship. Therefore, it is necessary to provide a large number of holes in the attachment surface of the console. As a result, the attachment work of attaching the devices for operating the ship to the attachment surface of the console becomes complicated.
The invention has been made in view of, for example, the above-described problems, and an object of the invention is to provide an operation apparatus capable of reducing an overall attachment area of a plurality of devices for operating a ship, and being excellent in operability or capable of improving attachment workability.
According to the invention, it is possible to reduce an overall attachment area of a plurality of devices for operating a ship, to improve operability, or to improve attachment workability.
An operation apparatus according to an embodiment of the invention is an operation apparatus that operates a ship propulsion machine provided in a ship, and includes a remote control device and a gauge device. The remote control device includes a holder and an operation lever swingably supported by the holder, and the operation lever is used to perform a shift switching operation of the ship propulsion machine and an operation of increasing/decreasing a rotation speed of a power source of the ship propulsion machine. The gauge device is a device including a display device and displaying information on the ship propulsion machine on the display device. The information on the ship propulsion machine includes information indicating a shift position of the ship propulsion device and information indicating the rotation speed of the power source of the ship propulsion machine. The operation apparatus according to the embodiment of the invention further includes a case to which the remote control device and the gauge device are each attached, thereby integrating the remote control device and the gauge device. Further, in this case, the remote control device and the gauge device are disposed adjacently to each other in a front-rear direction of the ship.
According to the operation apparatus of the embodiment of the invention, by attaching the case in which the remote control device and the gauge device are integrated to an attachment surface of a console, the remote control device and the gauge device can be provided on the attachment surface of the console. According to the operation apparatus of the embodiment of the invention, since the remote control device and the gauge device are aggregated into one case so as to be integrated, an attachment area required for attaching this case to the attachment surface of the console can be reduced as compare with an overall attachment area required for attaching the independent remote control device and the independent gauge device separately from each other to the attachment surface of the console. As a result, it is possible to prevent an increase in size of the console.
Further, according to the operation apparatus of the embodiment of the invention, in addition to the remote control device and the gauge device being aggregated via the case so as to be integrated, the remote control device and the gauge device are disposed adjacently to each other in the front-rear direction of the ship, and thus, an operation area for a ship operator operating the ship can be reduced, and a distance for the ship operator moving his/her arm to operate the ship can be reduced.
Specifically, by disposing the operation apparatus according to the embodiment of the invention on the attachment surface of the console on a lateral side of a steering device so as to be close to the steering device, it is possible to reduce a distance between the steering device and the remote control device while providing the remote control device and the gauge device on the attachment surface of the console. That is, in the operation apparatus according to the embodiment of the invention, since the remote control device and the gauge device are disposed adjacently to each other in the front-rear direction of the ship, when the operation apparatus is disposed on the lateral side of the steering device, the gauge device is not positioned between the steering device and the remote control device. Therefore, the distance between the steering device and the remote control device can be reduced by disposing the operation apparatus on the lateral side of the steering device so as to be close to the steering device. When the distance between the steering device and the remote control device is reduced, a distance by which the arm moves to left or right when the ship operator alternately performs a steering operation by the steering device, the shift switching operation by the remote control device, and the like decreases, thereby improving operability. In addition, even when the ship operator repeats the movement of the arm in order to alternately perform the steering operation, the shift switching operation, and the like, the movement of the arm is reduced, and thus a cord connecting the arm of the ship operator and an emergency stop switch is less likely to be entangled.
In addition, according to the operation apparatus of the embodiment of the invention, by attaching the case of the operation apparatus to the attachment surface of the console, the remote control device and the gauge device integrated via the case can be provided on the attachment surface of the console, and thus it is possible to improve workability of attaching the remote control device and the gauge device to the console.
Specifically, in the above-described technique in the related art, since the remote control device and the gauge device are separated from each other, it is necessary to separately attach the remote control device and the gauge device to the attachment surface of the console. In order to each attach the remote control device and the gauge device to the attachment surface of the console, it is necessary to provide, in the attachment surface, a hole through which a fixing member (for example, a bolt) for fixing the remote control device to the attachment surface passes and a hole through which a fixing member for fixing the gauge device to the attachment surface passes. In contrast, in the operation apparatus according to the embodiment of the invention, the remote control device and the gauge device are integrated via the case. Therefore, in order to attach the remote control device and the gauge device to the attachment surface of the console, the attachment surface may be provided with a hole through which a fixing member for fixing the case via which the remote control device and the gauge device are integrated to the attachment surface passes. Therefore, the number of holes provided in the attachment surface of the console for fixing the device can be reduced.
Further, when the remote control device and the gauge device are separated from each other as in the related art described above, when the remote control device and the gauge device are each attached to the attachment surface of the console, it is necessary to separately provide, on the attachment surface, a hole through which a cable for the remote control device connected to the remote control device passes and a hole through which a cable for the gauge device connected to the gauge device passes. In contrast, in the operation apparatus of the embodiment of the invention, the remote control device and the gauge device are integrated via the case, and thus, it is easy to bundle and integrate the cable for the remote control device connected to the remote control device and the cable for the gauge device connected to the gauge device. Therefore, when the case via which the remote control device and the gauge device are integrated is attached to the attachment surface of the console, it is sufficient to provide one hole through which an integrated cable (harness) passes in the attachment surface. Therefore, it is possible to reduce the number of holes provided in the attachment surface of the console through which the cables connected to the devices pass.
As described above, according to the operation apparatus of the embodiment of the invention, since the number of holes provided in the attachment surface of the console can be reduced, it is possible to reduce work quantity of the attachment work of attaching the remote control device and the gauge device to the attachment surface, and it is possible to improve the workability of the attachment work.
Hereinafter, some embodiments of an operation apparatus of the invention will be described with reference to the drawings. In each embodiment, when front (Fd), rear (Rd), left (Ld), right (Rd), upper (Ud), and lower (Dd) directions are described, the directions follow arrows drawn at a lower right portion of each drawing except for
(Configurations of Ship, Outboard Motor, and Operation Apparatus)
The hull 2 is provided with a console 4. In the present embodiment, the console 4 is disposed substantially at a center of a deck of the hull 2 in a front-rear direction and in a left-right direction. A steering wheel 9 serving as a steering device and the operation apparatus 10 are attached to an attachment surface 5 formed on an upper surface of an upper plate of the console 4. The steering wheel 9 is a device for performing a steering operation of the ship 1. The operation apparatus 10 is a device in which a remote control device 11 that performs a shift switching operation of the outboard motor 3 and an operation of increasing/decreasing a rotation speed of the engine of the outboard motor 3, a gauge device 31 that displays information on the outboard motor 3 and the like, and an emergency stop switch 51 that performs emergency stop on the engine of the outboard motor 3 are integrated.
The ship 1 according to the present embodiment is not provided with a seat for a ship operator to sit in front of the console 4. The ship operator stands in front of the console 4 and operates the ship. Note that the seat for the ship operator to sit on may be provided in front of the console 4, and the ship operator may sit on the seat to operate the ship.
(Operation Apparatus)
As shown in
(Remote Control Device)
The remote control device 11 is a device that performs the shift switching operation of the outboard motor 3 and the operation of increasing/decreasing the rotation speed of the engine of the outboard motor 3. As shown in
As shown in the lower left side of
The communicator 21 is attached to, for example, the angle sensor 20. As shown in
In
When the operation lever 16 is at the neutral position N, a detection signal indicating, for example, 0 degree is output from the angle sensor 20 to the communicator 21, and the detection signal is transmitted to the ECM of the outboard motor 3 via the communicator 21, the wireless communication device 71, and the signal transmission path. The ECM releases connection of gears between the engine and a propeller shaft of the outboard motor 3 based on the detection signal. As a result, rotation of a propeller is stopped in a state where the engine of the outboard motor 3 operates, and the ship 1 is stopped.
When the ship operator tilts the operation lever 16 to a far side (bow side) and the operation lever 16 is at the forward movement position F, a detection signal indicating, for example, 30 degrees is output from the angle sensor 20 to the communicator 21, and the detection signal is transmitted to the ECM of the outboard motor 3 via the communicator 21, the wireless communication device 71, and the signal transmission path. The ECM connects the gears between the engine and the propeller shaft of the outboard motor 3 based on the detection signal, so that the propeller of the outboard motor 3 rotates in a forward direction. As a result, the propeller rotates in the forward direction, and the ship 1 moves forward at a minimum speed.
When the ship operator tilts the operation lever 16 to a near side (stem side) and the operation lever 16 is at the reverse movement position R, a detection signal indicating, for example, −30 degrees is output from the angle sensor 20 to the communicator 21, and the detection signal is transmitted to the ECM of the outboard motor 3 via the communicator 21, the wireless communication device 71, and the signal transmission path. The ECM connects the gears between the engine and the propeller shaft of the outboard motor 3 based on the detection signal, so that the propeller of the outboard motor 3 rotates in a reverse direction. As a result, the propeller rotates in the reverse direction, and the ship 1 moves reversely at a minimum speed.
(Gauge Device)
The gauge device 31 is a device that displays information on the outboard motor 3, and the like. As shown in
As shown in
The ECM of the outboard motor 3 is configured to transmit information on the outboard motor 3 to the wireless communication device 71 via the signal transmission path provided in the ship 1. The wireless communication device 71 wirelessly transmits the information on the outboard motor 3 transmitted from the ECM to the communicator 36. The communicator 36 receives the information on the outboard motor 3 wirelessly transmitted from the wireless communication device 71, and outputs the received information on the outboard motor 3 to the controller 35. The controller 35 outputs the information on the outboard motor 3 output from the communicator 36 to the display device 32. The information on the outboard motor 3 is displayed on the display device 32 in this manner.
As shown on the lower side in
(Emergency Stop Switch)
The emergency stop switch 51 is a switch that performs emergency stop on the engine of the outboard motor 3. As shown on the right side in
A cord unit 61 is attached to the emergency stop switch 51. The cord unit 61 is an instrument that connects the emergency stop switch 51 and the ship operator. The cord unit 61 includes an extendable cord 62 formed in a coil spring shape, a lock plate 63 connected to one end portion of the cord 62, and a hook 64 connected to the other end portion of the cord 62. The lock plate 63 is hooked between the switch housing 52 and the movable portion 53 of the emergency stop switch 51. The hook 64 is hooked around, for example, the right wrist of the ship operator.
Since the lock plate 63 is hooked between the switch housing 52 and the movable portion 53 of the emergency stop switch 51, a state in which the movable portion 53 moves upward from the switch housing 52 against a biasing force of the biasing member is maintained. In this state, a contact of the emergency stop switch 51 is turned off, for example. On the other hand, when the ship operator is far away from the console 4 due to, for example, falling into water, the lock plate 63 is pulled by the cord 62 and is disengaged between the switch housing 52 and the movable portion 53. When the lock plate 63 is disengaged between the switch housing 52 and the movable portion 53, the movable portion 53 moves downward by the biasing force of the biasing member. As a result, the contact of the emergency stop switch 51 is turned on, for example.
As shown in
(Wireless Communication Device)
The wireless communication device 71 is a device that transmits signals or information between the ECM of the outboard motor 3 and the remote control device 11, the gauge device 31, or the emergency stop switch 51. As shown in
The harness 72 includes a signal transmission cable for transmitting the detection signal, the information on the outboard motor 3, and the emergency stop command signal. The harness 72 further includes power supply cables for supplying power from a battery provided in the ship 1 to each of the remote control device 11, the gauge device 31, the emergency stop switch 51, and the wireless communication device 71. The power supply cables are connected to each of the remote control device 11, the gauge device 31, the emergency stop switch 51, and the wireless communication device 71, so that power from the battery is supplied to the angle sensor 20 and the communicator 21 of the remote control device 11, the gauge device 31, the emergency stop switch 51, and the wireless communication device 71. In
(Case and Cap)
As shown in
As shown in
The remote control device 11 is attached to the left side attachment portion 87 of the case 81. Specifically, as shown in
In addition, the cap 93 is attached to the right side attachment portion 88 of the case 81. The cap 93 is formed in a cylindrical shape with a lid similarly to the holder 12 of the remote control device 11. A plurality of attachment bolt insertion holes 94 are formed in the cap 93 similarly to the holder 12. However, the shaft insertion hole 13 and the sensor fixing portion 15 formed in the holder 12 are not formed in the cap 93. The right side attachment portion 88 of the case 81 is provided with a plurality of attachment bolt holes similarly to the left side attachment portion 87. The cap 93 is fixed to the right side attachment portion 88 by inserting the attachment bolts 96 through the attachment bolt insertion holes 94 and fastening the attachment bolts 96 to the attachment bolt holes of the right side attachment portion 88.
Further, the gauge device 31 is attached to the stem side of the base portion 83 of the case 81 in the front-rear direction. Specifically, the gauge device 31 is fixed to an upper surface of the bottom plate 90, and the bottom plate 90 is fixed to the base portion 83, so that the gauge device 31 is accommodated inside a stem side portion of the base portion 83 in the front-rear direction. The gauge device 31 is disposed below the panel portion 85. The gauge device 31 is disposed such that the display screen of the display device 32 and the buttons 33 are located at a position corresponding to the window portion 86 of the panel portion 85. Therefore, the ship operator can visually recognize the display screen and operate the buttons 33 via the window portion 86.
The emergency stop switch 51 is attached to a left side of the gauge device 31 on the stem side of the base portion 83 of the case 81 in the front-rear direction. Specifically, in the panel portion 85, a switch attachment hole is formed on a left side of the window portion 86. The emergency stop switch 51 is fixed to the panel portion 85 by inserting an upper portion of the emergency stop switch 51 into the switch attachment hole from a lower side of the panel portion 85 and then fastening the fixing nut 54 to the upper portion of the emergency stop switch 51 from an upper side of the panel portion 85.
The wireless communication device 71 is accommodated in the accommodation portion 84 of the case 81. The wireless communication device 71 is fixed to the accommodation portion 84 or the bottom plate 90.
As shown in
A plurality of fixing bolt holes 92 through which the operation apparatus 10 is fixed to the attachment surface 5 of the console 4 are formed in the bottom plate 90. As shown in
As shown in
In the operation apparatus 10 according to the first embodiment of the invention having the above configuration, as shown in
Here,
As can be seen from a comparison between
Further, according to the operation apparatus 10 of the present embodiment, in addition to the remote control device 11 and the gauge device 31 being aggregated via the case 81 so as to be integrated, the remote control device 11 and the gauge device 31 are disposed adjacently to each other in the front-rear direction of the ship 1, and thus, an operation area for the ship operator operating the ship can be reduced, and a distance for the ship operator moving his/her arm to operate the ship can be reduced.
Specifically, in the related art, as shown in
In contrast, in the operation apparatus 10 according to the present embodiment, as shown in
When the distance D between the steering wheel 9 and the operation lever 16 of the remote control device 11 is reduced, a distance by which the arm moves to left or right when the ship operator alternately performs the steering operation by the steering wheel 9, the shift switching operation by the remote control device 11, and the like decreases, thereby improving operability. In addition, even when the ship operator repeats the movement of the arm in order to alternately perform the steering operation, the shift switching operation, and the like, the movement of the arm is reduced, and thus the cord 62 connecting the ship operator and the emergency stop switch 51 is less likely to be entangled.
In addition, according to the operation apparatus 10 of the present embodiment, by attaching the case 81 to the attachment surface 5 of the console 4, the remote control device 11, the gauge device 31, and the emergency stop switch 51 integrated via the case 81 can be provided on the attachment surface 5, and therefore, it is possible to improve workability of attaching the remote control device 11, the gauge device 31, and the emergency stop switch 51 to the console 4.
Specifically, in the related art, as shown in
In contrast, in the operation apparatus 10 according to the present embodiment, since the remote control device 11, the gauge device 31, and the emergency stop switch 51 are integrated via the case 81, as shown in
Further, in the operation apparatus 10 according to the present embodiment, the emergency stop switch 51 is disposed on the stem side of the remote control device 11 and on the left side of the gauge device 31. Accordingly, the emergency stop switch 51 can be brought close to the ship operator who operates the ship in front of the console 4, and the emergency stop switch 51 can be brought close to the steering wheel 9. By bringing the emergency stop switch 51 close to the ship operator and the steering wheel 9, even when the ship operator repeats movement of the right arm to operate the ship, a distance by which the cord 62 is moved is reduced, and a degree of extension and contraction of the cord 62 becomes small, and thus, the cord 62 is less likely to be entangled.
The operation apparatus 10 according to the present embodiment includes the wireless communication device 71, the detection signal is wirelessly transmitted from the communicator 21 of the remote control device 11 to the wireless communication device 71, the information on the outboard motor 3 is wirelessly transmitted from the wireless communication device 71 to the communicator 36 of the gauge device 31, and the emergency stop command signal is wirelessly transmitted from the communicator 55 of the emergency stop switch 51 to the wireless communication device 71. With this configuration, in the operation apparatus 10, a signal transmission cable that connects the angle sensor 20 of the remote control device 11 and the external connector 73, a signal transmission cable that connects the gauge device 31 and the external connector 73, and a signal transmission cable that connects the emergency stop switch 51 and the external connector 73 become unnecessary. Therefore, it is possible to prevent complication of wiring in the case 81, and it is possible to facilitate assembly of the operation apparatus 10.
(Replacement of Remote Control Device)
In the operation apparatus 10 according to the present embodiment, as shown in
Further, orientations of the remote control device 11 in the front-rear direction are reversed between the case where the remote control device 11 is attached to the left side attachment portion 87 and the case where the remote control device 11 is attached to the right side attachment portion 88. Therefore, it is necessary to reverse the forward movement position F, the reverse movement position R, the rotation speed operation range Cf, and the rotation speed operation range Cr in the case where the remote control device 11 is attached to the left side attachment portion 87 and in the case where the remote control device 11 is attached to the right side attachment portion 88. The remote control device 11 is provided with the setting selector switch 22 that reverses the setting of the forward movement position F, the reverse movement position R, the rotation speed operation range Cf, and the rotation speed operation range Cr between the case where the remote control device 11 is attached to the left side attachment portion 87 and the case where the remote control device 11 is attached to the right side attachment portion 88. The manufacturer or the user can switch the setting of the forward movement position F, the reverse movement position R, the rotation speed operation range Cf, and the rotation speed operation range Cr by operating the setting selector switch 22.
As described above, according to the operation apparatus 10 of the present embodiment, when the operation apparatus 10 is disposed on the right side of the steering wheel 9, the operation lever 16 of the remote control device 11 can be brought close to the steering wheel 9 by attaching the remote control device 11 to the left side portion of the case 81, and on the other hand, when the operation apparatus 10 is disposed on a left side of the steering wheel 9, the operation lever 16 of the remote control device 11 can be brought close to the steering wheel 9 by attaching the remote control device 11 to the right side portion of the case 81. Therefore, no matter the operation apparatus 10 is disposed on the right side or the left side of the steering wheel 9, the operability of the operation apparatus 10 can be improved.
According to the operation apparatus 101 of the second embodiment of the invention, the two remote control devices 11, the gauge device 31, and the emergency stop switch 51 are aggregated via the case 81 so as to be integrated, and thus, it is possible to reduce an attachment area of the two remote control devices 11, the gauge device 31, and the emergency stop switch 51 on the attachment surface 5 of the console 4. In addition, according to the operation apparatus 101 of the second embodiment of the invention, similarly to the operation apparatus 10 according to the first embodiment of the invention, it is possible to reduce the operation area for the ship operator operating the ship, and it is possible to improve workability of attaching the two remote control devices 11, the gauge device 31, and the emergency stop switch 51 to the console 4.
In each of the above embodiments, the case where the wireless communication device 71 that wirelessly communicates with each of the remote control device 11 (104), the gauge device 31, and the emergency stop switch 51 is provided is described as an example, but the wireless communication device 71 may not be provided. In that case, the operation apparatus 10 is provided with the signal transmission cable that connects the angle sensor 20 of the remote control device 11 (104) and the external connector 73, the signal transmission cable that connects the gauge device 31 and the external connector 73, and the signal transmission cable that connects the emergency stop switch 51 and the external connector 73. These signal transmission cables can be bundled together with a power supply cable to form one harness 72, and can be drawn out from the inside of the case 81 to the outside of the case 81 through the harness draw-out hole 91.
In each of the above embodiments, the emergency stop switch 51 is integrated with the remote control device 11 (104) and the gauge device 31 via the case 81, but the emergency stop switch 51 may be removed from the operation apparatus 10.
In addition, as the third and fourth embodiments according to the invention, the operation apparatus 102 including three remote control devices and the operation apparatus 105 including four remote control devices are described, but the operation apparatus according to the invention may include five or more remote control devices.
In each of the above embodiments, the case where the outboard motor is operated by the operation apparatus 10 is described as an example, but the invention is not limited thereto. The operation apparatus according to the invention can also be applied to an operation apparatus for operating an inboard-outboard motor or an inboard motor. The ship provided with the operation apparatus according to the invention is not limited to the small ship as shown in
The power source of the ship propulsion machine is not limited to the engine, and may be an electric motor. When the power source of the ship propulsion machine is an electric motor, the shift switching operation performed by the remote control device means an operation of switching a rotation direction of a rotor of the electric motor, and the information indicating the shift position in the gauge device means information indicating the rotation direction of the rotor of the electric motor.
In addition, each of the above embodiments describes, as an example, that in the remote control device 11 (104), the detection signal indicating the swing angle of the operation lever 16 with respect to the holder 12 is wirelessly transmitted from the communicator 21 to the wireless communication device 71 as the signal corresponding to the swing angle of the operation lever with respect to the holder, but instead, in response to the operation of the operation lever 16, the signal indicating the shift operation position N, F, or R, or the signal indicating an operation amount in the rotation speed operation range Cf or Cr may be wirelessly transmitted from the communicator 21 to the wireless communication device 71 as the signal corresponding to the swing angle of the operation lever with respect to the holder.
The invention can be modified as appropriate without departing from the scope or spirit of the invention which can be read from the claims and the entire description, and the operation apparatus accompanying such a change is also included in the technical concept of the invention.
