The radio transmitter 11 is operated to operate the radio transmitter 1
1 to accelerator lever 7 and forward / reverse switching clutch lever 8
When the command signal 10 for the command and the steering 9 is transmitted, the command signal 10 is received by the receiver 13 and the command signal 1 is transmitted.
0 is output to the control panel 16, where the signal 12 output from the receiver 13 is output.
, Control signals 14 and 15 are output to the lever power unit 17 and the steering power unit 18, and the accelerator lever 7 and the front and rear are controlled based on the control signals 14 and 15 output from the control panel 16 by the operation of the lever power unit 17. While the forward switching clutch lever 8 is driven, the steering 9 is driven based on the control signals 14 and 15 output from the control panel 16 by the operation of the steering power unit 18, and the boat can be steered wirelessly.

In the illustrated example, the accelerator switch 21 of the radio transmitter 11 is pressed (the radio transmitter 1 shown in FIGS. 3 and 4).
In the case of 1, the accelerator stick 29 is tilted upward.)
The command signal 10 is transmitted by the amount pressed, and the inner cable 39 of the wire cable 37 is pushed via the speed reducer 33 and the clutch 35 by the driving of the electric motor 31 of the lever power unit 17, whereby the accelerator lever 7 is moved. The engine is driven in the acceleration direction, and the engine speed is increased. However, when the switch 21 on the accelerator is kept pressed and the inner cable 39 is pushed to the upper limit, the limit switch 41 is activated and the detection signal 45 is sent to the control panel. 16
To the electric motor 3 based on the detection signal 45.
Since the drive of No. 1 is stopped, there is no fear that the inner cable 39 is pushed beyond the upper limit. On the other hand, the wireless transmitter 1
When the accelerator lower switch 22 is pressed (in the wireless transmitter 11 shown in FIGS. 3 and 4, the accelerator stick 29 is tilted downward), the command signal 10 is transmitted as much as it is pressed,
By driving the electric motor 31 of the lever power unit 17 in the opposite direction to that described above, the inner cable 39 of the wire cable 37 is pulled via the speed reducer 33 and the clutch 35, so that the accelerator lever 7 is driven in the deceleration direction and the engine When the number of revolutions is reduced, when the accelerator lower switch 22 is kept pressed and the inner cable 39 is pulled down to the lower limit, the limit switch 43 is activated and the detection signal 45 is output to the control panel 16 and the detection signal 45 is output. Since the drive of the electric motor 31 is stopped based on the signal 45, there is no fear that the inner cable 39 is pulled beyond the lower limit.

When the pre-clutch switch 23 of the radio transmitter 11 is pressed once (in the radio transmitter 11 of FIGS. 3 and 4, the clutch stick 30 is tilted forward), a command signal 10 is transmitted and the lever signal is transmitted. The reduction gear 34 and the clutch 36 are driven by the driving of the electric motor 32 of the power unit 17.
When the inner cable 40 of the wire cable 38 is pushed through the lever, the forward / reverse switching clutch lever 8 is switched to the forward side, and the clutch is switched to the forward side. However, the pre-clutch switch 23 is pushed many times. Even when the inner cable 40 is pushed to the upper limit,
When the limit switch 42 is actuated and the detection signal 45 is output to the control panel 16 and the drive of the electric motor 32 is stopped based on the detection signal 45, the inner cable 40 may be pushed beyond the upper limit. There is no. On the other hand, the switch 24 is pressed once after the clutch of the wireless transmitter 11 (FIG. 3).
And the wireless transmitter 11 shown in FIG.
Is tilted backward), the command signal 10 is transmitted,
By driving the electric motor 32 of the lever power unit 17, the inner cable 40 of the wire cable 38 is pulled through the speed reducer 34 and the clutch 36, the forward / reverse switching clutch lever 8 is switched to the reverse side, and the clutch is moved to the reverse side. However, even if the post-clutch switch 24 is pressed many times, if the inner cable 40 is pulled to the lower limit, the limit switch 42
Is activated and its detection signal 45 is output to the control panel 16,
Since the drive of the electric motor 32 is stopped based on the detection signal 45, there is no fear that the inner cable 40 is pulled beyond the lower limit. If the clutch neutral switch 25 is pressed once (if the clutch stick 30 is returned to the neutral position in the radio transmitter 11 of FIGS. 3 and 4), the forward / reverse switching clutch lever 8 is returned to the neutral position, and the clutch is neutralized. Returned to position.

Further, when the steering right switch 26 of the radio transmitter 11 is pressed, the command signal 10 is transmitted for the pressed amount.
When the solenoid valve 55 of the steering power unit 18 is switched, the port 52 of the rudder cylinder 51 is switched.
When the rudder cylinder 51 contracts and the rudder is turned rightward, the steering right switch 26 is kept pressed and the rudder cylinder 51 contracts to the limit position, the limit switch 60 is turned on. Activated and its detection signal 61
Is output to the control panel 16, and based on the detection signal 61,
The solenoid valve 55 is returned to the neutral position, the contraction of the rudder cylinder 51 is stopped, and there is no fear that the rudder cylinder 51 contracts beyond the limit position. On the other hand, when the steering left switch 27 of the radio transmitter 11 is pressed, the command signal 10 is transmitted by the amount of the pressing, and the solenoid valve 55 of the steering power unit 18 is switched in the opposite direction to the above. When the pressure oil 50 is supplied to 53 and the rudder cylinder 51 is extended, the rudder is turned to the left. However, when the steering left switch 27 is continuously pressed and the rudder cylinder 51 is extended to the limit position, the limit switch 59 is extended. Is activated to output a detection signal 61 to the control panel 16, and based on the detection signal 61, the solenoid valve 55 is returned to the neutral position, the extension of the rudder cylinder 51 is stopped, and the There is no worry about being stretched beyond the position. If the steering neutral switch 28 is pressed once, the rudder cylinder 51 returns to the neutral position, and the rudder returns to the neutral position.

As a result, when the crew moves on the ship,
The cable 3 does not get in the way and the work becomes easier.

The crew fixed the radio transmitter 11 shown in FIGS. 3 and 4 to the waist portion with a belt or the like.
