Along with being there,
A bevel gear 24b attached to the tip of the drive shaft 24a of the other rotation drive motor 24 meshes with a bevel gear 28a provided at the upper end of a rotation tube 28 that rotates the propulsion device 26 attached to the port side.

Note that when each forward/reverse handle 6.7 is in the neutral position, the propulsion device 25, 26 will not rotate unless the swing handle 1 is rotated from the neutral position in the 2θ dice direction or in the counterclockwise direction. 1 in a clockwise or counterclockwise direction by 2θ degrees, the propulsion devices 25, 26 are configured to rotate to positions that cause the ship to traverse to the right or left, respectively.

Furthermore, a pair of prime mover control knobs 31, 32 are provided on the upper part of each of the forward and backward movement handles 6.7 so as to be rotatable in the circumferential direction.

47a and mesh with each other. By rotating each prime mover control knob 31, 32, rotation control, clutch control, variable pitch control, etc. of each prime mover 38, 39 are performed.

Next, the operation of the ship control device according to the present invention configured as described above will be explained.

First, when the steering device of this vessel is in the neutral position, when the prime mover control knob 31.32 is rotated by the same angle around its axis, the control transmitter 33. 34 respectively operate and a command signal is output. This signal causes the -C prime mover 38,39 to pass through the prime mover control circuit 36,37 and the prime mover control governor 40,41
rotates respectively. This rotation is caused by the drive shaft 38a and the bevel gear 38b.

・12& and vertical axis 42. It is transmitted to the propulsion shaft 46 via the bevel gears 42b and 46a, and rotates the starboard propeller 44, as well as the ffl driving shaft 39a and the bevel gear 39b.

43a and vertical axis 43. It is transmitted to the propulsion shaft 47 via the bevel gears 43b and 47a and rotates the port propeller 45, but as shown in FIG. In this position, the ship is at a standstill.Next, in this state, if the pair of forward/reverse handles 6,7 are grasped by their prime mover control knobs 31,32 with one hand and tilted forward at the same angle,
Via the second transmission means 14.14, the forward and backward movement transmitter 12
13 is activated and a command signal is issued. This signal activates the swing motor (9) - drive pump 19.20 via the swing control circuit 15.16 and the swing pump control device 17.18, respectively.

Then, the swing drive motors 23, 24 rotate via the hydraulic pipes 21, 22, respectively. This rotation is caused by the drive shaft 23a + 248 + bevel gear (23b).

27a), (24b, 28a) and the rotating cylinder 27°2
8, the starboard propulsion device 25 rotates clockwise, the port propulsion device 26 rotates counterclockwise, and the propulsion device 25 is moved to the command position of the forward/reverse handle 6.
．． When the numbers 26 and 26 match, signals are output from the turning tracking devices 29 and 30 to the turning control circuits 15 and 16, and the rotation of the propulsion devices 25 and 260 is stopped. Therefore,
The more the forward/reverse handle 6.7 is tilted forward, the more the starboard propulsion device 25 rotates clockwise in FIG. 6, and the more the port propulsion device 26 rotates counterclockwise. , the ship increases speed and moves forward. Then, when the forward/reverse handle 6.7 is tilted most forward, the propulsion device 25.26 rotates 2θ from the neutral position, so that the port and starboard propulsion shafts 46.47 are in parallel with each other. None, move forward at the fastest (10) speed.

Furthermore, when the turning handle 1 is turned counterclockwise in this state, the turning transmitter 3 is transmitted via the first transmission means 5.5.
．． 4 is activated and a command signal is issued. This signal causes the swing pump control devices 17, 18 to operate via the swing control circuits 15 and 16, and the swing motor drive pumps 19, 20 to operate, respectively. Then, the swing drive motors 23 and 24 are rotated via the hydraulic pipes 21 and 22, respectively. This rotation is caused by the drive shaft 23 & + 2
4a, bevel gears (23b, 27a), (24b, 28a)
As a result, both the rotating tubes 27, 28 are rotated by the same amount clockwise, so the port and starboard propulsion devices 25, 26 are rotated clockwise with their respective propulsion shafts 46, 47 kept parallel to each other. Then, the turning handle 1 and the forward/backward movement handle 6
．． When the propulsion device 25, 26 matches the command position of 7, the turning tracking device 29.30 outputs a signal and the propulsion device 25
．． 260 rotation, so the ship loses its propulsion system 25.
26 in the state shown in the figure, then move forward and turn left.

(11) Similarly, as shown in FIG. 7, when the turning handle 1 is turned clockwise while the ship is moving forward, the propulsion device 2
5.26 rotates counterclockwise and the ship turns to the right.

Furthermore, as shown in FIG. 2, a forward and backward movement handle 6.
7 is pulled backward by the same angle from the neutral position, the starboard propulsion device 25 rotates counterclockwise and the port propulsion device 26 rotates clockwise, so that the boat moves astern. In this state, when the turning handle 1 is rotated counterclockwise as shown in Fig. 1θ, the propulsion device 25, 26 rotates counterclockwise while its propulsion shafts 46, 47 remain parallel to each other. , the ship moves backwards and turns left. Also, as shown in Figure 1/(a),
When the turning handle 1 is rotated counterclockwise by θ° with the forward/reverse handle 6.7 in the neutral position, the starboard propulsion device 25 will move clockwise and the port propulsion device 26 will move counterclockwise. After rotating by the same amount, the ship enters the state shown in Figure 1 (bl), so the ship skids to the left as shown in Figure 1 (fc). Although typical aspects of ship maneuvering have been described above, the ship can be freely operated by operating the turning handle 1 and the forward and backward movement handles 6 and 7.

In addition, the forward and backward movement handles 6.7 are each independent,
Starboard and port propulsion devices 25.26t - It is also possible to rotate each separately, in addition to the above maneuvering,
Capable of a wide range of maneuvers. A summary of these aspects of ship maneuvering is shown in Figure 72 (A) ←) (C).

As explained above, the present invention has a swing handle that is rotatably provided in a plane substantially parallel to the surface of the mounting case, and a forward and backward movement handle that is provided in the center of the swing handle so that it can be raised and folded in the front and rear directions. In addition, since the motor control knob is provided on the forward/reverse handle so that it can rotate freely in the circumferential direction, each operation part is centralized in one place, and a human operator can easily propel the vehicle with one hand. It has the excellent effect that the device and the prime mover for the propulsion device can be controlled simultaneously, and even an unskilled person can easily operate the ship. Further, there are other advantages such as the device can be manufactured in a small size and the installation space can be small.
