Japanese Patent Laid-Open No. 10-254567

The conventional assembly structure of this type of joystick controller is generally a structure in which each part of the shaft, the rotation support mechanism, and the detection means is assembled one by one on the basis of the housing case. For this reason, the conventional joystick controller has a problem that it takes time to assemble and the production efficiency is not good.
The present invention has been made for the purpose of solving such problems.

In order to achieve the above object, the present invention

A pair of fixed shafts, the pair of fixed shafts being fixed to the housing case, and a first detecting means for detecting movement in the first direction is a first magnet provided on the fixed shaft. A first magnetic sensor provided on the hollow shaft, and a second detection means for detecting movement in the second direction includes a second magnet provided on the shaft and a second magnet provided on the hollow shaft. A magnetic sensor,
Together they form a unit separate from the housing case as collectively mechanism side unit shaft and the rotation supporting mechanism and the detecting means, respectively provided with grooves on two opposite sides of the housing case, to the two grooves The rotation support mechanism of the mechanism side unit is assembled so as to fit a pair of fixed shafts .

  With such a structure, the joystick controller of the present invention can be easily assembled and adjusted, and has a great effect on improving production efficiency.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an external appearance of a joystick controller according to an embodiment, and FIG. 2 is a longitudinal sectional side view showing the internal structure.
The joystick controller 1 of this example includes a housing case 2, a shaft 3 as an operating body, a rotation support mechanism 4 that supports the shaft 3 so as to be capable of tilting rotation with respect to the housing case 2, And first and second detection means 10 and 14 for detecting movements in the first and second operation directions, that is, the X-axis operation direction and the Y-axis operation direction, respectively, and outputting voltages corresponding thereto. The

  Here, the rotation support mechanism 4 is orthogonal to the rotation axis of the hollow shaft 6 at the center of the hollow shaft 6 as a shaft member rotatably supported by the housing case 2 via the fixed shafts 5a and 5b. The shaft 3 is configured so as to be rotatable about the support shaft 7 as a fulcrum, whereby the shaft 3 is rotated integrally with the hollow shaft 6 with respect to the housing case 2 to perform an operation in the X-axis direction. In addition, an operation in the Y-axis direction is performed by rotating the hollow shaft 6 with the support shaft 7 as a fulcrum. A knob 8 is attached to the tip of the shaft 3 to facilitate gripping the shaft 3. In this configuration, the shaft 3 is always returned to the neutral position by the force of the spring 9.

  The first detection means 10 detects the movement of the shaft 3 in the X-axis operation direction, and is arranged on the hollow shaft 6 side corresponding to the first magnet 11 arranged on the fixed shaft 5b side. And the first magnetic sensor 12. Here, the first magnetic sensor 12 is composed of an IC component that incorporates a Hall element that detects magnetism and outputs a voltage corresponding to its strength, and this is mounted on a substrate 13 fixed to the hollow shaft 6. It is.

  Then, by operating the shaft 3 in the X-axis direction, when the hollow shaft 6 is rotated integrally with the fixed shafts 5a and 5b as a fulcrum, the hollow shaft 6 becomes hollow with respect to the first magnet 11 on the fixed shaft 5b side. When the first magnetic sensor 12 on the 6 side rotates and the relative position of both changes, an electrical output corresponding to the operation amount of the shaft 3 in the X-axis direction can be obtained from the first magnetic sensor 12. is there.

  In the first detection means 10, the arrangement of the first magnet 11 and the first magnetic sensor 12 is reversed, that is, the first magnet 11 is placed on the hollow shaft 6 side, and the first magnetic sensor 12. Even when the configuration is such that is disposed on the fixed shaft 5b side, it is possible to obtain the same electrical output as described above.

  On the other hand, the second detection means 14 for detecting the movement of the shaft 3 in the Y-axis operation direction includes the second magnet 15 disposed on the shaft 3 side and the corresponding second magnet 15 disposed on the hollow shaft 6 side. 2 magnetic sensors 16. Here, the second magnet 15 is fixed to the shaft 3 so as to be arranged around the axis of the support shaft 7, and the second magnetic sensor 16 incorporates a Hall element similar to the first magnetic sensor 12. It is made of an IC component and is mounted on a substrate 13 fixed to the hollow shaft 6.

  Then, by operating the shaft 3 in the Y-axis direction, the second magnet 15 integrally rotates with the second magnetic sensor 16 on the hollow shaft 6 side, and the relative position of both changes. Thus, an electrical output corresponding to the operation amount of the shaft 3 in the Y-axis direction can be obtained from the second magnetic sensor 16. At that time, even when the shaft 3 is operated in the X-axis direction, the second detection means 14 moves integrally with the hollow shaft 6, so that it is independent of the operation of the shaft 3 in the X-axis direction. An output in the Y-axis operation direction can be obtained.

  In the second detection means 14, the arrangement of the second magnet 15 and the second magnetic sensor 16 is reversed, that is, the second magnet 15 is placed on the hollow shaft 6 side, and the second magnetic sensor 16. Even in the case where the shaft is arranged on the shaft 3 side, it is possible to obtain the same electrical output as described above.

  The joystick controller 1 of the present example configured as described above has a simple configuration for taking out an output corresponding to the movement of the shaft 3, and in particular, has a simple configuration for taking out an output in the Y-axis operation direction. Since the number of parts can be reduced and the part placement space can be saved, a compact joystick controller as a whole can be realized.

FIG. 3 is an exploded perspective view showing the assembly structure of the joystick controller of this example.
As shown here, in the joystick controller 1 of this example, the shaft 3, the rotation support mechanism 4, and the detection means 10 and 14 shown in FIG. 2 are combined, and the mechanism side unit 18 separated from the housing case 2. As a unit.

  On the other hand, the housing case 2 is provided with concave grooves 19a and 19b that are opened upward on the opposite side surface portions 2a and 2b, and the rotation support mechanism 4 of the mechanism side unit 18 is fitted therein. The structure is assembled.

  As an assembling procedure, first, the fixed shafts 5a and 5b are inserted into both ends of the hollow shaft 6 of the mechanism side unit 18 so as to be temporarily assembled. The mechanism-side unit 18 is assembled to the housing case 2 so as to be fitted, and then the fixed shafts 5 a and 5 b are fixed to the housing case 2 with screws 20.

  As described above, the joystick controller of this example can be manufactured as an independent unit 18 on the mechanism unit side, so that the assembly work efficiency can be improved. Also, the fixed shafts 5a and 5b can be assembled with the housing case 2. Since positioning can be performed along the concave grooves 19a and 19b in a temporarily assembled state inserted into the hollow shaft 6, assembly and adjustment are facilitated, which has a great effect on improving production efficiency.

  As mentioned above, although the Example of this invention was described, it cannot be overemphasized that this invention can take other various embodiment, without being limited to the structure of this Example.

It is a perspective view which shows the external appearance of the joystick controller of an Example. It is a vertical side view showing an internal structure. It is an exploded perspective view showing an assembly structure.
