TECHNICAL FIELD [0001] The present invention relates to an operating member that is attached to a rotating member that is rotatably provided around an axis, and that is operated when rotating the rotating member, an attaching method thereof, a switch device, and an electronic apparatus.

Background art

Conventionally, for example, a switch device operated by a user when operating an electronic device is known. As such a switch device, a configuration shown in FIGS. 1 and 2 that is rotated by a user is known. A switch device 900 shown in FIGS. 1 and 2 includes a switch base member 910 and an operation member 920.

[0003] The switch base member 910 includes a shaft member 911 having a substantially round bar shape, a bearing member (not shown), and a rotation signal output board. The shaft-shaped member 911 has a D-cut portion 911 A formed in a columnar shape with a substantially D-shaped cross section (hereinafter referred to as an axial orthogonal cross-section) perpendicular to the shaft, and one axial end side of the D-cut portion 91 1A. And a shaft base portion 911B formed in a columnar shape with a cross section orthogonal to the axis. The outer peripheral surface of the D-cut portion 911A includes an arc-shaped arc surface portion 911A1 and a planar D-cut plane portion 911A2 that connects both ends of the arc-shaped surface portion 911A1 in the arc direction. The bearing member includes a hollow portion in which one end side of the shaft base portion 911B is inserted so as to be rotatable about the shaft. The rotation signal output board is attached to the bearing member, detects the rotation state of the shaft-like member 911, and outputs a rotation state signal corresponding to this rotation state.

[0004] The operation member 920 includes a substantially cylindrical operation main body 921 whose one surface is closed. On one surface of the operation main body 921, a fitting portion 922 to which the D cut portion 911A of the switch base member 910 is fitted is provided in a state of protruding in a substantially cylindrical shape in the direction of the other surface. The fitting portion 922 includes a first arc plate portion 922A formed in a substantially arc plate shape, and a second arc plate portion 922B arranged in a state of facing the first arc plate portion 922A. And.

[0005] On the inner peripheral surface of the first arc plate portion 922A, the D-cut flat portion 911A2 of the D-cut portion 911A A fitting flat surface portion 922A1 corresponding to the shape is provided. These first and second arcuate plate portions 922A and 922B can be elastically deformed in the direction approaching each other, and the hollow portion 922C formed by the opposing surfaces is substantially the same as the outer shape of the D-cut portion 911A. It is provided in a shape. In addition, a substantially cylindrical spring member 923 that urges the first and second arc plate portions 922A and 922B in a direction approaching each other in a state of covering the outer peripheral surface is attached to the fitting portion 922. .

[0006] Then, the operating member 920 is attached to the shaft-like member 911 by fitting the D-cut portion 911A into the hollow portion 922C of the fitting portion 922. The fitting of the hollow portion 922C and the D-cut portion 911A prevents the operation member 920 from rotating with respect to the shaft-like member 911. Further, by tightening the D-force portion 911A by the biasing force of the spring member 923 via the first and second arc plate portions 922A and 922B, the axial member 911 of the operation member 920 is moved in the axial direction. That is, a configuration is employed in which the operation member 920 is prevented from being pulled out.

Disclosure of the invention

Problems to be solved by the invention

[0007] However, in the configuration like the switch device 900 as described above, the operation member 920 is prevented from being pulled out by the biasing force of the spring member 923, and therefore, the switch device 900 is affected by the performance variation of the spring member 923. An example of the problem is that the difficulty of pulling out each operation member 920 may vary. Also, if the biasing force of the spring member 923 is increased to make it difficult to pull out the operation member 920, the force required to fit the D-cut portion 911A to the fitting portion 922 increases, and the operation member 920 is pivoted. As an example, there is a problem that workability at the time of attaching to the member 911 may be lowered.

[Mounting method of operation member]

Next, a method for attaching the operation member 550 will be described with reference to the drawings. FIG. 6 is a perspective view showing a state in which the second member is fitted to the shaft-like member. FIG. 7 is a perspective view showing a state where the second member is rotated by 90 °. FIG. 8 is a perspective view showing a state in which the first member is attached to the second member.

First, the D cut portion 521 of the shaft-like member 520 is fitted into the D hole portion 574 of the second member 570, and the second member 570 is inserted into the D hole portion 574 as shown in FIG. Move to position where 522 is inserted. Then, as shown in FIG. 7, the second member 570 is rotated by 90 °. At this time, the straight hole portion 574A of the D hole portion 574 and the D cut plane portion 521B of the D cut portion 521 are orthogonal to each other, and the peripheral portion of the D hole portion 574 is locked to the D cut portion 521. Further, the hook-like protrusion engaging hole 575 is in a state in which the imaginary line connecting them is orthogonal to the D-cut flat surface portion 521B of the D-cut portion 521. Further, the first member 560 is moved in the direction approaching the second member 570, and the inclined portion 563B1 of the locking portion 563B of the hook-like projection 563 is moved to the peripheral portion of the hook-like projection engaging hole 575. Make contact. Thereafter, when the first member 560 is moved, the protrusion 563A of the hook-like protrusion 563 is inertially squeezed toward the radial center of the second member 570, and the locking part 563B is moved to the second member 570. Move toward the radial center. Then, when the first member 560 is further moved, the locking portion 563B passes through the hook-like protrusion engaging hole 575, and the protrusion 563A is inserted into the hook-like protrusion engaging hole 575. The protrusion 563A is restored. As a result, as shown in FIG. 8, the locking portion 563B moves outward in the radial direction of the second member 570 and is locked to the peripheral edge portion of the hook-like protrusion engaging hole 575. [0033] Since the peripheral edge portion of the D hole 574 is locked by the D cut portion 521, the second member 570 is prevented from being pulled out from the shaft-like member 520. Further, the fitting of the D-cut portion 521 to the fitting portion 565 prevents the rotation of the first member 560 relative to the shaft-like member 520. Further, the first member 560 is fixed to the second member 570 by the locking portion 563 B being locked to the peripheral edge portion of the hook-like protrusion engaging hole 575. For these reasons, the operating member 550 is attached in a state in which the shaft member 520 is prevented from being pulled out and rotated.

[0034] [Effects of radio device]

As described above, in the above embodiment, the operation member 550 includes the first member 560 provided on the axial end of the shaft-shaped member 520 and the D hole 574 through which the shaft-shaped member 520 is inserted.

In addition, a rotation preventing portion that prevents the rotation of the first member 560 relative to the shaft-shaped member 520 and a fixing portion that fixes the first member 560 and the second member 570 are provided. For this reason, the difficulty of pulling out the operation member 550 is determined by the locking state of the shaft-shaped member 520 and the second member 570, and compared with the conventional switch device 900 determined by the biasing force of the spring member 923. Thus, variations in the difficulty of pulling out each first switch device 500 can be suppressed. Further, in order to make it difficult to pull out the operation member 550, the force required to provide the second member 570 and the first member 560 on the shaft-shaped member 520, and the first member 560 to the second member 570 are provided. Compared with the conventional switch device 900 in which it is not necessary to increase the fixing force, workability when the operation member 550 is attached to the shaft-like member 520 can be improved. Therefore, the operation member 550 can be favorably attached to the shaft-like member 520. Further, since the operation member 550 is composed of the first and second members 560 and 570, for example, the design can be improved by forming them with different colors.

Further, the shaft-shaped member 520 is provided with a D-cut portion 521 and an intermediate portion 522, and the D hole portion 574 is formed in a shape substantially equal to the axial orthogonal cross section of the D-cut portion 521. Therefore, the D cut portion 521 is fitted into the D hole portion 574, the second member 570 is moved to a position where the intermediate portion 522 is inserted into the D hole portion 574, and the second member 570 is moved to the D hole. The second member 570 can be prevented from being pulled out by rotating the peripheral portion of the portion 574 so as to be engaged with the D-cut portion 521. Therefore, the second member 570 can be prevented from being pulled out by simply inserting the second member 570 through the shaft-like member 520 and rotating, and the workability can be further improved.

In addition, a D-cut portion 521 is provided on the shaft-shaped member 520, and a fitting portion 565 on which the D-cut portion 521 is fitted is provided on the first member 560. For this reason, with a simple configuration in which the D-cut portion 521 is fitted to the fitting portion 565, the rotation of the first member 560 relative to the shaft-like member 520 can be prevented, and workability can be further improved.

[0037] The first member 560 is provided with a hook-shaped protrusion 563, and the second member 570 is provided with a hook-shaped protrusion engaging hole 575. Therefore, the first member 560 can be fixed to the second member 570 with a simple configuration in which the hook-shaped protrusion 563 is simply engaged with the hook-shaped protrusion engaging hole 575, and the workability is further improved. It can be improved.

In addition, the hook-shaped protrusion 563 is provided with a locking portion 563 B that is locked to the peripheral edge of the hook-shaped protrusion engaging hole 575. Therefore, the first member 560 can be firmly fixed to the second member 570 by locking the locking portion 563B to the peripheral edge portion of the hook-shaped protrusion engaging hole 575.

Furthermore, a plurality of hook-like protrusions 563 are provided around the fitting part 565, and a plurality of hook-like protrusion engaging holes 575 are provided around the D hole part 574. For this reason, the first member 560 and the second member 570 can be more firmly fixed.

In addition, the operation member 550 that can be satisfactorily attached to the shaft-like member 520 is applied to the first and second switch devices 500 and 600 of the radio device 100. For this reason, it is possible to suppress variations in the difficulty of pulling out the operating member 550 of the first and second switch devices 500 and 600 of the radio device 100, and to reduce the variation of the first and second switch devices 500 and 600 or the radio device 100. Workability when manufacturing the device 100 can be improved.
