Returning to FIGS. 7 to 9, the sound deadening member 19 housed in the through hole 104 of the fixing member 10 has a cylindrical cam member 190 and a third attachment such as a compression coil spring arranged around the cam member 190. It is equipped with a force member 191. At the upper end of the through hole 104 of the fixing member 10 accommodating the sound deadening member 19, there is an eaves 105 protruding inward of the through hole 104. Since the upper end of the third urging member 191 is attached to the eaves 105 in the through hole 104 and the lower end is attached to the cam member 190, the cam member 190 is urged downward by the third urging member 191. Has been done.

The shape of the sound deadening member 19 will be further described. 11A and 11B are schematic perspective views showing an example of a cam member 190 of the sound deadening member 19 included in the key switch 1 described in the present application. FIG. 11A shows the cam member 190 from an obliquely upper viewpoint, and FIG. 11B shows the cam member 190 from an obliquely lower viewpoint. The cam member 190 of the sound deadening member 19 has a shape in which substantially cylindrical shapes are stacked in two stages, and the outer diameter of the lower stage is formed to be longer than the outer diameter of the upper stage. The lower end of the third urging member 191 is attached to the lower part of the sound deadening member 19.

An elastic portion 1900 made of soft rubber, a low-resilience resin, or the like is formed at the upper end of the cam member 190 so as to face the impact member 16. The elastic portion 1900 is a portion that is struck by the slamming member 16, but even if the elastic portion 1900 is struck by the slamming member 16, the impact of the slamming is absorbed, so that the generation of sound due to the slamming is suppressed. The lower end of the cam member 190 is a driven cam portion 1901 forming an annular shape. The driven cam portion 1901 is an end face cam formed in a circumferential shape, and four inclined surfaces inclined in the circumferential direction are formed at intervals of 90 degrees. The inclination of the driven cam portion 1901 of the cam member 190 substantially matches the inclination of the driving cam portion 133 of the switching lever 13, and the driving cam portion 133 of the switching lever 13 and the driven cam portion 1901 of the cam member 190 are engaged with each other. It fits. By engaging the driving cam portion 133 and the driven cam portion 1901, the driven cam portion 1901 of the cam member 190 slides on the inclined surface of the driving cam portion 133, based on the operation accepted by the switching lever 13. The swinging motion is transmitted from the driving cam section 133 to the cam member 190 via the driven cam section 1901, and the cam member 190 moves in the vertical direction. Engagement protrusions 1902 are projected at two locations at 180-degree intervals on the lower side surface of the cam member 190. The engaging projection 1902 projecting from the cam member 190 is adapted to engage with a guide groove (not shown) recessed in the vertical direction in the inner wall of the through hole 104 of the fixing member 10. When the engaging projection 1902 engages with the guide groove, the movement of the cam member 190 is guided by the guide groove and restricted in the vertical direction.

The names of the objects to be impacted are described as the rigid portion 103 and the elastic portion 1900, but these names have relative meanings of the respective portions, and the sound due to vibration is likely to be generated when the impact is applied. The one is called the rigid portion 103, and the one that absorbs the impact of the impact and is less likely to generate sound is called the elastic portion 1900. Therefore, the rigid portion 103 and the elastic portion 1900 do not absolutely limit the composition of the material, structure, shape, characteristics, etc. of these portions.

<Operation>
Next, the operation of the switch device described in the present application will be described. First, the operation at the time of the switching operation will be described. 12A and 12B are schematic cross-sectional views showing an example of a mechanism related to the switching operation of the key switch 1 described in the present application. 12A and 12b show a cross-sectional view of a part of the fixing member 10, a part of the switching lever 13, the cam member 190 of the muffling member 19, and the third urging member 191 as a mechanism related to the switching operation. There is.

FIG. 12A shows a state in which the driving cam portion 133 of the switching lever 13 and the driven cam portion 1901 of the cam member 190 are in mesh with each other without a gap. The driven cam portion 1901 meshes with the driving cam portion 133 with almost no gap, so that the cam member 190 is located on the lower side within the vertical movement range. In the state shown in FIG. 12A, the upper end of the elastic portion 1900 of the cam member 190 included in the sound deadening member 19 is located below (first direction) from the upper end of the rigid portion 103 in the fixing member 10. That is, since the rigid portion 103 is located above the elastic portion 1900, the impact member 16 strikes the opposed rigid portion 103 from above, and a sound is generated at the time of impact.

FIG. 12B shows a state in which the connecting operation member 2 receives a switching operation from the state shown in FIG. 12A, and the switching lever 13 swings with the operation of the connecting operation member 2. When the switching lever 13 swings in response to the switching operation, the driving cam portion 133, which is a circumferential end face cam formed on the switching lever 13, operates in the circumferential direction. When the driving cam portion 133 operates in the circumferential direction, the movement of the cam member 190 is restricted in the vertical direction, so that the driven cam portion 1901 of the cam member 190 moves upward while sliding on the driving cam portion 133. Therefore, when the switching lever 13 receives the switching operation, the upper end of the elastic portion 1900 of the cam member 190 included in the sound deadening member 19 moves relatively upward with respect to the upper end of the rigid portion 103 in the fixing member 10.

In FIG. 12B, when the switching lever 13 receives the switching operation, the relative position of the cam member 190 included in the muffling member 19 moves upward, and the upper end of the elastic portion 1900 of the cam member 190 included in the muffling member 19 is the fixing member 10. It shows a state of being located above (second direction) from the upper end of the rigid portion 103 inside. Since the elastic portion 1900 is located above the rigid portion 103, the impact member 16 strikes the opposing elastic portion 1900 from above, but the elastic portion 1900 absorbs the impact at the time of impact. Therefore, the sound generated at the time of impact is suppressed.

When the connecting operation member 2 receives the switching operation from the state shown in FIG. 12B and returns to the state shown in FIG. 12A, the driving cam portion 133 formed on the switching lever 13 operates in the circumferential direction, and the cam member 190 moves. , The third urging member 191 receives a downward urging and moves downward.

As described above, in the key switch 1 described in the present application, a simple switching operation of pulling out or pushing in the connecting operation member 2 protruding from the side portion of the keyboard KB is performed, so that a sound at the time of pressing the key switch 1 is performed. It is possible to switch between the occurrence and suppression of.

Next, the operation when the switch device described in the present application is pressed will be described. 13A to 13D are schematic cross-sectional views showing an example of a mechanism for pressing the key switch 1 described in the present application. 13A to 13D show a cross-sectional view of a movable member 11, an impact member 16, a second urging member 17, and an engaging member 18 as a mechanism related to a pressing operation.

FIG. 13A shows a state in which the key top 12 of the key switch 1 is not pressed. When the key switch 1 is not pressed, the movable member 11 is located at the top dead center. When the movable member 11 is located at the top dead center, the pressing portion 161 of the striking member 16 is located above the pressed portion 180 of the engaging member 18.

FIG. 13B shows a state in which the key top 12 is pressed and the movable member 11 is pressed downward from the state shown in FIG. 13A. When the movable member 11 is pressed downward, the movable member 11 moves downward, and the pressing portion 161 of the striking member 16 comes into contact with the pressed portion 180 of the engaging member 18 from above.

FIG. 13C shows a state in which the key top 12 is further pressed and the movable member 11 is pressed downward from the state shown in FIG. 13B. When the key top 12 is further pressed from the state shown in FIG. 13B, the pressing portion 161 of the striking member 16 engages with the pressed portion 180 of the engaging member 18 and moves downward from the second urging member 17. Against the force of. That is, the striking member 16 is supported by the engaging member 18 from below, so that the movable member 11 maintains its vertical position even though the movable member 11 moves downward, and the second urging member 17 Is compressed. By maintaining the position in the vertical direction, the striking member 16 moves upward relative to the movable member 11 and abuts on the bottom surface of the movable member 11 as shown in FIG. 13C.

FIG. 13D shows a state in which the key top 12 is further pressed from the state shown in FIG. 13C and the movable member 11 is moved downward. When the key top 12 is further pressed from the state shown in FIG. 13C, the movable member 11 moves downward, and the striking member 16 in contact with the bottom surface of the movable member 11 also moves downward together with the movable member 11. As the striking member 16 moves downward, the pressing portion 161 of the striking member 16 presses the pressed portion 180 of the engaging member 18, the pressed portion 180 is pressed, and the engaging member 18 bends outward. nothing. When the engaging member 18 bends, the pressed portion 180 of the engaging member 18 and the pressing portion 161 of the striking member 16 are disengaged, and the striking member 16 is urged by the second urging member 17. And move downward vigorously, hitting other members below. FIG. 13D shows a state in which the striking member 16 strikes another member below. At this time, the presence or absence of an impact sound is determined depending on which of the rigid portion 103 of the fixing member 10 and the elastic portion 1900 of the sound deadening member 19 is located above.

Although not shown in FIGS. 13A to 13D, when the transition from FIG. 13C to FIG. 13D, the contact pressing protrusion 112a projecting from the pressing side wall 112 of the movable member 11 is a movable piece 151b of the contact member 15. Is pressed to switch the contact / detachment state of the contact member 15. By switching the contact / detachment state of the contact member 15, an on signal indicating that the key switch 1 is pressed is output from the keyboard KB to the electronic device.

As described above, the key switch 1 according to the first embodiment described in the present application has an impact when switching the contact / detachment state of the contact member 15 by moving the movable member 11 in the pressing direction accompanying the pressing operation of the user. The striking member 16 strikes another member below. When the striking member 16 strikes the rigid portion 103 of the fixing member 10 as another member below, a sound accompanying the striking is generated, and the striking member 16 strikes the elastic portion 1900 of the muffling member 19. In that case, the generation of sound associated with the impact is suppressed. The switching between the rigid portion 103 and the elastic portion 1900, which are the targets of impact, is relative to the rigid portion 103 in the vertical direction due to the swing of the switching lever 13 accompanying the pulling out or pushing of the connecting operation member 2. It can be done by moving the target position. With such a configuration, the user can recognize the sound generated by the impact as a click sound. Further, in a situation where the generation of sound is not preferable, it is possible to suppress the generation of sound by a simple operation of putting in and taking out the connecting operation member 2. Moreover, in the switching operation using the connection operation member 2, it is possible to switch whether or not the sound is generated for the plurality of key switches 1 at once.

<Operation>
Next, the operation at the time of the switching operation of the switch device described in the present application will be described. First, the operation at the time of the switching operation will be described. 19 and 20 are schematic top views showing an example of the arrangement of the fixing member 10 and the sound deadening member 19 included in the key switch 1 described in the present application. FIG. 19 shows a state in which the muffling member 19 is located on the outside. In the state shown in FIG. 19, the rigid portion 103 of the fixing member 10 is exposed in a top view. In the state shown in FIG. 19, since the muffling member 19 is out of the moving range of the striking member 16, when the contact / disengagement state is switched by the pressing operation with respect to the movable member 11, the striking member 16 is attached to the second. It is urged by the force member 17 and strikes the opposing rigid portions 103 from above. When the striking member 16 strikes the rigid portion 103, a sound is generated at the time of striking.

FIG. 20 shows a state in which the connection operation member 2 receives a switching operation from the state shown in FIG. 19, and the sound deadening member 19 is pushed toward the fixing member 10 side and moves with the operation of the connection operation member 2. The muffling member 19 itself is urged in the direction opposite to the pushing direction by the third urging member 191. However, a locking portion such as a protrusion (not shown) formed on the muffling member 19 engages with the fixing member 10. However, it is held at the pushing position shown in FIG. As shown in FIG. 20, when the arrangement position of the sound deadening member 19 moves to the fixed member 10 side in response to the switching operation, the slide elastic portion 193 provided in the sound deadening member 19 moves above the rigid portion 103, and the rigid portion A part or all of the upper part of 103 is covered with the slide elastic portion 193. That is, the position of the slide elastic portion 193 included in the sound deadening member 19 is located between the rigid portion 103 and the striking member 16 within the moving range of the striking member 16. In the state shown in FIG. 20, since the muffling member 19 is located within the moving range of the striking member 16, the striking member 16 is urged to the second when the contact / detachment state is switched by the pressing operation with respect to the movable member 11. The member 17 is urged to hit the slide elastic portion 193 from above. By hitting the slide elastic portion 193 by the hitting member 16, the sound generated at the time of hitting is suppressed.

As described above, the key switch 1 according to the second embodiment described in the present application has an impact when switching the contact / detachment state of the contact member 15 by moving the movable member 11 in the pressing direction accompanying the pressing operation of the user. The striking member 16 strikes another member below. When the striking member 16 strikes the rigid portion 103 of the fixing member 10 as another member below, a sound accompanying the striking is generated, and the striking member 16 strikes the slide elastic portion 193 of the muffling member 19. If this is the case, the generation of sound associated with the impact is suppressed. Switching between the rigid portion 103 and the slide elastic portion 193, which are the targets of impact, is performed in the horizontal direction of the slide elastic portion 193 with respect to the rigid portion 103 due to the movement of the slide operation portion 192 accompanying the pushing or pulling out of the connecting operation member 2. It can be done by moving the relative position of. With such a configuration, the user can recognize the sound generated by the impact as a click sound. Further, in a situation where the generation of sound is not preferable, it is possible to suppress the generation of sound by a simple operation of pushing the connecting operation member 2. Moreover, in the switching operation using the connection operation member 2, it is possible to switch whether or not the sound is generated for the plurality of key switches 1 at once.

In the second embodiment, the individual key switch 1 is provided with a third urging member 191 for urging the muffling member 19, but the substrate 3 provided with the keyboard KB is provided with the urging member for the substrate. It may be provided and urged to the connecting operation member 2 by the urging member for the substrate.

<Third Embodiment>
In the third embodiment, in the second embodiment, the sound generation and suppression are switched depending on whether the impact member 16 strikes the rigid portion 103 of the fixing member 10 or the slide elastic portion 193 of the sound deadening member 19. Rather, the striking member 16 switches between generation and suppression of sound depending on whether or not the striking member 1E, which is the target of the striking, is impacted. In the following description, the configurations having the same functions as those of the first embodiment or the second embodiment are designated by the same reference numerals as those of the first embodiment and the second embodiment, and detailed description thereof will be omitted.

FIG. 21 is a schematic top view showing an example of the fixing member 10 included in the key switch 1 described in the present application. FIG. 22 is a schematic top view showing an example of the impacted member 1E included in the key switch 1 described in the present application. The fixing member 10 of the key switch 1 according to the third embodiment is formed in substantially the same shape as the fixing member 10 of the key switch 1 according to the second embodiment, but is directed upward as shown in the second embodiment. The rigid portion 103 is not formed. Therefore, the position where the rigid portion 103 is projected in the second embodiment is a low inner bottom surface in the fixing member 10. Since the inner bottom surface is lower than the lower limit of the moving range of the striking member 16 and is out of the moving range of the striking member 16, it is not subject to the striking of the striking member 16. The impacted member 1E has substantially the same shape as the sound deadening member 19 in the second embodiment, and includes a slide operation unit 1E0 similar to the slide operation unit 192 of the sound deadening member 19, but the slide elastic portion 193 has a slide elastic portion 193. A slide rigid portion 1E1 using a hard material is formed in the formed portion. By connecting the slide operation unit 1E0 of the impacted member 1E included in the key switch 1 according to the third embodiment to the connection operation member 2, a plurality of slide operation units 1E0 can be operated at the same time.

In the key switch 1 according to the third embodiment configured in this way, the operation is substantially the same as that of the second embodiment by the switching operation. Therefore, in the state where the hitting member 1E is located on the outside, the arrangement position of the slide rigid portion 1E1 included in the hitting member 1E is a position outside the moving range of the hitting member 16. When the contact / detachment state is switched by the pressing operation on the movable member 11, the striking member 16 is urged by the second urging member 17 and moves vigorously downward. However, when the arrangement position of the slide rigid portion 1E1 is out of the moving range of the impact member 16, since there is no impact target to be impacted by the impact member 16, no sound due to the impact is generated, and the sound is produced. The occurrence will be suppressed.

When the key switch 1 is subjected to a switching operation, the slide rigid portion 1E1 of the impacted member 1E is pushed toward the inside of the fixing member 10 and moves. That is, the position of the slide rigid portion 1E1 of the impacted member 1E is located within the moving range of the impacted member 16. When the contact / detachment state is switched by the pressing operation on the movable member 11, the striking member 16 is urged by the second urging member 17 and moves vigorously downward. Since the slide rigid portion 1E1 is arranged within the moving range of the impact member 16, the impact member 16 strikes the slide rigid portion 1E1 from above. When the striking member 16 strikes the slide rigid portion 1E1, a sound is generated at the time of striking.

As described above, in the key switch 1 according to the third embodiment, when the arrangement position of the slide rigid portion 1E1 of the impacted member 1E is out of the moving range of the impacted member 16, the impacted member 16 is impacted. Since there is no target for hitting, the generation of sound due to hitting is suppressed. When the arrangement position of the slide rigid portion 1E1 of the impacted member 1E is located within the moving range of the impact member 16 by the switching operation, the impact member 16 collides with the slide rigid portion 1E1 of the impacted member 1E. Because it hits, a sound is generated at the time of hitting.

The present invention is not limited to the embodiments described above, and can be implemented in various other embodiments. Therefore, the embodiments described above are merely exemplary in all respects and should not be construed in a limited way.

It can be set as appropriate within. When the upper end of the elastic portion 1900 is located at the same position as the upper end of the rigid portion 103 or above the rigid portion 103, the generation of sound is suppressed regardless of the position of the elastic portion 1900. When the upper end of the elastic portion 1900 is located below the lower end of the rigid portion 103, the vibration of the rigid portion 103 at the time of impact changes depending on the position of the elastic portion 1900, so that the impact sound changes. Therefore, it is possible to adjust the sound recognized as the click sound by the user.

Further, in the embodiment such as the first embodiment, the mode in which the switching levers 13 of the plurality of key switches 1 are simultaneously operated by the connecting operation member 2 is shown, but the connecting operation member 2 is removed and the individual key switches 1 are operated.
