Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

<< First Embodiment >>

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings of FIGS. 1 to 14.

FI G.1 to FI G.3 show the structure and operation of the operation switch according to the first embodiment. FIG. 4 and FIG. 5 are diagrams showing an example of a circuit configuration of this operation switch, and FIG. 6 is a diagram showing a control flow by this operation switch. FIG. 7 to FIG. 10 are diagrams showing processing examples of a driver program for detecting an operation to this operation switch, and FIG. 11 and FIG. 12 are strokes of this operation switch. It is a graph which measured the operation correct answer rate (non-erroneous operation probability) when the load was changed, and FIG. 13 and FIG. 14 are configuration diagrams of a modification of the operation switch.

Fig. 1 shows the structure (standby state) of this operation switch. This operation switch is set on the substrate 1 to be operated, and detects a two-stroke pressing operation. Two-stroke means that a two-stage state is detected by one press operation. Therefore, one press operation generates the first stroke and the subsequent second stroke.

Here, the substrate 1 is, for example, an outer wall of a housing of a mobile terminal. However, the substrate 1 may be a substrate constituting an operation switch independent of such a housing. In this case, for example, the substrate 1 may be fixed to a housing or a substrate of a portable terminal or the like by a method such as screwing, fitting, or bonding.

This operation switch includes contact switches 5A and 5B embedded in the substrate 1, dome reversing springs 2A and 2B covering these contact switches 5A and 5B, and dome reversing springs 2A and 2B. It has a bridge part 3 bridging between 2B and a button part 4A and 4B provided on the bridge part 3.

Contact switches 5A and 5B each have two contacts that make contact when pressed. The dome reversing springs 2A and 2B are so-called disc springs, and when pressed with a predetermined load, the dome portion collapses. The combination of the contact switch 5A (or 5B) and the dome reversing spring 2A (or 2B) constitutes a switch that opens and closes the contact depending on the presence or absence of a predetermined load.

The bridge component 3 has a function of distributing the load received by itself to the two dome reversing springs 2A and 2B. The buttons 4A and 4B clearly indicate the position where the user presses the operation switch and have the function of receiving the load due to the user's pressing operation. provide. This load is transmitted to the bridge part 3 as it is.

For example, in Fig. 1, the button part 4A is installed on the bridge part 3 at a position where the line connecting the center of the dome inversion spring 2A and the center of the dome inversion spring 2B is internally divided by a: b. Have been. For this reason, the load on the button portion 4A is distributed to the dome reversing springs 2A and 2B at a ratio of b: a.

FIGS. 2 and 3 show the state of the operation switch when button part 4A is pressed. Hereinafter, the operation principle of the operation switch will be described assuming that a <b.

When the operator presses the button portion 4A on the bridge part 3, the two dome reversing springs 2A and 2B are pressed unevenly as described above. In other words, a force b / a times that of the dome reversing spring 2B acts on the dome reversing spring 2A near the pressed button portion 4A.

When this force exceeds a predetermined value, the dome reversing spring 2A reverses. As a result, the switching of the switch of the first stroke is completed, and the contact switch 5A is turned on (FIG. 2).

When the operator further intensifies the load on the button section 4A, the operator places the load on the inverted dome reversing spring 2A (the position shown in (C) of FIG. 2) as a fulcrum. A counterclockwise rotating force is applied to the dome reversing spring 2B.

When the load exceeds a predetermined value, the dome reversing spring 2B reverses. As a result, the switching of the second stroke switch is completed, and the contact switch 5B is turned on (FIG. 3).

As described above, in the operation switches shown in FIGS. 1 to 3, the installation position of the button part 4 A (the position that internally divides the line connecting the center of the dome reversing spring 2 A and the center of 2 B) As a result, an unbalanced load is applied to the dome reversing springs 2A and 2B. Therefore, contact switches 2A and 2B are turned on in two strokes. This is the same when the button 2B is pressed.

In the operation switch of FIG. 1 (and FIG. 2 and FIG. 3), the pressing members 3 A and 3 B are attached to the part 3 to press the dome reversing springs 2 A and 2 B. Is provided. The dome reversing spring is provided by the pressing members 3A and 3B. The vicinity of the center of 2A and 2B can be reliably pressed. However, even without such pressing members 3A and 3B, the operation switch of the present embodiment can function.

Fig. 4 and Fig. 5 show examples of the circuit configuration of this operation switch. FI G. 4 is composed of two separate contact switches, 5 A (its contacts are called contacts A) and 5 B (its contacts are called contacts B) shown in FI G. 1 to FI G. 3 2 This is an example of configuring a circuit by applying it to a system circuit.

FIG.5 is a modification of FIG.4, and the circuit is configured by sharing the ground line 1 (GND) between the two circuits.

Control flow>

FIG. 6 shows a control flow chart when controlling the control target using the operation switch of the present embodiment. Now, assume that the operation switch is connected to a certain system.

For example, if the operator presses button 4A in the standby state (contacts A and B are both open), contact A is first turned on in the first stroke (arrow A-ON). As a result, the system to which the operation switch is connected detects the first stroke of the button 4A by the operator and executes the operation A1. This first stroke is called stroke A1.

Then, when the contact A is turned on and the operator releases the button 4A in this state, the state returns to the standby state (arrow A—OFF). On the other hand, if the operator further increases the load on button 4A while contact A is on, contact B will be turned on in addition to contact A (arrow B—ON). As a result, the system to which the operation switch is connected detects the second stroke of the button 4A by the operator and executes the operation A2. This second stroke is called stroke A2.

Then, when the operator weakens the pressing of the button 4A while the contacts A and B are on, the contact B is first opened. This causes the system to return only contact A to the ON state (arrow B—OFF). Further, when the operator weakens the pressing of the button 4A, the contact A is subsequently opened. This returns the system to the standby state (arrow A -OFF).

The state change of the operation switch by pressing the button 4A has been described above. The same applies to the change in state caused by pressing button 4B and the operation of the system to which the operation switch is connected. Also, the first and second strokes for button 4B are referred to as stroke B1 and stroke B2.

As described above, in this operation switch, the first stroke is always detected first, and then the second stroke is detected. Therefore, when a system is configured using this operation switch, the processing by the first stroke (A1 or B1 in FIG. 6) is replaced by the processing by the second stroke (A2 or B2 in FIG. 6). It is necessary to assign functions that can be executed earlier without causing problems.

For example, when this operation switch is used as a scroll key of a portable terminal, a line scroll may be assigned as a first stroke and a page scroll may be assigned as a second stroke.

For the first stroke, only the stroke detection and internal state transition (transition from standby state to contact A on) are made, and the contact is opened by releasing button 4 A etc. A—The transition from ON to the standby state (A—OF F transition) may cause the system to execute its operation.

FIG. 7 to FIG. 10 show processing of a driver program for detecting an operation on the operation switch of the present embodiment. This driver program detects changes (HI and LO) in the signal level input to the CPU port through this operation switch.

This driver program first initializes state variables A and B to 0 (S1). This state corresponds to the FIG.6 standby state. Next, the driver program waits for input (S2).

When there is an input, the driver program determines whether or not the contact switch 5A (contact A) is an ON input (S3). When the contact switch 5A is ON, the driver program determines whether or not the state variable A is 0 (S4). When the state variable A is not 0, the driver program returns control to S2. Already contact points This is because the ON input of the switch A is recorded in the state variable.

On the other hand, when the state variable A is 0 in the determination in S4, the driver program further determines whether or not the state variable B is 0 (S5). If the state variable B is 0, the driver program sets the state variable A to 1 (S6). Then, the driver program reports to the system OS (not shown) that the stroke A1 has been detected (S7). This is because the contact switch 5A was short-circuited in the first stroke. Thereafter, the driver program returns control to S2.

When the state variable B is not 0 in the judgment of S5, the driver program sets the state variable A to 1 (S8). Then, the driver program reports to the system OS (not shown) that the stroke B2 has been detected (S9). This is because the contact switch 5A was short-circuited in the second stroke. Then, the program returns control to S2.

In the determination of S3 in FI G.7, when the contact switch 5A (contact A) is not the input of ON, the driver program determines whether the contact switch 5A (contact A) is the input of OFF (FI G. 8 S10).

If the contact switch 5A is off, the driver program determines whether the status variable A is 0 (S11). When the state variable A is 0, the driver program returns the control to S2. This is because the state of the contact switch 5A has already been turned off.

On the other hand, if the status variable A is not 0 in the determination of S11, the driver program determines whether or not the status variable B is 0 (S12). When the state variable B is 0, the program sets the state variable A to 0 (S13). Then, the driver program reports the release of the stroke A1 to the OS (S14). This is because the contact switch 5A was opened in the first stroke. Thereafter, the driver program returns control to S2.

If the state variable B is not 0 in the judgment of S12, the driver program sets the state variable A to 0 (S15). Then, the driver program reports the release of the stroke B2 to the OS (S16). This is because the contact switch 5A was opened in the second stroke. Thereafter, the driver program returns control to S2. If contact switch 5A (contact A) is not an off input in the determination of S10 in FI G. 8, the driver program determines whether contact switch 5B (contact B) is an on input. (FI G. 9 S 20).

When the contact switch 5B is ON, the driver program determines whether or not the state variable B is 0 (S21). When the state variable B is not 0, the driver program returns control to S2. This is because the ON input of the contact switch B has already been recorded in the state variable.

On the other hand, when the state variable B is 0 in the determination of S21, the driver program further determines whether or not the state variable A is 0 (S22). If the state variable A is 0, the driver program sets the state variable B to 1 (S23). Then, the driver program reports to the OS of the system that the stroke B1 has been detected (S24). This is because the contact switch 5B was short-circuited in the first stroke. Thereafter, the driver program returns control to S2.

If the determination in S22 indicates that the status variable A is not 0, the driver program sets the status variable B to 1 (S25). Then, the driver program reports to the OS of the system that the stroke A2 has been detected (S26). This is because the contact switch 5B was short-circuited in the second stroke. Thereafter, the driver program returns control to S2.

When the contact switch 5B (contact B) is not an on input in the determination of S20 in FI G. 9, the driver program determines whether the contact switch 5B is an off input (see FI G. 10 S 30).

If the contact switch 5B is off, the driver program determines whether the state variable B is 0 (S31). When the state variable B is 0, the driver program returns control to S2. This is because the state of the contact switch B has already been turned off.

On the other hand, if the status variable B is not 0 in the determination of S31, the driver program determines whether the status variable A is 0 (S32). When the state variable A is 0, the driver program sets the state variable B to 0 (S33). Then, the driver program reports the release of the stroke B1 to the OS (S34). In the first stroke This is because the contact switch 5B has been opened. Thereafter, the driver program returns control to S2.

If the state variable A is not 0 in the judgment of S32, the driver program sets the state variable B to 0 (S35). Then, the driver program reports the release of the stroke A2 to the OS (S14). This is because the contact switch 5B was opened in the second stroke. Thereafter, the driver program returns control to S2.

Fig. 11 and Fig. 12 show graphs of the measurement results obtained by measuring the correct operation rate of the operator in the system using this operation switch. Here, the operation correct answer rate means a probability of not performing an incorrect operation (non-error operation rate).

The graph of FIG.11 shows the average value of the correct answer rates obtained by performing the operation test of using two strokes on six subjects. Here, the operation test for selectively using two strokes is a test in which the first stroke and the second stroke are input according to the test specifications within a predetermined time.

In this test specification, the input of the first stroke and the input of the second stroke are randomly repeated. The system to which the operation switch was connected detected strokes from the subject's input and compared the detection results with those specified in the test specifications.

The value on the horizontal axis in FIG.11 is the ratio of the load required for the second stroke to the load required for the first stroke (150 g). The value on the vertical axis is the operation accuracy rate when each of the above loads is set.

When the load required for the second stroke is about 1.67 times or more, as in FIG.11 1, the correct answer rate is 96% or more, and especially, the stable rate is 2.5 times or more. However, if the load required for the second stroke exceeds three times, the subject will feel heavy on the stroke. Therefore, the second stroke cannot be increased without limit.

FI G.12 is the result of the operation correctness test for one subject. In the test of FI G.12, the load required for the first stroke was changed to 100 g, 150 and ぴ 250 g, and the test was executed with the load of the second stroke changed for each. Have been. In this test, three to four measurements were performed for each load of the first stroke, and the average value of the accuracy rate was calculated. FIG. 12 is a graph plotting the average value. According to FI G.12, when the load required for the first stroke is 100 g, the load for the second stroke is about three times that, and the load required for the first stroke is 1

At 50 g and 250 g, if the load of the second stroke is set to about 2.5 times that, the accuracy rate stabilizes near 100%.

In any case, apply the second stroke to the load required for the first stroke.

If it is less than about 67 times, the accuracy rate drops rapidly.

As described above, according to the operation switch of the present embodiment, two strokes can be detected by the single button unit 4A. Also, by combining such button sections 4A and 4B, it is possible to make a transition from the standby state to four states.

In addition, according to the operation switch of the present embodiment, the installation position of the button portion 4A (or 4B) shown in FIG. 1 (a: b inside the straight line connecting the dome reversing springs 2A and 2B) By adjusting the ratio, the ratio between the load required for the first stroke and the load required for the second stroke can be set in a stepless manner.

In the operation switch of the present embodiment, the ratio of the load required for the first stroke to the load required for the second stroke is generally in the range of 1.7 or more and 5 or less. When two loads are set at a ratio in this range, the accuracy rate is stable at around 100%, and the second stroke does not become extremely heavy.

In the above embodiment, the dome reversing spring 2A (and 2B) is used for the spring portion. However, the embodiment of the present invention is not limited to such a configuration. Fig. 13 shows an example of an operation switch when other components are used.

In FIG. 13, the operation switch 20 is an example in which a rubber contact is used in place of the dome reversing spring 2A (and 2B) and the contact switch 5A (and 5B). The operating principle of the operation switch 20 is the same as that shown in FIGS. Even when the rubber contact switch is used, the spring repulsion force and the clinch are the same as when the dome reversing springs shown in FIGS. 1 to 3 are used. It is possible to obtain a sense of operation with a sense of click.

The operation switch 21 of FIG. 13 is an example in which a tact switch is used in place of the dome reversing spring 2A (and 2B) and the contact switch 5A (and 5B). Even when the tact switch is used, the repulsive force of the spring and the clicking sensation can be obtained as in the case of using the dome reversing springs shown in FIGS. 1 to 3.

The operation switch 22 shown in FIG. 13 is an example in which a leaf spring is used in place of the dome reversing spring 2A (and 2B), and the contact is composed of an open contact 23 and a metal contact 24. As described above, the operation switch according to the present embodiment can be manufactured by combining generally available smart parts.

The operation switch 25 of FIG. 13 is a modification of the operation switch 22, and the leaf spring 26 is integrated with the bridge component 3. With such a configuration, the number of components can be reduced.

In the above-described embodiment, two buttons 4A and 4B are provided as buttons operated by the operator. However, the embodiment of the present invention is not limited to such a configuration. FIG. 14 shows a configuration example of an operation switch having one button portion 4A (without the button portion 4B). This operating principle is the same as the case where one of the buttons 4A (or 4B) is used in the operation switch having the two button sections 4A and 4B described in FIGS. 1 to 3.

<< 2nd Embodiment >>

The second embodiment of the present invention will be described with reference to the drawings of FIGS. 15 to 17. FIG. 15 is a diagram showing a structure (standby state) of the operation switch according to the second embodiment, and FIG. 16 is a diagram showing a state of the operation switch at the first stroke. FIG. 17 is a diagram showing a state at the time of the second stroke.

In the first embodiment, the mounting position of the button portion 4A (or 4B) on the bridge component 3 is adjusted so that the load on the dome reversing spring 2A or 2B via the bridge component 3 becomes a predetermined ratio. It was set. That is, the position where the straight line connecting the dome reversing spring 2A and the dome reversing spring 2B is internally divided at a predetermined ratio is set as the mounting position of the button part 4A (or 4B). As a result, the dome reversing spring 2 A and the dome reversing spring The load applied to 2B is made uneven, realizing a 2-stroke operation switch.

In the present embodiment, instead of the buttons 2A and 2B, a lever that swings about a predetermined axis is used to realize a two-stroke operation switch. In the present embodiment, two strokes means that one operation (operation in one rotation direction) on the lever includes the first stroke and the second stroke. Other configurations and operations are the same as those of the first embodiment. Therefore, the same components are denoted by the same reference numerals, and description thereof is omitted.

FIG. 15 shows the structure of this operation switch. FIG.15 indicates an operation switch in a standby state in which no operation has been performed yet. As described above, in this operation switch, the lever 6 having the lever rotation axis 7 (hereinafter, simply referred to as the rotation axis) is provided on the bridge component 3. The rotating shaft 7 is fixed to the substrate 1, and the lever 6 swings around the rotating shaft 7.

Further, the rotating shaft 7 may be fixed to the bridge component 3. However, in this case, as shown in FIG. 15, the rotating shaft 7 is fixed to the bridge part 3 with the bottom of the lever 6 (hereinafter referred to as lever bottom 6 B) placed on the bridge part 3. Then, the lever 6 and the bridge part 3 cannot move relative to each other.

As a result, when the lever 6 is operated, the lever 6 and the bridge component 3 are easily lifted from the substrate 1. In order to prevent such floating, a cover for suppressing both ends of the bridge component 3 in the direction of the substrate 1 may be provided. The dome reversing springs 2A and 2B can be unequally loaded by the rotational force of the lever 6 with the contact point between the cover and the end of the bridge part 3 as a fulcrum, and the dome reversing springs 2A and 2B can be reversed in two stages. it can.

Further, a gap may be provided between the lever 6 (lever bottom 6B) and the bridge component 3 to fix the rotating shaft 7 to the bridge component 3. In this case, the lever 6 and the bridge part 3 are connected to each other until the operation part 6A is rotated in one direction with respect to the rotation shaft 7 and the bridge bottom part 6B contacts the bridge part 3. On "condition. In this state, the lever 6 and the bridge part 3 can move relative to each other. Further, after the bottom 6B of the bridge comes into contact with the bridge part 3, the lever 6 and the bridge part 3 are integrated with the dome reversing springs 2A, 2B (and ぴ Affects setting switches 5A and 5B). Also in this case, similarly to the above, if a cover for preventing the bridge component 3 from floating is provided, the dome reversing springs 2A and 2B can be reversed in two stages.

Alternatively, the rotating shaft 7 may be fixed to a lever, a bearing (not shown) may be provided, and the lever 6 and the rotating shaft may be rotated by a body. The bearing may be fixed to the substrate 1. However, the bearing may be fixed to the bridge component 3, and covers may be provided at both ends of the bridge component 3 to prevent floating.

The lever has an operation section 6A operated by an operator, and a lever bottom section 6B which rotates integrally with the operation section 6A and presses the bridge component 3. When the operator rotates the operation unit 6A of the lever 6 with respect to the rotation axis, the rotational power is converted into a pressing force on the bridge component 3 at the bridge bottom 6B, and the bridge component 3 is pressed.

When the pressing force exceeds a predetermined value, the dome reversing spring 2A close to the pressing portion (FIG. 16 (b)) is reversed. This completes the switching of the first stroke switch, turning on the contact switch 5A (FIG. 16).

When the operator further increases the load on the lever 6, the load on the inverted dome reversing spring 2A (the position indicated by (C) in FIG. 16) becomes a fulcrum. A counterclockwise rotating force is applied to the dome reversing spring 2B.

When the load exceeds a predetermined value, the dome reversing spring 2B reverses. As a result, the switching of the second stroke switch is completed, and the contact switch 5B is turned on (FIG. 17).

As described above, according to the operation switch of the present embodiment, two strokes can be detected with respect to the rotation operation by the lever 16.

<< Third embodiment >>

The third embodiment of the present invention will be described with reference to the drawings of FIGS. 18 to 20. FIG. 18 is a diagram showing the structure (standby state) of the operation switch according to the third embodiment, and FIG. 19 is a diagram showing the state of the operation switch during the first stroke. G.20 is a diagram showing a state at the time of the second stroke.

In the first embodiment, the button part 4 A provided on the bridge part 3 and the dome 2A and 2B realize a two-stroke operation switch. That is, the button portion 4A (or 4B) was attached at a position where the straight line connecting the dome reversing spring 2A and the dome reversing spring 2B was internally divided at a predetermined ratio.

As a result, the load applied to the dome reversing spring 2A and the dome reversing spring 2B was made uneven, and a two-stroke operation switch was realized. However, in this configuration, when the button section 4A is pressed and the dome inversion buttons 2A and 2B are both inverted, the button section 4B is pressed even if the button section 4B is not pressed. Moves in the same direction as 4 A (for example, pressing down button 4 A also pushes down button 4 B).

In the present embodiment, an operation button will be described in which the button 4B appears to maintain its position even when the button section 4A is pressed down. Other configurations and operations are the same as those of the first embodiment. Therefore, the same components are denoted by the same reference numerals, and description thereof is omitted.

FIG. 18 shows the structure of this operation switch. FIG.18 indicates an operation switch in a standby state in which no operation has been performed yet. This operation switch has a structure in which a bridge component 8 is further stacked on the bridge component 3. The bridge component 8 is in contact with the bridge component 3 at a predetermined contact surface. The bridge part 8 is provided with two button parts 4A and 4B.

Further, the operation button is covered with a case component (hereinafter, referred to as a housing 10) having openings 11A and 11B. Button portions 4A and 4B are exposed by openings 11A and 11B of housing 10.

FIG. 19 and FIG. 20 show the state of the operation switch when the button section 4A is pressed. Hereinafter, the operation principle of the operation switch will be described.

The bridge component 8 is in contact with the housing 10 at the contact position (the position indicated by (a) in FIG. 19) on the upper surface of the end near the button portion 4B. Therefore, when the operator presses the button portion 4A exposed from the opening portion 11A, the bridge component 8 rotates clockwise with respect to the paper surface with the contact position (a) as a fulcrum.

As a result, at the load point (b) from the bridge component 8 to the bridge component 3, the load due to the operation is transmitted to the bridge component 3. The load at load point (b) is Similar to the position of the button portion 4A in the configuration, the dome reversing springs 5A and 5B are pressed unevenly. Therefore, when the pressing load on the button section 4A by the operator exceeds a predetermined value, first, the dome reversing spring 5A is reversed (FIG. 19). This turns on contact switch 5A.

When the operator further increases the pressing load, a rotational force is applied to the bridge part 3 with the position (c) of the dome reversing spring 2A as a fulcrum and the load point (b) as a power point. When the pressing load exceeds a predetermined value, the dome reversing spring 2B reverses. As a result, the contact switch 5B is turned on.

As described above, the operation of the operation switch of the present embodiment is the same as that of the operation switch of the first embodiment, in that the contact switches 5A and 5B are turned on by two strokes by pressing the button 4A. .

As shown in Fig. 20, even if the bridge part 8 rotates clockwise around the fulcrum (a) by the pressing operation on the button 4A as shown in Fig. 20, it is close to the fulcrum (a). The position of button 4B is almost maintained. Therefore, unlike the case of the first embodiment, when the button 4A moves by the pressing operation, the button 4B does not move at the same time. For this reason, with the operation switch according to the present embodiment, it is possible to reduce the unnatural movement of the button that is not operated in response to the operation of the operator.

<< 4th Embodiment >>

A fourth embodiment of the present invention will be described with reference to the drawings of FIGS. 21 to 23. FIG. 21 is a diagram showing the structure (standby state) of the operation switch according to the fourth embodiment, and FIG. 22 is a diagram showing the state of the operation switch at the time of the first stroke. FIG. 23 is a diagram showing a state at the time of the second stroke.

In the first embodiment, the mounting position of the button part 4A (or 4B) on the bridge part 3 is adjusted so that the load on the dome reversing spring 2A or 2B via the bridge part 3 becomes a predetermined ratio. It was set. That is, the position where the straight line connecting the dome reversing spring 2A and the dome reversing spring 2B is internally divided at a predetermined ratio is defined as the mounting position of the button part 4A (or 4B). As a result, the loads applied to the dome reversing spring 2A and the dome reversing spring 2B are made uneven, and a two-stroke operation switch is realized. In the operation switch of the first embodiment, in the second stroke, FIG. With the load on the dome reversing spring 2 A shown in Fig. 3 (the position shown in (C) of FIG. 2) as a fulcrum, a load due to a counterclockwise rotational force is applied to the dome reversing spring 2B. Was.

In the present embodiment, the rotational force of the second stroke is generated using a fulcrum 13 A or 13 B provided at the end of the bridge component 3 as a fulcrum. In the present embodiment, a spring is further provided between the bridge component 3 and the dome reversing spring 2A (and 2B).

Other configurations and operations are the same as those of the first embodiment. Therefore, the same components are denoted by the same reference numerals, and description thereof will be omitted.

Further, this operation switch has a spring part 12 A between the bridge part 3 and the dome reversing spring 2 A. Similarly, this operating switch has a spring part 12B between the bridge part 3 and the dome reversing spring 2B.

The repulsion of these spring components 12 A and 12 B is stronger than the repulsion of the dome reversing springs 2 A and 2 B.

When the operator presses the button section 4A, the two dome reversing springs 2A and 2B become unequal due to the same principle as the operation principle described in the first embodiment (FIG. 1 to FIG. 3). Heavy load is applied. When the load exceeds a predetermined value, the dome reversing spring 2A reverses. This turns on contact switch 5A (FIG. 22). When the operator further increases the load on the button section 4A, the dome inverts counterclockwise rotational force toward the paper with the fulcrum section 13A at the point of contact (d)) with the board 1 (2). Loaded on B.

When the load exceeds a predetermined value, the dome reversing spring 2B reverses. This turns on contact switch 5B (FIG. 23). At this time, the spring component 12A provided between the bridge component 3 and the dome reversing spring 2A and the spring component 12B provided between the bridge component 3 and the dome reversing spring 2B are compressed. operation When the user presses the button 4B, the operation of the operation switch is the same.

As described above, according to the operation switch of the present embodiment, the operation of the fulcrum portion 13A (13B) can stably realize a two-stroke button operation.

Other configurations and operations are the same as those of the first to sixth embodiments. Therefore, the same components are denoted by the same reference numerals, and description thereof is omitted.

Fig. 31 shows a perspective view of this operation switch. This operation switch includes a dome reversing spring 2A and 2B mounted on the base plate 1, a bridge component 3 for bridging between the dome reversing springs 2A and 2B, and a see-saw unit provided on the bridge component 3. Has eight. In the present embodiment, the pressing members 3A and 3B are provided at the contact portions of the lower end of the bridge component 3 with the dome reversing springs 2A and 2B. The seesaw key 8 has a bearing hole 9 penetrating from the vicinity of the center of the front of the key shown in FIG. 31 to the back of the key, and accommodates the rotating shaft 7. The rotating shaft 7 is bent in an L shape, and is fixed to the substrate 1 at a base 7A. As a result, the seesaw key 8 rotates about the rotating shaft 7 with the relative distance between the center of the bearing hole 9 and the substrate 1 fixed, and the bottom of the seesaw key 8 (hereinafter referred to as the key bottom 8C). The dome reversing springs 2A and 2B are pressed through the bridge component 3, and the pressing member 3A (or the fulcrum 3B).

The rotating shaft 7 may be fixed to the seesaw key 8 and a bearing (not shown) may be provided so that the seesaw key 8 and the rotating shaft 7 swing together. The bearing may be fixed to the substrate 1.

Fig. 32 shows the standby state of this contact switch. As described above, this operation switch is provided with the seesaw key 8 having the rotating shaft 7 on the bridge component 3. The rotating shaft 7 is fixed to the substrate 1, and the seesaw key 8 swings around the rotating shaft 7.

The seesaw key 8 includes a pressing portion 8A operated by an operator (and a pressing portion 8B for operating the pressing portion 8A in a direction opposite to the pressing portion 8A across the rotary shaft 7), and a pressing portion 8A (8B ), And has a key bottom 8C that presses against the bridge part 3. When the operator presses the pressing portion 8 A (8 B) of the seesaw key 8, a rotating force is generated about the rotating shaft 7, and the rotating force is converted into a pressing force on the cartridge component 3 at the key bottom 8 C. Press the bridge part 3.

When the pressing force exceeds a predetermined value, the dome reversing spring 2A close to the pressing portion ((1 ^) in FIG. 33) reverses. This completes the switching of the switch of the first stroke, and the contact switch 5A is turned on (FIG. 33).

When the operator further increases the load on the pressing portion 8A, the operator moves toward the FIG. 33 with the load position on the inverted dome reversing spring 2A (the position indicated by (C) in FIG. 16) as the fulcrum. The counterclockwise rotation force is applied to the dome reversing spring 2B.

When the load exceeds a predetermined value, the dome reversing spring 2B reverses. This completes the switching of the switch for the second stroke, and the contact switch 5B is turned on (FIG. 34). Also, when pressing the pressing portion 8B, the operation switch The effect is similar.

As described above, according to the operation switch of the present embodiment, two strokes can be detected in response to the pressing operation of the seesaw key 8. The seesaw key 8 generates a two-stroke switch by causing a rotating action by the rotating shaft 7 to the operating part having a shape close to the key of the keyboard as compared with the case of using the lever 6 described in the second embodiment. be able to.

In the seventh embodiment, the operation switch that realizes the two-stroke operation using the seesaw key 8 and the bridge part 3 has been described. In the above embodiment, in the standby state (FIG. 33) of the operation switch, the entire lower surface of the seesaw key 8 (key bottom portion 8B) is in contact with the bridge component 3. However, implementation of the present invention is not limited to such a shape. For example, the structure may be such that a part of the lower surface of the key bottom 8B contacts the bridge component 3. FIG. 35 to FIG. 37 show the structure and operation of such an operation switch. As shown in these figures, the seesaw key 8 has legs 8D and 8E at the location where the lower surface comes into contact with the bridge component 3.

When the operator rotates the pressing portion 8A (8B) of the seesaw key 8 with respect to the rotation axis, the rotating power is converted to the pressing force on the bridge part 3 at the leg 8D (8E). Press the bridge part 3. The operation is the same as that of the key bottom portion 8C of the seventh embodiment.

In the seventh embodiment, the rotating shaft 7 is fixed to the substrate 1. Alternatively, the rotating shaft 7 may be fixed to the bridge component 3. However, in this case, as described in the lever 6 of the second embodiment, the seesaw key 8 acts on the dome inversion panels 2A and 2B integrally with the bridge component 3. In this case, an unbalanced load is applied to the dome reversing springs 2A and 2B due to the pressing on the pressing portions 8A and 8B. As a result, the operation switch of the present embodiment functions similarly to the operation switch of the first embodiment.

The mechanism of the two-stage stroke generation is the same as that described in the first embodiment. In the above seventh embodiment, the dome reversing panel 2 A and the

Pressing members 3A and 3B were provided at the contact points with 2B. However, as described in the first embodiment, the pressing members 3A and 3B are not necessarily required in the embodiment of the present invention.

<< Eighth Embodiment >>

The eighth embodiment of the present invention will be described with reference to the drawings of FIGS. 38 to 44. FIG. 38 is a structural view (standby state) of the operation switch according to the eighth embodiment, and FIG. 39 is a view showing a state when the first stroke of the button portion 4A of the operation switch is pressed. FIG. 40 is a diagram showing a state when the second stroke of the button unit 4A is pressed, and FIG. 41 is a diagram showing a state when the central button unit 4B of the operation switch is pressed. FIG. 42 shows the state when the first stroke of the button 4C of the operation switch is pressed, and FIG. 43 shows the state when the second stroke of the button 4C is pressed. FIG. 44 is a view showing FIG. 44, and FIG. 44 is a structural view of an operation switch according to a modification of the eighth embodiment.

In the first, third, fourth, or seventh embodiments, examples in which a two-stroke operation switch is realized by two contact switches have been described. In the present embodiment, an example is shown in which three contact switches realize two sets of two-storage operation switches. Other configurations and operations are the same as those of the above embodiment. Therefore, the same components are denoted by the same reference numerals, and description thereof is omitted.

In the present embodiment, a three-button two-stroke switch is configured using three contacts arranged on a substantially straight line.

FIG. 38 shows a structural diagram of an operation switch according to the eighth embodiment. F I G.

As in 38, the operating switches consist of the contact switches 5 A, 5 B and 5 C embedded in the board 1 and the dome reversing spring 2 A covering these contact switches 5 A, 5 B and 5 C. , 2B and 2C, the bridge part 3-1 bridging between the dome reversing springs 2A and 2B, and the bridge part 3-1 to bridge between the dome reversing springs 2B and 2C And a button part 4C provided on the bridge part 3-1 and a button part 4C provided on the bridge part 3-1. Of these, the button sections 4A and 4C at both ends provide a 2-stroke operation function. The center button 4B provides a normal one-stroke operation function. Of the three contact switches 5A, 5B, and 5C, the bridge part 3-1 is mounted on 5A and 5B (dome reversing springs 28 and 28).

The engaging part 3-2A of the bridge part 3-2 engages with the engaging part 3-1A of the bridge part 3_1. By this engagement, the bridge component 3-2 has a structure in which the contact switch 5C (dome reversing spring 2C) and the bridge component 3-1 are bridged. This engagement can be configured by, for example, a loose combination of the concave portion and the convex portion. However, instead of the combination of the concave and convex parts, the end of the ridge part 3-1 and the end of the ridge part 3-2 are mounted on a common swing shaft, and can swing around the swing shaft. May be combined in a proper state.

In the operation switch of the present embodiment, when the operator presses the button section 4A, similarly to the operation switch described in the first embodiment, first, the dome reversing panel 2A, and then the dome reversing spring 2 B is inverted. As a result, the contact switches 2A and 2B are turned on in this order, and the operation of two strokes is detected. At this time, the bridge parts 3-1 and 3-2 are engaged by a loose combination of the concave part and the convex part (or are connected so as to be able to swing around the swing axis). The operation of the button section 4A does not affect the dome reversing spring 2C and the contact switch 5C. Similarly, when the operator presses the button section 4C, the dome reversing panel 2C is first turned on, and then the engaging sections 3-2A and 3-2 are turned on, similarly to the operation switch described in the first embodiment. The dome reversing spring 2 B is reversed via 1 A. As a result, the contact switches 2C and 2B are turned on in this order, and a two-stroke operation is detected. Also in this case, the operation of the button portion 4C does not affect the dome reversing spring 2A and the contact switch 5A. As described above, the operation switch of the present embodiment provides two sets of two-stroke switch functions that operate independently of each other. Hereinafter, this operation switch is referred to as a three-contact switch.

Fig. 39 to Fig. 43 show changes in the state due to operations on the button parts 4A to 4C of the three-contact switch. As described above, FIG. 38 shows the standby state of the three-contact switch. In standby mode, press any of buttons 4A to 4C No force is applied. In this state, none of the dome reversing springs 2A to 2C is reversing. Therefore, the contact switches 5A to 5C are all in the off state.

Fig. 39 and Fig. 40 show the state when button part 4A is pressed. When the operator presses the button portion 4A on the bridge part 3-1, the pressing force acts unequally on the two dome reversing springs 2A and 2B, similarly to the operation switch of the first embodiment. First, the dome reversing spring 2A reverses. This completes the switching of the first switch and turns on the contact switch 5A (FI G. 39) o

When the operator further increases the load on the button section 4 A, the clockwise rotational force toward the FI G. 39 with the position of the load on the inverted dome inversion spring 2 A as a fulcrum, the dome inversion spring 2 B Is loaded.

When the load exceeds a predetermined value, the dome reversing spring 2B reverses. This completes the switching of the second stroke switch, and the contact switch 5B is turned on (FIG. 40). Thus, due to an unbalanced load on the dome reversing springs 2A and 2B, the contact switches 2A and 2B are turned on in two strokes.

Fig. 41 shows the state when the center button 4B is pressed. In the three-contact switch of the present embodiment, the button part 4B is an end of the bridge part 3-1.

(In the case of FIG.41, the right end as viewed in the figure). Therefore, when the operator presses the button portion 4B, most of the pressing force acts on the dome reversing spring 2B located substantially immediately below the button portion 4B. When the pressing force exceeds a predetermined value, the dome reversing spring 2B is reversed.

Furthermore, even if the pressing force is increased, the dome reversing spring 2A does not reverse. The bridge part 3-1 and the bridge part 2-2 are engaged with each other, but can swing with each other. Therefore, the pressing force on the button portion 4B does not act on the dome reversing spring 4C.

FI G.42 and FI G.43 show the states when button part 4C is pressed. When the operator presses the button part 4C on the bridge part 3-2, the two dome reversing springs 2C and 2B become unequal through the engaging parts 3-2A and 3-1A. The pressing force acts on the dome, and first, the dome reversing spring 2C is reversed. This completes the switching of the first stroke switch, turning on the contact switch 5C (FIG. 42).

When the operator further increases the load on the button section 4 C, the turning force counterclockwise toward the FI G. 42 with the load position on the inverted dome reversal spring 2 C as a fulcrum, the dome reversal spring Loaded to 2 B.

When the load exceeds a predetermined value, the dome reversing spring 2B reverses. This completes the switching of the switch for the second stroke, and the contact switch 5B is turned on (FIG. 43). Thus, due to the unbalanced load on the dome reversing springs 2C and 2B, the contact switches 2C and 2B are turned on in two strokes.

As described above, according to the three-contact switch of the present embodiment, a switch combining two mutually independent two-stroke switches can be configured. If such a three-contact switch is used for a mobile phone or information equipment, for example, in the work of selecting a list item, the upward (rightward) movement is moved to the button section 4A and the downward (leftward) movement is made. Movement can be assigned to the button section 4C. Then, when the operation of the first stroke is detected, the cursor is moved on the list at a normal speed (low speed), and is moved on the second stroke at a high speed (or a page). Also, the button section 4B may be assigned to a decision key for confirming the selection operation. Thus, the operability of the device can be improved with a small installation area by the three-contact switch of the present embodiment.

FIG. 44 shows the structure of a three-contact switch according to a modification of the present embodiment. In the eighth embodiment, an example has been described in which three two-stroke switches and one one-stroke switch are configured by three button units 4A to 4C. Alternatively, all three buttons 4A to 4C may be configured to operate as two-stroke switches.

In the configuration of FI G. 44, unlike the case of FI G. 38 to 43, the button 4B is not located at the end of the bridge part 3-1. For this reason, the operation of the button portion 4B is the same as that of the operation switch of the first embodiment, and the dome reversing springs 2A and 2B and the contact Acts as a two-stroke switch with switches 5A and 5B.

The effect when a pressing force is applied to the button portions 4A and 4C is the same as that described in FIGS. 39 to 43.

The engaging portions of the bridge parts 3_1 and 3-2 are the same as in the case of the eighth embodiment. That is, the concave portion and the convex portion may be gently engaged. Alternatively, the end 3_2A of the 3_2 may be formed in a claw shape and placed on the end of the bridge part 3-1. Alternatively, the bridge parts 3-1 and 3-2 may be pivotally mounted around the shaft member constituting the swing shaft.

In the eighth embodiment, the button portion 4A is provided at a position close to the dome reversing springs 2B and 2A on the bridge part 3-1, and the first stroke by the button portion 4A causes the dome reversing spring 2A. , And the dome inversion spring 2B is configured to be inverted by the second stroke.

Also, the button portion 4C is provided at a position closer to 2C than the dome reversing spring 2B on the bridge part 3-2, and the first stroke by the button portion 4C reverses the dome reversing spring 2C, and The dome reversing spring 2B is configured to be reversed by two strokes.

However, the position of the spring that is reversed in each of these strokes can be appropriately selected according to the arrangement position of the button portion 4A or 4C. For example, the button part 4A is provided on the ridge part 3-1 at a position close to the dome reversing springs 2A and 2B, and the first stroke by the button part 4A inverts the dome reversing spring 2B, and The dome reversing spring 2A may be configured to be reversed by two strokes.

In addition, the button part 4C is mounted on the ridge part 3-2. The dome reversing spring 2B is reversed by the first stroke by the button portion 4C, and the dome reversing spring 2C is reversed by the second stroke. Good. That is, in the three-contact switch of the present embodiment, the positions of the button parts 4A to 4C may be appropriately selected according to the object to be used, and the opening and closing order of the contact switches 5A to 5C may be appropriately defined. .
