Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multidirectional lever switch device used for a so-called joystick or the like having a lever that can be tilted in multiple directions.

[0002]

2. Description of the Related Art This type of switch device is used, for example, in a control device of a car navigation system. For example, by tilting a lever to the right, a map displayed on a monitor screen is scrolled to the right to It is used to change the display state so that the map scrolls upward by tilting.

The structure of the switch device is provided with a lever that can be tilted in multiple directions, a plurality of switches are arranged around the lever at equal intervals, and the switches are turned on by pressing the lever by tilting operation. It is designed to work.

The plurality of switches described above are wired in a matrix as shown in FIG. 12 to form a switch matrix circuit, and the switch matrix circuit is connected to the input terminals R1 to R5 of the known remote control IC1. ing.

The remote control IC 1 has two output terminals T1 and T2 for outputting a timing signal to a switch matrix circuit, and outputs parallel signals input to the data input terminals R1 to R5 at the timing signals t1 and t2. It has a function of converting into a serial signal and outputting from a transmission terminal (not shown). The switch matrix circuit has a data input terminal R1 of the remote control IC 1 according to the switch which is turned on when receiving the timing signals t1 and t2.
.About.R5 group is given parallel data, and the relationship between the pressed switch and the data bit is assigned as shown in Table 1, for example.

[0006] In Table 1, if the timing signal t1 is output from the timing signal output terminal T1 while the lever is tilted upward and the switch located on the upper side is pressed, the switches are input to the input terminals R1 to R5 of the remote control IC1. This indicates that the data “10000” is output from the matrix circuit.

[0007]

By the way, in the switch device of this type, since the levers can be tilted in multiple directions, adjacent switches may be simultaneously turned on depending on the tilting direction of the levers. .

However, in the conventional switch matrix circuit, the relationship between the group of switches that are turned on and the digital data given to the remote control IC 1 is set as shown in Table 1. Therefore, for example, the switches located on the upper side and the upper left side are arranged. If the switches located are pressed at the same time, the data "10001" will be output from the switch matrix circuit when the timing signal t1 is output from the output terminal T1. However, since this data is not defined in advance as is apparent from Table 1, the data code output from the transmission terminal is not recognized and the phenomenon that the map does not scroll in any direction occurs. .

If the switch located on the upper side and the switch located on the upper right are pressed simultaneously, data "10000" is output when the timing signal t1 is output, and data "00001" is output when the timing signal t2 is output. To be done. Then, the data code notifying that the upper switch has been pressed and the data code notifying that the upper switch has been pressed are output, so it is not possible to determine which switch was pressed and the scroll direction cannot be determined. .

In order to prevent the above-mentioned problems, four switches are arranged on the upper, lower, left and right sides of the lever, and if the switches located on the upper side and the right side are pressed at the same time, the data indicating the upper right direction is output. However, in the case of this configuration, when the stroke for tilting vertically and horizontally to push each switch and the tilting tilt to push the switches located on the upper side and the upper right side at the same time, for example, There is a difference between the stroke and the stroke, which causes a problem that the operability of the lever is not good.

The present invention has been made in view of the above circumstances, and the purpose thereof can be determined to either one of the switches even if the switches adjacent to each other are simultaneously pressed, and yet the operability of the lever is multidirectional. Lever switch device.

[0012]

In order to achieve the above-mentioned object, a multidirectional lever switch device of the present invention comprises a lever that can be tilted in multiple directions and a plurality of switches that operate in accordance with the tilting directions of the lever. And a switch matrix circuit configured to include digital data indicating which switch has operated in accordance with the tilting direction of the lever is output from the switch matrix circuit,
Digital data output from the switch matrix circuit when a switch corresponding to any one tilting direction is activated is output when a switch corresponding to a tilting direction that is on both sides of one tilting direction is activated. It is characterized in that it is configured so as to be the logical sum of the respective digital data (the invention of claim 1).

The switch corresponding to the one tilting direction is a two-circuit switch having two circuits and three contacts, and two circuits are simultaneously opened and closed. The corresponding switch is a one-circuit switch with one circuit and two contacts.
Each of the two circuits may be wired in parallel with the circuit of one circuit switch (the invention of claim 2).

Further, it is preferable that the switch corresponding to one tilting direction is assigned corresponding to a direction which is operated more frequently than the switch corresponding to the tilting direction in which the one tilting direction is adjacent to each other. (Invention of Claim 3).

Further, a lever which can be tilted in multiple directions, a plurality of switches which are provided at positions surrounding the lever, and a lever which is provided so as to be displaced in association with the tilting of the lever, are predetermined based on the tilting of the lever. The switch has a switch matrix circuit in which a plurality of switches are wired in a matrix, and which switch operates depending on the tilting direction of the lever. In the configuration in which the digital data indicating the above is output from the switch matrix circuit, the digital data output when the switch corresponding to any one tilting direction is operated in the switch matrix circuit is the one in the one tilting direction. On the other hand, each digital output when the switch corresponding to the tilt direction of the relationship of being on both sides is activated In addition to the logical sum of the data, the operating stroke of the switch in one tilting direction may be longer than the operating strokes of the switches which are adjacent to each other in one tilting direction. (Invention of Claim 4).

[0016]

According to the first aspect of the present invention, when the lever is tilted in any one direction and one switch corresponding thereto is operated, it is output when the switches located on both sides of the one switch are operated. The digital data that is the logical sum of each digital data is output.

For example, if the tilting direction of the lever and the digital data from the switch matrix circuit are set as shown in Table 2 below, "1100" is output when the switch located on the upper side is activated, and the upper left side is output. When the switch located at is activated, "1000" is output,
Also, when the switch located on the upper right side is activated, "0
100 "is output.

[0018] Here, the upper left direction and the upper right direction are both adjacent to the upper direction, and the data “110
0 "is the data" 1000 "allocated to the upper left direction
And the data “0100” allocated in the upper right direction are in the logical OR relationship.

Therefore, if the lever is tilted in the intermediate direction between the upper side and the upper left side and the switches located on the upper side and the upper left side are simultaneously operated, the data output when the upper side switch is pressed " 1100 "and the data" 1000 "that is output when the switch on the upper left side is pressed are output at the same time, but since the d1 bit is the same, the data" 1100 "is eventually output from the switch matrix circuit. Become. Therefore, if the upper switch and the upper left switch are pressed at the same time, it is considered that the upper switch is pressed and an abnormal operation is not caused. Further, when the lever is tilted in the intermediate direction between the upper side and the upper right side, it is considered that the upper switch is pressed in the same manner as described above, and an abnormal operation is not caused.

The logical sum in the present invention means a logical sum in a broad sense, and is synonymous with a narrow sense in positive logic, but is a synonym in a narrow sense in negative logic. For example,
The data output when the switch located on the upper left side is negative logic "0111", and the data output when the switch located on the upper right side is pressed is "101".
If it is 1 ", the data output when the switch located on the upper side is pressed may be" 0011 "which is the logical product of the above-mentioned data in a narrow sense.

According to the second aspect of the invention, when the two-circuit switch having the two-circuit and three-contacts is pushed by tilting the lever, the two circuits are simultaneously turned on. At this time, since the two circuits are wired in parallel with one circuit of the one-circuit switch located on both sides,
When the switch of 2 circuits 3 contacts is turned on,
The state is the same as when one circuit switch located on both sides is pressed at the same time.

By the way, according to the structure of claim 1, even if the lever is tilted in the intermediate direction of the two switches and both switches are simultaneously actuated, the switch corresponding to the preferential one tilting direction is always pressed. Considered to have been done. This means that stable operation is guaranteed as described above, but on the other hand, the operating area of the switch corresponding to the tilting direction that is prioritized is expanded, and the switch corresponding to other tilting directions is correspondingly expanded. It also reduces the operating area.
Such an operating characteristic is convenient when it is applied to a switch whose application frequency is different depending on the direction, because the frequently operated direction can be assigned to a switch having a wide operating area (claim). Invention of Item 3). However, in the case where there is no such situation and the operation areas in each direction are desired to be evenly allocated, inconvenience may occur.

On the other hand, when the lever is tilted in any direction,
When the actuating portion is displaced by a predetermined actuating stroke, the corresponding switch is actuated. Here, when the operating strokes for the respective switches are the same, if the lever is tilted between the adjacent switches, for example, the upper switch and the upper right switch are simultaneously pushed down by the operating portion. At this time, which switch is activated depends on the direction in which the lever is tilted. If the lever is tilted to the upper side of the intermediate position between the upper switch and the upper right switch, the upper switch operates first. This is effective, if you tilt it to the upper right side from the intermediate position,
The switch on the upper right activates first, which activates it. In this way, when the operating stroke is the same for each switch, the operating area becomes the same with the intermediate position of the adjacent switch as the boundary.

However, if the operating stroke for one of the adjacent switches is shorter than the operating stroke for the other switch, tilting the lever in the direction of the intermediate position between the two switches will necessarily result in the other switch having the shorter operating stroke. Will work first and this will take effect. Therefore, when the operating stroke of each switch is the same, the operating area of each switch is the same, but when the operating stroke is different for adjacent switches, the operating stroke is shorter. In contrast, the working area is widened and narrowed for long ones. Claim 4
The invention was completed based on these circumstances. In the configuration of claim 4, since the operation stroke of the switch set to be the logical sum of the output signals of the switches on both sides is set longer than the operation stroke of the switches located on both sides of the switch, priority is given to it. The tendency that the operating area of the switch corresponding to the tilting direction is widened is canceled.

[0025]

As described above, according to the multi-directional lever switch device of the present invention, even if the adjacent switches are operated at the same time, it is considered that only one of the switches is pressed. It does not cause any unnecessary operation. Further, since the stroke in each direction can be set in the same manner, the operability of the lever is improved.

According to the structure of claim 2, in addition to the above effect, the circuit is simplified because the logical OR state of the data is created by using the two circuit switches, and the structure of claim 3 is further provided. According to this, when adjacent switches are pressed at the same time,
Since it is always considered that the switch with the higher frequency is pressed, it is possible to obtain an effect that the switch can be operated without a feeling of strangeness.

According to the invention of claim 4, the digital data output when the switches corresponding to one tilting direction are actuated is the logical sum of the digital data output when the switches located on both sides are pressed. Even if it is configured so that the operating stroke for each switch can be made uniform by making the operating stroke of the switch corresponding to one tilting direction longer than the operating stroke of the switch located on both sides of the switch, the operating area for each switch can be made uniform. When the operating frequencies are the same, the operation can be performed without impairing the operation feeling.

The bottom plate portion 13 of the base 11 is formed with relief portions 13a at eight positions corresponding to the select switches 4 so as to avoid interference with the switch operating portions 9 by recessing the back surface of the bottom plate portion 13. A guide hole 13b is formed so as to communicate with the surface of the bottom plate portion 13 from the inside of the escape portion 13a. An actuating pin 14 having a flange at its base end is freely fitted into the guide hole 13b so as to be movable in a direction perpendicular to the printed circuit board 2 with its tip protruding toward the surface of the bottom plate 13. There is. The operating pin 14 is always pushed by the head portion 9b thereof due to the elastic restoring force of the elastic rising portion 9a of the switch operating portion 9 and is held in a state where the tip thereof is most protruded upward.

Further, a rectangular through hole 13c which opens so as to surround the set switch 3 is formed in the center of the bottom plate portion 13, and a rectangular cylindrical bearing bracket 15 is supported in the through hole 13c. It is rotatably supported by 13d. Furthermore, the tilt bracket 16 is rotatably supported by the support shaft 16c on the bearing bracket 15 along an axis orthogonal to the axis on which the bearing bracket 15 is rotatably supported. As a result, the tilt holder 16 is supported by the two axes orthogonal to each other, and can be tilted in any direction. Further, a flange portion 16a is formed on the outer periphery of the tilt holder 16, and in the neutral state where the tilt holder 16 is perpendicular to the printed circuit board 2, eight operating pins 14 fitted to the base 11 are provided. When the tilting holder 16 tilts while simultaneously contacting all the tips of the working pin 1, any of the eight working pins 14 is pushed by the flange portion 16a according to the tilting direction, and the working pin 1
The switch actuating portion 9 which is in contact with 4 is the elastic rising portion 9a.
It is adapted to move to the printed circuit board 2 side against the elasticity of.

The tilt holder 16 has a support hole 16 penetrating along the length thereof so as to reach from the tip end surface to the base end surface.
b is formed, and the leg portion 17a of the operation lever 17 is fitted into the support hole 16b. As a result, the operating lever 17 is supported with respect to the tilting holder 16 so that the leg portion 17a can freely move in the longitudinal direction and cannot rotate about the longitudinal direction, and the operating lever 17 tilts. The holder 16 and the holder 16 are tilted together. Further, the operation lever 17 is constantly urged upward by a return spring 18 which is a compression coil spring that is externally fitted and attached to the leg portion 17a.

A cover 23 is covered and fixed to the case 1 so as to cover the above-mentioned respective components, and a knob 17b of the operating lever 17 is formed on the front surface of the cover 23 in a circular shape concentric with the base 11. A window hole 23a having a larger diameter than the above is formed, and the knob portion 17b is exposed from this window hole 23a.

Next, the arrangement pattern of the fixed contacts 7 related to the select switch 4 will be described. Of the eight select switch groups 4 arranged at equal angular intervals, the four directions of up, down, left and right (the tilting direction of the operating lever 17). (The same applies hereinafter)
The select switch 19 corresponding to 3 is provided with three fixed contacts 19a, 19b, 19c in the form of a circle divided into three equal parts, and symmetrically on both sides with respect to the line connecting the select switch 19 and the set switch 3. Two fixed contacts 19a, 1
9b is arranged, and another fixed contact 19c is arranged on the outer peripheral side of each fixed contact 19a, 19b. These fixed contacts 19a, 19b and 19c use the fixed contact 19c as a common line together with the short-circuiting element 2
A circuit three-contact switch is configured. Further, the four select switches 20 located between the above-mentioned four select switches 19 correspond to four directions of obliquely extending upper right, lower right, lower left, and upper left, and each of them has two switches. The fixed contacts 20a and 20b are provided, and
A switch with two circuit contacts is configured.

Now, to describe the electrical configuration,
The eight select switches 19 and 20 are wired in a matrix as shown in FIG. 5 to form a switch matrix circuit 21 and are connected to the remote control IC 5.

The remote control IC 5 is a 6-bit input terminal K1 to which parallel digital data can be input.
K6 (K1 to K4 are used in this embodiment),
The digital data input from here is converted into a serial data code by an internal conversion circuit (not shown) and output from the transmission terminal Tx. Also, the input terminal K1
.. to K6 are provided with output terminals T1 to T3 (T1 is used in this embodiment) indicating that digital data can be input, and each of them has a logical value at a fixed timing.
1 "timing signals t1 to t3 (t1 is used in this embodiment). Further, the remote control IC 5 is internally provided with a clock generation circuit (not shown) for timing in each internal circuit, It is externally connected to the ceramic vibrator 22.

Next, the switch matrix circuit 21 will be described. One fixed contactor 19a located on the inner peripheral side of the select switch 19 in the upper direction is connected to the data input terminal K1 of the remote controller IC5 together with one fixed contactor 20a of the select switch 20 in the upper left direction, and the other fixed contact. The child 19b is 1 of the select switch 20 in the upper right direction.
The data input terminal K2 is connected together with one fixed contact 20a. Furthermore, the fixed contact 19 located on the outer peripheral side
c is the upper left and upper right select switches 20,
Each of the other fixed contacts 20b, 20b of 20 is connected to the output terminal T1 of the remote controller IC5. As a result, each switch circuit of the select switch 19 located on the upper side has the select switch 2 located on both sides thereof.
The wiring is arranged so as to be in parallel with the 0 and 20 switch circuits. Further, the remaining left and right select switches 19 are also wired so that the select switches 20 and the switch circuits located on both sides are parallel to each other in the same manner as described above.

Next, the operation of this embodiment will be described. When the knob portion 17b of the operation lever 17 in the neutral state is tilted upward, the operation lever 17 and the tilt holder 16 tilt, and the flange portion 16a pushes the operating pin 14 positioned in the tilting direction to the operating pin 14. The short-circuit element 10 of the switch actuating portion 9 which is pressed and elastically deformed has the fixed contact element 19 of the select switch 19 located on the upper side as shown in FIG.
The two fixed contacts 19a, 19b located on the inner peripheral side and the fixed contact 19c located on the outer peripheral side are short-circuited to be in contact with each other, and the respective switch circuits are in the ON state. Becomes

When the timing signal t1 ("1") is output from the terminal T1 of the remote control IC 5, the fixed contacts 19a, 19 of the select switch 19 located on the upper side.
The logical value "1" is output from b and input to the input terminals K1 and K2 of the remote control IC5. At this time, the input terminals K3 and K4 to which nothing is input are "0" because they are pulled down by the resistor in the remote control IC5, and digital data "is input to the input terminals K1 to K4 of the remote control IC5".
1100 ″ is input. Then, the data input to the remote control IC 5 is converted into a serial data code for notifying that the select switch 19 located on the upper side is pressed and output from the transmission terminal Tx. And is transmitted via the buffer 24. Similarly, when the other select switches 19 and 20 are pressed, digital data is output, and the relationship is as shown in Table 2.

Here, since the operation lever 17 can be tilted in any direction, depending on the tilting direction, two adjacent select switches 19 and 20 may be pressed simultaneously. For example, when the upper select switch 19 and the upper left select switch 20 are simultaneously pressed,
Digital data "1100" is output by pressing the select switch 19 located in the upper direction, and digital data "1000" is output by pressing the select switch 20 located in the upper left direction. In this case, d
Since both of the 1 bits are "1", the switch matrix circuit 21 ends up selecting switch 19 in the upward direction.
The digital data "1100" indicating that is pressed is output. Therefore, if the upper select switch 19 and the upper left select switch 20 are pressed at the same time, it is considered that the upper select switch 19 is pressed, and that the two select switches are pressed. It does not lead to abnormal operation. If the operation lever 17 is tilted in the intermediate direction between the upper direction and the upper right direction and the select switches 19 and 20 located in the upper direction and the upper right direction are simultaneously pressed, the digital data "1100" is output in the same manner as described above. There is no case where an abnormal operation is caused by outputting the output and assuming that the select switch 19 in the upward direction is pressed.

As described above, according to this embodiment, even if the adjacent select switches 19 and 20 are simultaneously pressed, it is considered that only one select switch 19 is pressed. It does not cause any unnecessary operation. Further, since the strokes in each direction can be set similarly, the operability of the operation lever 17 can be improved.

Further, since the logical sum state of the digital data is created by using the select switch 19 having two circuits and three contacts, the circuit becomes simpler and further, when the adjacent select switches 19 and 20 are simultaneously pressed. Since it is considered that the select switch 19 located in the up, down, left, and right directions, which is the select switch with the higher frequency, is pressed,
It can be operated without any discomfort.

<Second Embodiment> A second embodiment of the present invention will be described below with reference to FIGS. 6 to 8. The difference between the present embodiment and the first embodiment is that in the first embodiment, the operating stroke of the flange portion from the tilting of the tilting holder to the contact of the short-circuit element with the fixed contact element is different for each select switch. Although configured to be the same, in this embodiment, "
The operation strokes for the select switches located on "up", "down", "left" and "right" are operated for the select switches located on the "upper right", "lower right", "upper left" and "lower left" which are adjacent to them. Since the switch matrix circuit and the like are the same, the same parts are designated by the same reference numerals and the description thereof is omitted here.

As shown in FIG. 6, on the lower surface of the flange portion 32 of the tilt holder 31, "upper", "lower", "left", "right".
A recess 32a is formed at a position corresponding to the select switch 33 located at. As a result, as shown in FIG. 7, when the tilt holder 31 is in the neutral state, for example, "up"
A certain gap is provided between the flange 32 and the upper end of the operating pin 34 of the select switch 33 (right side in the drawing) located at. Further, the upper end of the operation pin 36 of the select switch 35 (left side in the figure) located at the "upper right" contacts the lower surface of the flange portion 32 as in the first embodiment.

Now, from the neutral state of the operating lever, "upper right"
When tilted in the direction, the actuating pin 36 is immediately pushed by the flange portion 32 of the tilt holder 31 as the operation lever tilts. The upper end of the operating pin 36 is the flange 32.
This is because it is in contact with the lower surface of the. Then, when the operation lever is further tilted, the switch actuating portion 37 is elastically deformed and the short-circuit element 38 contacts the fixed contact element 39, and the fixed contact element 39 is brought into conduction, as in the first embodiment.

Next, when the operation lever is tilted in the "up" direction, the tilt holder 31 tilts in the same manner as described above, but since a certain gap is provided between the operation pin 34 and the flange portion 32, the operation is performed. The pin 34 is not immediately pushed by the flange portion 32 when the operation lever is tilted, but is pushed after the operation lever reaches a predetermined tilt angle. And
When the operating lever is further tilted, the switch actuating portion 37 is elastically deformed and the short-circuit element 38 comes into contact with the fixed contact element 39, so that the fixed contact element 39 becomes conductive.

Here, observing the operation stroke of the flange 32 until the operation lever tilts from the neutral state and the short-circuit element 38 contacts the fixed contact element 39,
Compared to when the operating lever is tilted in the “upper right” direction,
The working stroke is longer when tilted in the "up" direction. This is due to the selection switch 35 located in the "upper right".
This is because the operating pin 36 of (1) is pushed together with the tilting of the tilting holder 31, whereas the operating pin 34 of the select switch 33 located "up" is pushed by the gap due to the recess 32a.

For this reason, for example, if the operating lever is tilted approximately in the intermediate direction between the select switches 33 and 35 located at the "upper" and "upper right", first, the actuating pin 36 located at the "upper right" is located at the flange portion. It will be pushed by 32 and then the actuating pin 34 located "up" will be pushed. The actuating pin 36 located on the "upper right" elastically deforms the switch actuating portion 37 to bring the short-circuit element 38 into contact with the fixed contact 39, but the actuating pin 34 located on the "upper" slightly moves the switch actuating portion 37. Only by elastically deforming, the movement of the operation pin 36 is restricted by the previously pushed operation pin 36, so that the short-circuit element 38 does not contact the fixed contact element 39.

That is, when the operating lever is tilted in the substantially intermediate direction between the select switches 33 and 35 located at "upper" and "upper right", the select switch 35 located at "upper right" is actuated, and "up" Select switch 33 located at
Will not work. Therefore, as shown in FIG. 8, the operating region A for the select switch 33 located "up" is narrower than the operating region B for the select switch 35 located "upper right".

Further, in the vicinity of the boundary between the operating area A and the operating area B, two select switches 33, 3 adjacent to each other are provided.
Uncertainty region C in which 5 may be pressed simultaneously to operate
(Hatched area in the figure). In the uncertain region C, as in the first embodiment, the digital data output when the select switch 33 located at "up" is pressed is the select data located at "upper right" and "upper left" on both sides. Since it is the logical sum of the digital data output when the switch 35 is pressed, it is always considered that the select switch 33 located "up" is operated with priority.

By the way, with the configuration of the first embodiment, 2
Even if the operation levers are tilted in the middle direction of the two select switches and both the select switches are operated at the same time, it is always regarded that the select switch corresponding to the one preferential tilt direction is pushed. This means that stable operation is guaranteed as described in the first embodiment.
On the other hand, the operating range of the select switch corresponding to the preferential tilting direction is expanded, and the operating range of the select switch corresponding to the other tilting directions is narrowed accordingly. Such an operating characteristic is convenient when it is applied to a select switch that is used for different frequencies depending on the direction, because the frequently operated direction can be assigned to a select switch that has a wide operating range. . However, in the case where there is no such situation and the operation areas in each direction are desired to be evenly allocated, inconvenience may occur.

However, in the present embodiment, the operation stroke of the select switch 33 located "up" which is the select switch corresponding to the preferential tilting direction is activated by the operation of the "upper right" select switch 35 located next to it. By setting it longer than the stroke, as described above "
Since the operating area of the select switch 33 located on the "upper" is narrowed and the operating area of the select switch 35 located on the "upper right" is widened, the "up" which is the select switch corresponding to the preferential tilt direction. The tendency that the operating range of the select switch 33 of FIG.

Therefore, in order to guarantee a stable operation in the uncertain region, the digital data output when the select switch 33 corresponding to one tilting direction is actuated is pressed when the select switches 35 located on both sides are pressed. In the case where the select switches 33 and 35 are operated at the same frequency because the operation areas for the select switches 33 and 35 can be made uniform even if the logical sum of the digital data output to Can be operated without impairing the sense of operation.

The present invention is not limited to the above-described embodiments, but can be modified and implemented as follows, for example, and these are also included in the technical scope of the present invention. (A) In the second embodiment, the concave portion 32a is formed on the lower surface of the flange portion 32 of the tilting holder 31, so that the operating strokes for the select switches 33 and 35 are different. However, the configuration is as follows. You may.
The same parts as those in the above embodiment are designated by the same reference numerals and the description thereof will be omitted.

A. As shown in FIG. 9, "upper" and "
Select switch 41 located at "bottom", "left", and "right"
The length of the operating pin 42 (on the right side in the drawing) is made shorter than the length of the operating pin 44 on the select switch 43 (on the left side in the drawing) located at "upper right", "lower right", "upper left", and "lower left". . As a result, a certain gap is provided between the upper end of the operating pin 42 of the select switch 41 located “up” or the like and the lower surface of the flange 45. When the operating lever is tilted, for example, in the "up" direction, the actuating pin 42 is not immediately pushed by the flange portion 45 with the tilting of the operating lever, but is tilted slightly before being pushed. Therefore, the operation stroke for the select switch 41 located "upper" is longer than that of the select switch 43 located "upper right" when the operation pin 44 is pushed as the operation lever is tilted, as in the above embodiment.

B. As shown in FIG. 10, in the select switches 51 (left side in the drawing) located at “upper right”, “lower right”, “upper left”, and “lower left”, the thickness of the back surface 52a of the head of the switch operating unit 52 is "Up down left right"
In the select switch 53 (right side in the figure) located at the position above the head back surface 54a of the switch operating portion 54, and the distance between the short-circuit element 55 and the fixed contact element 56 is "up" or the like. Make it shorter than one.

As a result, for example, when the operating lever is tilted in the "upper right" direction, the operating pin 57 of the select switch 51 located in the "upper right" is pushed by the flange portion 58, but the short-circuit element 55 is pushed only slightly. Since the fixed contact 56 and the fixed contact 56 are in contact with each other, the operation stroke thereof is shorter than that for the select switch 53 when tilted, for example, in the "up" direction. As a result, the operating stroke of the select switch 53 located "up" is longer than the operating stroke of the select switch 51 located "upper right".

C. As shown in FIG. 11, "upper" and "
Select switch 61 located at "down", "left", and "right"
At the right side in the figure, the head portion 62 of the switch operating portion 62
The thickness of a is "upper right", "lower right", "upper left", "lower left"
The thickness of the head portion 64a of the switch operating portion 64 of the select switch 63 (left side in the drawing) located at is reduced to a gap between the operating pin 65 and the flange portion 66.

Thus, for example, when the operating lever is tilted in the "up" direction, the operating pin 65 is not immediately pushed by the flange portion 66 but is slightly tilted and then pushed, so that the operating stroke is reduced. For example, the operation stroke of the select switch 63 located at the "upper right" is longer than the operation stroke when the operation pin 65 is pushed along with the tilt.

(B) In each of the above-described embodiments, the case where the number of select switches arranged on the annular area is eight has been described, but the present invention has a number of switches other than eight. It can also be applied in some cases. In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.
