Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a multidirectional switch used for a computer game machine or the like, and particularly to a multidirectional switch for preventing damage to a substrate. [Prior Art] A conventional multidirectional switch will be described with reference to FIG. The figure shows one part of the multi-directional switch of the controller,
2 is a key top, 3 is a circuit board, 4,4 ... is a key top 2
And a click clubber interposed between the substrate and the circuit board 3. The key top 2 has a keying portion on the upper surface of a disk-shaped base 5.
Are formed so as to project in the respective directions, and the keying portions 6, 6... Are exposed from the switch holes 8 of the case 7. In the center of the back surface of the base 5, a hemispherical protrusion 9
Is formed. Further, conductive movable contacts 10, 10... Are provided on the back surfaces of the click clubbers 4, 4,..., And fixed contacts 11, 11. , And directional switches 12, 12,... Corresponding to the keying units 6, 6,. When the character of the computer game is controlled to be moved, pressing the keying portion 6 in the direction of movement control compresses the click clubber 4 to move the movable contact 10 and the fixed contact.
11 comes in contact. When the direction switch 12 is turned ON, the movement control is performed. In this movement control, the protrusion 9 comes into contact with the upper surface of the circuit board 3, so that the key top 2 tilts toward the pressed keying unit 6. Therefore, it is possible to prevent the other keystrokes 6, 6,... That are not pressed from simultaneously descending, and to turn on the directional switch 12 in only one direction. [Problem to be Solved by the Invention] The conventional multidirectional switch described above prevents a plurality of directional switches from being simultaneously turned ON by contacting a protrusion formed on the back surface of the key top with the upper surface of the circuit board. However, since the projection hits the circuit board and the circuit board is deteriorated or damaged, the quality of the multi-directional switch or the controller of a computer game machine to which the multi-directional switch is mounted is deteriorated. It is causing the decline. Therefore, a technical problem to be solved in order to surely turn on the switch in only one direction and prevent the deterioration and damage of the substrate arises, and the present invention aims to solve the problem. I do. [Means for Solving the Problems] The present invention has been proposed to achieve the above-mentioned object, and a plurality of keying portions showing a certain direction are protruded on an upper surface of a base of a key top, and the key top and a substrate are provided. A click rubber is disposed between the key top and the key top to resiliently float above the substrate, and furthermore, the keyed portion of the key top is exposed from the switch hole of the case, and the switch hole is opened for each keyed portion. In a multidirectional switch in which a separator is provided between the switch holes, a groove is formed with a gap between the adjacent keying portions, and an upper surface of the keying portion is formed. The switch hole is formed so as to be inclined downward toward the center of the base, while the upper surface of the separator of the switch hole is curved toward the outer periphery with the central portion as the apex, and
The multi-directional switch is provided such that the apex is formed so as to be located at a substantially middle position of the height of the keying portion whose upper surface is inclined.

[Action]

In the present invention, an X-shaped groove is provided with a gap between keying portions independently protruding from, for example, four directions from the center of the upper surface of the base. Further, the upper surface of the keying portion is formed so as to be inclined downward toward the center. on the other hand,
The separator of the switch hole formed in the case is formed in an X-shape corresponding to the X-shaped groove between the keying portions, and
The upper surface is curved along the outer peripheral direction with the central portion of the separator as the apex, and the apex is formed so as to be located at a substantially middle position of the height of the keying portion whose upper surface is inclined. Therefore, when assembling the key top, the click rubber is placed on the circuit board, and the respective keying portions are connected to each other at the lower base, so that the switch holes provided in the case from the upper surface of the key top are provided. The keying portions can be assembled by inserting the keying portions so that the keying portions are inserted thereinto, and the assembling work is simplified. Furthermore, even if it is attempted to simultaneously press the keying portions, the operation of simultaneously pressing the keying portions by the separators, despite the fact that the separator interposed between the keying portions does not protrude upward from the keying portions, does not occur. It becomes almost impossible, and the keying operation for each keying unit is performed extremely smoothly. [Embodiment] An embodiment of the present invention will be described below in detail with reference to FIGS. In FIG. 1, reference numeral 20 denotes a controller. As shown in FIG. 1, a multi-directional switch 21 and AB switches 22 and 22 operate a computer game or the like, and other switches 23, 23... And so on. The multi-directional switch 21 is mounted on a circuit board as shown in FIG.
A click clubber 25, 25, 25, 25 and a key top 26 are mounted on the top 24, and the key top 26 is provided with switch holes 28, 28,... Of a case 27 of the controller 20 shown in FIG.
More exposed. The key top 26, as shown in FIGS. 3 and 4,
Keying portions 30, 30, 30, 30 are formed to protrude from the upper surface of a circular plate-shaped base 29. The keying portions 30, 30, 30, 30 are base 29
The X-shaped groove 31 is formed so as to protrude independently from the center in four directions, and to have a gap between the adjacent keying portions 30, 30. The keying portion 30 has a top surface slightly inclined downward toward the center of the base 29. Also, the back surface 29 of the base 29
a is formed substantially in a plane. Or, although not shown,
The rear surface of the base 29 is formed so as to be slightly inclined from the center to the peripheral edge. As shown in FIG. 5, the crucibles 25, 25, 25, 2
5 is integrally formed at a position corresponding to the keying portions 30, 30, 30, 30 shown in FIG. 3 and FIG. A movable contact 32 made of a conductive material is provided on the back of the head of the click clubber 25. Further, as shown in FIG. 6, fixed contacts 33, 33, 33, 33 are disposed on the upper surface of the circuit board 24 at positions facing the movable contacts 32, 32, 32, 32 shown in FIG. It is. On the other hand, as shown in FIGS. 1 and 7, switch holes 28, 28, 28, 28 are formed in the left side of the case 27 of the controller 20 along the outer periphery of the keying unit 30, There is a gap between the switch holes 28, 28, 28, 28 adjacent to each other, and an X-shaped separator 34 having the same shape as the groove 31 of the key top 26 shown in FIG. 4 is formed. The separator 34 is provided so as to be curved with its upper surface being curved with its center at the top. Thus, the click clubbers 25, 25, 25, 25 are mounted on the fixed contacts 33, 33, 33, 33 of the circuit board 24,
When the top 26 is placed on the top 25, 25, and 25, and the case 27 is mounted on the top of the top 26, the top 28 is mounted on the circuit board by the clip rubber 25 as shown in FIG.
24, and the keying portions 30, 30, 30, 30 of the key top 26
Are exposed through the switch holes 28, 28, 28, 28 of the case 27.
In addition, movable contacts 32, 32, 32, 32 are provided below the keying portions 30, 30, 30, 30.
And fixed contacts 33, 33, 33, 33 face each other,
35, 35, 35 are configured. At this time, the separator 34
Is loosely inserted into the groove 31 of the key top 26, and the height a of the apex of the separator 34 is located between the heights b and c of the oblique upper surface of the keying portion 30. Thus, when operating a character or the like in the computer game, the respective keys 30 of the key top 26 are pressed and pressed. At this time, the separator 34 prevents the two or more keying portions 30, 30, 30, 30 from being simultaneously pressed. Therefore, one directional switch corresponding to the pressed key unit 30
The above operation is performed when only 35 is turned ON. [Effects of the Invention] In the present invention, a switch hole for each keying portion is formed in the case, and a separator is protruded between the switch holes.
Since the upper surface of this separator is curved toward the outer peripheral direction with the central portion as the vertex, and the vertex is formed so that the upper surface is located at a substantially middle position of the height of the inclined keying portion, The separator does not interfere with an external object, and the simultaneous keying operation is disabled by the separator protruding from the center even if each keying portion is pressed and keyed at the same time. Thus, the operability of the multi-directional switch is improved. Therefore, the projections required in the conventional type are not required, and the respective keying portions are connected by the lower base, so that when assembling the keytop, the case is simply attached from the upper surface of the keytop. Since the assembling operation can be performed, the assembling work is facilitated. Further, since the key top does not contact the substrate even when the key top moves up and down, it is possible to prevent the damage and the deterioration of the substrate from being promoted, and furthermore, the precise dimensional accuracy used in the conventional type is required. Since the protrusion is unnecessary, it can contribute to improvement in productivity and cost reduction.
