  As described above, the conventional slide type multi-directional switch shown in FIG. 16 has four leaf springs 4 having a required bent shape as members for pressing the membrane switch constituting the contact input portion. Since it is necessary to provide a space for arranging these leaf springs 4, it is difficult to reduce the size.

  On the other hand, in small portable devices such as mobile phones, digital cameras, and music players that are equipped with this type of sliding multi-directional switch, the area in which switches are mounted is becoming smaller and smaller with the recent increase in display size. Therefore, downsizing of the switch is desired.

  In view of such circumstances, an object of the present invention is to provide a slide-type multi-directional switch that can be configured in a small size and has excellent reliability.

  According to the first aspect of the present invention, there is provided a configuration in which a plurality of contact input portions are provided, and by sliding the key top, the contact input portion in the sliding direction is pressed and inputted by the pusher that slides with the key top. In the slide type multi-directional switch, the plurality of contact input parts are a base film in which a plurality of lower electrode patterns are arranged on the circumference and a flexible film in which an upper electrode pattern opposite to the lower electrode patterns is formed. The spacer is composed of a central switch and an outer peripheral spacer that are positioned independently of each other at the central part and the outer peripheral part of the plurality of lower electrode patterns. The pressing force transmission member is arranged on the top, and there is one pusher. When sliding with the key top, It is intended to pressing the membrane switch by rides on the force transmitting member.

In the invention of claim 2, in the invention of claim 1, the central spacer is fixed to only one of the flexible film and the base film.
In the invention of claim 3, in the invention of claim 1 or 2, the central spacer is lower than the outer peripheral spacer.
According to the invention of claim 4, in the invention of claim 2, the central spacer has a ring shape.
According to a fifth aspect of the present invention, in any one of the first to fourth aspects, a switch that is operated by a key top pressing operation is disposed below the membrane switch.

  According to the present invention, the membrane switch constituting a plurality of (multi-directional) contact input portions is slid and pressed by a single pusher, and thus smaller than a conventional sliding multi-directional switch. Can be configured.

  In addition, by placing a pressing force transmission member on the membrane switch and pressing the membrane onto the membrane switch, the membrane switch can be pressed, so that the force of the slide operation can be reliably converted into pressing force. In this respect, a sliding multi-directional switch excellent in reliability can be obtained.

Embodiments of the present invention will be described with reference to the drawings.

In FIG. 2, 51 indicates a display. 3 is an enlarged view of the AA cross section in FIG. 1, and FIG. 4 is an exploded view of the sliding multidirectional switch 10 shown in FIG.

First, the configuration of each part of the sliding multidirectional switch 10 will be described with reference to FIGS.
The key top 11 that is slid by the operator is fixed by press-fitting into a cylindrical portion 12a formed at the center of the rubber 12 with a mounting shaft 11a that projects from the lower surface thereof. Has been. In this example, the key top 11 is pressed in addition to the slide operation.

  The rubber 12 is disposed on the cover plate 13 so as to cover the entire cover plate 13, and by covering the cover plate 13 with the rubber 12 in this way, a dustproof and dripproof structure can be easily realized in this example. It has become. The cover plate 13 has an opening 13a at the center of the upper surface thereof. A cylindrical portion 12a of the rubber 12 in which the mounting shaft 11a of the key top 11 is press-fitted and fixed to the opening 13a, and a skirt portion 12b around the cylindrical portion 12a. Is located.

  A pusher 15 is attached to the tip (lower end) of the attachment shaft 11 a of the key top 11 via a slide plate 14. A prismatic part 15a is formed on the upper surface of the pusher 15 so as to project, and the prismatic part 15a is inserted into the square hole 11b formed in the mounting shaft 11a of the key top 11 through the square hole 14a of the slide plate 14. It is fixed.

  The outer periphery of the slide plate 14 is located on the inner surface around the opening 13 a of the cover plate 13. In this example, a friction reducing sheet 16 for reducing the frictional force with the slide plate 14 is attached to the inner surface of the cover plate 13.

  Below the pusher 15, a membrane switch 20 that constitutes a plurality of contact input parts that are pressed by the pusher 15 is arranged. The membrane switch 20 is composed of a flexible spacer 21 and a base film 22 each having a required electrode pattern formed on opposite surfaces thereof, and a spacer interposed therebetween. 23 and the outer peripheral spacer 24. In FIG. 4, the central spacer 23 and the electrode pattern formed on the base film 22 are not shown.

  FIG. 5A shows the electrode pattern formed on the inner surface of the flexible film 21 (the surface facing the base film 22) with hatching. The flexible film 21 has a circular upper electrode. A pattern 21a is formed, and a connecting portion 21b derived from the upper electrode pattern 21a is further formed. As shown with dots in the center of the upper electrode pattern 21a, a center spacer 23 having a ring shape is provided in this example. In this example, the central spacer 23 is printed on the upper electrode pattern 21a.

On the other hand, FIG. 6 shows the structure of the base film 22, and in this example, the base film 22 has a central switch portion in which a contact pattern constituting a switch operated by pressing the key top 11 described later is formed. 22 is ₁ and the membrane switch 22 ₂ constituting the membrane switch 20 shall become more and the connecting portion 22 ₃ and the cable unit 22 ₄ connecting them. Although shown separately in the connecting portion 22 ₃ of the base film 22 in FIG. 4, the base film 22 is incorporated by being folded at the connection portion 22 _3.

As the membrane switch unit 22 ₂ of the base film 22 opposite to the upper electrode pattern 21a formed on the flexible film 21, is formed of four lower electrode pattern 22a to form a fan shape are arranged on a circle and, also at the end of the connecting portion 22 ₃ side are formed connecting portion 22b.

On the other hand, by the folding of the connecting portion 22 _3, the central switch 22 ₁ which is to be located on the lower membrane switch unit 22 ₂ is formed center contact patterns 22c and the peripheral contact pattern 22d for the metal dome, these center contact pattern 22c, the peripheral contact pattern 22d and the membrane switch unit 22 ₂ of the lower electrode pattern 22a, the connecting portion 22b is required wiring is formed and arranged in the cable unit 22 ₄ as shown in FIG. 6 through the through hole Connected to the terminal 22e. The connecting portion 22b and the peripheral contact pattern 22d are GND and are electrically connected to each other. Further, on the back side of the central switch unit 22 _first conduction been electrode pattern 22f is formed with a central contact pattern 22c as shown in Figure 6B.

A membrane switch unit 22 ₂ for the lower electrode pattern 22a is formed in the base film 22, the flexible film 21 to the upper electrode pattern 21a and the central spacer 23 is formed by laminating via an outer peripheral spacer 24, thereby the membrane A switch 20 is configured. At this time, an ACF (anisotropic conductive adhesive) 25 is disposed between the connecting portions 21b and 22b of the flexible film 21 and the base film 22, and the connecting portions 21b and 22b are electrically connected to each other by the ACF 25. Is done. The four lower electrode patterns 22a arranged to face the upper electrode pattern 21a come into contact with the upper electrode pattern 21a, so that slide signals in four directions (up, down, left and right) can be output. The center spacer 23 is positioned at the center of the four lower electrode patterns 22a of the base film 22, and the outer periphery spacer 24 is positioned at the outer periphery of the lower electrode patterns 22a. In this example, the central spacer 23 has a lower height than the outer peripheral spacer 24, and a gap is formed between the central spacer 23 and the base film 22 as shown in FIG.

  A ring-shaped pressing force transmission member 17 is affixed to the upper surface side of the membrane switch 20 (the outer surface side of the flexible film 21), and further, friction when the pusher 15 slides on the pressing force transmission member 17. A friction reducing sheet 18 for reducing the force is attached. The pressing force transmission member 17 functions to reliably convert the sliding operation of the pusher 15 into the pressing operation of the membrane switch 20, and in this example, a single-sided adhesive sheet is used.

A switch pusher 31 for pressing the metal dome is attached to the lower surface side (membrane switch portion 22 ₂ ) of the membrane switch 20 with a double-sided tape 32.

The membrane switch 20 having the pressing force transmission member 17 and the friction reducing sheet 18 attached to the upper surface side and the switch pusher 31 attached to the lower surface side using the double-faced tape 32 as described above is attached to the base 33. The two formed bosses 33a are inserted and positioned. The flexible film 21 constituting the membrane switch 20 are formed two holes 21c and oval cutout 21d are inserted respectively positioned on the boss 33a, similarly to the membrane switch unit 22 ₂ of the base film 22 A hole 22g and an oval cutout 22h are formed. The outer circumferential spacer 24 is formed with two oval cutouts 24a.

Central switch portion 22 ₁ of the base film 22 is positioned under the base 33, the metal dome 34 is disposed on the central switch unit 22 _1. Metal dome 34 is positioned on the peripheral contact pattern 22d of the outer peripheral portion is formed in the central switch unit 22 _1, and is fixed by the dome sheet 35.

Central switch portion 22 ₁ of the base film 22 is fixed on the rear plate 37 by means of a double-sided tape 36, the embedded base 33 thereon, 4 of the rear plate 37 with four bosses 33b formed on the lower surface side of the base 33 The base 33 and the rear plate 37 are fixed to each other by inserting into the respective holes 37a and caulking the tip of the boss 33b. The base 33 is formed with an opening 33c where the metal dome 34 and the switch pusher 31 are located. Note that the central switch portion 22 ₁ of the base film 22 one hole 22i and three oblong notch 22j through which a boss 33b is formed.

  Claws 33e are protruded from the four side wall portions 33d of the base 33, and the four locking holes 13b formed in the side wall surface of the cover plate 13 are locked to the claws 33e of the base 33, respectively. As a result, the base 33 and the cover plate 13 are fixed to each other. At this time, the two bosses 33 a formed on the upper surface side of the base 33 are press-fitted into the two holes 12 c formed in the rubber 12, whereby the rubber 12 is fixed to the base 33 across the cover plate 13. Is done.

  In the configuration as described above, the key top 11, the pusher 15 and the base 33 are made of a hard resin such as ABS, PC, PMMA, or POM. The rubber 12 is a silicone rubber. Instead of silicone rubber, thermoplastic elastomer, synthetic rubber, or the like can be used. The cover plate 13, the slide plate 14, the rear plate 37, and the switch pusher 31 are formed of a thin metal plate such as SUS. As the friction reducing sheets 16 and 18, for example, sheets whose surfaces are subjected to Teflon (registered trademark) processing are used. Note that the friction reducing sheets 16 and 18 are not necessarily required, and may be replaced by surface treatment of the sliding component itself.

  A PET film is used for the flexible film 21 constituting the membrane switch 20, and a conductive wiring (Ag, carbon, etc.) is printed to form a required wiring pattern (electrode pattern). The film is not limited to PET, and films such as PI and PC can also be used. For the outer periphery spacer 24, for example, a double-sided adhesive tape of a film base is used. An insulating resist ink is used for printing the central spacer 23. The base film 22 having a required wiring pattern is an FPC in which a required wiring pattern is formed of a copper foil on a PI film.

  Next, the operation of the sliding multidirectional switch having the above-described configuration will be described. FIG. 7 shows a state where the key top 11 is slid, and FIG. 8 shows a state where the key top 11 is pressed.

  As shown in FIG. 7, when the key top 11 is slid in the direction of the arrow, the pusher 15 fixed to the key top 11 also slides together with the key top 11, and the pusher 15 is provided with a pressing force transmission member 17. As shown in FIG. 7, the robot rides on the pressing force transmitting member 17 by continuing sliding. As a result, the pressing force transmission member 17 is pushed by the pusher 15 and displaced downward, and presses the flexible film 21. The flexible film 21 is deformed by this pressing and is displaced downward, whereby the upper electrode pattern 21a formed on the flexible film 21 contacts the lower electrode pattern 22a formed on the base film 22, They are conducted and a slide signal is output. When the slide of the key top 11 is released, the key top 11 returns to the initial position shown in FIG. The bottom edge of the pusher 15 is rounded (R-shaped) so that the pusher 15 slides smoothly and rides on the push force transmission member 17.

  On the other hand, as shown in FIG. 8, when the key top 11 is pressed down in the vertical direction, the switch pusher 31 that is pressed by the pusher 15 and is fixed to the membrane switch 20 is displaced in the vertical direction. The switch pusher 31 presses the metal dome 34. At this time, since the central spacer 23 is present at the center of the membrane switch 20 pressed by the pusher 15, the membrane switch 20 does not operate (does not conduct). When the metal dome 34 is pressed by the switch pusher 31, the metal dome 34 is reversed as shown in FIG. 8, whereby the central portion comes into contact with the central contact pattern 22 c formed on the base film 22 and the central contact pattern 22 c. And the peripheral contact pattern 22d are conducted through the metal dome 34, and a switch pressing signal is output. When the pressing of the key top 11 is released, the metal dome 34 returns to the original state, and thereby the key top 11 returns to the initial position shown in FIG. Note that the diameter of the surface of the pusher 15 that presses the membrane switch 20 is larger than the inner diameter of the ring-shaped central spacer 23, whereby the central spacer 23 reliably receives the pressing force of the pusher 15, and the membrane switch 20 is electrically connected. Is to be prevented.

  As described above, in this example, the membrane switch 20 constituting the plurality of contact input units that are input by the slide operation of the key top 11 is pressed by the single pusher 15 that slides with the key top 11. Therefore, the size can be reduced as compared with a conventional slide type multi-directional switch using four leaf springs as members for pressing the membrane switch as shown in FIG.

  Further, since the pressing force transmitting member 17 is disposed on the membrane switch 20, the force of the slide operation can be reliably converted into the pressing force with respect to the membrane switch 20 at a desired position. It is possible to provide a slide-type multi-directional switch that is excellent in stability and has stable performance.

  In addition, in this example, a switch that is operated by pressing the key top 11 is disposed below the membrane switch 20, so that various operations are possible. For example, as shown in FIG. 2, when the mobile phone 50 is mounted, the item selected by the slide operation can be determined by the push switch. In this example, the switch to be pressed is configured by arranging a metal dome 34 that reverses the click on the contact pattern formed on the base film 22, but instead of this, for example, a normal tact switch can be used. .

  In this example, the spacer in the membrane switch 20 is divided into a central spacer 23 and an outer peripheral spacer 24 so as to enable multi-directional pressing operation of the membrane switch 20 with one pusher 15 and are independent from each other. That is, there is no connection portion for connecting the central spacer 23 and the outer peripheral spacer 24. Thus, as described above, in the case of the slide type multi-directional switch in which the four lower electrode patterns 22a are formed on the base film 22 and the four contact input parts are input by the slide operation, as shown in FIG. The direction can be detected. FIG. 9A is a perspective view showing the lower electrode pattern 22a formed on the base film 22 and the central spacer 23 and the outer peripheral spacer 24 positioned thereon, and the central spacer 23 and the outer peripheral spacer 24 are hatched. is doing. Further, FIG. 9B shows the pusher 15 with cross-hatching with respect to FIG. 9A, and the moving direction (8 directions) is indicated by an arrow, and the pusher 15 can be moved under the same conditions all around. It has become.

  On the other hand, FIG. 10 shows the case where there is a connecting portion 26 for connecting the central spacer 23 and the outer peripheral spacer 24 as a comparative example in the same manner as FIG. 9. In this example, as shown in FIG. When the child 15 slides on the connecting portion 26, contact input cannot be performed and no slide signal is output.

  On the other hand, even when there is the connecting portion 26, for example, as shown in FIG. 11, the number of pushers 15 ′ is set to four, so that detection in eight directions is possible with four contact points. Therefore, it becomes difficult to provide a spacer under the pusher 15 ', and since there is no spacer, there arises a problem that a malfunction is likely to occur due to slight pressing of the key top 11 or rattling of the pusher 15'. Although it is not impossible to provide a spacer under the pusher 15 ′ with four pushers 15 ′, in that case, the outer shape of the entire slide type multi-directional switch becomes large, and the size can be reduced. Be inhibited.

Next, the center spacer 23 will be described in detail.
In this example, the central spacer 23 is printed and formed on the upper electrode pattern 21a of the flexible film 21 so as to form a ring shape, and is lower than the outer peripheral spacer 24 to form a gap with the base film 22. This has the effects and effects described in the following (1) to (4).

  (1) Since the center spacer 23 is not fixed to the base film 22 but only to the flexible film 21, the membrane switch 20 is in a state where the center portion is not restrained. Therefore, the switch ON load of the membrane switch 20 can be reduced even when the size is small as compared with the case where the central portion is restrained (when the central spacer 23 is also fixed to the base film 22). Since the ON load of the switch 20 is small, the membrane switch 20 can be turned on by a light slide operation.

  (2) Since the central spacer 23 is lower than the outer peripheral spacer 24, the sliding operation force is easily transmitted to the pressing force to the membrane switch 20. FIG. 12 schematically shows this state. In FIG. 12, the illustration of the pressing force transmitting member 17 and the friction reducing sheet 18 disposed on the membrane switch 20 is omitted.

  Since the central spacer 23 is low, the central portion of the flexible film 21 is displaced downward (sinks) as shown in FIG. The upper surface of the flexible film 21 is inclined. As a result of the sliding operation, the pusher 15 comes into contact with the inclined surface as shown in FIG. 12C, so that the sliding operation force is easily converted into a pressing force to the membrane switch 20. Further, since the central spacer 23 is lower than the outer peripheral spacer 24, the ON load of the membrane switch 20 can be reduced even if the membrane switch 20 is downsized, and the membrane switch 20 can be turned on by a light slide operation. .

  (3) Since the central spacer 23 is printed and formed, as compared with the case where an adhesive spacer such as a double-sided tape is used, even if it has a small area, no peeling or the like occurs and the reliability is excellent.

  (4) Since the center spacer 23 has a ring shape, the pusher 15 is stabilized. When the fine central spacer 23 is printed and formed, the center tends to be convex. For example, when the circular central spacer 23 'is printed and formed instead of the ring shape, the convex shape as shown in FIG. Thus, the pusher 15 tends to tilt in an initial state and becomes unstable. On the other hand, by making the central spacer 23 into a ring shape, it comes into contact with a circle (circumference) of a required size instead of a point as shown in FIG. 13A, and the pusher 15 is in an initial state. Stabilize. From this point, the central spacer is not limited to the ring shape, and may be composed of, for example, at least three point spacers arranged on the circumference. FIG. 5B shows an example in which the central spacer 23 ″ is constituted by four pointed spacers arranged on the circumference at equal angular intervals.

Next, another usage example (mounting example) of the sliding multidirectional switch according to the present invention shown in FIG. 14 will be described.
A small portable device such as a general cellular phone or a digital camera is equipped with a switch that is a combination of a four-way operation switch called a 5WAY switch and a central determination switch. In this example, a slide type multi-directional switch 10 'according to the present invention is mounted in the decision switch portion at the center of the 5WAY switch of the cellular phone 50' instead of the decision switch. In FIG. 14, reference numeral 52 denotes an outer peripheral key top for operating the four-way operation switch of the 5WAY switch.

FIG. 15 is an enlarged view of the AA cross section of FIG. 14, and the same reference numerals are given to portions corresponding to FIG.
In this example, the key top (center key top) 11 is bonded and fixed to a sheet-like rubber 12, and is supported by the rubber 12 so as to be slidable and pressable. The pusher 15 is bonded and fixed to the back surface of the rubber 12 below the key top 11 and interlocks with the key top 11. A ring-shaped outer peripheral key top 52 is incorporated on a flange 11 c formed on the key top 11, and is adhered and fixed to the rubber 12 in the same manner as the key top 11. Similar to the sliding multidirectional switch 10 shown in FIG. 3, a push switch using a membrane switch 20 and a metal dome 34 that reverses the click is disposed below the key top 11.

  According to the present invention, since it can be configured more compactly than the conventional slide type multi-directional switch, the slide type multi-directional switch 10 ′ is mounted in the determination switch unit at the center of the 5WAY switch in this way instead of the determination switch. The 5WAY switch can be configured without increasing the size, and can be small and include two sets of four-way switches and a central determination switch.
