  Below, the example of the embodiment of the present invention is described using FIGS. 1 and FIG. 2 (a) are perspective views of a light guide 30 (300, 30C) constituting the main part of the present invention, and FIG. 1 is a perspective view seen from obliquely above, FIG. 2 (a). FIG. 3 is a perspective view seen from obliquely below. FIG. 4 is a side sectional view showing a state in which the light guide 30 (300, 30C) is sandwiched between the substrate 10 and the panel 20, and a plurality of light guides are also provided in the front and back direction of the paper surface. ing. In FIG. 4, a plurality of embodiments are shown simultaneously. The light guide 30 (300, 30C) includes a truncated cone-shaped main body 31 made of a transparent or translucent resin material, a skirt portion 32 having a skirt shape for supporting the main body 31, and a top portion including the tip of the main body 31 (see FIG. A light emitting display portion) 33, a shoulder portion (locking portion) 34 at the boundary between the top portion 33 and the main body 31, and a base portion 38 at the skirt of the skirt portion 32. This base part 38 is a type 1 in which the base part of a single light guide 30 is formed in a flange shape, and a plurality of light guides 30 (300, 30C), 30 (300, 30C), etc. There is a type 2 that is connected and integrally formed in common with the base portion. In FIG. 1, type 1 is represented by a solid line, and type 2 is represented by a one-dot chain line. “A” in FIG. 4 indicates the type 1 and is shown on the left in FIG.

  As shown in the relationship diagram, the inside of the skirt portion 32 is hollow, its top surface 35 is configured in parallel with the substrate (installation panel / installation member) 10, and a dome-shaped recess 351 is formed at the center of the top surface 35. The small substrate with chip 50 is fixed to the top surface 35 with a conductive adhesive so that the chip of the LED 12 is fitted in the recess 351. As shown in FIG. 2 (b), the small substrate 50 is made of a flexible film made of a resin such as polyethylene having circuit patterns P1 and P2, and the LED chip is previously integrally formed with a conductive adhesive. Keep it. The small substrate 50 is fixed to the top surface 35 with the top surface 35 facing downward, for example, by means of an automatic insertion machine, substrate recesses 352 corresponding to the dotted lines 52 and 53 in FIG. 2B (see FIG. 4). The conductive adhesive is dropped at a predetermined point, the small substrate 50 is chucked with the tip of the arm, and the concave portion 353 of the substrate concave portion 352 corresponding to the mark protrusion 51 is confirmed by the sensor, and the small substrate 50 is mounted on the concave portion 352. Just place it. The small substrate 50 may be attached to the top surface 35 by hand, of course, but also in this case, the work efficiency is improved by providing the mark protrusions 51.

  The side surface of the skirt portion of the light guide is constituted by a side wall 36 including a thin portion 37, and the side wall 36 mainly has elasticity. When the light guide is sandwiched between the substrate 10 and the panel 20, the compression ratio of the skirt portion 32 changes due to the elasticity of the skirt portion 32, and can be arbitrarily set within the range of d1 to d3 in FIG. Can be held at a height of On the inner surface of the skirt portion, circuit patterns P3 and P4 that are power supply paths to the LEDs 12 are provided in pairs from the lower surface of the base portion 38 to the top surface 35 through the inner surface 361, and the base without this pattern is present. Protrusions 39 and 39 with hooks to the substrate 10 are provided at two points of the part. Protrusions 356 and 358 projecting in the direction of the substrate 10 are provided on the periphery of the top surface 35. This is a force-insensitive light guide in a display having no switch as shown in FIG. It serves as a stopper for protecting the LED 12 and the small substrate 50 against body sinking displacement, and acts as a movable contact projection in a switch-equipped display as shown in FIG.

  As shown in FIG. 3, circuit patterns as power supply paths to the LEDs 12 are provided on the substrate 10 as a pair along the lower surface of the skirt portion 32 in a circular shape, an arc shape, or a horseshoe shape. Since it is desired to use a LED with high brightness as much as possible, in order to increase the current capacity accordingly, the pattern is formed by applying carbon patterns P8 and P9 on metal patterns P6 and P7 such as copper and silver. Become. Between the end portions of the patterns P8 and P9, through holes 14 and 14 into which the holding protrusions 39 are press-fitted are provided. P5 is a general copper foil circuit pattern.

  As described above, the type 1 indicator has been described with reference to “A” and the like in FIG. 4. However, the type 2 indicator has a base portion as shown in “B” in the center and “C” on the right in FIG. A plurality of light guides 300 and 30C are integrally connected to each other at 38, and the base part 38 is like a plain in an LED-only light guide ("C") having no switch function. The only difference is that the difference is the same as that of the left “A” light guide, and the description of the configuration is omitted. The central display “B” has a switching function. The difference from the left “A” is that the configuration of the pattern applied to the inner surface of the skirt portion is different from that of the substrate.

  The configuration is shown in FIG. 5. FIG. 5 (a) is a pattern plan view of a conductor (fixed contact) applied to the substrate 10, and FIG. 5 (b) is a conductive pattern shown in “B” of FIG. It is the top view which looked at the light body from the lower side. As shown in FIG. 4B and FIG. 5A, the substrate 10 is provided with the same circuit pattern P5 as that of FIG. 3 as a power supply path to the LED 12, and corresponds to the lower surface of the skirt of the light guide 300. Thus, there are provided patterns P88 and P99 which are substantially the same as the patterns P8 and P9 in FIG. 3 (the counter interval is wider in FIG. 5A). These patterns are provided so as to face each other, electric circuit patterns 83, 84 for the fixed contacts 81, 82 are interposed between the faces, and the fixed contacts 81, 82 are arranged in pairs in the upper and lower directions in the drawing, It is formed in a comb-teeth shape and is meshed with each other. The patterns 81 a and 82 a that connect each pair of fixed contacts are arranged so as to avoid the conductive portion on the light guide top surface 35. Furthermore, the substrate 10 is provided with through holes 93 corresponding to the light guide holding projections 39 with the flanges at appropriate intervals.

  About the light guide 300, the patterns 61 and 62 which relay the electric circuit from the board | substrate 10 shown to Fig.5 (a) are given to the lower surface of a skirt part in horseshoe shape. This pattern is applied to the top surface 35 via the inner surface 361 and is coupled to the pattern of the small substrate 50. A conductive pattern is not provided between the joint portions of the horseshoe patterns 61 and 62, and is secured as a passage to the fixed contact. The movable contacts 66 and 67 are provided on the surfaces of the protrusions 356 and 358 that act as stoppers in the case of a light guide with only a display. The movable contacts 66 and 67 are formed, for example, by applying a conductive ink containing carbon or silver powder to the portion shown in the drawing and drying.

  The panel 20 is provided with through holes 21 for the display unit of the display unit composed of the light emitter 12 and the light guide 30 (300, 30C). A light guide retainer 22 is extended in the direction toward the substrate. In the display having no switch (“A” in FIG. 4 and “C” in FIG. 4), the opening surface of the through hole 21 is narrow and the horizontal cross section is a uniform circle. In FIG. 4 “B”), the opening surface of the through-hole 21 has a mortar-shaped opening 211, and is engraved so that a sufficient stroke movement is possible when the light guide is pressed during switch operation. It is out. Further, the panel 20 is provided with a plurality of bosses 26 for fixing the substrate integrally from the panel back surface 28, but the bosses existing on the left side and the front and back direction of the paper surface are omitted. A screw hole 261 is provided on the lower surface of the boss 26.

  The display shown in FIG. 4 is assembled as follows. First, the light guides 30, 300, and 30 </ b> C are fixed to the substrate 10. As the fixing means, the flange portion of the protrusion 39 shown in FIG. 1 is pressed and penetrated into the hole (through holes 14 and 93) of the substrate. In this case, an adhesive may be applied to the lower surface of the base portion 38 and attached to the substrate instead of the flange portion. When the substrate with light guide 10 is brought close to the panel back surface 28 and each light guide top portion 33 is inserted into the through hole 21 so that the surface slightly protrudes from the panel 20, each shoulder portion 34 is formed. It contacts the lower surface 23 of the light guide holder 22.

  At this time, when the distance D between the substrate 10 and the panel 20 is large (“A”), the skirt portion 32 is slightly compressed in the vertical direction and moves as “B” and “C”. Accordingly, the thin-walled portion 37 is mainly deformed and the degree of compression is increased. As shown in FIG. 4, such a state is a state in which the substrate 10 and the panel 20 such that the distance D becomes smaller as going to the right side are non-parallel, and in such a non-parallel state, The right substrate end 18 is fixed to the boss 26 protruding from the lower surface of the panel by the screw 40 through the screw hole 16. On the left side, the substrate 10 is fixed to the panel 20 by fixing means (not shown) having the same structure as that of the right side where the length of the boss is long.

  In the embodiment of FIG. 4 assembled as described above, D = d1 when the substrate-to-panel distance D is “A”, D = d2 when “B”, and D = d3 when “C”. As described above, the height varies according to “A” to “C”, and the height of the skirt portion correspondingly changes, so that the height of the light guide body also varies from d1 to d3. Thus, since the installation height of the light guide to the substrate is made variable, the light guides of a plurality of displays having different distances D can be used in common with the same object. In addition, since the LED is fixed to the light guide side, even if the overall length of the light guide changes, the LED luminance viewed from the panel side can be made unchanged if the supply voltage or current is the same.

  In addition, in the display with a switch shown in “B” of FIG. 4, the LED luminance can be kept constant even when the skirt portion is deformed during switching. Therefore, regardless of whether the switch (light guide) starts to be pressed, halfway, end of push, halfway after release, halfway from release, or completely released after the end of push, display with a switch with constant brightness Can be realized.

  Furthermore, a bare light guide that is not provided with a conductor pattern can be commonly used for either a light guide with a switch or a light guide without a switch, and any of the above can be achieved depending on the application of the pattern. In addition, by using the same conductor pattern as described above, the pattern is applied to almost the entire surface excluding a slight separation band for switching, and the LED is not mounted. It can also be made into a body. That is, the complete switch body can be mixed and integrally formed in the type 2 display group shown in “B” and “C” of FIG. Moreover, even if it is in the different specification of type 1 and type 2, at least the partial metal mold | die of a light guide part can be made common. In this manner, common components can be used for the display arrangement on a complex panel as shown in FIG. 4 or various display groups, thereby realizing an inexpensive electronic device.

  To summarize the above, in FIG. 4, in the electronic device of any one of the switch, the display, the switch-equipped display (the switch with the display), or a combination thereof, the components that are the main parts of the electronic device components are commonly used. It can be said that it was possible.

  In the embodiment of FIG. 4, a plurality of displays are sandwiched between one substrate and one panel. However, each of the plurality of displays is divided into a dedicated substrate and a plurality of independent panels. You may apply to the other Example of the structure held. In this case, the panel and the substrate as shown in FIG. 4 may be non-parallel or a parallel configuration. As a natural form of this embodiment, as shown in FIG. 6, the substrate comprises a box-shaped installation board composed of a small case body 71, and a casing together with a case body 72 corresponding to the panel 20 of FIG. May be included. The light guide 30S used in this embodiment may be exactly the same as the light guide 300 in FIG. 4 except that the base portion does not exist.

  In this embodiment, the light guide 30S is fitted on the upper surface of the concave case body 71 provided with the conductor patterns P8 and P9, and the shoulder body 34 is pressed down on the lower surface 23 of the case body 72 while the case body 71 is pressed. And the case body 72 are fitted together at the fitting surface 75 to constitute a display unit. Each case body 71, 72 is fixed with a screw (not shown).

  FIG. 6 shows a case where the height h1 of the case body 72 is low. When the case body 72 is high, the case body 72 looks like the light guides shown in “A” and “B” of FIG. That is, a common light guide can be used for both a display unit having a large case length D and a display unit having a small D. In the plurality of display units using the same light guide, screws (not shown) are screwed into screw holes 73 provided in the flange portion F of the case body 72 and screwed to a panel (not shown). When the display unit is fixed to the panel, the lead wire 711 protruding outward from the case body 71 is connected to a main board (not shown) by a cable or the like.

  In this embodiment, even when display units having different case lengths D are required, another unit is configured only by using a case body in which either the height h1 or h2 of the case body 72 or 71 is different. be able to. The display unit as shown in FIG. 6 is effective when a relatively small number of displays are required in various cases where the distance between the panel (upper case) and the substrate (lower case) is different. Further, in this embodiment, a boss for fixing the substrate of FIG. 4 becomes unnecessary.

As described above, each embodiment has been described. However, in the present invention, a plurality of indicators are not necessarily essential, and there are various advantages even with a single indicator configuration. Can be configured. That is, according to the type in which the light guide is sandwiched between the upper and lower cases and the type in which the light guide between the panel and the substrate is sandwiched, the interval has a molding error (such as a sink phenomenon in resin molding). Even so, there is an advantage that the error can be absorbed by the elasticity of the skirt portion, and also in this case, the inconvenience that the display brightness is different for each lot is eliminated.

  As described above, each of the embodiments has been described. In all the embodiments, the entire light guides 30, 300, 30C, and 30S are formed of an elastic material, and particularly the skirt portion 32 has elasticity. Since the light guide is compressed and held, the lower surface 23 of the light guide retainer and the shoulder 34 are always in close contact with each other, so that dust or the like does not enter the panel from the outside.

  In the present invention, the main body of the light guides 30, 300, 30C, and 30S has a step between the main body and the top portion as a locking portion when the light emitting display portion (top portion) protrudes from the panel hole and is fixed. Although the provided shoulder portion is provided, a taper forming portion having a steep angle may be used as the locking portion.

It is the perspective view which looked at the light guide used for the display apparatus of this invention from the top. It is the perspective view which looked at the same light guide from the bottom. It is a top view of the board | substrate (installation panel) which concerns on this invention. It is a sectional side view which shows the display apparatus of this invention. It is a top view which shows the other Example of this invention. It is a sectional side view which shows the further another Example of this invention. It is a sectional side view showing a prior art.
