  By the way, also in the field of portable terminals, it is extremely useful if the switch has an illuminated configuration, since the visibility can be greatly improved. However, due to the nature of mobile terminals, there are situations where the number of parts and space restrictions are large, and there is a problem that it is difficult to realize an illuminated configuration. For example, when a projector element is arranged on a substrate, an operation button is arranged at a predetermined distance from the substrate, and the operation button is illuminated by the projector element, the height of the projector element mounted on the substrate is increased. In addition, it is necessary to consider the pressing stroke of the operation button, and it is necessary to secure a certain distance from the substrate to the operation button. As a result, there is a problem that the thickness or width of the entire portable terminal is increased, and downsizing of the entire apparatus is hindered.

And the periphery of the diffusion surface is surrounded by a flat surface or a convex surface.

  According to a fifth aspect of the present invention, in the portable terminal operation switch according to any one of the first to fourth aspects, the fixed contact includes a first electrode having a comb pattern and a second electrode having a comb pattern. The adjacent component part in which the first electrode and the second electrode are adjacent to each other is arranged in two positions across the hole part, and the movable contact is Both adjacent components can be contacted, and in at least one of the two adjacent components, the first electrode and the second electrode come into contact with the movable contact to turn on. It is characterized by becoming.

  According to a sixth aspect of the present invention, in the portable terminal operation switch according to any one of the first to fifth aspects, the tip of the light projecting element is disposed between the one surface and the other surface. It is characterized by being.

  According to the first aspect of the present invention, the light projecting element is mounted on the opposite surface side (the other surface side) of the fixed contact, and is disposed in the hole formed in the substrate, and the light emitted from the light projecting element is light-derived. The operation button is made to enter through the unit. Therefore, it is possible to suitably realize a configuration capable of causing the operation button to emit light and to effectively project the projection amount of the light projecting element to the operation button side as compared with the case where the light projecting element is mounted on the surface of the fixed contact side of the substrate. It becomes easy to arrange the operation button and the board close to each other. As a result, it is possible to effectively reduce the size of the operation switch for the mobile terminal, and thus contribute to the size reduction of the entire mobile terminal.

  According to the second aspect of the present invention, the light deriving portion includes a deriving hole for deriving emitted light, and the operation button is formed with a convex portion that fits into the deriving hole.

For example, even when the pressure on the operation button is shifted to any one of the adjacent component portions, good conduction is achieved between the one adjacent component portion and the movable contact.

  In the invention of claim 6, since the front end portion of the light projecting element is disposed between the one surface and the other surface, the front end portion of the light projecting element does not protrude toward the operation button (that is, the front end is a hole). The operation button and the substrate can be easily arranged closer to each other, and as a result, the apparatus can be further reduced in size.

[First embodiment]
Hereinafter, a first embodiment in which an operation switch for a portable terminal according to the present invention is embodied will be described with reference to the drawings.
FIG. 1 is a cross-sectional view schematically showing a switch for mobile terminal according to the first embodiment. Note that FIG. 1 shows the vicinity of the position AA in FIG. FIG. 2 is an enlarged view showing an enlarged configuration of operation buttons and button holding members used in the portable terminal switch of the first embodiment. FIG. 3 is a back view of the configuration of FIG. 2 viewed from the light projecting element side. FIG. 4 is an enlarged view showing a state of the fixed terminal arranged on the substrate. FIG. 5 is a plan view schematically illustrating a substrate used for the portable terminal switch of the first embodiment. FIG. 6 is a plan view showing an example of a mobile terminal using the mobile terminal switch of the first embodiment.

  A mobile terminal operation switch 10 shown in FIG. 1 constitutes a part of the mobile terminal 1 (see FIG. 6), and includes a push-type operation button 20 and a button holding member 30 that holds the operation button 20. And a unit in which the operation buttons 20 and the button holding member 30 are coupled to each other is fixed to a substrate 40 disposed in the case 2 (FIG. 6) of the portable terminal 1.

  The operation button 20 is made of a light transmissive resin material or the like, and is disposed at a position overlapping the light projecting element 50 in the thickness direction of the substrate 40. As shown in FIGS. 1 and 6, the operation button 20 is arranged so as to be exposed to the outside of the mobile terminal 1 (specifically, exposed to the outside through a hole 2 a formed in the case 2). There is a configuration in which light from the light projecting element 50 is emitted to the outside through the operation button 20. In addition, in FIG. 1, the position where case 2 should be arrange | positioned is virtually shown with the dashed-two dotted line.

  The button holding member 30 is fixed to the substrate surface 40a (the substrate surface 40a corresponds to an example of “one surface”) of the substrate 40 by an adhesive medium such as an adhesive or a connecting member such as a screw. As described above, a lead-out hole 33 (lead-out hole 33 corresponds to an example of a “light lead-out part”) that guides the light emitted from the light projecting element 50 to the operation button 20 side, and elastic deformation that supports the operation button 20 The flexible part 35 is provided. The “flexible part 35” refers to the entire part capable of being displaced by the flexural deformation with respect to the non-displaceable annular fixed part 39 fixed to the substrate 40. As shown in FIGS. An annular thin portion 35a connected to 39, and a button support portion 35b that is arranged inside the thin portion 35a and interlocks according to the elastic deformation of the thin portion 35a.

  Further, as shown in FIG. 1, a part of the bending portion 35 is disposed between a fixed contact 41 (described later) and the operation button 20, and a portion (that is, a button support portion 35b) in which the bending portion 35 is interposed. ), The movable contact 31 is arranged to face the fixed contact 41. As shown in FIG. 3, the movable contact 31 is configured in an annular and layered manner on the back surface side (the surface side facing the substrate 40) of the bending portion 35.

  The fixed contact 41 is a contact fixed to the substrate surface 40a side of the substrate 40 as shown in FIGS. 1, 4 and 5, and as shown in FIG. 4, the first electrode 42 having a comb pattern, And a second electrode 43 having a comb pattern. Furthermore, the adjacent component parts 47 and 48 in which the first electrode 42 and the second electrode 43 are adjacent to each other are arranged to be opposed to each other at two positions across the hole 45, and the movable contact 31 is Both adjacent components 47 and 48 can be contacted. In the configuration of the present embodiment, the first electrode 42 and the second electrode 43 are in contact with the movable contact 31 in at least one of the two adjacent component portions 47 and 48, whereby the first electrode 42 and the second electrode 43 are in contact with each other. The electrode 42 and the second electrode 43 are electrically connected via the movable contact 31 and are turned on. In FIG. 4, the position when the movable contact 31 contacts the fixed contact 41 is virtually indicated by a two-dot chain line.

  In this configuration, when the operation button 20 is pressed from the state of FIG. 2, the operation button 20 tends to be displaced to one side in the thickness direction of the substrate 40 (in the direction of the arrow D1), and the thin portion 35a is elastically deformed accordingly. . Then, in conjunction with this, the button support portion 35b is displaced in the pressing direction of the operation button 20 (that is, the direction of the arrow D1), and the movable contact 31 approaches and contacts the fixed contact 41. On the other hand, when the pressing of the operation button 20 is released, the thin portion 35b tries to return to the natural state (the state shown in FIG. 2), so that the button holding portion 35b is in the direction opposite to the pressing direction (the direction of the arrow D2). Pushed up. Thereby, the movable contact 31 is separated from the fixed contact 41, the conduction between the first electrode 42 and the second electrode 43 is cut off, and the switch is turned off.

  The light projecting element 50 described above is composed of a light emitting element such as an LED, and is mounted on the substrate surface 40b side of the substrate 40 (the substrate surface 40b corresponds to an example of the “other surface”) as shown in FIG. Thus, the light emitted from the light projecting element 50 enters the operation button 20. More specifically, a hole 45 that penetrates the substrate 40 in the thickness direction is formed in the substrate 40, and is formed on the substrate surface 40b (that is, the substrate surface opposite to the substrate surface 40a on the fixed contact 41 side). A part of the light projecting element 50 to be mounted is accommodated in the hole 45 and emits light to the operation button 20 side. Thus, the emitted light from the light projecting element 50 accommodated in the hole 45 is incident on the operation button 20 through the lead-out hole 33, and light is emitted from the operation button 20 to the outside.

  The light projecting element 50 disposed in the hole 45 has a tip portion disposed between the substrate surface 40a and the substrate surface 40b, and the tip portion is completely accommodated in the hole 45, and from the substrate surface 40a. The tip of the light projecting element 50 is configured not to protrude. In FIG. 1, a specific configuration for mounting the light projecting element 50 on the substrate surface 40 b side is omitted, but the light projecting element 50 is held on the substrate surface 40 b, and a part thereof is in the hole 45. Any mounting configuration may be used as long as the configuration is arranged.

  Further, in the present embodiment, as shown in FIGS. 1 to 3, the lead-out hole 33 formed in the button holding member 30 is configured to be fitted to the convex portion 21 formed in the operation button 20. The convex portion 21 is a light incident portion (that is, a portion where outgoing light is incident). The convex portion 21 is disposed at a position overlapping the light projecting element 50 in the thickness direction of the substrate 40, and more specifically, the convex portion 21 is configured in a columnar shape having a diameter larger than the diameter of the hole 45. The light emitting element 50 having a size that can be accommodated in the hole 45 is disposed opposite to the light emitting element 50. Further, the convex portion 21 of the operation button 20 (that is, the light incident portion where the emitted light is incident) has a convex condensing surface 21a for condensing the emitted light, and is denoted by reference numeral L1 in FIG. As conceptually shown, the light emitted from the light projecting element 50 is condensed by the condensing surface 21a, and the brightness of a predetermined portion of the operation button 20 is locally enhanced.

  The portable terminal operation switch 10 configured as described above is used by being incorporated into a part of the portable terminal 1 shown in FIG. Note that the portable terminal operation switch 10 shown in FIGS. 1 to 5 is an example of a switch at one place of the portable terminal 1, but it goes without saying that the same configuration can be used as a switch at another place. is there. The portable terminal 1 according to the present embodiment is configured as an optical information reading device such as a barcode reader or a two-dimensional code reader, and the portable terminal operation switch 10 includes such an optical information reader. It is configured as an illumination type switch of the information reading device.

As described above, in the portable terminal operation switch 10 of the present embodiment, the light projecting element 50 is mounted on the opposite surface side (the other surface side) of the fixed contact 41, and in the hole 45 formed in the substrate 40. The light emitted from the light projecting element 50 is made to enter the operation button 20 through the lead-out hole 33. Therefore, it is possible to suitably realize a configuration capable of causing the operation button 20 to emit light, and to the operation button 20 side of the light projecting element 50 compared to the case where the light projecting element is mounted on the surface of the substrate 40 on the fixed contact 41 side. The amount of protrusion can be suppressed, and the operation button 20 and the substrate 40 can be more easily arranged at a distance. As a result, it is possible to effectively reduce the size of the operation switch for the mobile terminal, and thus contribute to the size reduction of the entire mobile terminal.
In addition, since the operation button 20 and the button holding member 30 that connects the operation button 20 to the substrate 40 are configured as separate members, an appropriate material excellent in light transmittance can be selected for the operation button 20. About the button holding member 30, it becomes easy to select the appropriate material which can be elastically deformed.

  Further, the portable terminal operation switch 10 is composed of a lead-out hole 33 through which the light lead-out part leads out the emitted light, and the operation button 20 is formed with a convex part 21 that fits into the lead-out hole 33. Therefore, the operation button 20 and the button holding member 30 can be satisfactorily coupled without requiring a large space, and the light toward the operation button 20 can be obtained by using the convex portion 21 for fitting as a light incident portion. Is also preferably derived.

  Moreover, since the light incident part of the operation button 20 has the convex condensing surface 21a which condenses the emitted light, a part with a large amount of transmitted light is generated in the operation button 20, and the operation button 20 is specified. The visibility of a part can be improved effectively.

In addition, in at least one of the adjacent components 47 and 48, the first electrode 42 and the second electrode 43 are turned on when they come into contact with the movable contact 31. Therefore, poor contact between the movable contact 31 and the fixed contact 41 is less likely to occur. For example, even when the pressure on the operation button 20 is shifted to one of the adjacent component portions, the one adjacent component portion and the movable contact 31 can be electrically connected to each other.
Further, the adjacent placement portions 47 and 48 are provided at two opposing positions, and the fixed contact 41 is formed in a long shape so that no adjacent placement portions are provided on both sides of the hole 45 in the lateral direction (short direction of the fixed contact 41). It is composed. Therefore, the width of the fixed contact 41 can be reduced, and the installation space for the fixed contact 41 can be effectively reduced. Thereby, advantageous effects such as downsizing of the substrate and an increase in mounting space for other components can be obtained.

  In addition, since the front end portion of the light projecting element 50 is disposed between the substrate surface 40a and the substrate surface 40b, the front end portion of the light projecting element 50 does not protrude toward the operation button 20 (that is, the front end is a hole). The operation button 20 and the substrate 40 are more easily arranged closer to each other, and as a result, the entire apparatus can be further miniaturized.

[Second Embodiment]
Next, a second embodiment will be described. FIG. 7 is a cross-sectional view schematically showing a switch for a portable terminal according to the second embodiment, and FIG. 8 is a back view of the configuration of the operation button and the button holding member of FIG. 7 viewed from the light projecting element side. is there. Note that the portable terminal switch 110 of the second embodiment differs from the first embodiment only in the configuration of the operation buttons, and is otherwise the same as the first embodiment. Therefore, the configuration of different parts will be described with emphasis, and the configuration of the same parts will be denoted by the same reference numerals as those of the first embodiment, and the first embodiment will be referred to as appropriate, and detailed description thereof will be omitted.

  As shown in FIG. 7, in the portable terminal switch 110 of the present embodiment, an operation button 120 that is different from the operation button 20 (see FIG. 1) of the first embodiment only in the shape of the convex portion is used. The convex portion 121 in the operation button 120 is a light incident portion into which outgoing light enters, and includes a concave diffusion surface 121a for diffusing the outgoing light, and the periphery of the diffusion surface 121a is defined by the convex surface 121b. The structure is surrounded. As shown in FIG. 8, the region on the center side of the convex portion 121 (region in the two-dot chain line A1) is a concave diffusion surface 121a, and the outer region (region outside the two-dot chain line A1) is convex. It is set as the surface 121b. The convex surface 121b has a configuration in which the convex portion continues in an annular shape.

  In the configuration of the present embodiment, the convex portion 121 (that is, the light incident portion) of the operation button 120 is provided with the concave diffusion surface 121a for diffusing the light emitted from the light projecting element 50. It can diffuse entirely within 120. Further, since the periphery of the diffusing surface 121a is annularly surrounded by the convex surface 121b, the outgoing light entering the periphery of the diffusing surface is suppressed from being diffused, so that the side (with respect to the side from which light should be derived) Leakage in the horizontal direction is suppressed. Therefore, as conceptually shown in L2 of FIG. 7, when the operation button 120 emits light, the emitted light is efficiently used so as to cover the entire operation button 120.

  In the portable terminal operation switch 110 of the present embodiment, the light projecting element 50 is mounted on the opposite surface side (the other surface side) of the fixed contact 41 and formed on the substrate 40 as in the first embodiment. Arranged in the hole 45, the light emitted from the light projecting element 50 is made to enter the operation button 120 through the lead-out hole 33. Therefore, a configuration capable of causing the operation button 120 to emit light can be suitably realized, and the light projecting element 50 is closer to the operation button 120 than the case where the light projecting element is mounted on the surface of the substrate 40 on the fixed contact 41 side. The amount of protrusion can be suppressed, and the operation button 120 and the substrate 40 can be more easily arranged at a distance. As a result, it is possible to effectively reduce the size of the operation switch for the mobile terminal, and thus contribute to the size reduction of the entire mobile terminal.

  In the portable terminal operation switch 110 according to the present embodiment, the light lead-out portion includes the lead-out hole 33 through which the emitted light is led out. On the other hand, the operation button 120 has a convex portion 121 that fits into the lead-out hole 33. ing. Therefore, the operation button 120 and the button holding member 30 can be satisfactorily coupled without requiring a large space, and the convex portion 121 related to the fitting is used as the light incident portion, so that the light toward the operation button 120 side can be obtained. Derivation is also preferably performed.

  Also in this embodiment, as in the first embodiment, the adjacent components 47 and 48 in which the first electrode 42 and the second electrode 43 are adjacent to each other are located at two positions with the hole 45 interposed therebetween. The movable contacts 31 are arranged so as to face each other and can contact both adjacent components 47 and 48 (the configuration is the same as in FIGS. 4 and 5). In at least one of the adjacent constituent parts 47 and 48, the first electrode 42 and the second electrode 43 are turned on when they come into contact with the movable contact 31. Therefore, poor contact between the movable contact 31 and the fixed contact 41 is less likely to occur. For example, even when the pressure on the operation button 20 is shifted to one of the adjacent component parts, good conduction is achieved between one adjacent component part and the movable contact 31.

  Also in the present embodiment, since the tip of the light projecting element 50 is disposed between the substrate surface 40a and the substrate surface 40b, the tip of the light projecting element 50 does not protrude toward the operation button 120 ( That is, the front end is completely accommodated in the hole 45), and the operation buttons 120 and the substrate 40 can be easily arranged closer to each other, and the apparatus can be further miniaturized.

  In the second embodiment, the example in which the periphery of the diffusion surface 121a is surrounded by the convex surface 121b is shown, but the periphery of the diffusion surface 121a is surrounded by a flat surface (for example, a flat surface parallel to the substrate surface 40a). Also good.

  In the above-described embodiment, an example in which a convex portion that fits into the lead-out hole is formed in the operation button is shown, but such a convex portion may be omitted. That is, a configuration in which the lead-out hole and the operation button are not fitted may be used.
