Description

  The present invention relates to an electronic apparatus including a push switch device with a lighting function.

  For example, in the push-type switch device described in Patent Document 1, an operation button having a display surface is housed in a switch case, and the display surface is moved through the operation button by light emitted from a light source provided on the back side of the switch case. It is the structure which permeate | transmits illumination from the back side. The display surface side of the operation button is fitted from the back side of the panel into a hole formed in the design panel of the electronic device. The switch case is fixed to the back side of the panel.

  In the push-type switch device, when light emitted from the light source leaks out of the operation button, it leaks to the front side of the panel from a gap existing between the operation button, the switch case, and the panel hole. Therefore, in the push-type switch device described in Patent Document 1, the shading rib formed on the back side in the switch case and located inside the back side end portion of the operation button allows the operation button to move from the inside of the operation button. It was designed to shield the light from leaking out to the surroundings.

  Since the conventional push-type switch device is configured as described above, a switch case in which a light-shielding rib is formed in addition to the panel and operation buttons is required, and there is a problem that the number of parts increases. Increasing the number of parts increases costs and complicates the assembly process.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to reduce the number of parts compared to the conventional structure while preventing light leakage from the operation switch to the surroundings.

  The electronic device according to the present invention is movable in a direction in which a switch installed on the back side of the panel is operated in a state in which the fitting hole is formed and the fitting hole is fitted from the back side of the panel. Operation buttons, a light transmission part that is formed on the front of the operation buttons and transmits the light emitted from the light source installed on the back side of the panel and irradiates the front side of the panel, and the back side of the side of the operation buttons is the front side A stepped portion having a shape protruding outward, and a light-shielding rib that protrudes from the back surface of the panel and has a tip portion facing the stepped portion and covering the front side of the side surface of the operation button.

  According to the present invention, the stepped portion where the back side of the side surface of the operation button protrudes outward from the front side, and the light shielding material which covers the front side of the side surface of the operation button, protruding from the back surface of the panel and facing the stepped portion. Since the rib is provided, light leakage from the gap between the operation button and the fitting hole can be prevented. Further, since the light shielding rib is provided on the panel, the switch case which has been conventionally required is not required, and the number of parts can be reduced.

Embodiment 1 FIG.
FIG. 1 is an external perspective view showing an example of an electronic apparatus 1 according to Embodiment 1 of the present invention. In the first embodiment, a disk playback device is shown as an example of the electronic apparatus 1. In the electronic apparatus 1 which is a disk reproducing device, a front panel of a housing in which a disk player or the like is accommodated is a design panel 2. The panel 2 is provided with a disc insertion slot 3, a display 4, an operation button 20, and the like.
In the first embodiment, as an example of the operation button 20, a power button that switches on and off the power of the electronic device 1 is shown. When the operation button 20 which is a power button is pressed by the user, the switch 6 (not shown) installed on the back side of the operation button 20 is operated to turn on or off the power of the electronic device 1.

  FIG. 2 is a cross-sectional view of the electronic device 1 cut along the line A-A ′ of FIG. 1. FIG. 3 is an external perspective view showing an example of the operation button 20. 4A is a front view of the operation button 20, FIG. 4B is a right side view, FIG. 4C is a rear view, and FIG. 4D is a bottom view.

  The panel 2 is configured by a member that does not transmit light. A substrate 5 is installed on the back side of the panel 2. A switch 6 and a light source 7 are mounted on a portion of the substrate 5 facing the panel 2 and covered with the operation button 20. The light source 7 may be anything that emits light, such as an LED (Light Emitting Diode).

A light transmitting portion 21 that transmits light emitted from the light source 7 installed on the back side of the panel 2 and irradiates the front side is formed on the front surface that is the operation surface of the operation button 20. In the illustrated example, the light transmitting portion 21 has a shape of a mark meaning a power button, but the shape may be anything such as a character or a symbol.
The operation button 20 is formed using a member that transmits light, and the light transmitting portion 21 is configured by painting a portion except the light transmitting portion 21 with a paint that does not transmit light. Alternatively, the operation button 20 is formed by two-color molding of a resin that does not transmit light and a resin that transmits light, and the light transmitting portion 21 is configured by a resin that transmits light, and the light transmitting portion 21 is formed by a resin that does not transmit light. The part except for is configured.

Of the side surfaces of the operation buttons 20, the front side near the panel 2 is referred to as a side front portion 22, and the back side near the substrate 5, the switch 6, and the light source 7 is referred to as a side rear portion 23.
A step 24 is formed by the side rear portion 23 projecting outward from the side front portion 22. One or more linear guide ribs 25 that guide the movement of the operation button 20 are formed on the side rear portion 23. Further, the side rear portion 23 is formed with one or more drop prevention claws 26 for preventing the operation buttons 20 from dropping from the panel 2. Further, a pusher 27 for pushing the switch 6 is formed inside the operation button 20.

  The panel 2 has a fitting hole 10 into which the operation button 20 is fitted. The fitting hole 10 is formed larger than the operation surface so that a gap is formed between the operation hole 20 and the front surface that is the operation surface. Therefore, the operation button 20 fitted in the fitting hole 10 can move in the direction in which the switch 6 is operated.

  On the back surface of the panel 2, a light shielding rib 11 is formed that protrudes toward the substrate 5 and covers the front side 22 of the operation button 20. The light shielding rib 11 has, for example, a rectangular cylindrical shape, and can cover the front side 22 of the operation button 20 over the entire circumference. Further, the tip of the light shielding rib 11 faces the stepped portion 24 of the operation button 20.

  In addition, on the back surface of the panel 2, an accommodating portion 12 that protrudes toward the substrate 5 and accommodates the operation button 20 is formed. The accommodating portion 12 is formed with a linear guide rail 13 into which the guide rib 25 of the operation button 20 is movably fitted. The guide rail 13 may be a slit penetrating the accommodating portion 12 or a recess. Further, the accommodating portion 12 is formed with a linear dropout prevention hole 14 into which the dropout prevention claw 26 of the operation button 20 is movably fitted. The accommodating part 12 may have any shape, and it is sufficient that the accommodating part 12 is at least at a position where the guide rail 13 and the drop-off preventing hole 14 are formed.

  The operation button 20 is fitted into the fitting hole 10 from the back side of the panel 2 and is accommodated in the accommodating portion 12. When the operation button 20 is fitted into the fitting hole 10, the guide rib 25 is fitted into the guide rail 13 and the drop prevention claw 26 is fitted into the drop prevention hole 14. The dropout prevention claw 26 fits into the dropout prevention hole 14, thereby preventing the operation button 20 from falling out of the housing portion 12.

When the operation button 20 in the normal position shown in FIG. 2 is pressed by the user, the pusher 27 pushes the switch 6 as the operation button 20 moves. When the user stops pressing, the operation button 20 is urged to the front side of the panel 2 by the reaction force of the switch 6 and returns to the normal position shown in FIG. Note that the operation button 20 may be biased to the front side of the panel 2 by a biasing member such as a spring (not shown) installed on the back side of the panel 2 instead of the reaction force of the switch 6. Good.
When the operation button 20 moves, the guide rib 25 slides in the guide rail 13, whereby the movement of the operation button 20 is guided and rattling is suppressed. In addition, when forming the light transmissive part 21 by coating, since it will become difficult to slide if the guide rib 25 is painted, it is desirable that the guide rib 25 is not painted.
Further, when the user presses the operation button 20 strongly, the drop prevention claw 26 is hooked on the edge of the drop prevention hole 14 to function as a stopper, and excessive movement of the operation button 20 is restricted.

The light emitted from the light source 7 leaks to the outside of the operation button 20 from the gap between the operation button 20 and the substrate 5 or from the side of the operation button 20 such as the guide rib 25 that is not painted. In the first embodiment, since the tip end portion of the light shielding rib 11 and the stepped portion 24 of the operation button 20 face each other and there is almost no gap, light leaking outside the operation button 20 is blocked. Therefore, it is possible to prevent light leaking outside the operation button 20 from leaking from the gap between the operation button 20 and the fitting hole 10 to the front side of the panel 2.
Further, the higher the height at which the rear side portion 23 protrudes from the front side portion 22, that is, the higher the height B of the stepped portion 24 shown in FIG. 2, the longer the light path from the light source 7 to the fitting hole 10. Therefore, the effect of preventing light leakage is improved.

  As described above, the electronic device 1 according to the first embodiment has the panel 2 in which the fitting hole 10 is formed and the back side of the panel 2 in a state of being fitted into the fitting hole 10 from the back side of the panel 2. An operation button 20 that is movable in the direction in which the installed switch 6 is operated, and a front side of the panel 2 that transmits light emitted from a light source 7 that is formed on the front side of the operation button 20 and that is installed on the back side of the panel 2. The light transmitting portion 21 that irradiates the surface, the stepped portion 24 having a shape in which the side rear portion 23 of the operation button 20 protrudes outward from the front side portion 22, and the front end portion of the operation button 20 that protrudes from the back of the panel 2 faces the stepped portion 24. The light shielding rib 11 covers the front side portion 22 of the button 20. By providing the step portion 24 on the operation button 20 and providing the light shielding rib 11 on the back surface of the panel 2, light leakage from the gap between the operation button 20 and the fitting hole 10 can be prevented. Further, since the light shielding rib 11 is provided on the panel 2, the switch case which has been conventionally required becomes unnecessary, and the number of parts can be reduced. By reducing the number of parts, the cost can be reduced and the assembly process can be simplified.

  In addition, the electronic device 1 according to the first embodiment protrudes from the back surface of the panel 2 and includes a housing portion 12 that houses the operation button 20, a guide rib 25 that is formed on the operation button 20 and guides the movement of the operation button 20, The guide rail 25 is formed in the accommodating portion 12 and the guide rib 25 is fitted to be movable in the moving direction of the operation button 20. Thereby, the rattling at the time of the movement of the operation button 20 can be controlled.

  In the illustrated example, the guide rib 25 is formed on the operation button 20 and the guide rail 13 is formed on the housing portion 12. On the contrary, the guide rail 13 is formed on the operation button 20 and the guide rib 25 is formed on the housing portion 12. May be.

  In addition, the electronic device 1 according to the first embodiment is formed on the operation button 20 and is formed on the dropout prevention claw 26 for preventing the dropout of the operation button 20 from the storage portion 12 and the dropout prevention. The claw 26 includes a dropout prevention hole 14 that is movably fitted in the moving direction of the operation button 20. Thereby, dropping of the operation button 20 after fitting in the fitting hole 10 can be prevented. In addition, a stopper function when the operation button 20 is strongly pressed can be realized.

  In the illustrated example, the operation button 20 is provided with the drop-off prevention claw 26 and the storage portion 12 is formed with the drop-out prevention hole 14. On the contrary, the operation button 20 is formed with the drop-out prevention hole 14 and stored. The part 12 may be provided with a drop preventing claw 26. In the illustrated example, from the viewpoint of mold feasibility, a drop prevention claw 26 is formed in the operation button 20, and a drop prevention hole 14 is formed in the housing portion 12.

Embodiment 2. FIG.
FIG. 5 is a cross-sectional view of electronic device 1 according to Embodiment 2 of the present invention cut along line AA ′ of FIG. FIG. 6 is an external perspective view showing an example of the operation button 20a of the second embodiment. 7A is a front view of the operation button 20a, FIG. 7B is a right side view, and FIG. 7C is a bottom view. Since the structure on the back side of the operation button 20a is the same as the structure shown in the back view of FIG. 4C, illustration is omitted here.
5 to 7, the same or corresponding parts as those in FIGS. 1 to 4 are denoted by the same reference numerals and description thereof is omitted.

  In the electronic device 1 according to the second embodiment, the operation button 20 a includes a wall portion 28 that protrudes from the step portion 24 toward the panel 2. The wall portion 28 and the side surface front portion 22 sandwich the light shielding rib 11. The wall portion 28 is formed using a member that transmits light, and is painted with a paint that does not transmit light. Alternatively, when the operation button 20a is formed by two-color molding, the wall portion 28 is made of a resin that does not transmit light.

  The light emitted from the light source 7 leaks to the outside of the operation button 20a from the gap between the operation button 20a and the substrate 5 or from the side surface of the operation button 20a such as the guide rib 25 that is not painted. In the second embodiment, since the wall portion 28 blocks the gap between the portions where the light shielding rib 11 and the step portion 24 face each other, the light leaked to the outside of the operation button 20a is more reliably blocked. Therefore, it is possible to more reliably prevent light leaking outside the operation button 20a from leaking from the gap between the operation button 20a and the fitting hole 10 to the front side of the panel 2.

In the illustrated example, the wall portion 28 and the side rear portion 23 have the same height and are flush with each other. May be raised. As the height of the side rear portion 23 increases, the light path from the light source 7 to the fitting hole 10 becomes longer, so that the effect of preventing light leakage is improved. The height of the side rear portion 23 referred to here refers to the right and left direction in FIG.
Moreover, since the light path from the light source 7 to the fitting hole 10 becomes longer as the height C of the wall portion 28 protruding from the step portion 24 toward the panel 2 increases, the effect of preventing light leakage is improved. Here, the height C of the wall portion 28 refers to the vertical direction of the drawing in FIG.
Moreover, in the example of illustration, although the wall part 28 is formed over the perimeter of the level | step-difference part 24, the part may be interrupted.

The guide rib 25 may be formed from the side rear portion 23 to the wall portion 28. By increasing the overall length of the guide rib 25, it is possible to further regulate the rattling when the operation button 20a is moved.
The formation position of the drop-off preventing claw 26 may be the side rear portion 23 or the wall portion 28.

Since the operation buttons 20 and 20a according to the first and second embodiments described above require the side surface front portion 22 to be smaller than the side surface rear portion 23 in order to form the stepped portion 24, the operation surface exposed from the panel 2 is used. This is particularly useful for operation buttons with small specification conditions.
Further, if a conventional light shielding switch case is provided on the back side of the operation buttons 20 and 20a, the illumination range becomes small. Therefore, if the light transmitting portion 21 is set large with respect to the operation surface, illumination is established. May not. On the other hand, in Embodiments 1 and 2, since the entire inside of the operation buttons 20 and 20a is irradiated, even if the light transmission portion 21 is large with respect to the operation surface, the establishment of illumination is not affected. Therefore, it is particularly useful for an operation button having a specification condition in which the light transmission portion 21 is set larger than the operation surface.
Furthermore, since the step portion 24 is formed on the entire circumference of the side surfaces of the operation buttons 20 and 20a and is covered with the light-shielding rib 11, a design in which the operation buttons are present alone or the operation buttons are separated from each other. Suitable for design.

  In the present invention, within the scope of the invention, any combination of each embodiment, any component of each embodiment can be modified, or any component of each embodiment can be omitted.
