Description

Push Button Switch Device of Vending Machine

(Technical field to which the invention belongs)

The present invention relates to a push button switch device of a vending machine.

(Conventional technology)

As a push button switch device of a vending machine, it is known, for example, described in Unexamined-Japanese-Patent No. 2-18229, Unexamined-Japanese-Patent No. 2-115223, etc., for example. These conventional ones include a support frame body detachably attached to the front panel of the vending machine, a circuit board provided on the front surface side of the support frame body, a switch unit and a light emitting unit provided on the front surface of the circuit board; And a waterproof cover covering the switch unit and the light emitting unit to be waterproof, a push button cover installed at the front side of the waterproof cover to press and press the waterproof cover, and installed at the inside of the waterproof cover. And a front member fixed to the support frame with a holding member for supporting the push button cover and a pressing operation hole of the push button cover.

The fixing member was formed in a reflector having a hole corresponding to the light emitting portion. The light emitted from the light emitting portion passing through the hole of the fixing member brightly illuminates part or all of the display portion provided between the push button cover or the waterproof cover to perform a predetermined light emission display.

In the pushbutton switch device of the conventional vending machine, since the reflecting body as the fixing member has a hole for passing light, its shape is complicated, and therefore, manufacturing cost is high.

The present invention aims to provide a push button switch device of a vending machine which is intended to reduce the manufacturing cost since the shape of the fixing member is simplified.

Further, in the conventional pushbutton switch device of the vending machine, since the reflector as the fixing member has only a hole for passing light, the pushbutton cover is bright at the center of the hole, It gradually became darker as the part corresponding to the inner corner. In other words, the light emitting state of the push button cover is uneven and unsightly, and in some cases, a part of the display portion becomes difficult to read.

The present invention can be achieved in view of the above circumstances, and an object of the present invention is to provide a push button switch device of a vending machine that can brighten the light emitting state of the push button cover, which makes it easy to read and that the display can be easily read. It is done.

(Means to solve the task)

In order to achieve the above object, the present invention has devised the following means. That is, a feature of the present invention includes a support frame body detachably attached to the front panel of the vending machine, a circuit board provided on the front surface side of the support frame body, and a front surface of the circuit board. An installed switch unit and a light emitting unit, a waterproof cover covering the switch unit and the light emitting unit to be waterproof, a push button cover installed at the front side of the waterproof cover to press and operate the waterproof cover, and inside the waterproof cover. A push button switch of a vending machine having a fixing member installed to support the waterproof cover between the push button cover and the front frame body fixed to the support frame with a push operation hole of the push button cover. In the apparatus, the fixing member is formed with a light transmitting portion for covering the light emitting portion and passing the light of the light emitting portion to the push button cover side. There is a point.

According to the configuration of the present invention, since the fixing member does not have a hole corresponding to the light emitting portion as in the prior art, the shape can be made simple and the manufacturing cost can be reduced.

By interposing the display panel between the waterproof cover and the fixing member, the sealing property of the display panel is improved as compared with that between the conventional push button cover and the waterproof cover.

In addition, since the light transmitting portion itself is formed on the display portion, there is no need to provide a conventional display panel, so that the number of parts can be reduced and the cost can be reduced.

In addition, the color of the display portion can be any color by coloring the light transmitting portion.

Furthermore, in the present invention, the light transmitting portion has a lens function for refracting light.

According to the configuration of the present invention, the light transmitting portion provided in the fixing member not only transmits the light from the light emitting portion but also refracts the light in a predetermined direction during the transmission. It is possible to make the display brighter, for example, to make the display easier to read or to brighten.

The light transmitting part may be formed to have a refractive index for extracting light parallel to the push button cover side.

In this way, the light emitting state widening in the plane shape can be obtained, so that even in the display portion having a large area to emit light, the corners of the display can be brightened constantly, and it is easy to read and stand out.

The light transmitting part may be formed to have a refractive index for extracting light focused on the push button cover side.

In this way, since a local light emission state can be obtained, individual light emitting areas can be brightened with respect to the display unit as if small light emitting areas such as letters and figures are arranged in a single or dotted manner. You can do it easily.

In this case, it is arbitrary whether the focus portion which can be made by focusing light is matched to the display portion or the push button cover, or to the viewer side (or the light emitting portion side).

In the related art, a state in which the central portion of the display portion is bright and its surroundings become dark is that the boundary between the bright portion and the dark portion is blurry, and a person who sees this feels a definite amount of light. Since only one desired point (i.e., the light emitting area) of the display portion can be emphasized and brightened to make the contrast between the surroundings clear, not only does it make the viewer feel uncomfortable, but rather the outline of the light emitting area. This becomes clear and has the advantage of being easy to understand.

The light transmitting portion may be formed to have a refractive index for extracting light diffused to the pushbutton cover side.

In this way, the light emitting state that is widened in the plane shape can be obtained, so that the display portion having a large area to emit light can be brightened to every corner of the display unit, and it is easy to read and stand out. In addition, this state can be similarly obtained even when the time for the push button cover is different (that is, the push button cover is viewed from a certain orientation). Therefore, the overall brightness is further increased, and the stand out is better.

In addition, in the present invention, a display panel is interposed between the waterproof cover and the push button cover, and the display panel is provided with two kinds of displays available for sale and sold out, and a plurality of the light emitting units are provided in correspondence with the respective displays. Each light emitting part is provided with an illumination degree individually according to the said display content.

In this way, when the illumination degree of the light emitting portion is changed in correspondence with each display, for example, the "sold out" display can be made bright and easy to see.

As shown in FIG.

The connector 12 is fixed to the rear surface of the support frame body 2 via a first seal member 13 made of a silicone rubber sheet or the like.

The threaded portion 14 is attached to the support frame body 2 in the vicinity of the connector 12. The threaded portion 14 has a projection 15 in which the rear portion of the support frame 2 integrally protrudes to the rear. A through hole 16 is provided in the projection 15, and the hole 16 is provided. The front face side of the side is a non-circular spot facing hole 17 such as a square or an ellipse. A metal cap nut 18 is fitted into the spot facing hole 17. On the rear side of the support frame body 2, a second seal member 19 fitted to the protrusion 15 is provided. The seal member 19 is formed as a seal packing made of silicone rubber or the like.

The waterproof cover 6 is made of silicone rubber or the like, has a predetermined elasticity, and has a light transmitting property. The waterproof cover 6 has an expansion portion 20 which expands in front of the switch operation portion 11 constituted from the switch portion 4, the light emitting portion 5, or the like with a predetermined space. This expansion part 20 is provided in succession by the number of said switch operation parts 11. The periphery 21 of the inflation portion 20 is configured to be in close contact with the front surface of the circuit board 3 to be waterproof.

And the pressing part 22 which presses and operates the said switch part 4 from the inner surface of the said expansion part 20 protrudes integrally in rod shape. The conductor is provided in the cross section of the rod-shaped pressing part 22, and it is comprised so that the circuit of the switch part 4 may short-circuit when the said conductor contacts the said switch part 4. As shown in FIG.

The fixing member 8 is installed inside the expansion part 20 of the waterproof cover 6. As shown in FIG. 2, the fixing member 8 includes a main wall 23 having an outer shape that fits into the internal shape of the expansion part 20, and a connecting wall connecting the central part of the main wall 23 ( 24 and a fitting portion 25 for fitting the rod-shaped pressing portion 22 formed on the connecting wall 24. Therefore, inside the fixing member 8, a pair of left and right spaces defined by the connecting wall 24 is formed. This space becomes a space which allows the light of the light emitting part 5 to pass. And this space can be blocked by the light transmission part 26 in the front surface side. This light-transmitting part 26 is shape | molded integrally with the said main wall 23 by a transparent body.

On the other hand, the circumferential wall 23 may be opaque in an opaque glass shape.

The display panel 27 is interposed between the light transmitting portion 26 and the waterproof cover 6. The display panel 27 displays "0" corresponding to the one light emitting unit 5 and "out of stock" corresponding to the other light emitting unit 5.

The display panel 27 may be interposed between the push button cover 7 and the waterproof cover 6.

The push button cover 7 is fitted to the front surface of the expansion part 20 of the waterproof cover 6. The push button cover 7 is formed of a hard transparent synthetic resin. The waterproof cover 6 is clamped by the inner surface of the push button cover 7 and the outer surface of the fixing member 8.

And the front frame body 10 which has the hole 9 through this push button cover 7 is fitted to the said support frame body 2 so that the front surface of the said support frame body 2 may be covered. . The front frame body 10 presses the periphery of the waterproof cover 6 in close contact with the circuit board 2.

A flange 28 is formed around the push button cover 7 to spread outward. The push button cover 7 is always held by the elastic force of the waterproof cover 6 so that the flange 28 is engaged with the periphery of the pressing operation hole 9 of the front frame body 10. The push button cover 7 is prevented from coming out from the hole 9.

On the other hand, by supporting the waterproof cover 6 with the pressing button cover 7 and the fixing member 8, the elastic force of the waterproof cover 6 is effectively exerted, the pressing operation of the pressing button cover 7 The elastic return to is surely performed.

In addition, the fixing member 8 regulates the amount of pressing of the pressing portion 22. That is, when the pressing portion 22 is pressed backward, the rear end surface of the fixing member 8 contacts the front surface of the circuit board 3 to regulate the amount of pressing of the pressing portion 22. At the same time, the tip of the pressing section 22 is configured to contact the switch section 4 with an appropriate contact pressure.

The pushbutton switch device unitized as described above is detachably attached to the front face of the front panel 1 of the vending machine. That is, the front panel 1 has a connector 12 of the pushbutton switch device. The fitting hole 29 is formed at the position corresponding to the cross-section, and the fixing hole 30 is formed at the position corresponding to the screw portion 14. Then, the connector 12 is inserted into the fitting hole 29. By pushing the projection 15 of the threaded portion 14 into the fixing hole 30 and screwing the bolt 31 to the nut 18 of the threaded portion 14, the push button switch device has a front face. It is fixed to the panel 1. At that time, since the sealing member 13 of the connector 12 blocks the fitting hole 29, and the sealing member 19 of the threaded portion 14 blocks the fixing hole 30, rain water is supported by the support frame. It is prevented from penetrating into the switch operating part 11 from the connector 12 or the threaded part 14 from the back side of the sieve 2.

According to the above configuration, since the fixing member 8 does not have a hole corresponding to the light emitting portion 5 as in the related art, the shape thereof can be made simple and the manufacturing cost can be reduced. Since the light emitting portion 5 is covered by the light transmitting portion 26, the phenomenon of fading by the light of the light emitting portion relative to the other member is prevented as compared with the conventional hole.

By interposing the display panel 27 between the waterproof cover 6 and the fixing member 8, the display panel is interposed between the conventional push button cover 7 and the waterproof cover 6, respectively. Sealability is improved.

3 shows another embodiment of the present invention, in which the fixing member 8 is integrally formed by two members of a transmissive portion 26 formed of a transparent body and a circumferential wall 23 formed of a non-transparent body. It is.

In the above-mentioned integral molding, various integral molding methods such as insert molding or molding by adhesion are employed. Further, the light transmitting portion 26 and the circumferential wall 23 may be integrally assembled by an insertion type or the like.

By using the light-transmitting portion 26 as a colored transparent body, the display panel 27 can be made into a simple gap to form letters or symbols.

In addition, the display panel 27 may be integrally formed on the circumferential wall 23 instead of the display panel 27.

In this way, the display panel 27 is combined with the fixing member 8, and the conventional display panel becomes unnecessary, so that the number of parts can be reduced.

4, 5, and 6 show the light-transmitting part 26 as the lens part 26a which light refracts, and the other structure is the same as that shown to the said FIGS.

That is, in the center portion of the light transmitting portion 26, only the side facing the light emitting portion 5 is expanded in a hemispherical shape, and the lens portion 26a having the flat surface on the side facing the push button cover 7 is provided. As shown in Fig. 7, the lens portion 26a has a refractive index capable of extracting light incident from the light emitting portion 5 as light parallel to the push button cover 7 side.

The distance between the lens portion 26a and the light emitting portion 5 is such that the pressing portion 22 is pressed backward and the outer peripheral rear end surface of the fixing member 8 is in contact with the front surface of the circuit board 3. Even in this case, the lens portion 26a is not in contact with the light emitting portion 5.

In addition, since the light from the light emitting portion 5 is taken out as the light parallel to the push button cover 7 side after being incident on the lens portion 26a of the light transmitting portion 26, the light emitting state widens in the plane shape. Can be obtained. Therefore, even if the area to emit light as described above is sold out, every corner of the display can be brightened, and it is easy to read and stand out.

This is the same degree of illumination as to the person who sees this as the difference in the number of characters and the display area between the display part of "0" and the display part of "sold out" provided on the display panel 27. It has the advantage of being given the concentration of.

In addition, conventionally, in a display portion having a large area to emit light such as "sold out", light hardly reaches about the left half of the "sold" letters and the right half of the "hawk" letters, so that these portions It was dark, especially under night lighting in front of the store, or in daylight, and had the drawback that the display content became difficult to understand. This shortcoming causes users who do not understand that the goods have not gone out even if the switch is operated, causing shaking or knocking of the vending machine, and as a result, malfunction of the security device, breakdown or damage of the vending machine, etc. It was connected to bring about the secondary bad effect to bring about.

Therefore, in the present invention, in addition to preventing the above secondary adverse effects, it can be said that it has a beneficial advantage.

8 shows another embodiment of the light transmitting section 26. The lens portion 26a provided in the light transmitting portion 26 is formed so as to expand in a hemispherical shape, as well as the side facing the light emitting portion 5 and the side facing the push button cover 7, respectively. The light incident on the 5) side has a refractive index that can be taken out as the light focused on the push button cover 7 side.

Light extracted to the push button cover 7 side is focused at the surface portion of the push button cover 7.

In this embodiment, since a local light emitting state can be obtained, individual light emitting areas can be brightened with respect to a display unit in which small light emitting areas such as letters and graphics are arranged in a single or dotted manner. It is easy to read.

9 shows another embodiment of the light transmitting portion 26. In the lens portion 26a provided in the light transmitting portion 26, the side facing the light emitting portion 5 becomes a flat surface, and the pushbutton cover ( Only the side facing 7) is formed to expand in a hemispherical shape, and as shown in FIG. 8, light incident from the light emitting portion 5 side can be taken out as light for focusing on the push button cover 7 side. It has a refractive index.

In this embodiment, however, the light extracted to the push button cover 7 is focused on a part closer to the viewer side than the push button cover 7. For this reason, compared with the thing shown in FIG. 8, a slightly wide area | region can be made bright.

10 shows another embodiment of the light transmitting section 26. As the light projecting portion 26, the side facing the light emitting portion 5 becomes a flat surface, and a plurality of the projections 26b protruding in a pyramid shape on the side facing the push button cover 7 are arranged in parallel and in parallel. Is installed. Therefore, the light incident from the light emitting portion 5 side has a refractive index that can be taken out as the light diffusely reflected to the push button cover 7 side.

In this embodiment as well, as shown in Figs. 4 and 7, the light emitting state widening in a planar shape can be obtained, but not only that, but the light emitting state may have different views on the push button cover 7. At the same time (i.e., even when the push button cover 7 is viewed from a certain orientation), there is an advantage that the same can be obtained. Therefore, there is an advantage that the overall illuminance is further improved, and that the display of the display panel 27 is easier to read regardless of the position and height at which the user of the vending machine stands.

11 shows another embodiment of the present invention and improves the sealing performance of the waterproof cover 6.

That is, in the support frame body 2, the circumferential groove 30 is recessed so as to surround the circuit board 3, and the protrusion 21 'formed on the periphery 21 of the waterproof cover 6 is formed as described above. It fits in the circumferential groove 30, and the improvement of waterproof performance is aimed at. The front frame body 10 for pressing the waterproof cover 6 against the support frame body 2 and the support frame body 2 are welded at high frequency in the contact portion 31.

In this embodiment, the display panel 21 is interposed between the waterproof cover 6 and the push button cover 7.

As shown in FIG. 12, it is another aspect of this invention and made the illumination degree of the light emission part 5 variable.

That is, the light emitting part 5 corresponding to "0" indicating the marketability of the display panel 27 consists of one light source 32, and the light emitting part 5 corresponding to "sold out" includes two light sources ( 33, 34). The display of "sold out" is made brighter than "0".

Each of the light sources 32, 33, 34 is suitably connected in series, but even in the case of parallel wiring, the applied voltage may be adjusted, or the material of the semiconductor used for the light sources 32, 33, 34 may be changed. The illumination degree as the light emitting part 5 can be added.

In the case of parallel wiring, even if one light source does not emit light due to breakage, the other light source continues to emit light, so there is an advantage that emergency light until the repair period is maintained. In addition, in the case of the LED light emitting element, the light intensity decreases due to aging, but the state of the art which hardly becomes a disconnected state is regarded as the state of the art, so that the two light sources 33 and 34 of the light emitting part 5 are connected in series. Even when aging due to long-term use, the two light sources 33 and 34 of the " sold out " are rarely deteriorated at the same time, and the sold out display function continues even if the luminance of the sold out is reduced.

The light emission colors of the light sources 32, 33, and 34 of the light emitting portion 5 are changed to emit light in their synthetic colors as a whole, or may be emitted in multiple colors as it is, and further to the viewer. Can be promoted.

The display panel 27 may have a transmissive portion of two characters or more, such as "sold out" or "stop sales", and in this case, the number of light sources of the light emitting portion 5 may be increased.

Unlike the above embodiment, only one light source of each of the light emitting units 5 and 5 corresponding to the display panel 27 can be configured to change the luminous intensity of the left and right light sources. In order to enhance the light intensity of the light source, the material of the semiconductor used for the light source may be changed, the number of layers or the thickness of the junction may be changed, or the current value may be changed.

In each of the light emitting units 5 and 5, a light emitting diode is not limited to the light source, but a neon bulb, an incandescent bulb, a fluorescent tube, or the like can be used.

In addition, this invention is not limited to what was indicated by the said embodiment. In addition, the aspect of each embodiment can also be combined.

For example, in the light-transmitting section 26, the surface of the lens section 26a may be diamond cut, or the projections 26b may have a hemispherical shape, irregularities formed by each convex shape, or the like. .

The lens portion 26a type, the plurality of projection portion 26b types, the plate type, and the like may be appropriately used for the display portion of "0" and the display portion "out of stock" provided on the display panel 27. .

It is also possible to provide a plurality of lens sections 26a corresponding to each letter of "sold out" with respect to one light transmitting section 26.

According to the present invention, since the fixing member does not have a hole corresponding to the light emitting portion as in the prior art, the shape can be made simple and the manufacturing cost can be reduced.

By interposing the display panel between the waterproof cover and the fixing member, the sealability of the display panel is improved as compared with that between the conventional push button cover and the waterproof cover.

In addition, since the light transmitting portion itself is formed on the display portion, there is no need to provide a conventional display panel, so that the number of parts and the cost can be reduced.

In addition, the color of the display portion can be any color by coloring the light transmitting portion.

In addition, according to the present invention, the light transmitting portion provided in the fixing member transmits the light from the light emitting portion while refracting in a predetermined direction. Part, or part you want to brighten).

In the light transmitting portion, when light is taken out parallel to the pushbutton cover side, a light emitting state widening in the plane shape can be obtained, so that even a display portion having a large area to emit light can be brightened to every corner. It is easy to read and stands out.

When the light is focused on the pushbutton cover side, the light emitting part can obtain a local light emission state. Therefore, the display part may be configured such that a small light emitting area such as a character or a figure is arranged in a single or dotted manner. In contrast, the individual light emitting regions can be made bright and easy to read.

In the light transmitting portion, when light diffused to the push button cover side is diffused, a light emitting state that is widened in a plane shape can be obtained, so that every corner of the light emitting part can be brightly lit even in a wide display portion. It is easy to read and also stands out. In addition, this state can be obtained in the same manner even when the time for the push button cover is varied (that is, even if the push button cover is viewed from any direction). Therefore, there is an advantage that the overall illuminance is further increased, and that the display of the display panel is easier to read regardless of the position or height at which the user of the vending machine stands.

In addition, by varying the illumination degree of the plurality of light transmitting parts, it is possible to eliminate the invisible display.
