< first embodiment >
A product selection device (product selection device) 11 and a product selection means (product selection means) 10 according to a first embodiment of the present invention will be described with reference to fig. 2 to 5.
As shown in fig. 2, the product selection unit 10 of the first embodiment includes 6 product selection devices 11, and an elongated main board 12 that supports the product selection devices 11 from below. As shown in fig. 3, the product selection device 11 of the first embodiment includes a sample holding portion 112, a sensor substrate 111, a light guide plate LGP, and a product sample S, and they are stacked in this order. As shown in fig. 2 and 3, the product sample S is positioned in front of the paper surface of the product selection means 10, and the sample holding portion 112 is positioned behind the paper surface. In the following description, the side of the product selection device 11 where the product sample S is located (the side facing the user) is referred to as the front side of the product selection unit 10 and the product selection device 11, and the side where the sample holding portion 112 is located is referred to as the rear side of the product selection unit 10 and the product selection device 11.
The commodity selection device 11 is provided with 6 commodity selection devices arranged in parallel along the length direction of the main substrate 12 on the upper surface of the main substrate 12. As will be described later, each product selection device 11 is detachable from the main board 12.
The sensor substrate 111 of the product selection device 11 according to the first embodiment is a rectangular plate that is long in the vertical direction and short in the width direction. In the central portion of the front surface of the sensor substrate 111, the sensor electrodes SE are formed in a circuit pattern. The sensor electrode SE is connected to a first connection terminal CT1, which will be described later, by a wiring not shown.
Below the sensor electrode SE, 4 light sources LS arranged in parallel in the width direction are provided. The 4 light sources LS are all color-variable LEDs, and are side-emitting LEDs provided so that their optical axes extend in the longitudinal direction (vertical direction) of the sensor substrate 111 within a plane parallel to the sensor substrate 111. That is, the 4 light sources LS are mounted on the sensor substrate 111 so as to emit light upward. The 4 light sources LS are connected to a first connection terminal CT1, which will be described later, by wiring lines, not shown.
A first connection terminal CT1 is provided at the lower end (lower surface) of the sensor substrate 111. The first connection terminal CT1 is a terminal for connecting the wirings from the sensor electrodes SE and the 4 light sources LS to the wirings on the main board 12, and may be any connection terminal such as a pin type or a card type.
The sample holding portion 112 on the rear side of the sensor substrate 111 includes a back plate 112a which is a rectangular plate that is long in the vertical direction and short in the width direction, and a pair of side plates 112b that stand forward from both end portions in the width direction of the back plate 112 a.
The pair of side plates 112b have ribs 112t at front end portions thereof, respectively. The ribs 112t are plate-like members projecting inward from the front end of the side plate 112b, and extend substantially parallel to the back plate 112 a.
The pair of side plates 112b each have a stopper 112s near the front end of the inner surface (the surface facing the other side plate 112 b). The stoppers 112s are plate-like members projecting inward from the inner surfaces of the side plates 112b, and extend perpendicularly to the back plate 112a and the side plates 112 b. A gap G is formed between the stopper 112s and the back plate 112 a.
Engaging pieces E1 are formed at the lower end portions of the pair of side plates 112 b. The engaging piece E1 is a portion used when the product selection device 11 is mounted on the main board 12, and is configured to be engageable with an engaging hole E2 (described later) of the main board 12.
The rear surface of the sensor substrate 111 is attached to the front surface of the back plate 112a of the sample holding portion 112. At this time, the vicinity of the lower end of the sensor substrate 111 extends downward through the gap G and is disposed below the stopper 112 s. That is, the 4 light sources LS and the first connection terminal CT1 are disposed below the stopper 112 s. In addition, the 4 light sources LS are arranged between the pair of stoppers 112s in the width direction so as not to shield the light generated by the 4 light sources LS from the stoppers 112 s.
The light guide plate LGP is a planar illumination member having a light incident surface and a planar light emitting surface, and uniformly emits light incident from the light incident surface from the light emitting surface. The light guide plate LGP is made of a light-transmitting resin such as an acrylic resin or a polycarbonate resin, and has a plate portion PT as shown in fig. 4 a.
A rectangular incident surface IS for receiving light into the plate PT IS formed on a side surface of the plate PT. One of the surfaces connected to the long sides of incident surface IS a reflection surface (facing surface) RS that reflects light that IS incident from incident surface IS into plate section PT and guided in plate section PT, and the other surface (surface facing reflection surface RS) IS an emission surface ES that emits light guided in plate section PT.
A plurality of convex portions c are formed on the reflection surface RS of the plate PT. The convex portions c are each a substantially hemispherical protrusion protruding outward from the reflection surface RS, and are arranged over the entire reflection surface RS. The density of the convex portions c formed on the reflection surface RS IS low in the vicinity of the incidence surface IS and becomes higher as it IS farther from the incidence surface IS. Thus, the light incident from the incident surface IS can be uniformly emitted from the emission surface ES.
The light guide plate LGP is supported from below by the stopper 112s and is disposed in the sample holding portion 112 in a state where the reflection surface RS faces the front surface of the sensor substrate 111. The incident surface IS of the light guide plate LGP IS disposed to face the 4 light sources LS of the sensor substrate 111.
The product sample S is a flat plate-like (two-dimensional) sample in which a photograph, an illustration, and the like of a product (for example, a cigarette or a cake) are printed on one surface of a rectangular light-transmitting sheet. The commodity sample S is arranged in front of the light guide plate LGP, and is supported by the light guide plate LGP, the side plate 112b of the sample holding portion 112, the rib 112t, and the stopper 112S.
As shown in fig. 2, the main control unit MC, the light source driving unit LD, and the sensor circuit unit SCU are formed on one surface (upper surface) of the main board 12.
The main control unit MC controls the overall operation of the product selection unit 10, and is connected to the vending machine main body side control unit VMC (fig. 6). The main control unit MC is also connected to the light source driving unit LD and the sensor circuit unit SCU through unillustrated wiring.
The light source driving unit LD is a circuit that controls the operation of the light source LS of the sensor substrate 111. The light source driving unit LD is connected to the main control unit MC and a second connection terminal CT2 (described later) via unillustrated wirings.
The sensor circuit unit SCU includes 6 sensor circuits SC, which form a capacitance sensor together with the sensor electrodes SE of the sensor substrate 111. The sensor circuit unit SCU is connected to the main control unit MC and the second connection terminal CT2 by unillustrated wiring lines.
As shown in fig. 5, a second connection terminal CT2 and an engagement hole E2 are provided in an area a1 corresponding to one commodity selection device 11 on one surface (upper surface) of the main board 12. There are 6 regions a1 in the one surface of the primary base plate 12 having the above-described configuration juxtaposed in the longitudinal direction.
The second connection terminal CT2 is a terminal for connecting the wiring from the light source driving unit LD and the sensor circuit unit SCU to the wiring on the sensor substrate 111, and may be any connection terminal.
The engagement holes E2 are provided in a pair on one surface of the main board 12, at a position forward of the second connection terminals CT2, and spaced apart in the longitudinal direction. The engaging holes E2 are formed as rectangular through holes that are long in the front-rear direction in the present embodiment, and can be engaged with the engaging pieces E1 of the sample holding portion 112.
The commodity selection device 11 is detachable from the main board 12. The commodity selection device 11 can be mounted on the main board 12 by connecting the first connection terminal CT1 of the sensor board 111 to the second connection terminal CT2 of the main board 12 and engaging the engaging piece E1 of the sample holding portion 112 with the engaging hole E2 of the main board 12.
In a state where the product selection device 11 and the main board 12 are connected, the sensor electrode SE of the sensor board 111 and the sensor circuit SC of the main board 12 are connected via the first connection terminal CT1 and the second connection terminal CT2, thereby forming a capacitance sensor. The light source LS of the sensor board 111 is connected to the light source driving unit LD of the main board 12 via the first connection terminal CT1 and the second connection terminal CT 2. Fig. 6 shows a block diagram of the product selection unit 10 in a state where the product selection device 11 and the main board 12 are connected.
In the present specification, the portion from which the product sample S is removed from the product selection device 11 of the first embodiment is referred to as the sensor device SD1 (fig. 3) of the first embodiment, and the portion from which the product sample S is removed from the product selection unit 10 of the first embodiment is referred to as the sensor unit SU1 (fig. 2) of the first embodiment.
Next, a method of using and an operation of the product selection means 10 according to the first embodiment will be described.
When the product selection unit 10 is used in the vending machine VM, first, the main board 12 is disposed in the storage portion D1 of the display portion D. The main board 12 can be arranged with an arbitrary number of layers in the vertical direction. When the horizontal dimension of the storage portion D1 is large, a plurality of main boards 12 may be arranged in parallel in the horizontal direction, or a main board 12 including 6 or more areas a1 may be used.
Next, a product sample S on which a photograph, an illustration, or the like showing the product sold by the vending machine VM is printed is prepared and held by the sample holding portion 112 of the sensor device SD 1. As described above, the commodity sample S is stably held in front of the sensor electrode SE and the light guide plate LG by the light guide plate LGP and the side plate 112b, the rib 112t, and the stopper 112S of the sample holding portion 112.
Next, the sensor unit SU1 (i.e., the product selection device 11) holding the product sample S is attached to the main board 12. In this case, the commodity selection device 11 may be mounted on all of the area a1 of the main board 12, or the commodity selection device 11 may be mounted on only a part of the area a 1. By installing the product selection device 11 in all the areas a1 of the main board 12, a wider variety of products can be sold. By installing the article selection device 11 only in the area a1 of a part of the main board 12, it is possible to effectively use the area a1 where the article selection device 11 is not installed to implement decoration for promotion (POP or the like).
Finally, a price display panel PP corresponding to the disposed commodity sample S is attached to the transparent plate D2 of the display portion D. This completes the installation of the product selection means 10 in the display section D. The price indication plate PP is attached to the transparent plate D2 before the product selection unit 10 is placed in the storage portion D1.
In a state where coins are not inserted into the coin insertion port IC of the vending machine VM, the product selection unit 10 is in a standby state under the control of the vending machine main body side main control unit VMC. In the standby state, the light source LS of the article selection device 11 lights a white light. Light from the light source LS enters the plate portion PT through the entrance surface IS of the plate portion PT of the light guide plate LGP, IS reflected by the convex portion c formed on the reflection surface RS of the plate portion PT and the front surface of the sensor substrate 111, and IS emitted from the emission surface ES. The light emitted from the exit surface ES illuminates the product sample S from behind. The light source LS may also be extinguished in a standby state when the corresponding commodity is sold out.
When the user inserts coins into the coin inlet IC of the vending machine VM, the sensor circuit unit SCU, which has detected this via the vending machine main body side control unit VMC and the main control unit MC, causes a current to flow through the sensor electrode SE of the sensor substrate 111. Thereby, an electric field penetrating the light guide plate LGP and the commercial sample S is formed between the electrodes of the sensor electrodes SE of the substrate 111. At this time, the lines of electric force between the sensor electrodes SE spread to the front of the commercial product sample S.
Next, the user selects a desired product, that is, selects any one of the plurality of product selection devices 11 of the product selection means 10, and approaches a product photograph or the like printed on the product sample S of the product selection device 11 with his hand. At this time, when the hand of the user approaches the product sample S of the product selection device 11 to some extent, the amount of change in the electric field (electric line of force) formed between the sensor electrodes SE provided in the selected product selection device 11 reaches the first reference value, and the capacitance of the capacitance sensor formed by the sensor electrodes SE and the corresponding sensor circuits SC reaches the first reference value.
When the main control unit MC detects that the capacitance of any one of the plurality of capacitance sensors reaches the first reference value, it controls the light source driving unit LD to change the light source LS of the product selection device 11 including the capacitance sensor from white light emission to blue light emission. The user can visually recognize the operation of the article selection device 11 and select an article desired to be purchased.
In the case where the user wishes to purchase the commodity selected by the user, the user further approaches the commodity sample S with his/her hand. When the hand of the user comes closer to the product sample S of the product selection device 11, the amount of change in the electric field (electric line of force) formed between the sensor electrodes SE provided in the product selection device 11 reaches the second reference value, and the capacitance of the capacitance sensor formed by the sensor electrodes SE and the corresponding sensor circuits SC reaches the second reference value.
When the main control unit MC detects that the capacitance of any one of the plurality of capacitance sensors reaches the second reference value, the light source driving unit LD is controlled to increase the light amount of the blue light emitting light source LS of the product selection device 11 including the capacitance sensor for a predetermined time. The user can visually recognize the operation of the article selection device 11 and purchase an article desired to be purchased.
The main control unit MC also transports the product corresponding to the selected product selection device 11 to the product output port IO via the vending machine main body side control unit VMC.
The effects of the sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 of the present embodiment are summarized as follows.
The sensor device SD1 and the sensor unit SU1 of the first embodiment have sensor electrodes SE and a light guide plate LGP arranged to cover the sensor electrodes SE. Therefore, when the sensor device SD1 and the sensor unit SU1 according to the first embodiment are disposed behind the commercial sample S, the sensor electrode SE of the capacitive sensor is disposed behind the commercial sample S, and the user can move the capacitive sensor by approaching the commercial sample S with a hand. According to the sensor device SD1 and the sensor unit SU1 of the first embodiment, since selection and purchase of a product can be performed by an intuitive operation of extending a hand to a product desired to be purchased, it is possible to prevent a user from erroneously selecting and purchasing a product.
In addition, according to the sensor device SD1, the sensor unit SU1, the commodity selection device 11, and the commodity selection unit 10 of the first embodiment, since the sensor electrode SE of the capacitance sensor is arranged behind the commodity sample S, only the price display plate PP needs to be attached to the transparent plate D2 of the display portion D, and there is no need to attach a commodity selection button. Therefore, according to the sensor device SD1 and the like of the first embodiment, the display portion D can be reduced in size (particularly, in the vertical direction).
Further, according to the sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 of the first embodiment, since the light guide plate LDP can be disposed behind the product sample S and the product sample S can be illuminated from behind, part or all of the other illumination devices for illuminating the product sample S can be removed from the display portion D. Therefore, according to the sensor device SD1 and the like of the first embodiment, the display portion D can be compactly sized.
The sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 according to the first embodiment are configured to show the user that the capacitive sensor is operating by changing the color and brightness of light emitted from the light source LS in accordance with the operation of the sensor electrode SE. Thus, the user can visually recognize that the capacitive sensor is operated, and thus, an erroneous operation such as a secondary pressing operation can be prevented.
The sensor unit SU1 and the commodity selection unit 10 of the first embodiment are configured by the main board 12 and the sensor device SD1 or the commodity selection device 11 that is detachable from the main board 12, and the sensor device SD1 or the commodity selection device 11 can be freely arranged in the display unit D2 only by detaching the sensor device SD1 or the commodity selection device 11 from the main board 12 provided in the vending machine VM. That is, the sensor unit SU1 and the product selection unit 10 according to the first embodiment can lay out the product samples S with a high degree of freedom.
When the sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 according to the first embodiment are used, it is not necessary to dispose a product selection button penetrating the transparent plate D2 in the transparent plate D2 of the display unit D of the vending machine VM. Therefore, the intrusion of external dust and moisture into the housing portion D1 can be prevented. Further, since the outer surface of the transparent plate D2 can be made flat, cleaning of the outer surface of the transparent plate D2 is facilitated.
In the sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 of the first embodiment, the light source LS and the light guide plate LGP are arranged in a relatively fixed state in the sensor device SD1 or the product selection device 11. Therefore, when the sensor device SD1 and the product selection device 11 are mounted on the main board 12, it is not necessary to perform positioning between the light source LS and the light guide plate LGP.
In the sensor device SD1 and the like according to the first embodiment, the number of light sources LS provided on the sensor substrate 111 and the direction of the optical axis can be changed as appropriate. For example, the one or more light sources LS may be disposed above the sensor electrode SE of the sensor substrate 111 and irradiate light downward. The one or more light sources LS may be provided on one side in the width direction of the sensor electrode SE of the sensor substrate 111 and emit light to the other side in the width direction. In these cases, the light source LS and the incident surface IS of the light guide plate LGP are arranged to face each other while appropriately adjusting the shape and arrangement of the light guide plate LGP.
< second embodiment >
Next, a product selection device (product selection device) 21 and a product selection means (product selection means) 20 according to a second embodiment of the present invention will be described with reference to fig. 2, 5, and 7.
The product selection unit 20 of the second embodiment is different in configuration from the product selection device 11 of the product selection unit 10 of the first embodiment in the product selection device 21, but is otherwise the same as the product selection unit 10 of the first embodiment. That is, the main substrate 22 of the merchandise selection unit 20 of the second embodiment has the same configuration as the main substrate 12 of the merchandise selection unit 10 of the first embodiment (fig. 5).
The product selection device 21 of the second embodiment has a structure in which the sensor substrate 211, the sample holding portion 212, and the product sample S are superposed on each other.
The sensor substrate 211 of the product selection device 21 is a rectangular plate that is vertically long and is short in the width direction, similarly to the sensor substrate 111 of the product selection device 11. The sensor electrode SE is formed in a circuit pattern in the center of the front surface of the sensor substrate 211, 6 light sources LS are provided around the sensor electrode SE, and a first connection terminal CT1 is provided at the lower end (lower surface) of the sensor substrate 211. The sensor electrode SE and the light source LS are connected to the first connection terminal CT1 by unillustrated wirings.
The 6 light sources LS are arranged in parallel 3 in the vertical direction on both sides in the width direction of the sensor electrode SE. The 6 light sources LS are all variable color LEDs, and their optical axes are orthogonal to the surface of the sensor substrate 211, and are top surface emission LEDs provided so as to extend forward of the substrate 211. That is, the light source LS is attached to the substrate 211 so as to irradiate the commodity sample S (from the rear to the front) with light from the substrate 211.
The sample holding portion 212 in front of the sensor substrate 211 includes a back plate 212a which is a rectangular plate that is long in the vertical direction and short in the width direction, and a pair of side plates 212b that stand forward from both ends in the width direction of the back plate 212 a.
Near both ends in the width direction of the back plate 212a, 3 through holes 212h are provided, which are aligned in the vertical direction. These 6 through holes 212h in total are provided at positions on the back plate 212a, which overlap the 6 light sources LS when the back plate 212a is mounted on the sensor substrate 211. The back plate 212a is a light guide plate for guiding light from the light source LS to the product sample S through the through hole 212 h. Further, a translucent plate material having a milky white color or the like may be disposed in the through hole 212h to diffuse the light from the light source LS. In this case, the semi-permeable plate is also one of the light guide plates. In this specification, a material which transmits light partially is referred to as a semi-permeable material.
The pair of side plates 212b have ribs 212t at front end portions thereof, respectively. The ribs 212t are plate-like members projecting inward from the front end of the side plate 212b, and extend substantially parallel to the back plate 212 a.
The pair of side plates 212b each have a stopper 212s on an inner surface (a surface opposite to the other side plate 212 b). The stoppers 212s are plate-like members projecting inward from the inner surfaces of the side plates 212b, and extend perpendicularly to the back plate 212a and the side plates 212 b.
Engaging pieces E1 are formed at the lower end portions of the pair of side plates 212 b. The engaging piece E1 is a portion used when the product selection device 21 is attached to the main board 22, and is configured to be engageable with the engaging hole E2 of the main board 22.
The rear surface of the back plate 212a of the sample holding portion 212 is attached to the front surface of the sensor substrate 211. At this time, the 6 light sources LS provided on the sensor substrate 211 are accommodated in the 6 through holes 212h provided on the back plate 212a of the sample holding portion 212, respectively. That is, the 6 light sources LS are arranged such that their optical axes extend perpendicularly to the back plate 212 through the through hole 212h of the back plate 212a of the sample holder 212.
The commercial sample S has the same configuration as the commercial sample S of the first embodiment. The product sample S is arranged in front of the back plate 212a of the sample holding portion 212, and is supported by the back plate 212a, the side plate 212b, the rib 212t, and the stopper 212S of the sample holding portion 212.
In the present specification, the portion from which the product sample S is removed from the product selection device 21 of the second embodiment is referred to as a sensor device SD2 (fig. 7) of the second embodiment, and the portion from which the product sample S is removed from the product selection unit 20 of the second embodiment is referred to as a sensor unit SU2 (fig. 2) of the second embodiment.
The sensor device SD2, the sensor unit SU2, the product selection device 21, and the product selection unit 20 of the second embodiment can be used and operated in the same manner as the sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 of the first embodiment, but the method of irradiating the product sample S with the light source LS is different. In the sensor device SD2, the sensor unit SU2, the product selection device 21, and the product selection unit 20 according to the second embodiment, the light from the light source LS illuminates the product sample S from behind via the through hole 212h of the sample holder 212.
The sensor device SD2, the sensor unit SU2, the product selection device 21, and the product selection unit 20 according to the second embodiment can provide the same effects as those of the sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 according to the first embodiment. Further, since the sensor device SD2, the sensor unit SU2, the merchandise selection device 21, and the merchandise selection unit 20 of the second embodiment do not have the internally reflective light guide plate LGP as used in the first embodiment, they can be manufactured inexpensively and easily.
< third embodiment >
Next, a product selection device (product selection device) 31 and a product selection means (product selection means) 30 according to a third embodiment of the present invention will be described with reference to fig. 2, 8, and 9.
The arrangement of the main light sources LS is different for the article selection unit 30 of the third embodiment from the article selection unit 10 of the first embodiment. Specifically, the 4 light sources LS provided to the article selection device 11 in the article selection unit 10 of the first embodiment are provided to the upper surface of the main substrate 32 in the article selection unit 30 of the third embodiment.
As shown in fig. 8, the product selection device 31 of the third embodiment has a structure in which a sensor substrate 311, a sample holding portion 312, a light guide plate LGP, and a product sample S are stacked in this order.
The sensor substrate 311 of the product selection device 31 is a rectangular plate that is long in the vertical direction and short in the width direction, similarly to the sensor substrate 111 of the product selection device 11. The sensor electrode SE is formed in a circuit pattern in the center of the front surface of the sensor substrate 311, and a first connection terminal CT1 is provided at the lower end (lower surface) of the sensor substrate 311. The sensor electrode SE and the first connection terminal CT1 are connected by a wiring not shown.
The sample holding portion 312 in front of the sensor substrate 311 includes a back plate 312a which is a rectangular plate that is long in the vertical direction and short in the width direction, and a pair of side plates 312b that stand forward from both ends in the width direction of the back plate 312 a.
The pair of side plates 312b have ribs 312t at the front end portions, respectively. The ribs 312t are plate-like members protruding inward from the front end of the side plate 312b, and extend substantially parallel to the back plate 312 a.
The pair of side plates 312b have stoppers 312s on inner surfaces (surfaces opposed to the other side plate 312 b), respectively. The stoppers 312s are plate-like members projecting inward from the vicinity of the front end of the inner surface of the side plate 312b, and extend perpendicularly to the back plate 312a and the side plate 312 b. A gap G is formed between the stopper 312s and the back plate 312 a.
Engaging pieces E1 are formed at the lower end portions of the pair of side plates 312 b. The engaging piece E1 is a portion used when the product selection device 31 is attached to the main board 32, and is configured to be engageable with the engaging hole E2 of the main board 32.
The rear surface of the back plate 312a of the sample holding portion 312 is attached to the front surface of the sensor substrate 311.
The light guide plate LGP is a rectangular plate having the same configuration as the light guide plate LGP of the first embodiment, but has a larger dimension in the length direction (up-down direction) than the light guide plate LGP of the first embodiment. The light guide plate LGP of the merchandise selection device 31 of the third embodiment is mounted on and held by the front surface of the back plate 312a of the sample holding portion 312. Unlike the sample holding portion 112 of the product selection device 11 of the first embodiment, the sample holding portion 312 of the third embodiment IS configured such that the lower surface (the incident surface IS) of the light guide plate LGP IS not supported by the stopper 312s and IS disposed below the stopper 312s through the gap G. More specifically, the position thereof is near the front of the first connection terminal CT 1.
The commercial sample S has the same configuration as the commercial sample S of the first embodiment. The commodity sample S is arranged in front of the light guide plate LGP, and is supported by the light guide plate LGP and the side plate 312b, the rib 312t, and the stopper 312S of the sample holding portion 312.
The main substrate 32 of the third embodiment is the same as the main substrate 12 of the first embodiment except that 4 light sources LS are provided in the region a 1.
As shown in fig. 9, the second connection terminal CT2 is provided at the center of the area a1 of the main board 32 according to the third embodiment, and a pair of engagement holes E2 are provided at positions apart from each other in the longitudinal direction in front of the second connection terminal CT 2. The second connection terminal CT2 has the same configuration as the second connection terminal CT2 of the first embodiment, and the pair of engagement holes E2 has the same configuration as the engagement holes E2 of the first embodiment.
Between the pair of engaging holes E2, 4 light sources LS are arranged in parallel at equal intervals in the longitudinal direction. The 4 light sources LS are all color-variable LEDs whose optical axes are orthogonal to the surface of the main substrate 32, and are top-surface-emission LEDs provided so as to extend upward of the main substrate 32. That is, the light source LS is mounted on the main substrate 32 so as to emit light upward from the main substrate 32.
The commodity selection device 31 is detachable from the main board 32. The commodity selection device 31 can be attached to the main board 32 by connecting the first connection terminal CT1 of the sensor board 311 to the second connection terminal CT2 of the main board 32 and engaging the engaging piece E1 of the sample holding portion 312 with the engaging hole E2 of the main board 32. When the product selection device 31 IS mounted on the main board 32, the incident surface IS of the light guide plate LGP of the product selection device 31 IS disposed to face the 4 light sources LS of the main board 32.
In the present specification, the portion from which the product sample S is removed from the product selection device 31 of the third embodiment is referred to as the sensor device SD3 (fig. 8) of the third embodiment, and the portion from which the product sample S is removed from the product selection unit 30 of the third embodiment is referred to as the sensor unit SU3 (fig. 2) of the third embodiment.
The sensor device SD3, the sensor unit SU3, the product selection device 31, and the product selection unit 30 of the third embodiment can also be used in the same manner as the sensor device SD1, the sensor unit SU1, the product selection device 11, and the product selection unit 10 of the first embodiment, and operate in the same manner.
The sensor device SD3, the sensor unit SU3, the article selection device 31, and the article selection unit 30 of the third embodiment can provide the same effects as those of the sensor device SD1, the sensor unit SU1, the article selection device 11, and the article selection unit 10 of the first embodiment.
In the first to third embodiments described above, the following modifications may be adopted.
In the product selection devices 11, 21, 31 and the product selection means 10, 20, 30 of the first, second, and third embodiments described above, the price of the product corresponding to the product sample S can be displayed on the product sample S. By using such a product sample S, the price display sheet PP is not required, and thus the plurality of layers of product selection units 10, 20, and 30 can be arranged more compactly in the display section D of the vending machine VM. Further, since the price of the product desired to be purchased is displayed integrally with the product sample, the user can visually recognize the price of the product desired to be purchased at a glance. This can prevent erroneous recognition of the price of the product desired to be purchased.
In the first, second, and third embodiments described above, the description has been given of the case where the product selection devices 11, 21, and 31 and the product selection units 10, 20, and 30 are applied to the vending machine VM, but the present invention is not limited thereto. The article selection devices 11, 21, 31 and the article selection units 10, 20, 30 may be used for devices that display articles (gifts, prizes, etc.) other than articles of merchandise, or may be used for game machines and the like. The applications of the product selection devices 11, 21, 31 and the product selection means 10, 20, 30 are arbitrary. In the present specification, expressions such as the article selection device and the article selection means are used as a generic concept of the article selection devices 11, 21, and 31 and the article selection means 10, 20, and 30. The "item" includes, but is not limited to, a "product" and includes items other than a product such as a rental product or a gift, which is provided for free.
In the first, second, and third embodiments described above, the number of the product selection devices 11, 21, and 31, the sensor devices included in the product selection units 10, 20, and 30, and the number of the product selection devices are arbitrary, and the number of the areas a1 formed in the main boards 12, 22, and 32 is also arbitrary. The main substrates 12, 22, 32 may be housed in respective cases. In this case, the engagement hole E2 may be provided in the case.
In the first, second, and third embodiments, the electric field (electric flux lines) formed by the sensor electrodes penetrates the light guide plate LGP and the commercial sample S to reach the front of the commercial sample S, but the present invention is not limited thereto. The electric field formed by the sensor electrode does not need to reach the front of the commercial sample S as long as the electric field formed by the sensor electrode changes by the user' S hand approaching or touching the commercial sample S.
In the sensor devices SD2, SD3 and commodity selection devices 21, 31 of the second and third embodiments described above, the sample holders 212, 312 may further include portions that cover the sensor substrates 211, 311 from behind. In this case, the back plate 312a of the sample holding portion 312 may be omitted.
In the sensor devices SD1, SD2, SD3 and the commodity selection devices 11, 21, 31 of the first, second, and third embodiments described above, the sensor circuit SC may be formed on the sensor substrates 111, 211, 311. In the sensor devices SD1, SD2, SD3 and commodity selection devices 11, 21, 31 of the first, second, and third embodiments, the sensor substrates 111, 211, 311 and the sample holders 112, 212, 312 may be separate bodies. In this case, for example, the sensor substrates 111, 211, 311 are attached to the main substrates 12, 22, 32 via the first connection terminal CT1 and the second connection terminal CT2, and the sample holding portions 112, 212, 312 are attached to the main substrates 12, 22, 32 via the engagement piece E1 and the engagement hole E2.
In the sensor devices SD1, SD2, SD3 and the commodity selection devices 11, 21, 31 of the first, second, and third embodiments described above, the commodity sample S is not limited to a plate-like structure on which two-dimensional printing is performed, and may be a three-dimensional structure, for example, a cylindrical shape in the case of a sample of canned beverages, or a shape obtained by dividing a plastic bottle into halves in the longitudinal direction in the case of a sample of plastic bottle beverages. Other commercial samples may be of various shapes and sizes. Therefore, the light guide plate LGP or the sample-holding portion 112, 212, 312 in the sensor devices SD1, SD2, SD3 and the commodity-selecting devices 11, 21, 31 of the first, second, and third embodiments may be in various shapes and sizes corresponding to the shape and size of the commodity sample S used. The sensor substrates 111, 211, and 311 may be detachable from any of the sample holders 112, 212, and 312 or the light guide plate LGP having various shapes and sizes, and may be used together with commercial samples S or light guide plates LGP having various shapes and sizes.
In the sensor devices SD1, SD2, SD3 and the commodity selection devices 11, 21, 31 of the first, second, and third embodiments, the sample holding portions 112, 212, 312 may not have the engaging piece E1. In this case, the engaging hole E2 of the corresponding main board 12, 22, 32 is also not required.
In the sensor device SD2 and the product selection device 21 of the second embodiment, the back plate 212a of the sample holder 212 may be formed of a semi-permeable plate material having a milky white color or the like without having a through hole. Such a semi-permeable plate is also one of the light guide plates of the present invention.
The sensor devices SD1, SD2, SD3 and the commodity selection devices 11, 21, 31 of the first, second, and third embodiments described above may not have sample holders 112, 212, 312, respectively. In this case, for example, a label or the like for displaying the sample can be attached to the emission surface ES side of the light guide plate LGP. Alternatively, the main substrates 12, 22, and 32 may hold the product samples S, or the light guide plate itself may be printed with the product samples S. The product sample S may be formed by using a hologram printing technique, or by performing retroreflective printing or light storing printing on a part thereof.
In the first and third embodiments, as shown in fig. 4(b), a prism array in which prisms p are continuous may be formed on the reflection surface RS of the plate portion PT of the light guide plate LGP instead of the plurality of convex portions c. Even with such a prism p (prism array), the light of the plate PT can be guided to the emission surface ES side. The prisms p may be formed to have a lower density in the vicinity of the incident surface IS and a higher density as they are farther from the incident surface IS, as in the case of the convex portions c. Thus, the light incident from the incident surface IS can be uniformly emitted from the emission surface. In the present specification, the convex portions c and the prisms p formed on the reflection surface RS of the plate PT are collectively referred to as "optical convex portions". In the light guide plate LGP, a large surface can be uniformly illuminated by adjusting the distribution of the optical protrusions formed on the reflection surface RS of the plate portion PT.
In the light guide plate LGP, the optical protrusions on the reflection surface RS may be formed at a uniform density over the entire area of the reflection surface RS. When the light-emitting surface ES of the plate PT is small, the light-emitting surface ES can be uniformly emitted even with such a configuration.
The light guide plate LGP may have a reflective film (not shown) disposed to face the reflective surface RS so as to cover the entire area of the reflective surface RS. Such a reflective film functions to return light leaking from the reflective surface RS of the plate PT into the plate PT. The reflective film may be made of any material such as polyester resin. Alternatively, the front surface of the sensor substrate 111 according to the first embodiment, the front surface of the back plate 212a of the cell holding portion 212 according to the second embodiment, and the front surface of the back plate 312a of the cell holding portion 312 according to the third embodiment are made white, and light leaking from the reflection surface RS of the plate portion PT can be returned into the plate portion PT by these white surfaces.
In the sensor units SU1, SU2 and commodity selection units 10 and 20 of the first and second embodiments described above, the main boards 12 and 22 support the commodity selection devices 11 and 21 from below, but the present invention is not limited to this. For example, the first connection terminal CT1 may be provided on the rear surface side of the sensor boards 111 and 211 so that the main boards 12 and 22 support the commodity selection devices 11 and 21 from behind. According to this embodiment, since the main boards 12 and 22 are disposed so as to overlap behind the product selection devices 11 and 21, the product selection devices 11 and 21 can be disposed more compactly in the storage portion D2 of the display portion D of the vending machine VM.
In the sensor devices and the like of the first, second, and third embodiments described above, the number of the light sources LS is arbitrary. The light source LS is not necessarily a variable color LED, and may be an LED capable of emitting only a single color such as white or blue. In particular, in the sensor devices SD1 and SD2 according to the first and second embodiments, since the sensor substrates 111 and 211 are provided with the light source LEDs, the commercial sample S can be illuminated in a desired color only by replacing the sensor device SD1 or the like. Specifically, for example, when the commercial sample S illuminated with white so far is to be illuminated with blue, the sensor device SD1 or the like may be changed from a device provided with a white LED to a device provided with a blue LED.
In the sensor device SD1 and the product selection device 11 of the first embodiment, the sensor substrate 111 may be provided with a rear-surface-mounted LED independent of the light source LS, and a specific position of the product sample S may be illuminated at a fixed point independent of the illumination of the product sample S via the light source LS and the light guide plate LGP. By such spot illumination, for example, the commodity price displayed integrally on the commodity sample S can be illuminated. Or such spot lighting may be used to indicate sold out of the goods.
Spot lighting of the product sample S using the rear surface-mounted LED may be employed in the sensor device SD2 and the product selection device 21 of the second embodiment. In this case, an additional through hole is formed in the back plate 212a of the sample holding portion 212 at a position corresponding to the position where the rear surface-mounted LED is provided.
Spot lighting of the product sample S using the rear surface-mounted LED may be employed in the sensor device SD3 and the product selection device 31 of the third embodiment. In this case, similarly to the sensor substrate 111 of the first embodiment, the sensor substrate 311 is disposed on the front side of the back plate 312a of the sample holding portion 312, and the front surface of the sensor substrate 311 is opposed to the reflection surface RS of the light guide plate LGP.
In the main control unit MC of each of the above embodiments, the light source LS of the product selection device provided with the capacitance sensor is caused to emit blue light when the capacitance of the capacitance sensor reaches the first reference value by the user approaching the product sample S with a hand, and the light amount of the light source LS of the product selection device provided with the capacitance sensor is increased for a predetermined time when the capacitance of the capacitance sensor reaches the second reference value by the user approaching the product sample S with a hand, but the control by the main control unit MC is not limited to this. The main control unit MC can change the state of the light source LS in an arbitrary manner in order to visually notify that the user has selected a product and purchased the product. The main control unit MC may change the state of the light source LS only at any one of the time when the user selects a product sample (the time when the capacitance of the capacitance sensor reaches the first reference value) and the time when the user purchases a product (the time when the capacitance of the capacitance sensor reaches the second reference value).
The sensor unit and the product selection unit of each of the above embodiments may not have the main control unit MC. The main control unit MC may be disposed at any other position within the vending machine VM or outside the vending machine VM. The product selection means 10, 20, and 30 can be freely disposed inside the housing portion D1 of the vending machine VM.
In the above embodiments, other light sources such as Laser Diodes (LDs) may be used instead of the LED light sources.
The present invention is not limited to the above-described embodiments as long as the features of the present invention can be maintained, and other embodiments that can be considered within the scope of the technical idea of the present invention are also included in the scope of the present invention.
[ industrial applicability ]
The sensor device, the sensor unit and the like of the present invention can display the article sample more compactly and can prevent the user from selecting the sample by mistake. Therefore, for example, when the sensor device, the sensor unit, and the like of the present invention are used in a vending machine, it is possible to provide a compact vending machine which prevents erroneous purchase of a product and is convenient to use.
