In addition, a harness (not shown) that supplies power and control signals to the reed switch 52, the price display unit 53, and the like is arranged behind the plate member 51 and the front panel of the sample table 211, and the front panel 201 starts from the front. You can also hide it.
00 26 ]
And the bar switch 22 of the operation button main body 10 and the reed switch 52 of the substrate 50 are not connected to the reed switch 52 when the operation button 20 is not pushed rightward in the drawing as shown in FIG. For example, as shown in FIG. 4, when the operation button 20 is pushed rightward in the drawing and the bar magnet 22 rotates 90 degrees, the reed switch 52 is turned on and current flows, and the switch operates to operate the vending machine 200. The merchandise sales mechanism (not shown) is installed so as to operate.
00 27 ]
That is, as shown in FIG. 6B, the intermediate portion of the N and S poles of the bar magnet 22 and the contact portion 52C of the reed switch 52 face each other, and the axial direction of the bar magnet 22 and the reed switch 52 The lead wire 52 of the reed switch 52 made of a magnetic material is disposed close to the N pole of the bar magnet 22 as the S pole, and the contact portion 52C. The side is the N pole, the portion of the other lead wire 52B near the S pole of the reed switch 52 is the N pole, and the contact portion 52C side is the S pole, so the lead wires 52A and 52B are the contact portion 52C. They attract each other and become conductive.
00 28 ]
However, when either one of the bar magnet 22 or the reed switch 52 is rotated 90 degrees so as to be arranged as shown in FIG. 6A, both the N pole and the S pole of the bar magnet 22 are contact parts 52C of the reed switch 52. Therefore, neither the contact part 52C side of the lead wire 52A nor the contact part 52C side of the lead wire 52B is clearly polarized, so that the lead wires 52A and 52B can attract each other at the contact part 52C. There is no conduction.
00 29 ]
The reed switch 52 is turned on when the operation button 20 is not pushed rightward in the drawing as shown in FIG. 3, and is pushed rightward in the drawing as shown in FIG. It may be configured so that it does not conduct when rotated, and a merchandise sales mechanism (not shown) provided in the vending machine 200 operates when the reed switch 52 is no longer conducting.
00 30 ]
As a detected means, for example, as shown in FIG. 9B, a pair of L-shaped magnetic members 30 are provided symmetrically close to the north and south poles of the bar magnet 22, and the reed switch 52 is conductive. The reed switch 52 and the other end of the pair of L-shaped magnetic members 30 are placed close to each other, and the bar magnet 22 moves up and down, for example, depending on whether or not the operation button 20 is pressed. It can also be configured such that it is positioned between the L-shaped magnetic members 30 or is not positioned so that the reed switch 52 is turned on or off.
00 31 ]
As the detected means, the bar magnet 22 and the reed switch 52 are provided close to each other so that the reed switch 52 becomes conductive, for example, as shown in FIG. For example, the plate-like magnetic shielding member 32 made of a magnetic material provided so as to be movable up and down is positioned between the bar magnet 22 and the reed switch 52, or is not positioned so that the reed switch 52 becomes conductive, The detection means and the member to be detected can also be configured so as not to conduct.
00 32 ]
The magnetic shielding member 32 is provided in a bowl shape as shown in FIG. 11, for example, and the magnetic shielding member 32 thus formed rotates depending on whether or not the operation button 20 is pressed, and the bar magnet 22 and the reed switch. The detecting means and the member to be detected can be configured such that the reed switch 52 is turned on or off, so that the reed switch 52 is turned on or off.
00 33 ]
Further, as shown in FIG. 12, instead of the reed switch 52, the light emitting means 33 and the light receiving means 34 are provided on the plate member 51 at an appropriate interval, and the light emitted from the light emitting means 33 is received by the light receiving means 34. The light path changing means 35 is directed to the light emitting means 33 and the light receiving means 34 so as to be rotatable, for example, and the light path changing means 35 is rotated by the operation of the operation button 20 and comes out of the light emitting means 33. It is also possible to configure the detection means and the member to be detected so that the light reaches the light receiving means 34 or does not reach it.
00 34 ]
The optical path changing means 35 can be formed by combining a light collecting means, a light scattering means, a prism, an optical fiber, and the like.
00 35 ]
Further, as shown in FIG. 13, for example, as shown in FIG. 13, the optical path changing means 35 is provided so that the reflecting surface 36 can be deformed, and the reflecting surface 36 is deformed by operation of the operation button 20, and light emitted from the light emitting means 33 is received. The detection means and the member to be detected can be made so as to reach or not reach the means 34 (in order to prevent the light of the light emitting means 33 reflected by the reflecting surface 36 from reaching the light receiving means 34) The means 33 can be provided at the focal point of the reflecting surface 36. On the other hand, the light emitted from the light emitting means 33 is reflected in a wide range by the reflecting surface 36 when the reflecting surface 36 changes to a convex surface. The light also reaches the light receiving means 34 located on the right side).
00 36 ]
When a bar magnet 22 or the like is used as the member to be detected, the detecting means is a Hall element (Hall IC) or magnetoresistive element (MR element) that utilizes a well-known Hall effect instead of the reed switch 52. Can also be used.
00 37 ]
At that time, since the front panel 201 of the vending machine 200 is made of a resin having a larger linear expansion coefficient than metals such as iron and being easily deformed, a detected member such as a bar magnet 22 and a hole used as a detecting means. The distance to the element, magnetoresistive element, etc. is likely to fluctuate, so the value detected by the detecting element, such as the hall element, magnetoresistive element, etc. is also seasonal, unevenness of the installation part, the amount of goods stored for sale (weight) ) And so on.
00 38 ]
Therefore, for example, as shown in FIG. 14, a DC amplifier 38 is connected to the magnetoresistive element 37, and the voltage amplified by the DC amplifier 38 is connected so as to be processed by a microcomputer 39 with an A / D conversion input device. For example, when the front panel 201 of the vending machine 200 is opened and closed, a few seconds after the front panel 201 is closed (measurement after a few seconds is preferable to avoid the influence of vibration when the front panel 201 is closed. It is preferable to correct the operating voltage by detecting the voltage when the operation button 20 is not operated).
00 39 ]
For example, the output voltage of the magnetoresistive element 37 is preferably 0 V when the operation button 20 is not operated, but it is not 0 V because of the influence of the bar magnet 22, for example, 5 mV. When the output voltage of the magnetoresistive element 37 when the button 20 is operated is 25 mV, for example, the microcomputer 39 takes an intermediate value and sets the threshold value to 15 mV, but a few seconds after the front panel 201 is closed. When the operation button 20 is not operated, the output voltage of the magnetoresistive element 37 is 15 mV, and when the output voltage of the magnetoresistive element 37 is 35 mV when the operation button 20 is operated, the operation button 20 is operated. Even if not, the output voltage of the magnetoresistive element 37 shows a threshold value of 15 mV. It made.
00 40 ]
Therefore, when the output voltage of the magnetoresistive element 37 is 15 mV when the operation button 20 is not operated a few seconds after the front panel 201 is closed, the threshold voltage is 25 mV (15 mV + 10 mV) because it is 10 mV higher. ).
00 41 ]
This type of correction may be performed periodically or whenever the temperature detecting means provided in the vending machine 200 deviates from a set temperature (for example, 20 ° C.) by a predetermined temperature (for example, 10 ° C.). good. Further, without correcting the threshold value, the output voltage of the magnetoresistive element 37 may be corrected and compared with a predetermined threshold value.
00 42 ]
For this reason, even if the air temperature, the unevenness of the installation part, the amount (weight) of the stored product, etc. may fluctuate greatly, the button device 100 operates normally without malfunctioning.
00 43 ]
For example, as shown in FIG. 15A, the product information display unit 54 of the substrate 50 has a window member 57 made of an opaque material having openings 56 of a predetermined size provided at predetermined intervals on the front side. COLD and HOT are alternately displayed on the back side of the drawing by printing or the like at a predetermined interval from the left side of the drawing, and a movable printing member 59 is arranged so as to be movable in the horizontal direction of the drawing by a gear motor 58 provided at the right end of the drawing. On the back side, a fixed display member 60 displayed as COLD by printing or the like is provided in a portion facing the opening 56 at the left end of the drawing.
00 44 ]
In FIG. 15, reference numeral 61 denotes a resin disc fixed to the rotating shaft of the gear motor 58, and 62 denotes a tip portion that is integrally formed with the disc 61 and is formed to protrude eccentrically on one side of the disc 61. Snap formed in the shape of two and divided into two in the axial direction, 63 is a T-shaped resin crank member having a long hole 64 into which a flange portion of the snap 62 is inserted, and 65 is a crank member 63 The snap is integrally formed with the crank member 63 on one side, and the snap 65 is inserted into a hole (not shown) provided at one end of the movable printing member 59 and connected to each other.
00 45 ]
Therefore, the COLD indication of the fixed display member 60 and the COLD and HOT indications of the movable printing member 59 are obtained by driving the gear motor 58 as shown in FIG. When the snap 62 portion is moved to the right side of the drawing, the movable printing member 59 is also moved to the right side of the drawing, and the COLD indication of the fixed display member 60 can be seen from the opening 56 at the left end of the drawing of the window member 57. Is seen from the other opening 56 of the window member 57, and the gear motor 58 is driven to move the snap 62 portion of the disc 61 attached to the rotating shaft to the left side of the drawing as shown in FIG. The movable printing member 59 also moves to the left side of the drawing, and the COLD indication of the fixed display member 60 is covered with the HOT display portion on the left side of the drawing of the movable printing member 59, and the opening 56 of the window member 57. Luo only the display of the HOT of the movable printing member 59 is visible.
00 46 ]
For this reason, it is necessary to change the display of the product information display unit 54 when, for example, a product that has been cooled and sold is replaced with a product that is sold by heating. However, the change can be easily made by configuring the gear motor 58 so that it can be operated by one switch operation.
00 47 ]
In addition, when a product is heated and sold and automatically cooled depending on the time and temperature, or when it is possible to communicate with a sales center via communication means, the temperature of the next day Can be switched automatically at night after receiving the forecast, or by an appropriate instruction from a sales center or the like.
00 48 ]
Further, since the movable printing member 59 and the crank member 63 are connected via the snap 65, both can be connected and separated easily. Therefore, it is possible to provide a customer who desires an inexpensive apparatus without providing the gear motor 58 and manually moving the movable printing member 59 to change the display content. Further, since the fixed display member 60 is provided on the end portion side, even if the movable printing member 59 is moved in the left-right direction of the drawing in order to switch the display, the end portion may collide with the panel or frame of the vending machine 200. There is no.
00 49 ]
The product information display unit 54 includes a gear motor 58 and a movable printing member 59 as shown in FIG. 16, for example, that is, the gear motor 58 is provided on both the left and right sides of the drawing. The A movable printing member 59 on which COLD and HOT (only the initial letter is shown in the drawing) are alternately printed at a predetermined interval is attached to the front side, and both of them are mounted as shown in FIG. When the movable printing member 59 is moved to the right side of the drawing, the indication of COLD is visible from the opening 56 of the window member 57 described in FIG. 15, and both the movable printing members 59 are moved to the left side of the drawing as shown in FIG. When moved to, the display of HOT can be seen from the opening 56 of the window member 57. When the two movable printing members 59 are moved away from each other as shown in FIG. In 59, the HOT display can be seen from the opening 56 of the window member 57, and in the movable printing member 59 on the right side of the drawing, the COLD display can be seen from the opening 56 of the window member 57.
00 50 ]
In addition, when the product sample 210 installed on the sample table 211 is replaced without permission, even if the operation button 20 of the button device 100 corresponding to the product is operated, it is detected whether or not the purchase operation has been performed. It is also possible to prevent the sales operation of the product corresponding to the newly installed product sample from being stopped.
00 51 ]
For this purpose, a predetermined first coil 70 is attached to the bottom of the product sample 210 to be placed on the sample table 211 (see FIGS. 1 and 17), and the second coil is brought close to the first coil 70. As shown in FIG. 18, the first coil 70 forms an absorption circuit 72 with a capacitor, and the second coil 71 oscillates with an amplifier and a capacitor. A circuit 73 is formed.
00 52 ]
Then, the buffer circuit 74, the rectifying means 75, the comparator 76, and the like are connected to output a sales stop signal according to the oscillation level in the oscillation circuit 73.
00 53 ]
For example, the absorption circuit 72 has a resonance frequency determined by the first coil 70 and the capacitor equal to the oscillation frequency of the oscillation circuit 73, so that when the first coil 70 and the second coil 71 approach each other, The oscillation energy of the oscillation circuit 73 is given from the second coil 71 to the first coil 70. However, since the absorption circuit 72 resonates and the impedance is close to zero, all energy is absorbed by the absorption circuit 72. Since the oscillation stops, the signal of the oscillation frequency that appeared in the portion A disappears, and no signal appears in the portions B and C.
00 54 ]
For this reason, when the comparator 76 outputs a predetermined voltage, the first coil 70 and the second coil 71 are not close to each other. In other words Since the predetermined product sample 210 is removed from the sample table 211, even if the operation button 20 of the button device 100 corresponding to the product is operated at that time, it is not detected whether or not the purchase operation has been performed. Thus, it is possible to configure a sales mechanism (not shown) of the vending machine 200 so that the sales operation of the product corresponding to the product sample 210 currently installed on the sample table 211 is stopped. It is also possible to adopt a configuration that operates as described above when the oscillation amplitude of the oscillation circuit 73 becomes smaller than a predetermined width.
00 55 ]
With this configuration, the vending machine 200 that is installed at the store for the purpose of selling a specific product has the disadvantage that the sold product can be replaced without permission from the lender of the vending machine 200 without permission. It will be resolved.
00 56 ]
In addition, since this invention is not limited to the said embodiment, various deformation | transformation implementation is possible in the range which does not deviate from the meaning as described in a claim.
00 57 ]
For example, instead of the coil spring 28, a rubber-like elastic body 28A as shown in FIG. 19 can be used.
00 58 ]
Further, as shown in FIG. 20, the product information display unit 54 performs a desired display (for example, HOT, COLD) by printing or the like on the movable printing member 59A pivotally supported so as to be mechanical (gear driven). , Belt drive) or manual switching. The product information display unit 54 is not necessarily provided.
00 59 ]
Moreover, as shown in FIG. 21, the cover member 40 which consists of a nonmagnetic body which covers the bar magnet 22 can also be attached to the back member 12 so that attachment or detachment is possible. By attaching such a cover member 40, it is possible to prevent magnetic powder such as iron powder from adhering to the bar magnet 22.
