Each can be made freely without limitation. Therefore, the freedom of manufacture is large, and novel design is adopted to each, and it becomes possible to aim at differentiation from other button devices. Moreover, the harness (not shown) which supplies electric power and a control signal to the reed switch 52, the price display part 53, etc. is arrange | positioned behind the front panel of the plate-shaped member 51, the sample stand 211, etc. It may be made invisible from the front of the panel 201.

The rod magnet 22 of the operation button main body 10 and the reed switch 52 of the substrate 50, for example, as shown in Fig. 3, the operation button 20 is not pressed in the drawing right direction. When not in use, the reed switch 52 is not conducting. For example, as shown in FIG. 4, when the operation button 20 is pressed in the right direction in the drawing and the bar magnet 22 is rotated 90 degrees, the reed switch 52 ) Conducts, current flows, and the switch is operated so that the sales mechanism of goods (not shown) installed in the vending machine 200 operates.

That is, as shown in Fig. 6B, the middle 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 bar magnet 22 If the axial direction and the lead wire direction of the reed switch 52 are arranged in parallel on the same plane, the portion close to the N pole of the bar magnet 22 of the lead wire 52A of the reed switch 52 made of magnetic material It becomes S pole, the contact part 52C side becomes an N pole, and the part near the S pole of the reed switch 52 of the other lead wire 52B becomes an N pole, and the contact part 52C side is an S pole As a result, the lead wires 52A and 52B pull on each other at the contact portion 52C and conduct.

However, when either the bar magnet 22 or the reed switch 52 is rotated by 90 degrees and arranged as shown in Fig. 6A, both the north pole and the south pole of the bar magnet 22 are reed switches ( Since it is equidistant from the contact portion 52C of 52, neither the contact portion 52C side of the lead wire 52A nor the contact portion 52C side of the lead wire 52B is clearly polarized, so that the lead wires 52A and ( 52B do not pull each other at the contact portion 52C and do not conduct.

In addition, the reed switch 52 conducts when the operation button 20 is not pressed in the drawing right direction as shown in FIG. 3, and is pressed in the drawing right direction as shown in FIG. 4 so that the bar magnet 22 is pressed. It may be provided so that it will not become conductive when it rotates 90 degrees, and when the reed switch 52 loses the conduction, it may be comprised so that the sales mechanism of the goods which are not shown in the vending machine 200 installed may operate.

As the detection means, for example, as shown in 9B, the pair of L-shaped magnetic members 30 are symmetrically provided while approaching the north pole and the south pole of the bar magnet 22, The reed switch 52 and the other end of the pair of L-shaped magnetic members 30 are provided close to each other so that the reed switch 52 can conduct, and the bar magnet 22 is operated depending on whether or not the operation button 20 is pressed. ) May be positioned, for example, between the pair of L-shaped magnetic members 30 so as not to be positioned, and thus the reed switch 52 may or may not be conductive.

As the detection means, the rod magnet 22 and the reed switch 52 are brought close to each other, for example, as shown in FIG. 10 (B) so that the reed switch 52 conducts, and the operation button 20 is provided. In accordance with the presence or absence of pressing operation, for example, the plate-shaped magnetic blocking member 32 made of a magnetic material provided to be movable up and down is located between the bar magnet 22 and the reed switch 52 or not to be positioned. In addition, a detection means and a to-be-detected member can also be comprised so that the reed switch 52 may or may not conduct.

For example, as shown in FIG. 11, the magnetic shield member 32 is provided in the trough shape, and the magnetic shield member 32 formed in this way rotates according to the presence or absence of the operation which presses the operation button 20. FIG. The detecting means and the member to be detected may be constituted so as to move or not be located between the bar magnet 22 and the reed switch 52, thereby making the reed switch 52 conduct or not conduct. have.

12, the light emitting means 33 and the light receiving means 34 are provided on the plate member 51 at appropriate intervals in place of the reed switch 52, and at the same time, the light emitting means 33 An optical path changing means 35 for directing the emitted light to the light receiving means 34 is provided in front of the light emitting means 33 and the light receiving means 34 so as to be rotatable, for example, and the optical path changing means 35. ) May be rotated by the operation of the operation button 20 so that the light emitted from the light emitting means 33 may or may not reach the light receiving means 34 to be a detection means and a member to be detected.

The light 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.

In addition, as shown in FIG. 13, for example, as shown in FIG. 13, the optical path changing means 35 is provided so that the reflective surface 36 can be deformed, and the reflective surface 36 is operated by operation of the operation button 20. As shown in FIG. And the light emitted from the light emitting means 33 may reach or not reach the light receiving means 34 to serve as the detection means and the detected member (of the light emitting means 33 reflected by the reflecting surface 36). In order to prevent the light from reaching the light receiving means 34, the light emitting 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 on the reflecting surface 36. Is changed to a convex surface, the light is reflected to the light-receiving means 34 located in front of it (right side of the drawing) because it is reflected in a wide range on the reflective surface 36.).

When the bar magnet 22 or the like is used for the member to be detected, instead of the reed switch 52 as the detection means, the element itself is a Hall element (hole IC) or a magnetoresistive element (MR) using a conventionally known Hall effect. Element) is also possible.

At that time, since the front panel 201 of the vending machine 200 is made of a resin whose linear expansion coefficient is larger than that of metals such as iron and which is easy to deform, the detection member such as the bar magnet 22 and the like are detected. The distance between the Hall element, the magnetoresistive element, etc. used as the means is variable, so the values detected by the Hall element, the magnetoresistive element, etc. of the detection means are also seasonal, the unevenness of the mounting portion, and the amount of goods stored for sale (weight May fluctuate greatly).

Therefore, as shown in FIG. 14, for example, the DC amplifier 38 is connected to the magnetoresistive element 37, and the A / D conversion input device is attached to the voltage amplified by the DC amplifier 38. When a microcomputer 39 is connected to be processed and the front panel 201 of the vending machine 200 is open and closed, for example, a few seconds after the front panel 201 is closed (the effect of vibration when opened) In order to avoid this, the measurement after several seconds is preferable, and the operation voltage is detected by detecting the voltage when the operation button 20 of the front panel 201 is not operated by the door switch SW. It is desirable to correct this.

For example, the output voltage of the magnetoresistive element 37 when the operation button 20 is not operated is preferably 0V. However, since the bar magnet 22 is affected, the output voltage does not become 0V. For example, when the output voltage of the magnetoresistive element 37 when the operation button 20 is operated is 25 mV, for example, is 5 mV, the microcomputer 39 takes an intermediate value and sets the threshold as 15 mV. A few seconds after 201 is closed, the output voltage of the magnetoresistive element 37 when the operation button 20 is not operated is 15 mV, and the output voltage of the magnetoresistive element 37 when the operation button 20 is operated. For example, when it becomes 35 mV, even when the operation button 20 is not operated, the output voltage of the magnetoresistive element 37 shows 15 mV which is a threshold value, and if it does not correct, it will malfunction.

Therefore, when the output voltage of the magnetoresistive element 37 when the operation button 20 is not operated after a few seconds after the front panel 201 is closed is 10 mV, the threshold value is 25 mV (15 mV). + 10mV).

In addition, this kind of correction may be performed regularly, or the temperature detection means installed in the vending machine 200 may be performed at a temperature outside the predetermined temperature (for example, 10 ° C) from the set temperature (for example, 20 ° C). good. In addition, the threshold value may be corrected, and the output voltage of the magnetoresistive element 37 may be corrected and compared with a predetermined threshold value.

For this reason, even if the temperature, the unevenness of the mounting portion, the amount (weight) of the stored product, etc. may vary greatly, the button device 100 operates normally without malfunction.

In addition, the product information display part 54 of the board | substrate 50 is the window member 57 which consists of opaque material provided with the opening part 56 of predetermined size at predetermined space | interval as shown, for example to 15 (A). ) Is placed on the front side, and the back side is alternately displayed as COLD and HOT by printing or the like at predetermined intervals from the left side of the drawing, and is movable in the left and right direction of the drawing by the gear motor 58 installed at the right end of the drawing. The movable printing member 59 is arrange | positioned, and the fixed display member 60 marked COLD by printing etc. is provided in the part which opposes the opening part 56 of the left end of a figure at the back side again.

In Fig. 15, 61 is a resin disc fixed to the rotational shaft of the gear motor 58, and 62 is integrally molded with the disc 61, and the tip portion eccentrically protrudes from one side of the disc 61 is formed.

Moreover, when the goods sample 210 installed in the sample stand 211 is replaced without permission, even if the operation button 20 of the button apparatus 100 corresponding to the goods is operated, detection of whether the purchase operation is performed or not is performed. It is also possible to configure such that the selling operation of the product corresponding to the newly installed product sample is stopped.

To this end, a predetermined first coil 70 is attached to the bottom of the product sample 210 installed on the sample stage 211 (see FIGS. 1 and 17), and the first coil 70 approaches and Two coils 71 are provided on the plate member 51 of the substrate 50, and as shown in Fig. 18, the first coil 70 forms an absorption circuit 72 with a capacitor, and the second coil. 71 forms an oscillation circuit 73 with an amplifier and a condenser.

Then, the buffer circuit 72, the rectifying means 75, the comparator 76, and the like are connected to each other so as to output the stop selling signal in accordance with the oscillation level in the oscillation circuit 73.

For example, the absorption circuit 72 makes the first coil 70 and the second coil (by making the resonance frequency determined by the first coil 70 and the capacitor the same as the oscillation frequency of the oscillation circuit 73). When 71 approaches, the oscillation energy of the oscillation circuit 73 is applied from the second coil 71 to the first coil 70. Since the absorption circuit 72 resonates and the impedance approaches zero, the total energy is generated. Is absorbed by the absorption circuit 72 and the oscillation is stopped. Therefore, the signal of the oscillation frequency shown in the A portion disappears, and the signal does not appear in the B and C portions.

Therefore, when the comparator 76 outputs a predetermined voltage, the first coil 70 and the second coil 71 do not approach each other. In other words, the predetermined product sample 210 is the sample stage 211. In this case, even if the operation button 20 of the button device 100 corresponding to the product is operated at that time, whether the purchase operation is performed or not is not detected, it is currently installed on the sample stand 211. It is possible to configure a sales mechanism (not shown) of the vending machine 200 so that the selling operation of the product corresponding to the product sample 210 is stopped. In addition, when the oscillation amplitude of the oscillation circuit 73 becomes smaller than the predetermined width, it is also possible to set it as the structure which operates as mentioned above.

With this configuration, the problem that the sales product is replaced without permission by the vending machine 200 installed in front of the store for the purpose of selling a specific product without permission to the person who rented the vending machine 200 has been solved.

In addition, since this invention is not limited to the said embodiment, various deformation | transformation is possible in the range which does not deviate from the meaning described in the claim.
