Description

[Detailed description of the device]

[Industrial applications]

The present invention relates to an article or an article selection device used in an automatic tea dispenser or the like.

[Prior art]

To obtain the desired product or article from the vending machine, press the operating section of the product selection device that includes the nameplate etc. on which the name of the product you are trying to obtain, etc. Products are selected and come out. Currently, a commonly used product selection device includes a printed circuit board having a plurality of conductor patterns formed on the back surface thereof, and a selection button arranged so as to form a predetermined selection circuit. Two terminal legs of the selection button are inserted from the front surface side of the printed circuit board into two holes penetrating each pattern, and the terminal legs are soldered to the pattern on the rear surface side. When the corresponding operation part of the nameplate located on the front face of the selection button is pressed, the selection button is closed, and the two corresponding patterns are connected to form a predetermined selection circuit, which is related in the vending machine to release the product. Activate the mechanical part.

[Problems to be solved by the device]

However, the above-mentioned selection button is often mounted with the main body slightly floating from the substrate. When the operator presses the select button, the operator exerts different amounts of force on it, which also acts on the soldering part of the terminal leg. Therefore, since the load also acts on this soldering part, if it is used for a long time, the contact may be poor at the soldering part due to repeated load, or the joint may come off, so that it will be electrically connected even if the selection button is pressed. It causes the trouble of not doing. Therefore, it is an object of the present invention to provide a product or article selection device that does not have the above-mentioned problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, according to the present invention, an article selection device includes a printed circuit board having a plurality of conductive patterns formed with two holes, and each of the adjacent conductive patterns. A plurality of selection buttons each having a pair of leg terminals that are respectively inserted into one of the holes, and one end and the other end are inserted into the one hole and the other hole of the conductor pattern, respectively. A pair of jumper wires, and one end of each of the pair of jumper wires is inserted into the one hole of the adjacent conductor pattern together with the pair of leg terminals of each selection button to supply the same electric current. Soldered to the conductor pattern, the other ends of the pair of jumper wires are inserted into the other holes of the adjacent conductor patterns and soldered to the conductor pattern.

[Action]

The selection button closes when its body is pressed,
The pair of leg terminals are connected to a predetermined conductor pattern via jumper wires, and thus form a predetermined selection circuit. The force of pressing the select button also acts on the leg terminals, but even if one end of the jumper wire moves with the leg terminal and comes off the conductor pattern, the other end of the jumper wire is joined to the conductor pattern. Therefore, no large force acts on the joint between the other end of the jumper wire and the conductor pattern.

【Example】

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts. FIG. 1 is an overall perspective view of an automatic tea dispenser 1, which is a type of automatic vending machine. Place a cup or the like (not shown) on the pedestal 2 having a slatted structure, and press the operation part of the selection nameplate 3 on which the name of the product or article is displayed, and the desired tea is supplied from the hot water supply port 4. It comes out. FIG. 2 is a partial cross-sectional view of the selection nameplate 3, which is a printed circuit board.
10 is provided with a selection button 11. There is a push-in plate 13 on the front side of the selection button 11, and when the required operation part of the name plate 3 is pushed, the push-in plate 13 moves and pushes the protruding part of the selection button 11. FIG. 3 is a partial side view taken along the line III-III of FIG.
FIG. 4 is a partially enlarged sectional view showing the relationship between the selection button 11 and the printed circuit board 10, and FIG. 5 shows the back surface of the printed circuit board 10. In particular, as is clear from FIG. 5, a plurality of (only two are shown in the figure) conductor patterns 14 are provided on the back surface of the printed circuit board 10.
15 is formed, and the leg terminals 11a and 11b of the selection button 11 are inserted together with one end of the jumper wire 17 into the hole 16 formed in the printed circuit board 10 and soldered (FIG. 4). Also,
The other end of the jumper wire 17 is soldered to the conductor patterns 14 and 15 at a portion apart from the leg terminals 11a and 11b. In the article selection device having the above-described structure, when the push-in plate 13 is pushed through the name plate 3, the protruding portion of the selection button 11 is pushed and closed, so that the conductor patterns 14 and 15 are brought into conduction and the required selection circuit. To form. Since the jumper wire 17 is joined to the leg terminals 11a and 11b, when the leg terminals 11a and 11b are detached from the conductor patterns 14 and 15, they are detached together. In this case, the conductor patterns 14 and 15 are selected buttons 11. Is connected via two jumper wires 17,
Similarly, a desired selection circuit is formed.

[Effect of device]

As described above, according to the present invention, the article selection device is
A printed circuit board on which a plurality of electric conductor patterns each having one hole formed therein and a pair of leg terminals respectively inserted into one holes of each of the adjacent electric conductor patterns are provided. A selection button, and a pair of jumper wires having one end and the other end inserted in one hole and the other hole of the conductor pattern, respectively.
Each one end of the pair of jumper wires is inserted into the one hole of the adjacent conductor pattern together with the pair of leg terminals of each selection button and soldered to the conductor pattern. The other ends of the pair of jumper wires are inserted into the other holes of the adjacent conductor patterns and soldered to the conductor patterns. Therefore, since the force at the time of operating the selection button does not act on the other ends of the pair of jumper wires, even if the leg terminals and the respective one ends of the jumper wires are integrally separated from the conductor pattern, The required selection circuit can be formed, and the function can be maintained for a long period of time.
