Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a coin detection sensor mounting structure suitable for application to a coin processing device incorporated in a public telephone or the like.

[Prior Art] In recent years, public telephones have become available for a variety of bill payment methods, and in addition to coins, cards can also be used, so it has become necessary to have a coin processing device and a card processing device co-located within the housing. . On the other hand, public telephones are required to be smaller, lighter, and lower in price. Against this background, there is a growing need for a thin coin processing device that can be mounted by being inserted from the front of the housing, and that is thin and occupies a small volume when mounted. In addition, from the perspective of improving serviceability during power outages, there is a need for lower power consumption as various coins such as 10 yen and 100 yen are processed using a local power supply of about 100 mW.
Figure 7 shows a conventional example of a public telephone that incorporates a thin coin processing device from the viewpoint of ease of mounting.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of a coin processing device adopting the coin detection sensor mounting structure according to the present invention, FIG. 2 is a perspective view of a rolling surface conversion track section,
FIG. 3 is an overlapping view of the cross section of the portion indicated by the dashed line in FIG. 2. In addition, No. 9 in the figure
Components and portions that are the same as those in the figures are designated by the same reference numerals, and their explanations will be omitted. In these figures, 70 is a track plate for coin A, 71 is a track plate for coin B, 72 is a coin accumulation plate, 73 is a return funnel, and 74 is a coin storage plate.
75 is a storage track, 75 is a return track, and 76 is a flapper attachment portion for attaching the flapper to the track plate 70. The flapper 65 is biased by a spring (not shown) and has a total of three support points: one of the flapper mounting portions 76 and two support points (not shown) provided on the raceway plate 70 or 71. Supported by points.

As for assembly, the raceway plate 71, flapper 65, coin accumulation plate 72, and return funnel 73 are sequentially attached to the raceway plate 70 so as to overlap in the thickness direction thereof.

The lower rail 55 and rolling support surfaces 56 and 5 on both sides of the first coin processing track 41 shown in FIG.
7. In FIG. 1, it is composed of the front surface of a track plate 70, a lower rail formed on the surface, and the back surface of a track plate 71. 78 is an accumulation track lower rail for coin A, 79 is an overflow track lower rail for coin A, 80 is a return prevention plate for coin A,
81 is a return prevention plate for coin B, and these two prevention plates 8
0 and 81 are integrally provided as in the conventional example shown in FIG. In addition, the second coin processing track 42
is similarly constituted by the surface of the track plate 71, the lower rail 82 formed on the surface, and the back surface of the coin accumulation plate 72. Note that for the first and second sorting windows 48A, 48B and their surroundings, the rolling support surface on one side is constituted by the back surface of the flapper 65.
Further, in this embodiment, the track plate 71 constitutes a rolling support plate whose both surfaces serve as coin rolling support surfaces for the coins A and B, and this and the lower rail 82 are integrally formed. The track plate 70 constitutes the other coin rolling support surface for the coin A, and is connected to the lower rails 78, 79.
is formed integrally with. In this way, the track plate 71
There are first and second coin handling tracks 41 on both sides of the coin handling track 41,
42, both of these tracks are connected to the track plate 71.
Many parts overlap across the board thickness.

FIG. 2 shows the rolling surface conversion raceway section 51, and FIG. 3 is a diagram in which cross-sections of the portion indicated by the dashed line in FIG. 2 are superimposed. The overlapping part is shown with a solid line, and the part with is shown with a broken line. In these figures, 90 is the bottom rail and the coin
It has an inclination in the rolling direction of AB and in the thickness direction of raceway plate 70. 91 is an upper rolling support surface formed on the track plate 70 that slightly supports the upper part of the coin A; 92
is a side rolling support surface that is formed on the back surface of the flapper 65 and supports the side of the coin A.

The regular coin A is supported at three points: the upper rolling support surface 91, the side rolling support surface 92, and the lower rail 90, and passes through the first sorting window 48A. On the other hand, coins such as coin B whose diameter does not meet the tolerance for coin A, or pseudo coins A′ whose diameter meets the tolerance but whose thickness does not meet the tolerance, fall toward the track plate 70 side and the first It falls off from the sorting window 48A. Here, since there is a rolling surface conversion track 51 composed of a sliding support surface 95, a lower rail 96, and a back surface 97 of the flapper 65 below the lower rail 90, the fallen coins A' and B are While sliding on the surface 95, it moves to the second sorting track 52 as shown in FIG. The sliding support surface 95 is composed of an inclined surface and a perpendicular surface, but the sliding surface is characterized by a slope that becomes steeper as it slides down, and this structure allows the coins A' and B to roll smoothly. You can change sides. Note that this support surface 95 may be configured to have a curvature. The thickness of the track plate 71 is that of coin A,
It is desirable that the thickness be about 1/2 or less of the diameter of B. If it becomes thicker than this, the coin will not be able to move smoothly on the rolling surface.

In Fig. 2, coins A' and B rolling on the second sorting track 52 reach the position , but this part of the back of the flapper has a large A diameter cargo passage prevention mechanism 100 (FIG. 3) is provided. This mechanism 1
The effect of 00 is shown below. As aforementioned,
In the first sorting window 48A, thin pseudo coins whose diameter meets the tolerance value but whose thickness does not meet the tolerance value
Since A' falls off, it enters the second sorting trajectory 52.
There will be no problem if this pseudo coin A' falls off at the second sorting window 48B and is ejected, but it is possible that the pseudo coin A' may pass through. In this case, the subsequent erroneous selection process becomes complicated. Therefore, the oversized diameter coin passage prevention mechanism 100 is provided at a location slightly higher than the upper limit of the regular coin B,
The pseudo coin A' is stopped at or in front of the second sorting window 48B, that is, it is blocked in the sorting track 52, thereby preventing it from entering the second accumulation track 32. This pseudo coin A' falls off the second sorting track 52 by opening the flapper 65 and is returned via the return funnel 73 (FIG. 1).

Next, the coin B that has passed through the oversized diameter coin passage prevention mechanism 100 approaches the second sorting window 48B. The regular coin B has an upper rolling support surface 101, a side rolling support surface (the back side of the flapper), and a lower rail 10.
It is supported at three points of 2 and passes through the second sorting window 48B. On the other hand, coins with a diameter of B, such as 5 yen and 50 yen coins
Coins C whose diameter does not meet the tolerance, or pseudo coins A' whose diameter does not meet the tolerance but whose thickness does not meet the tolerance, fall out of the second sorting window 48B and are returned via the return funnel 73. Ru.

Now, this coin processing device requires various electronic sensors for coin accumulation detection, storage detection, material detection, etc., but when the trajectories overlap across a relatively thin plate thickness as described above, it is possible to detect coins within the plate thickness. The idea of embedding the detection sensor and its lead wires is important. In other words, by embedding sensors, it becomes possible for the first time to consider the sensor arrangement and trajectory configuration separately, and the idea of overlapping trajectories also arises.

Therefore, as shown in FIG.
1 and the coin accumulation plate 72 are provided with sensor holder holes 85A to 85G for embedding a coin detection sensor 110 (FIG. 4) to be described later, and grooves 87A and 87B for embedding lead wires of the sensor 110. The sensor holder holes 85A to 85F are provided in the parts of the track plates 70 and 71 through which coins A and B pass, and the grooves 87A and 87B are provided in the track plates 71 to allow the coins A and B to pass through.
It is provided so as to cross the part through which B passes,
This leads the lead wire to a part where coins do not pass.
One end thereof communicates with the sensor holder holes 85E and 85F, respectively. In addition, sensor holder hole 8
Although the lead wire embedding groove of 5C85D is not shown in FIG. 1, it is formed on the back surface of the track plate 71, that is, the surface facing the track plate 70.

The coin detection sensor 110 is composed of a pair of elements that transmit and receive light or magnetism, and in this embodiment, a photocoupler and a magnetic sensor are used.

Next, a method of embedding a photocoupler in the track plate 71 will be described.

FIG. 4 shows how the photocoupler is mounted. In the same figure, 120 is a thin and small board for mounting an LED (not shown), and the hole 8 of the raceway plate 71
It will be implemented to be embedded in 5E. 122 is
The LED is mounted on the back side of the board 120 as an LED terminal. 123 is a lead wire, and 124 is a holding plate for fixing the board 120 in the hole 85E of the raceway plate 71, which is fixed by a gasket 125. 126
is a board on which a phototransistor 127 is mounted, and this board 126 is provided in the hole 85A of the track plate 70 so as to face the board 120, and the phototransistor 127 faces the LED. It constitutes a coin detection sensor 110.

5a, b, and c show the structure of the substrate 52, to which the phototransistor 127 is soldered. 130 is printed wiring, 13
1 is an insertion hole for a lead wire 132. Lead wire 1
32 is inserted into the insertion hole 131 and connected to the printed wiring 130 with solder. The thickness from the tip of the phototransistor 127 to the lead wire 132 is small and sufficient to allow mounting on the track plate 70. The reason for mounting the phototransistor 127 on the track plate 70 after assembling it on the substrate 126 is to ensure good mounting performance, good precision, and ease of repair.

FIG. 6 is an exploded perspective view showing an example of a mounting method when a magnetic sensor is used as the coin detection sensor 110. In the same figure, 140A, 140B are coils, 141A, 141B are ferrite cores, 1

41B is the hole 85G of the coin accumulation plate 72 (see Figure 1)
and is fixed by a presser fitting 142B.

〔Effect of the invention〕

As described above, in the mounting structure of the coin detection sensor according to the present invention, a sensor holder hole and a groove are provided in a relatively thin rolling support plate, and one element of the coin detection sensor consisting of a pair of elements is installed in the sensor holder hole. The lead wire was embedded in the groove communicating with the hole, and the other pair of elements was installed on the rolling support surface provided on both sides of the rolling support plate with the width of the lower rail separated. The processing track can be configured three-dimensionally, making it possible to make the coin processing device more compact, especially significantly thinner.Also, since the lead wire is housed in the groove, there is no need to bundle the wires, making it possible to reduce the cost. Can be assembled. Furthermore, when mounting the sensor, it is better to mount it on a small board and then attach this board to the hole in the rolling support plate, which makes it easier to mount and increases the positioning accuracy of the sensor. Easy to remove.
