ABSTRACT:

FIELD OF THE INVENTION
This invention relates generally to a coin selector for sorting out whether a deposited coin is genuine or not by rolling thereof. This invention more particularly relates to a rolling style coin selector which is used for game machines such as slot machine, pachinko-slot machines and other devices. The terminology “coin” used in this specification should be interpreted to include coins of a small disk shape including currency. The terminology “coin” should also be construed in this specification to include disk-like medals and tokens used in games, etc.
BACKGROUND OF THE INVENTION
Until now, rolling type coin selectors have been used for medal/awards game machines and pachinko-slot machines, etc. A rolling style coin selector is disclosed in Japanese Utility Model Application 4-23240 by the present applicant. The rolling coin selector which is described in Japanese Utility Model Application 4-23240 is laid-open to public inspection as Japanese Utility Model Disclosure 6-25963. This rolling coin selector is also disclosed in U.S. Pat. No. 5,293,981.
The rolling coin selector which is disclosed in Japanese Utility Model Application 4-23240 is summarily shown by a perspective view in
FIG. 14A. A
sectional view of this rolling coin selector is also shown in FIG.
14
B. In rolling coin selector which is shown in
FIGS. 14A and 14B
, the coin is deposited or inserted into an upper charge mouth
1
. The deposited coin rolls and falls on straight line rail
7
, which is formed at the lower edge of large frame
4
. When the coin A is genuine, the roll continues, being held between thin plate guide
10
and door board
5
(refer to FIG.
14
B). When the coin A is not genuine and has a small diameter, the coin A falls, dropping off of guide
10
or door board
5
.
When coin A is not genuine and has a large diameter, the coin A does not roll, being stopped by guide
10
, etc. In this case, when door board
5
is moved against a spring (not shown), arm
11
will also be moved, via existing hinge shaft
8
. Thus, the coin which is stopped by guide
10
, etc. falls.
A greatly improved rolling coin selector is disclosed in Japanese Patent Application 10-324355 by the present applicant. The rolling coin selector which is described in Japanese Patent Application 10-324355 is laid-open to public inspection as Japanese Patent Disclosure 2000-123217. The rolling style selector, which is disclosed in Japanese Patent Application 10-324355 is summarily shown on the front elevation view of attached FIG.
15
.
FIG. 16
is a summary sectional view in which
FIG. 15
is observed from the left side. The rolling coin selector which is disclosed in Japanese Patent Application 10-324355 is used in the condition shown in FIG.
16
. This rolling coin selector is used, by forming a rough section-V-shaped small groove
56
by means of paired rollers
53
and
55
. In this condition, coin C is inserted into upper part opening
21
of the selector. The inserted coin C is guided and rolled via circular arc way
22
(refer FIG.
15
). Then, when this coin C, which is sorted out is genuine, circular arc way
22
will be passed through. That is, the lower edge of genuine coin C is guided by circular arc way
22
. Simultaneously, the upper edge of genuine coin C is guided by small groove
56
of paired rollers
53
and
55
. Therefore, when the coin C is a genuine coin, circular arc way
22
will be smoothly passed.
In this practical example, paired rollers
53
and
55
are freely rotatable. As a result of this, genuine coin C will smoothly and swiftly pass circular arc way
22
. When the coin which is put in opening
21
is not genuine, circular archway
22
win not be passed. For example, when the diameter of the deposited coin is small, circular arc way
22
will not be passed. That is to say, when the diameter of deposited coin is small, the coin falls, deviating from the above small groove
56
. However, when the small diameter coin vibrates, the apparent size of this coin increases and becomes like a genuine coin. In this case, spring
57
acts on this coin (refer FIG.
16
). That is, spring
57
will absorb the vibration of the coin. As this result, the small diameter coin falls, coming off from paired rollers
53
and
55
. When the diameter of coin which is deposited in opening
21
is great, circular arc way
22
will also not be passed. For example, the upper edge of diameter-greater coin is struck to and stopped at rollers
53
and
55
. In this case, by opening and closing the door
31
around the above hinge shaft
32
, the coin, with the big diameter, falls.
SUMMARY AND OBJECTS OF THE INVENTION
The invention is based on the observation that the conventional rolling style coin selector was laterally big. The size generally was too great as to the conventional roll style coin selector. In addition, there was a problem that the conventional roll style coin selector was heavy, since most parts were metallic.
It is an object of the invention to solve the above-mentioned problems.
It is another object of the invention to decrease the size of whole selector and to provide a selector that is lighter on the whole.
According to the invention, a coin selector is provided including synthetic resin molded products.
Still another object of the invention is to provide simplified size change features with the change of the selection coin.
According to the invention, a coin rolling type selector is provided comprising a base element which has a shape such as a roughly square thick standing up plate, a rail arranged on this base element, and a roller with a groove. The roller is freely rotatable and arranged above this rail. The roller guides the upper edge of the rolling coin.
The rail is preferably a slender metal and is detachably fixed on the base element. The roller is preferably a resin molded product and is detachably fixed on said base element.
