DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to coin sorting devices for use in automatic vending machines, coin operated gaming machines and the like.
BACKGROUND ART
The coin sorting devices of various types for sorting coins, tokens or the like have been well known. In Japanese Utility Model Application laid-open publication No. 52-77,797 there is described a coin sorting device of front type having a front plate provided with a coin inserting opening, an outside returning lever and a return opening, and the front plate is assembled with a stationary side plate, a movable side plate and a chute side plate to define a coin sorting passage, a coin acceptance chute and a return chute by which non-acceptable coins inserted from the coin inserting opening are returned to the return opening in the front plate.
Other typical coin sorting devices are also known such as a drop type coin sorting device having a rocking cradle provided with a pair of engaging lugs or pins spaced from each other in a distance corresponding to the diameter of an acceptable coin for sorting the diameter of the coins and means for sorting the quality of coins magnetically by means of magnetic braking force applied to the coins rolling and passing through a magnetic flux in the coin sorting passage.
The front type coin sorting devices have a self contained construction comprising the coin inserting opening and the return opening and therefor may be assembled in automatic vending machines, coin operated gaming machines and other machines easily and compactly, but have an inferior coin quality sorting function to that of the drop type coin sorting device.
In these days, as the use of automatic vending machines, coin operated gaming machines and the like increases, such unfair acts as the automatic vending machines being actuated by use of non-acceptable coins are cunningly carried out in various ways and result in the coin sorting devices being complicated for satisfying the severe requirement for sorting diameters, thicknesses, metallic contents, weight, centerhole, milling and rim at the outer peripheries of the coins in high precision. Accordingly, the manufacturing, especially assembling and adjusting operations require much labor and expense.
DISCLOSURE OF THE INVENTION
It is the object of the present invention to provide a self contained front type coin sorting device having the same superior quality of sorting function as the drop type coin sorting device to avoid the said drawbacks of the conventional front type coin sorting devices and further inhibit perfectly all of the unfair acts which can be considered and to provide a simple and reliable coin sorting device so arranged that the assembling and adjusting operations can be very readily carried out.
For accomplishing the above mentioned object, the present invention solves various problems and difficulties arising in assembling such parts as the diameter sorting cradle and the magnetic coin quality sorting means of the drop type coin sorting device into the frame of front type coin sorting devices.
One of the above mentioned difficulties is that, owing to location of the cradle at an obliquely downward position from the coin inserting opening, different pushing forces applied to the coins which are inserted in the coin inserting opening by the fingers affect the rocking motion of the cradle to create variations in the motion of the cradle. This results in that non-acceptable coins having smaller diameter than that of acceptable coins but having the same metallic contents as that of acceptable coins take the same travel paths as the acceptable coins to pass through the coin acceptance chute. Other problems are that the non-acceptable coins may be inserted into the coin acceptance chute through the return chute from the return opening, and that it is difficult to open the movable side plate magnetically attracted to the coin quality sorting magnet through a keeper by means of the conventional returning lever because a returning lever having a sufficient lever ratio to ope
