Coin feeding apparatus for coin handling machine

Claim 1

A coin feeding apparatus for a coin handling machine comprising a rotatable disk for receiving coins, guide ring means having a circular inner circumference disposed inside of an outer periphery of the rotatable disk for guiding by the inner circumference thereof coins received by the rotatable disk and moved toward the outer periphery of the rotatable disk by centrifugal force produced by the rotation of the rotatable disk, an opening in said guide ring a coin passage communicating with said opening and having a pair of first and second guide rail means and transporting belt means for transporting coins, the coins being transported along the first guide rail means disposed on the side of the rotatable disk, discriminating means for discriminating the denomination of coins and whether or not the coins are acceptable, counting means for counting the value of deposited coins, the discriminating means and the counting means being arranged along the first guide rail means of said coin passage, rotatable guide roller means disposed upstream of said first guide rail means, the first guide rail means extending onto the rotatable disk, said coin feeding apparatus for a coin handling machine further comprising guide means extending along the coin feed direction in the vicinity of said coin passage, said guide means being swingable between a first position where one face of the guide means is smoothly aligned with said inner circumference of said guide ring means and a second position where said face is not smoothly aligned with said inner circumference of said guide ring means, said guide means having a downstream corner portion at an end of said face, said portion being the pint of the guide means closet to the guide roller means when said guide means is in said first position, said first position being further characterized in that a first plane formed tangential to said inner circumference of said guide ring means at said downstream corner portion is spaced at a distance less than the diameter of the smallest diametered coin to be handled from a second plane lying along the first guide rail means, said second position being further characterized in that said downstream corner portion is located essentially in line with said second guide rail means such that the distance between said downstream corner portion and said guide roller means is larger than the largest diametered coin to be handled.
