Abstract
Abstract Herein disclosed is a coin handling apparatus such as a coin packaging apparatus which is free from any trouble that would be caused when the power supply service is interrupted or when the power supply circuit is carelessly broken. The coin handling apparatus includes a rotary solenoid which can rotate back and forth at a predetermined angle thereby to control the opening and closing operations of the guide passage by a rotary pin. Further inclusive is a power source detecting circuit which is made operative to detect the existence of the power supply to the coin handling apparatus thereby to generate output signals respectively corresponding to the existence and nonexistence of the power supply. A drive circuit is further included and made responsive to the output signals of the power source detecting circuit thereby to drive the rotary solenoid so that the rotary pin may open the guide passage in response to the output signal corresponding to the existence of the power supply, until the number of the coins conveyed to a coin accumulating cylinder reaches a predetermined value, and may close the guide passage in response to the output signal corresponding to the nonexistence of the power supply.

Claim 1
Independent Claim
317 words
A coin handling apparatus including: selecting means for selecting a predetermined kind of coins from a plurality of coins; a guide passage disposed adjacent to said selecting means for guiding the selected coins therethrough; conveyor means for conveying said selected coins on said guide passage; counting means disposed for counting the number of the coins being conveyed through said guide passage; means disposed downstream of said guide passage for accumulating the coins having been conveyed thereto; and blocking means disposed in said guide passage downstream of said counting means for normally opening said guide passage and for closing said guide passage, when the number of the coins having been conveyed to said accumulating means reaches a predeteremined value; thereby to block the succeeding coins, wherein the improvement comprises: passage control means for controlling the opening and closing operations of said blocking means; a power source detecting circuit for detecting the existence of the power supply to said coin handling apparatus thereby to generate output signals respectively corresponding to the existence and nonexistence of said power supply; and a drive circuit responsive to the output signals of said power source detecting circuit to drive said passage control means so that said blocking means opens said guide passage in response to the output signal corresponding to the existence of said power supply, until said predetermined value is reached, and closes said guide passage in response to the output signal corresponding to the nonexistence of said power supply, said blocking means including a rotary pin having a notched portion and positioned in one of the side walls of said guide passage such that it rotates at a predetermined angle to open said guide passage, when said notched portion coextends with the inner side of the corresponding side wall of said guide passage, and closes said guide passage when said notched portion protrudes at said predetermined angle into said guide passage.
