O Scope of Utility Model Registration Request A screening coil for inspecting the properties of coins inserted from the coin slot is placed in close proximity to the rolling coin path,
In a coin sorting device that determines the authenticity of input coins based on the output of the sorting coil, the coin sorting device is arranged along the coin passage so as to sandwich the sorting coil, and detects an input coin rolling in the coin passage and generates a detection signal. 1. A coin sorting device comprising two detectors that output a coin, and the time width between the detection signals of these detectors being used as a sorting period for determining whether an inserted coin is genuine or false.

Claims (2)

[Scope of utility model registration request] (1) A coin sorting device in which a sorting coil for detecting the properties of input coins is arranged along a coin path, and authenticity is determined by a sorting signal based on the output of the sorting coil.
A coin sorting system characterized in that a period for determining the authenticity of an input coin is determined by detecting the transfer position of the input coin, and when a predetermined sorting signal is generated within this period, the coin is sorted as a genuine coin. Device. (2) Utility Model Registration Scope of Claims In the coin sorting device according to claim 1, detectors for detecting the transfer position of the input coins are arranged in front and rear of the sorting coil with respect to the transfer direction of the input coins. A coin sorting device characterized in that a sorting period for input coins is determined by these detectors. -(3) In the coin sorting device according to claim 1 or 2 of the utility model registration claim, a first flip-flop to which the sorting signal is set and input, when this first flip-flop is in the set state. The second flip-flop is set when the sorting signal appears, and the output of a detector located in front of the sorting coil in the direction of transfer of input coins is set as input, and the output of a detector other than the aforementioned detector is set as input. a third flip-flop having a reset input and providing a reset input to the first and second flip-flops when in the reset state, the third flip-flop being placed in the set state and then in the reset state; A coin sorting device characterized in that an input coin is determined to be "true" when a first flip-flop is placed in a set state before being placed.
