Claim:
A coin bar storage comprising: a casing; a coin bar tray that is provided in said casing so as to be drawn out from and stored into said casing, and that has a plurality of set sections in which set coin types are respectively pre-set to assign a coin type to each of said set sections; a plurality of set coin type presence confirmation sections, each of which is provided in a corresponding one of said set sections of said coin bar tray, each of said set coin type presence confirmation sections confirming whether or not a coin bar of the set coin type is set in the corresponding one of said set sections, and outputting a confirmation result which indicates whether or not a coin bar of the set coin type is set; and a management section that manages a present amount of coin bars in said coin bar tray based on the confirmation result from each of said set coin type presence confirmation sections, wherein each of said set sections includes: a bottom face having a rectangular shape; a pair of supporting points provided on one side in a long side direction of the bottom face and having a gap therebetween; and a supporting section provided on an opposite side to the one side in the longitudinal direction of the bottom face and having an arc shape, each of said set coin type presence confirmation sections includes two magnetic sensors that detect a magnetic characteristic of a set coin bar that is set in said set section and that respectively output a detection result, and said two magnetic sensors are arranged on the bottom face and spaced apart in the long side direction so that one of the two magnetic sensors is arranged on the opposite side, said two magnetic sensors are configured such that in a case where a coin bar of a set coin type is set in said set section, an error margin between a detection result from the one of said two magnetic sensors and a detection result from the other of said two magnetic sensors is within an allowable range, and each of said set coin type presence confirmation sections further includes a confirmation section which confirms whether or not a coin bar of a set coin type is set in said set section based on whether or not the error margin between the detection results is within the allowable range.
