a coin bar tray that is provided in the casing so as to be drawn out from and stored into the 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 the set sections; a set coin type presence confirmation section that is provided in all of the set sections of the coin bar tray, that respectively confirms whether or not coin bars of the set coin types is set, and that outputs a confirmation result; and a management section that manages a present amount of coin bars in the coin bar tray based on the confirmation result from the set coin type presence confirmation section. ## Claims ### Claim 1 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 set coin type presence confirmation section that is provided in all of said set sections of said coin bar tray, that respectively confirms whether or not coin bars of the set coin types is set, and that outputs a confirmation result; and a management section that manages a present amount of coin bars in said coin bar tray based on the confirmation result from said set coin type presence confirmation section. ### Claim 2 (depends on 1) A coin bar storage according to claim 1, further comprising a storage detection section that detects an open-closed switching from an open state where said coin bar tray is drawn out from said casing into a closed state where said coin bar tray is stored into said casing, wherein said management section detects the present amount when the open-closed switching is detected by said storage detection section. ### Claim 3 (depends on 1) A coin bar storage according to claim 1, further comprising a power supply monitoring section that detects an OFF-ON switching of an external power supply from OFF to ON, wherein said management section detects the present amount when said OFF-ON switching is detected by said power supply monitoring section. ### Claim 4 (depends on 1) A coin bar storage according to claim 1, wherein said set coin type presence confirmation section includes: a weight sensor that performs detection of a weight of a coin bar set in said set section and outputs a detection result; and a confirmation section that confirms whether or not a coin bar of a set coin type is set in a detected set section where the detection is carried out, based on whether or not the detection result matches with a reference weight of a coin bar of a set coin type pre-set to said detected set section, within an allowable range. ### Claim 5 (depends on 1) A coin bar storage according to claim 1, wherein said set section is configured so that a set height of a set coin bar that is set in said set section becomes different depending on an outer diameter of the set coin bar; and said set coin type presence confirmation section includes: a distance sensor that performs detection of the set height of the set coin bar and outputs a detection result; and a confirmation section that confirms whether or not a coin bar of a set coin type is set in a detected set section where the detection is carried out, based on whether or not the detection result matches with a reference set height of a coin bar of a set coin type pre-set to said detected set section, within an allowable range. ### Claim 6 (depends on 5) A coin bar storage according to claim 5, wherein said set section has a pair of supporting faces with a shape in which a gap therebetween becomes narrower downward, and by supporting an outer periphery of the set coin bar on said supporting faces, the set height of the set coin bar is made different depending on an outer diameter of the set coin bar. ### Claim 7 (depends on 6) A coin bar storage according to claim 6, wherein said set section has a bottom face that joins bottom end parts of said pair of supporting faces, and the set height of the set coin bar is a shortest distance between the outer periphery of the set coin bar and said bottom face. ### Claim 8 A coin bar storage according to clam 5, wherein said set section has a pair of supporting points arranged with a gap which is narrower than an outer diameter of a coin bar of a coin type with a smallest diameter when seen from an axial direction of the set coin bar, and by supporting the outer periphery of the set coin bar on said supporting points, the set height of the set coin bar is made different depending on the outer diameter of the set coin bar. ### Claim 9 (depends on 1) A coin bar storage according to claim 1, wherein said set section is configured so that a set height of a set coin bar that is set in said set section becomes different depending on an outer diameter of the set coin bar, said set coin type presence confirmation section includes: a magnetic sensor that performs detection of a magnetic characteristic of the set coin bar and outputs a detection result, and a confirmation section that confirms whether or not a coin bar of a set coin type is set in a detected set section where the detection is carried out, based on the detection result. ### Claim 10 (depends on 1) A coin bar storage according to claim 1, wherein said set coin type presence confirmation section 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 in said set section spaced apart in an axial direction of the set coin bar, said set section is configured such that a set height of the set coin bar in a position of one of said magnetic sensors is constant regardless of an outer diameter of the set coin bar, while a set height of the set coin bar in a position of the other magnetic sensor is different depending on the outer diameter of the set coin bar, 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, the respective detection results are balanced, and said confirmation section confirms whether or not a coin bar of a set coin type is set in said set section based on whether or not the respective detection results from said two magnetic sensors are balanced.
