Claim Text:
1. A wire reel which is mountable to a reinforcing bar binding machine, the wire reel comprising: cylindrical hub portion configured to allow a wire to be wound on the hub portion; a pair of parallel flanges overhanging radially outward from first and second axial ends of the hub portion; a side wall that is provided radially inside of the hub portion and in-between the pair of parallel flanges and intersects with an axial direction of the wire reel; a plurality of light-transmitting portions that are provided in-between the pair of parallel flanges and radially inside of the hub portion, the plurality of light-transmitting portions provided on the side wall and transmitting light through inside the hub portion; a plurality of information detection regions that are configured to be detected by the reinforcing bar binding machine and that are provided on the side wall in-between the pair of parallel flanges, wherein the plurality of information detection regions are formed with at least one light-transmitting portion, and the plurality of light-transmitting portions are configured to allow the reinforcing bare binding machine to identify a type of the wire reel based on a number of the light-transmitting portions provided on one of the information detection regions being different from a number of the light-transmitting portions provided on another of the information detection regions such that an interval between one light-transmitting portion and one adjacent light-transmitting portion is different from an interval between the one light-transmitting portion and another adjacent light-transmitting portion, in a circumferential direction about the side wall.
