Abstract
Abstract A slot machine reel comprises a cylindrical body having symbols on the periphery thereof and a reinforcing plate fixed to the cylindrical body and coupled therethrough to a drive shaft of a motor. The cylindrical body has a bridge fixed thereto and including arms formed to extend toward the central portion of the body, and the reinforcing plate is fixed to the bridge. The cylindrical body and bridge are preferably plastic moldings so as to make the reel light in weight, and the reinforcing plate is preferably a metal plate such as aluminum so as to obtain a firm coupling to the drive shaft of a motor. The cylindrical body is comprised by two short cylindrical frames having tongues that extend toward each other and to which a belt-type sheet bearing printed symbols is secured. The surfaces of the tongues to which the sheet is secured are set radially inwardly the thickness of the sheet, so that the peripheries of the frames and the sheet are flush with each other.
