Abstract: The present invention provides a medium supplying apparatus that enables a user to easily remove medium and prevents medium from slanting or transferring improperly. The medium supplying apparatus comprises a first frame and a second frame that rotates freely with respect to the first frame. The first frame includes a first rotating section that rotates freely, a first fulcrum coupling section constructing a rotating fulcrum and a first lock coupling section. The second frame includes a pressing member, a second fulcrum coupling section constructing the rotating fulcrum by being coupled with the first fulcrum coupling section, and a second lock coupling section coupled selectively with the first lock coupling section. Because the first and second lock coupling sections are coupled selectively by relative movement, the second frame is locked or unlocked with respect to the first frame.

Abstract: A gear made of fiber reinforced resin which is capable of being increased in durability and mechanical strength, as well as gear cutting characteristics. The gear is manufactured by arranging ring-like reinforcing fiber substrates and a metal bushing in a molding die and pouring thermosetting resin into the die to impregnate the reinforcing fiber substrates with the resin. The reinforcing fiber substrates are made by winding up a cylindrical body obtained by knitting an aramid fiber yarn along a central line thereof and then forming it into a ring-like shape. The reinforcing fiber substrates are pressed in a cold die so as to approach to a shape of the molding die, to thereby be formed into a rectangular shape in cross section. Then, the reinforcing fiber substrates are received together with the metal bushing in the molding die and then the thermosetting resin is poured into the molding die.
