<P>PROBLEM TO BE SOLVED: To provide a spiral transporter for powder/granular material assuring a wide degree of freedom in designing, low cost, and excellent possibility to be used in re-use and recycling. <P>SOLUTION: The spiral transporter for powder/granular material includes a rotary impeller 20 for transportation which is fitted rotatably in an outer cylinder such as a toner cartridge. A front frame 41 and a rear frame 42 are coupled together by four beams 43-46 stretching in the longitudinal direction, and further a reinforcing frame 47 is provided, and a rotary frame 40 is formed from the frames and the longitudinally stretching beams. Between the beams 43 and 44 and the ones 45 and 46, a plurality of vane pieces 31, 32, etc. are installed at a certain angle to the axial direction, and by the two bunches of vane pieces, an impeller 30 is formed to assume a spiral as a whole. All component parts including the outer cylinder (out of illustration) are formed from synthetic resin. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
