Filed: 1994-08-23
Abstract: PURPOSE: To reduce the height and depth size of an automatic vending machine body and to reduce shock at the time of dropping an article and shock sound corresponding to the shock by arranging an article discharging passage from a final stop position, i.e., an article discharging port, of an article carrying machine up to an article take-out port in the width direction of the machine body. CONSTITUTION: An article 13 is discharged from a tray 12a and dropped from an opening part 15a of an article sliding part 15 in an article discharging pipe 14 into the inside of the running part 15. The running part 15 is provided with a bottom 15b connected to the side face 14b of the pipe 14 and moderately inclined to an article take-out port 14a and has a rectangular cross section so that an article such as a CD and a video tape stored in a flat case can be guided. Since a video tape V1 is slid in the sliding part 15 in the state of V2→V3→V4, shock for drop is reduced and the video tape V1 is stopped on the take-out port 14a in the posture of V4. Since the bottom 15b is moderately inclined, vertical size is shortened and the take-out port 14a is arranged on a higher position as compared with a conventional one.

This forming mold F is fitted to the respectively rotatable vertical axle and horizontal axle in the furnace and heated by temp. rise therein. Both the axes are rotated. Thereby while powdery resin is moved in the cavities F3, F4, it is brought into contact with the inner walls thereof. The temp. of the inner walls of the cavities F3, F4 is raised by the above-mentioned heating of the forming mold F. Therefore powdery resin brought into contact with the inner walls becomes a molten state and furthermore transferred powdery resin is stuck thereon and melted.
