A machine particularly adapted for dispensing light items packaged in symmetrical, frustum-shaped container. The items are propelled through a tubular cartridge and individually ejected by a flow of air generated by a blower under control of a toggling dual-gate mechanism at the dispensing end of the cartridge. The dual-gate mechanism of a removable magazine grouping a number of cartridges can be selectively addressed and activated by means of a solenoid-driven cross-bar assembly.
