To realize an epoch-making conveyed object dropping device solving trouble in a feed support and a dropping process in a proper position, in the said device provided to be opposed to a rotary blade unit having a radial blade.

This conveyed object dropping device is constituted such that a rotary blade unit 3 having a plurality of radial blades 2 capable of supporting a conveyed object are provided to be laterally opposed, in the case of butt juxtaposing one radial blade 2 of this both rotary blade unit 3 mutually in a substantially horizontal condition, the fed in conveyed object is supported, and in the case of rotating the radial blade 2 of the butt juxtaposed both rotary blade unit 3 in the substantially horizontal direction respectively in an inward downward direction, the supported conveyed object can be dropped down between these rotary blade units 3. Also the device is constituted such that the radial blade 2 of both the rotary blade units 3 rotation transferred is the next is made to standby mutually in a substantially horizontal condition. Here, each radial blade 2 of the rotary blade unit 3 is constituted such that an endless belt 4 is windably and movably formed in a conveying direction, and the conveyed object fed in by operating this endless belt 4 can be conveyed.
