Claims

[Scope of utility model registration request]

The top surface of the bottom plate of the supply container is a tapered surface that slopes downward toward the center of the bottom plate, and the top surface of the rotor, which is placed on the bottom plate and is driven to rotate in one direction, slopes downward toward the outer periphery of the rotor. A drug entry path is formed between the outer periphery of the lower surface of the rotor and the upper surface of the bottom plate, and a tapered surface that matches the tapered surface of the bottom plate is provided on the inner periphery of the lower surface of the rotor. A plurality of pockets are formed at equal intervals in the circumferential direction of the pump, a supply port is provided in the bottom plate to match one of the pockets, and a thin wall is provided to cover the upper opening of the pocket that is matched with the supply port by rotation of the rotor. In a quantitative drug supply device in which a thick tongue piece is provided inside a supply container, a supply path is provided continuously to the supply port, and a photodetector is installed in the supply path to detect the drug passing through the inside. 1. A fixed-quantity supply device for a drug, characterized in that a required number of photodetectors are arranged horizontally.
