Abstract
An animal feeder for automatically feeding animals predetermined portions of food at predetermined times and calling the animals with their owner's recorded voice when the food is fed. The animal feeder comprises a body having a food container, a food remainder receiving container and a feeding mechanism. The animal feeder also includes a microcomputer for controlling the feeding mechanism, a keyboard for setting predetermined times for feeding, and a sound producing circuit for calling the animals when the food is served. The feeding mechanism is composed of a driving section for driving a trough between a food serving position and a food remainder collecting position, and a food supplying section for supplying the food by mechanical vibration. The animal feeder further comprises a sensor for detecting an animal's approach to the body of the feeder in order to stop the operation of the feeding mechanism, for the animal's own safety, when the animal approaches the body.
