An electronically-controlled fluid dispenser which houses a replaceable self-venting, self-priming plump and fluid container and contains a rotary motor for automatically operating the pump in response to an optically-detected infrared signal. The infrared signal is generated with a predetermined waveform which is detectable by a receiver so as to avoid extraneous signals. The rotary motor operates the pump through an eccentric cam directly mounted upon the pump dispensing plunger to cause direct linear motion. The dispenser is designed for battery operation.

An electronically-controlled fluid dispensing system comprising: a housing; a flexible container mounted in said housing for storing fluid to be dispensed from said housing; a self-priming pump having a reciprocating pump head mounted upon said container and spout means for discharging fluid from said container upon depression of said pump head; a rotary motor mounted in said housing and having a rotatable output drive shaft; a cam eccentrically mounted upon said output drive shaft with said cam having a cam shaft juxtaposed in physical contact against said pump head; and an electrical control drive circuit for operating said rotary motor over a short, predetermined time interval upon detection of an optical signal of predetermined waveshape, with said drive circuit including means for emitting an optical signal external of said housing and of short duration with a predetermined wavelength in the infrared spectrum and circuit detector means for detecting an optical signal reflected back to said housing from an object placed in the path of said emitted signal, with said circuit detector means being responsive only to an optical signal in the infrared spectrum and only when said signal is of a predetermined configuration, means responsive to actuation of said circuit detector means for generating a timed control signal, and means for applying power to said rotary motor in response to said timed control signal.
