A fuel dispenser with a seismic vibration perception function includes a pump motor, a fuel feeding pump, a flow volume measuring member, a nozzle switch and a fueling control member. The fuel-feeding pump is driven by the pump motor. The flow volume measuring member measures the amount of fed fuel and outputs a flow volume pulse signal. The nozzle switch transmits a nozzle-unhooked signal and a nozzle-hooked signal. The fueling control member causes the pump motor to be 'on' and 'off' by receiving the nozzle-unhooked and the nozzle-hooked signal respectively and counting the flow volume of fuel by receiving the flow volume pulse signal. The fueling control member contains a seismic vibration perception member for perceiving vibration and transmitting a seismic vibration perception signal for suspending electric supply to the pump motor.

Fuel delivery display and control system having a dot-matrix panel on which normally a first message is indicated but when a nozzle is taken up for fuel delivery, the first message is replaced with a second message with scrolling for confirmation of no faults in the display elements whereupon the panel displays delivery information consisting of a unit volume price, a delivered fuel volume and a total price to be paid. If necessary, in advance of taking up the nozzle, a switch can be manually actuated so that the delivered fuel volume only is indicated on the panel.
