Abstract
PURPOSE: To facilitate the reading of a vehicle speed and enable the auditory confirmation of the speed, by performing indication by an output resulting from the comparison of a speed signal with a set reference of each speed stage.
CONSTITUTION: When a switch 4 of a speed indicator 2 is operated by a an operator, a reference signal 4a corresponding to one of speed stages each for a speed range of 5km/h is selected and a speed indication lamp of a lamp unit corresponding to the reference signal 4a is lighted on. The selected signal 4a is compared with a speed signal from a speedometer 1 or the like by a comparison circuit 3. A lamp 7-1 and a buzzer 8-1 or another lamp 7-2 and another buzzer 8-2 are turned on through a driving circuit 5 made of gates or the like, depending on which of a vehicle speed and a selected stage speed is higher. This results in facilitating the reading of the vehicle speed and enabling the auditory confirmation of the speed.
