Zusammenfassung:The present invention is directed to an electric type speed meter which comprises a pulse generating means for generating a pulse signal corresponding to a vehicle speed. A control circuit means counts the number of output pulses of the pulse generating means during predetermined time intervals and discriminates between a positive and negative difference between the number of pulses counted during a predetermined time interval and the number of pulses counted in a preceding time interval. The control circuit means generates a pulse signal corresponding to the difference therebetween. A pulse motor driving circuit applies the output of the control circuit means to a pulse motor for controlling the pulse motor in either a forward or reverse direction. An indicator means is operable in response to the pulse motor for indicating a speed corresponding to the speed thereof.
