Claims

[Scope of Claim for Utility Model Registration] 1. A vehicle is equipped with a vehicle speed detector, a gear position detector that detects the gear position of the transmission, and a gear ratio memory that stores the gear ratio corresponding to the gear position, and the vehicle speed and gear position are detected. A digital engine rotation speed display device comprising an arithmetic processing circuit that retrieves a gear ratio corresponding to a gear position from a gear ratio memory, calculates and displays an engine rotation speed from a vehicle speed and a gear ratio. 2. A digital engine rotational speed display device as set forth in claim 1 of the utility model registration claim, characterized in that a microcomputer is used as an arithmetic processing circuit.
