MEASURING INSTRUMENT FOR VEHICLE
Document Type and Number:
Japanese Patent JP2023080484
Kind Code:
A
Abstract:
To provide a measuring instrument for a vehicle which can display good radiation performance in spite of compact size.SOLUTION: A measuring instrument 1 for displaying shift positions of a vehicle C, comprises: a plurality of signal lines 20 which are provided corresponding to each of the shift positions; an ignition electric power source IGN which pulls up the signal lines 20; a pull-up circuit 30 which is connected between the signal lines 20 and the ignition electric power source IGN; a determination part 10 which determines the shift position on the basis of input voltage which is voltage for the respective signal lines 20; and a shift position display part which displays the shift position on the basis of determination result of the determination part 10. The pull-up circuit 30 has: first pull-up resistance groups 31 which are connected to the respective signal lines 20; and a second pull-up resistance 32 which is connected between the first pull-up resistance group 31 and the ignition electric power source ING. A resistance value of each of the first pull-up resistance groups 31 is smaller than that of the second pull-up resistance 32.SELECTED DRAWING: Figure 2
