A data carrier 2 is provided with a comparator 41, a capacitor 42, a comparator operation adjustment resistor 43, a resistance voltage divider circuit 44 and a reactive-current resistor 45. The capacitor 42 is disposed between the cathode of a photo-diode (PD) 21 and the minus input terminal of the comparator 41. The comparator operation adjustment resistor 43 is disposed between the plus terminal of a primary battery 271 and the minus input terminal of the comparator 41. The resistance voltage divider circuit 44 is constituted by a series connection of voltage dividing resistors 441 and 442. One end of the resistance voltage divider circuit 44 is connected to the plus terminal of the primary battery 271. The junction between the voltage division resistor 441 and the other voltage division resistor 442 is connected to the plus input terminal of the comparator 41.

摘要:
A display system of the present invention for a vehicle includes plural speed display areas which are capable of being simultaneously displayed, such as a first speed display area and a second speed display area, and a display controlling section causing predetermined one of speed display areas to display speed and for causing other one or more of speed display areas to display information other than speed according to necessity. This allows decrease in false recognition of the speed. With this, a display system for a vehicle can be provided, the display system being able to improve safety of driving by a user by getting rid of false recognition of speed, which is important information for safe driving.
