Title:
ANALOG METER DEVICE
Document Type and Number:
Japanese Patent JP2012098059
Kind Code:
A
Abstract:

To provide an analog meter device which is rationally configured as a device for indicating environment data of temperature, humidity and the like.

An analog meter device comprises a sensor 210, a dial 400, a movement 500, and controlling means 600. A driving system 510 of the movement is composed of a stepping motor 511, a deceleration mechanism 512, and a pointer pipe 513. If the amount of the environment data corresponding to a rotation angle of a pointer 310 per one step of the stepping motor is assumed as A, the pointer discretely indicates the environment data at an interval of A. The controlling means analog/digital converts the environment data of an analog signal detected by the sensor at a predetermined time interval, and controls the movement to rotation-drive the pointer to a position for indicating the converted value. Furthermore, when the value of the environment data indicated by the pointer is not deviated by A or more to the environment data before analog/digital conversion, the pointer is not rotation-driven.
