SUMMARY OF THE INVENTION In the above prior art,
Since the movement that drives the hour and minute hands is used to display the temperature and humidity by the hour and minute hands, only a small torque for driving the hour and minute hands is available, and therefore a relatively heavy weight is required to clearly display the temperature and humidity. Since it is not possible to use the pointing member that it has, there is a problem that the display is difficult to see from a distance. Further, when the hour and minute hands are self-propelled by using the forward / reverse rotation motor, when the motor runs away due to the influence of noise or the like and the hour / minute hands move, there is a disadvantage that the reset is not applied. In addition, since a part of the gear in the movement is read by a sensor in order to return to the display of the current time after displaying the temperature and humidity, there is a problem that there is a limitation in alignment.

Therefore, an object of the present invention is to display specific weather information by means of an analog pointing member to make it easier to see the instruction, and to obtain a large driving torque for driving the pointing member even if the pointing member is enlarged. To be able to Also,
Even when the motor abnormally rotates and the indicating member is displaced to an unexpected position, the motor is stopped by detecting this and the wasteful consumption of current is eliminated to improve the battery life.

[0005]

In order to achieve the above object, the analog weather information display device of the present invention displays specific weather information by an analog pointing member which is rotationally driven by a step motor. It is provided in
