DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analog weather information display device and a mechanical timepiece provided with the device.

[0002]

2. Description of the Related Art Conventionally, as a means for displaying basic weather information such as temperature and humidity in an analog manner, a time display device of a clock is used, and a temperature scale and a humidity scale are formed by arranging the time scale on a dial. When the temperature and humidity buttons are pressed while the hour and minute hands are displaying the current time, the hour and minute hands will self-run, indicating the temperature with the long hand and the humidity with the short hand, and two more hands. There is a configuration in which the pointers overlap to display the comfort level, and thereafter return to the display of the current time again.

[0003]

In the above prior art,
Using a movement to drive the hour and minute hands, the temperature and humidity are indicated by the hour and minute hands, so that only a small torque for driving the hour and minute hands is available. Since the pointing member cannot be used, there is a problem that the display is difficult to see from a distance. In addition, when the hour / minute hands are self-propelled using the forward / reverse rotation motor, there is a disadvantage that the motor does not run away due to the influence of noise or the like and the hour / minute hands move, so that resetting is not performed. Further, in order to return to the display of the current time after the display of the temperature and the humidity, since a part of the gears in the movement is read by the sensor, there is a problem that the alignment is limited.

Accordingly, an object of the present invention is to display specific weather information by an analog indicating member so as to make it easier to see the instruction, and to obtain a large driving torque for driving the indicating member even if the indicating member is enlarged. To be able to Also,
Even when the motor is abnormally rotated and the indicating member is displaced to an unexpected position, this is detected and the motor is stopped, so that useless current is not consumed and the battery life is improved.

[0005]

In order to achieve the above object, an analog weather information display device according to the present invention displays specific weather information by an analog pointing member which is driven to rotate by a step motor. Provided in the
The stepping motor is provided so that a driving signal is supplied by a control circuit which operates in response to an output of a sensor for detecting specific weather information, and when the indicating member is displaced to an unexpected position beyond a predetermined display range. The control circuit is provided so as to stop the supply of the drive signal to the step motor when the limit switch is operated.
