Clock and alarm clock corrected by radio wave with ringing function

Abstract

PROBLEM TO BE SOLVED: To provide a radio controlled clock, having alarm function, which simplifies the constitution by making the receiving function of long-wave standard waves satisfactory. SOLUTION: When an alarm setting switch 6 is at on state, the alarm time is displayed on a second hand 1c, so as to be stopped in a position corresponding to the alarm time. When 23 o'clock 57 minutes stored in a time-information reception-timing storage part 3e is reached in this situation, a reception circuit 5 starts to receive the long-wave standard waves containing time information, and the time information (a pulse signal) is detected, on the basis of the received long-wave standard waves. Since the second hand 1c is stopped, at this time, a magnetic noise generated from a second-hand drive motor 2a in the operation of the second hand 1c is not generated, and the receiving environment for the long-wave standard waves is made satisfactory, as compared with a case where the magnetic noise is generated. Since the second hand 1c is stopped in the on state of the switch 6, a detection part exclusively used to detect a state to stop the operation of the second hand is not required, and the constitution of the radio-controlled clock can be simplified.

Description

Technical field [0001] The present invention relates to a radio wave-calibrated clock and alarm clock with an alarm function, and more particularly to such a radio wave-calibrated clock and alarm clock with an alarm function. When the alarm setting switch is set to the on state, Stop the hands. Background technique [0002] Currently, a radio wave-calibrated timepiece for receiving a standard long radio wave containing time information and calibrating the display time based on the received time information has been put into practical use. [0003] In this timepiece calibrated by radio waves, a structure is provided, which has a hidden state detection section, and when the hidden state detection section detects a hidden state, it only stops the second hand at 12 o'clock. Location. According to the timepiece calibrated with radio waves, when the surrounding environment is in a hidden state, no magnetic noise is generated due to the motor driving the second hand. Therefore, in this ...

Problems solved by technology

[0004] According to the above, the second hand is stopped in order to improve the environment for receiving the standard radio long wave. However, this requires a dedicated implicit detection part to detect the stop state of the second hand. Therefore, the first problem caused is that each component has increased

[0005] In addition, when the user does not look at the movement of the clock at all, the hour and minute hands are always moving, and each pointer is performing a lot of unnecessary movements. As a result, the second problem caused is the consumption of useless work.

The second problem is not limited to clocks calibrated with radio waves, but is common to all alarm clocks
