<p>PROBLEM TO BE SOLVED: To provide an automatic correction clock for coping with a number of types of products simultaneously without requiring any complex time and labor. SOLUTION: When a switch button 21 for selecting the analog three-clock hand model of a switch group 30 for selecting a model, a switch button 22 for selecting the analog three-clock hand model, or a switch button 23 for selecting an analog two-clock hand model is on, the clock forms a parallel resonance circuit, and functions as a control circuit of an electronic wave correction clock for correcting time by receiving a standard electronic wave signal S1. On the other hand, when a switch button 24 for selecting a model as the transmitter of the switch group 20 for selecting the model, a series resonance circuit is formed, and a control circuit 14 for generating time data including a time code based on an internal clock in a specific format and transmitting it to another electronic wave correction clock is provided.</p> |
