Title: Clock with radio-wave correction function
Inventor: YASOOKA TADASHI
IPC: G04R20/08
Filed: 1995-01-27
Abstract: PURPOSE: To obtain a multifunctional clock which is provided with a radio-wave correction function by a method wherein the operation of a time-record reception means is permitted only when a display-content selection means selects the content of a clocking means and a function-mode operation means is stopped at this time. CONSTITUTION: When a display-mode changeover switch 51a is turned off, a display mode becomes a time-display mode, and the chronooperation of a function-mode operation means 6 is stopped. In addition, when the switch 51a is turned on, the display mode becomes a chronodisplay mode, and the operation of a time-record reception means 9 is inhibited. Consequently, during the operation of the means 9, the chronooperation of the means 6 is not performed, and the means 9 can perform a time-record operation in a stable environment comprising no noise. In addition, during the chronographic operation of the means 6, the operation of the means 9 is inhibited, and the chronographic operation is not interrupted.
