Abstract

PURPOSE:To prevent the mutual interference of both functions and make the operation of both functions normal and accurate by always automatically locking one of sound producing function and receiving function to disable the same while the other is operating. CONSTITUTION:The output end of the control part 6 of a watch part A with alarm function is connected to the control input end of the control part 10 of a receiving function part B, and the output end of the control part 10 is connected to the control input end of the control part 6. When the set time of alarm and current time coincide, an output is sent by, e.g., comparing part 5, to the control part 6. Now, when there is no control output by the control part 10 sent to the control part 6, a sounding driving part 7 is controlled to start driving, whereby alarm is given by a specaker 8. In addition, the control part 10 controls so as not to be operated by the operation of the operation part 9. Further, when the start time of the sounding function is reached while the receiving function part B is operating, it is so controlled that the sounding function start operation upon ending of the receiving function.
