When switching from the normal time display to the specific function display, the display changeover switch 19 is operated to trigger the flip-flop 21, which is an inverting circuit, to change the flip-flop 21 from the reset state to the set state. By switching, the count contents sent out from the normal time counting section 12 are prohibited by the AND circuit 13, and the count contents sent out from the specific function counting section 17 are supplied to the display section 15 via the AND circuit 18 and the OR circuit 14. Then, a specific function is displayed. The selection of the specific function at this time is performed by setting the function selection switch 24, and the function selected by the function instruction signal obtained by the function selection switch 24 is displayed on the function instruction display section 25. The function control gate group 26a to 26 selects the function whose function instruction signal is given to the function counting control section 16.

In addition, the control switch 20 is operated to control the settings of specific functions, change (correct) the contents of the normal time, etc., and when the control switch 20 is operated when the normal time is displayed, the AND gate 22 is operated. When opened, it is possible to change the contents such as time adjustment, and when the control switch 20 is operated when a specific function is displayed, the AND gate 23 is opened and it is possible to set the specific function. However, in the conventional multi-function electronic timepiece device having such a configuration, one specific function counting section 17 is configured to perform counting operation of the selected specific function. However, it was not possible to count multiple types of specific functions in parallel and selectively display one of them.

Therefore, a plurality of specific function counting units are provided, and a plurality of switches are provided corresponding to each function selection unit to perform multiple types of specific function counting operations in parallel. The contents of the function counter must be displayed, and the structure is complicated due to the large number of switches, making it impractical, especially for small devices such as electronic wristwatches.
