PURPOSE: To easily confirm if the operation is being surely conducted by displaying an input state only when plural non-lock type switches are continuous ly pushed at a time.
CONSTITUTION: While oly an OFF-timer operation switch 8 and a setting switch 6 are depressed at a time, a period control part 24 continuously turns on a period 13a of a clock display part 13 based on the output sent from an installation mode discrimination part 20. At the same time, a 1st timer 21 counts the periods 13a. An instruction is given to a control part 18 after a prescribed time to be in an installation mode. In the same way, a colon control part 25 makes a colon 13b of the part 13 continuously lighted up based on the output of a store-front mode discrimination part 22 while only an ON-timer operation switch 7 and the switch 6 are depressed at a time. At the same time, a 2nd timer 23 counts. An instruction is given to the part 18 after a prescribed time to be set in a store-front mode. Then, the operations of various switches 3 to 8 are accepted and the operations are carried out based on these accepted operations.
