It is equipped with an M/PM switching means I4C and an operation time storage means +4d for storing time display data from the time display 4 in response to an operation input of the set key 10 in the time display mode.

Explain the operation.

(1) Setting the current time: For example, to set the current time to 11:58 p.m., operate the mode setter 6 to change the time display mode to the current time display mode, and the display control means +4b of the control circuit 14 As a result, the time display state of the time display 4 becomes the initial display state of midnight. When the AM/PM switch 8 is operated, the AM/PM switch 14c changes the time display state of the time display 4 to midnight. In other words, the time display on the time display 4 is incremented by 12 hours at a time.

After this increment, operate the hour setting key 2a of the time setter to increment the time by 11 hours, then use the 10 minute setting key 2b to increment the time by 50 minutes, and then use the minute setting key 2C to increment the time by 8 minutes. This completes setting the current time.

Therefore, in setting the current time in the electronic time switch of this embodiment, 12 hours of increments can be obtained by operating the AM/PM switch 8, so the 12 hours of increment operation is simplified accordingly. I will do it.

(2) Setting the operation time: For example, if you want to set the operation start time as 2:00 a.m. and the operation end time as 11:58 p.m., operate the mode setting device 6 to change the time display mode to the operation time display mode. At the same time, while looking at the time display 4, the user operates the time setting device 2 to set the time display on the time display 4 to 2:00 a.m. as shown in FIG. 4A.

In this case, the operation input of the time setting device 2 and the mode setting device 6 is given to the time data output means 14a and the display control means 14b of the control circuit 14, so that the time display state of the time display 4 is set to 2 AM. It's time. When the operation is completed after 2:00 a.m., when the set key 10 is operated, the time data of the start of the operation at 2:00 a.m. displayed on the time display 4 is stored and determined in the operation time storage means 14d.

After this confirmation, if you operate the AM/PM switch 8,
The time display state of the time display 4 is set to 2:00 pm by the M/PM switching means 14c as shown in FIG. 4B. In other words, A.M.
The /PM switching means 14c advances the time display of the time display 4, which is in the display state of @2:00 p.m., by 12 hours to 2:00 p.m. in response to the manual operation of the AM/PM switch 8.

Then, the time setting device 2 is operated from this display state of 2:00 p.m. toward the operation end time of 11:58 p.m. In the same manner as described above, the operation input of the time setting device 2 is changed to the time. The data is applied to the data output means 14a. As a result, the time data output means 14a displays the time on the time display 4 as 11:58 p.m. as shown in FIG. Memorized and confirmed.

Therefore, in setting the operating time of the electronic time switch of this embodiment, 12 hours of increments can be obtained by operating the AM/PM switch 8, so that the 12 hours of increments can be made that much easier. become.

(Effects of the Invention) As is clear from the above explanation, according to the present invention,
Just by operating the AM/PM switch, when the time display on the time display shows AM, it will read PM, and when it shows PM, it will read AM. Since it can be performed all at once with a simple operation, the troublesome operation required in the conventional example can be eliminated.
