In addition, it has a sleep timer function that turns off the external power supply circuit after a preset time elapses from sleep start, a counter function that calculates the elapsed time from counter start, and a preset and memorized predetermined time. It has a timer function that turns on and off the external power supply circuit after the elapsed time has elapsed, and furthermore, this timing control LSI 6 is preprogrammed with an operation control function that selects various functions as described above and controls their operations. This operation control function receives the operation output from the operation unit 5 and controls each function of the timing control LSI 6 according to a preset program. Figure 2 shows a circuit configuration diagram when a 1-chip microcomputer is used for the timing control device LSI 6. In the figure, 7 is a power supply circuit section, and 8 is a program for setting channels for timer operation provided in the operation section 5. Switch SW ₁ …

are adapted to perform respective displays in response to control signals from the timing control LSI 6.

FIG. 3 is a diagram showing a configuration in which the functional operations of the timekeeping control LSI 6 are divided into blocks.The clock function section 17 calculates the current time by receiving and counting the clock of an oscillation circuit 30 using an externally provided crystal oscillator. In normal times when the current time display setting switch 3 is turned on and the current time display mode is set, the display on the display device 2 is controlled by the output of the clock function section 17 via the display control function section 18. Part 1
3 and 16 are driven, and the display section 13 displays "hour" and "time".
In the “minute” display area 13a, the “hour” of the current time,
The "minutes" and "seconds" of the current time are displayed in the "seconds" display section 13b, and the "day of the week" of the current day is displayed on the display section 16, for example, "SUN" in FIG.
characters are displayed. At this time, the display section 14 displays a mark 14a indicating that the current time is being displayed, and the display section 15 displays characters 1 indicating the channel.
5 ₁ to 15 ₄ are displayed. When the time adjustment setting switch 19 of the operation section 5 is turned on, the operation control function section 20 switches to the time adjustment mode, and the display section 14 flashes a mark 14c indicating that it is in the time adjustment mode. At the same time as the display, the driver circuit section 8 is driven via the display control function section 18, and the light emitting element _L6 is provided at the upper part of the arrangement of the "day of the week" set switch 21 and the cancel switch 22 provided on the operation section 5. “Hour” setting switch 23, “minute” setting switch 2
The light emitting elements L ₇ provided at the middle upper part of the arrangement of 5 emit light respectively. This illumination allows you to see at a glance which switches are required to set the time. When the "day of the week" set switch 21, "hour" setting switch 23, "minute" up setting switch 24, or "minute" down setting switch 25 is operated, the "day of the week" of the clock function section 17 is operated.
The counter, "hour" counter, and "minute" counter are counted up or down by the clock of the oscillation circuit 30, and when the display on each display section 16, 13 reaches the predetermined display content to be set for the day of the week and the time, each of the above-mentioned When the operation of switch 23, 24 or 25 is stopped, the time and day of the week contents are changed to “day of the week,”
The contents of each "minute" counter will be adjusted to the time, and when the zero reset switch 26 of the operation unit 5 is turned on, the "second" counter will be set to "00".
When the zero reset switch 26 is turned off and the zero reset switch 26 is turned off, the timekeeping operation starts from that point, and when the current time display setting switch 3 is turned on, the mode returns to the above-mentioned current time display mode. Incidentally, during this time setting, the output of the clock function section 17 which is currently setting the time is displayed on the display sections 13 and 16.

Next, the timer setting function section 27 is a circuit section that sets and stores the time at which the timer operation should be performed.When the timer set switch 28 is turned on, the timer setting function section 27 enters the timer set mode, and by the operation of the operation control function section 20, Each character 15 ₁ to 15 ₄ indicates a set channel of the display unit 15 via the display control function unit 18
are displayed blinking, and at the same time, a mark 14b indicating that the timer set mode is set on the display section 14 is displayed blinking (FIG. 4a). In addition, the driver circuit section 8 is driven, and the light emitting elements _L4 to _L8 provided corresponding to the switches required for setting the timer operation emit light, and among them, the program switch _SW1 for channel setting... The light emitting element _L4 provided at the upper center blinks to indicate the first operation order. Next, we will explain the setting procedure for turning on the output of outlet 10a at 12:58 a.m. on Sunday and turning it off at 2:00 p.m. on Sunday in channel No. 1. First, when program switch SW ₁ is turned on, the display section 13 will be turned on. The display on the "hour and minute" display section 13a becomes "0:00". It should be noted that when the timer set mode is set, the displays on the display sections 13 and 16 are off.

Now, at the same time as the above display, as shown in FIG. 4b, "A" and "B" indicating the outlets 10a and 10b on the side of the character ₁₅₁ corresponding to the channel setting NO1 on the display section 15 are displayed blinking. The light emitting element L5 provided between the outlet designation switches 31a and 31b of the operating section ₅ is driven to blink, indicating that the operating procedure has shifted to outlet designation. At this time, since the channel setting has been completed, the characters 15 ₁ to 15 ₄ and the light emitting element L ₄ continue to blink, resulting in a continuous display state. Further, the characters "SUN" are displayed on the display section 16, and the characters "ON" are displayed on the display section 15. Next, when the outlet designation switch 31a is turned on, the fact that the outlet designation switch 31a is turned on and the outlet 10a is designated is written and stored in the memory section of channel No. 1. Here, a pair of storage units for each channel is provided corresponding to each outlet 10a, 10b, and it is possible to store an ON operation setting time and an OFF operation setting time for each outlet 10a, 10b, respectively. I'm starting to be able to do it. Now, the outlet designation switch 31a mentioned above
At the same time, as shown in FIG. 4c, the display section 16
The word "SUN" will be displayed blinking, and
The light emitting element _L6 provided at the intermediate upper position between the day of the week set switch 21 and the cancel switch 22 is driven to blink, indicating that the operation procedure has moved to day of the week setting. Now, when you turn on the cancel switch 22 in the above condition, the blinking of the above-mentioned characters stops and disappears, and the blinking moves to the letters of the next day of the week.The characters that blink each time you turn on the cancel switch 22 are When the character of the day of the week that you want to set, for example, "SUN" is blinking, if you turn on the set switch 21, it will start blinking. changes to lighting, the day of the week setting is written and memorized in the memory, the blinking moves to the next "MON", and at the same time the blinking of the last character "SAT" is canceled, the next blinking of light emitting element L ₆ lights up continuously. At the same time, the light emitting element L ₇ is driven to blink, and the "hour, minute" display section 1 of the display section 13 changes.
The display 3a blinks as shown in FIG. 4d, indicating that the operating procedure has moved on to time setting. Here, in the same way as setting the current time, turn each switch 23 to 25.
Operate to set the desired time to turn on. At the same time as this setting starts, the blinking of the light emitting element L ₇ changes to continuous lighting, and the light emitting element L ₈ provided above the off setting switch 33 is driven to blink, and the display unit 1
At step 5, the character corresponding to "OFF" flashes, requesting that the off setting switch 33 be turned on (FIG. 4e).
When the above-mentioned time setting is completed and the off setting switch 33 is turned on, the word "OFF" changes to a continuous display, the light emitting element _L8 is lit continuously, and the display section 13 again shows "hour". , minutes" display portion 13a is driven to blink as shown in FIG. 4f, and the light emitting element _L7 is driven to blink. Then, if you set the off time in the same way as the on time setting,
The display in the "hour and minute" display section 13a becomes a continuous display, and all of the light emitting elements _L4 to _L8 are driven to a continuous lighting state (FIG. 4g). This completes the timer setting for channel NO1. If you wish to continue setting the timer, turn the program switches SW ₂ , SW ₃ ,
If you turn on the program switch of the channel you want to set in SW ₄ , the same display operation as when setting the timer described above will be performed, and you can continue to set the timer.

Next, if you want to check the program settings for each channel while in current time display mode,
When you turn on the program switch SW ₁ of the channel you want to check, for example NO1, the operation control function unit 20 sets a program confirmation period in which the timer operation information of channel NO1 is displayed with priority over the current time. be. That is, the timer on time and timer off time stored in the storage section of the channel of the timer setting function section 27 are read out, and are alternately displayed on the display section 13a of the display section 13 of the display device 2 via the display control function section 18. It is displayed for a predetermined period of time (for example, 2 seconds). This display is alternately repeated every 2 seconds while the program switch SW ₁ is turned on, and after the operation is canceled, the current time is automatically displayed by the action of the operation control function section 20 after the timer off time is displayed. I will be going back. By the way, during this confirmation, the contents of the program settings can be changed and corrected, and Fig. 5 is a specific circuit diagram corresponding to channel No. 1 for explaining the principle of this change and correction, and in the example, it is programmed by software. . Now, Figure 5: 48 in the circuit
is a key switch, and this key switch 48 controls the operation of the timer setting function unit 27 so that the timer is turned on, for example, 5 seconds before the set timer-on time, taking into consideration the startup time of the recorder used as an external load. This is for setting, and is set by input operation when setting the program as necessary. This setting is applied to display section 1 of display device 2.
It is displayed as 5 characters "CUE". By the way, the timer setting function section 27 for each channel is provided with an outlet designation memory 60 and a queue memory 61, respectively, and when setting a program, the J-K flip-flops 62 and 6 provided at the front stage of each channel are used.
Each time the Q outputs of 3 and 64 are inverted, settings and cancellations are written and stored alternately. Each J
-K flip-flops 62, 63, 64
AND gates 65, 66, 67 at the clock input terminal
Output terminals are connected to one input terminal of each outlet designating switch 31a, 31b, key switch 48.
However, the Q output of the R-S flip-flop 68 is connected to the other input terminal. And R-S
A program switch SW ₁ is connected to the S terminal of the flip-flop 68. Of course, these circuits are configured for each channel.

For example, when the program switch _SW1 of channel No. 1 is turned on, the R-S flip-flop 68 is set and the Q output is set to the "H" level. With this "H" level setting, the outlet designation switches 36a, 36b,
When the key switch 48 is turned on as required, the corresponding J-K flip-flop 62,6
The Q outputs of 3 and 64 are inverted, and each memory 60 and 61
It is possible to change the contents of the memory.

Now, when the program switch SW ₁ is turned on to check the program setting contents of channel No. 1 set as described above, the memory 60 built in the timer setting function section 27 is activated by the operation control function section 20 as described above. Then, the contents of the queue memory 61 are read out, and the outlets 10a, 1
Each setting content of 0b is input to the decoder 69 as a 2-bit signal, decoded, and displayed on the display section 15 of the display device 2 via the display control function section 18.
The letter "A" indicating the outlet 10a is displayed on the side of the letter ₁₅₁ corresponding to the stored content. On the other hand, since the queue setting has not been made, no output is generated from the queue memory 61, and the characters 14c indicating the queue setting are not displayed on the display section 14. Next, during this confirmation, if you want to program the outlet 10b and release the outlet 10a, first turn on the outlet designation switch 31a, and an "H" level signal will be sent to the JK flip-flop 62 via the AND gate 66.
When input to the Clock input terminal, its Q output is inverted.
This reversal causes outlet 10 of memory 60 to
For example, if the memory content of the storage area related to a is “01”
is rewritten to "00", and the "A" displayed on the side of the character 151 corresponding to channel No. ₁ , which was being displayed through the decoder 69 and the display control function section 18, disappears. Furthermore, when the outlet designation switch 31b is turned on, the Q output of the J-K flip-flop 63 is inverted in the same way as the change described above, and the stored content of the storage area related to the outlet 10b of the memory 60 is changed from "00" to "01". Outlet 10b is connected to the side of character ₁₅₁ corresponding to channel NO1 on display section 15 via decoder 69 and display control function section 18.
The character "B" corresponding to the character "B" will be displayed.
In this way, the setting contents can be similarly changed by turning on the key switch 48, and each time the switch 31a, 31b, 48 is turned on, the stored contents of each memory 60, 61 can be set or reset. You can modify and change it alternately.

In the above embodiment, when the program switch is first turned on, a set signal is input to one input terminal S of the R-S flip-flop 68 and the program is set, and the program is confirmed until a reset signal is input from another input terminal R to the other input terminal R. A period is set and the settings can be modified during that period, but if the reset is applied by turning off program switch SW ₁ , the settings can only be changed during the period when the program switch is turned on. This is possible.

Next, the timer setting function section 27 operates when the current time output from the clock function section 17 reaches a predetermined time on one of the set days of the week stored in the timer setting function section 27, and the timer operation specified at this timer setting time is activated. The load control relay circuit sections 9a and 9b are controlled to operate by determining whether the relay is on or off and controlling the load control relay circuit sections 9a and 9b via the external load control function section 20.
Operate Rya, Ryb and outlet 10a, 10
It turns on and off the external power supply circuit connected to b. 32a and 32b are outlet 10
This is the load of the external power supply circuit connected to terminals a and 10b, respectively. The sleep timer function section 34 has a built-in counter for measuring time, receives the clock from the oscillation circuit 30, performs a count-up operation, and turns off the external power supply circuit when the count-up is completed.
Manual switch while this sleeve timer is operating
By pushing SWa in, you can return to the state before the operation started.

When the counter switch 43 is pressed, the counter function section 42 enters the counter function mode. When the counter switch 43 is pressed, the counter function section 42 enters the counter function mode.
The time counting operation starts at the same time as the pressing operation.
“Minutes” of elapsed time from this start timing
and "seconds" are displayed in the "hour, minute" display area 13a. When the start/hold switch 44 is pressed and operated again, the time counting operation is stopped at that operating timing, and the "hour, minute" display section 13a displays the elapsed time until the stop timing, and is then reset. When the switch 45 is operated, the time counting operation is reset and "0:00" is displayed again. Here, the time counting operation will be performed for a maximum of 99 minutes and 59 seconds. It can also be used together with the sleep timer function section 34. SWb in Figure 1
is a manual switch that manually turns on and off the external load power supply circuit connected to the outlet 10b, and _L3 is a light emitting element that displays its operation;
Reference numeral 47 is a set switch for operating the timer according to the above-mentioned timer settings.During setting, the light emitting element _L1 on the top lights up, and while canceling the setting, the light emitting element _L1 goes out and the timer does not operate. Show that it is not.

The present invention is constructed as described above, and includes a program switch for setting channels of a plurality of programs, an information input switch for inputting information including an outlet connected to an external electric circuit and a timer operating time, and a switch for inputting information including the timer operation time. A timer setting function section to be stored and a program confirmation period for displaying the timer operation information of the corresponding channel with priority over the current time when the program switch is turned on when in the current time display mode are set, and the program confirmation period is being set. The outlet is equipped with an operation control function section that changes and corrects the stored contents of the previous outlet information when the outlet information input switch is turned on. It can be corrected by simply inputting the information, and since changing the outlet used can partially correct the program settings, it saves the trouble of clearing all the program contents such as operation time and setting them again, and anyone can handle it. It has the effect of being easy to use.
