Each display is performed in response to a control signal from the LSI 6.

FIG. 3 is a drawing showing a configuration in which the functional operations of the timekeeping control LSI 6 are divided into blocks.The clock function section 17 receives and counts the clock of an oscillation circuit 30 using an externally provided crystal oscillator to calculate the current time. In normal times when the current time display setting switch 3 is turned on and the current time display mode is set, the output from the clock function section 17 controls the display section of the display device 2 via the display control function section 18. 13,1
6 are driven, and the display unit 13 displays "hours" and "minutes".
The “hour” and “minute” of the current time are displayed in the display part 13a.
However, the "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, in the case of FIG. 1, the characters "SUN" are displayed. At this time, the display section 14 displays a mark 14a indicating that the current time is being displayed, and the channel display section 15 displays characters 15 ₁ to 15 ₄ indicating channels. When the time setting switch 19 of the operation section 5 is turned on, the operation control function section 20 switches to the time setting mode, and the display section 14 shows a mark 14c indicating that it is in the time setting mode. At the same time as the blinking display, the driver circuit section 8 is driven via the display control function section 18, and the light emitting element L ₆ provided at the middle upper part of the "day of the week" set switch 21 and cancel switch 22 provided on the operation section 5 is activated. ,
The light emitting elements _L7 provided at the upper middle of the arrangement of the "hour" setting switch 23, "minute" up setting switch 24, and "minute" down setting switch 25 are made to emit light, respectively. This light emission allows you to see at a glance which switches are required for adjusting the time. and “day of the week” set switch 21,
When the "hour" setting switch 23, "minute" up setting switch 24, or "minute" down setting switch 25 is operated, the "day" counter of the clock function section 17,
The "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 a predetermined display content for setting the day of the week and the time, each switch 23 is turned on. , 24 or 25, the contents of the time and day of the week will be displayed, such as "day of the week", "hour",
The contents of each "minute" count 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 is controlled by the operation of the operation control function section 20. , the characters 15 ₁ to 15 ₄ indicating the set channels on the channel display section 15 are displayed blinking via the display control function section 18, and at the same time, the mark 14b on the display section 14 indicating that the mode is in the timer set mode is displayed blinking. (Figure 4a). Further, when the driver circuit section 8 is driven, 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 setting the channel emits light. The light emitting element _L4 provided at the upper center of the screen blinks, indicating 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 "hour", "minute"
The display on the display portion 13a becomes "0:00". Furthermore, when the timer set mode is set, the display section 13
The display portions 16 and 16 are off.

Now, at the same time as the above display, as shown in FIG. 4b, the outlet 10a on the side of the character ₁₅₁ corresponding to channel setting No.
"A" on the outlet display section corresponding to 10b,
"B" is displayed blinking and the light emitting element L5 provided at the middle upper part of the outlet designation switches 31a, 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 stop blinking, 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 channel display section 15. Next, when the outlet designation switch 31a is turned on, the channel
Outlet designation switch 31a is placed in the memory section of NO1.
It is written and stored that the outlet 10a has been designated. Here, a pair of storage units for each channel is provided corresponding to each outlet 10a, 10b.
The on-operation setting time and the off-operation setting time can be stored once for each unit 10b. Now, at the same time as the aforementioned outlet designation channel 31a is turned on, the word "SUN" flashes on the display section 16 as shown in FIG. The light emitting element _L6 is driven to blink, indicating that the operation procedure has moved on to setting the day of the week. 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 If you turn on the cancel switch 22 and turn on the characters "SAT", it will move to the first character "SUN", so if you turn on the set switch 21 when the character of the day of the week you want to set, for example "SUN", is blinking. , the blinking will change to a steady light, and the day of the week setting will be written to the memory and stored.
When the blinking moves to the next "MON" and the blinking of the last character "SAT" is canceled, the blinking of light emitting element L ₆ changes to continuous lighting, and the light emitting element L ₇ is driven to blink, and the display section 13. "Time",
The display in the "minute" display area 13a is driven to blink as shown in FIG. 4d, indicating that the operating procedure has shifted to time setting. Here, in the same way as when setting the current time, each switch 23 to 25 is operated to set a desired time to turn on the switch. As soon as this setting starts, the flashing of light emitting element L ₇ changes to continuous lighting, and the off setting switch 3
The light emitting element _L8 provided on the upper part of the switch 3 is driven to blink, and the characters corresponding to "OFF" blink on the display section 15, 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,
As the character "OFF" changes to a continuous display, the light emitting element _L8 is lit continuously, and the display of the "hour" and "minute" display portions 13a of the display section 13 is driven to blink again, and the light emitting element _L7 is driven to blink. When the OFF time is set in the same manner as the ON time, the hour and minute display portions 13a display continuously, and all of the light emitting elements _L4 to _L8 are driven to a continuous lighting state. At this point, the timer setting for channel NO1 is completed. If you wish to continue setting the timer, turn on the program set switch for the channel you want to set among program switches SW ₁ , SW ₂ , and SW ₄ after completing the above-mentioned OFF time setting, and the display operation similar to that when setting the timer described above will occur. The timer settings can then be made.

If you wish to return to the current time display after completing the timer setting, turn on the current time display setting switch 3 to return to the current time display mode and display the current time as described above.

Therefore, the timer setting function section 27 is the clock function section 1.
It operates when the current time of the 7 output reaches a predetermined time on one of the set days of the week stored in the timer setting function section 27, and determines whether the specified timer operation is on or off at this timer setting time, and then outputs an external signal. The load control relay circuit section 9a is controlled to operate via the load control function section 29 (in the above case, the outlet 10a is set to operate); Activate relay Rya and connect outlet 10a
It controls the on/off of the external power supply circuit connected to the 32a and 32b are outlet 10a,
These are the loads of the external power supply circuits connected to the respective terminals 10b. FIG. 5 shows a detailed circuit diagram of the timer setting function section 27. As shown in FIG. In the figure, 60 is a "day of the week" memory for storing the "day of the week", 61 is an "hour" and "minute" memory for storing "hours" and "minutes", and 62 is an outlet 10.
These memories 60 to 62 are provided for channels NO1 to NO4 to which each program is set, and each memory 61 to 62 shown in FIG. Shows what corresponds to NO1. 63 and 64 are comparators, respectively, and the comparator 63 generates an output when the stored content of the "day of the week" memory 60 and the count of the "day of the week" counter section of the counter 17a of the clock function section 17 match, and The comparator 64 is the “time” of the counter 17a,
It generates an output when the count of the "minute" counter unit matches the stored contents of the "hour" and "minute memory 61", and the output of the comparator 64 functions as a timer on or timer off timing signal for external load control. On the other hand, the output of the comparator 63 is calculated by an AND gate 65 using a 1 Hz signal obtained by frequency-dividing the clock of the oscillation circuit 30 by the counter 17a. 66 is a decoder, and this decoder 66 stores the stored contents of the storage memory 62 in correspondence with the respective outlets 10a and 10b.
For example, the 2-bit signal read from the outlet 2 is decoded, and if the outlets 10a and 10b are specified, an "H" level signal is output separately for each. These signals are passed through AND gates 67a and 67b, respectively, to the AND gate 65.
is calculated with the output of And gate 67a, 67
The respective output signals of b are input to the display control function section 18, and are sent via the display control function section 18 to characters 15 1 to ₁ indicating the channel NO of the display section 15 of the display device 2.
The letters "A" and "B" on the outlet display sections corresponding to 10a and 10b designated on the sides of ₅₄ are displayed blinking at 1 Hz.

However, as mentioned above, if outlet 10a is programmed in channel NO1,
When the set day of the week arrives, the output of the comparator 63 opens the gate of the AND gate 65, and 1 Hz signals are input to the AND gates 67a and 67b, respectively. At this time, since the outlet 10a is specified as described above, the output of the dacoder 66 is set to "H" level only on the AND gate 67a side, so the 1 Hz signal is output to the display control function section 18 via the AND gate 67a. However, the display control function section 18 adds the letter "A" to the side of the channel No. 1 letter 151 displayed on the display section ₁₆ of the display device 2.
The display blinks at Hz, and this display notifies you that it is the day the program is set. The sleep timer function section 34 in FIG. 3 has a built-in counter for time measurement, receives a clock from the oscillation circuit 30, performs a countdown operation, and turns off the external power supply circuit when the count ends. Next, the operation of this sleeve timer function section 34 will be explained based on FIG. 3. Now, in the current time display mode shown in FIG. A control signal is transmitted to the load control relay circuit section 9a (in the embodiment, one outlet 10a is
(set to be under the control of the sleep timer), the relay Rya is activated, and the load 32a of the external charge circuit connected to the outlet 10a is turned on. At the same time, the driver circuit section 8 is controlled through the display control function section 18, and a manual switch provided corresponding to the outlet 10a is activated.
Light up the light emitting element L ₂ placed on the top of SWa,
Indicates that load 32a connected to outlet 10a is on. At the same time, the output of the "second" counter section is no longer output to the display device 2. Then, the output of the sleep counter is displayed on the display section 13 of the display device 2.
It will be output as a drive signal for the "seconds" display part 13b of the clock. First, an output of "00" is generated, and when the output continues for several seconds, it receives the clock and performs a subtraction counting operation. At the start, the "second" display section 13b shows "99" minutes, and at the same time, the above-mentioned ON control of the outlet 10a is performed. When the sleep switch 3 is continued to be pressed, the above-mentioned subtraction counting operation is carried out at high speed, and the display on the "second" display section 13b is gradually decreased from "99" to "98" to "97"...etc. When this display time reaches the desired sleep setting time, when the sleep switch 4 is released from the pressed state, the sleep time is set and the sleep time measuring operation is started. After this, the sleep counter of the sleep timer function section 34 sequentially subtracts 1 from the set number of sleep hours at fixed time intervals (1 minute intervals) until the content of the sleep counter reaches "00". At this point, the output of the sleep counter is transmitted to the external load control function section 29, and the load control relay circuit section 9a operates to drive the relay Rya and turn off the external power supply circuit of the outlet 10a. At the same time as this turning off, the light emitting element L ₂
Turn off the light. At the same time as the sleep switch 4 is turned on, the word "Sleep" is displayed on the "second" display section 13b via the display control function section 18.
By the way, when the sleep counter described above finishes counting, the "second" display section 13b of the display section 13 of the display device 2 is switched and driven by the contents of the "second" counter section of the clock function section 17 via the display control function section 18. Therefore, the "second" display portion 13b will display the "second" of the current time. To check the "seconds" of the current time while the sleep timer function section 34 is operating, turn on the current time display setting switch 3, and the contents of the "seconds" counter section of the clock function section 17 will be displayed in the display control function section 18. It can be displayed on the "seconds" display portion 13a of the display section 13 via the "seconds" display section 13a of the display section 13. After this, if you wish to view the remaining sleep time, press the sleep switch 4 to switch to the sleep mode in which the count contents of the sleep counter are displayed in the "second" display section 13a.

If you wish to reset the operation of the sleep timer function section 34, press the manual switch SWa and the sleep counter of the sleep timer function section 34 will be reset through the operation control function section 5.
In the same way as at the end of counting, the display contents of the "second" display part 13b are switched to the current time, the external power supply circuit of the outlet 10a is turned off, the light emitting element _L2 is also turned off, and the state before the sleep timer function part 3 starts operating is restored. will return to. Counter function section 4
2 enters the counter function mode when the counter switch 43 is turned on, and the display control function section 18 resets the "hour" and "minute" display portions 13a of the display section 13 to "0:00" and displays "seconds". ”The display in the display part 13b is turned off and the characters 14d indicating the counter mode in the display part 14 are displayed. And start/
When the hold switch 44 is pressed, the time counting operation starts at the same time as the press operation, and the "minutes" and "seconds" of the elapsed time from this start timing are displayed in the "hour" and "minute" display parts 13a. become. When the start/hold switch 44 is pressed and operated again, the time counting operation is stopped at that operating timing, and the "hour" and "minute" display areas 13a display the elapsed time until the stop timing. If the reset switch 45 is then operated, the time counting operation will be reset and "0:00" will be displayed again. Here, the time counting operation will be performed for a maximum of 99 minutes and 59 seconds. Of course, it can be used together with the sleep timer function section 34. In FIG. 1, SWb 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 an auto-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 set, the light-emitting element _L1 goes out, and the timer operates. Indicates that this is not done. Reference numeral 46 denotes a key switch, which is a switch for setting the timer control function section 27 to start a timer operation several seconds before the set time, for example, to correspond to a recorder that takes several seconds to start up. Ryb in Figure 3 is a relay.

Although FIG. 5 shows blocks in terms of operational functions, in the embodiment of the present invention, a one-chip microcomputer is used to process each operation according to a program stored in the built-in ROM in advance. There is.

The present invention includes a channel display section that displays channel numbers of a plurality of programs, an outlet display section that has characters for outlet display arranged adjacent to each of the channel numbers, and a "day of the week" that counts the current day of the week. a counter section, a "day of the week" memory that stores the preset day of the week;
A converter that compares the outputs of the day of the week counter unit and the day of the week memory and outputs an output signal when both outputs match, and a display control function unit that blinks and displays the characters of the preset outlet based on the output signal of the converter. Therefore, you can tell which day the timer is operating and which outlet is being controlled by the blinking display of the outlet characters.For example, you can replenish the recorder with recording tape, or prevent recording if you run out of recording tape or forget to insert it. This has an excellent effect of preventing accidental dripping.
