Description

[Detailed description of the invention] The present invention relates to a multi-action electronic digital timer that can display the "day of the week" on the current time display and can set the timer operating time including the "day of the week" setting. It is.

Conventionally, for timers that can display the "day of the week" on the current time display and also allow the setting of the timer operating time including the "day of the week" setting, it is necessary to set the timer operating time and adjust the time. In order to set the “day of the week” to
These switches are provided to correspond to each day of the week, and by operating any of these switches, the desired "day of the week" can be set, and the timer operation time can also be set. ``Daily'', which operates at the same time every day
In devices that can be set, a separate "everyday" setting switch is provided for this "everyday" setting, and this switch is operated. For this reason, in such a conventional example, seven or eight switches are required independently to set the "day of the week," and the number of switches mounted on the panel surface becomes extremely large, which increases the cost of the entire device. There are problems in that it is expensive and the operation of the switches is complicated, and also that the design of the panel surface is complicated because of the large number of switches.

The present invention has been proposed in view of the above points, and allows the setting of the timer operating time and the "day of the week" when setting the time to be performed by simply operating a single switch. It is an object of the present invention to provide a multi-operation electronic digital timer that can reduce the number of switches.

The present invention will be explained in detail below with reference to embodiment figures. FIG. 1 shows a front external view of an embodiment of the present invention, and the illustration shows the normal current time display state. The front of the housing 8 is provided with a display section 2 for displaying the day of the week, hour, minute, etc., and an operation section 9 consisting of a rotary switch and a large number of push-on switches. day switch 3 as one of the
is provided. Inside the housing 8, an electronic circuit block 1 composed of one or more LSIs and other circuit elements are housed, and this electronic circuit block 1 measures the current time including the "day of the week". In addition to having a clock function that displays this information or sets the time, it also has a timer function that controls the power supply circuit of an external load to turn on and off when a pre-programmed predetermined time has arrived. It has a sleep function that turns off the power supply circuit of the external load after a preset period of time has elapsed, and a counter function that calculates the elapsed time from the counter start. When setting the timer operation time of timer off for one channel, it is possible to independently set the timer operation time for many channels (four channels in the illustrated embodiment),
Furthermore, when setting the timer operating time for each channel, it is possible to specify the "day of the week" or "every day", the "hour", and the "minute". Furthermore, one or more of the above
The electronic circuit block 1 configured by LSI has a built-in operation control section 10 for selecting various functions as described above and controlling their operations. The operation of each part inside the electronic circuit block 1 is controlled in response to the operation output of the electronic circuit block 1. Part or all of this operation control part is implemented by a microprocessor or similar device.
It may also be configured with LSI.

Therefore, the electronic circuit block 1 is, for example, a second
It has a functional and operational configuration as shown in the figure, and the clock circuit section 7 normally has a clock generating section 11.
The current time is calculated by receiving and counting the output pulses of the function selection switch 4 of the operation section 9.
In normal times when the is at the current time display position, the display unit 2 is driven by the output of the clock circuit unit 7 via the display control unit 12, and the display unit 2 displays the current time such as "day of the week,""hour," and "minute." Day display 2a, hour display 2b, and minute display 2c are displayed, respectively, and when the function selection switch 4 is in the current time display position and the second switch 13 of the operation section 9 is pressed on, the operation is controlled. Part 1
0 operates to switch the display control section 12, and the display section 2 switches to the hour display 2b and minute display 2c, and the "minutes" and "seconds" of the current time are displayed for a certain period of time (3 seconds). become. When the function selection switch 4 is set to the time setting position as shown in FIGS. 7 to 7, the electronic circuit block 1 enters the time setting mode, and the
The counter, "hour" counter, and "minute" counter count up or count down at high speed (0.25 second intervals) by the output of the clock generator 11 when the day switch 3, hour switch 14, and minute switch 15 of the operation section 9 are operated, respectively. When the time reaches the predetermined time value to be set, each of the above switches 3, 14, 15
When the operation is stopped, the contents of the "day of the week,""hour," and "minute" counters will be adjusted to the time at this time value. That is, for example, if the day switch 3 is pressed and operated, the day display 2a on the display section 2 will be displayed.
As the "day of the week" counter in the clock circuit section 7 performs the above-mentioned counting operation, "MON" and "MON" are sequentially changed from "SUN" as shown in FIGS. 4, 5, 6, and 7. TUE"..."SAT", and when the desired day of the week is displayed, release the press of the day switch 3, and the contents displayed on the day of the week display 2a at that time will be set as the current time. Similarly, when the hour switch 14 is operated, the numbers from "1" to "23" and "0" are displayed in order as the hour display 2b, and when the minute switch 15 is operated, the numbers "1" to "23" and "0" are displayed sequentially.
The numbers from "59" to "00" are sequentially displayed as the minute display 2c, and the time is set in the same way as when setting the "day of the week". Furthermore, day switch 3, hour switch 14,
When the minute switch 15 is turned on for a short period of time, each time the minute switch 15 is turned on.
Since the minute displays 2a, 2b, and 2c are sequentially advanced one step at a time, the one-shot operation may be stopped at the required step to adjust the time. After this, when the second switch 13 is operated, the "second" counter is reset to "00", and the clock starts operating from the moment when the second switch 13 is released, and the time is set in this way. After the clock starts operating in this state, set function selection switch 4 to
As shown in the figure, it returns to the current time display position, so that the day, hour, and minute switches 3
Even if you operate , the display state of the current time will not change.

Next, the timer setting section 17 is a circuit section that sets and stores the time at which the timer operation should be performed.When the function selection switch 4 is set to the timer set position, the timer setting section 17 enters the timer set mode, and the timer on and timer off operation times can be set. It is what it is.
When setting the timer on/off operation time, please refer to 1.
The timer operation time is set for each channel, with one timer on and one timer off performed by specifying a time within 24 hours a day as one channel.
After specifying the desired first to fourth channels for which the timer operation time is to be set using 0, 21, 22, and 23, turn the on switch to determine whether the timer should be turned on or off at the timer operation time that is set next. 18 or off switch 19, and the day, hour, and minute switches 3, 14, and 15 are operated in the same manner as the time setting operation to set the timer operating time. Thus, when setting the timer operation time, the "day", "hour" and "minute" counters in the timer setting section 17 are set to the day, hour, and minute switches 3,
14 and 15 to set the desired timer operation time value, and select ON switch 18 or OFF switch 1 to determine whether the timer is ON or OFF at this time.
9, and input these values and specified contents to the first to fourth channel switches 20, 21, 2.
2 and 23, and the memory section of each channel stores one on-operation setting time and one off-operation setting time, respectively. Therefore, the timer control section 24 operates when the current time output from the clock circuit section 7 reaches the timer on or timer off setting time of any channel stored in the timer setting section 17, and performs the timer operation specified at this timer setting time. The external load control unit 25 is operated by determining whether the switch 26 is on or off, and the external load control unit 25 turns the switch 26 on or off, and connects the power plug to the plug receiver 27. Controlled external loads, such as audio equipment, are turned on and off. When setting the "day of the week" when setting the timer operation time, in addition to setting the timer operation time specifying each day of the week, it is necessary to turn the timer on and off at the same time on each day of the week, that is, at the same time every day. In some cases. Then, when you operate the day switch 3, the day display 2a for each day of the week from "SUN" to "SAT" will appear as in the case of setting the time described above.
After doing this in sequence, as shown in Figure 8, the day of the week display 2a that displays all days of the week from SUN to SAT is performed, and then the sequential operation is performed to return to the display of "SUN", and the above-mentioned In the same way as setting the time, press the day switch 3 to set the day display 2.
If a is set to start the sequential operation described above and to operate a controlled external load such as an audio device at the same time every day, the day display 2a will change from SUN.
With all days of the week up to SAT displayed, release day switch 3, and first set all days of the week in timer setting section 1.
7 and then set the time in the timer setting section 17 in the same way as in the case of time adjustment described above, so that the controlled external load can be set to operate at the same time every day for the desired channel. It is set as.

The counter/sleep function unit 28 has a built-in counter for time measurement, receives the clock signal from the clock generator 11, performs a count-up or count-down operation, and performs a counter function (time measurement function) or a sleep function. , here, whether to operate the counter function or the sleep function is determined by the operation control unit 1 based on the operation of the operation unit 9.
The selection is controlled by 0. Here, the counter function is a function similar to a stopwatch that integrates and displays the time from the start signal input time, and the sleep function automatically shuts off the external load power supply circuit after the set sleep time has elapsed. It is a working function. First, let's talk about the counter function. When function selection switch 4 is set to the counter function selection position, electronic circuit block 1
enters the counter function mode, and the display control section 12 outputs the counter and sleep function section 28 to the display section 2.
At this time, since the content of the counter inside the functional section 28 is "0", [00:00] is displayed on the display section 2. After this, when the start switch 29 is pressed, the time counter operation will start from the moment the start switch 29 is released, and the minutes and seconds that have elapsed from this start timing will be displayed on the display section 2. . Next, when the hold switch 30 is pressed and operated, the above-mentioned time counting operation is stopped at that operation timing, and the display section 2 displays the elapsed time up to this stop timing, and after this, when the reset switch 6 is operated, The time counting operation by the built-in counter is reset, and [00:00] is displayed again. Here, the time counter operation will be performed for a maximum of 99 minutes and 56 seconds due to the built-in counter. On the other hand, if the function selection switch 4 is set to the current time display position and the sleep switch 5 is operated to set the sleep function mode, the counter and sleep function section 2 will be displayed as soon as the sleep switch 5 is operated.
8's built-in counter is first set to "99" minutes,
This will be displayed on the display section 2, but at this time, the display section 2 will only display the function section 28 while the sleep switch 5 is pressed and for a few seconds after the push operation is released.
is displayed on the display section 2 via the display control section 12, and at other times, the current time based on the output of the clock circuit section 7 is displayed on the display section 2 via the display control section 12. In this way, after the display section 2 shows "99" minutes due to the operation of the sleep switch 5, if the operation of the sleep switch 5 is continued, the built-in counter in the function section 28 will start counting at high speed (for example, every 0.25 seconds). A subtraction count operation is started, and the display on the display unit 2 is gradually decreased from "99" to "98" to "97", etc., and this display time reaches the desired sleep setting time. When the sleep switch 5 is released, the sleep time is set.
Then, the sleep time measurement operation is started. After this, the built-in counter of the functional unit 28 sequentially subtracts 1 from the set sleep time at fixed time intervals (1 minute intervals), and when the content of the built-in counter reaches "00", The output of this functional section 28 is transmitted to the external load control section 25, and the power supply circuit of the external load is cut off. After setting the sleep time by operating the sleep switch 5, the display section 5
In this example, the current time is displayed by the output of the clock circuit section 7, but if the sleep switch 5 is pressed and operated as appropriate, the output of the function section 28 is transmitted to the display section 2 for a few seconds, and the remaining sleep time is displayed on the display section 2. The time will be displayed.

Note that the circuit block diagram shown in FIG. 2 in the present invention shows the operational functions of the electronic circuit block 1, and there is no need to configure the circuit as shown in FIG. 2 as a specific circuit configuration. Therefore, the circuit portions in the circuit shown in FIG. 2 may be shared with each other or may be divided to construct a specific circuit. Furthermore, regarding the operational function of controlling the operation of each circuit in the electronic circuit block 1, which has been explained as the operation of the operation control section 10, a fixed circuit that performs hardware processing on the output of the operation section 9 to control the operation of each circuit section is used. Although it may be realized by a configuration, the above functional operation may also be realized by using a microprocessor or the like and controlling the operation of each circuit section through software processing by programming. Furthermore, when the operation corresponding to the operation of the operation control section 10 is performed by a microprocessor, some of the operations in other circuit parts [for example, timer setting] may be included in the electronic circuit block 1 of the circuit block diagram of FIG. 17 and the timer control section 24] can also be performed by this microprocessor.

Set the minute and second input terminals 31, 32, 33, and 34 to accept input, and in this state, first operate the switches 3, 14, and 15 as detailed above to set the current day of the week, hour, and minute. After adjusting the time, the electronic circuit block 1 starts clock operation by operating the second switch 13 in accordance with a time signal or the like. After the timekeeping operation has been started in this manner, when the function selection switch 4 is set to the current time display position and an input is given to the current time display input terminal 36, the display section 2 displays the current time based on the output of the electronic circuit block 1. In addition, the electronic circuit block 1 cuts off the input circuits of the input terminals 31, 32, and 33, and accidentally switches the day, hour, and minute switches 3, 14,
Even if I operate 15, the time display does not change. Further, as described above, when the seconds switch 13 is operated in this current time display mode, the minutes and seconds are displayed instead of the hours and minutes 2b and 2c on the display section 2. Next, the function selection switch 4 is placed in the timer operation time setting position, Vcc input is applied to the timer operation time setting input terminal 37, and the electronic circuit block 1 is placed in the timer operation time setting mode. , 33 are in a state of accepting input signals, and the day of the week, hour, and minute timer operation times are set by operating the switches 3, 14, and 15 for the day, hour, and minute. At this time, when setting the day of the week, the day display 2a is sequentially advanced from "SUN" to "SAT", and then "SUN" to "SAT" as shown in FIG.
After the entire day of the week is displayed, the day of the week display 2a is sequentially advanced in a cycle of returning to the "SUN" display.

As mentioned above, the present invention is a day of the week display that performs a sequential display operation in which each day of the week is displayed in sequence when setting the "day of the week" of the timer operation time, and all days of the week are displayed in sequence and then all days of the week are displayed simultaneously. and,

Since it is equipped with a timer setting section to set the "day of the week" on which the timer is to be turned on or off, all days of the week can be set in the timer setting section by releasing the press of the day switch while all days of the week are displayed simultaneously on the day of the week display. Later, if you set the time in the timer setting section, you can watch or listen to the same program every day at the same time, and there is no need to set the same time every day of the week like in the past. It becomes easier, saves time, and is more user-friendly.
Moreover, when setting the "day of the week" for the timer operation time,
By pressing the day switch, you can start the sequential display of the day of the week display, and when you release the press of the day switch and the sequential display of the day display stops, you can turn on the timer or turn on the appropriate "day of the week" displayed on the day of the week display. Since the "day of the week" to turn off the timer can be set in the timer setting section, there is no need for seven (or eight) switches to set "day of the week" (and "every day") as in the past. The number of mechanical parts is reduced, making it possible to reduce the price of the equipment, and the number of switches mounted on the panel surface is reduced, resulting in the effect that the panel can have a streamlined design.
