Description

[Detailed Description of the Invention] The present invention relates to a timer display device that allows the setting state and operating state of a timer to be easily seen.

Conventionally, this type of timer display device, for example, as shown in FIG. 1, includes a digital display 1 that displays time data, an analog clock 2, and timer LEDs 3a and 3 that display the operating and non-operating states of the timer.
a, digital display 1, timer LED 3a, 3
A device is known that is equipped with a control device 4 that drives the device b, manages time, and controls the controlled device.

According to the above timer display device, timer LED3
Whether or not timer operation is possible can be determined by turning on or off lights a and 3b. Further, when a key (not shown) is operated to enter the timer check mode, time data such as the on time and off time of the timer can be displayed on the digital display 1.

However, it is difficult to understand the relationship between the timer setting time and the current time, and when multiple timer times are set, it is difficult to understand the relationship between the timer times. There were drawbacks such as the need for dedicated timer LEDs 3a and 3b.

The present invention has been made in view of the above circumstances, and its purpose is to provide a timer display device that makes it easy to understand the relationship between the timer setting time and the current time.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is a plan view showing an example of the timer display device of the present invention. In the figure, numeral 5 is a digital display that displays time data, 6 is an analog clock, 7 is a dot display provided around the analog clock 6, and 8
1 is a control device consisting of a microcomputer, which drives the digital display 5 and dot display 7, manages time, and controls controlled devices (not shown).

As shown in FIG. 3a, the dot display 7 is configured in a ring shape with a group of 12 dots 7a.
It is designed to display 12 hours per lap. These dot groups 7a are composed of six LEDs as shown in FIG.
It consists of The anodes of each LED are connected to the collectors of transistors T _D1 to T _D6 , respectively, and the dot group 7a indicating 1 o'clock is
The cathode of the LED is connected to the collector of the transistor T _G1 , and similarly the cathode of the LED of the dot group 7a that displays 2 o'clock, 3 o'clock...12 o'clock is connected to the collector of the transistor T G1.
T _G2 , T _G3 ... are connected to the collector of T _G12 , respectively. Signals are sent to the bases of the transistors T _D1 to T _D6 and T _G1 to _{T G12} from terminals D ₁ to _{D 6} and G ₁ to _{G 12} of the control device 8, respectively, and by sending these signals, The dot display 7 is driven and time is managed.

The control device 8 includes two timers each having an on-data storage section that stores on-time data and an off-data storage section that stores off-time data, as well as a clock section that measures the current time and the above-mentioned timer section. It is equipped with a display control section that drives the digital display 5 and the dot display 7 using data in the data storage section, and is also connected to a numeric keypad input device 9, and a key switch 9a of the numeric keypad input device 9.
Operating key switch 9b switches to one timer mode, operating key switch 9c switches to timer check mode, and operating key switch 9d switches to timer check mode.
When the key switch 9c is operated, the timer on-time setting mode is entered, and when the key switch 9c is operated, the timer off-time setting mode is entered. Normally, the control device 8 sends transistors T _D1 to T so that the LEDs of the dot group 7a corresponding to the current time blink in sequence.
A signal is sent to the bases of D6, T _G1 to _{T G12} . Also, when the current time is within the timer setting time,
That is, during the timer operation, the dot group 7a corresponds to the time from the current time to the timer off time.
A signal is sent from the control device 8 to the bases of the transistors T _D1 to T _D6 and T _G1 to _{T G12} so that the LED lights up.

In FIG. 2, 10 is a drive line for the dot display 7, and 11 is a control line for a controlled device (not shown).

Next, a more detailed configuration of the timer display device will be explained along with its operation.

As mentioned above, the two timers in the control device 8 correspond to one key switch 9a, and the other one corresponds to the key switch 9b. Therefore, when the key switch 9a is operated with the on time 3 o'clock - off time 4 o'clock and on time 6 o'clock - 8 o'clock set in advance for the two timers using the numeric keypad input device 9, one timer is turned on. For example, the following display is performed using the data of the on time 3 o'clock and the off time 4 o'clock held in the data storage section and the off data storage section, respectively.

First, the display control section in the control device 8 reads the on-time data from the on-time data storage section to another data storage section, and lights up the dot corresponding to the time data stored in this data storage section. Thereafter, unit time data (temporal resolution of dots: 10 minutes, for example) is sequentially added to the data in the data storage section, and the dots corresponding to the data obtained by this addition are lit. This operation is repeated until the data matches the data stored in the off-time data storage section. If both data match, the above operation is repeated again. Since this series of operations is performed at high speed, the dots corresponding to 3 o'clock and 4 o'clock are visually recognized as always being lit.

A similar operation is performed when the key switch 9b is operated, and in this case, the data stored in the other on-time data storage section and off-time data storage section are used to The corresponding dot will be lit.

For this reason, in the former case, the display control section of the control device 8 outputs by sequentially adding unit time data to the on-time data read from the on-time data storage section until they match the off-time data. Transistor with terminal _G4 set to H level
With TG ₄ turned on, output terminals D ₁ to D ₆ are sequentially set to L level, and PNP transistors T _D1 to T _D6 whose bases are connected to these output terminals are sequentially turned on and connected to these transistors. has been
Each dot in the dot group 7a consisting of LEDs is turned on in sequence. In the latter case, the control device 8
First, output terminal G ₇ is set to H level, transistor TG ₇ is turned on, and output terminals D ₁ to D ₆ are sequentially set to L level, and the PNP transistor T _D1 whose base is connected to these output terminals is ~T Turn on _D6 sequentially, then turn on output terminal _G8 to turn on NPN
The same operation as described above is performed with the transistor T _G8 (not shown) turned on, and the dot group 7a consisting of LEDs connected to these transistors is
Turn on each dot in sequence.

Incidentally, when both the key switches 9a and 9b are operated, the dot groups 7a corresponding to the times set in the two timers are lit at the same time. Of course, each dot group 7a is selectively illuminated by the output terminals _D1 to _D6 of the control device 8.
The timer setting time can be displayed in 10-minute increments by changing the number of output terminals D ₁ to _{D 6} to set the output level to L level.

As described above, the set time of the timer is displayed by lighting the dot group 7a by operating the key switches 9a and 9b, and at this time, the current time 12:34 is displayed on the digital display 5 and the analog clock 6. With this, by comparing the current time on the digital display 5 or analog clock 6 and the timer setting time display by the dot group 7a, it is possible to know that the timer is currently in a non-operating state. The mutual relationship between the set times of the two timers can also be known from the display of the dot group 7a.

Also, when you operate key switches 9a and 9c,
One of the timers enters the check mode, and as shown in FIG.
The LED lights up, and instead of displaying the current time based on the clock data of the clock section, the digital display 5 displays the timer's on-time data stored in the timer on-time data storage section using well-known means. The on time (3 o'clock) is displayed, and the current time (12:34) is displayed on the analog clock 6.

For this purpose, the display control section of the control device 8 reads out the on-time data stored in the on-time data storage section in response to the operation of the key switch 9a, and outputs the output terminal corresponding to the data.
_G4 is set to H level, and output terminals _D4 to _D6 are sequentially set to L level, and the dots of the corresponding dot group 7a are turned on in sequence at high speed. In addition, the control device 8 reads on-time data of a time set in one timer in response to the operation of the key switch 9c, and displays the read data on a digital display via a signal line (not shown) in place of the current time data. 5
The timer on time is displayed on the digital display 5.

Note that the above-mentioned signal line used to output data indicating the current time from the clock, and therefore, the control device 8 outputs data indicating the current time to the signal line after a certain period of time instead of the on-time data of the timer. By outputting , the timer on time that was displayed up to that point will be automatically erased.

By displaying the timer on time on the digital display 6 in this way,
The accurate timer setting time in units of one minute, which is difficult to determine with the dot group 7a, can be easily confirmed in relation to the current time measured by the analog clock 6.

Also, when you operate key switches 9b and 9e,
The other timer enters the off time setting mode, and the fifth
As shown in the figure, the dot group 7a corresponds to the on time.
A series of dot groups 7a from 1 to 7a corresponding to a settable time period flash as if expanding and contracting.

For this purpose, since the key switch 9b is operated, the display control section of the control device 8 sets the output terminal G ₆ to the H level and the output terminal D ₁ to the L level in the same way as described above, and sets the set ON time. The dot corresponding to 6 o'clock is lit. Furthermore, since the key switch 9e is operated, the control device 8 reads data indicating the set time of one timer, for example, 3 o'clock to 4 o'clock, and data indicating the timer on time set for the other timer, for example, 6 o'clock, Based on these read data, a time period from 6 o'clock to 2 o'clock, for example, which can be set as an off time in the other timer is determined, and this data is stored in a predetermined data storage section. Then, output terminals D ₁ to _{D 6} are connected to L at high frequency.
While the levels are being output sequentially, the output terminals G ₇ to G ₁₂ and G ₁ to G ₂ to G ₇ , G ₈
...Increase the number of output terminals that reach H level by sequentially outputting H level in the order of G ₁₂ , G ₁ , G ₂ at a low frequency of 5 Hz, for example, until all output terminals G ₇ to _{G 2} become H level. Then, the increased data is sequentially 1
The number of output terminals decreases in units of time and, contrary to the above, outputs L level in order from output terminal G ₂ and becomes H level, reducing the number of output terminals, and blinks the dot group 7a corresponding to output terminals G ₇ to G ₂ . Then, the illuminated dot group 7a is expanded and contracted. By doing this, it is possible to notify that the off time can be set between 6 o'clock corresponding to G ₇ and 2 o'clock corresponding to G ₂ , and the off time can be set by blinking the dot group 7a. It is possible to display a prompt to input settings.

In the above embodiment, the dot display 7 is rotated 12 times per rotation.
Although the case is shown as time, it is not limited to this.
One round may be one hour, or one round may be one week. Further, although the case where one dot display 7 is provided around the analog clock 6 is shown, a plurality of dot display devices 7 may be provided concentrically.

As explained above, according to the present invention, since the dot display that displays the timer setting time is provided around the analog clock, the relationship between the current time and the timer setting time can be seen at a glance, and multiple timer Even if you set the time, you can see the relationship between the timer times at a glance. Furthermore, since it can be seen from the dot display whether the timer time is set or whether the timer is operating, a dedicated timer LED is not required.
