Description

Detailed Description of the Invention This invention relates to an alarm clock that stores multiple alarm times and displays the status of these alarms.

When a plurality of alarm times are stored, it may be difficult to know for what purpose the alarm time was stored even if an alarm sound occurs. In order to prevent this, it has been proposed to vary the alarm sound and to provide a display with a name corresponding to each alarm time. However, all of these systems have the drawback that when no alarm sound is generated, the user cannot know what the next alarm will be for, and cannot prepare for it.

In view of the above points, the present invention aims to provide an easy-to-use alarm clock in which the next alarm time is displayed in advance for multiple alarm times. purpose.

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

FIG. 1 shows a block diagram of the main parts of this embodiment. 1 is a timing signal source including an oscillator and a frequency divider; 2 is a register for storing time such as hours and minutes; the output of the timing signal source 1 is counted up every predetermined time (for example, every minute) to measure time. Although not shown, the clock is displayed by displaying the contents of the register 2. Reference numeral 3 denotes an alarm memory for storing a plurality of alarm times A, B, . 5
A coincidence detection circuit detects coincidence between the current time stored in the register 2 and the alarm time outputted from the alarm memory 3, and its output is input to the alarm sound generation circuit 6 and the address counter 4. Reference numeral 7 indicates indicators named by printing or the like corresponding to the alarm times A, B, .

Now, each time a coincidence signal is output from the coincidence detection circuit 5, the address counter 4 counts up, and the designation of the alarm time to be output from the alarm memory 3 is sequentially changed. For example, if 7:00 is stored as alarm time A and 8:00 is stored as alarm time B, and address counter 4 specifies alarm time A, then the time contents of register 2 are set to 7:00. At the same time, the coincidence detection circuit 5 outputs a coincidence signal, drives the alarm sound generation circuit 6, and at the same time counts up the address counter 4 to set the next alarm time B.
Specify.

In this way, the address counter 4 is incremented every time a coincidence signal is output from the coincidence detection circuit 5, and the output of the address counter 4 drives the display 8. In the above case, when the time content of the register 2 becomes 7:00, the address counter 4 outputs an output to specify the alarm time B of the alarm memory 3. The displayed display bodies 8A and 8B are turned on. This indicator 8A/B lights up at 8:00.
This continues until the next matching signal is output. By lighting the display 8 in this manner, the next alarm time can be known in advance, and what should be done at the alarm time can be known.

FIG. 2 is a block diagram of main parts showing another embodiment, in which only the first display element blinks, and the display elements to the left of it are always lit. 9 is an AND gate that inputs each designated output of the address counter 4 and the blinking drive signal P;
Reference numeral 10 denotes an OR gate which inputs the output of the undo 9 and each subsequent specified output of the address counter 4.

For example, if the time contents of register 2 are now between alarm times B and C, then address counter 4 is stored in alarm memory 3 (see Figure 1).
output to specify alarm time C. Therefore, at this time, the display bodies 8B and 8C provided between the indicators 7B and 7C are driven to blink by the blinking drive signal P input through the AND gate 10B. In addition, this specified output is also applied to the display bodies 8A and 8B provided to the left of the display bodies 8B and 8C.
It will be input via 0A, and the display 8
Drive A and B to light up. Such a display is very convenient because it allows the user to know the passage of time and also allows him to know in advance what the alarm time will be like based on past conditions.

In the above embodiments, the indicators are formed by naming them by printing or the like, but of course, they may be formed with an optical display and driven electrically without any problem. Further, by using such an optical display, it is possible to turn on or blink at the same time as the alarm sound is generated, which is useful because it is possible to directly know which alarm time has been set.

As described above, according to the present invention, in an apparatus that stores a plurality of alarm times, it is possible to read at a glance what the next alarm is for by displaying it.
To provide a clock with an alarm that allows a user to immediately wake up and has high practical value.
