Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to an electronic watch with an alarm function.

[Prior art]

Traditionally, in addition to the memory that stores the time, it also has a memory that stores the date.If the date is not set, it can be used as a daily alarm that generates an alarm at the same alarm time every day.
There are electronic clocks equipped with an alarm function that generates an alarm only at the alarm time on a specific day when the day is set.

[Problems with conventional technology]

In addition to the two alarm functions of the electronic clock mentioned above, you can also set the hourly alarm to generate an alarm every day in that month if you set only the month, and the weekly alarm to generate an alarm only on the day of the week if you set only the day of the week. However, in order to know what kind of alarm function is currently set, it is necessary to actually check the setting status of the month, day, and day of the week, which can be difficult to understand. .

Furthermore, in the case of an alarm for which a date can be set, it may not be clear what rules are used to generate an alarm if the month and day of this date are not set.

[Object of the invention] This invention has been made in view of the above-mentioned circumstances, and its purpose is to solve the problem when message data related to the set date data is set. Based on the message data, it is possible to determine the meaning of the alarm sound when the alarm sound occurs, and on the other hand, it is possible to determine the message associated with the date data based on the set date data. If the data is not set,
When an alarm sound is generated, it is possible to know what type of alarm sound the alarm sound is, and from this, it is possible to set message data specially to determine the meaning of the alarm sound. An object of the present invention is to provide an electronic clock with an alarm function that allows you to know at least one thing.

[Summary of the invention] In order to achieve the above-mentioned object, the present invention has the following features:
When an alarm sound is generated from the alarm sound generating means, if message data is set in the message data storage section, the message data is displayed, and if no message data is set in the message data storage section, the message data is displayed. Based on the date data set in the alarm date data storage section, the display means displays data indicating the type of alarm sound in which date unit the currently occurring alarm sound consists of as message data. The main point is what you did.

[Example] An example will be described below with reference to the drawings. FIG. 1 shows the external appearance of an electronic wristwatch. A display section 2 is provided at the center of the top surface of the case 1, and a push switch S _A (plus direction search) is provided at the bottom of the top surface for searching and reading alarm time and message data preset in the memory. , S _B (minus direction search) are provided. In addition, on the right side of case 1, there is a digit selection switch S _L for writing the data into the memory in the preset mode, and also when operating when setting data to this memory, it is possible to change the alpha alphabet or number for the set digit in alphabetical order or A switch _S1 is provided for cyclically reading out and displaying the numbers in numerical order. Further, on the left side of the case 1, there are provided a switch _S2 for switching to a preset mode, and a switch _S3 for switching between a clock mode and an alarm mode. Inside the case 1, LSI components, batteries, etc. are arranged.

FIG. 2 shows the configuration of the display section 2. As shown in FIG. This display section 2 is composed of a liquid crystal display device, and 3 in the figure is a message display section consisting of a total of 6 digits, each digit being a 5 x 5 dot display, and 4 is a time/date consisting of a date-shaped segment. The display section includes a colon display section 5 and an alarm ON mark display section 6.

FIG. 3 shows the entire circuit. The reference frequency signal outputted by the oscillator 7 is divided by the frequency dividing circuit 8,
The signal is applied to the timing signal generation circuit 9. The various basic timing signals created there are
It is applied to a ROM (read-on memory) 10, a RAM (random access memory) 11, an instruction decoder 12, and an address control unit 13, and drives each of them.

The ROM 10 stores microprograms that control all operations of this electronic wristwatch, and each microprogram is read out from the area addressed by the address control section 13 and executed. The operation code of the microprogram to be read is input from the terminal OP to the instruction decoder 12, and the data is input from the terminal DO to the data bus and stored in the RAM.
11 address input terminal Addr, the address control section 13, and the input terminal DI2 of the calculation section 14, respectively,
Furthermore, the next address data is input to the address control section 13.

The instruction decoder 12 decodes the operation code and provides a read/write control signal to the RAM 11, and also provides a calculation command to the calculation section 14. In addition, RAM 1 is connected to terminals DI ₁ and DI ₂ of the calculation unit 14.
The data read from the terminal DO of 1 is input and the calculation is executed according to the calculation command at that time.
The calculation result data is stored at the terminal DI of RAM11.
sent to and written to. Further, the calculation section 14 outputs a signal of 32 Hz every 1/32 seconds and provides it to the address control section 13. At this time, the clock clock from the frequency dividing circuit 8 is also input to the address control unit 13, and the address control unit 13 responds to this by addressing the address from which the program of the clock processing flow to be executed once every 1/32 second is read. The data is given to the ROM 10, and therefore the arithmetic unit 14
In response to this, an operation is executed to obtain new time measurement data, and the resulting data is stored in the RAM 11.

The data read from the RAM 11 is also input to the decoder 15, converted into display data, and displayed on the display section 2. In addition, the input section 16 is connected to the switch.
S _L , S _A , S _B , S ₁ , S ₂ , S ₃ and the input data from these switches is sent to the data bus.
Written to RAM11.

The instruction decoder 12 also outputs a set signal to the set input terminal S of the SR flip-flop 17 when the alarm time arrives, and outputs a reset signal to the reset input terminal R when the alarm is off.
The set output signal of the flip-flop 17 is applied to the alarm circuit 18 to drive it, and the alarm signal from the alarm circuit 18 is sent to the speaker 19.
It is emitted as an alarm sound.

In this embodiment, up to five types of alarms (alarm 1 to alarm 5) can be preset in the RAM 11 with the alarm time and its message as a pair of data. In this case, the alarm time means the date (month, day, day of the week) and time (hour, minute), and any message can be specified by a combination of alphanumeric characters of up to six characters. Further, the message does not need to be inputted if it is not necessary. If a message is not preset in this way, when the alarm time is read out, a message indicating the type of alarm time is automatically added and displayed on the display section 2 together with the read out alarm time. It's becoming like that. Figure 4 shows the contents of this automatically added message.
An O mark indicates that the corresponding month, day, or day of the week has been set, and an X mark indicates that it has not been set (the time must be set). And the message SCHEDU, MWEEKL,
MDAILY, MONTHL, WEEKLY, and DAILY refer to schedule, monthly weekly, monthly deli, monthly, weekly, and daily, respectively.

Figure 5 shows RAM 1
Examples of data for five types of alarms preset to 1 are shown below. Then, the symbol "-" is added to the date data part.
-" indicates that data is not set. Also, a blank part of the message indicates that the message is not set.

Next, the operation of the above embodiment will be explained with reference to the flowcharts of FIGS. 6 to 9 and the transition diagrams of FIGS. 10 and 11. First, a write process for presetting alarm times and messages as shown in FIG. 5 in the RAM 11 as first to fifth alarms will be described in accordance with the flowchart of FIG. 6.

When the preset mode is set by switching switch _S2 and the writing process starts, the RAM
11, the alarm time and message of the currently addressed alarm are sent to the display section 2 via the decoder 15 and displayed (display processing in step _W1 ). Next, operate the digit selection switch S _L to select and specify the digit of the data to be input.
Input the actual data by operating _S1 . In this case, the digits of the data are hours (1st digit), minutes (2nd digit), seconds (3rd digit, but not set), month (4th digit), day (5th digit), and day of the week. (6th digit), 1st character (7th digit) to 6th character (12th digit) of the message
means. The data of each digit is displayed in correspondence with the indicator at the position shown in FIG. Furthermore, each time the digit selection switch S _L is operated, the digit counter in the P register in the RAM 11 is incremented by 1 (increment processing in step _W3 ). In this case, the count value P of the digit counter is 0, 1, 2,...
..., 11 are the first, second, and third digits, respectively.
..., corresponds to the 12th digit. When the count value P is set to the first digit (hour) of 0,
The numbers 1 to 12 are automatically displayed cyclically on the first digit display in Figure 2 each time switch _S1 is operated, and the data you want to set appears or when you stop operating switch _S1 (Step W ₆ , _W7 , and _W8 ), then operate the digit selection switch S _L once to set P=1 (step _W3 ), and specify the second digit. At this time, the numbers 00 to 59 are cyclically displayed on the second digit display shown in FIG. 2 each time the switch _S1 is operated, and the minute data is selected (steps _W9 ,
_W10 , _W11 ).

Next, operate the digit selection switch S _L twice to set P = 3 and specify the month as the 4th digit. The numbers 1 to 12 will be displayed cyclically on the 4th digit display in Figure 2, and the month data will be displayed. Select (step omitted in Figure 6).

Next, operate the digit selection switch S _L once to set P = 4 and specify the day of the 5th digit. The numbers 1 to 31 will be displayed cyclically on the display of the 5th digit in Fig. Select data (step omitted).

Next, operate the digit selection switch S _L once to specify the day of the week in the 6th digit by setting P = 5, and the abbreviations of the days of the week from SU to SA will appear in the 6th digit display in Figure 2. is displayed, and the day of the week data is selected (steps W ₁₂ , W ₁₃ , W ₁₄ ).

Next, operate the digit selection switch S _L once and set P = 6 to specify the first character of the message in the 7th digit. The alphabets from A to Z will be displayed cyclically on the 7th digit display in Figure 2. and select the first character of the message (steps W ₁₅ , W ₁₆ ,
_W17 ). The second to sixth characters of the message are the same as the first character, and after operating the digit selection switch S _L once to specify P = 7, 8, 9, 10, and 11, select switch S ₁ . Select the desired character by operation. When P=12, this is determined by the process in step _W4 , and the digit counter of the P register is cleared (step _W5 ). Then, the writing process for one alarm ends.

Next, referring to FIGS. 7 and 10, RAM1
1, the operation of reading out the first to fifth alarms (FIG. 5) preset by the above writing process and displaying them on the display section 2 will be explained. The read mode is set by switching switch _S2 ,
When the alarm reading process starts, the step
For example, the data of the first _alarm (the fifth
(See figure, data for the time "6:45") is read out. Then, the presence or absence of the message is determined (step R ₁ ), and since there is no message, the presence or absence of the month data is then determined (step R ₄ ), and since there is no message, the presence or absence of the day data is further determined (step R ₁₂ ). Since there is no data, proceed to step R ₁₄ and the data "DAILY" will be displayed instead of the message. That is, the display shown at A in FIG. 10 shows the display state of this first alarm. In this case, an alarm ON mark is lit on the left side of the "DAILY" display, and a number "1" indicating the first alarm is displayed on the right end of the hour/minute data. Note that this also applies to the second to fifth alarms.

If you operate switch S _A once in the above condition,
The address of RAM11 is incremented, and the second alarm data “May 20th, 10:30,
"NARITA" is read out. Then, in step _R2 via step _R1 , it is determined that there is a message, and the message display process is performed in step _R3 .
As shown in Figure 0B, the preset message "NARITA" is displayed as is. Of course,
The month, day, and hour data are also displayed as is.

Next, when switch S _A is operated once more, the third alarm data "June 23rd, 8:30" is read out. In this case, the presence of month data is determined in step _R4 via steps _R1 and _R2 , and the process proceeds to step _R5 , and then the presence of day data is determined and step R4 is performed.
Receive R ₆ SCHEDU display processing. Therefore, instead of no message, a message "SCHEDU" indicating the type of third alarm is automatically displayed as shown in C of FIG. 10.

When switch S _A is operated one more time, the fourth alarm data "SU, 8:00" is read out. Therefore, the presence of day of the week data is determined in _R12 via steps _R1 , _R2 , _R4 , and _R10 , and the presence of day of the week data is determined in step _R13 .
Receives WEEKLY display processing. Therefore, as shown in D in Figure 10, instead of no message, the fourth
Message “WEEKLY” indicating the type of alarm
is displayed.

When you operate switch S _A one more time, the fifth alarm data “July 23rd, 3:00,
``HANAKO'' is read out. Therefore step
Through each process of R ₁ , R ₂ , and R ₃ , the preset message "HANAKO" is displayed together with other date and time data, as shown in E of FIG. In addition, if you operate switch S _B , RAM
11 is decremented, the order in which the alarm data is read is reversed from the above case.

Next, the general operation will be explained with reference to FIGS. 8, 9, and 11. When the arithmetic unit 14 outputs a signal of 32 Hz and supplies it to the address control unit 13, the address control unit 13 reads a timekeeping processing program from the ROM 10 and causes the arithmetic unit 14 to execute a timekeeping operation (step G ₁ ). In that case, the previous time data and date data are read from a predetermined register in the RAM 11, a predetermined value is added thereto, and new data is set in the register again.

When the time measurement process is completed, it is determined whether the switch _S3 for changing the clock mode or alarm mode has been operated (step _G3 ), and if it has not been operated, the process jumps to step _G6 and the M register in the RAM 11 is changed. It is determined whether the data is "0" or not.
If it is "0", the clock mode is being set, so proceed to step _G7 , and on the other hand, the clock mode is being set.
It is in alarm mode and the step
Proceed to G ₁₅ .

On the other hand, when it is determined in step _G2 that the switch _S3 has been operated, the process advances to step _G3 , and the switch S3 is operated.
Determine whether the data in the register is "1" or not. If it is "1", it means that it is currently in alarm mode, so proceed to step _G4 and set the flag "0" to the M register.
and set the clock mode. On the other hand, “1”
If not, you are currently in clock mode, so step
Proceed to _G5 and set the M register to "1" to set the memory mode. Then, when proceeding to step _G7 via step _G6 , it is determined whether the data in the F _A register is "0" or not, and if it is "0", one of the first to fifth alarms is activated. This indicates that the set time has been reached, so
This is determined by the processing in step _G8 ,
After setting data "1" in the F _A register (step G ₉ ), the flip-flop 17 is set to start emitting the alarm sound (step G ₁₀ ), and the message display process described above (step G ₁₁ ) is started.
I do.

On the other hand, the alarm sound that has started to be emitted in this manner will proceed to step _G12 through the process of step _G7 when the flow shown in FIG. 8 is executed from the next time onwards.
It is determined whether or not the sound has been emitted for a certain period of time, and when the sound has been emitted for a certain period of time, the flip-flop 17 is reset and the alarm sound stops (step _G13 ). Then, the display returns to the normal time display in clock mode (step _G14 ).

In addition, in FIG _{. 11} , _the clock mode display (symbol A) and _the alarm _mode display (symbol B ) indicates that they are mutually cut between.

On the other hand, when proceeding to step _G15 , the F _A register is set to “1” because the alarm mode is being set.
If it is "1", the flip-flop 17 is reset to stop emitting sound, and the process proceeds to step _G17 . Also, if it is not "1", the sound is not being emitted, so immediately proceed to step _G17 and switch S _A
It is determined whether or not switch S _B has been operated. Steps G ₁₇ , G 18 , G 19 , G ₂₀ when switch S _A is operated or steps G 17 , G ₁₈ , G ₁₉ , G 20 when switch S _B is operated.
Each process of G ₂₁ , G ₂₂ , G ₂₃ , G ₂₄ is the first alarm ~
This is a fifth alarm switching setting process. Then, proceed to step _G25 and the data in the L register will be "0".
If it is "0", it means that the first alarm has been selected by operating the switch S _A or S _B , and the process advances to step _G26 to execute preset and read processing for the first alarm. be done. On the other hand, if the register is not “0”, the step
Proceeding to G ₂₇ , it is determined whether it is "1" or not. If it is "1", the second alarm is being selected, and the second alarm processing is executed (step _G28 ).
Similarly, the data in the L register is "2", "3",
When the value is "4", the third alarm, fourth alarm, and fifth alarm are being set, and each process is executed.

FIG. 9 is a flowchart specifically showing the alarm processing (steps G ₂₆ , G ₂₈ , G ₂₉ ) of the first to fifth alarms. First, switch
It is determined whether S ₂ has been operated (step
_A1 ). Switch _S2 is a switch for changing between alarm preset mode and readout mode,
If switch S ₂ is operated, the process advances to step A ₂ to determine whether the data in the _FP register at that time is “0” or not. If it is “0” (during read mode setting), the data in the _FP register is Set “1” (step
A ₃ ), and clears the P register (this register constitutes a digit designation counter at the time of presetting) (step A ₄ ), and proceeds to step A ₆ . On the other hand, if the F _P register is not “0”, the F _P register is “0”.
(Step _A5 ) and proceed to Step _A6 .
Then, in step _A6 , the F _P register is set to “0”.
If the alarm time and message are set, the above-mentioned reading process of the alarm time and message is executed (step _A7 ),
On the other hand, if "1" is set, the process advances to step _A8 and the above-described alarm time and message setting process is executed.

[Effects of the Invention] As explained above, the present invention is capable of displaying the message data if the message data is set in the message data storage section when the alarm sound is generated by the alarm sound generating means. However, if no message data is set in the message data storage section, the currently occurring alarm sound will be set to any date unit based on the date data set in the alarm date data storage section. Since the display means displays data indicating whether the date is the same as the message data, if message data related to the date data is set for the set date data, the message data Based on this, the meaning of the alarm sound can be determined when the alarm sound occurs, and on the other hand, it is possible to determine whether message data related to the date data has been set for the set date data. If not, it is possible to know what type of alarm sound the alarm sound is when it occurs, and to specially set the message data to know what kind of meaning the alarm sound has. You can know without knowing.
