Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic timepiece that can store and display a large amount of data in addition to time data.

Recently, electronic watches have become more and more multi-functional, and it is being considered to input data such as alphabets, katakana, and numbers to store information such as addresses, telephone numbers, timetables, and messages. Information such as addresses, telephone numbers, timetables, etc. is stored in different memory areas selected by external operation switches, and read out and displayed as necessary. If the number of types increases, a problem arises in which information different from the information designated by the external operation switch is input or displayed in the memory area selected by the external operation switch. For example, problems such as accidentally entering a telephone number when the memory area where addresses are stored are selected by the external operation switch, or misreading the time on the timetable as the current time. It is.

In addition, when inputting data, input characters are alphanumeric characters, katakana characters, numbers, etc., so if an input switch is provided for each character, the number of switches becomes extremely large, which also has the disadvantage of making the clock itself larger. Ta.

This invention was made in view of the above points,
The purpose of this is to easily identify the type of information displayed by displaying the type of information using characters, symbols, or figures, to prevent incorrect input or reading errors, and to use an extremely small number of switches. To provide an electronic clock capable of inputting a large number of characters such as alphanumeric characters.

From the second memory 36, via gate _G7 ,
Data from the third memory 37 is connected to the display buffer 24 via the gate _G8 .
The signals on the output line e of the decoder 31 are input to these gates _G6 to _G8 as gate control signals, respectively.

Next, the operation of the present invention configured as described above will be explained. First, in normal times, the content of the mode counter 30 is "0" (time display mode).
Therefore, the gate G ₁ is opened and the time information counted in the counter 23 is "December 24th (Sunday) 10:00 am."
50 minutes 10 seconds" is sent to the dot matrix display unit 26 via the display buffer 24 and display drive circuit 25 and displayed as shown in FIG. Next, when the mode selection switch _S1 is operated to set the mode counter 30 to "1", the alarm display mode is entered.
That is, the gate _G2 is opened by the output line c, and the alarm time information "12:30 p.m." preset in the alarm circuit section 27 is displayed on the gate G2.

A coincidence signal is output from 7 to the alarm device 28, and an alarm is sounded. However, mode selection switch S ₁
Set the mode counter 30 to "2" (data write mode) by operating . Then, the output lines c and d open the AND circuits 33, 39, 45 and the gates _G3 to _G5 , respectively. next,
The memory selection switch determines which of the first to third memories 35, 36, and 37 the data will be written to.
This is done by operating _S2 to set the count value of the memory selection counter 34 to a predetermined value. That is, when the count value of the memory selection counter 16 is "0", the first memory 35, when this count value is "1", the second memory 36, and when this count value is "2", the third memory 37 is selected. Here, as described in the above explanation of the configuration, in this embodiment, the first memory 35 has a timetable, the second memory 36 has a telephone number (including name), and the third memory 37 has an address. (address) is written. In addition, the memory selection counter 24
The count value of is displayed through gate G ₃ and buffer 24
sent to. When the count value of the memory selection counter 34 is "0", the train mark (FIG. 7A) is displayed, and when the count value is "1", the telephone mark 26a (FIG. 4) is displayed. In the case of "2", the address mark (FIG. 7B) is displayed at the upper right of the dot matrix display section 26, and the
5 to 37 is selected.
Now, for example, if the memory selection counter 34 is set to "1" and the second memory 36 is selected, the phone number and name "243-" are stored in the second memory 36.
1513GEOAGE" is written.
First, when the data selection counter 40 is set to "0", the counted value "0" of the data selection counter 40 is sent to the data code generation section 41. As a result, data codes for the numerical values "0" to "9" are sent from the data code generating section 41 to the buffer 42. Next, operate switches T ₀ to T ₉ to input phone numbers "243-1513" in sequence.
Then, the switch T ₀ to T ₉ operation signal is sent to the data code selection section 47, and the numerical data code corresponding to the switch T ₀ to T ₉ is sent to the display buffer 24 and displayed as shown in FIG. be done. When entering the phone number, please enter the hyphen "-"
For example, enter the hyphen "-".
It is sufficient that the input is made when any two of T ₀ to T ₉ are operated at the same time. Next, when inputting the name "GEORGE", the data selection switch _S3 is operated to set the data selection counter 40 to "2". Then, the count value "2" of the data selection counter 40 is sent to the data code generation section 41. As a result, data codes corresponding to the alphabets "A" to "J" are sent from the data code generating section 41 to the buffer 42 and the display buffer 24, respectively. Ten alphabets "A" to "J" are displayed in the lower row of the dot matrix display section 26 corresponding to the switches _T0 to _T9 . This will cause the switch T ₀ to
T ₉ The data that will be entered when operated is displayed above each key. Then, when the "6" key and the "4" key are operated in sequence, the operation signals are sent to the data code selection section 47, and the alphabet "G",
The data code for "E" is selected. The data codes for these alphabets "G" and "E" are sent to the display buffer 24 and displayed on the dot matrix display section 26 (FIG. 5), and are also written into the second memory 36. In FIG. 5, the position where the "↓" display section 26b is displayed indicates that the next data to be input will be displayed. This “↓” display 26b is controlled by the display buffer 24. Next, the alphanumeric character "O" is input, but since only alphanumeric characters "A" to "J" can be input in the state shown in FIG. 5, the readout switch _S4 is operated. The operation signal for this switch _S4 is AND circuit 45
The next 10 data are sent to the data code generator 41 via
Data codes of letters "K" to "T" are sent to the buffer 42. Then, "K" is placed in the positions corresponding to switches T ₀ to _{T 9} , respectively.
~ "T" is displayed (Figure 6). Here, "4"
Operate the keys to input the alphanumeric character "O". The data code for the alpha bet "O" is sent to the display buffer 24 and displayed on the dot matrix display section 26, and is also written into the second memory 36. Thereafter, alphabets "R", "G", and "E" are input in the same manner. In this way, the phone number "243-1513" is stored in the second memory 36.
The name "GEORGE" is memorized. Alternatively, when entering the name in katakana characters, the data selection switch _S3 is operated to set the data selection counter 40 to "1". The count value "1" of the data selection counter 40 is then sent to the data code generation section 41. As a result, data codes for 10 katakana characters "a" to "ko" are generated from the data code generator 41 in buffer 4.
Sent to 2. The data code for these 10 katakana characters "A" through "K" is sent to the display buffer 24 and displayed on the dot matrix display section 26 as shown in FIG. Also,
The following 10 characters will be displayed by operating Switch S ₄ , and 50 characters will be displayed.
Any sound can be input. Next, a case will be described in which the timetable data, telephone number data, and address data stored in the first to third memories 35 to 37 are displayed on the dot matrix display section 26. In this case, operate the mode selection switch S ₁ to set the mode counter 30 to "3".
Set. This opens the AND circuit 44 and the gates _G6 to _G3 , respectively. next,
The memory selection counter _S2 is operated to set the count value corresponding to the first to third memories 35 to 37 in the memory selection counter 34. Now, for example, if the telephone number stored in the second memory 36 is to be displayed, the memory selection counter 34 is set to "2". Next, when the readout switch _S4 is operated, a one-shot pulse is generated via the AND circuit 44.
It is output to the memory 36. As a result, the address of the second memory 36 is updated every time the switch _S4 is operated, and the contents stored in the second memory 36, ``name'' and ``telephone number,'' are displayed on the dot matrix display section 26. Further, FIG. 9 shows a state in which the name "GEORGE" and the telephone number "243-1513" are displayed.

In the above embodiment, the first to third memories 35 to 37 are selected by operating the switch _S2 , but the storage contents of each memory are not limited to this, as shown in FIG. Of course, marks may be displayed in correspondence with the numeric keys □1, □4, and □7, and the memory may be selected by operating any of the numeric keys □1, □4, and □7. .

As described in detail above, according to the present invention, it is possible to easily identify in which memory area the input character information is stored, which not only prevents malfunctions but also enables the input of character information to be stored in a large number of types, such as numerical values and alphanumeric characters, with a small number of switches.
