Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an input device for a dot matrix display device.

Recently, electronic watches have become more and more multi-functional, and it is being considered to input data such as alphanumeric characters, katakana, numbers, etc., and to store information such as addresses, telephone numbers, messages, etc. in electronic watches. However, it is difficult to provide a large number of input switches for alphabets, katakana, numbers, etc. in a small device such as an electronic watch due to space constraints.

Therefore, for example, as described in Japanese Patent Application Laid-Open No. 49-56531, numbers are automatically switched and displayed character by character on the display section, and when the desired number is displayed, a switch is operated. It is considered to set numeric characters.

However, this type of input method does not require much effort if there are about 10 types of characters, such as numbers, but it does not require much effort when inputting characters such as alpha, katakana, hiragana, etc.
When inputting characters such as kanji, it takes a long time for the desired character to be displayed, making it unsuitable for practical use.

In addition, since the numbers are automatically switched and displayed, if you do not deftly perform the setting operation when the desired number is displayed, the next number will be displayed. There were also some drawbacks.

This invention was made in view of the above points,
Its purpose is to not only allow users to enter numerical and non-numeric character information quickly and without inputting errors with a small number of switches, but also to display a dot matrix display that allows easy confirmation of the entered content. The purpose is to provide an input device for the device.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an electronic wristwatch that displays a dot matrix. In the same figure, 11
is the case itself, and 26 is the dot matrix display section, which displays "December 24th (Sunday) 10:50:10". Further, switch _S1 is a display mode selection switch, which selects time display mode, alarm display mode, data write mode, and data read mode. Further, switch _S2 is a memory selection switch, and selects one of the memories in which timetable data, telephone number data, and address data are respectively stored. Further, switch _S3 is a character type selection switch and is operated in the data writing mode. The switch _S4 is a readout switch, which is operated to read out character codes and to read out and display the timetable data, telephone number data, and address data, as will be described later. In addition, switches T ₀ to _{T 9} are numeric keys corresponding to numbers 0 to 9,
This is a data input operation switch that can also be used to write data other than numerical values.

FIG. 2 is an overall block diagram of the electronic wristwatch that displays the dot matrix shown in FIG. 1. In the figure, 21 is an oscillation circuit that outputs a reference frequency signal. The reference frequency signal outputted from this oscillation circuit 21 is frequency-divided into, for example, a one-second signal via a frequency dividing circuit 22 and inputted to a counter 23 . This counting unit 23 counts the input one second signal and displays "hour", "minute", "second", "day", "month", and "day of the week".
etc., time information is obtained. The time information counted by the counter 23 is sent to the display buffer 24 via the gate _G1 . The time information stored in the display buffer 24 is sent to the display drive circuit 25 and converted into a dot matrix drive signal. Then, the dot matrix display section 26
The above time information is displayed. Further, the time information counted by the counting unit 23 is sent to the alarm circuit unit 27 and compared with alarm time information stored in advance in the alarm circuit unit 27. When the time information and the alarm time information match, a match signal is output to the sound emitting device 28. Furthermore, the alarm time information stored in the alarm circuit section 27 is sent to the display buffer 24 via the gate _G2 . Further, the operation signal of the display mode selection switch _S1 is sent to the one shot circuit 29. This one-shot circuit 29 outputs a one-shot pulse to a mode counter 30 constituted by a quaternary counter each time the display mode selection switch _S1 is operated. This mode counter 30 performs a counting operation every time the one-shot pulse is input, and sequentially outputs a "1" signal to the "0", "1", "2", and "3" lines of the decoder 31. The signal on the output line a of the decoder 31, which is output when the mode counter 30 is "0", is sent to the gate _G1 as a gate control signal.
Further, the signal on the output line b of the decoder 31 that is output when the mode counter 30 is "1" is sent to the gate _G2 as a gate control signal.
Next, the switch S ₂ is a memory selection switch, and the operation signal of this switch is sent to the one shot circuit 32. This one shot circuit 32 outputs a one shot pulse via an AND circuit 33 to a memory selection counter 34 constituted by a ternary counter each time the memory selection switch _S2 is operated. Note that the signal on the output line d of the decoder 31, which is output when the mode counter 30 is "2" and "3", is input to the AND circuit 33 as a gate control signal.

The memory selection counter 34 is a memory selection information storage means that counts one-shot pulses and stores selection information for selecting any one of the first to third memories 35 to 37, which will be described later. Each time a yacht pulse is input, "1" signals are sequentially sent to signal lines f to h. The signals on the signal lines f to h are sent to the display buffer 24 via the gate _G3 . A signal on the output line d of the decoder 31 is inputted to this gate _G3 as a gate control signal. Further, the signal on the signal line f of this memory selection counter 34 is the first memory 35 where the timetable is stored, the signal on the signal line g is the second memory 36 where the telephone number is stored, and the signal on the signal line h is the first memory 35 where the timetable is stored. Third memory 3 where address is stored
7 as a memory selection signal.
Next, the switch S ₃ is a character type selection switch, and the operation signal of this character type selection switch S ₃ is sent to the one shot circuit 38. This one-shot circuit 38 sends a one-shot pulse to the AND circuit 3 every time the character type selection switch _S3 is operated.
9 to a data selection counter 40 consisting of a ternary counter. The AND circuit 39 is supplied with an output line c that is output from the decoder 31 when the content of the mode counter 30 is "2". However, the data selection counter 4
The calculated value of 0 is sent to the data code generator 41. This data code generation section 41 stores codes for numerical data, katakana character data, and alphabetic character data, and the data selection counter 40
These three types of codes are selectively output to the buffer 42 according to the count value. In this case, the data code output from the data code generator 41 is 10
For example, the first character in katakana is A to A.
If it is an English character, data codes A to J are output. Next, the readout switch _S4 is a switch used for both reading out the character data code from the character data code generation section 41 and reading out the data stored in the first to third memories 35 to 37. The operation signal of this switch is sent to the one shot circuit 43. The one shot pulse output from this one shot circuit 43 is output to the decoder 3 when the mode counter 30 is "3".
The output line e output from 1 is output as a read signal to the first to third memories 35 to 37 through the AND circuit 44, and is selected by the memory selection counter 34 as described later. Reads data from memory and displays it. That is, the readout switch S ₄ , the one-shot circuit 43 and the AND circuit 44 operate as readout switch means.

Further, the one shot pulse from the one shot circuit 43 is outputted to the data code generating section 41 via the AND circuit 45. When the one-shot pulse is supplied from the AND circuit 45, the data code generating section 41 generates data for each 10 characters.
Outputs the next character data code.

That is, the readout switch S ₄ , the one shot circuit 43 and the AND circuit 45 operate as next character data readout switch means.

Note that the AND circuit 45 includes the decoder 3
The signal on output line c of No. 1 is input as a gate control signal. Next, switches T ₀ to _{T 9} are data input operation switches consisting of, for example, a numeric keypad,
Operation signals of these switches T ₀ -T ₉ are sent to one-shot circuits 46 ₀ -46 ₉ . The one-shot circuits 46 ₀ to 46 ₉ are connected to the switches T ₀ to 46 9 .
A one-shot pulse is output to the data code selection section 47 when _T9 is operated. This data code selection section 47 associates the 10-character data code sent from the buffer 42 with each of the switches _T0 to _T9 , and sends the data code of the character corresponding to the operated switch to the display buffer 24. . Furthermore, this data code is sent to the first to third memories 35 to 37 via the gate _G4 , respectively, and stored in the memory selected by the memory selection counter 34. That is, the one-shot circuit 46
₀ to 46 ₉ , data code selection section 47 and gate G ₄
operates as a data storage control means.

The 10-character data code stored in the buffer 42 is sent to the display buffer 24 via gate _G5 . The signals on the output line c of the decoder 31 are input to the gates _G4 and _G5 as gate control signals, respectively. Thus, data is sent to the display buffer 24 from the first memory 35 through the gate _G6 , from the second memory 36 through the gate G7, and from the third memory ₃₇ through the gate _G8 . connected to. 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, operate the display mode selection switch S ₁ to set the mode counter 30.
When set to "1", the alarm display mode is activated. That is, by output line b, gate G ₂
opens and the alarm time information "12:30 p.m." set in the alarm circuit section 27 is displayed.
4. The signal is sent to the dot matrix display section 26 via the display drive circuit 25 and displayed as shown in FIG. Note that when the current time information counted by the counter unit 23 matches the alarm time preset in the alarm circuit unit 27, a coincidence signal is output from the alarm circuit unit 27 to the sound emitting device 28, and the alarm is emitted. be heard. Then, operate the display mode selection switch _S1 and set the mode counter 30 to "2".
(data write mode). Then, the AND circuits 33,
39, 45, and gates _G3 to _G5 open, respectively. Next, the first to third memories 35, 3
Which of the memories 6 and 37 data is written to is determined by operating the memory selection switch _S2 and setting the count value of the memory selection counter 34 to a predetermined value. In other words, when the count value of the memory selection counter 34 is "0", the first memory 35, and when this count value is "1", the second memory 3
6. When this count value is "2", the third memory 37
is selected. Here, as described in the explanation of the above configuration, in this embodiment, the first
A timetable is written in the memory 35, a telephone number (including name) is written in the second memory 36, and an address (address) is written in the third memory 37. Further, the count value of the memory selection counter 34 is sent to the display buffer 24 via the gate _G3 . 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", an address mark (FIG. 7B) is displayed at the upper right of the dot matrix display section 26 to clearly indicate which of the first to third memories 35 to 37 has been selected. Now, a case will be described in which, for example, the memory selection counter 34 is set to "1" and the second memory 36 is selected, and a telephone number and a name "243-1513GEORGE" are written in the second memory 36. First, the data selection counter 40 is set to “0”.
When the data selection counter 40 is set, the count 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 operation signals of the switches T ₀ to T ₉ are sent to the data code selection section 47, and the numerical data codes corresponding to the switches T ₀ to T ₉ are sent to the display buffer 24, as shown in FIG. Is displayed. Next, when inputting the name "GEORGE", the character type selection switch _S3 is operated to set "2" in the data selection counter 40. Then, the count value of this data selection counter 40 is "2".
is sent to the data code generator 41. As a result, the data codes for alpha bets "A" to "J" are sent from the data code generating section 41 to the buffer 42 and the display buffer 24, respectively.
The 10 alphanumeric characters "A" to "J" are displayed on the lower row of the dot matrix display section 26.
Displayed corresponding to T ₀ to T ₉ . As a result, the data that is input when switches T ₀ to T ₉ are operated is displayed above each key. And “6”
When the keys ``4'' and ``4'' are operated in sequence, the operation signals are sent to the data code selection section 47 to select the data codes for the alphabets ``G'' and ``E''. And these alpha alphabets “G”
The data code for "E" is displayed in buffer 24.
The data is sent to the dot matrix display section 26 (FIG. 5), and is also written into the second memory 36. In FIG. 5, the position where the "↓" display 26b is displayed indicates that the next input data will be displayed. This "↓" display body 26
b 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 of the readout switch _S4 is sent to the data code generating section 41 via the AND circuit 45, and the data codes of the next 10 characters of alphabets "K" to "T" are sent to the buffer 42. Then, "K" to "T" are displayed at positions corresponding to the switches _T0 to _T9 , respectively (FIG. 6). Here, the alphanumeric character "O" is input by operating the "4" key. The data code for the alphabet "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. Hereinafter, in the same way, alphabets "R" and "G"
Enter "E". In this way, the telephone number "243-1513" and the name "GEORGE" are stored in the second memory 36. Also, if you want to enter your name in katakana characters, click the character type selection switch.
Set the data selection counter 40 to "1" by operating _S3 . This data selection counter 40
The count value "1" is sent to the data code generation section 41. As a result, data codes for 10 katakana characters "A" to "K" are sent from the data code generating section 41 to the buffer 42. And these 10 katakana characters "a" to "ko"
The data code for the characters is sent to the display buffer 24 and displayed on the dot matrix display section 2 as shown in FIG.
6. Furthermore, each time the readout switch _S4 is operated, the display is switched every 10 characters, such as "sa" to "to" and "na" to "ho", making it possible to input in katakana. 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, display mode selection switch S ₁
to set the mode counter 30 to "3". As a result, the output line e from the decoder 31 becomes a signal "1", and the AND circuit 44 and the gate
Gates G ₆ to G ₈ open respectively. Next, the memory selection switch _S2 is operated to set the count value for the first to third memories 35 to 37 in the memory selection counter 34. Now, for example, the second memory 36
When displaying the telephone number stored in the memory selection counter 34, the memory selection counter 34 is set to "1". Next, when the read switch _S4 is operated, a one shot pulse is outputted to the second memory 36 via the AND circuit 44. As a result, the address of the second memory 36 is updated every time the readout 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.
