Abstract

PURPOSE:To quickly select character data by reading out the character data in the order of the Japanese syllabary or the leading character of each line by the different operations of an operating device. CONSTITUTION:When a rotary switch 1 is slowly rotated at a speed less than a prescribed speed, the output of a detecting circuit 2 is turned to ''1'' and a gate circuit 16 is opened. A pulse from the rotary switch 1 is outputted from a pulse controlling circuit 3 as it is and supplied to a counter. Therefore, a character data is read out in the order of the Japanese syllabary in every generation of one pulse from the rotary switch 1. When the rotary switch 1 is rotated faster than the prescribed speed, a counter 11 is kept at reset status by an output from the detecting circuit 2, and a gate circuit is opened, so that a pulse from the pulse controlling circuit 3 is supplied to a counter 12 and the leading character of each line is successively read out from a storage circuit 91.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a character selection device for characters such as kana characters.

Conventionally, in a device for selecting and inputting, for example, 50 syllabary characters, a key is provided for each character, resulting in a keyboard that takes up a large area and becomes expensive.

Therefore, the present invention provides a simple and inexpensive character selection device that can quickly select character data using a single operating device.

An embodiment of the present invention will be described below based on the drawings. 1st
In the figure, reference numeral 1 denotes a riece type rotary switch, and 2 a rotation speed detection circuit for determining whether the rotation speed is faster or slower than a predetermined speed. Reference numeral 3 denotes a pulse control circuit that controls pulses from the switch 1 in accordance with the output from the detection circuit 2. 4
5 is a set switch, 5 is a reset switch, and 6 is a pulse generation circuit that generates a control pulse at the time of reset F. 7 is a selection circuit consisting of a shift register that selects a character digit;
81-8n are latch circuits, 91-9! L is 50 each
In a storage circuit such as a ROM that stores phonetic and character data, the upper 4 bits 1-A6 select A line, power line,...on, and the lower 3 bits AO-A2 select the row direction. do.

10 is a single digit display device.

' 11 and 12 are counters for specifying addresses of the memory circuits 91 to 9n, 13 is a 7-lip 70-lip circuit, 1
4 to 20 are gate circuits, and 21 is a differential circuit.

・Next, the operation will be explained. First, operate the reset switch 5 to reset the shift register 7, latch circuits 81 to 8n, and counters 11 and 12 with a reset pulse from the terminal R, set the 7-lip 70-tub circuit 13, and connect the D input of the selection circuit 7 to @ Hold at 11. The reset pulse is set so that pulses are generated in this order from the terminals R/ and R1 of the pulse generating circuit 6. First, a pulse from terminal R' triggers the selector, path 7, whose first bit is @1'
become. Then, the 7 rip 70 tube circuit 13 is reset by the pulse from the terminal R', and the latch circuit 81 is selected by the output of the 0 selection circuit 7, in which the D input of the selection circuit 7 is inverted to @0'', and the latch circuit 81 is selected by the output of the 0 selection circuit 7, which inverts the D input of the selection circuit 7 to The output passes through a latch circuit 81 and is supplied to a storage circuit 91.

Since the counters 11 and 12 have now been reset, the character "A" in the first row of the A row is selected from the memory circuit 91 by the output thereof, and is displayed in the first digit of the display device 10.

Therefore, when the rotary switch 1 is rotated slowly below a predetermined speed, the output of the detection circuit 2 becomes @1' and the gate circuit 16 is opened. Further, the pulses of the rotary switch 1 are generated as they are from the pulse control circuit 3 and are supplied to the counter 11.

Therefore, every time one pulse is generated from the rotary switch 1, the letter "i" is generated.

They are read out in the order of the 50 syllabary characters: ``tsu'', ``tech'', ``o'', ``power'', ``ki'', and so on.

Further, when the rotary switch 1 is rotated faster than a predetermined speed, the counter 11 is held in a reset state by the output of the detection circuit 2, and the gate circuit 17 is opened, and the pulse from the pulse control circuit 3 is supplied to the counter 12, and the memory 1
From 11691, the 50-sound "a" line, "ga j line...
The first character of ``power''.

"Su", "Yu", etc. are read out in this order.

At this time, the pulse control circuit 3 generates a pulse that is 1/N (N: 2, 3, . . . ) of the pulse from the rotary switch 1. That is, since the pulse generation speed from the rotary switch 1 is fast, if the pulses were supplied as they were to the counter 12, the readout speed would be too fast and the characters would become illegible. /H to read out characters at a readable speed.

, Since the characters are read out in the above manner, any character can be read out quickly. For example, reading the character "nu",
To remove it, rotate rotary switch 1 quickly to
After making selections in the order of ``Power'', ``Su'', ``Yu'', and ``Su'', slowly rotate rotary switch 1 to select ``SuJ, r''.
You just have to select in this order: 2J, Rnu.

After selecting the desired character in this way, the set switch 4 is operated to trigger the selection circuit 7, and the outputs of the counters 11 and 12 are latched in the latch circuit 81 by the fall of the first bit, and the output of the second bit is latched by the latch circuit 81. Latch circuit 82 is selected. Furthermore, the fall of the pulse from the set switch 4 generates a differential pulse from the differentiating circuit 21, and the counters 11 and 12 are reset. Then, in exactly the same manner as above, one character in the second digit is selected and latched by the latch circuit 82.

Thereafter, select characters up to the nth digit in the same manner.

In the above embodiment, the rotation speed of the rotary switch is 50. Although the selection is made in phonetic order or sequentially from the first letter of each line, the selection order may be changed depending on the direction of rotation.Also, instead of using a rotary switch as described above, a push switch may be used. The selection order may be changed depending on the length of the pressing time using
For example, the pressing time is counted, and if the pressing is released in a short time, the character data is read out in alphabetical order each time the pressing is released, and if the pressing continues for a certain period of time, each line is read out with a clock pulse at a predetermined period. It selects the first characters in sequence.

As described above, according to the present invention, it is possible to quickly select kana character data with a single operating device, the number of switches can be significantly reduced compared to the conventional one, and the product is inexpensive and compact. .
