JPS58132830A - Treadle input device - Google Patents

Abstract

PURPOSE:To make it possible that even a physically handicapped person who has trouble in the hand inputs data to a computer easily, by dividing the display part of a cathode-ray tube to a display part for retrieval characters and a cursor and an input character display part. CONSTITUTION:A cathode-ray tube display part 2 is provided in the upper part of a device body 1, and a treadle switch operation part 3 is provided in the lower part. The display part 2 is divided to a retrieval character display part A, where retrieval characters including alphabets, numbers, symbols, and Kana (Japanese syllabary) characters and a cursor S which designates one optional character and is moved freely are displayed, of the upper half and an input character display part B, where a sentence generated by characters designated by the cursor S is displayed, of the lower half. The operation part 3 is provided with a horizontally and vertically operatable switch 4 for cursor movement and a push-button switch 5 for input, and these switches can be operated by left and right feet of the operator, respectively. The switch 4 is operated to move the cursor S to a desired character of the display part A, and the switch 5 is operated to display this character on the display part B, thus inputting a sentence.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a foot-operated input device that allows a physically handicapped person who is unable to use his hands to input information into a computer, typewriter, etc. using only his feet.

Generally, when operating switches with your foot, the number of switches that can be operated is limited, so it was previously impossible to input information with many types of characters (including numbers and symbols), as with computers and typewriters. is. SUMMARY OF THE INVENTION An object of the present invention is to provide an input device that can be easily operated with the foot by reducing the number of operation switches as much as possible, and that uses a large number of characters.

FIG. 1 is an external view of a device showing an embodiment of the present invention.
-, a cathode ray tube display section 2 is provided in the upper part of the device main body 1, and a foot-operated switch operation section 3 is provided in the lower part. As shown in FIG. 2, the cathode ray tube display section 2 is
The screen is divided into upper and lower halves, with the upper half serving as the search character display area A and the lower half serving as the input character display area B. In this embodiment, the search characters are alphabetic letters, numbers, symbols, and katakana. However, it may be composed of alphanumeric characters, numbers, and symbols, or it may be composed of kanji, hiragana, numbers, and symbols. Further, the search character display section A displays a movable cursor S that can indicate any one character. The input character display section B displays a sentence composed of sequentially input characters. The foot-operated switch operation section 3 is provided with a cursor movement switch 4 that can be operated forward, backward, left and right, and a push button type input switch 5, which can be operated with the left and right feet, respectively. The cursor movement switch 4 includes a lever which is normally held at the central return position by springs from all sides, and a lever located at the front, rear, left and right sides of the lever. When this lever is pressed in one direction, a corresponding limit switch is operated to move the cursor in a predetermined direction at a constant speed.

To explain the operation of the large-foot input device of the present invention configured as described above, the operator first searches for the character to be input from among the group of search characters on the display section A, and operates the cursor movement switch 4 with his right foot. Move the cursor S to the desired character position. At this time, while the cursor movement switch 4 is being pressed, the cursor S continues to move in a predetermined direction, and when the operator relaxes his foot, the cursor movement S stops. When the cursor S comes to a desired position, the operator presses the input switch 5 with his left foot and inputs the character selected by the cursor S. The characters thus input are sequentially displayed on the input character display section B for confirmation.

According to the present invention, as described above, the cathode ray tube display section is divided into upper and lower halves, and the search character group and cursor are displayed on one side, and the input sentence is displayed on the other side. , even if there are many types of characters used, the operator can reliably select any character while visually checking the character, and the switch operation section has a cursor movement switch and input switch (and some The switch has the advantage that it is extremely easy to operate the switch with the foot, since all that is needed is a changeover switch (changeover switch).This also has the advantage of making it possible to input input into a combiator or typewriter using the foot, which was previously difficult. .
