Problems solved by technology

[0002] At present, general mobile phones use numeric keypads as character input, and there are three problems: one, the area of ​​the data keypad is relatively large
It is easy to enter wrong characters if you don't look with your eyes
Touch typing can only be achieved after a period of practice, so it is inconvenient for people with ordinary skills to operate
3. When entering A-Z letters, you need to press the key repeatedly
If it is used for a large number of character input, such as: the input of 11-digit long phone

Embodiment Construction

[0090] in figure 1 In the housing (1), there is a hole (2), and the hole (2) has a movable button (3). The size of the hole (2) can make the button (3) move up, right, down, and left. The shell is marked with 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, #, *, a-z and other signs. The buttons are marked with OK, CANCEL, MENU and other signs.

[0091] in figure 2 In the housing (1), there is a hole (2) in the shape of a "+" shape, and the "+" shape of the hole can locate the moving direction of the button (3). Avoid the button (3) from appearing to move to the "upper left", "lower right" and other oblique directions, causing two switches to be activated at the same time, resulting in input errors.

Abstract

The device composed of only one pushbutton can input a character among 1-9, A-Z by one time of operation of pushing the pushbutton. The device includes a mechanical motion set and an electric signal conversion set. Button in the mechanical motion set can be moved in up, down, left and right directions as well as can control additive switch. One time of operation of pushing button can generate sequence of electric signal from multiple switchers. The electric signal conversion set converts switch sequence to electric signals, which represent characters. The invention is applicable to input device of hand held devices such as handset, PDA etc.

Description

Technical field [0001] The invention relates to a character input device, in particular to a character input device used in handheld devices such as mobile phones and PDAs. Background technique [0002] At present, general mobile phones use numeric keyboards as character input, and there are three problems: 1. The data keyboard has a large area. The data keyboard generally has twelve keys 0-9, *, #. If the area is less than 2×2CM, the fingers cannot be accurately positioned because of the small distance between the keys, and incorrect keys may appear. If the keyboard area is large, the volume of the phone must be larger and the screen smaller. 2. People with general skills need to look at the position of the fingers and the keyboard with their eyes to input characters correctly. If you don’t look at it with your eyes, it’s easy to enter wrong characters. Blind typing can only be achieved after a period of practice, so it is inconvenient for people with general skills to operate. ...
