JPH0217729A - Keyboard input device - Google Patents

Abstract

PURPOSE:To enable two kinds of characters/marks to be inputted by providing several stages of contacts of a keyboard, and changing the depth of the touch of the keyboard. CONSTITUTION:When a character/mark input key 6 is depressed, an arm 8 is rotated centering a fulcrum 7, and an endpoint A9 is brought into contact with the contact B10, then, a first character/mark can be inputted. When the key 6 is depressed more deeply, the endpoint A9 is brought into contact with the contact C11, and a state where the character/mark can be inputted as depressing a shift key not shown in figure is generated, then, a second character/ mark can be inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard input device, and particularly to a keyboard input device in which character/symbol input using a shift key can be changed by the depth of the keyboard touch.

[Conventional technology]

Conventionally, inputting characters and symbols using a keyboard input device requires 1
Two types of characters/symbols can be input by distinguishing between them using one character/symbol key, but this distinction was made depending on whether or not the shift key was pressed when pressing the character/symbol key.

[Problem to be solved by the invention]

In the conventional input method described above, two types of characters/symbols are inputted separately by pressing the shift key, so if there are many characters/symbols to be input while holding down the shift key, the inputting person's finger freedom is reduced. The disadvantage is that it takes away a lot of information and is inconvenient to operate.

[Means to solve the problem]

The keyboard input device of the present invention is characterized in that two types of characters/symbols can be input by distinguishing them depending on the depth of the keyboard touch of the inputting person.

Furthermore, it has the feature that it can be distinguished by the shift key as in the conventional case.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention.

The keyboard input device l is a conventional character/symbol input key-2.
and a shift key 3, and a mode switching key 4. The mode switching key 4 is a key for switching whether to distinguish two types of characters/symbols from each other depending on the depth of the keyboard touch, and when a distinguishing input is made, the confirmation lamp 5 lights up.

FIG. 2 is a sectional view of the character/symbol-filled key 2 shown in FIG. 1. When the key 6 is pressed, the arm 8 rotates around the fulcrum 7, the end point A9 comes into contact with the contact BIO, and the first character/symbol is input. However, by pressing the key 6 more deeply, the end point A9 comes into contact with the contact point C1l, and while the shift key is pressed, a character/symbol is entered, and a second character/symbol is input.

If the mode switching key 4 in FIG. 1 is turned off, even if the end point A9 contacts the contact C1l, the contact BIO
The condition shall not be different from the state in which the object is in contact with the object.

Further, if the shift key 3 is pressed while the mode switching key 4 is on, if the end point A9 contacts the contact BIO, the second character/symbol will be input, and the state will not change even if it contacts the contact C1l.

FIG. 3 is a cross-sectional view of another embodiment of the invention.

When the key 6 is pressed, the arm 8 rotates about the fulcrum 7, and the end point A9 contacts the node D12 and then the node E13. While touching node D12, the time until contacting node E13 is measured. If the value is larger than a certain value, the first character/symbol is input, and if it is smaller, the second character/symbol is input.

This embodiment has the advantage that individual differences in keyboard touch can be compensated for by making the above constant value variable.

〔Effect of the invention〕

As described above, the present invention has the effect of allowing two types of characters and symbols to be entered depending on the depth of the keyboard touch by providing several levels of contact points on the keyboard.
