Problems solved by technology

[0023] However, it can be seen that in order to quickly input, the keyboard of the steno recorder needs to mobilize all fingers, which reduces the flexibility of operation and limits the further miniaturization of the keyboard size.
Moreover, by analyzing the keyboard of the above-mentioned speed recorder, it can be known that although it can input characters more efficiently and quickly than the traditional keyboard, it adopts the keystroke mode of multi-key and strikes, and both hands can complete the entry of two syllable codes once, but due to its keys The arrangement is relatively monotonous, there are defects in misoperation and inconvenient operation, and fast input requires long-term training

Embodiment 1

[0174] Such as figure 1 As shown, a top view of the keyboard 100 according to the first embodiment of the present invention is shown.

[0175] The keyboard 100 is composed of a base 10 and a concave first key 1 , a rectangular second key 2 , a concave third key 3 , and a rectangular fourth key 4 located on the same surface of the base. Wherein the two arms 1a and 1b of the first key are opposite to the two arms 2a and 2b of the third key and separated by a certain distance, wherein the distance can be as small as possible, as long as they do not interfere with each other, the second and fourth keys are in the Surrounded by the first and third keys, the distances from the three inner surfaces of the first and third keys can be as small as possible, as long as they do not interfere with each other.

[0176] The advantage of the keyboard structure set up in this way is that its volume can be very small, for example, it can be 2cm×2cm. When held in the hand, for example, the fo...

Embodiment 2

[0194] In this embodiment, the working process of the first, second, third, and fourth keys is the same as that of Embodiment 1, the difference lies in the shape and position relationship of the aforementioned keys. Such as Figure 4 As shown, wherein the first, second, and third bonds are fan-shaped keys (certainly not limited to fan-shaped keys) arranged in the circumferential direction, and the fourth key is a ring key surrounding the first, second, and third bonds, these The keys are spaced apart from each other so as not to interfere with each other's actions. The advantage of the keyboard is that it is very convenient for one-finger operation, and the probability of mispressing is lower.

Embodiment 3

[0196] exist Figure 5 shows the keyboard structure according to the third embodiment of the present invention.

[0197] Wherein, the first, second, third, and fourth keys 1, 2, 3, and 4 are arranged in a matrix form in a counterclockwise direction, and are separated from each other by a certain distance. Another first input key 1' is set outside the second and third keys at a predetermined distance, so that a single finger can simultaneously trigger the first and third key combinations or the first, second, and third key combinations; similarly , on the outside of the third and fourth keys and at a certain distance, another second input key 2' is set so that a single finger can trigger the second and fourth key combinations or the second, third, and fourth key combinations at the same time; The outside of the first and fourth keys is provided with another third key 3' at a certain distance so that a single finger can trigger the first, third or first, third and fourth combin...

Abstract

An input device consists of electronic circuit and one input unit set as each input unit including the first switch, the second switch, the third switch and the fourth switch. It is featured as usingelectronic circuit to detect state of said switch and connecting four switches to be switch enabling to use single finger to trigger any combination of the four.

Description

technical field [0001] The present invention relates to an information input device, more specifically, to a small-sized keyboard which can greatly reduce the number of keys and the size of the keyboard. Background technique [0002] Data input is an essential function of various electronic devices. Among most of the current input methods, keyboard input is still in the leading position in terms of speed and accuracy. As electronic devices continue to be miniaturized, input devices are also shrinking in size. [0003] In the prior art, the miniaturization of the keyboard has certain limitations. First of all, in order to enable the user to conveniently input with fingers, the size of the keys should not be too small. If the keys are too small, they cannot be operated with fingers, or they are prone to misuse. Secondly, in order to be able to input enough numbers and characters, it is necessary to ensure that the keys have a sufficient number of keys. For two aspects are r...
