Description

Computer keyboard with scientific calculator and electronic equipment

Technical Field

The utility model relates to a computer peripheral hardware and human-computer interaction technical field especially indicate a take computer keyboard and electronic equipment of scientific calculator.

Background

The Win10 operating system is a PC operating system with the highest market share at present, the Win10 calculator is used as a standard application program of the Win10 operating system, and the Win operating system not only has three modes of a common calculator, a scientific calculator and a programmer calculator, but also has a powerful 'converter' function and can complete various unit conversions and currency value conversions; in 2020, Microsoft has introduced a win10 calculator graph function mode, supports graph functions such as trigonometric functions, linear algebra and equation sets, and can view graph changes and perform scroll switching after inputting expressions. Although the PC with win10 calculator has powerful function and is far beyond independent scientific calculator, the keyboard of the PC has only four basic operator keys of + -/and lacks various function operation and function keys of the scientific calculator. If the computer keyboard is classified according to the number of key areas, the computer keyboard is generally divided into a three-key-area keyboard of a desktop computer and a single-key-area keyboard of a notebook computer; the functional division is divided into four parts: the main keyboards, the QWERTY layout alphabet keyboard (also called typewriter keyboard), the function keys (F1-F12), the 3 x 3 numeric keypad, the edit key (cursor control key). At present, the following notebook computer keyboards all adopt single key regions, an independent 3 x 3 numeric keyboard is generally lacked, and due to space limitation, a 3 x 3 numeric keypad is superposed on the right half part of a main keyboard, is multiplexed with letter keys U IO J K L and is converted by NumLock (or Fn + NumLock); because the letter keys are arranged diagonally, this overlapping approach results in a 3 x 3 numeric keypad on a notebook computer that is inconvenient to use, poor in usability and user experience. In fact, few people use the obliquely arranged 3 x 3 numeric keypad, which is not in line with the use habit of people, is easy to operate by mistake and further cannot realize touch typing numeric input. Many current notebooks and ultrabooks completely abandon the multiplexed 3 x 3 numeric keyboard and only keep the 1 x 10 numeric keyboard. In conclusion, the user experience is not satisfactory whether the digital keyboard is a 3X 3 digital keyboard which is obliquely overlapped and multiplexed or a digital keyboard which is arranged in a 1X 10 mode, and the usability is far from being compared with that of a separate digital keypad of a desktop computer. The technical proposal of the utility model successfully solves the problems of the computer keyboard that the strong functions of the win10 calculator carried by the PC can be fully exerted by ensuring that the computer keyboard not only has a 3 x 3 numeric keyboard with good usability, but also has various function operations and functional keys of a scientific calculator.

Disclosure of Invention

The utility model discloses a main aim at provides the interior nine palace check computer keyboard who takes various function operations and function button of scientific calculator, solves the problem that exists among the prior art to be suitable for the practicality more, obtain better user experience, and have the industrial value of utilizing.

The foundation the utility model provides a take computer keyboard of scientific calculator, include:

QWERTY layout letter keyboard + interior Sudoku 3 Tmax 3 digital keyboard;

function operation and function keys of a scientific calculator;

the purpose and the technical proposal of the utility model can be further realized by adopting the following technical measures.

Inside the single-area computer keyboard, special keys are adopted to replace standard keys, transition and conversion from oblique arrangement to vertical arrangement are realized, a vertically arranged inner nine-grid 3 multiplied by 3 numeric key area is obtained, a numeric keypad is superposed on the vertically arranged inner nine-grid 3 multiplied by 3 numeric key area, is multiplexed with the key area, and is converted through a NumLock key;

various function operations and function keys of the scientific calculator are mapped to other key positions on the periphery of the inner squared figure 3H 3 numeric keyboard, the key positions are superposed and multiplexed, and when the win10 calculator runs in a scientific calculator mode, the key positions realize various function operations and function keys.

On the other hand the utility model also provides an electronic equipment, include:

a main body device;

a processor provided in the main body apparatus;

a computer keyboard adopts the computer keyboard with the scientific calculator and is connected with the processor.

Compared with the prior art, the beneficial effects of the utility model are that: the computer keyboard with the scientific calculator is provided, so that the computer keyboard not only has a well-available Indoku 3-3 numeric keyboard, but also has various functional operations and functional keys of the scientific calculator, the powerful functions of the win10 calculator of the PC are fully exerted, and the human-computer interaction efficiency and the user experience are improved. The common scientific calculator cannot reserve, copy and paste the operation process and the operation result into other application programs, while the scientific calculator carried by the PC can reserve, copy and paste the operation process and the operation result into other application programs, and the key point is to provide a high-efficiency human-computer interaction keyboard.

The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood and to be implemented according to the content of the description, the following detailed description is given with reference to the preferred embodiments of the present invention and the accompanying drawings.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 shows a conventional single-keypad notebook computer keyboard, which is a horizontal Enter American keyboard, with a 3X 3 numeric keypad obliquely superimposed on letter keys U IO J K L, multiplexed with the letter keys, and converted by Fn + NumLock. This solution, although having a 3 x 3 numeric keypad, is poorly available, and people prefer to use the 1 x 10 numeric keys, and almost rarely use the 3 x 3 numeric keypad. The scheme is mainly adopted by 14-hour American notebook computers.

FIG. 2 shows an apple American notebook keyboard, single key pad, cross Enter. Apple gives up the reuse scheme of numeric keypad used by most notebook computers in the past, there is no 3 x 3 numeric keypad superimposed on letter keys at all, and because there is no 3 x 3 numeric keypad available, only 1 x 10 numeric keys can be used for numeric input. Obviously, the 1 x 10 numeric keys are less efficient than the 3 x 3 numeric keys in continuously inputting numbers and cannot bring good user experience. The keyboard scheme is adopted by notebook computers and tablet computers of apple company, and the keyboard scheme is also widely adopted by super notebook computers of 11 hours-13 hours of other companies.

Fig. 3 shows the first embodiment of the present invention.

Fig. 4 shows a second embodiment of the present invention.

Detailed Description

Fig. 3 shows an embodiment 1 of the present invention, which is directed to a 14-hour american type horizontal enter single-key-zone notebook computer, wherein a 1.25-fold special key is used to replace the standard keys O, M and <, so as to realize the transition and conversion from slant arrangement to vertical arrangement, and obtain a vertically arranged inner nine-grid 3 h 3 numeric keypad, which is superimposed on the vertically arranged inner nine-grid 3 h 3 numeric keypad, and is multiplexed with the keys in the zone and converted by a NumLock key. Various function operations and function keys of the scientific calculator are mapped to other key positions on the periphery of the inner squared figure 3H 3 numeric keyboard, the key positions are superposed and multiplexed, and when the win10 calculator runs in a scientific calculator mode, the key positions realize various function operations and function keys.
