Description

keyboard

The utility model relates to a keyboard, in particular to a BACK SPACE key, an ERASE key and/or an ENTER key of the keyboards of computers, electronic typewriters (ELECTRICTYPEWRITER) and other equipment.

The keyboard of a modern computer or electronic typewriter includes a plurality of numbers and letters (Alphanumeric) keys. The return key can not only return the cursor to a certain position, but also complete the delete function during the return process. The delete key is to delete the content data at the position of the cursor. And the input key is to send the typed data into the computer system, and completes the action of changing the line (next line).

However, the existing keyboard has some ERGONOMICS deficiencies in operation, so it is not very convenient for the user to operate the return key, the delete key or other function keys. Therefore, there is a new key layout (layout) design, and obtained such as US Patent No. 5,143,462 and No. 4,974,183 respectively.

In addition, when people are doing word processing, the purpose of using the arrow keys, such as ↑, ←, ↓, → keys, is to change the previously mistyped words in addition to moving to the location and inserting new content. At this time, according to the prior art, the right hand must be moved to the return key to move forward and delete at the same time, or move to the delete key to perform backward movement and delete at the same time. The location can only be achieved, which is very inconvenient.

The purpose of this utility model is to provide a keyboard, which uses a new key arrangement method, and the user only needs to move the finger in a small range to operate between the direction key, the return key and the delete key.

The purpose of this utility model is achieved in that a keyboard is provided, which includes: a plurality of numeric/character keys; Area; a return key is arranged in the area adjacent to the direction key, and the user can move fingers between the direction key and the return key without moving the palm.

The utility model also provides a keyboard, which includes: a plurality of number/character keys; a plurality of direction keys, which are right, left, up and down direction keys, which constitute a direction key area; a delete key is arranged on In the area adjacent to the direction key, the user can move his finger between the direction key and the delete key without moving his palm.

The advantage of the device of the utility model is that it can save the time for the user to switch fingers back and forth when editing text.

Below in conjunction with accompanying drawing, describe embodiment of the present utility model, wherein:

Fig. 1 is a schematic diagram of the key position arrangement of the existing keyboard;

Fig. 2 is a figure of an embodiment of the utility model;

Fig. 3 is another embodiment figure of the utility model.

An embodiment of the utility model as shown in Figure 2, has direction key near the right side of input key (ENTER), as ↑, ←, ↓, → four keys, this arrangement and existing keyboard shown in Figure 1 same.

But the utility model arranges a return key 21 and a delete key 23 at the adjacent position of direction key. The design of the embodiment described in Fig. 2 is that the return key 21 is positioned at the top of the ← key and the left side of the ↑ key, and the delete key 23 is positioned at the right side of the ↑ key and above the → key. But it should be known that under the spirit of the present utility model, the opposite arrangement (not shown) can also be made. It can be seen from FIG. 2 that the user does not need to move the palm, but only moves five fingers to switch between the direction key, the return key and the delete key. This is an ergonomic design.

In the embodiment shown in FIG. 3 , in addition to the return key 21 and the delete key 23 shown in FIG. 2 , an input key 22 is added below the arrow keys. Therefore, when finishing some editing work and wanting to switch to the next line, the input key 22 can be easily pressed by moving the fingers in a small range without moving the palm to the existing input key position to change the line.

With the utility model, after using the direction keys, the user can immediately use the return key or the delete key without moving the palm of the hand for a large distance.

By means of the utility model, the eyes of the user do not need to leave the typed document to look for the return key or the delete key, thereby speeding up the typing speed.
