Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a right-handed left-handed keyboard device in which the left and right numeric keypads are interchanged so that both right-handed and left-handed operators can easily perform input operations.

[0002]

2. Description of the Related Art In a conventional keyboard for input operation of a personal computer or the like, keys for editing functions are arranged centering on character keys. Further, numeric keys 1 to 10 and a ten-key portion for scrolling are provided with editing function keys. It is generally arranged and provided on the right side of the section. In addition, a keyboard device is used in which an independent separate ten-key portion can be additionally arranged on the keyboard body. In this case, the numeric keypad is arranged near the right side of the keyboard, and the cable is connected to the keyboard body for use.

[0003]

As described above, in the conventional keyboard device, the positional relationship is considered so that the right-handed operator can easily perform the input operation. Therefore, there is a problem that the input operation is not easy for the left-handed operator.

When an independent ten-key portion is arranged near the right side of the keyboard body for use, the ten-key portion is small and the ten-key portion cannot be fixed to the keyboard. Therefore, there is a problem that the input operation becomes difficult because the user moves during a high-speed input operation such as blind touch.

The present invention is intended to solve such a problem and allows both right-handed and left-handed operators to easily perform an input operation, and prevents dust from adhering or inserting, and the numeric keypad. It is an object of the present invention to provide an excellent right-handed left-handed keyboard device in which the parts can be easily attached to and detached from the keyboard body, and the electrical connection therebetween can be easily made.

[0006]

In order to achieve this object, a keyboard device for a right-handed and left-handed person according to the present invention is arranged at least on a keyboard body and one of a left end portion and a right end portion of the keyboard body. And a ten-key portion having a numeric string input key, and a detachable mechanism portion for attaching and detaching the ten-key portion to the keyboard body at both left and right end portions of the keyboard body and both left and right end portions of the ten-key portion.

In addition to this structure, a removable dustproof cover is provided at the end of the keyboard main body and / or the numeric keypad where the keyboard main body and the numeric keypad are not joined.

In addition to these configurations, a fixing mechanism portion forcibly fixing the keyboard main body, the ten-key portion, and the dustproof cover at the time of mounting them, and the fixing state is released by pressing at least one button after mounting. It is a configuration including a fixing release mechanism section.

Further, in addition to these constitutions, at the left end and / or the right end of the keyboard body and the ten-key part,
Connect when attaching and detaching the numeric keypad to the keyboard body,
This is a configuration including a connector for electrical connection that is not connected.

[0010]

With such a structure, the keyboard device for a right-handed and left-handed person according to the present invention has a detachable mechanism for attaching and detaching the ten-key portion to the keyboard body and the left and right end portions of the keyboard body. Since the portion is provided, the numeric keypad portion can be arranged at either of the left and right end portions of the keyboard body, so that both right-handed and left-handed operators can easily perform an input operation.

Further, since the detachable dustproof cover is provided at the end of the keyboard body and / or the tenkey portion where the keyboard body and the tenkey portion are not joined, attachment and insertion of dust can be prevented.

Further, a fixing mechanism portion forcibly fixing the keyboard body, the numeric keypad portion, and the dustproof cover at the time of mounting, and a fixing releasing mechanism portion for releasing the fixed state by pressing at least one button after mounting and releasing it. Since the key is provided, the keyboard body and the ten-key part can be easily attached and detached.

Further, at the left end and / or right end of the keyboard body and the numeric keypad portion, a connector for electrical connection which is connected or disconnected when the numeric keypad portion is attached to or detached from the keyboard body is provided. Since this is done, the electrical connection between the keyboard body and the numeric keypad can be facilitated.
