ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a keyboard having a protective lid, especially to a keyboard, which has the functions of dust-proofing, protection, support and keyboard mounting.
BACKGROUND OF THE INVENTION
The prior art keyboard having a protective lid has only functions of dust-proof and protection. For example, the keyboard having a protective lid disclosed in Taiwan Patent Publication No. 219170 and No. 313283 has only functions of dust-proof and protection; and does not provide supporting function and occupies considerable space.
As shown in
FIGS. 1 and 2
, another prior art keyboard having a protective lid disclosed in U.S. Pat. No. 6,108,200 has a socket
65
on rear side of a keyboard
60
and electrically connected to the internal circuit of the keyboard
60
. A portable electronic device
4
such as a mobile phone or a PDA (personal digital assistant) is inserted into the socket
65
. The keyboard
60
has a sliding supporting stage
70
on rear bottom side thereof. The supporting stage
70
has an unfoldable lid
75
.
However, in above-mentioned keyboard having a protective lid, the lid
75
cannot be used as a keyboard mounting to let the keyboard
60
be inclined with specific angle. The whole height of the keyboard
60
will be increased thereby.
SUMMARY OF THE INVENTION

To achieve above object, the present invention provides keyboard having a protective lid having a keyboard body, a linkage board and a lid. The keyboard body has an accommodation space on rear side thereof and the accommodation space has two pivotal holes on two lateral sides thereof. The linkage board has a front end pivotally connected to the keyboard body. The linkage board has a rear end pivotally connected to a front end of the lid such that the lid can be swung to a backside of the keyboard body and functioned as a mount of the keyboard body to let the keyboard body be inclined to a specific angle.
