Summary:PURPOSE: A keyboard capable of folding is provided to carry the keyboard and secure a convenient storage by folding so as to occupies a small space. CONSTITUTION: A module(10) has a plurality of keys and is multi-divided for making a shortening of a length possible. A key matrix(20) is received on the module(10) and creates signals with respect to each key. A slider(30) is mounted capable of being entered from a divided one side of the module(10) to other adjacent side thereof. A connection plate(40), which is made of a soft material, is joined to a divided portion of the module(10) for an easy folding and spreading process. A signal processing unit(50) decodes the signal of the key matrix(20) into a predetermined digital signal.
