摘要 PROBLEM TO BE SOLVED: To provide an easy-to-assemble keyboard device with reduced manufacturing cost due to reduced cost of a chassis. SOLUTION: This device 1 is equipped with chassis 2 which are arranged in the right-left direction, keys 3 which are provided rotatably to the chassis 2 and arranged in the right-left direction, and a connecting member 4 which mutually connects the plural segments of the chassis. The chassis for one keyboard device are divided into the plural segments which can be manufactured separately, so the chassis are each made smaller in size than that in a conventional case wherein one chassis is manufactured for each keyboard device. In this case, at least some of the chassis are composed preferably of one kind of chassis which have similar sizes and shapes.
