INFORMATION PROCESSOR

PROBLEM TO BE SOLVED: To provide an information processor flexible in layout, arrangement, and extendability when plural unit housings are connected to each other and are installed in a room. SOLUTION: In each housing 1 and 1', the door 2 is attached to the front surface and rear surface of a frame whose horizontal cross sections are formed into almost square rectangular parallelopipeds by the frame, and side plates 3 are attached to the side surface not being a connection part side. The door 2 is constituted so that two sheets of door are attached to the both-side parts of the housing by a hinge, etc., and is formed into a double door so that a decorative piece 5 may come to butting parts. In each door, the one sheet is formed into waveform shape recessed from the end part of the door in the inside direction of the housing at the center part in a width direction by a thin plate. On the side of the decorative piece 5, a recessed part which can be touched from the outside is provided. The door is provided with a slide part 7 and the operation panel 6 can be operated. The side plate 3 is divided into two in the same way as the door 2, is formed into a waveform shape and is fixed to the frame of the housing by holding the decorative piece 5.
