A mobile communication device includes a first plate, and a second plate provided with guide rails on respective edges thereof and slidably coupled to the first plate. The number of inputoutput wires connected to IO terminals of the semiconductor integrated circuit is reduced so as to simplify wiring patterns of the IO wires, whereby degrees of freedom in arranging the IO wiring patterns are enhanced. The user selected position is determined by the processor from signals received from the stylus, or flexible layer, each in relation to a similar excitation of different pairs of the contact points under control of the processor. In the beam path, there is a first dispersive element so that the fluorescent light emitted by the specimen surface can strike the selection element spectrally split.
