Change device of multiple manipulation aspects

摘要

(57) Abstract Objective Multiple key surfaces either one of 11 and 12 operational surface sideWhether it is and securely distinguishing, automatic, ki of on the one hand aspect- Just 17 designates that those which are made operation possible are obtained as purposeru. Constitution 1st and 2nd it provides in the inside and outside of key manipulation itself 10The key surface 1st the respective luminous intensity of 11 and 12 is detected,Light absorbent component 20 for 2nd key surface, 21 and mutual photometricThe comparator in output of 35 which it compares distinguishes and this comparator 35The ri only the key surface which corresponds the control means which are controlled in operating state toolPreparation it does, it provides in the one hand the key surface luminous intensity of the light absorbent component which, another sideWhen being larger than luminous intensity of the light absorbent component which is provided on the key surface, on the one handAs the key surface is put in operation (stand-by) state, other thingsTo put the key surface of one in bad harvest dynamic (sleeping) state, when converseAs the coming and the other key surface are put in operating state, on the one hand ki- With the change device of the multiple manipulation aspects which designate the surface as the bad harvest moving state aru.
