Filed: 1990-05-14
Abstract: PURPOSE:To prevent the generation of a noise in a cordless telephone set, etc., in the course of speech by selecting successively a switch group from the direction being different from the read-out direction and detecting the output information, when the read-out output information is different from the output information at an initial time. CONSTITUTION:Output information of a switch group is read out of the direction of one of the direction and the column direction of the switch group, and in the case the read-out output information is different from output information at an initial time, the switch group is selected successively from the direction being different from the read-out direction and this output information is read out. For instance, in the case the output information of the switch group in the direction, that is, input data from input ports a1 - a4 are read out and all of them are not [H] level data, the switch group in the column direction, that is, output ports b1 - b5 are selected successively and the output information of the switch group in the row direction is read out and detected. In such a way, since the key detection is executed only at the time when keys 2, 3 are depressed, a noise in the course of speech of a telephone set caused by a selecting operation of the switch group can be eliminated.
