PURPOSE:To make hearing easy eliminating voice reproduction of a code signal from a speaker by making muting of the speaker by a start signal recorded at the head or before the head of the code signal. CONSTITUTION:Direction and instruction, numerical value of solution from the keyboard of an input terminal equipment, and a code signal a0 read from a magnetic head 8 and a card detection signal from a card detection switch 9 are given to a microcomputer 12 through an input/output controlling section 11. Specified processes such as judging of correct answer and incorrect answer, counting of the number of correct answers etc. are made by the microcomputer 12, and a memory section 13 for storing is provided in the microcomputer. Being based on specified processes in the microprocessor 12, specified display by a five digits seven segments display unit 14, putting on and off of a pair of correction lamps 15a, 15b, and control of muting for voice reproduction from a speaker 16 of an audio signal b0 read by the magnetic head 8 are made through the input/ output controlling section 11. |
