PURPOSE:To improve the operational efficiency to make input easy and sure, by rotating the rotary ring, which generates the rotation signal, by interlocking a switch to input the information. CONSTITUTION:When stem 2 is operated, rotary ring 5 is rotated, and rotation signal generation switch S1 and rotation direction detection switch S2 which are provided in positions different by the 1/4 period by grooves 10... on the reverse face and are formed by levers 11 and 12 and contact springs 13 and 14 respectively are opened and closed to generate rotation pulse (b) and rotation direction detection pulse (c) different by the 1/4 period. This pulse (b) is counted by counter 15 where up and down counting is controlled by pulse (c), and the count value corresponds to the number and so on of ring 5, which is selected and put upon the select mark, and is input to memory 16 and so on according to the operation of set switch 4. By this constitution, the input operational efficiency is improved, and input becomes easy and sure. |
