Abstract

PURPOSE: To decrease the number of the input keys for the computer featuring the function to perform the operation of the trigonometric function by providing the means which decides the combinations among the leg. base, height, angles and other factors and then carrying out the operation based on the combinations.
CONSTITUTION: Numerical input device IU incorporates the function which detects the operation for numberical keys 0W9 and then memorizes the coded signals corresponding to keys 0W9. At the same time, order execution signal generators I1WI4 are provided to generate the signals corresponding to operation for leg key SK, base key BK, height key HK and angle key RK each. By the signals generated through these signal generators, the numerical information memorized in device IU is transferred to memories S1WS4 via AND gates G1WG4. Furthermore, the ROM is added to memorize the combination information among signals of generators I1WI4, along with the CPU including arithmetic part ALU and register ACC. Then the combinations are derided among I1WI4 via AND gates AG1WAGN, thus carrying out the operation of the trigonometric function.
