Abstract
PURPOSE:To obtain a compact electronic calculator by producing the input information such as the numeric characters, after detection of both photodetecting and non-photodetecting parts. CONSTITUTION:The photoreceiving electromotive parts 11-13 are provided on an electronic calculator together with the electromotive power detecting parts 21-23, a calculation part 30 and a display device 40. The upper surface side of the calculator includes a photodetecting part 100 having the photodetecting holes and a display part 200. When an operator closes one of those holes by his/her finger, the corresponding one of parts 11-13 has no actuation. At the same time, the corresponding one among parts 21-23 stops the transmission of the start signal to the part 30. Thus the part 30 performs an arithmetic operation by defining a fact that no electromotive signal exists as the input information and displays the arithmetic result on the device 40. The operator recognizes the arithmetic result via the part 200. In such a way, the input information such as the numeric characters, are produced with detection of both photodetecting and non-photodetecting parts. Then a compact electronic calculator is obtained.
