Abstract: An optical rotary encoder includes four photosensor elements aligned in a square fashion. A first pair of diagonally aligned photosensor elements develop output signals of inverse phase with respect to each other as a slit plate rotates. The thus obtained output signals are applied to a comparator to obtain a first control signal. A second pair of diagonally aligned photosensor elements develop output signals of inverse phase with respect to each other as the slit plate rotates. The output signals from the second pair of photosensor elements are applied to another comparator to obtain a second control signal.

Abstract: An optical rotary encoder includes a slit plate having a plurality of circumferentially aligned slits of a pitch P, a light emitting diode, and a light responsive section. The light responsive section includes four photodiodes formed on a single substrate. The four photodiodes are aligned in the tangential direction of the slit plate with the interval corresponding to 1/4 P. Output signals derived from each of the four photodiodes are introduced into a detection circuit for determining the angular position and velocity of a rotating shaft to which the slit plate is secured.

Abstract: PURPOSE: To provide an input device for the computer which has no mechanical operation part and can input three-dimensional position information with superior durability and reliability. CONSTITUTION: An optical sensor 33 having a linear PSD 32 and a two-dimensional PSD 31 arranged across an LED 30 is put in a case 41 and fixed to a keyboard 37. Above an optical sensor 33, a stick type operation part 34 having a reflecting plate 45 at its lower end is supported on the top surface of a keyboard 37 in a free slanting and a free upward/downward movable state across a rubber-made support part 51 having elasticity. Light emitted by an LED 30 is reflected by the reflecting plate 45 to be projected on PSDs 31 and 32 and the tilt state and vertical position of the operation part 34 are detected from their output currents and outputted as three-dimensional information to a computer main body to move the cursor of a display device of a computer main body in three dimensions.

Abstract: PURPOSE: To easily check operation by inputting a two-dimensional (2D) or three-dimensional(3D) position information to a computer or the like by an input part and displaying applied operating direction and manipulated variable on a display part by the input part. CONSTITUTION: A cursor 51 on a display device 50 for a computer or the like is moved by operating an input part 20 in the 2D or 3D direction and an operating direction and a manipulated variable are two-dimensionally displayed on a display part 21 correspondingly to the movement of the cursor 51. These data are displayed in the 3D direction by the intensity of a color tone or a change of colors. Since an operation state can be visually and instantaneously recognized, operation can easily be checked. When an optional position on the display part 21 is selected by the input part 20 in executing mutual communication between the input part 20 and the display part 21, a panel-like multi- selection switch function can be obtained.
