The input device which includes a reflection type optical sensor having light emitting means and light receiving means; an operation section disposed facing the optical sensor, the operation section being tilted when a load is applied thereto; and output means for detecting a tilt status of the operation section based on signals from the light receiving means and outputting detected results to a computer body as positional information.

Input device for a computer and the like and input processing method

An optoelectronic device for sensing an object without any contact, the optoelectronic device being adapted to be connected to a control device which is capable of sending an identification code to the optoelectronic device, the optoelectronic device includes an optoelectronic element (110, 111) for receiving an input signal and for converting the received signal into an electrical signal, an address memory (121) for storing a self identification code, a determining unit (126) connected to the address memory (121) for determining a coincidence between the self identification code stored in the address memory (121) and the identification code sent from the control device, and an activating unit (127) connected to the determining unit (126) for driving the optoelectronic element (110, 111) at a time when the self identification code coincides with the identification code.

Optoelectronic device, information apparatus and data transmission

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.

Optical rotary encoder

Disclosed is a photoelectric encoder for providing an electrical pulse signal corresponding to the rotational position and direction of a disk rotor. The encoder possesses a feedback means including a second light sensitive means and associated circuit for obtaining the stabilized output signal thereof in spite of the fluctuation of the power source voltage and/or ambient temperature or adhesion of extraneous substances to light emitting and/or sensing elements and others.
