Abstract

PURPOSE: To provide an apparatus for converting pressute into electric signal, in which fluid pressure is converted into mechanical displacement by means of diaphragm or other, and image on light-sensitive surface of a light receiving element is shifted with the above displacement, thus enabling to convert the mechanical desplacement into electric signal, whereby sensitivity of the apparatus can be improved.
