IPC: G02B17/08
Filed: 1981-09-10
Abstract: PURPOSE:To obtain a reverse expand afocal illuminating optical system of mirror condensing type having an improved distribution in quantity of light and higher efficiency  by making the light from a light source condensed with a reflecting mirror having a  quadratic surface to parallel luminous fluxes by means of a condenser lens and passing the same through a circular conical refracting member. CONSTITUTION:In an afocal optical system wherein the vertexes of a circular conical  refracting member are made coincident at the optical axis of an illuminating optical  system behind a condenser lens, the inequalities (1), (2) are satisfied wherein the half of the vertical angle of said refracting member is defined as theta, refractive index n, central  thickness d, radius of vignetting of lens Ds, height of optical axis He, and the quantity  of shift DELTAh. The light of the light source provided on one focus O of an elliptical  mirror 1 is condensed onto the other focus O' and is converted to parallel luminous  fluxes by a condenser lens 2. The parallel luminous fluxes apart from the optical axis  are shifted near the optical axis by a circular conical prism 3. Thus the reverse expand focal illuminating optical system having an improved distribution in the quantity  of light and higher efficiency is obtained.

Filed: 1986-06-17
Abstract: PURPOSE:To decrease reading errors by providing a switch for switching power supply to a card reader independently of a reader and setting a switch actuator and the reader to that mutual position control is possible between them. CONSTITUTION:A switch 7 contains a microswitch and is fixed to a board 16 set in a housing 1. A card 4 is put into a guide groove 2 and an actuator 6 is pressed against the force of a spring 15.
