Abstract: An optical reading device authenticates an identification medium with cholesteric liquid crystal layer, having a structure in which no movable parts are necessary for switching circular circularly polarized light filter. The optical reading device reads an image from an identification medium having a cholesteric liquid crystal layer having a hologram processed, and an ink printed pattern layer in this order, and the device includes a light emitting part in which a right circularly polarized light filter is arranged in front of an LED, a light emitting part in which a right circularly polarized light filter is arranged in front of an LED, and a controlling part which switches light emission between the light emitting parts.

Abstract: An identification medium can be used in an opening label, clearly show signs of it having been opened, and also have a superior authenticity-confirming function. The identification medium has a structure including, in the following order as seen from the side of observation: an optical function layer that generates a color shift, a separation layer that is partially formed, a printed layer, and an adhesive layer, in which when an adhesive strength between the adhesive layer and an adherend is set to be Xa, an adhesive strength between the adhesive layer and the printed layer is set to be Xb, and an adhesive strength at a portion in which the separation layer is laminated between the optical function layer and the printed layer is set to be Xc, the adhesive strength of each part is set to satisfy Xa>Xb>Xc or Xb>Xa>Xc.

Abstract: An identification medium can be affixed to cloth or leather products by sewing. A cholesteric liquid crystal layer on which an embossed surface for forming a hologram is formed, is sandwiched between a first supporting member and a second supporting member. A mounting region that can be affixed to clothing, etc., by sewing, is formed.
