Abstract: An information code reader is provided to read an information code, such as a QR code (registered trademark). In this reader, a marker light irradiating unit is provided in a position farther away from a reading opening than a reflective mirror is, and disposed such that an optical axis of a marker light is parallel to an optical axis that is a center of an imaging area of a light receiving sensor and the marker light is close to (or in proximity to) an upper edge (outer edge) of the reflective mirror.

Abstract: In an optical information reader which optically reads an information code, a first polarizing unit arranged on the light-exit side of a lighting unit is configured to polarize illumination light therefrom in a predetermined polarization direction. In addition, a second polarizing unit arranged on the light-reception side of a light receiving sensor is configured as a switchable polarization unit, in which the switchable polarization unit is capable of performing a switchover between a polarized state in which light reflected from the information code is polarized in a direction different from the predetermined polarization direction and a passing state where the reflected light passes therethrough without being polarized.

Abstract: A configuration that enables easy implementation of wiping disinfection for a gripping handle for which an operating means is provided. The gripping handle, which is grasped by an operator, is formed as part of the lower case including part of the housing. The gripping handle is provided with an operating surface portion that the operator touches when initiating the reading process. There is a site on the inner side of the gripping handle, wherein the site is opposed to the operating surface portion. At this site on the inner surface side, a detector is provided to detect the state in which the operating surface portion is touched.
