摘要： 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 (22) is provided in a position farther away from a reading opening (13) than a reflective mirror (24) is, and disposed such that an optical axis (Lgm) of a marker light (Lm) is parallel to an optical axis (Lgr) that is a center of an imaging area of a light receiving sensor (23) and the marker light (Lm) is close to (or in proximity to) an upper edge (outer edge) of the reflective mirror (24).

摘要： [Object] There is provided a configuration that enables easy implementation of wiping disinfection for a gripping handle for which an operating means is provided.
[Solution] The gripping handle 31, which is grasped by an operator, is formed as part of the lower case 30 comprising part of the housing 11. The gripping handle 31 is provided with an operating surface portion 34 that the operator touches when initiating the reading process. There is a site on the inner side of the gripping handle 31, wherein the site is opposed to the operating surface portion 34. At this site on the inner surface side, a detector 45 is provided to detect the state in which the operating surface portion 34 is touched.

摘要： A first polarizing unit (41) arranged on the light-exit side of a lighting unit (31) is configured to polarize illumination light therefrom in a predetermined polarization direction. In addition, a second polarizing unit (42) arranged on the light-reception side of a light receiving sensor (32) 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 an information code (C) is polarized in a direction different from the predetermined polarization direction and a passing state where polarized reflected light passes therethrough without being polarized.
