Abstract
An optical reader is suitable for reading 2-dimensional indicia. The optical reading device, that may include a bar code reader, comprises a guide whose length along the optical reader optical axis is such that when that guide contacts the part or equipment surrounding the indicia to be read, that indicia is within the optical reader depth of field. The reader comprises a housing having therein a source of illumination and optics for producing a diverging beam for illuminating indica. A spacing element transparent guide is removably attached to the housing, and does not block indicia. The line of contact of the guide with the data carrier is substantially fully visible to the operator, who can thus confirm that the guide is in proper operating position relative to the indica prior to initiating a reading operation. A reading operation can be initiated by pressing on the guide to actuate a switch, or on a manual trigger.
