Provided is a dimension measuring apparatus which measures dimensions of a measurement target object without the need of complicated operations by a user. According to dimension measuring apparatus (), laser () radiates laser beams to form at least two feature points on a measurement target object. Decoder () measures a distance from the measurement target object by using reflection light of at least two laser beams reflected on the measurement target object. Imaging sensor (A) captures an image of the measurement target object to which at least the two laser beams are radiated. Dimension measurement section () measures a length of the measurement target object on a line connecting the two feature points on the basis of the distance from the measurement target object, a position of the measurement target object in the image, and positions of the two feature points in the image.

Dimension measuring apparatus, information reading apparatus having measuring function, and dimension measuring method

In an optical information reading device configured to read a code symbol on a subject to be read by acquiring an image of the subject to be read with an image pickup portion and analyzing the image, a laser light source and an irradiation optical system is provided as an irradiator configured to irradiate the subject to be read to form a guide mark indicating an image pickup resolution of the image pickup portion. It is preferable that the irradiator is configured to emit a plurality of radially diffused light beams so as to form the guide mark at equal intervals on the subject to be read.

Optical information reading device

An image reading device includes an illumination system and a processor that causes the illumination system to produce illumination according to an illumination period having a continuous or substantially continuous, illumination sub-period and at least one pulsed, illumination sub-period. The illumination period allows the image reading device to determine a proper exposure for imaged indicia by sectioning a single frame into individual exposures.

Optical information reader and optical information reading method

An imaging device preferably for use in a 2-D CCD or CMOS sensor is disclosed. The illumination means uses a plurality of illumination sources, some of which are coupled to lenses in an offset manner to promote far field illumination, and some of which are not so coupled and are arranged to provide near field illumination.

Optimized illumination for an omniscanner

In an optical code detection system and method, infrared pulses are utilized to detect the presence of an object within the range of an optical imaging device, but the image of an infrared pulse reflected from the object is also analyzed to determine the distance between the object and the imaging device. An illumination pulse is then produced to illuminate the optical code on the object, and the characteristic of that pulse, such as duration, are controlled to provide appropriate exposure for an object at the detected distance.
