摘要： A ROM unit mounted to a bottle has a plurality of terminal plates on the front end surface of the ROM unit. The ROM unit is movable in a direction orthogonal to a bottle axis Ax, and can be positioned at a retreat position where an interference with a contamination preventing eaves is avoided, and a contact position projected more front than the retreat position. The terminal plates can be electrically contacted with reservoir terminals when positioning at the contact position.

摘要： An analysis and observation device includes: an electromagnetic wave emitter that emits a primary electromagnetic wave; a reflective object lens having a primary mirror provided with a primary reflection surface reflecting a secondary electromagnetic wave and a secondary mirror provided with a secondary reflection surface receiving and further reflecting the secondary electromagnetic wave; first and second detectors that receive the secondary electromagnetic wave and generate an intensity distribution spectrum; and a controller that performs component analysis of a sample based on the intensity distribution spectrum. A transmissive region through which the primary electromagnetic wave is transmitted is provided at a center of the secondary mirror. The transmissive region transmits the primary electromagnetic wave, which has been emitted from the electromagnetic wave emitter and passed through an opening of the primary mirror, thereby emitting the primary electromagnetic wave along an analysis optical axis of the reflective object lens.

摘要： Even if a size of a read image is large, a code search process can be speeded up to enable immediate output of a decoding result. Each time a predetermined number of lines of image data is taken, a pre-processing circuit executes pre-processing on the image data and calculates a characteristic amount indicating the likelihood of the code for each area in the image data. A processor determines a code candidate area based on the acquired characteristic amount and executes a decoding process of the determined area to generate a decoding result.

摘要： A handheld optical information reading device is provided which comprises a housing, a grip arranged on the housing, an image capture device, an illuminator, an illumination controller, an imaging controller, an image processor, and a reader. The image capture device captures an image including a symbol. The illuminator includes lighting devices around the periphery of an optical axis of the image capture device. The illumination controller controls the illuminator to selectively successively light up the lighting devices based on a predetermined order whereby irradiating a symbol with light in different illumination directions with respect to the optical axis. The imaging controller controls the image capture device to capture images of the symbol every when the lighting devices are selectively successively lighted up. The image processor creates an outline image of the symbol based on the captured images. The reader reads the symbol based on the created outline image.

摘要： A sufficient decoding processing time for each image acquired by performing high-speed imaging is secured to obtain a stable reading result, thereby enabling immediate output of the obtained reading result. A processing unit has a first core and a plurality of second cores. The first core instructs the second cores, presumed to be capable of immediately executing the decoding process or executing the decoding process next to a decoding process being currently executed, to execute the decoding process. The second cores are configured to be capable of simultaneously executing the decoding process on read images instructed by the first core at different timings.
