Abstract: An optical sensor includes at least one interferometer having a pair of semi-transparent mirrors spaced apart and oppositely arranged, and at least one position of the pair of semi-transparent mirrors can be displaced, at least one collimating element overlapping the at least one interferometer, and at least one photoelectric conversion element having sensitivity in the visible and near infrared light bands and receiving light passing through the interferometer and the collimating element.

Abstract: According to an aspect, a detection apparatus includes: an optical sensor including a sensor base member and a plurality of photoelectric conversion elements that are provided on the sensor base member and each of which is configured to output a signal corresponding to light emitted to the photoelectric conversion element; and a lighting device including a plurality of first light-emitting elements configured to emit first light having a first maximum emission wavelength and a plurality of second light-emitting elements configured to emit second light having a second maximum emission wavelength. Each of the photoelectric conversion elements has responsivity in a wavelength region including a wavelength region of the first light and a wavelength region of the second light.

Abstract: The ink server includes at least one ink storage unit that stores ink to be supplied to a printer, a switching unit that switches whether to supply the ink stored in the at least one ink storage unit to the printer, a detection unit that detects a state of the ink stored in the at least one ink storage unit, a controller that controls the switching unit and the detection unit, and a power supply circuit that supplies a power supply voltage to the switching unit, the detection unit, and the controller.

Abstract: A printing apparatus including printheads arranged along a transport path of a printing medium and which are transported in a transporting direction. The printheads have a plurality of nozzles arranged in an arrangement which intersects the transporting direction. The apparatus also includes a printhead control unit configured to print an image on the printing medium by discharging ink from part of the plurality of nozzles on the basis of given image data, and a discharge inspection unit configured to detect any defectively discharging nozzles present in the plurality of nozzles, the printhead control unit specifying specific nozzles which discharge ink for printing the image, determining whether any discharge-defective nozzle is included in the specific nozzles or not, and starting printing of the image when it is determined that no discharge-defective nozzle is included in the specific nozzles.

Abstract: The present invention provides an instant photographic film pack that is loaded in an instant camera. The instant photographic film pack can be produced at low cost, has little environmental impact, and has excellent handling characteristics. The instant photographic film pack includes a case body which accommodates therein self-developing type film units, has one side thereof open, and has an exposure opening for providing each one of the self-developing type film units with exposure, an ejection slit for ejecting the self-developing type film units after exposure thereof, and a reference surface serving as a reference for location when loaded into the instant camera; a covering portion covering the open side of the case body; and a light-shielding cover covering the exposure opening. The case body and the covering portion are formed of cardboard and/or a cellulose-resin composite or the like.

Abstract: A method for producing a fluid trap for an instant film assemblage, which method can produce an environment-friendly trap easily and at low cost, is disclosed. A plate-shaped paper material having a uniform width and a uniform thickness is passed through a clearance formed between a pair of rollers. The plate-shaped paper material is compressed at width-directional opposite end portions thereof such that a thickness of the paper material gradually decreases from a central portion thereof toward opposite ends thereof, and at the same time, the paper material is cut along a longitudinal direction thereof to a predetermined width. Thereafter, the paper material is cut along the width direction thereof at predetermined intervals with respect to the longitudinal direction thereof, thereby producing the trap.
