Abstract: A digital camera comprises an interchangeable lens unit and a camera body. The interchangeable lens unit is provided to form an optical image of a subject. A flash memory is configured to hold a correction coefficient table used to electrically correct distortion produced by the optical system. The camera body has a CCD image sensor, a correction coefficient acquisition part, an operation part, and a correction processor. The correction coefficient acquisition part is configured to acquire the correction coefficient table held in the flash memory. The operation part is configured to produce correction data by performing an interpolation operation or an extrapolation operation on the information obtained from the correction coefficient table. The correction processor is configured to correct distortion in the image data on the basis of information produced by the operation part.

Abstract: A lens position calculator is provided that determines a phase of a driving signal as a reference position of an imaging lens when an output value of a position detection sensor reaches a threshold value. The lens position calculator determines a position obtained by performing addition or subtraction on the reference position read out from a reference position storage as a judgment position, detects an output value of the position detection sensor at a timing in synchronization with the driving signal that drives a driver and at the judgment position, and judges whether the output value of the position detection sensor at the judgment position reaches the threshold value or not, so as to determine the reference position again.

Abstract: A camera system that can maintain a good focus state regardless of the speed of zooming during variable proportion zooming is provided. The camera system has a control portion that, based on information on the speed of the change in the focal length, determines whether to control a focus lens drive portion in either a first control mode or a second control mode. If it determines that control is to be performed in the first control mode, then the control portion controls the focus lens drive portion so that it drives a focus lens in the direction that brings a predetermined captured object into focus based on estimated values for auto focusing that have been calculated from the image data at various positions by controlling the focus lens drive portion so that the captured object distance is moved forward and backward in the optical axis direction.

Abstract: An image forming apparatus includes an intermediate transfer belt having a coated layer as a surface layer that carries an developer image on the surface layer, a light-emitting member that emits light rays having a predetermined wavelength toward the surface layer of the intermediate transfer belt, and a sensing member that senses the light rays reflected from the intermediate transfer belt. The intermediate transfer belt includes a metal layer whose light reflection coefficient is larger than that of the coated layer and an intermediate layer positioned between the coated layer and the metal layer, and the intermediate layer that restrains the different light rays having a wavelength other than the predetermined wavelength from reflecting from the intermediate transfer belt.

Abstract: A liquid ejecting apparatus includes two liquid discharge heads and a suction unit. Each of the two liquid discharge heads has a nozzle face on which at least one nozzle opening for discharging liquid is formed. The two liquid discharge heads are located so that the nozzle faces of the two liquid discharge heads face each other. The suction unit is placed between the nozzle faces of the two liquid discharge heads. The suction unit draws liquid on the nozzle faces between which the suction unit is placed.

Abstract: A liquid ejecting apparatus includes two liquid discharge heads, a wiper unit, and an actuating mechanism. Each of the two liquid discharge heads has a nozzle face on which at least one nozzle opening for discharging liquid is formed. The two liquid discharge heads are located so that the nozzle faces of the two liquid discharge heads face each other. The wiper unit is pressed against each of the nozzle faces of the two liquid discharge heads at a position at which the wiper unit is placed between the nozzle faces of the two liquid discharge heads. The actuating mechanism reciprocally moves the wiper unit relatively along the nozzle faces of the two liquid discharge heads.

Abstract: A liquid ejecting apparatus includes nozzles that eject a liquid, and n number of nozzle groups. Dot rows along a transport direction formed within the nozzle groups include alternating dense areas and sparse areas. A length in a direction of the dot rows from one of the dense areas to another of the dense areas is a predetermined length. A length in the dot row direction from a particular one of the dense areas of one of the dot rows formed with a certain one of the nozzle groups among n number of nozzle groups to a particular one of the dense areas of one of the dot rows formed with another of the nozzle groups, is equal to a length resulting from adding a non-negative integral multiple of the predetermined length to a length obtained by dividing the predetermined length by n.

Abstract: There is prepared at least one flame retardant sheet member in which a flame retardant layer comprised of a flame retardant agent having extinguishability is sandwiched between resinous layers. One end face of the at least one sheet member and another end face of the at least one sheet member are opposed to each other while forming a clearance therebetween. A first welding member having a first width larger than a width of the clearance is placed on one face of the sheet member. The first welding member is welded with the end faces of the at least one sheet member such that the first welding member is melted and pushed into the clearance while the flame retardant agent situated in the vicinity of the end faces is pushed out from the clearance, thereby forming a joint portion. A second welding member having a second width larger than the first width is placed on the joint portion. The second welding member is welded with the at least one sheet member.
