Abstract: A particle analyzer (100) includes: a light source that emits excitation light (EL1) including light having a wavelength of 400 nm or less; a lens structure (41) that collects excitation light (EL1) at a predetermined position (51s) in a flow path (53); a detection unit (7) that detects light (FL) emitted from a particle as the particle (51) flowing through the predetermined position is excited by the excitation light (EL1); and a processing unit (120) that processes detection data acquired by the detection unit (7). The lens structure (41) includes a plurality of lenses (411) arranged along an optical axis of the excitation light (EL1); and a lens frame (412) holding the plurality of lenses (411). At least one (G12) of the plurality of lenses (411) is positioned in the lens frame (412) by abutting on a lens adjacent to the lens.

Abstract: Certain embodiments provide an image forming apparatus including a drum configured to include a drum surface which rotates around a shaft in a rotation direction; a blade configured to clean residual toner after a toner image on the drum surface is transferred to a transfer-receiving member; and a holding section configured to hold a lubricant arranged in the blade at the upstream side of the blade in the rotation direction and cover both ends in a longitudinal direction of the blade on the drum surface.

Abstract: In accordance with one embodiment, an image forming apparatus comprises a fixing device configured to include a heating roller heated by a heating section and a pressing roller for pressing the heating roller; and a cleaning sheet configured to be stretched between a first reel and a second reel and wound on at least one of the first reel and the second reel to clean the heating roller; wherein the cleaning sheet is separated from or contacted with the heating roller by a movable member.

Abstract: In accordance with one embodiment, an image forming apparatus comprises a photoconductive drum on which an electrostatic latent image is formed, a developing device configured to supply developing agent to the photoconductive drum, a transfer device configured to transfer the toner image formed on the photoconductive drum by the developing device to an image receiving medium, a rotatable loop-shaped transfer belt configured to convey the image receiving medium through a space between the transfer device and the photoconductive drum, and a peeling plate configured to be arranged on a conveyance path of the transfer belt and be applied with preset peeling electric charge to separate and discharge the image receiving medium from the photoconductive drum and the transfer belt after the transfer processing.

Abstract: On an adapter mounting portion 3a having a projecting cross section which is formed on a cap 3 of a small-sized memory card 1, a recessed portion of an adapter 2 side is fitted so that both parts are formed as an integral unit in a replaceable manner. Accordingly, the small-sized memory card 1 can maintain the dimensional compatibility with respect to existing memory cards whereby the small-sized memory card 1 can be used also in equipment which is designed to cope with the existing memory cards.

Abstract: A first ball circulating hole and a second ball circulating hole for connecting a circulator are bored midway at a screw groove formed on an inner circumference of a ball nut, an intermediate groove path between the first and second ball circulating holes becomes the range of a ball screw track for circulating balls, and other ranges become a first outer track and a second outer track which are not the ball screw track. By making the groove depth of the intermediate groove path deeper than the groove depth of a first groove path of the first outer track and the groove depth of a second groove path of the second outer track, steps are formed between the ball screw track and the two outer tracks. These steps prevent an outflow of the balls from the intermediate groove path to the respective groove paths of the outer tracks.
