Patent number: 11927032Abstract: An automated analysis device is provided with a casing accommodating an analysis device. A cover is axially supported with freedom to pivot, between a closed position and an upwardly-open open position, about a support shaft provided at one side of the casing. A closing device is capable of inhibiting opening of the cover in the closed position, and is provided with a projecting portion that protrudes from a front surface of the cover toward the rear, a lock lever which is axially supported with freedom to pivot about a pivoting support shaft, and which pivots from the work surface in a direction approaching the projecting portion to engage with the projection portion, thereby inhibiting opening of the cover. A safety cover can thus be locked securely.Type: GrantFiled: February 13, 2019Date of Patent: March 12, 2024Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Taichiro Yamashita, Takenori Okusa, Susumu Sakairi

Patent number: 11913966Abstract: When an automatic analysis apparatus has a mechanism that performs an operation of an arcuate trajectory to access a plurality of positions arranged on a straight line, an arc and a straight line cannot coincide with each other. Thus position adjustment is required to minimize the deviation between the arc and the straight line. An automatic analysis apparatus according to the invention includes a reagent disk which accommodates a plurality of reagent bottles in each of which a plurality of suction ports are arranged along a center line, and which rotates around a central axis to transport a reagent bottle to a desired position; and a reagent dispensing mechanism which rotates around a rotation axis to suck a reagent from the reagent bottle at a predetermined suction position on the reagent disk, in which the reagent disk is provided with, at least one mounting position of the reagent bottle on the reagent disk, first and second marks sandwiching the mounting position of the reagent bottle.Type: GrantFiled: January 21, 2019Date of Patent: February 27, 2024Assignee: Hitachi High-Tech CorporationInventors: Susumu Sakairi, Takenori Okusa

Publication number: 20210239727Abstract: A countersunk hole is added to a back surface of a dispensing chip mounting position of a sample dispensing chip installation table such that, when the dispensing chip is pulled up from the installation table, the amount of contact of a chip side surface is reduced and the chip is stably mounted. In addition, a posture control member during falling is added to a chip waste position, and the chip is caused to fall vertically and attachment of a sample to a waste route is suppressed. When a dispensing probe moves upward during dispensing chip separation, an upper end of the chip is moved upward up to a position in contact with a base and stopped and then is moved upward again. Thus, the posture of the chip during separation is stable. Further, plural positions for separating the chip are provided such that the position changes depending on waste timing.Type: ApplicationFiled: March 20, 2019Publication date: August 5, 2021Inventors: Susumu SAKAIRI, Takenori OKUSA, Takahiro KUMAGAI

Publication number: 20210063422Abstract: A driving mechanism for moving a vessel having a disposal box placed thereon in a front-rear direction the same as an opening/closing direction of a drawer is provided lower than a bottom surface of the vessel. A first rail extended in a movement direction of an operating unit, a second rail extended in a movement direction of the vessel provided in the drawer, and toothed pulleys for rotating a toothed belt within a horizontal plane are arranged. The first rail, the second rail, and the toothed belt are placed side by side without overlapping with each other in a vertical direction. As a result, the operation of taking out the disposal box in which used sample dispensing tips or reaction vessels are accumulated is simple.Type: ApplicationFiled: August 22, 2018Publication date: March 4, 2021Inventors: Taichiro YAMASHITA, Takenori OKUSA, Susumu SAKAIRI
