Abstract: The cell transfer device includes a head group including a plurality of heads to which tips are attached and which move along a first direction; a head unit in which the head group is installed and which moves in a second direction and in a third direction; and a plurality of drive motors which are mounted on the head unit and which generate driving force to cause the head to move along the first direction. The plurality of drive motors are separately arranged on one side and the other side in the third direction with the head group provided therebetween. The head group includes a first head and a second head. The first head is driven by the drive motor arranged on the one side in the third direction, and the second head is driven by the drive motor arranged on the other side in the third direction.

Abstract: An imaging system includes an imaging device configured to image an imaging subject on an imaging optical axis, and a calculation unit configured to acquire data relating to a position and/or a size of the imaging subject based on image information acquired by the imaging device through the imaging. The calculation unit acquires change information relating to condition change in the imaging and/or change in the imaging subject on the image. The change is caused by interposition of a light transmitting member when the light transmitting member is interposed on the imaging optical axis during the imaging, and the calculation unit corrects the data based on the change information.

Abstract: A pretreatment method for cell transfer is a pretreatment method to be performed for transferring a required cell to a predetermined transfer destination by picking the cell, from a mass containing a plurality of cells of different sizes, using a cell transfer device including cell picking means. The pretreatment method includes a classification step of classifying the required cell, from among the plurality of cells contained in the mass, into at least two groups according to a size of the cell; and a supply step of supplying the classified cells, in a state of being individually classified, to a position where picking can be conducted by the picking means.

Abstract: A head device for mounting a dispensing tip includes a piston member, a first shaft member to move the piston member in an up-down direction, a tubular rod including a tubular space having a cylinder space in which the piston member is housed to move in the up-down direction and including a tip mounting portion into which a base end portion of the dispensing tip is fitted, a first frame equipped with the first shaft member and the tubular rod, a second shaft member engaging with the first frame to move the first frame, a second frame equipped with the second shaft member and including a guide portion configured to guide movement of the tubular rod in the up-down direction in association with the movement of the first frame in the up-down direction, and a shaft controller configured to control operation of the first and second shaft members.

Abstract: An object moving device includes: a first drive mechanism configured to move a head unit in a first direction and in a second direction; a second drive mechanism configured to move an illumination unit in the first direction; and a third drive mechanism configured to move a camera unit in the first direction. A control unit controls the first drive mechanism to move the head unit on a first path. The control unit controls the second and third drive mechanisms to move the illumination unit and the camera unit on the first path between the first container and the second container. When the head unit and the illumination unit interfere with each other on the first path, the control unit implements control such that the head unit moves in the second direction and the head units moves in the first direction on a second path parallel to the first path.

Abstract: A cylinder tip mounting head includes: a shaft member; a first cylindrical rod having a cylindrical space, which is mounted to a lower end of the shaft member, which is configured to move in the up-down direction integrally with the shaft member; a stationary second cylindrical rod, which has a housing space for housing the first cylindrical rod so that the first cylindrical rod is movable in the up-down direction, the stationary second cylindrical rod including a syringe mounting portion; and a discharge rod housed in the cylindrical space in the first cylindrical rod, the discharge rod including a plunger mounting portion. The discharge rod is configured to coordinate with the movement of the shaft member in the up-down direction so that the plunger mounted to the discharge rod reciprocates in the tubular passage in the syringe to suck the object into the tubular passage and discharge the sucked object.
