1. A cell transfer device comprising:
a head group including a plurality of heads to which tips are attached and force driven for suctioning and discharging cells and which are configured to move along a first direction;
a head unit includes the head group including the plurality of heads, and a head main body in which the head group is installed, and the head unit is configured to move in a second direction orthogonal to the first direction and in a third direction orthogonal to both the first direction and the second direction,
wherein the first direction comprises an up-down direction, the second direction comprises a right-left direction, and the third direction comprises a front-rear-direction; and
a plurality of drive motors which are mounted on the head unit so as to each correspond to each of the heads and which are configured to generate driving force to cause the head to move along the first direction,
wherein the plurality of drive motors are separately arranged on one side and the other side of the head unit in the third direction with the head group provided therebetween in a plan view from the first direction,
the head group includes at least a first head and a second head adjacent to the first head in the second direction, the first head being driven by the drive motor arranged on the one side in the third direction, and the second head being driven by the drive motor arranged on the other side in the third direction,
wherein the plurality of heads provided in the head group are linearly aligned in the second direction and divided into heads belonging to a first group and heads belonging to a second group,
the heads of the first group including the first head and being driven by each of the drive motors arranged on the one side in the third direction, and
the heads of the second group including the second head and being driven by each of the drive motors arranged on the other side in the third direction.
