a first tray configured to hold an ink container filled with ink, the first tray comprising a cut-out engagement portion formed in a side wall of the first tray;
a support member configured to support the tray, the support member comprising a base with a pair of arm portions, wherein with a center of the base being a rotational axis, the pair of arm portions are formed to have a two-fold rotational symmetry, wherein the support member supports the support tray as the arm portions of the support member resiliently deflect outwardly from a center axis of the support member to be received within and overlap the cut-out engagement portion;
a rotary member configured to support the support member; and
a pedestal configured to rotatably support the rotary member and weighted to hold a posture of the stirring device when the first tray is rotated,
wherein the first tray and the support member are engaged with each other by engagement portions provided on the support member engaging with the cut-out engagement portion, the engagement portions provided on the support member including convex portions having a substantially triangular cross section that project from an inward side of the pair of arm portions.
