Abstract

A stirring device includes a tray configured to hold an ink container filled with ink, a support member configured to support the tray, a rotary member configured to support the support member, and a pedestal configured to rotatably support the rotary member, in which the tray and the support member are engaged with each other by engagement portions provided on the tray and the support member (engagement cut-out portion, engagement convex portion).

First claim

What is claimed is:

1. A stirring device comprising:
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.

2. The stirring device according to claim 1 , wherein a second tray is stacked and engaged with the support member.

3. The stirring device according to claim 1 , wherein each arm portion comprises one of the engagement portions.

4. The stirring device according to claim 1 , wherein the support member and the rotary member are integrally formed.

5. A stirring device comprising:
a plurality of trays each configured to hold an ink container filled with ink;
a set member configured to set the plurality of the trays;
a support member configured to support the set member, 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 set member 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 cut-out portions of the set member;
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 set member and the support member are engaged with each other by engagement portions provided on the support member engaging the cut-out portions of the set member, 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.

6. The stirring device according to claim 5 , wherein each arm portion comprises one of the engagement portions.

7. The stirring device according to claim 5 , wherein a mounting portion configured to mount at least one of the plurality of trays is formed in the set member.

8. The stirring device according to claim 7 , wherein the set member includes a slip-off preventing portion configured to prevent one of the plurality of trays from slipping off.
