Abstract
An expression-varying device is disclosed. The device includes a supporting member that supports two eyeball bodies so that the eyeball bodies are free to pivot. The device also includes a connecting member that connects the two eyeball bodies, and that supports the eyeball bodies so that the eyeball bodies can pivot in synchronization in a side to side or left to right direction. The device includes a swinging mechanism that causes the connecting member to swing upward and downward and to the left and right. The swinging mechanism includes a disk in which a recessed groove is formed in a side surface of the disk and runs in a circumferential direction. The depth of the groove and distance of the groove from the center of the disk vary according to relative positions on the disk. The swinging mechanism includes a motor that causes the disk to rotate. An engaging shaft which engages with the recessed groove of the disk is formed on and protrudes from and to the side of the arm member. The arm member is driven by a driving member so that the tip end of the engaging shaft constantly contacts the bottom part of the recessed groove. The tip end of the arm member is caused to swing upward and downward and to the left and right in linkage with the recessed groove of the disk. Accordingly, the connecting member is caused to swing upward and downward and to the left and right, thus causing the two eyeball bodies to pivot so that various expressions are displayed.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
