Expression-varying device
First Claim
1. An expression-varying device for a toy comprising:
- a first facial element; and
a drive coupled to said facial element, said drive including a shaft, a disk mounted on said shaft, and an arm member engaged with said disk and coupled to said facial element, rotation of said shaft rotating said disk, which in turn moves said arm member, which imparts movement in a first direction and in a second direction substantially perpendicular to said first direction to said first facial element.

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.

11. A method of producing multiple expressions in a toy comprising:
-
moving a first facial element in a first direction, said first facial element being an eyeball body;
moving said first facial element in a second direction, the second direction being substantially perpendicular to the first direction; and
moving a second facial element substantially simultaneously with said moving said first facial element in a second direction, said second facial element being an eyebrow body. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 30, 31)

20. An expression-varying device for a toy comprising:
-
a supporting member pivotally supporting two eyeball bodies for rotation about two substantially perpendicular axes;
a connecting member connecting said two eyeball bodies, said connecting member connecting said eyeball bodies so that said eyeball bodies can pivot simultaneously; and
a drive connected to said connecting member and adapted to cause said two eyeball bodies to move in a first direction and in a second direction substantially perpendicular to said first direction to produce various facial expressions for the toy. - View Dependent Claims (21, 22, 27, 28, 29)

23. An expression-varying device for a toy comprising:
-
a first facial element; and
a drive coupled to said facial element, said drive including a shaft, a disk mounted on said shaft, and an arm member engaged with said disk and coupled to said facial element, rotation of said shaft rotating said disk, which in turn moves said arm member, which imparts movement in a first direction and in a second direction substantially perpendicular to said first direction to said first facial element, said disk including a center and a groove extending about said center, the distance between said groove and said center varying along said groove, and said groove varying in depth along said groove.
