Abstract
Abstract A sound-producing tape is wound on a reel having a spring-driven rewind. As the tape is pulled from the reel past a sound reproducer and a pivoted finger, the finger is pivoted due to its frictional engagement with the tape allowing the tape to inoperatively pass the sound reproducer. Upon release, the tape is automatically rewound onto the reel and is brought into operative association with the sound reproducer by the pivoted finger so that sounds are reproduced only during the rewinding operation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
164 words
In a sound-reproducing apparatus suitable for use in toys including: drum means; elongated sound track carrier means attached to said drum means; spring means connected to said drum means for rotating said drum means in a direction to normally wind said sound track carrier means onto said drum means; governor means for controlling the speed of rotation of said drum means; said sound track carrier means having a free end adapted to be pulled to unwind said sound track carrier means from said drum means while adding energy to said spring means; and sound-reproducing means for reproducing sounds recorded on said sound track carrier means, the improvement comprising: pivoted means frictionally engaging said carrier means for holding said carrier means against said sound-reproducing means only during winding of said sound track carrier means onto said drum means by said spring means and being responsive to movement of said carrier means when being unwound from said drum means to swing away from said reproducing means.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
56 words
An improvement as stated in claim 1 wherein said sound-reproducing means includes a speaker cone having a wedged shaped apex, wherein said sound track carrier means has ridges engageable with said apex and wherein said pivoted means comprises a finger means swingably mounted adjacent said apex for forcing said sound track carrier means into engagement therewith.
Claim 4
Dependent Claim
62 words
An improvement as stated in claim 1 wherein said sound-reproducing means includes a speaker cone having an aperture provided in its apex, wherein said sound track carrier means has ridges engageable with an edge of said aperture and wherein said pivoted means comprises finger means swingably mounted in said aperture for forcing said sound track carrier means into engagement with said edge.
