Schematic "Kissing Doll Coin Bank" Toy, Circa 1970, Japan.
The toy arrived disassembled, the cables were not identified, the PCB has no additional identification. Search Google as: "Kising Doll Bank Coin", the one I have, has a heart that lights up.
my english is a work in progress.

The mechanism has 4 switch, 3 physical and one of "coin", the problem is the set-up and synchronization between the melody, its duration and the movement of the figures.
Is this a good question?
Your English is fine. Without photos we really have no idea of how to help. Trying to find schematics on a fifty year old toy will be next to impossible.
