Abstract
A saving box is disclosed, which senses an amount of a coin in accordance with the size of the coin thrown in the saving box and automatically releases a locking unit in accordance with the sensed amount. To this end, an electrical contact node is installed in a rotating lever, and a plurality of another contact nodes are installed to electrically connect with the contact node of the lever in accordance with a rotational angle. Thus, the number of coins thrown in the saving box can be checked by a simple mechanism. At the same time, the amount of the coins can be sensed by load of the coins after the coins pass through the lever.

A saving box which senses an amount of coins inserted in a coin slot and accumulatively calculates the amount of the coins so that a controller automatically opens a door to drawn out the coins if the accumulated amount reaches a target amount, the saving box comprising:
- a guide means connected to the coin slot to guide the coins descending by tare;
- a lever guided by the above said guide means and rotated by load of the descending coins, having a first terminal electrically connected to the controller;
- a plurality of second terminals electrically connected to the first terminal of the lever as the lever rotates and each electrically connected to the controller;
- and
- an elastic means providing restoring force to allow the lever to return to its original position after the lever rotates.
