A portable electronic coin holder for a facilitated withdrawal of coins up to a desired amount is constituted by a rigid container (1), in which the coins (M>1...8<) are in rows set face down on the bottom of distinct loading and withdrawal channels (11) comprising a thrust organ (15) and elastic holding means to position the last coin of the row projecting from the open end (13) of the channel (11). The roof (9) of each channel (11) is constituted by a printed circuit board, to detect, by means of a scan by rows, the position of the thrust organ (15) and hence the humber of coins contained in the channel (11). On the roof (9) is present an electronic circuit with a microprocessor, whereto are connected, in addition to conductive tracks of each channel (11), a keypad, a liquid crystal display, and a series of light emitting diodes. |
