• the upper panel 10 can totally or partially lack slots since the various components such as keys, displays, acoustic signalling device, can be incorporated in a highly integrated pre-assembled element (not shown in the drawings).
• the microprocessor 24 is provided with at least a ROM in which the application program is stored, a RAM in which are stored the values of the variables necessary for the calculations and for the operation of the device in general, and with other resources such a process arithmetic unit (ALU), timers, counters, interrupts, necessary to implement the functions of the device.
• ALU process arithmetic unit
• the microprocessor 24 periodically scans the matrix 26 of the keypad to determine whether numeric or functional keys have been pressed and scans the coin matrix 25 to determine the quantity and type of coins present in the device.
• the matrices 25 and 27 can be obtained with a single optimised matrix as shown schematically in Figure 6, where the inclined bars indicate the closure of the row- column contact, h the same figure, the arrow F indicates the input signal into the sole matrix 25, 26 coming from the microprocessor 24, whilst the arrow G indicates the output signal from the sole matrix 25, 26 towards the same microprocessor 24.
• the output signal through the arrow G could be represented by a single analogue electrical line that assumes a voltage value that is proportional to the pressed keys through appropriate and known resistor networks and through an analogue-digital converter, not shown in the figures, internal or external to the microprocessor 24.
• the microprocessor 24 also reads the detection amplifier to determine which type of coin is touched by the user and consequently performs specific events:
• the microprocessor 24 can perform all other allowed functions, such as that of clock, date keeper, and other typical functions.
• the operation of the electronic coin holder according to the invention is as follows. After being loaded with the assorted coins in the various denominations, the microprocessor is able to provide on the display 5 the quantity of coins present and the amount available.
• the desired amount, set through the keypad 2, is compared with the amount of coins present in the coin holder.
• the light emitting diodes can be made to blink to signal that the coins are insufficient.
• the blinking may be associated with an acoustic warning.
• the desired amount is broken down into the various denominations of coins that can cover it.
• the light emitting diodes will be lighted. These diodes will be extinguished as the counted coins are extracted from the respective loading and withdrawal channel, or when the key C is pressed, resetting all temporary counters and settings made through the keypad.
• the detection amplifier has the function of signalling to the microprocessor that the user's fingers have touched the coins, so that it is possible consequently to emit an acoustic signal to aid the sight impaired.
• the detection amplifier can be constituted by operational amplifiers or by logic ports in CMOS technology (for instance Schmidt triggers) appropriately polarised and able to assure the logic levels necessary for the microprocessor. The polarisations depend on the characteristics of the electronic components used.
• the electronic coin holder allows: to contain coins in various denominations; - to perform the optimised calculation of the coin denominations necessary to reach a determined amount pre-set by the user; to distribute, in semiautomatic fashion, the coins necessary to reach a determined amount pre-set by the user, as per the optimised calculation; to dispense the coins partially, possibly signalling their insufficiency.
• the coin holder can be used by the sight impaired. All keys, including the digit keys, bear the corresponding Braille symbol. A sight impaired user can lightly touch all coins and, through the detection amplification, those to be extracted will emit a sound signal replacing the lighting of the light emitting diode. When no sound signal is emitted, the sight impaired user is sure of having extracted the number of coins corresponding to the desired amount.
• An equal number of different sound signals can indicate other moments of the operation to the user, for example:
• FIG. 7 a variation of the electronic coin holder according to the invention is shown in which the channels for the loading and withdrawal of rows of coins of different values are arranged in superposed ranks.
• the electronic circuit is situated on the top roof 9, and to the same electronic circuit are brought also the electrical connections of the printed circuit board of the underlying roof 90 of the ranks of channels for loading and withdrawing the coins.
• the reference numbers 8 and 80 designate the related bottoms. Such an arrangement allows to obtain a more compact coin holder, more easily transportable in a pocket or a handbag.
• FIG. 8 a variation of the lateral profile of the coin holder according to the invention is shown, in the part where the open ends of the loading and withdrawal channels are located.
• This profile has half-waves that create indentations designated with the references 35 1---8 and facilitate the extraction of a coin from the related row independently from the rank whereto it belongs.
