Referring to Fig. 1, the circuit part of coin-feed machine mainly comprises a pick-up unit 10, a sampler 20, a Coin guide device 30, a compare device 40 and a CPU (central processing unit) 50.

Pick-up unit 10 comprises several inductive detectors 11 (at least one), inductive detector 11 has a primary coil 111 and a secondary coil 112, making has the electromagnetic field that forms because of vibration in coin passage, and can produce a pulse signal by secondary coil 112.

After the user inserted coin, coin was passed through by the primary coil 111 of corresponding inductive detector 11 and the oscillating magnetic field between the secondary coil 112, and the pulse signal of secondary coil 112 outputs just can change because of impedance variation.

Sampler 20 also comprises several inductive detectors 21, each inductive detector has primary coil 211 and secondary coil 212, each inductive detector can a corresponding sample coin and is exported a sample-pulse signal Bi, and this sample-pulse signal Bi and inductive detector 11 detected pulse signals are synchronous.Sampler 20 respectively organize the coin that can place the different amount of money on the inductive detector 21 respectively, and as the sample coin.Because the pulse signal that unlike material, different-thickness coin are obtained is neither together, so the sample-pulse signal Bi of inductive detector 21 outputs just can be used as the contrast benchmark that inserts coin.

Compare device 40 has the inductive detector 21 corresponding contrast circuit 41 with sampler 20, each contrast circuit receives the pulse signal of the sample coin that one group of inductive detector 21 of sampler detected respectively, reach the pulse signal that inserts coin that receiving detection device 10 is detected, two pulse signals are compared, if comparative result is that an identical enable signal of then output (enable) send CPU (central processing unit) 50.CPU (central processing unit) 50, comprise microprocessor (cpu) 51, read-only memory (ROM) 52 is used to store the control program of coin-feed machine, and random memory (RAM) 53 is used for writing down the various data computations of coin-feed machine when operation (instruction of the amount of money of the sample coin of respectively organizing in the inductive detector 21 to be placed as sampler 20, the accumulating sum that inserts coin, microprocessor and other data computations etc.).

To set in the control program and respectively organize the amount of money of placing the sample coin in the inductive detector in the sampler 20, utilize earlier during use in the parameter input CPU (central processing unit) 50 of an input interface 57 with each sample coin amount of money, and be stored in the RAM53.As Fig. 1 embodiment totally four groups of inductive detectors 21, place the sample coin of 1 yuan, 5 yuan, 10 yuan and 50 yuan respectively, be 1 yuan, 5 yuan, 10 yuan and 50 yuan just during use with each inductor amount of money parameter setting, this moment, coin-feed machine just can come into operation.When changing coin or changing placement location, all need reset the coin amount of money of each inductor 21.

If in the coin that the user drops into and the sample coin is identical, just output enable signal of contrast circuit 41 accordingly then, CPU (central processing unit) just can be debated and not go out the kind that this inserts coin.If what drop into is counterfeit money, the sampling pulse of the pulse signal of detecting sensor 11 and sample coin must be inequality, contrast circuit 41 no any reactions, so CPU (central processing unit) 50 just can not calculated its amount of money.Owing to set the amount of money of institute's setting-out product coins in the inductor 21 that is cooperated with each contrast circuit 41 in the CPU (central processing unit) 50, so CPU (central processing unit) 50 can not be that mode which group contrast circuit 41 has been exported enable signal is debated the amount of money that does not insert coin and also added up by debating.

CPU (central processing unit) 50 guides to suitable place through control interface 54 control guidance devices 30 with the coin that drops into again and is stored then, and utilize a display interface that accumulating sum and other information are presented on the display device 55, and control the load equipment (as newspaper selling apparatus, duplicating machine, phone etc.) of coin-feed machines through output interface 56.

Referring to Fig. 2, contrast circuit 41 and with the connection layout of inductive detector 11,21.Clock signal generator 411 in the contrast circuit 41 produces the AC pulse and send

inductive detector

11,21, makes

inductive detector

11,21 produce a synchronous oscillating magnetic field.Primary winding 111, the 211 1 end ground connection of

inductive detector

11,21, secondary coil 112,212 1 ends then connect two input ends of a comparer 412 in the comparator circuit 41 respectively.

When in the primary and secondary coil of inductive detector during no coin, the pulse signal Ai of secondary coil 112 outputs is identical with the sample-pulse signal Bi that secondary coil 212 is exported.When having dropped into coin or having placed the sample coin, pulse signal will change.But if the coin that drops into is identical with one of sample coin, pulse signal Ai and the sample-pulse signal Bi of this moment can be quite approaching, otherwise Ai and Bi then have sizable difference.

Comparer 412 is Ai and Bi relatively, if both waveforms are identical, and comparer 412 output " 1 " signals, on the contrary then export " 0 " signal, and send A/D transducer 413 with signal.A/D transducer 413 is then exported a continuous impulse signal when being input as " 1 ", again through output circuit 414 output enable signals.This enable signal is delivered to CPU (central processing unit) 50 backs just can pick out the coin and the amount of money thereof.A/D transducer 413 can't drive the A/D transducer when input " 0 ", thereby does not have any signal output.

The key distinction of slot machine of the present invention and conditional electronic slot machine is the benchmark that adopts the sample coin to differentiate as a comparison, with the pulse signal that is produced and the pulse signal that inserts coin relatively, in the conventional art then in advance with correlation data burning benchmark as differentiation in circuit.
