Embodiment

Energy saving type intelligence cash inspecting machine, comprise power control circuit, by the voltage adjustment. value sampling partially. charge and discharge circuit. low pressure reduction voltage stabilizing. delay circuit. with the complete circuit module that trigger input circuit constitutes, input terminal voltage is by 9-3.5v, and output end voltage remains on 3.5v output; Power supply cuts off the power supply automatically, and outage back circuit is zero power consumption.

Power supply is directly exported burning voltage through the voltage adjustment by input end by output terminal, (unsettled voltage is taken a sample through inclined to one side value. by inclined to one side value shunting unstable voltage is adjusted into burning voltage output by low pressure reduction voltage stabilizing after the compensation). the process delay circuit is connected with trigger circuit, trigger delay circuit by charge-discharge circuit and become high level, circuit is disconnected fully from low level.

Described control circuit is: (see figure 2)

The other end of the other end of K switch 1 and current-limiting resistance R39, the collector of an end of resistance R 38, the anode of diode D14, triode Q14 is connected;

Principle of work: when button touch-switch K1 does not press, by Q14, Q13, Q17, the voltage-stabilizing output circuit that Q12 forms, not conducting, be in cut-off state, so Q17C utmost point no-voltage output, when K1 presses, supply voltage provides high level to C11 through R41 by D13, make Q14, Q13, the Q12 conducting, same D10, R36, R37, R38, C9, C10, Q17 forms voltage stabilizing output, by R34 C8 is charged after the power on circuitry, make the Q11 collector after the C8 discharge, become high level, make discharge exponential quantity voltage turn-on Q15 from low level, Q16, after the C11 discharge, make Q14, Q13 ends, and realizes closing automatically tester in power-down state, Q11 when currency examine uses intermittently discharges and recharges C8 as the machine circuit, so can not shut down in use.

Above built-up circuit after automatic outage, because not conducting of Q17, so circuit disconnects not power consumption fully, as the need start-up circuit, be pressed the K1 use of just can switching on once more.K2 is the button that manually shuts down, if K2 is pressed in manually shutdown, provides high level that the Q16 conducting is discharged immediately to C11 by R41, and circuit disconnects at once, shuts down.

Using method: after inserting dry cell, press starting switch K1, make circuit be in opening, by former currency examine sensor circuit, put the banknote that to test into, through triggering sensor is detected to true and false banknote, as long as banknote does not take out, machine is in user mode always, in case banknote is removed, machine just can close tester in power-down state by automatic time delay, and circuit zero power consumption of outage back reaches energy saving purposes.It is investigated and read pertinent literature, before the present technique utility model, never, also cut off the technology that present technique is the same or be close of not writing.
