DE2334700A1 - Coin operated gambling machine - has credit decade counter and holding timing input at given logic level - Google Patents

Abstract

A gambling machine has electronic credit control with a decade counter. One decade output is connected through a capacitor of a few nf to one input of an EXCLUSIVE-OR-gate held at a given logic level by a resistor and through a further capacitor of a few hundred pF to the other input of the gate which is held at a different level by two resistors. The gate output is connected by a pulse-lengthening monostable flip-flop and one or more further gates to a signal amplifier, so that when the logic level at the decade output changes, a pay-out motor is energised and an appropriate coin is paid out.

Slot machine with electronic Coin presentation storage and return Addendum to patent (P 22 51 97 ^ .0)

, (Ρ 22 51 97 ^ .0), is a mime game

gcr.'it with electronic! - coin presentation storage and return UiVuGi LJehutz, in which every type of coin and every profit amount a bistable multivibrator is assigned which, according to its assigned value, a number of pulses of a multivibrator to a multi-stage decadic reference counter lets through.

With such a coin-operated machine, an ici template is used The saved amount is paid out when the player has pressed a return key, with a toggle on the logical Level L is set. In addition, when the game is over, an electronic timer is over a corresponding one Output blocked and the coin return via a corresponding Entrance initiated.

is built that can hold the Taktein- {tan ?, in the rest position to a particular logic level when handoff of the counter.

For this purpose, it is proposed according to the present additional invention, that at an output of decades of an electronic flow meter a capacitor of a few nanofarads with the input of an exclusive-or gate held at a logic level via a resistor and another capacitor of a few hundred picofarads with the one above two resistors Another input of the exclusive-or-gate held another logic level is connected, that a monostable multivibrator is provided for pulse lengthening and that the output of the exclusive-OR gate via the monostable multivibrator and is interconnected via one or more gates with a signal amplifier, so that when the state of the logical Level at the output of the decades the payout motor starts up and one your counted value is paid out corresponding to the coin.

Further refinements of the invention are set out in the subclaims to find.

In Fig. 1 the original counter from up-down counting decades is 1 built with outputs Qi, Q2, Q3 and Q ^, the output of which is Ql its state changes during the first clock edge if the counter changes, for example, from a logic level L to a logic level H is switched on via the clock input, the clock input is in the rest position at the logic level L held.

When the return button is pressed to initiate the return of coins and when the electronic timer has reached zero, signals are sent that are linked to one another. The switching edge that occurs when the two signals are combined is sent to the clock input of the counting decades, with the logic level at output J being changed. This change is coupled to an exclusive-OR gate 3 via two capacitors 2a, 2b, so that a pulse arises on both the positive edge and the negative edge at the output of the exclusive-OR gate, which is extended by triggering a monostable multivibrator h will. This pulse is linked to the count signal and the return signal via a NAND gate 5, the output signal of which via a signal amplifier 6 causes eiien payout motor 7 to start rotating from its zero position.

The payout motor 7 drives a payout slide 16 via a gear 14, 15 (Fig.5), which is provided with a gate 16 '(Fig. H) , in which a roller attached to the driven gear lh engages, so that with one revolution this gear wheel dex payout slide performs a forward and a return stroke. A coin stacking tube 18 is arranged above the front end of the payout slide, from which a coin is pushed out with each stroke of the payout slide, the strength of which is a little less than that of a coin.

A diaphragm 19 (Fig. 3) - or optionally an additional diaphragm 19 ^f (Fig. 5) - is connected to the gear Ik driven by the payout motor 7, which interrupts a light barrier 8 in the zero position. Outside the zero position of the gear 14 and thus of the payout slider l6, the closed light barrier causes the payout motor to continue running over the duration of the pulse arriving from the monostable multivibrator h back to the zero position. As soon as the shutter 19 interrupts the light barrier S, a countdown pulse is given to the clock input of the counting decade 1 if the counter is not yet at zero. This pulse again triggers a level change at output Q1, so that the monostable multivibrator is retriggered via the exclusive-OR gate 3 and the payout device ejects the next coin.

This self-controlling circuit is necessary so that in case of failure of the counting of the master counter the coin tubes not completely empty paid v / ground, which for the installer Toller such Münzspiclgcrätes certainly a significant loss Ij ed ou t s x n i e rd.

The actual payout process is ended when the corresponding counting decade 1 is zero. For this purpose, a Nullütellungsdekoder 9 (Fig. 1) is connected to the counting decade, which blocks the clock input of the counter, the nionostabi-Ie flip-flop h and the signal amplifier 6 for the payout motor when it is set to zero. If the shutter 19 now interrupts the light barrier U , the impulse triggered thereby can no longer reach the clock input of the counter.

This also includes shaded pole motors for driving the payout device can be used, the after-run of the payout motor that occurs when switching off must be suppressed in order to achieve a defined To get zero position. For this purpose, according to the invention

Switching off the alternating voltage to the coil 7 'of the payout motor (A1) I). 3) lived a DC voltage for a certain period of time. This UDC voltage UiV c -generates a rectified kagneti'old, in which the rotor 7 ^{11 of the} pay-out motor rotates, Dadurcii is induced in the rotor an eddy current, whose electrical motor counteracts the rotary motion of the rotor according to the well-known principle of the eddy current brake.

The control functions work as follows:

A resistor is connected to the base of transistor Tl (Fig.2) Rl applied by control electronics, not shown, the logic level JI. As a result of the logical Level, the transistor becomes conductive and pulls a relay Hol 15 in the collector circuit. Its associated changeover contact ilel 1 switches from the position shown to the other Position and thus logs the payout rotor 7 to its operating weehool voltage, so that the rotor is set in rotation. With the stop signal, i.e. when the logic level L is at the base of Transistor T1 is applied, the relay HeI 13 drops out again and its changeover contact ReI 1 switches to the starting position return. Zener diodes D2 and D3 limit the self-induction voltage and suppress the spark at the changeover contact and dex- lying in series with a limiting resistor RS Capacitor C2.

As long as the relay ReI 13 is picked up, i.e. as long as the transistor Tl is turned on, are transistors T2, Ϊ3 and Ta blocked If the relay .IeI 13 drops out, the collector is from transistor Tl via the coil of the relay to + Ul voltage, which via resistor Il'i the transistor T3 and thus also the tran-

at
sistor T'V suitable choice of the resistor combination H5, Rb and 117 turns on, while the transistor T2 remains blocked. The payout motor 7 is now connected to + Ul voltage via the changeover contact ReI 1 and the transistor T-'i and is braked. Ubiquitous

At the same time, capacitor C1 at the base of transistor T2 is charged via resistor 112 of the voltage divider made up of resistors R2 and 113. When the capacitor Cl is charged up to the visual wave voltage of the transistor T2, the transistor turns on and the transistors T3 and Th are blocked. As a result, the Drems current is automatically switched off according to the time constant given by R2 / C1, and the Unischaltkontalct HeI 1 can switch over when starting again without a switch-off peak voltage occurring. Diode Dl is provided for short-circuiting self-induction voltages arising in the coil of relay Ilel 13.

Further modifications and variations of the exemplary embodiment are possible for those skilled in the art and are considered to fall within the scope of the invention.
