A coin checking device is provided in a coin handling machine for discriminating genuine coins from counterfeit. The coin checking device includes detection coils comprising a transmitting coil for generating an exciting voltage and a receiving coil for generating an induced voltage. The detection coils detect the passage of each coin and sequentially issue signals. The coin checking device also includes a controller which may be a computer. The controller receives signals from the detection coils and makes calculations on the basis of the values of the signals in accordance with a stored program to obtain a reference value. In the controller, the reference value is then compared with a predetermined acceptable value and the degree of any difference in the value thus obtained determines whether the coin is genuine or counterfeit. The reference value in the controller is constantly renewed on the basis of new signal inputs into the controller. The acceptable value can be varied by a coin kind setting switch provided for setting the kinds of coins to be checked.

Coin checking device for use in a coin handling machine

A coin counting and packaging machine performs a counting operation for counting selected coins and accommodating the coins thus counted into a bag and a packaging operation for packaging selected and counted coins with a paper. These operations are selectively performed separately or individually. When the counting operation is carried out in a state that the bag is prepared, coins are scattered in the machine. To avoid this, a detecter is provided for detecting the presence or absence of the bag and a control circuit is provided for control the start of the machine in response to the signal from the detector. The control circuit also make the switching of a counting chute and a packaging chute.

An apparatus for detecting different kinds of coins for use in a coin handling machine includes a coin selecting groove and a cam actuating the coin selecting groove to select the width of the coin selecting groove. Coin kind setting switches are provided for setting the particular kind of coins to be handled in accordance with the material thereof. The coin kind setting switches are actuated by coin kind selecting cams operatively associated with the cam to set detection levels. A detection coil device is provided adjacent to the coin selecting groove and detects the passing coin to issue a level signal in accordance with the material of the coin. A control circuit includes a comparator for comparing the detection levels set by the coin kind setting switches with the level signal detected by the detection coil device to detect an abnormal coin.

Apparatus for detecting different kinds of coins for use in a coin

An electrical circuit arrangement for use in a coin counting device is provided. The arrangement is provided with an abnormality detection circuit for generating an alarm signal when any of the optical sensing member of the coin counting device is hindered from operating normally due to adhesion of dust or other causes. The abnormality detection circuit includes a NAND gate, a NOR gate, an OR gate, a counter and an SR-type flip-flop. The first and second detection signal generated from the optical sensing members are supplied to the NAND gate and the NOR gate. The OR gate is supplied with the output from the NOR gate and a reset signal from a reset operator section. The counter is supplied with the output from the NAND gate and the output from the OR gate. In normal operation, the counter counts the level '1' and '0' of the binary logical level alternately, thereby to leave a counting section to continue the counting operation. If any abnormality occurs at any of the combined optical sensing members, the number counted by said counter takes the value 2, whereupon a second output signal indicating the occurrence of abnormality is generated by the counter and fed to the flip-flop which generates an alarm signal.

Herein disclosed is a counting device for use in a coin sorting and counting apparatus including a coin path for moving coins to be sorted and for guiding the same such that the coins being moved change their courses and leave the coin path in succession at predetermined positions according to the sizes or diameters of the coins. Further included is a coin feeding mechanism for feeding the coin path with the coins one by one. The counting device has a plurality of vibrating elements arranged at the respective positions, where the coins leave the coin path, so that they are vibrated by the coming coins, respectively, when they come into contact. A plurality of vibration sensors are connected with the vibrating elements, respectively, for converting the vibrations of the elements into electric signals. As customary, the calculating means receives the electric signals for separately calculating the numbers and sums of the coins of different sizes.

Herein disclosed is a coin handling apparatus which is free from having its coin guide passage from being jammed with coins when the supply of any more coins is to be stopped. The coin handling apparatus is of the type including, as customary, a rotary disc, a guide passage, a conveyor belt and a coin stacking cylinder. The coin handling apparatus is improved to include a rotary stop pin disposed in the guide passage for normally opening the guide passage and for closing the same thereby to block the succeeding coins, a rotary solenoid for controlling the opening and closing operations of the stop pin, a detecting device for detecting the coin, which is to pass therethrough in the guide passage, thereby to generate two outputs, a coin stop control unit for operating a controlled stop signal in accordance with both the outputs of the detecting device and a stop signal, and a drive circuit for driving the rotary solenoid in accordance with the controlled stop signal thereby to effect the closing operation of the rotary stop pin. The detecting device has a pair of photo-sensors for optically detecting the position of the coin just passing therethrough, and a coin detecting unit connected with the photo-sensors for converting the position of the coin into a binary logic level.

A coin counting system for use with a coin handling apparatus such as a coin counting apparatus, a coin sorting apparatus or a coin wrapping apparatus includes a coin guide for guiding a series of coins to be counted therealong and a belt conveyor for conveying the coins in the guide. A light source is disposed at a downstream portion of the guide. Pre- and post-sensors are juxtaposed to each other upstream and downstream in the coin conveying direction and are arranged to receive the light from the light source and to be included temporarily within the generally triangular space, which is defined by the inner wall of the coin guide and by the facing circumferential portions of the two coins being conveyed adjacent to each other, thereby to generate respective signals. A generator circuit is made receptive of the signals of the two sensors for generating an addition signal, when the two coins pass in the normal order from the pre-sensor to the post-sensor, and a subtraction signal when the two coins pass in the abnormal order from the post-sensor to the pre-sensor. Structure is made responsive to the addition and subtraction signals of the control circuit for generating a count signal, when in the normal order, but not when in the abnormal order. A counter counts up the number of the coins in response to the count signal. Thus, the coin having been counted can be prevented from being erroneously counted up even if it is conveyed backward.
