Rotary disk speed control in automatic coin processing apparatus

Claim 2

A coin processing apparatus having: a rotary disk for continuously sending out coins; a coin passageway for alining in a row and transferring the coins thus sent out from the rotary disk; driving means for rotating the rotary disk; speed-changing means connected to the rotary disk and driving means and operating to change the rotational speed of the rotary disk; and selection means for selecting the rotational speed of the rotary disk in accordance with the kind of coin, and characterized in that the rotational speed of the rotary disk is caused to be a coin sending-out speed in accordance with the kind of coin.

Claim 3

In a coin processing apparatus of the type including a rotary disk on which coins to be processed are deposited, a coin passageway extending substantially radially outwardly from said rotary disk such that said coins are centrifugally sent out into said coin passageway from said rotary disk one by one, and an electric motor adapted to impart rotation to said rotary disk, a device for changing the speed of rotation of said rotary disk in accordance with the diameters of the coins deposited thereon, said device comprising: a drive circuit for driving said motor, said drive circuit comprising a power supply connected to said motor and an element controlled by an external signal to regualte the flow of current from said power supply to said motor; and a motor speed control circuit for supplying said signal to said element of said drive circuit in order to control the speed of said motor, said motor speed control circuit comprising means for producing said signal, and means for changing the frequency of said signal in accordance with the diameter of the coins deposited on said rotary disk.

Claim 4

In a coin processing apparatus of the type including a rotary disk on which coins to be processed are deposited, a coin passageway extending substantially radially outwardly from said rotary disk such that said coins are centrifugally sent out into said coin passageway from said rotary disk one by one, and an electric motor adapted to impart rotation to said rotary disk, a device for changing the speed of rotation of said rotary disk in accordance with the diameters of the coins deposited thereon, said device comprising: a drive circuit for driving said motor, said drive circuit comprising a power supply connected to said motor and an element controlled by an external signal to regualte the flow of current from said power supply to said motor; and a motor speed control circuit for supplying said signal to said element of said drive circuit in order to control the speed of said motor, said motor speed control circuit comprising means for producing said signal, and means for changing the frequency of said signal in accordance with the diameter of the coins deposited on said rotary disk.

Claim 5

The device as recited in claim 2, further including a motor speed adjusting circuit connected to said motor speed control circuit for automatically readjusting the speed of said motor substantially to a constant value in the event of a change in the load on said motor, said motor speed adjusting circuit comprising a tachometer generator driven by said motor, and means responsive to a change in the output voltage from said tachometer generator to correspondingly change the frequency of said signal delivered from said motor speed control circuit to said element of said drive circuit.

Claim 6

In a coin processing apparatus of the type including a rotary disk on which coins to be processed are deposited, a coin passageway extending substantially radially outwardly from said rotary disk such that said coins are centrifugally sent out into said coin passageway from said rotary disk one by one manually operable means for adjusting the width of said coin passageway in accordance with the diameters of the coins deposited on said rotary disk, and an electric motor for imparting rotation to said rotary disk, a device for changing the speed of rotation of said rotary disk in accordance with the diameters of the coins deposited thereon with relation to the width of said coin passageway, said device comprising: a drive circuit for driving said motor, said drive circuit comprising a power supply connected to said motor and an element controlled by an external signal to regulate the flow of current from said power supply to said motor; and a motor speed control circuit for supplying said signal to said element of said drive circuit, in order to control the speed of said motor, said motor speed control circuit comprising means for producing said signal, and means operated by said manually operable means to change the frequency of said signal whereby the speed of rotation of said rotary disk and the width of said coin passageway are simultaneously adjusted in accordance with the diameter of the coins deposited on said rotary disk.

Claim 7

In a coin processing apparatus of the type including a rotary disk on which coins to be processed are deposited, a coin passageway extending substantially radially outwardly from said rotary disk such that said coins are centrifugally sent out into said coin passageway from said rotary disk one by one manually operable means for adjusting the width of said coin passageway in accordance with the diameters of the coins deposited on said rotary disk, and an electric motor for imparting rotation to said rotary disk, a device for changing the speed of rotation of said rotary disk in accordance with the diameters of the coins deposited thereon with relation to the width of said coin passageway, said device comprising: a drive circuit for driving said motor, said drive circuit comprising a power supply connected to said motor and an element controlled by an external signal to regulate the flow of current from said power supply to said motor; and a motor speed control circuit for supplying said signal to said element of said drive circuit, in order to control the speed of said motor, said motor speed control circuit comprising means for producing said signal, and means operated by said manually operable means to change the frequency of said signal whereby the speed of rotation of said rotary disk and the width of said coin passageway are simultaneously adjusted in accordance with the diameter of the coins deposited on said rotary disk.
