Abstract
Abstract A coin sorting device is disclosed having a coin sorting passage defined between a stationary side plate and a movable side plate openably connected at the upper side thereof to and spaced sidewardly from the stationary side plate, the coin sorting passage is provided with a track movable sidewardly to open the passage downwardly. There is at least one set of coin material detector coils including transmitting and receiving coils positioned in alignment with each other at the opposite sides of the coin sorting passage, respectively for detecting a load impedance of a coin running on the track. Both of the transmitting coils and the receiving coils are opposedly fixed in a stationary retainer fixed in predetermined position relative to the track. This track is adapted for retracting out of the coin sorting passage sidewardly to open the passage downwardly and is positioned in the predetermined position in the passage by a positioning device.

Claim 1
Independent Claim
240 words
A coin sorting device comprising: a stationary side plate; a movable side plate openably connected at the upper side thereof to and spaced sidewardly from said stationary side plate to define a coin sorting passage therebetween; at least one set of transmitting and receiving coils positioned in alignment with each other at the opposite sides of the coin sorting passage, respectively, for detecting a load impedance of a coin; a stationary retainer frame for mounting both of said transmitting coil and said receiving coil in fixed relation in order to maintain a predetermined distance between said coils; and a track for running a coin through said coin sorting passage between said coils which is adapted to retract sideways out of said coin sorting passage to downwardly open the passage so that a coin stopped in said passage between said coils falls therefrom to remove a coin stopped therein; said track being provided on a track portion projecting laterally from the upper end of a plate member which is hinged at a lower end to said stationary side plate and is urged by means of a spring so as to extend said track portion through an opening in said stationary side plate to position said track in said coin sorting passage; said track portion having a tapered shoulder, while said stationary side plate contains a seat for said tapered shoulder so as to position said track in said coin sorting passage.
Claim 2
Dependent Claim
240 words
A coin sorting device comprising: a stationary side plate; a movable side plate openably connected at the upper side thereof to and spaced sidewardly from said stationary side plate to define a coin sorting passage therebetween; at least one set of transmitting and receiving coils positioned in alignment with each other at the opposite sides of the coin sorting passage, respectively, for detecting a load impedance of a coin; a stationary retainer frame for mounting both of said transmitting coil and said receiving coil in fixed relation in order to maintain a predetermined distance between said coils; and a track for running a coin through said coin sorting passage between said coils which is adapted to retract sideways out of said coin sorting passage to downwardly open the passage so that a coin stopped in said passage between said coils falls therefrom to remove a coin stopped therein; said track being provided on a track portion projecting laterally from the upper end of a plate member which is hinged at a lower end to said stationary side plate and is urged by means of a spring so as to extend said track portion through an opening in said stationary side plate to position said track in said coin sorting passage; said track portion having a tapered shoulder, while said stationary side plate contains a seat for said tapered shoulder so as to position said track in said coin sorting passage.
Claim 3
Dependent Claim
209 words
A coin sorting device comprising: a coin sorting passage defined between two side plates; said coin sorting passage having a bottom; at least one set of transmitting and receiving coils being securely positioned in alignment with each other at the opposite sides of the coin sorting passage for detecting a load impedance of a coin passing in the coin sorting passage; a coin running track on which a coin runs through said coin sorting passage in a portion between said coils, said coin running track having a tapered shoulder; said coin running track being provided at the bottom of said coin sorting passage in a portion between said coils; said coin running track being adapted to retract out of the bottom of said coin sorting passage in a sideways direction thereby forming an opening in the coin sorting passage in a downward direction whereby any coins held in said coin sorting passage will fall clearing said coin sorting passage; and one of said plates being stationary and said coin running track being retractably extendable into the coin sorting passage through an opening formed in said stationary plate, said stationary plate having a seat for said tapered shoulder whereby said coin running track is positioned in said coin sorting passage.
Claim 4
Dependent Claim
209 words
A coin sorting device comprising: a coin sorting passage defined between two side plates; said coin sorting passage having a bottom; at least one set of transmitting and receiving coils being securely positioned in alignment with each other at the opposite sides of the coin sorting passage for detecting a load impedance of a coin passing in the coin sorting passage; a coin running track on which a coin runs through said coin sorting passage in a portion between said coils, said coin running track having a tapered shoulder; said coin running track being provided at the bottom of said coin sorting passage in a portion between said coils; said coin running track being adapted to retract out of the bottom of said coin sorting passage in a sideways direction thereby forming an opening in the coin sorting passage in a downward direction whereby any coins held in said coin sorting passage will fall clearing said coin sorting passage; and one of said plates being stationary and said coin running track being retractably extendable into the coin sorting passage through an opening formed in said stationary plate, said stationary plate having a seat for said tapered shoulder whereby said coin running track is positioned in said coin sorting passage.
