Bill discriminating apparatus

Claim 2

A bill discrimination apparatus comprising: first and second bill feeding plates confronting each other to form a bill feeding passage having a predetermined clearance therebetween; and a bill conveyor means equipped in said bill feeding passage and a detecting means for discriminating a bill conveyed by said bill conveyer means; wherein said first bill feeding plate is hingedly supported at its base end on said second bill feeding plate; a bill feeding plate opening lever is hingedly supported with a shaft on the swingable end of said first bill feeding plate, urged by a spring means in the same direction as a closing direction of the first bill feeding plate and provided with an engaging hook at its one end and an operating projection at the other end; and an engaging piece formed on an exterior member of said apparatus for engaging with the engaging hook of said bill feeding plate opening lever so that said first bill feeding plate can be positioned to form said bill feeding passage.

Claim 3

A bill discriminating apparatus comprising: a swing unit swingably supported on an exterior member forming a main body, said swing unit comprising a casing, a bill discriminator means provided in the casing and a bottom surface of said casing formed into a first bill feeding plate; a second bill feeding plate being fixed to said exterior member; said swing unit being cooperative with said second bill feeding plate to form a bill feeding passage having a predetermined clearance when said swing unit is swung in a closing direction to make said first bill feeding plate confront said second bill feeding plate; an opening lever swingably supported at a distal end of said casing and having an engaging hook at one end thereof and an operating projection at the other end thereof; an urging means for urging said opening lever in the same direction as said closing direction of said swing unit; said operating projection is provided in such a manner that said opening lever causes a swing motion in a reverse direction to said closing direction against urging force of said urging means when a force for opening said swing unit is given to said operating projection; and an engaging piece, provided on said exterior member, being engaged with said engaging hook of said opening lever to prevent said swing unit from swinging so that said first and second bill feeding plates form the bill feeding passage.

Claim 4

A bill discriminating apparatus comprising: a swing unit swingably supported on an exterior member forming a main body, said swing unit comprising a casing, a bill discriminator means provided in the casing and a bottom surface of said casing formed into a first bill feeding plate; a second bill feeding plate being fixed to said exterior member; said swing unit being cooperative with said second bill feeding plate to form a bill feeding passage having a predetermined clearance when said swing unit is swung in a closing direction to make said first bill feeding plate confront said second bill feeding plate; an opening lever swingably supported at a distal end of said casing and having an engaging hook at one end thereof and an operating projection at the other end thereof; an urging means for urging said opening lever in the same direction as said closing direction of said swing unit; said operating projection is provided in such a manner that said opening lever causes a swing motion in a reverse direction to said closing direction against urging force of said urging means when a force for opening said swing unit is given to said operating projection; and an engaging piece, provided on said exterior member, being engaged with said engaging hook of said opening lever to prevent said swing unit from swinging so that said first and second bill feeding plates form the bill feeding passage.

Claim 5

A bill discrimination apparatus in accordance with claim 2, wherein said opening lever includes an almost rectangular base plate, extension arms extending downward from right and left sides of said base plate, a plurality of bearing pieces extending toward said casing from above said base plate, and an operating projection formed on an upper end of said extension arm and projecting from above said casing in the direction reverse to a direction toward said casing; and each said extension arms has a lower end being formed into said engaging hook protruding toward said casing; further comprising: a shaft laterally provided in said casing at a place adjacent to said distal end for rotatably supporting said bearing pieces; and wherein: said urging means comprises a spring wound around said shaft for urging said engaging hook at the lower end of the extension arm of opening lever toward said casing.

Claim 6

A bill discrimination apparatus in accordance with claim 3, wherein said engaging hook has a tapered guide surface so that, when said swing unit is closed, said opening lever rotates in the reverse direction against urging force of said spring.
