Claim 3

Dependent Claim 126 words

A combination of facsimile transmitter and receiver according to claim 1, wherein said sheet-like member feeder comprises a guide plate movable between a first and a second position and having an inner surface facing said axis and an arcuate portion disposed concentrically relative to said rotor peripheral surface when said guide plate is in said first position, roller means for feeding said second sheet-like member along said inner surface, and retracting means for moving said guide plate from said first position to said second position, said inner surface extending substantially parallel to said axis when said guide plate is in said first position, said arcuate portion being disposed radially outwardly and away from said rotor peripheral surface when said guide plate is in said second position.

Claim 4

Dependent Claim 162 words

A combination of facsimile transmitter and receiver according to claim 2, wherein said retracting means comprises detector means disposed adjacent said first and second predetermined points for discriminating between presence and absence of said first sheet-like member, a lever operatively coupled to said guide plate and selectively movable between a first and a second position, and means responsive to the result of discrimination for moving said lever between its first and second positions wherein said lever moves said guide plate to its first and second positions, respectively, and said roller means Comprises a first roller rotatably fixed relative to said axis and a second roller carried by said lever, said second roller being urged towards said first roller to feed said second sheet-like member along said inner surface when said lever is in its first position, said second roller being displaced from said first roller to terminate feeding of said second sheet-like member when said lever is moved to its second position.

Claim 5

Dependent Claim 128 words

A combination of facsimile transmitter and receiver according to claim 1, wherein said light conductive device comprises a first and a second light conductor having substantially radial portions adjacent and parallel to one another and extending radially outward along said rotor and having their outer ends adjacent said first predetermined point, said first light conductor extending between the said first predetermined point and said light source, said second light conductor extending between said first predetermined point and said photoelectric device, a lens positioned adjacent the outer end of said second light conductor, said lens having an optical axis aligned with the radial portion of said second light conductor for receiving the light guided through said second light conductor and directing the light passing therethrough into substantially parallel rays.

Claim 6

Dependent Claim 76 words

A combination of facsimile transmitter and receiver according to claim 4, wherein said radially outward end portions are arranged outwardly of said rotor peripheral surface and in close contact with each other, the radially outward end of said first light conductor extending more remotely from said predetermined axis than the radially outward end of said second light conductor and being bevelled to direct the light guided through said first light conductor towards said first predetermined point.

Claim 7

Dependent Claim 79 words

A combination of facsimile transmitter and receiver according to claim 4, wherein said light conductive device comprises a second lens positioned adjacent the outer end of said first light conductor for concentrating the light guided through said first light conductor to said first predetermined point, with said radially outward end portion of said second light conductor extending through the center of said radially outward end portion of said first light conductor and through the center of said second lens.

Claim 8

Dependent Claim 50 words

A combination of facsimile transmitter and receiver according to claim 4, said second light conductor further comprising a second portion extending along the axis of said rotor and having one end thereof adjacent said photoelectric device and being joined at its other end to said radially outward end portion thereof.
