Single motor driving device of a facsimile system

A single motor driving device in a facsimile system for operating in a transmission mode, comprising:

• a drive gear directly connected to a motor to alternately rotate in a first direction and in a second and opposite direction in response to a driving force of said motor;
• a first gear rotatably engaged with said drive gear;
• a center gear rotatably engaged with said first gear;
• a first reciprocating gear pivotally connected to said center gear via a first link;
• a second gear disposed adjacent to said first reciprocating gear, for transferring rotational power from said first reciprocating gear when said first reciprocating gear is in contact with said second gear,
• a third gear rotatably engaged with said second gear;
• an automatic feed roller gear rotatably engaged with said third gear;
• a first idler gear rotatably engaged with said automatic feed roller gear;
• a second idler gear rotatably engaged with said first idler gear;
• a transmission roller gear rotatably engaged with said second idler gear, for transferring rotational power from said second idler gear to drive a transmission roller coaxially mounted thereon to feed an original document into the facsimile system;
• and
• a cam gear disposed adjacent to said first reciprocating gear, for controlling movement of said first link to bring said first reciprocating gear in contact with said second gear for operation in said transmission mode.

A single motor driving device usable in a facsimile system for operating in a reception mode, comprising:

• a drive gear directly connected to a motor to alternately rotate in a first direction and in a second and opposite direction in response to a driving force of said motor;
• a first gear rotatably engaged with said drive gear;
• a center gear rotatably engaged with said first gear;
• a first reciprocating gear pivotally connected to said center gear via a first link;
• a second reciprocating gear pivotally connected to said center gear via a second link;
• second and third gears interlocked and disposed adjacent to said second reciprocating gear, for transferring rotational power from said second reciprocating gear when said second reciprocating gear is in contact with said second gear;
• a fourth gear rotatably engaged with said third gear, for transferring rotational power from said third gear to drive a reception roller gear having a reception roller coaxially mounted thereon to feed a recording paper into the facsimile system;
• a lever positioned to lock said second link when said second reciprocating gear is in contact with said second gear;
• and
• a cam gear disposed adjacent to said first reciprocating gear, for controlling movement of said first link and movement of said second link via said lever for operation in said reception mode.

A single motor driving device usable in a facsimile system operable in a copying mode, comprising:

• a drive gear directly connected to a motor to alternately rotate in a first direction and in a second and opposite direction in response to a driving force of said motor;
• a first gear rotatably engaged with said drive gear;
• a center gear rotatably engaged with said first gear;
• a first reciprocating gear pivotally connected to said center gear via a first link;
• a second reciprocating gear pivotally connected to said center gear via a second link;
• a second gear disposed adjacent to said first reciprocating gear, for transferring rotational power from said first reciprocating gear when said first reciprocating gear is in contact with said second gear;
• a third gear rotatably engaged with said second gear;
• an automatic feed roller gear rotatably engaged with said third gear;
• a first idler gear rotatably engaged with said automatic feed roller gear,
• a second idler gear rotatably engaged with said first idler gear;
• a transmission roller gear rotatably engaged with said second idler gear, for transferring rotational power from said second idler gear to drive a transmission roller coaxially mounted thereon to feed an original document into the facsimile system;
• fourth and fifth gears interlocked and disposed adjacent to said second reciprocating gear, for transferring rotational power from said second reciprocating gear when said second reciprocating gear is in contact with said fourth gear;
• a sixth gear rotatably engaged with said fifth gear, for transferring rotational power from said fifth gear to drive a reception roller gear having a reception roller coaxially mounted thereon to feed a recording paper into the facsimile system;
• a lever positioned to lock said second link when said second reciprocating gear is in contact with said fourth gear;
• and
• a cam gear disposed adjacent to said first reciprocating gear, for moving said first link to bring said first reciprocating gear in direct contact with said second gear, and for simultaneously forcing said lever to move upward to allow said second link to rotate to bring said second reciprocating gear in direct contact with said fourth gear for operation in said copying mode.

A single motor driving device usable in a facsimile system operable in a reception back mode, comprising:

• a drive gear directly connected to a motor to alternately rotate in a first direction and in a second and different direction in response to a driving force of said motor;
• a first gear rotatably engaged with said drive gear;
• a center gear rotatably engaged with said first gear;
• a first reciprocating gear pivotally connected to said center gear via a first link,
• a second reciprocating gear pivotally connected to said center gear via a second link;
• second and third gears interlocked and disposed adjacent to said second reciprocating gear, for transferring rotational power from said second reciprocating gear when said second reciprocating gear is in contact with said third gear;
• a fourth gear rotatably engaged with said third gear, for transferring rotational power from said third gear to drive a reception roller gear having a reception roller coaxially mounted thereon to feed a recording paper into the facsimile system;
• a lever positioned to lock said second link when said second reciprocating gear is in contact with said third gear;
• and
• a cam gear disposed adjacent to said first reciprocating gear, for controlling movement of said first link and movement of said second link via said lever for operation in said reception back mode.
