Sheet conveyor and ink-jet recording apparatus

A sheet conveyor, comprising:

• a shaft defining an axis that extends in a first direction;
• an arm pivotable about the axis;
• a supply roller provided on the arm and configured to supply a sheet;
• a first frame formed of metal and supporting the shaft;
• a first conveyance roller configured to convey the sheet supplied from the supply roller;
• and
• a second frame formed of metal and supporting the first conveyance roller, wherein the second frame includes two contact plate portions, which are spaced apart from each other in the first direction, each having a contact surface that is held in contact with the first framed and an extending portion positioned between the two contact plate portions in the first direction and formed such that an end of the second frame is bent in a direction intersecting the contact surface, and
• wherein the second frame is coupled at the contact plate thereof to the first frame.

An ink-jet recording apparatus, comprising:

• a recording head;
• a carriage on which the recording head is mounted;
• a guide rail holding the carriage such that the carriage reciprocates along the first direction;
• and
• a sheet conveyor, comprising:
• a shaft defining an axis that extends in a first direction;
• an arm pivotable about the axis;
• a supply roller provided on the arm and configured to supply a sheet;
• a first frame formed of metal and supporting the shaft;
• a first conveyance roller configured to convey the sheet supplied from the supply roller;
• and
• a second frame formed of metal and supporting the first conveyance roller,
• wherein the second frame includes (a) a contact plate portion shaped like a plate and having a contact surface that is held in contact with the first frame and (b) a wall portion extending from the contact plate portion in a direction intersecting the contact surface, and
• wherein the second frame is coupled at the contact plate portion thereof to the first frame
• wherein the guide rail is supported by the second frame.

• wherein the second frame is coupled at the contact plate portion thereof to the first frame,
• wherein the arm is located at an intermediate position of the first frame in the first direction,
• wherein the second frame includes two contact plate portions, each as the contact plate portion, which are located at opposite ends of the second frame in the first direction, and
• wherein the first frame is bent in a direction perpendicular to the first direction.
