Conveyance path forming body and conveying machine

A conveyance path forming body comprising:

• a first surface that is, disposed on an opposite side of a sheet to a processing unit disposed on a side of one surface of the sheet being conveyed along a conveyance path to perform processing on the one surface;
• a second surface that is disposed at a downstream of the first surface in a conveying direction of the sheet so as to be more distant from the processing unit than a hypothetical extension surface of the first surface;
• a third surface that is disposed at a downstream of the second surface in the conveying direction of the sheet so as to be continuous with the second surface and to be inclined from a hypothetical extension surface of the second surface toward a side of the processing unit;
• a first contact portion to come into contact with the one surface of the sheet at an upstream of a processing position of the processing unit in the conveying direction of the sheet;
• and
• a second contact portion to come into contact with a surface, opposite to the one surface, of the sheet at an upstream of the first contact portion;
• the first, second and third surfaces facing the sheet conveyed along the conveyance path and being guide surfaces that come into contact with the sheet;
• the first surface extending to a downstream end of the processing unit;
• in a direction going from the processing unit to the sheet, a position at which the first contact portion is to come into contact with the sheet being more distant from the processing unit than a position at which the second contact portion is to come into contact with the sheet.
