Claim Text:
1. A heat processing device having a treatment section sandwiched between a first conveyance apparatus positioned on an upstream side of the treatment section and a second conveyance apparatus positioned on a downstream side of the treatment section, comprising: right and left support members provided in the treatment section in rightward and leftward spaced relation for supporting an object to be treated, at least either of the right and left support member being free to move in the transverse direction of the treatment section, at least one first conveyance rod arranged in the first conveyance apparatus and capable of a reciprocating motion in a longitudinal direction of the first conveyance apparatus for conveying the object to the treatment section, a pair of first conveying rail members provided in the first conveyance apparatus for supporting the object, at least either of the first conveying rail members being movable in the width direction of the first conveyance apparatus as at least one first movable conveying rail member, a second groove formed in the at least one first movable conveying rail member in which the first conveyance rod is reciprocatably arranged, a first spacing adjustment mechanism provided in the first conveyance apparatus for adjusting the spacing between the first conveying rail members according to widths of the object, a first switching mechanism arranged in the first conveyance apparatus that causes the first conveyance rod to perform an axial rotation in a forward or reverse direction around an axis line thereof, at least one first pusher member on the first conveyance rod, the first pusher member assuming an engagement position in which the first pusher member engages with the object and a retracted position in which the first pusher member departs from the object by causing the first switching mechanism to go into action, at least one second conveyance rod arranged in the second conveyance apparatus and capable of a reciprocating motion in a longitudinal direction of the second conveyance apparatus for conveying the object out of the treatment section, a pair of second conveying rail members provided in the second conveyance apparatus for supporting the object, at least either of the second conveying rail members being movable in the width direction of the second conveyance apparatus as at least one second movable conveying rail member, a third groove formed in the at least one second movable conveying rail member in which the second conveyance rod is reciprocatably arranged, a second spacing adjustment mechanism provided in the second conveyance apparatus for adjusting the spacing between the second conveying rail members according to widths of the object, a second switching mechanism arranged in the second conveyance apparatus that causes the second conveyance rod to perform an axial rotation in a forward or reverse direction around an axis line thereof, at least one second pusher member on the second conveyance rod, the second pusher member assuming an engagement position in which the second pusher member engages with the object and a retracted position in which the second pusher member departs from the object by causing the second switching mechanism to go into action, wherein a movable support member in the treatment section has a first groove into which the second conveyance rod is inserted, and the spacing between the right and left support members in the treatment section is adjusted by displacing the second conveyance rod in the width direction of the second conveyance apparatus, with the second conveyance rod inserted into the first groove.
