Abstract

PURPOSE:To facilitate disassembly of a metal detection machine at the time of cleaning it by integrating each part which constitutes a conveyance means and constituting it in such a manner that it can be mounted and dismounted on a base freely. CONSTITUTION:A main roller 3 which constitutes a conveyance means 10 as a conveyor, a follow-up roller 4, a conveyance belt 5, and a receive base 6 are formed integrally and constituted in such a manner that they can be mounted and dismounted on a base 1 freely. When the conveyance belt 5 is driven, a main gear 3a of the main roller 3 is brought into contact with a both teeth timing belt 17 of a drive means 13 provided on the base 1 to obtain driving force. Since the conveyance means 10 is constituted in such a manner that it can be connected to and separated from the both teeth timing belt 17 easily, it is possible to mount and dismount the conveyor easily at the time of cleaning.
