The housing guide has lateral protrusions formed on inner surfaces of the paired side sections and protruding to extend close to each other. The screw-type conveyance member has a shaft having a cylindrical shape and a blade member spirally provided on an outer periphery of the shaft such that the blade member protrudes outward from the outer periphery, and is provided to the housing guide such that a part of the shaft and a part of the blade protrude upward in a space between the lateral protrusions and may rotate about a central axis of the shaft. The screw-type conveyance member is provided at an off-center position of the housing guide.
