PROBLEM TO BE SOLVED: To provide, in a belt-type vacuum packaging machine, a mechanism for regularly and surely discharging a packaging bag with an opening sealed without losing a continuous processing function of the belt-type vacuum packaging machine. SOLUTION: The belt-type vacuum packaging machine 17 includes an intermittently moving endless conveyance belt 1 having a plurality of seal bases 4 fixed for sealing the opening 16 of the packaging bag 15. After the side of the opening 16 of the bag 15 reaches a vacuum chamber 12 while mounted on the seal base 4 and vacuumed/sealed, the bag 15 is discharged from a reversing region of the belt 1 to a collection section. One of ends of an L-shaped arm 7 is rotatably pivoted to a side face of the seal base 4, and an opening pressing member 8 in parallel to the sealing direction is provided at the other end. In addition, a horizontal receiving side 9 extending from below a pivoted portion of the arm 7 is formed for fixing a working pin 14 in contact with the lower part of the horizontal receiving side 9 in the vicinity of a discharging section of a body frame 11 of the belt-type vacuum packaging machine.
