<P>PROBLEM TO BE SOLVED: To obtain a packaging device capable of drawing a packaging sheet from a sheet roll in such a state that breakage or the like hardly occurs by a drawing mechanism having a simple structure. <P>SOLUTION: A roll support roller 21 placing and supporting a sheet roll 7 is freely rotatably provided in a packaging sheet housing 20. A motor 25 driving the roll support roller 21 is provided. A drawing mechanism 30 is constituted so that both ends in a direction orthogonal to a packaging sheet drawing direction of the packaging sheet 5 are held by a pair of holding parts 32 and 32 to draw the packaging sheet 5 from the sheet roll 7. A control means is provided which controls the drive of the drawing mechanism 30 while controlling the drive of the motor 25 so that the roll support roller 21 is rotated and driven by the motor 25 and the sheet roll 7 is rotated and operated in a packaging sheet pay-out direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
