<P>PROBLEM TO BE SOLVED: To provide a packaging device using a stepping motor as a drive source, and including a controller for reliably maintaining a braking state of a drive device. <P>SOLUTION: The packaging device transfers a carried film to a packaging part by a film transfer mechanism part or the like that interlocks with the drive device, completes packaging of a packaged object by the transferred film, and includes an emergency stop switch for stopping the packaging and canceling the stop. The packaging device uses the stepping motor as the drive device 24, and includes: a control circuit 45 which performs pulse control to drive the drive device and receives no power when the emergency stop switch 47 is operated; and a braking circuit 46 maintaining the braking state of the drive device 24. The braking circuit 46 excites the drive device 24 to a static state when the power to the control circuit 45 is cut off, maintains the braking state, and when the pulse control is performed where the control circuit 45 drives the drive device 24, stops the maintained braking state of the drive device 24. <P>COPYRIGHT: (C)2012,JPO&INPIT |
