Pull up the rewind knob so the film cartridge can be inserted in the room.
Then, return the knob and insert the film tip in the socket of the take-up spool.
Depress the wind releasing button, and turn the film wind knob in the direction of the arrow so the film rolls around the spool rightly.
Here, the film isn't transported rightly unless the rewind knob turns counterclockwise. (shown in the right figure.)
