The present disclosure is directed to a method that includes capturing images of a working area that includes indicia of a virtual keyboard having a plurality of keys and detecting a selected key of the plurality of keys. The keypad is removably secured to the body and coupled to a processor. Thereby, since the moving member having the pull-in member mounted thereon also moves, the recording medium can be carried into the inside of the apparatus. A center point and centerline of the absorbent article is calculated using the position of the first edge and the second edge. This new magnetic circuit increases the attracting force of the electromagnet when a clearance between the movable member and the electromagnet is greater than a predetermined clearance.
