1. A sealed letter formation system that folds an envelope sheet while enclosing a content, provides an envelope having the content enclosed therein, and seals the envelope, the system comprising:
a folder that that is configured to fold a first envelope fold of the envelope sheet before the content is placed on the envelope sheet; a positioner provided downstream of the folder in a conveying direction of the envelope sheet to position the envelope sheet by adjusting displacement of the envelope sheet in a conveyance perpendicular direction perpendicular to the conveying direction of the envelope sheet before placing the content on the envelope sheet and subsequent folding of the envelope sheet to enclose the content; and a switcher that is configured to be selectively placed in a conveying path of the envelope sheet so as to prevent the folder from folding the first envelope fold and to feed the unfolded envelope sheet to the positioner.
