  • the printed paper is enclosed in the envelope using a desk type enclosing-sealing machine with a relatively simple structure or manually so that the envelope is sealed.
  • a desk type enclosing-sealing machine with a relatively simple structure or manually so that the envelope is sealed.
  • There is an apparatus that automatically processes a series of operations of printing, enclosing and sealing is costly and requires a wide installation area. It has therefore been difficult for the user who does not frequently need preparation of the DM to purchase such apparatus.
  • Patent Literature 1 discloses the enclosing-sealing machine usable as the desk type enclosing-sealing machine as described above which is provided with sheet folding means configured to fold the sheet to be enclosed in the envelope.
  • This machine includes an automatic sheet feeding unit that automatically feeds the uppermost sheet from a pile of provided sheets to the sheet folding means, and manual sheet feeding means that feeds a manually supplied sheet to the sheet folding means, and is configured to select and drive the sheet feed mode from the automatic sheet feed mode, manual sheet supply mode, and a mix mode that allows the sheet feed from the automatic sheet feeding unit and the manual sheet feeding means simultaneously.
  • the present invention has been made with regard to the aforementioned problem, and is intended to provide a sealed letter preparing apparatus configured to have the envelope (or sheet to be formed as the envelope), and the necessary enclosure sheet (which is not necessarily required) printed thereon, enclose the enclosure in the envelope, and seal the envelope for formation of the sealed letter.
  • the apparatus with simple and compact structure hardly causes the problem of enclosing error, such as enclosing failure and enclosing of wrong enclosure. This allows users to prepare the sealed letter efficiently by themselves, especially suitable for preparation of one-to-one direct mail.
  • a sealed letter preparing apparatus as claim 1 performs printing on an envelope and an enclosure, and enclosing the enclosure in the envelope so as to be sealed to form a sealed letter, which includes a printing unit that performs printing on the envelope and the enclosure, respectively for each of the sealed letters to be prepared, a first carrier passage that carries the envelope printed by the printing unit, a second carrier passage that carries the enclosure printed by the printing unit, and enclosing-sealing means located at a position where the first passage and the second passage join, which performs sealing after enclosing the enclosure in the envelope.
  • the envelope is formed by folding a sheet to be formed as the envelope
  • the first carrier passage is provided with first folding means that folds the sheet to be formed as the envelope into a shape of the envelope
  • the enclosing-sealing means performs sealing after enclosing the enclosure in the sheet folded by the first folding means to be formed as the envelope.
  • the enclosure is formed by folding the sheet to be formed as the enclosure
  • the second carrier passage is provided with an alignment member that holds the sheet to be formed as the enclosure
  • second folding means that folds the sheet to be formed as the enclosure held at the alignment member

  • envelope used herein refers not only to the pouch-like envelope in the ordinary sense but also to the sheet before it is folded and formed into the pouch-like envelope.
  • the envelope in the ordinary sense may be commercial or ready-made article, or self-produced.
  • the enclosure is enclosed in the envelope as needed. Therefore, in the case where no enclosure is required to be enclosed in the envelope for sealing, the resultant sealed letter without enclosure may be regarded as the sealed letter to be formed by the sealed letter preparing apparatus according to the present invention.
  • the sheet as the enclosure does not have to be folded to be enclosed in the envelope. The sheet may be enclosed in the envelope as it is printed.
  • the sealed letter preparing apparatus is configured to allow a common printing unit for printing both the envelope and the enclosure to perform printing on the envelope and the enclosure alternately for each of the sealed letters to be prepared.
  • the printed envelope is carried on a dedicated first carrier passage
  • the printed enclosure is carried on a dedicated second carrier passage so that the enclosing-sealing means provided at a junction of those carrier passages makes a pair of the envelope and the enclosure without error, encloses the enclosure in the envelope, and seals the envelope for formation of the sealed letter.
  • the apparatus is suitable for preparation of one-to-one direct mail having the enclosure different for the respective envelopes. Especially when preparing the sealed letter using the ready-made envelope, the apparatus ensures to perform a series of operations including printing the envelope and the enclosure, enclosing the enclosure, and sealing the envelope full-automatically with no errors.
