Is further provided with a movable member that can be displaced from a cutting position substantially overlapping with the sticking position to a retracted position in the pulling direction. In this case, due to the displacement of the tape cutting part, interference between the tape cutting part and the end of the paper piece supply part can be avoided, and the protrusion of the adhesive tape tip can be reliably prevented.

  In the above apparatus, it is preferable that the movable member has a restoring unit that applies a force to return the tape cutting unit displaced to the retracted position to the cutting position, and supplies a piece of paper when placing one piece of paper at the pasting position. The tape cutting part is allowed to move from the cutting position to the retracted position against the restoring means according to the operation of the part. In this case, the tape cutting unit can be reciprocated between the cutting position and the retracted position in accordance with the operation of the paper piece supply unit.

  In the above apparatus, preferably, the contact means is opposed to one piece of paper supported at the attaching position by the end of the paper piece supply unit across the front end portion of the adhesive tape and the front end portion from the non-adhesive surface side. A pressing member that can be pressed; and an interlocking member that urges an end portion that supports one piece of paper in conjunction with the pressing member toward the adhesive surface of the tip portion. In this case, the pressing member is displaced toward the front end portion of the adhesive tape, so that the front end portion of the adhesive tape and one sheet of paper can be sandwiched and pressed from both sides.

  In the above apparatus, preferably, the tape cutting unit is erected above the end of the paper piece supply unit so as to be close to one piece of paper, and the contact means sandwiches the leading end portion of the adhesive tape.
