Media folding device and control method for media folding device

A media folding device comprising:

• a stacking portion on which media transported from an introduction path are placed;
• a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion;
• and
• a bend forming mechanism that includes a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction,
• wherein the bend forming mechanism causes a folding position of the media to be nipped by the folding roller pair by shortening a relative distance between the first abutting portion and the second abutting portion to bend the media toward the folding roller pair,
• wherein the first and second abutting portions shorten the relative distance between them in a state where they both abut the media to be nipped,
• wherein the stacking portion is formed by connecting an upstream member formed upstream in the transport direction and a downstream member formed downstream of the upstream member, and a connection portion between the upstream member and the downstream member is provided at a position corresponding to the folding position when the medium is bent and is configured to switch between a linear state in which the upstream member and the downstream member are flush and a bent state in which the upstream member and the downstream member are connected in a projecting shape toward the folding roller pair side.

A control method for a media folding device that includes a stacking portion on which media transported from an introduction path are placed;

• and a folding roller pair that folds the media at a folding position after the media have been stacked in the stacking portion, comprising:
• bending the media with a folding position at the top toward the folding roller pair by shortening a relative distance between a first abutting portion configured to abut against a front end of the media, which are stacked in the stacking portion, in a transport direction, and a second abutting portion that is configured to abut against a rear end of the media, which are stacked in the stacking portion, in the transport direction;
• nipping with the folding roller pair the folding position of the media that have been bent, wherein the first and second abutting portions shorten the relative distance between them in a state where they both abut the media to be nipped;
• and
• transporting the media by the folding roller pair,
• wherein the stacking portion includes a projecting portion that protrudes toward the folding roller pair at a position corresponding to the folding position when the media are bent.
