Post-processing device and image forming apparatus
A post-processing device includes: a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward; a supporting section that supports the one end of the recording medium loaded on the loading surface; a transporting mechanism that transports a plurality of recording media transported one by one toward the loading section by shifting and stacking the recording media in a transport direction, and sets an amount of shift of the recording media on the basis of a predetermined condition; and a transporting section that bends each of the plurality of recording media transported from the transporting mechanism by applying a transport force to an upper end of each of the recording media opposite to the one end in a state where the one end is in contact with the supporting section, and separates one by one the recording media and loads the recording media on the loading surface.
1 . A post-processing device comprising:
a loading section that has a loading surface directed obliquely upward and in which a recording medium is loaded on the loading surface in a state where one end of the recording medium is directed downward;
a supporting section that supports the one end of the recording medium loaded on the loading surface;
a transporting mechanism that transports a plurality of recording media transported one by one toward the loading section by shifting and stacking the recording media in a transport direction, and sets an amount of shift of the recording media on the basis of a predetermined condition; and
a transporting section that bends each of the plurality of recording media transported from the transporting mechanism by applying a transport force to an upper end of each of the recording media opposite to the one end in a state where the one end is in contact with the supporting section, and separates one by one the recording media and loads the recording media on the loading surface.
2 . The post-processing device according to claim 1 ,
wherein the predetermined condition is a density of an image formed on the recording medium.
3 . The post-processing device according to claim 2 ,
wherein the transporting mechanism
sets the amount of shift as a first amount in a case where the density of the image is a first density, and
sets the amount of shift as a second amount greater than the first amount in a case where the density of the image is a second density higher than the first density.
4 . The post-processing device according to claim 1 ,
wherein the predetermined condition is a basis weight of the recording medium.
5 . The post-processing device according to claim 4 ,
wherein the transporting mechanism
sets the amount of shift as a first amount in a case where the basis weight is a first basis weight, and
sets the amount of shift as a second amount greater than the first amount in a case where the basis weight is a second basis weight greater than the first basis weight.
6 . An image forming apparatus comprising:
an image forming section that forms an image on a recording medium; and
the post-processing device according to claim 1 that executes post-processing on the recording medium on which the image forming section forms the image.
7 . An image forming apparatus comprising:
an image forming section that forms an image on a recording medium; and
the post-processing device according to claim 2 that executes post-processing on the recording medium on which the image forming section forms the image.
8 . An image forming apparatus comprising:
an image forming section that forms an image on a recording medium; and
the post-processing device according to claim 3 that executes post-processing on the recording medium on which the image forming section forms the image.
9 . An image forming apparatus comprising:
an image forming section that forms an image on a recording medium; and
the post-processing device according to claim 4 that executes post-processing on the recording medium on which the image forming section forms the image.
10 . An image forming apparatus comprising:
an image forming section that forms an image on a recording medium; and
the post-processing device according to claim 5 that executes post-processing on the recording medium on which the image forming section forms the image.
