Abstract
A decurling device includes: a pair of decurling units configured to correct curl of a recording medium by sandwiching the recording medium; a switching unit configured to switch the pair of decurling units between a first state in which a pressure contact force is relatively large and a second state in which the pressure contact force is smaller than that in the first state; a release unit configured to release a pressure contact between the pair of decurling units; and a restricting unit configured to restrict release of the pressure contact between the pair of decurling units when the pair of decurling units are in the first state.
Claims19
A decurling device comprising:
- a pair of decurling units configured to correct curl of a recording medium by sandwiching the recording medium;
- a switching unit configured to switch the pair of decurling units between a first state in which a pressure contact force is relatively large and a second state in which the pressure contact force is smaller than that in the first state;
- a release unit configured to release a pressure contact between the pair of decurling units;
- and
- a restricting unit configured to prohibit release of the pressure contact between the pair of decurling units when the pair of decurling units are in the first state;
- and
- an opening and closing unit provided in an apparatus body so as to be openable and closable,
- wherein the restricting unit prohibits opening of the opening and closing unit when the pair of decurling units are in the first state.
A decurling device comprising:
- first and second decurling means for correcting curl of a recording medium by sandwiching the recording medium;
- switching means for switching the first and second decurling means between a first state in which a pressure contact force is relatively large and a second state in which the pressure contact force is smaller than that in the first state;
- release means for releasing a pressure contact between the first and second decurling means;
- and
- restricting means for prohibiting release of the pressure contact between the first and second decurling means when the first and second decurling means are in the first state;
- and
- an opening and closing unit provided in an apparatus body so as to be openable and closable,
- wherein the restricting unit prohibits opening of the opening and closing unit when the pair of decurling units are in the first state.
