TREATMENT LIQUID APPLICATION APPARATUS

摘要

A treatment liquid application apparatus including an application roller for applying treatment liquid; a press roller for pressing against the application roller an elongated recording medium which is placed between the press roller and the application roller; and a conveyance roller located downstream relative to the application roller on a conveyance path of the recording medium and conveying the recording medium is disclosed. The apparatus includes a control unit for causing the press roller to be pressed against the application roller when a value related to a conveyance amount of the recording medium conveyed by the conveyance roller from a re-start of conveyance exceeds a value corresponding to a slack amount of the recording medium which occurs in an upstream side of the conveyance roller at a stopping of conveyance.

1. A treatment liquid application apparatus comprising:
a first application roller configured to apply treatment liquid; a first press roller configured to press against the first application roller an elongated recording medium which is placed between the first press roller and the first application roller; a conveyance roller located downstream relative to the first application roller on a conveyance path of the recording medium and configured to convey the recording medium; an obtaining unit configured to obtain a first slack amount of the recording medium which is created on an upstream side of the conveyance roller at a stopping of conveyance of the recording medium by the conveyance roller; a conveyance amount calculation unit configured to calculate a value related to a conveyance amount of the recording medium conveyed by the conveyance roller from a re-start of conveyance; a detection unit configured to detect that the value related to the conveyance amount from the re-start of conveyance of the recording medium calculated by the conveyance amount calculation unit exceeds a first value corresponding to the first slack amount of the recording medium; and a control unit configured to cause the first press roller to be pressed against the first application roller when the detection unit detects that the value related to the conveyance amount of the recording medium exceeds the first value corresponding to the first slack amount of the recording medium.
