Abstract
A liquid coating device includes a coating roller, a supply roller, a pressure roller, a first separator, a second separator, and a sheet receiver. The coating roller coats a sheet with liquid. The supply roller supplies the liquid to the coating roller. The pressure roller sandwiches the sheet, together with the coating roller. The first separator separates the sheet coated with the liquid, from the coating roller. The second separator separates, from the supply roller, a sheet that has not been separated by the first separator and has reached the supply roller. The sheet receiver forms a storage space to accommodate at least a portion of the sheet that has been separated from the supply roller by the second separator.

A liquid coating device comprising:
- a coating roller to coat a sheet with liquid;
- a supply roller to supply the liquid to the coating roller;
- a pressure roller to sandwich the sheet, together with the coating roller;
- a first separator to separate the sheet coated with the liquid, from the coating roller;
- a second separator to separate, from the supply roller, a sheet that has not been separated by the first separator and has reached the supply roller;
- a sheet receiver forming a storage space to accommodate at least a portion of the sheet that has been separated from the supply roller by the second separator;
- and
- a guide to guide the sheet to a position at which the sheet is sandwiched with the coating roller and the pressure roller,
- wherein the guide includes an upper guide plate and a lower guide plate to regulate movement of the sheet in a vertical direction orthogonal to a conveyance direction of the sheet, and
- wherein the sheet receiver is disposed on the lower guide plate.
A liquid coating device comprising:
- a coating roller to coat a sheet with liquid;
- a supply roller to supply the liquid to the coating roller;
- a pressure roller to sandwich the sheet, together with the coating roller;
- a first separator to separate the sheet coated with the liquid, from the coating roller;
- a second separator to separate, from the supply roller, a sheet that has not been separated by the first separator and has reached the supply roller;
- a sheet receiver forming a storage space to accommodate at least a portion of the sheet that has been separated from the supply roller by the second separator;
- and
- a multi-stage roller assembly including:
- a first supply roller to draw up the liquid from a liquid storage portion;
- a second supply roller to equalize an amount of the liquid drawn up to be applied to the sheet on the coating roller;
- and
- the supply roller to supply the liquid equalized by the second supply roller to the coating roller.
A liquid coating device comprising:
- a coating roller to coat a sheet with liquid;
- a supply roller to supply the liquid to the coating roller;
- a pressure roller to sandwich the sheet, together with the coating roller;
- a first separator to separate the sheet coated with the liquid, from the coating roller;
- a second separator to separate, from the supply roller, a sheet that has not been separated by the first separator and has reached the supply roller;
- a sheet receiver forming a storage space to accommodate at least a portion of the sheet that has been separated from the supply roller by the second separator;
- and
- an elastic member to bias the coating roller in a direction away from the supply roller,
- wherein the coating roller is in contact with the supply roller in a state in which the pressure roller is in a pressing state and is not in contact with the supply roller in a state in which the pressure roller is in a pressure-released state.
