摘要:
The present invention provides a liquid application device, an inkjet recording apparatus and a recording apparatus, which are capable of performing an adequate application initial operation according to the length of waiting time and power-off time, as well as a method of controlling the liquid application device. In the present invention, information on an end time of the previous processing for collecting liquid is read from a nonvolatile memory, current time information indicating the current time is obtained, and information on a lapse of time from the end time of the previous collection to a start time of the current application. Thereafter, the number of preliminary rotations R of an application roller is decided based on the information on the lapse of time with reference to a look-up table. Sequentially, the application roller is rotated by the decided number of preliminary rotations R to perform preprocessing operation.

摘要:
In a liquid application device and an inkjet recording apparatus, even if the number of liquid storage units is increased, the number of parts can be reduced, and cost reduction and miniaturization can be realized. The liquid application device includes a buffer tank storing application liquid to be supplied to a space-creating base. Additionally, the device includes an exchange tank storing application liquid to be refilled in the buffer tank. Moreover, the device includes first and second channels linking the buffer tank and the space-creating base, a pump arranged in the second channel, and a third channel linking a T-shaped channel and an exchange tank. Furthermore, the device includes a first valve which switches shutoff and link between first and second tubes, and a third valve which switches shutoff and link between third and fourth tubes.

The present invention provides a liquid application device and an inkjet recording apparatus which are capable of reducing harmful effects resulting from an increase in the number of times of using an application member (for example, a roller). An embodiment of the present invention includes: a supply port for supplying application liquid to a liquid retention space; and a collection port for collecting the application liquid from the liquid retention space, wherein the liquid is applied by a application member in a state where a negative pressure of the collection port is larger than that of the supply port. In such a configuration, the liquid supply port is arranged at a position relatively close to a transferring reference, and the liquid collection port is arranged at a position relatively far from the transferring reference.

The present invention provides a liquid application device and an inkjet recording apparatus, which are capable of reducing nonuniformity in application of liquid onto a recording medium, and thereby forming high-quality images on a steady basis. In the present invention, information indicating the lapse of time after the previous circulation operation is obtained. Subsequently, based on the obtained information indicating the lapse of time, a preliminary circulation sequence is determined. Finally, the preliminary circulation sequence is performed based on the determined preliminary circulation sequence.

The present invention provides a liquid application device and an ink jet recording apparatus each capable of reducing deterioration in application quality due to an increase in the number of times of use of a roller, thereby improving durability. The present invention includes an application roller which applies liquid to an application medium, and a liquid retention member which retains the liquid in a liquid retention space formed by making the application roller be in contact with the retention member. With this structure, a pool of the liquid is formed, with rotation of the application roller, in an area upstream of a contact area, in a rotational direction, between the application member and the retention member at a side where a surface of the application member enters the contact area therebetween.
