A waste liquid collecting device is a device which is located to face a nozzle surface in which nozzles of a liquid ejecting portion are disposed, which includes a waste liquid receiving member to receive a liquid to be discharged from the nozzles, and which collects the liquid, and the waste liquid receiving member has dripping waste liquid receiving areas which are provided with through-holes and which receive the liquid to drip down after being discharged from the nozzles and staying on the nozzle surface and flushing receiving areas which are not provided with the through-holes and which receive the liquid to be ejected from the nozzles.

Waste liquid collecting device, liquid ejecting apparatus, and maintenance method of liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejector that ejects a liquid from a nozzle, a wiping mechanism that wipes a nozzle surface on which a plurality of nozzles is disposed with a wiping member, and a wiping-liquid supply mechanism that supplies a wiping liquid to the wiping member. The liquid ejecting apparatus is configured to perform wet-wiping of wiping the nozzle surface in a state where the wiping member has absorbed the wiping liquid and is configured to change a supply amount of the wiping liquid when the wiping member wipes the nozzle surface.

Liquid ejecting apparatus and maintenance method of liquid ejecting apparatus

A liquid ejecting head unit includes a liquid ejecting head having a nozzle forming portion in which a nozzle that ejects a liquid to a medium is formed, a shutter that has an opening portion exposing the nozzle and that is movable between a cover position in which a recessed portion including the nozzle is covered and an exposure position in which the nozzle is exposed, and a first communication portion that communicates with an inside of the recessed portion and that is capable of supplying a fluid into the recessed portion.

Liquid ejecting head unit, liquid ejecting apparatus, and maintenance method for liquid ejecting apparatus

A liquid ejecting apparatus includes a liquid ejecting head having nozzles for ejecting a liquid, and an attachment section to which a maintenance unit to be used for maintenance of the liquid ejecting head is to be detachably attached. If the maintenance unit having a maintenance mechanism for performing the maintenance by driving force transmitted from the attachment section is a first unit and the maintenance unit having no maintenance mechanism is a second unit, one of a plurality of the maintenance units including the first unit and the second unit and having different structure is interchangeably attached to the attachment section, and the attachment section includes an identification section configured to identify the structure of the attached maintenance unit and a driving-force transmission section configured to transmit the driving force to the attached first unit.

Liquid ejecting apparatus

A liquid ejecting apparatus performs first contact of an absorption member with a nozzle surface in which nozzles for liquid ejection are arranged, and performs second contact of the absorption member with the nozzle surface after the first contact. Pressure applied to, of the nozzle surface, a nozzle neighborhood area (a nozzle peripheral area) including the nozzles due to contact of the absorption member in the first contact is lower than pressure applied to the nozzle neighborhood area (a nozzle peripheral area) due to contact of the absorption member in the second contact.

Liquid ejecting apparatus and cleaning apparatus

Ratchets which regulate a rotation of either a reeling-out roller around which one end of a long wiping member which wipes ink attached to a recording head which ejects ink is wound, or a winding-up roller around which the other end of the wiping member is wound to which tension is applied due to a friction force which acts on the wiping member when performing wiping are provided.

Wiper cassette, wiper unit and liquid ejecting apparatus

Wiper unit and liquid ejecting apparatus

A sun gear which is rotationally driving according to power which is transmitted from a driving motor, a planetary gear which can be displaced in the circumferential direction of the sun gear in a state of being engaged with the sun gear, and a winding-up gear which transmits a rotational driving power to a winding-up roller are provided, and the planetary gear is released from an engagement with a rack gear unit, rotates the winding-up roller by being engaged with the winding-up gear, and winds up a wiping member after the planetary gear moves a wiper holder in the wiping direction by being engaged with the rack gear unit of the wiper holder.

An image reader is provided with a transparent member which is placed in an optical path from the surface of an original document bed on the side of a carriage to a condensing lens, whereby when the transparent member exists at a predetermined position, the condensing lens can be focused on a translucent original existing at a position above the position of a reflection original. When the transparent member is at a second predetermined position, the condensing lens can be focused on the reflection original. The condensing lens can be focused on more than one position simply by placing the transparent member in the optical path, so that the structure is simple and the manufacturing costs can be reduced.

Image reader and image reading method

There are provided an image reading apparatus and a focus adjusting method thereof in which focusing can be accurately conducted by a simple moving mechanism. A condenser lens and line sensor can be moved being integrated with each other. When output values obtained when a document on AF line is read by a line sensor are represented by LS , LS , LS , . . . , and when a broken line graph is considered on which the horizontal axis represents a reading position in the horizontal scanning direction and the vertical axis represents an intensity of an output signal, it is judged that the larger the total distance LM &plus;LM &plus; . . . of the broken lines is, the more accurately the image is in focus. A square root of the sum of the square of a distance between the adjacent reading positions and the square of a difference of intensities of the signals which have been read, is calculated, and it is judged that the larger the sum is, the more accurately the focus is adjusted.
