A nail polish application apparatus, comprising a mounting element comprising a capsule compartment adapted to receive one or more capsules containing a nail polish fluid wherein the mounting element is moveable by actuator(s) in longitudinal axis crossing a nail polish applying space and in lateral axis perpendicular to the longitudinal axis and is rotatable by the actuator(s) around the longitudinal axis, a pressure applying element adapted to apply pressure on a body portion of the capsule(s) installed in the capsule compartment wherein the body portion defines a reservoir containing a nail polish fluid, the pressure builds an internal pressure in the reservoir forcing extrusion of the nail polish fluid to a nail polish applying element integrated with the capsule(s), sensor(s) adapted to generate sensory data depicting the nail polish applying space and a control unit adapted to operate the actuator(s) and the pressure according to analysis of the sensory data.

A control unit of an image reading apparatus acquires, at an upstream position in a medium transportation direction of an abnormality determination area set for a leading-edge area of a medium, a distance WL from a center position in a medium width direction intersecting with the medium transportation direction to one edge in the medium width direction and a distance WR from the center position to the other edge in the medium width direction, and compares a value R that is a ratio between the distance WL and the distance WR or a difference therebetween with a threshold R0 determined in advance.

An image processing apparatus includes: an automatic document feeder; a document placement table; a document detector provided on at least one of the automatic document feeder and the document placement table, the document detector being configured to detect a document; and circuitry to cause a display to display one of a first screen that receives an input for selecting an orientation of a document placed on the automatic document feeder and a second screen that receives an input for selecting the orientation of the document placed on the document placement table, based on a detection result of the document detector.

In a medium conveying device, a projector projects light, a projection light amount of the light changes, at every fixed time, to a first projection light amount and a second projection light amount less than the first projection light amount, a receiver receives the light projected from the projector, a processor determines, at fixed sampling timings, whether a reception light amount of the receiver is at a first reception light level or a second reception light level smaller than the first reception light level, determines, when the reception light amount alternately changes to the first reception light level and the second reception light level, that a medium is not present on a conveying path, and determines, when the reception light amount is fixed to either the first reception light level or the second reception light level, that the medium is present on the conveying path.

An image captured by a camera can be processed by a scanning application to identify one or more regions within the image that are suitable for scanning. One or more of these regions can be selected for scanning automatically based on user-input such as a fingertip touch to a particular portion of the display screen. Users may also select multiple regions and submit multiple quadrangular regions for scanning to PDF from a single image.

An image reading apparatus includes: a reading unit, which is configured to read an original placed on an original table in a main scanning direction by irradiating the original with light; and a sub-scanning size detector, which is configured to detect presence or absence of the original on the original table by radiating invisible rays. When the platen cover forms an angle of equal to or smaller than a first angle with respect to the original table, the image reading apparatus determines a size of the original in a sub-scanning direction in accordance with a detection result acquired from the sub-scanning size detector. When the platen cover forms an angle equal to or smaller than a second angle, which is smaller than the first angle, with respect to the original table, the image reading apparatus determines a size of the original in the main scanning direction.

A document reading device includes an image reading part, a document conveying part, an operation display part, an overlap detecting part and a controlling part. The overlap detecting part detects overlap of a document conveyed to the image reading part. When the overlap detecting part detects the overlap, if an overlap image corresponding to the overlap in the image data obtained by the image reading part matches with a predetermined preservation image, the controlling part decides that the overlap is not double feed to continue the scanning operation. If the overlap image does not match with the predetermined preservation image, the controlling part decides that the overlap is the double feed, stops the scanning operation, and, if user judgement that the overlap is not the double feed is inputted in accordance with operation of the operation display part, stores the preservation image on the basis of the overlap image.

A medium transporting apparatus includes a first medium transport path in which a transport roller pair is provided, a second medium transport path for feeding a medium fed downstream in a medium transport direction from the transport roller pair to an upstream position of the transport roller pair in the first medium transport path, and a medium detection unit for detecting passage of a medium in the first medium transport path, in which a position at which the medium detection unit detects a medium is switched between a transport direction upstream position and a transport direction downstream position of the transport roller pair according to whether or not a medium is transported on the second medium transport path.

Sheet feeding has been started after storing image data for one page of a document. A control method for a printing apparatus includes feeding a sheet from a sheet holding unit by a feeding unit, reading an image of a document by a reading unit, storing image data of the document read by the reading unit in a storing unit, and reading out, before image data for one page of the document is stored in the storing unit, the image data of the document from the storing unit and printing, by a printing unit, the image based on the read image data to the sheet fed from the sheet holding unit by the feeding unit, in which the feeding unit is able to start to feed the sheet from the sheet holding unit before the image data for the one page of the document is stored in the storing unit.

A medium feeding device includes: a medium mounting section that a medium is mounted; a feeding unit that feeds the medium in a feeding direction; a separation unit that separates the medium with the feeding unit; an operation detection unit that is disposed at a position facing a surface of the medium in the medium mounting section and detects a movement of the medium in the feeding direction; an interval forming unit that forms an interval in the feeding direction between a trailing end of a first medium which is the lowest medium fed among media mounted on the medium mounting section and a trailing end of a second medium which is bound with the first medium and stacked on the first medium; and a control unit that stops feeding of the medium based on a detection interval by a detection value of the operation detection unit.
