The medium transporting device is arranged so as to face the feeder for feeding the medium in the transporting direction and the surface of the medium transported in the transporting direction, and detects the motion of the medium in the two-dimensional coordinate system including the first axis and the second axis. The two-dimensional sensor is provided in a state in which the first axis and the second axis are inclined with respect to the transporting direction.

Medium transporting device, image reading apparatus, and transporting control method

A control portion performs a predetermined detection process on a first image from a first reading portion and a second image from a second reading portion. When the detection process on the each image is successful, the control portion performs, based on a value of an image processing variable specified from a detection result, predetermined image processing on the each image, When the detection process on the image of one side fails, a value of an image processing variable for the image of one side is specified based on a value of an image processing variable specified from the detection result for the image of the other side for which detection is successful. Based on the specified value of the image processing variable, image processing is performed on the image of one side.

Image reading apparatus, image reading system, image reading method, and non-transitory computer-readable storage medium storing program

A medium transporting apparatus includes a feeding roller that rotates to transport a medium along a transportation path, an electrode installed downstream of the feeding roller on the transportation path and having conductivity, and an electric charge detecting circuit that outputs a signal having a magnitude corresponding to an amount of an electric charge, which moves from the medium to the electrode after the medium being transported along the transportation path comes into contact with the electrode.

Medium transporting apparatus, image reading apparatus, and method for detecting medium by medium transporting apparatus

There is provided a medium transporting device including: a medium placement section on which a medium is placed, a feeding roller feeding a medium from the medium placement section, a motion detection sensor detects a motion of a medium, and a controller that stops feeding of a medium based on a detection value received from the motion detection sensor, in which the motion detection sensor is a two-dimensional sensor including a light emitting section and a light receiving section and detecting a motion of a medium, the medium placement section is provided with a placement detector that acquires information relating to a presence/absence of a medium on the medium placement section, and the controller sets a state of the light emitting section to a non-light emitting state when detection information of the placement detector indicates that a medium is absent on the medium placement section.

A medium transport apparatus includes a feeding section configured to nip a medium and feed the medium in a transport direction, a sensor disposed to face a side of the medium being transported in the transport direction, the sensor being configured to detect motion of the medium, and a control unit configured to stop the transport of the medium based on a detection value received from the sensor, in which during a period including a time at which a leading edge of the medium is nipped by the feeding section, the control unit continues transporting the medium irrespective of the detection value from the sensor.

Medium transport apparatus, image reading apparatus, and transport control method

An image reading apparatus is provided with a reader which reads a document, a transport roller which is provided on an upstream side of the reader in a document transport path in which the document is transported and transports the document to a reading position of the reader, and a controller which receives reading data of the reader and controls the transport roller, in which the controller receives the reading data from the reader to acquire a form of the document, and selects whether or not to stop driving of the transport roller based on the form.

Image reading apparatus

Managing commands that have not been executed is simplified while maintaining a state in which real-time commands can be executed. A printerhas a write control unitA that writes received commands to a receive buffer, a command execution unitB that executes the written commands, and a real-time command execution unitC that executes written commands that are real-time commands. The printerenters a full-buffer mode as needed by the capacity of available storage space in the receive buffer, and when in the full-buffer mode the write control unitA cyclically writes commands to an auxiliary space created in the receive buffer, and the real-time command execution unitC reads and executes real-time commands from the auxiliary space.

Electronic device, control method for an electronic device, and recording medium

The invention provides an electronic device having a structure operable by the power of a battery pack. The electronic device includes: an authenticating section that authenticates a battery pack connected so as to supply power to determine whether the battery pack is a genuine product; a user interface; and a controller for controlling the electronic device. The controller tries authentication of the battery pack connected so as to supply power with the authentication section. When the battery pack has been authenticated, the discharging of the battery pack is enabled. When the battery pack has not been authenticated, the controller requests the user to input recognition whether the battery pack is a genuine product through the user interface, and changes the control for the battery pack between when the user inputs, in response to the request, the recognition that the battery pack is a genuine product and when the user inputs the recognition that the battery pack is not a genuine product.

Electronic device, method for controlling the same, and program for the same

A liquid ejection apparatus has a liquid cartridge including a liquid container that has a flexible portion and stores liquid therein and a pressure chamber for applying pressure to the flexible portion of the liquid container; a liquid ejection head for ejecting liquid; a liquid flow path for guiding liquid from the liquid container to the liquid ejection head; a pressure pump for generating pressurized air; and an air flow path for guiding the pressurized air to the pressure chamber. The pressure pump includes an air chamber that communicates with the air flow path and a pressing member for pressing the air chamber so as to decrease the capacity of the air chamber. The capacity of the air chamber is decreased by the pressing member so as to increase the pressure in the air chamber to an upper limit value of a liquid supply pressure range where a prescribed liquid ejection characteristic is obtained, before a liquid ejecting operation is performed on an ejection target member. A continuous liquid ejecting operation is performed on an ejection target member having a maximum size for the liquid ejection apparatus in a state that the capacity of the air chamber is fixed.
