Abstract: A liquid ejecting apparatus includes a liquid ejection head to eject liquid, a recovery unit, a housing, a discharge unit, a casing including the discharge unit and the housing, and a liquid receptacle. The recovery unit maintains liquid ejecting performance of the liquid ejection head. The housing houses a container that accommodates liquid received by the recovery unit. The discharge unit discharges the liquid received by the recovery unit to the container. The liquid receptacle is disposed below the discharge unit in a direction of gravity in the casing and includes a first groove extending in a first direction crossing the direction of gravity and a second groove extending in a second direction crossing the direction of gravity and the first direction.

Abstract: A printing apparatus includes a liquid tank unit, a printing head, and a supply tube unit. The liquid tank unit includes first and second liquid tanks that store liquid and are arranged in parallel to each other. The printing head ejects liquid from the first and second tanks while moving in a main scanning direction. The supply tube unit includes a first supply tube connecting the first liquid tank to the printing head and includes a second supply tube coupled in parallel to the first supply tube and connecting the second liquid tank to the printing head. The second supply tube transitions from a connected tube state in which the second and first supply tubes are coupled in parallel to a single tube state by being separated from the first supply tube, passes across the first supply tube, and is connected to a connection port of the second liquid tank.

Abstract: Disclosed is a recording apparatus including a tank configured to store liquid to be supplied to a recording head that ejects the liquid, the tank including an inlet port for liquid injection; a cap unit including a shaft portion and a cap configured to turn about the shaft portion between a first position at which the cap caps the inlet port and a second position at which the cap does not cap the inlet port, the shaft portion being provided to a housing that encloses the tank; and a biasing unit configured to bias the cap unit in a direction to move the cap apart from the inlet port, wherein the cap unit does not move at the second position while being biased by the biasing unit.

Abstract: A liquid storage container includes a storage portion configured to store liquid, an opening portion provided on a first surface and configured to allow injection of the liquid into the storage portion, a receiving portion consisting of the first surface and a wall disposed around the opening portion on the first surface, and a liquid holding unit configured to hold the liquid guided by a guiding portion from the liquid receiving portion to outside of the liquid receiving portion. The liquid holding unit includes a second surface different from the first surface of the liquid storage container and a flexible member.

Abstract: A printing apparatus includes a support member configured to support a printhead that performs printing by discharging ink to a print medium, a connecting member including a connecting portion connected to an ink introduction portion of the printhead and through which the ink introduction portion communicates with an ink supply passage via the connecting portion, a rotation member configured to hold the connecting member such that a posture of the connecting member is changeable, and configured to be supported by the support member to be rotatable between a connecting position at which the ink introduction portion and the connecting portion are connected and a connection releasing position at which the ink introduction portion and the connecting portion are not connected, and a biasing portion configured to bias the connecting member to a first posture with respect to the rotation member.

Abstract: In order to carry out a display reset operation, a segment driver and a common driver are driven to operate as below during a display data reading period in which voltages to be applied to a liquid crystal display panel are nonuniform between lines. First, a shift register and a level shifter which are provided in the segment driver and a shift register and a level shifter which are provided in the common driver are driven to operate as usual, whereas a display control signal supplied from a controller causes output circuits to stop carrying out their respective output operations. In at least one embodiment, during a period in which a writing operation is carried out with respect to the liquid crystal display panel so as to carry out the display reset operation, the display control signal supplied from the controller allows the output circuits to carry out the respective output operations. This allows a memory (e.g.

Abstract: A liquid crystal display device includes a liquid crystal panel having a plurality of scanning electrodes including first and second scanning electrodes, a plurality of signal electrodes including a first signal electrode, and a liquid crystal layer. A display is generated based on display data including first and second display data. The liquid crystal display device further includes a scanning electrode driver which outputs a scanning voltage to the first scanning electrode in a first scanning period and outputs a scanning voltage to the second scanning electrode in a second scanning period following the first scanning period. A signal electrode driver outputs a first voltage corresponding to the first display data to the first signal electrode in the first scanning period and outputs a second voltage corresponding to the second display data to the first signal electrode in the second scanning period.

Abstract: A driving method for a liquid crystal display is provided with the steps of (a) applying a row select voltage to each of the row electrodes simultaneously, the row select voltage corresponding to an element of an orthogonal matrix and being either +1 or -1 ; (b) conducting an exclusive-or operation with respect to each element of a row select vector and a display vector, the row select vector indicating the row select voltages by vector notation and the display vector indicating a display data by the vector notation, and conducting a summation of each exclusive-or operation; (c) applying to the column electrode a voltage of a level which varies depending on the summation so as to simultaneously drive the plurality of rows; and (d) in a case where all the display data correspond to ON display or OFF display in the step (c), assigning the row select voltage, applied to either the selected row electrode having the lowest select voltage among driving voltages within one frame period for the ON display or the sele
