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: Disclosed is a filter circuit that includes means for monitoring currents flowing through positive and negative windings of a common-mode noise filter, and means for performing an adjustment based on the result of monitoring so as to equalize the current flowing positive and negative windings.

Abstract: An inverter apparatus wherein a sine wave AC voltage is produced from an output of a converter circuit which converts an input DC voltage into positive and negative sine half wave voltages of a voltage value corresponding to a width of a driving pulse. First and second switch circuits are provided for output lines of the positive and negative sine half wave voltages of the converter circuit. A plurality of pulses are generated within a half cycle of the AC output voltage of the converter circuit, and based on the pulse signal, when the positive sine half wave voltage is to be formed, the second switch circuit is put into an off state while the first switch circuit and the converter circuit are driven, but when the negative sine half wave voltage is to be formed, the first switch circuit is put into an off state while the second switch circuit and the converter circuit are driven. The width of each pulse of the pulse signal is modulated so that the AC output voltage may be a sine wave AC voltage.

Abstract: According to this invention, in a power supply circuit of a switching power supply apparatus, a circuit arrangement capable of adjusting the resistance values of a plurality of resistors in accordance with an input voltage condition is realized so that the switching power supply apparatus can be applied to a wide range of input voltages.
