A printing material supply system includes a printing device and a cartridge. The printing device has a cartridge mounting structure. The cartridge is removably attached to the cartridge mounting structure. The cartridge mounting structure has a device-side terminal, a lever, a first device-side locking element and a second device-side locking element. The device-side terminal is configured to contact with a cartridge-side terminal. The first device-side locking element is configured as part of the lever. The second device-side locking element is configured to engage with a second locking surface of a second cartridge-side locking element. The cartridge-side terminal has a cartridge-side contact portion configured to be in contact with the device-side terminal. The cartridge-side contact portion is provided on the negative Z-axis side of the second locking surface.

Cartridge and printing material supply system

A recording apparatus includes a carriage, a transport drive roller, and a plurality of gears. The carriage includes a recording head configured to record onto a medium. The carriage is configured to move in a movement region in a first direction and a second direction that is an opposite direction thereto. The transport drive roller is configured to transport the medium to a recording region in which the recording head performs recording. The plurality of gears are configured to transmit power of a motor to the transport drive roller. When the carriage is positioned at an end of the movement region in the second direction, at least a portion of one of the plurality of gears overlaps the carriage when viewed along a vertical direction that is parallel to a direction of gravity and overlaps the recording head when viewed along an axial direction of the transport drive roller.

Recording apparatus

A printing material supply systemincludes a printerequipped with a holderand cartridgesthat are detachably attached to the holder. The holderhas a first apparatus-side locking elementand a lever. The first apparatus-side locking elementis formed as part of the lever. The cartridgehas a first cartridge-side locking elementthat includes a first locking surfaceto engage with the first apparatus-side locking element. The first cartridge-side locking elementhas an extended surfacethat prevents a negative Z-axis endof the leverfrom running on the first locking surface

A liquid supply system adapted to be mounted in a carriage unit having a first liquid introduction portion and a second liquid introduction portion is proposed. The liquid supply system comprises two liquid supply units each having liquid supply portion adapted to liquid to the first and second liquid introduction portions, respectively. The two liquid supply units are adapted to be attached to and detached from the carriage unit. The liquid supply system further comprises a holder unit adapted to be attached to and detached from the carriage unit and adapted to fix the two liquid supply units to the carriage unit. The two liquid supply units are located between the holder unit and the carriage unit.

Liquid supply system

A recording device includes a liquid ejection head, a support unit that support a paper sheet, a transportation path along which the paper sheet is reversed and transported, and a transportation roller that transports the paper sheet, wherein a liquid absorbent is provided downstream in the transportation direction of the paper sheet relative to the transportation roller, and liquid absorbents are provided upstream in the transportation direction of the paper sheet relative to the transportation roller, and second liquid absorbent is provided between the liquid absorbent and the liquid absorbent.

Recording device

A recording apparatus includes a carriage that includes a recording head performing recording on a recording medium, and an edge detection unit detecting an edge of the recording medium, and is movable in a predetermined direction, in which, in a state in which the carriage is positioned at a predetermined position, the edge detection unit is positioned in a passing region of the recording medium in the movement direction of the carriage, and the predetermined position is a home position of the carriage.

A technique of enhancing attachment of a liquid supply unit to a liquid ejection device is provided. A holder structureis provided as a mounting mechanism configured to cause a first ink cartridgeand a second ink cartridgeto be attachable to and detachable from a carriageof a printing device. The holder structurehas a lever memberprovided as a rotation mechanism to be rotated and thereby lock the first and the second ink cartridgesand. The lever memberincludes a first leg section, a second leg sectionformed away from the first leg sectionand a bridging sectionformed between the first and the second leg sectionsandto engage with a main engagement partof each of the ink cartridgesand

A recording apparatus includes a recording head, a carriage having an opening on which the recording head is mounted in a state that the liquid ejection surface of the recording head faces the opening, the carriage being configured to reciprocate, a ground member that is mounted on the carriage so as to ground the recording head, and a sensor unit that is mounted on the carriage so as to perform sensing by using reciprocation of the carriage and has a ground mechanism which is connected to the ground member, wherein the ground member is disposed at a position in contact with the recording head mounted on the opening.

A cartridge comprises an ink supply structure, a terminal bearing structure, and a first restriction portion. The terminal bearing structure has terminals arranged in a terminal plane which is neither parallel nor perpendicular to a plane defined by a mounting direction leading edge of the ink supply structure, so that the contact portions of the terminals receive a force in a direction opposite from the mounting direction. An engagement portion of the first restriction portion is provided at a position adjacent to the terminal bearing structure.

A printing apparatus adapted to have a cartridge detachably mounted thereon includes a cartridge mounting structure, a printing material supply tube, a plurality of apparatus-side terminals and a lever used for attachment and detachment of the cartridge to and from the printing apparatus. The lever has an operating member, a first apparatus-side locking portion and an axis of rotation. When an external force is applied to the operating member of the lever from the +X-axis direction to the &#x2212;X-axis direction, the lever moves the first apparatus-side locking portion about the axis of rotation from a specified locking position toward the +X-axis direction and disengages the first apparatus-side locking portion from a first cartridge-side restriction portion, so as to eliminate the restriction of motion of the cartridge. This ensures stable electrical connection between cartridge-side terminals and apparatus-side terminals.

A cartridge comprises an ink supply structure, a terminal bearing structure, and a first restriction portion. The terminal bearing structure has terminals arranged in a terminal plane which is neither parallel nor perpendicular to a plane defined by a mounting direction leading edge of the ink supply structure, so that the contact portions of the terminals receive a force in a direction opposite (RD) from the mounting direction. An engagement portion of the first restriction portion is provided at a position adjacent to the terminal bearing structure.

A cartridge mounting mechanism includes a chamber that accommodates therein a cartridge introduced through a cartridge inlet formed as an opening directed upward, a biasing mechanism that biases the cartridge set in the chamber in an upward direction corresponding to a removal direction of the cartridge, and a holding mechanism configured to be engaged with the cartridge so as to restrict, against a biasing force of the biasing mechanism, the cartridge from moving in the removal direction when the cartridge is set in the chamber, and disengaged from the cartridge to release the cartridge from the restriction against the biasing force, upon being subjected to an external operating force.
