The pouch has: a liquid storing chamber configured to store the liquid therein and communicating with the channel of the spout, a sealing part configured to seal surrounding of the liquid storing chamber, and a liquid-non-storing chamber which is positioned to be separated with respect to the spout by the liquid storing chamber and the sealing part, and in which the liquid is not stored.

Liquid pack and method of producing the same

A printing device includes a head including a nozzle configured to ejects ink, a platen including a support surface configured to support a printing medium to which a pretreatment liquid is applied, the pretreatment liquid containing a volatile component that reacts with the ink, and a humidified air supply port configured to supply humidified air to the support surface of the platen that supports the printing medium, the humidified air supply port being provided around the platen in which the support surface of the platen is disposed at a printing position facing the nozzle.

Printing device

A platen conveyance device includes a first conveyance path, a platen supporter, a second conveyance path, and a positioner. The first conveyance path is configured to convey a platen to a pretreatment device. The platen supporter is configured to support the platen conveyed by the first conveyance path. The second conveyance path is provided with the platen supporter. The second conveyance path is configured to convey the platen supporter to a printer. The positioner is configured to position the platen supported by the platen supporter at a prescribed printing position in a first direction in a horizontal direction.

Platen conveyance device

A platen conveyance device includes a first conveyance path, a platen supporter, a second conveyance path, and a positioner. The first conveyance path is configured to convey a platen to a pretreatment device. The platen supporter is configured to support the platen conveyed by the first conveyance path. The second conveyance path is provided with the platen supporter. The second conveyance path is configured to convey the platen supporter to a printer. The positioner is configured to position the platen supported by the platen supporter at a prescribed printing position in a horizontal direction.

A printer is provided with a platen support member, a platen, and a positioning portion. The platen support member supports the platen. The platen includes a rear engaging portion. The positioning portion includes a rear roller. The rear roller is provided at the platen support member, and can move in the front-rear direction with respect to the platen support member. The rear roller engages with the rear engaging portion in a state in which the platen is supported by the platen support member. The positioning portion positions the platen at a prescribed printing position in the front-rear direction, by the rear roller moving forward in a state in which the rear engaging portion is engaged with the rear roller.

Printer having a mechanism for positioning a platen

A platen conveyance device includes a platen, a first platen support portion, a first conveyance path, a second platen support portion, a second conveyance path, and a platen moving portion. The platen includes a neckline guide portion. The first platen support portion supports the platen. The first conveyance path movably guides the first platen support portion in a first direction. The second platen support portion supports the platen. The second conveyance path movably guides the second platen support portion in the first direction. The platen moving portion moves the platen, which is supported by one of the first platen support portion and the second platen support portion with the neckline guide portion positioned on a first side in the first direction, to the other of the first platen support portion and the second platen support portion with the neckline guide portion positioned on the first side.

Platen conveyance device and platen moving device

Ink cartridge

A cartridge case includes a case, a spout support portion, a mount portion, a roll-up member, and a lock member. The case includes a first face extending in a first direction. The spout support portion is configured to support a spout provided in a liquid container containing an inkjet liquid. An end portion on a first direction side of an elastic member is mountable in the mount portion. The elastic member generates an energizing force in the first direction. The roll-up member is configured to roll up the liquid container by being moved in the first direction by the energizing force of the elastic member. The lock member is configured to lock movement, in the first direction, of the roll-up member. The lock member is configured to release lock of the roll-up member, based on consumption of the inkjet liquid contained in the liquid container.

Cartridge case

A cartridge case includes a case, a spout support portion, a mount portion, a roll-up member, and a resistance portion. The case includes a first face extending in a first direction. The spout support portion is configured to support a spout provided in a liquid container containing an inkjet liquid. An end portion on a first direction side of an elastic member is mountable in the mount portion. The elastic member generates an energizing force in the first direction. The roll-up member is configured to roll up the liquid container by being moved in the first direction by the energizing force of the elastic member. The resistance portion is configured to generate resistance to movement of the roll-up member in the first direction at the end portion side of the case. The resistance portion is configured to increase the resistance as the roll-up member moves in the first direction.

A cartridge case includes a case body, a shaft portion, a first support portion, a second support portion, and a switching member. The shaft portion includes a shaft support portion and engages with an end portion of an elastic member. The shaft portion is configured to be moved by an energizing force of the elastic member. The switching member is configured to switch a position of the second support portion between an operating position and a released position. The operating position is a position where the second support portion and the first support portion hold the shaft support portion between the second support portion and the first support portion. The released position is a position where the second support portion has moved away from the shaft support portion.

A mount portion mounts a container containing liquid. A fluid passages connects the mount portion to a head portion provided to inject liquid. A reservoir portion reserves liquid and is provided on the fluid passage. An open-close valve is provided on a connection path which is a part of the fluid passage and connects the mount portion to the reservoir portion. The control unit controls opening and closing of the open-close valves such that a first valve open time period for the open-close valve provided on a first connection path is shorter than a second valve open time period for the open-close valve provided on a second connection path. The pressure of the liquid that flows in the reservoir portion from the first connection path is higher than the pressure of the liquid that flows in the reservoir portion from the second connection path.

Print device

A print device includes mount portions, flow passages and reservoir portions. The mount portion mounts a container containing liquid. The flow passage connects the mount portion to a head portion having a nozzle face. The reservoir portion provided on the flow passage reserves liquid and is located such that a distance from the nozzle face in the up-down direction is within a prescribed range. A first and second reservoir portions are aligned in a first direction in the horizontal direction. The first reservoir portion is inclined such that a part of the first reservoir portion is situated to progress upward towards the first direction. The second reservoir portion is inclined such that a part of the second reservoir portion is situated to progress upward towards the first direction. The first and second reservoir portions are at least partially overlapped each other in the up-down direction.
