A liquid discharging apparatus includes an accommodating container accommodating conductive liquid, a rod-shaped first electrode accommodated in the accommodating container, a rod-shaped second electrode accommodated in the accommodating container, a detection portion that is electrically coupled to the first electrode and the second electrode and that detects a remaining amount of the liquid accommodated in the accommodating container in response to an electric signal from at least one of the first electrode and the second electrode, and a liquid discharging head discharging the liquid that is supplied from the accommodating container, in which the first electrode includes a first part having an outer periphery with a first length, and a second part having an outer periphery with a second length that is shorter than the first length.

Liquid discharging apparatus and liquid accommodating device

A liquid accommodating device includes an accommodating container accommodating conductive liquid, a first electrode accommodated in the accommodating container, a second electrode accommodated in the accommodating container, and a detection portion that is electrically coupled to the first electrode and the second electrode and that detects a remaining amount of the liquid accommodated in the accommodating container in response to an electric signal from at least one of the first electrode and the second electrode, in which the first electrode includes a first part where a first conduction portion formed with a conductive member is exposed, a second part where the first conduction portion is exposed, and a first insulation part that is provided between the first part and the second part and in which the first conduction portion is covered with an insulation member.

A liquid discharging apparatus includes an accommodating container accommodating conductive liquid, a first electrode accommodated in the accommodating container, a second electrode accommodated in the accommodating container, a detection portion that is electrically coupled to the first electrode and the second electrode and that detects a remaining amount of the liquid accommodated in the accommodating container in response to an electric signal from at least one of the first electrode and the second electrode, and a liquid discharging head discharging the liquid that is supplied from the accommodating container, in which the first electrode includes a first part where a distance between the first part and the second electrode is a first distance, and a second part where a distance between the second part and the second electrode is a second distance that is longer than the first distance.

A printing apparatus includes a medium accommodation portion that accommodates a medium, a medium discharge port for discharging the medium, a medium transport section that transports the medium, an ejection head that ejects a liquid to the medium to form an image, and an image detection section that detects the image. The printing apparatus has a first mode and a second mode, the first mode being a mode in which the medium transport section transports the medium in a direction from the medium accommodation portion toward the medium discharge port, and the ejection head ejects the liquid to the medium, and the second mode being a mode in which the medium transport section transports the medium in a direction from the medium discharge port toward the medium accommodation portion, and the image detection section detects image information of the image formed on the medium.

Printing apparatus

A printing apparatus includes a medium accommodation portion that accommodates a medium, a medium discharge port for discharging the medium to an outside of the printing apparatus, a medium transport section that transports the medium along a transport path from the medium accommodation portion toward the medium discharge port, an ejection head that ejects a liquid to the medium to form an image on the medium, a heat generation section that dries the liquid ejected to the medium by heat, and an image detection section that detects the image formed on the medium. The ejection head, the heat generation section, and the image detection section are provided along the transport path. The ejection head is located between the heat generation section and the image detection section in a direction along the transport path.
