Abstract: In a liquid cartridge, a liquid storing section defines a liquid storing chamber storing liquid, and a channel section defines a channel in fluid communication with the liquid storing chamber. A field forming section forms a field that changes depending on a position of a movable member that is movable in the channel. A power-source potential is inputted to a power-source terminal, and a ground potential is inputted to a ground terminal. A sensor is electrically connected with the power-source terminal and the ground terminal, and generates a potential based on the position of the movable member by being disposed in the field formed by the field forming section. An output terminal outputs the potential generated by the sensor. The sensor generates the potential higher than a ground potential regardless of the position of the movable member.

Abstract: A liquid cartridge includes a liquid reservoir, a liquid flow path that selectively places the reservoir in fluid communication with an exterior of the cartridge, a sensor that outputs a signal relative to a position of an object in the liquid flow path, a storage that stores data therein, and a plurality of terminals. The plurality of terminals includes a sensor terminal connected to the sensor, a power terminal connected to at least one of the sensor and the storage, and that receives power, and a data terminal connected to the storage. A distance between a first portion of the power terminal and at least a portion of the data terminal is greater than a distance between a second portion of the power terminal and at least a portion of the sensor terminal.

Abstract: Disclosed is a recording apparatus including a recording portion which records an image on a recording medium, a feeding mechanism which feeds the medium along a feed path extending from a recording-medium supply position to a recording-medium ejection position via a recording point where the recording portion performs the recording of the image, a reading portion which reads the image recorded on the medium fed along the feed path, and a position controller which controls a position of at least one of the medium and the reading portion such that the medium as located at a reading point for the reading portion in the feed path is selectively placed in one of a first position allowing the reading portion to read the image recorded on the recording medium and a second position at which the recording medium is away from the reading portion farther than when at the first position.

Abstract: A signal processing apparatus is provided which includes a signal processing circuit for processing a weak signal susceptible to noises, an electronic component which is selectively energized and de-energized, and a controller for controlling the operation of the electronic component. The controller first determines initiation and termination of the weak signal processing. Upon determination of the initiation of the weak signal processing, the controller causes the electronic component to be continuously energized. Upon determination of the termination of the weak signal processing, the controller causes the electronic component to be intermittently energized.
