Abstract: A medium feeding apparatus includes a feed roller that feeds media. A separation roller nips the media together with the feed roller to separate it and is rotated in a first direction to feed the media. A motor applies driving torque to the separation roller in a second direction opposite to the first direction. A torque limiter, when rotation torque applied to the separation roller in the first direction exceeds a preset upper torque limit, causes the separation roller to rotate at idle in the first direction independently of the driving torque. During feeding operations, including feeding of first and second media, a controller that controls the motor provides a break period in which the motor is not driven. The break period contains the timing when a rear edge of the first medium leaves a nip position between the feeding and separation rollers.

Abstract: A technique of enhancing attachment of a liquid supply unit to a liquid ejection device is provided. A first ink cartridge 100a and a second ink cartridge 100b are attached to a carriage 27 of a printing device 10 via a holder structure 200. Each of the first and the second ink cartridges 100a and 100b includes a circuit substrate 130 having a plurality of terminals 151 to 159 which are electrically connected with a device-side terminal assembly 250 provided on the holder structure 200. Each of the first and the second ink cartridges 100a and 100b also includes a main engagement part 120 configured to engage with a lever member 230 of the holder structure 200 as an engaged part, such as to limit motion of the circuit substrate 130 away from the holder structure 200. The circuit substrate 130 includes a first terminal 151 and a second terminal 152 located on respective ends in an array direction of the terminals. The main engagement part 120 has a width greater than an interval between contact portions CP of the first and the second terminals 151 and 152 in the array direction of the terminals.

Abstract: A control unit of a medium feeding apparatus is configured to execute a fault detection process to determine that there is a feeding fault when a movement of a subsequent medium in a feeding direction is detected based on detection information of a movement detection unit within a fault detection period that is set after a trailing edge of a preceding medium is detected based on the detection information of the movement detection unit and before feeding of the subsequent medium is started, and the fault detection period set when a size of the medium in a width direction intersecting the feeding direction is a first size is shorter than the fault detection period set when the size of the medium in the width direction is a second size larger than the first size.
