Abstract: A recording apparatus includes a feeding roller and a power transmission mechanism for transmitting a driving force to the feeding roller. The power transmission mechanism includes a one-way compound gear mechanism that integrally includes a first one-way gear mechanism which is engaged with a first gear rotating forwardly or reversely by receiving the driving force from the driving source, rotates together with the first gear in a forward direction by receiving the driving force from the first gear at the time of the forward rotation and rotates idly with respect to the first gear at the time of the reverse rotation, and a second one-way gear mechanism which rotates idly with respect to the first gear at the time of the forward rotation and rotates with the first gear in a reverse direction by receiving the driving force from the first gear during the reverse rotation.

Abstract: A recording apparatus includes: a recording section that performs recording on a recording medium; a driving roller disposed in a transportation path; a plurality of driven rollers driven to rotate by abutting against the driving roller, and biased to the driving roller; and a frame defining positions of the driven rollers. A biasing member that biases driven rollers applies a biasing force including a first direction component that is in the transportation direction to the frame in a state of being mounted thereon. At least a part of the driven rollers are disposed by being deviated in the position thereof in a second direction opposite to the first direction in a state where the biasing member is not mounted thereon.

Abstract: A recording apparatus includes a power transmission unit configured to be in a power transmission state in which power of a motor is transmitted to a medium reception tray and a power non-transmission state in which the power of the motor is not transmitted to the medium reception tray, and a switching lever unit configured to switch between the power non-transmission state and the power transmission state. The switching lever unit rotates between a contact position and a non-contact position. When the switching lever unit is at the contact position, the switching lever unit switches between the power non-transmission state and the power transmission state by sliding in contact with the carriage as a carriage reciprocates.
