Claim:
1. A medium feeding device, comprising: a device body; a roller that is provided at the device body and that feeds media; a tray that is provided in a manner capable of being pulled out from and inserted into the device body and that faces the roller in a state in which the tray is inserted into the device body; a detection part that detects presence of the media loaded in the tray; and a bias part that is provided at the detection part, wherein the detection part comprises: the lever body and the body holding part are rotatable about a common rotational axis, the bias part biases the lever body in a first direction in which the first engagement part of the lever body engages with the second engagement part of the body holding part, when the tray is inserted into the device body and when the media are loaded in the tray so that the media are feedable by the roller, the lever body and the body holding part are rotatable together about the common rotational axis while the first engagement part of the lever body and the second engagement part of the body holding part are engaged with each other by the bias part, and the light-blocking part is in a position away from the sensor part such that the sensor part does not detect the light blocking part, and when a pressing force is applied to the lever body in a second direction that is opposite from the first direction, the engagement between the first engagement part of the lever body and the second engagement part of the body holding part is released against a bias force of the bias part, and the lever body rotates about the common rotational axis in the second direction while the rotation of the body holding part is restricted and the light blocking part blocks the sensor part such that the sensor part detects the light blocking part.
