Abstract
A sheet supply device includes a medium loading part that includes a medium loading surface on which medium is loaded; and a medium supply part that is arranged facing the medium lading surface, and sandwiches the medium with the medium loading part applying a pressure to the medium, and sends the medium loaded in the medium loading part in a predetermined carrying direction. The medium loading part includes a first friction member arranged in a position facing the medium supply part so that the first friction member contacts the medium supply part when there is no medium on the medium loading part, and a second friction member arranged on an upstream side of the first friction member in the carrying direction, and a friction coefficient (μd) between the second friction member and the medium is larger than a friction coefficient (μc) between the first friction member and the medium.
