Abstract:
1. A sheet supply device comprising: a medium storage portion for retaining a medium; a medium feeding portion for feeding the medium from the medium storage portion; a first separation unit for contacting with the medium at a first contact point; a transportation guide arranged to face the first separation unit with a specific distance in between so that the medium passes through between the transportation guide and the first separation unit; and a second separation unit disposed on a downstream side of the first separation unit in a transportation direction of the medium for contacting with the medium at a second contact point after the medium passes through the first contact point of the first separation unit, said second separation unit being disposed substantially at a center in a width direction, said first separation unit being disposed outside the second separation unit, wherein said first separation unit includes a right side separation unit disposed on a right side of the second separation unit in the width direction and a left side separation unit disposed on a left side of the second separation unit in the width direction so that the second separation unit is not overlapped with the right side separation unit and the left side separation unit along the transportation direction, said transportation guide includes a right side guide facing the right side separation unit and a left side guide facing the left side separation unit, said right side separation unit and said left side separation unit are arranged to contact with a lower surface of the medium, wherein each of said right side guide and said left side guide includes a first rib facing the first separation unit and a second rib not facing the first separation unit, said right side guide and said left side guide are arranged to contact with an upper surface of the medium, said right side guide and said left side guide are arranged to extend from an upstream side of the first separation unit to a downstream side of the second separation unit in the transportation direction, said first separation unit further includes a separation member for separating the medium and a friction member for applying a load to the medium, said second separation unit includes a pair of rollers for separating the medium, and said friction member is arranged in an inclined state crossing from below to above an imaginary line between the second contact point and a third contact point where the medium feeding portion contacts with the medium.
