PROBLEM TO BE SOLVED: To suppress expansion of a displacement region of a displacement member such as a detection plate and a slider paper, even in a case where the size of a sheet that can be placed on a sheet supply tray increases.SOLUTION: In a case where a displacement amount of a first regulation guide 19 is a predetermined amount or less, a displacement member 27 is displaced in the same direction together with the first regulation guide 19. If the displacement amount of the first regulation guide 19 exceeds a predetermined amount, a connection member 29 is swingingly displaced with a protrusion part 41A as a center so that the displacement member 27 is displaced in the direction opposite to the first regulation guide 19. Thus, even if the displacement region of the first regulation guide 19 expands, it is suppressed that the displacement region of the displacement member 27 accordingly expands in proportional manner. Thus, even if the size of a sheet that can be placed on a sheet feeding tray 17 increases, expansion of displacement region of the displacement member 27 such as a detection plate and a slider is suppressed. |
