discharge roller 21 and pressure roller 23 of the discharge roller unit 20 when the leading edge of a check s 1 conveyed from the discharge roller unit 20 thus pushes against the paper shift lever 40 the paper shift lever 40 retracts in resistance to the force of the second spring 44 to a position allowing the check s 1 to advance passed the paper shift lever 40 when the trailing edge of the check s 1 is released by the discharge roller unit 20 and the check s 1 is thus pushed by the force of the second spring 44 into the check storage pocket 12 the distal end 24 d of the first arm 24 b of the first pressure lever 24 which is pivotally urged by the first spring 27 also presses against the back receiving part 32 of the first arm 30 a of the second pressure lever 30 the force of first spring 27 is thus transferred through the first pressure lever 24 to the second pressure lever 30 and this force causes the second pressure lever 30 to rotate to the closed position the directions in which the first pressure lever 24 second pressure lever 30.
