The abutment member 40 specifically includes two abutment rods 41, each of the two abutment rods 41 extends along the Z direction, and both of the two abutment rods 41 face opposite to the surface of the substrate 10 to form an abutment surface 42, the two abutment rods 41 are disposed at a certain distance from each other in the X direction, and the bottoms of the two abutment rods 41 are fixed on a base 43, which may be a second guide mechanism as described above, so that the two abutment rods 41 can move synchronously along the Y direction. Referring to fig. 7, when the size of the sheet for placement in the Y direction is smaller than the width of the elevating plate 50, it is possible to provide two through grooves 53 on the elevating plate 50, the through grooves 53 penetrating from the upper surface to the lower surface of the elevating plate 50, and the through grooves 53 extending in the Y direction, one end of the through grooves 53 extending to the side of the elevating plate 50 away from the substrate 10 and forming a notch, the width of the through grooves 53 being set so as to be just capable of being fitted with the abutting levers 41, when the abutting levers 41 are moved in the Y direction toward the substrate 10, the abutting levers 41 are capable of being fitted with the notches of the through grooves 53 and being moved in the Y direction within the through grooves 53, and at the same time, since the through grooves 53 penetrate the upper and lower surfaces of the elevating plate 50, the abutting levers 41 are capable of moving upward and downward in relation to the elevating plate 50 after being fitted into the through grooves 53, the abutting faces 42 thereon are fitted with the substrate 10, and the sheet is capable of being clamped in the Y direction; referring to fig. 8, when there is a relatively large size of the sheets in the Y direction, there is no need for the abutment bars 41 to be placed in the through grooves 53, and the two abutment bars 41 respectively abut against the sheets in the bins a and B; in short, the through groove 53 is provided in the lifter plate 50, so that the abutting piece 40 can be prevented from interfering with the lifter bar 50 while ensuring that the abutting piece can clamp the sheet in the Y direction with the substrate 10 for some small-sized sheets. In the structure of a single silo as shown in fig. 9 and 10, the abutting member 40 'may be plate-shaped, so that the abutting member 40' can better abut against the sheet with larger size, and then better locate the sheet.
