A currency evaluation device for receiving a stack of currency bills and rapidly evaluating all the bills in the stack. Two of the divided cells are arranged without being turned upside down such that oblique sides thereof oppose each other; thus, a substantially rectangular-shaped unit is configured. Further, it is understood that the above are performed for each clock domain within the integrated circuit design. A first value is selected in the plurality of values representing reference voltages. The sheet conveying section has a sheet standby unit including a stacking device for stacking a predetermined number of sheets in a linear state, and a bundle conveying device for conveying the sheet bundle stacked in a linear state, whereby the predetermined number of sheets are conveyed to the sheet processing section after having been stacked in a linear state. The present invention further discloses a system and a corresponding device for beam forming transmission.
