A recently granted patent (Publication Number: US11667485B2) describes a sheet conveyance apparatus that is used to transport sheets from one processing apparatus to another. The apparatus includes a conveying unit, a conveying unit drive mechanism, a sheet accumulation area, and a control unit. The conveying unit is responsible for moving the sheets, while the conveying unit drive mechanism powers the movement. The sheet accumulation area is where the sheets are collected after being fed out of the upstream sheet processing apparatus.

The control unit plays a crucial role in managing the conveyance of the sheets. It includes a counter unit that keeps track of the number of sheets accumulated in the sheet accumulation area. When a conveyance instruction signal is received and the counter unit determines that only one sheet is currently accumulated, the control unit stops the conveyance of that sheet until the next sheet is guided onto it. This ensures that the sheets are conveyed one by one, preventing any potential issues or jams.

Additionally, the control unit has a sheet number determination unit that determines whether there are two or more sheets accumulated or just one. If there are two or more sheets, the control unit proceeds to convey the sheets from the accumulation area. This feature allows for efficient and timely conveyance of multiple sheets.

Furthermore, the control unit includes a final sheet determination unit that identifies whether the sheet currently in the accumulation area is the final sheet to be processed. If it is determined to be the final sheet, the control unit initiates the conveyance of that sheet. This ensures that the final sheet is properly processed and avoids any unnecessary delays.

The patent also mentions an airflow hole formed in the conveying unit and a suction switch mechanism. This mechanism allows for the control of suction on the sheet through the airflow hole, providing additional control and flexibility in the conveyance process.

In addition to the apparatus, the patent also covers a control method for the sheet conveyance apparatus and a non-transitory computer-readable storage medium that stores a control program for the apparatus.

Overall, this patent presents an innovative sheet conveyance apparatus with advanced control features that ensure efficient and reliable sheet processing between different apparatuses.
