Benefits of technology
The present invention provides a sheet guiding device and sheet processing apparatus that can smoothly guide and process sheets without fluctuating or experiencing speed differences during transportation. This results in a higher accuracy of processing and stable transportation of the sheets.
Problems solved by technology
However, the guiding device has the following defect.
Hence, it is impossible to perform processing on the sheet transported by the gripping bar, such as checking the outer surface of the sheet with a checking device and printing the outer surface of the sheet.

Abstract
A sheet guiding device includes: gripper bars provided to delivery chains and each having a holding portion configured to hold an end portion of a paper sheet, the gripper bars configured to transport the paper sheet along a paper sheet transporting route spaced away from a travelling route of the delivery chains; a delivery cylinder having a guide surface and configured to guide the transported paper sheet, the guide surface extending along an arc-shaped transporting route portion in the paper sheet transporting route which is located outside an arc-shaped travelling route portion in the travelling route of the delivery chains and which is formed by the holding portion travelling along the arc-shaped travelling route portion; a linear travelling route portion formed downstream of the arc-shaped travelling route portion in a travelling direction of the delivery chains; and a suction guide for guiding the paper sheet to an inner side than the linear travelling route portion, the paper sheet located in a region downstream of a shift position from the arc-shaped travelling route portion to the linear travelling route portion in a sheet transporting direction.
Description
TECHNICAL FIELD[0001]The present invention relates to a guiding device for a sheet which is transported while being held by a sheet holding device provided to a transporting chain and to a sheet processing apparatus including the sheet guiding device.BACKGROUND ART[0002]Patent Literature 1, for example, discloses one of such guiding devices. In this guiding device, a sheet guide is provided to guide a sheet which is transported while being held by a gripper bar provided in a transporting chain.[0003]However, the guiding device has the following defect. Since the sheet guide is provided outside a transporting route of the sheet, an outer surface of the sheet comes in contact with the sheet guide. Hence, it is impossible to perform processing on the sheet transported by the gripping bar, such as checking the outer surface of the sheet with a checking device and printing the outer surface of the sheet.[0004]Meanwhile, Patent Literature 2 describes an apparatus in which a guiding device...
