Title:
SHEET TRANSPORT DEVICE AND RECORDING DEVICE
Document Type and Number:
Japanese Patent JP2016150792
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To achieve a highly accurate sheet transport by reducing friction that can occur on the rear side of a transport belt in a sheet transport device that transports a sheet while being sucked onto the belt.SOLUTION: A negative pressure generated in a suction chamber 204 is exerted through a transport belt 201 onto a sheet 102 so as to cause the sheet 102 to be sucked onto the transport belt 201. A plurality of belt surface holding rollers 205 are disposed in this configuration. This makes it possible to reduce friction between a rear surface of the transport belt and a suction mechanism, such as a suction chamber, when the transport belt 201 travels for transporting the sheet, even under application of an adsorption pressure as relatively strong as -8 kPa. This contributes to reducing cockling or the like, making it possible to hold the sheet flat and transport the sheet with high accuracy.SELECTED DRAWING: Figure 2
