Title:
SHEET CONVEYER
Document Type and Number:
Japanese Patent JP3842317
Kind Code:
B2
Abstract:
PURPOSE: To provide a sheet conveyer of simpler structure by extensibly/ contractibly connecting a plurality of flat tubular sheet with its inside serving as a conveying path of a sheet.
CONSTITUTION: In a condition that an upper paper feed unit 3 is lifted, a series of sheet guides 9 are extended to connect between the upper paper feed unit 3 and an image forming device 1. By a paper feed command, a sheet 6 on a paper feed tray 5 is fed into the uppermost step sheet guide 9 by a paper feed roller 25. By detection of a sensor in the uppermost grade sheet guide 9, conveying rollers 12 are rotated and the sheet 6 interposed therebetween is fed downward. When the sheet 6 passes through inside the second step sheet guide 9 with the lower edge leading to the third step sheet guide 9, by detection of the third step sensor, the third step conveying rollers 12 are rotated to feed the sheet downward. Hereinafter, similarly the sheet 6 is fed to the image forming device 1. In a condition that the upper paper feed unit 3 is lowered down, a series of the sheet guides 9 are short contracted.
