Abstract
Official abstract text for this publication.
User labor relating to determining on an alignment condition is reduced and a stable conveying operation is realized by aligning a sheet bundle also when a sheet bundle is added. A sheet bundle composed of multiple sheet materials is placed on a loading platform. An encoder pulse unit detects the amount of the sheet bundle placed on the loading platform based on the opening amount of a pressure plate. A control unit determines on an alignment condition according to the amount of the sheet bundle. Rotating members align the sheet bundle in accordance with the alignment condition. When it is determined that another sheet bundle has been added to the loading platform, the control unit updates the alignment condition according to the total amount of the other sheet bundle and the sheet bundle remaining on the loading platform.
First claim
Opening claim text (preview).
What is claimed is: 1. A sheet material take-in apparatus comprising; an apparatus body having a loading platform on which a sheet bundle is loaded; a take-in unit configured to take in a sheet material of the sheet bundle to an interior of the apparatus body; a detecting unit configured to detect movement of the take-in unit in a direction away from the loading platform; and a control unit configured to control an operation of the take-in unit, wherein in response to the detecting unit detecting the movement of the take-in unit in the direction away from the loading platform during a sheet take-in operation taking in a sheet material to the interior of the apparatus, the control unit stops the sheet take-in operation by the take-in unit. 2. The sheet material take-in apparatus according to claim 1 , wherein an operation unit is provided on the apparatus body, and the control unit temporarily stops a sheet take-in operation based on a detection result of the detecting unit, and then resumes the sheet take-in operation based on an operation of the operation unit. 3. The sheet material take-in apparatus according to claim 1 , wherein the detecting unit includes a sheet bundle adding detection unit configured to detect addition of a sheet bundle to the loading platform.
