Abstract

The invention provides a sheet feeding device. A controller drives a floating unit and a conveyor to perform a sheet feed operation, during which the following tracking control is performed: acquiring an amount of received light at a detector during floating of sheets floated by the floating unit each time each sheet is conveyed by the conveyor, and lifting a stacking tray upon the acquired amount of received light being less than a threshold value. The controller, after start of the sheet feed operation, samples amounts of received light at the detector during floating of the sheets floated by the floating unit, performs a threshold value determination process of determining the threshold value by using the sampled amounts of received light, and starts the following control upon determining the threshold value.

Description

technical field [0001] The present invention relates to a sheet feeding device for feeding sheets. Background technique [0002] As a sheet feeding device for feeding sheets, there is known a sheet feeding device that blows air to sheets (bundle of sheets) stacked on a sheet feeding table to blow up the sheets, and sucks the conveying member to blow up the sheets. The uppermost (uppermost) paper is sucked and conveyed and fed to the paper feed destination. [0003] In the paper feeding device described in Japanese Patent Application Laid-Open No. 2019-11150, the following tracking control is performed so that the paper feeding table is raised in accordance with the reduction of sheets on the paper feeding table due to the paper feeding. As the tracking control in this paper feeding device, the following control is performed. The optical sensor acquires the light reception amount (sensor value) based on the reflected light from the blown paper once for each paper fed, and th...
