AI Technical Summary
Technical Problem
Conventional sheet feeding devices with air-based feeding methods experience prolonged waiting times during job restarts due to the need to stop and restart airflow, leading to inefficiencies in job termination and restart processes.
Method used
A sheet feeding device equipped with airflow generation, transport, detection, and control mechanisms that dynamically manage airflow operations based on retry operation settings, allowing immediate resumption of jobs without waiting for airflow stabilization.
Benefits of technology
The solution significantly reduces waiting times during job restarts by maintaining airflow states, enabling immediate job resumption and minimizing downtime.

Abstract
The present invention provides a sheet feeding device that can reduce the waiting time when a retry operation is performed in a configuration that employs an air-based feeding method. [Solution] A sheet feeding device comprising: an airflow generating means that uses airflow to make the loaded medium transportable; a transporting means that transports the medium that has become transportable by the airflow; a medium detection means that detects the transport status of the medium; and a control means that controls the operation of the airflow generating means and the transporting means during the transport of the medium and determines whether or not there is a transport abnormality in the medium, wherein the control means controls whether or not to execute an operation start process or operation end process of the airflow generating means that is executed in response to a transport instruction for a subsequent medium following the medium being transported, based on a setting related to the execution of a retry operation that is executed after a transport abnormality occurs when the transporting means is transported.
