Abstract
The present invention provides a drive controlling apparatus used in a sheet supplying apparatus including a lift/lower sheet supporting device for supporting a sheet, a sheet supply mechanism for feeding out the sheet supported by the sheet supporting device, a biasing mechanism for biasing the sheet supporting device toward the sheet supply mechanism, and a separating mechanism for separating the sheet supporting device from the sheet supply mechanism in opposition to a biasing force of the biasing mechanism, and wherein the sheet urged against the sheet supply mechanism by the biasing mechanism is fed out by the sheet supply mechanism, said drive controlling apparatus adapted to transmit a driving force for operating the separating mechanism from a drive source and comprising a drive side device connected to the drive source, a driven side device connected to the separating mechanism, and a play setting device for providing a play for not transmitting the driving force within a predetermined range between the drive side device and the driven side device.
