摘要： A sheet feeding apparatus includes a sheet stacking portion for stacking a sheet, a sheet feeding roller for feeding the sheet stacked on said sheet stacking portion, a supporting member, rotatably supported by a base member, for rotatably supporting said sheet feeding roller, and a spring stretched between the base member and an acting portion of the supporting member. The acting portion of the supporting member is located downward with respect to a rotation center of the supporting member when a sheet stacking amount is small, and the acting portion of the supporting member is located upward with respect to a rotation center of the supporting member when a sheet stacking amount is large.

摘要： This invention relates to an apparatus and method capable of appropriately preventing a printing medium from being diagonally conveyed upon feed regardless of changes in printing medium feed conditions. In this invention, the maximum output value of a PWM signal is compared with the sum of a predetermined bias value and the PWM signal when a sensor detects the tip of a fed printing medium. If the sum is smaller than the maximum output value, it is monitored that the value of the PWM signal increases by the bias value. If the sum is equal to or larger than the maximum output value, it is monitored that the conveyance speed of the printing medium becomes smaller than a predetermined threshold value. Control is performed on the basis of the monitor results to stop driving a DC motor that supplies a driving force to rollers used for feed and conveyance.
摘要翻译： 本发明涉及一种能够适当地防止打印介质在进纸时被对角地输送的装置和方法，而与打印介质进给条件的变化无关。 在本发明中，当传感器检测到所馈送的打印介质的末端时，将PWM信号的最大输出值与预定偏置值和PWM信号之和进行比较。 如果总和小于最大输出值，则监视PWM信号的值增加偏置值。 如果总和等于或大于最大输出值，则监视打印介质的传送速度变得小于预定阈值。 根据监视结果进行控制，停止驱动供给驱动力的直流电动机用于进给和输送的辊子。
