    • PURPOSE: A quick sheet feeding device and an image forming device are provided to accurately lock a sheet loading part by simple operation without using a lock member and to prevent the damage of the lock member. CONSTITUTION: A quick sheet feeding device comprises a receiving part, a fast feeding part(4), a pulse motor, a contact part, an one-way clutch, and a controller(5). The receiving part comprises a liftable sheet loading part. The fast feeding part quickly feeds sheets loaded on the sheet loading part. The pulse motor lifts up the sheet loading part. The contact part contacts the sheet loading part ascended by the pulse motor at a predetermined position and enables the sheet loading part to be locked on the receiving part. The one way clutch is freely rotated in a direction of the ascended sheet loading part. The rotation of the one way clutch is locked in a direction of the descended sheet loading part. The controller rotates the pulse motor in the direction of the ascended sheet loading part. Even after the seat loading part is contacted to the contact part, the controller additionally rotates the pulse motor in same direction to step out. After the pulse motor is stepped out, the controller cuts an electric current applied to the pulse motor. [Reference numerals] (5) Controller
    • 目的:提供快速送纸装置和图像形成装置,以便通过简单的操作来精确地锁定纸张装载部分而不使用锁定构件并防止锁定构件的损坏。 构成:快速送纸装置包括接收部分,快速馈送部分(4),脉冲电动机,接触部分,单向离合器和控制器(5)。 接收部分包括可升降的片材装载部分。 快速进给部分快速进给装载在纸张装载部件上的纸张。 脉冲电机提升纸张装载部分。 接触部分在预定位置处接触由脉冲电机上升的片材装载部分,并使得片材装载部分被锁定在接收部分上。 单向离合器沿上升的纸张装载部分的方向自由旋转。 单向离合器的旋转被锁定在下降的纸张装载部分的方向上。 控制器沿上升的纸张装载部分的方向旋转脉冲电动机。 即使在座椅装载部分接触到接触部分之后,控制器另外旋转同一方向的脉冲电动机以逐出。 脉冲电机出门后,控制器切断施加到脉冲电机的电流。 (附图标记)(5)控制器
