摘要： An image forming apparatus includes a regulating member for regulating a sheet fed from the magazine in the widthwise direction, the regulating member being movable between a regulating position and a retreating position. The image forming apparatus further includes a cover member for opening and closing the magazine. When the cover member closes the magazine, the regulating member is in the retreating position, and when the cover member opens the magazine, the regulating member is in the regulating position.

摘要： A recording medium detecting apparatus detects the fact that a recording medium has been conveyed to an image forming part of a laser beam printer. The image forming part is provided with a driving roller for producing a rotational motion and a following roller held in pressed contact with the driving roller and consequently allowed to follow the rotational motion. The thrust of the recording medium in between the two rollers is discriminated by the detection of a change in the rotational speed of the driving roller which change is caused by the thrust of the recording medium in between the rollers. In accordance with the result of detection of this thrust, the timing for image formation in the image forming part is controlled. Thus, the arrival of the recording medium at a prescribed destination can be detected without requiring use of a sensor or a switch. Where a plurality of recording media are conveyed in a superposed state, the number of these recording media can be discriminated by detecting the amount of change in the rotation speed. The display part for displaying the residual amount of recording media is controlled in accordance with the number of recording media involved in the thrust. The display part tells the operator the residual amount of recording media.
摘要翻译：记录介质检测装置检测记录介质已被传送到激光打印机的图像形成部分的事实。图像形成部件设置有用于产生旋转运动的驱动辊和与驱动辊保持压接的随后的辊，因此允许跟随旋转运动。通过检测由辊之间的记录介质的推力引起的变化的驱动辊的转速的变化来区分两个辊之间的记录介质的推力。根据该推力的检测结果，控制图像形成部中的图像形成的定时。因此，可以在不需要使用传感器或开关的情况下检测记录介质到达规定的目的地。在多个记录介质以叠加状态传送的情况下，可以通过检测转速的变化量来区分这些记录介质的数量。用于显示剩余量的记录介质的显示部分根据推力所涉及的记录介质的数量进行控制。显示部分告诉操作者记录介质的剩余量。

摘要： A sheet feed arrangement is provided in an image forming apparatus such as a printer or the like and is comprised of a sheet cassette for accommodating a plurality of sheet materials, a feed roller assembly disposed above the sheet cassette for feeding the sheet materials sheet by sheet by contacting with an upper surface of a topmost sheet of the sheet materials accommodated in the sheet cassette, and a tiltable guide plate disposed downstream from the feed roller assembly in a direction of feed of the sheet materials for guiding the sheet materials. The guide member can tilt together with the feed roller assembly so that an end portion of the guide member may be introduced in or removed from an inner end portion of the sheet cassette. The sheet feed arrangement is further comprised of a sheet lifting mechanism disposed below the sheet cassette for listing end portions of the sheet materials when the sheet materials are fed from the sheet cassette. The end portions of the sheet materials are lowered by the sheet lifting mechanism when the sheet cassette is removed from the image forming apparatus.
摘要翻译：在诸如打印机等的图像形成装置中设置有片材进给装置，并且包括用于容纳多个片材的片材盒，设置在片材盒上方的进给辊组件，用于将片材片材片材通过与容纳在片材盒中的片状材料的最上层片材的上表面接触，以及在进给辊组件的下游，沿着用于引导片材的片状材料的进给方向设置的可倾斜导向板。引导构件可以与进给辊组件一起倾斜，使得引导构件的端部可以被引入片材盒的内端部分或从片材盒的内端部移除。片材进给装置还包括设置在片材盒下面的片材提升机构，用于当片材从片材盒送出时，列出片材的端部。当片材盒从图像形成装置中取出时，纸张材料的端部被纸张提升机构降低。
