摘要： PURPOSE:To form a copying machine having the higher reliability by prohibiting the acceptance of an automatic start mode when abnormality arises in the machine. CONSTITUTION:Detection of abnormality is executed right after throwing of an electric power source. The abnormality is displayed and the acceptance of the automatic start is prohibited when the abnormality arises. The state of accepting condition setting is attained when the operator pushes down an automatic start mode key 6 during the rise time when the abnormality is not detected. The condition setting is accepted here and the automatic start is released when the operator pushes down again the key 6. The state of the initializing the setting condition is thus attained.

摘要： PURPOSE:To increase the hooking force between a sector gear which turns an arm shaft and a driving gear and to prevent a fault to be caused at the rise of the cassette bottom plate, by attaching a push-up driving motor, the push-up driving gear and a gear train to a bracket which is freely rockably supported by a shaft attached to a device frame. CONSTITUTION:A stopper 27 set on a pressure arm 26 usually abutted on an edge 24a of a counter bracket 24 regardless of attachment or detachment between a driving gear 16 and a sector gear 11. A tension spring 30 having considerably large power is stretched between a point 31 on the bracket 24 and a point 32 on the arm 26. As a result, the stopper 27 is press-contacted to the edge 24a. Thus both the bracket 24 and the arm 26 rock in a body round a shaft 22.
摘要翻译：目的：通过安装上推驱动电机，增加转动臂轴的扇形齿轮与驱动齿轮之间的钩挂力，并防止在盒底板上升引起故障时，上推驱动齿轮和齿轮系连接到支架上，该支架由连接到装置框架的轴自由地摆动地支撑。构成：设置在压力臂26上的止动件27通常抵靠在支架24的边缘24a上，而与驱动齿轮16和扇形齿轮11之间的连接或拆卸无关。具有相当大功率的拉伸弹簧30在支架24上的点31和臂26上的点32.结果，止动件27被压接在边缘24a上。因此，托架24和臂26两者在主体22中围绕轴22摇动。

摘要： PURPOSE:To sweep away forcibly foreign matters stuck to a body of rotation, by providing a rotary cleaning member which faces the body of rotation and is brought into contact with the body of rotation and is rotated while generating the surface slippage between the body of rotation and itself. CONSTITUTION:A paper ejecting roll 14 follows up a paper ejecting roll 13 to rotate by the rotation of the roll 13, and a cleaning roll 26 follows up the roll 14 to rotate by the rotation of the roll 14. Though a rotating force F of the paper ejecting roll 14 is transmitted to the cleaning roll 26 to rotate the roll 26, the force in the direction of the transmitted rotation is Fcostheta and a force Fsintheta acts in the direction of a supporting shaft 23 because the cleaning roll 26 is arranged in the position twisted at an angle theta. Consequently, a load in the direction other than the rotation direction is applied to the paper ejecting roll 14 by this force Fsintheta in the direction of the supporting shaft 23 to generate the surface slippage between both rolls, and an unfixed toner or the like which is stuck to the paper ejecting roll 14 is swept away forcibly. Thus, the stuck toner is removed by the cleaning roll 26 before the paper ejecting roll 14 is rotated once.
摘要翻译：目的：通过提供旋转清洁部件，以抵抗旋转体旋转并与旋转体接触并旋转，同时产生旋转体之间的表面滑动，从而扫除被强制旋转的强制异物和本身。构成：纸排出辊14跟随纸排出辊13，以通过辊13的旋转而旋转，并且清洁辊26跟随辊14通过辊14的旋转而旋转。尽管旋转力F 纸张排出辊14被传送到清洁辊26以使辊26旋转，沿着传送的旋转方向的力为Fcostheta，并且力Fsintheta在支撑轴23的方向上作用，因为清洁辊26布置在位置以角度θ扭曲。因此，通过该力Fsintheta在支撑轴23的方向上向除了旋转方向的方向的负载施加到纸排出辊14上，以产生两个辊之间的表面滑动，以及未定影的调色剂等卡在纸排出辊14被强行扫掠。因此，在纸排出辊14旋转一次之前，通过清洁辊26去除粘着的调色剂。

摘要： PURPOSE:To prevent troubles that a toner is scattered in the dry type and a developer is flowed out in the wet type when a machine is operated in case of absence of a photosensitive body, by providing a means which stops the machine operation while interlocking with the low-level output which is detected by a separation miss sensor when the photosensitive body is absent. CONSTITUTION:A separation miss sensor 11 is provided for the purpose of preventing various troubles such as the damage of a photosensitive drum 1 due to winding of a transfer paper around the drum 1, flowing-out of a cleaning liquid, etc. in case of a separation miss of a separating part after transfer. The reflected light from the photosensitive drum 1 is detected at the copy start time so set a certain level to the separation miss sensor 11. If the photosensitive body is absent, the level of reflected light very lower than that for entrance of the transfer paper and only the photosensitive body is detected by the separation miss sensor 11, and the machine operation is stopped to display the abnormality.
摘要翻译：目的：为了防止调色剂在干式中分散的问题，并且当机器在没有感光体的情况下操作时，显影剂以湿式流出，通过提供一种在与当感光体不存在时由分离缺失传感器检测到的低电平输出。构成：为了防止各种故障，例如感光鼓1由于卷筒1周围的转印纸的卷绕，清洗液体的流出等而被提供，因此在这种情况下转移后分离部分的分离缺失。在复印开始时间检测来自感光鼓1的反射光，从而对分离缺失传感器11设定一定程度。如果感光体不存在，则反射光的水平比转印纸的进入速度低得多，只有感光体被分离缺失传感器11检测到，并停止机器操作以显示异常。

摘要： PURPOSE: To positively bias a transfer sheet and prevent defoemation of the transfer sheet by detecting the thickness of the trnsfer sheet and pressing a transfer sheet pressing member by a force corresponding to the thickness of the transfer sheet and biasing the same.
CONSTITUTION: A projection 1a is provided at the upper part of the inner surface of a side wall of a paper-feed cassette 1, and a transfer sheet detecting link 2 is pivotallty connected by means of a pin 3. The upper end 2a of the transfer sheet detecting link 2 is made contact with the upper surface of the transfer sheet 4 heaped within the paper-feed cassette 1. At the lower end 2b of the transfer sheet detecting link 2 there is pivotally connected the back surface of a pressing body 5 made of an elastic body such as a sponge or the like. The front surface 5a of the prssing member 5 is made contact with one side 4a of the transfer sheet 4. As a result, when the number of transfer sheets 4 is reduced, the pressing force becomes weak, and when the number of transfer sheets 4 is increased, the pressing force become strong.
