摘要： A document size detecting device with the arm (3) which folds by interlocking with the reciprocating motion of the optical system of the image forming apparatus and extends and contracts by interlocking with the reciprocating motion of the optical system. The optical sensor (37) for detection of the document size is installed at a prescribed position of the arm(3) and the feeder line (11a) for the light source (11) is held. Therefore, the special mechanism for holding the feeder line (11a) is not necessary and it is possible to achieve simplified construction of the image forming apparatus. Also, because the feeder line (11a) is caused to curve along the outside of the arm (3) at the rotating section thereof, it is possible to provide a large radius of the bent portion of the feeder line (11a) there will be no considerably concentrated stress which is locally applied to the feeder line (11a), therefore the life of the feeder line (11a) can be extended.
摘要翻译：具有臂（3）的文档尺寸检测装置，其通过与图像形成装置的光学系统的往复运动互锁而折叠，并且与光学系统的往复运动互锁地延伸和收缩。用于检测文件尺寸的光学传感器（37）安装在臂（3）的规定位置，并且保持用于光源（11）的馈线（11a）。因此，不需要用于保持馈线（11a）的特殊机构，并且可以实现图像形成装置的简化结构。此外，由于在其旋转部分使得馈线（11a）沿着臂（3）的外侧弯曲，所以可以提供馈线（11a）的弯曲部分的大半径，没有局部施加到馈线（11a）的相当集中的应力，因此可以延长馈线（11a）的寿命。

摘要： A copying paper feeding device comprising first and second paper loading sections (2a, 2b) for carrying respective stacks of copying paper sheets. First and second paper delivery mechanisms (10a, 10b) disposed respectively in the first and second paper loading sections (2a, 2b). First and second paper introducing passages (16a, 16b) extend respectively from the first and second paper loading sections (2a, 2b) and terminate in a common junction point from which a single paper conveying passage (30) extends. A first conveyor roller pair (36) is disposed in the first paper introducing passage (16a), and a second conveyor roller pair (38) is disposed at said point of junction or at an upstream part of the paper conveying passage (30). In performing a copying process, either the first or second paper delivery mechanism is selectively actuated. The first and the second conveyor roller pairs (36, 38) are interlocked with each other, and adapted to be started after the first or second paper delivery mechanism has been actuated. When the first paper delivery mechanism (10a) is selectively actuated, the roller pairs (36, 38) are started earlier by the time required to convey a copying paper from the first conveyor roller pair (36) to the second conveyor roller pair (38) than when the second paper delivery mechanism (10b) is actuated. The first conveyor roller pair (36) exerts position-correcting and synchronism-adjusting actions on a copying paper sheet delivered from the first paper loading section (2a), and the second conveyor roller pair (38) exerts position-correcting and synchronism-adjusting actions on a copying paper sheet delivered from the second paper !oadina section (26).

摘要： A detecting device for detecting the amount of toner in dual component developing material is less than the predetermined level in a developing device for an electrostatic copying apparatus which comprises a hopper (4) for supplying the toner (5), a stirring roller (9) for stirring a carrier and the toner (5) from the hopper (4), detecting means for detecting the amount of developing material provided near the stirring roller (9) to mix the toner (5) supplied from the hopper (4) with the carrier, discriminating means for discriminating the output signal from the detecting means for predetermined interval during the rotational period of the stirring roller (9), and an indicating element (46) in response to the output signal from the discriminating means for indicating the amount of the toner (5) in developing material is less than the predetermined level. Since it is indicated when the toner (5) in the developing material is more reduced than the predetermined level, the toner (5) is supplied according to the indication, therefore, the undesirable detrioration of the copy density is prevented.
