Abstract

PURPOSE:To make an operation easier and faster by driving a driving device itself by means of gears so that rotating directions and the speeds thereof are obtd. regardless of the various distances of the disposing position thereof. CONSTITUTION:A driving shaft 14 is rotated by starting a driving motor 13 disposed in front of the central part of a lower frame. Then the driving force thereof is transmitted from worms 16, 16', 16'' provided at proper points to the outside circumference of the shaft 14 to worm gears 8-10, 12 and to a driving shaft 4 of a developing machine, a driving shaft 6 of a paper feeder, a driving shaft 7 of a cleaning device and a driver 7a of a shaft 7 from which the driving force is transmitted further to a driving shaft 6 of a photosensitive body, a driving shaft 11 of a fixing machine, etc. The above-mentioned shafts 4-7, 11 are consequently rotated in the prescribed directions at the prescribed speeds. The intricate operations of the machine necessary for the copying operation are thus easily and surely executed by the revolution of one driving motor 13 in one direction in the case of an electrophotographic copying machine, etc.

(Prior Art) Conventionally, in an electrophotographic copying machine, driving force is transmitted from one drive motor to each element of the machine such as a working machine, a paper feeding device, a photosensitive drum, a printing device, a fixing device, etc. There were two ways to do this: chain drive and gear drive.

However, in chain drives, tension adjustment and maintenance,
There is a problem of machine space due to routing etc., there is also an inaccurate drive due to the length of the chain, and furthermore, the machine itself is composed of an upper frame and a lower frame like Waniro Taibu's, and the lower frame is If the upper frame opens and closes, there is a disadvantage that it requires a very long transmission path for the driving force.In contrast, gear drive is a gear drive that opens and closes the machine, so the transmission of driving force is difficult. It is no longer necessary to take a very long path, but instead, multiple stages of gears are required to transmit the driving force from the drive motor to each element of the machine that is located far away, and the installation of the gears requires a lot of materials. Since a large number of machines are required, the machine itself becomes very complicated, resulting in disadvantages such as an increase in production cost and an increase in the frequency of failures.

(Structure of the Invention) Therefore, the present invention provides an electrophotographic copying machine or the like in which the main body of the machine is divided into an upper frame and a lower frame, and the upper frame is provided so as to be openable and closable with respect to the lower frame.
Each element of the machine, such as the developing machine, paper feeding device, photoreceptor drum, and cleaning device, is placed on the lower frame, while a drive motor, etc., is placed on the lower frame in the same manner as the current aircraft. As a means for transmitting the necessary driving force to the driving shaft of each element, for example, the direction of gear cutting is set in the correct position of the driving shaft of the motor in accordance with the rotational direction of the driving shaft of each element of the machine. A suitable number of worms, etc., which serve as reverse gears are provided, and the driving force is transmitted from these worms to the drivers of the driving shafts of each of the above-mentioned elements via worm gears with different outer diameters according to the difference in the rotational speed of the shafts. In this way, one motor can provide 5K of driving force for all the elements of the machine arranged at different distances and positions.
