この発明は給紙装置に関し、特に、少ない部品点数で上
下給紙ローラと第２給紙ローラとの回転、停止の制御を
行うことのできる給紙装置に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a paper feeding device, and in particular, to a paper feeding device that can control rotation and stop of upper and lower paper feeding rollers and a second paper feeding roller with a small number of parts. This relates to a paper feeding device.

されていた。Conventionally, in image forming apparatuses such as electrophotographic copying machines, paper feed cassettes that store paper inside are arranged in two stages, upper and lower.
If the paper feed device is designed to feed the paper in the desired paper feed cassette, it will press against the topmost paper of the stack of paper in the upper and lower paper feed cassettes, and when it rotates. An upper paper feed roller and a lower paper feed roller that feed the paper, and a second paper feed roller that transports the paper fed by either of the paper feed rollers to a transfer unit of an electrophotographic copying device or the like are provided. When rotating and stopping each of these rollers, each roller is connected to a drive source via a clutch, so transmission or non-transmission of the driving force of each clutch is switched. The clutch was engaged and the aforementioned levers were actuated via actuating members to rotate or stop each roller, thereby sending the paper in the desired paper feed cassette to the transfer section. .

ために部品点数が多くなり、したがって装置全体が大型
化するとともに、高価になるという欠点を有していた。However, in the paper feeding device configured as described above, there is a lever that engages and disengages from each clutch in order to activate or deactivate the clutch for transmitting driving force to each paper feeding roller. Since the actuating member is provided, the number of parts increases, and therefore the entire device becomes larger and more expensive.

とを目的とする。The present invention eliminates the drawbacks of the prior art as described above, and reduces the number of levers and their actuating members by using a lever that activates and deactivates each clutch in a fixed relationship. It is an object of the present invention to provide a paper feeding device that can be made compact and inexpensive as a whole.

するようになっている。Each shaft of the main paper feed roller 16, sketch paper roller 17 and second paper feed roller 22 is connected to a clutch 23.24.2, respectively.
A first lever 26 and a second lever 27 are connected to a drive source (not shown) via
and the levers 26 and 27 are provided so as to be rotatable about shafts 28, respectively, and each lever 26, 27 is biased in the direction of the arrow in the figure by a biasing unit assembly 29, 30, and the clutch 2 at the tip in the biasing direction is biased.
3.24.25 to prevent transmission of the drive source, and the first solenoid 31 and the second solenoid
Its state changes depending on whether the solenoid 32 is activated or deactivated.
すなわち、各レバー２６，２７の作用と作動部材である

伝達を阻止するようになっている（第３図）。That is, to explain the relationship between the action of each lever 26, 27 and the activation/deactivation of the second and second solenoids 3, 32, which are actuating members, the lever 26 moves the sketch paper roller 17 when the first solenoid 31 is inactive. It acts with the shaft clutch 24 to prevent the rotational force of the drive source from being transmitted to the lower paper feed roller 17, and also acts on the shaft clutches 23, 25 of the upper paper feed roller 16 and the second paper feed roller 22. does not act, so the rotational force of the drive source is transmitted to the upper paper feed roller 16 and the second paper feed roller 22 (Fig. 2), and the second lever 27 is moved upward when the second solenoid 32 is activated. Paper feed roller 1
6, and prevents transmission of the rotational force from the drive source to the lower paper feed roller 17 and the second paper feed roller 22 (FIG. 3).
また、前記第１ソレノイド３１および第２ソレノイド３

ができるものである。Further, the first solenoid 31 and the second solenoid 3
2 is the opposite operation to the above, that is, the first solenoid 31
is activated and the second solenoid 32 is deactivated, the rotational force is transmitted to each roller 16, 17, 22 in the opposite manner to the above case, and the above-mentioned operation occurs and the second solenoid 32 is inactivated. By combining the activation and deactivation of the two solenoids 3 and 32 that rotate the 26 and the second lever 27, the upper paper feed roller 16, the lower paper feed roller 17, and the second paper feed roller 22 are controlled. and either one of the paper feed cassettes
It is possible to send out the paper in 20 and 21 and convey it to the transfer section.

２の回転は停止する。That is, if the second solenoid 32 is activated while the first solenoid 31 is activated, all cranks 23.2
4.25, the rotational force of the drive source is no longer transmitted, and the upper paper feed roller 16, the lower paper feed roller 17, and the second paper feed roller 2
2 stops rotating.
そして、第１ソレノイド３１が作動中に第２ソレノイド
３２が不作動となると、下給紙ローラ１７のクラッチ２
４のみの係合を解除することで下給紙ローラ１７だけが
回゛転するようになる。If the second solenoid 32 becomes inactive while the first solenoid 31 is in operation, the clutch 2 of the lower paper feed roller 17
By releasing the engagement of only the lower paper feed roller 17, only the lower paper feed roller 17 can rotate.

２給紙ローラ２２だけを回転させる。Furthermore, when the second solenoid 32 is activated when the first solenoid 31 is deactivated, only the clutch 23 of the upper paper feed roller 16 is disengaged, causing only the upper paper feed roller 16 to rotate. , when the second solenoid 32 is deactivated with the first solenoid 31 deactivated, the second solenoid 32 is deactivated.
Only the clutch 25 of the paper feed roller 22 is disengaged, and only the second paper feed roller 22 is rotated.

。Therefore, after rotating either the upper paper feed roller 16 or the lower paper feed roller 17 as described above to feed out the paper within the paper feed power cent.
By controlling the operation and inactivation of the first solenoid 31 and the second solenoid 32 by the control member so that only the paper feed roller 22 rotates, the paper in one of the paper feed cassettes is reliably transferred to the transfer section (shell feeding). It is something that can be done.

Therefore, the entire device can be made smaller, and it can also be made inexpensive, which has excellent effects.
