構成とすると共に、当該機械に用紙なセ。(Prior Art) Conventionally, in order to reduce the manufacturing cost of electrophotographic copying machines, etc., it is necessary to feed the paper vertically from the paper feeding section of the copying machine to the transfer section of the photoreceptor drum. However, to increase the copy speed, in the copying process,
In order to shorten the exposure time of the optical system to the paper, it is necessary to feed the paper horizontally. In order to satisfy these two needs with one machine, the configuration of the machine itself must be capable of both vertical and horizontal paper feeding, and the machine must also have a paper .

てしまうことが多いといった欠点があった。When printing paper, it is necessary to set the paper vertically or horizontally depending on the purpose, and to do this, there are many different sizes of paper, so it is necessary to set the paper vertically or horizontally depending on the purpose. It is necessary to prepare paper for cross-feeding, and it is not only difficult to secure the stock, but also the work is complicated when setting the paper in the machine, and the operation of the machine is also complicated. This causes setting errors and operation errors, which often result in copy errors.

In addition to directly feeding the paper set in the transfer section of the photoconductor drum, if necessary, the paper is rotated 900 times in the paper feed section to convert it to the horizontal feeding direction, and then the paper is fed directly to the transfer section of the photoconductor drum. This paper feeder is designed to greatly reduce the amount of paper in stock by making it possible to feed paper into the machine, and also to make it easier to set the paper in the machine and operate the machine, thereby minimizing the occurrence of copy mistakes. The purpose is to provide a paper device.

にすれば良い。First, in order to vertically feed the paper 6 set on the paper loading table 1 into the transfer section of the photosensitive drum (not shown), the spring-loaded solenoid 1 of the switching mechanism 13 is used.
Turn on the plunger 1 of the spring-loaded solenoid 10.
1 against the elasticity of a spring 140 wound around its outer periphery, the spring clutch 12 connected to the plunger 11 is connected to simultaneously rotate the inner and outer shafts 4 and 5, All you have to do is start the motor 8, and by applying pressure in this way, the paper 6 set on the paper loading table 1 in a longitudinal direction will be fed in a direction of Km from above to the transfer section of the photosensitive drum. Paper is fed and goes. On the other hand, in order to feed the paper 6 set vertically on the paper table 1 in a horizontal direction, the spring-loaded solenoid 10 is turned off.
F, the plunger 11 is returned to its original position by the restoring force of the spring 14 wound around its outer circumference, thereby disengaging the spring clutch 12 and stopping the rotation of the paper feed roller 3 fixed to the outer shaft 5. In this state, motor 8
When the paper 6 is rotated, the topmost sheet of paper 6... is rotated by the rotation of the paper feed roller 22 with the paper feed roller 3 as the fulcrum, and the paper 6... is rotated by the arrow B in the figure.
Since it rotates 90 degrees in the horizontal direction shown by K and becomes a cross-feeding shape,
At this time, a command is issued from a controller or the like (not shown) to turn on the spring-equipped solenoid 10, reconnect the spring clutch 11, and rotate the paper feed row 24 simultaneously with the paper feed row 23 again. The above operation may be repeated thereafter.

併有する。(Effects of the Invention) The present invention is configured and operates as described above, and feeds the paper set on the paper loading table l of the paper feeding unit to the transfer unit of the photosensitive drum. In this case, it is possible to feed paper by selecting the feeding direction either vertically or horizontally as necessary, so even if there are many different sizes of paper 6, it is possible to feed the paper vertically or horizontally for each paper size. It is no longer necessary to prepare paper for each state, and therefore the amount of paper stocked can be reduced accordingly, which helps reduce stock costs, and the paper setting work and machine operability are also easier than conventional paper feeding. Depending on the direction, it is much easier to set the paper on the table 1 vertically and horizontally, eliminating errors in setting the paper and operating the machine, and reducing errors caused by these. It has the effect of significantly reducing the number of copies and helping to conserve resources.Also, when attaching a paper output tray to a machine, there is no need to change the paper output tray one by one according to the paper feeding direction, which reduces bone strength. It also has the effect of helping you save money.
