Abstract

PURPOSE:To sharply reduce an amount of appers stocked, by a method wherein, when papers are set in a device, the papers are arranged in either a longitudinal or a lateral direction, and the direction of the papers is freely changed longitudinally and laterally, where necessary to feed the papers to the transfer part of a sensitizing body drum. CONSTITUTION:In order to laterally feed papers 11, set on a paper placing table 1 in a longitudinal feed manner, to the transfer part of a sensitizing body drum, solenoids 6 and 6' with a spring are turned ON, plungers 7 and 7' are attracted against elasticity of springs 20 and 20', and support plates 4 and 4' are rotated upward around stationary shafts 5 and 5' serving as a fulcrum. This rotation results in lifting of a feed paper roller 2, mounted to the shaft 3, from the paper 1. With this, a motor 15 is driven, the paper placing table 1 is turned in a 90 deg. arc in a horizontal direction shwon by an arrow mark A around the rotary shaft 12 serving as a fulcrum. At a point of time when the table 1 makes contact with the actuator of a switch 18 and is brought to a stop, the solenoids 6 and 6' are turned OFF, and the papers 11 are fed in a lateral feed manner through driving of the motor 8 in a condition in which the feed rollers 2 are lowered on the paper 1.

た欠点があった。(Prior Art) Conventionally, in order to reduce the manufacturing cost of electrophotographic copying machines, etc., the feeding direction of the paper from the paper feeding section of the copying machine to the transfer section of the photoreceptor drum is vertically fed. In addition, in order to increase the copying speed, it was necessary to change the direction in which the paper is fed horizontally in order to shorten the exposure time of the optical system to the paper in the copying process. In order to satisfy these two needs with one machine, the configuration of the machine itself must be such that it can feed both vertically and horizontally, and when setting paper in the machine, Depending on the purpose, it is necessary to use the paper in a vertical or horizontal format, and for this purpose, as there are many different paper sizes, it is necessary to prepare paper for each size for vertical and horizontal formats. Not only is it difficult to ensure that the paper is properly placed, but the task of setting the paper in the machine is complicated, and the operation of the machine is also complicated, which can lead to setting mistakes and operational errors. This has the disadvantage that there are many cases where copy errors occur due to this.

This can be changed vertically and horizontally as needed to feed paper to the transfer section of the photoreceptor drum, greatly reducing the amount of paper stocked and improving the work of setting the paper in the machine and the operability of the machine itself. The object of the present invention is to provide a paper feeding device that is easy to use and reduces the occurrence of copy errors as much as possible.

The shafts of these paper feed rollers are made vertically movable by using lifting means such as spring-loaded solenoids, and a rotating shaft is provided at an appropriate location on the bottom surface of the paper loading table, and a curved shape is provided around the rotating shaft. While a rack was provided, a motor was placed at an appropriate position below the paper mounting table, and a bevel gear fixed to the tip of the shaft of the motor was meshed with the rack, and the paper was set in a vertical feeding manner on the paper mounting table. When feeding paper directly to the transfer section of the photoconductor drum, feed the paper using a paper feed roller without moving the paper loading table, and when feeding paper horizontally, move the paper feeding roller onto the paper loading table. Pull up the set paper upwards, and in this state, rotate the motor installed at the bottom of the paper loading table to change the direction of the paper loading table to the horizontal direction. Then, the paper feed roller is pulled down to the top of the paper and brought into contact with the paper, and the paper is fed in this state.

部へ横送り状に給紙されて行くととＫなる。First, the paper 11 set vertically on the paper table 1.
When feeding paper as it is to the transfer section of the photoreceptor drum, the paper loading table 1 does not rotate the paper feed roller 2 attached to the shaft 3, but uses a spring-loaded solenoid to By turning off solenoid 6.6', the plunger 7.7' of the solenoid 6.6' is pushed down by the elastic force of the spring 20.20' wound around its outer periphery.
The support @ 4.4' connected to the branjaf 7' is brought into contact with the support @ 4.4' by pulling it down using the fixed shaft 5.5' as a fulcrum, and the motor 8 is rotated. Paper 11 set vertically on the tray 1.
... are fed to the transfer section of the photosensitive drum as shown by arrow CK in the figure. On the other hand, the spring-loaded solenoid 6.6 is used to feed the paper set on the paper table 1 in a vertical manner to the transfer section of the photosensitive drum in a horizontal manner.
'Turn on the plunge-y-7, 7' spring 20.2
0', the support plate 4.4' is rotated upward about the fixed shaft 5.・
...Pull it up from above, and in this state, rotate the motor 15 to move the paper table 1 in the direction of the arrow AK with the rotating shaft 12 as the fulcrum.
When the sheet loading table 1 contacts the actuator of the switch 18 and stops, the spring-equipped solenoid 6.6' is set to OFP K and the sheet feeding roller 2 is rotated 90' in the horizontal direction shown in FIG.
All you have to do is pull down the paper 11... onto the paper 11... and rotate the motor 8. If you do this, →, the paper 11... set on the paper table 1 will be transferred to the photoreceptor 1 drum. When the paper is fed horizontally to the section, it becomes K.

When feeding the paper set on the paper loading table 1 of the paper feeding section to the paper feeding section of the photosensitive drum, the feeding direction of the sheet is rotated by 90 degrees as necessary. Therefore, even if there are many paper sizes, it is necessary to prepare paper for vertical feeding and horizontal feeding for each paper size. This will help reduce stock costs as the amount of stock can be reduced accordingly.
The work of setting the paper and operating the machine becomes extremely easy, eliminating mistakes in setting paper and operating the machine, and greatly reduces the occurrence of copy mistakes caused by these, helping to conserve resources. It also has the effect of
Further, when attaching a paper discharge tray to a machine, there is also the effect that there is no need to switch the paper discharge tray one by one according to the feeding direction of the paper 11 .
