Abstract

PURPOSE:To let directional properties in the setting of a cassette have the degree of freedom, by installing a setting port capable of setting the cassette loaded with sheets even from at least one more direction to the inside of a device body, besides the regular setting port from a usual sheet feeding direction. CONSTITUTION:Sheet materials 6 are fed out of a cassette 2 one by one by means of rotation of a pickup roller 7 whereby each sheet arrives at a sensitive drum 1 by way of a slip conveying device 10 and a register roller 13. And, each of these sheets 6 already transferred by means of discharge from a corona discharger 17 is delivered to a tray 20 via a fixing device 19. In the above process, a cassette insertion port 34 is installed at the lower side of a left side cover 33 while another cassette insertion port 36 is installed also at the lower side of a right side cover 32. With this, in time of loading and unloading the cassette 2, a projecting part 2' of the cassette 2 is attached or detached to or from a hollow part 30' of a bottom plate 30 by using a handle (a) or another side handle (b) whereby passing through the insertion port 34 or 35, thus the cassette 2 can be loaded from both sides.

Description

[Detailed Description of the Invention] Each AT machine, etc. (hereinafter referred to as a copying machine, etc. ), and in particular, relates to a cassette mounting device that improves the directionality of cassette mounting.

Conventionally, in this Yuzu cassette loading device, one position was set for loading the cassette into a copying machine, etc., and the loading was always done from one direction in the loading section. Therefore, when placing a copying machine, etc., it is not possible to place the side with the cassette loading part close to the wall or the side with the shelf, etc. (the arrangement of the copying machine, etc. had to be changed). In addition, cassettes are usually attached to a copying machine by an operator with his or her right or left hand, and the cassette has the disadvantages of being inconvenient and easy to operate personally. be.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a new cassette mounting device that is improved in view of these drawbacks.

Another object of the present invention is to provide a cassette mounting device that allows flexibility in the direction of cassette mounting.

That is, the main structure of the present invention that can achieve the above object is a cassette mounting device that removably mounts a cassette loaded with sheets into the main body of the device. - In addition to a first cassette mounting opening for mounting a cassette from the feeding direction, a plurality of cassette mounting parts each having a second cassette mounting opening for the cassette that can be mounted from the other direction. This is a cassette loading device characterized by comprising:

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a cross-sectional view showing a main part of a sheet material conveyance path to which an embodiment of the present invention is applied, and 1 in the figure is a photosensitive drum rotating in the direction of the arrow. The drum has a light guide 1M, m. Note that the image forming means, developing means, and cleaning means for removing residual toner after transfer are not shown in the figure.

On the other hand, the sheet) 1, which is conveyed in synchronization with the image on the photosensitive drum 1, is collected on the middle plate 6 in the cassette 2 provided at the bottom, and the middle plate 6 is moved by the spring 4. At least during feeding, the sheet material B is pushed upward, and the height of the sheet material B is kept constant by the separating claws 5. The sheet material 6Fi is fed out one by one from the cassette 2 by rotation of a pickup roller 7 having a part of its circumference cut out. The fed-out sheet material 6 is guided by a guide plate 8-9, passed through a slip conveyance means 10, further guided by a guide plate 11-12, and reaches a register roller 16. Then, the register roller 16 starts rotating in synchronization with the document feeding, and the guide plate 14
- The transfer material 6 is guided by the drum 15 and reaches the drum 1. A separation belt 16 is attached to the side end of the drum 1,
While one end of the sheet material B is separated from the drum 1, a potential is applied by discharge from the corona discharger 17, and the toner image on the drum 1 is transferred to the sheet material. After the transfer, the sheet material is separated from the citram 1 by the belt 16 and conveyed to the fixing means 19 by the conveyor belt means 18. The sheet material to which the toner image is fixed via the fixing means 19 is
(It is carried out to several trays 20.

Next, the mounting portion of the cassette 2 will be explained. A first cassette insertion opening 64 is provided on the lower side of the left cover 66 of the apparatus, and the cassette 2 is pushed through the insertion opening 64 along the bottom plate 30 of the apparatus. At this time, hold the handle a attached to the left end of the cassette 2 and push it in. The protrusion 21 attached to the bottom of the cassette 2 can fall into the recess 30' provided on the bottom plate 60, and the depressed part is the predetermined position of the cassette 20 for feeding paper. be. After the pickup roller 7 is set in the specified position, press the copy switch (not shown).
rotates in the direction of the arrow, and one sheet material is fed into the device.

When the sheet material of the cassette material runs out or when replacing the cassette, pull out the cassette 2 (at this time, pull it out to the left (at this time, hold the handle a, and when pull it out to the right, use the same grip as the handle a). The cassette 2 can be pulled out in each direction by holding the handle attached to it.At this time, there is also a second cassette insertion slot 66 under the right cover 65 of the device.
Because of this, the cassette 2 can also be pulled out on the right side.

Also, since the protrusion 21 of the cassette that was fitted into the recess 60' of the bottom plate 60 is sloped, it is difficult to pull the cassette 2 (
In particular, the cassette will come off when the cassette 60' is raised.

Similarly, when loading the cassette 2 into the apparatus from the right side, the cassette 2 can be inserted through the cassette insertion opening 66.

The protrusion 2' falls into the recess 30' to set the cassette 2 in a predetermined position.When the cassette 2 is set in a predetermined position, the cassette handle a-
This means that b appears.

From the above, by providing cassette insertion ports on both the left and right sides, the cassette can be inserted from either the left or the right, and can be set at a predetermined position in the device.

Similarly, when pulling out the cassette, you can pull it out from either side (Ill), which has cassette handles on both sides.

Figure 2 is a cross-section taken along line A-A in Figure 1.

is installed.

In FIG. 1, the handle a if! is inserted from the first cassette insertion slot 64.
1 or the second cassette insertion slot 66
If it is inserted from the handle b 1llllll, the sheet material will be in the opposite direction and the sheet material will not be fed.

Therefore, as a measure to prevent incorrect insertion, a protrusion 2' is used on the wall of one side of the cassette 20 as shown in FIG.
It is as it should be.

In the embodiment, the cassette is pulled out to the left and right with respect to the front of the apparatus, but the cassette can also be pulled out in the same way.This makes it possible to perform copying operations from the front, rear, and both sides of the apparatus.

There is no problem with pulling out the cassette in two directions, sideways and toward you, or in any direction.

As explained above, according to the configuration of the present invention, the cassette can be mounted from the left and right, front and rear, or any other arbitrary direction, which greatly increases the restrictions on where the copying machine can be installed. In addition, the cassette can be conveniently loaded from either the left or right direction, that is, by either the right hand or the left hand.
