Abstract

PURPOSE:To make a paper feed position empty and to make it possible to mount and remove a paper feed cassette, separately, by arranging a paper feed container, rotatably and movably between a paper feed position on one side surface of a paper feed device and a paper replenishing position on the front surface of the device. CONSTITUTION:When a paper feed container 10 is set at a paper feed position, an inclined surface y1 of a cam section 12c abuts against a release pin 75, and therefore it pushes up a pick-up roller 30 together with a frame 71. When the container 10 is completely set, the release pin 75 falls into an inclined surface y2 so that the pick-up roller 30 makes into press-contact with the upper surface of stacked paper sheets P by its dead weight. When the paper container 10 is moved away from the paper feed position, it is reversed. When the paper feed container 10 is started to rotate and move from the paper feed position to the paper replenishing position, the rotation of the container 10 causes the pick-up roller 30 to be raised to a some degree. Therefore, when the paper feed container 10 is moved away from the paper feed position, the pick-up roller 30 is surely separated from the uppermost one of the stacked paper sheets P, thereby it is possible to prevent the uppermost paper sheet P from adhering to the pick-up roller so that it is left alone.

On the other hand, in this type of paper feeding device, the paper feeding container can be rotated between the paper feeding position on the side of the device and the paper hff feeding position on the front of the device, in order to make it possible to perform Nlt feeding of paper at the front of the device. A movable installation has been proposed (Japanese Unexamined Patent Publication No. 5
(See Publication No. 9-167423). In this case, the paper feed container itself is removably mounted on a rotatable table, and the paper feed container itself containing different types of paper can be replaced.

Means for Solving the Problems Therefore, the paper feeding device according to the present invention not only employs the paper feeding container rotation method, but also provides a mechanism for rotating the paper feeding container from the paper feeding position to the paper replenishing position. It is characterized by a removable paper feed cassette at the paper feed position.

In other words, when the paper feed container is rotated to the paper replenishment position, the paper feed position becomes empty, and by making it possible to attach and detach a separate paper feed cassette to that paper feed position, the regular paper feed container itself becomes empty. This allows the paper to be replaced without the need for attachment/detachment work.

Paper feeding is carried out by rotating the pickup rollers (30) of each stage selected in advance by the operator on the copying machine (1) side, so that the paper (P) is sent out from the top layer in the direction of the arrow (A). The sheets are sorted one by one by the cutting means (32), and those in the upper stage are passed through the conveyance roller (35a), and those in the middle stage are separated from the conveyance roller (35b) to the conveyance roller (35).
In the case of the lower stage, the transfer is performed from the conveyance roller (35c) to the conveyance rollers (35b) and (35a) through a). One sheet of paper (P
) is fed into a paper supply unit adapter (40) described below, and is conveyed to a transfer unit (not shown) by conveyance rollers (46), (2) and a pair of conveyance rollers (3).

In the above configuration, when the final stage reduction gear (57c) meshes with the sector gear (50) and pushes up the bottom plate (19) with the push-up arm (3I), the push-up arm (31)
The weight of the paper (P) and the bottom plate (I9) acts on the , and this load acts as a force to return the fan-shaped gear (50) in the direction of the arrow (a), and the gap between it and the final stage reduction gear (57c) is There is a risk that so-called tooth skipping may occur. However, in this embodiment, the meshing position of the sector gear (50) and the reduction gear (57c) is between the support shaft (51) of the sector gear (50) and the support shaft (28) of the plate (53). , and the meshing relationship between the two is such that the final stage reduction gear (57c) is biased in the direction of meshing with the sector gear (50) under a load that rotates the sector gear (50) in the direction of arrow (a). Since the structure is such that the teeth are not skipped, tooth skipping does not occur. This means that when the two are engaged, the push-up unit (52) is always subjected to an urging force in the direction opposite to the arrow (a) using the support shaft (28) as a fulcrum, and the push-up unit (52) maintains the engaged state. Therefore, it is not necessary to bias the push-up unit (52) in the direction opposite to the arrow (a) by means such as a spring, and the leaf spring (17)
The pin (55) comes into contact with the pin (55) only when the reduction gear (57c) is engaged with the sector gear (50), and after the engagement, the pin (55) is separated from the leaf spring (17). In addition, when the push-up unit (52) is separated from the paper feed container (!0) and the paper feed position, the pin (55) is urged downward by the cam plate (16) and then the push-up unit (52) is attached to the plate (53). ) is the stopper (
60), rotates in the direction of arrow (a) by its own weight until it comes into contact with 60). Therefore, when the paper feed container (10) is attached to and removed from the paper feed position, the force that operates the push-up unit (52) is only the force that causes the push-up unit (52) to rotate in the vicinity of a substantially vertical position. Hopefully, it will be reduced considerably.

In addition, the sector gear (50) of the final stage reduction gear (57c)
In order to ensure the engagement with the spring and further reduce the rotational force of the push-up unit (52) caused by the temporary spring (17),
The push-up unit (52) itself is moved by the arrow (a) by the spring means.
It is also possible to apply a slight force in the opposite direction.

On the other hand, a cam portion (12c) formed at the tip of the side plate (12) of the paper feed container (lO) can be engaged with the release bin (75) fixed to the rear side of the frame (71), and this cam The portion (12c) has a chevron shape with inclined surfaces (y, ) and (y-). That is, when the paper feed container (10) is set at the paper feed position, first the inclined surface (
y,) comes into contact with the release pin (75) and the frame (7I)
and push up the pickup roller (30) (No. 13a)
When the release pin (75) is completely set, the release pin (75) falls onto the inclined surface (y2), and the pickup roller (30) comes into pressure contact with the top surface of the paper (P) due to its own weight (see Figure 13b). (See Figure 13c). When the paper feed container (10) leaves the paper feed position, contrary to the above, first the cam part (
The inclined surface (y2) of 12c) comes into contact with the release pin (75) and the pickup roller (30) together with the frame (71)
(see Fig. 13c → Fig. 13b), and then the release bottle (75) falls down along the slope (y2), and the pickup roller (30) pushes up the protrusion (7) of the frame (71).
1a) moves downward until it comes into contact with the stopper piece (39a) (see Figure 13a).
