Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an image forming apparatus such as a copying machine or a laser beam printer.

(CD) Conventional technology In image forming apparatuses such as copying machines, small and low-speed types, as shown in FIG. will be provided. In addition, in the case of such a small, low-speed type image forming device,
The device main body 1 is divided into two parts, and the upper device main body 1a is divided into T
In most cases, the I'lE device main body [B] and the paper discharge side end [C] are connected so that they can be opened and closed in the direction of the F element (in the direction of the arrow) around the rotation center.

In this way, by opening the north device main body Is as shown in the imaginary line, it is possible to easily remove paper jams that have formed inside the lower device main body [b], resulting in excellent handling efficiency in the event of a paper jam. It is. In this case, the paper discharge tray 2 has conventionally been rotatably attached to the lower apparatus main body 1b.

(C) Invention or Problem to be Solved However, when the paper output tray 2 is attached to the lower device main body ib as in the above-mentioned conventional case, it is necessary to clear the paper jam that occurs on the paper output side (copy 0). In order to do this, the paper ejection cover 3 cannot be opened unless the paper ejection tray 2 is removed from the preparation main body 1b as shown in FIG. 12 each time. Therefore, it is difficult to deal with paper jams on the paper discharge side.

Therefore, as a measure to eliminate such inconvenience, as shown in FIG. 13, the ejected paper stacking position relative to the lower apparatus body 1b (the attitude of the ejected paper tray 2 in Fig. 11) and the position relative to the upper apparatus main body 1a are changed. A structure may be considered in which a paper discharge tray 2 whose storage position (the position shown in the figure) can be rotated is attached to the upper apparatus main body 1a. In this structure, when the paper ejection tray 2 is switched from the ejected paper stacking position to the storage position, the outer surface portion of the lower apparatus main body 1b is opened, so that there is no need to remove the paper ejection tray 2 from the apparatus main body 1 as shown in the figure. The paper discharge cover 3 can be opened as shown in FIG.

Note that the paper discharge tray 2 can be rotated in the vertical direction about its base 2a, and when it is rotated upwardly, it assumes the storage position, and when it is rotated downwardly, it assumes the discharged paper stacking position. Further, the illustrated paper ejection tray 2 consists of a first tray 2b and a second tray 2C rotatably coupled to the first tray 2b, and in the stored position, the second tray 2C is relative to the first tray 2b. It is bent as shown in the figure, and the second
The tray 2C is in a horizontal state with respect to the first tray 2b.

However, with this structure, there is no problem when the upper device main body 1a is idle even when the paper output tray 2 is in the retracted position. When the upper apparatus main body 1a is opened as shown in FIG. 13 with the paper output tray 2 in the retracted position to clear a jam, etc., the paper output tray 2 in the retracted position rotates around the base 2a as shown by the arrow. As a result, not only does the storage position collapse, but also the problem of interfering with the opened paper ejection cover 3 arises.

The present invention has been made in view of the above-mentioned circumstances, and even if the upper device main body is opened while the discharged paper stacking means is in the retracted position, the discharged paper stacking means can maintain that state without losing its retracted position. It is an object of the present invention to provide an image forming apparatus which is configured as follows.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention divides the device main body (1) into upper and lower parts, as shown in FIGS. 1 and 4, and (1a) to the lower device body (1b)
), in which the image forming apparatus is coupled to the upper device main body (1a) and the lower device main body (1b) so that the paper ejecting side end (1c) can be opened and closed in the vertical direction about the rotation center. A discharged paper stacking means (2) that is rotatably switchable between a loading posture and a storage posture with respect to the upper apparatus main body (1a) is attached, and the discharged paper stack that has been switched to the storage posture is attached to the upper apparatus main body (1a). The device is characterized in that it is provided with storage posture holding means (5) for holding the means (2).

(f) Effect According to the above configuration, when the ejected paper stacking means (2) is placed in the retracted position, the retracted position is maintained by the retracted position holding means (5) provided on the upper apparatus main body (1a). Therefore, even if the upper device main body (1a) is opened, the ejected paper stacking means (2
) will not collapse.

Note that the above-mentioned symbols in parentheses are used to refer to the drawings, and do not limit the answer structure.

(f) Example Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows an image forming apparatus according to an embodiment of the present invention.

They are connected so that they can be opened and closed in the vertical direction (in the direction of the arrow) with C as the rotation center. The figure shows a state in which the upper device main body 1a is opened upward.

A paper discharge tray 2 is attached to the upper apparatus main body 1a and is rotatably switchable between a discharge paper stacking position with respect to the lower apparatus main body 1b and a storage position with respect to the upper apparatus main body 1a. The figure shows a state in which the paper discharge tray 2 is in the retracted position. Further, the upper apparatus main body 1a is provided with a plurality of storage position holding bins 5 that hold the paper discharge trays 2 that have been switched to the storage position.

1. A first tray 2b is connected to the side device main body 1a so as to be able to rotate about a connection point 6, and the connection point 7 is connected to the first tray 2b.
] The second tray 2c is connected to the rotary opening T function in the middle movement. FIG. 2 shows a state in which the first tray 2b is rotating about the coupling point 6. As shown in FIG. Also, the third
The figure shows a state in which the second tray 2C is rotating about the connection point 7. Such a paper discharge tray 2 can be placed in the storage position by rotating it upward with the connecting point 6 of the first tray 2b as the center of rotation. in this case,
As shown in FIG. 1, the second tray 2C is rotated inward about the coupling point 7 and bent at a substantially right angle with respect to the first tray 2b. In this way, as shown in FIG. It is fitted into .5. Therefore, even if the L-side loading main body 1a is opened by force as shown in Fig. 1, the ejected paper 1...ray 2 in the stored state will maintain its stored state without collapsing. When the paper ejection tray 2 is placed in the retracted position in this way, the lower device main body 1b
The paper ejection cover 3 provided on the machine can be opened in the direction of the arrow. Further, the paper discharge tray 2 can be changed to the discharge paper stacking position by rotating the connecting point 6 of the first tray A 2b in the direction F around the center of rotation. In this case, the second tray 2C is replaced with the first tray 2b as shown in the first part of FIG.
