FIG. 4 is a perspective view of the upper part of the electrostatic copying machine shown in FIG. 1, viewed from behind. A locking member 16 is provided at the upper part of the body 1 and extends along the copy paper discharge direction 10. One end of this locking member 16 is located in the paper discharge direction 1.
It is pivoted to the fuselage 1 via a horizontal pin 17 that is perpendicular to 0. A guide hole 18 extending vertically is formed in the upper part of the side portion 1a of the body 1, and the other end of the locking member 16 projects outward from the guide hole 18. A hook-shaped locking portion 19 is formed at the other end of the locking member 16 . This locking portion 19 is formed with an inclined abutment portion 19a that is inclined downward toward the lower side along the paper discharge direction 10.

In the middle of the locking member 16, there is a pressing part 2 extending upward.

The hole 21 is formed on the rear side (left side in FIG. 4) of the document holding member 3. Further, a lower end portion of a spring 22 extending vertically is connected to the middle of the locking member 16, and an upper end portion of the spring 22 is connected to a fixed position of the body 1. Therefore, the locking member 16 moves around the pin 17 in the direction indicated by the arrow 23 due to the spring force of the spring 22, that is, in the direction in which the pressing part 20 projects upward from the hole 21, and the locking part 19 moves around the guide hole 18. It is biased in the direction of being located at the top.

The rear end (left side in FIG. 4) of the document holding member 3 is pivotally supported on the body 1 so as to be rotatable around an axis 24 parallel to the paper discharge direction 10. A pressing portion 2 is provided on the rear side (left side in FIG. 4) of the document holding member 3.
A pressing surface 25 that can come into contact with 0 is formed. When the document holding member 3 is rotated in the direction of the arrow 26 in order to hold down the document on the document table (not shown), the pressing surface 25 comes into contact with the pressing portion 20, and the pressing portion 20 is thereby pressed downward. Can be lowered. As the pressing portion 20 is pushed downward in this manner, the locking member 16 rotates in the direction opposite to the direction indicated by the arrow 23 against the spring force of the spring 22, and the locking portion 19 rotates in the direction opposite to the direction indicated by the arrow 23. is driven from the top to the bottom of the guide hole 18.

Referring again to FIGS. 2 and 3, a buffer means 27 is interposed between one end 8a of one side plate 8 of the copy receiving member 4 and a fixed position above the one end 8a. be done. Further, an abutment member 28 is fixed to the inner surface of the side portion 1a of the copy receiving member 4 at an upper position corresponding to one end portion 9a of the other side plate 9. Further, the paper ejection direction 10 of the copy receiving member 4 is
An engaging portion 29 that can engage with the locking portion 19 of the locking member 16 is formed at the other end on the lower side along the .

FIG. 5 is a sectional view of the buffer means 27. The buffer means 27 includes a cylindrical body 30 connected to the body 1, a valve body 31 provided at one end of the cylindrical body 30 (upper part in FIG. 5), and a copy receiving member fitted into the cylindrical body 30 from the other end. 4 and a cylindrical rod member 32 connected to the cylindrical rod member 32. A support member 33 is fixed to the cylindrical body 30, and this support member 33 is pivotally supported by a support shaft 34 extending parallel to the shafts 13 and 14. This support shaft 3
4 is fixed to the fuselage 1. The rod member 32 is connected to one end 8 a of the side plate 8 of the copy receiving member 4 via a pin 35 parallel to the support shaft 34 .

The valve body 31 has a pin 36 perpendicular to the axis of the cylinder body 30.
It can be rotated freely. Moreover, the valve body 31 is only allowed to rotate in the direction shown by the arrow 38 from the state shown in FIG. Further, a small diameter communication hole 37 is formed in the valve body 31 . Inner wall of cylinder 30 and rod member 32
The volume of the air chamber 39 defined by the rod member 32 is
It changes depending on the axial displacement of. When the copy receiving member 4 rotates in the opposite direction of the arrow 5, the rod member 32 is displaced downward in FIG. Accompanying this, the volume of the air chamber 39 increases to a negative pressure as shown in FIG. 6, and the valve body 31 accordingly rotates in the direction of the arrow 38 and opens. Therefore, air can freely flow into the air chamber 39, and the rod member 32 is displaced downward in FIG.
Rotation in the opposite direction is performed smoothly.

Contrary to the above, it is assumed that the copy receiving member 4 rotates in the direction indicated by the arrow 5. In this case, the rod member 32 is displaced upward in FIG. As a result, the volume of the air chamber becomes smaller, and the sixth
As shown in FIG. 2, the valve body 31 rotates in the opposite direction to the arrow 38 and closes. Therefore, the air that should be discharged as the volume of the air chamber 39 decreases is discharged from the circulation hole 37. Furthermore, since the flow hole 37 has a small diameter, the amount of air discharged from the flow hole 37 is limited to a small amount, and therefore, the upward displacement speed of the rod member 32 in FIG. 5 is limited. Therefore, the rotational speed of the copy receiving member 4 in the direction indicated by the arrow 5 is limited to a low speed.

Next, the operation of the copy receiving apparatus configured as described above will be explained. During copying, the copy receiving member 4 is moved as shown in FIGS. 2 and 3.
The drawer is drawn out in a substantially horizontal position so that it can receive copied paper. After the copying operation is completed and the original is removed from the original table, the copy receiving member 4 is held and rotated upward in the direction opposite to the arrow 5. At this time, the engaging portion 29 of the copy receiving member 4 comes into contact with the inclined contact portion 19a, so that the locking member 16 is rotated in the direction opposite to the arrow 23 against the spring force of the spring 22. Therefore, when the locking portion 19 descends and the inclined contact portion 19a and the engaging portion 29 come out of contact, the locking portion 19 rises and engages with the engaging portion 29. Thereby, the folded position of the copy receiving member 4 is maintained as shown in FIG.

In this folded position, the center of gravity of the copy receiving member 4 is aligned with the axes 13 and 14 along the paper ejection direction 10.
Therefore, when the engaging portion 29 and the locking portion 19 are disengaged, the copy receiving member 4 moves in the direction indicated by the arrow 5 due to its own weight. Rotate to.

When the document holding member 3 is released in order to place the document on the document table for copying again, the pressing surface 25 comes into contact with the pressing portion 20. Thereby, the locking member 16 rotates downward around the pin 17, and the locking portion 19 is accordingly displaced downward along the guide hole 18. Therefore, the engagement between the locking portion 19 and the engaging portion 29 is disengaged, and the copy receiving member 4 begins to rotate in the direction shown by the arrow 5 due to its own weight. The downward rotation of the copy receiving member 4 is limited to a low speed by the buffer means 27, as described above. Therefore, the copy receiving member 4 is prevented from rotating rapidly and colliding with the lower part of the paper ejection port 6. Therefore, generation of impact noise and damage to various parts due to a collision can be avoided.

The rotational movement of the copy receiving member 4 in the direction indicated by the arrow 5 is restricted by the one end 9a of the side plate 9 coming into contact with the abutting member 28. This contact member 28
The copied copy paper is discharged onto the copy receiving member 4 in the pulled-out position in which the and one end portion 9a are in contact with each other.

As another embodiment of the present invention, the rod member 32 of the buffer means 27 is connected to the support shaft 34, and the cylindrical body 30
may be connected to the copy receiving member 4, and the valve body 31 may be configured to open only when the volume of the air chamber 39 decreases.

In addition, as another embodiment of the present invention, the locking portion 19
The engagement state between the engagement portion 29 and the engagement portion 29 may be released by pressing a print button (not shown). For example, the locking member 1 is
6 may be rotated in the opposite direction to the arrow 23 against the spring force of the spring 22. Further, in response to the operation of an optical system (not shown), the locking member 16 is moved to the arrow 2.
3 may be rotated in the opposite direction.

FIG. 7 is a sectional view of another embodiment of the present invention.
A locking member 40 that can be engaged with the engaging portion 29 of the copy receiving member 4 is pivotally supported by a pin 41 that is parallel to the shafts 13 and 14. This locking member 40 is rotationally biased by a spring 42 in a direction in which it engages with the engaging portion 29 .
Also in this embodiment, the folded posture of the copy receiving member 4 can be maintained. To change the copy receiving member 4 from the folded position to the pulled-out position, the copy receiving member 4 may be manually rotated.

Furthermore, as shown in FIG. 8, a magnetic body 43 such as an iron piece is fixed to either the copy receiving member 4 or the side 1a of the machine body 1, and a magnet 44 is attached at a position corresponding to the other magnetic body 43. Even by fixing, the folded posture of the copy receiving member 4 can be maintained. In this case, a press bar 45 that comes into contact with the upper part of the copy receiving member 4 in the folded position is provided so as to be movable in parallel to the copy paper ejection direction 10, and the press bar 45 is pressed in the direction of the arrow 46. The folded position of the copy receiving member 4 may be released. This pressure rod 4
5 is biased in the pressing direction 46 by a spring 47. A locking portion 48 is formed in the middle of the pressing rod 45, and the pressing rod 45 is engaged with the locking portion 48.
a claw 49 for preventing displacement in the direction of arrow 46;
is provided. Note that the locking portion 48 and the pawl 49 are not engaged when the pressing rod 45 is pushed in the direction opposite to the arrow 46 by the copy receiving member 4, and the copy receiving member 4 is in the folded position as shown in FIG. is configured to engage when the To release the folded position of the copy receiving member,
The claw 49 may be moved away from the locking portion 48 in conjunction with the copying operation or the opening operation of the document holding member 3. Then, the pressing rod 45 moves the copy receiving member 4 at the arrow mark 4 by the spring force of the spring 47.
6, the coupling between the magnetic body 43 and the magnet 44 is released, and the copy receiving member 4
becomes the pulling position.

FIG. 9 is a perspective view of another embodiment of the present invention.
The copy receiving member 4 may be stored in a storage portion 50 formed in the side portion 1a of the body 1 in its folded position. In this case, the storage section 50 is designed to prevent outside light from entering the inside of the aircraft 1.
It must be isolated from the inside.

As described above, according to the present invention, the copy receiving member can be placed in a folded position in close contact with the machine body, which is convenient because the space occupied by the copy receiving member is freed up when the copying machine is not in use. In addition, when packing, the copy receiving member can be packaged integrally with the machine body, so there is no need for a case for the copy receiving member as in the past, and there is no inconvenience such as forgetting to pack the copy receiving member. It will be resolved. In particular, in the present invention, the means for maintaining the folded position of the copy receiving member is configured to release the folded position in conjunction with an operation related to copying, such as an opening operation of a document holding member or a copying operation of a copying machine. Therefore, during copying, the copy receiver is drawn out in a substantially horizontal position connected to the paper ejection slot. Therefore, the copy paper after copying is reliably received by the copy receiver from the paper ejection slot. Therefore, the copy paper is prevented from colliding with the copy receiver and causing a paper jam, or from falling onto the floor.
