The structure is such that the trays are stacked vertically at a predetermined distance and held in a stacked state, and each tray is held in a state that extends diagonally toward the direction in which the recording material is ejected, so the overall bulk is reduced. It has no choice but to take on a higher form,
Moreover, when the recording materials are stored in the tray, the order in which the recording materials are stacked is opposite to the page order of the original document, and when you want to compile multiple pages of recorded documents, etc., you have to stack them again, which is inconvenient. There are many things.

Particularly in recent years, medium-sized copying machines have become widely used, and there is a desire to develop a collating device for such copying machines that is compact and easy to use for the operator.

[Means for solving problems]

In order to achieve such an object, the present invention provides a means for feeding a recording material introduced from a feeding port between upper and lower guide plates to a conveying path by a feeding means, and a tray holding section disposed along the conveying path. In a collating device capable of selectively discharging to one of a plurality of fixed trays held by It is characterized by comprising a plurality of fixed trays that are held in a state of being tilted to the side, and a means for reversing the front and back of the recording material when discharging the recording material from the conveyance path to the fixed I-ray. be.

(Function) According to the collating device of the present invention, when the recording material is inserted from the feeding port, the feeding motor is driven and the recording material is fed along the conveying path having an upward slope. On the other hand, in the tray to be ejected, a guide member with a pinch roller is pulled down by a tray selection means which is interlocked with a feeding motor of the feeding means via a clutch mechanism to take in the recording material from the conveyance path. The fed recording material is held between a discharge roller with a 1-lay and a pinch roller along a guide member which is a means for reversing the recording material, and is then turned upside down and discharged onto the tray. reactor.

il [Examples] Examples of the present invention will be described below in detail and specifically based on the drawings.

First, in order to make the explanation easier to understand, the following describes a transport unit that has a transport path and a drive system for its transport means, a tray holding unit that holds individual tray bins, and a feeder that guides recording materials from a feeding port to a transport path. The entire apparatus will be described while roughly dividing it into four main mechanisms: a feeding section as a means, and a control section as a control means such as a tray selection means driven by a drive system of a conveying section.

FIG. 1 shows an embodiment of the present invention, where 1 is an outer case, 2 is a tray holding section, 3 is a conveyance section, and 1 l

A conveying path 11 that guides the recording material by a conveying means of
is configured.

Furthermore, in FIG. 1, 12A and 12B are a driving sprocket and a driven sprocket provided coaxially with the above-mentioned conveying pulley 108 and driven pulley IOB, and 13 is stretched between these sprockets +2A and 128. This is Chenherd. Thus, the chain belt 13 allows the discharge rollers 15 of the individual trays 14 held on the tray holding section 2 side to be interlocked. That is, 15A is a sprocket provided coaxially with the discharge roller 15, and these sprockets 15 are configured to be able to engage with the chain belt 13 from above, so that the feed motor 8 is driven. The discharge roller 15 is simultaneously rotated in the direction of the arrow along with the above-mentioned feed belt 6 and conveyance heald 9 via the chain belt 13, thereby making preparations for receiving the recording material.

16 is provided in each tray 14, and a discharge roller shaft ts
The guide member 17 is rotatable around the guide member 16, and the pinch roller 17 is pivotally supported by the guide member 16. These mechanisms will be explained in more detail with reference to FIG. In FIG. 2, reference numeral 18 indicates a guide roller disposed between the conveyance pulleys 10A and 108, and 19 indicates a static elimination brush attached to the guide member 16. This figure shows a state in which the recording material 20 is discharged to the first O bin, which is the closest to you, among the trays 14 with lO bins. It's being taken down.

FIG. 3 shows the structure of the tray 14. The tray 14 is configured to pivotally support a discharge roller shaft 15B with a bracket portion 14A on the entrance side, and a tray holding member 2A is further provided on a part of the bracket portion 14A as shown in FIG.
A fixing arm 14B that can be engaged with the fixing groove 2B is formed. Further, a tray 14 is located at βj of the discharge roller shaft 15B.
A part of the cover NC is provided by bending the end of the cover into an inverted U shape. Thus, the accidental tray 14 becomes the fixed arm 14.
B is inserted into the fixing groove 2B of the tray holding member 2 to be locked and fixed. Furthermore, a guide member 16 as shown in FIGS. 58 and 5B is pivotally supported on this discharge roller shaft 15B. Ru.

Note that in FIG. 5B, the guide member 16 is connected to the roller shaft 15B.
As seen from the side, notches 18A are formed in the guide member 16, which has a circular arc-shaped surface, at positions corresponding to the conveyor belt 9, respectively. Further, a rotary arm 16B having a roller attached to its tip is provided at the shaft support to the roller IFII 115B provided at one end of the guide member 16, and the rotating arm 16B is provided with a rotating arm 16B having a roller attached to its tip. By rotating the rotating arm 16B in the direction of the arrow, the guide member 16 is lowered to the state shown in FIG. 5A.

Furthermore, the state in which the guide member 16 is not pulled down in this way and is held in a position retracted from the transport path +1, that is, the state of the guide member 16 in the trays 14 other than the first O bin in FIG. 2 is not correct. This is achieved by the illustrated spring member, and therefore, when being lowered, the rotating arm 16B is rotated against the spring force of this spring member.

Next, details of the conveying section 3 will be explained with reference to FIG.

32 is a common drive shaft that drives the pulley 7, IO, and sprocket 12A, and the feed motor 8 rotates the common drive @32 via the timing belt 33 and the drive gear 34, and the shaft is inserted from the feed port 4. The recorded recording material can be transmitted from the feeding belt 6 to the conveying belt 9 of the conveying path 11. Also, this common it! A one-way clutch cam 35 and a small gear 368 are disposed on the li+32, and a solenoid 37 having a lever 37A that can be engaged with a locking surface of the cam 35 is provided below the cam 35.

35B is a large gear that meshes with small gear 368; 36C is a switch operating cam provided coaxially with large gear 36B;
A timing belt 8 is driven in the direction of the arrow through a large gear 36B, and the timing belt 38 allows the tray selection cam member 31 to be moved.

39 is a microswitch that is turned off by an operating cam 36C when the large gear 36B rotates once, and 40 is a microswitch for detecting the position of the first bin.

Next, referring to FIG. 7, a description will be given of a sensor that monitors the operation until the recording material is discharged onto the tray 14. Here, 51 is a first sensor that detects that the recording material is guided to the feeding port 4, and 51A is an actuating piece thereof that projects from the lower guide plate 5B toward the feeding port 4. That is,
When the recording material is inserted into the supply port 4 in the first sensor 51,
When the operating piece 518 is tilted, its state is detected optically, for example, and the feeding motor 8 is driven to guide the recording material 20 to the conveying path 11 by the feeding belt 6 and the conveying belt 9.

In addition, if the actuating piece 51A of the first sensor 51 does not return to its original state even after the time has elapsed for the recording material 20 to be completely guided to the conveyance path 11, the control section It is determined that a jam has occurred, and the motor 8 can be stopped.

52^ and 52B are a light emitting part and a light receiving part of a second sensor respectively arranged on the population side and the exit side along the conveyance path 11;
This is the optical path to B. Note that this optical path 53 is illuminated by the recording material 20 only while the recording material 20 is guided from the transport path 11 to the tray 14 while being reversed by the guide member 16, as shown in this figure. The light emitting section 52A and the light receiving section 52B are attached relative to each other so that the recording material 20 does not exist on the conveyance path 11, or even if it does exist, it is not taken into either tray 14 during conveyance. During the process, the optical path 53 is not blocked.

In this way, the second sensor monitors the period from when the recording material 20 begins to be discharged to one of the trays 14 until it is completely discharged, and if this time is longer than a predetermined time set in advance, the control section The tray 14 is placed in the middle of the path 11 or in relation to the discharge roller 15, the guide member 16, etc.
It is determined that a jam has occurred while the paper is being completely ejected, and the motor 8 can be stopped.

Furthermore, the recording material 20 is moved to the tray 14 by the second sensor.
When it is detected that the recording material 20 has been ejected to the next tray 14, the control section can operate the guide member 16 with the tray by the tray selection means described above so that the recording material 20 is ejected to the next tray 14.

That is, when it is determined that the recording material 2o has been ejected to one of the trays 14, the solenoid 37 is energized as shown in FIG. linked by
The selection cam member 31 is moved in the direction of the arrow. Thus,
When the cam member 31 rotates the rotation l191i16B of the guide member 16 at a position corresponding to the next tray 14 and lowers the guide member 16 to the state shown in FIG. 5A, the microswitch 39 turns the solenoid 37 can be turned off and ready to receive the next recording material.

FIG. 8 shows a circuit configuration for implementing the above operation,
Here, 41 is a control section, 42 is a power supply section, and 43 is an operation display section, and since these are commonly used in this type of collating device, their explanation will be omitted. Now, referring to FIG. 9, the timing at which the control section executes the series of operations described above is as follows: First, in (A>), when the first sensor 51 detects the recording material and enters the "on-pa" state, , (B), the feed motor 8 is driven.

Thus, in the first sensor 51, the recording material is transferred to the conveyance path 11.
If it is fed in the direction of , the feed motor 8 is turned off, but if it does not turn off after a predetermined period of time, it is assumed that a jam has occurred, and the drive of the feed motor 8 is stopped at fc). be done.

The recording material is then monitored by the second sensor 52, and when the recording material begins to be taken into the selected tray 14, the second sensor 52 becomes "on" in (B), and the taking-in or end is in the "off" state. However, as shown in (C), the feed motor 8 is still in the driving state and is in the deaf state, and when the second sensor 52 in the roller section 41 becomes "active," As shown in (D), the clutch solenoid 37 is turned on, the cam member 31 is advanced, and when the switching to the next bin is completed, the clutch solenoid 3 is turned off.

Further, in (B), if the second sensor 52 does not become obstructed even after a predetermined period of time has elapsed, it is determined that a jam has occurred, and the drive of the feed motor 8 is stopped in (C). .

Thereafter, each time recording materials are taken in from the feed port 4, the collating operation is performed at the timing described above.

It goes without saying that by selecting the mode in the control section 41, it is possible to continuously discharge recording materials to the same tray without operating the tray selection means.

Furthermore, in FIG. 7, the portion forming the conveyance path 11, that is, the conveyance section 3 shown in FIG. They are integrally constructed through a support frame, and in the event of a jam, the position shown by the two-dot chain line can be moved by releasing the locking part provided on the left side in Figure 7. It can be easily lowered to.

Further, a feeding mechanism (shown surrounded by a broken line) 54 including the upper guide plate 5A, the lower guide plate 5B, and a feeding means using the feed belt 6 is also rotatable around the common drive @32A. Therefore, it is possible to appropriately adjust the height of the feeding port.

FIG. 1O shows the structure of a conveyance section 3 according to another embodiment of the present invention, and is a part of the structure shown in FIG. 6, which corresponds to the conveyance path 11. In order to make the explanation easier to understand, parts of the discharge roller 15 and the roller pongee 15B provided on the tray side are shown separated from the tray side. In this example, 61 is a thin wire made of steel or resin, and in the example shown in FIG. The belts 9 and their driving means located on both sides of the book transport heald 9 are eliminated, and instead of stiff wires, two thin wires 61 are stretched.

Further, 62 is a support rod provided to hold these thin wires 61 at the same height as the upper surface of the conveyor belt 9 and maintain an accurate pitch between them, and 63 is a support rod that maintains tension on the thin wires 61. Thus, one end of the coil spring 61 is fixed to the fixed frame 64 via the coil spring 63, and the other end is fixed to the fixed frame 64.

In the conveyance section 3 configured in this way, when the recording material is guided onto the conveyance path 11 by a feed belt (not shown),
It can be transported by the conveyor belt 9 disposed in the center with both ends smoothly supported by a plurality of thin wires 61, and as the number of conveyor belts 9 is reduced, the structure is simplified and the cost is low. I will make a sincere contribution.

〔Effect of the invention〕

As explained above, according to the present invention, the recording material guided from the feeding port between the upper and lower guide plates is conveyed by the feeding means and supplied to the path, and the tray holding device provided along the conveying path is provided. In the T-metal device that can selectively discharge one of the plurality of trays held in parallel in the tray from the conveyance path, the conveyance path and the tray holding part are maintained at an upward slope and are parallel to each other. A plurality of trays that are maintained at a high level are arranged by tilting them on the opposite side of the above-mentioned upward slope. Therefore, the entire device is compact without being bulky, making it easy to carry and handle. It is possible to provide a T-gage device that is not only convenient, but also allows recording materials to be stored with the front and back sides reversed, and is easy to use for the handler.

Furthermore, since the feeding means and the conveyance means constituting the conveyance path are driven by a common drive shaft, and the conveyance path is rotatable around this common drive shaft, the conveyance path can be made almost horizontal. By rotating the recording material to this position, the recording material can be separated from the tray holding section, and the recording material can be removed very easily during inspection or when a jam occurs. Further, by making the feeding means including the upper and lower guide plates rotatable around the common drive shaft, it is possible to appropriately change or adjust the vertical position of the feeding port.
