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 the sensor that monitors the operation until the recording material is discharged onto the tray 1'14.

Here, 51 is a first sensor that detects that the fl material is guided to the feeding port 4, and 51A is a lower guide plate 5B.
This is the actuating piece that protrudes from the feed port 4 side. That is, when the recording material is inserted into the supply port 4, the first sensor 51 detects the state optically, for example, by tilting its operating piece 51A, and drives the feed motor 8 to move the feed belt. The recording material 20 is guided to a conveyance path 11 by a conveyor belt 9 and a conveyor belt 9 .

Further, if the operating piece 51A of the first sensor 51 does not return to its original state even after the time period until the recording material 20 is completely guided to the conveyance path 11, the controller controls the operation of the conveyance path I11.
: It is determined that a jam has occurred during the guide, and the motor 8 can be stopped.

Reference numerals 528 and 52B are a light emitting part and a light receiving part of a second sensor disposed along the conveyance path 11 on the population side and the exit side, respectively, and 53 is a light emitting part and a light receiving part of a second sensor disposed along the conveyance path 11, and 53 is a light receiving part 52 from the light emitting part 52A.
This is the optical path to B. Note that this optical path 53 is shaded 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 the figure. The relative positions of the light emitting section 52A and the light receiving section 52B are set as shown in FIG. During the process, the optical path 53 is not illuminated.

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 or the tray 14 is detected 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 tray guide member 16 using 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 20 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 rotating arm 1BB 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 closes the solenoid. 37 can be deenergized 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 the 9th
Describing the timing when the control section executes the series of operations described above with reference to the figures, first, in (A), when the first sensor 51 detects the recording material and becomes "on", in (8) The feed motor 8 is driven.

Thus, in the first sensor 51, the recording material is transferred to the conveyance path i1.
If the ZM is fed, 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 in (C). Ru.

Next, the recording material is monitored by the second sensor 52, and when the recording material starts to be taken into the selected tray 14, (B)
The second sensor 52 enters the "on" state, and becomes the "off" state when the intake is completed; however, the feed motor 8 is still in the driving state as shown in (C), and the control unit 41
Then, when the second sensor 52 turns OFF, the Claratin Renoite 37 is turned on as shown in FIG. Claratin Lenoit 37 was completed when
becomes °゛ob゛.

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

Thereafter, each time a recording material is taken in from the feed port 4, the collating operation is carried out at the above-mentioned timing L3.

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 feeding means by the feed belt 6 also rotates around the common drive @32A. Therefore, it is possible to appropriately adjust the height of the feeding port.

FIG. 10 shows the configuration of a conveying section 3 according to another embodiment of the present invention, which is a part of the structure shown in FIG. 6 that corresponds to the conveying path 11. In order to make the explanation easier to understand, parts of the discharge roller 15 and the roller glaze 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 healds 9 and their driving means located on both sides of the book conveying belt 9 are eliminated, and in their place 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 thin wire! 5.61 is a coil spring for maintaining tension, and 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 as it is.

In the conveyance unit 3 configured in this way, when the recording material is guided onto the conveyance path ll 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 costs are reduced. will also contribute.

(Effects of the Invention) As described above, according to the present invention, the recording material guided from the feeding port to the conveying means by the feeding means is transferred to one of a plurality of fixed trays arranged along the conveying means. In a T-coupling device capable of discharging toilets using a single discharging roller, the discharging rollers provided in each toilet are driven together with a feeding means and a discharging means by one driving source via one common drive shaft. Therefore, not only is the overall structure compact, but it also has a common drive! The feeding means, the unloading means, and the ejection roller driving means can each be configured to be rotatable as a unit around the axis of the IJiIII], and the vertical height of the feeding port can be adjusted by rotating the feeding means. In addition, the rotation of the conveying means and ejection roller drive means not only makes it easy to remove the recording material in the event of a jam, but it is also convenient for maintenance and inspection, making it convenient for the operator. It is possible to provide an easy-to-use T-coupling device.
