Is loaded.

In the above configuration, the sheet discharged from the sheet discharge section of the sheet processing apparatus travels along the sheet discharge path. When the sheet reaches the stop guide plate, the sheet is rebounded toward the sheet discharge section and falls on the slope of the sheet receiving table. It is loaded on the slope.

According to the above configuration, since the slope is lower on the side of the horizontal guide plate, the paper slides toward the horizontal guide plate, and the edge of the paper hits the horizontal guide plate. As a result, the sheets are aligned along the horizontal guide plate. Therefore, the sheets can be satisfactorily aligned and stacked.

Further, the lateral guide plate is disposed only on one side in the direction crossing the paper discharge path, and there is no lateral guide plate on the other side which hinders sheet removal. Therefore, the paper loaded on the paper receiving table can be easily taken out.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a paper receiving apparatus according to each embodiment of the present invention will be described with reference to FIGS.

First, an envelope content discriminating apparatus using a paper receiving apparatus according to a first embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to FIG.

The envelope content discriminating device is a device for inspecting the thickness of the double envelope in which the absentee ballot is put and opening the double envelope.

The voting paper, the inner envelope, and the outer envelope for absentee voting are all formed of a paper material having a specified shape and a specified thickness. It has a constant thickness. For example, if there are two ballots, or an inner envelope without a ballot is in an outer envelope, the thickness of such double envelopes will be It is thicker or thinner than the double envelope. Therefore, by inspecting the thickness of the double envelope, it is possible to determine whether the envelope is appropriate or inappropriate without opening and examining the contents. In addition, for example, in the case of a large number of mails in which a prescribed number of sheets are placed in a prescribed envelope, such as a commercial direct mail, by inspecting the thickness of each envelope,
It is possible to determine whether the product is acceptable or unacceptable.

The envelope content discriminating apparatus is configured as shown in FIG. In the figure, reference numeral 10 denotes an entrance hopper section on which double envelopes 2a to be subjected to processing such as content discrimination processing are loaded. Reference numeral 11 denotes a separating unit that separates the double envelopes 2a one by one and sends out the double envelopes 2a to the envelope transport path 18. Reference numeral 12 denotes a first transport roller pair that transports the double envelope 2b. 13 is
A thickness detecting unit that detects the thickness of the double envelope, and determines whether or not one voting sheet is properly contained in the double envelope, and further, determines whether or not the envelope is multi-fed, and determines whether or not the envelope is multi-fed. Detected from the thickness of Reference numeral 14 denotes a second transport roller pair. Reference numeral 15 denotes a slit section for cutting an opening slit into the outer envelope of the double envelope to be conveyed, and cuts the opening slit only on one side of the outer envelope. Reference numeral 16 denotes a third transport roller pair. Reference numeral 17 denotes an exit stacker unit that receives and stacks the double envelopes 2c that have been subjected to predetermined processing and that have been discharged from the paper discharge unit 16x to the outside of the apparatus main body 4, that is, a paper receiving device.

In the inlet hopper 10, the envelopes to be discriminated are aligned and placed in a stacked state. Inlet hopper 10
Is inclined so as to descend toward the transport path 18, and the double envelope 2 a placed thereon is easily slid toward the transport path 18 and easily moved. Inlet hopper 1
Below the bottom surface of 0, a front feeding roller 19 and a rear eccentric roller 20 are arranged in order to effectively feed the lowermost envelope of the placed double envelope 2a to the separating portion 11. The feed roller 19 is disposed so as to contact the front part of the envelope, is driven to rotate in the feed direction, and sends the envelope forward by friction. Since the rotation axis of the eccentric roller 20 is eccentric, the outer peripheral surface of the roller moves up and down with the rotation, and the air moves between the envelopes by contacting the rear part of the envelope and moving the envelope up and down. Prevents the envelopes from sticking together. The rotation direction of the eccentric roller 20 is the same as that of the feed roller 19, but the rotation speed of the eccentric roller 20 is preferably lower than the rotation speed of the feed roller 19, and is the same as the rotation speed of the feed roller 19 even at the maximum speed. is there.

A switch 21 for detecting the presence or absence of an envelope is provided between the front feed roller 19 and the rear eccentric roller 20.
When the arm lever protruding upward from the bottom surface is pushed downward by the envelope, the switch 21 is turned on, indicating that the envelope to be discriminated is placed in the inlet hopper section 10. Conversely, if the envelope is not in the entrance hopper 10, the arm lever projects upward and the switch 21 is turned off, indicating that the envelope to be discriminated is not placed in the entrance hopper 10.

The inlet hopper 10 feeds the lowermost envelope of the loaded double envelope 2a to the separating unit 11, so that the front feed roller 19 and the rear eccentric roller 20 are used instead of the front feed roller 19 and the eccentric roller 20 shown in FIG. Alternatively, as shown in (c), the transport belts 100 and 110 may be used. In the case of FIG. 1B, the transport belt 100 has a driving roller 102 of the same diameter,
Driven by 104. In the case of FIG. 1C, the transport belt 110 is driven by drive rollers 112 and 114 having different outer diameters. In this case, if the rear drive roller 114 is an eccentric roller supported by an eccentric shaft, similarly to the eccentric roller 20, the rear portion of the placed double envelope 2a is moved up and down, and Help air to enter, double envelope 2
a can be prevented from adhering to each other.

In front of the inlet hopper section 10, the separating section 1 is provided.
1 is provided. In the separating unit 11, a lower feed roller 22 rotating in the direction in which the envelope is sent out and an upper separating roller 23 rotating in the opposite direction face each other at an interval adjusted to a gap through which one envelope can pass. And constitute a reverse rotation handling mechanism. As described above, the reverse rotation separating mechanism using the feeding roller 22 and the separating roller 23 and the feeding roller 1 below the bottom surface of the entrance hopper section 10.
The combination of the eccentric roller 9 and the eccentric roller 20 ensures that the envelope is sent out one by one from the inlet hopper 10 and conveyed.

The thickness detecting section 13 has a movable upper roller 40 and a fixed lower roller 41 provided above and below the envelope transport path 18. Both rollers are free to rotate. The movable upper roller 40 is vertically movably supported by the thickness of the double envelope passing through the transport path 18. The support structure includes a first arm 42 that is bent substantially at a right angle.
And a second arm 43, which is pivotally supported on the distal end of the first arm 42 of the lever member 44. The lever member 44 is supported with the bending point of the first arm 42 and the second arm 43 serving as a fulcrum 45. Therefore, when the double envelope on the transport path 18 passes between the movable upper roller 40 and the fixed lower roller 41, the movable upper roller 40 moves up, and the movement causes the first arm 42 and the second arm 43 to swing. . A reflection plate 43a is provided at the tip of the second arm 43, and faces the optical reflection type displacement sensor 46, and reflects an optical signal from the sensor 46. The sensor 46 detects the distance from the reflected light to the reflector 43a. The length ratio between the first arm 42 and the second arm 43 is 1: 2.5 in this embodiment, and the displacement of the distance from the sensor 46 to the tip of the second arm 43 is the thickness of the double envelope. It is detected to be 2.5 times the height. The displacement amount can be detected with extremely high accuracy, and the displacement amount can be identified without any problem as long as the displacement amount corresponds to a normal paper thickness.

As shown in the enlarged view of the main part of FIG. 8, the thickness detecting section 13 has a structure that can be easily adjusted. FIG.
(A) is a side view of the main part, (b) is a front sectional view of the main part, (c)
FIG. 4 is a bottom sectional view of a main part.

The first member 300 is provided on the frame 6 of the apparatus main body.
Are fixed, the second member 400 is fixed to the first member 300, and the sensor 46 is fixed to the second member.

The first member 300 includes three screws 301 and 3
Fixed to frame 6 at 03,305. Screw 303,
305 is inserted into the elongated holes 302 and 304 of the first member 300, and the first member 300 can adjust the mounting angle around the screw 301 as shown by a chain line in FIG. 8A. I have. The first member 300 includes the eccentric shaft 3
10 is fixed with screws 312.

The second member 400 includes a first piece 410 and a second piece 420 bent at a right angle. First piece 410
Has an elongated hole 412 through which the eccentric shaft 310 is inserted,
Together with the member 300, it is fixed with a screw 301. The sensor 46 is fixed to the second piece 420 with a screw 46a. The second piece 420 is provided with a U-shaped notch 422,
The light emitting unit and the light receiving unit of the sensor face the detection unit of the frame 43 via the notch 422.

The mounting position of the sensor 46 is adjusted as follows.

First, screws 301, 303, 305, 31
In a state where 2 is lightly loosened, the position of the first member 300 is roughly determined, and the screws 303 and 305 are tightened to fix the first member 300 to the frame 6. At this time, the detection unit 43a and the sensor 460 are set to have a predetermined interval by using, for example, a clearance gauge.

Next, the eccentric shaft 310 is rotated, fine adjustment is performed, the screws 301 and 312 are tightened, and the second member 400 is moved to the first position.
It is fixed on the member 300. At this time, an operation button (not shown) is operated to change the operation mode of the apparatus from the normal mode to the serviceman mode, and fine adjustment is performed so that the sensor output displayed on the liquid crystal display unit (not shown) becomes a predetermined value.

The slit section 15 has a disk-shaped rotary blade 50 and a fixed pressing roller 51 provided vertically above and below the envelope transport path 18. The rotary blade 50 and the fixed pressing roller 51 are both rotationally driven.

The rotary blade 50 does not cut the outer envelope of the double envelope 2b on both sides, but makes contact with the fixed pressing roller 51 so as to cut only one side so as to form a slit on one side. The gap between them is adjusted. Further, when the thickness detecting unit 13 determines that the envelope is inappropriate, the rotary blade 50 is made to escape upward so as not to cut the double envelope 2b. In order to prevent the double envelope 2b from being cut, the direction in which the rotary blade 50 escapes is not limited to the upward direction, and the rotary blade 50 may escape laterally so as to go out of the transport path 18.

The rotary blade 50 cuts only one surface of the outer envelope, and the cutting position is preferably along a side edge of the envelope and at a position of 1 to 2 mm from the edge. This position, by hitting one side edge of the outer envelope to move the inner envelope to one side of the outer envelope, and then setting the double envelope in the device of the present invention, to the inner envelope and the voting paper in it This is a position where only one surface of the outer envelope can be reliably cut without cutting the outer envelope.

In the path along which the envelope is conveyed, one of the side walls along both side edges of the envelope is movable in the width direction so that the envelope can be adjusted in accordance with the width of the envelope, and the other side wall is fixed. In order to set the cutting position of the envelope to the above-described position, the position of the rotary blade 50 is set at a position of 1 to 2 mm from the fixed side wall of the transport path 18 and is fixed in the width direction of the transport path 18. I have.

Each of the transport roller pairs 12, 14, 16 has its lower roller rotated and partially protruded upward from the bottom surface of the transport path 18. Free rotation. The double envelope is passed between them and sent in the transport direction. The upper roller is supported so as to be movable upward about the thickness of the envelope.

A switch 80 for detecting the passage of an envelope is provided in front of the transport roller pair 16. Switch 8
0 has an arm lever protruding above the transport path 18. When the envelope is pushed downward by a transported envelope, the switch 80 is turned on. When the envelope passes and the arm lever protrudes upward, the switch 80 is turned on. Turns off. That is, when the switch 80 is turned off from on, the number of passing envelopes can be counted one by one.

If the thickness detecting unit 13 detects an abnormality (in the case of an improper envelope or a double feed in which two or more envelopes are fed at the same time), the envelope is inserted into the slit unit 15.
When the switch 80 is turned on, the operation of the apparatus is stopped with the switch 80 turned on. At this position, removal of the envelope is easy, and once the switch 80 is turned on, the envelope is removed in a stopped state, so that the switch 80 does not switch from on to off in the operating state. That is, the number of inappropriate envelopes is not counted. When reset to the operation state, the operation is restarted from the state where the switch 80 is off. With this configuration, by applying all double envelopes for which absentee voting has been performed to this device, appropriate and unsuitable envelopes can be separated without opening them. Can be counted automatically.

The means for counting the appropriate number of envelopes is not limited to the above-mentioned switch 80, but may be, for example, from the vertical movement of the movable upper roller 40 of the thickness detecting section 13 or from the swinging operation of the lever member 44. It is also possible to obtain and count the electric signals. In this case, according to the determination result (output signal from the displacement sensor 46) between the appropriate envelope and the inappropriate envelope, only the number of the appropriate envelopes is counted and the signal is electrically transmitted so as to exclude the number of the inappropriate envelopes. To process.
