The uppermost surface of the bundle of sheets (2) set between (25) and (25) is provided on the supply plate (27) at an inclination angle so as to contact the feed roller (18). Then, this inclination angle is the most suitable angle for feeding the sheet (2) into the feed roller (18).

Further, the holding plate (26) can slide the guide groove by its own weight according to this inclination, and presses and biases the sheet (2) toward the feed roller (18). And the holding plate (26)
When not in use, the locking piece (28) provided at the end is magnetically attached to the magnetizing plate (30) provided at the outer end of the supply plate (27).

An elastic material separating plate (31) is brought into contact with the lower surface of the feed roller (18), and the separating plate (31) is fixed to the Z-shaped crank (34) via the separating table (32). ing. And
The other end of the Z-shaped crank (34) is rotatably supported by the driven shaft (35) and the Z-shaped crank (34) is urged by the tension spring (36) toward the separating plate (31). . The sheet (2) to be fed can be elastically held by constantly elastically urging the separating plate (31) toward the feed roller (18).

Further, the drive shaft (19) of the feed roller (18) is provided with a rotating cam (38) forming the second intermittent drive mechanism (37), a large diameter portion (40) and a small diameter portion (41). It is provided and fixed. When the drive shaft (19) rotates, the intermittent lever (42) is intermittently rotated and pressed by the large diameter portion (40) of the rotary cam (38) so as to face the rotary cam (38). ) Is provided.

During this time, the lever (42) has a rotating roller (4
It is pressed by the rotating cam (38) via the shaft 3) and is pressed and biased by the rotating cam (38) by the spring (47). The end of the intermittent lever (42) is pivotally fixed to a one-way clutch (44) that rotates only in one direction. The one-way clutch (44) is connected to the carrying shaft (45) so that the carrying shaft (45) can be rotated only in one direction.

The driven pulley (46) is fixed to the transport shaft (45), and the driven pulley (50) is rotatable on the driven shaft (35) arranged in parallel with the transport shaft (45) at a constant interval. Fixed to. The feed belt (51) of the seat (2) is suspended between the drive pulley (46) and the driven pulley (50).

In addition, the feed belt (51) includes a drive pulley (46),
Together with the driven pulley (50), a pair is formed in parallel at an appropriate interval. Further, the feed belt (51) is exposed slightly above the surface of the supply plate (27) through an exposure opening provided in the supply plate (27) and is inclined to the surface of the supply plate (27). The lower edge of the sheet (2) to be placed is in contact with the feed belt (51).

Further, the feed belt (51) includes a manual operation member (5) fixed to the transfer shaft (45) via a one-way clutch (44).
By 2), it is possible to move in the direction of the feed roller (18).

In order to feed the sheet (2) into the conveying means (1) in the above-described structure, first, the bundle-shaped sheet (2)
As shown in FIG. 1, the sheet is placed vertically on the upper surface of the supply plate (27), and the sheet surface is supported by the guide rollers (24) (25). Then, the distance between the sheet guides (22) and (23) is matched with the width of the sheet (2). When the holding plate (26) magnetically attached to the magnetizing plate (30) is released, the holding plate (26) slides on the upper surface of the supply plate (27) and the sheet (2) The bundle is urged toward the feed roller (18).

Next, if the manual operation member (52) is rotated, this rotation is
The transport shaft (45) is rotated through the one-way clutch (44), and the feed belt (51) is moved through the drive pulley (46).
Rotate in the sheet feeding direction. And feed belt (51)
Is arranged slightly above the supply plate (27), so that the lower end edge of the sheet (2) comes into contact with the supply plate (27) and moves, and the pressing plate (26) with the contact points of the guide rollers (24) and (25) as fulcrums. Fall in the direction. Therefore, the sheet (2) is arranged in parallel with the holding plate (26) and the sheet (2) on the conveying means (1) side is pressed and brought into contact with the feed roller (18). It is possible to know that the torque has increased and the setting of the seat (2) has been completed.

In this state, the bundle of sheets (2) has an oblique shape parallel to the holding plate (26), but the bundle of sheets (2) is obliquely formed on the supply plate (27) without using the above means. In order to set, it is necessary to manually handle the bundle of sheets (2) into an oblique shape before setting, which requires a high level of skill. But,
By using the above method, accurate setting can be made possible without any skill required.

Next, the prime mover (16) is rotated, and this rotation is transmitted to the drive shaft (19) through the rotary shaft coupling mechanism (20), whereby the feed roller (18) is rotated. Along with this rotation, the sheet (2) that is in contact with the sheet supply unit (17) is sandwiched between the separating plate (31) and separated, and conveyed through the delivery rollers (53) (54). The sheet is fed into the sheet supply port (6) of the means (1).

This feeding is performed by the supply detecting means (12) of the conveying means (1).
Is detected, the rotary shaft coupling mechanism (20) is controlled to stop the transmission of the rotational force to the feed roller (18), and to stop the continuous supply of the sheet (2) to the conveying means (1). By the above operation, the drive shaft (19) and the feed roller (18) rotate about 180 degrees in one embodiment.

Also, as the feed roller (18) rotates from start to stop, the drive shaft (1
The rotating cam (38) of 9) also rotates. This rotating cam (3
Due to the large diameter portion (40) of 8), the intermittent lever (42) is pressed counterclockwise while resisting the restoring force of the spring (47) via the rotating roller (43), and the rotating cam (38) is also provided. When the small diameter portion (41) of () contacts the intermittent lever (42), the pressure on the intermittent lever (42) is released, and the restoring force of the spring (47) restores the intermittent lever (42) to its original position. .

By the reciprocating rotation of the intermittent lever (42), the transport shaft (45) connected to the intermittent lever (42) via the one-way clutch (44) is intermittently rotated only in one counterclockwise direction. Then, the drive pulley (46) fixed to the transport shaft (45) is intermittently rotated to suspend the feed belt (51) of the seat (2) suspended between the drive pulley (46) and the driven pulley (50). ) Rotate. By this rotation, the lower end comes into contact with the feed belt (51), and the sheet (2) arranged in the sheet supply section (17) is transported in the direction of the feed roller (18).

The transfer of the sheet (2) in the direction of the feed roller (18) corresponds to the feeding of one sheet (2) into the conveyance means (1), and the movement amount is set so that only one sheet (2) is operated. I am adjusting.

Further, even when the operation of the feed roller (18) is stopped by the operation of the supply detecting means (12), the conveying means (1) continues to operate, and the barcode information is read by the barcode reading mechanism (8). The sheet (2) having been read is conveyed to the sheet discharge port (7) and detected by the discharge detection means (15). By detecting the sheet (2) of the discharge detecting means (15), the rotary shaft coupling mechanism (20) is controlled, and the rotational force of the prime mover (16) is transmitted to the feed roller (18) of the sheet supply unit (17). By this, the next sheet (2) can be fed into the conveying means (1).

Therefore, the feeding roller (18) for feeding the sheet (2) to the conveying means (1) ejects the sheet (2) from the conveying means (1) after the sheet (2) is fed to the conveying means (1). Until it is discharged and the discharge is completed,
The feeding of the next sheet (2) is repeated. Therefore, while using a normal prime mover (16),
It is possible to obtain the same technical effect as when an expensive stepping motor is used.

Effect of the Invention Since the present invention is configured as described above, the form,
In a sheet feeding device for feeding a sheet to a sheet conveying device for reading information such as bar code, magnetic information, and code displayed on a relatively small sheet such as a prepaid card, a magnetic card, a punch card, and an aperture card. In addition, it is possible to set the sheet bundle in an oblique shape without setting any skill.
