Abstract

A paper medium receiving device and automatic teller machine. The receiving device comprises a roller (20). When the roller (20) is in a rotating state, monitoring ridges (41) distributed along a circumferential direction of a rotation shaft (10) pass a monitoring sensor (50) sequentially. Each pair of adjacent ribs (221) and the rotating shaft (10) enclose to form one sector-shaped region (23), and projections of the monitoring ridges (41) along an axial direction of the rotating shaft (10) have a one-to-one correspondence with and are located within projections of the sector-shaped regions (23). As a result, when the monitoring sensor (50) detects the passing of any one of the monitoring ridges (41), a first detection signal (30a) generated by a remaining paper sensor (30) is not blocked by the ribs (221), and at the same time, the remaining paper sensor (30) is activated to determine whether a paper medium remains on the roller (20), thus preventing the situation in the prior art in which a rib (221) blocking a paper medium receiving device causes incorrect determination of whether a paper medium remains, and improving the reliability of remaining paper medium detection.

The transparent material cannot add an antistatic additive, which affects the first detection signal 30a. This solution cannot transfer static electricity on the paper medium to the rack and then to the ground through the grounding device on the rack, so the static electricity of the paper medium in contact with the drum 20 cannot be eliminated. The drum 20 can be made of a material that can conduct static electricity. Preferably, rolling The cartridge 20 can be made of a transparent conductive material that allows the residual sensor 30 to operate normally without the monitoring sensor 50 being engaged, as well as to eliminate static electricity from the paper medium.

Understandably, as long as The projections of the axial monitoring ribs 41 along the axis of rotation 10 are in one-to-one correspondence within the projection of the sector-shaped region 23, so that any one of the monitoring ribs 41 passes through the monitoring sensor 50, allowing the first detection signal 30a to pass through the annular region 26 without Blocked by the ribs 221.

[0054] Further, referring to FIG. 1 and FIG. 2, in two symmetrically disposed drums 20, a gear 70 of the rotating shaft 10 adjacent to one of the drums 20 is provided with a gear 70 rotating in synchronization with the rotating shaft 10 for powering Transfer to the banknote pulley (not shown).

[0055] Further, please refer to FIG. 4, which further includes a wheel body 40 disposed on the rotating shaft 10 and rotating in synchronization with the rotating shaft 10, and the monitoring rib 41 is disposed on the wheel body 40 along the circumferential direction of the wheel body 40. This structure is compact. Specifically, the wheel body 40 is a synchronous wheel 40, and the synchronous wheel 40 receives the power of the rotary driving member through the toothed timing belt 80 to rotate the rotating shaft 10. Further, the rotating shaft 10 has a profiled section 11, and the middle portion of the wheel body 40 is provided with a type of face 42 which can be passed through the type of face 42 to limit the wheel body 40 to the rotating shaft 10 along the circumferential direction of the rotating shaft 10. on. This structure facilitates fixing the monitoring rib 41 and the rib 221 at predetermined positions. In the present embodiment, the sections of the profiled section 11 and the profiled face 42 are both D-shaped.

The adjusting wheel 90, the one side of the adjusting wheel 90 facing the wheel body 40 extends to form a plurality of extending arms 91 corresponding to the recesses, and the wheel body 40 extends into the groove one by one. The middle cymbal is limited to the adjustment wheel 90 along the circumferential direction of the adjustment wheel 90. After the paper medium residual 吋 is detected on the drum 20, the adjusting arm 90 is axially pushed along the rotating shaft 10, so that the extending arms 91 of the adjusting wheel 90 project into the grooves of the wheel body 40 one by one, and the adjusting wheel 90 is manually rotated. , the upper and lower bills are ejected from the drum 20 and the paper medium is ejected between the upper and lower bills.

[0057] In the present embodiment, the number of the ribs 221 is six, and the ribs 221 are evenly distributed along the circumferential direction of the rotating shaft 10. The number of monitoring ribs 41 is six, and the monitoring ribs 41 are evenly distributed along the circumference of the rotating shaft 10. The rib 221 and the monitoring rib 41 correspond to a certain positional relationship. Referring to FIG. 5 to FIG. 8, the drum 20 is sequentially rotated in the reverse direction. When the monitoring edge 41 passes through the inter-turn portion of the monitoring sensor 50, the first detection signal 30a generated by the first signal generator 31 is adjacent. The gap between the two ribs 221 enters the annular region 26, passes through the gap between the adjacent two ribs 221, and is received by the first signal receiver 32. It can be understood that, in Figs. 5 to 8, the overall structure remains unchanged, and the drum 20 is sequentially rotated in the direction of the needle, and this solution can also realize the detection of the residual of the paper medium on the drum 20. [0058] When the drum 20 is made of a material that the first detection signal 30a cannot penetrate, the paper medium residual can be detected by monitoring the cooperation of the sensor 50 with the residual sensor 30. Referring to FIG. 9, the second detection signal 50a of the monitoring sensor 50 is six rectangular waves during one rotation period. When the monitoring edge 41 enters the monitoring sensor 50, the second detection signal 50a is at a high level. , is low. The residual sensor 30 starts the detection when the second detection signal 50a is at a high level, and when the medium is blocked, the first detection signal 30a is at a high level, and vice versa. Since the rib 221 on the drum 20 is at a low level in the second detection signal 50a, if the residual sensor 30 is turned on, the second detection signal 50a of the residual sensor 30 is blocked by the rib 221, so according to this scheme, it is possible to avoid The influence of the ribs 221 on the residual sensor 30 improves the reliability of the residual detection.

[0059] When the drum 20 is made of a material that the first detection signal 30a can penetrate, the residual paper medium on the drum 20 can be detected by the residual sensor 30 alone.

10°, a maximum of two ribs 221 are distributed in the range of the detection angle of the residual sensor 30; the number N of the ribs 221 on the drum 20 is 6; the angle A2 of the ribs 221 on the drum 20 is 8°.

A3=360 N=360 6=60°

[0063] The angle at which the residual sensor 30 is located is from the angle of the nearest rib 221, that is, the maximum angle for occluding the monitoring rib 41 is:

[0064] Α4=Α1-Α3-2*Α2=110 ^ο -60°-2*8°=34 ^ο

[0065] Considering the thickness, manufacturing error, and assembly error of the rib 221, in order to ensure its reliability, it is necessary to set a safety factor Κ, and the Κ value is greater than 1.

[0066] In the present embodiment, taking Κ=2, the design angle for occluding the monitoring edge 41 is:

Α5=Α4/Κ=34 2=17°

[0068] Referring to FIG. 10, a paper medium storage device according to a second embodiment of the present invention is substantially the same as the paper medium storage device provided in the first embodiment, and the second detection signal of the monitoring sensor 50 is still monitored. The residual condition is detected by the residual sensor 30 on the premise of the occlusion of the 41, which is different from the first embodiment in that the number of the ribs 221 and the monitoring ribs 41 is changed.

[0069] Specifically, it is known that the detection angle range A1 of the residual sensor 30 on the drum 20 is 110°, in the residual sensing A maximum of two ribs 221 are distributed in the range of the detection angle of the damper 30; the number N of ribs 221 on the drum 20 is 4; and the angle A2 of the ribs 221 on the drum 20 is 8°.

[0070] Then, the angle between each two ribs 221 on the drum 20 is:

[0071] A3=360 N=360 4=90°

[0072] The angle at which the residual sensor 30 is located is the distance from the nearest rib 221, that is, the maximum angle for occluding the monitoring rib 41 is:

0074=2*Α3-Α1-2*Α2=2*90 ^ο -110°-2*8°=54 ^ο

[0074] Considering the thickness, manufacturing error, and assembly error of the rib 221, in order to ensure its reliability, it is necessary to set a safety factor Κ, and the Κ value is greater than 1.

[0075] In this embodiment, taking Κ=2, the design angle for occluding the monitoring edge 41 is:

[0077] Referring to FIG. 11, a paper medium storage device according to a third embodiment of the present invention is substantially the same as the paper medium storage device provided in the first embodiment, and the second detection signal of the monitoring sensor 50 is still monitored. The residual condition is detected by the residual sensor 30 on the premise of the occlusion of the 41, which is different from the first embodiment in that the detection angle range A1 of the residual sensor 30 on the drum 20 is changed to 30°, and the detection angle of the residual sensor 30 is the most One rib 221 is distributed; the number Φ of the ribs 221 on the drum 20 is 6; the angle Α2 of the ribs 221 on the drum 20 is 8°. This solution also enables paper medium residue detection on the drum 20.

[0078] It can be understood that the number of the ribs 221 and the monitoring ribs 41 is not limited, and the number of the ribs 221 and the ribs 221 are equal to each other, and the ribs 221 and the monitoring ribs 41 are correspondingly disposed in a certain positional relationship. Specifically, the monitoring ribs 41 are disposed in the sector-shaped area one by one, and the ribs 221 - 1 are correspondingly located in the sector-shaped area. Under the premise that the second detection signal of the monitoring sensor 50 is blocked by the monitoring edge 41, the roller can be detected by the residual sensor 30. Residual paper media on 20.

[0079] Referring to FIG. 12, a paper medium storage device according to a fourth embodiment of the present invention is substantially the same as the paper medium storage device provided in the first embodiment, and is different from the first embodiment in that: the monitoring edge 41a is disposed. At a position where the monitoring edge is not originally provided, the processor detects that the second detection signal is not blocked by the monitoring edge 41a, and activates the residual sensor 30 to cause the residual sensor 30 to detect the blocking condition of the first detection signal 30a and The occlusion condition of the first detection signal 30a determines whether the drum 20 has a paper medium remaining. This solution also enables paper medium residue detection on the drum 20. [0080] The automatic teller machine provided by the embodiment of the invention includes a paper medium storage device. The drum is placed in a rotating state, and the monitoring edges distributed along the circumference of the rotating shaft pass through the monitoring sensor in sequence. Since the two adjacent ribs and the rotating shaft are enclosed, a sector-shaped area is formed, and the projection of the ribs along the axial direction of the rotating shaft is correspondingly located in the projection of the sector-shaped area, and any monitoring edge is detected by the monitoring sensor. The first detection signal generated by the residual sensor is not blocked by the ribs, and then the residual sensor is activated to determine whether there is any paper medium remaining on the drum, so as to avoid misidentification of the paper on the drum if the existing paper medium storage device is blocked by the ribs. The residual medium is used to improve the reliability of paper medium residue detection.

The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalents, and improvements made within the spirit and scope of the present invention should be included in the present invention. Within the scope of protection.
