In addition, the automatic teller machine is provided with a paper medium separation module for separating and supplying a paper medium such as cash or check.

The feed roller and the gate roller constituting the paper medium separation module overlap each other to form an overlapped state, and the separation process of the paper medium is completed while passing the overlap.

In this process, if the overlap state is too small, it is impossible to pass the paper medium itself. If the overlap state is too large, there is a problem that the paper medium is not separated. Thus, the size of the overlap greatly affects the performance of the separation module.

On the other hand, in order to mass-produce such a paper medium separation module, a performance measuring device is used. The conventional performance measuring device is not equipped with a system capable of accurately verifying the performance of the separation module in the process of producing the separation module.

That is, the performance measuring apparatus of the conventional media feeder has no means for measuring whether the paper medium passing through the separation module is transferred in an oblique state (meander or skew) or the gap between the paper medium is smaller than a predetermined reference value. .

In addition, even when the sensor is installed in the performance measuring device, the optical sensors installed at two locations in the transverse direction perpendicular to the advancing direction of the paper medium could only grasp the skew amount of the paper medium. There is also a problem that can not determine the amount of bias.

In addition, there is a problem that there is not provided a separate device for checking the separation module by mounting the paper medium separation module mounted on the finished product in use.

The present invention provides a performance measuring apparatus of a media supply apparatus capable of checking an operation state of a separation module by separating and mounting a paper medium separation module used in a financial automated machine.

Here, the first and second sensing modules preferably include a light emitting part installed above the paper medium transport path and a light receiving part installed below the paper medium transport path corresponding to the light emitting part in a vertical direction.

By the above configuration, it is possible to accurately measure whether the paper medium is separated from the separation module, and whether the paper medium is skewed or whether the paper medium is shifted in the transfer path, that is, from the center line of the transfer path or the paper medium. You can also detect gaps between them.

The light emitting unit may include a plurality of light emitting elements arranged to correspond to the length of the sensing section, and the light receiving unit may include a plurality of light receiving elements arranged to correspond to the length of the sensing section.

And a sensing module 131 and 132 and a second sensing module 133 and 134. The first sensing module 131 and 132 and the second sensing module 133 and 134 may include a skew of a paper medium or a gap between the paper medium or a paper path. It is determined whether the deviation is from, that is, the amount of shift or shift (shift). The detailed configuration of the paper medium conveying unit 140 will be described later.

On the other hand, the driving unit 160 is mounted on one side of the central portion of the performance measuring device 100 of the medium supply device. The driving unit 160 may pass through the guide unit 150 through a separation medium 161 driving the pickup roller (not shown) of the paper medium separation module 120 and the paper medium passing through the paper medium separation module 120. And a feed motor 162 to make it possible.

Here, the separation motor 161 and the transfer motor 162 is preferably a stepping motor. This is because the stepping motor can be easily driven and stopped because the stepping motor can be rotated at a predetermined angle by the digital signal.

On the other hand, the frame 110 is a member formed in a substantially thin plate shape, and forms both sides in the longitudinal direction of the performance measuring device 100 of the media supply device. The frame 110 is composed of a first frame 111 and a second frame 112 mounted to face it.

Referring to FIG. 3, the frames 111 and 112 have a separation module accommodating part 112a for accommodating and fixing the paper medium separating module 120, and a transport motor mounting part for mounting the transport motor 162 (not shown). H) may be formed.

Here, the separation module accommodating part 112a is preferably formed in the second frame 112 adjacent to the separation motor 161, and in some cases, the accommodating part may be formed in the first frame 111.

The separation module accommodating part is not formed in the first frame 111, and the separating module accommodating part 112a is formed only in the second frame 112. At this time, the separation module accommodating part 112a is advantageously formed in a slot shape having the same width as that of the separation motor 161 constituting the separation module 120. (See dotted line in FIG. 3).

The separation module accommodating part 112a and the transport motor mounting part are formed through the frames 111 and 112, and the separation motor 161 and the transport motor 162 are fixed to the frames 111 and 112 around the accommodating part 112a. Fastening means mounting holes for mounting the fastening means and the like may be formed.

On the other hand, the photographing device mounting portion (not shown) may be formed in an adjacent portion of the separation module accommodating portion 112a on which the paper medium separation module 120 is mounted. The photographing device mounting unit is for mounting a photographing device such as a camera for observing the overlap of the paper medium separation module 120. As such, by directly attaching the photographing apparatus to the performance measuring apparatus 100 of the media feeder, the overlap state of the paper medium separation module 120 can be observed in real time so that the overlap state can be known in real time. It has the advantage of being managed correctly.

In this case, the photographing apparatus may be effectively mounted on the frames 111 and 112, but is not limited thereto. The photographing apparatus may be directly mounted on the paper medium separation module 120.

On the other hand, as shown in Figure 2, the paper carrier portion 140 is configured to include a guide portion 150 and the sensor 130 formed on both sides of the guide portion 150 to serve as a transfer path of the paper medium do.

On the other hand, the sub-frame 142 for mounting the guide portion 150 and the first and second sensing modules (131, 132, 133, 134) is formed on both sides of the paper carrier portion 140. The subframe 142 is preferably formed of a plate-like member, and various holes for mounting the guide unit 150 and the sensor 130 are formed.

In addition, the sub frame 142 may be mounted on the frames 111 and 112 of the performance measuring device 100 of the media supply device. In this case, the first and second sensing modules 131, 132, 133, and 134 are directly mounted on the frames 111 and 112. May be

The first and second detection modules 131, 132, 133, and 134 may be formed at positions where the edges of the paper medium separated from the paper medium separation module 120 can be detected. That is, the first and second detection modules 131, 132, 133, and 134 may be installed at both sides of the center line of the short side of the paper medium so as to transmit or receive a sensing signal, and may be formed to sense both ends of the paper medium in the longitudinal direction. Here, the short side direction of the paper medium may be regarded as a direction perpendicular to the longitudinal direction of the paper medium.

On the other hand, the sensing module (131, 132, 133, 134) is installed on one side from the center line in the short side direction of the paper medium is transported along the first sensing module (131, 132) and the conveying path to form a sensing section of a predetermined length toward one short side of the paper medium. And second sensing modules 133 and 134 installed on the other side from the center line of the short side of the paper medium to form a sensing section having a predetermined length toward the other short side of the paper medium.

As such, by determining the mounting positions of the first and second sensing modules 131, 132, 133, and 134, the paper media separation module 120 may determine whether the paper media are correctly separated, and the paper media may be slanted. It is also possible to detect whether it is in skew or the gap between the paper media or how far the paper media is transferred away from the centerline of the transfer path, that is, the amount of bias.

If the paper medium advances obliquely due to an abnormal operation of the paper medium separation module 120 or the distance or distance between the paper mediums is smaller than a predetermined reference value or the paper medium is shifted from the center line of the transfer path, Since the media may be wrinkled or jam may occur, maintaining the proper spacing between the paper media or skew may be an important performance determinant of the paper media separation module 120.

Herein, the first sensing modules 131 and 132 and the second sensing modules 133 and 134 may be optical sensors and edge sensors. This is because the edge sensor has a plurality of light emitting parts and light receiving parts, so that relatively accurate sensing is possible. In particular, it is possible to accurately measure how much the paper medium deviates from the center line of the conveying path, that is, the amount of bias. However, the edge sensor is not limited to the optical sensor but may be applied to an ultrasonic sensor. A more detailed description thereof will be described later.

At this time, the light medium of the first and second sensing modules 131, 132, 133 and 134 is disposed at one of the upper and lower parts of the paper medium, and the light receiving unit of the first and second sensing modules 131, 132, 133 and 134 is disposed at the other of the paper carriers. In addition to accurately detecting the condition, the first and second sensing modules 131, 132, 133, and 134 may be disposed at both ends of the conveying path of the paper medium, thereby measuring skew of the paper medium or abnormal distance between the paper mediums, or the amount of deviation of the paper medium. have.

Here, the separation of the paper medium, skew angle, the amount of skew of the paper medium to the interval between the paper medium can be known by measuring the time required to change the signal transmitted or received by the first and second sensing modules (131, 132, 133, 134).

4A and 4B schematically illustrate first sensing modules 131 and 132 used in the performance measuring apparatus 100 according to the exemplary embodiment of the present invention.

The light emitting unit 131 illustrated in FIG. 4A is a light emitting unit of the first sensing modules 131 and 132 installed on the upper portion of the guide unit 150. The light receiving unit 132 illustrated in FIG. 4B is a path for transporting a paper medium. The light receiving units of the first sensing modules 131 and 132 installed under the guide unit 150 to be positioned on the same vertical line as the light emitting unit 131. However, the arrangement of the first sensing modules 131 and 132 is just one example, and the light emitting unit 131 illustrated in FIG. 4A is installed below the guide unit 150, and the light receiving unit 132 illustrated in FIG. 4B is provided.

That is, the light emitting part 131 and the light receiving part 132 include body parts 131a and 132a and power supply parts 131b and 132b. At least one sensor side mounting hole 131c, 132c is formed at the edge of the body portions 131a, 132a.

Meanwhile, referring to FIG. 5, the light emitting part 131 mounted on the upper portion of the paper medium N and the light receiving portion 132 mounted on the lower portion face each other based on the paper path N or the transfer path of the paper medium. It is mounted to configure the first detection module (131, 132). In addition, the second sensing modules 133 and 134 are formed at positions symmetrical with the first sensing modules 131 and 132 with respect to the short side direction center line of the paper medium N. Here, the sensing module 133 formed on the upper portion of the paper carrier transfer path is a light emitting unit, and the sensing module 134 formed on the lower side is a light receiving unit.

At this time, a plurality of light emitting elements 131d and 133d and light receiving elements 132d and 134d are closely formed at the front end surfaces of the light emitting units 131 and 133 and the light receiving units 132 and 134 which constitute the first and second sensing modules 131, 132, 133 and 134. The plurality of light emitting devices 131d and 133d and the light receiving devices 132d and 134d may transmit or receive a sensing signal to cross the transfer path of the paper medium N.

Since the paper medium N shown in FIG. 5 shows the shape seen from the thickness direction of the paper medium, the transfer path of the paper medium N is transmitted from the light emitting elements 131d and 133d and the light receiving elements 132d and 134d. Alternatively, it can be seen that the signal intersects with the sensing signal (see arrow of FIG. 5).

Meanwhile, the first and second sensing modules 131, 132, 133, and 134 are mounted such that an edge of the paper medium N may pass between the light emitting elements 131d and 133d and the light receiving elements 132d and 134d, and the paper medium N It can be mounted in at least two places along the longitudinal direction of).

The total length detected by the light emitting units 131 and 133 and the light receiving units 132 and 134 of the two sensing modules 131, 132, 133, and 134 is about 60 mm.

In this case, the length of the paper medium sensed by the pair of sensing modules may be referred to as a sensing section, and the sensing section may be about 30 mm long for each sensing module. That is, in FIG. 5, the sensing interval by the first sensing modules 131 and 132 is a length covered by the light emitting element 131d and the light receiving element 132d, and the sensing interval by the second sensing module 133 and 134 is the light emitting element. 133d and the light receiving element 134d. Therefore, a plurality of light emitting elements 131d and 133d and light receiving elements 132d and 134d are arranged in correspondence with the length of the detection section.

As such, the first and second sensing modules 131, 132, 133, and 134 made up of the light emitting parts 131d and 133d and the light receiving parts 132d and 134d face each other, whereby an optical signal emitted from the light emitting parts 131 and 133 is received. It can be recognized whether or is blocked by the paper medium (N).

As described above, the first and second detection modules 131, 132, 133, and 134 include a plurality of light emitting elements and light receiving elements so that the edges of the paper medium N can be recognized, thereby functioning as an edge sensor, thereby increasing the accuracy of sensing.
