The medium detecting sensor 40 is a sensor including a light emitting unit 41 emitting light necessary for detecting movement of a medium, and a light receiving unit 42 detecting the light in one body. The medium detecting sensor 40 may detect whether the medium M is transferred through light emission and light reception. The media sensor 40 may also be referred to as a media transport sensor. The media sensor 40 is connected to the control unit of the financial device through a cable 43.

1 is a partial schematic view of a financial device equipped with a media sensor according to the first embodiment, Figure 2 is a graph showing a change in output value according to the distance between the media sensor and the medium.

1 and 2, the financial device according to the present invention includes a transport device and a media sensor 40.

The conveying apparatus includes a guide 20 for guiding the conveyance of the medium, and an upper roller 23 and a lower roller 24 for conveying the medium. The guide 20 includes an upper guide 21 and a lower guide 22. The transport path 10 of the medium is formed between the upper guide 21 and the lower guide 22.

The media sensor 40 is installed in the lower guide 22. Of course, the media sensor 40 may be installed in the upper guide 21.

Hereinafter, the media detection sensor 40 will be described as an example in which the lower guide 22 is installed.

The medium detecting sensor 40 includes a light emitting unit 41 for irradiating light and a light receiving unit 42 for detecting light. The medium detecting sensor 40 including the light emitting unit 41 and the light receiving unit 42 may be referred to as a sensing unit.

In this case, in order to increase the sensitivity of the medium detection sensor 40, the medium detection sensor 40 may be installed at a position where the output P of the medium detection sensor 40 (the output of the light receiving unit) reaches the maximum value P.

When the medium M does not pass through the conveyance path 10 and the medium detecting sensor 40, when the light emitting part 41 emits light, the light is reflected by the upper guide 21 and the The light is received by the light receiving portion 42.

On the other hand, when the medium M passes through the transport path 10 in the T direction and passes through the medium detection sensor 40, the light emitted from the medium detection sensor 40 is emitted from the medium M. It is reflected and received by the medium detection sensor 40.

In this case, the light emitted from the medium detecting sensor 40 is greater than the intensity of light reflected from the other surface of the transport path 10 and received by the medium M. It is possible to detect whether the medium M is transported by changing the intensity of light as described above.

Referring to FIG. 2, the medium detection sensor 40 outputs from the light receiving unit 42 according to the distance between the medium detection sensor 40 and the medium M. FIG.

Referring to FIG. 2, the medium detection sensor 40 outputs the highest value in the P section in which the distance between the medium detection sensor 40 and the medium is about 4 to 6 mm. In addition, about 50% of the maximum value is output in the A section where the distance between the medium sensor 40 and the medium is about 12-14 mm.

As described above, since the output value is different according to the distance between the medium sensor 40 and the medium, it is possible to detect whether the medium is transported according to the output value change when the medium passes through the medium sensor 40. .

According to the present embodiment, since the number of cables inserted into the financial device can be reduced, the failure rate of the device due to cable abnormality can be reduced.

3 is a partial schematic diagram of a financial device equipped with a media sensor according to the second embodiment.

This embodiment is the same as the first embodiment in other parts, except that there is a difference in the shape of the conveyance guide and the output value of the light receiving portion. Hereinafter, the characteristic parts of this embodiment will be described.

Referring to FIG. 3, the media sensor 40 is installed in the lower guide 52, and a hole 53 is formed in the upper guide 51.

When the medium M does not pass through the conveyance path 10 and the medium detecting sensor 40, the light emitted by the light emitting part 41 passes through the hole 53, and thus, the light receiving part 42. It is not received.

When the medium M passes through the transport path 10 and passes through the medium detection sensor 40, the light emitted from the light emitting part 41 is reflected by the medium M to reflect the light receiving part 42. ) Is received.

Therefore, since light is reflected and received only when the medium M passes through the medium detecting sensor 40, it is possible to detect whether the medium M is transferred.

4 is a partial schematic view of a financial device equipped with a media sensor according to the third embodiment, Figure 5 is a graph showing the relationship between the time and the output when passing through the media according to the third embodiment.

This embodiment is the same as the first embodiment in other parts, except that there is a difference in the shape of the conveyance guide and the output value of the light receiving portion. Hereinafter, the characteristic parts of this embodiment will be described.

Referring to FIG. 4, the medium detection sensor 40 is installed in the upper guide 61, and the groove 63 is formed in the lower guide 62. That is, the groove 63 is located on the opposite side of the medium detection sensor 40 (light emitting unit and light receiving unit) based on the transfer path of the medium.
The reflector 70 may be coupled to the groove 63. Here, the reflective plate 70 may be coupled to the bottom surface or the ceiling surface of the groove 63, but the groove 63 may not be formed and only the reflective plate 70 may be attached to the upper guide 610. have.

The groove 63 or the reflector plate 70 maintains a reference range when the medium M is in a non-feeding state. For example, referring to FIG. 1, the position of the groove 63 or the reflector 70 may be adjusted such that the output of the light receiver 42 is 40 to 60% (A) of the maximum value P. The reference range of the light receiving unit 42 output may be appropriately selected in consideration of the error range of the output.

In addition, when the medium M is in the transported state, the output of the light receiving portion 42 rises above the reference range. In this case, the output of the light receiving unit 42 may be adjusted to be a maximum value P or a value close to the maximum value P.

If the output of the light receiving unit 42 is measured to be lower than the reference range, it is determined that the media sensor 40 has a failure. If it is determined that a failure has occurred in the medium detection sensor 40, the failure display unit may notify that a failure has occurred. As a result, it is possible to check whether the medium detection sensor 40 operates normally in the state in which the medium M is not transferred.

As an example, referring to FIG. 5, when power is applied to the medium detection sensor 40, the medium detection sensor 40 is in a standby state in which the medium M does not pass through the medium detection sensor 40. Maintain ~ 60% output. In t1 to t2 of FIG. 5, the medium M passes through the medium detection sensor 40. At this time, 90 to 100% of the maximum value of the output of the medium detection sensor 40 is output. After the medium M passes through the medium detection sensor 40 (t2 to t3 in FIG. 5), the output of the medium detection sensor 40 again maintains an output value close to 50% of the maximum value P. FIG. .

Similarly, t3 to t4, t5 to t6,... Also, as in the t1 to t2, the output of the medium detecting sensor 40 is output 100%. In addition, once the medium M passes (t4 to t5, t6 to t7, ... of FIG. 5), the output of the medium detecting sensor 40 maintains an output value close to 50% as described above.

Hereinafter, an operation method of the medium sensor 40 will be described.

When power is applied to the medium detection sensor 40, the medium detection sensor 40 generates an output of a reference range in a normal state. When the output of the medium detection sensor 40 reaches a steady state, it is determined whether the output of the medium detection sensor 40 falls within a reference range. If the output of the medium sensor 40 is determined to be less than the reference range, it is determined that the medium sensor 40 has a failure. If it is determined that the output of the medium detection sensor 40 exceeds the reference range, the medium M is considered to have been transferred. If the output of the medium detection sensor 40 does not rise, the medium detection sensor 40 continuously determines whether the output falls within a reference range while maintaining a normal state.

The above description may be applied to all devices equipped with a sensing sensor 40 capable of sensing an object as well as a financial device. In this case, the groove 63 including the sensor 40, the reflector 70, etc. may be referred to as a sensing device. However, since the transport path 10 described above has a concept of a space in which an object can be located, the transport path 10 may be described as a space for positioning an object.
