The banknote transport mechanism 110 includes transport rollers 111 and 112 that are rotatably supported and opposed by the support mechanism 120 in the width direction (horizontal direction) of the intra-identification transport path 111P that constitutes a part of the transport paths 5 to 14. I have. The transport rollers 111 and 112 receive a rotational driving force from a transport motor (not shown), and transport the bills one by one while sandwiching the bills from above and below. The transport rollers 111 and 112 are formed with an elastic member such as rubber so that the transport rollers 111 and 112 can be smoothly transported even with respect to a damaged banknote such as a broken bill or a broken bill. It has a high configuration. The support mechanism 120 rotatably supports the above-described transport rollers 111 and 112, is equipped with a sensor group 150, and further performs maintenance work such as taking out from the outside when a banknote is jammed in the intra-identification transport path 111P. And a support base material 122, a first support mechanism 130, and a second support mechanism 140.

  FIG. 3 is an exploded perspective view of the paper sheet identification device 40.

And. Transport rollers 111 and 112 are rotatably supported by the first support portion 124.

  The first support mechanism 130 is a mechanism for supporting a part of the sensor group 150, and includes a first support member 132, an arm member 134, and a shaft body 136. The first support member 132 is a member spanned in the transport direction, and is arranged in the direction intersecting the transport direction and is attached to the first support portion 124 by the shaft body 136 that passes through the support hole 124a of the first support portion 124. It is pivotally supported so that it can rotate. The arm member 134 is supported by the first support member 132 via the connection fixing pin 134a, and is urged in the rotation direction so as to return to the illustrated position by a spring (not illustrated). An engagement recess 134 b is formed at the tip of the arm member 134. The engaging recess 134 b regulates the opening of the first support mechanism 130 with respect to the support base material 122 by engaging with a fixing pin 127 a protruding from the side surface of the support base material 122. The first support portion 124 and the shaft body 136 constitute a first shaft support mechanism 137 that supports the first support member 132 so as to be rotatable with respect to the support base material 122. The arm member 134 and the fixing pin 127a constitute a first lock mechanism 138.

  The second support mechanism 140 is a mechanism for supporting a plurality of sensors of the sensor group 150 in substantially the same manner as the first support mechanism 130, but faces the first support mechanism 130 along the intra-identification transport path 111P. And the arrangement of the sensor group 150 are different from those of the first support mechanism 130. That is, the second support mechanism 140 includes a second support member 142, an arm member 144, and a shaft body 146 disposed in parallel with the shaft body 136, and a shaft that passes through the support hole 126 a of the second support portion 126. The body 146 is rotatably supported on the first support portion 124. The arm member 144 is supported by the second support member 142 via the connection fixing pin 144a, and is urged in the rotational direction by a spring (not shown) so as to return to the position shown. The engagement recess 144b at the tip of the arm member 144 is engaged with a fixing pin 127b protruding from the side surface of the support base 122, so that the second support mechanism 140 opens with respect to the support base 122. Is regulated. The arm member 134 and the shaft body 146 constitute a second shaft support mechanism 147 that supports the second support member 142 so as to be rotatable with respect to the support base material 122. Further, the arm member 144 and the fixing pin 127b constitute a second lock mechanism 148. The relationship between the first support mechanism 130 and the second support mechanism 140 will be described later.

  In FIG. 2, the sensor group 150 includes a first sensor 151, a second sensor 152, and a third sensor 153 for reading the feature of the banknote. The first to third sensors 151, 152, and 153 are divided into a support base 122, a first support mechanism 130, and a second support mechanism 140, and a transmitter and a receiver, with the intra-identification transport path 111 </ b> P separated. Are arranged respectively. That is, the sensor group 150 separates the gap Gp of the intra-identification conveyance path 111P from the support base 122, the first support member 132, and the second support member 142 for each of the first to third sensors 151, 152, and 153. Are arranged. For example, in the first to third sensors 151, 152, and 153, the receivers 151 a, 152 a, and 153 a are disposed on the upper surface of the base 123 of the support base 122, while the transmitter 151 b is disposed on the first support mechanism 130. The first support member 132 is disposed, and the transmitters 152b and 153b are disposed on the second support member 142 of the second support mechanism 140, respectively. Note that the receiving unit and the transmitting unit of the sensor described above may be disposed on any of the support base 122, the first support mechanism 130, and the second support mechanism 140, and also serving as the receiving unit or the transmitting unit. It may be a configuration arranged only in the above.

  As an example of the sensor of the sensor group 150, one that uses various information such as image data obtained by scanning a banknote, uneven shape on the surface of the banknote, magnetic characteristics, optical characteristics with respect to ultraviolet rays, and the like can be applied. As a specific configuration of such a sensor, an optical element obtained by irradiating a paper sheet with light using an LED light projecting element and a photodiode light receiving element as a transmitting unit and a receiving unit, and transmitting the paper sheet. A sensor for detecting a magnetic component included in a bill can be used by arranging a sensor for reading an output, an excitation coil for forming a magnetic field, a detection coil for detecting a magnetic field, and a control unit thereof. That is, the sensor is not limited to the above-described configuration, and a device that outputs some detection signal for detecting the characteristics and state of the paper sheets passing through the conveyance path can be applied.

  The paper sheet identification device 40 includes an encoder (not shown) and a control unit 160. The encoder is a device that outputs a clock signal in synchronization with a bill conveyance distance based on a conveyance drive by the bill conveyance mechanism 110. The control unit 160 is a device that processes the detection signal output from the sensor group 150 and outputs a signal that allows the control unit 80 (FIG. 1) to determine the denomination, number, and authenticity. The sensor and the encoder are formed of a member that is strong against bending such as a flexible cable in order to improve connection reliability even with respect to the opening operation of the first support mechanism 130 and the second support mechanism 140. With such a configuration, the paper sheet identification device 40 identifies which denomination is the banknote conveyed in the intra-identification conveyance path 111P, further identifies whether it is a genuine note or a fake note, and further 1 It discriminates whether it is a sheet, two sheets or three or more banknotes, and outputs a signal for managing transactions and used banknotes. In addition, the paper sheet identification apparatus 40 is comprised so that the characteristic may be identified even if the banknote conveyed by the banknote conveyance mechanism 110 is conveyed from which direction.

  FIG. 4 is an explanatory diagram for explaining the opening / closing operation of the paper sheet identification device 40. To open the first support member 132 of the first support mechanism 130 with respect to the support base material 122, the following operation is performed. From the state of FIG. 2, the arm member 134 of the first lock mechanism 138 is rotated to remove the engagement recess 134b from the fixing pin 127a, and the free end side of the first support member 132 is lifted. Thus, the first support member 132 can rotate around the shaft body 136 of the first shaft support mechanism 137 to expose the intra-identification conveyance path 111P to the outside. Accordingly, it is possible to perform maintenance work such as removing banknotes jammed in the intra-identification transport path 111P or cleaning the sensor facing the intra-recognition transport path 111P. Similarly, in order to open the second support member 142 of the second support mechanism 140 with respect to the support base material 122, the arm member 144 of the second lock mechanism 148 is rotated to move the engagement recess 144b from the fixing pin 127a. Remove and lift the free end side of the second support member 142. Accordingly, the second support member 142 can rotate around the shaft body 146 of the second shaft support mechanism 147 to expose the intra-identification transport path 111P to the outside.

  Next, the operation and effect of the paper sheet identification apparatus 40 according to the present embodiment will be described in comparison with the configuration described in the related art. 5 and 6 are explanatory views for explaining a paper sheet identifying apparatus 200 according to a comparative example corresponding to the conventional technique. FIG. 5 shows a use state of a normal paper sheet identifying apparatus 200, and FIG. The open state of the paper sheet identification apparatus 200 is shown. The paper sheet identification apparatus 200 includes a support base material 222, a support member 230, a lock mechanism 240 that locks the support member 230 with respect to the support base material 222, a support base material 222 that is separated from the intra-identification conveyance path 211P, and A plurality of sensor groups 250 respectively disposed on the support member 230 are provided, and the support member 230 is rotatably supported via a shaft body 232 mounted on the support base material 222. That is, one detection unit or reception unit of each of the sensors 251, 252, and 253 of the sensor group 250 is attached to one support member 230 provided over the entire length of the support base material 222 in the transport direction. In maintenance work of the sensor or the like of the paper sheet identification apparatus 200, as shown in FIG. 6, one support member 230 is rotated about the shaft body 232 to expose the intra-identification conveyance path 211P to the outside. To do.

  Here, the distance from the shaft body 232 to the lock position of the lock mechanism 240 is r1, and the distance from the shaft body 232 to each of the sensors 251, 252, and 253 is d1, d2, and d3. In the state shown in FIG. 5, that is, the support member 230 is locked to the support base material 222 by the lock mechanism 240, the gap gp of the intra-identification transport path 211P is determined. The gap gp depends on the dimensional accuracy of the support member 230, the lock mechanism 240, and the like, and it is assumed that an attachment error of θer is caused as an angle formed by the support member 230 with respect to the support base material 122 arranged in the horizontal direction. To do. Since the gaps gp1, gp2, and gp3 at the positions of the sensors at this time are in a relationship of gp1 = d1sin θer, gp2 = d2sin θer, and gp3 = d3sin θer, gp1> gp2> gp3 as d1, d2, and d3 increase. Become. That is, the gap variation gp increases as the position of the sensor is further away from the shaft body 232. Similarly, a deviation in the conveyance direction with respect to the attachment error θer will be described. Assume that the sensors 251, 252, and 253 are mounted separately above and below the support base material 222 and the support member 230. The side of the sensor 251 that is attached to the support base 222 is located at a distance d1 from the shaft body 232. On the other hand, the portion of the sensor 251 attached to the support member 230 is located at a distance d1 from the shaft body 232 at d1 = cos θer due to the attachment error θer, and the center of the upper and lower sensors of the sensor 251 is Δd1 = d1 ( The center position is separated by 1-cos θer). The same applies to the sensors 252 and 253. As d1, d2 and d3 increase, the deviations Δd1, Δd2 and Δd3 of the upper and lower sensor center positions increase. In order to reduce such a gap gp variation and a sensor center position deviation Δd in the transport direction, the paper sheet identification device 200 according to the present embodiment has the following effects by adopting the above-described configuration.

  7 and 8 are explanatory views for explaining the operation of the paper sheet identification device 40. FIG. 7 shows a normal use state of the paper sheet identification device 40. FIG. 8 shows the opening of the paper sheet identification device 40. Indicates the state. The distance from the shaft body 136 of the first support mechanism 130 to the free end of the first support member 132 is K1, and the distance from the shaft body 146 of the second support mechanism 140 to the free end of the second support member 142 is K2. . The distance from the shaft body 136 to the first sensor 151 is D1, and the distance from the shaft body 146 to the second sensor 152 and the third sensor 153 is D2 and D3, respectively. Furthermore, the distance from the shaft body 136 to the lock position of the first lock mechanism 138 is R1, and the distance from the shaft body 146 to the lock position of the second lock mechanism is R2. In the state shown in FIG. 7, that is, in a state where the first and second support mechanisms 130 and 140 are locked with respect to the support base 122, the gap Gp of the intra-identification conveyance path 111 </ b> P and the vertical center positions of the sensors are displaced. Δd is determined. The gap Gp and the deviation Δd depend on the dimensional accuracy of the first and second support mechanisms 130 and 140, the first and second lock mechanisms 230 and 240, etc., but the first and second support members 132 and 142 are supported by the support base. It is assumed that an attachment error θer is generated as an angle formed with respect to the material 122. At this time, the gaps Gp1, Gp2, and Gp3 at the positions of the respective sensors have a relationship of Gp1 = D1sin θer, Gp2 = D2sin θer, and Gp3 = D3sin θer. Further, the deviations Δd1, Δd2, and Δd3 are in a relationship of Δd1 = D1 (1-cos θer), Δd2 = D2 (1-cos θer), and Δd3 = D3 (1-cos θer). Since the mounting error θer is assumed to be constant, it depends on the sizes of D1, D2, and D3.

  The paper sheet identification device 40 according to the present embodiment reduces the gaps D1, D2, and D3 from the device shown in FIG. 5 so that the gaps Gp1, Gp2, Gp3 and Gp3 can be obtained even with the same mounting error θer. A configuration is adopted in which variations in sensor position deviations Δd1, Δd2, and Δd3 in the transport direction are reduced. In other words, the member on which the sensor group 150 of the paper sheet identification device 40 is mounted is divided into the first and second support members 132 and 142 instead of one member, and each of the support members has the first and second members. The shaft support mechanisms 137 and 147 are provided to be rotatable. As a result, even if a sensor is disposed at the tip of the support member, the distance from the shaft support mechanism to the sensor can be shortened, and variations in gaps in the transport path 111P in the identification and sensor position deviation in the transport direction are reduced in the vicinity of the sensor. Can be made.

  By reducing variations in the gap and sensor position deviation in the transport direction, it becomes easy to keep the level of the signal output from the sensor within a predetermined range, and sensor adjustment and maintenance are facilitated. For example, the sensor output level can be processed in three stages of small, medium, and large corresponding to the mounting position, so that the signal processing can be simplified. In addition, it is possible to simplify the examination of sensor arrangement for absorbing variations in the output level of the sensor. Thereby, it is possible to reduce errors in paper sheet authenticity determination by improving yield by improving production variation and by tightening the algorithm threshold based on the signal level of the sensor.

  Also, the tolerance tolerance of the mechanical parts of the paper sheet identification device 40 for keeping the gap and the sensor position deviation in the transport direction within a predetermined range can be increased. For example, the support base 122 and the first and second locks The tolerance dimensions of the mechanisms 230 and 240 can be increased, and manufacturing is facilitated.

  The first and second support members 132 and 142 can be exposed to the outside within the intra-identification conveyance path 111 </ b> P by being rotated about the shaft support mechanism and opened. At this time, since the free ends of the first and second support members 132 and 142 are arranged to face each other, and a space is formed between them, a wide working space that can access the intra-identification conveyance path 111P can be secured, and a bill or a foreign object can be secured. Etc. can be easily removed. In this case, considering that a human hand or finger can enter, it is desirable that a work space of at least about 50 mm, preferably about 100 mm, be secured.

  FIG. 9 is an explanatory view showing a paper sheet identification apparatus 40B according to the second embodiment of the present invention. This embodiment is characterized by the configuration of the first and second support mechanisms 130B and 140B and the mounting position of the sensor group 150B. The paper sheet identification device 40B includes a support base 122B, a first support mechanism 130B, a second support mechanism 140B, and a sensor group 150B. The first sensor 151B of the sensor group 150B is mounted in the support base material 122B with the intra-identification conveyance path 111P interposed therebetween, and the second sensor 152B includes the first support member 132B of the first support mechanism 130B and the support base material. The third sensor 153B is mounted across the second support member 142B and the support base material 122B of the second support mechanism 140B. The maintenance work of the paper sheet identification device 40B is such that the first and second support members 132B and 142B of the first and second support mechanisms 130B and 140B are rotated around the first and second shaft support mechanisms 137B and 147B. Thus, the intra-identification conveyance path 111P is exposed to the outside.

  According to this embodiment, since the first sensor 151B is fixed only to the support base material 122B, the gap Gp1 due to the attachment error θer and the positional deviation Δd1 in the transport direction with respect to the first sensor 151B relative to the support base material 122B (FIG. 7) does not occur. Moreover, since the first and second support members 132B and 142B are divided into two parts and shortened with respect to the intra-identification transport path 111P of the support base material 122B, the gaps Gp2 and Gp3 attached thereto and the transport Variations in the sensor position deviations Δd2 and Δd3 in the direction can be reduced, so that the signal level of the sensor can be easily managed.

  FIG. 10 is an explanatory view showing a paper sheet identifying apparatus 40C according to the third embodiment of the present invention. This embodiment is a modification of the second embodiment. The paper sheet identification device 40C includes a support base 122C, a first support mechanism 130C, a second support mechanism 140C, and a sensor group 150C. The second sensor 152C of the sensor group 150C is attached to the center sensor mounting portion 122Ca of the support base material 122C. The first and third sensors 151C and 153C are connected to the first and second support members 132C and 142C of the first and second support mechanisms 130C and 140C supported on both sides of the support base 122C, and the support base 122C. It is installed across. According to the third embodiment, similarly to the second embodiment, the second sensor 152C is not attached to the first and second support members 132C and 142C, which are movable members, and is fixed only to the support base material 122C. Therefore, the gap Gp2 of the second sensor 152C with respect to the support base material 122C and the sensor position deviation Δd2 in the transport direction (see FIG. 7) do not vary. In addition, since the first and second support members 132C and 142C are divided into two parts and shortened with respect to the intra-identification transport path 111P of the support base material 122C, the gaps Gp1 and Gp3 attached thereto and the transport Variations in the sensor position deviations Δd1 and Δd3 in the direction can be reduced, so that the signal level of the sensor can be easily managed.

  FIG. 11 is an explanatory diagram showing a paper sheet identifying apparatus 40D according to the fourth embodiment of the present invention. This embodiment is a modification of the third embodiment. The paper sheet identification device 40D is provided with a shaft support mechanism at one end of the support member 122Da in parallel with the transport direction for the support member 122Da having the same configuration as that of the third embodiment, and opens and closes in a direction intersecting the transport direction. It is configured. Thereby, all the conveyance surfaces of the identification device 40D can be accessed. Further, the support members 132D and 142D are provided on the support member 122Da so that the support members in the transport direction are configured without any gaps. Thereby, it is set as the structure which does not produce the danger that the banknote currently conveyed is jammed in the clearance gap between support members. Further, as in the third embodiment, the gap Gp and the sensor position deviation Δd in the transport direction can be reduced, and therefore the signal level of the sensor can be easily managed.

  FIG. 12 is an explanatory view showing a paper sheet discriminating apparatus 40E according to the fifth embodiment of the present invention. This embodiment is a modification of the fourth embodiment. In the paper sheet identification device 40E, one shaft body of the support members 132E and 142E is provided on the support member 122Ea, so that the support members in the transport direction are configured without gaps. Thereby, it is set as the structure which does not produce the danger that the banknote currently conveyed is jammed in the clearance gap between support members. Further, as in the fourth embodiment, the gap Gp and the sensor position deviation Δd in the transport direction can be reduced, so that the signal level of the sensor can be easily managed. In addition, since the number of axial points is smaller than that of the fourth embodiment by providing a common shaft body, the apparatus can be reduced in size.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.
