Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application is based on and hereby claims the benefit under 35 U.S.C. § 119 from European Patent Application No. EP 18165625.7, filed on Apr. 4, 2018, in the European Patent Office. This application is a continuation-in-part of European Patent Application No. EP 18165625.7, the contents of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The invention relates to a presentation device for presenting a ticket, in particular from a printer, such as a thermal printer. 
     BACKGROUND 
     A printer can be fed with a material to be imprinted that is wound up on a wheel. These printers can be used for printing parking tickets or cash register receipts, for instance. For that purpose, along with a printing unit that prints the printing material, the printer has a cutting unit and a presentation device. The cutting unit separates a printed piece of the printing material from the remainder of the printing material, thereby making the printed piece into a ticket. The presentation device presents the ticket to a user and dispenses it to the user. 
     So that the user can be given the ticket, a position on the ticket after its separation until the user takes it, should be controlled by the presentation device. Conventionally, an interception region such as a compartment can be provided as the presentation device, into which region the separated ticket drops. However, that is intensive in terms of structural space, since for instance someone&#39;s hand, or a device, has to reach into the interception region. Moreover, drop direction can be controlled only very poorly, and if the tickets stick in the interception region, a ticket jam can develop. 
     Another known possibility is that the cutting unit does not separate the ticket from the printing material completely but only partially. As a result, the partly separated ticket still hangs from the printing material, and the user can tear off the ticket and take it by himself. However, this has the problem that when a ticket is torn off, the printing material that remains behind the cutting unit can be torn apart or torn off as well. 
     The object of the invention is therefore to create an improved presentation device for presenting tickets. A device is sought for presenting tickets to a user that are completely separated from the remaining printing material but yet that do not drop into a compartment. 
     SUMMARY 
     The invention relates to a presentation device for presenting a ticket that includes a first presentation reel, a second presentation reel that is located directly beside the first presentation reel, a ticket holder, a first housing component in which the first presentation reel and the ticket holder are secured and that is pivotable about a rotating axis and a second housing component. The first housing component has a supporting notch that supports the second presentation reel and that has a first guide edge surface facing away from the rotating axis, a second guide edge surface and a trough. The first guide edge surface extends essentially along a second tangent plane that is perpendicular to a first plane in which the rotating axis is located. The second guide edge surface is inclined toward a second plane that is located in the rotational axis of the second presentation reel and is perpendicular to a third plane that extends through the second presentation reel and the ticket holder. 
     A presentation device for presenting a ticket from a printer includes a first presentation reel, a second presentation reel, a ticket holder and a first housing component. In operation of the device, the first presentation reel contacts a first side of the ticket, and the second presentation reel contacts a second side of the ticket opposite to where the first presentation reel contacts the first side of the ticket. As the ticket advances from the presentation device, gravity pushes the ticket down onto the ticket holder, which is a reel. The first presentation reel, the second presentation reel and the ticket holder are secured in the first housing component. 
     The first housing component is pivotable about a rotating axis and has a supporting notch that supports the second presentation reel. The supporting notch has a first guide edge surface that faces away from the rotating axis, a second guide edge surface, and a trough that extends from a first crossover edge of the first guide edge surface to a second crossover edge of the second guide edge surface. The first guide edge surface coincides with an outer surface of an imaginary cylinder that intersects the first crossover edge and whose rotational axis coincides with the rotating axis. The second guide edge surface, beginning at the second crossover edge, curves towards the first guide edge surface. 
     In one embodiment, the presentation device also includes one or more of a second housing component, a drive unit and a printer. The second housing component is secured nonpivotably relative to the rotating axis. The second housing component maintains the second presentation reel within a spacing above the trough. The second housing component can be located in a different printer region from the rotating axis of the first housing component. The drive unit drives at least one of the first presentation reel, the second presentation reel, or the reel of the ticket holder. The drive unit can include an electric motor or a mechanical coupling to the print cylinder. 
     Other embodiments and advantages are described in the detailed description below. This summary does not purport to define the invention. The invention is defined by the claims.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings. 
       FIG. 1  shows a presentation device  10  that includes has a first presentation reel  11 , a second presentation reel  12  and a third presentation reel  13 . The presentation device  10  is for presenting a ticket  14 . In operation, the first presentation reel  11  is contacted by a first side  15  of the ticket  14 . The second presentation reel  12  is located directly beside the first presentation reel  11  and is axially parallel to the first presentation reel  11 . In operation, the first presentation reel  11  and the second presentation reel  12  simultaneously contact opposite sides of the ticket  14  at a contact point  16 . The first presentation reel  11  and the second presentation reel  12  together define a ticket advancement direction  17  that runs along a first, common tangent plane  18  of the two presentation reels. A ticket holder  19  is spaced apart in the ticket advancement direction  17  from the first presentation reel  11  and additionally is offset from the first tangent plane  18  away from the second presentation reel  12 . 
     The first presentation reel  11  and the ticket holder  19  are attached in a first housing component  32 . The first housing component  32  is pivotable about a rotating axis  20  and has a supporting notch  21  in which the second presentation reel  12  is supported. The supporting notch  21  is composed of a first guide edge surface  22  facing away from the rotating axis  20 , a second guide edge surface  23  that is oriented in V-shaped fashion to the first guide edge surface  22 , and a trough  24  that extends from a first crossover edge  25  of the first guide edge surface  22  to a second crossover edge  26  of the second guide edge surface  23 . The first crossover edge  25  is located at an end of the first guide edge surface  22 , which extends essentially along a second tangent plane  27 . The second tangent plane  27  is perpendicular to a first plane  28  that passes through both the first crossover edge  25  and the rotating axis  20 . The second guide edge surface  23 , beginning at the second crossover edge  26 , inclines at an acute angle from a second plane  29  that passes through the rotational axis  30  of the second presentation reel  12  and is perpendicular to a third plane  31  that extends through the contact point  16  and the ticket holder  19 . 
     The presentation device  10  is used together with a printer, which is not shown in  FIG. 1 . The printer can be a thermal printer. The presentation device  10  enables the user to take the ticket  14  that has been printed by the printer. The user can be either a human or a machine. The first presentation reel  11  and the second presentation reel  12  both contact the ticket  14  during operation of the presentation device  10  and thereby guide the ticket  14  through the presentation device  10  and issue it to the user. The ticket  14  is guided along the ticket advancement direction  17 , which is defined by the first common tangent plane  18  of the first presentation reel  11  and the second presentation reel  12 . The ticket advancement direction  17  is thus essentially the same for each type of ticket  14   s , even if the tickets are of different lengths. This makes it easier for the user to take the ticket  14 . Also as a result, a ticket  14  issuing position at which the ticket  14  is taken by the user can easily be specified for tickets that are of different lengths. 
     The ticket holder  19  serves to ensure that the ticket  14  is supported if it should warp or kink because of its weight. The greater the ticket&#39;s length, or the farther it is transported along the ticket advancement direction  17 , the greater is the force that tries to lower the ticket  14  in the direction of gravity. The tickets can for instance be made from paper or paper-like material, and therefore the ticket  14  can be relatively flexible. The ticket  14  can become bent or drop in operation in the direction of gravity. Because the ticket holder  19  supports the ticket  14 , the ticket  14  issuing position remains essentially the same even for different ticket lengths. This makes it easier for the user to take the ticket  14 . In addition, because the ticket holder  19  is located away from the second presentation reel  12  and offset from the first tangent plane  18 , it is ensured that the ticket holder  19  will not block a transportation path along the ticket advancement direction  17 . Instead, the ticket holder  19  first contacts the ticket  14  when the ticket  14  has dropped somewhat. This enhances the operating safety of the presentation device  10  and reduces the risk of a ticket jam. 
     Because the first housing component  32 , which secures both the first presentation reel  11  and the ticket holder  19 , is pivotable about the rotating axis  20 , the first housing component  32  can assume at least two positions. A first position is an operating position, and a second position is a maintenance position. In the operating position, the first housing component  32  is arranged for conveying the ticket  14 , presenting it, and issuing it to the user. In the maintenance position, the first housing component  32  is pivoted open about the rotating axis  20 , thereby providing access to the printer or the presentation device  10 . The pivotablility of the first housing component  32  makes maintenance of the printer or the presentation device  10  easier. In the event that a printer with the presentation device  10  is in a continuous operation mode, a new amount of printing material must be replenished relatively often. For that purpose, the new printing material must be repositioned through all the relative components of the printer, including through the presentation device  10 . Pivoting the first housing component  32  into the maintenance position allows easier access to the presentation device  10  and to the printer, thus making replacement of the printing material easier. Moreover, the printing material can be guided along the components faster, thus saving time. Once the printing material has been replaced, the first housing component  32  can be pivoted relatively easily back into the operating state, and the printer with the presentation device  10  can put back into operation. Additionally, the individual components of the presentation device  10 , such as the first presentation reel  11  or the ticket holder  19  can be more easily replaced in the maintenance position. 
     Because the first housing component  32  has a supporting notch  21  that supports the second presentation reel  12 , all of the components of the presentation device  10  that guide the ticket  14  are secured by means of the first housing component  32 . This makes the handling of the presentation device  10  easier. 
     The first presentation reel  11  is rotatably supported in the first housing component  32 . The second presentation reel  12  is rotatably supported in the supporting notch  21  of the first housing component  32 . In addition, the second presentation reel  12  can move along the guide edge surfaces of the supporting notch  21  and between them. 
     The supporting notch  21  enables a translatory movement of the second presentation reel  12  along the guide edge surfaces and between them. In operation of the presentation device  10 , any difference in thickness of the ticket  14  or warping of the ticket  14  that may occur can be compensated for by this movement of the second presentation reel  12 . During the translatory movement of the second presentation reel  12 , the first presentation reel  11  and the second presentation reel  12  stay in contact with the ticket  14 . In operation, in order to maintain the contact of the second presentation reel  12  with the ticket  14 , a prestressing mechanism with a spring, or some other mechanism can be used in addition to gravity. 
     Because the second guide edge surface  23  beginning at the second crossover edge  26  is inclined toward the second plane  29 , any movement of the second presentation reel  12  up the second guide edge surface  23  is impeded. A ticket  14  that has dropped onto the ticket holder  19 , and whose center of gravity in the advancement direction  17  is located downstream of the ticket holder  19 , exerts a force on the second presentation reel  12  because of the stiffness of the ticket  14  and because the pivot point of the force is located at the ticket holder  19 . This force on the second presentation reel  12  is directed towards the second guide edge surface  23 , which impedes any movement of the reel  12  resulting from the force. Because the movement resulting from the force is impeded, the ticket  14  is retained by the presentation device  10  and will not slip away. Even if the ticket  14  is relatively long, it is retained by the presentation device  10  until the user takes it. The second guide edge surface  23  thus enables advantageous retention of the ticket  14 , even with tickets of varying lengths. 
     The contact point  16  is the location on the second presentation reel  12  that is contacted by the second side  33  of the ticket  14  in operation. The contact point  16  is preferably a linear contact. In another embodiment, the contact point  16  is composed of a plurality of regions on the second presentation reel  12  that are contacted by the second side  33  of the ticket  14  in operation. The contact point  16  can also be reduced to a plurality of point-like regions that are contacted in operation by the second side  33  of the ticket  14 . The distance between contact points on third plane  31  can thus be stretched by the linear contact with the ticket holder  19 , or by the regions on the second presentation reel  12  that are contacted in operation by the second side  33  of the ticket  14  with the ticket holder  19 , or by the point-like regions on the second presentation reel  12  that are contacted in operation by the second side  33  of the ticket  14  with the ticket holder  19 . 
     The ticket holder  19  can be formed for instance by a strip, stop or other component that in operation is contacted by the ticket  14 . The ticket holder  19  is the region on the strip, stop, or other component that is contacted in operation by the ticket  14 . The region can for instance be two-dimensional, linear, or point-like. 
     Because the first guide edge surface  22  extends essentially along the second tangent plane  27 , it is possible for the second presentation reel  12  to remain unpivoted, while the first housing component  32  along with the first presentation reel  11  and the ticket holder  19  is pivoted from the operating position into the maintenance position. The second presentation reel  12  can, during the pivoting, slide along the first guide edge surface  22  without essentially changes its position. The second presentation reel  12  can be held during the pivoting of the first housing component  32  by means of an additional component or by the user. The first guide edge surface  22  thus enables the advantageous pivoting of the first housing component  32  while simultaneously the second presentation reel  12  stays in the same position. This makes the maintenance and handling of the presentation device  10  easier. 
     The first guide edge surface  22 , beginning at the first crossover edge  25 , extends within a guide edge surface region that stretches from a plane that, relative to the second tangent plane  27 , is rotated about the sectional axis between the second tangent plane  27  and the first plane  28  by more than 25 degrees, to another plane which relative to the second tangent plane  27  is rotated about the sectional axis between the second tangent plane  27  and the first plane  28  by minus 25 degrees. The shape of the first guide edge surface  22  can for instance be planar or curved or a combination of the two. The guide edge surface region can also be formed by two planes parallel to the second tangent plane  27 , of which planes one is spaced apart from the second tangent plane  27  by plus ten millimeters and of which the other is spaced apart from the second tangent plane  27  by minus ten millimeters. 
     In summary, the supporting notch  21  thus has the effect that movement of the second presentation reel  12  is made possible to equalize the thickness of the ticket  14 . However, additional movement of the second presentation reel  12  resulting from the force of the ticket rigidity is impeded. Thus, the maintenance of the presentation device  10  is made easier. Presenting the ticket  14 , issuing the ticket  14 , and maintaining the presentation device  10  is considerably facilitated by the combination of the pivotable first housing component  32 , the supporting notch  21 , and the locations of the first presentation reel  11 , the second presentation reel  12 , and the ticket holder  19 . The presentation device  10  thus considerably improves the presentation and issuance of the ticket  14 . 
     The presentation device  10  has a second housing component  34  that is secured nonpivotably relative to the rotating axis  20 . The second housing component  34  guides the second presentation reel  12  with a spacing  35  that extends from the second housing component  34  to the second presentation reel  12 . The spacing  35  can vary along the second housing component  34 . The second housing component  34  can for instance be located in a different printer region from the rotating axis  20  of the first housing component  32 . As a result, the pivoting of the first housing component  32  is not impaired by the second housing component  34 . The second housing component  34  can have a protrusion  36  that guides the second presentation reel  12  with the spacing  35  that extends from the protrusion  36  to the second presentation reel  12 . The second housing component  34  can also have a recess  37  in which the second presentation reel  12  is located. The spacing  35  between the second housing component  34  and the second presentation reel  12  should be selected such that a desired movement, which is made possible by the first guide edge surface  22  and the second guide edge surface  23 , of the second presentation reel  12  is unimpaired, yet at the same time the second presentation reel  12 , upon pivoting of the first housing component  32 , is retained and thus does not swivel along with that housing component. The second housing component  34  can thus make the handling and maintenance of the presentation device  10  easier. 
     The first side  15  of the ticket  14  that is contacted in operation of the presentation device  10  has an adhesive layer. The adhesive layer allows the ticket  14  that is taken from the presentation device  10  to be directly glued onto a device by the user. For instance, the ticket  14  with the adhesive layer can be immediately glued onto a product that is to be labeled. When the ticket  14  and the printing material have the adhesive layer, guiding the printing material or the ticket  14  through the printer and through the presentation device  10  in operation is more complicated because the adhesive layer contacts components and as a result the printing material or the ticket  14  can stick to the components. The printing material that has the adhesive layer can be a so-called “linerless printing material” or “linerless paper”. 
     Because the ticket  14  or the printing material have the adhesive layer on the first side  15 , in operation the adhesive contacts the first presentation reel  11  and the ticket holder  19  of the presentation device  10 . It is also conceivable that the ticket  14  has the adhesive layer on the second side  33 . 
     The ticket holder  19  preferably has a third presentation reel  13  that in operation contacts the ticket  14 . Thus, in some embodiments, the ticket holder  19  is formed by the third presentation reel  13 . The third presentation reel  13  can be designed similarly to the second presentation reel  12  or to the first presentation reel  11 . The third presentation reel  13  can be supported rotatably in the first housing component  32 . Because the ticket holder  19  has a third presentation reel  13 , in operation the ticket  14  is not scraped as it moves along the ticket holder  19 . Instead, the ticket  14  can move along with the rotating third presentation reel  13 . The advancement direction  17  and issuance of the ticket  14  are therefore more uniform and fluid. This prevents a jam and improves the presentation and issuance of the ticket  14 . When the ticket  14  has the adhesive layer on the first side  15 , the adhesive layer contacts the third presentation reel  13  during operation of the presentation device  10 . A ticket  14  with an adhesive layer that scrapes on the ticket holder  19  in operation would easily lead to sticking or unwanted accumulations of adhesive. This can be reduced or avoided by means of the third presentation reel  13 . The operation of the presentation device  10  is thus improved even with tickets that have an adhesive layer. 
     In one embodiment, the presentation device  10  has no separate drive unit for rotationally driving the first presentation reel  11  and/or the second presentation reel  12  and/or the third presentation reel  13 . The advancement movement of the ticket  14  or of the printing material in operation can be achieved using other components of the printer, such as a print cylinder. 
       FIG. 2  shows that the first presentation reel  11  has a first shaft  38 , on which a plurality of first rings  39  are arranged spaced apart from one another. The second presentation reel  12  has a second shaft  40  on which a plurality of second rings  41  are located spaced apart from one another. And the third presentation reel  13  has a third shaft  42  on which a plurality of third rings  43  are arranged spaced apart from one another. 
     In operation, the rings  39 ,  41 ,  43  contact the ticket  14 . The shafts  38 ,  40 ,  42  are rotatably secured in the first housing component  32 , and the respective rings  39 ,  41 ,  43  are fixedly connected to the respective shafts. However, the rings can also be rotatably attached to the respective shafts. The spacing between the various rings on the same shaft can also vary. 
     In operation, the contact between the ticket  14  and the presentation reels could potentially extend over the entire length of each presentation reel. This large-area contact, particularly with tickets that have an adhesive layer, can lead to unwanted sticking of the ticket to the reel. Reducing this large-area contact can counteract this problem. Because the rings  39 ,  41 ,  43  are arranged on the respective shafts  38 ,  40 ,  42  spaced apart from one another, and only the rings contact the ticket  14  in operation, the contact of the ticket with the various presentation reels is interrupted and thereby reduced. The presentation and issuance of the ticket  14  by the presentation device  10  can thereby be facilitated and improved. 
     At least one of the rings, in the cross-sectional plane in which the ring&#39;s rotational axis is located, has an outwardly arched cross section. Because at least one of the rings has the outwardly arched cross section, a point contact is established during operation between the ticket  14  and the ring. As a result, the overall cross-sectional contact area between the ticket and the ring is reduced to a point contact. The presentation and issuance of the ticket  14  by the presentation device  10  is thereby further facilitated and improved, especially if the ticket  14  has the adhesive layer. 
     The first rings  39  on the first shaft  38  are offset from the second rings  41  on the second shaft  40  such that the rings can overlap one another from the side perspective of  FIG. 1 . Similarly, the first rings  39  on the first shaft  38  are offset from the third rings  43  on the third shaft  42 . Moreover, the second rings  41  on the second shaft  40  are offset from the third rings  43  on the third shaft  42 . The offset locations of the rings allow for overlapping in the plane orthogonal to the shaft axes and reduce the structural space needed to accommodate the individual presentation reels in the first housing component  32 . The presentation device  10  can as a result be more compact. Furthermore, the spacing between the rings can be adapted such that in operation the advancement motion of the ticket  14  is more fluid, which improves the presentation and issuance of the ticket  14 . Moreover, because the spacing of the second rings  41  is offset relative to the spacing of the third rings  43 , the ticket  14  is prevented from rolling away and separating from the first rings  39  because the third rings  43  represent an additional structural barrier. This improves the operating safety. 
     At least one of the first rings  39 , second rings  41  and/or third rings  43  has an anti-adhesive surface  44  that in operation contacts the ticket  14 . All of the rings could have the anti-adhesive surface  44 . The anti-adhesive surface  44  reduces the adhesion of the rings to the ticket  14 . As a result, an advantageous presentation and issuance can be achieved during continuous operation, especially for a ticket  14  that has an adhesive layer. Furthermore, cleaning a coated anti-adhesive surface is easier than cleaning an uncoated surface. This facilitates maintenance of the presentation device  10 . At least one of the presentation reels could also have the anti-adhesive surface  44 . 
     In one embodiment, the anti-adhesive surface  44  includes polytetrafluoroethylene (PTFE), chemically (C2F4)n, which is also known by the trade name “Teflon”. The rings that have an anti-adhesive surface made of polytetrafluoroethylene (PTFE) reduce the adhesive effect of the various rings with the ticket  14 . 
     In one embodiment, the first guide edge surface  22  of the supporting notch  21  is not planar but rather coincides at least partially with the outer surface of an imaginary cylinder that intersects the first crossover edge  25  and whose rotational axis coincides with the rotating axis  20 . The shape of the first guide edge surface  22  is thus at least partially that of the imaginary cylinder whose rotational axis coincides with the rotating axis  20 . If the first housing component  32  is rotated about the rotating axis  20 , the absolute position of the second presentation reel  12  can remain unchanged because the second presentation reel  12  can move along the first guide edge surface  22 , whose shape coincides with that of the imaginary cylinder. As a result, the pivoting of the first housing component  32  from the operating position to the maintenance position is especially simple, and the handling and maintenance of the presentation device  10  are simplified. 
     In one embodiment, the second guide edge surface  23 , beginning at the second crossover edge  26 , has a partially concave curved shape relative to that of the first guide edge surface  22 . Thus, the second guide edge surface  23 , beginning at the second crossover edge  26 , curves towards the first guide edge surface  22 . The curvature can increase with increasing distance from the second crossover edge  26 . In operation, the curved shape has the effect that an increasing deflection of the second presentation reel  12  resulting from a force  45  directed away from the contact point  16  increases the impedance against that force. The greater the deflection of the second presentation reel  12 , the more that any additional movement of the second presentation reel  12  is impeded due to the curved shape of the second guide edge surface  23 . The impedance is applied as a function of the length of the ticket  14  and of the resulting force  45 . As a result, tickets that are especially long can be advantageously presented, held and issued in operation. 
     The first housing component  32  has a housing component recess  37  defined by the first guide edge surface  22 , the trough  24 , and the second guide edge surface  23 . Because of the housing component recess  37 , the first housing component  32  is open in a region that extends from the first guide edge surface  22  to the second guide edge surface  23 . As a result, the second presentation reel  12  can easily be removed from the first housing component  32  or inserted into the supporting notch  21  of the first housing component  32 . Maintenance and handling of the presentation device  10  are thereby made easier. 
     The presentation device  10  includes a drive unit that is arranged for rotationally driving the first presentation reel  11 , the second presentation reel  12  and/or the third presentation reel  13 . The presentation reels can for instance be rotationally driven using an electric drive. The presentation reels could also be rotationally driven using a mechanical coupling with the print cylinder. The drive of each individual presentation reel can be derived from the drive of the print cylinder, so that an optimal advancement of the ticket  14  is made possible. The presentation reels can be braked or stopped by controlling the drive. As a result, it is possible to counteract unwanted slipping or uncontrolled rolling away of the ticket  14  during operation. 
     The printer to which the presentation device  10  is associated can be a thermal printer. The presentation device  10  can also be a retrofitting solution for existing printers. 
       FIG. 1  shows that the presentation device  10  for presenting a ticket  14  includes a first presentation reel  11 , a second presentation reel  12 , a third presentation reel  13 , a first housing component  32 , and a second housing component  34 . The third presentation reel  13  serves as a ticket holder  19  in one embodiment. The first presentation reel  11  is oriented axially parallel the second presentation reel  12  and is located directly adjacent to the second presentation reel  12 . The ticket  14  has a first side  15  and a second side  33 . In operation of the presentation device  10 , the first presentation reel  11 , the second presentation reel  12 , and the third presentation reel  13  all contact the ticket  14 . The first side  15  of the ticket  14  is contacted by the first presentation reel  11  and the third presentation reel  13 , and the second side  33  of the ticket  14  is contacted by the second presentation reel  12 . The first presentation reel  11  and the second presentation reel  12  simultaneously contact opposite sides of the ticket  14  at the same location. The rotation of the first presentation reel  11  and the second presentation reel  12  cause the ticket  14  to move in the ticket advancement direction  17 . The ticket advancement direction  17  runs along a first tangent plane  18 , which is the common tangent plane of both the first presentation reel  11  and of the second presentation reel  12 . The ticket advancement direction  17  extends from right to left in  FIG. 1 , beginning at a cutting unit of a printer (not shown) through the presentation device  10  to an issuing position at the left at which a user can take the ticket  14 . The third presentation reel  13  is spaced apart in the ticket advancement direction  17  from the first presentation reel  11  and is additionally offset under the first tangent plane  18  and away from the second presentation reel  12 . Because the circumference of the third presentation reel  13  is offset below the first tangent plane  18 , the ticket  14  contacts the third presentation reel  13  only after the ticket  14  has dropped due to the force of gravity acting on it. 
     The first presentation reel  11  rotates about a first rotational axis  46 ; the second presentation reel  12  rotates about a second rotational axis  30 ; and the third presentation reel  13  rotates about a third rotational axis  47 . The first presentation reel  11  and the third presentation reel  13  are supported rotatably about their rotational axes  46 ,  47  by the first housing component  32 . 
     The first housing component  32  is pivotable about a rotating axis  20 . The first housing component  32  includes a supporting notch  21  that supports the second presentation reel  12 . The supporting notch  21  has a trough  24  remote from the rotating axis  20 , a first guide edge surface  22  and a second guide edge surface  23  that is arranged in V-shaped fashion relative to the first guide edge surface  22 . The trough  24  is at the bottom of the “V” shape. The trough  24  extends from a first crossover edge  25  of the first guide edge surface  22  of the trough  24  as far as a second crossover edge  26  of the second guide edge surface  23  of the trough  24 . The first guide edge surface  22  and the second guide edge surface  23  thus jointly form the “V” shape in the cross section that is orthogonal to the first rotational axis  46 . The second presentation reel  12  is supported in the supporting notch  21  such that it can move both rotationally and translatorally. In its resting position, the second presentation reel  12  is supported in the trough  24 . The trough  24  is formed by a partial cylindrical groove between the surfaces of the first guide edge surface  22  and the second guide edge surface  23 . Alternatively, the cross section of the trough  24  is not a portion of a circle but rather a portion of some other geometric shape, such as a rectangular parallelepiped or an ellipse. In operation of the presentation device  10 , the second presentation reel  12  can move along the first guide edge surface  22  and the second guide edge surface  23  and in the region between them. 
     The first guide edge surface  22  extends away from the first crossover edge  25  along a second tangent plane  27  that is perpendicular to a first plane  28  through which the rotating axis  20  and the first crossover edge  25  pass. If the first housing component  32  is pivoted about the rotating axis  20  counter-clockwise in  FIG. 1 , then because of the orientation of the first guide edge surface  22 , the second presentation reel  12  can maintain its absolute position (its prior resting position) by traveling along the first guide edge surface  22  if the second presentation reel  12  is retained at that absolute position by a user or by the second housing component  34 . 
     The second guide edge surface  23  is inclined at an acute angle between the second crossover edge  26  and a second plane  29  that passes through the second rotational axis  30  and is perpendicular to a third plane  31 . The third plane  31  passes through both the contact point  19  at which the ticket  14  contacts the third presentation reel  13  and the contact point  16  at which the ticket  14  contacts both the first presentation reel  11  and the second presentation reel  12 . The third plane  31  deviates from the first tangent plane  18  in that the contact point  19  is offset below the first tangent plane  18 . A force  45  acting on the second presentation reel  12  in a direction away from the contact point  16  would push the reel  12  towards the second guide edge surface  23 , which would impede any movement of the reel  12  due to the inclination of the second guide edge surface  23 . 
     In one embodiment, the first presentation reel  11  includes a first shaft  38  to which the first rings  39  attached. The first rings  39  are spaced apart from one another on the first shaft  38 . The second presentation reel  12  includes a second shaft  40  to which the second rings  41  are attached. The second rings  41  are also spaced apart from one another on the second shaft  40 . The third presentation reel  13  includes a third shaft  42  to which third rings  43  are attached, which are spaced apart from one another. In operation of the presentation device  10 , only the rings  39 ,  41 ,  43  contact the ticket  14 . As a result, contact between the various presentation reels  11 ,  12 ,  13  and the ticket  14  is reduced. 
     The second housing component  34  is secured nonpivotably about the rotating axis  20 . Furthermore, the second housing component  34  has a recess into which the second shaft  40  of the second presentation reel  12  passes. On the second housing component  34 , the recess forms a protrusion  36 , which includes the second shaft  40 , in part with a spacing  35  that extends from the protrusion  36  as far as the second shaft  40 . When the first housing component  32  is pivoted clockwise about the rotating axis  20 , the spacing  35  is reduced to zero. As a result, the protrusion  36  contacts the second shaft  40 , and the second presentation reel  12  is retained such that it can no longer pivot about the rotating axis  20 . 
     As can be seen particularly from  FIG. 2 , the rings  39 ,  41 ,  43 , in a plane in which their respective rotational axis is located, have an outwardly arched cross section. The contact of the ticket  14  with the respective presentation reels  11 ,  12 ,  13  is as a result reduced, for each of the rings  39 ,  41 ,  43 , to a point contact. 
       FIG. 2  shows that the first rings  39  on first shaft  38  are offset relative to the second rings  41  on second shaft  40 . Furthermore, the first rings  39  on first shaft  38  are offset relative to the third rings  43  on third shaft  42 . The second rings  41  on second shaft  40  are also offset relative to the third rings  43  on third shaft  42 . As a result of the rings being offset from one another, the first presentation reel  11  and the third presentation reel  13  can overlap from the side perspective of  FIG. 1  such that the reels are arranged in a space-saving manner side-by-side with one inside the other. The rings  39 ,  41 ,  43  have an anti-adhesive surface  44 , which when the presentation device  10  is in operation contacts the ticket  14 . The anti-adhesive surface  44  can include or even be made of Teflon and/or silicon. 
     From the drawings, it can furthermore be seen that the first housing component  32  has a housing component recess  37 . The housing component recess  37  is defined by the first guide edge surface  22 , the trough  24 , and the second guide edge surface  23 . The housing component recess  37  forms an opening of the first housing component  32  that allows the second presentation reel  12  to be easily placed in the supporting notch  21 .
