Description

Cashbox with a counter-pressure unit comprising a torsion spring and / or mainspring

The invention relates to a cash box comprising a ^¬ On receiving area for receiving a banknote stack, the banknotes are mechanically fed to the receiving area in a tray ^¬ direction. Further, the Geldkas ^¬ sette means disposed in the receiving area, in storage ^¬ direction and opposite to the offset direction movable counter-pressure unit for applying a directed opposite to the offset direction back pressure force to a in the Aufnahmebe ^¬ rich recordable value note stack. In addition, an elastic element is provided, which biases the Gegendruckein ^{¬ unit} against the deposit direction for generating the counter-pressure force. Furthermore, the invention relates to such a counter pressure unit for cash boxes.

The notes of value received in cash cassettes are added to the cash cassettes in the form of a value note stack, with the notes of value contacting each other with their front and / or back sides. The bank notes are in this case the receiving area fed by means of feeding and / or removing modules from the head side of the cashbox ^¬ and / or removed. In this case, newly supplied notes of value are pressed against the front side of the value banknote already recorded in the cashbox. In order to enable a secure, reliable depositing of the newly added notes of value, it is necessary that the notes already taken up are held in the stacked form and do not slip or tilt over one another. For this purpose Ge ^¬ gendruckeinheit are often provided in known cash boxes, with the help of the already recorded Wertscheinstapel contrary to the deposit direction are fed to the newly added notes of value, is biased ^¬ so that the value note stack is always kept from both sides under a required pressure, are such that the banknotes of the banknote stack bundled together ^¬ quantitative hold.

For this purpose, it is necessary that this counter-pressure unit according ^¬ weils moved according to the amount of recorded notes of value in the offset direction or opposite to the offset direction. A known way to do this is to move the counter-pressure unit using a drive unit in ^¬ play as a motor, according to the filing Rich ^¬ for, or opposition to the filing direction. The disadvantage of this is that such structures are complex and require appropriate control. Furthermore, such counter-pressure units moved by drive units require a large number of sensors and actuators in order to reliably apply the necessary counter-pressure force. As a result, the production is costly and expensive.

In addition, the force acting on the counterpressure unit by the value stack increases the more notes of value the value note stack comprises. Is generated by the drive unit standardized always produces the same counter-pressure force, this has the consequence that the pressing force, new supply ^¬ de banknotes are fed to the banknote stack against the order is smaller, the more notes of value are received ^¬ range already in the receptacle.

Another possibility is to attach the counterpressure unit via pressure or tension springs on a bottom element of the cashbox, so that the counterpressure force is applied via these train ^¬ or compression springs. Such a cashbox is known for example from German Patent Application 10 2011 000 790.3. The disadvantage of this is that this space-consuming and prone to errors, since the open arranged in the cash box pressure or tension springs can be moved by contact with others in components and / or in the handling of the cashbox from its predetermined position.

It is an object of the invention to provide a cashbox and a counter-pressure unit for cash boxes, with the help of a reliable, secure deposit of notes in the cashbox is possible.

This object is achieved by a cash box with the Merkma ^¬ len of claim 1 and by a counter-pressure unit with the features of claim 15. Advantageous further ^¬ formations of the invention are specified in the dependent claims. According to a first aspect of the invention, the elastic ^¬ cal element comprises a torsion spring which is arranged on the counter-pressure unit. This has on the one hand the advantage that the back pressure force is applied purely passive, meaning that we ^¬ of the sensors, an electrical control is necessary a driving unit still yet. Thus, a particularly cost-effective, space-saving and low-maintenance construction is achieved. Moreover, such a spring has the advantage that the force applied by their counter-pressure force will be greater, the more notes of value of the recorded value note stack, comprising so depositing the newly supplied value ticket ^¬ ne always against the same force takes place, so that a particularly safe, reliable and uniform storage of notes of value is guaranteed in the storage direction.

Compared with compression and tension springs, the provision of a torsion spring directly on the counter-pressure unit has the advantage that a particularly compact and space-saving design is achieved. The torsion spring is always moved together with the counter-pressure unit in the storage direction or against the storage direction and is not, such as compression or tension springs, attached only at one end to the counter-pressure unit and with the ^¬ end to the housing. Thus, the error rate is reduced.

According to a second aspect of the invention, a mainspring is provided instead of the torsion spring. This has, in addition to the above with respect to the torsion spring po- The advantages that a drive spring significantly less space than a torsion spring needed because it is much more compact in the direction of its longitudinal axis. In addition, the necessary for transmitting the torque attachment of the spring in a drive spring can be made easier than a torsion spring. Shaft springs are often referred to as coil springs.

The mainspring comprising in particular a in a plane spi ^¬ ralförmig coiled metal strip. One of the ends of the metal strip is preferably attached to a shaft of the counter ^¬ pressure unit, wherein the other end is fixed relative to a housing of the counter pressure unit, so that the mainspring is either curious or relaxed upon rotation of the shaft depending on the direction of rotation. The attached to the shaft end is inserted in particular in a groove of Wel ^¬ le.

The cash box comprises, in particular, a supply unit, via which notes of value supplied in a feed direction of the cash box are fed into the storage area in the depositing direction. Here, in particular via the At ^¬-in unit and a redirection of bank notes from the To ^¬ insertion direction into the actual filing direction. The feed unit is arranged in particular in a head region of the cashbox. The counterpressure unit can in particular ^¬ sondere in the entire recording area, ie from the feed unit to the feed unit one entgegenge ^¬ translated housing part of a housing of the cash box to be moved. The counterpressure unit preferably has at least one recess in which the torsion spring and / or mainspring is at least partially, preferably completely, accommodated. In particular, the counter-pressure unit has a housing which at least partially, preferably completely, surrounds the torsion spring and / or the mainspring. Thus, a more secure mounting of the torsion spring and / or mainspring is achieved and avoided that this comes into contact with other elements of the cashbox and / or notes of value when moving the counter pressure unit. This prevents ^ver¬ that the torsion spring and / or mainspring could be disturbed, so that a reliable operation of the counter pressure unit is guaranteed.

In a particularly preferred embodiment, the torsion spring and / or mainspring is enclosed on all sides by the housing, so that it is protected by the housing and thus is not exposed to environmental influences.

In the receiving area, at least one extending in the storage direction first rack is arranged. The counter ^¬ pressure unit has at least a first gear whose Zah ^¬ tion engages the toothing of the first rack and with the aid of which the counter pressure unit is mounted on the first rack. In a particularly preferred embodiment, in the cashbox at least one second rack is provided, the counter-pressure unit has a second gear wheel which meshes with the teeth of the second rack and the ers ^¬ th gear. This ensures that the Ge ^¬ gendruckeinheit is stored for a reliable on the housing of the cashbox, but on the other hand in a simple manner in the depositing direction and against the storage direction is movable.

In a particularly preferred embodiment is in the receiving area on the side opposite to the side on which the first rack is disposed is opposite min ^¬ least arranged extending in the offset direction third gear rack ^¬ ge. The counter-pressure unit comprises at least a third gear whose teeth engage in the toothing of the third rack and with the aid of which the counter-pressure ^¬ unit is mounted on the third rack.

Furthermore, the cash box may have a fourth rack and the counter-pressure unit a fourth gear, wherein the fourth gear meshes with the teeth of the fourth rack and with the third gear. Thus, connected at both ends ^¬ term storage of the counter-pressure unit is achieved on the two side walls of the cash box so that the back pressure ^¬ unit is guided uniformly in the offset direction and opposite to the offset direction and in particular a tilting and / or tilting is avoided. In particular, by meshing the first gear with the second gear and meshing the third gear with the fourth gear ensure that the meshing gears are turned evenly. The second gear and the fourth gear are in particular connected to one another via a shaft, wherein the two gears are each rotatably disposed on this Wel ^¬ le. Thus, all four gears mitei ^¬ nander engaged so that they evenly turned ^¬ who and thus the counter pressure unit is moved by the guide on the four racks in the storage direction and against the storage direction, without this ver ^¬ tilt and / / or twist.

The torsion spring and / or mainspring is in particular so coupled to the first gear that the torsion spring and / or mainspring is tensioned in a first rotational direction upon rotation of the first gear. This ensures that the torsion spring and / or mainspring is all the more tensioned, the more the first gear is rotated and thus the more the counter-pressure unit is moved in the direction of deposit. Thus, the applied on the torsion spring and / or driving force back pressure force increases all the more, the more bank notes are received in the receiving portion, so that the erzeug ^¬ te by the weight of the banknote stack weight force is balanced, and the force applied for supplying a new value certificate regardless of the number of recorded banknotes is always about the same.

It is particularly advantageous if the torsion spring and / or mainspring is so coupled to the first gear that the torsion spring upon rotation of the first gear is relaxed in a first direction of rotation opposite second direction of rotation. The second direction of rotation is in this case in particular that direction of rotation in which the gearwheel is rotated when the counterpressure unit moves ent ^¬ against the deposit direction. This ensures that, when a bill of exchange is removed from the bill of stock, the counterpressure unit is moved back against the deposit direction over the force applied by the torsion spring and / or mainspring backpressure unit and thus the value ^¬ apparent stack is raised against the deposit direction, so that removed more notes of value at any time or can be supplied with the same force.

The first rotational direction of the gear is the one rotary ^¬ direction in which the gear is rotated, if a value ^¬ translucent is supplied. When the value certificate is fed in, the value note is pressed against the front side of the already received ^value card stack. By this ^¬ be applied force the platen unit is moved into the tray Rich ^¬ tung against the restoring force of the torsion spring and / or driving force, so that the banknote is fed to the receiving area. About the engagement with the first rack while the gear is moved in the first direction of rotation.

The first gear is in particular in such a manner with the first rack in engagement that the first gear is rotated when moving the counter-pressure element in the depositing direction in the first direction of rotation and when moving counter to the direction of deposition in the second direction. Furthermore, it is advantageous if the torsion spring comprises a wound wire having a first end and a second end. The torsion spring is supported on the housing via the first end and is coupled to the first gear via the second end in such a way that the second end is rotated upon rotation of the first gear.

The first gear is in particular rotatably mounted on a shaft, wherein the second end of the wire is fixed to this shaft, so that upon rotation of the first Zahnra ^¬ des and thus rotating the shaft, the second end of the wire is rotated, so that the Torsion spring is twisted accordingly and thus the counter-pressure force is increased. Thus, a particularly simple and yet reliable construction is given.

In particular, the shaft has a hole into which the two ^¬ te end of the wire is inserted. This allows ei ^¬ ne particularly simple installation of the counter pressure unit.

In an alternative embodiment of the invention, the third gear can be such coupled to the torsion spring, that upon rotation of the third gear in Dieje ^¬ nige direction in which the third gear wheel in feeding notes of value, that is, rotated in the shift direction when moving the counter-pressure unit is, the torsion spring is also twisted and thus the counter-pressure force is increased. In a further alternative embodiment, it is also possible that a plurality of torsion springs and / or mainspring are provided, wherein the torsion springs and / or mainspring are each coupled to one of the gears.

In particular, a torsion spring and / or mainspring is used whose characteristic curve is designed in such a way that the increase of the applied counterpressure force by supplying a bill approximately corresponds to the weight of this bill of exchange, so that the force applied to supply additional notes of value to the receiving region must always be about the same force. With this, the feed unit must always press the new notes of value to be fed with the same force against the face of the value ^¬ apparent stack.

Another aspect of the invention relates to a counter-pressure unit for cash cassettes which comprises an elastic member for biasing the counter-pressure unit against an offset direction for generating a counter-pressure force if the counter-pressure unit is inserted into a cashbox on ^¬. The elastic element comprises at least one arranged on the counter-pressure unit torsion spring and / or drive ^¬ spring. The counter-pressure unit can be further developed in particular with the previously in connection with the counter-pressure unit of the cashbox be ^¬ advertised features.

Further features and advantages of the invention will become apparent from the following description, which explains the invention in conjunction with the accompanying figures.

FIG. 12 shows a schematic, perspective representation of a section of the counterpressure unit according to FIGS. 10 and

1 shows a schematic, perspective illustration lung ^¬ a cashbox 10 for receiving notes of value according to a first embodiment is shown. Here, parts of the housing 12 of the cashbox 10 are ausgeblen ^¬ det, so that the internal components are more visible.

In the embodiment shown in Figure 1 cashbox 10 is a pure deposit box, meaning that the Geldkas ^¬ sette 10 is used exclusively to store of value and the stored value coupons will not ma ^¬ schinell taken back for a withdrawal of the cashbox 10th Alternatively, it may, at the cashbox 10 but also be a recycled cartridge, meaning that fed the cashbox 10, both banknotes than the can as ^¬ be removed. Furthermore, the cashbox 10 can also be a pure cashout cassette, ie the recorded banknotes are taken exclusively but no new banknotes are mechanically fed. The banknotes can be both banknotes and checks, with the Size of the cashbox can be adjusted according to the recorded notes of value.

The cash box 10 comprises a supply unit 14, via which notes of value mechanically fed to the cash box 10 can be supplied to a receiving area 16 of the cash box 10 for receiving a value note stack. The delivery unit 14 illustrated purely schematically ^¬ schematically here is so formed from ^¬ as to move the notes of value in an offset direction PI in the receiving area 16, wherein the bank notes are in this case moved with its front or rear side first into the on ^¬ receiving region 16, so that the notes of value in an operational arrangement of the cash box 10, as shown in Figure 1, with their front and rear sides rest on each other. The cash box 10 is particularly intended for vertical use in a bill handling apparatus.

A counter-pressure unit 100 is provided in the receiving area 16, the value-added stack accommodated in the receiving area 16 being accommodated in the area between this counter-pressure unit 100 and the feed unit 14. By the counter-pressure unit 100 is, as will be described in more detail below, directed against the deposition direction PI counter-pressure force on the value note stack out ^¬ practices. In contrast, the feeding unit 14 exerts a force directed in the tray ^¬ direction feeding force to the newly supplied notes of value and thus the value note stack, so that the platen unit 100 when feeding notes of value against the force applied by their backpressure force the further is moved in the storage direction PI, the more notes of value are received in the receiving area 16.

Thus, back pressure force is achieved by up by the counter-pressure unit 100 ^¬ brought that the banknotes of the banknote stack are always held together by a predetermined contact pressure and thus a slipping of the notes of value against each other and / or tilting of the security papers is avoided. This ensures that new banknotes can be fed safely via the feed unit 14.

In the figures 2 and 3 are each schematic, perspecti ^¬ vische representations of a section of the cashbox 10 shown in FIG. In this case, housing parts and also other elements of the cashbox 10 are not shown in order to better represent the storage of the counter-pressure unit 100 described below on the housing 12 of the cashbox 10.

The counter-pressure unit 100 is isolated in Figure 4 Darge ^¬ provides. The counter-pressure unit 100 includes a first tooth ^¬ wheel 102 and a second gear 104 meshing with each other. Further, on one of the side on which the first gear 102 and the second gear 104 are arranged, opposite side a third gear 106 and the third gear 106 meshing fourth gear 108 seen ^¬ before. The cash box 100 includes a first rack 20, a second rack 22, a third rack 24, and a fourth rack 26 that are parallel to each other. Here, the racks 20 to 26 are all directed in the storage ^¬ direction PI. The first gear 102 is engaged with the first rack 20, the second gear 104 with the two ^¬ ten rack 22, the third gear 106 with the third rack 24 and the fourth gear 108 with the fourth rack 26 in engagement. The second gear 104 and fourth gear 108 fixed for rotation on a common seed shaft ^¬ 110 (Figure 5) mounted so that all four toothed wheels ^¬ 102 to 108 engaged with each other and thus are always rotated evenly. Thus sicherge ^¬ provides that the counter-pressure unit is moved smoothly into the Abla ^¬ court tung PI and opposite to the offset direction PI and can not tilt. In particular, it is thus achieved that a contact stack unit 30 contacting the value stack always has the same orientation within the cash box 10, so that a secure abutment of the value stack on the contact unit 30 and thus also on the counter-pressure unit 100 is ensured. The Kon ^¬ clock unit 30 is in this case attached in particular via a plurality of compression springs on the counter-pressure unit 100 and is moved together with the counter-pressure unit 100 in the storage ^¬ direction PI and against the deposit direction PI.

The counterpressure unit 100 comprises a housing 112, which has a first housing part 114 and a second housing part 116. In FIG. 5, the first housing part 114 is hidden, in that with the internal components of the back pressure unit 100, which are protected by the housing 112, are more visible.

In the housing 112, a torsion spring 118 is arranged, which has a wound wire 120 having a first end 122 and a second end 124. Here, the torsion spring 118 is supported with its first end 122 on the housing 112, so that this first end 122 of the torsion spring 118 is rotatably mounted ^¬ fixed relative to the housing 112.

The first gear 102 is rotationally fixed on a shaft 130 ge ^¬ outsourced, so that the shaft 130 is rotated in accordance with a rotation of the Zahnra ^¬ of 104 accordingly. The second end 124 of the torsion spring 120 is also secured to the shaft 130 by being inserted into a hole 132 of the shaft 130. In Figure 6, this portion of the back pressure unit 100 is shown enlarged in detail.

Now, if a bill of exchange is fed by the feed unit 100 in the storage direction PI to the value already included in the receiving area 16 value stack, so this is pressed with a feed force against the feeder unit 14 ^¬ applied bill of exchange at the front of the WertScheinstapels. As a result, the force exerted on the counter-pressure unit 100 force is increased, so that it is also moved in the Ab ^¬ storage direction PI. The engagement of the first gear 102 in the first rack 20 and the engagement of the other gears 104 to 108 in the other rack 22 to 26 and the engagement of the gears 102 to 108 with each other, the first gear 102 is rotated in a first direction of rotation P2. Thus, the shaft 130 is rotated in the second rotational direction P2, so that the torsion spring 118 is twisted. By this torsion of the torsion spring 118, the required for the safe storage of notes of value in the receiving area 16 counter-pressure force is applied.

The more bank notes are taken already in the receiving area 16 on ^¬, the greater the weight force exerted by the stack of notes on the counter-pressure unit 100th Conversely, however, the torsion spring 118 is all the more twisted, the more notes of value are received in the receiving area 16, since the counter-pressure unit 100 is further moved in accordance with the deposit direction PI. Thus, the applied counter-pressure force is greater the more value ^¬ notes the recorded value ^note stack comprises. The characteristic curve of the torsion spring 118 is in particular such ge ^¬ selected, that the at ^¬ additionally applied by supplying new banknotes weight force is balanced by the correspondingly higher back pressure force due to the further twisting of the torsion spring 118 in approximately, so that the applied by the delivery unit 14 feeding force is inde ^¬ pendent on the number of previously recorded notes of value about the same.

Furthermore, the previously described embodiment with a torsion spring 118 has the advantage that the counter-pressure force is applied purely passive, ie that no drive unit for moving the counter-pressure unit 100 is necessary. The Moving the counter pressure unit 100 in the depositing direction PI takes place exclusively via the force applied by the feed unit 14, moving counter to the feed direction PI by the counterpressure force applied via the torsion spring 118, if notes of value are removed and thus the force acting on the counterpressure unit 100 is reduced.

Since the torsion spring 118 fully grew ^¬ taken in the housing 116, it is ensured that it does not come with other components of the cash box 100 or the notes of value in contact so that a particularly simple, platzspa ^¬ render and reliable construction is given.

In an alternative embodiment of the invention, more than one torsion spring 118 may be provided. In particular, two torsion springs may be provided 118, the 118 is connected with the first gear 102 and the walls ^¬ re torsion spring 118 with the third gear 106 is a torsion spring.

In Figure 7 a schematic, perspective illustration lung ^¬ a cashbox 10 according to a second embodiment ^¬ form is illustrated. Elements of the same design or moving ^¬ cher function have the same reference numbers.

The cash box 10 includes a housing 12 having a first opening 40 for machine feeding and / or removal of Bank notes and a second opening 42 for manual access. The second opening 42 is closed by a cover 44 in FIG. If the cover 44 is opened, notes of value can be manually fed and removed via the second opening 42 and / or a maintenance of the cash box 10 can be carried out.

FIG. 8 shows a top view of the cash box 10 according to FIG. 1, the cover 44 being hidden, so that the internal components are visible. FIG. 9 shows a sectional view through the cash box 10 according to FIGS. 7 and 8.

The cash box 10 according to the second embodiment has a receiving area 16 for receiving a value note stack, which is designed in such a way that the notes of value of the value note stack are received on their feet standing on the bottom of the cash box 10. The cashbox 10 to be supplied to the bank notes are fed via the first opening 40 by means of a stack and / or Vereinze ^¬ averaging module and moved to the offset direction PI within the view of the sixteenth In the receiving area 16, a counter-pressure unit 100 is provided, which is movable in storage ^¬ direction PI and against the deposit direction PI. The construction of the counter-pressure unit 100 will be explained in more detail below in connection with FIGS. 10 to 12. As well as the counter-pressure unit 100 and the Ge ^¬ back pressure unit 100 of the second embodiment is used in the first exporting ^¬ approximately example of Figures 1 to 6 to apply a counter to the offset direction PI directed back pressure force on the recorded value note stack to thereby prevent a drop of the notes of value. Thus, the note stack is always kept under a certain pressure, so that a reliable supply and removal of notes of value is possible. In FIGS. 8 and 9, the value-dept stack, which would actually be located between the opening 40 and the counter-pressure unit 100, is not shown in order to keep the other components of the cashbox 10 visible.

The more notes of value are supplied to the value note stack, the more the counterpressure unit 100 is moved counter to the counterforce applied by it in the depositing direction PI.

In the figures 10 and 11 a schematic, perspective view of the counter-pressure unit 100 of Figures 8 and 9 is shown in each case, wherein a Ge ^¬ housing 102 of the contrast unit is hidden, 100 in Figure 5, so that the internal components are visible. The counter-pressure unit 100 according to the second embodiment has a first shaft 134, which is coupled via two gears 136, 138 with a second shaft 140. At the two Endbe ^¬ ranges of the second shaft 140, two gears 102, 106 are arranged, which mesh with extending in the depositing direction PI on the sides of the cashbox 10 racks 20, 24. When the first shaft 134 is rotated in a direction of rotation P3, the second shaft 140 rotates via the coupling via the two gears 136, 138 against the direction of rotation P3 in a direction of rotation P4. The counter-pressure unit 100 via the engagement between the gears 102, 106 and the racks 20, 24 move in this case in the court Abla ^¬ tung PI.

Upon rotation of the first shaft 134 counter to the direction of rotation P3, ie upon rotation in the direction of rotation P4, the second shaft 140 rotates correspondingly in the direction of rotation ^¬ P3 and the counter pressure unit 100 moves within ^¬ within the receiving area 16 against the deposition direction PI ,

Further, the counter-pressure unit 100 comprises a spring unit 142, which analogous to the torsion spring 118 of the first embodiment of Figures 1 to 6 serves to bias the counter pressure unit 100 against the deposit direction PI and thus exert the necessary counterforce on the recorded value ^¬ apparent stack.

In Figure 12 a schematic perspective illustration ^¬ development of a section of the counter-pressure unit 100 is illustrated by Figures 10 and 11, wherein a housing 144 of the spring unit is hidden, 142, so as to make the interior of the spring unit 142 visible. The spring unit 142 comprises a drive spring 118, which is designed in the form of a spirally wound metal strip 146. A first end 148 of this metal band 146 is fixedly secured to the housing 144. The housing 144 in turn is non-rotatably attached to the housing 102 of the counter-pressure unit 100, so that the first end 148 is fixed relative to the housing of the counter-pressure unit 100 and rotationally fixed.

The first end 148 opposite second end 150 of the metal strip 146 is received in a groove 152 of the first shaft 134. If the first shaft 134, as is the case when moving the counter-pressure unit 100 in the deposition direction PI, rotated in the direction of rotation P3, the mainspring 118 is tensioned. The first shaft 134 rotates because ^¬ compared against the rotational direction P3, ie, in the direction of rotation P4, then the driving force relaxed 118th

Thus, the mainspring 118 is stretched the more, the more white ^¬ ter the platen unit is in the offset direction PI ^¬ be moved 100, so the more bank notes are received in the receiving area sixteenth Thus, the opposing force acting on the value ^¬ apparent stack increases so that it is securely held in the predetermined position and tipping notes of value is avoided. In contrast, if notes of value subtracted from the value note stack, the return ^¬ restoring force moves the mainspring 118, the counter-pressure unit automatic ^¬ table against the offset direction PI, so the recorded value note stack is obtained in each case below the required Min ^¬ least pressure. The use of a power spring 118 instead of a torsion spring 118 has the advantage that the design is more compact, since helically wound drive springs 118 requires much less space. In addition, such a mainspring can be very easily attached to the shaft 134 and the housing 144, so that the assembly is very easy.

In another embodiment, multiple drive springs 118 may be used for biasing.

It is also possible that individual features of the Geldkas ^¬ sette 10 according to the first embodiment of Figures 1 to 6, and characteristics of the cashbox 10 according to the second embodiment of Figures 7 to 12 are replaced with each other. In particular, the integrated Gegendruckein ^¬ 100 can be used according to the first embodiment in the cashbox 10 according to the second embodiment, and vice versa, the contrast unit 100 according to the second embodiment in the cashbox 10 according to the first embodiment.
