Description: METHOD AND DEVICE FOR MARKING OF OBJECTS The present invention relates to an object marking method as defined in the preamble of Claim 1. The invention also relates to a device for carrying out the method and to the use of such a device. In connection with so-called dispensing machines, such as cash dispensers, automatic telling machines, and the like, there is a need for equipment that will stain banknotes if an attempt is made to steal the contents of the machine. These attempts may be made, e.g., by blowing open the cash dispenser, breaking open the dispenser or by cutting open the dispenser with the aid of a gas cutting appliance. One object of the present invention is to provide a method and a device which, when necessary, will mark objects stored in banknote cassettes or other types of valuable object storages in a particularly effective manner. This object is achieved with the method and the device that have the characteristic features set forth in the following claims . The following advantages are among those afforded by the present invention. The inventive method and inventive device cause the liquid container to be punctured or otherwise opened, so that the liquid content of the container will come into contact with the object/objects and therewith mark the object/objects and/or render said object/objects unusable in a particularly effective manner. For instance, a slot is made along the full length of the container that contains the destructive agent, so that said agent is able to run out gravitationally over the bundle of banknotes for instance . The inventive device can be given any desired size and is adapted to desired requirement specifications . The inventive device can be readily adapted to suit existing pay machines, automatic telling machines, banknote dispensing machines, and like machines. The inventive method and inventive device can also be used in other equipments when, for instance, drop-staining or spray-staining is desirable. The inventive device has both technical and economical advantages . The invention will now be described in more detail with reference to exemplifying embodiments thereof and also with reference to the accompanying drawings, in which Figure 1 is a cross-sectional, schematic view of the inventive device fitted in a banknote cassette; Figure 2 is a sectional and schematic longitudinal view of the inventive device fitted in a banknote cassette; Figure 3 is a schematic view of the inventive device from beneath; Figure 4 is a broken, schematic longitudinal view of the inventive device; Figure 5 is a schematic end view of the device taken on the line V-V in Figure 3; Figure 6 is a schematic sectioned view taken on the line VI-VI in Figure 3 ; Figures 7 and 8 are respective schematic sectioned views taken on the line VII-VII in Figure 3, wherewith Figure 7 shows the device in a safe or unarmed state and Figure 8 shows the device in an armed state. Figures 1 and 2 illustrate the inventive device 10 fitted to a so-called banknote cassette 1 filled with a bundle of banknotes 100. The illustrated cassette 1 comprises a box-shaped bottom part 2 and a cover 3. The underside of the cover, or lid, 3 includes guide bars 4 which ensure correct orientation and alignment of the banknotes in the cassette 1. Although not shown, the cassette 1 normally includes a spring-biased banknote dispenser arrangement. Such banknote cassettes 1 are filled with banknotes and used, e.g., in cash dispensers, automatic telling machines, pay machines and like machines. The inventive device 10 is designed to be fitted beneath the cover 3 of a banknote cassette 1. The marking mechanism of the device 10 is armed in conjunction with fitting said device into the cassette. The marking device 10 includes a casing 11, which is preferably an extruded structure and which includes a longitudinally extending slot 12 in the bottom thereof, as will be best seen from Figures 3-8. The marking device 10 also includes a carriage-mounted cutting device 13 which is adapted to slide along the slot or slit 12 whilst guided by two guides 14. The cutter 13 has a rearwardly sloping cutting edge 15 on its front end. The cutter 13 also includes a hole 16 whose function will be described more explicitly below. A wire or cord 20 is secured to the cutter/opening device 13 at an attachment point 21 and the cord 20 runs from said anchoring point 21 along said slot 12. The wire or cord 20 is deflected around two bushings 22 and 23 provided in a removable end wall 17, and thereafter deflected at a deflecting ring 24 and then anchored relative to the profiled casing 11 in the proximity of the end wall 17. The pattern in which the wire or cord is drawn through the device will best be seen from Figure 3 , from which it will also be seen that the wire deflecting ring 24 is connected to a first end 25 of a pull spring 26 whose other end 27 is anchored relative to the casing 11 at the rear end 18 of the casing. The object marking device 10 also includes a release mechanism/locking mechanism 30 which is adapted to hold the puncturing device/opening device/cutter 13 in an inactive starting position and which functions to release the cutting device when an alarm is triggered. The locking mechanism/release mechanism 30 includes a pivotal release rocker 32. The release rocker 32 is pivotally mounted on a pivot point 33 and includes a knife holder pin 34 which is insertable into the hole 16 of the knife means 13 , as shown in Figure 4. The release rocker 32 also includes a balance weight 36 which determines the release level or the release sensitivity of the release mechanism. The configuration of the pivot pin and its angle of inclination can be adapted so as to obtain the release sensitivity desired. As evident from the Figures, the pull spring 26 is disposed on the outside of the casing 11. The device 10 also includes a safety mechanism 40 for avoiding unintentional activation of the object marking device 10 in conjunction with moving or transporting said device at a distance from its place of use, in other words when the marking device 10 is not placed in a banknote cassette 1 for instance. The safety mechanism 40 includes a safety rocker 42 which is pivotally mounted on a pivot point 41 and which includes a tongue 43 which in its safety position lies behind the release rocker 32 and therewith prevents the rocker from pivoting to a release position, in other words from releasing its engagement with the cutter 13. This safety position is shown in Figure 7. Figure 8, on the other hand, shows the safety mechanism 40 in a non-safe or armed state, in which an arming pin 6 provided in the cassette 1 has moved the safety rocker 42 to the position shown in Figure 8, in which the tongue 43 has left its position behind the release rocker 32 so that it can now pivot to enable the pin 34 to release its engagement with the cutter 13. If desired, a permanent magnet 46 or a spring may be fitted so as to ensure, with a desired force, that the safety rocker 42 will not be moved from its safety position unintentionally or accidentally before the arming pin 6 has armed the marking device 10 as it is placed finally in its position of use in the cassette 1. A protective plate 50 is mounted within the casing 11 so as to prevent a container 60 placed in the casing from coming into abutment with the knife edge 15 when the cutter 13 is located in its starting position, as shown in Figure 4. As will be seen from Figure 6, the protective plate 50 has a recess 51 which enables the cutter 13 to pass by the protective plate 50 when an alarm is triggered. The container 60 may, for instance, have the form of a plastic foil casing, which is filled with a destructive agent 61. The destructive agent 61 may comprise a liquid or a stain comprised of strong colors, so that desired staining/destruction of the banknotes 100 in the cassette 1 can be accomplished when required or necessary. The container 60 may thus consist of a plastic foil hose which is sealed at both ends and filled with a liquid that is appropriate in the present context. The inventive object marking device 10 operates in the following way. The marking device 10 is charged with a liquid-filled container 60, by removing temporarily the detachable end wall 17 for instance. In this stage, the cutter 13 is located in its rear inactive position and the release mechanism 30 is in firm locking engagement with the cutter. The end wall 17 is then replaced in its normal position and the pull spring 26 is placed under tension. The release mechanism 30 is made safe by means of the safety mechanism 40. The marking device 10 duly charged with a liquid container 60 and armed in the aforedescribed manner is now fitted beneath the cover 3 of a banknote-filled cassette 1, with the arming pin 6 of the cassette functioning to arm the marking device 10 when it is located within said cassette. The cassette 1 is then placed in a pay machine, automatic telling machine, automatic cash dispenser or the like. The device will operate in the following manner in the event of an unlawful attack on the machine. If an attempt is made to enter the machine with the aid of an explosive for instance, the release mechanism 30 will be actuated so as to cause the knife holder pin 34 to move out of engagement with the cutter 13 and therewith release the cutter for movement along the slot 12 under the action of the pull spring 26, in the direction of the arrow A. The knife edge 15 will therewith work forwards through the container 60, in the manner of a guillotine, so as to form an elongated slit in said container through which the liquid content of said container are able to run over the banknotes under the force of gravity, and therewith stain the banknotes 100 and render them useless by virtue of being stained or marked. The container 60 is thus emptied of its stain content/liquid content relatively quickly and very effectively. In the case described, the marking device 10 is triggered by vibrations occurring as a result of the explosion, therewith destroying the banknotes . However, alternative release mechanisms that react to attempts to force open such machines with which no such vibrations occur are possible within the scope of the invention. One example in this regard is a release mechanism that includes a wire system 70 which is adapted to actuate the release mechanism 30 in response to a rise in temperature for instance, caused by attacking the machine with a cutting torch or in some other way. Such a wire system 70 is indicated in chain lines in Figure 4. It can be mentioned that the pulling force of the spring 26 is at a maximum when the container 60 is punctured initially, which is, of course, highly beneficial. The arrangement of the line 20 and the spring arrangement may, of course, be varied within the scope of the invention. The transmission achieved with the illustrated line path is sufficient to ensure that the cutter will execute an effective working stroke . The spring is normally stretched or extended manually. A roller or plunger 80 functioning to forcibly empty the container 60 of its liquid content may be provided adjacent the container 60 or within said container 60 at its rear end, said plunger 80 being moved forward under the influence of the cutter 13 as the knife slide is pulled in the direction of arrow A when an alarm is triggered. It should be mentioned that the container 60 may have a relatively stable construction, provided that it has a weakening which will enable the cutter 13 to puncture the container 60 in a guillotine fashion in the region of forward movement of the knife edge 15. A more stable container construction will, of course, simplify fitting of the container into the marking device 10. It will be understood that the structural design of the inventive device 10 can be modified and varied in several ways. For instance, the described and illustrated components can be replaced with functionally equivalent components . Changes in cutter design and in the design of the knife slide may also be made, as may also changes to the way in which the line, e.g. the wire or cord, is drawn and the spring arrangement. The release mechanism and the safety mechanism may, of course, also be varied in many different ways other than that illustrated. It will be noted that the inventive device in its fundamental form is completely free of electronic devices and is based on mutual coaction between mechanical components . The invention is thus not restricted to the illustrated and described embodiments thereof, since changes and modifications can be made within the scope of the following claims.
