Description: Field of the Invention The present invention relates to a marking device in a paper money theft proof system. More particularly, the present invention relates to a marking device for providing a mark to paper money when the paper money in a paper money container, such as an automatic cash dispenser, a safe or an attache case, or the paper money container itself is stolen, for trace of the stolen paper money. Prior Art In recent years, along with the popularization of cash card and credit card, automatic cash dispensers (hereinafter it is simply referred to as the "CD machine" are placed all over the city, such as places in front of a station, supermarkets and department stores. The CD machine is so designed as not to permit a withdrawal in cash (paper money) contained in the interior of the CD machine without entering personal information such as a personal identification number and, besides, the CD machine is placed in specific room with a security camera(s), so that the paper money contained in the CD machine cannot be stolen with ease even when it is tried to be dishonestly taken from it. In addition to the security camera being in use during the period of time during which the CD machine is not in operation, the indoor or specific room for the CD machine to be placed is locked at the entrance. Besides, various security countermeasures are taken so that when someone tries to break the lock to break into the room without permission, an alarm such as an audible alarm or a silent alarm can be issued to a security company to inform it of the existence of the intruder and the extraordinary happening. However, many of the conventional security countermeasures are taken on the premise of the intruder entering the CD machine placing room or indoor from the entrance, so there is a possible fear that the security countermeasures may fail when the intruder breaks the wall or floor and breaks into the room therefrom. Also, even when the security countermeasures function adequately to issue the audible alarm to convey the alarm to security guards, if the intruder steals the CD machine in whole in a short time, there is the possibility that the paper money may already be stolen before the security guards rush in. On the other hand, the security countermeasures are also taken for cash transport using a cash transporting car by provision of e.g. radio transmitter that enables immediate radio contact with a police in case of an emergency of the cash transporting car. However, in this type of security countermeasures for the cash transport, if a robber(s) robs the paper money from the cash transporting car in a short time, as is the case with the CD machine, there is the possibility that the robber(s) may already run away before the police arrives at the scene. Thus, the conventional security countermeasures for the cash transport have the problem that no matter how the security is reinforced, once the paper moneys are robbed, it is hard to demonstrate whether the paper money used is the robbed one or not, so that the robber(s) can put the robbed paper moneys into circulation with no hassle. Thus, in the conventional security countermeasures, once the robber(s) succeeds in robbing, since it is hard to tell the difference between the robbed paper moneys and the circulating paper moneys, the robber(s) can use the robbed paper moneys at ease. In addition, since robber(s) tries to rob the paper money in a possible shortest time, there are increasing tendencies of arms such as a gun to be used in robbing the paper money, so that the crimes of violent and heinous nature are becoming conspicuous undesirably. To solve the problems mentioned above, a device has been sought that can be put into action so that when the paper money container itself or the paper moneys contained therein are tried to be taken out by force or violent, the trace and recovery of the robbed paper money can be ensured and facilitated to prevent the robbing of paper money. There has been proposed a marking device that can differentiate the paper money robbed or obtained by fraudulent acts, such as a destruction of the CD machine or an attack of a cash transport car, in such a manner as to let the public know that fact and also can trace the robbed paper money easily, to prevent the circulation of the robbed paper money and resultantly make the robber disincentive to rob paper money by violence. As disclosed by, for example, Japanese Patent Laid-open Publications No. Hei 6(1994)-108741 and Hei 7(1995)-9787, there has been proposed a marking device having means for spraying ink onto the paper moneys contained in a safe or the CD machine when they are tried to be forcibly taken out by fraudulent acts. However, this type of marking device having the means for spraying ink onto the paper moneys has the disadvantage that where the marking device is built in a precision machine, such as the CD machine, the ink sprayed exerts a bad influence on the CD machine. Specifically, the ink sprayed may cause troubles of the CD machine itself as well as mess the interior of the CD machine. The ink used for the marking device using the ink has the property of being hard to get out once it adheres to something, so that once the marking device is put into action to spray the ink, the whole CD machine using such a marking device must be replaced with the new one very expensively. In addition, even when the ink is sprayed on a cluster of paper money piled with density, it is hard to mark the entirety of the paper moneys with ink in an identifiable manner and it is probable that paper moneys in the middle of the pile of paper moneys may take ink at the sides thereof only. The paper moneys thus incompletely marked with the ink can be circulated with ease, so there is a possible fear that the marking of the paper moneys may be of meaningless. SUMMARY OF THE INVENTION Accordingly, the present invention has been made, aiming to provide a marking device in a paper money theft proof system that can surely provide a mark to paper money robbed or obtained by fraudulent acts, such as a destruction of the CD machine or an attack of a cash transport car, in such a manner as to let the public know that fact and also can be used repeatedly and thus economically. FR-A-2572907 discloses a marking device in a paper money theft proof system comprising a sensor that detects a shock produced when a paper money container is moved or broken to take out paper money contained in the paper money container; and a marking means for providing a mark to at least a part of the paper money under control of signals detected by the sensor, the marking means being so constructed as to cut the paper money partially. The present invention is characterized in that the marking means comprises a rotary cutting blade. The terminology of "paper money" used herein is intended to include, for example, merchandise coupons, exchange tickets, and negotiable securities, in addition to Bank of Japan Notes, Foreign Government Securities. Also, the terminology of "paper money container" used herein is intended to include a containing part of the CD machine for accommodating cashes, a solid box (lock box) for holding the paper money in trust, such as a safe, an attache case used for cash transport, and a cartridge built in these containers for casing cashes. The expression of "the paper money container is broken" used herein means that a lockage part of the paper money container is broken or a frame or a side wall of the paper money container is broken by cutting or a like manner. The expression of "the paper money container itself is moved" used herein refers to such a situation that where the paper money container is a cash containing part of the CD machine, the CD machine itself is carried out or taken away. No particular limitation is imposed on the sensor, as long as it is sensitive to a different shock from the shock generally given to the paper money container, like a mercury switch that is sensitive to vibration or tilt or a limit switch that is switched on when the paper money container is moved from its set position. In the marking device in the paper money theft proof system, the marking means comprises a cutting blade for partially cutting any side end of the paper money in the paper money container and shifting means for shifting one of the cutting blade and the paper money contained in the paper money container relative to the other in a direction for the paper money to be piled up. Also, the cutting edge of the cutting blade may take any forms including a saw-toothed edge form and a sharp-edged blade form, and no particular limitation is imposed on the form of the cutting edge of the cutting blade. Further, as long as the shifting means is constructed to allow one of the cutting blade and the paper money to move relative to the other in a direction of the paper moneys being piled up, it may allow the cutting blade to move relative to the paper money and vice versa, and no particular limitation is imposed thereon. The marking device may be provided with two or more cutting blades for cutting the paper money. In the construction noted above, the cutting blades may be placed in adjoining relation or may alternatively be placed so that they can confront different sides of the paper money, respectively. No particular limitation is imposed on the locations of the cutting blades. Also, the cutting blades may be so arranged that at least two different sides of the paper money at side end portions thereof can be cut by the cutting blades.

DETAILED DESCRIPTION OF THE EMBODIMENT With reference to the accompanying drawings, one preferred embodiment of a marking device in a paper money theft proof system in accordance with the present invention will be described below. It is to be understood, however, that the scope of the invention is by no means limited to the illustrated embodiments. Referring to FIG. 1, there is shown a perspective view showing one embodied form of a marking device in a paper money theft proof system in accordance with the present invention. As shown in FIG. 1, the marking device 1 in the paper money theft proof system (hereinafter it is simply referred to as the "marking device") is provided with a sensor 2, marking means 3 and a mounting plate 5 via which the marking device is mounted at a position adjacent to a paper money container 4 of the CD machine (not shown). The sensor 2 is located at a position in contact with a side wall 40 of the paper money container 4, as shown in FIG. 1, and has a mercury switch structure, as shown in FIG. 2. The sensor 2 comprises a mercury holding portion 20, mercury 21, a center electrode portion 22, a side electrode portion 23, a self-hold circuit 24 and a limit switch 25. The mercury holding portion 20 is formed by a dosed space having a depression 201 for holding the mercury 21 and a flat portion 202. The center electrode portion 22 is provided in a portion of the depression 201, and a ring-shaped mercury contacting element 230 connected with the side electrode portion 23 is provided in the flat portion 202. The sensor 2 is set in place with the mercury 21 held in the depression 201, as shown in FIG. 2. When the sensor 2 is tilted or shocked by, for example, vibration in excess of a predetermined vibration, the mercury 21 held in the depression 201 is moved out from the depression 201 and is brought into contact with the mercury contacting element 230 to close and make the self-hold circuit 24 through the side electrode portion 23 so as to transmit detecting signal S to the marking means 3. The sensor 2 is so designed that it can allow the transmission of detecting signal S to the marking means 3 to be stopped by pressing the limit switch 25 to open and break the self-hold circuit 24. The marking means 3 is provided with a rotary blade 31 serving as a cutting blade for cutting the paper money C, a rotation motor 32 for rotating the rotary blade 31, and shifting means 33 for shifting the rotary blade 31, as shown in FIG. 1. The shifting means 33 comprises a feed motor 330, a feed screw 331 and a feed nut 332. The rotary blade 31 has a saw-toothed cutting edge 310, confronting the paper moneys C contained in the paper many container 4, and is connected to the rotation motor 32 at a position over the paper money container 4, as shown in FIG. 1. The shifting means 33 is constructed to allow the feed screw 331 to be rotated by activation of the feed motor 330, so as to shift the feed nut 332 vertically in response to the rotation of the feed screw 331. The rotation motor 32 is connected with the feed nut 332 of the shifting means 33 so that the rotation motor 32 can be shifted vertically along a traveling rail 36 in response to the movement of the feed nut 332. The marking means 3 is put into action when it receives information from the sensor 2. When the marking means is activated, the rotary blade 31 is moved downward, while rotating, to cut part of the paper moneys, so as to provide the mark to the paper moneys C, as shown in FIG. 3. The paper money container 4 opens at a side thereof facing the rotary blade 31 to prevent the container from being cut by the rotary blade 31 moved downward. It should be noted that a battery is used as the power source of the marking device 1, though not shown, for preparation for a case of the feed of power source from external being stopped by a robber. In the following, operation of the marking device will be described. The marking device 1 is placed in the CD machine in such a manner that the rotary blade 31 is positioned above the paper money container 4 for containing the paper money C, as shown in FIG. 1. The sensor 2 in the marking means 3 of the marking device 1 is set with the mercury 21 in the mercury holding portion 20 held in the depression 201, as shown in FIG. 2. In other words, the sensor is set in the state in which no detecting signal S is transmitted by it. As long as the CD machine is used in a common manner, the marking device 1 thus set is not put into action and the CD machine using the marking device of the invention operates in no different manner from in the common CD machine. However, when the CD machine using the marking device 1 is shocked in an unordinary manner by tilt, vibration and the like caused by fraudulent acts, such as an act of the CD machine being lifted with a pry bar or other like tools to take away the CD machine in whole, the mercury 21 in the depression 201 of the sensor 2 built in the marking device 1 is moved out from the depression 201 and is brought into contact with the mercury contacting element 230. After the mercury 21 contacts with the mercury contacting element 230 for only a moment, the self-hold circuit 24 allows the detecting signal S to be transmitted to the marking means 3 through the side electrode portion 23 even after the mercury 21 returns to the original position in the depression 201. Since the detecting signal S serves as a power signal for actuating the marking means 3, when the detecting signal S is transmitted to the marking means 3, the marking means 3 is put in action. The marking means 3 uses the feed motor 330 and the rotation motor 32 as the power source. When the feed motor 330 is put into action, it drives the feed screw 331 to rotate, which in turn allows the feed nut 332 to move downward in response to the rotation of the feed screw 331. The rotation motor 32 allows the rotary blade 31 to rotate. Thus, the marking means 3 allows the rotating rotary blade 31 to move downward to cut the paper moneys C in the paper money container 4 partially with the rotating rotary blade, as shown in FIG. 1. The paper moneys C contained in the paper money container 4 are partially cut with the rotary blade 31 and thereby are each given a mark 300, as shown in FIG. 3. The mark 300 given to the paper money C draws one's attention very much when circulated and thus makes it very hard to circulate the marked paper money. Also, the paper money C thus marked is rebuffed by a money change machine, an automatic vending machine and the like, without being accepted by them. In addition, the marking pattern of the mark 300 allows the origin of the marked paper money to be envisaged with ease. It is needless to say that the marking means 3 may be made inactive in advance by means of the limit switch 25, for performing the normal activities such as, for example, additionally supplying the paper moneys C into the paper money container 4 or moving the CD machine building therein the marking device 1 to another place. Thus, even when the paper moneys C are robbed from the CD machine building therein the marking device 1 by fraudulent acts, since the paper moneys C are each given the mark 300, those marked paper moneys C can be easily traced back shortly after they are circulated by the robber(s) and besides cannot be accepted by the money change machine, the automatic vending machine and the like. As a result of this, the marked paper moneys C become totally useless. Also, as the marking device 1 becomes widespread and the existence of the marking device built in the CD machine comes to be known to the public, anyone will be disinclined to rob the paper money from the CD machine, and as such can contribute to prevention of crime. In addition, since the marking device 1 is designed to cut the paper money C partially with the rotary blade 31, when the marking device built in the CD machine or the like is put into action, it does not mess the interior of the CD machine so much, differently from the ink spraying type marking machine, and can be used repeatedly and besides can surely provide the mark to the paper money. Also, since the use of the rotary blade 31 is the most effective for cutting the paper money, there is no need to reinforce the floor and frame of the paper money container 4, as in the other marking ways such as the boring of paper money C. Further, since the paper money C marked by the marking device 1 can be recognized even in a dark place or by a person having bad eyesight or visual problems, the circulation of the marked paper money can surely be prevented. The marking device in the paper money theft proof system of the present invention is not limited to the above-illustrated form of the marking device 1. For example, while the marking device 1 is built in the CD machine in the illustrated embodiment, the marking device may be so modified as to be built in the other paper money container than the CD machine, such as an automatic vending machine, a safe or an attache case. Take a case of the marking device being built in an attache case, for instance. The marking device is then designed to include a sensor that shows reaction when the attache case is opened without using a regular key. The attache case thus designed can also allow the paper money to be marked. Accordingly, even when the paper moneys in this attache case are robbed by force on the way of the cash transport, the paper moneys can be marked to make the robber(s) disincentive to use those marked paper moneys. Accordingly, as the marking device used for the attache case or like cases becomes widespread, so that the existence of the marking device built in the attache case comes to be known to the public, anyone will be disinclined to assault a cash transporting car, and as such can contribute to prevention of crime. While the rotary blade 31 of the cutting blade is shifted from top to bottom by the feed screw 331 in the above-illustrated embodiment, it may alternatively be shifted from bottom to top. Also, the cutting blade may be formed into a straight saw-toothed cutting blade 61, as shown in FIG. 4. Two or more cutting blades may be used without limiting to a single cutting blade. More varieties of marking patterns can then be formed by the use of two or more cutting blades. The form or pattern of the marking 300 shown in FIG. 3 can be varied unlimitedly by varying the shape of the cutting edge 310 of the rotary blade 31. Accordingly, the origin of the marked paper money C can be envisaged from the information on the marking pattern in the same principle as, for example, the principle in which a boarding station is envisaged from the information on the punching pattern of a ticket punch. Further, the marking device of the invention may be so modified as to cut the paper money C at two or more sides thereof, rather than at one side thereof as in the above-illustrated embodiment. This modification can provide the result that even when a robber(s) tries to use the paper money C by deception by tearing portions of the paper money C around the marks provided by the cutting, he/she/they cannot, because the paper money C will then have to be torn unnaturally at several parts thereof. While the shifting means 33 is designed to shift the rotary blade 31 by the feed screw 331 and the feed nut 332 in the above-illustrated embodiment, the shifting means may be so modified as to shift the rotary blade 331 in such a manner that the paper money C can be cut by only the turning force of the rotary blade 331, without using the feed screw. Also, the shifting means may be so modified as to shift the cutting edge horizontally, depending on the orientation for the paper moneys C to be contained. In addition, a modification may be made in the marking device of the invention by making the rotary blade 31 stationary, while making the paper money container 4 move vertically. Also, while the sensor 2 is in the form of the mercury switch in the above-illustrated embodiment, the commonly used sensor, such as a limit switch or a proximity switch, may be used instead of the mercury switch. ADVANTAGE OF THE INVENTION The marking device in a paper money theft proof system thus constructed can surely differentiate the paper money robbed and obtained by fraudulent acts, such as a destruction of the CD machine or an attack of a cash transport car, in such a manner as to let the public know that fact. Also, the marking device of the invention using no ink can allow the interior of the CD machine to be kept from pollution even when used repeatedly, so that the repeated use and the economical use can be attained. Thus, even when the paper money are robbed by fraudulent acts, the robber(s) are made disincentive to circulate those robbed paper money and resultantly made disincentive to rob paper money by violence by fraudulent acts. Also, the marking device in a paper money theft proof system according to the invention can surely provide the mark to all of paper moneys even when piled up high. Further, the marking device in a paper money theft proof system according to the invention can provide more marking patterns, so that the origin of the marked paper money can be envisaged with ease from the marking pattern. In addition, the marking device in a paper money theft proof system according to the invention can provide the marks to two or more sides of the paper money, so that a robber(s) can be made disincentive to cheat such as, for example, tearing marked portions of the paper money.
