不正検出装置１７は、図３に示すようにＣＰＵ１８・ＲＡＭ１９・ＲＯＭ２０・インターフェイス２１・警報部２２・スピーカー２３・警報ランプ２４・信号線２５で構成し、ビルバリ４・下限センサー１１・補給停止センサー１２・満量センサー１３は信号線２５を介して接続している。ＲＯＭ２０内のプログラムは、補給装置７で自動補給する場合は、下限センサー１１が検知した時点からその直前のバッチ補給完了時点との間における投入金額ａ（ビルバリ４へ投入する度に識別される各識別金額ｂの合計）を売上相当金額ｃから差し引いた差額が２０００円以上であった場合に補給装置７と払出器１０の作動を停止させ、警報音をスピーカー２３で発音させるとともに警報ランプ２４を点灯させるように構成し、人手で補給する場合は、補給停止センサー１２が検知した時点からその直前のバッチ補給完了時点との間における投入金額ａ（ビルバリ４へ投入する度に識別される各識別金額ｂの合計）を売上相当金額ｃから差し引いた差額が２０００円以上であった場合に補給装置７と払出器１０の作動を停止させ、警報音をスピーカー２３で発音させるとともに警報ランプ２４を点灯させるように構成している。不正検出装置１７はビルバリ４の上部に内蔵させ、スピーカー２３と警報ランプ２４を不正検出装置１７の正面に備え、筐体２の正面にスピーカー２３用のスリットと警報ランプ２４用の窓を形成している。 As shown in FIG. 3, the fraud detection device 17 includes a CPU 18, a RAM 19, a ROM 20, an interface 21, an alarm unit 22, a speaker 23, an alarm lamp 24, and a signal line 25, and a bill validator 4, a lower limit sensor 11, and a supply stop sensor 12. The full sensor 13 is connected via a signal line 25. When the replenishing device 7 automatically replenishes the program in the ROM 20, the amount of money a (between the time point when the lower limit sensor 11 detects and the time when the batch replenishment immediately before that is completed is identified each time the bill validator 4 is charged. When the difference obtained by subtracting the sum of the identification amount b) from the sales equivalent amount c is 2000 yen or more, the operation of the replenishing device 7 and the dispenser 10 is stopped, the alarm sound is generated by the speaker 23 and the alarm lamp 24 is turned on. When the replenishment is performed manually, when the replenishment stop sensor 12 detects it, the amount of money a (between the time when the batch replenishment is completed immediately before the replenishment of the batch replenishment a) When the difference obtained by subtracting the sum of the amount b) from the sales equivalent amount c is 2000 yen or more, the operation of the replenishing device 7 and the dispenser 10 is stopped, and an alarm sound is generated. It is configured so as to light the alarm lamp 24 together to sound the speaker 23. The fraud detection device 17 is built in the upper part of the building burr 4, and the speaker 23 and the alarm lamp 24 are provided in front of the fraud detection device 17, and a slit for the speaker 23 and a window for the alarm lamp 24 are formed on the front of the housing 2. ing.

本実施例では、貨幣投入口３に貨幣が投入されると、その投入金額に応じた枚数のメダルｍがメダルホッパー９から払出器１０で計数しながら払い出され、払い出しで減少したメダルｍが下限センサー１１で検知されると、補給装置７が作動して供給ライン６のメダルｍが補給路８を通じてメダルホッパー９へ取り込まれ、補給されたメダルｍが積み上がって補給停止センサー１２で検知されると補給装置７が停止する。 In this embodiment, when money is inserted into the money insertion slot 3, the number of medals m corresponding to the amount inserted is paid out while counting with the dispenser 10 from the medal hopper 9, and the medals m reduced by the payout are obtained. When detected by the lower limit sensor 11, the replenishing device 7 is activated and the medal m of the supply line 6 is taken into the medal hopper 9 through the replenishment path 8, and the replenished medal m is stacked and detected by the replenishment stop sensor 12. Then, the replenishing device 7 stops.

不正検出装置１７では、図５（ａ）に示すようにバッチ補給が完了した（補給停止センサー１２が検知した）時点からビルバリ４の識別金額ｂを投入の度に積算して投入金額ａを求めていき、下限センサー１１が検知した際に、前記求めた投入金額ａ（識別金額ｂ₁＋ｂ_n・・・の合計）を予め設定したバッチ補給１回分の売上相当金額ｃから差し引いた差額が２０００円を含むそれ未満の場合は投入金額ａに応じた枚数のメダルｍが払い出されたと判断して監視を継続する。 In the fraud detection device 17, as shown in FIG. 5 (a), from the time when the batch replenishment is completed (detected by the replenishment stop sensor 12), the identification amount b of the bill burr 4 is integrated every time the amount is inserted to obtain the amount a. When the lower limit sensor 11 detects, the difference obtained by subtracting the calculated input amount a (the total of the identification amount b ₁ + b _n ...) From the sales equivalent amount c for one batch supply set in advance is 2000. If it is less than that including the yen, it is determined that the number of medals m corresponding to the inserted amount a has been paid out, and monitoring is continued.

図５（ｂ）に示すように、バッチ補給完了後に何者かが例えば１０００円を投入し、巡回する店員や警備員の隙を突いて、払出器１０の計数手段（図示せず）を様々な手口で狂わせてメダルｍを不正に抜き取ろうとする。計数手段を狂わされた払出器１０はメダルｍをさらに払い出し続け、下限センサー１１が検知する。不正検出装置１７は投入金額ａを売上相当金額ｃから差し引き、この場合の投入金額ａは最初に投入された識別金額ｂ₁の１０００円のみで差額が３０００円となるから、不正検出装置１７は作動中の補給装置７と払出器１０を即時に停止させてスピーカー２３で警報音を発音するとともに警報ランプ２４を点灯させ、その警報音や点灯で店員や警備員が駆けつけて不正行為が防止される。 As shown in FIG. 5 (b), after the completion of the batch replenishment, a person throws in, for example, 1000 yen, and the counting means (not shown) of the dispenser 10 is changed in various ways by catching the space between the clerk and the security guard. It tries to get medals m out of order by madness. The dispenser 10 whose counting means has been distorted continues to pay out the medal m, and the lower limit sensor 11 detects it. The fraud detection device 17 subtracts the input amount a from the sales equivalent amount c. In this case, the input amount a is only 1000 yen of the identification amount b ₁ initially input, and the difference is 3000 yen. The replenishing device 7 and the dispenser 10 that are in operation are immediately stopped, an alarm sound is generated by the speaker 23 and an alarm lamp 24 is lit, and the clerk and guards rush to the alarm sound and lighting to prevent fraud. The

メダルｍの補給を人手で行う場合は、貨幣投入口３に貨幣が投入されると、その投入金額に応じた枚数のメダルｍがメダルホッパー９から払出器１０で計数しながら払い出され、払い出しで減少したメダルｍが補給停止センサー１２で検知されると補給指示装置１４の補給開始ランプが点灯し、作業者はメダルｍをメダルホッパー９へ直接又は補給路８を通じて補給し、補給されたメダルｍが積み上がって満量センサー１３で検知されると補給指示装置１４の補給停止ランプが点灯して作業者は補給を終了する。 When the medal m is replenished manually, when money is inserted into the money insertion slot 3, the number of medals m corresponding to the amount inserted is paid out while being counted by the dispenser 10 from the medal hopper 9. When the replenishment stop sensor 12 detects the reduced medal m, the replenishment start lamp of the replenishment instructing device 14 is turned on, and the operator replenishes the medal m directly to the medal hopper 9 or through the replenishment path 8 and replenished medal. When m accumulates and is detected by the full sensor 13, the replenishment stop lamp of the replenishment instructing device 14 is turned on and the worker ends replenishment.

不正検出装置１７は、図６（ａ）に示すようにバッチ補給が完了した（満量センサー１３が検知した）時点からビルバリ４の識別金額ｂを投入の度に積算して投入金額ａを求めていき、補給停止センサー１２が検知した際に、前記求めた投入金額ａ（識別金額ｂ₁＋ｂ_n・・・の合計）をバッチ補給１回分の売上相当金額ｃから差し引いた差額が２０００円を含むそれ未満の場合は投入金額ａに応じた枚数のメダルｍが払い出されたと判断して監視を継続し、図６（ｂ）に示すように投入金額ａを売上相当金額ｃから差し引いた差額が２０００円以上であった場合は作動中の補給装置７と払出器１０を即時に停止させてスピーカー２３で警報音を発音するとともに警報ランプ２４を点灯させる。 As shown in FIG. 6A, the fraud detection device 17 obtains the input amount a by adding the identification amount b of the bill burr 4 every time it is input from the time when the batch replenishment is completed (detected by the full sensor 13). When the supply stop sensor 12 detects, the difference obtained by subtracting the calculated input amount a (the sum of the identification amount b ₁ + b _n ...) From the sales equivalent amount c for one batch supply is 2000 yen. If it is less than that, it is determined that the number of medals m corresponding to the input amount a has been paid out, and monitoring is continued, and the difference obtained by subtracting the input amount a from the sales equivalent amount c as shown in FIG. Is 2000 yen or more, the replenishing device 7 and the dispenser 10 in operation are immediately stopped, an alarm sound is generated by the speaker 23, and the alarm lamp 24 is turned on.

図７に示すのは、補給路の途中位置にメダルの通過枚数を計数する計数器を設け、下限センサーが検知すると計数器の計数枚数が所定枚数に達するまで補給装置を作動させて一定量のメダルを自動的に補給するようにした実施例の他の例である。図７は実施例の他の例のメダル貸し機の説明図である。図中、８ａは計数器で、制御部５と接続している。 FIG. 7 shows that a counter for counting the number of passing medals is provided in the middle of the replenishment path, and when the lower limit sensor detects, the replenishing device is operated until a predetermined number of counters reach the predetermined number, and a fixed amount is obtained. This is another example of the embodiment in which medals are automatically supplied. FIG. 7 is an explanatory view of a medal lending machine of another example of the embodiment. In the figure, reference numeral 8a denotes a counter which is connected to the control unit 5.
