Abstract

PROBLEM TO BE SOLVED: To effectively enable preventing of burglary of a very small product by actuating an alarm when the sum of weights of a product display plate and products placed thereon is reduced from a previously measured total weight value and when it is not yet returned to the total weight value within a specified time.
SOLUTION: Individual weight sensors 3a are installed on display plates 2 of a commercial display case 10 in which the proper number of display plates 2 are mounted to allow measuring of the weights of the display plates 2 and of a product P on display to be placed thereon 2 and a measured value thereof is always automatically inputted into a computer 4. The computer 4 is made to store the measured value and judges and detects whether the weight values sequentially inputted are reduced or not in comparison with the total weight value stored. If the sum of the weight values reduced is not restored to the total weight value within a specified time previously inputted and set, an alarm 6 is actuated. This information is transmitted to a receiver 8 such as pager or cellular phone by an wireless device 7.

【0020】図1は、本発明方法のシステム例を示すもので、該図に於て10はショーケースで、それぞれその内部に陳列板2が適宜枚数棚状に架設されている。 [0020] Figure 1 shows an example system of the present invention method, Te 10 at the figure in the showcase, display plate 2 therein respectively are bridged appropriate number ledge. このショーケース10には、例えば対向する側壁板1a、1 The showcase 10, for example, opposing side wall panels 1a, 1
bに設けられた陳列板受止用の内方突出部11を利用し、その上面にそれぞれ重量センサ3aが設置され、陳列板2及び陳列物品Pの重量が測定されるようになっていると共に、その測定値はコンピュータ4に常時自動入力されるようになっている。 Utilizing inward protrusion 11 for display plate catch provided on b, the weight sensor 3a respectively disposed on the upper surface thereof, with the weight of the display plate 2 and display article P is adapted to be measured , the measured value is made to be constantly automatically input into the computer 4. 尚、この入力は適宜インターフェース5を介する有線接続でも無線によるものでも良い。 Incidentally, this input may be by wireless and a wired connection through the appropriate interface 5. 而して、該コンピュータ4は、重量センサ3aで予め測定の上、入力設定された陳列板2とその上に載置されるべき全物品Pの総重量値を記憶する手段と、重量センサ3aによって得られる陳列板2及びその上に現実に載置されている物品Pの合計重量値の前記自動入力データが、前記記憶された総重量値に比して減少しているか否かを判定検知する手段と、予め入力設定した所定時間内に、減少した合計重量値が前記総重量値に復帰しない場合に警報装置6が作動するように、換言すれば所定時間内に復帰すれば警報装置6は作動しないように制御する手段とを備えるものである。 And Thus, the computer 4, the weight on the previously measured by the sensor 3a, the input set display plate 2 and the means for storing the total weight values ​​of all the articles P to be placed thereon, a weight sensor 3a the automatic input data of the combined weight values ​​of the display plate 2 and the article P which on being placed in the reality that is obtained by the determination detects whether decreased in comparison with the total weight value that is the storage means for, within a predetermined time entered preset as reduced total weight value is said alarm 6 if not return to a total weight value is activated, the alarm device if the return within a predetermined time in other words 6 it is intended and means for controlling so as not operate. ここに警報装置6としては、音響(ブザー等)あるいは光(ランプ等)によるもの等その具体的手段の如何を問わず、また、この情報は無線装置7によりポケベルや携帯電話等の受信機8に通報せしめるようにしても良い。 The alarm device 6 here, regardless of their specific means such as by an acoustic (buzzer) or light (lamp), also this information, such as pagers and cellular phones by radio device 7 receiver 8 it may be allowed to report to.

【0021】20は内部の陳列板2の上面に接触センサ3bを設置したショーケースで、陳列板2上に載置された物品Pの陳列板2からの離脱を該接触センサ3bにより検知すると共に、該接触センサ3bの出力データはコンピュータ4に入力され、前記の重量センサ3aの場合と同様予め該コンピュータ4に入力設定した所定時間内に陳列板2と物品Pの接触状態が復帰しない場合に警報装置6が作動するようにコンピュータ制御されているものである。 [0021] 20 is a showcase installed contact sensor 3b to the upper surface of the display plate 2 inside, the departure from the display plate 2 placed on the display plate 2 article P together is detected by the contact sensor 3b , the output data of the contact sensor 3b is inputted into the computer 4, when the contact state of the display plate 2 and the article P does not return within a predetermined entered set when the same advance the computer 4 of the weight sensors 3a time alarm device 6 is one that is computer controlled to operate.

【0022】30は自宅や事務所に保管される金庫、また40は携行されるアタッシュケースで、内部の物品陳列(載置)板に重量センサ3aや接触センサ3bを取り付け、当該センサの出力データを無線装置7によりコンピュータ4に入力し、前記と同様警報装置6の作動がコンピュータ制御されているものである。 [0022] 30 is attache safe stored in the home or office, also 40 to be carried, mounted on the weight sensor 3a or contact sensor 3b in the interior of the article display (placed) plate, the output data of the sensor input to the computer 4 by the radio device 7, the operation of the same alarm device 6 is one that is computer controlled.

【0023】尚、本発明方法に於ては、重量が減少した時点あるいは物品の陳列板からの離脱が検知された時点で、第一次的に予告警報(ランプ等)を作動せしめても良い。 [0023] Incidentally, Te is at the present invention method, when the withdrawal from the display plate at the time, or article weight is reduced is detected, it may be actuated primary to notice warning the (lamp) .

【0024】また、コンピュータ4の電源ラインにカードロックを設け、システムの入り/切りは、例えばボックスコードを利用したカードキーにより行なえば、カードキーを使用せずに電源が落ちた場合には、警報システムを不正に解除したものと考えられるので、電源を予備電源に切り替え、警報を作動せしめるようにすれば、本発明システムの安全性がより担保される。 [0024] In addition, the card lock provided on the power line of the computer 4, On / Off of the system is, for example, be carried out by the card key using the box code, in case power is lost without the use of a card key, it is considered that those released illegally alarm system, switching the power to the backup power source, if so allowed to activate an alarm, the safety of the inventive system is more secured.

【0025】 [0025]

【発明の効果】本発明によれば、物品が陳列板に載置されているか否か、すなわち物品を陳列板から取り外したか否かを重量センサや接触センサにより的確に検知し得るので、宝飾品の如く極く小型の商品でもその盗難を効果的に防止することができる。 According to the present invention, whether the article is placed on the display board, that is, capable of precisely detected by whether a weight sensor or a contact sensor is removed an article from the display plate, jewelery even in a very small size of the product as it is possible to prevent the theft effectively. しかも、陳列板から物品を一旦取り外しても所定時間内であれば警報装置は作動することがないので、例えば購入しようとする者が手に取って商品を吟味することに何ら支障は生じない。 Moreover, since there is no possible to operate the alarm system, if even temporarily remove the goods within a predetermined time from the display plate, for example, a person who intends to purchase does not occur any trouble to examine the goods taken in hand.
