この発明は、一般家庭、および事業所などの、特に外界
との境界としての扉に設置する錠に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lock installed on a door of a home, a business office, etc., particularly as a boundary with the outside world.

きなトルクとストロークが得られないことと、錠の溝造
上錠本体は扉部分に設置しなければならぬ事が、堅牢性
と確実性に限界を来すという欠点もあった。In conventional locks, the lock and key are made more complex to prevent the lock from being opened using a simple gong. Locks and keys need to be updated. In particular, in recent years, keys have been easily duplicated in cloth, and this has led to the use of keys in rental offices, apartments, and residential buildings where users or residents change relatively frequently. There is a drawback that sufficient security cannot be guaranteed unless the lock and key are renewed each time the person or resident changes, and this cost is also a drawback that cannot be ignored. Furthermore, with conventional keys, due to the 11-key structure, large torque and stroke cannot be obtained, and the lock's grooved top lock body must be installed on the door, which reduces its robustness. There was also the drawback that there was a limit to certainty.
本発明は上述の欠点を解決する事５：目的とするもので

単な再調整によって、安全保証は容易に達成する事がで
きる様にしたものである。The present invention aims to solve the above-mentioned disadvantage (5).Even if the key is lost or stolen, or the user or resident of the room or residence changes, there is no need to renew the lock body, and the key can be locked. Safety guarantees can be easily achieved by replacing the permanent magnet attached to the shore, or by increasing or demagnetizing it to a different magnetic flux density, and by simply readjusting the electrical circuit of the sensing device. I made it possible.

ことが出来るなどの利点も提供する。Furthermore, due to the structure and shape of conventional locks and keys, we installed only an escape hole, a sensing device, and an insertion hole in the door, instead of the general concept of installing the lock body inside the door. It is also possible to arrange the main body and other required equipment to be installed on opposing pillars or in a distributed arrangement within the wall.Furthermore, it is also possible to install only an insertion hole in the door, and to cut out the escape hole and other required equipment. , installed on opposite pillars or within a wall. By adopting an arrangement that is completely opposite to the conventional concept, the robustness and reliability of the lock can be increased, the structure of the door can be simplified and its cost can be reduced, or the lock can be tightened with ease. It also offers advantages such as being able to renew the door.
以下図面に従って本発明の詳細な説明する。The present invention will be described in detail below with reference to the drawings.
第１図は本発明が準拠する基本的原理であるところの、
磁気抵抗素子への磁界印加による、該素子の電気抵抗値
変化の１σ１ｊを示す。拐軸は該素子に印加する磁束密

束密度の際、磁気抵抗素子の電気抵抗値は、磁界が印加
されない時の値の約３倍の値に迄増加する事が判る。FIG. 1 shows the basic principle to which the present invention is based.
It shows 1σ1j of the change in electrical resistance value of a magnetoresistive element due to the application of a magnetic field to the element. The horizontal axis is the magnetic flux density applied to the element, and the vertical axis is the magnification of the change in electrical resistance of the element corresponding to that value. It can be seen from this curve that, for example, at a magnetic flux density of 3 kilogauss, the electrical resistance value of the magnetoresistive element increases to a value about three times the value when no magnetic field is applied.
この磁界印加の際の電気抵抗値の増加を、電気的信号と
して取り出す方法は多数あるが、此処ではその１例とし
て、第２図に示す、普遍的なブリッヂ型回路について説
明する。勿論、本発明の適用はブリッジ回路にのみ限定
するもので無いのは当然で、説明の簡単のために、此の
後もブリッジ回路を例として説明する。第２図において

るための平衡条件は、Ｚ１Ｚ４＝Ｚ２Ｚ３であることは
広（公知されて居る。There are many methods for extracting this increase in electrical resistance value upon application of a magnetic field as an electrical signal, and here, as an example, a universal bridge type circuit shown in FIG. 2 will be explained. Of course, the application of the present invention is not limited to bridge circuits only, and for the sake of simplicity, the bridge circuit will be described as an example from here on as well. In Fig. 2, Z-work, Z2, Z3, and VZ4 each indicate the load, and 1
indicates an output circuit, and 2 indicates a power supply. It is widely known that the equilibrium condition for the current in the output circuit to become zero is Z1Z4=Z2Z3.

際、可変抵抗器３は、複数個の組合せである事も本発明
に含まれることは当然である。In the present invention, when the permanent magnet 5 attached to the key comes into contact with the magnetic resistance element 4, it is easy to adjust the variable resistor 3 to 1, 1, which satisfies the above condition ZIZ4=Z2Z3. be. In the state adjusted to l'f2, insert the key equipped with a magnet into the hole, and place the magnet in the specified position.
The current flowing through the output circuit l becomes zero by contacting the magnetoresistive element directly or through an iron piece, and by transmitting this as a signal to the main body of the lock, the insertion rod of the vaginal lock is pulled out. You will be performing an action. In this case, it is natural that the present invention also includes a combination of a plurality of variable resistors 3.

鍵はもはや膣錠の鉋として使用する事は不可能となる。If the key is lost, stolen, or the resident changes, replace the magnet attached to the object with a magnet with a different magnetic flux density, and adjust the variable resistor again to meet the conditions of ZIZ4-Z2z3. All you have to do is satisfy. By doing this, the previous key can no longer be used as a knife for vaginal locks.
実際には、磁石が１泗の場合には、充分に差別のある磁

も本発明の範囲である。In reality, when the number of magnets is one, the number of magnet seeds distributed to each sufficiently differentiated magnetic flux density is small, which poses a problem from the standpoint of ensuring safety. In order to solve this problem, as shown in FIG. 4, a plurality of magnetoresistive elements 4-a, 4-b,
4-c and 4-d, a plurality of permanent magnets, 5-a
, 5-b, 5-c, and 5-d are also within the scope of the present invention.

において当接する様に鍵に装着される。In the figure, the magnetoresistive elements are arranged in series, but not only in series but also in parallel or series-parallel arrangement, which are all included in the present invention, and it is also possible to use a plurality of magnetoresistive elements other than the four shown in the figure. Of course, Yuba is also included in the present invention. The electrical resistance value of these magnetoresistive elements 4 in the absence of a magnetic field and the rate of change in resistance value when a magnetic field is applied can be freely selected, and the magnetic flux density of each permanent magnet 5 can also be set as follows. It can be selected freely and is attached to the key so that when the key is placed in a predetermined position in the escape hole, the magnetic resistance element 4 and the permanent magnet 5 come into contact at opposing positions.

全く異った特性の、錠と鍵の組合せが得られる事になり
、安全保証は保たれる。Even in the case of the arrangement as shown in FIG. 4, adjustment using the variable resistor 3 is easy. When it is necessary to change the lock, change the magnetic flux density of any one of the plurality of magnets and adjust the variable resistor 3 again, making the lock completely different from the previous lock. A combination of locks and keys with different characteristics can be obtained, and safety guarantees can be maintained.
この様に、複数個の磁気抵抗素子４− ａ〜４−ｄｌと
複数個の永久磁石５− ａ〜５−ｄを用いる事によって
多くの異った組合せの得られる事は容易に理解できると

ちゅうに属する事は明白である。The lock body 8 in FIGS. 5 and 6 naturally includes a drive mechanism, a power source, and equipment such as a backup power source in case of a power outage or a storage battery, but the system and structure of the drive mechanism are different. It goes without saying that the use of any number of types of power sources falls within the scope of the present invention. It is obvious that the conventional concept of housing all the components inside the door 13 and installing only the insertion holes 10 in the pillars and walls 14 also falls within the scope of the present invention.
