【産業上の利用分野】[Industrial applications]

本考案は電気錠に係り、特に、電気錠本体の施錠又は解錠を確実に判定できる ようにしたものに関する。 The present invention relates to an electric lock, and more particularly, to an electric lock capable of reliably determining whether the electric lock body is locked or unlocked.

【0002】[0002]

【従来の技術】[Prior Art]

現在、集合住宅等で使用される自動荷物預り装置に用いられる電気錠は、配達 要求又は発送要求があった場合に、所定の複数のボックスの電気錠本体が同時に 施錠又は解錠されるように構成されている。このように、同時に施錠又は解錠さ れる場合は、電気錠本体を駆動するソレノイドの消費電力が大きくなるため、そ のソレノイドを双安定ラッチングソレノイド型とし、各ボックスの電気錠本体を 時分割的に作動させて消費電力を低減するようにしている。 Currently, electric locks used in automatic luggage storage devices used in multi-dwelling houses, etc. are designed so that when a delivery request or a shipping request is made, the electric lock bodies of a plurality of predetermined boxes can be locked or unlocked at the same time. It is configured. In this way, when locked or unlocked at the same time, the power consumption of the solenoid that drives the electric lock body increases, so the solenoid is a bistable latching solenoid type and the electric lock body of each box is time-divisional. It is operated to reduce the power consumption.

【0003】 図4は、双安定ラッチングソレノイド1の概略構成図であり、図においてEは 電源、SWはスイッチ、C1 は施錠コイル、C2 は解錠コイル、PMは永久磁石 、2はプランジャで構成されるロックシャフト及び3は圧縮コイルばねである。FIG. 4 is a schematic configuration diagram of the bistable latching solenoid 1, in which E is a power source, SW is a switch, C1 is a locking coil, C2 is an unlocking coil, PM is a permanent magnet, and 2 is a plunger. The locked shaft and 3 are compression coil springs.

【0004】 上述の双安定ラッチグソレノイド1は、施錠指令があったときにスイッチSW がC側に所定時間、例えば300ms間移動して施錠コイルC1 に通電する。こ の通電によりロックシャフト2は永久磁石PMの吸着力に抗して吸引されて移動 する(図4において上方へ移動する。)。ロックシャフト2の移動量が所定の死 点を越えるとそのロックシャフト2は圧縮コイルばね3の作用により施錠位置に 保持される。この施錠位置においては、ロックシャフト2は図示しないロックプ レ−トの係合孔に係合して電気錠本体を施錠状態に保ち、この状態はスイッチS Wが中立状態となって施錠コイルC1 の通電が断たれても、また停電によって施 錠コイルC1 の通電が断たれても安定的に保たれる。In the above-described bistable latching solenoid 1, when a lock command is issued, the switch SW moves to the C side for a predetermined time, for example, 300 ms, to energize the lock coil C1. By this energization, the lock shaft 2 is attracted and moves against the attraction force of the permanent magnet PM (moves upward in FIG. 4). When the amount of movement of the lock shaft 2 exceeds a predetermined dead point, the lock shaft 2 is held in the locked position by the action of the compression coil spring 3. In this locking position, the lock shaft 2 engages with the engagement hole of the lock plate (not shown) to keep the electric lock body in the locked state, and in this state, the switch SW is in the neutral state and the lock coil C1 is locked. Even if the energization is cut off, or even if the locking coil C1 is cut off due to a power failure, it can be kept stable.

【0005】 他方、双安定ラッチングソレノイド1に解錠指令があったときは、スイッチS WがO側に所定時間、例えば300ms間移動して解錠コイルC2 に通電する。 この通電によりロックシャフト2は圧縮コイルばね3に抗して永久磁石PM側へ 移動する(図4において下方へ移動する。)。ロックシャフト2の移動量が所定 の死点を越えると、そのロックシャフト2は永久磁石PMに吸着されて解錠位置 に保持される。この解錠位置において、ロックシャフト2はロックプレ−トの係 合孔から外れて電気錠本体を解錠状態に保ち、この状態はスイッチSWが中立状 態となって解錠コイルD2 の通電が断たれても安定的に保たれる。On the other hand, when the bistable latching solenoid 1 receives an unlocking command, the switch SW moves to the O side for a predetermined time, for example, 300 ms to energize the unlocking coil C2. By this energization, the lock shaft 2 moves toward the permanent magnet PM side against the compression coil spring 3 (moves downward in FIG. 4). When the amount of movement of the lock shaft 2 exceeds a predetermined dead center, the lock shaft 2 is attracted to the permanent magnet PM and held at the unlocked position. In this unlocked position, the lock shaft 2 is disengaged from the engagement hole of the lock plate to keep the electric lock body in the unlocked state, and in this state, the switch SW is in the neutral state and the unlocking coil D2 is de-energized. It is kept stable even when leaned.

【0006】 上述のように、電気錠本体のソレノイドを双安定ラッチングソレノイド型とし たときは、消費電力が少なくてすみ、したがって、多数の電気錠本体を備えた自 動荷物預り装置においてはその効果は大きい。As described above, when the solenoid of the electric lock body is of the bistable latching solenoid type, it consumes less power, and therefore, the effect is obtained in the automatic baggage depositing device having a large number of electric lock bodies. Is big.

【0007】 ところが、双安定ラッチングソレノイド型の電気錠としたときは、ロックシャ フトと係合孔の位置ずれやボックス内に収納した荷物の外力により、ロックシャ フトに所定以上の負荷が加わることがあり、一回の施錠指令又は解錠指令による 施錠コイル又は解錠コイルへの通電では施錠又は解錠が行われないという不都合 がある。However, when a bistable latching solenoid type electric lock is used, a load more than a predetermined amount may be applied to the lock shaft due to the positional shift between the lock shaft and the engagement hole or the external force of the luggage stored in the box. However, there is an inconvenience that the locking or unlocking is not performed by energizing the locking coil or the unlocking coil by one locking or unlocking command.

【0008】 このような不都合を解消するために、本出願人は、先に、実願平3−3785 8号で電気錠本体の施錠又は解錠が検出されるまで、繰返し施錠指令又は解錠指 令を発する電気錠を提案した。これにより、ロックシャフトに所定以上の負荷が 加わっていても、確実に電気錠本体を施錠又は解錠することができる。In order to solve such an inconvenience, the applicant of the present invention first repeats the locking command or unlocking until the locking or unlocking of the electric lock body is detected in Japanese Patent Application No. 3-37858. He proposed an electric lock to issue a command. As a result, the electric lock body can be reliably locked or unlocked even if a load greater than a predetermined amount is applied to the lock shaft.

【0009】[0009]

【考案が解決しようとする課題】[Problems to be solved by the device]

上述のように、本出願人は電気錠本体の施錠又は解錠が検出されるまで、繰返 し施錠指令又は解錠指令を発して、確実な施錠又は解錠動作を行なわせることを 提案したが、施錠又は解錠の検出は、施錠指令又は解錠指令後、つまり所定時間 長(上述の例では300ms)を有するソレノイド駆動パルスの終了後に施錠信 号又は解錠信号の有無により行なっていたので、少なくとも上述の検出時間は所 定時間長を必要とする問題点を含んでいた。また、検出信号が上記の所定時間終 了間際に入力されたときは、エラ−検出されるおそれがあった。 As described above, the applicant has proposed to issue a repetitive locking command or an unlocking command until the locking or unlocking of the electric lock body is detected so that a reliable locking or unlocking operation is performed. However, the lock or unlock is detected by the presence or absence of the lock signal or the unlock signal after the lock command or the unlock command, that is, after the end of the solenoid drive pulse having a predetermined time length (300 ms in the above example). Therefore, at least the above detection time includes a problem that requires a fixed length of time. Further, when the detection signal is input near the end of the above-mentioned predetermined time, there is a risk of error detection.

【0010】 そこで、本考案は、上記問題点を解決するためになされたものであって、その 目的は、短時間に、かつ確実に施錠又は解錠を検出することのできる電気錠を提 供することにある。Therefore, the present invention has been made in order to solve the above problems, and an object thereof is to provide an electric lock capable of reliably detecting locking or unlocking in a short time. Especially.

【0011】[0011]

【課題を解決するための手段】[Means for Solving the Problems]

本考案に係る電気錠は、上記目的を達成するために、施錠指令又は解錠指令に 基づいてソレノイドが駆動して施錠動作又は解錠動作を行なう電気錠本体と、そ の電気錠本体の施錠動作又は解錠動作を検出する検出手段と、前記電気錠本体に 施錠指令又は解錠指令があったときに前記ソレノイドを所定時間駆動するソレノ イド駆動手段と、前記検出手段が前記電気錠本体の施錠動作又は解錠動作を検出 したときに、その検出時から所定時間経過後に、前記ソレノイド駆動手段の所定 時間に拘りなくそのソレノイド駆動手段の駆動を停止させる停止手段と、前記ソ レノイド駆動手段の駆動が停止されてから所定時間経過後に、前記検出手段の検 出信号に基づいて前記電気錠本体の施錠状態又は解錠状態を判定する判定手段と を有することを特徴としている。 In order to achieve the above object, an electric lock according to the present invention comprises an electric lock main body for performing a locking operation or an unlocking operation by a solenoid driven based on a locking instruction or an unlocking instruction, and a locking operation of the electric lock main body. A detection means for detecting an operation or an unlocking operation, a solenoid drive means for driving the solenoid for a predetermined time when the electric lock body receives a locking command or an unlocking command, and the detection means is for the electric lock body. When a locking operation or an unlocking operation is detected, a stop means for stopping the drive of the solenoid drive means regardless of a predetermined time of the solenoid drive means after a predetermined time has elapsed from the detection time, and a solenoid drive means of the solenoid drive means. And a determining means for determining a locked state or an unlocked state of the electric lock main body based on a detection signal of the detection means after a predetermined time has elapsed since the driving was stopped. It is a symptom.

【0012】[0012]

【作用】[Action]

上記構成において、電気錠本体に施錠指令又は解錠指令があると、ソレノイド 駆動手段は、ソレノイドを所定時間駆動するように作用する。そして、停止手段 は、検出手段が施錠又は解錠を検出すると、ソレノイド駆動手段が所定時間の駆 動中であってもその検出時点から所定時間経過後にそのソレノイドの駆動を停止 する。判定手段はソレノイドの駆動が停止された後、すなわち、検出手段が検出 した時点から所定時間経過後、又はソレノイド駆動手段の所定時間経過後に、検 出手段の検出信号に基づいて電気錠本体の動作状態、つまり施錠状態あるいは解 錠状態を検出する。 In the above configuration, when the electric lock main body receives a locking command or an unlocking command, the solenoid drive means operates to drive the solenoid for a predetermined time. Then, when the detecting means detects locking or unlocking, the stopping means stops the driving of the solenoid even after the solenoid driving means has been driven for a predetermined time and after a predetermined time has elapsed from the detection time. The determination means operates the electric lock main body based on the detection signal of the detection means after the solenoid drive is stopped, that is, after a predetermined time has passed from the time when the detection means detects, or after the predetermined time of the solenoid drive means. The state, that is, the locked state or the unlocked state is detected.

【実施例】【Example】

以下、本考案の実施例を図面に基づいて説明する。なお、上記図4で示した同 一構成要素については、同一符号を用いて説明する。 Embodiments of the present invention will be described below with reference to the drawings. The same components shown in FIG. 4 will be described using the same reference numerals.

【0014】 図1は、本考案にかかる電気錠本体aを収納ボックスに適用したときの要部の 縦断面図である。同図において、4はボックス本体、5はボックス本体4の開口 面に蝶番(図示せず)により開閉自在に取り付けられた扉、6は扉5の内側に溶 接で固定されたロックプレ−ト、7はロックプレ−ト6に形成された係合孔、8 はボックス本体4の開口を形成する周壁の前面壁であり、この全面壁8の裏面に 取付部材1Aを介して双安定ラッチングソレノイド1が取付けられている。双安 定ラッチングソレノイド1の内部には、施錠コイルC1 、解錠コイルC2 及び永 久磁石PM(図1には図示せず)が収容されているとともに、圧縮コイルばね3 を備えたロックシャフト2がロックプレ−ト7の係合孔6に対向させて設けられ ている。FIG. 1 is a vertical cross-sectional view of a main part when the electric lock body a according to the present invention is applied to a storage box. In the figure, 4 is a box body, 5 is a door attached to the opening surface of the box body 4 by a hinge (not shown) so as to be openable and closable, 6 is a lock plate fixed to the inside of the door 5 by welding, Reference numeral 7 is an engagement hole formed in the lock plate 6, 8 is a front wall of a peripheral wall forming an opening of the box body 4, and the bistable latching solenoid 1 is provided on the back surface of the entire surface wall 8 through a mounting member 1A. Installed. A lock coil C1, an unlock coil C2 and a permanent magnet PM (not shown in FIG. 1) are housed inside the bi-stable latching solenoid 1 and a lock shaft 2 having a compression coil spring 3 is housed therein. Is provided so as to face the engagement hole 6 of the lock plate 7.

【0015】 S1 ,S2 はボックス本体4側に設けられたマイクロスイッチからなるセンサ であり、このうちS1 は、ロックプレ−ト6によってON,OFFされ、扉5の 開閉状態を検知する扉センサ、またS2 は、ロックシャフト2に接続されたア− ム9の上下移動によってON,OFFされ、解錠と施錠のいずれの状態を検知す る錠センサで本考案の検出手段に該当している。S1 and S2 are sensors formed by a micro switch provided on the box body 4 side. Among them, S1 is a door sensor that is turned on and off by a lock plate 6 to detect the open / closed state of the door 5, and S2 is a lock sensor that is turned on and off by the vertical movement of the arm 9 connected to the lock shaft 2 and detects either the unlocked state or the locked state, and corresponds to the detection means of the present invention.

【0016】 図中10は、マイクロコンピュ−タを含んで構成され、本考案のソレノイド駆 動手段、停止手段及び判定手段の機能を有する制御器であって、両センサS1 , S2 の検出信号を入力するとともに、施錠コイルC1 及び解錠コイルC2 へ駆動 電流を供給できるように構成されている。また、図示しないが、制御器10には 、周知の電気錠と同じく、キ−カ−ドリ−ダ又はテンキ−からなる施錠指令又は 解錠指令の入力機器が接続されている。In the figure, reference numeral 10 denotes a controller including a microcomputer and having the functions of a solenoid driving means, a stopping means and a judging means of the present invention, which detects detection signals from both sensors S1 and S2. It is configured so that a drive current can be supplied to the locking coil C1 and the unlocking coil C2 while being input. Although not shown, the controller 10 is connected with an input device for a lock command or an unlock command, which is composed of a key feeder or a numeric keypad, like the well-known electric lock.

【0017】 図2は、本実施例に係る電気錠のタイムチャ−ト及び図3はその制御動作を示 すフロ−チャ−トっである。以下、これら図面を参照しながら制御動作を説明す る。FIG. 2 is a time chart of the electric lock according to this embodiment, and FIG. 3 is a flow chart showing the control operation thereof. The control operation will be described below with reference to these drawings.

【0018】 今、扉5は、図1に示されるように閉じられた状態にあり、かつ施錠状態にあ るとする。従って、センサS1 はロックプレ−ト6がボックス本体4側に突出し ているのでOFF状態にあり、またセンサS2 はロックシャフト2が突出してい るのでア−ム9を介してON状態にある。Now, it is assumed that the door 5 is in a closed state as shown in FIG. 1 and is in a locked state. Therefore, the sensor S1 is in the OFF state because the lock plate 6 projects toward the box body 4, and the sensor S2 is in the ON state through the arm 9 because the lock shaft 2 projects.

【0019】 このとき、入力機器から解錠指令が与えられたとすると(図3のステップ10 0肯定。以下、ステップをSとする。)、制御器Cは解錠コイルC2 に所定時間 、例えば300ms駆動電流を与える(S102。図2(a),(b)の(イ)参 照)。この所定時間は、扉5に多少の外圧が加わっていてもロックシャフト2が 十分に作動できる時間により決められている。従って、扉5に何ら外圧が加わっ ていないときは、この所定時間の数分の一、例えば10msでロックシャフト2は 係合孔7からはずれて解錠状態となり、永久磁石PMに吸着される。At this time, if an unlock command is given from the input device (Yes in step 100 of FIG. 3, hereinafter, step is S), the controller C causes the unlock coil C2 to have a predetermined time, for example, 300 ms. A drive current is applied (S102. See (a) in FIGS. 2A and 2B). This predetermined time is determined by the time during which the lock shaft 2 can fully operate even if some external pressure is applied to the door 5. Therefore, when no external pressure is applied to the door 5, the lock shaft 2 is disengaged from the engagement hole 7 and unlocked within a fraction of this predetermined time, for example, 10 ms, and is attracted to the permanent magnet PM.

【0020】 図2(a)は所定時間の300ms以内にロックシャフト2が作動してセンサS 2 がOFFとなった状態を示し、また図2(b)は所定時間の300ms内に外圧 のためにロックシャフト2が作動できない状態を示している。FIG. 2A shows a state in which the lock shaft 2 is activated and the sensor S 2 is turned off within 300 ms of a predetermined time, and FIG. 2B shows that the external pressure is applied within 300 ms of the predetermined time. Shows the state where the lock shaft 2 cannot operate.

【0021】 さて、所定時間内の300ms内にロックシャフト2が作動してセンサS2 がO FFとなった場合は(図2(a)の(ロ)参照。S104肯定)、制御器10は 、その時点から所定時間経過後、例えば30ms後、解錠コイルC2 への電流供給 を停止させる(図2(a)の(ハ)参照。S106肯定。S110)。すなわち 、制御器10は、センサS2 がロックシャフト2の動作を検出し、しかもそのロ ックシャフト2が永久磁石PMに吸着されて安定した状態になった時に解錠コイ ルC2 の電流を停止する。つまり、この所定時間の30msは、ロックシャフト2 の移動動作に要する十分な時間である。When the lock shaft 2 operates within 300 ms within a predetermined time and the sensor S2 becomes OFF (see (b) of FIG. 2 (a), S104 affirmative), the controller 10: After a lapse of a predetermined time from that time, for example, 30 ms later, the current supply to the unlocking coil C2 is stopped (see (c) of FIG. 2A, S106 affirmative, S110). That is, the controller 10 stops the current of the unlocking coil C2 when the sensor S2 detects the operation of the lock shaft 2 and the lock shaft 2 is attracted to the permanent magnet PM and becomes stable. That is, the predetermined time of 30 ms is a sufficient time required for the movement operation of the lock shaft 2.

【0022】 次いで、解錠コイルC2 への電流供給が停止されてから所定時間経過後、例え ば30ms後にセンサS2 がOFFになっているかが検出される(図2(a)の( ニ)参照。S112肯定。S114)。この検出で、センサS2 がONになって いなければ(S114否定)、電気錠本体aが解錠指令されたことによってロッ クシャフト2が正常に作動し、解錠動作が終了したことを意味する。したがって 、この場合は、扉5の前面に設けられた図示しない青色ランプが制御器10によ り点灯される。Then, it is detected whether or not the sensor S2 is turned off after a predetermined time has passed since the current supply to the unlocking coil C2 was stopped, for example, 30 ms later (see (d) in FIG. 2 (a)). S112 is affirmative and S114). If the sensor S2 is not turned on by this detection (No at S114), it means that the lock shaft 2 operates normally due to the unlock command of the electric lock body a, and the unlock operation is completed. .. Therefore, in this case, a blue lamp (not shown) provided on the front surface of the door 5 is turned on by the controller 10.

【0023】 ところが、扉5に限度以上の外圧が加わっていたり、解錠コイルC2 が切断す る等のトラブルがある場合は、所定の300msが経過しても解錠コイルC2 によ ってロックシャフト2がセンサS2 をOFFとしない事態が生ずる(S104否 定。S108肯定)。However, if there is a problem such as an external pressure exceeding the limit being applied to the door 5 or disconnection of the unlocking coil C2, the unlocking coil C2 locks even if the predetermined 300 ms has elapsed. A situation occurs in which the shaft 2 does not turn off the sensor S2 (No in S104, Yes in S108).

【0024】 この場合においても、所定の300ms経過後は、解錠コイルC2 への電流供給 は断たれる(S110)。そして、上述したように、解錠コイルC2 への電流供 給が断たれた後の所定時間(30ms) 経過後に、サンサS2 の状態が検出される 。この場合は、扉5の前面に設けられた図示しない赤色ランプが制御器10によ り点滅された係員に報知されて異常処理が行われる(S114否定。S116) 。Also in this case, the current supply to the unlocking coil C2 is cut off after a lapse of the predetermined 300 ms (S110). Then, as described above, the state of the sensor S2 is detected after a lapse of a predetermined time (30 ms) after the current supply to the unlocking coil C2 is cut off. In this case, a red lamp (not shown) provided on the front surface of the door 5 is notified by the controller 10 to the blinked clerk to perform the abnormality processing (No at S114, S116).

【0025】 ごくまれではあるが、ロックシャフト2の作動が扉5の外圧の関係で、所定の 300ms終了間際に行われることがある(図2(b)のセンサS2 の鎖線の検出 信号)。この場合でも、センサS2 のON,OFFによる電気錠本体aの作動状 態の判定は、所定の300ms終了した後、さらに所定時間(30ms) 経過したと きに行なわれるので、正確な判定を行なうことができる(図2(b)の(ニ)参 照)。Although very rare, the operation of the lock shaft 2 may be performed just before the end of a predetermined 300 ms due to the external pressure of the door 5 (a detection signal of the chain line of the sensor S2 in FIG. 2B). Even in this case, the operating state of the electric lock main body a is determined by turning the sensor S2 ON and OFF when the predetermined time (30 ms) has elapsed after the predetermined 300 ms has been completed, so an accurate determination is made. It is possible (see (d) in Fig. 2 (b)).

【0026】 以上の説明は、電気錠本体aの解錠動作の説明であるが、施錠動作の場合は、 センサS1 ,S2 の動作が逆になるだけで、それ以外は解錠動作と同じなので、 これ以上の説明は省略する。The above description is for the unlocking operation of the electric lock main body a. However, in the case of the locking operation, the operations of the sensors S1 and S2 are only reversed, and the other operations are the same as the unlocking operation. , Further description is omitted.

【0027】 以上のように、本実施例に係る電気錠は、施錠コイルC1 又は解錠コイルC 2 へ所定時間駆動電流を供給しているときに、センサS2 がON又はOFFした ときから所定時間後に、施錠コイルC1 又は解錠コイルC2 への電流を停止させ るようにしたので、ロックシャフト2の動作時間を加味して安定的に作動させな がら、電気錠本体aの施錠操作時間又は解錠操作時間を短縮することができる。 例えば、施錠コイルC1 又は解錠コイルC2 に一律に300ms駆動電流を供給し た場合に比べ、扉5に外圧がなければ80msで足りる。As described above, the electric lock according to the present embodiment, when the drive current is supplied to the locking coil C 1 or the unlocking coil C 2 for a predetermined time, the predetermined time from when the sensor S 2 is turned on or off. After that, since the current to the locking coil C1 or the unlocking coil C2 was stopped, the operating time of the electric lock body a or the unlocking operation of the electric lock body a was released while the operating time of the lock shaft 2 was taken into consideration for stable operation. The lock operation time can be shortened. For example, 80 ms is sufficient if there is no external pressure on the door 5, as compared with the case where a driving current is uniformly supplied to the locking coil C1 or the unlocking coil C2 for 300 ms.

【0028】 また、電気錠本体aの動作状態の判定は、施錠コイルC1 又は解錠コイルC 2 への電流供給停止後、所定時間経過した後に行なうようにしたので、その電流 供給停止間際にロックシャフト2が作動した場合でも正確に作動状態を検出でき 、判定ミスを防止することができる。Further, the operation state of the electric lock main body a is determined after a lapse of a predetermined time after the supply of the current to the locking coil C 1 or the unlocking coil C 2 is stopped. Even if the shaft 2 operates, the operating state can be accurately detected, and it is possible to prevent erroneous determination.

本考案にかかる電気錠は、施錠指令又は解錠指令に基づいてソレノイドが駆動 して施錠動作又は解錠動作を行なう電気錠本体と、その電気錠本体の施錠動作又 は解錠動作を検出する検出手段と、前記電気錠本体に施錠指令又は解錠指令があ ったときに前記ソレノイドを所定時間駆動するソレノイド駆動手段と、前記検出 手段が前記電気錠本体の施錠動作又は解錠動作を検出したときに、その検出時か ら所定時間経過後に、前記ソレノイド駆動手段の所定時間に拘りなくそのソレノ イド駆動手段の駆動を停止させる停止手段と、前記ソレノイド駆動手段の駆動が 停止されてから所定時間経過後に、前記検出手段の検出信号に基づいて前記電気 錠本体の施錠状態又は解錠状態を判定する判定手段とからなるので、電気錠本体 の動作時間を加味してソレノイドの駆動が停止されるから電気錠本体を確実に作 動させることができる。しかも、ソレノイドの駆動停止は検出手段の検出に基づ いて行われるので、電気錠本体の操作時間を短縮することができる。また、電気 錠本体の動作状態の判定は、ソレノイドの駆動が停止されてから所定時間経過後 に行われるので、ソレノイドへの駆動終了間際にソレノイドが作動しても正確に 検出でき、判定ミスを防止することができる。 The electric lock according to the present invention detects an electric lock body that is operated by a solenoid based on a locking command or an unlocking command to perform a locking operation or an unlocking operation, and a locking operation or an unlocking operation of the electric lock body. A detection means, a solenoid drive means for driving the solenoid for a predetermined time when a lock command or an unlock command is given to the electric lock body, and the detection means detects a locking operation or an unlocking operation of the electric lock body. When a predetermined time elapses from the time of the detection, the stop means for stopping the drive of the solenoid drive means regardless of the predetermined time of the solenoid drive means, and the predetermined time after the drive of the solenoid drive means is stopped The operating time of the electric lock main body is added because it comprises a judgment means for judging the locked state or the unlocked state of the electric lock body based on the detection signal of the detection means after a lapse of time. Driving the solenoids can be reliably created dynamic electric lock body from being stopped. Moreover, since the driving of the solenoid is stopped based on the detection of the detection means, the operation time of the electric lock body can be shortened. In addition, the operating status of the electric lock itself is determined after a lapse of a predetermined time after the solenoid drive is stopped, so it can be accurately detected even if the solenoid is actuated just before the drive to the solenoid is completed, and a mistake in the determination can be made. Can be prevented.
