　例えば、かごドア１０ａとかごドア１０ｂとが開閉動作中に停電が発生した場合、駆動制御装置２０は、かごドア１０ａとかごドア１０ｂとに開方向の力を与えない。乗場ドア３ａと乗場ドア３ｂとは、ドアクローザー８による閉方向の力によって、閉動作を行う。かごドア１０ａとかごドア１０ｂとは、乗場ドア３ａと乗場ドア３ｂとに連動して、閉動作を行う。 For example, if a power failure occurs while the car door 10a and the car door 10b are opening and closing, the drive control device 20 does not apply a force in the opening direction to the car door 10a and the car door 10b. The landing door 3a and the landing door 3b are closed by a force in the closing direction by the door closer 8. The car door 10a and the car door 10b are closed by interlocking with the landing door 3a and the landing door 3b.

　例えば、解除接点４１ａは、ａ接点である。例えば、解除接点４１ａは、第２制動接点３１ｂと抵抗器３２ａとの間に設けられる。解除接点４１ａは、操作されない場合、閉成状態である。解除接点４１ａは、操作される場合、開成状態である。 For example, the release contact 41a is an a contact. For example, the release contact 41a is provided between the second braking contact 31b and the resistor 32a. The release contact 41a is in a closed state when not operated. The release contact 41a is in an open state when operated.

For example, the release contact 41b is provided between the second braking contact 31c and the resistor 32c. The release contact 41b is in a closed state when not operated. The release contact 41b is in an open state when operated.
　機械開閉器４２は、モーメンタリ方式のスイッチである。例えば、機械開閉器４２は、図示されない検知器１１ｃに設けられる。例えば、機械開閉器４２は、複数のリンク１１ｂのうちの１つに接続される。例えば、機械開閉器４２は、バー１１ａが押し込まれている場合、操作状態となる。機械開閉器４２は、操作状態である場合、解除接点４１ａと解除接点４１ｂとを操作する。機械開閉器４２は、操作状態である場合、解除接点４１ａと解除接点４１ｂとを開成状態にする。 The mechanical switch 42 is a momentary type switch. For example, the mechanical switch 42 is provided on a detector 11c (not shown). For example, the mechanical switch 42 is connected to one of the plurality of links 11b. For example, the mechanical switch 42 is in an operating state when the bar 11a is pushed in. The mechanical switch 42 operates the release contact 41a and the release contact 41b when it is in the operating state. When the mechanical switch 42 is in the operating state, the release contact 41a and the release contact 41b are opened.
　例えば、制動解除器４０は、機械開閉器４２が操作状態である場合、解除接点４１ａと解除接点４２ｂとを開成状態に切り替える。制動解除器４０は、機械開閉器４２が操作状態である場合、制動回路を開放する。 For example, the brake release device 40 switches the release contact 41a and the release contact 42b to the open state when the mechanical switch 42 is in the operating state. The brake release device 40 opens the braking circuit when the mechanical switch 42 is in the operating state.
　以上で説明した実施の形態１によれば、エレベーターのドア装置１００は、電磁制動器３０と制動解除器４０とを備える。電磁制動器３０は、電源装置２３が遮断された場合、ドアモータ２１と電源装置２３との電気回路を開放する。電磁制動器３０は、電源装置２３が遮断された場合、抵抗器３２ａ、３２ｂ、３２ｃとドアモータ２１との閉回路である制動回路を形成する。制動解除器４０は、解除接点４１ａ、４１ｂと機械開閉器４２とを備える。制動解除器４０は、機械開閉器４２が操作された場合、制動回路を開放する。このため、停電状態においてかごドア１０ａとかごドア１０ｂとに外力を与えてドアを開ける場合、機械開閉器４２が操作されているならば、ドアモータ２１は、発電制動力を発生させない。その結果停電時に容易にかごドアを開けることができる。 According to the first embodiment described above, the elevator door device 100 includes an electromagnetic brake 30 and a brake release device 40. The electromagnetic brake 30 opens the electric circuit between the door motor 21 and the power supply 23 when the power supply 23 is shut off. The electromagnetic braker 30 forms a braking circuit that is a closed circuit between the resistors 32a, 32b, 32c and the door motor 21 when the power supply device 23 is shut off. The brake release device 40 includes release contacts 41a and 41b and a mechanical switch 42. The brake releaser 40 opens the braking circuit when the mechanical switch 42 is operated. Therefore, when the car door 10a and the car door 10b are opened by applying an external force in a power failure state, the door motor 21 does not generate a power generation braking force if the mechanical switch 42 is operated. As a result, the car door can be easily opened in the event of a power failure.
　また、制動解除器４０は、セーフティシュー１１と接続される。セーフティシュー１１のバー１１ａが押下された場合、機械開閉器４２は、操作状態になる。このため、機械開閉器４２は、容易に操作されることができる。 Further, the brake release device 40 is connected to the safety shoe 11. When the bar 11a of the safety shoe 11 is pressed, the mechanical switch 42 is put into the operating state. Therefore, the mechanical switch 42 can be easily operated.

　例えば、制動解除釦６０は、押下されることで、入状態と切状態とを切り換える。制動解除釦６０は、入状態の場合、機械開閉器４２を操作状態にする。制動解除釦６０は、切り状態の場合、図３には示されない機械開閉器４２を操作状態にしない。 For example, the braking release button 60 is pressed to switch between the on state and the off state. When the braking release button 60 is in the on state, the mechanical switch 42 is put into the operating state. When the brake release button 60 is in the off state, the mechanical switch 42 (not shown in FIG. 3) is not in the operating state.

When the brake release button 60 is pressed, the mechanical switch 42 is operated. Therefore, the mechanical switch 42 can be easily operated.
　なお、制動解除釦６０は、モーメンタリ方式のスイッチでもよい。 The braking release button 60 may be a momentary type switch.
　また、制動解除釦６０は、保守ツール５０以外の場所に設けられてもよい。例えば、制動解除釦６０は、かご２の内部の操作盤に設けられる。例えば、制動解除釦６０は、かご２の外部の図３には示されないかごドア１０ａまたはかごドア１０ｂの近傍に設けられる。 Further, the brake release button 60 may be provided at a place other than the maintenance tool 50.
