[Solution] The elevator comprises a car, a car rope connected to the car, a counterweight connected to the car rope, a sheave around which the car rope is wound, a brake for braking the sheave, a release input unit to which instruction information for releasing the brake is input, and a set position detection unit for detecting when the car is in a set position, and when the set position detection unit does not detect the car, the instruction information input to the release input unit is valid, and when the set position detection unit detects the car, the instruction information input to the release input unit is invalid.

Description

[Technical field]

[0001] The present specification relates to an elevator. [Background technology]

[0002] Conventionally, for example, a elevator car includes a cage, a cage rope connected to the cage, a counterweight connected to the cage rope, a sheave around which the cage rope is wound, a brake for braking the sheave, and a release input section to which instruction information for releasing the brake is input (for example, Patent Document 1).

[0003] In the elevator of Patent Document 1, for example, if the elevator breaks down, command information is input to the release input unit to release the brake, and the car and the counterweight rise and fall due to the weight difference between the car and the counterweight. Meanwhile, when the car is being moved to a desired set position, for example, if the car passes the set position, it is necessary to change the weight difference between the car and the counterweight to the opposite of the current one.

[0004] Specifically, if the car is lighter than the counterweight and the car moves above the set position while it is being raised, it is necessary to make the car heavier than the counterweight, for example, by loading a weight inside the car. Also, if the car is heavier than the counterweight and the car moves below the set position while it is being lowered, it is necessary to make the car lighter than the counterweight, for example, by removing a weight from inside the car. Therefore, the task of positioning the car at the set position becomes complicated. [Prior art documents] [Patent documents]

[0009] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions in order to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0010] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0011] Hereinafter, one embodiment of an elevator will be described with reference to Figures 1 to 9. Note that the following embodiment is provided as an example to aid in understanding the configuration of the elevator, and is not intended to limit the configuration of the elevator.

[0012] 1, elevator 1 includes, for example, a car 2 for people (passengers) to ride in, a car rope 3 connected to the car 2, and a counterweight 4 connected to the car rope 3. In addition, elevator 1 may include, for example, as in this embodiment, a processing device 5 that controls each part of elevator 1, a hoist 6 that drives the car rope 3 to run car 2 and counterweight 4 in the up-down direction D3, a car rail 7 that guides car 2, and a counterweight rail 8 that guides counterweight 4.

[0013] In this embodiment, both ends of the car ropes 3 are fixed to the hoistway X1, and the car ropes 3 are wound around the sheaves of the car 2 and the counterweight 4, respectively, thereby connecting the car ropes 3 to the car 2 and the counterweight 4, respectively. However, the present invention is not limited to such a configuration. For example, a configuration in which a first end of the car ropes 3 is fixed to the car 2, and a second end of the car ropes 3 is fixed to the counterweight 4 may also be used.

[0014] In addition, in this embodiment, the hoisting machine 6 is arranged inside the hoistway X1, but the present invention is not limited to this configuration. For example, a machine room may be provided above the hoistway X1, and the hoisting machine 6 may be arranged inside the machine room.

[0015] The hoist 6 includes a sheave 6a around which the cage rope 3 is wound, and a brake 6b for braking the sheave 6a. The hoist 6 may also include a drive source 6c (e.g., a motor) for rotating the sheave 6a, as in this embodiment.

[0016] The configuration of the brake 6b is not particularly limited as long as it can brake the sheave 6a. For example, the brake 6b may be a disk brake that brakes the sheave 6a by pressing and contacting a disk that rotates integrally with the sheave 6a so as to sandwich the disk. Also, for example, the brake 6b may be a drum brake that brakes the sheave 6a by pressing and contacting the outer circumferential surface of a drum that rotates integrally with the sheave 6a.

[0017] The processing device 5 may include a control panel 9 fixed to the hoistway X1 inside the hoistway X1, as in the present embodiment. The number of control panels 9 is not particularly limited. The number of control panels 9 may be one, as in the present embodiment, or may be two or more.

[0018] In the present embodiment, the control panel 9 is arranged inside the hoistway X1, but the present invention is not limited to this configuration. For example, a machine room may be provided above the hoistway X1, and the control panel 9 may be arranged inside the machine room.

[0019] 2 to 4, the elevator 1 may include, for example, hall doors 10 that open and close entrances to the halls X2 and X3, and a hall operating unit 32 that is arranged at the halls X2 and X3. The car 2 may include, for example, as in this embodiment, a car room 11 for passengers to board, a car frame 12 that is arranged around the car room 11 and is made of steel, car doors 13 that open and close the entrances to the car 2, and a car operating unit 33 that is arranged inside the car room 11. Note that in FIG. 2, the sheave of the car 2 around which the car rope 3 is wound is not shown.

[0020] In Figures 2 to 4, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 which is a horizontal direction perpendicular to the first horizontal direction D1, and the third direction D3 is the up-down direction D3 which is perpendicular to each of the horizontal directions D1 and D2, and is the lifting direction in which the car 2 and the counterweight 4 rise and fall.

[0021] The control panel 9 may include, for example, a panel main body 9a fixed to the elevator shaft X1, and a panel door 9b connected to the panel main body 9a so as to be movable between an open position (position indicated by a two-dot chain line in FIG. 4) and a closed position (position indicated by a dashed line in FIG. 4), as in this embodiment. Note that, for example, as in this embodiment, a part of the panel door 9b positioned in the open position may overlap with the car 2 when viewed in the vertical direction D3, and the entire panel door 9b positioned in the closed position may be separated from the car 2 when viewed in the vertical direction D3.

[0022] The elevator 1 may also include car detection units 21-23 that detect when the car 2 is located at a predetermined position. The car detection units 21-23 may, for example, include hall position detection units 21, 22 that detect when the car 2 is located at the positions of halls X2, X3, and a set position detection unit 23 that detects when the car 2 is located at a set position, as in this embodiment.

[0023] 3 shows a first hall position detection unit 21 that detects that the car 2 is located at the position of the first hall X2 (hereinafter referred to as the "first hall position"), and a second hall position detection unit 22 that detects that the car 2 is located at the position of the second hall X3 (hereinafter referred to as the "second hall position"). Note that the hall position detection units 21 and 22 may be provided for all halls, for example.

[0024] In Fig. 3(a), the cars 2 located at the first and second landing positions are illustrated by two-dot chain lines. Although not particularly limited, in this embodiment, the first landing X2 is the landing on the top floor, and the second landing X3 is the landing one floor below the first landing X2 and is the second landing from the top.

[0025] 3(b) shows the car 2 located at the set position. The set position is a position away from all the landings X2 and X3 in the vertical direction D3. For example, as in this embodiment, the set position may be configured to be a position above the second landing position and a position below the first landing position.

[0026] For example, as in this embodiment, the lower end of the control panel 9 may be arranged above the upper end of the car chamber 11 of the car 2 located at the set position, and below the upper end of the hall door 10 of the first hall X2. As a result, by positioning the car 2 at the set position, the car 2 can be positioned near the control panel 9. Therefore, for example, a worker X4 who is on top of the car 2 located at the set position can open and close the panel door 9b of the control panel 9, and can perform work on the control panel 9.

[0027] Moreover, for example, as in this embodiment, when the car 2 is located at the set position, the upper end of the car chamber 11 may be arranged below the center in the vertical direction D3 of the hall door 10 of the first hall X2 and above the lower end of the hall door 10 of the first hall X2. This allows a passenger to easily get on to the upper part of the car chamber 11 of the car 2 located at the set position by opening the hall door 10 of the first hall X2.

[0028] 5, the elevator 1 may include, for example, an input unit 31 to which various information is input, and an output unit 15 to which various information is output. Note that a hall operation unit 32 and a car operation unit 33 are included in the input unit 31 because information is input to the hall operation unit 32 and the car operation unit 33.

[0029] The input unit 31 includes a release input unit 34 to which instruction information for releasing the brake 6b is input, a first state input unit 35 to which instruction information for validating the instruction information input to the release input unit 34 is input, and a second state input unit 36 ​​to which instruction information for validating the instruction information input to the release input unit 34 is input when the set position detection unit 23 detects the car 2.

[0030] The input units 31 to 36 are not particularly limited, and may be, for example, a switch (such as a push button switch or a select switch), a touch panel, a connector, etc. The output unit 15 is not particularly limited, and may be, for example, a display unit that displays information (such as an electronic bulletin board or a display light), a sound generating unit that emits information as sound (such as a buzzer or a speaker), a signal output unit that outputs a signal to the outside (such as a central monitoring panel), etc.

[0031] Furthermore, the elevator 1 may include a storage unit 40 (see Figs. 3 and 4) that stores the release input unit 34 and the state input units 35, 36, as in this embodiment. The storage unit 40 may be disposed in the first hall X2, as in this embodiment. As a result, the storage unit 40 (the release input unit 34 and the state input units 35, 36) is disposed in the hall X2, which is the hall position that is the closest upward from the set position.

[0032] For example, the release input unit 34 and each of the state input units 35, 36 may be arranged at a landing different from the landings where the other input units 34 to 36 are arranged. Also, for example, at least one of the release input unit 34 and each of the state input units 35, 36 may be arranged at a position away from the landing (for example, inside the elevator shaft X1 or inside the car 2).

[0033] The processing device 5 may include, for example, an acquisition unit 5a that acquires each piece of information (data) from each of the units 21-23, 31-36, a storage unit 5b that stores each piece of information, a calculation unit 5c that calculates each piece of information, and a control unit 5d that controls each of the units 6b, 6c, 15. The processing device 5 may be, for example, a computer that includes a processor such as a CPU and an MPU (for example, the calculation unit 5c, the control unit 5d), memories such as a ROM and a RAM (for example, the acquisition unit 5a, the storage unit 5b), various interfaces, and the like.

[0034] As a result, the processor executes the program stored in the memory, and the software and hardware work together to realize the respective units 5a to 5d of the processing device 5. The processing device 5 may be a software circuit, a hardware circuit, or a combination of a software circuit and a hardware circuit.

[0035] The processing device 5 may be, for example, a single device, or may be, for example, a plurality of devices that can communicate with each other. Specifically, the units 5a to 5d of the processing device 5 may be, for example, provided in a single device, or may be, for example, distributed across a plurality of devices that can communicate with each other.

[0036] The configuration of the elevator 1 according to this embodiment is as described above, and next, a control method for the elevator 1 according to this embodiment will be described with reference to Figures 6 to 9. Note that the following control method is provided as an example to aid in understanding the control method for the elevator 1, and is not intended to limit the control method for the elevator 1.

[0037] The car detection units 21 to 23 are not particularly limited, and may be, for example, a limit sensor (limit switch), a proximity sensor, a photoelectric sensor, etc. In Figs. 6 to 9, the set position detection unit 23 is a limit sensor (B contact).

[0038] Further, each of the input units 34 to 36 is not particularly limited, and may be, for example, a switch (a push button switch, a select switch, etc.), a touch panel, a connector, etc. In Fig. 6 to Fig. 9, the release input unit 34 is a push button switch (A contact), and the first state input unit 35 and the second state input unit 36 ​​are connectors.

[0039] The processing device 5 may control the running of the car 2 and the opening and closing of the doors 10, 13, for example, based on information (destination floor information and door opening / closing information) input to the hall operation unit 32 and information (destination direction information) input to the car operation unit 33. The processing device 5 releases the brake 6b when the car 2 is running, and applies the brake 6b when the car 2 is stopped at the halls X2 and X3.

[0040] Incidentally, for example, when the elevator 1 breaks down, the processor 5 applies the brake 6b. Examples of such a breakdown include a breakdown of the motor inverter that is the driving source 6c, a breakdown of the power supply device in the control panel 9 that causes the CPU to stop, or a breakdown of equipment on the safety circuit of the elevator 1. In such a case, it is necessary to release the brake 6b and move the car 2 to the set position.

[0041] 6, when no instruction information is input to the first state input unit 35 (the connector is not connected), the instruction information (the push button switch is pressed) input to the release input unit 34 is invalidated. Specifically, since the first state input unit 35 is in the open state, the processing device 5 maintains the brake 6b in the braking state even if the input to the release input unit 34 becomes the closed state.

[0042] As a result, in order to release the brake 6b, not only the operation of the release input unit 34 but also the operation of the first state input unit 35 is required. Therefore, for example, it is possible to prevent the brake 6b from being released by an erroneous operation of the release input unit 34. Note that in Fig. 6 (as well as Figs. 7 to 9), the state input units 35, 36 and the set position detection unit 23 are illustrated in solid lines and marked with a "◯" when in the closed state, and are illustrated in dashed lines and marked with an "X" when in the open state.

[0043] 7, when the set position detection unit 23 does not detect the car 2 and when instruction information is input to the first state input unit 35 (the connector is connected), the instruction information input to the release input unit 34 (that the push button switch has been pressed) becomes valid. Specifically, since the first state input unit 35 and the set position detection unit 23 are in the closed state, when the input to the release input unit 34 becomes the closed state, the processing device 5 releases the brake 6b.

[0044] Therefore, the car 2 moves toward the set position by adjusting the total weight of the car 2 in advance by emptying the interior of the car 2 or loading weights into the interior of the car 2. For example, when the car 2 is located below the set position, the car 2 moves upward toward the set position by making the car 2 lighter than the counterweight 4. Conversely, when the car 2 is located above the set position, the car 2 moves downward toward the set position by making the car 2 heavier than the counterweight 4.

[0045] In this embodiment, the set position is higher than the second landing position, which is the second highest, and lower than the first landing position on the top floor, so the car 2 often stops at a position lower than the set position. Therefore, since the weight of the car 2 itself (the total weight of the car 2 when the inside of the car 2 is empty) is lighter than the weight of the counterweight 4, it is possible to reduce the number of cases where it is necessary to load weights inside the car 2 in order to move the car 2 towards the set position.

[0046] Thereafter, the car 2 moves to the set position, and the set position detection unit 23 detects the car 2. Then, as shown in Fig. 8, when the set position detection unit 23 detects the car 2, the instruction information (that the push button switch has been pressed) input to the release input unit 34 becomes invalid. Specifically, since the set position detection unit 23 and the second state input unit 36 ​​are in the open state, the processing device 5 sets the brake 6b to the braking state even if the input to the release input unit 34 is in the closed state.

[0047] As a result, when the car 2 moves to the set position, the instruction information input to the release input unit 34 becomes invalid, and the brake 6b enters a braking state. Therefore, since the car 2 stops at the set position, the car 2 can be easily positioned at the set position.

[0048] Moreover, since the set position is a position away from all the landings X2, X3 in the vertical direction D3, it is not possible to use the landings X2, X3 as a reference for positioning the car 2 at the set position. However, when the car 2 moves to the set position, the instruction information input to the release input unit 34 becomes invalid, and the brake 6b enters a braking state. As a result, the car 2 stops at the set position, and the car 2 can be easily positioned at the set position.

[0049] Furthermore, when the set position detection unit 23 detects the car 2 and no instruction information is input to at least one of the first state input unit 35 and the second state input unit 36, the instruction information input to the release input unit 34 is invalid. As a result, in order to release the brake 6b when the car 2 is located at the set position, not only the operation of the release input unit 34 but also the operation of the first state input unit 35 and the second state input unit 36 ​​are required.

[0050] Therefore, for example, when the car 2 is located at the set position, it is possible to prevent the brake 6b from being put into the released state due to an erroneous operation of the release input unit 34. As a result, for example, it is possible to prevent the car 2 from moving unnecessarily from the set position.

[0051] Incidentally, there are cases where it is desired to move the car 2 located at a set position, or to move the car 2 via a set position, etc. Although not particularly limited, examples include a case where a person (passenger) is riding in the car 2 located at a set position, and it is desired to move the car 2 to the landing X2, X3 in order to allow the person to disembark from the car 2, and a case where it is desired to move the position of the car 2 slightly in order for a worker X4 to work on the control panel 9.

[0052] 9, when instruction information is input to not only the first state input unit 35 but also the second state input unit 36 ​​(the connector is connected), the instruction information input to the release input unit 34 (that the push button switch has been pressed) becomes valid even if the set position detection unit 23 detects the car 2. Specifically, since the first state input unit 35 and the second state input unit 36 ​​are in the closed state, when the input to the release input unit 34 becomes the closed state, the processing device 5 releases the brake 6b.

[0053] As a result, the car 2 moves in the vertical direction D3 from the set position, or moves in the vertical direction D3 via the set position. Therefore, by operating not only the first state input unit 35 but also the second state input unit 36, the car 2 can be moved from the set position or moved via the set position.

[0054] [1] As described above, the elevator 1 according to the present embodiment has the following features: Basket 2 and A cage rope 3 connected to the cage 2; A counterweight 4 connected to the cage rope 3; A sheave 6a around which the cage rope 3 is wound; A brake 6b for braking the sheave 6a; a release input unit 34 to which instruction information for releasing the brake 6b is input; A set position detection unit 23 that detects that the car 2 is located at a set position, When the set position detection unit 23 does not detect the car 2, the instruction information input to the release input unit 34 is valid, When the set position detection unit 23 detects the car 2, the instruction information input to the release input unit 34 is invalid. This configuration is preferred.

[0055] According to this configuration, when the set position detection unit 23 does not detect the car 2, the instruction information input to the release input unit 34 becomes valid, and the brake 6b is released by inputting the instruction information to the release input unit 34. As a result, the car 2 moves toward the set position.

[0056] Thereafter, when the set position detection unit 23 detects the car 2, the instruction information input to the release input unit 34 becomes invalid, and the brake 6b enters a braking state. As a result, when the car 2 moves to the set position, the brake 6b enters a braking state from a released state, and the car 2 stops at the set position. Therefore, the car 2 can be easily positioned at the set position.

[0057] [2] In addition, the elevator 1 described above in [1] is, as in this embodiment, Landing doors 10 arranged at landings X2 and X3; A control panel 9 fixed to the elevator shaft X1, The car 2 includes a car compartment 11 for passengers to ride in. The set position is lower than the position of the first landing X2 and higher than the position of the second landing X3 which is one level below the first landing X2, A lower end of the control panel 9 is disposed above an upper end of the car chamber 11 of the car 2 located at the set position, and is disposed below an upper end of the landing door 10 of the first landing X2. This configuration is preferred.

[0058] According to this configuration, the set position is lower than the position of the first landing X2 and higher than the position of the second landing X3 which is one landing below the first landing X2. The lower end of the control panel 9 is disposed higher than the upper end of the car chamber 11 of the car 2 which is disposed at the set position and lower than the upper end of the landing door 10 of the first landing X2. Thus, by positioning the car 2 at the set position, the car 2 can be positioned near the control panel 9.

[0059] [3] In addition, in the elevator 1 described in [2] above, as in this embodiment, An upper end of the car chamber 11 of the car 2 located at the set position is disposed below a center of the hall door 10 of the first hall X2 in the vertical direction D3, and is disposed above a lower end of the hall door 10 of the first hall X2. This configuration is preferred.

[0060] According to this configuration, when the car 2 is located at the set position, the upper end of the car chamber 11 is disposed below the center in the up-down direction D3 of the hall door 10 of the first hall X2, and is disposed above the lower end of the hall door 10 of the first hall X2. As a result, by opening the hall door 10 of the first hall X2, it is possible to easily get on to the upper part of the car chamber 11 of the car 2 located at the set position.

[0061] [4] In addition, any one of the elevators 1 described above in [1] to [3] may be, as in this embodiment, The device further includes a first state input unit 35 to which instruction information for validating the instruction information input to the release input unit 34 is input, When the instruction information is input to the first state input unit 35, the instruction information input to the release input unit 34 is valid, When the instruction information is not input to the first state input unit 35, the instruction information input to the release input unit 34 is invalid. This configuration is preferred.

[0062] According to this configuration, when command information is input to the first state input unit 35, the command information input to the release input unit 34 becomes valid. As a result, in order to release the brake 6b, not only the operation of the release input unit 34 but also the operation of the first state input unit 35 is required.

[0063] [5] In addition, any one of the elevators 1 described above in [1] to [4] may be, as in this embodiment, Further, a second state input unit 36 ​​is provided to which instruction information for validating the instruction information input to the release input unit 34 is input when the set position detection unit 23 detects the car 2, When the set position detection unit 23 detects the car 2 and the instruction information is input to the second state input unit 36, the instruction information input to the release input unit 34 is valid, When the set position detection unit 23 detects the car 2 and the instruction information is not input to the second state input unit 36, the instruction information input to the release input unit 34 is invalid. This configuration is preferred.

[0064] According to this configuration, when the set position detection unit 23 detects the car 2 and command information is input to the second state input unit 36, the command information input to the release input unit 34 becomes valid. This makes it possible to move the car 2 from or via the set position by operating the second state input unit 36.

[0065] Furthermore, when the set position detection unit 23 detects the car 2 and no instruction information is input to the second state input unit 36, the instruction information input to the release input unit 34 is invalid. As a result, in order to release the brake 6b when the car 2 is located at the set position, not only the operation of the release input unit 34 but also the operation of the second state input unit 36 ​​is required.

[0066] [6] In addition, any one of the elevators 1 described above in [1] to [5] may be, as in this embodiment, a first state input unit 35 to which instruction information for validating the instruction information input to the release input unit 34 is input; and a second state input unit 36 ​​to which instruction information for validating the instruction information input to the release input unit 34 is input when the set position detection unit 23 detects the car 2, When the set position detection unit 23 does not detect the car 2 and the instruction information is input to the first state input unit 35, the instruction information input to the release input unit 34 is valid, When the set position detection unit 23 does not detect the car 2 and the instruction information is not input to the first state input unit 35, the instruction information input to the release input unit 34 is invalid, When the set position detection unit 23 detects the car 2 and the instruction information is input to both the first state input unit 35 and the second state input unit 36, the instruction information input to the release input unit 34 is valid, When the set position detection unit 23 detects the car 2 and the instruction information is not input to at least one of the first state input unit 35 and the second state input unit 36, the instruction information input to the release input unit 34 is invalid. This configuration is preferred.

[0067] According to this configuration, when the set position detection unit 23 does not detect the car 2 and command information is input to the first state input unit 35, the command information input to the release input unit 34 becomes valid. As a result, when the car 2 is not located at the set position, in order to release the brake 6b, not only the release input unit 34 but also the first state input unit 35 needs to be operated.

[0068] Furthermore, when the set position detection unit 23 detects the car 2 and command information is input to both the first state input unit 35 and the second state input unit 36, the command information input to the release input unit 34 becomes valid. This allows the car 2 to be moved from or via the set position by operating not only the first state input unit 35 but also the second state input unit 36.

[0069] Furthermore, when the set position detection unit 23 detects the car 2 and no instruction information is input to at least one of the first state input unit 35 and the second state input unit 36, the instruction information input to the release input unit 34 is invalid. As a result, in order to release the brake 6b when the car 2 is located at the set position, not only the operation of the release input unit 34 but also the operation of the first state input unit 35 and the second state input unit 36 ​​are required.

[0070] The elevator 1 is not limited to the configuration of the embodiment described above, and is not limited to the above-mentioned effects. Of course, various modifications can be made to the elevator 1 without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations, methods, etc. of the various modified examples described below and adopt them in the configurations, methods, etc. of the embodiment described above.

[0071] (A) The elevator 1 according to the above embodiment is configured to include one set position detection unit 23. However, the elevator 1 is not limited to such a configuration. For example, the elevator 1 may be configured to include two or more set position detection units 23.

[0072] (B) In addition, in the elevator 1 according to the above embodiment, the set position is lower than the position of the first hall X2 and higher than the position of the second hall X3 which is one hall below the first hall X2. That is, the set position is a position separated from the positions of all the halls X2 and X3 in the vertical direction D3. However, the elevator 1 is not limited to such a configuration.

[0073] For example, the set position may be at least one of the positions of the multiple landings X2 and X3. Also, for example, the set position may be the positions of all of the landings X2 and X3. According to such a configuration, for example, the landing position detection units 21 and 22 also function as the set position detection units, and the car 2 can be easily positioned at the positions of the landings X2 and X3.

[0074] (C) In addition, in the elevator 1 according to the above embodiment, the lower end of the control panel 9 is arranged above the upper end of the car chamber 11 of the car 2 located at the set position, and below the upper end of the landing door 10 of the first landing X2. However, the elevator 1 is not limited to such a configuration.

[0075] For example, the lower end of the control panel 9 may be arranged below the upper end of the car chamber 11 of the car 2 located at the set position. Also, for example, the lower end of the control panel 9 may be arranged above the upper end of the landing door 10 of the first landing X2.

[0076] (D) In ​​addition, in the elevator 1 according to the above embodiment, the upper end of the car chamber 11 of the car 2 located at the set position is disposed below the center of the hall door 10 of the first hall X2 in the vertical direction D3, and is disposed above the lower end of the hall door 10 of the first hall X2. However, the elevator 1 is not limited to such a configuration.

[0077] For example, the upper end of the car chamber 11 of the car 2 located at the set position may be arranged above the center of the landing door 10 of the first landing X2 in the up-down direction D3. Also, for example, the upper end of the car chamber 11 of the car 2 located at the set position may be arranged below the lower end of the landing door 10 of the first landing X2.

[0078] (E) Furthermore, the elevator 1 according to the above embodiment is configured to include both the first state input unit 35 and the second state input unit 36. However, the elevator 1 is not limited to this configuration.

[0079] (E-1) For example, the elevator 1 may be configured to include the first state input unit 35 and not include the second state input unit 36. In such a configuration, when the set position detection unit 23 does not detect the car 2 and instruction information is input to the first state input unit 35, the instruction information input to the release input unit 34 is valid, when the set position detection unit 23 does not detect the car 2 and instruction information is not input to the first state input unit 35, the instruction information input to the release input unit 34 is invalid, and when the set position detection unit 23 detects the car 2, regardless of whether instruction information is input to the first state input unit 35, the instruction information input to the release input unit 34 is invalid.

[0080] (E-2) Also, for example, the elevator 1 may be configured to include the second state input unit 36 ​​and not include the first state input unit 35. In such a configuration, when the set position detection unit 23 does not detect the car 2, regardless of whether or not instruction information is input to the second state input unit 36, the instruction information input to the release input unit 34 is valid when the set position detection unit 23 detects the car 2 and instruction information is input to the second state input unit 36, and when the set position detection unit 23 detects the car 2 and instruction information is input to the second state input unit 36, the instruction information input to the release input unit 34 is invalid.

[0081] (E-3) Also, for example, the elevator 1 may be configured not to include both the first state input unit 35 and the second state input unit 36. In such a configuration, when the set position detection unit 23 does not detect the car 2, the instruction information input to the release input unit 34 is valid, and when the set position detection unit 23 detects the car 2, the instruction information input to the release input unit 34 is invalid.

[0082] (F) In addition, in the elevator 1 according to the above embodiment, the processor 5 invalidates the input of instruction information to the release input unit 34, thereby invalidating the input of instruction information to the release input unit 34. However, the elevator 1 is not limited to such a configuration.

[0083] For example, the input of instruction information to the release input unit 34 may be invalidated by not inputting the instruction information to the release input unit 34 to the processing device 5 (not outputting the instruction information from the release input unit 34). Also, for example, the input of instruction information to the release input unit 34 may be invalidated by disabling input from the release input unit 34 (for example, by stopping power supply to a touch panel having the release input unit 34).

[0084] (G) Furthermore, the elevator 1 may be configured to include a storage battery that enables the brake 6b to be switched between an applied state and a released state based on input of instruction information to the release input unit 34 even during a power outage, for example.

[0085] (H) For example, the order of execution of each process, such as operations, procedures, steps, and stages, in the methods and apparatuses shown in the claims, specifications, and drawings, may be arbitrary, so long as the result of a previous process is not used in a subsequent process. For example, even if the description uses "first," "next," etc. for convenience, it does not mean that the processes must be executed in that order. [Explanation of symbols]
