JP7004084B2 - Elevator control panel - Google Patents

Description

The present disclosure relates to an elevator control panel installed in an elevator hoistway.

Machine room-less elevators that secure space by eliminating the machine room that houses the hoisting machine and control panel for operating the elevator are becoming widespread.

In a machine room-less elevator, the control panel is installed in a narrow hoistway, so it is necessary to devise ways to carry it in and arrange it. For example, in Patent Document 1, the functions of the control panel are divided into those for the main circuit, those for the battery, and the like, and are arranged vertically on the guide rail so that they can be accommodated in a narrow hoistway. In addition, since the thickness of the separated panels differs for each function, the door surfaces are aligned and the distance from the work position to the work location is aligned to improve workability during maintenance and inspection of the control panel and failure repair. ..

Japanese Patent Application Laid-Open No. 2003-20171

However, not only is the inside of the hoistway narrow, but the illuminance cannot be secured, so workability during maintenance and inspection and repair is poor, and there is a risk that complicated wiring may be mistakenly connected or the wiring may be damaged. ..

This disclosure is made to solve the above-mentioned problems, and provides an elevator control panel capable of improving work quality such as maintenance inspection and failure repair of the elevator control panel installed in the elevator hoistway. The purpose.

The elevator control panel according to the present disclosure integrally includes a housing having a door portion arranged in the hoistway of the elevator in which the car is raised and lowered, and an electric component for driving which is arranged in the housing and raises and lowers the car. The formed drive unit, the control unit arranged below the drive unit in the housing, and the control electric component integrally formed to control the drive unit, and the power of the drive unit. The lines and the signal lines of the drive unit and the control unit are aggregated and housed, respectively, in the housing, on the opposite side of the door unit to the control unit , and on the lower side of the drive unit. It is provided with a wiring unit to be arranged.

According to the present disclosure, since the power lines and signal lines of the elevator control panel are aggregated and housed in the rear part of the housing as the aggregated power lines and the aggregated signal lines, the operator for maintenance inspection or failure repair is irrelevant to the work. It is possible to improve work quality by preventing accidental connection or damage without touching the aggregated power line and aggregated signal line.

Represents A cross section. In the figure, the X axis indicates the width direction of the elevator control panel 100, and the Z axis indicates the height direction. The Y-axis indicates the depth, the −Y direction indicates the front of the elevator control panel 100, and the + Y direction indicates the rear.

The elevator control panel 100 includes a drive unit 1 and a control unit 2 in the ascending / descending direction inside a housing 8 having a door portion 9, and these power lines and signal lines are integrated into an aggregated power line and an aggregated signal, respectively. As a line, it is arranged on the rear side of the control unit 2, that is, on the wiring unit 6 on the side opposite to the door unit 9 with respect to the control unit 2. The door portion 9 may be not only a door that rotates and opens and closes, but also a door that can be easily removed to check the inside.

As shown in the front view (FIG. 2B) of the housing 8 in which the door portion 9 is opened, the drive unit 1 and the control unit 2 in which the electric components form units, respectively, are inside the housing 8 for each function. Arranged vertically. Here, the unit is an integrated electric component required for each function. Each unit has a base 39 on which electrical components are placed, and has a notch 10 in a portion thereof. In the following description, an example is shown in which the drive unit 1 and the control unit 2 are unitized separately and arranged in the elevator control panel 100, but the drive unit 1 and the control unit 2 may be integrated.

The power line 63 of the drive unit 1, the signal line 64 of the drive unit 1 and the control unit 2 pass through the notch portion 10, and are integrated and housed in the wiring unit 6. A plurality of cutout portions 10 may be provided. Further, the power line 63 and the signal line 64 may be integrated without providing the notch portion 10.

Then, as shown in the cross-sectional view taken along the line AA (FIG. 2C) of FIG. The wiring portion 6 is arranged at a position sandwiched between the portions 9 and the wiring portion 6. Other units such as the battery unit 3 and the incidental unit 5, which will be described later, can be arranged below the drive unit 1 and the control unit 2 in the figure, if necessary.

An example of connection between the drive unit 1 and the wiring unit 6 arranged at the rear of the housing 8 is shown in FIG. 3 showing the right side surface of the housing 8. The power line 63 and the signal line 64 of the drive unit 1 are electrically connected to the aggregated power line 61 and the aggregated signal line 62 housed in the wiring unit 6 via the connector 11 which is a connecting unit. In FIG. 3A, the signal line 64 is on the back side, and only the power line 63 is shown.

Here, the connector 11 may be provided downward from the drive unit 1 as shown in FIG. 3A, or may be provided sideways as shown in FIG. 3B.

In this way, the power line 63 and the signal line 64 of the elevator control panel 100 are aggregated and housed in the rear part of the housing 8 as the aggregated power line 61 and the aggregated signal line 62, so that the operator for maintenance inspection or failure repair Does not touch the aggregated power line 61 and the aggregated signal line 62 unrelated to the work, prevents accidental connection or damage, and can improve the work quality.

FIG. 4 shows a connection example of an elevator control panel 100 including a battery unit 3 and an accessory unit 5 in addition to the drive unit 1 and the control unit 2. For example, the drive unit 1 converts an AC signal from the three-phase power supply 21 into a direct current and converts it into an alternating current again to drive the motor 701 in the hoisting machine 700. The control unit 2 controls the drive unit 1, and the drive unit 1 and the control unit 2 are housed in the housing 8 of the elevator control panel 100.

In the example of FIG. 4, it further has a battery unit 3 that supplies electric power to the drive unit 1 and the control unit 2, and an accessory unit 5 that controls lighting or the like, which is a peripheral device 23, for example. These are mounted on the base 39 and integrated for each function to form a unit, and the power line 63 (solid line) and the signal line 64 (broken line) in the unit are integrated into the integrated power line 61 (solid line) and the integrated power line 61 (solid line). It is housed in the wiring portion 6 as an aggregate signal line 62 (broken line).

Here, the aggregated power line 61 (solid line) and the aggregated signal line 62 (broken line) in which the plurality of power lines 63 and the signal lines 64 are aggregated are connected to at least two or more units, respectively. Further, the aggregated power line 61 and the aggregated signal line 62 are each made into a harness. That is, the ends of the aggregate power line 61 and the aggregate signal line 62 are grouped by a connector, a terminal, or the like.

Since the aggregated power line 61 and the aggregated signal line 62 are harnessed, they have a role as a harness for electrically connecting the battery unit 3 and the incidental unit 5 in addition to the drive unit 1 and the control unit 2. .. That is, it can be said that the wiring portion 6 is arranged in the space on the back side of each unit, and the aggregated power line 61 (solid line) and the aggregated signal line 62 (broken line) are arranged.

FIG. 4 shows an example in which the drive unit 1 is connected to the regenerative resistor 22 outside the elevator control panel 100, and the control unit 2 and the incidental unit 5 are connected to the peripheral device 23 outside the elevator control panel 100.

FIG. 5 shows an example of the circuit of the drive unit 1. The drive unit 1 includes, for example, a diode converter 24, a smoothing capacitor 25, a resistor 26, a transistor 27, an inverter 28, and a gate drive circuit 29. The diode converter 24 is a diode module 30, and the resistor 26, the transistor 27, and the inverter 28 are inverter circuits. It is modularized as a module 31 and mounted on the base 39 together with the smoothing capacitor 25 and the gate drive circuit 29 to form the drive unit 1.

The drive unit 1 in which the drive electrical components are integrated to form a unit in this way converts the three-phase power supply 21 received from the building in which the elevator is installed into direct current by the diode converter 24, and converts the converted direct current into an inverter. It is converted into alternating current again by 28, and the motor 701 of the hoist 700 is driven.

6A and 6B are schematic configuration diagrams showing a mounting example of the control unit 2. FIG. 6A is a control unit 2 housed in a housing 8 and mounted on a base 39, and FIG. 6B is FIG. The right side surface of (a) is shown. The control unit 2 integrates the control electrical components of the control board 32, the breaker 33, the magnetic contactor 34, and the power supply 35 to form a unit, and controls the current and voltage for the drive command to the drive unit 1. ..

These control electrical components are mounted, for example, on a base 39 having screw holes 36 at the four corners. For example, the signal lines 64 of each of these electrical components are grouped into a connector 12 which is a connection portion, pass through a notch portion 10 provided in the base 39, and are aggregated to form an aggregated signal line 62 at the rear of the housing 8. It is stored in the wiring unit 6. The connector 12 may be divided into two or more.

In the drive unit 1 and the control unit 2, the connectors 11 and 12 that aggregate the power line 63 and the signal line 64 are easily detachable, for example, if they are in the form of a dynamic connector, the drive unit 1 and the control unit 2 are It is more preferable that each of the constituent units can be separated and carried to a bright place for maintenance, inspection, and repair.

Further, only the power line 63 of the drive unit 1 may be aggregated, or the power line 63 and the signal line 64 of the drive unit 1 and the control unit 2 or a part thereof may be integrated.

The vertical positional relationship between the drive unit 1 and the control unit 2 is not limited, but the drive unit 1 is preferably arranged above the control unit 2. As a result, the heat of the drive unit 1 can be efficiently discharged.

The drive unit 1 has the largest calorific value per unit volume in the elevator control panel 100, and tends to have a high temperature. Therefore, by arranging the drive unit 1 above the control unit 2, the air warmed by the heat generated by the drive unit 1 does not come into contact with other parts in the elevator control panel 100, and above the drive unit 1. That is, it can be released above the elevator control panel 100. As a result, the heat dissipation performance of the drive unit 1 is improved, so that the elevator control panel 100 can be miniaturized. Further, since the ambient air temperature of the control unit 2 does not rise, the parts of the control unit 2 can be used at a safe temperature, and a failure can be suppressed.

Further, the drive unit 1 has an inverter circuit for driving the hoisting machine 700, and the semiconductor element is switched at high speed. Therefore, when the signal line 64 is arranged close to the drive unit 1, electromagnetic noise interferes with the signal line 64 from the drive unit 1 and is included in the control unit 2 and the incidental unit 5 via the signal line 64. Although there is a possibility that the device may malfunction, by arranging the drive unit 1 above the control unit 2, electromagnetic noise interference between the control unit 2 and the drive unit 1 can be suppressed.

Further, by arranging the drive unit 1 above the control unit 2, the control unit 2 and the incidental unit 5 can be arranged close to each other. As a result, many signal lines 64 are connected to the connection between the control unit 2 and the accessory unit 5, so that the aggregated signal line connecting the control unit 2 and the accessory unit 5 due to the electromagnetic noise generated from the drive unit 1 Interference with the 62 can be suppressed, and the parts of the control unit 2 and the incidental unit 5 can be used in a safe state, so that a failure can be suppressed.

Embodiment 2.
FIG. 7 is a schematic configuration diagram showing an elevator control panel according to the second embodiment. In the first embodiment, the control unit 2 has a function of a drive command to the drive unit 1, but here, a command unit 4 having a CPU is provided as a separate body. For example, the command unit 4 issues a command to the control unit 2 to control the operating speed of the elevator, and uses information on the drive status of the inverter 28 obtained from the drive unit 1, that is, the drive status of the hoist 700 as a current value. Perform appropriate operation management by getting feedback.

The battery unit 3 is a unit in which electric components for power supply related to elevator operation in the event of a power failure are integrated. The elevator has a function of moving the car 300 to the nearest floor and safely disembarking passengers when the car 300 stops moving up and down during a power outage. In order to realize this function, the battery unit 3 supplies electric power to the drive unit 1 and the control unit 2 to raise and lower the elevator car 300.

Although the incidental portion 5 shows an example of controlling lighting in the first embodiment, a unit that realizes other functions may be mounted on the incidental portion 5. For example, it is equipped with a group management function when multiple elevators are installed in parallel, an operation function of a landing push button board that manages the destination of the car 300, and various functions that realize specifications to comply with overseas regulations. May be good.

The ancillary portion 5 is mainly connected to the command unit 4, and in addition to the command for realizing the above-mentioned functions, the command related to the operation of the elevator such as the door operation command of the car 300, the safety switch operation command, or the peripheral device 23 is related. The command is sent to the command unit 4.

Similar to the control unit 2 of the first embodiment, the battery unit 3, the command unit 4, and the incidental unit 5 are integrally mounted on the base 39 with electrical components that realize their respective functions to form a unit. Then, the power line 63 and the signal line 64 are passed through the notch portion 10 of the base 39, and the power lines 63 and the signal lines 64 are aggregated, and the aggregated power lines 61 and 62 are housed in the wiring portion 6 as the aggregated power lines 61 and 62. To. Here, all the power lines 63 and the signal lines 64 may be collectively housed in the wiring unit 6, or a part of them may be housed. At least the signal lines 64 may be integrated and housed in the wiring unit 6.

Each of these may be arranged in the ascending / descending direction, but the command portion 4 and the incidental portion 5 may be designed thinly and arranged on the housing 8 so as to be stacked in the front-rear direction. For example, the command unit 4 and the incidental portion 5 have the command portion 4 and the incidental portion 5 on the door portion 9 side of the housing 8 as shown in FIG. 7 (b) which is a sectional view taken along the line BB of FIG. The wiring portion 6 may be arranged on the rear side of these. Although the example in which the command unit 4 and the incidental unit 5 are arranged in an overlapping manner is shown, other units may be arranged in an overlapping manner.

With this configuration, the housing 8 can be miniaturized.

FIG. 8 is a schematic configuration diagram showing a method of fixing the control unit according to the second embodiment. 8 (a) is a view taken out from a horizontal cross section of the installation position of the control unit 2 in the housing 8, FIG. 8 (b) is a front view of the housing 8 with the door portion 9 removed, and FIG. 8 (c) is a casing. It is a figure which shows a part of the right side of a body 8, and is seeing through the control part 2 shown by the broken line.

Inside the housing 8, for example, two unit mounting plates 37 are mounted so as to connect the right side surface and the left side surface of the housing 8. Both ends of the unit mounting plate 37 are bent in an L shape toward the door portion 9 side of the housing 8, and are fixed to the housing 8 by using fasteners 38 such as rivets and screws. Further, the control unit 2 is attached to the housing 8 by fastening the screw holes 36 of the base 39 and the screw holes 36 provided in the unit mounting plate 37.

By adopting such a fixing method, a large space can be taken for the wiring portion 6. When the fixing portion of the unit is provided at the rear portion of the housing 8, a region for attaching the fixing portion and its fixing parts (screws, etc.) is required, and the wiring portion becomes smaller in the lateral direction. That is, the size of the wiring portion in the X direction is smaller than the size of the housing 8 in the X direction.

However, by providing the fixing portions on the right side surface and the left side surface of the housing, a sufficient space for the wiring portion 6 can be provided. That is, the X-direction size of the housing 8 and the X-direction size of the wiring portion 6 can be made substantially the same width.

By providing a sufficient space for the wiring portion 6, the distance between the aggregated power line 61 and the aggregated signal line 62 can be sufficiently separated, so that electromagnetic noise interference between the power line and the signal line is reduced, and the equipment malfunctions. Can be prevented. Further, by increasing the space of the wiring portion 6, the cooling performance of the integrated power line 61 is improved, and the elevator control panel 100 can be used at a safe temperature. Further, due to the high cooling performance, the wiring diameter used for the integrated power line 61 can be reduced.

Further, by adopting the above-mentioned fixing method, the rigidity of the elevator control panel 100 can be increased. Since the prismatic structure can be formed on the projection surface by the back surface, the right side surface, the left side surface, and the base 39 of the unit, the rigidity of the elevator control panel 100 against rolling (X direction and Y direction) is improved. As a result, even if a large vibration is applied to the elevator control panel 100 in the event of an earthquake or the like, damage to the housing 8 can be suppressed and the elevator can operate safely.

The aggregated power line 61 and the aggregated signal line 62 are arranged on the back side of the unit mounting plate 37, that is, on the rear portion of the housing 8, and serve as the wiring portion 6. Here, the example in which the aggregated power line 61 and the aggregated signal line 62 are fixed on the base 39 is shown, but the base 39 may not be used. Further, the battery unit 3, the command unit 4, and the incidental unit 5 can also be attached to the housing 8 by the same method.

Further, FIG. 9 is another example in which the horizontal cross section of the installation position of the control unit 2 in the housing 8 is taken out, and those with the same reference numerals as those in FIG. 8 show the same or corresponding configurations, and the description thereof will be described. Is omitted. As shown in FIG. 9, instead of the base 39, a bending portion 41 and a cover member 40 having a cover portion covering the aggregated power line 61 and the aggregated signal line 62 are provided, and the aggregated power line 61 and the aggregated signal line 62 are provided on the cover member 40. The signal line 62 is arranged.

The bent portion 41 of the cover member 40 is attached to the side surface of the housing 8 by using an L-shaped sheet metal 42. FIG. 10 is a perspective view showing an example of the cover member 40, and the screw holes are omitted.

By arranging the fastening component 38 on the side surface of the housing 8 in this way, the outer back surface of the housing 8 can be formed into a flat shape.

Further, as shown in FIGS. 11A and 11B, each connector of the drive unit 1, the control unit 2, the battery unit 3, the command unit 4, and the incidental unit 5 is connected to the side surface of the cover member. A connector 161 may be provided, and a power connector 17 and a signal connector 18 may be provided at the upper end and the lower end.

Here, the bent portion 41 of the cover member 40 is continuously formed, and the side surface on which the connector 161 is provided is made vertical so as to be continuous with the cover portion.

FIG. 12 is a schematic configuration diagram showing an elevator control panel. Those having the same reference numerals as those in FIG. 8 indicate the same or corresponding configurations, and the description thereof will be omitted. FIG. 12A is a view showing a horizontal cross section of the installation position of the control unit 2 in the housing 8 of the elevator control panel 100 using the cover member 40, and FIG. 12B is the housing 8 with the door portion 9 removed. 12 (c) is a front view of FIG. 12 (b), in which the control unit 2 and the battery unit 3 are removed in FIG. 12 (b).

An aggregate power line 61 and an aggregate signal line 62 are arranged on the back side of the convex portion of the cover member 40 along the ascending / descending direction, respectively, and are Z-bent to partition the aggregate power line 61 and the aggregate signal line 62 in the cover member 40. A partition plate 43 is provided.

By providing the partition plate 43 in this way, it is possible to prevent interference of magnetic noise between the aggregate power line 61 and the aggregate signal line 62, and it is possible to increase the rigidity of the wiring portion 6.

Further, if the control unit 2, the battery unit 3, the command unit 4, and the accessory unit 5 forming the unit can attach and detach the connectors 12 to 15 connected to the wiring unit 6, the unit mounting plate 37 or the cover member 40 can be attached. It can be removed from the housing 8 simply by removing the fastener 38 of the above, and can be relocated to a wide area such as a pit, a car 300, or the outside of a hoistway 200 for work. As a result, the aggregated power line 61 and the aggregated signal line 62, which are unrelated to the work, are not touched, and the wires are prevented from being accidentally connected or damaged, and the workability is remarkably improved.

It is placed in the body 8.

The regenerative resistor 22 is a function that consumes regenerative power when, for example, the elevator car 300 is stopped, and the amount of heat generated when the regenerative power is consumed is very large. Therefore, it is preferable to dispose of it at the end of the housing 8 at the upper part of the drive unit 1 in order to improve heat dissipation efficiency.

With such a configuration, the regenerative resistance portion 7 can be housed in the housing 8.

Embodiment 6.
FIG. 18 is a schematic configuration diagram of the printed wiring board according to the sixth embodiment. The printed wiring board 440 (first printed wiring board) shown in FIG. 18 has a connector mounted on the wiring pattern of the printed wiring board 44.

A connector 110 is mounted on the outer periphery of the printed wiring board 440 so that the insertion / removal direction is in the plane direction (X direction or Z direction), and the insertion / removal direction is in the out-of-plane direction (Y direction) inside the printed wiring board 440. The connector 111 to be attached is mounted. At least one of the connectors 111 is, for example, a master connector (hereinafter referred to as “connector 111a”) connected to the control unit 2. Further, at least one of the connectors 111 may be, for example, an inspection connector (hereinafter referred to as “connector 111b”) for sucking out data such as past operation information or environmental information of the elevator at the time of inspection. The connector 110 in FIG. 18 is the same as the connector 19 in FIG. Further, it can be said that the connector 111a is arranged on the wiring pattern of the printed wiring board 440.

First, the connector 111a will be described. The connector 111a has, for example, a plug 65 and a receptacle 66. The electric signal is taken into the connector 110 from the aggregated signal line 62 connected to at least one of the control unit 2, the command unit 4, and the incidental unit 5. The electric signal captured in the connector 110 is captured in the printed wiring board 440, and is captured in the connector 111a via the wiring pattern provided in the printed wiring board 440. The connector 111a has a configuration in which at least two or more poles, that is, at least two or more electric wires can be connected to the plug 65 side, and is connected to the wiring pattern of the printed wiring board 440. For example, the receptacle 66 is soldered to the printed wiring board 440, and the receptacle 66 and the plug 65 are in contact with each other in a removable manner.

The plug 65 is connected from one terminal of the plug 65 to another terminal by an electric wire, for example, a loop wiring (not shown in FIG. 18). That is, by connecting the plug 65 to the receptacle 66, an arbitrary pattern of the printed wiring board 440 can be short-circuited. On the other hand, by removing the plug 65 from the receptacle 66, the continuity of an arbitrary pattern of the printed wiring board 440 can be cut off. That is, the operator can turn on / off an arbitrary electric circuit via the printed wiring board 440 by inserting and removing the plug 65 and the receptacle 66 of the connector 111a. The plug 65 and the receptacle 66 do not necessarily have to be one-to-one, and a plurality of plugs 65 may be connected to one receptacle 66.

During maintenance or work, the operator must be careful not to touch the live line, that is, the energized power line 63 and signal line 64, usually accessing each unit and shutting off the breaker. You must work after ensuring safety.

However, in the present embodiment, since any electric circuit can be cut off by disconnecting the connector 111a of the printed wiring board 440, the work procedure for ensuring safety when maintaining and inspecting each unit is reduced. Can be done. Furthermore, the work procedure can be simplified by collecting the connectors to be inserted and removed for each maintenance and inspection work unit.

Next, the connector 111b will be described. The connector 111b is mainly connected to the command unit 4, the incidental unit 5, and the like, and the connector 111b sends and receives signals. The connector 111b has no plug 65 inserted in the normal state, but is arranged in the elevator control panel 100 by the receptacle 66 alone, and an operator inserts the plug 65 into the connector 111b at the time of inspection.

At the time of maintenance and inspection, the state information of the elevator control panel 100 can be easily grasped by the operator inserting the inspection connector normally used as a jig into the connector 111b by the operator. For example, a huge amount of data such as past operation information or environmental information of the elevator stored in the command unit 4 can be sucked out from the connector 111b.

Further, since the elevator control panel 100 is vertically long, it is necessary to move the car 300 up and down in order to access each unit, which increases the working time. However, by aggregating maintenance data on the printed wiring board 440 and sucking out the data by the connector 111b, the basket 300 does not move up and down, and workability can be improved.

Here, FIG. 19 is a schematic cross-sectional view of the printed wiring board according to the sixth embodiment. In FIG. 18, the connector 111 (first connector), which is a master connector, is mounted on the printed wiring board 440 and arranged independently of each other. In FIG. 19, the connector 112 (second connector) is used. ) Is mounted on the printed wiring board 441 arranged on the door portion 9 side of the housing 8 with respect to the printed wiring board 440 and the printed wiring board 440, and connects the printed wiring board 440 and the printed wiring board 441. The details will be described below.

The wiring unit 67 shown in FIG. 19 refers to, for example, a base 39 and a printed wiring board 441 (second printed wiring board) on the base 39. The elevator control panel 100 shown in FIG. 19 has a structure in which at least one connector 112 is disconnected by removing the wiring unit 67. The wiring unit 67 does not have to be a single unit, and the printed wiring board 441 may be integrated with, for example, a command unit 4 or an accessory unit 5. Further, it may be arranged side by side in the ascending / descending direction of the elevator control panel 100 together with the control unit 2 and the like, or may be arranged between the control unit 2 and the like and the wiring unit 6.

A plug 65 is mounted on the printed wiring board 441 so as to correspond to the receptacle 66 mounted on the printed wiring board 440. A hole (not shown in FIG. 19) is formed in the base 39 so that the plug 65 of the printed wiring board 441 can be connected to the receptacle 66. The plug 65 may be arranged on the printed wiring board 440, and the receptacle 66 may be arranged on the printed wiring board 441. Further, speaking of the connector 112 by combining the receptacle 66 mounted on the printed wiring board 440 and the plug 65 mounted on the printed wiring board 441, the connector 112 is arranged on the wiring pattern of the printed wiring board 440 and the printed wiring board 441. It can be said that the printed wiring board 440 and the printed wiring board 441 are connected by the connector 112.

When the connector 112 is mounted on the printed wiring board 441, the degree of freedom in design is higher than when the connectors 111 are arranged independently. Further, by integrating the circuit function configured by the command unit 4 or the incidental unit 5 with the printed wiring board 441, it is possible to make a simple configuration for signal transmission between the command unit 4 or the incidental unit 5 and another unit.

Further, since the wiring unit 67 can be removed and at the same time the arbitrary electric circuit of the elevator control panel 100 can be cut off, it becomes easy to ensure safety when replacing each unit of the elevator control panel 100.

Further, the above-mentioned configuration can facilitate the design change. When the signal line 64 cannot be processed by the printed wiring board 440 alone due to the expansion of optional functions in the elevator control panel 100, the wiring unit 67 can be added without changing the design of the printed wiring board 440. The number of signals that can be processed can be increased.

In the present disclosure, each embodiment can be freely combined, and each embodiment can be appropriately modified or omitted within the scope of the invention.
