2. Description of the Related Art In general, when a lift is installed in a building or the like for a long time, the devices and devices of the lift are deteriorated with the aging, and it is necessary to replace these devices and devices. In particular, in a control panel installed in a machine room of an elevator, a coil portion of a contactor or a switch deteriorates, and a contact portion that repeats opening and closing operations often deteriorates.
And since this control panel is an important device which performs an operation control such as a car call registration signal, a floor display signal, and an electric signal such as a car departure and a stop, the above-described coil unit, With the deterioration of the contact points and the like, there is a concern that a serious situation such as a so-called canning accident in which the car stops and passengers are trapped may occur. Therefore, when a considerable number of years have passed since the installation of the elevator, the existing control panel is often replaced with a new one.

FIG. 5 is a diagram for explaining a conventional example of such a control panel replacement method. Generally, an elevator has an existing control panel 3 installed in a machine room 2 above a hoistway 1 as shown in FIG. The existing control panel 3 is connected to a car 5 in the hoistway 1 through a plurality of wires 4 and is connected to a display device 7 at the entrance of the hoistway 1 through other wires 6.
