This invention relates to an elevator apparatus.

In a conventional elevator device, particularly an elevator that performs group management control for managing the operation of a plurality of elevators as a group, the number of units assigned in consideration of operating efficiency is assigned to the destination floor registered by the user. Is called. Then, the user who registered the destination floor gets on the designated (assigned) elevator. In this case, if the distance from the destination floor registration device where the user performs the destination floor registration operation to the designated unit is far, the unit will depart before the user arrives at the designated unit entrance. May end up.

Therefore, in an elevator apparatus equipped with a destination floor reservation device that registers a destination floor together with personal information before boarding the elevator, the user who has registered the destination floor from the destination floor reservation device inputs personal information at the landing In the past, while there was a person who did not enter personal information from the input device among the users who registered the personal information from the destination floor reservation device, the elevator was kept open at the landing It is known (see, for example, Patent Document 1).

In addition, among call registration devices installed at a landing, a device that preferentially assigns a landing call to a machine with a short distance from the call registration device where the call registration operation has been performed is also known (for example, Patent Documents). 2).

Furthermore, elevator devices that perform automatic registration of calls and allocation of units to calls by estimating the travel time of users to the landing are also known in the past (see, for example, Patent Documents 3 to 5). Among these, what is described in Patent Document 5 is a movement from a position where a user registers a destination floor using a portable terminal carried by a user and the user operates the portable terminal to input a destination floor. Time is calculated.

In connection with the above, as a means of detecting the moving speed of the user at the elevator hall, a camera for photographing the hall is installed, and the moving direction and moving speed of the moving object are based on the moving locus of the moving object on the camera image. Is known in the past to determine whether or not the moving object is disabled (see, for example, Patent Document 6).
