Abstract

A display apparatus for an elevator in which a message to be reported to the users of the elevator, such as the running status of the elevator, is displayed by a display unit disposed in a cage or a hall, a control is performed by a display control device so that the message to be reported may be displayed in a designated display aspect on the display unit, and the designation of the display aspect and the simulative display of a message in an aspect corresponding to the designated display aspect are carried out with a display aspect correction device, whereby the display as intended can be presented.

Claims

1. In a display apparatus for an elevator having a display unit which is disposed in a cage or hall of the elevator, display control means for displaying a message to be reported to users in a designated display aspect of the display unit, and display aspect correction means connected to the display control means for designating the display aspect, said display aspect correction means comprising simulation means for simulatively displaying a predetermined message in an aspect corresponding to the designated display aspect.

2. A display apparatus for an elevator as defined in claim 1 wherein said display aspect correction means comprises means for designating a scroll speed of the message display as the display aspect, and said simulation means scroll-displays the predetermined message at a speed corresponding to the designated scroll speed.

3. A display apparatus for an elevator as defined in claim 1 wherein said display aspect correction means comprises means to designate a flickering factor of a flickering display of the message as the display aspect, and said simulation means displays the predetermined message in correspondence with the designated flickering factor.

4. A display apparatus for an elevator as defined in claim 1 wherein said display aspect correction means comprises means to designate a flickering period of a flickering display of the message as a display aspect, and said simulation means displays the predetermined message in correspondence with the designated flickering period.

5. In a display apparatus for an elevator having a display unit which is disposed in a cage or hall of the elevator, display control means for displaying a message to be reported to users in a designated display aspect ont the display unit, and display aspect correction means connected to the display control means for designating the display aspect, said display aspect correction means comprising scroll speed alteration means for designating a scroll speed of the message display, and said display control means comprising flickering parameter-setting means for setting a parameter which is preset in correspondence with the designated scroll speed and which alters an aspect of a flickering display of the message.

6. A display apparatus for an elevator as defined in claim 5 wherein said display control means further comprises first memory means for storing a plurality of preset items of fixed display information, second memory means for storing correction display information applied from said correction means in correspondence with the fixed display information to-be-corrected among the plurality of items of fixed display information, and selection means for detecting whether the correction display information is stored in correspondence with the message to-be-displayed and operating in accordance with stored contents of said first and second memory means to read out and deliver the correction display information from said second memroy means when it is stored therein and to read out and deliver information corresponding to the message to-be-displayed from said first memory means when the correction display information is not stored in said second memory means.

7. In a display apparatus for an elevator having a display unit which is disposed in a cage or hall of the elevator, display control means for displaying a message to be reported to users in a designated display aspect on the display unit, and display aspect correction means connected to the display control means for designating the display aspect wherein a message which is displayed on said display unit contains an information element which becomes invalid with the lapse of time, said display aspect correction means including input means for correcting the information element to the latest content, and said display control means including a display inhibition means which is operated in accordance with the presence or absence of a correction input from said input means to give a command for inhibiting the display of the message containing an uncorrected information element when it is detected that the correction of the information element by said input means has not been made within a set time interval.

8. A display apparatus for an elevator as defined in claim 7 wherein said display inhibition means gives the command for inhibiting the display of the message containing the information element, upon detecting that the correction of a content of the information element has not been made before the fixed time interval lapses since the last correction of the content of the information element by said input means.

9. A display apparatus for an elevator as defined in claim 7 wherein said display inhibition means gives the command for inhibiting the display of the message containing the uncorrected information element, upon detecting the correction of a content of the information element by said input means has not been made in a predetermined time zone.
