     FIG. 2 shows a second embodiment of the present invention. In this embodiment, numeral keys 37 are provided on the console 33. These keys 37 may be operated for selecting various video disc information in the video disc library 7. As an example, by operating the numeral key labeled &#34;1&#34; in FIG. 2, hotel information is displayed. By operating numeral key labeled &#34;2&#34;, information of motion pictures is displayed. In this way, a variety of information accommodated in various video discs is to be selected for display. 
     Reference numeral 43 designates a facsimile set connected to the connection terminal 25 of the telephone circuit control section 20. Reference numeral 44 designates a record sheet outlet of the facsimile set 43. 
     The operation will now be described. 
     Video discs on which information of predetermined hotels is stored are provided in the video disc library 7 in the display/memory control section 5. When a power source for the apparatus provided in the console 33 is turned on, a variety of information is successively displayed on the display section 11, usually with a constant interval time (e.g., 10 seconds). At this time, only an outline, and not the details, of information is displayed on the display section 11. Of the successively displayed information, a desired item of information is selected by operating the numeral keys 37. For instance, by operating numeral key &#34;1&#34; in FIG. 2 hotel information is selected. By operating numeral key &#34;2&#34; information of motion picture theaters is selected. After the desired item of information is selected, the search switch 13 is operated. As a result, display information displayed on the display section 11 is fast fed, for instance at an interval of 5 seconds, to successively display the outline of hotels. When informatin of a suited hotel is displayed, the search key 13 is released. As a result, detailed information of that hotel (usually about three frames) are successively displayed, while at the same time commercial voice is produced from the loudspeaker 31. In this case, the last frame is displayed for a longer period, e.g., 10 seconds. 
     When the user is satisfied with the detailed information, he or she unhooks the handset 34, inserts a magnetic card (or a coin) into the card insert section 3, and depresses the call switch 14. As a result, the dial number corresponding to the displayed information is automatically searched from the dial number memory section 18, and a telephone circuit to the telephone set 36 in that hotel is set up. Before the user&#39;s speech starts, the destination hotel is informed of the location of the information display apparatus as the source of call in synthesized voice, for instance telling &#34;New York&#34; reproduced from data stored in the voice synthesis IC, for instance for a period of a couple of seconds. 
     If the user desires a detailed map, catalogue, charge table, etc. of the destination, it may be obtained from the facsimile set 43. 
     If the user does not want to make reservation, he or she may wait for 10 seconds or depress the search switch 13 once again. As a result, display of following outline information is resumed. 
     The procedure of operation as described is announced in voice to the user from the loudspeaker 31 through the voice control section 26 aside from the procedure guide described on the guide plate 35. For example, when the logic control section 1 determines that the next situation is for the search of a suited hotel, it takes out information of voice telling &#34;Keep search button depressed until your favorite hotel is displayed.&#34; from the voice memory section 27 through the address section 29. The voice information is amplified through the amplifier 30 and uttered from the loudspeaker 31 at an output timing determined by the counter section 28. 
     As has been described before, in case when one intends to select a hotel for room reservation he or she usually contacts the fronts of hotels with reference to telephone directory advertisement columns so that he or she is to contact only a couple of hotels at the most. For this reason, if a called hotel has vacant room, the room is selected for reversation in most cases. That is, even if there are more suited hotels having vacant rooms, these hotels are not utilized for usually it is impossible to contact all the hotels in the pertient area one after another. 
     This is possible according to the present invention. In other words, with the information display apparatus according to the present invention, a number of hotels are displayed in succession, and merely unhooking the handset while information of a suited hotel is on display sets up the telephone circuit to that hotel. According to the present invention, it is thus only necessary to wait until information of a suited hotel appears on display.
