Abstract

An information service apparatus for serving one of messages stored to a caller through a telephone line, comprises: message storing unit; a table unit for storing plural tables for forming a hierarchical system for reproduction of the messages, each of the tables storing address data of a set of tablets out of the plural tables, and an address of the one of the messages, and a given code; a signal detector for detecting a data signal sent though the telephone line; and a controller response to a call for executing a first function in which the controller accesses one of the tables to determine the present scene where one of the messages is served, reads the address data of the set of the tables to next access to either of the set of the tables in accordance with the data signal by the caller, reproduces one of the messages in accordance with the read address, and detects the given code. The first function is repeatedly executed until detection of the given code and a second function that the first controller effects a given optional function in the presence of the given code. The general customer can use the optional service, such as mail box, recording, calling extension telephone in addition to the basic function of public information service.

Claims

1. An information service apparatus for serving one of a plurality of stored voice messages to a caller through a telephone line, comprising:

(a) message storing means for storing said plurality of voice messages;

(b) voice message reproducing means for reproducing one of said plurality of voice messages;

(c) table means for storing plural tables, for forming a hierarchical system, each of said plural tables including at least one of a plurality of table addresses to be accessed next, a message address of said one of said plurality of voice messages, and a selected one of a plurality of predetermined service codes;

(d) dial signal detection means for detecting a dial signal sent through the telephone line; and

(e) first control means responsive to a call from the caller for entering said hierarchical system and changing a scene in said hierarchical system in response to each detection of the dial signal by;

i) accessing one of said plural tables selected in accordance with the detected dial signal with reference to a table address of a previously accessed one of said plural tables; and

ii) reading one of said plurality of voice messages in accordance with a message address of the currently accessed one of said plural tables and supplying said read one of said plurality of voice messages to the caller through said voice message reproducing means, said first control means detecting said one of said plurality of predetermined service codes stored in said currently accessed one of said plural tables; and

(f) second control means responsive to said first control means and, in the presence of said selected one of said plurality of predetermined service codes in said currently accessed one of said plural tables, selecting one of a plurality of predetermined services in accordance with said selected one of said plurality of predetermined service codes detected by said first control means and effecting said selected one of said plurality of predetermined services.

2. An information service apparatus claimed in claim 1, wherein the dial signal includes a dual tone multi-frequency signal component and said dial signal detection means comprises a dual tone multi-frequency signal detection circuit for detecting said dual tone multi-frequency signal component.

3. An information service apparatus claimed in claim 1, wherein each of said plural tables further stores data in association with said selected one of said plurality of predetermined service codes.

4. An information service apparatus claimed in claim 3, wherein said data stored in each of said plural tables comprises an external telephone number.

5. An information service apparatus claimed in claim 1, further comprising:

(a) first guidance sending means for sending a first vocal guidance to said caller, said first vocal guidance being provided for requesting sending of said dial signal for selecting either of a mail box recording mode or a mail box reproducing mode;

(b) second guidance sending means for sending a second vocal guidance to said caller, said second vocal guidance requesting sending of a personal message of said caller through the telephone line;

(c) personal message storing means for storing a personal voice message sent from said caller in response to said sending of said second vocal guidance; and

(d) personal message reproducing means for reproducing a stored personal voice message, said second control means effecting said selected one of said plural services by said second guidance sending means, said personal message storing means, and said personal message reproducing means, wherein said personal message storing means stores said personal voice message when the detected dial signal indicates said mail box recording mode and said personal message reproducing means reproduces said stored personal voice message when the detected dial signal indicates said mail box reproducing mode.

6. An information service apparatus claimed in claim 4, further comprising calling signal generation means for generating a calling signal for calling one of a plurality of extension telephones connected to the same private branch exchange to which said information service apparatus is connected, by using said extension telephone number and said currently accessed one of said plural tables, said second control means effecting said selected one of said plurality of services by operating said calling means.

7. An information service apparatus claimed in claim 1, further comprising:

(a) guidance sending means for sending a vocal guidance to said caller, said vocal guidance requesting a further transmission of said dial signal; and

(b) calling signal generation means for generating a calling signal for calling one of a plurality of extension telephones connected to the same private branch exchange to which said information service apparatus is connected, by using said further transmitted dial signal.

8. An information service apparatus claimed in claim 1, wherein said first control means further comprises:

(a) detection means for detecting whether or not the dial signal detected by said dial signal detection means indicates a registering mode and for producing a registering mode signal responsively thereto; and

(b) third control means responsive to said registering mode signal for entering said hierarchical system and changing said scene in said hierarchical system in response to each detection of said dial signal, said third control means further having registering command detection means for detecting whether or not each said detected dial signal indicates a registering command, said third control means responsive to said registering command for renewing said one of said voice messages stored in said message storing means with reference to said address of said currently accessed one of said plural tables with a voice message sent from said caller.

9. An information service apparatus claimed in claim 8, wherein said third control means further comprises:

service code detection means for detecting whether each said detected dial signal indicates said service code, said third control means being further responsive to said detected service code for storing said service code in said currently accessed one of said plural tables.

10. An information service apparatus claimed in claim 1, wherein said first control means operates for changing the scene in said hierarchical system in response to the detected dial signals remotely generated by the caller on a remote telephone and transmitted to the apparatus on the telephone line,

thereby facilitating operation free of requirement for inputting input signals to an input terminal of the apparatus.

11. An information service apparatus claimed in claim 5, wherein said personal message storing means stores said personal voice message and said personal message reproducing means reproduces said stored personal voice message each in response to the detected dial signals remotely generated by the caller on a remote telephone and transmitted to the apparatus on the telephone line,

thereby facilitating operation free of requirement for inputting input signals to an input terminal of the apparatus.
