Abstract
Abstract The invention provides an automatic telephone answering apparatus wherein a relay means is operated upon reception of an incoming call so as to form a loop circuit, and a message from among a plurality of types of messages stored in a speech synthesizer is produced and delivered to a caller in accordance with the conditions whether or not a predetermined time interval has elapsed since the incoming call was received, whether or not an external tape recorder is connected, and whether or not an incoming message recording tape has reached its end.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
219 words
An automatic telephone answering apparatus comprising: (a) relay means operated to be self-held in response to a call signal, and released by a momentary release circuit operated in response to a signal generated when a caller hangs up a receiver; (b) means responsive to an operation of said relay means for transmitting an audio signal through a telephone line to a tape recorder; (c) means for producing a signal to drive said tape recorder upon operation of said relay means; (d) means for selecting a first synthesized message from a speech synthesizer upon operation of said relay means and for delivering the first synthesized message to the caller; (e) means for disabling said momentary release circuit during a tie interval in which a message is produced from said speech synthesizer; (f) timer means operated upon operation of said relay means; (g) means for selecting a second synthesized message from said speech synthesizer when said timer means is turned off and for delivering the second synthesized message to the caller; (h) means for releasing said relay means by detecting a time-off signal from said timer means and an end of delivery of the second synthesized speech message from said speech synthesizer; and (i) means controlled by self-holding operation of said relay means for applying an operating current to means (b)-(h).
Claim 2
Dependent Claim
219 words
An automatic telephone answering apparatus comprising: (a) relay means operated to be self-held in response to a call signal, and released by a momentary release circuit operated in response to a signal generated when a caller hangs up a receiver; (b) means responsive to an operation of said relay means for transmitting an audio signal through a telephone line to a tape recorder; (c) means for producing a signal to drive said tape recorder upon operation of said relay means; (d) means for selecting a first synthesized message from a speech synthesizer upon operation of said relay means and for delivering the first synthesized message to the caller; (e) means for disabling said momentary release circuit during a tie interval in which a message is produced from said speech synthesizer; (f) timer means operated upon operation of said relay means; (g) means for selecting a second synthesized message from said speech synthesizer when said timer means is turned off and for delivering the second synthesized message to the caller; (h) means for releasing said relay means by detecting a time-off signal from said timer means and an end of delivery of the second synthesized speech message from said speech synthesizer; and (i) means controlled by self-holding operation of said relay means for applying an operating current to means (b)-(h).
Claim 3
Dependent Claim
70 words
An apparatus according to claim 1, wherein said tape recorder has a recording tape end detecting means, said timer means is forcibly turned turned off by a switching circuit which is operated in response to a tape end detection signal from said detecting means to determine whether or not recording can be performed, and said relay means is released after the second synthesized message from said speech synthesizer is produced.
Claim 4
Dependent Claim
42 words
An apparatus according to claim 2, wherein said switching circuit serves to release said relay means after only a third synthesized message is produced from said speech synthesizer upon reception of subsequent calls after the recording tape has reached an end thereof.
Claim 5
Dependent Claim
52 words
An apparatus according to claim 2, wherein said switching circuit serves to select only the third synthesized message from said speech synthesizer when said tape recorder is not connected to said automatic telephone answering apparatus, to deliver only the third synthesized message to all incoming calls, and to release said relay means.
