Abstract
Abstract An automatic telephone answering and recording apparatus comprises: Answering means operating automatically in response to a telephone call signal arriving over a telephone line when the called person is absent to close the talking circuit of the telephone set, to reproduce an answering message previously recorded on a first cassette tape, and to send this message toward the caller over the telephone line; message recording means for recording on a second cassette tape an incoming message sent from the calling person over the telephone line; detecting means for detecting the fact that the second cassette tape has been paid out to its extreme end portion; and control means operating when there is no output of the detecting means to carry out normal telephone line connection and driving of the first cassette tape and operating when there is an output of the detecting means to carry out telephone line connection with a delay and, at the same time, not to carry out signal reproduction and transmission from the first cassette tape.

Claim 1
Independent Claim
294 words
An automatic telephone answering and recording apparatus comprising: a first cassette tape recorded previously with an answering message; answering means connected to a telephone line and operable automatically in response to a call arriving over the telephone line from a caller when the called person is absent for actuating reproducing means for play back of the answering message of the first cassette tape and for actuating connecting means for connecting to the line a transmitting means for sending said message through the telephone line toward the caller; a second cassette tape having a still unrecorded portion; caller's message recording means which is adapted to operate after the completion of the operation of said answering means for recording on the second cassette tape a message arriving from the caller through the telephone line; detecting means connected to said caller's message recording means for detecting the fact that the second cassette tape has been paid out to its extreme end and accordingly maintaining an output detection signal so long as said tape is paid out; answering message inhibit means connected to said detecting means and to said transmitting means, for preventing the transmitting means from sending the answering message to the caller after the connecting means is operated when the output detecting signal is maintained by said detecting means; and delay means operably connected to said connecting means and to said detecting means, for operating only when the output detection signal from said detecting means is being maintained, and adapted when a call arrives, to increase the period of time required for actuation of said connecting means over the time normally required, said answering message inhibit means preventing said answering message from being transmitted after said connecting means is actuated with delay through said delay means.

An automatic telephone answering and recording apparatus comprising: a first cassette tape recorded previously with an answering message; answering means connected to a telephone line and operable automatically in response to a call arriving over the telephone line from a caller when the called person is absent for actuating reproducing means for play back of the answering message of the first cassette tape and for actuating connecting means for connecting to the line a transmitting means for sending said message through the telephone line toward the caller; a second cassette tape having a still unrecorded portion; caller's message recording means which is adapted to operate after the completion of the operation of said answering means for recording on the second cassette tape a message arriving from the caller through the telephone line; detecting means connected to said caller's message recording means for detecting the fact that the second cassette tape has been paid out to its extreme end and accordingly maintaining an output detection signal so long as said tape is paid out; answering message inhibit means connected to said detecting means and to said transmitting means, for preventing the transmitting means from sending the answering message to the caller after the connecting means is operated when the output detecting signal is maintained by said detecting means; and delay means operably connected to said connecting means and to said detecting means, for operating only when the output detection signal from said detecting means is being maintained, and adapted when a call arrives, to increase the period of time required for actuation of said connecting means over the time normally required, said answering message inhibit means preventing said answering message from being transmitted after said connecting means is actuated with delay through said delay means.
Claim 3
Dependent Claim
64 words
An automatic telephone answering and recording apparatus as set forth in claim 1 which further comprises remote control means connected to the telephone line and operable by remote control by the owner of the apparatus, through the telephone line, to rewind said second cassette tape so as to disconnect the output signal of the detecting means and thereby to render said delay means inoperative.
Claim 4
Dependent Claim
98 words
An automatic telephone answering and recording apparatus as set forth in claim 1 in which said delay means has a charging and discharging circuit operating in accordance with the existence or nonexistence of the output of the detecting means to form circuit organizations of different charging time constants and to control the answering time from the instant of reception of a call signal to the start of activation of the apparatus so as to make the time period for actuating said connecting means longer when there is the output detecting signal than when said signal is not present.
Claim 5
Dependent Claim
148 words
An automatic telephone answering and recording apparatus as set forth in claim 1 in which said delay means comprises flip-flop circuits for a number of digits respectively connected in series and operating in response to reception of call signals to produce outputs, an AND circuit having an input connected to the output of each said flip-flop circuit and having an output connected to said connecting means so that when a first predetermined number of calling signals are received, said AND circuit activates said connecting means, and bypass means connected to said flip-flop circuits for bypassing specific output signals out of said outputs of said flip-flop circuits when said detecting means maintains said output detection signal, wherein, when said bypass means is operated, said AND circuit activates said connecting means in response to the arrival of a second predetermined number of calling signals larger than the first predetermined number.
