DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENT
An information recording apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Referring to Fig. 1, reference symbol T-1 denotes a reel-to-reel cassette tape (to be simply referred to as a tapeT-l ). The tape T-1 may comprise an audio or video cassette. Reference symbol T-2 denotes an endless tape (to be referred to as a tape T-2 hereinafter) which may be an audio orvideo cassette. The recording time of the endless tape from the start point to the end point thereof is about 20 to 60 seconds. The tapeT-2 is driven together with the tape T-1 to start recording. When a userwishesto keep a portion of a program for later use or for repeated viewing while a
TV program is being recorded in the main tapeT-1 and the user is watching the original broadcast, only the tape T-2 is set in the PLAY mode to check the recorded content or is ejected for later use.Subsequently, anotherendlesstape is inserted in the recording apparatus to continue monitoring without interrupting or interfering with recording ofthe main tape T-1.
Forthis purpose, the information recording apparatus of this embodiment has the following system configuration.
Reference symbol VTR-1 denotes a commercially available video tape recorderfor driving the reel-toreel cassette tape T-1; VTR-2, a commercially available video tape recorderfor driving the endless tape T-2. In the video tape recorders VTR-1 and VTR-2, reference numerals 3 and 6 denote light-receiving portions for receiving coded infrared rays emitted from infrared remote control units 9 and 10, respectively; 4 and 7, eject buttons for the tapesT-1 and T-2, respectively; and 5 and 8, monitor jacks for earphones (not shown), respectively. The infrared remote control units 9 and 10 are provided as accessories of the video tape recorders VTR-1 and VTR-2, respectively.Each infrared remote control unit has a known structure including channel selection buttons, a PLAY button, a
REC (recording) button, a STOP button, a REW (rewinding) button and an FF (fastforwarding) button.
Each button terminal is electrically connected by a switching transistor (not shown) in response to a signal from a central controller 11 (to be described in detail later). The central controller 11 controls the video tape recorders VTR-1 and VTR-2. In the central controller 11, reference symbol REC1 denotes a common REC button forthe video tape recorders VTR-1 and VTR-2; and reference symbols STOP1,
PLAY1, FF1 and REW1 denote STOP, PLAY, FF and
REW buttons forthe video tape recorderVTR-1, respectively. Reference symbols STOP2 and PLAY 2 denote STOP and PLAY buttonsforthe video tape recorder VTR-2. When a desired button forthe video tape recorderVTR-1 is depressed, a corresponding control signal is supplied to the infrared remote control unit 9.A corresponding button terminal in the remote control unit9 is electrically connected to emit a coded infrared ray, thereby controlling the video tape recorderVTR-1. When a desired button forthe video tape recorderVTR-2 is depressed, the video tape recorder VTR-2 controls the infrared remote control unit 10. When the useroperatesthe central controller 11 at a table, the user need not touch the video tape recorders VTR-1 and VTR-2 except for replacement of tapes and can perform effective operation. Reference numeral 12 denotes a digital switch for setting time (e.g., 60 seconds) corresponding to the recording time of the endless tapeT-2 from the start point to the end point.Although the operation ofthe digital switch 12 will be described in detail later,a timer 18 (Fig. 2) interlocked with the digital switch 12 is started when the PLAY button PLAY2 is depressed. Reference symbol Y-1 denotes a relay interlocked with the timer
18. The relayY-1 has a relay contact y1 -1 forswitching the video signal inputto a monitortelevision 17 (to be described in detail later). Preferably,a microphone 13 and a speech recognition unit 14 are arranged in the system of this embodiment In this case, when button function names ofthe central controller 11 am entered as speech data, the speech recognition unit 14 recognizesthe button function nameto control the video tape recorders VTR-1 and VTR-2 and the relay
Y-1.The user need not then depress buttons and can devote himself to the monitortelevision 17. Reference numeral 15 denotes an antenna; and 16, a receiver. An outputfrom the receiver 16 is supplied to the video tape recorders VTR-1 and VTR-2. The monitortelevision 17 monitors the television signal from the antenna 15 and the receiver 1 6through the video tape recorder VTR-1 connected through the relay contact y1 -1 whose normal position is indicated in Fig. 1.As long as the relay1 is keptenergized, the signal reproduced from the endless tape T-2 in the video tape recorderVTR-2 can be monitored through the relay contact y1 -1 located at a position opposite to the normal position.
The operation ofthe information recording appar atushavingthearrangementdescribedabovewill be described in detail hereinafter. Assumethatthe reel-to-reel tape T-1 is inserted in the video tape recorder VTR-1 and that the endless tape T-2 is inserted in the video tape recorder VTR-2 The digital switch 12 is al ready setforthe recording time of the endless tapeT-2from the start pointto the end point.
When the REC button REC1 in the central controller 11 is depressed, the switching transistor (not shown) incorporated in the central controller 11 is turned on to close the terminals of REC buttons (not shown) of the infrared remote control units 9 and 10. Coded infrared rays for recording are emitted from the infrared remote control units 9 and 10 and are received by the light-receiving portions 3 and 6 to set the video tape recorders VTR-1 and VTR-2 in the REC mode. Information (i.e.,traffic information of main roads) received throughtheantenna 1 5 and the receiver 1 6 is simultaneously recorded in the tapesT-1 andT-2 through the video tape recordersVTR-f and VTR-2.In this case, the recording period ofthetapeT-2is60 seconds, and information is updated every 60 seconds In otherwords, information can be stored for 60 seconds.
When a traffic accident occurs, and the userchecks the traffic conditions and wishes to hold the information in the endlesstapeT-2 or check again, he depresses the button STOP2. The tape recorderVTR-2 is stopped sincethe coded infrared ray from the infrared remote control unit 10 is received by the light-receiving unit 6. The eridlesstapeT-2 is stopped.
When the user depresses the eject button 7, the tape T-2isejected.Theuserinsertsa blanktapeT-2and depresses the button REC1 so that subsequent information can be recorded in the new tape T-2.
When the use wishes to check the recorded content of the tape T-2, he depresses the button PLAY2. A coded infrared ray for play mode is supplied from the infrared remote control unit 1 to the light-receiving
portion 6, and the video tape recorderVTR-2 is set in the PLAY mode. Atthe sametime, a flip-flop 19 (Fig. 2) is set in response to operation of the button PLAY2 arranged in the central controller 11. A set outputfrom the flip-flop 19 energizes the relay Y-1,and the contact y1-1 is switched to the black dot position shown in Fig.
1. The monitortelevision 17 is switched from the video tape recorder VTR-1 to the video tape recorder VTR-2.
In this case, the timer 18 is started in response to a signal from the digital switch 12 operated by the set outputf rom the flip-flop 19. The timer 18 comprises a quartz oscillator of a 1-second clock as a reference clock. Reference clocks are sequentially supplied to theclockterminal of a down cou nter 18a presetbythe digital switch 12. When a countofthe down counter 18a has reached zero, the timer 18 is stopped and reset by the digital switch 12 again. When the countofthe counter 18a has reached zero,theflip4lop 19 is reset and the relay y-1 is deenergized. The monitor television 17 is connected from the video tape recorder VTR-2 to the video tape recorderVTR-1 again.
When the tape T-2 is replaced with a blanktape or is kept unchanged and the button REC1 is depressed, the video tape recorderVTR-2 is switched to the REC mode in response to the outputfrom the infrared remote control unit 1 to the light-receiving unit 6.
Since recording of the video tape recorder VTR-1 is continuedwhilethe endless tape T-2 is being replaced with a blanktape or being played for monitoring, no information is omitted. The monitortelevision 17 is switched to thevideo tape recorderVTR-2 while the recorded content ofthe tape T-2 is being reproduced and checked. During this period, the video tape recorderVTR-1 cannot be monitored. However, an additional monitortelevision allows monitoring ofthe video tape recorder VTR-1.
As may be apparent from the above description, when the user wishes to keep a portion of a real-time television program while the program is being recorded in the main tape ofthe audio orvideotape recorder, the same content as in the main tape can be simultaneously recorded in the endless tape. The endless tape can be ejected for later use, and a blank endless tape is inserted to continue recording. The recorded endless tape can be set in the PLAY mode to check the content for 20 to 30 seconds in accordance with the maximum recording time thereof. In this case, when the user decides thatthe content ofthe endlesstape is not needed, the same endlesstape is set in the REC mode again for recording of subsequent external information simultaneously recorded in the main tape.
The present invention can be effectively used for a variety of information systemsto continuously monitortraffic on a busy road orat an intersection orto monitor events forvarious scientific purposes. For example,the user can setthe endless tape in the PLAY modeto check circumstances several tens of seconds before a traffic accident occurred by reviewing the endless tape. When the userjudgesthatthe recorded content is not important, the endless tape is setin the
REC mode again. However,when hejudgesthatthe recorded content is very important, the endless tape is ejected and used for later analysis. In this case, another endless tape is insertedforsubsequent recording without interrupting or interfering with recording ofthe main tape.
In the above embodiment, a magnetic tape is used as the recording medium. However, large-capacity random access memories (RAMs) or optical recording means (laser disks) which have been developed as recording media are available at low cost. Shortperiod recording of such solid-state memories or optical recording means has been practiced, and they can be used asthe recording mediafortheobjectiveof the present invention. In this case, the endless tape T-2 is replaced with an endless solid-state memory oran optical recording means. In oth er words, when the end address of the solid-state memory or the optical recording means is reached, the start address is accessed, and the above-mentioned audio/video recording can be performed by using the solid-state memories or optical recording means. As compared with endless tapes, no mechanical wear occurs with solid-state memories or optical recording means to obtain semi-permanent lifetime, thereby providing a great industrial advantage.This application can be made without departing from the scope ofthe present invention.
