Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for operating an information recording or reproducing apparatus, and more particularly to operating an operation instruction for recording or reproducing information.

[0002]

2. Description of the Related Art Conventionally, when reproducing a video tape, a cassette tape is inserted, and if the tape position at that time is a recording portion, reproduction is started from that portion, and if it is an unrecorded portion, the tape is sent to start recording. Detecting the point of entering from the recording part to the recording part) and starting playback from there. Then, when the unrecorded portion is over the predetermined time, it is detected that the recording portion has ended, and the automatic playback operation for rewinding to the beginning of the tape and the switches for playback, stop, fast forward and fast rewind are operated in real time. There is a manual operation to perform the playback operation.

Further, in manual operation, a specific recording of a plurality of block recordings on a video tape is reproduced, so that VIS
S (VHS Index Search System
m) A method using a switch and a fast-forward or fast-return switch. In addition, the monthly magazine video SALON; Publisher, Inc.
Genkosha; Titled recordings according to P112 to P113 issued in October 1992, and added the information to the table of contents.
There is a method of operating a switch such as selection and execution to start a desired recording and reproduce it.

Further, in order to record information on a video tape, an operation to search the head of an unrecorded portion with an auto blank switch and start recording with the recording switch, or a table of contents for recording is stored, and from that information, a table of contents, There is an operation to start recording by operating switches such as selection and execution.

[0005]

[Problems to be Solved by the Invention] However, in the past,
Videotapes recorded at home often have many types of recorded contents. For example, when some drama (block) recordings are included, even if the operator wants to see the third drama recording, the automatic reproduction operation starts from the drama recording at the tape insertion position. There is a drawback that the drama intended by the operator cannot be quickly reproduced. In order to solve this, it is necessary to operate a plurality of switches such as the manually operated VISS switch and the reproduction switch, or the recording title operation, and the table of contents, the selection and execution switches.

Further, in the conventional automatic reproducing operation, if the tape position at the time of inserting the video cassette is the recording portion, it cannot be seen from the head of the recording because the reproducing is performed from that position, and the title and the description are unknown. , The contents may not be exactly known. In order to solve this, it is necessary to use the above-mentioned multiple manually operated switches to start recording.

Further, as a preparatory operation for recording information on the cassette tape, an operation of auto blank search is required. When the reproduction is instructed by the reproduction switch instruction and the recording is instructed by the recording switch instruction, it is necessary to operate the stop switch as the end instruction. Further, in a case where a cassette tape is marked and the title of the recorded contents is displayed, when a tape recorded by another information recording device is used, it corresponds to the recorded VISS signal for recording and reproduction. It is necessary to title and memorize it.

Therefore, it is troublesome to search for a plurality of switches corresponding to the operation and to perform complicated operations using many operation switches. Further, there is a drawback that in order to operate it, it is necessary to thoroughly read and remember the plurality of switch functions from the instruction manual. Also, especially for people who are in a hurry to work every day, there is not enough time to read the instructions. Therefore, it takes a considerable amount of time until a plurality of switches can be operated. Therefore, there is a drawback that the operation cannot be learned easily and in a short time.

The present invention has been made by paying attention to such drawbacks, and programs each operation sequence in advance, and when the program operates and the operation requires an operator's judgment, the judgment contents of the operation are monitored. By displaying on the screen and instructing the judgment with the operation switch 7, the number of operations of the operation switch 7 and the number of operations are reduced, the operation judgment of the operator is simplified, and the time for reading the operation specifications is greatly shortened. Further, the operation can be reserved in advance so that the playback screen is not overlooked during operation. Furthermore, the previous operation is stored, a part of it can be changed, and the number of operations is further reduced.

Further, even when the tape position at the time of inserting the clawless cassette tape is a recording portion, it is automatically reproduced from the beginning of recording. Then, when the reproduction operation is denied or a recording instruction is issued, the apparatus automatically stands by at the head of the longest unrecorded portion at the time of recording, and operations such as recording preparation and recording cueing are omitted.

[0011]

According to the present invention, in order to eliminate the drawbacks of the prior art, a sequence of operation sequences for reproduction, recording, etc. is made into a program, and means for storing it is provided. It is composed of a means for performing, a means for providing a judgment instruction by providing an operation switch at a specific branch point of the operation by the program, and a means for displaying the contents of the specific branch point to the operator.

Further, it comprises means for preliminarily reserving an operation instruction at the specific branch point and means for advancing the program according to the reserved value.

Further, means for storing the contents of the previously operated specific branch point, means for changing a part of the storage of the contents,
It comprises means for advancing the program with the stored value of the change.

Further, means for detecting the presence / absence of recording of the insertion tape position of the clawless cassette tape, and means for detecting high speed rewinding, the head of recording (VISS signal) by the presence of recording of the detecting means, and reproducing from there It consists of.

Further, it comprises means for detecting a recording instruction, means for automatically detecting the longest unrecorded portion of the tape from the detection, and means for waiting at the head of the longest unrecorded portion.

[0016]

A series of operations from the start to the end are performed by a program. The program is stored in advance. When the operation that requires the operator's judgment is reached, the judgment operation is displayed,
From the judgment display, the operator turns on the operation switch and sends an operation signal if the operation is satisfactory. If you are having trouble with that operation, do not operate the operation switch within a certain time, or if you have trouble with that operation, turn on another switch and send another operation signal. Each operation is instructed by the same operation switch or two operation switches, so the operation can be simplified, and the understanding of the operation manual and the search for the operation switch can be completed in a short time.

Before starting, the contents of all the specific branch points of the operation program are displayed, the operator judges and controls the directions of all the specific branch points from the displayed values with the operation switches, and stores them. deep. At the time of operation, the operation program is activated, and when it reaches each specific branch point, it operates with the stored value, so the operator does not operate anything during that time, so mistakes in oversight of the reproduced image or when the judgment time is short It is possible to prevent the operation.

Further, since the contents of the previously operated specific branch points are stored and the stored value is slightly changed to perform a series of operations, the number of operations can be further reduced.

The cassette tape without a nail is generally recorded. Therefore, only the playback operation is performed. When the cassette tape is inserted, if the tape position is the recorded portion, the tape is rewound at high speed, the beginning of the recording where the recorded portion changes from the recorded portion to the unrecorded portion is detected, and playback is performed from that point, eliminating the need to cue the recorded portion. it can.

When the recording state is entered (when the playback state is exited)
The longest unrecorded portion of the tape is automatically detected, and the head of the longest unrecorded portion is detected, and the standby state is set there.
Then, since the recording is started from there according to the recording instruction, it is possible to omit the operation of a plurality of switches for recording preparation. Also, in the case of marking the cassette tape and displaying the title of the recorded contents, if a tape recorded by another information recording device is used, it is recorded to detect the head of the longest unrecorded part. The title switch operation corresponding to the VISS signal can be omitted.

Next, the operation will be described in more detail with reference to FIG. The figure shows a flow chart of a series of operation procedures such as reproduction, recording preparation, and recording.

When the cassette tape is first inserted, the cassette tape insertion sensor 26 sends the insertion signal to the microcomputer 1. In response to the signal, the microcomputer 1 turns on the main power supply, starts the cassette insertion / eject motor 27, takes the cassette into the apparatus, moves it to a predetermined position, and fixes it. Then, the presence or absence of the claw of the cassette is detected by the sensor 25, and when there is no claw, the reproduction operation is generally performed because the reproduction is generally performed.
21 pull out the magnetic tape 19 from the cassette,
Apply to cylinder 18. Next, the cylinder 18, the capstan motor 17, and the tape reel 16 are started for normal forward rotation. At the same time, the switches 11 and 31 are set to the reproducing side, and the reproducing circuit unit 12 is operated. The presence / absence of a sync signal of the video signal is discriminated from the reproduction circuit section 12 to detect the presence / absence of a reproduction signal. When there is no reproduction signal at the beginning, the capstan motor 17 and the tape reel 16 are switched from the normal forward rotation to the high speed forward rotation high speed feeding operation, and the operation is continued. Capstan motor 17 at the same time when the sync signal is detected
Also, the high-speed forward rotation of the tape reel 16 is returned to the normal forward rotation, and the normal reproduction operation is switched. Next, when there is a reproduction signal, the capstan motor 17 and the tape reel 15
Is switched from normal forward rotation to high-speed reverse rotation high-speed return operation, and the boundary of the presence or absence of a sync signal (the boundary between the recorded portion and the unrecorded portion of the high-speed return operation, which is called the recording head) is detected.
Alternatively, the index VISS signal from the sync signal recording / reproducing head 30 is reproduced as a reproduction reference sync 30 Hz reproduction amplifier 2
The amplified signal is input to the microcomputer 1 to detect the VISS signal at the head of the recording portion, and from that time, the high speed reverse rotation of the capstan motor 17 and the tape reel 15 is changed to a normal forward reproduction operation. Switch. From the above, when inserting the cassette tape without nails, when the position of the magnetic tape 19 is the recording portion, the head of recording is automatically detected and reproduction is started.
When the reproduction is completed, the synchronizing signal of the video signal disappears, so the presence or absence thereof is detected, the capstan motor 17 and the tape reel 15 are automatically switched to the high-speed reverse rotation, and the magnetic tape 19 is rewound at high speed (rewind), and the magnetic When the start end of the magnetic tape 19 is detected by the tape start end sensor 8, the magnetic tape running is stopped and the cassette insertion / eject motor unit 27 is activated to eject the cassette tape out of the VTR. Then, the main power supply is automatically turned off, and the reproducing operation ends.

On the other hand, when the information recording / reproducing apparatus has a nail, the reproducing or recording operation cannot be specified. Therefore, the operator makes the judgment. Therefore, the monitor 14 displays a comment "play?"
The investigator looks at the judgment comment on the monitor 14 and turns on the operation switch 7 within a predetermined time to send an operation signal if it is a reproducing operation. If the operation switch is not operated within a certain period of time, no operation signal is output, and the operation proceeds to the terminal 1 which does not reproduce. When the operation switch 7 is turned on within a certain period of time, a comment "Journal cue?" Is displayed to judge whether to cue the next recording. In response to this judgment comment, when the operation switch 7 is turned on, the magnetic tape 19 is fast-forwarded and reproduced to detect the boundary of the presence or absence of the video synchronization signal or the index VISS signal to find the head of the reproduced image at the time of sequential feeding. , From that point, start normal playback. Then, the monitor 14 displays a comment “object image?” For determining whether the image is the target image. In response to this judgment comment, when the operation switch 7 is turned on, reproduction is continued, and when the operation switch 7 is not operated for a certain period of time, the reproduction operation is stopped because it is not the target image, and the judgment comment is judged again.
Sending cue? "Return to display. Judgment as to whether to start recording in the opposite direction if the operation switch 7 is not operated for a certain period of time at that display. When the display switches to the display and the operation switch 7 is turned on, the magnetic tape is played back fast,
The playback image is cued to start playback, and if no operation is performed for a certain period, playback starts from that point. Then, a comment "Fast-forward playback?" Indicating whether the fast-forward playback is being performed is displayed, the operation switch 7 is turned on to perform the fast-forward playback, and the steady-state playback is continued unless the operation switch 7 is operated for a predetermined time. Next, when the reproduction circuit section 12 detects the absence of the video synchronization signal, the reproduction is automatically terminated and the magnetic tape 19 is stopped.
Move to display the judgment comment "Return to top of tape?"
When the operation switch 7 is turned on, the operation returns to the starting end (rewind) of the magnetic tape 19, and if the operation switch 7 is not operated for a certain period of time, the judgment comment "reproduction?" The reproducing operation is performed in the above order. Therefore,
With the operation switch 7 alone, the operation can be performed as if the fast-forward reproduction switch, the fast-return reproduction switch, the normal reproduction switch, and the like are operated.

FIG. 3 is a continuation of the terminal 1 of FIG. 2, and since the reproducing operation is not performed, the recording preparation operation is automatically started.
Then, the magnetic tape position is rewound to the starting end, high speed reproduction is performed from there, and the address data of the non-recorded portion is collected using the tape counter value. When the end of the magnetic tape is reached, the longest unrecorded portion is calculated and found by the microcomputer 1 from the collected data, the head is searched for, and the running of the magnetic tape 19 is stopped. In this way, the recording preparation operation can be automatically completed if the reproducing operation is not performed, and the same operation can be performed on the magnetic tape recorded by another recording device.
The switch operation for it can be omitted.

The detection of the longest non-recorded portion of the magnetic tape 19 is not limited to the above method. Generally, recording is performed in order from the start end of the magnetic tape 19, but by mistake, it is mistaken for the previous recording. There may be some unrecorded parts between this recording and this one. Such an unrecorded portion is several seconds at the longest in terms of time. Therefore, if there is an unrecorded portion in a longer time than this, it can be determined as the longest non-recorded portion. A flow diagram of this method is shown in FIG. 4 and will be further described.
Continuing from the terminal 1 in FIG. 3, the position of the magnetic tape 19 is detected as to whether it is a recorded portion or not by the presence or absence of the video synchronization signal.
Start timer? Then, when the timer is not activated, the timer is activated, and when the timer time reaches 100 seconds, it is determined that the portion is the longest unrecorded portion, and the operation is switched to the high speed return operation. Detecting the existence of the magnetic tape 19 from the absence of the magnetic tape and stopping the running of the magnetic tape 19 thereat
Move to. If the recorded portion is detected before the timer time reaches 100 seconds, it is determined that the recorded portion is not the longest unrecorded portion, the timer is stopped and the value is cleared, and the operation returns to the previous high speed feeding operation. On the other hand, when the position of the magnetic tape 19 is an unrecorded part, the magnetic tape 19 returns at a high speed and shifts to the "timer start?" Judgment, and thereafter, the same operation as described above waits at the head of the longest unrecorded part and shifts to the terminal 3. .

Next, returning to FIG. 3, the judgment comment "return to the beginning of the tape?" Is displayed, the operation switch 7 is turned on to eject, the power is automatically turned off, and only the recording preparation operation is completed. On the contrary, if the operation switch 7 is not operated for a certain period of time, the display shifts to the comment "record?" If the operation switch 7 is not operated for a certain time during the same display, the eject operation is started. On the contrary, when the operation switch 7 is turned on, the operation of the reproducing circuit unit 12 described above is stopped and the recording circuit unit 10 is activated. Then, the information of the video signal is recorded on the magnetic tape 19 from the magnetic heads 23 and 24 through the recording circuit unit 10. During the recording, the judgment comment "Recording completed?" Is displayed, and the display is continued until the operation switch 7 is turned on. When the switch is turned on, the recording operation is stopped, and the judgment comment "Return to the current recording head?" Is displayed. If the operation switch 7 is not operated for a certain time during the same display, the judgment comment "Eject?" Is displayed.
On the contrary, when the operation switch 7 is turned on, the high speed return operation is started, the recording head of the current recording is detected, and then the eject operation is started and the recording operation is ended.

As described above, the judgment comment of the specific branch point is displayed, and the searcher judges the display and the presence or absence of the operation of the operation switch 7 to reproduce a series of operations, prepare for recording, record, etc. I can do it.

FIG. 5 shows another embodiment of the present invention, the operation of which will be described below.

The flow charts of FIGS. 2 and 3 are displayed on the monitor 15 to show the operator a flow of a series of operations. The operator operates the operation switch 7 while seeing the judgment comment on the display, but displays the judgment comment "reproduction?" At a place different from the above-mentioned flowchart. Then, when the operation switch 7 is turned on, "1" is stored in the X = 1, n = 1 address of the RAM 3, and the judgment comment "start of cue?" Is displayed. If the operation switch 7 is not operated for a certain period of time, "0" is stored in the X = 1, n = 1 address of the RAM 3 and the operation is transferred to the terminal 4. When the operation switch 7 is turned on while the judgment comment "head search?" Is displayed, "1" is stored at the X = 2, n = 1 address of the RAM 3, and the judgment comment "target image?" Is displayed. If the operation switch 7 is not operated for a certain time, R
“0” is stored in the X = 2, n = 1 address of AM3, and the judgment comment “return cue?” Is displayed. When the operation switch 7 is turned on with the judgment comment “target image?” Displayed, “1” is stored in the X = 3, n = 1 address of the RAM 3,
The display shifts to the judgment comment "Fast forward playback?" If the operation switch 7 is not operated for a certain period of time, X =
3, "0" is stored in n = 1 and the judgment comment "heading?" Is displayed again, but 1 is added to the address count n in order to distinguish from the previous RAM3 address value of the same display. .

When the operation switch 7 is turned on when the judgment comment "Return cue?" Is displayed, X = 4, n in the RAM 3
“1” is stored in the = 1 address, and the judgment comment “target image?” Is displayed again. If the operation switch 7 is not operated for a certain period of time, "0" is stored in X = 4, n = 1 of the RAM 3 and the next judgment comment "fast forward reproduction?" Is displayed. When the operation switch 7 is turned on in the same display, X in RAM3
= 5, n = 1, "1" is stored, and the judgment comment "return to top?" Is displayed. Operation switch 7
If is not operated for a certain period of time, "0" is stored at the X = 5, n = 1 address of the RAM 3 and the judgment comment "return to top?" Is displayed. Then, when the operation switch 7 is turned on, "1" is stored in the X = 6, n = 1 address of the RAM 3 and the operation ends. If the operation switch is not operated for a certain period of time, "0" is stored at the X = 6, n = 1 address of the RAM3 and the judgment comment "reproduction?" Is displayed again, but it is distinguished from the RAM3 address value of the same display. Therefore, the operation of n + 1 → 1 of adding 1 to the address count n is performed.

FIG. 6 is a flowchart showing a part of the embodiment of the present invention shown in FIG. 5, and its operation will be described below. When the subsequent judgment comment "Eject?" Is displayed on the terminal 4 of FIG. 5 and the operation switch 7 is turned on, "1" is stored in the X = 7, n = 1 address of the RAM 3 and the operation ends there. If the operation switch 7 is not operated for a fixed time, X = 7, n = of the RAM 3
"0" is stored in one address, and in order to distinguish it from the previous RAM3 address value, n + 1 → n is processed and the judgment comment "record?" Is displayed. When the operation switch 7 is turned on in the display, "1" is stored in the X = 8, n = 1 address of the RAM 3, and the judgment comment "return to the beginning of the record?" Is displayed. If the operation switch 7 is not operated for a certain period of time, the X = 8, n = 1 address of the RAM 3
Memorize "0" and make a comment "Recording time 30 minutes? "Displays. When the operation switch 7 is turned on in the display, R is displayed.
"1" is stored at the address X = 9, n = 1 of AM3, and the judgment comment "return to the beginning of the current record?" Is displayed. RAM3 if the operation switch 7 is not operated for a certain period of time
"0" is stored in the address X = 9, n = 1, and the judgment comment "recording time 1 hour?" Is displayed. When the operation switch 7 is turned on in the display, X = 10, n = of the RAM 3
“1” is stored in one address, and the judgment comment “return to the beginning of the current record?” Is displayed. Operation switch 7
If is not operated for a certain time, "0" is stored in the X = 10, n = 1 address of the RAM 3, and the judgment comment "Recording time 1 hour?" Is displayed. When the operation switch 7 is turned on in the display, "1" is assigned to the X = 11, n = 1 address of the RAM3.
Remember the comment, "Return to the beginning of the record now?"
Is displayed. If the operation switch 7 is not operated for a certain period of time, "0" is stored in the X = 11, n = 1 address of the RAM 3, and the judgment comment "eject?" Is displayed. When the operation switch 7 is turned on in this display, "1" is stored in the X = 12, n = 1 address of the RAM 3 and the terminal No.
If the operation switch 7 is not operated for a certain period of time after shifting to step 5,
"0" is stored in the address X = 12, n = 1 of AM3,
The display shifts to the display of the judgment comment “Eject?”.
Then, the terminal 5 shifts to the process of n + 1 → 1 in FIG. 5 and shifts to the display of the judgment comment “reproduction?” Again.
By the above, the setting of the reservation operation is completed, and the reservation operation shown in FIG.
A value from the RAM 3 is input to each of the operation switches 7 in, the value "1" means turning on the operation switch 7 within a fixed time, and "0" operating the operation switch 7 within the fixed operation time. Means not to. Then, when the cassette tape is inserted, the operation reserved from the value of the RAM 3 is automatically performed. Further, in the figure, since it is a reservation operation, a new recording time is provided. Therefore, the part corresponding to that is the judgment comment "recording completed?" In FIG. From the above, the indicated value of each specific branch point is set to R
It can be stored in advance in AM3. Further, the number of the operation switch 7 described above is one, but the operation switch 7 is turned on within a fixed time by the Y switch, and the operation switch 7 is not operated within the fixed time. The operation time can be shortened, and the role of the switch is easy, so the time for reading the instruction manual can be greatly shortened.

FIG. 7 shows a program of operation of another embodiment of the present invention. In the figure, the flow charts of FIGS. 5 and 6 are displayed on the monitor 14. While watching the flow chart, the operator further sees the display of the change comment “X = 1, n = 1 address (Xn = 11) value of RAM3 address?” At the bottom of the monitor. In case of change, when the operation switch 7 is turned on, the above-mentioned FIG.
X = 1, n = 1 in the RAM3 of "0" if 0
If 0, change to 1. If the operation switch 7 is not operated for a certain period of time, the value of the RAM 3 is not changed, so the address value is not changed. Then, when the X address of the RAM3 is not the final 12, the value is incremented by 1 and the process returns to the change comment of the RAM3 address. If the X address of RAM3 is the final 12, the next n address of RAM3 (indicating the number of times the same judgment comment is repeated) is judged as the final "3?", And if it is not 3, the n address is set to 1.
Increase comment of the change of RAM3 address mentioned above "X
= 1, n = 1 Address (Xn = 11) Change value? Then, when n = 3, the changing operation is stopped and the changing operation is completed. In this way, the recorded value of the branch point of the RAM3 address of the program operated in the previous reservation operation can be changed, and the previous recording operation can be performed. Since the reservation operation record value can be partially changed only by instructing the operation switch to be turned on, the number of reservation operations can be further reduced.A judgment program in which the operation switch 7 is not operated within a fixed time is not shown, but the judgment program is not shown. When it enters, the count of the clock signal of the reference signal oscillator of the microcomputer 1 is started, and if the operation switch is instructed to be turned on before the count reaches the specified number, the count is stopped and the value is cleared. If the switch is not operated, the count reaches a specified number, and the signal that reaches the specified number is used as an instruction not to operate the operation switch 7 within a fixed time. And, although in the present embodiment reproduction operation and recording operation is composed of combined program does not change the effect of the above in program separate them.

Further, although the judgment comment is displayed on the monitor, the present invention is not limited to this, and the contents of the judgment comment may be converted into voice by a voice synthesizer and notified by a speaker.

[0036]

As described above, in the present invention, reproduction,
Programs such as recording preparation and recording are programmed in advance.
Since the contents of the specific branch point of the operation are displayed and the direction of the specific branch point can be indicated by the same operation switch (1 operation signal) or only two operation switches (2 operation signals), the operation switch The number of switches and the number of switches can be reduced, which simplifies the operation and significantly shortens the time to read the operation manual.

Before the operation of reproduction or recording, each branch point is displayed in advance, and the direction of the branch point is designated and stored. Since it operates in the direction of each branch point stored in advance during operation, you can eliminate the operation in real time, you can watch it quietly without overlooking the reproduced image or recorded image, and for a short time Since the motion judgment is not performed by, the operation error can be reduced.

Furthermore, since the direction of each previously operated branch point can be stored and a part of it can be changed to perform the desired operation, the number of operations can be further reduced.

Further, when the cassette is inserted in the read-only magnetic tape, when it is a recording portion, it automatically returns to the beginning of the recording portion and is reproduced, so that the manual operation for locating the recording portion can be omitted.

Furthermore, since the longest unrecorded portion is automatically cued when the recording is started, the number of operation instructions can be reduced and the recorded portion is not erased by mistake.
