In particular, the present invention can be applied to an automatic television signal transmission device in a television broadcasting station.

B. Summary of the Invention The present invention is a tape cassette automatic supply selection reproducing apparatus which sequentially reproduces and transmits video signals recorded on a plurality of tape cassettes based on a reproduction and transmission list, and divides the reproduction and transmission list into a plurality of recording media. By recording as different files, allowing the operator to give load instructions to multiple files and automatically loading the files to which the load instructions have been given, it is possible to prevent equipment trouble. It minimizes the damage to the replay list and simplifies the input operation for loading.

C Conventional Technology Conventionally, a tape cassette automatic supply / selection playback device (hereinafter,
There is one shown in FIG. 5 as a cart machine).

In FIG. 5, the shelf device 1 has a plurality of shelves, for example, 40 shelves.
Comprising by juxtaposed 1 ₁ to 1 ₄₀ for example in the vertical direction, the tape cassette 7 shown in FIG. 6 for each shelf 1 ₁ to 1 ₄₀ for recording a different video signal is accommodated. As a video tape recorder capable of reproducing a tape cassette 7 (VTR), for example, four VCR 8 ₁ to 8 ₄ are provided in parallel in the same vertical direction as the arrangement direction of the shelf 1 ₁ to 1 _40.

Shelving system 1 and VTR8 (8 ₁ ~8 ₄₎ adjacent both in cassette carrying device consisting of a guide 3 for guiding the elevator 2 and elevator 2 in the vertical direction is provided in the elevator 2
The tape cassette 7 is transmitted and received between the shelf device 1 and the VTR 8 via the.

Elevator 2 receives tape cassette 7 coming is transferred from the shelf 1 ₁ to 1 ₄₀ of the shelf device 1, a first rack provided for transport to VTR8 or shelving system other shelves 1 ₁ to 1 ₄₀ 1 5 and a second shelf 6 for receiving the tape cassette 7 transferred from the VTR 8 and transferring it to the shelf device 1. Each of the shelves 5 and 6 is provided with a transfer actuator (not shown) for transferring the tape cassette 7 to the shelving device 1 and the VTR 8, and an actuator motor 9
Alternatively, the tape cassette 7 is driven by controlling the tape cassette 7 or the rack device 1 or
It is designed to control transfer to the VTR8. The elevator 2 is moved up and down by an elevator drive device 4.

Therefore, when the tape cassette 7 housed in the predetermined shelf 1 _x (x = 1 to 40) is loaded into the predetermined VTR 8 _y (y = 1 to 4), the elevator drive device 4 is used to load the first shelf. opening of 5 the elevator 2 moves vertically to a position opposite to the opening of a predetermined shelf 1 _x, take out the tape cassette 7 from the shelf 1 _x. After that, the elevator 2 is moved by the elevator drive device 4 to a position where the opening on the VTR8 side of the first shelf 5 faces the opening for opening and removing the cassette of the VTR8 _y , and then the actuator motor 9 is driven to drive the tape cassette 7. VTR 8 _y
Insert into and load.

On the contrary, when the tape cassette 7 loaded in the predetermined VTR 8 _v (v = 1 to 4) is stored in the predetermined shelf 1 _w (w = 1 to 40), the elevator 2 uses the second shelf 6 After moving to the position facing VTR8 _v , the tape cassette 7 is inserted, and then the elevator 2 is moved up and down until the second shelf 6 reaches the position facing the predetermined shelf 1 _w , and after stopping at that position. The actuator is driven by the actuator motor 10 and the tape cassette 7 is stored in the shelf 1 _w .

The transfer and reproduction of such a tape cassette 7 is controlled by a control device 14 having a microcomputer configuration. The control device 14 controls the transfer and reproduction of the tape cassette 7 based on the reproduction transmission list stored in the buffer memory 15 incorporated therein.

Each tape cassette 7 is recorded with a video signal of a broadcasting unit such as a so-called commercial video signal or a video signal of one case of news, and each tape cassette 7 is reproduced and transmitted once. The playback transmission list 20 shown in FIG. 7 is formed in units (hereinafter referred to as events) in the order of event transmission. Playback list
An external memory device 18 is formed in advance and is stored in an external recording medium such as a floppy disk, and when the input device 13 is operated, the external memory device is, for example, a floppy disk drive device.
It is designed to be transferred from the buffer memory 15 to the memory.

Here, as items of the reproduction / transmission list 20, a transmission number NO with a serial number different for each event, a title TTL related to the event of the tape cassette 7, the tape cassette 7 are reproduced, and transmission is started as an output signal of the cart machine. Playback transmission start time (time when broadcasting is started by the next-stage broadcasting device) STT, playback transmission time (broadcasting time) DUR for outputting a reproduction signal from the tape cassette 7, integrated time ACT for transmitting an output signal, V loading number BN of the shelf 1 ₁ to 1 ₄₀ for accommodating the tape cassette 7, the tape cassette 7
There are numbers VT etc. of TR8 ₁ to 8 ₄ . The sending number NO indicates the normal sending order, but it may not always be the order. In addition, "BK" in the transmission number NO broadcasts the video signal from the television camera device or another cart machine,
It represents a blank period during which the cart machine stops the reproduction and transmission operation.

The control unit 14 based on the play-out list 20 is taken out from the shelf 1 ₁ to 1 ₄₀ in accordance with the order of reproducing the tape cassette 7 to a rack 5 of the elevator 2, this time, the optical sensor 12 provided on the shelf 5 tape cassette taken out on the basis of the bar code 11 attached to the rear representing various data related to the tape recording contents of the tape cassette 7 so that loaded in the VCR 8 ₁ to 8 ₄ to confirm that this is the predetermined, play-out start At time as is, playing the ends return the tape cassette 7 in VCR 8 ₁ to 8 ₄ its shelf 1 ₁ to 1 ₄₀ and discharged from a play-out list stored in the same time the buffer memory 15, and a display device 16 Playback transmission list displayed above
It is designed to remove that item from 20.

Incidentally, in order to visually check the play-out step to the operator, displays a play-out list 20 on the display device 16, The display device 17 _{1-17 40} corresponding to the shelf 1 ₁ to 1 ₄₀ tape cassette 7 has been removed Is lit.

VTR8 ₁ to 8 ₄ are always loaded with 3 to 4 tape cassettes 7 to be reproduced. When the tape cassette 7 that has been reproduced is ejected, a new tape according to the reproduction and transmission order of the events is recorded. The cassette 7 is immediately loaded, and the VTRs 8 ₁ to 8 ₄ are always controlled to be in a regenerating or regenerating standby state.

In this way, the control device 14 based on the replay list 20
Under the control of, the event from any of the VTRs 8 ₁ to 8 ₄ is output as an output video signal, which is output from another cart machine or directly from the television camera device by the switcher in the next stage. The video signal is selectively switched or added with a special effect to be given to the broadcasting device and broadcast.

Thus, the events from the tape cassette 7 are broadcast in a predetermined order for a predetermined period.

D. Problems to be Solved by the Invention By the way, in practice, the control device 14 is commonly used by a plurality of cart machines, and controls the reproduction and transmission of all the events transmitted in one day.

For example, the number of events related to commercial video signals is about 500 to 600 per day, and the number of events related to news video signals is about 200. As described above, when the reproduction / sending list 20 including a large number of events is loaded from the external memory device 18 into the buffer memory 15 of the control device 14 by one operation and is displayed on the display device 16, the operation for loading thereafter is performed. Becomes unnecessary.

However, increasing the load unit (hereinafter called file) in this way increases the range of damage such as data destruction when the file cannot be loaded due to device trouble, and is desirable in reducing the effect of the trouble. It is hard to say. In addition, even if the contents of a file are changed, it takes a lot of time and effort to find an event to be changed in a file that includes a large number of events.

Therefore, the event is divided into multiple playback transmission lists 20.
It is conceivable to load the divided playback transmission list 20 as a file.

However, in this way, once all the events of one file have been played back and sent, an input operation for loading the next file is required, and the operator must operate each time, which lacks workability. Becomes There is also the risk of forgetting to load it, and the broadcasting may be interrupted.

The present invention has been made in consideration of the above contradictory problems, and provides a tape cassette automatic supply / selection reproducing device capable of improving safety against troubles in loading operation and surely transmitting events continuously. Is what you are trying to do.

In the present invention for solving means above problems to solve E problem, the shelf 1 ₁ to 1 ₄₀ of a plurality of stages in which the tape cassette 7 that record different video No. is housed respectively in the tape cassette 7 Multiple videotape recorders for playing recorded video signals 8 ₁
~ 8 ₄ and each shelf 1 ₁ to 1 ₄₀ and each video tape recorder 8 ₁ to 8
Cassette transport means (2, 3) for sending and receiving the tape cassette 7 between ₄ and each item related to each event of the broadcasting unit are divided into a plurality of different reproductions for each transmission time zone based on the transmission start time STT of each event. Based on a recording medium recorded as a transmission list file and a load command from the input means 13, a reproduction transmission list file designated from the reproduction transmission list files recorded on the recording medium is loaded into the buffer memory 15 having a built-in reproduction transmission list file. , by controlling the driving of the respective video tape recorder 8 _{1-8 4} and cassette transport means (2, 3) on the basis of the play-out list file loaded shelves corresponding predetermined tape cassette 7
It is taken out from 1 ₁ to 1 _{40 at a} predetermined timing and loaded into a predetermined video tape recorder 8 ₁ to 8 ₄ via a cassette carrying means (2, 3), and from the reproduction transmission start time STT of the reproduction transmission list file in advance. after the video signal by the set play-out time DUR is play-out, erasing the matters related to the event from the play-out file file causes return the tape cassette 7 to the original rack 1 ₁ to 1 ₄₀ are repeated sequentially such operation The control means 14 is provided, and when the load command is given to a plurality of reproduction / sending list files, the control means 14 and the empty memory capacity of the buffer memory 15 and the next unloaded data recorded in the recording medium are loaded. The capacity of the reproduction and transmission list file to be reproduced is compared, and when the empty memory capacity becomes larger, it is loaded into the buffer memory 15.

F action Each item related to each event is recorded on the recording medium as a plurality of different files that are divided for each sending time zone based on the sending start time STT of each event. The unit of damage can be set for each file, and the range of damage can be reduced.

However, in this way, each file is controlled by the control means 14
The input operation for loading it into the buffer memory 15 becomes complicated.

Therefore, it is possible to specify (declare) multiple files as files to be loaded by one input operation of the operator, and automatically when the free memory capacity of the buffer memory 15 becomes the capacity to load the next file. The next unloaded file specified in is loaded.

G Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

In the case of this embodiment, the reproduction / transmission list 20 is divided for each transmission time zone based on, for example, the reproduction / transmission start time STT, and the divided reproduction / transmission list 20 is used as a recording medium having a file having different file names. It is supposed to be stored in the disk in advance. For example, the playback transmission list of the event having the playback transmission start time STT between 6:00 am and 7:00 am is stored in the file with the file name "AAA", and the playback transmission start time ST is set between 7:00 am and 8:00 am
The file name "BBB" is the playback list of events with T.
The file with the file name "RRR" is stored with the reproduction and transmission list of the event having the reproduction and transmission start time STT between 11:00 pm and 12:00 pm.

Further, in the case of this embodiment, the load command for a plurality of files can be designated (declared) by one input operation. The input device 13 is, as one of the function keys for the display device 16, an external memory device 18 including a floppy disk drive device equipped with a floppy disk 18
From the file memory 15 and a "LOAD FILE" key which provides an input command to cause the display device 16 to display the playout list for that file. In addition, when the "LOAD FILE" key is pressed, a subsidiary function key for the display device 16 appears, and a different function key is used as one of the subsidiary function keys. There is a "LINK" key that gives a command to join. In addition, the input device 13
Is provided with an "ENTER" key which indicates the end of the input operation for selecting one operation mode and gives an execution command.

When the operator wants to load multiple files (for example, files “AAA”, “BBB”, “CCC”) sequentially with one input operation, “LOAD FILE” key → “LI”
After pressing the "NK" key, input the file names in order, and then press the "ENTER" key. If one file is to be loaded by one input operation, the "LOAD FILE" key is pressed, the file name is input, and then the "ENTER" key is input.

In this way, when the operator presses the "ENTER" key, the controller 14 starts the program of the designated operation mode of the file to be loaded shown in FIG. 1 at step SP1. Then, the process proceeds to the next step SP2, and it is determined whether or not there is an input command of a file to be loaded.

When a negative result is obtained in step SP2, the process proceeds to step SP3 to end the program and proceed to another program. On the other hand, if an affirmative result is obtained at step SP2, the control unit 14 proceeds to the next step SP4 and judges whether or not the inputted file name is correct.

For example, if a negative result is obtained in step SP4 by inputting a file name including a character that is prohibited from being used in the file name, the process moves to step SP5 and an error message is displayed on the display device 16. If a positive result is obtained in step SP4 due to correct input,
Go to the next step SP6, judge whether the command to connect the files input this time is the same as the previous input command, and if a positive result is obtained, there is no need to change the contents.
Move to 3 and terminate the program.

On the other hand, if a positive result is obtained in step SP6, the control device 14 moves to the next step SP7 and determines whether or not the file name input for the first time this time is a file included in the file name list, and a negative result is obtained. Once obtained, step SP5 described above
Then, the program is terminated after displaying an error on the display device 16. On the other hand, when a positive result is obtained in step SP7, the process moves to step SP8, and it is determined whether or not there is a file that has not been given an input command this time, that is, a file to be canceled, which has already been loaded.

If a positive result is obtained at step SP8, the control unit 14 proceeds to step SP9 to erase the file to be canceled from the buffer memory 15 and then proceeds to step SP10.
Then, a new file designation to be loaded is set, and the file name is displayed in the upper left corner of the display surface DES on the display device 16 as shown in FIGS. 3 (A) and 3 (B) to display the program. finish. On the other hand, if a negative result is obtained in step SP8, the controller 14 immediately proceeds to step SP8.
Move to step 10, set a new file to be loaded, display the file name and exit the program.

Here, steps SP6 and SP8 in this program
In the judgment step of, the unique judgment result is always obtained in the first input operation. That is, a positive result is obtained at step SP6, and a negative result is obtained at step SP8.

For example, when the correct files “AAA”, “BBB”, and “CCC” are input in this order in the first input operation, the display surface DES of the display device 16 is displayed as shown in FIG. 3 (A).
"AAA, BBB, CCC" is displayed in the upper left corner of, and "AAA", "BBB", "CCC" are specified as files to be loaded.

Also, for example, in the previous input operation, the file "AAA",
"BBB" and "CCC" are entered, and the file "AAA",
The correct files "AAA", "CCC", "DDD" are now being loaded when "BBB" is loaded in the buffer memory 15.
Is input, a positive result is obtained in step SP8, and the file “BBB” is stored in the buffer memory 15 in step SP9.
Then, in step SP10, "AAA, CC" is displayed in the upper left corner of the display surface DES of the display device 16 as shown in FIG. 3 (B).
"C, DDD" is displayed and "AA" is displayed as the file to be loaded.
"A", "CCC" and "DDD" are specified.

Furthermore, in the case of this embodiment, as the capacity of the buffer memory 15, for example, a capacity capable of storing the playback transmission list 20 having 315 events is selected, and the maximum number of events that each fiber can have is limited to 300. ing. This is because, for example, if many events can be stored, it will be greatly affected by the occurrence of a trouble in the device, and the safety will be lowered.

However, in this way, even if a plurality of files are specified by one input operation, all the specified files cannot be loaded into the buffer memory 15, and only a part of the specified files are loaded. .

Therefore, the control device 14 distinguishes between the loaded file and the unloaded file and displays them. Therefore, when the newly input file is set and displayed in step SP10 described above, FIG. ), The files “AAA” and “BBB”, and the file “AA” in FIG. 3 (B).
As shown for "A", it is highlighted in reverse (white) REV.

An automatic load operation of loading a file which has been designated to be automatically loaded and which has not been loaded is executed according to the processing procedure shown in FIG.

That is, after the program is started in step SP20, the process proceeds to the next step SP21, and the control device 14 determines whether or not there is a file designated to be loaded.
For example, a negative result is obtained when all the specified files are already loaded. If a negative result is obtained in step SP21, the program proceeds to step SP22 to end the program. On the other hand, if an affirmative result is obtained, the process proceeds to the next step SP23.

This step SP23 is a step for judging whether or not the buffer memory 15 has an empty memory capacity for loading the next file. The step SP23 compares the number of events corresponding to the empty memory capacity of the buffer memory 15 with the number of events of the next file. Is done.

As a result, if there is no empty memory capacity that can be loaded and a negative result is obtained, the operation proceeds to step SP22 described above and the program is terminated, and if there is an affirmative result because there is empty memory capacity, it proceeds to the next step SP24. The next file is loaded into the buffer memory 15, and then the process proceeds to step SP25 to invert the corresponding file at the upper left corner of the display surface DES of the display device 16, and then the program ends at step SP22.

For example, the files that should be loaded are “XXX” with 50 events and “YYY” with 40 events.
Then, when the file “ZZZ” having 100 events is input, all the files “XXZ” are displayed as shown in FIG. 4 (A) by executing the processing procedure shown in FIG. 2 at this time.
"X", "YYY", and "ZZZ" are immediately loaded into the buffer memory 15, and all the file names are highlighted on the display device 16.

Also, the files that should be loaded are "PPP", which has 300 events, and "QQQ", which has 250 events.
When the file "RRR" with 300 events is input, only the file "PPP" has no capacity to store the file as shown in Fig. 4 (B1) at the time of this input, and only the file "PPP" is the buffer memory. In the display of the file name in the upper left corner of the display surface DES of the display device 16, only the file name “PPP” is displayed in white.

Playback transmission operation of each event progresses, the event that finished the playback transmission operation is deleted from the buffer memory,
Eventually, when the number of events in the empty memory capacity reaches 250, a positive result is obtained in step SP23, and the result is shown in FIG. 4 (B2).
As shown in, the file “QQQ” is loaded in the memory area of the empty memory capacity, and at this time, the files “PPP” and “QQQ” are displayed in white in the file name display.

In the same way, the playback transmission operation proceeds, and the file "QQQ"
When only 15 events remain, and the free memory capacity reaches 300 events, the file “RRR” is loaded as shown in FIG. 4 (B3). At this time, since "PPP" has already ended, the file names "QQQ" and "RRR" are displayed in white.

According to the above-described embodiment, the capacity of the buffer memory 15 is selected to be small and the number of events in each file is set to 30 at maximum.
Since it is limited to 0 events, it is possible to stop the adverse effect of data destruction etc. due to device trouble within a small range,
The safety can be improved. Further, since a plurality of files to be loaded can be designated by one input operation and the designated files are automatically loaded, the burden on the operator can be reduced and the operability can be improved. .

It should be noted that, in the above, when a plurality of files are specified by one input operation, after the "LOAD FILE" key and the "LINK" key are pressed, the file names are continuously input. The file names may be continuously input immediately after pressing the "LOAD FILE" key. Also,
When performing a new input operation to cancel a file that has already been loaded, press the "LOAD FILE" key and then enter the file name or change the file that has not been loaded. When performing such an input operation, the input operation may be distinguished by pressing the “LOAD FILE” key and the “LINK” key and then inputting the file name. At this time, if the file is already
If it is LINKed, the LINK status is displayed in the input section, so that you can easily change only the necessary parts. Even in this case, the same effect as described above can be obtained.

H Effect of the Invention As described above, according to the present invention, an operation of dividing each item related to each event of a broadcasting unit into a plurality of files and recording the recording medium, and loading the file from the recording medium into the buffer memory of the control unit By automatically performing the operation, it is possible to easily obtain the tape cassette automatic supply / selection reproducing apparatus with improved safety against apparatus trouble and improved operability.
