In Fig. 1, 11) indicates a shelf device, and (11) to (
1n) is a plurality of shelves, for example, 40 shelves.

(2) is lifting i! Ifll1 means is an elevator at 0.degree. C., and is driven up and down along the guide (3) under driving control by the elevating and lowering drive means (4). This elevator (
2) is provided with two shelves (5), (6), of which the upper shelf (5) receives tape cassettes (7) (Fig. 2) from the shelves (11) to (In); Return it to its original shelf, or, for example, store four VTRs (81 (81) to (81)
4) )), and the -t shelf (6) is V
This is a shelf for returning the tape cassette (7) received from TRt8) to one of the shelves (11) to (In).

(9), Qφ is the upper and lower shelves of elevator (1) + 51.
(This is a motor that drives actuators (not shown) for moving the 61 tape cassettes (7), respectively.

Further, (12) is a bar code (12) which is provided on the upper shelf (5) and is attached to, for example, the back of the tape cassette (7) as shown in FIG.
11) is a photodetector as a detection means for detecting. Detection signal 4 from this photodetector (12);! A/D
’ζ microcomputer (
14). (14M) and (14K) are a monitor receiver connected to the microcomputer (14) and an auxiliary controller (equipped with a keyboard) capable of being a wired or wireless remote controller.

In addition, indicators (15) such as LEDs ((15z) to (15n)) are attached to each side of the shelves (Ii) to (in), and these indicators (15) are connected to the microcomputer (14). When the barcode (11) of the tape cassette (7) stored on the shelf is correctly read, the indicator corresponding to the shelf is turned on.

The contents of the identification data based on the barcode (11) attached to the tape cassette (7) include, for example, as shown in FIG. Sending number (story number) b, title of tape recording content for 14 characters C, tape playback start time for 28 characters (hours, minutes, seconds, and frames (1/30 seconds)) d, tape playback time for 6 characters ( hours, minutes, seconds and frames) e
and a checksum g for l characters. There are various methods for barcode patterns for one character, but in this example, a 2 of 5 (2 of 5) interleave method is adopted, as shown in FIG. 4A, for example. That is, a barcode for one character is constructed from three black bars with a width of 1 and two black bars with a width of 3, and the total width of the black bars is 9. A barcode is also formed by the spacing between these bars, and another barcode for one character is formed from the three own bars with a width of 1 and the two own bars with a width of 3.

Next, we will discuss how to read barcodes. For example, consider detecting a barcode consisting of black bars.

The barcode detection signal detected by the detection means (12) in FIG. 1 becomes a sine wave whose period varies depending on the width of the black bar as shown in FIG. 4B. By shaping this waveform, an identification data signal having a time width corresponding to each black bar as shown in FIG. 4C is obtained. 1st to 5th
The pulse width of the data of the th black bar is L1+ L3+
ts, tv+to, and the pulse width of the white bar data between them is t2. t4. t6. Let it be to. Thus 1
When the barcode signal of the character is reproduced, its respective pulse width tz, ti, ts, tv.

By summing ts, dividing this by 9, and multiplying it by 1.5 to obtain a threshold value, and comparing this with the pulse width of the data corresponding to each black bar, the thickness of the black bar of the barcode can be calculated. The size of the barcode is detected, and the barcode for l characters is read. This also applies to your own bar.

First, one to a plurality (n or less) of tape cassettes (n or less) necessary for a certain unit broadcast time are placed on the shelves (11) to (in).
7) is stored using human hands.

Then, the barcodes (11) of all the tape cassettes (7) stored in each column are read and stored in the microcomputer (14). This will be explained with reference to FIG. 5. This FIG. 5 shows a microcomputer (14) for reading the code (11)
) functions are shown in blocks. The elevator (2) is provided with the above-mentioned detection means (12) and A/D converter (13), and the A/D converter (13)
The detection output of the detection means (12) is supplied to and digitized. Then, this digitized detection signal is supplied to a time width detection means (16), and the digitized detection signal is counted by the clock signal from the clock signal generator (17) with a sufficient frequency. The time width is detected. Then, the threshold calculation means (18
) Odor °ζ The above-mentioned threshold value is calculated. Then, the output of the time width detection means (16) is determined by the comparison means (
19) and threshold calculation means (18).
), and data based on the thickness of the black bar (or its own bar) is detected. The output of this comparison means (19) is supplied to the data time width size code conversion means (20), the output is further supplied to the 2-of-5 code conversion means (21), and the output is further converted into ASCII code. The data is supplied to means (22), and its output is further supplied to data generating means (23). Data creation means (
The barcode data obtained from step 23) is supplied to the main control means (24). In addition, this main control means (24
) is provided with storage means (25).

From the main control means (24), a display control means (26) that controls the display on the display (15), and an actuator control that controls an actuator (not shown) for moving the tape cassette in the upper stage of the elevator (2). Means (27
), an elevator control means (28) that controls the elevator (2) via the lift drive means (4), and a drive means (plunger) for the detection means (12) that changes the angle of the detection means (12) (34), which will be described later. ) are respectively supplied with control signals to the drive control means (29) of the detection means.

In addition, the display control means (26) is a display device (15) ((15
1) to (15n)) to load the tape cassette (
7) When the barcode (11) is reliably read during reciprocating movement on the shelf (5) above the elevator (2), the corresponding display (15) ((15z) ~
(15n) 1 is lit. The actuator control means (27) control the motor (9) which drives the actuator of the upper shelf of the elevator (2).

FIG. 6 shows that when the barcode (11) of the tape cassette (7) described above is detected by the detection means (12) back and forth, if the barcode (11) is not detected for some reason, the detection is detected. By changing the angle of the means (12), the barcode (1
1) shows the driving means of the detection means (12) that changes the detection position in the width direction, (78) is the back of the cassette case of the tape cassette (7), and (11') is the label of the barcode (11). It is attached to the back side (7a). The detection means (12) is attached to the holder (30) and is attached to the central axis (
31). A lever (32) is provided extending from the holder (30), and is pivoted clockwise by a spring (33). On the other hand, (34) indicates a plunger, and in a critical state, the plunger (34) is not energized, and the lever (32) is pulled by the spring (33) in the non-energized state of the plunger (34), so that the detection means ( 12) is at the position of the broken line. Plunger (
34) is biased by the control output of the control means (29), the actuator of the plunger (34) moves to the right in the figure, and the lever (34) moves against the elastic force of the spring (33). 32) rotates in the counterclockwise direction, and the detection means (12) comes to a position not shown by the solid line. Thus, the barcode (11
) The barcode (11) can be detected at different positions in the width direction.

Next, the functions of the computer (14) shown in FIG.
This will be explained with reference to the flowchart shown in the figure.

As shown in FIG. 1, the elevator (2) has a shelf (5) thereon in a position where tape cassettes stored in, for example, a shelf (14) of the shelf device (1) can be delivered. When the motor (9) is controlled by the control means (27) and the actuator (not shown) is driven, the tape cassette (7) (not shown) stored in the shelf (14) is moved to the elevator (2). ) to the shelf above (5).

At this time, the barcode (11) is read by the barcode detection means (12). This barcode detection means (
The detection output of 12), that is, the digitized detection output from the A/D converter (13), is supplied to the data width detection means (16) to detect the data width, and the detection output is sent to the width comparison means (19). is supplied to the threshold calculation means (
18) is compared with the threshold value calculated by °ζ. Then, the output of the width comparing means (19) is the data width code converting means (20>-2 op5 code converting means (
21), is supplied to the data creation means (23) through the ASCII code conversion means (22), and barcode data is created. Also, by driving the actuator, the tape cassette (7) is moved to the shelf (5) above the elevator (2).
At the time of returning to the ninth shelf (14), the barcode (11) is read again and the same signal processing as before is performed. Then, in the main control means (24), it is determined whether or not the barcode (11) has been read in a reciprocating manner.If it is determined that the barcode (11) has been read in a reciprocating manner, then the barcode data is read in a reciprocating manner. It is determined whether the C barcode data has been reliably read.

When it is determined that the barcode data has not been read correctly, the drive control means (29) of the detection means is controlled as shown in FIG. 6, the angle of the detection means (12) is changed, and the By transferring the tape cassette (7) from the shelf (14) to the shelf (5) above the elevator (2) and returning it to the original shelf (14), the barcode (11) is removed.
The reciprocating reading is performed in the same manner as described above at different positions in the width direction.

When it is determined that the barcode has been read as correct data, the indicator (154) of the shelf (14) where the tape cassette (7) was stored is turned on, and the elevator control drive means (4) to start the elevator (2), raise or lower the elevator (2), and stop the elevator at the next shelf. Then, the same operation as described above is performed.

If the barcode is read correctly, the content of the barcode of the tape cassette (7) is stored in the storage means (25) together with the shelf number, and the monitor receiver (14)
Displayed on the inner surface of M). By repeating this, the identification data related to the tape recording contents of all the tape cassettes (7) stored in the shelves (11) to (in) are read, and this is stored in the storage means (25) along with the shelf number. and can be displayed on the screen of the monitor receiver (14M).

Next, the means (4o) for selectively transmitting the reproduced video signals from the VTRs (Ol) to (84) in the tape cassette automatic supply selection reproduction machine M of FIG. 1 will be explained with reference to FIG. . The reproduced video signals from the VTRs (8t) to (84) are sent to the selector 19t (the microcomputer (14) in Fig. 1).
)) selected by (41) °ζ
It is separately supplied to any of the output terminals (42^) to (42D). The video signals of channels A to D from the output terminals (42^) to (42D) are switched by the switching means (with a built-in special effect generator) (43) controlled by the microcomputer (14) shown in Fig. 1. The reproduced video signal from the selected VTR is outputted to an output terminal (43') and supplied to a broadcasting device (not shown).

Next, a method of selectively transmitting reproduced video signals from a VTR will be explained. First, create a sending list. this is,
It may be created using the microcomputer (14) shown in FIG. 1, or it may be created separately. This sending list is printed on paper. This transmission list is stored in the storage means (25) of the microcomputer (14) (Fig. 1), and is continuously output to the monitor receiver (14).
M) will be displayed on the screen shown in Figure 1.

Items in the transmission list include, for example, ■ transmission number, ■ mode identification number, ■ title, and ■ tape playback start time (
(hours, minutes, seconds), ■ Tape return time (hours, minutes, seconds), ■
Tape playback cumulative time (hours, minutes, seconds), ■Tape cassette automatic supply selection and playback machine (indicated by number, etc., if there is only one unit, this item can be omitted), ■Shelf (shelf (11')
) to (1n)), ■Channel (A-D
), (li) VTR (VTR (8t)
(any of numbers 1 to 4 corresponding to (84)), etc. Note that the order of the items is arbitrary.

Item ■ ~ [phase] of the sending list, initially, for example, item ■
Fill in the columns marked with ~■ (some of the other items except ■ can be omitted) with data, and fill in the remaining columns with tape cassettes (
Fill in with the data obtained by considering the data read from the barcode (11) in 7) and the data of other items.

Among the items ■ to [phase] in the output list, the column for the initial item ■ is filled with data, and the remaining columns are filled with data read from the barcode (11) of the tape cassette (7). It is also possible to rely on the data obtained by taking into consideration the data of other items.

Between each of the above-mentioned transmission numbers, there is a blank period for playback and transmission, such as when images of objects in the studio (for example, the Anaran, performers, chart panels, etc.), live (relay) images, etc. are being broadcast. There may be cases where During this blank period, for example, write rBREAK J or rBK in the transmission number column of item ■.
, J are displayed, and the content (title) is displayed in the title column of item ■. Then, each time a blank period is inserted between transmission numbers, the channel is sequentially changed, and the VTR is also changed accordingly. Thus,
By inserting a blank period (switching period) of zero or minute time between transmission numbers, special effects such as fade-in and fade-out can be generated. Note that this blank period is also included in the cumulative tape playback time.

For example, when using this tape cassette automatic supply selection and playback machine M for broadcasting news, news shows, advertisements, etc. in a certain time period, the number of tape cassettes (7) required is one tape cassette automatic supply selection and playback. Machine M shelf (11
)~(in), use multiple tape cassette automatic supply selection playback 131M1~Mk,
Tape cassettes (7) must be distributed to each.

Next, how to sort tape cassettes (7) using the computer (14) will be explained with reference to the functional block diagram of FIG. 9 and the flowchart of FIG. 1O. In Figure 9, (44) is a tape cassette (
7) is shown as a whole. That is, the storage means (2
Data on the transmission number and blank period are successively output from 5) and supplied to the blank period position detection means (45), and the data on the transmission number immediately before the blank period is stored in the storage means (25). Then, the data on the position of the blank period stored in the storage means (25) is given to the calculation means (46) for calculating the appropriate number of tape cassettes, and the sending number is set to n (for example, 40 ) and is as close to n as possible to form a block with a sending number, that is, a block (group) of tape cassettes (7).

Then, the data of the calculation result of this calculation means (46) is
Sending number and tape cassette automatic supply selection playback machine M1-M
k to the specification means (47), the data of the specification result is stored in the storage means (25), and the data of the specification result is used to automatically select the tape cassette of item (■) on the screen of the monitor image receiving fi (14M). You can fill in the column for the supply selection regenerator.

For example, in the case of spot advertisement broadcasting, it is assumed that there are a total of 1 to 140 transmission numbers. For example, between transmission numbers 35 and 36, between 66 and 67, between 77 and 78, and between 9
It is assumed that blank periods are provided between 0 and 91 and between 112 and 113, respectively. Thus, 35 sending numbers 1 to 35.31 sending numbers 36 to 66.24 sending numbers 67 to 90.22 sending numbers 91-112.
and 28 sending numbers 113 to 140, blocks of the first to fifth sending numbers, that is, tape cassettes (
7) blocks (groups) are constructed.

In addition, as for how to use the tape cassette automatic supply selection and playback machine M, for example, two (three or more are possible) tape cassette automatic supply selection and playback machines M 1 and M 2 can be used alternately (when there are three or more, t. The tape cassettes (7) on the shelves (11) to (In) of the tape cassette automatic supply selection and playback machine that are in the idle state may be replaced.

Shelf (In) of tape cassette automatic supply selection reproducing machine M where the number of tape cassettes (7) used is 1
When the number of stages of .about.(In) is greater than n, the tape cassettes (7) can be efficiently and easily allocated to a plurality of tape cassette automatic supply selection and reproducing machines M1 to Mk.

In addition, the barcode (11) of the tape cassette (7) stored in the shelves (11) to (in) of one or more tape cassette automatic supply selection and playback machines M,
The identification data of the tape cassette (7) is stored in the storage means (2).
5), and each time the tape cassettes (7) stored in the shelves (11) to (1n) are replaced, the identification data stored in the storage means (25) is updated. As a result, the blanks in each item of the above-mentioned transmission list are filled in or corrected, and the monitor receiver (14M)
will be displayed on the screen.

In the following description, for the sake of simplicity, an example will be described in which one tape cassette automatic supply selection reproduction fiM shown in FIG. 1 is used. Next, a simple example of the above-mentioned transmission list (displayed on the screen of the monitor receiver (14M) at the time of youth broadcast) is shown.

Table 1> □ Next, the contents of Table 1 will be explained. Each time there is a blank period between transmission numbers, the channels are changed sequentially from A to B to C.
-D-A.

The VTR is switched to a different V'l'H each time the transmission number i changes, but there is no correspondence between the VTR numbers 1 to 4 and the channels A to D. However, when the channel changes, the VTR also changes. Note that although the time or time data actually includes hours, minutes, seconds, and frames, frames are omitted for simplicity.

The transmission numbers are not necessarily in numerical order, and the 'ζ numbers may be skipped or the order of the numbers may be reversed due to the insertion of transmission numbers. Playback video signals from tape cassettes with different transmission numbers belonging to different channels are simultaneously played back by different V'I''R's, and playback video signals of one channel are played back by the switching means (43) (Fig. 8). °ζ may be selectively sent. At the time of transition, the video signals of tape cassettes with adjacent transmission numbers are reproduced partially overlappingly, and may be faded in or faded out by the special effect generating device of the switching means (43).

The tape cassette automatic supply selection playback machine M in Figure 1 is a VTR.
As shown in Table 1 above, there are 4 (7) V
TR (8t) ~ (84) are all used,
One part is used as a spare VTR, and normally the remaining three VTRs are used as spare VTRs.
The spare VTR can be used when one of the remaining VTRs fails or when a transmission number is interrupted (inserted).

That is, FIG. 1 (7) VTR (8t) to (84) are as follows:
As shown in FIG. 11, it is controlled by the main control means (24) (FIG. 5) of the computer (14).

For example, if the VTR (84) is designated as a backup VTR, the VTR (84)
TR(81) to (83) are Ichikawa VTRs, and V
The TR (84) is a spare VTR as a storage means (semiconductor memory, floppy disk, etc. non-volatile storage means)
(50) (storage means (25) is also possible). Among the Ichikawa VTRs (81) to (83)+7), for example, when the VTR (83) breaks down, the control means (24)
The VTR (83) is replaced with the spare VTR (84) under the control of , and this state is stored in the storage means (50) (the storage means (25) may also be used). In addition, the transmission number interrupt (
(insertion), the spare VTR (84) temporarily or continuously becomes a "C-product VTR", and this state becomes the storage means (50).
(The storage means (25) is also stored in 1iJ). In addition, VT
Even if all of R (81) to (84) are VTRs for goods, this state is the storage means (50) (storage means (25)
) is also stored in 11J).

This storage means (50) (or storage means (25)
)), that is, the usage states of V'l'R (8t) to (84) are stored in the storage means (25) (Fig. 5), and based on this, the VTR items in the above-mentioned transmission list are stored. The field will be filled in or corrected.

In this way, even if there is a failure in some of the VTRs, it can be quickly compensated for by the spare VTRs.
There is no trace of the transmission of reproduced video signals from the VTR.

Further, when the transmission number is interrupted or added to the transmission list, that is, when the transmission list is changed, the tape cassette can be quickly played back by the VTR.

Next, a method for determining the order in which VTRs are used will be explained. Based on the above transmission list, VTR (81) ~(
84) (D) When the tape cassette (7) loaded in a certain VTR finishes playing, that tape cassette (7) is carried by the elevator (2) and placed on the shelf (11).
~(1n) are returned to their original shelves, and the tape cassettes (7) stored in the other shelves are returned to the elevator (2).
) and loaded into the VTR again.

By not repeating this, shelves (11) to (I
The tape cassettes (7) stored in the tape cassettes (7) stored in the tapes (n) and (7) are sequentially loaded into the VTRs (81) to (84) based on the transmission list and played back.

In this case, among the VTRs (8t) to (84), the earlier the reproduction start time, the higher the priority. Then, the priority order decreases in descending order of playback end time.
The order in which the VTRs are used is determined by the calculations of the computer (14). If some of the VTRs (13s) to (84) are reserved, the same determination is made for the remaining VTRs.

This will be explained with reference to the Iam block diagram in FIG. 12, the flowchart in FIG. 13, and Table 2 shown below.

<Table 2> In Figure 12, "ζ, (25^), (25B), (25
1) to (254) indicate some storage areas of the storage means (25) in FIG. 5, and these will also be referred to as storage means.

The storage means (25^) stores data on the playback start time and playback end time of the tape cassette of each sending number based on a list as shown in Table 2, for example. Storage means (251) to (254) are husband*VTRs (8t) to
(84) Store the reproduction end time of (tI numbers 1 to 4). The playback end time data read from the storage means (-251) to (254) is stored in the VTRs (8z) to (254).
84) is supplied to the reproduction start order determining means (51);
For example, as shown in Table 2, the priority order is lowered in descending order of the playback end time, and the playback start order of the VTRs (81) to (84) is stored in the storage means (25B). ] will be filled in.

If the sending number is inserted or changed, this operation is performed again.

By doing so, it is possible to take enough time to replace and load the tape cassette (7) into the VTRs (8z) to (84).

Next, regarding the auxiliary controller (14K) in Figure 1, the 14th
This will be explained with reference to the figures. (60^) to (60D) are display marks corresponding to channels A-D, (61^) to (6
10) are normal playback control operators (operation buttons) for the VTR, (62^) to (62D) corresponding to channels A-D.
) are still image playback control operators for VTR (tM work 1), (63^) to (63D) corresponding to channels A-D.
) are the control buttons (operation buttons) that return the VTR to the playback ready state, corresponding to channels A to D, and (64) are the power switch controls (slide descendants), respectively on the panel (66).
It is placed on top.

To explain the operation of this auxiliary controller (14K), when the power controller (64) is on, the controllers (61^) to (
63D) (which also serves as a display element), the control means (2) of the microcomputer (14) is activated.
4), the V of the corresponding channel is
As soon as the TR is controlled, its operator is turned on. When the operation of the controlled function for the VTR of that channel is completed, the lighting state of that operator is canceled under the control of the control means (24).

In addition, the controls (61^) to (610), (62A) to (6
2D), (63^) ~ (63D) for each channel A
-D may be used as a common operator, and a separate channel selection operator (also serving as a display element) may be provided.

Such auxiliary control! (By adopting the 14sn, the selection means (41) and the switching means (43) can control the plurality of VTRs (8z) to (84) on channel A.
-D, it becomes easy to control a plurality of VTRs.

Next, an explanation will be given of the operation of the tape cassette automatic supply selection reproduction machine M which sequentially transmits reproduced video signals from a VTR based on the above-mentioned transmission list.

Since the sending list is stored in the notation means (25) of the microcomputer (14), the elevator (2) is controlled by the microcomputer (14) accordingly, and the elevator (2) sends the shelf device +1). Tape cassettes (7) are taken out one by one from the shelves (11) to (in), transported one by one to a predetermined one of the VTRs (8z) to (84), and loaded by horizontal loading. Also, tape cassettes (7) of VTRs that have finished playing
) is removed from the VTR by horizontal unloading,
The elevator (2) returns the objects to the original shelves of a(11) to (In) or to a previously designated return-only shelf.

When the tape cassette automatic supply selection playback machine M is in 1Y operation, I PLAYJ is displayed in the playout list on the screen of the monitor receiver (14M) if the corresponding VTR is playing, and if it is in the playback preparation state. rclJI! It is displayed as tlPJ.

Also, multiple tape cassette automatic supply selection playback machines M1 to M
When using tape cassette k, when all the tape cassettes (7) on shelves (11) to (In) of the - tape cassette automatic supply selection and playback machine have been played, the shelves (11) to (In) are
manually store a new tape cassette <7), and operate the other tape cassette automatic supply selection playback machine.

While the tape cassette automatic supply selection and playback machine M is operating the tape cassette automatic supply selection according to the sending list, it may be necessary to change the sending list. This will be explained below with reference to FIG. 15 and FIG. 16 showing a flowchart thereof.

First, the tape cassette (7) is already loaded in the VTR.
The case where C1 is replaced with another tape cassette (7) will be explained. That is, VTR (8t) to (84)
It is assumed that all tape cassettes (7) are loaded. In Figure 15, (70) is a VT with low priority.
When a sending number insertion command is given to this detecting means from an input terminal (71), the VTR having the lowest priority at that time is detected. This detected data of the VTR is given to a detection means (72) that detects whether or not the VTR is playing. If it is playing, the detected data is given to the detection means (70). The VTR with the lowest priority at that time is detected again. VTR detected by the detection means (70)
If the detection means (72) detects that the playback is not in progress, the detection data is supplied to the control means (73). The control means (73) controls the lifting drive means (4),
This lowering drive means (4) drives and controls the 'ζ elevator (2), and the tape cassette (7) of the detected VTR is driven and controlled.
) is returned to one of the shelves (11) to (In), and at the same time, the tape cassette (7) with the desired delivery number is taken out from one of the shelves (11) to (In), and the detected V i"
Load R. However, when it is the detected VTR's turn to play back, the tape cassette (7) loaded in that VTR is played again.

For example, in Table 2, the tape cassette with sending number 1 (7
) (number 3) is playing, the VTR with the lowest priority is the VTR (82) in which the tape cassette (7) with output number 4 is loaded.
(No. 2). If the V'l'R (82) is not being played, the tape cassette (7) loaded in the V'l'R (82) will have the sending number 10 or the sending number 1, for example.
25 tape cassette (7). In addition, the VTR (
83) (number 3) and tape cassette with sending number 4 (7
) loaded in the VTR (82) (number 2) are playing, the VTR with the next lowest priority is the V'l loaded in the tape cassette (7) with sending number 7.
"R (83) (number 3). Therefore, this VTR (
For example, the tape cassette (7) loaded in the tape cassette (7) loaded in
) can be replaced with Note that the tape cassette (7) with delivery number 10 was previously stored in one of the shelves (11) to ('1 rr), and the delivery order has been changed, and the tape cassette (7) with delivery number 125 has been stored in advance. is the shelf (1) after the tape cassette automatic supply selection and playback machine
1) to (In) (in this case, specify the shelf and store the photodetector (12) in the elevator (2).
The barcode (11) of the tape cassette (7) is
) or stored in advance on any of the shelves (11) to (1n) as a spare.

In this way, when a sending number is inserted, the playback start time of the tape cassette (7) of the subsequent sending number is delayed by the calculation of the control means (24) of the computer (14), and the inserted The revised transmission list including the transmission number section is displayed on the monitor receiver (14M).

Note that a plurality of transmission numbers may be inserted simultaneously.

For example, in the case of 2 deflections, VTR' (8z) to (84)
It is sufficient to replace both the tape cassettes (7) loaded in the VTRs with the third and fourth priority levels with the other two tape cassettes (7).

In this way, it is possible to easily and reliably insert a desired transmission number, that is, a reproduction signal from a desired tape cassette (7) into the transmission list.

Note that it is also possible to delete part of the sending list.

Also, during the sending operation of the tape cassette automatic supply selection playback machine M, a blank period (VTR
By inserting a switching period), the channel after the blank period is inserted is changed, different VTRs are played back before and after the blank period, and fade-in, It enables the generation of special effects such as fade-out. In this case, the channel in which the blank period was inserted and the next channel are considered, and the channel after the blank period is changed to a channel different from both the channel in which the blank period was inserted and the next channel.

This will be explained below with reference to FIG. 17 showing the functional blocks of the computer (14) and FIG. 18 showing the flowchart thereof.

Reference numeral (80) is a detecting means for detecting a channel in which a blank period has been inserted, and when a blank period insertion command is given to this from an input terminal (81), a channel in which a blank period has been inserted is detected. This channel detection means (8
0), when a channel into which a blank period has been inserted is detected, the detection data is given to the channel detection means (82) for detecting the next channel, and the next channel is detected. Then, the detection data of the both channel detection means (80) and (82) is given to the channel change means (83), and the channel after the blank period of the channel into which the blank period has been inserted is changed to the both channel detection means (80) and (82). ), (82), the channel is changed to a channel other than both channels detected, and is stored in the storage means (25).

In the transmission list of Table 1 above, for example, transmission number 1
If a blank period (time is zero) is inserted between
will be changed to However, the channel with transmission number l remains A.

In this way, the overall channel order is not changed, the change in the channel order is partially stopped, and by inserting a new blank period, the already existing (-) blank period (especially zero or There is no longer any possibility that the special effect will become impossible due to the disappearance of the minute time period).

Note that blank periods can also be deleted. In that case,
The channel after the blank period is changed to be the same as channel 1111 during the blank period.

If we delete the blank period between °ζ and transmission numbers 3 and 4 in Table 1 above, the channels with transmission numbers 4 to 6 will change from B to A.
will be changed to If the blank period between transmission numbers 3 and 4 is zero or a minute time, the generation of special effects will be stopped.

Next, if the elevator (2) in the tape cassette automatic supply selection playback +ff1M breaks down, there is a risk that the barcode (11) of the tape cassette (7) cannot be read, so as shown in Fig. 19, Install an auxiliary barcode reader (manual barcode reader) (85) in the elevator (2) (it can also be installed separately).

This barcode reader (85) has a tape cassette (
7) A photodetector (
12') is detected, and a detection signal from this photodetector (12') is supplied to the above-mentioned microcomputer (14) via an A/D converter (13').

If the elevator (2) breaks down, the tape cassette (7)
on the auxiliary barcode league (85) and manually move the tape cassette (7) back and forth to detect the photodetector (12').
), that is, the identification data of the tape cassette (7), is stored in the memory P of the microcomputer (14).
It is stored in lt(25). After that, this tape cassette (7) is loaded into an empty VTR with a lower priority among the VTRs (8t) to (84), and when the playback order comes as usual, the tape cassette (7) is loaded into the empty VTR (8t) to (84). VT
Play with R.

Pre-made sending list (for example, consisting of sending numbers 1 to 35) Follow-up ζ tape cassette automatic supply selection playback machine M
The operation when the elevator (2) breaks down while the elevator (2) is in operation will be explained with reference to FIG. 20, which shows the transmission list displayed on the inside of the monitor receiver (14M). The meanings of the symbols for each item and content in FIG. 20 are as follows.

NO=Transmission number MD: Mode identification number TTL: Title STT; Tape playback start time DRT: Tape playback time ACT? Tape playback cumulative time M: Cassette feeder BN + shelf CH: Channel VT: VTR VTM: V'l''H mode p L, Y: Playing CUE: Preparing for playback As shown in FIG. 20A, the sending number 15. 16 is playing,
Assume that the elevator is stopped while transmission number 17 is in preparation for reproduction. Note that, since there is a possibility that the VTR number may change due to insertion of a transmission number, etc., VTR numbers below the transmission number that is being prepared for playback are not displayed.

As a result, the display in the shelf BN column and the display in the rows with sending numbers 18 and below disappear, and a horizontally elongated frame is displayed below the sending number (17). So, while looking at the hard copy sending list, find the tape cassette (7) with sending number 18 from the shelves (11) to (1n), hang it on the auxiliary barcode league (85), and read the barcode (11). After reading,
When loaded into an empty VTR (8z) (number l), the fields for each item except for the shelf items are filled in the frame and displayed as ``ζ'', as shown in Figure 20C. Sending number (1
8) Move to the next line. In the state shown in FIG. 20C, transmission numbers 16 and 17 are being reproduced, and transmission number 18 is in a reproduction preparation state. From then on, repeat this operation.

In this way, even if the elevator (2) is out of order, it becomes possible to manually reproduce and selectively send out the C tape cassette (7) using the VTR.

In addition to the VTR, audio tape recorders, data tape recorders, etc. can also be used as playback devices.

Further, instead of using a bar code, identification data may be written on the back of the tape cassette by magnetic recording or optical recording.

Effects of the Invention According to the present invention described above, a shelf device including a plurality of shelves;
A plurality of playback devices, a lifting and lowering means for transferring tape cassettes between the shelf device and the plurality of playback devices, a selective sending device for selectively sending out playback signals from the plurality of playback devices, and a plurality of playback devices; In a tape cassette automatic supply/selection playback device having an elevating/lowering conveyance means and a main control means for controlling a selection/sending means, if some of the plurality of playback devices is malfunctioning or an emergency playback is added to the tape cassette playback/sending list. The purpose is to propose something that can quickly deal with the insertion or addition of transmission.
