Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape copying apparatus for simultaneously copying the contents of a master tape onto a plurality of tapes.

Recently, the spread of microcomputers has been remarkable, and with this, various programs have been stored on magnetic tapes and sold.

Incidentally, the contents of such a magnetic tape are copied from a master tape, and generally a so-called tape copying device is used that simultaneously copies the contents of a master tape onto a plurality of magnetic tapes.

Conventionally, as shown in FIG. 1, in this type of tape copying device, a plurality of cassette tapes 3 on which the contents of the master tape 1 are copied are set in a reel-to-reel type master deck 2 having a master tape 1. Connect cassette-type slave deck 4 to 1, for example 19
The contents of master tape L recorded at 48 cm/sec are played back by master deck 2 at 38 cm/sec, and this is transferred to each cassette tape 3 on slave deck 4 at 48 cm.
By recording with /see, it is possible to copy at twice the speed of 4-sub.

By the way, in such a device, all tape operations on master deck 2 are done on the master deck 2 side.

Further, all tape operations on the slave deck 4 are performed on the slave deck 4 side, so that each tape operation is performed individually on each deck. However, since the master deck 2 (!Nislep deck 4) is usually installed a little apart, the worker must frequently go back and forth between the decks 2 and 4.

For this reason, not only does tape operation take a lot of effort, but
There was a drawback that the efficiency of such copying work was significantly inferior.

This invention was made to eliminate the above-mentioned drawbacks, and all operations including tape operations on the master deck and slave deck as well as replacement of raw tape for copying can be performed centrally on the slave deck side. It is an object of the present invention to provide a tape copying device that can simplify operations and improve the efficiency of such operations.

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 2, numeral 10 indicates a slave deck. In the same slave deck 10, 11 is an operation panel, for example, a keyboard, and this keyboard 11 is a pseudo-WIN for rewinding.
D) Key 111. It has a copy (COPY) key 112 and a stop (STOP) key 113, and these keys 1
It has a display, for example, display lamps 111a to 113a, which provide indications corresponding to operations 11 to 113.

Further, a central processing unit (hereinafter abbreviated as CPU) 13 is connected to the keyboard 11 via an interface 12. This CPU 13 stores all control programs.

On the other hand, reference numeral 14 denotes a plurality of copy units (total of 4, #1 to #4 in the illustrated example) into which the raw tape for copying (not shown) is sent, and this unit 14 is a deck in which the raw tape for copying is set. Main body 141 and unit driver 1
It has 42. And this unit driver 14
2,! : An address bus 15.degree. data bus 16 and a remote line 17 are connected between the interfaces 12 as unit buses.

Here, the unit driver 142 is specifically constructed as shown in FIG. 3. In FIG. 3, only one unit driver 142 is shown.

That is, the address bus 15 has four lines 1514.
152, 153, and 154, of which two lines 151 and 152 are connected to the selector 18, and the remaining two lines 151 and 152 are connected to the selector 18.
Book line 153, 154 Address comparator 1
9 is connected. This comparator 19 generates a comparison output with the set address 191, and is designed to wait for a remote signal to be sent to the remote line 17 before applying the comparison output to the enable terminal E of the selector 18. In addition, latches 201 to 20 are connected to the output terminal of the comparator 19.
4 strobe terminal S is connected. These latches 2
01 to 204 connect four data lines 161 to 164 of the data bus 16, and when a strobe pulse is applied to the strobe terminal S, the data of the data bus 16 is output. In this case, reel motor drive relays 211 and 212 are connected to the latch 201, and a reel motor drive output is generated to the deck body 141 through contacts 211a and 212a of these relays 211 and 212. A drive circuit 22 for a mode switching solenoid is connected to the latch 202, and the drive circuit 22 generates an output for driving the solenoid on the deck body 141 side. Furthermore, latch 20
3 is provided with a signal from the deck main body 141 representing the tape running state, for example, a signal representing the tape's constant speed, high speed run, stop state, and stopped state. Here, these signals can be generated, for example, by a photoreflector, that is, a device that has a reflective plate on the rotating reel side, shines light on a power guide that produces this reflective plate, and generates various status signals from the reflected light. It has gained. Furthermore, a display circuit 23 for displaying the status is connected to the launch 204.

Returning to FIG. 2, the interface 12 includes the control line 2.
4 is connected to a master deck 26 on which a master tape 25 is set. Here, the control i11] line 24 is the playback (PLAY) of the master deck 26. All commands t 71-y In, stop (S TOP) All command lines, rewind 1 (IDVViND) and fast forward (FASTFWJ) ) consists of lines that command. Further, a line 27 for transmitting a sensing post signal is connected between the master deck 26 and the interface 12. Here, the master tape 25 set on the master deck 26 is a tape with conductor sections 251 and 252 made of aluminum Ilq attached to the beginning and end of the copied content, respectively, as shown in FIG. The master deck 26 detects the conductive part 251 to start copying, and detects the conductive part 252 to generate a sensing point signal to end copying. It's straining.

In addition, the output of the master deck 26, that is, the master tape 2
The playback output of No. 5 is directly given to the deck main body 141 of each copy unit #1 to #4 on the slave deck 10 side via the line 28, and the raw copy tape (not shown) set on the deck main body 141t. ).

Next, its effect will be explained.

First, when the power is turned on, the program on the CP (Jl 3 side) checks whether all the copy units 14 #1 to #4 are in the stop mode.In this case, the address code to the address bus 15 is The check is performed by selecting the latch 203 of the deck body 141 and detecting the status signal of the photoreflector of the deck body 141 via the data bus 16.

Assume that all units 14 are currently in the stop mode, and in this state press the copy key 11 from the keyboard 11.
2 is operated, the key power at this time is 1 for each unit.
After confirming whether the code is valid for mode No. 4 (stop mode at this point), the address code is output to the address bus 15 and the data code to the data bus 16 according to the program on the CPUI a side. In this case, first considering the #1 copy unit 14, line 1 of the address bus 15
The address code is applied to the address code selector 18 via lines 51 and 152, and also to the address comparator 19 via other lines 153 and 154. Here, if the address code and the contents of the set address 191 match, a comparison output is applied to the enable terminal of the selector 18 after waiting for a signal to the remote line 17. Therefore, if the latch 201 is now selected by the selector 8, the data bus 16 is
The data is taken in and latched, and the reel motor drive relays 211 and 212 are energized and the contacts 211a and 212
A reel motor driving force is generated on the deck main body 141 side via a.

Next, when the latch 202 is selected in the same manner as described above, the mode switching solenoid drive circuit 22 is energized, and a solenoid drive output is generated on the deck body 141 side.

As a result, the #1 copy unit 14 is set to copy mode.

Such operations are similarly performed sequentially for copy units 14 #2 to #4, and all units 14 are set to copy mode. In this case, setting each unit 14 to the copy mode is performed at a predetermined time interval in consideration of the current capacity required for motor startup and solenoid operation in each unit 14, so that the current capacity when viewed from the power supply side is minimized. I'm trying to make it happen.

On the other hand, by operating the copy key 112 on the keyboard 11, the master deck 2iζ is reproduced (
PLAY) signal is provided. Once this is done, the remaster deck 26 is set to playback mode.

Then, the output of the master deck 26 and the playback output of the master tape 25 are applied to the deck main body 141 of each copy unit 14 via the line 28.

The data is copied onto raw copy tapes set on the deck main body 141.

In this state, #1 to #4 are set by the CPUI 3 program.
The tape end in the copy unit 14 is checked. In this case, the check is performed by selecting the latch 203 for each copy unit 14 based on the address code sent to the address bus 15 and detecting the status signal of the photoreflector of the deck body 141 via the data bus 16. As a result, a raw tape copied by each cohering unit 14 that has reached its end for some reason in the middle of being copied is detected.

Thereafter, the reproduction of the master tape 25 on the master deck 26 progresses, and when the copied contents of the tape 25 reach the end, a sensing point signal indicating the end of copying is generated by the conductive portion 252 shown in FIG.

This is sent to the slave deck 10 via line 27. Then, when the program of the CPU 13 confirms that each copy unit 14 and master deck 26 have stopped, each copy unit 14 and master deck 26 are set to rewind mode.

In this state, the deck main body 141 of each copy unit 14 rewinds the raw tape for copying, and at the same time, the tape end of each raw tape for copying is checked. In this case, the latch 203 is selected for each copy unit 14 based on the address code to the address bus 15 as described above, and the status signal of the photoreflector of the deck body 141 is transmitted via the data bus 16. The check is performed by detecting the Then, when the tape end is detected, the units 14 that have reached the tape end are sequentially set to a stop mode. On the other hand, when the master tape 25 of the master deck 26 also reaches the beginning of the copied content by rewinding, a sensing point signal is generated by the conductive section 251 shown in FIG. 4, and this signal is sent to the slave deck 10 side via the line 27. As a result, the CPU 13 also sets the master deck 26 to the stop mode. In this case, the master deck 26 is controlled until it stops exactly at the conductive portion 251 of the master tape 25, that is, at the beginning of the copy content. This completes the first copying onto the raw tape.

Next, replace the raw tape for copying in each copy unit 14 with a new one, and press the copy key 1 on the keyboard 11 again.
12, the master tape 25 will be created in the same manner as described above.
The copy contents will be copied to the copy raw tape of each copy unit 14.

If you wish to interrupt the copying operation of each unit 14 during copying, operate the stop key 113 on the keyboard 11. 14 is set to stop mode, and the copy operation is interrupted.

If you want to rewind the raw tape for copying in each copy unit 14, use the keyboard 11 to rewind -I--111.
address bus 1 to each copy unit 14.
5 and the data code of the data bus 16, each copy unit 14 is set to the rewind mode and each copy raw tape is rewound.

Therefore, with this configuration, tape operations on the master deck and slave deck can be performed using the keyboard on the slave deck, so all operations, including exchanging raw copy tapes on the slave deck, can be performed on the slave deck. It can be done intensively on the deck side,
As a result, compared to the conventional method in which workers had to frequently go back and forth between each deck, each operation can be significantly simplified, and the efficiency of such copying work can be dramatically increased.

Note that the present invention is not limited to the above-mentioned embodiments, but can be implemented with appropriate modifications within the scope without changing the gist.

For example, in the above description, each copy unit 14 is immediately set to the first copy mode by operating the copy key 112 on the keyboard 11, but by operating the copy key 112, the valley copy mode 14 is temporarily set to the rewind mode, and then the copying is performed. The copy mode may be set after confirming that the raw tape has been rewound.
