Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information recording device suitable for recording medical information and the like.

[Summary of the invention]

The present invention relates to a tr1 information recording device, each set consisting of a plurality of recording and reproducing devices that simultaneously record information signals, or one that records the information signal and the other that reproduces the recorded information signal. Since the reproduced information signals from the recorder/reproducer of the set are switched and recorded on the recorder, a large amount of information can be recorded quickly at any time.

[Conventional technology]

As a conventional information recording/reproducing device, a magnetic recording/reproducing device (
VTR), a cassette tape selection and playback device, a magneto-optical disk recording and playback device, a write-once optical disk recording and playback device, and the like are known.

Problems to be solved by invention C) In hospitals, a large number of X-ray photographs are taken, but because of the large number of X-ray films, it is difficult to store them, and it takes time to retrieve them. was there. Also, CT (Co
Electronic images obtained by computer tomography and the like were recorded on computer tapes, but the same problem occurred in this case as the recording density was not as high as that shown above.

In view of this, the present invention seeks to propose an information recording device that can quickly record a large amount of information at any time.

[Means for solving problems]

The information recording apparatus according to the present invention includes a plurality of sets of recording and reproducing machines, each of which records an information signal simultaneously, or one of which records the information signal and the other of which reproduces the recorded information signal. Recording/reproducing machine (5), (6) i (
7), (8), and multiple sets of recording/reproducing devices (5), (6);
(7), switches 5W (SW2, SW3, SW4) for switching the reproduction information signals from (8);
The apparatus is characterized in that it includes a recorder (11) that records the reproduced information signal switched by the switch SW.

[Effect]

According to the present invention, a plurality of sets of recording/reproducing devices (5), (
6); either (7) or (8) is always on standby and can accept a request for information signal recording at any time; (6)
; The information signal recorded in either (7) or (8) is recorded on the recorder (11) in preparation for recording the next information signal.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. (1) is an input terminal for an information signal (for example, a video signal with an X-ray photograph). The video signal (color video signal or monochrome video signal) supplied to this input terminal (1) is passed through the selector switch SW to the distributor (4
), and is also supplied to a short-time memory (2) which functions as an alternative recording device when the later-described recording/reproducing device cannot meet the demand for recording. The video signal read from this memory (2) is supplied to the distributor (4) through the above-mentioned changeover switch SW1.

(5) to (8) are recording and reproducing machines (digital VTRs), with recording and reproducing machines (5) and (6) forming one set, and recording and reproducing machines (7) and (8) forming the other set. The magnetic tape is supplied to the structure (8) and recorded on each magnetic tape (cassette tape) so as to form an inclined track.

The reproduced video signals from the recording/reproducing devices (5) and (6) are switched by a switch SW2. In addition, a recording/reproducing machine (7
) and (8) are switched by switch SW3. Furthermore, these switches SW2, SW
The reproduced video signal from 3 is switched by a switch SW4, is supplied to a recording machine (digital VTR) (11), and is recorded on the magnetic tape (cassette tape) (12) so as to form an inclined track. Switch SW2~
SW4 is collectively referred to as switch SW.

(10) is a playback device (digital V
TR). In addition, (16) is a recording/reproducing machine (5) to (8).
) is an output terminal from which the reproduced video signal is output.

(9) includes the above-mentioned recording machine (11), playback machine (10) and tape cassette conveyor (e.g. elevator) (13),
This is a cassette tape selection and playback device consisting of a tape cassette shelf device (15).

(3) is a control device (including a microcomputer);
It also serves as a control device for the tape cassette selection and playback device (9) mentioned above. This control device (3) includes switches SW, ~
SW4, memory (2), recording/playback device (5) to (8),
Recording machine (11), playback machine (10) and tape force set N
Controls the IQ transmitter (13). In addition, (14) is a carrier (
13) is a guided guide rail.

In addition, the above-mentioned recording/reproducing machines (5) to (8), recording machine (11)
The playback device (10) may be a magneto-optical disk recording/playback device, a write-once optical disk recording/playback device, or the like.

Next, the operation of this information recording device will be explained.

When the video signal to be recorded is supplied to the input terminal (1),
When the recording and reproducing devices (5) and (6) are in a recordable state, the video signal is sent to the recording and reproducing device (5) through the distributor (4).
), (6) and are recorded on each magnetic tape (tape cassette) so as to form an inclined track. When you want to immediately play back the video signal recorded on this magnetic tape, one of the recording and playback operations, ! (6) is in the reproduction state, and the other recording/reproducing R (5) is still recording the video signal.

When the recording of video signals onto the magnetic tape by the recording/playback device (5), (6), or one of them reaches saturation, the video signal from the input terminal (1) is transferred to the recording/playback device (by the distributor (4)). 7) and (8) and are recorded. During that time, the video signal recorded on the magnetic tape of the recording/reproducing machine (5), (6) or one of them is reproduced, and the video signal recorded on the magnetic tape of the recording machine (11) is reproduced.
) and magnetic tape (cassette tape) (12
) is recorded. And the recorded cassette tape (
12) is stored on the shelf of the cassette tape shelf device (15) by the carrier (13).

This process is repeated to store a large number of recorded cassette tapes on the shelves of the shelf device (15).

The recorded data is attached to the back of the cassette tape using, for example, a bar code. Then, the control device (3) stores the position of the tape cassette stored on the shelf of the shelf device (15), and attempts to reproduce the recorded video signal of the cassette tape on which necessary information is recorded. At this time, the conveyor (13) plays back the cassette tape on a predetermined shelf of the shelf device (15) according to instructions from the control device (3)! Bring it to (10) and put it on automatically.
The video information recorded on the cassette tape is played back.

〔Effect of the invention〕

According to the present invention described above, it is possible to obtain an information recording device that can quickly record a large amount of information at any time.

Furthermore, when a tape cassette selection and playback device is employed as in the embodiment, storage, management, and retrieval of four tape cassettes becomes easy.
