Abstract

PURPOSE:To improve the efficiency of an operator and to perform high-precision printing operation by converting recording information on a subject into an image signal, controlling the display position, magnification, etc., of the image signal through signal processing, and generating and superposing optional attendant information upon the image signal and displaying and recording the information on a recording medium. CONSTITUTION:An image pickup element 6 as a converting means reads an identification symbol, etc., on an irradiated record 5 as an image signal through a read-in part lens system 7 and supplies them to a control circuit 8 as a control means. The control circuit 8 receives the image signal from the image pickup element 6, processes the image signal by magnification adjustment, position adjustment, etc., and sends the resulting signal to an external display device 4 for monitoring and a display device 9 for recording such as a liquid crystal display board as an image display means, thus displaying the image on the irradiated record 5. The control circuit 8 also controls various kinds of adjusting signal processing through the operation of external input switch parts 3a-3c. The display part 9 for recording receives irradiated light from a light emission part 10 and the image information displayed there is printed on an X-ray film 13 through a printing-part lens system 11 and an optical shutter 11.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an information recording device that records information from a subject onto a recording medium.

(Background of the Invention) Conventionally, as an example of this information recording device, information such as the name, medical history, etc. from the irradiation record or medical record of the subject is recorded by printing it on an X-ray film as a recording medium. There is something to do.

This was done by directly projecting onto the Xi film and printing it using a dedicated printing device.

(Problems to be Solved by the Invention) That is, the sizes of irradiation records, medical records, etc. differ from hospital to hospital, and the size, dimensions, and position of the target area for recording also vary. For this reason, it is necessary to set the printing device while adjusting it to match the irradiation records and medical records of the hospital where it will be used, and to adjust the magnification of the optical system individually to correct the size irregularities. be. Therefore, the structure has tended to become more complex and precise. Furthermore, one operator was unable to confirm whether the printed image after actual insertion was placed in the appropriate position on the xkQ film.

Furthermore, in the conventional technology, the actual printing results are also directly photographed, so the recorded characters and symbols may be irregular and difficult to see.Furthermore, in the case of colored irradiation records, the contrast of the printed image is reduced.

It becomes difficult to read and identify them.

This invention has been made in view of the above points, and makes it possible to easily perform processes such as changing the magnification of a printed image with respect to a specimen image, confirming the position of an actual image with respect to an image frame area, and recording image data with a constant contrast. The purpose is to provide an information recording device.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides an information recording apparatus that records information from a subject on a recording medium.
a conversion means for capturing an image of at least a portion of recorded information on the subject and converting it into an image signal; and for the image signal,
It includes a control means that performs signal processing such as multiplication and reduction 1 position adjustment and can output an arbitrary image signal, and an image display means that receives the image signal obtained by this control means and displays a corresponding image. It is characterized by

(Function) This invention converts recorded information on a subject into an image signal,
The display position, 5x magnification, etc. are arbitrarily controlled by signal processing of this image signal. Further, arbitrary additional information is also created, displayed superimposed on the image signal, and recorded on the recording medium.

Therefore, not only the apparatus is greatly simplified, but also the efficiency of the operator is improved, and highly accurate printing becomes possible.

(Embodiment) In the present invention, the identification symbol (information) on the radiation record as a subject is converted and read by a conversion means. The read information is temporarily stored in a storage medium, and this stored information is electrically processed by a control means. At the same time, the processed contents are displayed on an external monitoring display serving as an image display means.

This allows the operator to perform confirmation and incidental processing operations.
Therefore, according to the present invention, it is possible to record on a recording medium a recording image that is more accurate than ever and is required by the reader.

Further, the signal processing allows separation of necessary information from unnecessary noise in the intermediate density range. Furthermore, when storing the data in a storage medium, it is also possible to perform processing to store the data in a plurality of density ranges, and use the range with the least noise among them.

The signal processed in the optimum form in this way is displayed on a liquid crystal display that has the same function as an external display.A lens system is placed between this display and a recording medium such as film, and the signal is focused on the surface of the recording medium. The optical system is set to image
Information displayed on a liquid crystal display is printed onto a recording medium based on the reflection or transmission of light.

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

FIG. 1 is a schematic diagram showing an example of the basic configuration of the present invention. In FIG. It consists of an external monitoring display 4. An irradiation record 5, which is a subject, is inserted into the irradiation record insertion section 1, and identification symbols such as the name of the person to be imaged (patient) and the date of imaging are recorded in the irradiation record 5.

The image sensor 6, which is a conversion means, reads out the identification symbol etc. on the irradiation record 5 as an image signal via a reading unit lens system 7.
The signal is supplied to a control circuit 8 as a control means. Control circuit 8
receives the image signal from the image sensor 6, and the nine pairs of ``0'' image signals undergo signal processing such as magnification adjustment, position adjustment, etc. The image is sent to a recording display 9 such as a display board, and the image on the irradiation record 5 is displayed.

The control circuit 8 also includes two external input sections 3a, 3b, 3.
By the operation c, the various adjustment signal processing can be controlled. The recording display 9 receives illumination light from the light emitting section 10, and the image information displayed there is sent to the printing section lens system 11.
The image is printed onto an X-ray film 13 through an optical shutter 12.

Here, since the image information such as the identification symbol on the recording display 9 is displayed as a defect image, the light emitting unit 10 irradiates the back or the entire surface of the X-ray film 13 so that 11, and is printed and recorded at a fixed position in the same mode.

Without looking at the monitoring external display 4, the operator monitors whether the various information to be printed on the xMA film is in the optimum size and position, and operates the input switch section 3a if the information is not in the optimum size. By doing so, the magnification changing process within the control circuit 8 is controlled to obtain the optimum size. In addition, when the operator determines that the burn position of the various information is optimal by operating the input switch 3b when the position is not at the optimum position, the operator operates the input switch 3C to print the image. is fixed, the optical shutter 12 is opened, and printing onto the X-ray film 13 is performed.

Here, the control circuit 8 can create any image information other than the information recorded on the irradiation record 5 by input operation, and monitors the created image information by superimposing it on the recorded information on the irradiation record 5. The image information can be displayed on the display 4 and the display 9k for recording, or the superimposed image information can be printed on the X-ray film 13h.

The circuit also performs contrast enhancement signal processing based on the image signal from the image sensor 6. In this signal processing, the image signal from the image sensor 6 can be changed into a monochrome digital signal of a single screen and processed to obtain an easy-to-see contrast.

The various signal processings described above are manually specified by the operator while checking the burn-in contents on the monitoring external display 4, but these optimization signal processings can be performed automatically by algebraic processing. is also possible.

In the above embodiments, the image sensor 6 may be any device that converts an image into an electrical signal, such as a charge coupled device (COD) or an image pickup tube. Also, instead of the liquid crystal display board as the recording display 9 for printing, a self-luminous display such as a light emitting diode, LED, or CRT that generates a wavelength range that is sensitive to X-ray film may be used. In this case, the light emission fIIto for illumination is not necessary.

FIG. 2 shows a schematic diagram of an automatic loading and recovering apparatus for X-ray sheet film equipped with the apparatus according to the present invention.

The shutter 20 is unlocked and the cassette 21 containing the photographed X-ray sheet film is mounted on the mounting section 22. The lid of the cassette 21 is mounted on the arm 2 based on the rotation of the rotating ring 23.
The opening mechanism 25 is activated by the movement of the magnet 26.
The lid is forcibly opened.

Next, sheet film detector 27 KaXI! l'y
- When the film is detected, the suction device ff128 acts and x! l Adsorb and lift the sheet film. This X-ray sheet film is then sent to a predetermined section 30 via a transport roller 29.

Therefore, with the configuration as described above, the accompanying information is printed on the X-ray sheet film. That is, when the X-ray film is sent to the predetermined section 30, one worker moves the image pickup tube 31. The size and position of the burned information on the irradiation record 34 displayed on the monitoring external display 33 via the control circuit 32 and/or the superimposed image of additional information created by the control circuit 32 are checked. When the image is not optimal, the input switch section 35a
, 35b to display the optimum image, and after operating the external force switch section 35c to fix the image, the optical shutter 36 is released. As a result, the optimum image displayed on the display unit 37 is illuminated by the light emitting unit 38 and the image forming unit lens system 39
．． The image passes through an optical shutter 36 and is printed onto an X-ray sheet film.

The X-ray film on which the accompanying information has been printed is sent to a receive magazine 41 by a transport roller 40 and collected.

Note that in the case of a device directly connected to an automatic developing machine, the toner is directly carried into the automatic developing machine and developed. Further, in the empty cassette 21, X-ray sheet films corresponding to the size of the cassette 21 detected by the microswitch 42 are stored in the supply magazines 43a, 43b, 43.
c) and loaded via the transport device 44.

(Effects of the Invention) As described above, this invention reads the information recorded on the subject as an image signal, creates an information image signal separate from the image signal, superimposes both images, and records it on a recording medium. A wide range of image processing can be easily performed. Therefore, it is no longer necessary to occupy a large space for variable magnification and to focus the optical system, which was required in the past, and there is a large degree of freedom in the layout of the device. It can be recorded with. Furthermore, since one worker can monitor the image information, more efficient and highly accurate recording is possible.
