The setting position of the X-ray absorber unit 11 is easily found from the setting positions of longitudinal and lateral movement axes 14 and 15, so the recording position and photographic area of the attendant information on the X-ray film 2 are also found with high precision.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for recording incidental information such as a person's name and medical history on a recording medium, and particularly relates to an incidental information recording device for recording incidental information at an arbitrary position on a recording medium. It is.

(Background of the Invention) As an accompanying information recording device that photographs an image on a recording medium and records information accompanying the photographed image on the recording medium, for example, when taking an X-ray photograph of a human body on an X-ray film, Some cameras also record accompanying information such as the name of the person being photographed and the date and time of the photograph. This is preferable in terms of speeding up medical decisions based on X-ray films and preparing data.

Conventionally, when an X-ray cassette is used to print incidental information onto the X-ray film, lead plates are pasted in advance to predetermined locations on the X-ray cassette to prevent the transmission of X-rays. A process is adopted in which a part of the X-ray film stored in the camera, other than directly below the vertical plate, is exposed to X-rays as an X-ray photographing area, and then accompanying information is burned into the part of the film that has not been exposed to X-rays in a dark room. has been done. Furthermore, in the case of an X-ray imaging device, a portion of the X-ray intensifying screen was similarly deleted to print accompanying information.

(Problem to be solved by the invention) As mentioned above, x! A conventional device for printing incidental information on a film is:
In order to prevent radiation exposure, the X-ray intensifying screen with a lead plate fixed to it was removed. However, in such a device, the position of the burned incidental information cannot be changed arbitrarily during X-ray photography. The burned accompanying information will be moved from the desired position on the X-ray film, and there is a possibility that some of the information may be missing. In addition, the X-ray imaging area on the X-ray film is not always constant, and in this case, the position of the lead plate and the area from which the intensifying screen is removed must be slightly changed each time, which is extremely troublesome. becomes.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an incidental information recording device that allows incidental information to be extremely easily recorded at any location on a recording medium.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides incidental information recording for photographing an image on a recording medium and recording information accompanying the photographed image on the recording medium. In the apparatus, an exposure amount control means that can be moved and set at any position on a recording medium set at a predetermined position and controls the amount of light, and accompanying information is provided at a set position t of the exposure amount control means on the recording medium. It is characterized by comprising a recording means for recording.

(Function) According to the present invention, by moving or setting the exposure amount control means to an arbitrary position on the recording medium, it is possible to record the accompanying information in an optimal area suited to the photographic subject and conditions.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of an X-ray photographing and printing apparatus to which the accompanying information recording apparatus of the present invention is applied, and FIG. 2 is a front view thereof.

In the figure, reference numeral 1 is the main body of the apparatus, and inside the main body 1 of the apparatus there is a supply magazine 3 in which unexposed X-ray film 2 as a recording medium is stored, and accompanying information 1 of the X-ray image taken, such as the date and time of the image taken. A receive magazine 4 is provided for storing an X-ray film on which information such as minutes and seconds and personal records are printed.

The unexposed X*=ilm 2 stored in the supply magazine 3 is sucked and taken out by the suction plate 5, and
It is conveyed by the rotation of the pair of conveyance rollers 6 and installed at the X-ray imaging position.

This installation is carried out by inserting the unexposed X-ray film 2, conveyed via the conveyor rollers 6, between the intensifying screens 7.7.

The intensifying screens 7.7 are installed facing each other so that the interval between them can be adjusted, and the interval between them can be widened or brought into close contact with each other by driving the power system 8.

The power system 8 includes a rotating reel 8a, a transmission shaft 8b whose one end is supported by the reel 8a, one end supported by the transmission shaft 8b, and an elastic material (for example, sponge) attached to the inner intensifying screen 7 at the other end. 9 and a drive shaft 8C coupled via a plate material 10.

Unfinished jtxm film 2 due to the rotation of the rotating reel 8a
When inserting the intensifying screen 7, the drive shaft 8C is moved to the right side and the intensifying screen 7,
7 to make it easier to insert the unexposed X-ray film 2,
After setting the unexposed X-ray film 2 at a predetermined position, the drive shaft 8C is moved to the left, the interval between the intensifying screens 7.7 is narrowed, and the unexposed X-ray film 2 is held tightly (pressed).

In this way, the unexposed X-ray film 2 is set at the photographing position, a human body or the like is irradiated with X-rays, and photographed, and the photographed image is recorded on the unexposed X-ray film 2.

Here, in order to leave an unexposed space on the photographed X-ray film to record incidental information regarding the photographing, the X-ray absorber unit 11, which is the exposure control means, is moved in the horizontal direction ( It is installed so that it can be moved arbitrarily in the X direction) and in the vertical direction (X direction). This X-ray absorber unit 1
Reference numeral 1 is made of lead material and is installed so as to be movable in the horizontal direction (X direction) and vertical direction (X direction). A transparent acrylic plate 12 is provided on the front side of the device main body 1.

X-ray absorber unit) 1114 It is constructed as shown in Fig. 3.
For example, an X-ray absorber 11a made of lead material, a magnetic material ttb made of a permanent magnet, and a slippery surface 11 treated with Teflon.
It has a laminated structure of c. Since the magnetic body 11b of the X@absorber unit) 11 is attracted by the magnetic force of the electromagnet 13, the XM absorber unit) 11 can be moved arbitrarily in the X and Y directions on the surface of the photographic X-ray film.

The electromagnet 13 is attached to the inside of the apparatus main body 1 at the intersection of a vertical movement shaft 14 extending vertically and a horizontal movement shaft 15 extending horizontally. The electromagnet 13 moves in the Y direction along the vertical movement axis 14 together with the horizontal movement axis 15, and also moves in the X direction along the horizontal movement axis 15 together with the vertical movement axis 14. A permanent magnet may be used instead of the electromagnet 13.

As a result, the unexposed X-ray film 2 is exposed to X-rays except for the portion covered by the X-ray absorber unit 11, but the portion covered by the X-ray absorber unit 11 is not exposed.
The accompanying information can be recorded in this part. Since the set position of the X-ray absorber unit 11 can be easily determined from the set positions of the vertical and lateral movement axes 14, 15, the incidental information recording position or imaging area of the X-ray film 2 can also be determined with high precision.

Next, in order to record incidental information on the unexposed portion of the X-ray film 2 and to store the photographed X-ray film 2 in the receive magazine 4, the intensifying screen 7.7 is operated by the power system 8.
After widening the interval, take out the X-ray film 2 from below,
With the conveyance roller 16 which has the same structure as the conveyance roller 6!

An infrared light emitter 17 is placed along the conveyance path by the conveyance rollers 16.
and a photoreceptor 18 are placed facing each other, and the time when the sheet-shaped X-ray film 2 conveyed between the two passes is detected. This detection point is the reference position of the X-ray film 2 in the y direction (yO in FIG. 2), and based on this detection reference position, the installation position of the X-ray absorption pair 14 in the y direction (
yl) in FIG. 2 is determined.

The installation position in the y direction is determined based on the detection reference position yO and the transport speed V of the X-ray film 2. That is, the position of the X-ray film 2 that has arrived at the time when y l /v (sec) has elapsed from the detection point of yO becomes the installation position of the X-ray absorber unit 11.

A printing means, which is a recording means, is provided downstream of the light-emitting body 17, and the light-emitting display body 19 of this printing means is used to print incidental information onto the unexposed portion of the X-ray film 2 through an optical lens 20. The imprinting of incidental information by the 0-light emitting display body 19 moving along the horizontal support shaft 21 is performed based on the time point at which the reference position of the X-ray film 2 is detected by the infrared light emitter 17 and the photoreceptor 18. control is carried out.

In this way, the X-ray film 2 on which the X-ray image has been taken and the accompanying information has been imprinted is stored in the receive magazine 4 by the transport roller 22, and one cycle of operation is completed.

Note that the above description is just one example, and it goes without saying that various modifications are possible.
