  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. A medical film printing apparatus according to an embodiment of the present invention is a medical film obtained by developing an image photographed by a medical diagnostic imaging apparatus such as an ultrasonic diagnostic apparatus, a CT diagnostic apparatus, an MRI diagnostic apparatus, or an X-ray diagnostic apparatus. This is for printing identification information such as the patient's name, date of birth, and patient number. The medical film is a transmissive material, and an image taken by the diagnostic imaging apparatus can be visually observed by irradiating light from a light source from behind the medical film.

  FIG. 1 is an explanatory view showing a first embodiment of a medical film printing apparatus according to the present invention, and FIG. 2 is a block diagram showing the structure of the medical film printing apparatus. FIG. 3 is a flowchart showing the operation of the medical film printing apparatus, and FIG. 4 is a flowchart showing the information printing operation of the medical film printing apparatus. FIG. 5 is an explanatory view showing an example of a medical film printed by the medical film printing apparatus.

  In the figure, a medical film printing apparatus 1 is incorporated in a developing device 6 for a medical film 5 connected to an image diagnostic apparatus (not shown), and prints patient identification information taken on a developed medical film 5a. Is. Structurally, the medical film printing apparatus 1 includes a film tray 16 serving as a main body housing, a developed medical film 5a and an endless belt-like film transport mechanism 15a to 15c for transporting the printed medical film 5b, and a printer 11. Etc. As shown in FIG. 2, the electronic circuit portion includes a computer 10 that controls the entire apparatus and a card reader 12 that reads information on a medical card (medical card) 8. When the medical film printing apparatus 1 is used, the film tray serving as the main body casing is positioned on the film tray 6b from which the developed film 5a of the developing device 6 is discharged. 16 is arranged.

  Here, unlike the developing device 6, the printer 11 is a printing unit that performs printing using a reflective material on the developed medical film 5 a that is a transparent material. The reflective material, like toner and ink, can be visually observed with normal indoor lighting or natural light. In addition, if the printed identification information can be visually observed without using the transmitted light from the light source, it is not limited by the material and color of the reflective material. Examples of the printer 11 include an ink jet printer and a ribbon printer. Moreover, you may print by a thermal transfer system.

  The card reader 12 is for inputting identification information such as the name, date of birth, and patient number of the patient to be inspected recorded on the examination card 8 into the medical film printing apparatus 1 and inputting data of the identification information. Means. That is, the identification information printed on the developed medical film 5a is the patient's name, date of birth, patient number, and the like. Note that the identification information to be printed is not limited to such information, and is not limited to characters but may be symbols or images as long as it is information that can distinguish patients developed on the developed medical film 5a. It doesn't matter. Further, when the identification number is captured, it is not always necessary to use an external recording medium, and the operator may manually input the identification information directly into the medical film printing apparatus 1.

  In this embodiment, the examination card 8 is used as a medium for reading the identification information and the card reader 12 reads the identification information. However, any recording medium on which the identification information is recorded may be used, and the card reader 12 is used. It is not necessarily limited to. For example, it may be printed as a bar code in which identification information is not magnetically recorded like the examination card 8 and read by a bar code reader. Further, although the computer 10 is used as means for controlling the apparatus, the computer 10 is not limited to the computer 10 as long as the apparatus can be controlled.

  Next, a series of operations of the medical film printing apparatus 1 starting from photographing will be described. In the following description, the reference numerals in parentheses correspond to the reference numerals in the flowcharts of FIGS. First, in photographing a patient, patient identification information is collected (S101). This collection of identification information is basically performed when a patient first visits the hospital. The diagnosis card 8 is created based on the collected identification information (S111), and the identification information is registered in a management database or the like (S102). The examination card 8 is not used only for the medical film printing apparatus 1 and is issued before photographing. However, if it is used only for this apparatus, it is not always necessary to collect identification information before photographing. . However, by using the diagnosis card 8 that is commonly used for other examinations, examination reservations, and consultation fee requests, management of identification information can be facilitated and the number of recording media to be handled can be reduced. Can be simplified.

  Next, in order to prevent mistakes such as patient mistakes, the patient is actually photographed by a medical image diagnostic apparatus such as an ultrasonic diagnostic apparatus, CT diagnostic apparatus, MRI diagnostic apparatus, or X-ray diagnostic apparatus. Confirm patient. Actually, the identification information of the patient and the patient are collated between the examination card 8 and the medical record, or by asking the patient the name and date of birth (S103). After confirming the patient to be imaged (S103-OK), imaging is performed by the diagnostic imaging apparatus (S104). The result photographed by the diagnostic imaging apparatus is sent to the developing device 6 for development on the medical film 5, and is developed and output to the medical film 5 by the developing device 6 (S105). The number of developed medical films 5a to be developed varies depending on the type of photographing, but is plural for one patient.

  Next, identification information is printed on the developed medical film 5a output from the developing device 6 using the medical film printing apparatus 1 (S107). Specifically, first, the examination card 8 is inserted into the card reader 12 of the medical film printing apparatus 1 (S201), and the patient identification information taken from the examination card 8 is read (S202). The read identification information is displayed on the screen of the computer 10 to confirm the developed medical film 5a to be printed and the identification information to be printed (S203). When it is determined that the identification information is mistaken (S203-NG), the identification information is read again to prevent mistakes (S201 to S203).

  After confirming the identification information (S203-OK), the developed medical film 5a is loaded into the medical film printing apparatus 1 (S204). There is no particular problem when the number of developed medical films 5a of one patient is one, but in the case of a plurality of sheets, it is necessary to input the number of developed medical films 5a. In the case of the medical film printing apparatus 1 of the present embodiment, the developed medical film 5a that has come out from the discharge port 6a of the developing device 6 is put in by being placed on the film transport mechanism 15a. The developed medical film 5a placed on the film transport mechanism 15a is transported to the printable area of the printer 11 by the film transport mechanisms 15a and 15b, and the identification information is printed by the printer 11 (S205).

  The printing on the developed medical film 5a will be described. First, on the developed medical film 5a, the human body image 5ba and the diagnostic information 5bb in the printed medical film 5b illustrated in FIG. 5 are developed. The human body image 5ba and the diagnostic information 5bb are developed as a transmissive image on the medical film 5 which is a transmissive material, and can be viewed by irradiating transmitted light from a light source such as a viewer. It is. Printing is performed on such a developed medical film 5a with a material that can be visually observed in the room, such as normal lighting or natural light, such as toner or ink, which is a reflective material. That is, the patient's name, date of birth, patient number, and the like are printed on the surface of the developed medical film 5a, for example, with white ink.

  As described above, since the medical film printing apparatus 1 prints identification information on the developed medical film 5a using a reflective material such as ink, the information can be easily visually recognized without using a light source such as a viewer. Can do. In particular, in hospitals or the like that handle medical films 5 of many patients at the same time, confirmation for preventing patient confusion is important. However, since the identification information of the printed medical film 5b can be visually confirmed, the efficiency of the confirmation work can be improved. Can be improved.

  The identification information to be printed is not limited to character information such as the patient's name, date of birth, and patient number, but may be a symbol as shown by a mark 5be in FIG. As symbols, there are those that clearly indicate the sex, and those that clearly indicate the diagnostic imaging apparatus, the imaging region, and the like. In addition to white, the color to be printed is not limited to white as long as it can be visually observed with normal indoor lighting or natural light, and may be a color such as a fluorescent color or a metal color. Further, as shown in the identification information printing unit 5bc of FIG. 5, the identification information 5bd may be represented by white.

  Further, it is possible to print a portrait of a patient photographed with a digital camera as an image. The patient may be imaged at the time of collection of identification information at the time of issuing the examination card 8 (S101), at the time of confirmation of identification information immediately before imaging (S103), or just before the identification information is printed. The re-collection of patient identification information (S106) may be performed. However, since the patient's appearance constantly changes, it may be possible that the image is old when the examination card 8 is issued. Therefore, it is preferable to obtain the image just before printing. Further, the image is not limited to a portrait, and may be any identification information for identifying a patient such as a sign or a picture handwritten by the patient himself. By printing the patient's portrait as an image, it is obvious which patient the medical film 5 belongs to, and it is easy to prevent the patient from being mistaken.

  In general, since the medical film 5 is a blackish color, first, the background printing is performed with a color such as white, and then the identification information is printed on the background printing with another color. Also good. By applying the base printing, printing with an arbitrary color can be performed without being affected by the color of the medical film, and the visibility of identification information to be printed can be improved. In particular, a clearer image can be printed by printing the image on the base printed. Moreover, since the color to be printed can be arbitrarily selected without being influenced by the color of the medical film 5, photographic printing is also possible.

  The printed medical film 5b after printing is discharged to the film tray 16 by the film transport mechanisms 15a and 15c (S206). The medical film printing apparatus 1 according to the present embodiment includes film transport mechanisms 15a to 15c and is configured to perform printing while automatically transporting the medical film 5. However, printing may be performed by manually setting the printer 11 one by one. However, since it is necessary to print a plurality of sheets continuously by one patient, it is possible to improve work efficiency by providing the film transport mechanisms 15a to 15c as in this embodiment.

  In addition, since the medical film printing apparatus 1 of the present embodiment can be used by being attached to a conventional developing device 6, it is not necessary to renew the developing device 6, and the installation cost can be reduced.

  The medical film printing apparatus 1 according to the first embodiment has been described as being used in a state in which the medical film printing apparatus 1 is mounted on a conventional developing apparatus 6, but the medical film printing apparatus 1 may not be used depending on the shape of the developing apparatus. In the present embodiment, a medical film printing apparatus 2 that can be used alone instead of being placed on the developing device 6 will be described.

  FIG. 6 is an explanatory view showing a second embodiment of the medical film printing apparatus according to the present invention.

  In the figure, a medical film printing apparatus 2 is for printing identification information of a photographed patient on a developed medical film 5a developed by a developing apparatus for a medical film 5 connected to an image diagnostic apparatus. The medical film printing apparatus 2 structurally includes a film stocker 28 on which the developed medical film 5 a is first placed, a base 23 of the printer 21, and a developed medical film 5 a from the film stocker 28 to the base 23. It consists of an endless belt-like film up-and-down mechanism 27 to be fed and a film tray 29 for storing the printed medical film 5b. In the base 23, film feeding rollers 26a and 26b for feeding the developed medical film 5a one by one are supported by a gate-shaped roller supporter 26. Further, a film feed roller 25 for feeding the developed medical film 5a on the base 23 is provided so as to cross almost the center of the base 23. Further, plate-like rail support bases 24 are provided on both sides of the base 23, and the printer 21 is slidably provided on two slide rails 24 a spanned between the rail support bases 24. .

  In addition, as an electronic circuit portion, it is composed of a control device 20 that controls the entire device and a card reader 22 that reads information on a medical card (medical ticket) 8. A card reader 22 and a base 23 are connected to the control device 20. Note that the printer 21 and the card reader 22 are the same as those of the medical film printing apparatus 1 of the first embodiment, and thus description thereof is omitted. Further, the control device 20 performs the same function as the computer 10 and can be regarded as a dedicated computer that controls the entire device. Since the identification information to be printed is the same as that in the first embodiment, the description thereof is omitted.

  Next, the operation of the medical film printing apparatus 2 will be described. In the following description, the reference numerals in parentheses correspond to the reference numerals in the flowcharts of FIG. First, the examination card 8 is inserted into the card reader 22 of the medical film printing apparatus 2 (S201), and the patient identification information taken from the examination card 8 is read (S202). By confirming the read identification information on the screen of the control device 20 or the like, the developed medical film 5a to be printed and the identification information to be printed are confirmed (S203). When it is determined that the identification information is mistaken (S203-NG), the identification information is read again to prevent mistakes (S201 to S203).

  After confirming the identification information (S203-OK), the developed medical film 5a is placed on the film stocker 28. The developed medical film 5a to be placed does not have to be a single sheet, but may be placed on one patient's film at the same time. Next, when the control device 20 is instructed to start printing, the control of the control device 20 causes the film up-and-down mechanism 27 to move up the base 23 side while rotating the endless belt, and the developed medical film 5a of the film stocker 28 is used as the base. Send to table 23. The developed medical film 5a sent to the base 23 is first sent one by one to the film feed roller 25 in the back direction of the base 23 by the film feed rollers 26a and 26b.

  One developed medical film 5 a sent to the film feed roller 25 is sent under the printer 21 while being positioned by the film feed roller 25. At this position, the printer 21 prints identification information on the developed medical film 5a in accordance with an instruction from the control device 20 (S205). The printed medical film 5b is discharged from the base 23 toward the film tray 29 by the film feed roller 25 (S206). Thereby, the printing of one developed medical film 5a is completed. This printing operation is repeated, and all the developed medical film 5a placed on the film stocker 28 is printed. The identification information printed on a plurality of developed medical films 5a for one patient may be the same, or different information may be printed in consideration of page information and the like. The printer 21 may be one that prints by a thermal transfer method. In this case, a part of the base 23 rises (not shown) and the printer 21 and the developed medical film 5a are printed in close contact with each other. To.

  With the medical film printing apparatus 2 that can be used alone without being attached to the developing apparatus as described above, printing on the medical film 5 is possible without changing the existing developing apparatus, and the cost associated with the image diagnostic apparatus is reduced. It is possible to suppress.

  The medical film printing apparatuses 1 and 2 according to the first and second embodiments use an off-line recording medium such as a medical card 8 when acquiring identification information. However, it is also possible to acquire identification information from a database that has already been constructed via a network, and a mode using a network will be described.

  FIG. 7 is a block diagram showing a third embodiment of the medical film printing apparatus according to the present invention.

  In the figure, a medical film printing apparatus 3 is connected to an image diagnostic apparatus for developing a medical film 5 and printing identification information of a photographed patient on the developed developed medical film 5a. . The medical film printing apparatus 3 includes a control unit 30 that controls the entire apparatus, a developing apparatus 35 that develops the medical film 5, and a printer that prints identification information on the developed medical film 5a developed by the developing apparatus 35. 31, and communication interfaces (communication I / F) 33 and 34 for connecting to the developing device 35 and external devices via a network 38. Since the printer 31 is the same as the medical film printing apparatus 1 of the first embodiment, the description thereof is omitted. Further, the control device 30 controls the network 38 in addition to the same functions as those of the computer 10 and can be regarded as a dedicated computer that controls the entire device. Since the identification information to be printed is the same as that in the first embodiment, the description thereof is omitted.

  The medical film printing apparatus 3 is connected to a plurality of image diagnostic apparatuses 7 a to 7 c via a network 38. The image diagnostic apparatuses 7a to 7c do not have to be the same image diagnostic apparatus, and may be apparatuses capable of performing different types of imaging. The network 38 is provided with a card reader 32a controlled by one card reader controller 32. The card reader control unit 32 and the card reader 32 a are for sending the identification information recorded on the examination card 8 to the medical film printing apparatus 3 via the network 38. Furthermore, the medical film printing apparatus 3 is connected to a database in which identification information is registered in advance via a network 38.

  In this embodiment, the diagnosis card 8 is used as a medium for reading the identification information, and the card reader 32a actually reads the identification information. However, any recording medium on which the identification information is recorded may be used. It is not limited to what is used. For example, a bar code reader that can be connected to the network 38 may be used.

  Next, the operation of the medical film printing apparatus 3 of this embodiment will be described. In the following description, the reference numerals in parentheses correspond to the reference numerals in the flowcharts of FIGS. First, when examining a patient, patient identification information is collected (S101). This collection of identification information is basically performed when the patient first visits the hospital. The diagnosis card 8 is created based on the collected identification information (S111), and the identification information is registered in the database 37 connected to the network 38 (S102).

  Next, imaging of the patient is performed by the image diagnostic apparatuses 7a to 7c, but prior to that, the patient is confirmed in order to prevent mistakes such as patient misunderstanding. Actually, the identification information of the patient and the patient are collated between the examination card 8 and the medical record, or by asking the patient the name and date of birth (S103). After confirming the patient to be imaged (S103-OK), imaging is performed by the image diagnostic apparatuses 7a to 7c (S104). The result photographed by the image diagnostic apparatus is sent to the developing device 35 via the network 38 for development on the medical film 5, and is developed and output to the medical film 5 by the developing device 35 (S105). The number of developed medical films 5a to be developed varies depending on the type of photographing, but is plural for one patient.

  Next, identification information is printed on the developed medical film 5a output from the developing device 35 (S107). Specifically, first, the control unit 30 acquires patient identification information taken from the database 37 via the network 38. The acquired identification information is displayed on the screen of the control unit 30 or the like to confirm the developed medical film 5a to be printed and the identification information to be printed (S203). When it is determined that the identification information is mistaken (S203-NG), the identification information is read again to prevent mistakes (S201 to S203). After confirmation of the identification information is completed (S203-OK), the developed medical film 5a is printed with the identification information by the printer 31 to become a printed medical film 5b.

  As described above, by acquiring the identification information via the network, it is not necessary to input the identification information again, it is possible to efficiently use the past resources without any trouble, and the operation is easy. Also, by providing the card reader 32a on the network 38, the card reader 32a can be shared by the plurality of medical film printing apparatuses 3 and 3a, and the operating efficiency of the apparatus can be improved. In this case, identification information can be acquired without providing the database 37 on the network 38. Further, as shown in FIG. 7, by providing the database 37 and the card reader 32a on the network 38, the identification information can be confirmed by the database 37 and the examination card 8, and the reliability of the identification information to be printed is confirmed. Can be improved. If the patient's name is stored only in katakana or romaji on the examination card 8, information on the patient's kanji is obtained from the database 37 using the information on the examination card 8 as a key, and the identification information is in kanji. It is also possible to print. Many of the conventional developing devices are made in foreign countries, and the identification information is mostly developed only with alphanumeric characters, and the identification information is printed in kanji, so that it not only looks good, but the contents are easy to understand Can also be improved. In the case where information is previously recorded in Chinese characters on the diagnostic card 8, the identification information can be printed in Chinese characters, which can improve not only the appearance but also the ease of understanding the contents. it can.

  In this embodiment, an example in which the developing device 35 is incorporated in a part of the medical film printing apparatus 3 is shown, but the present invention is not limited to such a configuration. For example, a plurality of medical film printing apparatuses 3 and 3 a provided on the network 38 can be shared by a plurality of image diagnostic apparatuses 7 a to 7 c provided on the network 38. Unlike the case where the medical film printing apparatuses 3 and 3a and the image diagnosis apparatuses 7a to 7c are connected on a one-to-one basis, the entire system continues to operate even if one of the medical film printing apparatuses 3 and 3a stops. Therefore, the time from photographing to outputting a medical film is hardly increased while reducing the cost of the entire system.

  The medical film printing apparatuses 1 to 3 according to the first to third embodiments acquire the identification information from an external recording medium such as the medical card 8 when acquiring the identification information. However, it is also possible to acquire identification information from a developed medical film, and such a form will be described.

  FIG. 8 is an explanatory view showing a fourth embodiment of the medical film printing apparatus according to the present invention. FIG. 9 is a flowchart showing the operation of the medical film printing apparatus.

  In the figure, a medical film printing apparatus 4 is for printing identification information of a photographed patient on a developed medical film 5a developed by a developing apparatus for a medical film 5 connected to an image diagnostic apparatus. The medical film printing apparatus 4 is structurally composed of a film stocker 28, a base 23 of the printer 21, a film vertical mechanism 27, a film tray 29, a control device 40, and the printer 21. This is the same as the medical film printing apparatus 2 of the second embodiment. In addition to these, the medical film printing apparatus 4 includes a scanner 41 which is a scanning unit that reads identification information developed on the developed medical film 5a. The control device 40 is similar to the control device 20 of the medical film printing apparatus 2 in that it performs control for printing the identification information on the developed medical film 5a. Has the ability to get.

  The scanner 41 is for electronically acquiring an image of a transparent material, and a light source (not shown) is provided below the scanner 41. The developed medical film 5a is sent so as to pass between the scanner 41 and the light source.

  Next, the operation of the medical film printing apparatus 4 will be described. In the following description, the reference numerals in parentheses correspond to the reference numerals in the flowcharts of FIG. First, the developed medical film 5 a is placed on the film stocker 28. The developed medical film 5a to be placed does not have to be a single sheet, but may be placed on one patient's film at the same time. Next, when the control device 20 is instructed to start printing, the control of the control device 20 causes the film up-and-down mechanism 27 to move up the base 23 side while rotating the endless belt, and the developed medical film 5a of the film stocker 28 is used as the base. Send to table 23. The developed medical film 5a sent to the base 23 is first fed one by one by the film feed rollers 26a and 26b toward the film feed roller 25 in the back direction of the base 23 (S301).

  One developed medical film 5 a passes under the scanner 41 while being fed to the film feed roller 25. At this time, the scanner 41 scans the developed medical film 5a (S303), and the control device 40 acquires identification information from the scanned image information (S303). Specifically, for example, in the case of the medical film 5 developed as shown in FIG. 5, identification information 5 ab such as the name and date of birth of the developed patient is acquired from the scanned image information. Will be. In order to efficiently obtain the identification information from the image information, it is possible to optimize the position where the identification information is developed, the size of the characters, the contents, etc. in advance.

  Next, confirmation is made between the developed medical film 5a to be printed and the identification information to be printed by displaying the acquired identification information on the screen of the control device 40 or the like (S304). When it is determined that the identification information is mistaken (S304-NG), mistakes are prevented by acquiring the identification information again (S301 to S304).

  After passing under the scanner 41 and confirming the identification information (S304-OK), the developed medical film 5a is fed under the printer 21 while being positioned by the film feed roller 25. At this position, the printer 21 prints identification information on the developed medical film 5a in accordance with an instruction from the control device 40 (S305). The printed medical film 5b is discharged from the base 23 toward the film tray 29 by the film feed roller 25 (S306). Thereby, the printing of one developed medical film 5a is completed. This printing operation is repeated, and all the developed medical film 5a placed on the film stocker 28 is printed.

  As described above, since the identification information developed on the developed medical film 5a is read by the scanner 41, it is not necessary to use another recording medium or to input the identification information again, and the operation is easy. As in the other embodiments, in addition to the scanner 41, identification information can be acquired from data input means such as a card reader or a database. By comparing the identification information input by the other data input means with the identification information read by the scanner 41 and judging the difference, it is possible to prevent the medical film 5 from being mistaken and to be misread by the scanner 41 and accurately. The identification information can be printed on the developed medical film 5a. It is also possible to attach the scanner 41 to the medical film printing apparatus 1 of Embodiment 1 and acquire identification information.

  In the medical field, in the case of storing a medical film, in view of the fact that it is stored in a paper bag, a mode for handling a paper bag for storing a medical film will be described.

  FIG. 10 is an explanatory view showing a fifth embodiment of the medical film printing apparatus according to the present invention.

  The medical film printing apparatus described in this embodiment is the same as that described in the other embodiments, and only different points will be described. The difference is that the medical film printing apparatuses 1 to 4 are provided with sensors that are film discriminating means for discriminating between the medical film 5 and the paper bags 45 and 47 for storing the medical film 5. This sensor can determine whether it is a medical film 5 or a paper bag 45, 47, so that it can send detection information as electronic information to the computer 10 and the control devices 20, 30, 40. That's fine.

  Next, the operation of the medical film printing apparatus provided with the sensor will be described. First, the developed medical films 46a, 46b, 48a to 48c of a plurality of patients are divided by paper bags 45, 47 and set in the overlapping medical film printing apparatus. In the example shown in FIG. 10, the developed medical films 46a and 46b are for one person, and a paper bag 45 stores these two medical films. Further, the developed medical films 48a to 48bc are for one person, and a paper bag 47 stores these three medical films.

  The medical film printing apparatus sends the developed developed medical films 46a, 46b, 48a to 48c and the paper bags 45, 47 one by one to the sensor, and determines whether the sent medical film 5 or the paper bags 45, 47 are sent. . In the case of FIG. 10, the paper bag 45 is sent first, and the paper bag and the sensor determine and send the information to the computer 10 and the control devices 20, 30, and 40. As a result, the computer 10 and the control devices 20, 30 and 40 determine that the developed medical films 46a and 46b of one patient are sent until the next detection of the paper bag 47, and print the identification information. I will do it. After the developed medical films 46a and 46b have been printed, when the sensor determines the paper bag 47, the medical film printing apparatus determines that the other developed medical films 48a to 48c will be sent. Print the identification information.

  As described above, the developed medical films 5a of a plurality of patients are separated by the paper bags 45 and 47, and each time the sensor detects the paper bags 45 and 47, it is recognized that the developed medical film 5a of another patient is changed. Since the identification information is printed on the developed medical film 5a in units of patients, it is not necessary to manage the number of medical films 5 per patient, and the operation becomes easy.

  Further, the paper bags 45 and 47 pass through the printers 11, 21 and 31 in the same manner as the developed medical films 46 a, 46 b and 48 a to 48 c, and the printers 11, 21 and 31 store the identification information 45 a and 47 a in the paper bags 45 and 47. May be printed. Since the printers 11, 21, 31 can print the identification information on the paper bags 45, 47 for storing the medical film 5, the identification information is automatically written on the paper bags 45, 47, thereby facilitating the work.

  By printing identification information using a reflective material on a developed medical film that is a transparent material, the information can be easily viewed without using a light source. It can also be applied to uses related to data.
