The seat 101 has an opening 105 on the bottom surface. The seat portion 101 is fixed horizontally to the case 20 with the bottom portion facing downward.

  Similar to the seat portion 101, the moving portion 102 includes a base portion 106 formed by bending a metal plate into a trapezoidal shape, and overhanging portions 107 and 107 projecting outward from both sides of the base portion 106. The overhanging portions 107 and 107 are provided with sliding grooves 108 and 108 extending in the same direction, respectively. The moving part 102 is accommodated in the area 104 of the seat part 101, straddles the opening 105 provided on the bottom surface of the seat part 101, and the sliding grooves 108 and 108 are respectively formed in the main body part 25 of the detaching device 2. It arrange | positions so that it may extend | stretch in the direction which approaches and leaves | separates with respect to the provided pressure receiving wall 23e. The moving part 102 is inserted from above the sliding groove 108 provided in the overhanging parts 107, 107, and is attached in the seat part 101 by screws 110, 110 screwed into the bottom surface of the base part 106. The moving part 102 is mounted so as not to be detached from the pedestal part 106 by the screws 110 and 110, but to such a degree that it can freely slide on the pedestal part 106. Therefore, the moving part 102 can slide in the direction approaching or separating from the pressure receiving wall 23e.

  The moving part 102 is connected to the seat part 101 via a spring 111. More specifically, the spring 111 has one end fixed to the side wall 101a of the seat portion 101 facing the pressure receiving wall 23e and the other end fixed to the side surface of the base portion 106. For this reason, the moving part 102 is urged | biased by the side wall 101a side with the spring 111, and the side surface of the moving part 102 is always contact | abutting to the side wall 101a.

  Further, as shown in FIG. 3, two sensors 117 and 118 are attached to the moving part 102 via a support plate 116 attached to the side of the base part 106. As shown in FIG. 9, the sensor 117 transmits a detection signal when an eccentric portion 115 of an eccentric cam 112 (pressing member), which will be described later, is located closest to the pressure receiving wall 23e. As shown in FIG. 6, the sensor 118 transmits a detection signal when the eccentric cam 115 exists at a position farthest from the pressure receiving wall 23e. The sensor 117 is attached to a position where the eccentric part 115 can be detected when the eccentric part 115 comes closest to the pressure receiving wall 23e of the main body part 25. The sensor 118 is attached to a position where the eccentric part 115 can be detected in a state where the eccentric part 115 is farthest from the pressure receiving wall 23e of the main body part 25.

  The main part of the drive unit 103 includes an eccentric cam 112 and a motor 113, and is integrally attached to the moving unit 102. More specifically, the motor 113 is a power source of the drive unit 103 so that the rotation shaft protrudes from the back surface side of the base unit 106 of the moving unit 102 toward the front surface side (from the lower side to the upper side). It is fixed.

  The motor 113 can rotate in the forward direction (arrow A direction in FIG. 1) or the reverse direction (arrow B direction in FIG. 1) according to the energization direction. An eccentric cam 112 is attached to the rotation shaft of the motor 113 so as to be rotatable in a horizontal state with respect to the seat portion 101. The eccentric cam 112 is a so-called plate cam represented by a mushroom cam, a tangential cam, a disc cam, a mushroom cam, a triangular cam, or the like, or a plate cam called a peripheral cam. In the present embodiment, a mushroom cam is employed as the eccentric cam 112.

  The rotation shaft of the motor 113 is connected to an eccentric position of the eccentric cam 112, and the eccentric portion 115 is always present at a position away from the pressure receiving wall 23 e of the main body portion 25. When the motor 113 is operated, the eccentric cam 112 rotates around the rotation axis of the motor 113 as shown in FIG. 6, and the portion on the eccentric portion 115 side approaches the pressure receiving wall 23e, and eventually the contour of the eccentric cam 112 is reached. The portion comes into contact with the pressure receiving wall 23e. When the rotation shaft of the motor 113 is further rotated, the main body 25 is pushed by the contour portion of the eccentric cam 112. As a result, the main body portion 25 rotates about the support shaft 26 as indicated by an arrow B in FIG. 7, and the head portion 21 comes close to the tray 10 existing at a position adjacent to the detaching device 2.

  The detaching device 2 uses the power transmitted from the driving unit 24 to the head unit 21 and the card feeding unit 22 to insert / remove the card 13 with respect to the mounting unit 14 of the tray 10 or move the card 13. The drive unit 24 uses a motor 18 attached to a substantially central portion in the extending direction of the main body unit 25 as a power source, and transmits torque to the head unit 21 and the card feeding unit 22. The head portion 21 is a main portion of a detaching mechanism for detaching the card 13 from the mounting portion 14 provided on the side surfaces 11 and 12 of the tray 10. As shown in FIG. 2, the head unit 21 includes an output shaft 45 that rotates by receiving torque transmitted from the motor 18, and a roller 58 (card moving means) that is integrally attached thereto. The head unit 21 rotates the roller 58 in a state of surface contact with the card 13 to remove the card 13 from the mounting unit 14 of the tray 10 or to mount the card 13 sent from the card feeding unit 22 side. 14 can be inserted.

  The card feeding unit 22 is configured by a card passage 70 constituted by a gap that allows the card 13 to pass through and a card feeding mechanism 75. The card passage 70 includes strip-shaped guide members 61 and 61 attached to the frame plates 23a and 23b, and a guide frame 71 (detaching side wall surface) and a guide frame 72 (attached between the frame plates 23a and 23b). (Pressure-receiving side wall surface). The card passage 70 is on the front side 25 a of the main body 25 and is adjacent to the head portion 21. The card-side passage 60 is provided at the boundary between the card display changing device 3 and the head-side card entrance 60. 76 is a slit-like passage that is curved in a substantially “S” shape that connects to 76. The feed-side card entrance / exit 76 is a terminal portion on the boundary side 25c side of the main body 25, and is a vertically long portion formed at a substantially central portion in the thickness direction of the main body 25, that is, an intermediate portion between the front 25a side and the back 25b side. Thus, it is a slit-shaped opening that allows one card 13 to pass through.

  The card feeding mechanism 75 is adjacent to the card passage 70 on the back surface 25b side with respect to the roller shafts 81, 82, 83 arranged at predetermined positions at positions adjacent to the back surface 25b side. The main part is constituted by the roller shafts 85 and 86 arranged at the positions. The roller shafts 81 to 83 are attached so as to be rotatable relative to the frame plates 23a and 23b, respectively. Rubber rollers 87 to 89 (card feeding means) are attached to a substantially central portion in the axial direction of the roller shafts 81 to 83. The rollers 87 to 89 rotate integrally with the roller shafts 81 to 83, and are used to feed the card 13 in a predetermined direction by making surface contact with the card 13 introduced into the card passage 70. The rollers 87 to 89 are exposed toward the card path 70 from a roller exposure window 77 provided on the guide frame 71 disposed on the front surface 25 a side, and can be brought into surface contact with the card 13 flowing in the card path 70. Has been.

  On the other hand, the roller shafts 85 and 86 are attached so that they cannot rotate relative to the frame plates 23a and 23b, respectively. Auxiliary rollers 91 and 92 are attached to the substantially central portions in the axial direction of the roller shafts 85 and 86 so as to be rotatable relative to the roller shafts 85 and 86, respectively. The auxiliary rollers 91 and 92 are arranged at predetermined intervals along the extending direction of the card passage 70, respectively, and are arranged at positions corresponding to between the above-described rollers 87 and 88 and between the rollers 88 and 89, respectively. Yes. The auxiliary rollers 91 and 92 are rollers for assisting the flow of the card 13 in the card passage 70.

  Next, the operation of the display change device 1 according to the embodiment will be described with reference to the drawings. The operation of the display change device 1 is controlled by a control device (not shown). When the control device detects that the supply of the tray 10 to the transport device 15a is started, the transport device 15a is activated and the tray 10 is transported further downstream. When the control means confirms that the tray 10 has arrived in front of the display change device 1, the control means stops the transport device 15a. Thereafter, the control means operates the position adjustment mechanism unit 100 to remove the card 13 mounted on the tray 10 and brings the head unit 21 of the detaching apparatus 2 closer to the mounting unit 14 of the tray 10.

  More specifically, when the tray 10 arrives at a position adjacent to the head portion 21 of the detaching device 2, the control device energizes the motor 113 of the position adjustment mechanism portion 100, and the motor as indicated by an arrow A in FIG. The rotating shaft 113 is rotated in the positive direction. As a result, the eccentric cam 112 connected to the motor 113 starts to rotate eccentrically, and eventually the contour portion of the eccentric cam 112 abuts against the pressure receiving wall 23e of the detaching device 2 as shown in FIG. When the motor 113 further rotates, the detaching device 2 and the display changing device 1 connected to the card display changing device 3 start to rotate around the support shaft 26 as indicated by an arrow B in FIG.

  When the motor 113 further rotates, the head portion 21 of the detaching apparatus 2 comes into contact with the side surface 11 or the side surface 12 of the tray 10 as shown in FIG. That is, when the head portion 21 of the detaching apparatus 2 comes into contact with the side surface 11 or the side surface 12 of the tray 10, the main body portion 25 is rotated to the movable limit, that is, the main body portion 25 hits the side surface 11 or the side surface 12 of the tray 10. Thus, it is in a state where it cannot be rotated any further.

  Here, the motor 113 of the drive unit 103 rotates until the eccentric portion 115 of the eccentric cam 112 is detected by the sensor 117. That is, when the motor 113 rotates in the positive direction (the direction of arrow A in FIG. 8), that is, the eccentric portion 115 approaches the pressure receiving wall 23e, the eccentric portion 115 is detected by the sensor 117 installed on the pressure receiving wall 23e side. Until the motor 113 is energized. Therefore, the eccentric cam 112 continues to rotate even when the main body 25 reaches the movable limit. Therefore, the reaction force Fr acting in the direction away from the side wall 101 a with respect to the moving part 102 when the eccentric cam 112 presses the pressure receiving wall 23 e of the main body part 25 causes the spring 111 to connect the seat part 101 and the moving part 102. Thus, the pulling force Fa pulling the moving part 102 toward the side wall 101a becomes larger.

  Here, as described above, the moving unit 102 is normally urged toward the side wall 101 a by the spring 111. However, when an external force (reaction force Fr) larger than the pulling force Fa of the spring 111 acts on the moving portion 102 toward the opposite side of the pulling force Fa, the sliding groove 108 is shown in FIG. Along the side wall 101a. Therefore, when the eccentric cam 112 tries to further rotate while the main body 25 is rotated to the movable limit, the reaction force Fr acting on the moving part 102 pulls the moving part 102 toward the side wall 101a. And the moving part 102 is pushed to the side wall 101b side by being guided by the sliding groove 108. As shown in FIG. 9, when the eccentric portion 115 of the eccentric cam 112 is in contact with the pressure receiving wall 23e of the main body portion 25, the detaching apparatus 2 has the roller 58 of the output shaft 45 constituting the head portion 21 mounted on the tray 10. It will be in the state contact | adhered to the surface of the card | curd 13 attached to the part 14 with moderate pressure. In other words, when the moving part 102 escapes from the side wall 101a against the pulling force Fa by the spring 111, the pressing force acting on the main body part 25 by the eccentric cam 112 is relaxed, and the roller 58 is moderately applied to the card 13. It will be in close contact.

  As shown in FIG. 9, when the eccentric portion 115 of the eccentric cam 112 faces the pressure receiving wall 23e, the eccentric portion 115 is detected by the sensor 117, and energization to the motor 113 is stopped. Thereafter, the control device starts energizing the motor 18 that is the drive source of the detaching device 2. When the motor 18 receives power supply and the rotating shaft starts to rotate forward, the torque of the motor 18 is transmitted to the head unit 21 and the output shaft 45 starts to rotate in the forward direction (direction of arrow F in FIG. 9). As a result, the card 13 mounted on the mounting portion 14 of the tray 10 moves in the direction along the side surface 11 or the side surface 12 as shown by the arrow f in FIG. 9, and comes out of the insertion port 14b. The card 13 that has exited from the insertion port 14 b is fed into a card passage 70 formed in the card feeding portion 22 from a head side card slot 60 at a position adjacent to the head portion 21.

  The card 13 flows through the card passage 70 in the feeding direction (in the direction of arrow G in FIG. 9) by rollers 87 to 89 rotating by the power transmitted from the motor 18, and the card display changing device 3 is fed from the feeding-side card inlet / outlet 76. Is sent to. The card display changing device 3 changes the display of the information described on the recording surface of the card 13 sent from the detaching device 2, and then returns the card 13 to the sending card entrance / exit 76.

  The control device changes the energization state of the motor 18 at an appropriate timing such as when the card 13 is sent to the card display changing device 3 or when the display of the card 13 is changed. Is rotated in the opposite direction. As a result, the rollers 87 to 89 of the card feeding section 22 of the detaching apparatus 2 and the rollers 58 of the head section 21 start to rotate in the direction opposite to the rotating direction when the card 13 is removed. Therefore, when the card 13 is returned from the card display changing device 3 to the sending side card entrance / exit 76, the card 13 flows in the card passage 70 in the return direction (arrow R direction in FIG. 9) and reaches the head side card entrance / exit 60. .

  When the card 13 returns to the head side card entrance / exit 60, the card 13 is bitten between the roller 58 of the head portion 21 and the side surface 11 or the side surface 12 of the tray 10. Here, as described above, the roller 58 of the head portion 21 rotates in the direction opposite to that when the card 13 is removed from the mounting portion 14 as indicated by an arrow S in FIG.

  For this reason, the card 13 is inserted into the mounting portion 14 by the roller 58 from the insertion port 14b as indicated by the arrow s. When it is confirmed that the card 13 is inserted into the mounting portion 14, the control device rotates the eccentric cam 112 in the reverse direction (in the direction of arrow Z in FIG. 9) until the eccentric portion 115 is detected by the sensor 118. As a result, the display changing device 1 is pulled by the spring 64, rotates around the support shaft 26 in a direction away from the tray 10 (in the direction of arrow C in FIG. 9), and returns to the original posture. As a result, the display changing device 1 completes a series of operations, and prepares for the removal of the card 13 from the next tray 10 and the display changing operation.

  As described above, the display change device 1 according to the present embodiment rotates the eccentric cam 112 to move the main body 25 and the main body 25 comes into surface contact with the side surface 11 and the side surface 12 of the tray 10 to prevent rotation. When possible, the eccentric cam 112 is moved away from the pressure receiving wall 23e together with the moving portion 102. For this reason, the display change device 1 according to the present embodiment is mounted on the mounting portion 14 by causing the head portion 21 to abut on the side surface 11 and the side surface 12 even if the tray 10 is slightly deviated from a predetermined standard. The card 13 can be removed. More specifically, the display changing device 1 rotates the eccentric cam 112 until the eccentric portion 115 contacts the pressure receiving wall 23e, and changes the display from the position where the head portion 21 arrives when the main body portion 25 is rotated. If the side surface 11 and the side surface 12 of the tray 10 arrive in the area on the apparatus 1 side, the card 13 can be attached to and detached from the mounting portion 14.

  Further, as described above, when the head unit 21 comes into contact with the side surface 11 or the side surface 12 of the tray 10, the display change device 1 receives pressure together with the moving unit 102 while the eccentric cam 112 presses the pressure receiving wall 23 e of the main body unit 25. Move away from wall 23e. Therefore, the head portion 21 can press the side surfaces 11 and 12 of the tray 10 and the card 13 with an appropriate pressing force for removing and attaching the card 13 regardless of the size and shape of the tray 10, and these are excessively pressed. Or the pressure is not sufficient. Therefore, the display change device 1 hardly causes problems such as the roller 58 of the head portion 21 slipping with respect to the card 13 or the card 13 or the roller 58 is excessively worn or damaged.

  Since the display changing device 1 is an integration of the detaching device 2 for detaching the card 13 and the card display changing device 3 for changing the display of the card 13, a series of operations can be performed smoothly. Moreover, since the display change apparatus 1 employs a so-called rewrite card as the card 13, the card 13 can be used repeatedly several hundred times. Furthermore, according to the display change device 1 of the present embodiment, the card 13 can be prevented from being worn or damaged, and the card 13 can be used as long as the display can be changed. Therefore, the display change device 1 of the present embodiment has a low running cost and can suppress the amount of waste to a minimum as compared with the case where a disposable card is adopted.

  Although the example which employ | adopted the rewrite card | curd as the card | curd 13 was illustrated in the said embodiment, this invention is not limited to this, For example, it can also be set as the structure which employ | adopted the card | curd which cannot change display. More specifically, instead of replacing the card display changing device 3 with respect to the detaching device 2, the display changing device 1 supplies a discarding means for discarding a disposable card removed from the tray 10 by the detaching device 2, or a card, for example. It is also possible to adopt a configuration in which a card supply means to be used, a card recording means for recording predetermined information on the card supplied from the feeder, and the like are connected. In such a configuration, although the card cannot be reused, the card on which the predetermined information is written can be smoothly and accurately removed from the tray 10.

The above-described display change device 1 sends the card 13 removed by the detachable device 2 to the card display change device 3, rewrites the display information, returns it to the detachable device 2, and returns it to the mounting portion 14 of the tray 10. The present invention recommends a configuration such as the display change device 150 shown in FIG.

More specifically, the display change device 150 includes a main body 151 and a position adjustment mechanism 100 formed in an appropriate shape such as a skeleton structure or a box shape similar to the detachment device 2 of the display change device 1 described above. And is arranged along the conveying device 15a. Similar to the display change device 1, the display change device 150 is supported so as to be close to and away from the transport device 15a around the support shaft 26. Instead of connecting and integrating the card display change device 3 as in the display change device 1, the display change device 150 is displayed at the position corresponding to the head portion 21 as shown by hatching in FIG. It is set as the structure which provided. The display change head unit 152 can rewrite the display information of the card 13 in the same manner as that contained in the card display change device 3.

  When the tray 10 with the card 13 to be changed in display arrives at a position adjacent to the main body 151, the display change device 150 performs the same operation as the case of the display change device 1 in the position adjustment mechanism unit 100. The change head unit 152 is pressed against the recording surface of the card 13 attached to the side surface 11 or the side surface 12 of the tray 10.

  More specifically, when the tray 10 arrives at a position adjacent to the main body 151, the control device (not shown) of the display changing device 150 moves the transport device 15a as shown by an arrow A in FIG. While stopping, the motor 113 of the position adjustment mechanism part 100 is started, and the eccentric cam 112 is rotated. As a result, the main body 151 is pushed by the eccentric cam 112, and the display change head 152 is pushed against the card 13 as shown in FIG. Thereafter, when the eccentric cam 112 further rotates, the reaction force Fr acting on the eccentric cam 112 from the main body 151 side becomes larger than the force Fa attracting the eccentric cam 112 to the main body 151 side by the spring 64. Thereby, the eccentric cam 112 escapes in the direction away from the main body 151 as shown in FIG. As a result, the display change head portion 152 of the main body portion 151 is brought into contact with the card 13 with an appropriate pressing force.

  When the eccentric portion 115 of the eccentric cam 112 comes closest to the main body portion 151 as shown in FIG. 12B, the control means stops energization to the motor 113. Thereafter, the control unit activates the transport device 15a and moves the tray 10 relative to the display change head unit 152 as indicated by an arrow B in FIG. The control means moves the tray 10 in the direction of the arrow C opposite to the arrow B as necessary. That is, the control unit moves the tray 10 relative to the display change head unit 152 according to the printing (printing) capability of the display change head unit 152, and the tray 10 along the display change head unit 152 if necessary. Is reciprocated. Thereby, the display information of the card 13 is sequentially rewritten by the display change head unit 152.

  When the rewriting of the card 13 is completed, the control means reversely rotates the eccentric cam 112 as indicated by an arrow Z in FIG. 12C, and separates the main body 151 and the display change head 152 from the tray 10. Thereby, the display information changing operation for the series of cards 13 by the display changing device 150 is completed.

The display change device 150 described above is provided with the display change head portion 152 having a function corresponding to the card display change device 3 at a position corresponding to the head portion 21 of the display change device 1. Is a compact configuration. Further, since the display change device 150 can change the display information of the card 13 without performing operations such as the removal of the card 13 and the return of the card 13, the display information can be changed smoothly and quickly.

  Further, since the display change device 150 described above includes the position adjustment mechanism unit 100 similar to that of the display change device 1, the tray 10 having a slight variation in size and shape with respect to a predetermined standard is supplied. Even in this case, the display change head unit 152 can be abutted against the card 13 mounted on the tray 10 with an appropriate pressing force. Therefore, the display change device 150 displays display information such as a contact failure between the display change head unit 152 and the card 13 and a printing failure or an erasing failure caused by the display change head unit 152 being excessively abutted against the card 13. There is no change defect.

Each of the display change devices 1 and 150 described above changes display information by bringing a display change device (not shown) built in the card display change device 3 and a display change head unit 152 into close contact with each other. However, the present invention is not limited to this, and may be configured as a display change device 170 shown in FIG. 13, for example.

  More specifically, the display change device 170 has substantially the same structure as the display change device 150 described above, but an information communication device 171 (reader / writer) is attached instead of the display change head unit 152. Is different. When the display change device 170 is employed, a card 172 as shown in FIG. 13 is employed instead of the card 13 described above.

  The information communication device 171 is a device capable of transmitting data including predetermined information to be displayed on the card 172 or composite information including the information. The card 172 includes a data processing unit 173 and a display unit 175 as shown in FIG. The card 172 can transmit and receive data to and from the data processing unit 173 in a non-contact state with respect to the information communication device 171, and as a result, a part or all of the information accumulated in the data processing unit 173 is displayed on the display unit. 175 can be displayed.

  More specifically, the data processing unit 173 is configured by what is called a so-called RFID (Radio Frequency Identification) tag. The data processing unit 173 includes a communication unit such as an antenna unit 173a for data communication with the information communication device 171 and a storage unit such as an IC (integrated circuit) chip 173b. It is configured to include data processing means such as a processor, radio wave rectifying means, and the like.

  When the antenna unit 173a receives a radio wave from the information communication device 171, the data processing unit 173 generates an electromotive force by a resonance action such as electromagnetic induction. With this electromotive force, the IC chip 173b is activated, and data transmitted from the information communication device 171 side is stored. At this time, the data stored in the IC chip 173b is transmitted to the information communication device 171 side as necessary. That is, the data processing unit 173 can transmit and receive data using an electromotive force generated by a radio wave transmitted from the information communication device 171.

The data processing unit 173 can hold, for example, personal data relating to the type and amount of the medicine stored in the tray 10, the dispensing date of this medicine and the patient receiving the medication in the IC chip 173 b . Here, as personal data to be held in the IC chip 173b , for example, the name and sex of the patient assigned to the tray 10 to which the card 172 is attached, age, ward, hospital room number, address, telephone number, ID number, insurance card What is appropriately selected by the user of the medication system 5 from various data such as number, medication history, medical history, medical condition, height, weight, prescription, injection note, doctor's or pharmacist's findings, precautions for medication, etc. Adopted.

The display unit 175 is configured by a display device called a so-called cholesteric liquid crystal or electronic paper. The display unit 175 is electrically connected to the data processing unit 173, and can display part or all of the data stored in the IC chip 173b . The display unit 175 requires power when writing or erasing information to be displayed on the display surface. Once the information is displayed on the display surface, the information can be continuously displayed without supplying power. It is a thing. Therefore, the display unit 175 can write and erase display information displayed on the display surface by using an electromotive force generated by electromagnetic induction or the like when the information communication device 171 and the data processing unit 173 are used, for example. .

Further, as shown in FIG. 13B, the card 172 also transmits and receives data by transmitting radio waves from the information communication terminal 180 prepared separately from the information communication device 171 toward the data processing unit 173, Update of data stored in the IC chip 173b of the data processing unit 173, update of display information on the display unit 175, and the like can be performed. As the information communication terminal 180, for example, an information portable terminal such as a PDA (Personal Digital Assistants) or an information management device can be employed. Therefore, for example, if an information communication terminal 180 such as a PDA is carried by a doctor, a nurse, or the like, data is transmitted to and received from the data processing unit 173 of the card 172 mounted on the tray 10 using the information communication terminal 180. Data processing such as reading the prescription of the medicine stored in the tray 10 stored in the IC chip 173b and the injection note of the injection, and writing the prescription history of the medicine in the IC chip 173b can be performed. Accordingly, the card 172 displays the stored information of the IC chip 173b on the display unit 175, and in addition to the function as a label indicating the information of the medicine stored in the tray 10 and the patient receiving this medicine. It also has a function as an information storage medium.

  As described above, if a data management system that transmits / receives and updates data using the card 172 and the information communication device 180 is employed, paper media such as prescriptions and injections required in the prior art can be reduced. it can. Further, with the above-described configuration, it is possible to reduce the number of paper media or to provide a configuration that does not include a printer for printing on the paper media. Therefore, if the above-described data management system is adopted, a device adopting the display change device 170 can have a simple configuration and a running cost can be suppressed.

  In addition, by using a paper medium such as the above-mentioned prescriptions and injection notes and a data management system constructed by combining the card 172 and the information communication device 180, it is possible to prevent mistakes such as prescribing a medicine by mistake. It can suppress more reliably. When constructing a data management system as described above, it is desirable to provide sufficient security for personal information held on the card 172. For example, reading and writing of information such as prescriptions and injection notes that are particularly important It is desirable to have a configuration that prompts the user to input a password when entering the password, or a configuration that specifies an operator using a biometric authentication system or the like.

  Here, when there is a need to sufficiently protect privacy and personal information, such as when there is a patient who does not want to be known to be hospitalized, information displayed on the display unit 175 of the card 172, IC It is desirable to erase the information stored in the chip 173b when it becomes unnecessary. Therefore, based on such knowledge, when the card 172 and the information communication device 180 are used in combination as described above, the information displayed on the display unit 175 of the card 172 or the information stored in the IC chip 173b as necessary. It is also possible to adopt a configuration in which a part or all of the stored information can be erased. More specifically, for example, when information displayed on the display unit 175 or information stored in the IC chip 173b is no longer necessary, for example, after the completion of medication, Such information may be erased by transmitting a signal. According to this configuration, sufficient consideration can be given to the privacy of the patient and the protection of personal information.

  As described above, the information communication device 171 can exchange data with the card 172 in a non-contact state. However, the information communication device 171 is connected to the card 172 attached to the tray 10 that comes to a position adjacent to the display change device 170. It is possible to reliably transmit predetermined data to the card 172 mounted on the other tray 10 to prevent erroneous data transmission or data theft, or to operate other devices installed in hospitals or the like. The output is suppressed to prevent disturbing radio waves. Therefore, in order to change the display information on the card 172 to information based on the data transmitted from the information communication device 171, it is necessary to bring the information communication device 171 and the card 172 close to each other.

  Therefore, when the tray 10 arrives at a position adjacent to this, the display change device 170 operates the position adjustment mechanism unit 100 in the same manner as the display change devices 1 and 150 described above to bring the information communication device 171 and the card 172 close to each other. In this state, the display information on the card 172 is changed by transmitting predetermined data from the information communication device 171.

  The display change device 170 described above is configured to change the display information of the card 172 by transmitting and receiving data between the information communication device 171 and the card 172. Changes can be made more smoothly and quickly.

  Further, the above-described display change device 170 needs to bring the information communication device 171 and the card 172 close to each other when the display information of the card 172 is changed. There is no need to bring the card 172 into close contact. Therefore, the display change device 170 can cope with a wider range of variations in the size and shape of the tray 10.

  Since the display change device 170 does not need to bring the information communication device 171 and the card 172 into close contact with each other, the tray 10 having a prescribed size and shape is supplied, and the eccentric portion 115 of the eccentric cam 112 is closest to the main body portion 151. In some cases, a certain amount of gap may be formed between the information communication device 171 and the card 172. With such a configuration, the information communication device 171 and the card 172 can be prevented from being damaged or damaged to a minimum.

  Note that the display change device 170 described above is a card in which the display change device 170 is mounted on the tray 10 in consideration of improvement in data transmission / reception accuracy between the information communication device 171 and the card 172, security issues, and the like. The position adjustment mechanism unit 100 is configured only when the data transmission / reception accuracy between the information communication device 171 and the card 172 is insufficient or when high transmission / reception accuracy is required. It is good also as a structure which operates. Further, when it is possible to solve the problem of accuracy of data transmission / reception between the information communication device 171 and the card 172, the security issue, etc., the configuration in which the display change device 170 is not tilted, that is, as shown in FIG. It is also possible to fix the display changing device 170 to another member such as a frame and not to provide the position adjusting mechanism 100.

  As described above, the card 172 capable of receiving predetermined information or predetermined data including the information and displaying a part or all of the data is mounted on the side surface of the tray 10 as a transported object. The change device 170 includes an information communication device 171 as a display change unit capable of transmitting predetermined information or predetermined data including the information to a card 172 mounted on a mounting portion provided on a side surface of the conveyed object. It is a thing. Therefore, according to the display change device 170, the display information displayed on the display unit 175 of the card 172 can be rewritten without bringing the information communication device 171 and the card 172 into contact with each other.

  Further, as described above, the card 172 includes a data processing unit 173 including a communication unit (antenna unit 173a) for data communication with the information communication device 171 and a storage unit (IC chip 173b), and the data processing. And a display unit 175 for displaying part or all of the data supplied via the unit 173. In such a configuration, necessary information can be stored in the storage unit in the IC chip 173b which is a storage unit of the data processing unit 173, and all or a part of the information stored in the IC chip 173b is stored in the display unit 175. Can be displayed. That is, with the above configuration, the card 172 can be used as a label for the tray 10 and also as a storage unit for storing various data.

  In the case of the above configuration, the data processing unit 173 is desirably provided with an RFID tag. According to such a configuration, the card 172 can be made compact, and a configuration excellent in data transmission / reception accuracy can be achieved.

  In addition, as described above, the display change device 170 uses the power generated by the resonance effect associated with data exchange with the communication means (antenna unit 173a) for data communication with the information communication device 171 to perform data It is desirable that the processing unit 173 operates. Further, it is desirable that the card 172 updates the display on the display unit 175 using the electric power generated by the resonance action described above. With this configuration, it is not necessary to provide a separate power source for updating the data stored in the data processing unit 173 and the display displayed on the display unit 175.

  As described above, it is desirable that the display surface of the display unit 175 is composed of cholesteric liquid crystal. According to such a configuration, it is not necessary to supply power to the card 172 in order to maintain the display of information on the display unit 175, and for example, power consumption can be suppressed as compared with the case where the display unit 175 uses a conventionally known nematic liquid crystal. .

  Next, the configuration of the display change device 1 shown in the above embodiment will be described more specifically, and an embodiment relating to a medication system provided with the display change device 1 will be described in detail with reference to the drawings. In the following description, the same parts as those in the above embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  In FIG. 14, 1 is the display change device 1 of the present embodiment. In the medication system 5 of the present embodiment, the display changing device 1 is installed in the tray discharge device 8 as shown in FIG. As shown in FIG. 15, the medication system 5 includes a tray supply device 6, a medicine dispensing device 7, and a tray discharge device 8. The dosing system 5 is suitable for prescription of drugs and medical materials (hereinafter simply referred to as drugs) called “regular prescription” performed in hospitals and the like, and prescription of drugs such as “extra prescription”. It is a system that can be used. Here, the regular prescription is a prescription performed to administer a predetermined drug to a person (recipient) who receives medication such as an inpatient. In the regular prescription, for example, at a predetermined time such as the night before the day when the medicine is to be prescribed, the medicine corresponding to the recipient is stored in the tray 10 determined for each recipient, and the tray 10 is stored in the ward. This method is performed by classifying the information into a mounting shelf or the like determined for each predetermined block, and dispensing each ward (block). The temporary prescription is a prescription for a patient (recipient) whose content of prescription should be changed due to, for example, a sudden change in condition. In extraordinary prescriptions, drugs are often prescribed for each patient on the day of dosing.

  The tray supply device 6 is a device that pays out a tray 10 containing a medicine toward a transport path 9 provided at an adjacent position. The tray 10 is assigned to each recipient who receives medication in the above-mentioned regular prescription or temporary prescription. In the tray 10, a card 13 in which information related to a medicine and a recipient of the medicine is written in an appropriate form such as a character, a symbol, a barcode or the like is attached to a mounting portion 14 on one of the side surfaces 11 and 12. . As described above, the card 13 includes the ward name 13a and the room name 13b of the patient assigned to the tray 10, the medication execution date 13c, the patient name 13d, the furigana 13e, the ID number 13f, the number of times the card 13 is rewritten 13g, and the like. Is marked. Therefore, the patient assigned to the tray 10 can be specified by referring to the card 13. Further, by referring to the number of times of rewriting 13g, it can be easily confirmed whether or not the card 13 has reached the service life limit. Furthermore, if the barcode 13h is read by a specific reader or the like, the patient's gender, age, address, telephone number, insurance card number, medication history, medical history, medical condition, height, weight, recorded via the barcode 13h, Appropriate data such as prescriptions, injection notes, findings of doctors and pharmacists, precautions for medication, etc. can be read out.

  The tray 10 is collected with the card 13 mounted after completion of the prescription, and is returned to the tray supply device 6. Further, when the card 13 mounted on the collected tray 10 has reached the end of its service life or when a new tray 10 is used, a new card 13 on which no information is written is placed on the side surfaces 11 and 12. After being inserted into one of the mounting portions 14, the tray supply device 6 is set.

  The tray 10 paid out from the tray supply device 6 is transferred to the transport path 9 arranged at a position adjacent to the tray supply device 6 and moves toward the medicine delivery device 7 side. Here, the conveyance path 9 is configured by a conventionally known conveyance device such as a belt conveyor or a roller conveyor, and the conveyance path 9 from the position adjacent to the tray supply device 6 in the flow direction of the tray 10 in the medication system 5. A series of flow paths connected to the tray discharge device 8 disposed downstream is formed.

  The medicine dispensing device 7 applies a predetermined amount of a predetermined amount of medicine to the tray 10 supplied from the tray supply device 6 based on an instruction such as a prescription corresponding to the recipient of the medicine assigned to the tray 10. This is a payout device. After a predetermined medicine is stored in the medicine dispensing device 7, the tray 10 is transported toward the tray discharge device 8 on a conveyor that constitutes the transport path 9.

  Here, as described above, the tray 10 is collected after the previous medication, and is set in the tray supply device 6 after being overlapped in an appropriate order.

Therefore, the card display changing device 3 takes in the card 13 sent from the card passage 70 from the entrance, rewrites the display information of the card 13 inside, and then from the sending card entrance 76 of the detaching device 2 to the card passage 70. Can be returned to.

Next, the operation of the display change device 1 which is a feature of the present invention will be described in detail with reference to the drawings. The display change device 1 of this example operates the position adjustment mechanism 100 as described in the above embodiment and operates the actuator 29 to the tray 10 that has arrived at the position adjacent to the detaching device 2. The head unit 21 is brought close to the card 13 and the card 13 is removed and the display is changed.

  More specifically, the control device (not shown) of the display change device 1 is placed at a position adjacent to the head portion 21 of the display change device 1 by the card presence / absence detection sensor 49 as shown in FIG. Is detected, the motor 113 of the position adjustment mechanism unit 100 is activated to rotate the eccentric cam 112 in the direction of arrow A as described in the above embodiment. As a result, the pressure receiving wall 23e of the main body 25 is pressed by the contour portion of the eccentric cam 112 as shown in FIG. 7, and the display changing device 1 is tilted toward the tray 10 side.

  When the eccentric cam 112 further rotates from the state shown in FIG. 7, the display changing device 1 further tilts toward the tray 10 as shown in FIG. 8, and the roller 58 of the head portion 21 is attached to the side surface 11 or the side surface 12 of the tray 10. The card 13 is pressed against the current card 13. Here, as shown in FIG. 19, the head unit 21 is configured such that a pedestal 44 to which an output shaft 45 that supports a roller 58 is attached can swing around a swinging shaft 53. The spring 55 is energized by the spring 55. Therefore, when the head portion 21 is pressed against the side surface 11 or the side surface 12 of the tray 10, the output shaft 45 tilts along the side surface 11 or the side surface 12 together with the pedestal 44, and the roller 58 firmly contacts the surface of the card 13. It becomes a state.

  Further, when the head portion 21 comes into surface contact with the side surface 11 or the side surface 12 of the tray 10, the pressing portion 62 b of the tray pressing piece 62 attached to the front surface 25 a side of the main body portion 21 is connected to the mounting portion 14 of the tray 10. It strikes against the protrusion 17 provided on the left side. The protruding portion 17 is pressed by the tray pressing piece 62 in the direction from the outside to the inside of the tray 10. Therefore, when the head portion 21 is abutted against the tray 10, the insertion port 14 b is opened, and the card 13 is freely attached to and detached from the mounting portion 14 by sliding the card 13 with respect to the side surface 11 and the side surface 12. It will be ready.

  Here, as described above, the motor 113 continues to operate until the sensor 117 detects that the eccentric portion 115 has reached the pressure receiving wall 23e side. Therefore, the motor 113 continues to operate even when the roller 58 of the head portion 21 is in contact with the card 13 as shown in FIG. When the operation of the motor 113 is continued in the state shown in FIG. 8, the reaction force Fr acting on the eccentric cam 112 side is gradually increased by pressing the pressure receiving wall 23 e by the eccentric cam 112. When the reaction force Fr becomes larger than the pulling force Fa that pulls the moving part 102 to which the eccentric cam 112 is attached to the pressure receiving wall 23e, the eccentric cam 112 is separated from the pressure receiving wall 23e together with the moving part 102 as shown in FIG. Run away in the direction. As a result, the roller 58 is pressed against the card 13 with an appropriate pressing force, so that the roller 58 and the card 13 are in close contact with each other and the card 13 is not rotated even if the eccentric cam 112 continues to rotate. Excessive load does not work.

  As shown in FIG. 9, when the sensor 117 detects that the eccentric portion 115 of the eccentric cam 112 has arrived at the pressure receiving wall 23e side, the control means stops energizing the motor 113 of the position adjusting mechanism portion 100, Energization of the motor 18 on the main body 25 side is started. Thereby, the power of the motor 18 is transmitted to the head 21 side, and the output shaft 45 of the head portion 21 and the roller 58 attached thereto start to rotate.

  When the roller 58 rotates, the card 13 that is in surface contact with the roller 58 slides in the direction along the side surface 11 or the side surface 12 and exits from the insertion port 14b. The card 13 that has slipped out of the insertion port 14 b is fed into the card passage 70 via the head-side card inlet / outlet 60 that is open at a position adjacent to the head portion 21.

  As shown in FIG. 1, when the card 13 is sent to the card passage 70 side and the detection signal of the card 13 by the card position detection sensor 28 provided on the back side of the head portion 21 is interrupted, that is, the end portion of the card 13 is the card. When the position detection sensor 28 is passed through the installation position, the control means operates the actuator 29. As a result, the head portion 21 is retracted toward the main body portion 25 as shown by an arrow X in FIG. 21B, and is completely separated from the side surface 11 and the side surface 12 of the tray 10 as shown in FIG. . Therefore, while the card 13 is fed in the card path 70, even if the roller 58 of the head portion 21 continues to rotate by operating the motor 18, friction does not occur between the roller 58 and the tray 10, and the roller 58 Does not wear.

  When the card 13 is sent into the card passage 70 as described above, the card 13 receives power from the rollers 87 to 89 arranged along the card passage 70 and is sent to the sending side entrance 76 side to display the card. It is sent to the changing device 3. When the card 13 is sent to the card display change device 3, the control means operates the card display change device 3 to change the display of information written on the card 13.

  When the display change of the card 13 is completed in the card display changing device 3, the card 13 is returned to the feeding side entrance 76 provided in the main body 25 of the detaching device 2. At the same time, or when the card 13 is sent to the card display changing device 3, the control means switches the energized state of the motor 18 and reverses the rotation of the output shaft 18a of the motor 18. Thereby, the rollers 87 to 89 of the card feeding unit 22 and the rollers 58 and 58 of the head unit 21 rotate in the opposite direction to the rotation direction when the card 13 is removed from the tray 10. Therefore, the card 13 returned from the card display changing device 3 flows in the card passage 70 toward the head portion 21 side, and protrudes outside the main body portion 25 from the head side card entrance 60 as shown in FIG. To do.

  When the card 13 protrudes from the head side card entrance / exit 60 and is detected by the card position detection sensor 28, the control means stops energization to the actuator 29 and extends the telescopic shaft 29a to the original state, that is, the front 25a side. Return to the state. Accordingly, the card 13 is sandwiched between the rollers 58 and 58 of the head portion 21 and the side surface 11 or the side surface 12 of the tray 10 as shown in FIG. As a result, the power of the rollers 58 and 58 is transmitted to the card 13 and the card 13 is inserted into the mounting portion 14 of the tray 10.

  When the card presence / absence detection sensor 49 detects that the card 13 is received in the mounting portion 14, the control unit stops energization of the motor 18 provided in the main body portion 25. Thereafter, the control means starts energizing the motor 113 of the position adjustment mechanism unit 100 and rotates the eccentric cam 112 in the direction of arrow Z in FIG. Accordingly, the eccentric portion 115 of the eccentric cam 112 gradually moves away from the pressure receiving wall 23e, and the main body portion 25 is pulled away from the tray 10 by the spring 64 attached to the pedestal portion 33b.

  When the card 13 is removed and the display is changed as described above, the control means operates the handling device 15b disposed above the transport device 15a, and moves the tray 10 from the transport device 15a to the front of the tray discharge device 8. It is transferred to the placed mounting shelf 54. Thereby, the display change device 1 completes a series of prescription operations for the tray 10.

  Next, the operation of the medication system 5 of this embodiment will be described in detail with reference to the flowchart shown in FIG. When the medication system 5 is activated, the control device of the medication system 5 waits for input of prescription order data based on an instruction from a doctor or the like (step 1). Here, the prescription order data is the name and sex of the patient to be prescribed, age, ward, room number, address, telephone number, ID number, insurance card number, medication history, medical history, medical condition, height, weight, prescription This refers to data selected as appropriate by doctors, such as injection notes, findings of doctors and pharmacists, and precautions for medication.

  When the prescription order data is input in step 1, the tray 10 is paid out from the tray supply device 6 to the transport device 15 and is transported downstream by the transport device 15. On the other hand, the control device operates the medicine dispensing apparatus 7 based on pre-input prescription order data, and prepares the medicine. When preparation of the medicine is completed in the medicine dispensing device 7 and the tray 10 reaches the medicine dispensing device 7, the medicine can be put into the tray 10.

When the preparation for inputting the medicine is completed in the medicine dispensing device 7, the medicine is put into the tray 10. Along with this, the control unit, the drug dispensing device 7 or than this activates the printer over not shown located downstream side, prescription or injection prescription pharmaceutical agents are put into the tray 10, the doctor or pharmacist findings during dosing Data such as precautions are printed, and this printed matter is put into the tray 10 together with the medicine. This completes the operation of putting the medicine into the tray 10 (step 2).

  When the medicine loading operation is completed in step 2, the tray 10 is sent out from the medicine dispensing device 7 toward the tray discharging device 8. When the tray 10 reaches the tray discharge device 8, the display changing device 1 operates according to the above-described procedure, and the card 13 mounted on the side surface 11 or the side surface 12 of the tray 10 is rewritten (step 3). When the rewriting of the card 13 is completed in step 3, the handling device 15 b of the tray discharge device 8 is activated, and the tray 10 is transferred to the mounting shelf 54 prepared in front of the tray discharge device 8. Thereby, the payout operation of the tray 10 is completed (step 4).

  When the mounting of the tray 10 on the mounting shelf 54 is completed in step 4, the medicine stored in the tray 10 is compared with the printed matter stored in the tray 10 in step 5, and the medicine is stored in the tray 10. A drug audit operation is performed to confirm whether or not the drug has been paid out correctly. Here, the medicine auditing operation is one or more appropriately selected from a visual confirmation method by a doctor, a pharmacist, a nurse, etc., a mechanical confirmation method using a tag or barcode attached to the medicine, etc. By the method.

  If the medicine is not properly dispensed in step 5, the tray 10 is removed from the mounting shelf 54, and the medicine dispensing operation by the series of controls described above is performed again. On the other hand, if the medicine is correctly dispensed to the tray 10 in step 5, the tray 10 is transported to the ward or the like with the tray 10 mounted on the mounting shelf 54. The tray 10 conveyed by the mounting shelf 54 is delivered to a doctor or a nurse in charge of the patient described on the card 13 based on the card 13 attached thereto. The doctor or nurse performs the medication or injection of the medicine contained in the tray 10 based on the printed matter such as a prescription or an injection note accommodated in the tray 10.

  As described above, the display change device 1 employed in the present embodiment rotates the main body 25 by rotating the eccentric cam 112 and brings the head 21 into contact with the card 13 or the tray 10. It is. In the display change device 1, the reaction force Fr acting when the head portion 21 hits the card 13 or the tray 10 and the eccentric cam 112 presses the pressure receiving wall 23 e receives the moving portion 102 to which the eccentric cam 112 is attached. The eccentric cam 112 is configured to move away from the pressure receiving wall 23d together with the moving portion 102 on the condition that it is larger than the pulling force Fa attracted to the wall 23e side. Therefore, in this embodiment, even if trays 10 of different sizes and standards are supplied in a mixed manner, the rollers 58 and 58 of the head portion 21 are appropriately pressed against the side surfaces 11 and 12 of each tray 10 and the card 13. It is possible to make surface contact with pressure.

  Furthermore, in the display change device 1 of the present embodiment, the pedestal 44 that supports the output shaft 45 of the head portion 21 is supported so as to be swingable. Therefore, when the head unit 21 is abutted against the card 13 or the tray 10, the display changing device 1 is inclined so that the output shaft 45 is along the side surfaces 11 and 12 of the tray 10, and the outer peripheral surfaces of the rollers 58 and 58 are the card. 13 is surely in surface contact. Therefore, the display changing device 1 can bring the roller 58 of the head portion 21 into contact with an appropriate pressing force even when used in a situation where the trays 10 having slightly different sizes and shapes are mixed. The roller 58 does not slip at the time of attachment / detachment of the roller, and the roller 58 is not pressed with an excessive pressing force. Therefore, the display change device 1 of the present embodiment can reliably remove the card 13, and the rollers 58 and 58 and the card 13 are not easily worn.

  The display change device 1 shown in the above-described embodiment and examples is arranged such that the detachable device 2 and the card display change device 3 are horizontal in the installed state, but the present invention is limited to this. For example, as shown in FIG. 22, the display changing device 1 may be swingably supported by a shaft body 99 extending in the longitudinal direction. With this configuration, even if the trays 10 having the inclined side surfaces 11 and 12 are sequentially supplied, the entire display changing device 1 is inclined along the side surfaces 11 and 12 of each tray 10, and the rollers 58 and 58 are moved to the card 13. And can be brought into surface contact with the side surfaces 11 and 12 reliably.

  Further, the display change device 1 of the present embodiment is configured such that the actuator 29 is connected to the frame member 35 constituting the head portion 21 via the connecting rod 29b, and the actuator 29 operates the frame member 35 by operating the actuator 29. The rollers 58 and 58 of the head portion 21 can be moved close to and away from the side surfaces 11 and 12 of the tray 10 and the card 13 by rotating around the input shaft 43. That is, the display change device 1 can adjust the distance between the rollers 58 and 58 and the side surfaces 11 and 12 and the card 13 according to the operating state of the actuator 29. Therefore, the display changing device 1 keeps the head portion 21 away from the side surfaces 11 and 12 and the card 13 while waiting for the card 13 to be removed as shown in FIG. Etc. can be prevented from being worn or damaged.

  As described above, according to the display change device 1 of the present embodiment, the card 13 or the like is hardly worn or damaged. Therefore, in the medication system 5 of the present embodiment, the card 13 can be used as long as the display can be changed. Therefore, according to the medication system 5 of the present embodiment, it is possible to minimize the maintenance frequency such as replacement of the card 13 that has been worn or damaged, and to suppress the running cost.

  The display changing device 1 according to the present embodiment is a tray pressing piece that is attached to a position adjacent to the head portion 21 on the front surface 25a side of the main body portion 25 when the head portion 21 abuts against the side surfaces 11 and 12 of the tray 10. The pressing portion 62b of 62 pushes the protruding portion 17 that closes the insertion port 14b of the tray 10, and the insertion port 14b is opened. Therefore, the display changing device 1 can open the insertion port 14b simply by bringing the head portion 21 into surface contact with the side surfaces 11 and 12 of the tray 10, and can smoothly remove and insert the card 13.

  In any of the display change devices 1 shown in the above-described embodiments and examples, the position adjusting mechanism 100 presses the pressure receiving wall 23e of the detaching device 2 by the eccentric cam 112, but the present invention is limited to this. For example, instead of providing the eccentric cam 112 and the motor 113, a configuration similar to the actuator 29 provided for adjusting the position of the head portion 21 may be attached to the moving portion 102.

  Moreover, in the said Example, although the structure which has arrange | positioned the display change apparatus 1 to the tray discharge apparatus 8 distribute | arranged to the most downstream side of the medication system 5 was illustrated, this invention is not limited to this, From this May also be installed on the tray supply device 6 and the medicine dispensing device 7 arranged on the upstream side, and are separately provided in the middle of the conveyance path 9 connecting the tray supply device 6, the medicine dispensing device 7 and the tray discharge device 8. It is good also as a structure arranged independently.

  Moreover, although the medication system 5 of the said Example was equipped with the display change apparatus 1 shown in the said embodiment, this invention is not limited to this, It replaces with the display change apparatus 1 and is above-mentioned. The display change device 150 and the display change device 170 may be adopted.

  More specifically, when the display change device 150 is employed instead of the display change device 1 described above, the tray 10 arrives at a position facing the display head unit 152 as in the case where the display change device 1 is employed. At that time, the tray 10 is temporarily stopped. Then, the position adjustment mechanism unit 100 is operated to press the head unit 152 against the card 13 mounted on the tray 10 as shown in FIGS. Thereafter, the transport device 15a is operated, and the tray 10 is moved relative to the display head unit 152 as indicated by arrows B and C in FIG. Or writing information on the display surface.

  When the display change device 170 is employed instead of the display change device 1 described above, the display on the display unit 175 of the card 172 can be changed in the same manner as when the display change devices 1 and 150 are employed. . More specifically, when the display change device 170 is employed, the tray 10 arrives at a position facing the information communication device 171 mounted on the main body 151 as in the case where the display change device 1 is employed. The tray 10 is temporarily stopped. Then, the position adjustment mechanism unit 100 is operated to bring the card 172 mounted on the tray 10 and the information communication device 171 closer to each other. Thereafter, the control device activates the information communication device 171, and the patient's name and sex, age, ward, room number, address, telephone number, ID number, insurance card number, medication history, medical history, medical condition, height, weight, The patient's personal data assigned to the tray 10 such as prescription, injection note, doctor's and pharmacist's findings, precautions for medication, etc. is transmitted and received. As a result, personal data is stored in the data processing unit 173 of the card 172, and all or part of the personal data is displayed on the display unit 175 in an appropriate form such as a character, a figure, a barcode, or the like.

  As described above, when the display change device 170 is employed, predetermined data can be displayed on the display unit 175 and various data can be stored in the data processing unit 173. Therefore, as described above, when the display change device 170 is adopted, data is transmitted by transmitting radio waves from the information communication terminal 180 prepared separately from the information communication device 171 toward the data processing unit 173 of the card 172. The personal data stored in the processing unit 173 can be called up or the personal data can be updated.

  More specifically, when the display change device 170 is employed, for example, personal data stored in the card 172 can be displayed on the information communication terminal 180 in the form shown in FIG. Further, if an appropriate program or the like is incorporated in the information communication terminal 180, an audit system similar to, for example, a prescription or an injection note can be constructed. Therefore, when the display changing device 170 is adopted in the medication system 5, an audit system constructed by the card 172 and the information communication terminal 180 and a printed matter such as a prescription or an injection note accommodated in the tray 10 in the operation procedure shown in FIG. Thus, the reliability of the medication system 5 can be improved. In addition, if an audit system constructed by the card 172 or the information communication terminal 180 is employed instead of the printed matter such as the prescription and the injection note, the amount of paper medium used in the medication system 5 can be reduced, and devices such as a printer can be used. Can be omitted. Therefore, if the display change device 170 is employed, the running cost and manufacturing cost of the medication system 5 can be reduced.

  In addition, when the display change device 170 is adopted, a part of the patient information stored in the IC chip 173b of the card 172 or a part of the information displayed on the display unit 175 by communication with the information communication terminal 180 or It is also possible to erase all at a desired timing. More specifically, from the viewpoint of patient privacy and protection of personal information, after the medicine stored in the tray 10 is dispensed, the display information on the card 172 and the information stored in the IC chip 173b are deleted. Is desirable. Therefore, based on such knowledge, the display changing device 170 operates the information communication terminal 180 at the time when the medication is completed to transmit radio waves and signals toward the card 172, and displays the information displayed on the card 172 and the IC chip 173b. The stored information may be erased.

  More specifically, the display change device 170 has a function of monitoring the medication state based on information read into the information communication terminal 180 by communication between the card 172 and the information communication terminal 180, for example (FIG. 25A). When the completion of the medication is confirmed, a display prompting the user to select whether or not to erase the display information and stored information on the card 172 is displayed as shown in FIG. Based on this, the display information and stored information of the card 172 can be erased. According to this configuration, sufficient consideration can be given to the protection of the patient's personal information and stored information.
