(Action / Effect)
In the medicine packaging apparatus 101 according to the present embodiment, the opening 21r of the cover body 21a is opened and closed by moving the movable part 27. By opening the opening part 21r of the cover part main body 21a, the display part can be formed on the packaging material 10 with the pen 24. On the other hand, when the pen 24 is not used, the pen tip 24a can be reliably protected by closing the opening 21r of the cover body 21a. Thereby, even if the powder of the medicine is flying, it is possible to prevent the powder of the medicine from adhering to the pen tip 24a, and thus it is possible to prevent the writing performance of the pen from being deteriorated. Further, when the user places the packaging material 10 on the medicine packaging device 101, the pen tip 24a can be prevented from coming into contact with the user's fingers or the packaging material 10.

  The movable part 27 opens and closes the opening 21r of the cover part main body 21a by moving along the cover part main body 21a. Therefore, the configuration for protecting the pen tip 24a can be reduced in size.

  As shown in the present embodiment, the at least one pen preferably includes a plurality of pens 24. The pen holding unit 23 holds the plurality of pens 24 so that the pen tips 24a of the plurality of pens 24 are arranged in a circumferential direction centered on a certain axis 90, and the cover is formed by the pen holding unit 23. It is preferable to collectively cover the pen nibs 24a of the plurality of pens 24 held. The drive mechanism selectively rotates the pen tip 24a of any one of the plurality of pens 24 held by the pen holder 23 by rotating the pen holder 23 about the axis 90. By moving the first drive mechanism that moves to the position corresponding to the opening 21r and the pen holding part 23 with respect to the packaging material 10, the pen tip 24a at the position corresponding to the opening 21r is moved to the packaging material. A second drive mechanism that makes contact with or separates from 10 and a third drive mechanism that opens and closes the opening 21r by moving the movable portion 27 along the cover main body 21a. The mechanism and the third drive mechanism preferably include a common drive source. By adopting this configuration, for example, a combination of a plurality of pens 24 having different colors can be held in the pen holding unit 23. By linking the first drive mechanism and the second drive mechanism, the pen holder 24 is rotated to select the desired pen 24 from the plurality of pens 24, and then the pen tip 24a of the selected pen 24 is wrapped. Since it can contact | abut to the material 10, a display part can be formed in the packaging material 10 with the selected desired color. Since the first drive mechanism that rotates the pen holding unit 23 and the third drive mechanism that opens and closes the opening 21r include a common drive source, the number of drive sources can be reduced as the entire medicine packaging device 101. The structure can be simplified.

  The gear 44 shown in FIG. 38 corresponds to the first drive mechanism. The stepping motor 42 shown in FIG. 8 corresponds to a second drive mechanism. The pen holder socket 30 corresponds to a third drive mechanism.

  The stepping motor 41 shown in FIG. 8 corresponds to a common drive source for the first drive mechanism and the third drive mechanism. The rotational motion caused by the stepping motor 41 is transmitted as the rotational motion of the pen holder socket 30 through the gear 43 and further through the gear 44 of the pen unit 21 shown in FIG. The protrusion 30b provided on the outer peripheral surface of the pen holder socket 30 is engaged with the protrusion 27b provided on the inner periphery of the movable part 27, and the protrusion 30b presses the protrusion 27b, whereby the movable part 27 is engaged. Can be rotated. The movable part 27 is biased by a spring so as to rotate in a certain direction. Since the protrusion 30b suppresses the free rotation of the protrusion 27b, the movable portion 27 can be maintained in a desired posture.

  As shown in the present embodiment, it is preferable that the movable portion 27 is rotatable about the axis 90 with respect to the cover portion main body 21a. By adopting this configuration, the movable portion 27 is rotated by the same center line as the rotation center line of the pen holding portion 23. Therefore, it is easy to transmit the rotational movement from the drive source, and the structure is simplified. Can be

  The mechanism of rotation of the pen holding part 23 and the movable part 27 will be described with reference to FIG. In FIG. 39, “rotation operation” represents a range of angles in which the pen holding unit 23 rotates with a straight line. The five circles displayed as “rotation stop positions” mean that there are five angular positions at which the pen holding unit 23 can stop rotating. “Shutter” refers to the movable portion 27. The numbers 1 to 4 surrounded by a circle are displayed as “pens”, meaning that each of the four types of pens is positioned at a position corresponding to the opening 21r. For example, when the rotation angle is 0 °, the first pen 24 is positioned at a position corresponding to the opening 21r. When the rotation angle is 90 °, the second pen 24 is positioned at a position corresponding to the opening 21r. When the rotation angle is 180 °, the third pen 24 is positioned at a position corresponding to the opening 21r. When the rotation angle is 270 °, the fourth pen 24 is positioned at a position corresponding to the opening 21r. Since the pen 24 positioned at the position corresponding to the opening 21r is already in a position close to the packaging material 10, the pen holding portion 23 is displaced by the second drive mechanism, so that the pen tip 24a is placed on the packaging material 10. It can be made to contact.

  As shown in FIG. 12, the pen holding unit 23 and the movable unit 27 rotate around the axis 90 in a first rotation direction 94 and a second rotation direction 95 opposite to the first rotation direction 94. It is possible to move. A reference angular position 97 is set in the pen holder 23. In FIG. 39, the position at the rotation angle of 0 ° is the reference angle position 97. In FIG. 39, proceeding to the right represents rotation in the direction of the first rotation direction 94. In FIG. 39, proceeding to the left represents rotation in the direction of the second rotation direction 95. When the pen holding unit 23 is rotated in the first rotation direction 94 upstream of the first rotation direction 94 with respect to the reference angular position 97, the movable unit 27 is rotated from the closed position to the open position. . This means the case of rotating from −123 ° to 0 °. When the pen holding unit 23 is rotated in the second rotation direction 95 upstream of the first rotation direction 94 with respect to the reference angular position 97, the movable unit 27 is rotated from the open position to the closed position. . This means the case of rotating from 0 ° to −123 °. The “upstream side of the first rotation direction 94” indicates a position on the left side in FIG. The pen holding unit 23 is rotated in the first rotation direction 94 and the second rotation direction 95 on the downstream side of the first rotation direction 94 with respect to the reference angular position 97, so that the movable unit 27 is moved to the open position. In a certain state, the pen tip 24a of any one of the plurality of pens 24 held by the pen holding unit 23 is selectively moved to a position corresponding to the opening 21r. The “downstream side in the first rotation direction 94” indicates a position on the right side in FIG. By adopting this configuration, the pen holding unit 23 and the movable unit 27 can efficiently open and close the movable unit 27 and switch the pen 24 by utilizing the rotational motion around the common axis 90.

  As shown in the present embodiment, the movable portion 27 is maintained in the open position by being urged in the first rotation direction 94, and the pen holding portion 23 is moved to the reference angle position 97 for the first time. When rotating in the second rotation direction 95 on the upstream side of the movement direction 94, it is preferable that the second rotation direction 95 is pressed to rotate from the open position to the closed position. By adopting this configuration, the movable portion 27 is urged in the first rotation direction 94. Therefore, the movable portion 27 is rotated in the second rotation direction 95 with a large force to overcome this urging, or this urging force is applied. The movable part 27 can be rotated to a desired position by selecting whether to rotate in the first rotation direction 94 by using it. Thus, the opening portion 21r can be opened and closed by the movable portion 27 with a simple configuration.

  Here, the movable portion 27 is biased in the first rotation direction 94 to be maintained in the open position when there is no load, and is closed from the open position when rotated in the second rotation direction 95. Although it demonstrated as what rotates to a position, this is an example to the last and the reverse structure may be sufficient.

  As shown in the present embodiment, the movable portion 27 includes a pressed portion, the medicine packaging device 101 includes a pressing portion that rotates together with the pen holding portion 23, and the pressed portion is The pen holding unit 23 is preferably pressed by the pressing unit when the pen holding unit 23 is rotated in the second rotation direction 95 on the upstream side of the first rotation direction 94 with respect to the reference angular position. In the present embodiment, the protrusion 30 b provided on the outer peripheral surface of the pen holding part socket 30 corresponds to the “pressing part”, and the protrusion 27 b provided on the inner periphery of the movable part 27 corresponds to the “pressed part”. . By adopting this configuration, it is possible to reliably transmit the rotational motion with a simple structure.
