Thereby, in the platen support member 91, the position of the platen roller 32 that the support plate 912 supports rotatably, the position of the engaging claw 916 that engages with the latch portion 92, and further the position of the contact portion 914 Can be defined in advance.

  The support plate 912 is fixed so as to rotatably support the shaft of the platen roller 32 interposed between the both side walls at the ends of the both side walls of the writing table unit 40 on the thermal head 34 side. In FIG. 8, the position of the axis of the platen roller supported by the support plate 912 is indicated by reference numeral 32.

  An abutting portion 914 is provided continuously to the support plate 912 at a position facing the ejecting portion 93 with the planar portion of the abutting portion 914 facing each other.

  The engaging claw 916 protrudes downward from the lower portion of the abutting portion 914, engages with the latch portion 92 at a position where the writing table portion 40 is closed, and the ejecting portion 93 opens the writing table portion 40. Regulate slide movement to. The outer surface on the closing direction side of the engaging claw 916 is a tapered surface 916a.

  The latch portion 92 is attached to the apparatus main body 20 side so as to be rotatable around a shaft portion 922 extending in the axial direction of the platen roller 32 or the longitudinal direction of the thermal head 34. The latch portion 92 is disposed in a state of being biased to the engagement position with the engagement claw 916. The outer surface on the front end side of the latch portion 92 is a curved surface 92a. The shaft portion 922 is rotatably provided by operating the release switch 99 shown in FIG. As the shaft portion 922 rotates, the latch portion 92 is displaced downward about the shaft portion 922 and moves from the engagement position with the engagement claw 916 to the engagement release position. For example, a bar that moves up and down in conjunction with the slide of the release switch 99 is arranged so as to extend in the vertical direction, and a shaft portion 922 is linked to the vertical movement of the bar at the tip of the bar. You may make it the structure attached so that it might rotate.

  The ejecting portion 93 protrudes from the apparatus main body 20 side toward the abutting portion 914 with a plunger portion 932 provided so as to be movable back and forth toward the abutting portion 914 of the platen support member 91 and the plunger portion 932. And a biasing member 934 for biasing.

  The plunger portion 932 is attached so as to be movable in the axial direction, that is, in the forward / backward direction while penetrating the flange portion 26 of the apparatus main body 20. The plunger portion 932 is provided with a flange-like restriction stopper that protrudes from the outer periphery of the plunger portion 932 so as to restrict the movement range of the plunger portion 932 itself in the forward / backward direction (axial direction). This restriction stopper prevents the plunger portion 932 from coming off from the flange portion 26 of the apparatus main body 20. A biasing member 934 that is a coil spring is externally inserted between the flange portion and the one end portion 932a that contacts the contact portion 914. The plunger portion 932 causes the one end portion 932a to move backward. In the locked state moved to the flange portion 26 side, the other end portion 932b protrudes from the flange portion 26 in the reverse direction (retreat side).

  The other end portion 932b protruding in the reverse direction from the flange portion 26 due to the movement of the plunger portion 932 itself presses the movable terminal 982 of the open / close detection switch 98 that detects opening / closing of the lighting table portion 40 to the contact terminal on the switch body side. Make contact. Thereby, when both terminals are made conductive (switch-on state), the open / close detection switch 98 detects that the lighting table unit 40 is closed. If the lock is released, the one end 932a of the plunger portion 932 is moved to the lighting table portion 40 side by the urging member 934, and the other end portion 932b is also moved accordingly, and is separated from the open / close detection switch 98. . As a result, the pressure on the movable terminal 982 is released, and the movable terminal 982 is separated from the contact terminal on the switch body side and the conductive state is released (switched off).

  Next, the setting of the continuous paper LP on the medical measurement apparatus 10 will be described. 9 is a cross-sectional view showing a state in which the lighting table unit is opened in FIG. 6, and FIG. 10 is a cross-sectional view showing a state in which the writing table unit is opened in FIG.

  When there is no continuous paper (folded paper in this case) LP in the paper storage unit 70 in the state shown in FIG. 1, or when the continuous paper LP is set in the recording unit when the writing table unit 40 is closed, the release switch 99 (see FIG. 4) is operated. Then, as the shaft portion 922 rotates, the latch portion 92 moves backward from the engagement position with the engagement claw 916, and the engagement state with the engagement claw 916, that is, the lighting table portion 40 in the closed state is locked. It is released (see FIGS. 7 and 10). By releasing the engagement state, the plunger portion 932 disposed at the retracted position against the urging force of the urging member 934 by the engagement of the latch portion 92 and the engaging claw 916 is Due to the urging force, it moves from the retracted position to the writing table unit 40 side. As a result, the one end portion 932a of the plunger portion 932 presses the abutting portion 914, and as a result, the writing table portion 40 is moved to the other side of the apparatus main body 20 (left side in each drawing) as shown in FIG. The inside of the concave portion 23 is exposed to the outside. At this time, the platen roller 32 moves in the moving direction (one side) of the writing table unit 40 and is separated from the thermal head 34. Further, the tension guide member 82 is separated from the transport guide portion 84. When the writing table unit 40 is not sufficiently moved, the operator moves the writing table unit 40 to the other side.

  In this way, since the concave portion 23 is exposed to the outside when the writing table portion 40 is opened, the continuous paper LP can be easily put into the paper accommodating portion 70 disposed at the bottom of the concave portion 23 from the device top surface 12 side. Can supply. In addition, with the writing table unit 40 open, one end of the continuous paper LP is pulled upward so that the surface of the conveyance guide unit 84, specifically, the curved surfaces of the first and second guide units 842 and 844 are curved. And between the guide ribs 86. Subsequently, one end is pulled upward to be positioned up to a position exceeding the device top surface 12 or near the device top surface 12.

  Then, the lighting table unit 40 is moved so as to be in a closed state. That is, one end surface of the writing table unit 40 is moved to the thermal head 34 side in the upper part 20a of the apparatus main body 20. Then, the platen roller 32 sandwiches the continuous paper LP with the thermal head 34 configured to come into contact with each other while being pressed (see FIG. 6). In the same manner, the tension guide member 82 presses the continuous paper LP disposed so as to be bridged between the first guide portion 842 and the second guide portion 844, and the first guide portion 842 and the second guide member 82. Arranged between the guide portions 844. As a result, the tension guide member 82, together with the conveyance guide portion 84, positions the continuous paper LP under tension on the continuous paper LP on the conveyance path below the recording portion. At the same time, the platen support member 91 also moves together with the writing table unit 40, and the tapered surface 916 a of the engaging claw 916 slides on the curved surface 92 a of the latch unit 92. The contact portion 914 moves the plunger portion 932 back toward the flange portion 26 against the urging force of the urging member 934, and the other end portion 932 b of the plunger portion 932 is a movable terminal 982 of the open / close detection switch 98. Is pressed (see FIGS. 7 and 8).

  When the engaging claw 916 is engaged with the latch portion 92, the writing table portion 40 is locked in the closed state, and at the same time, the terminals of the open / close detection switch 98 are electrically connected to each other to indicate that the lighting state is closed. The medical measurement apparatus 10 itself can detect the closed state of the writing table unit 40.

As described above, the medical measuring apparatus 10 supports both ends of the platen roller 32 and is fixed to the writing table unit 40 to attach the platen roller 32 to the writing table unit 40, and the apparatus main body 20 side. A latch portion 92 that can be engaged with the platen support member 91 when the platen roller 32 is positioned at a nip portion N1 (also referred to as a “nip position”, which corresponds to a “nip position”); When the lock is released by releasing the engagement between the platen support member 91 and the platen support member 91, the platen support member 91 is pressed by the plunger portion (extrusion member) 932 that moves to the platen roller side, so that the nip portion (position that can be held) And an ejecting portion 93 that moves to one side.

That is, since the platen support member 91 has a structure in which the support plate 912 that supports the platen roller 32 and the engaging claw 916 that engages and locks the latch portion 92 are integrated, the platen roller 32 is attached to the thermal head. 34 can be suitably locked and held at a desired printing position (nip portion N1, which is the nip portion) in contact with. Therefore, the recording position of biological information, that is, the printing position can be stabilized.

  Further, the plunger portion 932 of the eject portion 93 is a rod-shaped material, and when the one end portion 932a is pressed by the platen support member 91 and the platen roller 32 is positioned at the nip portion N1, the platen roller 932 is moved by the movement of the other end portion 932b. It has an open / close detection switch (sensor) 98 for detecting that the roller 32 is positioned at the nip portion N1. That is, since the movable terminal 982 of the opening / closing detection switch 98 is moved by the movement of the plunger portion 932 of the ejection portion 93 and the opening / closing detection switch 98 is turned on / off, the opening / closing detection switch 98 detects opening / closing. Compared with a configuration having a mechanism separately, the number of parts can be reduced and a simple configuration can be achieved.

  Further, the tension guide member 82 for separating the platen roller 32 from the thermal head 34 and for applying tension to the continuous paper LP at the time of recording (printing) is attached to the writing table unit 40 side, thereby the conveyance guide unit 84. And are separated. As a result, it is easy to put a hand in the recording unit (between the platen roller 32 and the thermal head 34) and the conveyance path (between the tension guide member 82 and the conveyance guide unit 84). It is easy to feed paper to the section and the conveyance path.

  The medical measurement apparatus 10 according to the present embodiment is a medical measurement apparatus that prints biometric information such as an electrocardiogram measured on a recording paper LP as an electrocardiogram waveform.

The writing table 42 is preferably flat. Further, the writing table unit 40 may be provided so as to be slidable via a rail unit 25 extending horizontally with respect to the apparatus main body 20.

As described above, according to the medical measurement apparatus 10, the recording paper can be easily and satisfactorily set by moving the writing table unit 40 in one side in the horizontal direction without complicating the apparatus configuration. Can print stably. Therefore, even in the case of the medical measurement apparatus 10 in which the display 50 is frequently arranged on the apparatus top surface 12 during use, when the continuous paper LP is set in the sheet storage unit 70 of the apparatus main body 20, the apparatus top The continuous paper LP can be set in the recording portion and the conveyance path and the continuous paper can be set in the concave portion 23 by merely sliding the writing table portion 40 to the side without interfering with the display 50 on the surface 12. . In use, the continuous paper LP on which the biological information is recorded is discharged from the paper discharge port 14 of the apparatus top surface 12 onto the writing table 42, where it is handwritten.

  Further, in the present embodiment, the recording paper LP comes into contact with the first surface of the recording paper LP in the conveyance path of the recording paper LP up to the nip portion (position where clamping is possible) N1 between the thermal head 34 and the platen roller 32. And a tension guide member 82 that is provided below the first guide portion 842 and guides the recording paper LP in contact with the second surface of the recording paper LP in the transport path. In addition, the first guide portion 842 and the tension guide member 82 are such that the recording paper LP protrudes to the first surface side by contact with the tension guide member 82 and to the second surface side by contact with the first guide portion. It was arranged on the apparatus main body 20 and the writing table part (moving body) 40 so as to project. Below the tension guide member 82, the recording paper is placed in contact with the first surface of the recording paper LP in the conveyance path of the recording paper LP that is disposed in the apparatus main body 20 and can be held between the print head and the platen roller. A second guide portion for guiding the LP is further provided. The tension guide member 82 is disposed between the first guide portion 842 and the second guide portion 844, and the recording paper LP projects to the first surface side by contact with the tension guide member 82, and the first guide portion 842. And it protrudes to the 2nd surface side by contact with the 2nd guide part 844.

  That is, the first guide portion 842 that contacts the first surface of the continuous paper LP in the transport path from the paper storage portion 70 to the recording portion and guides the continuous paper LP, and the second guide portion below the second guide portion 842. 844, and a tension guide member 82 is disposed between the first guide portion 842 and the second guide portion 844, and abuts against the second surface of the recording paper in the transport path to guide the recording paper. I tried to do it. Then, the first continuous paper is projected to the first surface side by contact with the tension guide member 82 and is projected to the second surface side by contact with the first and second guide portions 842 and 844. The second guide portions 842 and 844 and the tension guide member 82 are arranged.

  Thus, when the writing table unit 40 is closed, the first and second guide units 842 and 844 and the tension guide member 82 positioned between the first and second guide units 842 and 844 are zigzag (or A conveying path (so-called meandering shape) (so-called three-point roller type path) is formed. By doing in this way, the continuous paper LP pulled by the platen roller 32 can obtain tension in the entire conveyance path, and the bending of the continuous paper LP in the conveyance path can be reduced.
