  Further, as shown in FIG. 9, a plurality of bearings 68 are provided on the back surface of the medium supply port cover 24 at intervals in the apparatus width direction. The bearing 68 is provided at a position corresponding to the position of the hinge member 62 provided in the apparatus main body 12 in the apparatus width direction.

<<< About Hinge Member >>>
Next, referring to FIGS. 10 to 12, a hinge member attaching portion 70 is provided at the rear side end portion of the apparatus main body 12. As will be described later, the hinge member attaching portion 70 is provided with an urging means attaching portion 12c and a hook engaging portion 12d. The hinge member 62 is attached to the hinge member attaching portion 70 so as to be slidable in the direction including the vertical direction component, that is, in the apparatus height direction. The hinge member 62 will be described based on the posture attached to the apparatus main body 12.

  Biasing means 72 is provided between the hinge member 62 and the apparatus main body 12. The biasing means 72 is configured as a compression coil spring as an example. As shown in FIG. 11, a biasing means mounting portion 62 a is provided on the front side of the hinge member 62 in the apparatus depth direction. The urging means attaching portion 62a is formed in a pin shape as an example, and one end of the urging means 72 is inserted.

  The other end of the urging means 72 is engaged with the urging means attaching portion 12 c provided on the hinge member attaching portion 70. Here, the urging force of the urging means 72 urges the hinge member 62 in the hinge member mounting portion 70 in the direction including the vertical direction component, for example, in the apparatus height direction lower side.

  Referring to FIG. 12, a pair of rotating shaft parts 62 b, hooks 62 c, and spring members 74 are provided on the rear side of the hinge member 62 in the apparatus depth direction. The rotation shaft part 62b protrudes from the end of the hinge member 62 on the upper side in the apparatus height direction to the rear side in the apparatus depth direction. A rotation shaft 62d protrudes from the ends of the pair of rotation shaft portions 62b in directions opposite to each other.

  The rotation shaft 62 d is inserted into the bearing 68 of the medium supply port cover 24. Note that the pair of rotating shaft portions 62b facing each other has elasticity. When the rotation shaft 62 d is inserted into the bearing 68 and a predetermined external force is applied to the medium supply port cover 24, the pair of rotation shaft portions 62 b are deformed in directions away from each other and rotate from the bearing 68. The moving shaft 62d comes out and the connection between the medium supply port cover 24 and the hinge member 62 is released. Thereby, damage to the medium supply port cover 24 or the hinge member 62 can be suppressed or avoided.

  Further, the hook 62 c is formed at the lower end portion of the hinge member 62. When the hinge member 62 slides and moves in the apparatus height direction in the hinge member attaching portion 70, the hook 62c comes into contact with or separates from the hook engaging portion 12d, and the range of sliding movement of the hinge member 62 in the apparatus height direction is thereby reached. Is stipulated.

  The spring member 74 is provided at the upper end portion of the hinge member 62, and the spring member 74 is disposed between the pair of rotating shaft portions 62b in the apparatus width direction. As an example, the spring member 74 is configured as a leaf spring, more specifically, a so-called bistable spring. The spring member 74 is in contact with the bearing 68 of the medium supply port cover 24. Further, the spring member 74 is biased in a direction in which the medium supply port cover 24 closes in a range where the medium supply port cover 24 is opened from a closed state to a predetermined opening angle, and the medium supply port cover 24 is further moved from the predetermined opening angle. In the opened range, the medium supply port cover 24 is biased in the opening direction.

  Hereinafter, the opening / closing operation of the medium supply port cover 24 will be described with reference to FIGS. 10 and 13 to 16. Referring to FIG. 10, when the medium supply port cover 24 is closed, the medium supply port cover 24 is also urged by the urging force of the urging means 72 that urges the hinge member 62 downward in the apparatus height direction. Is biased to the side. As a result, the medium supply port cover 24 is pulled toward the apparatus main body 12, so that the gap 76 between the rear side end 24 a of the medium supply port cover 24 and the housing 12 a of the apparatus main body 12 is reduced in the apparatus height direction. That is, when the medium supply port cover 24 is closed, the gap 76 is filled (see also FIG. 2).

  Here, as shown in FIG. 10, when the medium supply port cover 24 is closed, the hinge member 62 is configured to be hidden inside the medium supply port cover 24 and the housing 12a. Therefore, it is possible to improve the appearance of the printer 10 when the medium supply port cover 24 is closed.

  When the medium supply port cover 24 is closed, the hinge member 62 is urged downward in the apparatus height direction by the urging means 72, and the hook 62 c is a hook engaging portion provided in the apparatus main body 12. It is in a state separated from 12d.

  Further, as shown in FIG. 15, a closed position defining surface 68a, a cam surface 68b, and an open position defining surface 68c are formed on the outer peripheral surface of the bearing 68 of the medium supply port cover 24. When the medium supply port cover 24 is closed, the spring member 74 abuts the closed position defining surface 68a at a position below the rotation shaft 62d in the apparatus height direction, and biases the closed position defining surface 68a. doing. Therefore, the spring member 74 biases the medium supply port cover 24 in the direction in which the medium supply port cover 24 is closed.

  Next, as shown in FIG. 13, when the medium supply port cover 24 is opened from a closed state (see FIG. 10), the sliding surface 66 provided on the rear side end 24 a becomes the sliding surface of the apparatus main body 12. 64 is contacted. The medium supply port cover 24 opens while the sliding surface 66 slides with respect to the sliding surface 64. At this time, the spring member 74 changes the contact position with the bearing 68 along the cam surface 68b from the closed position defining surface 68a. Since the spring member 74 is biased in the radial direction of the bearing 68, rattling of the medium supply port cover 24 with respect to the hinge member 62 can be suppressed.

  When the sliding surface 66 abuts against the sliding surface 64, the abutting portion serves as a fulcrum, and the hinge member 62 is slid upward in the apparatus height direction against the urging force of the urging means 72. At this time, the hook 62c moves upward in the apparatus height direction and approaches the hook engaging portion 12d.

  Then, as shown in FIGS. 14 and 16, when the medium supply port cover 24 is further opened, the spring member 74 comes into contact with the open position defining surface 68c of the cam surface 68b. In this state, the spring member 74 biases the open position defining surface 68c. The biasing force of the spring member 74 acts in the direction in which the medium supply port cover 24 opens. When the contact position between the spring member 74 and the cam surface 68b is switched from the closed position defining surface 68a to the open position defining surface 68c, or from the open position defining surface 68c to the closed position defining surface 68a, the user feels a click feeling. Therefore, the operability in the opening / closing operation of the medium supply port cover 24 can be improved.

  Further, in this state, the hook 62c engages with the hook engaging portion 12d, so that the sliding movement of the hinge member 62 upward in the apparatus height direction is restricted.

  Here, the hinge member 62 is urged downward in the apparatus height direction by the urging means 72, but the sliding surface 66 is in contact with the sliding surface 64, and the apparatus height of the hinge member 62 is The downward displacement in the vertical direction is restricted. Therefore, the medium supply port cover 24 maintains a posture inclined toward the back side in the apparatus depth direction with respect to the apparatus main body 12. In this state, the medium supply port cover 24 may be configured to function as a medium support member that supports the medium inserted into the medium supply port 26 in an inclined posture.

  Further, in order to switch the medium supply port cover 24 from the open state to the closed state, the medium supply port cover 24 is rotated from the rear side in the apparatus depth direction toward the front side by a force greater than the urging force of the spring member 74. Can be closed.
