  The first slide member 66 includes a first engagement portion 66 a that engages with the protrusion 24 of the paper feed cover 16 and a second engagement portion 66 b that engages with the second slide member 68.

  The first urging member 72 has one end attached to the panel member 18 and the other end attached to the first slide member 66. The first urging member 72 urges the first slide member 66 in the + Z direction. In addition, the 1st biasing member 72 is comprised as a spring member in a present Example.

  Further, when the paper feed cover 16 is open in the printer 10, the first slide member 66 is urged in the + Z direction by the first urging member 72, and the first engagement portion 66 a is the panel member 18. A state of projecting from an opening 78 (see FIG. 7A) provided on the upper surface (see FIGS. 2, 6B, and 7A) is obtained.

  When the paper feed cover 16 is closed in the printer 10, the first engagement portion 66 a of the first slide member 66 and the protrusion 24 of the paper feed cover 16 are engaged, and the first slide member 66 is a first biasing member 72. It slides in the −Z direction against the urging force (see FIGS. 4B and 7B).

  Next, referring to FIG. 4 (A), FIG. 4 (B), FIG. 6 (A), FIG. 6 (B), FIG. 8 (A) and FIG. The force member 74 will be described. The 2nd slide member 68 is comprised as a flat member extended in the X-axis direction as a whole. In the second slide member 68, the upper end portion and the lower end portion near the panel member 18 are provided with slide portions 68a that protrude in the + Z direction and the −Z direction, respectively, and extend in the X axis direction (FIG. 6). (See (B), FIG. 8 (A) and FIG. 9 (A)).

  The panel member 18 is provided with a pair of guide rails 18a (see FIG. 6B) that extend in the X-axis direction and face each other with a gap in the Z-axis direction. The second slide member 68 is configured such that the slide portion 68a is received by the pair of guide rails 18a of the panel member 18 and is slidable in the X-axis direction.

It is attached to the end. The third urging member 76 urges the third slide member 70 in the + X direction. Specifically, the third urging member 76 causes the third slide member 70 to be in contact with the fourth engagement portion 82 of the second slide member 68 and the fifth engagement portion 88 of the third slide member 70. 2 is biased toward the slide member 68. In addition, the 2nd biasing member 74 is comprised as a spring member in a present Example.

■■■ Regarding opening / closing restrictions in opening / closing control means ■■■■■■■■■■■■■■■■■
Next, the opening / closing restriction of the discharge port cover 20 in the opening / closing restriction means 64 will be described with reference to FIGS. 10A to 11C in order. For convenience of explanation, explanations of the first position X1 to the fourth position X4 and the first state to the third state will be made before and after.

  FIG. 10A shows a state of the opening / closing regulating means 64 in a state where the paper feed cover 16 and the discharge port cover 20 are closed with respect to the apparatus main body 12 (see FIG. 4B). In this state, the first slide member 66 is engaged with the protrusion 24 of the paper feed cover 16 and is displaced in the −Z direction. For this reason, the second slide member 68 is displaced in the + X direction by the first slide member 66.

  For this reason, the first hook engaging portion 86 of the second slide member 68 is also displaced to the + X direction side, which is a direction away from the hook 84 provided in the center region in the width direction (X axis direction) of the discharge port cover 20. Yes. Note that the position of the first hook engaging portion 86 that is separated from the hook 84 is defined as a second position X2.

  On the other hand, the third slide member 70 is biased toward the second slide member 68. For this reason, the second hook engaging portion 90 of the third slide member 70 is engaged with the hook 84, and the hook 84 is locked. For this reason, the 2nd hook engaging part 90 has controlled that the discharge port cover 20 rotates to the apparatus front side (-Y direction side).

  For this reason, the opening / closing restricting means 64 restricts the panel member 18 from opening the discharge port cover 20 because the hook 84 is in a restrained state (locked state). This state is referred to as a first state in the opening / closing regulating means 64. The first state of the opening / closing regulating means 64 is the closed state of the discharge port cover 20 by engaging with the hook 84 of the discharge port cover 20 when the paper feed cover 16 is closed and the discharge port cover 20 is closed. This is a state in which the transition from the open state to the open state is prevented.

  Further, the position at which the second hook engaging portion 90 of the third slide member 70 places the hook 84 in a restrained state (locked state) and restricts the discharge port cover 20 to the closed state is a third position X3 (see FIG. 10A). ).

  As described above, since the transition to the open state of the discharge port cover 20 is prevented when the paper feed cover 16 and the discharge port cover 20 are closed, the closed discharge port cover 20 is easily opened by its own weight. The discharge port cover 20 can be prevented from being opened carelessly, thereby preventing dust and foreign matter from entering the inside of the apparatus.

  Next, FIG. 10B shows one state of the opening / closing regulating means 64 in the process of opening the paper feed cover 16 from the state where the paper feed cover 16 and the discharge port cover 20 are closed. When the paper feed cover 16 is opened with respect to the housing 14 by the user, the engagement between the protrusion 24 of the paper feed cover 16 and the first engagement portion 66a of the first slide member 66 is released. For this reason, the first slide member 66 is displaced in the + Z direction by the urging force of the first urging member 72, and the second slide member 68 engaged with the first slide member 66 is also the second urging member 74. It is displaced in the −X direction by the urging force.

  Further, since the fourth engagement portion 82 and the fifth engagement portion 88 are in the engaged state, the third slide member 70 moves in the −X direction in accordance with the displacement of the second slide member 68 in the −X direction. Displace. For this reason, the second hook engaging portion 90 of the third slide member 70 is also displaced in the −X direction from the third position X3. Therefore, the engagement state between the second hook engaging portion 90 and the hook 84 of the third slide member 70 is canceled. As a result, the locked state of the discharge port cover 20 is released.

Next, when the paper feed cover 16 is further opened and the second slide member 68 is further displaced in the −X direction side from the state of FIG. 10B as shown in FIG. The hook engaging portion 86 comes into contact with the hook 84 and presses the hook 84 in the −Y direction (FIG. 11A). For this reason, the discharge port cover 20 rotates to the apparatus front side (-Y direction side). By rotating the discharge port cover 20 toward the front side of the apparatus, the discharge port cover 20 is opened with respect to the panel member 18, and the discharge port 62 is opened (see FIG. 4A).
In this state, the lock state release position with respect to the hook 84 of the second hook engaging portion 90 of the third slide member 70 is defined as a fourth position X4 (see FIG. 10C).

  FIG. 11A shows the state of the opening / closing regulating means 64 in which the paper feed cover 16 is open with respect to the housing 14. Specifically, the first slide member 66 is displaced in the + Z direction side, and the first engagement portion 66a protrudes from the opening 78. For this reason, the 2nd slide member 68 exists in the state most displaced to the -X direction side. The first hook engaging portion 86 is located at the position of the hook 84 when the discharge port cover 20 is closed in the X-axis direction.

  Therefore, in this state, when the user turns the discharge port cover 20 to close the panel member 18, the hook 84 contacts the first hook engaging portion 86. For this reason, since the 1st hook engaging part 86 regulates the displacement to the position in the state which the hook 84 closed, the discharge port cover 20 cannot be closed with respect to the panel member 18. FIG. A position where the second hook engaging portion 90 of the second slide member 68 prevents the hook 84 from moving to the locked position is defined as a first position X1.

  As described above, the opening / closing restricting means 64 restricts the discharge port cover 20 from being closed with respect to the panel member 18 when the paper feed cover 16 is open with respect to the housing 14. Since the transition from the open state to the closed state of the discharge port cover 20 is prevented when the paper supply cover 16 is opened and the discharge port cover 20 is opened, the paper supply cover 16 and the discharge port cover 20 are not related. In some cases (for example, when the paper feed cover 16 is a cover for the medium feeding port 28 and the discharge port cover 20 is a cover for the discharge port 62), only the discharge port cover 20 is closed and the apparatus is operated. Can be prevented from occurring (for example, paper jam).

  In the state where the paper feed cover 16 and the discharge port cover 20 are opened, the opening / closing regulating means 64 that engages with the hook 84 of the discharge port cover 20 and prevents the discharge port cover 20 from shifting from the open state to the closed state. This state is referred to as a second state.

  Next, in FIG. 11B, when the paper feed cover 16 is closed with respect to the housing 14, the protrusion 24 engages with the first engagement portion 66 a and the first slide member 66 is pushed in the −Z direction side. (See FIG. 4B). For this reason, the second slide member 68 engaged with the first slide member 66 is displaced in the + X direction. For this reason, the first hook engaging portion 86 moves from the first position X1 to the second position X2 that allows the hook 84 to move to the locked position in the X-axis direction.

  In this state, the third slide member 70 is urged toward the second slide member 68 by a third urging member 76 (see FIG. 4A). For this reason, the second hook engaging portion 90 is located at the third position X3 where the hook 84 is restrained. In this state, when the discharge port cover 20 is closed with respect to the panel member 18, the inclined surface formed on the tip end side of the hook 84 and the second hook engaging portion 90 come into contact with each other.

  As shown in FIG. 11C, when the user pushes the discharge port cover 20 further to the + Y direction side from the state of FIG. 11B, the third slide member 70 resists the urging force of the third urging member 76. Then, it slides in the −X direction along the inclined surface of the hook 84. At this time, the fifth engagement portion 88 of the third slide member 70 releases the engagement state with the fourth engagement portion 82 of the second slide member 68 and is separated from the fourth engagement portion 82.

  Then, when the discharge port cover 20 is further pushed in to the + Y direction side, the second hook engaging portion 90 gets over the inclined surface of the hook 84 and the hook 84 is in a restrained state (locked state) shown in FIG. And displace. For this reason, the discharge port cover 20 is locked by the opening / closing regulating means 64 provided in the panel member 18. When the second hook engaging portion 90 is displaced to the restrained state, the third slide member 70 is displaced in the + X direction side, and again, the fifth engaging portion 88 of the third slide member 70 and the second slide member 68 are displaced. The fourth engaging portion 82 is engaged.

  In addition, when the paper feed cover 16 is closed and the discharge port cover 20 is opened, the opening / closing regulating means that engages with the hook 84 of the discharge port cover 20 to allow the transition of the discharge port cover 20 from the open state to the closed state. This state of 64 is defined as a third state.

  As described above, when the paper feed cover 16 is closed and the discharge port cover 20 is opened, the transition from the open state to the closed state of the discharge port cover 20 is allowed. A suitable state, that is, a state in which the discharge port cover 20 is closed can be formed.

  Further, since the hook 84 is provided in the central region of the discharge port cover 20 in the width direction (X-axis direction), the opening / closing regulating means 64 is discharged in the central region of the discharge port cover 20 in the width direction (X-axis direction). The opening / closing of the outlet cover 20 can be restricted.

  That is, the opening / closing regulating means 64 is engaged with the discharge port cover 20 in the central region in the medium width direction (X-axis direction) that is a direction intersecting the medium discharge direction in the discharge port cover 20. Since the opening / closing is restricted, it is possible to prevent the one end of the discharge port cover 20 in the medium width direction (X-axis direction) from floating when the discharge port cover 20 is closed. Can be closed.

  As described above, the feeding cover 16 and the discharge port cover 20 in this embodiment are both closed by the panel member 18 that forms the front of the apparatus that constitutes the periphery of the housing 14. It can be closed with higher accuracy without depending on each other. Further, rattling in the closed state can be prevented, and the texture of the product can be prevented from being lowered. In addition, since the panel member 18 is also provided with an opening / closing regulating means 64 that regulates the opening / closing of the discharge port cover 20 according to the open / closed state of the paper feed cover 16, the opening / closing of the discharge port cover 20 is more firmly regulated. be able to.

  In addition, since the discharge port cover 20 is also opened by opening the paper feed cover 16, the user operation is simplified, and when the paper feed cover 16 and the discharge port cover 20 are related (for example, the paper feed cover 16 has a medium supply). (When the cover 28 is the cover 28 and the outlet cover 20 is the cover of the outlet 62), the occurrence of malfunctions (for example, paper jams) due to the operation of the apparatus with the outlet cover 20 closed is prevented. it can.

  Further, the protrusion 24 provided on the paper feed cover 16 for restricting the edge position on one side of the medium engages with the opening / closing restricting means 64 to switch the opening / closing restriction state of the discharge port cover 20. It is not necessary to separately provide a dedicated configuration for switching the restriction state of opening / closing of the outlet cover 20, and the configuration of the apparatus can be simplified and the cost can be reduced.

  Further, when the paper feed cover 16 is closed, the discharge port cover 20 is interposed via the first slide member 66 that is displaced along the direction (Z-axis direction) in which the paper feed cover 16 moves relative to the panel member 18. Since the opening / closing restriction state switching is performed, when the opening / closing restriction state switching of the discharge port cover 20 is performed, it is possible to prevent the paper feed cover 16 from receiving a force in the direction (X-axis direction) intersecting the opening / closing direction. .
