[0044] Embodiment 1

[0045] Hereinafter, the automatic opening mechanism of the opening and closing cover and the printing device provided with the same according to Embodiment 1 will be described based on Figures 1 to 9 The automatic opening mechanism of the opening and closing cover and the printing device provided with the same according to Embodiment 1 will be described in detail.

[0046] In the following description, as shown in each drawing, three axes orthogonal to each other are respectively set as an X axis, a Y axis, and a Z axis. The Z axis direction corresponds to the vertical direction, that is, the direction of the action of gravity. The X axis direction and the Y axis direction correspond to the horizontal direction. In each drawing, the direction indicated by the arrow of each of the three axes (X, Y, Z) is the + direction of each direction.

[0047] As shown in FIG. 1, the opening and closing cover 1 is provided with a cover body 2 and a cover hinge 3. The cover body 2 is provided with a cover opening 4. Figures 1 to 3As shown, the printing device 1 according to the present embodiment is provided with an automatic opening mechanism 3 of a cover. Figure 3 Further, the printing device 1 is provided with a carriage 15 having a print head 65 that performs printing on a medium P, and that moves in a direction intersecting the transport direction of the medium P. Figure 2 is a state in which the cover 5 on the front side (+Y direction) of the printing device 1 is open, and further indicates a state in which a discharge tray 7 housed inside the device is pulled out. The discharge tray 7 that receives a medium P (hereinafter also referred to as "printout P") is configured to be operable by opening the cover 5. Further, a feeding cassette (omitted from the drawing) that houses a print medium can also be configured to be operable.

[0048] Further, the printing device 1 is a multifunction peripheral in which the inkjet printer 2 is located on the lower side, and the scanning unit 4 is provided on the upper side. Further, the cover 5 is disposed in a position adjacent to an ink tank 12 of the printing device 1. The ink tank 12 is capable of being filled with ink.

[0049] As shown in Figures 4 to 7 , in the present embodiment, the automatic opening mechanism 3 of the cover is provided with: a lever 11 that is rotatable via a rotation fulcrum 9; a locking portion 13 located at one end of the lever 11, that locks and maintains the closed state of the cover 5 that is subjected to a force F in the opening direction; and a power receiving portion 17 located at the other end of the lever 11, that receives the power of the carriage 15 that moves in the horizontal direction by coming into contact with the carriage 15. Figure 1 , Figure 8 ) of the cover 5. Figure 7

[0050] Further, the lever 11 is configured to rotate by the carriage 15 coming into contact with and pushing against the power receiving portion 17, and to release the maintenance of the closed state of the cover 5 by the locking portion 13.

[0051] Hereinafter, each component will be described in detail.

[0052] Lever of Automatic Opening Mechanism

[0053] In the present embodiment, as shown in Figures 4 to 6 , the lever 11 is elongated in the Y-axis direction that becomes the horizontal direction.

[0054] The locking portion 13 that is locked by the locked portion 18 of the cover 5 in the closed state is provided at one end of the lever 11. Figures 2 to 4 , Figure 6 Further, the power receiving portion 17 that receives the power of the carriage 15 that moves in the horizontal direction is provided at the other end of the lever 11. Figure 6 ​In the figure, the state in which the locking portion 13 of the lever 11 is disengaged from the locked portion 18 of the shutter 5 is shown. The locking portion 13 is formed in a convex curved surface shape in which the -X direction is the protruding direction, and is formed integrally with a locking portion main body 20 made of resin that extends in the Y axis direction. The locking portion 13 is provided on the side surface of the front end portion of the locking portion main body 20 in the +Y direction.

[0055] In addition, on the other end of the lever 11, a power receiving portion 17 that receives the power of the carriage 15 that moves is provided. In the present embodiment, this power receiving portion 17 is constituted by a sliding portion 19 that is pushed by the carriage 15 and slides. The sliding portion 19 is constituted by two portions 19a, 19b whose bottom surfaces are guided by two guide grooves 22, 24 (see FIG. 2) of the frame 30, respectively. Figure 5 ) The two portions 19a, 19b of the sliding portion 19 are integrally linked, and move integrally in the moving direction of the carriage 15, that is, the X direction.

[0056] The sliding portion 19a guided by the guide groove 22 constitutes the power receiving portion 17.

[0057] In the present embodiment, the sliding portion 19b guided by the guide groove 24 is linked to the locking portion main body 20 via a metal power transmission shaft 26. One end 6( Figure 6 ) of the power transmission shaft 26 is integrally linked and fixed to the base end portion 10 of the locking portion main body 20, and the other end 8 is linked in a non-fixed state in which it is inserted into a recessed portion 28 of the sliding portion 19b and contacts the inner surface of the recessed portion 28.

[0058] When the sliding portion 19a is pushed by the carriage 15 and the integral sliding portion 19b moves in the -X direction, the other end 8 of the power transmission shaft 26 moves in a state in which it contacts the inner surface of the recessed portion 28. Due to this, the lever 11 is able to rotate with respect to the rotation fulcrum 9. That is, the linear movement of the carriage 15 in the horizontal direction is converted into rotational movement of the lever 11 and is transmitted.

[0059] Rotation structure of lever of automatic opening mechanism

[0060] The lever 11 is rotatably installed in a horizontal plane on a rotation fulcrum shaft 58 that constitutes the rotation fulcrum 9. The rotation fulcrum 9 is constituted by the shaft center of the rotation fulcrum shaft 58. In the present embodiment, the rotation fulcrum shaft 58 is fixed in an orientation in which it extends in the up-down direction on the lower plate 14 and the upper plate 16 that are device configuration members.

[0061] The locking portion main body 20 of the lever 11 is positioned on the upper surface 32 of the upper plate 16, and the bottom of the base end portion 10 is rotatably linked to the rotation fulcrum shaft 58. A through hole 34( Figure 4), the protrusion 36 of the locking portion main body 20 is set to enter the through-hole 34 in a through state. The through-hole 34 is formed in a size and shape that enables the locking portion main body 20 to rotate around the rotational fulcrum 9 on the base end portion 10 side.

[0062] A torsion coil spring 38 is provided between the lower plate 14 and the upper plate 16 Figure 4 ), one end 40 of the torsion coil spring 38 is locked to the protrusion 36 of the locking portion main body 20. Thus, the locking portion main body 20 is configured to rotate in a direction in which the locking portion 13 and the locked portion 18 of the shutter 5 are locked, by receiving an elastic force of the torsion coil spring 38.

[0063] In addition, as shown in Figure 7 In the present embodiment, the sliding portion 19a has a contact protrusion 21 that contacts the carriage 15, and the carriage 15 is provided with a contact recess 23 at a position that contacts the contact protrusion 21. When the sliding portion 19a of the lever 11 is pushed by the carriage 15, the sliding portion 19a becomes a state in which the contact protrusion 21 enters the contact recess 23, and the sliding portion 19a easily moves integrally with the carriage 15.

[0064] In addition, as shown in Figure 8 In the present embodiment, the shutter 5 is configured to have a self-weight moment on the opening side. Specifically, a position of a center of gravity G of the shutter 5 is set to open by the self-weight with respect to a fulcrum 42 of an opening and closing operation thereof.

[0065] That is, the force F in the opening direction is generated by the self-weight of the shutter 5, and thus the shutter 5 is configured to automatically open by the action of the self-weight if the shutter 5 releases a closed state thereof.

[0066] Further, the force F in the opening direction is not limited to the configuration using the self-weight moment. For example, the force F in the opening direction can be applied using the elasticity of a spring.

[0067] In addition, as shown in Figure 9 In the present embodiment, a sensor 25 that detects an opening and closing state of the shutter 5 is provided. Here, the sensor 25 is configured by an action tab 27 provided to an inner surface of the shutter 5, and a detection tab 29 provided to a device configuration member of the printing device 1 in a state of being pressed in an extending direction.

[0068] Figure 9 (A) of FIG. 17 corresponds to a state in which the sensor 25 is detected to be OFF. That is, since the action tab 27 is not pressed into the detection tab 29, the sensor 25 is in a state in which the shutter 5 is detected to be open. Further, as a range in which the sensor 25 detects the shutter 5 to be open, an angle is set in which even if the opening of the shutter 5 is stopped in the middle, the discharged printed matter is not blocked. Here, the angle is set to 70 degrees.

[0069] Figure 9 (B) corresponds to the detection of the sensor 25 being in an ON state. That is, since the acting piece 27 presses into the detecting piece 29, the sensor 25 is in a state where it detects that the shutter 5 is closed.

[0070] Further, in the present embodiment, the operation to release the maintenance of the closed state of the shutter 5 is controlled to be executed after the main switch of the printing device 1 is turned ON and before the operation of printing is started. It is configured that the control section shown in the drawing executes the operation to release, triggered by the main switch of the printing device 1 being turned ON.

[0071] That is, it is configured that the operation to release the maintenance of the closed state of the shutter 5 is executed at an appropriate timing.

[0072] Alternatively, it can also be configured that, in the case where the closed state of the shutter 5 is detected, the operation of printing is stopped, and the operation to release the closed state of the shutter 5 is performed. Even if the shutter 5 is closed during the operation of printing, it is possible to make the shutter 5 be in an open state after the operation of printing is stopped, and it is possible to start the operation of printing again.

[0073] Further, in the present embodiment, the carriage 15 reciprocally moves when performing printing, and the automatic opening mechanism 3 of the shutter is located outside the range W of the reciprocating movement of the carriage 15.

[0074] Specifically, as shown in Figure 3 , with respect to the range W of the reciprocating movement of the carriage 15 when performing printing, the automatic opening mechanism 3 of the shutter is arranged outside the range W of the reciprocating movement. That is, the automatic opening mechanism 3 is arranged so as not to affect the configuration of the printing device 1 in which the operation of printing is performed.

[0075] Restricting the movement of the carriage with a wall member

[0076] As shown in Figure 10 , in the present embodiment, a wall member 44 is arranged in front of the power receiving portion 17 of the lever 11, that is, in front of the sliding portion 19a, in a manner that it can go in and out in the up-down direction. When the carriage 15 is moved to actuate the automatic opening mechanism 3, thereby opening the shutter 5, the wall member 44 is in a retracted state, that is, it is lowered downward to retreat.

[0077] On the other hand, in the case where the automatic opening mechanism 3 is not actuated, the wall member 44 is in an extended state, that is, it is raised to a position above. For example, in the case where the carriage 15 is moved in order to detect the position of the carriage 15, the position detection is performed by making the carriage 15 abut against the wall member 44. In this case, the carriage 15 is in contact with the wall member 44, but not in contact with the power receiving portion 17 of the lever 11, so it is possible to suppress the automatic opening mechanism 3 from being actuated inadvertently.

[0078] Further, the entry and exit of the wall member 44 can be performed by a power source such as a motor provided in the printing device 1. Reference numeral 65 denotes a printing head.

[0079] Controlling the range of movement of the carriage with current values

[0080] Figure 11 is a graph showing a threshold value of a current value that controls the range of movement of the carriage 15. The horizontal axis shows the movement distance D of the carriage 15 from the origin, and the vertical axis shows the current value I flowing through the carriage 15.

[0081] When the carriage 15 starts to move from the origin and comes into contact with the power receiving portion 17 of the lever 11 of the automatic opening mechanism 3, it becomes a state of moving against the elastic force of the torsion coil spring 38, and thus the current value I flowing through the carriage 15 starts to rise. Reference numeral 46 in the graph shows the change in the current value I flowing through the carriage 15 at this time.

[0082] Reference numeral 56 shows the position of the carriage 15 at which the maintenance of the closed state of the shutter 5 is released, i.e., the position at which the engagement portion 13 of the lever 11 starts to move from the engaged portion 18 to the state in which the shutter 5 is opened. Reference numeral 50 is a first threshold value, and reference numeral 48 is a second threshold value. The first threshold value 50 is set in a region 52 from the position at which the carriage 15 comes into contact with the power receiving portion 17 of the lever 11 to the position 56 at which the shutter 5 starts to open, and the second threshold value 48 is set in a region 54 from the position at which the shutter 5 starts to open.

[0083] As shown in Figure 11 As can be understood, the region 52 is a region in which the portion of the origin ahead of the position 56 is a portion in which the carriage 15 comes into contact with the power receiving portion 17 of the lever 11, but the amount of rotation of the lever 11 is small, and the shutter 5 maintains the closed state. The first threshold value 50 set in this region 52 can be used to detect the position of the carriage 15 without causing the automatic opening mechanism 3 to act. In Figure 10 , the detection of the position of the carriage 15 is performed by bringing the carriage 15 into abutment with the wall member 44, but in Figure 11 here, the detection is performed by the first threshold value 50.

[0084] On the other hand, in the region 54, since the shutter 5 starts to open, the second threshold value 48 set in the region 54 can be used to detect the open state of the shutter 5.

[0085] Operation of the automatic opening mechanism of the shutter

[0086] Figure 1The illustrated opening and closing cover 5 is in a closed state. First, the carriage 15 moves in the -X direction, thereby coming into contact with and further pushing against the power receiving portion 17 of the sliding portion 19a of the lever 11. The lever 11 receives the power of the carriage moving in the -X direction, and rotates about the rotation fulcrum 9. By this rotation of the lever 11, the locking portion 13 of the lever 11 is disengaged from the locked portion 18 of the opening and closing cover 5. Then, the opening and closing cover 5 opens due to its own weight, and reaches Figure 2 the state shown in Figure 2 . In , the discharge tray 7 is further pulled out.

[0087] Explanation of Effects of Embodiments

[0088] (1) According to the automatic opening mechanism 3 of the present embodiment, the lever 11 rotates by the carriage 15 coming into contact with and pushing against the power receiving portion 17, and by this rotation of the lever 11, the maintenance of the closed state of the opening and closing cover 5 by the locking portion 13 is released. By this release, the opening and closing cover 5 receives a force F in the opening direction, and thus moves from the closed state to the open state by the action of this force F. Therefore, it is not necessary to add a new power by using the power of the carriage 15, and thus it is possible to realize low cost of the mechanism that automatically opens the opening and closing cover 5, and further realize space saving.

[0089] (2) In addition, according to the present embodiment, the opening and closing cover 5 is configured to have a self-weight moment on the opening side, and thus if the locked state of the locking portion 13 is released, it moves from the closed state to the open state by the self-weight. By this, it is not necessary to provide a mechanism that performs the opening operation of the opening and closing cover 5, and thus it is possible to realize low cost.

[0090] (3) In addition, according to the present embodiment, the sensor 25 that detects the opening and closing state of the opening and closing cover 5 is provided. By this, it is possible to eliminate unnecessary operation of causing the automatic opening mechanism 3 to operate in a state where the opening and closing cover 5 has already been opened, and thus it is possible to improve the convenience of use.

[0091] (4) In addition, according to the present embodiment, the power receiving portion 17 of the lever 11 is the sliding portion 19 (19a, 19b) that slides by being pushed by the carriage 15. By this, the lever 11 receives the power of the carriage 15 in the form of the sliding portion 19 sliding, and thus it is possible to effectively use the power of the carriage 15.

[0092] (5) In addition, according to the present embodiment, the sliding portion 19a becomes a state where the contact protrusion 21 of the sliding portion 19a enters the contact recess 23 provided in the carriage 15 when pushed by the carriage 15. By this, the sliding portion 19a easily moves integrally with the carriage 15, and thus it is possible to reduce the possibility of the sliding portion 19a being caught in the carriage 15.

[0093] (6) In addition, according to the printing device 1 of the present embodiment, the printing head 65 mounted on the carriage 15 and the shutter 5 that receives the force F in the opening direction are provided, and the automatic opening mechanism 3 of the shutter having the structure described above is provided. Thus, as the printing device 1, each effect of the automatic opening mechanism 3 described above can be obtained.

[0094] (7) In addition, according to the present embodiment, the carriage 15 reciprocates when performing printing, and the automatic opening mechanism 3 is located outside the range W of the reciprocation of the carriage 15. In this way, the automatic opening mechanism 3 exists independently of the printing operation of the usual printing device 1. That is, the automatic opening mechanism 3 can be provided without affecting the configuration in which the printing operation is performed in the printing device 1, and the separate production of the model having the automatic opening mechanism 3 and the model not having the automatic opening mechanism 3 can be easily performed.

[0095] (8) In addition, according to the present embodiment, by opening the shutter 5, the discharge tray 7 or the like that receives the printed matter P can be operated. Thus, the possibility of the occurrence of damage, malfunction, or the like due to the inadvertent contact with the discharge tray 7 or the like that receives the printed matter P can be reduced.

[0096] (9) In addition, according to the present embodiment, in a case where the closed state of the shutter 5 is detected during the printing operation, the printing operation is stopped, and the operation of releasing the closed state of the shutter 5 is performed. Thus, even in a case where the shutter 5 is closed during the printing operation, the shutter 5 can be brought to the open state after the printing operation is stopped, and the printing operation can be started again.
