The circuit board 96 is provided above the projecting portions 90 and 92 in the apparatus height direction.

  Further, ribs 98 and 98 extending in the apparatus height direction are formed on both side surfaces of the ink container 76 (76A, 76B) in the apparatus width direction (X-axis direction in FIG. 7), respectively. When the ink container 76 is attached to the holder 65, the rib 98 engages with the groove 84 provided on the side surface 65 b of the holder 65. As a result, the displacement of the ink container 76 (76A, 76B) in the apparatus depth direction (the Y-axis direction in FIG. 9) in the holder 65 is restricted and positioned in the apparatus depth direction.

<<< Attaching the ink container to the holder >>>
Next, with reference to FIGS. 10A and 10B, attachment of the ink container 76 to the carriage 40 will be described. In order to attach the ink container 76 to the carriage 40, the ink container 76 is inclined with respect to the holder 65 attached to the housing 63 in the apparatus depth direction rear side of the ink container 76 downward (see FIG. 10 (A) and FIG. 10 (B) (refer to the phantom line portion, hereinafter referred to as a normal insertion posture), and is inserted from the front side in the apparatus depth direction.

  When the ink container 76 is inserted in a normal insertion posture, the projecting portions 90 and 92 are inserted into the receiving portion 80 provided on the wall portion 65a on the back side of the holder 65 in the apparatus depth direction. Then, when the protrusions 90 and 92 received by the receiving part 80 are pivoted toward the apparatus depth direction front side of the ink container 76 toward the apparatus height direction lower side, the locked part 94 is moved to the first position. A second posture (FIG. 10 (A) imaginary line portion) in which the lever portion 86 in the posture (see the solid line portion in FIG. 10A) is pressed and the lever portion 86 is rotated forward to release the locked state. To change).

  When the ink container 76 is further rotated downward in the apparatus height direction, the locked portion 94 is displaced below the lever portion 86. As a result, the lever portion 86 rotates to the rear side in the apparatus depth direction and is switched from the second posture to the first posture, and the lever portion 86 locks the locked portion 94 of the ink container 76. As a result, the receiving portion 80 engages with the upper surfaces of the protruding portions 90 and 92, and together with the locked state of the locked portion 94, the displacement of the ink containing body 76 with respect to the holder 65 in the device height direction is restricted. Positioned in the direction.

  That is, in the present embodiment, since the projecting portions 90 and 92 are inserted into the receiving portion 80 configured as a concave portion, the position of the ink container 76 in the holder 65, particularly the position in the apparatus height direction, is regulated, The holding of the ink container 76 in the holder 65 can be made more reliable. Further, the attachment posture of the ink container 76 to the holder 65 is limited, and erroneous insertion into the holder 65 can be suppressed.

  When the locked portion 94 is locked by the lever portion 86, the circuit board 96 and the contact 88 are brought into contact with each other, and the circuit board 96 and the control unit 46 (see FIG. 2) are electrically connected. . Thereby, the information of the ink container 76 is transmitted and received between the circuit board 96 and the control unit 46.

  Further, the ink container 76 inserted into the holder 65 is rotated with the protrusions 90 and 92 inserted into the receiving part 80 as fulcrums with the front side in the apparatus depth direction of the ink container 76 facing downward in the apparatus height direction. When moved, the rib 98 provided on the side surface of the ink container 76 contacts the guide surface 84a (see FIG. 11) in the groove 84 of the side surface 65b of the holder 65. The rib 98 is guided by the guide surface 84 a and guided into the groove 84, and is engaged with the groove 84. As a result, the ink container 76 is normally attached to the holder 65, and an ink flow path is formed between the ink container 76 and the recording head 42, and a recording operation can be executed in the printer 10.

  That is, in this embodiment, when the ink container 76 is mounted on the holder 65, the groove 84 provided on the side surface 65b extending in the apparatus depth direction, which is the direction intersecting the wall portion 65a in the holder 65, and the ink container 76. Since the rib 98 is engaged, the ink container 76 is positioned with respect to the holder 65 in the direction intersecting the wall 65a, that is, in the apparatus depth direction, which is the direction intersecting the apparatus width direction as the predetermined movement direction, and the circuit. The contact state between the substrate 96 and the contact 88 can be more reliably maintained.

  Further, in this embodiment, since the projecting portions 90 and 92 are provided below the circuit board 96 in the apparatus height direction, the circuit board is supported in a posture in which the projecting portions 90 and 92 are supported by the support portion 65c of the wall portion 65a. The distance between 96 and the contact 88 can be increased, and the separated state between the circuit board 96 and the contact 88 can be ensured. As a result, it is possible to prevent the controller 46 (see FIG. 2) from erroneously detecting the ink container 76 in a state where the ink container 76 is erroneously inserted into the holder 65. Further, when the ink container 76 is removed from the holder 65, the circuit board 96 rotates in the direction away from the contact point 88 with the projecting portions 90 and 92 as fulcrums, so that damage to the circuit board 96 can be suppressed.

  In this embodiment, the length of the protrusions 90a and 92a located on the outer side in the apparatus width direction of the holder 65 is longer than the length of the protrusions 90b and 92b located on the inner side in the apparatus width direction of the holder 65. Since it is long, when the ink container 76 is erroneously inserted into the holder 65, the protrusions 90a and 92a on the outer side interfere with the wall 65a to suppress erroneous insertion of the ink container 76 into the holder 65. Can do. Furthermore, since the protrusions 90 b and 92 b closer to the inside in the apparatus width direction of the holder 65 are short, it is not necessary to provide relief for the protrusions 90 b and 92 b on the back side of the carriage 40.

  As a result, the belt gripping portion 64 in the driving mechanism of the carriage 40, the encoder sensor 72 as position detecting means in the moving region of the carriage 40, and the like are provided at positions corresponding to the inwardly protruding portions 90b and 92b on the back side of the carriage 40. Can be arranged. Since these structures and the projecting portions 90a and 92a closer to the outside overlap in the apparatus depth direction, which is the direction intersecting the predetermined movement direction, the increase in size of the carriage 40 can be suppressed. Miniaturization can be achieved.

<<< Incorrect insertion of ink container into holder >>>
Next, a state where the ink container 76 is erroneously inserted into the holder 65 will be described with reference to FIG. The ink container 76 is placed in the holder 65 in a wrong posture with respect to the holder 65, for example, in a posture (see FIG. 11) in which the front side in the apparatus depth direction of the ink container 76 is inclined downward in the apparatus height direction from the back side. When the ink container 76 is inserted or inserted straight from the upper side in the apparatus height direction without being inclined with respect to the holder 65, the longer protrusions 90a, 92a of the ink container 76 (76A, 76B) are formed. The holder 65 comes into contact with the support portion 65c of the wall portion 65a on the back side in the apparatus depth direction.

  The longer protrusions 90a, 92a of the ink container 76 (76A, 76B) are supported by the support portion 65c of the wall portion 65a. Further, in this state, a part of the locked portion 94 (see the imaginary line portion in FIG. 11) of the ink container 76 is positioned above the lever portion 86 and supported by the lever portion 86. Thereby, the state where the circuit board 96 and the contact 88 of the ink container 76 are separated is maintained. As a result, even if the ink container 76 is erroneously inserted into the holder 65, the circuit board 96 and the control unit 46 (see FIG. 2) are not electrically connected. Is not detected.

  Therefore, in this embodiment, if the ink container 76 is inserted into the holder 65 in an incorrect posture, the protrusions 90 a and 92 a are supported by the support part 65 c, so that the ink container 76 is erroneously inserted into the holder 65. Insertion can be prevented.

  In other words, in the present embodiment, the circuit board 96 and the contact 88 are separated from each other in a posture in which the protruding portions 90 and 92 of the ink container 76 are supported by the support portion 65c positioned above the receiving portion 80 of the holder 65. Therefore, the control unit 46 (see FIG. 2) does not detect the ink container 76 when the ink container 76 is erroneously inserted into the holder 65. As a result, since the control unit 46 does not erroneously detect the ink container 76, the execution of the recording operation of the printer 10 when the ink container 76 is erroneously inserted can be reduced or prevented.

  When the ink container 76 is in this state, if the force is applied from above in the apparatus height direction to push the ink container 76 into the holder 65, the force acts on the lever portion 86 in the vertical direction. As a result, since the action of the force in the direction of rotating the lever portion 86 is reduced, the rotation of the lever portion 86 is suppressed, and the change of the lever portion 86 from the first posture to the second posture is suppressed. Thus, the switching of the lever portion 86 from the first posture to the second posture becomes impossible.

  That is, in this embodiment, the lever portion 86 cannot be switched from the second posture to the first posture in the posture in which the protruding portions 90 and 92 are supported by the support portion 65c of the wall portion 65a. The locked portion 94 of the ink container 76 is not locked by the lever portion 86. Accordingly, since the ink container 76 is prevented from being erroneously inserted into the holder 65, the contact between the circuit board 96 and the contact 88 can be suppressed, and erroneous detection of the ink container 76 is suppressed. As a result, the execution of the recording operation of the printer 10 when the ink container 76 is erroneously inserted can be reduced or prevented.

<<< Modification of the first embodiment >>>
In this embodiment, the lengths of the longer protrusions 90a, 92a in the ink container 76A, 76B in the apparatus depth direction are the same, but instead of this structure, the length of the protrusion 90a of the ink container 76A is the same. The length may be longer than the length of the protrusion 92a of the ink container 76B, or the length of the protrusion 92a of the ink container 76B may be longer than the length of the protrusion 90a of the ink container 76A. Good.

  With this configuration, the ink container 76B cannot be attached to the attachment position of the ink container 76A in the holder 65, and the ink container 76A cannot be attached to the attachment position of the ink container 76B. Incorrect insertion due to an incorrect attachment position of the bodies 76A and 76B can be reduced.

■■■ Second Example ■■■■■■■
<<< About the composition of the holder >>>
Next, a second embodiment will be described with reference to FIGS. As shown in FIG. 12, the casing 100 of the carriage 99 is formed in a box shape and opens upward. Further, in the casing 100, grooves 102 and 102 extending in the apparatus height direction are formed on the back side in the apparatus depth direction. A holder 104 is attached to the housing 100.

  The holder 104 is formed in a box shape and opens upward. A wall 104a is formed on the back side of the holder 104 in the apparatus depth direction. The wall portion 104a is provided with receiving portions 106 and 106 at both ends in the apparatus width direction. The receiving portion 106 extends in the apparatus height direction, and corresponds to the length of a protruding portion 110 of an ink container 108 to be described later. Moreover, the receiving part 106 has penetrated the wall part 104a. In the receiving unit 106, the groove 102 forms a bottom surface and functions as a recess when the holder 104 is mounted on the housing 100. In addition, a plurality of ink flow passage openings 82 for supplying ink to the recording head 42 are formed on the bottom surface of the holder 104.

  In the holder 104, side walls 104b extending in the apparatus depth direction are formed at both ends of the wall 104a in the apparatus width direction (X-axis direction in FIG. 12). A groove 105 (see FIG. 15) extending in the apparatus height direction is formed on the side surface 104b.

<<< Construction of Ink Container >>>
Referring to FIG. 13, the ink container 108 is configured as a composite cartridge that stores each color of black, cyan, magenta, and yellow. A protrusion 110 is provided on the back side of the ink container 108 in the apparatus depth direction (the + Y axis direction side in FIG. 13). The protrusions 110 are formed at both ends in the apparatus width direction (X-axis direction in FIG. 13) on the back surface of the ink container 108 so as to protrude from the back surface of the ink container 108 toward the device back side.

  Moreover, the protrusion part 110 is extended in the apparatus height direction (Z-axis direction in FIG. 13) downward. Specifically, when the protruding portion 110 is received by the receiving portion 106, the position restricting portion 110a for restricting the position of the ink container 108 in the device height direction, and the position restricting portion 110a on the lower side in the device height direction. And an extending portion 110b that extends. Further, in the ink container 108, ribs 112 extend along the apparatus height direction on both side surfaces in the apparatus width direction.

  As shown in FIG. 14, the protrusion 110 of the ink container 108 is received by the receiving part 106 in a state where the ink container 108 is attached to the holder 104. When the ink container 108 is attached to the holder 104, the ink container 108 is inclined with respect to the holder 104 in the apparatus depth direction back side of the ink container 108 downward (hereinafter referred to as a normal insertion position). ) From the front side in the depth direction of the device.

  Then, the protruding portion 110 is inserted into the receiving portion 106, and the ink container 108 is rotated toward the lower side in the apparatus height direction with the protruding portion 110 serving as a fulcrum. 108 is installed normally. When the ink container 108 is inserted into the holder 104 in a normal insertion posture, the rib 112 is guided along the groove 105 and engaged with the groove 105.

  Then, the circuit board 96 provided on the front side in the apparatus depth direction of the ink container 108 and the contact 88 provided on the carriage 99 are in contact with each other, and the circuit board 96 and the control unit 46 (see FIG. 2) are electrically connected. Connected. Thereby, the information of the ink container 108 is transmitted and received between the circuit board 96 and the control unit 46.

<<< Incorrect insertion of ink container into holder >>>
With reference to FIG. 15, a state where the ink container 108 is erroneously inserted into the holder 104 will be described. The ink container 108 is placed in the holder 104 in a wrong posture with respect to the holder 104, for example, in a posture (see FIG. 15) in which the front side in the apparatus depth direction of the ink container 108 is inclined downward in the apparatus height direction from the back side. When the ink container 108 is inserted or inserted straight down from the upper side in the apparatus height direction without being inclined with respect to the holder 104, the lower end of the extended portion 110 b of the protrusion 110 of the ink container 108 is connected to the holder 104. It contacts the supporting portion 104c (see FIG. 15) of the wall portion 104a on the back side in the apparatus depth direction.

  And the protrusion part 110 of the ink container 108 is supported by the support part 104c of the wall part 104a. At this time, by increasing the length of the extending portion 110b in the apparatus height direction, the position of the circuit board 96 in the apparatus height direction with respect to the holder 104 can be increased. Thereby, the distance in the apparatus height direction of the circuit board 96 and the contact 88 can be lengthened, and a separated state can be maintained more reliably.

  Further, in this state, the rib 112 of the ink container 108 is supported by the upper end portion 104 d of the side surface 104 b of the holder 104, and the rib 112 is not guided into the groove 105. In this state, the circuit board 96 of the ink container 108 and the contact point 88 of the carriage 99 are kept apart.

  That is, in this embodiment, since the projecting portion 110 extends in the device height direction, the device height of the circuit board 96 relative to the holder 104 in a posture in which the projecting portion 110 is supported by the support portion 104c of the wall portion 104a. The position in the direction can be increased. As a result, the distance between the circuit board 96 and the contact 88 in the apparatus height direction can be increased. Accordingly, the circuit board 96 and the contact 88 can be reliably separated from each other, so that erroneous detection of the ink container 108 in the erroneous insertion posture of the ink container 108 with respect to the holder 104 can be reduced.

  In the present embodiment, the upper end portion 104d of the side surface 104b of the holder 104 supports the rib 112 in a posture in which the protruding portion 110 is supported by the support portion 104c of the wall portion 104a. Insertion can be suppressed. As a result, the separated state between the circuit board 96 and the contact 88 can be maintained, erroneous detection of the ink container 108 can be reduced, and malfunction of the printer 10 can be suppressed.

  In other words, in this embodiment, if the ink container 108 is inserted into the holder 104 in an incorrect posture, the protruding part 110 is supported by the support part 104c, and therefore the ink container 108 is erroneously inserted into the holder 104. Can be prevented.

<<< Modified Example of First and Second Embodiments >>>
In the first and second embodiments, the contact 88 that contacts the circuit board 96 provided in the ink containers 76 and 108 is provided in the holders 65 and 104. However, instead of this configuration, the contact 88 is provided. May be provided in the casings 63 and 100 of the carriages 40 and 99.

<<< Mechanism for adjusting the distance between the carriage and the guide frame >>>
The means for adjusting the distance between the carriages 40 and 99 and the guide frame 66 will be described with reference to FIGS. 4, 10A and 10B again and with reference to FIG. In the following description, the carriage 40 will be described as an example.

  In FIG. 4, interval adjusting means 114, 114 are provided on both sides in the apparatus width direction (X-axis direction in FIG. 4) of the belt gripping portion 64 provided on the back side of the carriage 40. As shown in FIG. 16, the interval adjusting unit 114 includes a holding member 116, an urging member 118, and a pressing member 120.

  The holding member 116 is disposed on the back side in the apparatus depth direction of the opening 122 provided on the back side of the casing 63 of the carriage 40. A biasing member 118 is attached to the holding member 116 in the opening 122. A pressing member 120 is disposed on the front side of the opening 122 in the apparatus depth direction.

  An urging member 118 is attached to the back side of the pressing member 120 in the apparatus depth direction. That is, the pressing member 120 is configured to be able to advance and retract in the apparatus depth direction by the urging force of the urging member 118 at the opening 122.

  The pressing member 120 urges a portion 66a (see FIGS. 10A and 10B) standing on the guide frame 66 in the apparatus height direction on the front side in the apparatus depth direction.

  In addition, an engaging portion 124 is provided at a position facing the pressing member 120 in the apparatus depth direction in the housing 63. The standing portion 66a of the guide frame 66 is sandwiched between the pressing member 120 and the engaging portion 124 that bias the standing portion 66a by receiving the biasing force of the biasing member 118 in the apparatus depth direction.

  When the carriage 40 moves in the apparatus width direction, the pressing member 120 advances and retreats in the apparatus depth direction even if there is a difference in thickness or undulation in the standing portion 66a of the guide frame 66 extending in the apparatus width direction. In response to the urging force, the standing portion 66 a of the guide frame 66 is pressed against the engaging portion 124. As a result, the carriage 40 moves in the apparatus width direction with reference to the engagement position between the engaging portion 124 and the standing portion 66a in the apparatus depth direction. Therefore, the interval adjusting unit 114 can restrict the displacement of the carriage 40 in the apparatus depth direction, and can improve the movement accuracy in the apparatus depth direction when the carriage 40 moves in the apparatus width direction.

<<< Timing belt dropout prevention means >>>

As a result, a rotational moment R1 is generated in the carriage 40 so as to rotate the carriage 40 in the clockwise direction in FIG. 17 with the contact portion 128 as a fulcrum.

  As a result, the belt gripping portion 64 tries to rotate in the clockwise direction in FIG. 17 with respect to the timing belt 62, so that the timing belt 62 is detached from the belt gripping portion 64 in the direction toward the back of the apparatus (the direction of the arrow in FIG. 17). There is a risk of doing.

  In this embodiment, since the belt dropout prevention portion 126 is disposed near the driven pulley 60 away from the belt gripping portion 64 in the apparatus width direction, the carriage 40 is rotated clockwise in FIG. 17 with the contact portion 128 as a fulcrum. When trying to rotate, the timing belt 62 can be restrained at a position away from the belt gripping portion 64 serving as a fulcrum of rotation. As a result, the belt drop prevention unit 126 suppresses the belt gripping portion 64 relative to the timing belt 62 and, consequently, the clockwise rotation of the carriage 40 in FIG. 17, thereby reducing the fall of the timing belt 62 from the belt gripping portion 64.
