It becomes possible to keep on.

(4) The cartridge according to the above aspect may further include a detection unit on the first surface that can optically detect the printing material in the cartridge, and the printing material supply port may be included in the first surface. The detection unit may be provided in a portion closer to the fourth surface than the third surface, and the detection unit may be provided in a portion of the first surface closer to the third surface than the fourth surface. . In the case of such a cartridge, since the printing material supply port and the detection unit can be arranged separately on the first surface, the printing material is detected when the printing material leaks from the printing material supply port. It can suppress adhering to a part. As a result, it is possible to accurately detect the printing material using the detection unit.

(5) In the cartridge according to the above aspect, a plurality of the printing material supply ports may be provided on the first surface along the width direction, and the second cartridge side regulating portion may be disposed along the width direction. A plurality of fourth surfaces may be provided. Even in such a cartridge, the maximum width of the printing material supply port is formed to be larger than the interval between the two contact portions farthest apart in the width direction in the terminal group, and the second cartridge side regulating portion Since the maximum width is larger than the maximum width of the first cartridge-side restricting portion, the connection state between the printing material supply port and the printing material introduction port on the holder side is excellent when mounted on the printing apparatus. In addition, the contact state between the terminal group and the contacts provided on the holder side can be maintained well.

In another embodiment, two or more cartridges 20 may be mounted on the holder 60 corresponding to one color ink. Detailed configurations of the cartridge 20 and the holder 60 will be described later.

  The printer 50 of the printing material supply system 10 is a small inkjet printer for individuals. In addition to the holder 60, the printer 50 includes a control unit 510 and a carriage 520 having the holder 60. The carriage 520 includes a head 540. The printer 50 circulates ink from the cartridge 20 mounted in the holder 60 to the head 540 via a printing material supply pipe described later, and discharges (supplies) ink from the head 540 to a printing medium 90 such as paper or a label. To do. As a result, data such as characters, graphics, and images is printed on the print medium 90 using the head 540.

  The control unit 510 of the printer 50 controls each unit of the printer 50. The carriage 520 of the printer 50 is configured to be able to move the head 540 relative to the print medium 90. The head 540 of the printer 50 includes an ink ejection mechanism that ejects ink from the cartridge 20 mounted on the holder 60 onto the print medium 90. The controller 510 and the carriage 520 are electrically connected via a flexible cable 317, and the ink ejection mechanism of the head 540 operates based on a control signal from the controller 510.

  In the present embodiment, the carriage 520 includes a holder 60 together with the head 540. As described above, the type of the printer 50 in which the cartridge 20 is mounted in the holder 60 on the carriage 520 that moves the head 540 is also referred to as an “on-carriage type”. In another embodiment, the immovable holder 60 is configured in a different part from the carriage 520, and the ink from the cartridge 20 mounted on the holder 60 is supplied to the head 540 of the carriage 520 via the flexible tube. good. Such a printer type is also called an “off-carriage type”.

  In the present embodiment, the printer 50 includes a main scan feed mechanism and a sub scan feed mechanism for realizing printing on the print medium 90 by relatively moving the carriage 520 and the print medium 90. The main scanning feed mechanism of the printer 50 includes a carriage motor 522 and a driving belt 524, and transmits the power of the carriage motor 522 to the carriage 520 via the driving belt 524, thereby reciprocating the carriage 520 in the main scanning direction. The sub-scan feed mechanism of the printer 50 includes a transport motor 532 and a platen 534, and transmits the power of the transport motor 532 to the platen 534, thereby transporting the print medium 90 in the sub-scan direction orthogonal to the main scan direction. The carriage motor 522 of the main scan feed mechanism and the transport motor 532 of the sub scan feed mechanism operate based on a control signal from the control unit 510.

  In the present embodiment, in the use state (also referred to as “use posture”) of the printing material supply system 10, the axis along the sub-scanning direction (front-rear direction) for transporting the print medium 90 is the X axis, and the carriage 520 is reciprocated. An axis along the main scanning direction (left-right direction) to be moved is a Y-axis, and an axis along the gravity direction (up-down direction) is a Z-axis. The usage state of the printing material supply system 10 is the state of the printing material supply system 10 installed on a horizontal surface. In this embodiment, the horizontal surface is a surface parallel to the X axis and the Y axis (XY). Plane).

In the present embodiment, the + X axis direction side (front side) is the front surface of the printing material supply system 10. In the present embodiment, the direction from the right side surface to the left side surface of the printing material supply system 10 is defined as + Y axis direction (left direction), and the opposite direction is defined as −Y axis direction (right direction). In the present embodiment, the arrangement direction of the plurality of cartridges 20 attached to the holder 60 is a direction along the Y axis (left and right direction, also simply referred to as “Y axis direction”). The direction along the X axis (front-rear direction) is also referred to as the “X-axis direction”, and the direction along the Z axis (up-down direction) is also referred to as the “Z-axis direction”.

  2 and 3 are perspective views showing the holder 60 to which the cartridge 20 is mounted. FIG. 4 is a top view showing the holder 60 to which the cartridge 20 is mounted. 2 to 4 show a state in which one cartridge 20 is correctly mounted in the designed mounting position in the holder 60. Note that “the state of being correctly mounted at the designed mounting position” means that each terminal of the cartridge-side terminal group, which will be described later, contacts each corresponding terminal of the terminal group of the contact mechanism of the printer 50. The state where is located.

  As shown in FIGS. 2 and 3, the holder 60 of the printer 50 has five walls 601, 603, 604, 605, and 606. A concave portion formed by these five wall portions becomes a cartridge housing chamber 602 (also referred to as “cartridge mounting portion 602”). The cartridge housing chamber 602 is divided by a partition wall 607 into a plurality of slots (mounting spaces) that can receive the cartridges 20. Such a partition wall 607 functions as a guide when the cartridge 20 is inserted into the slot, but may be omitted. Each slot is provided with a printing material supply pipe 640 serving as an ink introduction port, a contact mechanism 70, a lever 80, a second device-side restricting portion 620, and a projection 636 serving as a third device-side restricting portion. ing. One side surface (+ Z-axis side surface; upper surface) of each slot is opened, and the cartridge 20 is attached to and detached from the holder 60 through the opened one side surface (upper surface).

  The cartridge 20 is locked by the lever 80 and the second device-side regulating unit 620, and a printing material supply port, which will be described later, is connected to the printing material supply pipe 640, so that the cartridge 20 is mounted on the holder 60. This state is also referred to as “a state where the cartridge 20 is attached to the holder 60” or “an attached state”. The printing material supply pipe 640 is connected to the printing material supply port of the cartridge 20, and thereby distributes the ink as the printing material stored in the cartridge 20 to the head 540. The printing material supply pipe 640 has a distal end portion (also referred to as “connection end portion”) 642 positioned on the + Z axis side and a proximal end portion 645 positioned on the −Z axis side. The base end portion 645 is provided on the bottom wall portion 601. The leading end 642 is connected to the printing material supply port of the cartridge 20. The central axis C of the printing material supply pipe 640 is parallel to the Z axis. The direction from the base end 645 toward the tip end 642 along the central axis C is the + Z axis direction.

  As shown in FIG. 2, an elastic member 648 is provided around the printing material supply pipe 640. The elastic member 648 seals the periphery of the printing material supply port of the cartridge 20 in the mounted state. Accordingly, the elastic member 648 prevents ink from leaking out from the printing material supply port. In the mounted state, the elastic member 648 applies a biasing force including a component in the + Z-axis direction to the cartridge 20.

  Further, in the mounted state, various information is transmitted between the cartridge 20 and the printer 50 by electrically connecting a terminal group provided on a circuit board (to be described later) of the cartridge 20 and the contact mechanism 70.

  FIG. 5 is a schematic cross-sectional view taken along F4-F4 in FIG. In addition, illustration of the protrusion part 636 is abbreviate | omitted. The printing material supply pipe 640 of the printer 50 is connected to the printing material supply port 280 of the cartridge 20 to supply the ink in the printing material container 200 to the head 540 via the printing material flow path 282.

  In the present embodiment, a porous body filter 644 that filters ink from the cartridge 20 is provided at the distal end 642 of the printing material supply pipe 640. As the porous filter 644, for example, a stainless mesh, a stainless nonwoven fabric, or the like can be used. In other embodiments, the porous filter may be omitted from the tip 642 of the printing material supply pipe 640.

  The contact mechanism 70 of the printer 50 is provided on the + X axis direction side of the printing material supply pipe 640 and is configured to be electrically connectable to a terminal group provided on the circuit board 40 of the cartridge 20. The mounted cartridge 20 receives a biasing force Pt including a component in the + Z-axis direction from the terminal of the contact mechanism 70 to the circuit board 40. Further, the mounted cartridge 20 receives a biasing force Ps in the + Z-axis direction from the elastic member 648 to the printing material supply port 280. In the present embodiment, the urging force Ps received by the printing material supply port 280 is larger than the urging force Pt received by the circuit board 40. “Energizing force” can also be called “reaction force”. The biasing force Pt received by the circuit board 40 is substantially the biasing force received by the cartridge side terminal group 400 from the terminals of the contact mechanism 70.

  The lever 80 used for attaching and detaching the cartridge 20 has an operation unit 830 at the end on the + Z-axis direction side and a first device-side regulating unit 810 at the end on the −Z-axis direction side. In the mounted state, the first device side restricting portion 810 (the first device side engaging surface described in detail later) is the first cartridge side restricting portion at the first engaging position 810L which is a predetermined engaging position. 210 can be locked. The first locking position 810L is located on the + Z axis direction side and the + X axis direction side from the position where the terminal group provided on the circuit board 40 and the contact mechanism 70 are in contact with each other. The first device-side restricting portion 810 restricts the movement of the cartridge 20 in the + Z-axis direction by engaging with the first cartridge-side restricting portion 210.

  The lever 80 rotates about a position between the operation unit 830 and the first device side regulating unit 810 as an axis 800c. The rotation shaft 800c of the lever 80 is located on the + Z axis direction side and the + X axis direction side from the first locking position 810L.

  The operation unit 830 of the lever 80 is used when the user removes the cartridge 20 from the holder 60. When removing the cartridge 20, the user pushes the operation unit 830 in the −X axis direction. At this time, a force Pr (also referred to as “operation force Pr”) from the + X axis direction side to the −X axis direction side is applied to the operation unit 830. Then, the lever 80 rotates about the shaft 800c, and the first device side regulating portion 810 moves from the first locking position 810L in the + X axis direction. As a result, the locking of the first cartridge side regulating portion 210 by the first device side regulating portion 810 is released, and the cartridge 20 can be removed from the holder 60.

  A second device side regulating portion 620 is provided on the side wall portion 604. The second apparatus-side restricting portion 620 is configured to be able to lock the second cartridge-side restricting portion 220 at the second locking position 620L. In the present embodiment, the second device-side restricting portion 620 is a through hole formed in the side wall portion 604 of the holder 60. The second locking position 620L is located on the + Z-axis direction side and the −X-axis direction side of the printing material supply pipe 640. The second device side regulating unit 620 regulates the movement of the cartridge 20 in the + Z-axis direction by locking the second cartridge side regulating unit 220. Thus, in the mounted state, the cartridge 20 is restricted from moving in the + Z-axis direction on both sides of the end in the + X-axis direction and the end in the −X-axis direction.

  The vicinity of the second locking position 620L where the second cartridge side regulating portion 220 and the second device side regulating portion 620 come into contact becomes a rotation fulcrum when the cartridge 20 is attached to and detached from the holder 60. That is, the cartridge 20 is attached and detached while rotating the cartridge 20 along a plane parallel to the Z axis and the X axis around the second locking position 620L.

  As shown in FIG. 5, in the mounted state, the first locking position 810L is positioned on the −Z axis direction side by a distance Dz from the second locking position 620L. Therefore, it is possible to reduce the possibility that the first cartridge side regulating portion 210 and the first device side regulating portion 810 are unlocked by the urging forces Ps and Pt from the holder 60 to the cartridge 20. Thereby, the cartridge 20 can be stably held at the designed mounting position.

  FIG. 6 is a perspective view showing the configuration of the cartridge 20. FIG. 7 is a bottom view of the cartridge 20. 8 is a schematic cross-sectional view taken along the line F8-F8 in FIG. In the present embodiment, the X axis, the Y axis, and the Z axis for the cartridge 20 in the mounted state are axes on the cartridge. In the present embodiment, the + X axis direction side is the front surface of the cartridge 20 in the mounted state. The plane Yc shown in FIG. 7 is a plane (ZX plane) that passes through the center of the width that is the length of the cartridge 20 in the Y-axis direction and is parallel to the Z-axis and the X-axis. 7 is a plane (ZX plane) that passes through the central axis C and is parallel to the Z axis and the X axis.

  As shown in FIG. 6, the cartridge 20 includes a printing material storage unit 200 that stores ink, an outer shell 22, a printing material supply port 280, a circuit board 40, a prism 270, and a first cartridge side regulation unit. 210. The mounting direction SD when mounting the cartridge 20 on the holder 60 is the −Z-axis direction (in the present embodiment, the vertically downward direction). Here, when the cartridge 20 is actually inserted into the holder 60, the state of the cartridge 20 is not always constant. In the middle of trying to attach the cartridge 20 to the holder 60, the state of the cartridge 20 may be tilted with respect to the Z axis. However, immediately before mounting and in the mounted state, the printing material supply port 280 receives the printing material supply pipe 640 having the central axis C parallel to the Z axis, and the state of the cartridge 20 is regulated by the printing material supply pipe 640. Will be. Therefore, it can be said that the cartridge 20 is attached to the holder 60 in the −Z-axis direction.

  The outer shell (also referred to as “cartridge main body”) 22 defines an internal space including the printing material accommodation unit 200 of the cartridge 20. The outer shell 22 constitutes at least a part of the outer wall surface of the cartridge 20. The outer shell 22 is made of a synthetic resin such as polypropylene (PP). The cartridge 20 has a substantially prismatic shape with side surfaces having a congruent shape. Further, it can be said that the cartridge 20 has a substantially rectangular parallelepiped shape. A part of the outer shell 22 may be formed of a resin film.

  The cartridge 20 has a length (length in the X-axis direction), width (length in the Y-axis direction), and height (length in the Z-axis direction) in the order of length, height, and width. The magnitude relationship between the length, width, and height of the cartridge 20 can be arbitrarily changed. For example, the cartridge 20 may be increased in the order of height, length, and width, or may have the same height, length, and width. good.

  The outer shell 22 of the cartridge 20 has a first wall 201, a second wall 202, a third wall 203, a fourth wall 204, a fifth wall 205, a sixth wall 206, and a connection wall 209. . The connection wall 209 has a seventh wall 207 and an eighth wall 208 (FIG. 8). The first to eighth walls 201 to 208 define an internal space including the printing material accommodation unit 200 of the cartridge 20. In the following description, reference numerals 201 to 208 are also used to mean the outer surfaces (first to eighth surfaces 201 to 208) of the wall constituting the outer shell 22 of the cartridge. Outer surfaces (first to eighth surfaces) 201 to 208 of the first to eighth walls are generally flat. A substantially flat surface includes a case where the entire surface is completely flat and a case where a part of the surface is uneven. That is, it includes a case where the surface or wall constituting the outer shell of the cartridge 20 can be grasped even if there is some unevenness on a part of the surface. The outer shapes of the first to eighth surfaces 201 to 208 in plan view are all substantially rectangular.

  Here, the first surface (first wall) 201 is also called a bottom surface (bottom wall), the second surface (second wall) 202 is also called an upper surface (upper wall), and the third surface (third wall) 203 is a front surface. (Front wall), the fourth surface 204 (fourth wall) is also referred to as the back surface (rear wall), the fifth surface 205 (fifth wall) is also referred to as the left side surface (left wall), and the sixth surface (sixth wall). Wall 206 is also referred to as the right side (right wall).

  The first surface 201 and the second surface 202 face each other in the Z-axis direction. The first surface 201 is located on the −Z axis direction side. The second surface 202 is located on the + Z axis direction side. The third surface 203 and the fourth surface 204 oppose each other in the X-axis direction. The third surface 203 is located on the + X axis direction side. The fourth surface 204 is located on the −X axis direction side. The fifth surface 205 and the sixth surface 206 face each other in the Y-axis direction. The fifth surface 205 is located on the + Y axis direction side. The sixth surface 206 is located on the −Y axis direction side.

  In the present embodiment, the first surface 201 located on the −Z-axis direction side is a surface that becomes the bottom surface in the mounted state. The first surface 201 is a horizontal surface in the mounted state. That is, the first surface 201 is a surface (XY plane) parallel to the X axis and the Y axis and perpendicular to the Z axis.

The second cartridge side regulating portion 220 is inserted into the second device side regulating portion 620 (FIG. 3) which is a through hole of the holder 60. When the user attaches / detaches the cartridge 20 to / from the holder 60, the cartridge 20 is rotated about the vicinity of the second cartridge side regulating portion 220 inserted into the second device side regulating portion 620 (FIG. 3). Let That is, the second device-side regulating unit 620 functions as a guide when the cartridge 20 is attached to and detached from the holder 60. Thereby, the cartridge 20 can be easily attached to and detached from the holder 60. Further, in the mounted state of the cartridge 20, the second cartridge side regulating unit 220 is locked to the second device side regulating unit 620 and regulates the movement of the cartridge 20 in the mounted state. The second cartridge side regulating portion 220 is provided on the + Z axis direction side and the −X axis direction side from the printing material supply port 280 and the circuit board 40.

  Further, the protruding portion 260 is provided on the third surface 203 at a position on the + Z-axis direction side of the first cartridge side regulating portion 210. In the present embodiment, the protruding portion 260 is provided in a portion of the third surface 203 that is located on the most + Z-axis direction side (uppermost side) including the second side 291.

  The third cartridge side regulating portion 250 is a pair of projecting members (regulating walls) projecting in the + X axis direction from both sides of the seventh surface 207 in the Y axis direction. The pair of projecting members 250 receives the projecting portion 636 (FIG. 2) therebetween, thereby restricting movement in the Y-axis direction in the mounted state in cooperation with the projecting portion 636.

  FIG. 9 is a rear view of the cartridge 20. Details of the second cartridge side regulating portion 220 will be described with reference to FIG. The second cartridge side restricting portion 220 includes a first restricting / engaging surface 222 as a first restricting / engaging portion, an inclined surface 224, a first restricting side surface 226, and a second restricting side surface 228. Have.

  The first restriction locking surface 222 is a surface facing the + Z-axis direction and is a horizontal surface in the mounted state. When the cartridge 20 is rotated and removed from the holder 60, the first restriction locking surface 222 comes into contact with the second device side restriction portion 620 (FIG. 3) to form a rotation fulcrum.

  Further, the first restriction locking surface 222 is locked to the second device side restriction portion 620 in the mounted state, thereby restricting the movement of the cartridge 20 in the + Z-axis direction in the mounted state. The first restricting / locking surface 222 is provided at a position crossing the plane Yc passing through the center of the width (length in the Y-axis direction) of the cartridge 20 and perpendicular to the plane Yc. As shown in FIG. 5, in the mounted state of the cartridge 20, the cartridge 20 receives urging forces Ps and Pt including components in the + Z axis direction from the holder 60. Then, the first restriction locking surface 222 is pressed against the second device side restriction portion 620 by such urging forces Ps and Pt. At this time, the second device-side restricting portion 620 contacts the first restricting / engaging surface 222 in parallel with the Y-axis direction. Therefore, the possibility that the cartridge 20 tilts around the X axis in the mounted state can be reduced.

  The inclined surface 224 is connected to the first restriction locking surface 222 and is inclined toward a direction including components in the + Z-axis direction and the −X-axis direction. Accordingly, when the cartridge 20 is mounted on the holder 60, the first restriction locking surface 222 can be smoothly guided to the second device side restriction portion 620.

The first and second regulating side surfaces 226 and 228 are planes parallel to the X-axis direction and the Z-axis direction, respectively. The first and second restricting side surfaces 226 and 228 restrict the movement of the cartridge 20 in the Y-axis direction by interfering with the second device side restricting portion 620 in the mounted state of the cartridge 20.

  FIG. 10 is a front view of the cartridge 20. The first cartridge side restricting portion 210 will be further described with reference to FIG. The first cartridge side regulating portion 210 is provided at a position crossing the plane Yc. Further, the first cartridge side locking surface 211 is provided at a position crossing the plane Yc and perpendicular to the plane Yc.

  The first cartridge-side locking surface 211 has the first outer portion 435P and the second portion in the Y-axis direction (width direction) (when the cartridge 20 is viewed from the third surface 203 side in the −X-axis direction). It is located inside the range 40Y without being located outside the range 40Y between the outer portions 439P. In the present embodiment, the first cartridge side regulating portion 210 including the first cartridge side locking surface 211 is positioned inside the range 40Y without being positioned outside the range 40Y. That is, the first cartridge-side restricting portion 210 is located inside a region sandwiched between the first imaginary line 435PL including the first outer portion 435P and the second imaginary line 439PL including the second outer portion 439P. The first virtual line 435PL and the second virtual line 439PL are straight lines extending along the Z-axis direction, respectively.

  As shown in FIG. 7, in the present embodiment, when the Y-axis direction orthogonal to the fifth surface 205 and the sixth surface 206 is the width direction, the maximum width of each part shown below is expressed by the following inequality (1). It is set to satisfy. The maximum width refers to the width of the part where the width of each part is maximum.

W1... Maximum width of second cartridge side regulating portion 220 W2... Maximum width of printing material supply port 280 W3... Maximum width of prism 270 W4. Maximum width of first cartridge side restricting portion 210

  W2> W1> W4> W3> W5 (1)

  According to the inequality (1), the maximum width W2 of the printing material supply port 280 is larger than the maximum width W4 of the circuit board 40 located on the + X-axis direction side of the printing material supply port 280. Further, the maximum width W1 of the second cartridge side regulating portion 220 located on the −X axis direction side from the printing material supply port 280 is the first cartridge side regulating portion located on the + X axis direction side from the circuit board 40. It is larger than the maximum width W5 of 210. Further, the maximum width W3 of the prism 270 located on the + X-axis direction side with respect to the printing material supply port 280 and on the −X-axis direction side with respect to the circuit board 40 is larger than the maximum width W5 of the first cartridge side regulating portion 210. It is large and smaller than the maximum width W4 of the circuit board 40.

  When the cartridge 20 of this embodiment is mounted on the holder 60 of the printer 50, the printing material supply port 280 and the circuit board 40 are in contact with the elastic member 648 on the holder 60 side and the contact mechanism 70, respectively. In the present embodiment, since the maximum width W2 of the printing material supply port 280 is set wider than the maximum width W4 of the circuit board 40, the cartridge 20 is inclined in the width direction (Y-axis direction) in the holder 60. In this case, that is, when a rotational deviation about the X axis occurs, the printing material supply port 280 has a larger rotational deviation than the circuit board 40. However, in the present embodiment, when the first surface 201 is viewed from the −Z-axis direction to the + Z-axis direction, the maximum width W1 of the second cartridge-side regulating portion 220 provided near the printing material supply port 280 is Since it is set wider than the maximum width W5 of the first cartridge side restricting portion 210 provided near the circuit board 40, the printing material supply port 280 is provided even if the above rotational deviation occurs. An increase in the amount of rotational deviation can be suppressed. As a result, the connection state between the printing material supply port 280 and the printing material supply pipe 640 and the contact state between the cartridge-side terminal group 400 and the contact mechanism 70 can be maintained well.

  Further, in the present embodiment, when the first surface 201 is viewed from the −Z axis direction to the + Z axis direction, the maximum width W1 of the second cartridge side regulating portion 220 provided near the printing material supply port 280 is Since it is set wider than the maximum width W5 of the first cartridge side restricting portion 210 provided near the circuit board 40, the structure of the second cartridge side restricting portion 220 can be applied to the force received from the Z-axis direction. It is easy to make a stronger structure. Therefore, as in this embodiment, the biasing force Ps received by the printing material supply port 280 from the elastic member 648 on the holder 60 side is greater than the biasing force Pt received by the circuit board 40 from the terminal of the contact mechanism 70 on the holder 60 side. The contact state between the printing material supply port 280 and the printing material supply pipe 640 and the contact state between the cartridge-side terminal group 400 on the circuit board 40 and the contact mechanism 70 are kept good. It is possible.

  In the present embodiment, the printing material supply port 280 is provided in a portion closer to the fourth surface 204 than the third surface 203 in the first surface 201 of the cartridge 20, and the prism 270 is formed on the first surface 201. Among these, it is provided in a portion closer to the third surface than the fourth surface. In other words, since the printing material supply port 280 and the prism 270 are arranged at positions separated from each other on the first surface 201, when ink leaks from the printing material supply port 280, the ink adheres to the prism 270. Can be suppressed. As a result, it is possible to improve the detection accuracy of the remaining amount of ink using the prism 270.

It may be set wider than the interval W41. The maximum width W2 of the printing material supply port 280 is the two contact portions cp1 farthest in the Y-axis direction among the contact portions where the cartridge side terminal group 400 of the circuit board 40 contacts the contact mechanism 70 on the holder 60 side. , Cp2 may be set wider than the interval W42. Even if the maximum width W2 of the printing material supply port 280 is set as described above, the connection state between the printing material supply port 280 and the printing material supply pipe 640 and the cartridge on the circuit board 40 are set as in the above-described embodiment. The contact state between the side terminal group 400 and the contact mechanism 70 can be kept good.

・ Modification 3:
In the embodiment and the modification, the maximum widths W1 to W5 of each part satisfy the inequality (1). On the other hand, for example, the maximum width W3 of the prism 270 may be set regardless of the maximum width of other portions. That is, the maximum width W3 of the prism 270 may not satisfy the inequality (1).

  Further, when the first surface 201 of the cartridge 20 is viewed from the −Z-axis direction toward the + Z-axis direction, the maximum width of each part is satisfied if both of the following two conditions (A) and (B) are satisfied. May not satisfy the inequality (1). Therefore, for example, as long as both of the following two conditions (A) and (B) are satisfied, the maximum width W4 of the circuit board 40 is wider than the maximum width W1 of the second cartridge side regulating portion 220. Also good. Further, the maximum width W1 of the second cartridge side regulating portion 220 may be wider than the maximum width W2 of the printing material supply port 280.
