Description

The present invention relates to a consumable material cartridge which has a main body for holding a consumable material and which is mounted on an apparatus.

A liquid cartridge is known that includes a main body that stores a liquid and a substrate (for example, a rigid substrate or a flexible substrate) arranged on the upper surface of the main body (Patent Document 1). The substrate has electrodes on its surface. Notches and holes are formed in the substrate. A pair of protrusions is formed on the upper surface of the main body. The substrate is located on the upper surface of the main body with the pair of protrusions penetrating the notch and the hole. The substrate is fixed to the main body by thermally melting the tips of the pair of protrusions.

JP, 2013-129173, A

In the above liquid cartridge, the notch and the hole are formed at one end of the substrate in the predetermined direction. That is, one end of the substrate in the predetermined direction is fixed to the main body, while the other end of the substrate in the predetermined direction is not fixed to the main body. Therefore, the other end of the substrate in the predetermined direction may be flipped up and peeled off from the main body.

An object of the present invention is to provide a consumable material cartridge in which the substrate is hard to be peeled off from the main body.

(1) The consumable material cartridge according to the present invention is mounted on the device. The consumable material cartridge includes a main body that holds the consumable material, a substrate, and an adhesive that bonds the main body and the substrate. The main body includes a support base and a first contact portion. The substrate connects a surface facing the first direction, a back surface parallel to the surface and supported by the support, an electrode formed on the surface, the front surface and the back surface, and facing each other. A first side surface and a second side surface. At least a part of the first side surface is exposed to the outside of the consumable material cartridge. The second side surface is in contact with the first contact portion. The adhesive includes an end portion near a first side of a boundary between the first side surface and the back surface in an overlapping region where the support base and the back surface overlap with each other in the viewpoint along the first direction. Located in one area. It is not located in the second area different from the first area in the overlapping area.

Usually, a portion of the substrate exposed to the outside of the consumable material cartridge is more likely to receive a force from the outside than a portion not exposed (for example, a portion adhered to the consumable material cartridge). Therefore, the portion of the substrate exposed to the outside of the consumable material cartridge 30 is easily peeled off from the support base. According to the above configuration, the back surface of the substrate is in contact with the adhesive in the first region near the first side of the boundary between the first side surface exposed to the outside of the consumable material cartridge and the back surface. The second side surface of the substrate, which is opposite to the first side surface, is in contact with the first contact portion of the main body. The board is positioned by contacting the first contact portion. That is, the position where the substrate is bonded to the main body and the position where the substrate is positioned are aligned in a certain straight line. More specifically, the first region and the first contact portion are arranged in a straight line. As a result, a portion of the substrate that is likely to receive a force generated from the outside (specifically, the first region near the first side of the boundary between the first side surface and the back surface) is adhered to the main body. Does not come off easily from the body. In addition, even if an external force is generated toward the bonded portion of the substrate, the substrate can receive the above force by the first contact portion of the main body. Therefore, the substrate is unlikely to shift in the direction of the force. This makes it more difficult for the substrate to separate from the main body.

(2) The adhesive is located in a third region of the overlapping region that includes an end of the boundary between the second side surface and the back surface near the second side. The area of the first region is larger than the area of the third region.

According to the above configuration, the substrate is bonded to the support base in the two regions, the first region and the third region. Therefore, as compared with the case where the substrate is adhered to only one of the first region and the third region, the substrate can be firmly adhered to the support base. Further, according to the above configuration, the area of the first region is larger than the area of the third region. That is, it is possible to increase the adhesive area of the portion that is easily subjected to the force from the outside and firmly bond the portion, while narrowing the adhesive area of the portion that is less likely to receive the force from the outside and use a small amount of adhesive.

(3) The substrate includes an integrated circuit and a potting portion that projects on the back surface in a second direction opposite to the first direction and accommodates the integrated circuit. The main body includes a concave portion that is recessed from the support base in the second direction and into which a part of the potting portion enters. The second region includes a fourth region in which the back surface and the concave portion overlap with each other in a viewpoint along the first direction.

The potting section contains an integrated circuit. Therefore, when the adhesive is in contact with the potting portion, the potting portion is deformed due to contraction or expansion of the adhesive, and the integrated circuit is also affected. On the other hand, according to the above configuration, the potting portion is not in contact with the adhesive. Therefore, it is possible to prevent the potting portion from being deformed by the adhesive. Further, since the adhesive is not in contact with the periphery of the potting portion, it is possible to prevent the substrate around the potting portion from being deformed.

(4) The substrate includes an integrated circuit and a potting portion that projects in the second direction opposite to the first direction on the back surface and accommodates the integrated circuit. The main body includes a concave portion that is recessed from the support base in the second direction and into which a part of the potting portion enters. The second region passes through a point closest to the first side in the fourth region where the back surface and the recess overlap with each other in the viewpoint along the first direction and is parallel to the first side. And a fifth region between the line and a second imaginary line that passes through a point closest to the second side in the fourth region and is parallel to the second side.

According to the above configuration, similarly to (3), it is possible to reduce the possibility of damage to the substrate and prevent deformation of the substrate.

(5) For example, the first region is a region closer to the first side than the fourth region.

(6) For example, the adhesive is located in a third region including an end portion of the boundary between the second side surface and the back surface near the second side in the overlapping region, and the third region is The area is closer to the second side than the fourth area.

(7) The adhesive is a photocurable resin. The recess extends in the third direction along the back surface. From the viewpoint along the third direction, at least one of both ends of the recess along the third direction is exposed to the outside of the consumable material cartridge.

According to the above configuration, it is possible to irradiate the adhesive with light through the end of the exposed recess. Thereby, the adhesive can be cured.

(8) The substrate includes a third side surface that connects the front surface and the back surface and intersects the first side surface and the second side surface. The main body includes a second contact portion that contacts the third side surface.

According to the above configuration, the substrate can be positioned in the two directions intersecting with each other by the first contact portion and the second contact portion. Since the two directions intersecting with each other are parallel to the surface, the orientation and position of the electrodes are appropriately maintained in the two directions.

(9) The first region is a boundary between the second side surface and the back surface at both end points of a portion of the third side of the boundary between the third side surface and the back surface that contacts the second contact portion. Is a region closer to the first side than a third virtual line that passes through the end point farther from the second side and is parallel to the second side.

According to the above configuration, the first region is separated from the first contact portion and the second contact portion. Therefore, it is possible to prevent the adhesive contacting the back surface in the first region from protruding from between the substrate and the first contact portion and the second contact portion.

(10) The substrate includes a fourth side surface that is located opposite to the third side surface with respect to the electrode and is not adjacent to the third side surface. The first region includes an end portion of the boundary between the fourth side surface and the back surface, which is closer to the fourth side, of the overlapping region.

A portion of the substrate that is not in contact with the first contact portion and the second contact portion is not protected by the first contact portion and the second contact portion, and thus is easily peeled off from the support base. According to the above configuration, it is possible to firmly bond the end portions of the substrate, which are not in contact with the first contact portion and the second contact portion, near the first side and the fourth side. This makes it difficult for the substrate to peel off from the support.

(11) The overlapping area is rectangular. The first region is a region at both ends of the overlapping region in the direction along the first side. The second region is a region including an end portion of the boundary between the second side surface and the back surface near the second side in the overlapping region, and is a region of both end portions in a direction along the second side. is there.

According to the above configuration, the substrate can be firmly adhered to the support base with a small amount of adhesive.

(12) For example, the main body further includes a supply port that communicates the inside and the outside of the main body and through which a consumable material supplied to the device passes. The supply port is a direction in which the consumer goods cartridge is attached to the device, is orthogonal to an orthogonal direction orthogonal to the first direction, and is closer to the orthogonal direction than a center position in the orthogonal direction. It is located away. The substrate is located away from the center position in the orthogonal direction and is located away from the supply port in the first direction.

According to the present invention, it is possible to prevent the substrate from peeling off from the main body.

The four needles 102, the four lock pins 145, and the four electrode units 160 are arranged in the left and right directions 55 and 56, respectively. The four needles 102, the four lock pins 145, and the four electrode units 160 have the same configuration. Therefore, in the following, for simplification of description, only the configurations of one needle 102, one lock pin 145, and one electrode unit 160 will be described.

The case 101 shown in FIG. 2 has a box shape having a top surface 115, a bottom surface 116, a front surface 117, and an opening 112. The top surface 115 partitions the top of the internal space of the case 101. The bottom surface 116 partitions the bottom of the internal space of the case 101. The front surface 117 partitions the front end of the internal space of the case 101. Further, the front surface 117 connects the top surface 115 and the bottom surface 116. The opening 112 opens the rear end of the internal space of the case 101. That is, the user inserts or withdraws the consumable material cartridge 30 into or from the case 101 through the opening 112.

The case 101 includes guides 108 and 109 on the top surface 115 and the bottom surface 116. The lower surfaces 42 and 142 of the consumable material cartridge 30 contact the guide 108, and the upper surface 39 contacts the guide 109. As a result, the consumable material cartridge 30 moves in the case 101 along the front-rear directions 51 and 52 by the guides 108 and 109. The case 101 includes three plates 191. The three plates 191 divide the internal space of the case 101 into four long spaces in the vertical directions 53 and 54. Each of the spaces partitioned by the plate 191 accommodates one consumable material cartridge 30.

[Needle 102]
As shown in FIG. 1, the needle 102 is made of tubular resin. The needle 102 projects in the rearward direction 52 from an opening 193 (see FIG. 2) below the front surface 117 of the case 101. The needle 102 is located at a position corresponding to the supply pipe 34 of the consumable material cartridge 30 attached to the case 101.

The electrode unit 160 has four electrodes. These four electrodes extend at least downward. The four electrodes are located at positions corresponding to the four electrodes 65 (see FIGS. 3 and 5) mounted on the upper surface of the substrate 64. The four electrodes are arranged in the left-right direction 55, 56. The number of electrodes and the number of electrodes 65 of the electrode unit 160 are not limited to four and are arbitrary.

Each electrode of the electrode unit 160 is electrically connected to the control unit 1 of the device 10 via an electric circuit. The control unit 1 is composed of, for example, a CPU, a ROM, a RAM and the like. By electrically connecting the four electrodes of the electrode unit 160 and the four electrodes 65, respectively, a voltage is applied to the electrode 65, the electrode 65 is grounded, or data is transmitted to the electrode 65. As a result, the control unit 1 can access the data stored in the integrated circuit mounted on the board 64.

The supply pipe 34 is located below the front surface 40 of the inner frame 35. The supply port 71 is located at the rear end of the supply pipe 34.

The consumable material in the consumable material cartridge 30 is supplied to the apparatus 10 through the supply port 71. That is, the consumable material supplied to the apparatus 10 passes through the supply port 71. The supply port 71 extends along an imaginary plane along the up-down directions 53, 54 and the left-right directions 55, 56. That is, the supply port 71 is orthogonal to the front-rear directions 51 and 52. The supply port 71 is open in the front-rear direction 51, 52. The supply port 71 is located in front of an intermediate position between the front end and the rear end of the consumable material cartridge 30 in the front-rear directions 51 and 52. In other words, the supply port 71 is located in front of the center position of the consumable material cartridge 30 in the front-rear directions 51 and 52. More specifically, the supply port 71 is located between the front surface 140 and the rear surface 41 in the front-rear directions 51 and 52, and is closer to the front surface 140 than the rear surface 41.

The supply pipe 34 has one end located inside the internal frame 35 and the other end located outside the internal frame 35. That is, one end of the supply pipe 34 communicates with the storage chamber 36. The other end of the supply pipe 34 communicates with the outside of the consumable material cartridge 30 through the supply port 71.

As described above, in the process of inserting the consumable material cartridge 30 into the case 101 in the front direction 51, the needle 102 enters the internal space of the supply pipe 34 via the supply port 71. As a result, the needle 102 and the supply pipe 34 are connected. The consumable material stored in the storage chamber 36 can flow out to the tube 20 (outside the consumable material cartridge 30) through the internal space of the supply pipe 34 and the internal space of the needle 102. The consumable material flowing out into the tube 20 is supplied to the recording head 21 of the apparatus 10.

The upper surface 39 and the lower surface 42 are located apart from each other in the vertical directions 53 and 54. The rear portion of the inner frame 35 is located inside the rear cover 31. That is, the rear cover 31 covers the rear portion of the inner frame 35.

The convex portion 43 is located on the upper surface 39 of the rear cover 31. The convex portion 43 extends along the front-rear direction 51, 52 at the center of the left-right direction 55, 56 on the upper surface 39. The surface of the convex portion 43 facing the rearward direction 52 is the lock surface 151. The lock surface 151 extends along the vertical directions 53 and 54. The lock surface 151 is a surface that can contact the lock pin 145 in the rearward direction 52 when the consumable material cartridge 30 is mounted on the case 101. When the lock surface 151 contacts the lock pin 145, the consumable material cartridge 30 mounted in the case 101 is held in the case 101.

The rear cover 31 has an operation section 90 on the upper surface 39 thereof. The operation unit 90 is located behind the lock surface 151. In order to take out the consumable material cartridge 30 from the state where the consumable material cartridge 30 is attached to the case 101, the user operates the operation unit 90. More specifically, in order to take out the consumable material cartridge 30, the user pushes the operation unit 90 downward. When the user operates the operation unit 90, the convex portion 43 moves downward. As a result, the lock surface 151 is located below the lock pin 145. As a result, the consumable material cartridge 30 mounted in the case 101 can be taken out.

[Front cover 32]
As shown in FIGS. 3 and 4, in the front cover 32, the right side surface 143, the left side surface 144, the upper surface 141, and the lower surface 142 extend from the front surface 140 in the rearward direction 52. The front cover 32 has a box shape having an opening, and the cross section of the opening is orthogonal to the front-rear directions 51 and 52. The right side surface 143 and the left side surface 144 are located apart from each other in the left-right directions 55 and 56. The upper surface 141 and the lower surface 142 are located apart from each other in the vertical directions 53 and 54. The front portion of the inner frame 35 is located inside the front cover 32. That is, the front cover 32 covers the front portion of the inner frame 35 that is not covered by the rear cover 31.

The sub-upper surface 146 located in the lower direction 53 than the upper surface 141 is located in the front direction 51 than the upper surface 141 of the front cover 32. A support base 130, which will be described later, is located on the sub upper surface 146. A pair of side walls 147 and 148 project in the upward direction 54 from the right end and the left end of the sub upper surface 146. The pair of side walls 147, 148 are provided with a recess 149 recessed downwardly 53 from their upper surfaces.

The front cover 32 is provided below the front surface 140 thereof with a hole 97 penetrating in the front-rear direction 51, 52. The supply pipe 34 is located inside the hole 97 when the inner frame 35 is located inside the front cover 32. That is, the supply pipe 34 is exposed to the outside of the consumable material cartridge 30 through the hole 97 of the front cover 32. The position, size, and shape of the hole 97 correspond to the supply pipe 34 of the inner frame 35.

[Substrate 64]
As shown in FIG. 3, the support base 130 supports the substrate 64 in an adhered state. Details of the support 130 and the bonding of the substrate 64 will be described later.

The substrate 64 is located in front of the consumable material cartridge 30. That is, the substrate 64 is located in front of the intermediate position between the front end and the rear end of the consumable material cartridge 30 in the front-rear directions 51 and 52. In other words, the substrate 64 is located in front of the central position of the consumable material cartridge 30 in the front direction 51 and the rear direction 52. Further, the substrate 64 is located above the consumable material cartridge 30. That is, the substrate 64 is located above the supply port 71. More specifically, the substrate 64 is located between the front surface 140 and the rear surface 41 in the front-rear directions 51 and 52. Further, the substrate 64 is located on the front cover 32 in the front-rear direction 51, 52, the front surface 140 being closer than the rear surface 41. The substrate 64 is located above the front cover 32, that is, above the hole 97 (in other words, the supply port 71).

As shown in FIG. 5, the substrate 64 is a rectangular parallelepiped, and has a front surface 64B, a back surface 64A, four side surfaces (first side surface 64E, second side surface 64F, third side surface 64D, and fourth side surface 64C). Equipped with. Each of the surfaces 64A, 64B, 64C, 64D, 64E, 64F has a rectangular shape.

The surface 64B faces the upward direction 54. The back surface 64A is located behind the front surface 64B and faces the downward direction 53. The front surface 64B and the back surface 64A extend along the front-rear directions 51, 52 and along the left-right directions 55, 56. That is, the front surface 64B and the back surface 64A are parallel to each other.

The first side surface 64E, the second side surface 64F, the third side surface 64D, and the fourth side surface 64C connect the front surface 64B and the back surface 64A.

The first side surface 64E faces the front direction 51. The second side surface 64F faces the rearward direction 52. That is, the first side surface 64E and the second side surface 64F face each other in the front-rear directions 51 and 52. The first side surface 64E and the second side surface 64F extend along the up-down directions 53, 54 and the left-right directions 55, 56.

The third side surface 64D faces the left direction 56. The fourth side surface 64C faces the right direction 55. That is, the third side surface 64D and the fourth side surface 64C face each other in the left-right directions 55 and 56. The third side surface 64D and the fourth side surface 64C extend along the front-rear direction 51, 52 and along the up-down direction 53, 54.

The first side surface 64E and the second side surface 64F intersect the third side surface 64D and the fourth side surface 64C.

The substrate 64 is, for example, COB (chip on board). The substrate 64 may be COF (chip on film), which is a flexible flexible substrate, rather than a so-called rigid substrate having high rigidity. As shown in FIGS. 5B and 5C, an integrated circuit (not shown) is mounted on the back surface 64A of the substrate 64. On the back surface 64A, a potting agent such as epoxy resin, urethane resin, or silicone resin protects the integrated circuit. The potting agent and the integrated circuit are hereinafter referred to as a potting section 67. As a result, on the back surface 64A, the potting portion 67 is supported by the back surface 64A so as to project downward from the back surface 64A. The integrated circuit has a memory for storing information about the consumable material cartridge 30, for example, data indicating lot number, manufacturing date, color of consumable material, and the like.

As shown in FIG. 5A, the substrate 64 has four electrodes 65 on its surface 64B. Each electrode 65 is electrically connected to the integrated circuit. Each electrode 65 extends along the front-rear direction 51, 52 and is separated from each other in the left-right direction 55, 56. Each electrode 65 is exposed to the outside of the consumable material cartridge 30 on the surface 64B so as to be electrically connectable. The four electrodes 65 are, for example, a clock electrode, a data electrode, a power supply voltage electrode, a ground electrode, etc., respectively. The four electrodes 65 are electrically connected to each of the four electrodes formed on the electrode unit 160 when the consumable material cartridge 30 is mounted on the case 101.

The four electrodes 65 are located between the first side surface 64E and the second side surface 64F in the front-rear directions 51 and 52. The first side surface 64E and the second side surface 64F are not adjacent to each other in the front-rear directions 51 and 52. The four electrodes 65 are located between the third side surface 64D and the fourth side surface 64C in the left-right direction 55, 56. The third side surface 64D and the fourth side surface 64C are not adjacent to each other in the left-right directions 55 and 56.

The fourth side surface 64</b>C is exposed to the outside of the consumable material cartridge 30 when the support base 130 supports the substrate 64. The front part and the rear part of the third side surface 64D are in contact with the second wall 132, which will be described later, and the second contact part 1320 thereof. A portion between the front portion and the rear portion of the third side surface 64D is exposed to the outside of the consumable material cartridge 30 through an opening 133 of the support base 130 described later.

As shown in FIG. 3, when the support base 130 supports the substrate 64, the entire first side surface 64</b>E is exposed to the outside of the consumable material cartridge 30. Note that only a part of the first side surface 64E may be exposed to the outside of the consumable material cartridge 30. The second side surface 64F is in contact with the first wall 131 described below and the first contact portion 1310 thereof.

As shown in FIG. 5B, the first side 181 that is the boundary between the back surface 64A and the first side surface 64E constitutes the long side of the rectangular back surface 64A. The second side 182, which is the boundary between the back surface 64A and the second side surface 64F, constitutes the long side of the rectangular back surface 64A. The third side 183, which is the boundary between the back surface 64A and the third side surface 64D, constitutes the short side of the rectangular back surface 64A. The fourth side 184, which is the boundary between the back surface 64A and the fourth side surface 64C, constitutes the short side of the rectangular back surface 64A.

[Support 130]
The support base 130 includes an upper surface 134, a first wall 131, and a second wall 132. As shown in FIGS. 3 and 4, the support base 130 is located on the sub upper surface 146. The support base 130 projects upward from the sub upper surface 146. The support base 130 is located between the recesses 149 formed in the pair of side walls 147 and 148 in the left-right direction 55 and 56. As shown in FIG. 3, the support base 130 supports the substrate 64 from below by contacting the back surface 64</b>A of the substrate 64.

As shown in FIG. 4, the support base 130 has an upper surface 134 facing the upward direction 54. The upper surface 134 includes a first support surface 103, a second support surface 104, and a concave surface 105. The first support surface 103, the second support surface 104, and the concave surface 105 are located above the sub upper surface 146.

The first support surface 103 and the second support surface 104 extend along the front-rear direction 51, 52 and the left-right direction 55, 56. The first support surface 103 is located in front of the second support surface 104. The first support surface 103 is located at a position apart from the second support surface 104 in the front-rear directions 51 and 52. The heights of the first supporting surface 103 and the second supporting surface 104 in the vertical directions 53 and 54 are substantially the same. The first support surface 103 supports the front portion of the back surface 64A of the substrate 64. The second support surface 104 supports the rear portion of the back surface 64A of the substrate 64.

A concave surface 105 is located between the first support surface 103 and the second support surface 104 in the front-rear directions 51 and 52. The concave surface 105 has a curved surface that curves downward. That is, the concave surface 105 has a shape that is recessed in a direction in which the first supporting surface 103 and the second supporting surface 104 support the substrate 64 downwardly. The space defined by the concave surface 105 is the concave portion 106. The recessed portion 106 follows the curved surface of the recessed surface 105 and is recessed downward. As shown in FIG. 5C, at least part of the potting portion 67 of the substrate 64 has entered the recess 106 in the state where the support base 130 supports the substrate 64. That is, the recess 106 accommodates the potting portion 67 of the substrate 64. The concave surface 105 does not come into contact with the potting portion 67 of the substrate 64 when the potting portion 67 has entered the concave portion 106.

As shown in FIG. 4, the front cover 32 includes a first wall 131. The first wall 131 projects upward behind the second support surface 104. As shown in FIG. 3, the first wall 131 is in contact with the second side surface 64F of the substrate 64 supported by the support base 130 at the first contact portion 1310 thereof.

As shown in FIG. 4, the front cover 32 includes two second walls 132. The two second walls 132 project upward from the left ends of the first support surface 103 and the second support surface 104, respectively. An opening 133 exists between the two second walls 132 in the front-rear direction 51, 52. The concave surface 105 is exposed to the outside of the consumable material cartridge 30 through the opening 133. That is, when viewed from the left direction 56, the left end of the recess 106 is exposed to the outside of the consumable material cartridge 30. The right end of the recess 106 is also exposed to the outside of the consumable material cartridge 30. As shown in FIG. 3, the two second walls 132 are in contact with the third side surface 64D of the substrate 64 supported by the support base 130 at the second contact portion 1320 thereof.

As shown in FIG. 3, the front end of the substrate 64 is positioned in front of the support base 130 when the support base 130 supports the substrate 64. More specifically, the front end of the substrate 64 is located in front of the front end of the first support surface 103. Then, on the substrate 64, the sub upper surface 146 is located below the portion protruding forward of the front end of the first support surface 103 with a space in the vertical directions 53 and 54. In addition, this space|interval is a space|interval (for example, about 1.0 mm-2.0 mm) which a nail|claw of a person or a minus driver can enter, for example.

[Adhesion of Substrate 64 to Support 130]
A part of the back surface 64A of the substrate 64 is bonded to the support base 130. The adhesives 120 and 121 bond the substrate 64 and the front cover 32 together. Specifically, as shown in FIG. 5C, the adhesive 120 is interposed between the first support surface 103 of the support base 130 and the back surface 64A of the substrate 64. As a result, the substrate 64 is bonded to the first support surface 103 of the support base 130. The adhesive 121 is interposed between the second support surface 104 of the support base 130 and the back surface 64A of the substrate 64. As a result, the substrate 64 is bonded to the second support surface 104 of the support base 130. The adhesives 120 and 121 are, for example, acrylic photo-curable resins. The photocurable resin is, for example, a resin that cures when irradiated with ultraviolet rays. As described above, the first support surface 103 and the second support surface 104 support the substrate 64 in an adhered state.

The adhesive 120 is applied to the entire surface of the first support surface 103. Further, the adhesive 121 is applied to a part of the surface of the second support surface 104. Here, the area of the adhesive 120 is larger than the area of the adhesive 121 in the viewpoints along the vertical directions 53 and 54. The adhesive 120 may be applied to a part of the first support surface 103, or the entire surface of the second support surface 104, provided that the area of the adhesive 120 is larger than the area of the adhesive 121. The adhesive 121 may be applied to the.

The concave surface 105 of the support base 130 is not in contact with the back surface 64A of the substrate 64. That is, the concave surface 105 does not support the substrate 64.

Hereinafter, as shown in FIG. 6, the back surface 64A of the substrate 64 will be described by being divided into an overlapping region and a region other than the overlapping region. The overlapping region is a region where the back surface 64A of the substrate 64 and the support base 130 overlap with each other in the viewpoints along the vertical directions 53 and 54. In FIG. 6, this overlapping area is an area surrounded by a broken line, and the overlapping area is specifically a rectangle. Areas other than the overlapping area are areas not surrounded by broken lines in FIG. That is, the area other than the overlapping area is a portion of the substrate 64 located in front of the front end of the support base 130 (that is, the dashed line in the most front).

Further, in the following, the overlapping area will be described by being divided into a first area 171, a second area 172, a third area 173, and a fourth area 174.

The first region 171 is a part of the back surface 64A. The first area 171 is an area in contact with the adhesive 120. In other words, the first area 171 is an area where the adhesive 120 is located. That is, the first region 171 is a region that overlaps the region of the first support surface 103 coated with the adhesive 120 (the entire surface of the first support surface 103) in the viewpoints along the vertical directions 53 and 54. In FIG. 6, the first region 171 is hatched. The first region 171 includes a front end portion of the overlapping region near the first side 181. Here, the front end part is a part in front of a fourth region 174 described later, and is a part including the front end of the support base 130 (that is, a broken line located at the frontmost position).

The third region 173 is a part of the back surface 64A. The third region 173 is a region in contact with the adhesive 121. In other words, the third region 173 is a region where the adhesive 121 is located. That is, the third region 173 is a region that overlaps with the region of the second support surface 104 coated with the adhesive 121 (a part of the surface of the second support face 104) in the viewpoints along the vertical directions 53 and 54. Is. In FIG. 6, the third region 173 is hatched. The third region 173 includes a rear end portion of the overlapping region near the second side 182. Here, the rear end portion is a portion rearward of a fourth region 174, which will be described later, and a portion including the rear end of the support base 130 (that is, the rearmost dashed line). The area of the second support surface 104 coated with the adhesive 121 is the central portion of the second support surface 104 in the left-right direction 55, 56, but the area is not limited to the central portion. The area of the third region 173 is smaller than the area of the first region 171 in the viewpoint along the vertical directions 53 and 54.

The second region 172 is a part of the back surface 64A. The second area 172 is an area that is not in contact with the adhesives 120 and 121. In other words, the second area 172 is an area where the adhesives 120 and 121 are not located. That is, the second area 172 is an area different from the first area 171 and the second area 172 in the overlapping area. In FIG. 6, the second region 172 is not hatched.

The fourth region 174 is a part of the back surface 64A. The fourth region 174 is a region in which the back surface 64A and the recess 106 overlap each other in the viewpoint along the vertical directions 53 and 54. The fourth area 174 is an area around the potting portion 67 and its surroundings. The fourth area 174 is a part of the second area 172. The adhesive 120, 121 is not located in the fourth region 174. The first region 171 is a region closer to the first side 181 than the fourth region 174 in the front-rear directions 51 and 52. That is, the first area 171 is located in front of the fourth area 174. The third region 173 is a region closer to the second side 182 than the fourth region 174 in the front-rear directions 51 and 52. That is, the third region 173 is located behind the fourth region 174.

[How to attach the substrate 64]
Hereinafter, a method of attaching the substrate 64 to the support base 130 will be described. The substrate 64 is adhered to the support base 130 with adhesives 120 and 121 which are photocurable resins.

First, the worker applies the adhesives 120 and 121 to predetermined portions of the first support surface 103 and the second support surface 104. Specifically, the operator applies the adhesive 120 to the entire surface of the first support surface 103 and the adhesive 121 to a part of the surface of the second support surface 104. The part of the surface of the second support surface 104 is specifically the central portion in the left-right direction 55, 56. Next, the operator places the substrate 64 on the support base 130. At this time, the operator positions the potting portion 67 of the substrate 64 in the recess 106 of the support 130, brings the second side surface 64F of the substrate 64 into contact with the first contact portion 1310, and the third side surface of the substrate 64. 64D is brought into contact with the second contact portion 1320. As a result, the support base 130 supports the substrate 64 in a state where the first contact portion 1310 of the first wall 131 and the second contact portion 1320 of the second wall 132 position the substrate 64.

Next, the operator irradiates the adhesive 120, 121 applied to the first support surface 103 and the second support surface 104 with ultraviolet rays from the right through the recess 149. As a result, the adhesives 120 and 121 are cured. As a result, the substrate 64 adheres to the support 130.

[Effect]
Usually, the portion of the substrate 64 exposed to the outside of the consumable material cartridge 30 is more likely to receive a force from the outside than the portion not exposed (for example, the portion adhered to the consumable material cartridge 30). Therefore, the portion of the substrate 64 exposed to the outside of the consumable material cartridge 30 is easily peeled off from the support base 130. According to the above-described embodiment, the back surface 64A of the substrate 64 contacts the adhesive 120 in the first area 171 near the first side 181 of the boundary between the first side surface 64E exposed to the outside of the consumable material cartridge 30 and the back surface 64A. ing. In addition, the second side surface 64F that faces the first side surface 64E of the substrate 64 is in contact with the first contact portion 1310 of the first wall 131 of the main body 33. Since the first wall 131 is aligned with the second support surface 104 in the front-rear direction 51, 52, the substrate 64 is positioned in the front-rear direction 51, 52 by contacting the first contact portion 1310. That is, the location where the substrate 64 is bonded to the main body 33 and the location where the substrate 64 is positioned are aligned in a straight line. More specifically, the first region 171 and the first contact portion 1310 are arranged in the front-rear direction 51, 52. As a result, a portion of the substrate 64 that is likely to receive a force generated from the outside (specifically, the first region 171 near the first side 181 of the boundary between the first side surface 64E and the back surface 64A) is bonded to the main body 33. Therefore, it is difficult for the substrate 64 to come off the main body 33. In addition, even if a force is generated from the outside toward the bonded portion of the substrate 64, particularly from the rear side, the substrate 64 is forced to move by the first contact portion 1310 rearward of the first region 171. You can take it. Therefore, the substrate 64 is unlikely to be displaced in the direction of the force, particularly backward. This makes it more difficult for the substrate 64 to separate from the main body 33.

Further, according to the above-described embodiment, the substrate 64 is bonded to the support base 130 in two regions, the first region 171 and the third region 173. Therefore, as compared with the case where only one of the first region 171 and the third region 173 is bonded, the substrate 64 can be firmly bonded to the support base 130. Further, according to the above embodiment, the area of the first region 171 is larger than the area of the third region 173. That is, it is possible to increase the adhesive area of the portion that is easily subjected to the external force and firmly bond the relevant portion, while narrowing the adhesive area of the portion that is less likely to receive the external force and use a small amount of the adhesive 121. ..

The potting unit 67 contains an integrated circuit. Therefore, when the adhesive is in contact with the potting portion 67, the potting portion 67 is deformed due to contraction or expansion of the adhesive, and the integrated circuit is also affected. On the other hand, according to the above-described embodiment, the potting portion 67 is not in contact with the adhesives 120 and 121. Therefore, it is possible to prevent the potting portion 67 from being deformed by the adhesive. In addition, since the adhesive does not abut around the potting portion 67, it is possible to prevent the substrate 64 around the potting portion 67 from being deformed.

Further, according to the above-described embodiment, it is possible to irradiate the adhesive with light through the exposed ends of the recesses 106. Thereby, the adhesive can be cured.

Further, according to the above-described embodiment, the board 64 can be positioned in the two directions orthogonal to each other by the first contact portion 1310 and the second contact portion 1320. Since the two directions orthogonal to each other are parallel to the front surface 64B or the back surface 64A, respectively, the orientations and positions of the four electrodes 65 are appropriately maintained in the two directions. As a result, good conduction can be realized between the four electrodes of the electrode unit 160 and the four electrodes 65 in the above two directions. In the above embodiment, one of the two directions is the front-rear direction 51, 52, and the other is the left-right direction 55, 56.

[Modification]
In the above description, the back surface 64A of the substrate 64 is in contact with the support base 130 (more specifically, the first support surface 103 and the second support surface 104) only at the front end portion and the rear end portion. However, the back surface 64</b>A may be in contact with the support base 130 at portions other than the front end portion and the rear end portion. For example, the back surface 64</b>A may be in contact with the support base 130 in all areas except the fourth area 174. Further, for example, when the integrated circuit is mounted on the front surface 64B, the back surface 64A may be in contact with the support base 130 in the entire area thereof.

Further, in the above description, as shown in FIG. 6, the back surface 64A of the substrate 64 is in contact with the adhesives 120 and 121 only at the front end portion and the rear end portion. That is, the first region 171 is a region at the front end of the back surface 64A, the third region 173 is a region at the rear end of the back surface 64A, and the second region 172 is the first region 171 and the third region 173. It was the area except. However, the first area 171, the second area 172, and the third area 173 are not limited to the areas shown in FIG. Hereinafter, modified examples of the first region 171, the second region 172, and the third region 173 will be described with reference to FIGS. 7 and 8.

In addition, in the following description, in FIGS. 7 and 8, the back surface 64</b>A is in contact with the support base 130 in all regions except the fourth region 174. Further, it is assumed that the front end of the substrate 64 is not located in front of the front end of the support table 130 when the support table 130 supports the substrate 64. That is, it is assumed that the entire back surface 64A is the overlapping area. In addition, it is assumed that only the two second walls 132 are located at the rear.

For example, as shown in FIG. 7A, the third region 173 may be omitted. In other words, the area of the third region 173 may be zero. In other words, the adhesive 121 may not be present between the second supporting surface 104 and the back surface 64A of the substrate 64. In this case, the substrate 64 is bonded to the support base 130 only at its front end portion.

Further, for example, as shown in FIG. 7B, the second region 172 may include the fifth region 170. The fifth region 170 is closest to the first imaginary line 178 passing through the point 177 closest to the first side 181 in the fourth region 174 and parallel to the second side 182, and the second side 182 in the fourth region 174. It is a region that passes through the near point 179 and is between the second virtual line 180 that is parallel to the second side 182. Note that in FIG. 7B, the second region 172 (a region that is not in contact with the adhesives 120 and 121, in other words, a region where the adhesives 120 and 121 are not located) is the same as the fifth region 170. Although it is a region, in FIGS. 6 and 7A, the second region 172 is larger than the fifth region 170. That is, the second area 172 includes the fifth area 170.

Further, for example, as shown in FIG. 7C, the first region 171 is a region closer to the first side 181 than the third virtual line 176 that passes through the end point 175 and is parallel to the second side 182. May be. That is, the first region 171 may be a region in front of the third virtual line 176, in other words, a region between the first side 181 and the third virtual line 176. The second region 172 may be a region closer to the second side 182 than the third virtual line 176. That is, the second region 172 may be a region behind the third virtual line 176, in other words, a region between the third virtual line 176 and the second side 182. Here, the end point 175 is one of the end points of the portion of the third side 183 that is in contact with the second contact portion 1320 of the second wall 132, that is, the end point that is farther from the second side 182 (that is, both ends). It is the front end point of the point).

According to the configuration shown in FIG. 7C, the first region 171 is separated from the first contact portion 1310 and the second contact portion 1320. Therefore, it is possible to prevent the adhesive 120 that comes into contact with the back surface 64A in the first region 171 from protruding from between the substrate 64 and the first wall 131 and the second wall 132.

Further, for example, as shown in FIG. 8A, the first region 171 may be the front end portion and the right end portion of the back surface 64A. That is, the first region 171 includes end portions near the first side 181 and the fourth side 184, both of which are exposed to the outside of the consumable material cartridge 30. That is, the first region 171 may include an end portion near the fourth side 184, in addition to an end portion near the first side 181.
