This application claims priority from Japanese Patent Application No. 2018-064181 filed Mar. 29, 2018. The entire content of the priority application is incorporated herein by reference.
The present disclosure relates to a liquid cartridge storing liquid therein, and a system including the liquid cartridge, and an attachment section to which the liquid cartridge is attachable.
One conventional system known in the art includes an ink cartridge, and an inkjet recording device. The inkjet recording device includes attachment section, and the ink cartridge can be mounted into and extracted from the attachment section. The attachment section of the inkjet recording device includes contacts.
A circuit board may be provided at an ink cartridge (see Japanese Patent Application Publication No. 2013-049164, for example). Memory is mounted on the circuit board for storing such information as a color and material composition of ink stored in the cartridge, a residual quantity of ink, and the like. Electrodes are also formed on the circuit board. Electrical connections are formed between the electrodes on the ink cartridge and the contacts in the attachment section when the ink cartridge is mounted in the attachment section, enabling the inkjet recording device to read information stored in the memory.
However, as the functionality of circuit boards continues to improve, the number of components mounted on the circuit boards has increased. For example, batteries and other components are now being mounted on these circuit boards in addition to memory. Such additions increase the size of the circuit board. As a consequence, enlarged parts of the circuit board are susceptible to contacting the attachment section and becoming damaged as the ink cartridge is being mounted into the attachment section.
In view of the foregoing, it is an object of the present disclosure to provide a liquid cartridge capable of reducing a potential for damage to a circuit board. It is another object of the present invention to provide a system including this liquid cartridge.
In order to attain the above and other objects, according to one aspect, the present disclosure provides a liquid cartridge configured to be inserted into an attachment portion of a printing device in an insertion direction crossing a gravitational direction and attached to the attachment portion in an upright posture, the attachment portion including a contact. The liquid cartridge includes a liquid chamber storing liquid therein, a liquid passage, a substrate, a contact and a memory. The liquid passage is in communication with the liquid chamber and extends frontward in the insertion direction from the liquid chamber. The substrate has a first surface and a second surface opposite to each other. The first surface includes a first region and a second region. The first region faces upward in the upright posture, and the second region is positioned lower than the first region in the upright posture. The contact of the cartridge is formed on the first region of the first surface. The contact of the cartridge is electrically connectable to the contact of the device. The memory is electrically connected to the contact of the device and is mounted on the substrate at a position lower than the contact of the cartridge in the upright posture.
The above liquid cartridge may further include an electronic component electrically connected to the memory and configured to supply power to the memory. In this case, the electronic component may be any types of electronic components or elements that can serve as means for supplying power to the memory. For example, the electronic component may be a battery or a capacitor in a charged state.
According to another aspect, the present disclosure also provides a system including the above liquid cartridge and an attachment portion of a printing device. The liquid cartridge is configured to be inserted into the attachment portion in an insertion direction and is attached to the attachment portion in an upright posture. The attachment portion includes: a holder defining an internal space therein for accommodating the liquid cartridge in the upright posture; a tube provided at the holder and connectable to the liquid passage of the liquid cartridge; and a connector. The holder includes: a bottom wall; an upper wall spaced apart from the bottom wall in a height direction parallel to the gravitational direction in the upright posture; and a pair of side walls each connecting the bottom wall and the upper wall, the side walls being spaced apart from each other in a widthwise direction orthogonal to the height direction and the insertion direction, the upper wall, the bottom wall and the pair of side walls defining the internal space. The connector includes: a contact disposed at the upper wall and configured to contact the contact of the liquid cartridge in the attached state; a first wall having a first lower end in the height direction, the first lower end being positioned lower than the contact of the device in the height direction; and a second wall spaced apart from the first wall in the insertion direction, the second wall having a second lower end in the height direction, the second lower end being positioned lower than the contact of the device in the height direction. The contact of the device is positioned between the first wall and the second wall in the insertion direction. The second region of the substrate is separated from one of the first lower end and the second lower end in the height direction in the attached state of the liquid cartridge.
According to still another aspect, the present disclosure also provides a liquid cartridge configured to be inserted into an attachment portion of a printing device in an insertion direction crossing a gravitational direction and attached to the attachment portion in an upright posture, the attachment portion including a contact. The liquid cartridge includes a liquid chamber storing liquid therein, a liquid passage, a substrate, a contact and a memory. The liquid passage is in communication with the liquid chamber and extends frontward in the insertion direction from the liquid chamber. The substrate has a first surface and a second surface opposite to each other. The first surface includes: a first region facing upward in the upright posture; a second region positioned lower than the first region in the upright posture; and a third region positioned rearward in the insertion direction relative to the second region in the upright posture, the third region being positioned higher than the second region in the upright posture. The contact of the cartridge is formed on the first region of the first surface and is electrically connectable to the contact of the device. The memory is electrically connected to the contact of the cartridge. The memory is mounted at one of the second surface and the third region.
In the drawings:
Hereinafter, an embodiment of the disclosure will be described in detail while referring to accompanying drawings. It would be apparent to those skilled in the art that the embodiment described below is merely an example of the present disclosure and modifications and variations may be made therein without departing from the scope of the disclosure.
<Overview of Printer 10>
As shown in
The ink cartridges 30 are inserted into the cartridge-attachment portion 110 through the opening 112 in order to be attached to the cartridge-attachment portion 110. The ink cartridges 30 are also extracted from the cartridge-attachment portion 110 through the opening 112.
In the following description, as shown in
Further, in the following description, the frontward direction 51 and rearward direction 52 are collectively referred to as a front-rear direction, the upward direction 54 and downward direction 53 are collectively referred to as a vertical direction, and the rightward direction 55 and leftward direction 56 are collectively referred to as a left-right direction.
In the state where the ink cartridge 30 is completely attached to the cartridge-attachment portion 110, the ink cartridge 30 has a height in the up-down direction; a depth in the front-rear direction (i.e., in the insertion direction); and a width in the left-right direction (i.e., widthwise direction).
When the ink cartridge 30 is in its upright posture, the width direction of the ink cartridge 30 corresponds to the left-right direction, the height direction of the ink cartridge 30 corresponds to the vertical direction, and the depth direction of the ink cartridge 30 corresponds to the front-rear direction.
While in its upright posture, the ink cartridge 30 is inserted forward into the cartridge-attachment portion 110 through the opening 112 (see
The ink cartridge 30 stores ink that the printer 10 can use for printing. As shown in
The printer 10 also includes a sheet tray 15, a feed roller 23, a conveying path 24, a pair of conveying rollers 25, a platen 26, a pair of discharge rollers 27, and a discharge tray 16. The feed roller 23 feeds each of the sheets from the sheet tray 15 onto the conveying path 24, and the conveying rollers 25 convey the sheet over the platen 26. The recording head 21 ejects ink onto the sheet as the sheet passes over the platen 26, whereby an image is recorded on the sheet. The discharge rollers 27 receive the sheet that has passed over the platen 26 and discharge the sheet into the discharge tray 16 provided on a downstream end of the conveying path 24.
<Cartridge-Attachment Portion 110>
As shown in
<Cartridge Holder 101>
The cartridge holder 101 shown in
As shown in
The opening 112 is formed in a rear end of the cartridge holder 101 to oppose the end wall 57 in the front-rear direction. The opening 112 is in communication with the interior space 104 of the cartridge holder 101. A user faces the opening 112 when using the printer 10.
The interior space 104 of the cartridge holder 101 is defined by the end wall 57, bottom wall 59, top wall 58, and side walls 60. Partitioning walls (not shown) partition the interior space 104 into four compartments. One each of the tubes 102, tanks 103, optical sensors 113, protruding parts 114, and connector 130 is provided in each compartment of the partitioned interior space 104. Note that the number of compartments in the interior space 104 is not limited to four.
<Tubes 102>
The tube 102 shown in
The tube 102 has an interior space 102A. A valve 115 and a coil spring 116 are accommodated in the interior space 102A. By moving in the front-rear direction, the valve 115 opens and closes an opening 102B formed in the distal end of the tube 102. The coil spring 116 urges the valve 115 rearward. Hence, when an external force is not being applied to the valve 115 (when the ink cartridge 30 is not mounted in the cartridge-attachment portion 110), the valve 115 closes the opening 102B. Further, when an external force is not being applied to the valve 115, a rear end of the valve 115 urged by the coil spring 116 protrudes rearward from the opening 102B.
Notches (not shown) are formed in a peripheral wall of the tube 102 at the distal end thereof, and specifically in a portion of the peripheral wall positioned rearward from a part of the valve 115 that closes the opening 102B, i.e., a front end of the valve 115.
<Shaft 145>
As shown in
<Cover 111>
As shown in
<Tanks 103>
As shown in
Note that the cartridge-attachment portion 110 need not be provided with the tanks 103. In this case, the front ends of the tubes 102 communicate with the recording head 21 via the ink tubes 20 without passing through the tanks 103.
<Optical Sensors 113>
As shown in
The optical sensors 113 is configured to output detection signals to a controller 1 (see
<Cover Sensor 118>
The cover sensor 118 is disposed on the cartridge holder 101 near the top edge of the opening 112. The cover sensor 118 includes a light-emitting part and a light-receiving part. When the cover 111 is in the closed position, a part of the cover 111 is disposed in an optical path of the light traveling from the light-emitting part toward the light-receiving part, blocking the light from reaching the light-receiving part in the cover sensor 118. Accordingly, the cover sensor 118 outputs a low level signal to the controller 1. When the cover 111 is not in the closed position, that is, when the cover 111 is in a position separated from the cover sensor 118, the cover 111 does not interrupt light traveling from the light-emitting part to the light-receiving part, and the cover sensor 118 outputs a high level signal to the controller 1.
<Protruding Parts 114>

As shown in
The case 131 supports the contacts 132 in the corresponding internal spaces formed by the slots 135. The contacts 132 are configured of members that are flexible and electrically conductive. Bottom ends 132A of the contacts 132 protrude farther downward than the bottom surface 131A of the case 131. The bottom ends 132A of the contacts 132 can be elastically deformed upward.
Top ends 132B of the contacts 132 (see
The case 131 also includes a rear wall 136, a front wall 137, a right wall 138, and a left wall 139. The rear wall 136, front wall 137, right wall 138, and left wall 139 protrude downward from the bottom surface 131A of the case 131. Bottom edges of the rear wall 136, front wall 137, right wall 138, and left wall 139 are thus positioned lower than bottom edges of the contacts 132. Note that one or more of the rear wall 136, front wall 137, right wall 138, and left wall 139 may be omitted from the case 131.
The rear wall 136 is positioned farther rearward than the bottom ends 132A of the contacts 132. The front wall 137 is positioned farther forward than the bottom ends 132A of the contacts 132. The rear wall 136 and front wall 137 are aligned with each other in the front-rear direction. The right wall 138 is positioned farther rightward than the bottom ends 132A of the contacts 132, and the left wall 139 is positioned farther leftward than the bottom ends 132A of the contacts 132. The right wall 138 and left wall 139 are aligned with each other in the left-right direction. A front edge of the right wall 138 is connected to a right edge of the front wall 137, and a rear edge of the right wall 138 is connected to a right edge of the rear wall 136. A front edge of the left wall 139 is connected to a left edge of the front wall 137, and a rear edge of the left wall 139 is connected to a left edge of the rear wall 136.
<Ink Cartridge 30>
The ink cartridge 30 shown in
As shown in
<Housing 31>
The housing 31 is configured of a front wall 40, a rear wall 41, a top wall 39, a bottom wall 42, and a pair of side walls 37 and 38. The front wall 40 and rear wall 41 are separated from each other in the front-rear direction. The top wall 39 is arranged between the front wall 40 and rear wall 41 and extends from a top edge of the front wall 40 to a top edge of the rear wall 41. The bottom wall 42 is arranged between the front wall 40 and rear wall 41 and extends from a bottom edge of the front wall 40 to a bottom edge of the rear wall 41. The top wall 39 and bottom wall 42 are separated from each other in the direction of gravity. The side wall 37 and side wall 38 are separated from each other in the left-right direction. Peripheral edges of the side walls 37 and 38 are connected to the front wall 40, rear wall 41, top wall 39, and bottom wall 42.
In a state where the ink cartridge 30 is in its upright posture, a direction from the rear wall 41 to the front wall 40 is equivalent to the frontward direction 51, a direction from the front wall 40 to the rear wall 41 is equivalent to the rearward direction 52, a direction from the top wall 39 to the bottom wall 42 is equivalent to the downward direction 53, a direction from the bottom wall 42 to the top wall 39 is equivalent to the upward direction 54, a direction from the side wall 38 to the side wall 37 is equivalent to the rightward direction 55, and a direction from the side wall 37 to the side wall 38 is equivalent to the leftward direction 56. Also in this upright posture, a front surface 40A of the front wall 40 faces forward, a rear surface 41A of the rear wall 41 faces rearward, a bottom surface 42A of the bottom wall 42 faces downward, a top surface 39A of the top wall 39 faces upward, a right surface 37A of the side wall 37 faces rightward, and a left surface 38A of the side wall 38 faces leftward.
The front wall 40 is configured of a front wall 40B, and a front wall 40C positioned farther rearward than the front wall 40B. That is, a front surface of the front wall 40B and a front surface of the front wall 40C constitute the front surface 40A of the front wall 40.
The bottom wall 42 is configured of a bottom wall 42B, and a bottom wall 42C positioned higher than the bottom wall 42B. A bottom surface of the bottom wall 42B and a bottom surface of the bottom wall 42C constitute the bottom surface 42A of the bottom wall 42. The bottom wall 42C extends continuously rearward from a bottom edge of the front wall 40B. The bottom wall 42B and bottom wall 42C are joined through the front wall 40C. The bottom surface of the bottom wall 42B is positioned higher than the bottom of a cylinder 75 described later. The bottom surface of the bottom wall 42B is a sloped surface that slopes relative to the front-rear direction so that its front edge is lower than its rear edge.
The rear wall 41 is configured of an upper portion 41U, and a lower portion 41L. The upper portion 41U is positioned above the lower portion 41L. The lower portion 41L is positioned farther forward than the upper portion 41U. Both the upper portion 41U and lower portion 41L are flat surfaces. The upper portion 41U and lower portion 41L extend in directions that intersect but are not orthogonal to each other. The lower portion 41L slopes relative to the vertical direction, and specifically slopes forward from top to bottom.
Unless otherwise specified, it will be assumed that the ink cartridge 30 is in its upright posture in the following description. In other words, the vertical, front-rear, and left-right directions for the ink cartridge 30 are defined based on the ink cartridge 30 being in the upright posture.
The ink cartridge 30 has an overall flattened shape in which a left-right dimension thereof (width) is smaller than a front-rear dimension thereof (depth), and the vertical and front-rear dimensions (height and depth) are larger than the left-right dimension (width).
The ink cartridge 30 is mounted in the cartridge holder 101 by inserting the ink cartridge 30 forward through the opening 112 formed in the cartridge holder 101 of the cartridge-attachment portion 110 and is removed from the cartridge holder 101 by pulling the ink cartridge 30 rearward through the opening 112.
As shown in
In the housing 31, at least the rear wall 41 has a light-transmission capability so that a level of ink stored in the storage chamber 32 is visible from the outside.
The housing 31 includes the cylinder 75 that protrudes forward from the front surface of the front wall 40C. The cylinder 75 is elongated in the front-rear direction. A passage 75A extending in the front-rear direction is formed inside the cylinder 75. That is, the direction in which the cylinder 75 and passage 75A extend (front-rear direction) is aligned with the insertion direction of the ink cartridge 30. An opening 75B is formed in a front end of the cylinder 75 and in communication with the passage 75A. The passage 75A has a rear end in communication with the storage chamber 32. That is, the passage 75A is open at its rear end on the front surface of the front wall 40C. In other words, the passage 75A is open frontward at the front wall 40. Hence, the passage 75A penetrates the front wall 40.
The passage 75A accommodates a valve 79, and a coil spring 80. The valve 79 opens and closes the opening 75B by moving in the front-rear direction. The coil spring 80 urges the valve 79 rearward. Therefore, when an external force is not applied to the valve 79, the valve 79 firmly contacts the sealing member 76 fitted in the opening 75B. However, when an external force is applied to the valve 79, the valve 79 separates from the sealing member 76, allowing ink stored in the storage chamber 32 to be supplied through the passage 75A and out through the opening 75B in the cylinder 75. Note that a structure for switching opening and closing of the opening 75B is not limited to the structure configured of the valve 79. For example, the opening 75B may be closed by a seal adhered to the cylinder 75.
An air communication port 140 is formed in the top wall 39 of the housing 31. A seal 141 seals the air communication port 140 prior to the ink cartridge 30 being inserted into the cartridge-attachment portion 110. The seal 141 can be peeled off the air communication port 140. By peeling the seal 141 off the air communication port 140 before inserting the ink cartridge 30 into the cartridge-attachment portion 110, the storage chamber 32 is able to communicate with the external air via the air communication port 140. Note that communication between the storage chamber 32 and external air may be achieved through means not involving peeling off the seal 141. For example, a valve may be provided in the air communication port 140, and the valve may be used to switch communication between the storage chamber 32 and the outside air on and off.
The front wall 40, rear wall 41, top wall 39, bottom wall 42, and side walls 37 and 38 may be configured of a plurality of walls in the same manner as the front wall 40 in the embodiment, or may be configured of single walls in the manner of the rear wall 41.
Further, the surfaces of the ink cartridge 30 including the front surface 40A of the front wall 40, rear surface 41A of the rear wall 41, top surface 39A of the top wall 39, bottom surface 42A of the bottom wall 42, right surface 37A of the side wall 37, and left surface 38A of the side wall 38 need not be formed as single flat surfaces.
The front surface 40A of the front wall 40 is a surface of the housing 31 that is visible when viewing the ink cartridge 30 in its upright posture from the front side. According to a concept of the present disclosure, a front surface includes: a surface of the housing 31 positioned farthest forward (the front surface 40A); and a surface positioned forward of a halfway point in the front-rear direction between the forwardmost surface and a rearmost surface of the housing 31 (the rear surface 41A).
The rear surface 41A of the rear wall 41 is a surface of the housing 31 that is visible when viewing the ink cartridge 30 in its upright posture from the rear side. The concept of a rear surface in the present disclosure includes: a surface of the housing 31 positioned farthest rearward (the rear surface 41A); and a surface positioned rearward of the halfway point in the front-rear direction between the rearmost surface and the forwardmost surface of the housing 31 (front surface 40A).
The top surface 39A of the top wall 39 is a surface of the housing 31 that is visible when viewing the ink cartridge 30 in its upright posture from above. The concept of the top surface in the present disclosure includes: a topmost surface of the housing 31 (the top surface 39A); and a surface above a vertical halfway point between this topmost surface and a bottommost surface of the housing 31 (the bottom surface 42A).
The bottom surface 42A of the bottom wall 42 is a surface of the housing 31 that is visible when viewing the ink cartridge 30 in its upright posture from below. The concept of the bottom surface in the present disclosure includes: the bottommost surface of the housing 31 (the bottom surface 42A); and a surface below the vertical halfway point between this bottommost surface and the topmost surface of the housing 31 (the top surface 39A).
The right surface 37A of the side wall 37 is a surface of the housing 31 that is visible when viewing the ink cartridge 30 in its upright posture from the right side.
The left surface 38A of the side wall 38 is a surface of the housing 31 that is visible when viewing the ink cartridge 30 in its upright posture from the left side.
<Sealing Member 76>
The sealing member 76 shown in
The sealing member 76 is prevented from coming out of the cylinder 75 by well-known means. For example, the sealing member 76 may be fixed in the cylinder 75 by interposing the sealing member 76 between the cylinder 75 and a cap (not shown) placed over the cylinder 75, or may be fixed in the cylinder 75 by adhesive.
<Protruding Part 43>
As shown in
The protruding part 43 also includes a horizontal surface 154 that extends continuously forward from the lock surface 151. The horizontal surface 154 expands in both the left-right and front-rear directions. The protruding part 43 also includes a sloped surface 155 that is forward of and continuous with the horizontal surface 154. The sloped surface 155 slopes relative to the front-rear direction, and specifically slopes downward toward the front.
The protruding part 43 also includes a positioning surface 89. The positioning surface 89 is formed frontward of the sloped surface 155. The positioning surface 89 faces upward.

<Circuit Board 64>
As shown in
The circuit board 64 includes the substrate 63, a memory 66, a battery 68, and electrodes 65. The circuit board 64 is positioned rearward of the projection 67 and forward of the protruding part 43. The circuit board 64 is also positioned farther rearward than the sealing member 76 in the front-rear direction. More specifically, the circuit board 64 is positioned farther rearward than the through-hole 76A formed in the sealing member 76. The circuit board 64 is also positioned below the virtual plane X described above in the vertical direction. The storage chamber 32 is vertically interposed between the circuit board 64 and the bottom surface 42A of the bottom wall 42.
The substrate 63 of the circuit board 64 is a flexible substrate formed of a plastic film or the like. The circuit board 64 is configured by mounting the memory 66 and battery 68 on the substrate 63 and forming four electrodes 65 on the substrate 63 (see
Note that the number of electrodes 65 is determined based on the number of the contacts 132 in the cartridge-attachment portion 110 (see
The substrate 63 has a length in the front-rear direction that is greater than a width thereof in the left-right direction. Preferably, the front-rear dimension of the substrate 63 is at least two times greater than the left-right dimension, and more preferably at least three times greater than the left-right dimension. Note that the front-rear dimension of the substrate 63 may be less than two times the left-right direction or even less than or equal to the left-right dimension.
The substrate 63 has a first surface 61, and a second surface 62. The first surface 61 is exposed to the outside of the ink cartridge 30. The second surface 62 is a surface opposite the first surface 61 and is fixed to the top surface 39A of the top wall 39 of the housing 31.
The substrate 63 is bonded to the top surface 39A with a photopolymer. However, the circuit board 64 may be bonded to the top surface 39A with an adhesive other than a photopolymer or may be mounted on the top surface 39A by means other than adhesives, such as thermal caulking. Note that when thermal caulking is used to mount the circuit board 64 on the top surface 39A, each of the four corners of the circuit board 64 is preferably fixed to the top surface 39A; that is, each of the right-front corner, left-front corner, right-rear corner, and left-rear corner in a plan view. However, it should be obvious that the positions subjected to the thermal caulking need not be limited to these four corners.
The substrate 63 extends into the recess 83 from a position forward of the recess 83. The second surface 62 follows the shape of the recess 83 on the top surface 39A. With this arrangement, the first surface 61 of the substrate 63 is divided into a first region 61A, a second region 61B, and a step 61C.
The first region 61A constitutes a portion of the first surface 61 positioned forward of the recess 83. The first region 61A faces at least upward. Specifically, the first region 61A in the present embodiment faces in a direction directly opposite the direction of gravity when the ink cartridge 30 is in the upright posture. The first region 61A extends in both front-rear and left-right directions. Note that the first region 61A may extend in directions inclined relative to the front-rear and left-right directions.
The second region 61B is a portion of the first surface 61 extending in the front-rear direction along the bottom of the recess 83. The second region 61B is positioned lower than and rearward of the first region 61A. The second region 61B extends along a bottom surface 83B defining the recess 83. The second region 61B faces at least upward. Specifically, in the present embodiment, the second region 61B faces in the direction directly opposite the direction of gravity when the ink cartridge 30 is in the upright posture. The second region 61B extends in both front-rear and left-right directions. Note that the second region 61B may extend in directions inclined relative to the front-rear and left-right directions.
The step 61C is a portion of the first surface 61 between the first region 61A and second region 61B. The step 61C extends along a side surface 83A defining the recess 83. In other words, the step 61C defines part of the recess 83. A top edge of the step 61C is continuous with a rear edge of the first region 61A, while a bottom edge of the step 61C is continuous with a front edge of the second region 61B. Hence, the second region 61B is connected to the first region 61A via the step 61C. The step 61C faces at least rearward. Specifically, the step 61C in the present embodiment faces in a direction opposite the insertion direction when the ink cartridge 30 is in its upright posture. Note that the step 61C may extend in directions sloped relative to the front-rear and left-right directions.
A plurality of electrodes (not shown) is formed on the second surface 62 of the substrate 63 at a region opposite the second region 61B of the first surface 61. The memory 66 is positioned on some of these electrodes. The battery 68 is positioned on the electrodes that the memory 66 is not mounted on. Hence, the memory 66 and battery 68 are mounted on the second surface 62 of the substrate 63 at the region opposite the second region 61B of the first surface 61.
Here, a depression 84 is formed in the bottom surface 83B of the recess 83 at a region corresponding to the region in which the memory 66 and battery 68 are mounted. In other words, the memory 66 and battery 68 mounted on the second surface 62 are positioned in the depression 84.
The memory 66 stores information related to the ink cartridge 30 that can be read by the controller 1 of the printer 10. The information related to the ink cartridge 30 is data specifying a lot number, a manufactured date, an ink color, and the like. The memory 66 may be a semiconductor memory, such as a Static RAM (SRAM). Note that an integrated circuit (IC) providing function(s) other than a memory may also be mounted on the substrate 63, if necessary.
The battery 68 is a button-shaped battery (button cell) in the present embodiment. The battery 68 is positioned rearward of the memory 66. In other words, the battery 68 is mounted at a position separated farther away from the first region 61A than the memory 66 is from the first region 61A in the front-rear direction. The electrodes on which the battery 68 is mounted are connected to the electrodes on which the memory 66 is mounted. With this structure, the battery 68 is electrically connected to the memory 66, whereby the battery 68 is configured to supply electricity to the memory 66. Upon receipt of the power supply from the battery 68, the memory 66 (SRAM) can store various data.
Note that, instead of the battery 68, an electronic component other than the battery 68 may be mounted on the substrate 63 for supplying power to the memory 66. For example, a capacitor in a charged state can be employed as another example of the electronic component for supplying power to the memory 66.
As shown in
The memory 66 and battery 68 are mounted on the second surface 62 at positions lower than the electrodes 65 formed on the first region 61A of the first surface 61 in the upright posture.
<Operations for Attaching the Ink Cartridge 30 to the Cartridge-Attachment Portion 110>
Next, operations for mounting the ink cartridge 30 in the cartridge holder 101 of the cartridge-attachment portion 110 will be described.
In a state where the ink cartridge 30 is not attached to the cartridge-attachment portion 110, no member is positioned between the light-emitting part and light-receiving part of the optical sensor 113, enabling light to travel from the light-emitting part to the light-receiving part. At this time, the optical sensor 113 outputs a high level detection signal to the controller 1 (see
In order to attach the ink cartridge 30 to the cartridge-attachment portion 110, the ink cartridge 30 is inserted forward into the cartridge holder 101 through the opening 112 of the cartridge-attachment portion 110 (see
As the ink cartridge 30 is inserted forward into the cartridge holder 101, as illustrated in
The tube 102 inserted into the passage 75A also contacts and pushes the valve 79 rearward. Through this action, the valve 79 is separated from the sealing member 76 against a forward urging force of the coil spring 80.
Further, when the distal end of the tube 102 contacts the valve 79, the valve 79 contacts the valve 115 from the rear side thereof and pushes the valve 115 forward. Consequently, the valve 115 moves forward against the urging force of the coil spring 116. This action allows the interior space 102A of the tube 102 to communicate with the exterior of the tube 102 through the opening 102B.
As a result, ink stored in the storage chamber 32 can flow into the tank 103 and recording head 21 via the interior space 102A of the tube 102. At this time (in the state shown in
Also, when the ink cartridge 30 is being inserted forward into the cartridge holder 101, as illustrated in
Forming the bottom wall 42 of the housing 31 as a sloped surface that slopes relative to the front-rear direction provides a space between the bottom wall 42 and an inner top surface of the bottom wall 59 of the cartridge holder 101 needed for this pivotal movement (clockwise pivot).

Further, a bottom edge of the front wall 137 is positioned lower than the electrodes 65 and higher than the second region 61B. The rear wall 136 overlaps with the second region 61B of the circuit board 64 when viewed from above. In other words, the second region 61B is aligned with the rear wall 136 in the vertical direction. A bottom edge of the rear wall 136 is positioned lower than the electrodes 65 and higher than the second region 61B. In other words, the second region 61B is vertically separated from the bottom edge of the rear wall 136.
Note that while the first region 61A, second region 61B, bottom edge of the rear wall 136, and bottom edge of the front wall 137 all extend in the horizontal direction in the present embodiment, one or more of the first region 61A, second region 61B, bottom edge of the rear wall 136, and bottom edge of the front wall 137 may extend in a direction sloped relative to the horizontal direction.
As shown in
To extract the ink cartridge 30 from the cartridge holder 101 of the cartridge-attachment portion 110, the user pushes the operating surface 92 downward. As shown in
<Detecting Attachment of the Ink Cartridge 30 to the Cartridge-Attachment Portion 110>
Next, operations for detecting when an ink cartridge 30 is inserted into the cartridge-attachment portion 110 will be described with reference to flowcharts shown in
The flowcharts of
As shown in
In a case where the cover 111 is not in the closed position (S10: NO), the controller 1 repeats the determination in S10 until the cover 111 is determined to be closed, i.e., until the signal outputted from the cover sensor 118 changes from high level to low level.
When the cover 111 is determined to be in the closed position (S10: YES), in S20 the controller 1 determines whether the memory 66 on the circuit board 64 of the ink cartridge 30 is accessible, i.e., whether the controller 1 can read from or write to the memory 66. When the contacts 132 are in contact with and electrically connected to the electrodes 65 on the circuit board 64, the controller 1 is able to access the memory 66 on the circuit board 64. When the contacts 132 are not in contact with the electrodes 65 on the circuit board 64, the controller 1 cannot access the memory 66.
If the controller 1 cannot access the memory 66 (S20: NO), in S30 the controller 1 determines that an ink cartridge 30 is not mounted in the cartridge-attachment portion 110. In this case, the controller 1 notifies the user that an ink cartridge 30 is not mounted by displaying a message on a display panel (not shown) provided on a housing of the printer 10 and/or emitting a beep or other sound from a speaker (not shown).
However, when the controller 1 can access the circuit board 64 (S20: YES), in S40 the controller 1 determines whether the signal outputted from the optical sensor 113 to the controller 1 is high level or low level. When the projection 67 is positioned between the light-emitting part and light-receiving part of the optical sensor 113, the optical sensor 113 outputs a low level signal to the controller 1. When the projection 67 is not positioned between the light-emitting part and light-receiving part of the optical sensor 113, the optical sensor 113 outputs a high level signal to the controller 1.
When the signal outputted from the optical sensor 113 to the controller 1 is high level (S40: HIGH), in S50 the controller 1 determines that an abnormal ink cartridge 30 is attached to the cartridge-attachment portion 110. In this case, the controller 1 notifies the user that an abnormal ink cartridge 30 is mounted by displaying a message on the display panel (not shown) provided on the housing of the printer 10 and/or playing a beep or other sound from the speaker (not shown).
On the other hand, if the signal outputted by the optical sensor 113 is low level (S40: LOW), in S60 the controller 1 determines that a normal ink cartridge 30 is attached to the cartridge-attachment portion 110.
In the flowchart of
However, the controller 1 may be configured to determine whether an ink cartridge 30 is mounted in the cartridge-attachment portion 110 based on the level of the signal outputted from the optical sensor 113 and to determine whether the ink cartridge 30 mounted in the cartridge-attachment portion 110 is normal based on whether the circuit board 64 is accessible. Steps in this variation will be described next with reference to the flowchart in
Referring to
When the controller 1 determines in S110 that the cover 111 is in the closed position (S110: YES), in S120 the controller 1 determines whether the signal outputted from the optical sensor 113 to the controller 1 is high level or low level.
If the signal outputted by the optical sensor 113 is high level (S120: HIGH), in S130 the controller 1 determines that an ink cartridge 30 is not mounted in the cartridge-attachment portion 110. In this case, as in S30 of
However, if the signal outputted by the optical sensor 113 is low level (S120: LOW), in S140 the controller 1 determines whether the circuit board 64 of the ink cartridge 30 is accessible.
If the controller 1 cannot access the circuit board 64 (S140: NO), in S150 the controller 1 determines that an abnormal ink cartridge 30 is mounted in the cartridge-attachment portion 110. In this case, as in S50 of
On the other hand, if the controller 1 can access the circuit board 64 (S140: YES), in S160 the controller 1 determines that a normal ink cartridge 30 is mounted in the cartridge-attachment portion 110.
According to the described embodiment, the second region 61B constituting the first surface 61 of the substrate 63 is positioned lower than the first region 61A. That is, the memory 66 mounted on the second surface 262 at a region opposite the second region 61B is positioned lower than the electrodes 65 formed on the first region 61A. Accordingly, this arrangement reduces a potential for the second region 61B (memory 66 and battery 68) to contact the cartridge-attachment portion 110 as the ink cartridge 30 is being inserted into the cartridge-attachment portion 110.
Further, if the cartridge-attachment portion 110 contacts the top of the ink cartridge 30, such contact is less likely to impinge negative impact to the memory 66 and battery 68, since the memory 66 and battery 68 are disposed on the second surface 62 at the region lower than the first region 61A (opposite to the second region 61B).
In the present embodiment, the single flexible substrate 63 can provide a stepped structure along the recess 83 formed on the top surface 39A of the top wall 39.
Since the substrate 63 of the embodiment is a flexible substrate, the substrate 63 may deflect if contacted by the cartridge-attachment portion 110 while the ink cartridge 30 is being inserted into the cartridge-attachment portion 110. Hence, this configuration can reduce the potential for damage to the substrate 63 and components mounted on the substrate 63, such as the memory 66 and battery 68.
Since the lock surface 151 that can contact the shaft 145 of the cartridge-attachment portion 110 is higher than the electrodes 65 in the embodiment, the shaft 145 is also positioned higher than the electrodes 65. Accordingly, the electrodes 65 are unlikely to contact the shaft 145 while the ink cartridge 30 is being inserted into the cartridge-attachment portion 110.
Further, the electrodes 65 are elongated in the front-rear direction in the depicted embodiment. Therefore, even if the position of the ink cartridge 30 in the cartridge-attachment portion 110 in the front-rear direction varies in the state where the ink cartridge 30 is attached to the cartridge-attachment portion 110, this configuration can reduce a potential for the electrodes 65 losing contact with the contacts 132.
According to the structure of the embodiment, the second region 61B can be prevented from contacting the rear wall 136 and front wall 137 of the connector 130 in the cartridge-attachment portion 110 while the ink cartridge 30 is being inserted into the cartridge-attachment portion 110.
In the depicted embodiment, the cartridge-attachment portion 110 contacts the rubber sealing member 76 prior to contacting the circuit board 64 during the process of attaching the ink cartridge 30 to the cartridge-attachment portion 110. This contact reduces a speed at which the ink cartridge 30 is inserted and can soften the force of impact with the circuit board 64.
In the depicted embodiment, the memory 66 and battery 68 are mounted on the second surface 62 of the substrate 63 at the region opposite the second region 61B of the first surface 61 (see
For example, in the embodiment described above, the battery 68 is mounted at a position separated farther than the memory 66 from the first region 61A in the front-rear direction (see
Still alternatively, for example, the memory 66 and battery 68 may be mounted on the second surface 62 of the substrate 63 at a region opposite the first region 61A of the first surface 61 (see
In the embodiment described above, the memory 66 and battery 68 are mounted on the second surface 62 of the substrate 63 at the region opposite the second region 61B of the first surface 61 (see
The substrate 63 is not limited to the shape shown in
The third region 261D is a portion of the first surface 261 that is positioned rearward of the recess 83 in the front-rear direction. The third region 261D is aligned with the first region 261A in the front-rear direction, as illustrated in
The step 261E is a portion of the first surface 261 between the second region 261B and the third region 261D. The step 261E extends along a side surface 283C defining a recess 283 corresponding to the recess 83 of the embodiment. A top edge of the step 261E is continuous with a front edge of the third region 261D, and a bottom edge of the step 261E is continuous with a rear edge of the second region 261B. Hence, the third region 261D is connected to the rear edge of the second region 261B through the step 261E.
Note that, in the second modification, the recess 283 is defined by: a side surface 283A corresponding to the side surface 83A; a bottom surface 283B constituting a bottom of the recess 283; and the side surface 283C. These surfaces 283A, 283B and 283C belong to a top surface 239A of the top wall 239 of the housing 231. The step 261C extends along the side surface 283A; the second region 261B extends along the bottom surface 283B; and the step 261E extends along the side surface 283C.
The memory 66 and battery 68 are mounted on the second surface 262 of the substrate 263 at a region opposite the third region 261D of the first surface 261. A depression 284 corresponding to the depression 84 of the embodiment is formed in the top wall 239 to accommodate the memory 66 and battery 68 therein.
Note that the memory 66 and battery 68 can be mounted at various positions, such as those described in the first modification (for example, on the second surface 262 of the substrate 263 at regions opposite the first region 261A, the second region 261B, the step 261C, or the step 261E of the first surface 261; and on the second region 261B, the step 261C, the third region 261D, or the step 261E constituting the first surface 61 of the substrate 63). The memory 66 and battery 68 mounted on the third region 261D of the first surface 261 are depicted with dashed lines in
When the ink cartridge 30 having the structure shown in
The structure according to the second modification can reduce the possibility of the second region 261B contacting the cartridge-attachment portion 110 as the ink cartridge 30 is being inserted into the cartridge-attachment portion 110.
Further, in the second modification, the memory 66 is provided on the second surface 62 at a position opposite the third region 261D that is separated from the second region 261B, which in turn is separated from the first region 261A. Thus, the memory 66 is arranged at a position separated away from the electrodes 65. Accordingly, the portion of the first surface 61 on the side opposite the memory 66 (i.e., the third region 261D) is unlikely to collide with the contacts 132 on the cartridge-attachment portion 110 that connect with the electrodes 65.
In the depicted embodiment, the second region 61B of the first surface 61 on the substrate 63 is positioned rearward of the first region 61A. However, the second region 61B may instead be positioned forward of the first region 61A.
Specifically,
In the third modification, the second region 361B of the first surface 361 is positioned forward of and lower than the first region 361A. The second region 361B is also positioned rearward of the projection 67.
The step 361C extends along a step surface 339B positioned between the positioning surface 89 and projection 67. The step surface 339B is a vertical surface constituting a portion of a top surface 339A of the top wall 339 of the housing 331. A top edge of the step 361C is continuous with a front edge of the first region 361A, while a bottom edge of the step 361C is continuous with a rear edge of the second region 361B.

Further, as in the second modification of the embodiment, the first surface 361 of the substrate 363 in the third modification may also include portion corresponding to the third region 261D and step 261E, in addition to the first region 361A, second region 361B, and step 361C.
Specifically,
The ink cartridge 430 includes a housing 431 and a circuit board 464 fixed to a top wall 439 of the housing 431.
In the ink cartridge 430 shown in
The circuit board 464 of this modification includes a substrate 463 having a first surface 461 and a second surface 462.
The first surface 461 includes: a first region 461A corresponding to the first region 361A; a second region 461B corresponding to the second region 361B; a step 461C corresponding to the step 361C; a third region 461D corresponding to the third region 261D; and a step 461E corresponding to the step 261E.
The second region 461B extends along the bottom surface 485A defining the recess 485.
The third region 461D is a portion of the first surface 461 that is positioned forward of the recess 485 in the front-rear direction. The third region 461D is also positioned higher than the second region 461B and lower than the first region 461A. Alternatively, the third region 461D may be at the same vertical position as the first region 461A.
The step 461E is a portion of the first surface 461 positioned between the second region 461B and third region 461D. The step 461E extends along the side surface 485B defining the recess 485. A top edge of the step 461E is continuous with a rear edge of the third region 461D, while a bottom edge of the step 461E is continuous with a front edge of the second region 461B. Hence, the third region 461D is connected to the front edge of the second region 461B via the step 461E.

The structure shown in
In the embodiment described above, the substrate 63 is a flexible substrate. However, at least part of the substrate 63 may be configured of a rigid substrate formed of glass epoxy or the like.
As an example,
Referring to
In the substrate 563, an upper surface 561A of the first substrate 563A, a rear part on the upper surface 561B1 of the second substrate 563B1 and a front part on the upper surface 561B2 of the second substrate 563B2 constitute a first surface 561 of the substrate 563. Further, a lower surface of the second substrate 563B1, a lower surface of the second substrate 563B2 and a center part on the lower surface of the first substrate 563A constitute a second surface 562 of the substrate 563.
In the fourth modification, the first surface 561 on the first substrate 563A (i.e., the upper surface 561A of the first substrate 563A) constitutes a first region 561A corresponding to the first region 61A of the embodiment. In other words, the electrodes 65 are formed on the first surface 561 of the first substrate 563A. The first surface 561 belonging to the second substrates 563B1 and 563B2 (i.e., the upper surface 561B1 of the second substrate 563B1 and the upper surface 561B2 of the second substrate 563B2) constitutes a second region 561B corresponding to the second region 61B of the embodiment.

In
When the ink cartridge 630 having the structure shown in
In the arrangement of this variation, the second region 661B can be easily formed by the second substrate 663B.
An ink cartridge 730 according to this variation includes a housing 731 and a circuit board 764 fixed to a top wall 739 of the housing 731. The circuit board 764 includes a substrate 763 configured of a rigid first substrate 763A, and a flexible second substrate 763B. In other words, just part of the substrate 763 is configured of a rigid substrate.

The memory 66 is mounted on the lower surface of the first substrate 763A (on the second surface 762). The memory 66 is accommodated in a depression 784 formed in the top surface 739A of the top wall 739. The battery 68 is mounted on the lower surface of the second substrate 763B (on the second surface 762). Here, the mounted positions of the memory 66 and battery 68 may not limited to the positions shown in
When the ink cartridge 730 having the structure shown in
In the embodiment described above, the second region 61B of the substrate 63 is lower than the rear wall 136 and front wall 137 when the ink cartridge 30 is being inserted into the cartridge holder 101 and when the ink cartridge 30 is in the attached state in the cartridge holder 101. Hence, the second region 61B of the substrate 63 does not contact the rear wall 136 and front wall 137. However, the substrate 63 may be configured so that at least a portion of the second region 61B contacts the rear wall 136 and front wall 137 and bends during the insertion process and in the attached state.
For example,
In the structure shown in
Alternatively,
In the structure shown in
In the structures shown in
Still alternatively, the substrate 63 of the embodiment may be arranged in a bent state. For example,
Here, an upper surface of the substrate 1063 constitutes a first surface 1061, while a lower surface of the substrate 1063 constitutes a second surface 1062. In the first surface 1061, a front portion other than the bent portion on the first surface 1061 (upper surface) of the substrate 1063 serves as a first region 1061A in this variation. The rear portion on the upper surface of the substrate 1063 (i.e., the bent portion accommodated in the recess 1086) serves as a second region 1061B on the first surface 1061. The second region 1061B is aligned with the first region 1061A in the frontward direction 51 in the upright posture.
In the structure shown in
For example, the memory 66 and battery 68 may be arranged as depicted in
Each of the substrates 863, 963 and 1063 has flexibility, at least partially. Hence, the substrates 863, 963 and 1063 of the fifth modification can easily be formed in a shape having low potential for contacting the cartridge-attachment portion 110, by bending the portion having flexibility, for example, as in the structure shown in
Further, when the ink cartridge 830, 930 according to the fifth modification is being inserted into the cartridge-attachment portion 110, the flexible portion of the second region 861B, 961B can be deflected when contacted by the cartridge-attachment portion 110, thereby reducing the potential for damage to this deformable portion.
Further, if the ink cartridge 830, 830′, 930 according to the fifth modification is inserted farther than expected into the cartridge-attachment portion 110 during the insertion process, components of the cartridge-attachment portion 110 may come into contact with the second region 861B, 961B of the substrate 863, 963. However, the structure of the fifth modification can reduce a potential for damage to the second region 861B, 961B, since the second region 861B, 961B can deform, at least partially, when contacted by the cartridge-attachment portion 110.
Still further, in the structures of
If the second region 861B, 961B contacts the rear wall 136 or front wall 137 in the cartridge-attachment portion 110 while the ink cartridge 830, 830′, 930 according to the fifth modification is being inserted into the cartridge-attachment portion 110, the portion of the second region 861B, 961B that contacts the rear wall 136 or front wall 137 can deform, thereby reducing a potential for damage to this deformable portion.
In the embodiment and the modifications described above, communication between the passage 75A and the outside of the cylinder 75 is switched on and off with the valve 79. However, the opening 75B may be sealed with a seal rather than the valve 79. Specifically, the seal is affixed to the front surface of the cylinder 75 before the ink cartridge 30 is inserted into the cartridge-attachment portion 110, thereby sealing off the through-hole 76A from the outside. Hence, ink in the storage chamber 32 does not flow through the passage 75A and out of the ink cartridge 30 through the through-hole 76A. When the ink cartridge 30 is inserted into the cartridge-attachment portion 110, the tube 102 punctures the seal, breaking the hermetic seal.
In the embodiment described above, the ink cartridge 30 is pivoted inside the cartridge holder 101 while being inserted therein. However, the ink cartridge 30 need not be pivoted or tilted inside the cartridge holder 101 during the insertion process. For example, if the rear wall 136 is omitted from the connector 130 of the cartridge-attachment portion 110, the ink cartridge 30 can be inserted into the cartridge holder 101 in the front-rear direction without being pivoted. The rear wall 136 must be omitted from the connector 130 in this configuration, because the first region 61A of the substrate 63 could contact the rear wall 136 of the connector 130 during the insertion process if the ink cartridge 30 were inserted into the cartridge holder 101 in the front-rear direction with no pivotal movement.
In the embodiment described above, the ink cartridge 30 is fixed in position in the front-rear direction by the lock surface 151 contacting the shaft 145 from the front side thereof. However, the positioning means for the ink cartridge 30 is not limited to this contact between the lock surface 151 and shaft 145. For example, the ink cartridge 30 may be fixed in the front-rear direction through sliding resistance between the positioning surface 89 of the ink cartridge 30 and the bottom surface on the protruding part 114 of the cartridge-attachment portion 110, and sliding resistance between the bottom surface 42A of the ink cartridge 30 and the inner top surface on the bottom wall 59 of the cartridge-attachment portion 110. Alternatively, the ink cartridge 30 may be fixed in the front-rear direction through sliding resistance between the sealing member 76 of the ink cartridge 30 and the tube 102 of the cartridge-attachment portion 110, for example.
The structure of the ink cartridge 30 is not limited to those shown in

Further, the housing of the liquid cartridge of the disclosure may not necessarily be configured as a single member, but may be configured of a plurality of members assembled to each other. Likewise, the top wall of the housing may not necessarily be configured of a single member but may be configured of a plurality of members assembled to each other. That is, the substrate of the disclosure may be supported by an upper wall configured of more than one member.
Still further, in the depicted embodiment and various modifications, the substrate is bonded to the top surface of the top wall of the housing, i.e., directly supported by the top wall of the housing. Alternatively, the substrate of the present disclosure may be supported indirectly by the top wall of the housing, through a separate member or even through a plurality of members.
In the depicted embodiment, ink is described as an example of liquid, but the liquid cartridge may store a liquid other than ink, such as a pretreatment liquid that is ejected onto sheets or the like prior to ink during a printing operation, or water for cleaning the recording head 21.
It should be apparent to those who skilled in the art that the embodiment, various modifications thereto and variations described above may be combined with one another as appropriate.
The ink cartridges 30, 230, 330, 430, 530, 630, 730 and 1130 are an example of a liquid cartridge. The cartridge-attachment portion 110 is an example of an attachment portion. The printer 10 is an example of a printing device. The storage chamber 32 is an example of a liquid chamber. The passages 75A and 1175A are an example of a liquid passage.
