Description

The present invention relates to a printing-fluid cartridge having an access-providing part.

From the prior art, an ink jet recording apparatus is known which is designed to print images on recording media by ejecting ink stored in an ink cartridge through nozzles. When the ink stored in an ink cartridge runs short, a new ink cartridge is detachably inserted into such an ink jet recording apparatus.

Such an ink cartridge may be provided with a board which stores information such as a remaining amount of ink or a usage history of the cartridge. The board is electrically connected to a terminal of an image recording apparatus after the ink cartridge is attached to the image recording apparatus, thereby enabling retrieval of the stored information.

The published Japanese Patent Application No. 2011-167966 discloses an ink cartridge having a movable member and a board mounted thereon. The ink cartridge may be attached to and detached from an image recording apparatus. While the ink cartridge is attached to the image forming apparatus, the movable member is guided to the terminal from a guide pin provided in the image recording apparatus, thereby preventing electrical connection failure between the board and the terminal.

An accessible part such as a board may be accessible to the image recording device in a state where an ink cartridge is attached to the image recording device. For example, a part accessing the image recording device may fail due to a mutual connection failure, for example because of contamination of the surface of the accessing part. For example, the accessing member configured to be electrically connected to the image recording apparatus, such as the circuit board, slidably contacts a clamp of the image recording apparatus while the ink cartridge is attached to the image recording apparatus. This sliding contact with the clamp causes the surface of the accessing part to be scraped off, creating abrasion. The attrition may accumulate on the accessing part and accumulate between the accessing part and the clamp. Thus, access of the terminal to the accessing part may fail. Also, in a case where dust or ink adheres to the surface of the access providing part, access may fail. In a conventional ink cartridge having an accessing member, the accessing member faces outward from the ink cartridge. With this configuration, dust or ink may easily be adhered to the surface of the accessing part. Once abrasion has settled on the surface of the accessing part, the abrasion is difficult to remove from the surface of the accessing part.

At the same time the surface stands 93 the deepening 91 with a surface (described later) 134 of the engaging portion 130 engaged.

<Ink Needle 102 >

The ink needle 102 is formed of a resin and generally has a tubular shape. As in 7 is shown, is the ink needle 102 formed on a lower end portion of the closing wall, which is part of the housing 101 is. More precise is the ink needle 102 arranged in a position corresponding to an ink supply section 34 (described later) of the ink cartridge 30 corresponds to that in the cartridge mounting section 110 is used. The ink needle 102 protrudes from the final wall of the housing 101 backwards in front.

A cylindrically shaped guide section 105 is provided on the closing wall to the ink needle 102 to surround. The guide section 105 protrudes from the closing wall to the rear. The guide section 105 has a projecting end which is open to the rear. More precise is the ink needle 102 in a diametrical center of the guide section 105 positioned. The guide section 105 is shaped to receive a receptacle of the ink feed section 34 the ink cartridge used 30 in the leadership section 105 allows.

During the introduction of the ink cartridge 30 in the cartridge mounting section 110 in the forward direction 51 ie in the course of the action with which the ink cartridge 30 is brought into an installation position in which they in the cartridge mounting section 110 is inserted, the Tintenzufuhrabschnitt occurs 34 the ink cartridge 30 in the leadership section 105 a (see 8th ). While the ink cartridge 30 is further introduced in the forward direction, the ink needle occurs 102 into an ink supply nozzle 71 of the ink feed section 34 a (see 9 ). The ink needle 102 thus becomes with the ink supply section 34 connected so that she can communicate with him.

The rod 125 protrudes from the final wall of the housing 101 backwards in front. The rod 125 is shaped like an upper half of a cylinder. That is, the staff 125 has in a cross section along a plane which is perpendicular to the front-rear direction 51 and 52 an inverted U-shape. The rod 125 has a rib projecting upward from an uppermost portion of the inverted U-shape. The rib extends in the front-to-back direction 51 and 52 , in a state where the ink cartridge 30 at the cartridge attachment section 110 is attached, that is, when the ink cartridge 30 is in the installation position is the rod 125 in a depression (described later) 96 the ink cartridge used 30 added.

<Leg sensor 103 >

As in 7 is shown is the residue sensor 103 on the upper wall of the housing 101 at a position behind the contacts 106 arranged. The residual quantity sensor 103 has a light-emitting portion and a light-receiving portion. The light-emitting portion and the light-receiving portion are arranged to be in the right-left direction 55 and 56 opposite each other and spaced from each other. If the ink cartridge 30 at the cartridge attachment section 110 has been fastened, is a housing 62 (described later) of the ink cartridge 30 between the light-emitting portion and the light-receiving portion of the residual amount sensor 103 arranged. In other words, the light-emitting portion and the light-receiving portion are arranged to face each other with the housing 62 the attached ink cartridge 30 lies between them.

The light-emitting portion is configured to emit light in the right-left direction 55 and 56 and the light-receiving portion is configured to receive the light emitted from the light-emitting portion. The residual quantity sensor 103 is configured to output different detection signals depending on whether the light emitted from the light-emitting portion is received by the light-receiving portion. For example, the remainder sensor indicates 103 a low signal (a signal whose level is lower than a threshold value) when the light emitted from the light emitting portion is not received by the light receiving portion (ie, when an intensity of the light received at the light receiving portion decreases is as a given intensity). In contrast, there is the residual quantity sensor 103 a high level or H signal (a signal whose level is equal is high as or higher than a threshold) when the light emitted from the light emitting portion is received by the light receiving portion (ie, when the intensity of the light received at the light receiving portion is equal to or higher than the predetermined intensity) ,

<Fastening sensor 113 >

As in 7 is shown, is the mounting sensor 113 also on the upper wall of the housing 101 arranged. More precisely, the mounting sensor 113 at a position in front of the residue sensor 103 but behind the contacts 106 arranged. The mounting sensor 113 has a light-emitting portion and a light-receiving portion. The light-emitting portion is arranged to be in the right-left direction 55 and 56 the light-receiving portion is opposite and spaced from the light-receiving portion. If the ink cartridge 30 at the cartridge attachment section 110 has been attached is a first light-blocking plate 67 the attached ink cartridge 30 between the light-emitting portion and the light-receiving portion of the residual amount sensor 113 arranged. In other words, the light-emitting portion and the light-receiving portion are arranged to face each other with the first light-blocking plate 67 the ink cartridge used 30 lies between them.

The mounting sensor 113 is designed so that it depends on whether light from the light-emitting section in the right-left direction 55 and 56 is emitted or not received from the light-receiving section, outputs different detection signals. For example, the attachment sensor gives 113 a low-level signal when the light emitted from the light-emitting portion is not received by the light-receiving portion (ie, when an intensity of the light received at the light-receiving portion is less than a predetermined intensity). In contrast, the attachment sensor gives 113 a high-level signal when the light emitted from the light-emitting portion is received by the light-receiving portion (ie, when an intensity of the light received at the light-receiving portion is equal to or higher than a predetermined intensity).

More specifically, the light falling from the light-emitting portion of the mounting sensor falls 113 is emitted when the ink cartridge 30 at the cartridge attachment section 110 is attached to the first light-blocking plate 67 before it arrives at the light-receiving section. As a result, the intensity of the light received at the light-receiving portion is less than a predetermined intensity, for example, zero. Note that the first light-blocking plate 67 the light that is in the right-left direction 55 and 56 can travel, completely block or partially attenuate the light, which can break light to change its direction of travel, or completely reflect the light.

<Moving element 80 and IC board 64 >

As in 3A . 4A and 6 shown is a moving element 80 in the recess 96 intended. The moving element 80 is a substantially plate-shaped element extending from an axis 82 (please refer 6 ) extends in a direction perpendicular to the axis 82 , The axis 82 is an imaginary line parallel to the right-left direction 55 and 56 and passes through centers of a projection 81 and a projection (not shown) as described below. The moving element 80 includes a surface 83 and another surface 84 (an example of a surface) that opposes the one surface.

As in 6 is shown is the IC board 64 (an example of an electrical interface) on the one surface 83 of the movable element 80 fixed. More precisely, the IC board 64 using a known method such as gluing or fitting to the movable element 80 fixed. The IC board 64 is a hard, plate-shaped, rigid, epoxy-glass board. The IC board 64 stands during the introduction of the ink cartridge 30 in the cartridge mounting section 110 as well as when the ink cartridge 30 finally on the cartridge attachment section 110 has been fastened, with the four contacts 106 (please refer 2 ) in the right-left direction 55 and 56 are arranged in electrical contact.

As in 4A are an IC (not shown) and the four electrodes 65 (an example of accessing part) on the IC board 64 assembled. In 4A are only three of the four electrodes 65 shown while the other electrode 65 behind a right-hand wall (described later) 68 is hidden. The IC is a semiconductor integrated circuit and stores data containing information about the ink cartridge 30 specify, for example, a batch number, a production date and a color of the ink, in a readable manner.

The electrodes 65 are electrically connected to the IC. The four electrodes 65 are in the right-left direction 55 and 56 spaced apart. The electrodes 65 are aligned in the direction perpendicular to the right-left direction 55 and 56 , When the movable element 80 occupies a second, later described position, the individual electrodes extend 65 in the front-to-back direction 51 and 52 , The four electrodes 65 are so on a surface of the IC board 64 arranged that the electrodes 65 be exposed and that they can be electrically accessed from above.

As in 6 shown includes the other surface 84 of the movable element 80 a first plane surface 161 (an example of a plane surface), a second plane surface 162 and a sloping surface 163 (an example of a sloping surface). The first plane surface 161 and the second plane surface 162 extend perpendicular to the front-back direction 51 and 52 and are oriented forward when the moving element 80 occupies a first position (a position that is in 6 indicated by a solid line), which will be described later. The second plane surface 162 is closer to the axis 82 positioned as the first plane surface 161 on the axis 82 is positioned. When the movable element 80 takes the first position, is the first plane surface 161 in relation to the second plane surface 162 positioned further forward. The sloping surface 163 connects the first plane surface 161 and the second plane surface 162 , The sloping surface 163 is in relation to the first plane surface 161 and the second plane surface 162 inclined.

Note that the other surface 84 of the movable element 80 the parts described above as the first plane surface 161 and the second plane surface 162 and the sloping surface 163 does not have to have. For example, the other surface 84 of the movable element 80 only consist of a single plane surface.

As in 3A . 4A and 6 is shown, the movable element 80 from the right wall 68 , which is a right end of the recess 96 defined, and from a left wall 69 , which is a left end of the recess 96 defined, pivotally mounted.

Now is described in detail how the movable element 80 from the right wall 68 and the left wall 69 is pivoted. As in 5 shown is a hole 68A in the right wall 68 educated. A hole (not shown) is in the left wall 69 designed in such a way that the hole in the left wall 69 with the hole 68A in the right wall 68 in the right-left direction 55 and 56 flees. The moving element 80 also indicates, as in 6 is shown, a right surface from which the projection 81 projecting to the right, and a left surface from which protrudes the projection (not shown) to the left. The lead 81 the right surface and the projection of the left surface are aligned with each other in the right-left direction 55 and 56 , The moving element 80 is in the deepening 96 provided, the projection 81 the right surface in the hole 68A the right wall 68 is introduced and the projection of the left surface into the hole of the left wall 69 is introduced. With this design is the moving element 80 in relation to the ink cartridge 30 around the axis 82 swiveling in the right-left direction 55 and 56 runs.

As in 6 is shown is the movable element 80 between the first position, the in 6 is indicated by the solid line, and the second position, in 6 indicated by a dotted line, in the of arrows 88 and 89 pivoted directions.

When the movable element 80 assumes the first position, the movable element extends 80 in the up-down direction 53 and 54 , That is, each of the electrodes 65 the IC board 64 extends in the up-down direction 53 and 54 if the moving element 80 takes the first position. Here is an angle that is between a direction in which the electrodes 65 extend (ie, the top-bottom direction 53 and 54 ) and the front-to-back direction 51 and 52 (ie the horizontal direction) equals 90 degrees. Note that the angle between the direction in which the electrodes 65 extend when the movable element 80 takes the first position, and the front-back direction 51 and 52 is not equal to 90 degrees, but can be greater than zero degrees and less than or equal to 90 degrees.

When the movable element 80 the first position is the one surface 83 of the movable element 80 aligned backwards while the other surface 84 of the movable element 80 is aligned to the front. That is, when the movable element 80 the first position occupy are the electrodes 65 the IC board 64 aligned to the rear. When the movable element 80 the first position is taken by the electrodes 65 the IC board 64 under and behind the axle 82 of the movable element 80 positioned and under both the top wall 141 the front cover 32 as well as the upper wall 39 the rear cover 31 positioned.

When the movable element 80 occupies the second position, the movable element extends 80 in the front-to-back direction 51 and 52 , When the movable element 80 the second position occupies, is the one surface 83 of the movable element 80 aligned upward while the other surface 84 of the movable element 80 is oriented downwards. In the second position is a pivot end 80A (an example of a farthest portion) of the movable member 80 over the swing end 80A of the movable element 80 positioned in the first position.

In the first position, the movable element can 80 in a different direction than the up-down direction 53 and 54 extend as long as the IC board 64 is oriented substantially to the rear. Here, "substantially backward-facing" does not mean only a state in which the surface of the IC board 64 is perpendicular to the front-back direction 51 and 52 and is visible when the IC board 64 viewed from the right side, but also a condition in which the surface of the IC board 64 the front-back direction 51 and 52 cuts and is visible when the IC board 64 from the right side. For example, the mobile can element 80 extend in the first position in a direction that is in relation to the top-bottom direction 53 and 54 is inclined to do it in the right-left direction 55 and 56 considered.

In the second position, the movable element 80 in a different direction than the front-to-back direction 51 and 52 extend as long as the swivel end 80A which is furthest away from the axis 82 , above and behind the swing end 80A of the movable element 80 is positioned in the first position. For example, the movable element 80 extend in the second position in a direction with respect to the front-to-back direction 51 and 52 is inclined to do it in the right-left direction 55 and 56 considered.

<Engaging portion 130 >

As in 6 shown is a recess 129 in the lower wall 142 the front cover 32 designed so that it is deepened from above. In the recess 129 is an engaging section 130 arranged. The engaging section 130 is in relation to the case 62 a residual amount detecting section 58 (described later) arranged in front. Note that the recess 129 in the lower wall 42 instead of in the lower wall 142 could be formed when the bottom wall 42 shaped so that it continues in front of a second light-blocking plate 66 (described later).

The engaging section 130 has a contact element 131 and a coil spring 132 on.

The contact element 131 has a surface 133 and a surface 134 on. The surface 133 is in the front-to-back direction 51 and 52 inclined so that: an upper edge thereof is positioned forward with respect to a lower edge thereof; and the surface 133 is aligned forwards and downwards. The surface 134 is behind the surface 133 positioned. The surface 134 is in the front-to-back direction 51 and 52 inclined so that: an upper edge thereof is positioned rearward with respect to a lower end thereof; and the surface 134 aligned backwards and downwards.

The spiral spring 132 is with a ceiling surface 128 which the recess 129 defined, and the contact element 131 connected. Closer are from the spiral spring 132 an upper end with the ceiling surface 128 connected and a lower end with the contact element 131 connected.

When the contact element 131 with the spiral spring 132 connected, the surfaces protrude 133 and 134 of the contact element 131 in terms of the recess 129 down in front; that is, the surfaces 133 and 134 protrude in relation to the bottom wall 142 the front cover 32 downwards, when no force from the outside to the contact element 131 is created.

The surfaces 133 and 134 of the contact element 131 can by compressing the coil spring 132 in the recess 129 be recorded. The spiral spring is pushing 132 the contact element 131 downward. The surfaces 133 and 134 of the contact element 131 lie under the recess 129 when the coil spring 132 has a natural length as described above. That is, the contact element 131 can be due to compression and expansion of the coil spring 132 in the up-down direction 53 and 54 move.

<Inner frame 35 >

Although not shown in the drawings, the inner frame is 35 generally annular, with two side surfaces in the right-left direction 55 and 56 are open. The respective open surfaces of the inner frame 35 are sealed with foils (not shown) to the ink chamber 36 to store ink in the inner frame 35 train. The inner frame 35 has a front wall 40 on, which is part of the ink chamber 36 Are defined. The front wall 40 is the front wall 140 the front cover 32 facing when the inner frame 35 in the front cover 32 is housed. More precisely, the front surface of the front wall 40 a back surface (opposite the front surface) of the front wall 140 facing when the inner frame 35 in the front cover 32 is housed. The ink supply section 34 is on the front wall 40 arranged.

<Ink supply section 34 >

As in 6 is shown, the Tintenzufuhrabschnitt protrudes 34 (an example of a feeding section) from the front wall 40 of the inner frame 35 forward. The ink supply section 34 has a cylindrical outer shape and protrudes through the through hole 97 that in the front wall 140 the front cover 32 is formed, outward. That is, the ink supply section 34 is at the lower end portion of the front wall 140 positioned.

The ink supply section 34 has a cylindrically shaped tubular wall 73 defining an interior, a sealing element 76 and a cap 79 on. The sealing element 76 and the cap 79 are at the tubular wall 73 attached.

The tubular wall 73 Runs out so that they are the inside and the outside of the ink chamber 36 connects with each other. The tubular wall 73 has a rear end located in the ink chamber 36 opens. The tubular wall 73 has a front end that faces the outside of the ink cartridge 30 opens. Thus ensures the tubular wall 73 for fluid communication between the ink chamber 36 and the external environment of the ink cartridge 30 through the interior of the tubular wall 73 therethrough. The ink supply section 34 Thus, the ink that is in the ink chamber 36 is stored over the interior of the tubular wall 73 from the ink cartridge 30 deliver. The sealing element 76 and the cap 79 are at the front end of the tubular wall 73 attached.

In the interior of the tubular wall 73 are a valve 77 and a coil spring 78 accommodated. The valve 77 and the coil spring 78 serve to indicate states of the ink feed section 34 selectively between an in 9 shown state and one in 6 switch shown state. That is, in the state that is in 9 can be shown, ink from the ink chamber 36 over the interior of the tubular wall 73 from the ink cartridge 30 flow out. In the state in 6 As shown, the ink can not escape from the interior of the tubular wall 73 from the ink cartridge 30 flow out.

The valve 77 is in the front-to-back direction 51 and 52 movable to an ink supply port 71 placed in a center of the sealing element 76 is designed to open and close. The spiral spring 78 Tension the valve 77 forward. Without the application of external force, the valve closes 77 the ink supply port 71 of the sealing element 76 ,

The sealing element 76 is at the front end of the tubular wall 73 attached. The sealing element 76 is made of elastic material, for example rubber or elastomer. The sealing element 76 is shaped disc-like and has a central portion in which a through hole is formed. The through hole passes through the central portion of the sealing element 76 in the front-to-back direction 51 and 52 and provides a tubular inner peripheral surface that defines the ink supply port 71 Are defined. The ink supply port 71 has a diameter that is slightly smaller than an outer diameter of the ink needle 102 , The cap 79 is from the outside on the tubular wall 73 set, wherein the sealing element 76 at the front end of the tubular wall 73 is attached, so that the sealing element 76 in fluid-tight contact with the front end of the tubular wall 73 stands.

If the ink cartridge 30 in a state in which the valve 77 the ink supply port 110 closes in the cartridge mounting portion 110 is introduced, the ink needle enters 102 into the ink supply port 71 one. An outer circumferential surface of the ink needle 102 Comes with the inner peripheral surface, which is the ink supply port 71 defined, thereby creating a liquid-tight seal, while the sealing element 76 is elastically deformed. When there is a front section of the ink needle 102 over the sealing element 76 moved out and into the interior of the tubular wall 73 enters, comes the ink needle 102 in contact with the valve 77 , If the ink cartridge 30 further into the cartridge mounting section 110 is introduced, moves the ink needle 102 the valve 77 against a biasing force of the spiral part 78 backwards, eliminating the ink supply port 71 is opened. Thus, the ink that is in the ink chamber 36 is stored over the interior of the tubular wall 73 in the top section of the ink needle 102 flow. Although not shown in the drawings, ink flows out of the interior of the tubular wall 73 through through holes in the tip section of the ink needle 102 are formed, in the interior of the ink needle 102 , Thus, the ink that is in the ink chamber 36 is stored through the interior of the tubular wall 73 and through the ink needle 102 from the ink chamber 30 flow out.

The ink supply section 34 does not have to with the valve 77 for closing the ink supply port 71 be provided. Instead, the ink supply port 71 be closed for example with a foil. In this case, the ink needle 102 pierce the film while the ink cartridge 30 in the cartridge mounting section 110 is introduced, whereby the tip section of the ink needle 102 through the ink supply port 71 through into the interior of the tubular wall 73 can occur. As another alternative, the ink supply port 71 with an elastic force of the sealing element 76 be closed yourself. In this case, the ink supply port could 71 from the ink needle 102 only be pushed and enlarged when the ink needle into the ink supply port 71 is introduced.

<Remaining amount detecting section 58 >

The residual amount detecting section 58 is designed so that it has a state of light coming from outside the ink cartridge 30 (ie from the residual quantity sensor 103 the cartridge mounting section 110 ) is emitted, depending on the States of the ink cartridge 30 (ie one in the ink cartridge 30 remaining amount of ink) changes.

As in 6 is shown, the residual amount detecting section 58 the housing 62 and a sensor arm 59 on.

The housing 62 protrudes from the upper wall of the inner frame 35 upwards. The housing 62 is through the through hole 98 that in the front cover 32 is formed exposed to the outside, so that the housing 62 in relation to the upper wall 141 the front cover 32 protrudes upward. In the case 62 is an interior defined with the ink chamber 36 communicates. The housing 62 can light in the right-left direction 55 and 56 let through. That is, the case 62 has translucency properties.

The sensor arm 59 is in the ink chamber 36 of the inner frame 35 arranged. The sensor arm 59 becomes of a turning shaft 61 that is in the right-left direction 55 and 56 extends, stored. The sensor arm 59 is about the turning shaft 61 pivotable. The sensor arm 59 has a swimmer 63 and the second light-blocking plate 66 on.

The swimmer 63 has a specific gravity smaller than that of the ink in the ink chamber 36 is stored. Thus, in the ink chamber 36 a buoyancy on the float 63 generated as long as the float 63 in the ink. In other words, in a state where the ink chamber 36 almost completely filled with the ink, due to the buoyancy of the float 63 is generated, such a pressure on the sensor arm 59 exercised that he counterclockwise in 6 is pivoted. The following is assumed to be the ink chamber 36 filled with ink, and it is believed that the sensor arm 59 occupy a position that is in 6 from a solid line 6 is specified.

The second light-blocking plate 66 is plate-shaped. The second light-blocking plate 66 is in the case 62 of the inner frame 35 arranged. More precisely, the second light-blocking plate lies 66 in relation to the upper wall 141 the front cover 32 higher. There on the sensor arm 59 such a pressure is exerted that he counterclockwise in 6 is pivoted, stands the second light-blocking plate 66 with a wall in contact, which is a front end of the housing 62 Are defined. Because of this contact, the sensor arm 59 held in position by the in 6 is indicated by the solid line shown. In this state, in 6 is shown blocks the second light-blocking plate 66 the light from the residual quantity sensor 103 in the right-left direction 55 and 56 through the housing 62 travels. The position of the second light-blocking plate 66 at this time is referred to as the detection position (indicated by the solid line in FIG 6 ).

More precisely, if the light from the light emitting portion of the residual amount sensor 103 is emitted on the second light-blocking plate 66 before arriving at the light-receiving section, the intensity of the light arriving at the light-receiving section is less than a predetermined intensity, for example, zero. Note that the second light-blocking plate 66 the light that is in the right-left direction 55 and 56 can completely block, which can partially attenuate light, which can break light to change its travel direction, or can completely reflect the light.

When the amount of ink in the ink chamber 36 decreases and a liquid surface of the ink is lower than the position of the float 63 from the solid line in 6 is specified (the position of the float 63 when the sensor arm 59 occupies the position in which the second light-blocking plate 66 the light is blocked by the housing 62 goes), the swimmer starts 63 to move downwards, following the sinking liquid surface of the ink. According to the downward movement of the float 63 becomes the sensor arm 59 clockwise in 6 pivoted, whereby a part of the second light-blocking plate 66 inside the case 62 is moved out of an optical path formed by the light from the light-receiving portion to the light-receiving portion of the residual amount sensor 103 travels. Thus, the intensity of the light is that at the light-receiving portion of the residual amount sensor 103 is received, the predetermined intensity equal to or greater than this. The position of the second light-blocking plate 66 (the position in 6 is indicated by a dotted line) at this time is a non-detection position different from the detection position.

<Mounting / removing the ink cartridge 30 with respect to the cartridge mounting section 110 >

Now, a procedure of attaching the ink cartridge 30 at the cartridge attachment section 110 described.

Before the ink cartridge 30 in the cartridge mounting section 110 is inserted, the valve closes 77 the ink supply port 71 of the sealing element 76 , as in 7 is shown. Thus, at this time, there is an ink flow from the ink chamber 36 from the ink cartridge 30 also interrupted.

As in 7 is shown, also lies before the attachment of the ink cartridge 30 at the cartridge attachment section 110 nothing between the light-emitting portion and the light-receiving portion of the residual amount sensor 103 , The residual quantity sensor 103 therefore, outputs a high level signal to the controller of the printer 10 out. Likewise, the attachment sensor gives 113 a high level signal to the controller of the printer 10 because there is nothing between the light-emitting portion and the light-receiving portion of the mounting sensor 113 lies.

As in 7 is shown in the ink cartridge 30 before attachment to the cartridge attachment section 110 the movable element 80 due to its own weight moves in the direction of the arrow 89 is specified. Thus, the movable element takes 80 the first position.

For attaching the ink cartridge 30 becomes the ink cartridge 30 through the opening 112 in the case 101 the cartridge mounting section 110 introduced as in 7 is shown. This is the ink cartridge 30 in the cartridge mounting section 110 introduced while the front wall 140 (the front surface of the front wall 140 ) is directed forward. Because the upper section 41U the back wall 41 the rear cover 31 in terms of the lower section 41L the back wall 41 Rear is positioned, that is, because the upper section 41U positioned closer to the user than the lower section 41L positioned on the user, the user can view the top section 41U push to the ink cartridge 30 forward into the cartridge mounting section 110 introduce.

As described above, the user will see through the sign that is at the top section 41U is attached, prompting the user to put pressure on the upper section 41U exercise (for example, a text such as "PUSH", a symbol such as an arrow or a drawing that represents pushing with a finger), prompting the top section 41U to push. While the ink cartridge 30 in the case 101 the cartridge mounting section 110 is introduced, a lower portion of the ink cartridge 30 that is, the lower sections of the front cover 32 and the rear cover 31 , in the corresponding lower guide groove 109 introduced in the housing 101 is trained.

Likewise the surface becomes 133 of the contact element 131 with a rear end of the bottom wall of the housing 101 contacted when the ink cartridge 30 in the case 101 the cartridge mounting section 110 is introduced. Thus, the surface becomes 133 from the bottom wall, which is part of the case 101 is pushed up. The contact element 131 is therefore contrary to the biasing force of the coil spring 132 moved, leaving it in the recess 129 is recorded. As in 7 is shown, the contact element 131 from below from the bottom wall of the housing 101 supported.

If the ink cartridge 30 starting from the state in 7 is further introduced in the forward direction, reaches the ink cartridge 30 a state in 8th is shown. As in 8th is shown, it starts the cap 79 of the ink feed section 34 in the leadership section 105 enter.

As in 8th is shown, is also the rod 125 the deepening 96 the front cover 32 turned and is through the opening 96A into the deepening 96 emotional. The rod 125 in the depression 96 occurred, comes with the other surface 84 of the movable element 80 , which occupies the first position, from the front in contact, whereby he the movable element 80 pushes back. Thus, the movable element becomes 80 in the direction of the arrow 88 is indicated, pivoted. That is, the movable element 80 is pivoted from the first position to the second position.

More precisely, the staff first touches 125 the first plane surface 161 , If the ink cartridge 30 is further introduced in the forward direction, the rod dissolves 125 from the first plane surface 161 and comes with the sloping surface 163 in touch and gets along the sloping surface 163 to the second plane surface 162 guided. If the ink cartridge 30 is further introduced in the forward direction, the rod dissolves 125 from the sloping surface 163 and comes with the second plane surface 162 in contact (the condition in 8th is shown). If the ink cartridge 30 is further introduced in the forward direction, the rod 125 from the second plane surface 162 dissolved and comes again in contact with the sloping surface 163 and gets along the sloping surface 163 to the first plane surface 161 guided. If the ink cartridge 30 still further forward, the rod becomes 125 from the sloping surface 163 loosened and touched the first plane surface 161 from below, making it the first plane surface 161 supports (the state in 9 is shown). At this time, the moving element takes 80 the second position.

Further, in the state that is in 8th is shown, the first light-blocking plate 67 between the light-emitting portion and the light-receiving portion of the residual amount sensor 103 positioned. As a result, the residual quantity sensor gives 103 a low level signal instead of the high level signal to the Control device of the printer 10 out. That is, the signal coming from the residual quantity sensor 103 is output is changed from H to L. In contrast, the attachment sensor sets 113 the output of the high level signal to the controller of the printer 10 continued.

If the ink cartridge 30 starting from the state in 8th is further introduced in the forward direction, reaches the ink cartridge 30 a state in 9 is shown. As in 9 is shown is the cap 79 of the ink feed section 34 in the leadership section 105 entered and the ink needle 102 got over the ink supply port 71 moved out, leaving the valve 77 against the biasing force of the coil spring 78 from the sealing element 76 has been separated. The ink cartridge 30 is thus with the biasing force of the coil spring 78 charged, causing the ink cartridge 30 pushed backwards.

Further, at this time, a lower surface becomes 85A of the first section above 85 facing down from a surface 170 supported, which is part of the housing 101 the cartridge mounting section 110 is, the surface being 170 is oriented upward and above the guide section 105 is positioned. Due to this contact between the lower surface 85A and the surface 170 is the ink cartridge 30 in the up-down direction 53 and 54 established. Here is the bottom surface 85A arranged so that they are the IC board 64 superimposed when the ink cartridge 30 viewed from above. That is, the bottom surface 85A has a section that is in the top-bottom direction 53 and 54 with the IC board 64 lies on a line. Alternatively, instead of the surface 170 for example, the staff 125 serve the attached ink cartridge 30 to prop up for positioning the ink cartridge 30 in the up-down direction 53 and 54 to care.

As described above, the rod pushes 125 on the moving element 80 and moves it to the second position. It supports an upper surface 125A of the staff 125 the movable element 80 (more precisely, the first plane surface 161 the other surface 84 ) from below. Further, the IC board 64 at this time until under the contacts 106 come and come from below with the contacts 106 in touch. In this way the electrodes become 65 electrically with the contacts 106 connected without the contacts 106 elastically deform upwards. That is, when the movable element 80 the second position assumes the electrodes 65 the ink cartridge 30 for the contacts 106 the cartridge mounting section 110 electrically accessible. This is the IC board 64 through the elastically deformed contacts 106 pushed down. Since the rod 125 the movable element 80 From below, the IC board can support 64 exactly in relation to the contacts 106 be positioned.

Further, in the state that is in 9 is shown, the second light-blocking plate 66 between the light-emitting portion and the light-receiving portion of the residual amount sensor 103 arranged. Therefore, the signal coming from the residual quantity sensor 103 to the controller of the printer 10 is output, held at the low level. In addition, the first light-blocking plate 67 between the light-emitting portion and the light-receiving portion of the mounting sensor 113 arranged. The signal coming from the mounting sensor 113 to the controller of the printer 10 is output is changed from the high level to the low level. Thus, the controller of the printer determines 10 that the ink cartridge 30 at the cartridge attachment section 110 has been fastened.

Further, in the state that is in 9 is shown, the engagement portion 130 vertically above the corresponding recess 91 , That is, the contact element 131 is no longer supported by the bottom wall, which is part of the housing 101 the cartridge mounting section 110 is. As in 10 is shown, the contact element 131 thus by the biasing force of the coil spring 131 moved down and in the recess 91 added. Because the ink cartridge 30 through the coil spring 78 biased backwards, comes the surface 134 of the contact element 131 with the surface 93 the deepening 91 from the front in contact. That is, the surface 134 of the contact element 131 and the surface 93 which the recess 91 defined, come together. This allows the engagement between the surface 134 and the surface 93 prevent the ink cartridge 30 due to the biasing force of the coil spring 78 moved backwards. That means the ink cartridge 30 with respect to the cartridge mounting portion 110 is fixed, causing the attachment of the ink cartridge 30 at the cartridge mounting section 110 is completed. At this time is the moving element 30 in the attachment state.

When the ink is in the attached state from the ink cartridge 30 and to the recording head 21 flows and from the recording head 21 consumes, decreases the amount of ink in the ink chamber 36 is stored off. According to the reduction in the amount of ink in the ink chamber 36 remains, becomes the part of the second light-blocking plate 66 in the case 62 was moved, moved to a position which is located away from the optical path of the light from the light-emitting portion to the light-receiving portion of the Remaining quantity sensor 103 is formed. Thus, the signal coming from the residual quantity sensor 103 is changed, changed from L to H. The controller of the printer 10 therefore determines that in the ink chamber 36 remaining ink becomes smaller.

Now, a process of removing the ink cartridge 30 , which is in the fastening state, from the cartridge mounting section 110 described.

When the user the ink cartridge 30 , which is in the fastening state, grasps and pulls on it, pushes the surface 134 of the contact element 131 of the engaging portion 130 the surface 93 the deepening 91 the cartridge mounting section 110 to the rear. Thus, the contact element moves 131 against the biasing force of the coil spring 132 by a drag from the surface 93 along the surface 93 up. As a result, the contact element becomes 131 which has moved upwards, as in 8th shown, then from the bottom wall, which is part of the housing 101 the cartridge mounting section 110 is supported. That is, the backward movement of the ink cartridge 30 is no longer disabled. The ink cartridge 30 Therefore, the user may continue to move backward while the user is holding the ink cartridge 30 pull out to the rear. The ink cartridge 30 finally gets off the cartridge attachment section 110 solved.

If the ink cartridge 30 is moved backward in the attachment state, also the first light-blocking plate 67 moved rearward so as to be out of the position between the light-emitting portion and the light-receiving portion of the mounting sensor 113 is moved away. Thus, the signal coming from the mounting sensor 113 to the controller of the printer 10 is changed, changed from L to H, whereby the control means can detect that the ink cartridge 30 from the cartridge mounting section 110 has been solved.

If the ink cartridge 30 is moved backward in the attachment state, also becomes the movable element 80 so moved that it's behind the bar 125 is positioned. Since the rod 125 the movable element 80 no longer supports, becomes the moving element 80 pivoted in the direction of the arrow by his own weight 89 is specified as in 7 is shown. That is, the movable element 80 is pivoted from the second position to the first position.

<Functional and Technical Advantages of the Embodiment>

According to the embodiment described above, the IC board 64 on the moving element 80 fixed, that between the first position and the second position about the axis 82 is pivoted. Therefore, the IC board 64 together with the moving element 80 movable. When the movable element 80 the second position occupies the electrodes 65 for the cartridge mounting section 110 accessible. In the state in which the movable element 80 assumes the first position, which differs from the second position, may be the adhesion of dust, ink or abrasion on the IC board 64 be prevented.

When the movable element 80 the first position is the IC board 64 under and behind the axle 82 positioned. Compared to a configuration where the IC board 64 in front of the axle 82 can be positioned to prevent ink coming out of the front surface 140 positioned ink supply section 34 flows, on the IC board 64 liable.

When the movable element 80 the first position is the IC board 64 under the upper walls 141 and 39 positioned. Thus, the IC board can be prevented from being accidentally touched by the user.

In addition, a destruction of the movable element 80 and the IC board can be prevented even if the ink cartridge 30 falls to the ground.

If the rod 125 against the movable element 80 pushes, the staff becomes 125 from the sloping surface 163 of the movable element 80 guided. Therefore, the movable element 80 be pivoted freely. When the movable element 80 takes the second position, the movable element 80 from the staff 125 on its first flat surface 161 supported. Therefore, the movable element 80 be kept stable in the second position.

During the introduction of the ink cartridge 30 in the cartridge mounting section 110 becomes the moving element 80 due to a contact between the movable element 80 and the staff 125 pivoted from the first position to the second position.

The ink supply section 34 is on the front surface 140 the front cover 32 positioned. Thus, it is possible to prevent ink coming out of the ink supply section 34 flows, on the IC board 64 liable.

When the movable element 80 the first position occupy are the electrodes 65 the IC board 64 essentially aligned to the rear. This design allows the attachment of dust, ink or abrasion to the IC board 64 be prevented.

<Variations and Variations>

In the embodiment described above, the movable member is 80 in the recess 96 arranged. However, the movable element can 80 be arranged at a different position. For example, a convex portion may be formed to be from the top wall 141 protrudes upward, and the movable element 80 can be stored at the convex portion so that it is positioned higher than the top wall 141 ,

In the embodiment described above, the rod touches 125 the cartridge mounting section 110 the movable element 80 and puts a pressure on it to the moving element 80 to pivot. However, other structures can be used to make the movable element 80 to pivot. For example, a protruding portion may be provided so as to be from the upper wall of the housing 101 protrudes downwards. The protruding section touches the movable element 80 from its front, while the ink cartridge 30 at the cartridge attachment section 110 is attached, whereupon the movable element 80 is pivoted.

In the embodiment described above, the electrodes are 65 an example of the access offering part. The electrodes 65 are on the IC board 64 arranged, and the IC board 64 is at the moving element 80 fixed so that they move together with the moving element 80 emotional. However, the accessing part is not on the electrodes 65 limited. Instead of the electrodes 65 which the contacts 106 the cartridge mounting section 110 directly touching, the accessing part may be an element providing optical access and the components in the cartridge mounting section 110 not touched directly. In this case, the element providing optical access, as an example of an accessing part, is fixed to the movable member so as to be integral with the movable member 80 emotional. For example, the first light-blocking plate 67 , which is designed to block the light coming from the fixing pin 113 is an example of an access offering part. That is, the first light-blocking plate 67 does not have to be on the top wall 141 be provided, but can be on the moving element 80 be fixed so that the first light-blocking plate 67 together with the moving element 80 is movable. The first light-blocking plate 67 moving on the moving element 80 is fixed, is also an example of a light-blocking plate.

In the embodiment described above, the first light-blocking plate 67 designed to block the light from the fixing pin 113 is emitted. That is, the first light-blocking plate 67 For the purpose of detection, whether or not the ink cartridge 30 is attached to the cartridge mounting section 110 has been attached, provided. However, the first light-blocking plate 67 be provided for a different purpose. For example, the first light-blocking plate 67 to detect a type of ink cartridge 30 At the cartridge mounting section 110 is attached (for example, a color of a stored ink) may be provided. That is, the first light-blocking plate 67 can be used as a type detection rib to detect the type of ink cartridge 30 be used. In this case, the first light-blocking plate is 67 designed to block light emitted by a type detection sensor. The type detection rib can be on the moving element 80 be fixed and can together with the moving element 80 be movable. In this case, the type detection rib is an example of the accessing part.

In such a modification, in which a component other than the electrodes 65 (For example, the first light-blocking plate 67 ) on the moving element 80 as an example of accessing part is fixed, are the IC board 64 and the electrodes 65 not on the moving element 80 fixed. The electrodes 65 and the IC board 64 For example, on the top wall 141 the front cover 32 be stored.

More specifically, in the modification in which the first light-blocking plate 67 an example of access to the moving element 80 is fixed, the first light-blocking plate 67 at such a position on the movable element 80 provided that the first light-blocking plate 67 behind and above the IC board 64 is arranged when the movable element 80 takes the second position.

In the embodiment described above, in the ink cartridge 30 before attachment to the cartridge attachment section 110 the movable element 80 held in first position due to his own weight. Further, the movable element becomes 80 pivoted in the direction of his own weight by the in 7 indicated arrow is indicated when the ink cartridge 30 in the mounting state of the cartridge mounting section 110 is solved. however can the moving element 80 be pivoted to the first position due to a force other than the weight. For example, the movable element 80 be biased by a biasing element, such as a coil spring, in the first position, whereby it moves to the first position.

Further, instead of the plate-shaped rigid IC board 64 the embodiment, a flexible substrate, which is formed of a flexible plastic film can be used.

Further, in the embodiment described above, the coil spring is used 78 of the ink feed section 34 to that on the cartridge attachment section 110 attached ink cartridge 30 to push backwards. However, a structure other than the illustrated configuration may be used to seal the ink cartridge 30 At the cartridge mounting section 110 is fixed to push backwards.

For example, a spring can attach to the ink cartridge 30 to push to the rear, at a position other than the ink supply section 34 be provided. For example, such a spring in the saving 96 the front cover 32 to be ordered. In this case, the spring will be during the insertion of the ink cartridge 30 in the cartridge attachment 110 in pressure contact with the rod 125 the cartridge mounting section 110 brought, causing the ink cartridge 30 pushed backwards.

Although ink is used as an example of the printing liquid in the illustrated embodiment, the printing liquid of the present invention is not limited to ink. For example, a pre-treatment liquid that is sprayed onto leaves before an ink during a printing operation may be stored in the printing-fluid cartridge. Alternatively, cleaning water may be used to clean the recording head 21 stored in the pressure fluid cartridge.
