DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing unit (ink tank, head tank or print unit supply system for providing heads) corresponding to a printing function of a printer which is newly improved in a printer market environment.

More particularly, the present invention relates to an ink jet printer in which an ink jet printing member such as an ink tank, an ink jet head, or an ink jet head integrated with an ink tank, which is used for ink jet, is mounted on a movable carriage. Further, the present invention also provides an invention in which a practically effective configuration for exchanging or detaching an ink jet print member is added.

[0003]

2. Description of the Related Art In a typical ink jet printer system as a printer supply system, a replaceable or detachable ink jet printing member such as an ink tank, an ink jet head or an ink jet head integrated with an ink tank, which is used for ink jet, is movable. The mainstream is an inkjet printer mounted on a carriage.

Many ink jet printers are provided with various functions according to demand, and according to the functions provided in the ink jet printer, the amount of stored ink, the type of ink, and the ink are controlled. The configuration of the discharge port for discharging is different.

[0005] Conventionally, there is a form in which an ink tank integrated head as a plurality of ink jet printing members is replaceable for one ink jet printer. In this case, by selecting an ink jet printing member to be used according to the recording mode, it can be used economically. For example, when monochrome printing is performed using an ink jet printing member for color printing, erroneous printing or only ink for monochrome printing is consumed, which is very uneconomical. When performing monochrome recording, it is possible to perform recording efficiently if an ink jet printing member that contains only monochrome recording ink is used, and erroneous mounting causes inefficiency in work.

Conventionally, this erroneous mounting is performed by electrical discrimination of the mounted printing member, so that it takes time for the user to know the erroneous mounting, which is inconvenient in operation.

Conventionally, the mounting state is controlled by providing an additional structure. For example, both the color ink tank and the monochrome ink tank have a common mounting structure. Some of them are mounted on the carriage, but in addition to this common structure, the ink tank is further provided with a protrusion, and a relief for accommodating the protrusion on a specific mounting portion of the carriage on which the ink tank is mounted is provided. And so on.

[0008]

In the case described above, a new type of ink jet printing member for color printing can of course be used in a model with added functions, for example, in a case of performing color printing. It is required that the ink jet print member for monochrome recording can be used, and it may be necessary that any of the new and old ink jet print members can be mounted. Conversely, for the conventional model, it is not only unnecessary to use a new ink jet printing member, but also it is not possible to use the ink jet printing member (for example, as described above, the ink jet printer for monochrome recording is used for the ink jet printer for color recording). In some cases, the printing member cannot be used), and in order to prevent the user from being confused, it is required that a new ink-jet printing member cannot be mounted.

Regarding the ink jet print member, there is a problem that the mounting is the main factor. When multiple ink jet print members are installed on a specific model, a unique design can be performed for each model. However, there is a problem that the manufacturing cost is increased because of the complicated structure.

[0010] Further, even if the cost is reduced by using a common ink jet printing member, an additional protruding portion is provided in order to ensure the discrimination.
In addition, there is a problem that the production cost is increased by providing the relief for accommodating the projection.

An object of the present invention has been made from various viewpoints regarding the mountability of the members constituting the above-described ink jet printer, and the replacement and mounting operations can be reliably performed. It is an object of the present invention to provide a print unit supply system which can be effectively used with a simple configuration change, an ink jet print member used in the print unit supply system, and an ink jet printer using these.

Another object of the present invention is to provide a print unit supply system and an ink jet print member used therein, which can simultaneously confirm the type of the mounted ink jet recording member together with the mounting operation.
An object of the present invention is to provide an ink jet printer using them.

Another object of the present invention is to reduce the reliability of the mechanism due to an increase in the frequency of replacement of print members,
An object of the present invention is to provide an ink jet print member in which the durability and reliability of a printer supply system are further improved, and an ink jet printer using the same, in addition to the above-mentioned objects, since the play may be large.

Embodiments of the present invention will be described below with reference to the drawings.

First, a schematic configuration of a printer according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing the overall configuration of the printer 1, FIG. 2 is a front view of the printer 1, and FIG.

The printer 1 having the automatic feeding device includes a paper feed unit 2, a paper feed unit 3, a paper discharge unit 4, a carriage unit 15, and a cleaning unit 6. Therefore, these are divided into items and outlines are sequentially described.

(A) Paper Feeding Unit The paper feeding unit 2 is configured such that a pressure plate 21 on which recording paper P is loaded and a feed rotating body 22 for feeding sheet material P are mounted on a base 20. A movable side guide 23 is movably provided on the pressure plate 21 to regulate the stacking position of the recording paper P. The pressure plate 21 is rotatable about an axis connected to the base 20, and is rotated by a pressure plate spring 24.
It is biased to 2. A separation pad 25 made of a material having a large coefficient of friction, such as artificial skin, for preventing double feeding of the recording paper P is provided at a portion of the pressure plate 21 facing the feeding rotating body 22. Further, the base 20 covers a corner in one direction of the recording paper P, and a separation claw (not shown) for separating the recording paper P one by one, and a separation paper such as a thick paper for which the separation claw cannot be used. A bank portion (not shown) integrally formed with the base 20, a separation claw operates at a plain paper position, and a switching lever 28 for switching so that the separation claw does not operate at a thick paper position, and a pressure plate 21 and a feeding rotating body 22. A release cam 29 for releasing the contact is provided.

In the above configuration, in the standby state, the release cam 29 pushes the pressure plate 21 down to a predetermined position. Thereby, the contact between the pressure plate 21 and the feeding rotating body 22 is released. In this state, the driving force of the transport roller 36 is transmitted by the feed rotator 22 and the release
The release cam 29 is separated from the pressure plate 21 so that the pressure plate 21 rises, and the feeding rotator 22 comes into contact with the recording paper P. With the rotation of the feeding rotator 22, the recording paper P is picked up and fed. The paper is started, is separated one by one by a separation claw, and is sent to the paper feeding unit 3. The feed rotator 22 and the release cam 29 rotate until the recording paper P is fed into the paper feed unit 3, and again come into a standby state in which the contact between the recording sheet P and the feed rotator 22 is released, and the transport roller 36 is released. The driving force from is cut off. (B) Paper Feeding Section The paper feeding section 3 has a transport roller 36 for transporting the recording paper P and a PE sensor (not shown). A driven pinch roller 37 is provided in contact with the transport roller 36. The pinch roller 37 is held by the pinch roller guide 30,
By urging with the pinch roller spring 31, the pinch roller 37 is pressed against the conveyance roller 36 to generate a conveyance force of the recording paper P. Further, an upper guide 3 for guiding the recording paper P is provided at an entrance of the paper feeding section 3 to which the recording paper P is conveyed.
3 and a platen (not shown) are provided. The upper guide 33 is provided with a PE sensor lever (not shown) for transmitting the leading and trailing edges of the recording paper P to the PE sensor. Further, a head cartridge 7 that forms an image based on image information is provided downstream of the transport roller 36 in the recording paper transport direction.

In the above configuration, the recording paper P sent to the paper feeding section 3 is guided by the platen, the pinch roller guide 30 and the upper guide 33, and is conveyed by the transport roller 36 and the pinch roller 3
7 is sent to the roller pair. At this time, the PE sensor lever detects the leading end of the conveyed recording paper P, and thereby obtains the printing position of the recording paper P. Also, the recording paper P
Is transported on a platen by rotating a pair of rollers 36 and 37 by an LF motor (not shown).

The head cartridge 7 uses an easily replaceable ink jet recording head integrally formed with the ink tank. The recording head can apply heat to the ink by an electrothermal converter such as a heater. Then, the ink causes film boiling due to the heat, and the pressure change caused by the growth or shrinkage of bubbles due to the film boiling causes the ink to be ejected from the nozzles 70 of the recording head as shown in FIG. An image is formed on the image.

(C) Carriage section The carriage section 15 has a carriage 50 on which the head cartridge 7 is mounted. And the carriage 50
A guide shaft (not shown) for reciprocating scanning in a direction perpendicular to the conveying direction of the recording paper P;
Of the head cartridge 7 and the recording paper P
And is supported by a guide rail 82 that maintains a gap with the guide rail 82. These guide shafts and guide rails 82 are attached to the chassis 8. Also, the carriage 5
0 is driven via a timing belt 83 by a carriage motor (not shown) attached to the chassis 8. The timing belt 83 includes an idle pulley 84
Stretched and supported by. Further, the carriage 5
0 is provided with a flexible board 56 as shown in FIG. 5 for transmitting a head signal from the electric board 9 to the head cartridge 7. In the above configuration, when an image is formed on the recording sheet P, the roller pair 36, 37 conveys the recording sheet P to the line position (position in the conveying direction of the recording sheet P) where the image is formed, and the carriage 50 is moved by the carriage motor. Column position (position perpendicular to the recording paper P transport direction)
To make the head cartridge 7 face the image forming position. Thereafter, the head cartridge 7 ejects ink toward the recording paper P in response to a signal from the electric board 9 to form an image.

(D) Paper Discharge Unit The paper discharge unit 4 is provided such that the transmission roller 40 contacts the transport roller 36, and the transmission roller 40 contacts a discharge roller (not shown). Therefore, the transport rollers 36
Is transmitted to the paper discharge roller via the transmission roller 40. The spur 42 is in contact with the paper discharge roller so that the spur 42 can rotate following the paper discharge roller. With the above configuration, the recording sheet P on which an image has been formed by the carriage unit 15 is sandwiched between the nip between the discharge roller and the spur 42, conveyed, and discharged to a discharge tray (not shown) or the like. (E) Cleaning Unit The cleaning unit 6 includes a pump 60 for cleaning the head cartridge 7, a cap 61 for suppressing drying of the head cartridge 7, and the transport roller 36.
And a drive switching arm 62 for switching the driving force from the power supply to the paper feeding unit 2 and the pump 60. When the drive switching arm 62 is not used for paper feeding and cleaning, a planetary gear (not shown) that rotates around the axis of the transport roller 36 is fixed at a predetermined position.
No driving force is transmitted to the motor. When the drive switch arm 62 is moved in the direction of the arrow A by the movement of the carriage 50, the planetary gears become free, so that the planetary gears move in accordance with the forward and reverse rotations of the transport rollers 36, and the transport rollers 36 When rotated, the driving force is transmitted to the sheet feeding unit 2, and when reversed, the driving force is transmitted to the pump 60.

Here, the positional relationship will be briefly described with reference to FIGS.

FIG. 4 is a front view of the ink jet printer, in which a front cover 105 serving as an opening / closing member is in a closed state for covering the printer. An exterior operation area is formed by LED lamps 103 and 104, each of which is provided with a reset key 102 for resetting the inkjet print member. Reference numeral 112 denotes a drawer-type tray for receiving a recorded recording medium. A configuration that can be further confirmed in FIG. 4 is a discharge unit that includes a discharge roller that is a discharge area of the recording medium. FIG. 2 to be compared with FIG. 4 shows a state in which the front cover 105 is in an open state. (This is an area where the carriage is covered with the shielding member 106 and the ink jet print member is substantially prevented from being taken out of the carriage.) To an exchange area where the ink jet print member can be attached to and detached from the carriage. The operation key 100 (second pressing portion) for moving the carriage is released. The operation keys 100 are moss green bright colors different from the gray and white peripheral portions, and are larger than the operation keys 101 and 102. The operation key 100 is located above the range of movement of the carriage, and is about 50 mm from the end of the carriage 15 in the exchange area in the drawing (30 mm from the exchange area in the carriage movement direction).
Any position that is more than a distance away may be used. ) Improved operability at a remote location.

In summary, the configuration is as follows: a scanning carriage which carries an inkjet printing member and moves;
Moving means for moving the carriage from at least an end area of the moving area of the carriage to a replacement area where the inkjet printing member can be attached to and detached from the carriage, and an opening / closing member for opening and closing the replacement area at least In the inkjet printer, the moving means is manually operated only when the opening / closing member is in an open state by an operation key provided in a position where the opening / closing member is stored in the printer in a closed state and can be operated in an open state. An ink jet printer characterized in that: According to this configuration, the carriage is not unnecessarily moved to the replacement area, and it is possible to assume that the opening / closing cover is opened when performing replacement or detachment.
Operability can be further improved.

Next, referring to FIG. 3, FIG. 5 to FIG. 8, the operation keys 100 are different from the operation keys 101 and 102 which are always exposed to the outside.
The levers (121, 110), which are operated in directions different from those of the arrow 102 (arrows 115, 120) and are displaced by the operation of the key 100 and the exposure keys 101, 102, respectively, are elastically deformed on the lever itself. Region (124, 11
7) and that it is provided as an integrated unit (FIG. 8A) so that the lever itself can be individually displaced.

The switching mechanism described below has three members shown in FIGS. 15 (a), (b) and (c) for performing a pressing operation of the respective switches 111A and 111B122 in the apparatus housing. is there.

FIG. 5 is a schematic cross-sectional view of the apparatus including a line perpendicular to the plane of FIG. 8A along the line AA. FIG.
The schematic diagram of the device cross section including the plane perpendicular to the paper plane including the line BB in FIG.

FIGS. 6 and 7 are schematic cross-sectional views of the apparatus including a plane perpendicular to the plane of FIG. 8A and including the line CC.

In FIG. 5, the elastic deformation area 117 of the lever 110 which is always in contact with the projection 105A of the printer body is shown.
Is the key 10 with respect to the rotation center axis 109 of the lever 110.
When the lever 1 rotates in the direction of the arrow 115 when the lever 1 rotates, the lever 110 is deformed and pushes the switch 111A or the switch 111B. Thereafter, the lever is returned to the state shown in FIG. 3 by the elastic force generated by the deformation. Switch 1
Reference numeral 11 denotes a single operation of the lever, which generates a signal and sends the signal to control means (not shown). The key 101 is rotatable around a rotation center 107A supported by a shaft 107 of the printer main body, and transmits a force to the receiving portion 108 of the lever 110 through the projection 106 as a pressing receiving portion.

In FIG. 6 and FIG. 7, the operation key 100 for replacing the ink jet print member is provided by the protrusion 1 of the printer main body.
Elastic deformation region 1 of the lever 121 which is always in contact with the lever 25
Reference numeral 24 denotes a key 100 with respect to the rotation center axis 123 of the lever.
Is pressed in the direction of the arrow 120 to deform the lever 121 and press the switch 122. Thereafter, the lever is returned to the state shown in FIG. 6 by the elastic force generated by the deformation. The switch 122 generates a signal by one operation of this lever, and sends the signal to control means (not shown). The key 100 is rotatable around a rotation center shaft 127 supported by a shaft holding portion of the printer main body.
To the receiving portion 121B of the lever 121. The receiving portion has a protrusion 121A as a pressing receiving portion also serving as a stopper, and prevents the receiving portion from coming off.

As shown in FIGS. 8 (a), 8 (b) and 8 (c), the lever configuration for each of the three switches is integrated so as to perform the same displacement. The structure is simplified to achieve the miniaturization of the device.

More specifically, the mechanism for transmitting the operation of the key 101 to the switch 110A and the mechanism for transmitting the operation of the key 102 to the switch 110B are connected by a connecting portion 128. A mechanism for transmitting the operation to the switch 122 is connected by a connecting portion 129. Since each mechanism part including each connection part is configured so that key operation is not transmitted to the next mechanism part,
There is no possibility that a single key operation is transmitted to a switch other than the corresponding switch and an erroneous operation is performed.

FIG. 9 is a flow chart using the operation keys, showing an example in which the printer is controlled in accordance with this flow without any need for explanation. What should be noted in this flowchart is that when the power is turned on, the key operated first has priority, and it is clear that the present invention is particularly effective in such a case. .

FIGS. 10 to 12 are views showing the configuration of an embodiment for explaining the identification mechanism and the guide mechanism of the ink jet print member according to the present invention.

The ink jet printing members F and G shown in FIGS. 12 (a) and 12 (b) have different ink tanks, and the ink jet printing member F has a plurality of different color ink tanks. The printing member G for ink jet printing is for monochrome printing and contains an ink tank for black only.

Even though the ink jet print members F and G have the same outer shape, the ink contained therein and the configuration of the discharge ports for discharging the ink are different. The identification numbers shown are given to the inkjet print members F and G themselves. It is a general configuration that the identification number is stored in an electric storage unit (not shown), and the identification number stored in the storage unit is read out through an electric contact.

In the above-described ink jet print members F and G, the mounting work is performed manually.
In this mounting work, it is conceivable that the ink used for printing adheres to the surface where electrical contact is made due to human error or the like. In this case, the recognition cannot be performed normally, and the above-described confirmation of the situation can be understood only by reading the identification number, and cannot be grasped at the time of mounting.

The present embodiment is intended to simplify the apparatus configuration and also to solve the above-mentioned problems while also serving as an identification mechanism and a guide mechanism for the ink jet print member. The configuration will be described below.

Slots 200A and 201A are formed in each of the ink jet print members F and G. In each of these slots, substrates 560 and 561 for receiving an electric signal from the substrate 56 are provided. In addition, each of the ink jet print members F and G
Have storage means for storing an identification number indicating their own type as described above.
The identification number is transmitted to the control unit of the recording apparatus via the 0,561 and the substrate 56, and the control unit transmits an electric signal for performing recording control according to the identification number. Thus, ejection based on the type of each of the inkjet print members F and G is performed.

FIG. 16 shows the nozzle configuration of the ink jet print member F for color recording. Yellow (Y),
A plurality of ejection nozzles for ejecting magenta (M) and cyan (C), respectively, are provided (nozzles NO, 1 to 16, 25 to 4).
0, 49-64) These nozzles are formed as non-ejection nozzles that do not eject ink.

Each ink-jet recording print member F,
As shown in FIG. 12, each G has a cutout at one vertex, and the cutouts are provided with protrusions 130A and 132A as recognition means at positions shifted from each other. .

Of the carriages D and E shown in FIGS. 10 and 11, the carriage E has a hook 132 which engages with any of the projections 130A and 132A of the ink jet print members F and G. Has a hook 130 that engages only with the projection 132A of the inkjet print member G. Thereby, the carriage D
Is configured such that only the inkjet print member D among the above-described inkjet print members F and G can be mounted thereon, and the carriage E is configured such that both the inkjet print members F and G can be mounted thereon.

Although the ink jet print member described above has a form in which the ink jet head and the ink tank are integrally included in one housing, the ink jet head and the ink tank of the ink jet print member are further operated by the operator. Will be described.

FIG. 13 shows an embodiment in which the ink jet head 601 and the ink tank 602 are separate bodies, and are used after being combined together. Here, the ink jet head 601 is provided with a member 601A corresponding to 130A or 132A in FIG. Also in this embodiment, it is possible to obtain the effect that the mounting of the head on the carriage and the identification of the head type can be performed at the same time as in the embodiment of FIG.

FIG. 14 shows a case where the ink jet head 603 and the ink tank 604 are separate bodies, and FIG.
A form in which a member 604A corresponding to A or 132A is provided in the ink tank 604 is shown. In this case, the same effect as described above can be obtained.

In the case of each of the embodiments shown in FIGS. 13 and 14, only when the combination of the ink jet head and the ink tank is constant between the ink jet head and the ink tank or between them and the ink jet recording apparatus attached thereto. If it can be used, it is necessary to provide erroneous mounting prevention means for permitting mounting only in a fixed relationship between the ink jet head and the ink tank.

FIGS. 15 (a) to 15 (f) show the engagement between the ink jet print members F and G and the hooks 130 and 132 when viewed from the directions of arrows A 'and B' in FIG. It is.

Each of the hooks 130 and 132 is configured to protrude toward a projection 132A provided on the ink jet print member G when engaged with the ink jet print member.

The hook 130, which engages only with the ink jet print member G, has a width of 6 mm that can engage only with the protrusion 132A. Therefore, as shown in FIGS. 15A and 15B, the projection 130A of the inkjet print member F can be engaged with the projection 132A of the inkjet print member G.
And the carriage D shown in FIG. 10 can mount only the inkjet print member G for monochrome recording.

Regarding the hook 132 which can be engaged with any of the ink jet print members F and G, the width of the engaging portion is closer to the protrusion 130A than the hook 130 by the width c.
It is elongated and has an L-shape as shown in FIGS. 15 (c) to (f). As a result, the hook 132 is located at a position different from that of the ink jet print member G.
Also, the carriage E shown in FIG. 11 can be mounted with any of the ink jet print member F for color recording and the ink jet print member G for monochrome recording. It has become.

In the engagement mechanism configured as described above, by setting the dimensions of the hooks described above, the hooks can be used not only as engagement means but also as positioning means. Can be accurately mounted on the carriage.

The hook 1 shown in FIGS. 15 (a) and 15 (b)
In FIG. 30, the width of the engaging portion is a, and FIG.
The hook 132 shown in (c) and (d) is shaped to extend the width c to the protrusion 130A side when engaged. In each of these cases, a certain gap is placed between the cutout side walls of the ink jet print members F and G, and the substrate 56
Since the pressing position with respect to 0 is shifted from the center by L, depending on the mounting state, the hook 132 (and the hook 130) is engaged at an angle α as shown in FIG. It cannot be attached well. Therefore, the width of the engaging portion is set as shown in FIG.
As shown in FIGS. 5 (e) and (f), d is larger than a,
By making the gap with the side wall extremely small e, the falling of the hook 132 (also the hook 130) at the time of attachment is corrected by the notched side wall as shown by the arrow A,
The maximum deflection angle can be set to an angle β sufficiently smaller than the angle α.

In the ink jet print member identification mechanism of the present embodiment, the user exchanges the ink jet print member G because the hook 130 engages only with the ink jet print member G for monochrome recording. In this case, it is possible to confirm that the mounted ink jet print member is the ink jet print member G for monochrome recording while confirming the mounting. Since such an identification mechanism is performed in parallel with the conventional identification using an electrical contact, it is possible to more surely check the mounted inkjet print member.

The hook 132 has been described as having a structure capable of engaging with both the ink jet print member F for color recording and the ink jet print member G for monochrome recording. This is because it is assumed that the recording apparatus is used only for monochrome recording. In the case of an ink jet recording apparatus that performs only color recording without performing monochrome recording, a mechanism in which the projection engaging portion 132A of the inkjet print member G for monochrome recording is provided is omitted. By doing so, it is possible to engage only with the ink jet print member F for color recording, and in this case, as in the above case, when the user replaces the ink jet print member F, Can confirm that the mounted inkjet print member is the inkjet print member F for monochrome recording at the same time as confirming the mounting.

FIG. 17 is a diagram showing the mounting selectivity according to the above configuration.

Each of the inkjet print member 213 and the inkjet printer 210 is for monochrome recording, and each of the inkjet print member 214 and the inkjet printer 215 is for color recording. The identification number (ID) stored inside when mounted on the carriages 212 and 217 is read by the head reading means, and the type of the ink jet print member mounted is confirmed by the head recognition means 211 and 216. However, since these are provided with the protrusions and the hooks having the above-described configurations, the inkjet print member 213 can be mounted on any of the inkjet printers 212 and 215, but the inkjet print member 213 is mounted on the carriage of the inkjet printer 210. Since it is configured to be mechanically prevented from being mounted on the carriage, it is possible to confirm that it is an inappropriate inkjet print member before mounting on the carriage. It should be noted that the solid arrows in the drawing indicate that mounting is possible, and the broken arrows indicate that mounting is not possible.

In the present embodiment, an example is shown in which the state of engagement with the hook is controlled by the position where the projection is provided, and the mounted ink jet print member is checked, but the position of the projection is the same. The configuration may be such that the state of engagement with the hook is controlled by the shape of the projection and the hook, and the mounted inkjet print member is checked.

As described above, even when the identification numbers stored in the storage means provided in the ink jet printing members F and G are not read well, the ink jet printing members F and G are not read. Confirmation of which is mounted is performed simultaneously with mounting.

As the above-mentioned ink-jet head, an ink-jet type recording means (recording head) for discharging ink by using thermal energy is subjected to a semiconductor manufacturing process such as etching, vapor deposition and sputtering.
