Description

The present invention relates to the technical field of inkjet printers, and more particularly to an ink cartridge.

Inkjet printers are commonly used print printing tools. At present, laser printers are in widespread use, but due to the high cost of maintenance for laser printers, inkjet printers are installed especially in places such as homes, stores, and offices, and still occupy a very large market share. .. Ink cartridges, which are consumables for inkjet printing, are in great demand in the market.

Here, the ink cartridge often seen at present is a consumable item in which the ink cartridge 6 is detachably attached to a mounting portion (not shown) as shown in FIG. The ink cartridge 6 has a handle 61, a joint portion 62, a chip 63, an ink supply port 64, and a housing 69a. Here, the joint portion 62 is provided on the handle 61, and the handle 61 extends from the housing 69a, has elasticity, and is rotatable around the fulcrum 611. The joining portion 62 is a portion joined to the mounting portion and prevents the ink cartridge 6 from moving upward. As a result, the joint portion 62 receives the downward acting force applied by the mounting portion, and the handle 61 receives the downward acting force. With this acting force, the handle 61 has a moment to rotate downward, and the handle 61 extends from the housing 69a. Therefore, if this moment is applied to the handle 61 for a long time, the elasticity of the handle 61 becomes insufficient, or Since the ink cartridge 6 loses elasticity and cannot be held at a predetermined position, the ink cartridge 6 is not accurately positioned and cannot be identified by the mounting portion, or cannot be fixed to the mounting portion.

The present invention will be described in more detail with reference to the drawings in specific embodiments.

<Example A>
2 and 3 are schematic views showing the ink cartridge according to Embodiment 1A. As shown in FIGS. 2 and 3, the ink cartridge 2 has a substantially rectangular parallelepiped shape. As will be understood by those skilled in the art, the ink cartridge 2 may have an elliptical shape, a circular shape, or the like depending on the actual demand. In the present embodiment, the ink cartridge 2 has a substantially rectangular parallelepiped shape, and the ink cartridge 2 has six surfaces, and the first surface 2a, the second surface 2b, the third surface 2c, the fourth surface 2d, and the fifth surface 2e, respectively. And a sixth surface 2f. Here, the first surface 2a and the second surface 2b face each other, the third surface 2c and the fourth surface 2d face each other, and are substantially perpendicular to the first surface 2a, and the fifth surface 2e and the sixth surface 2f. Are opposed to each other and are substantially perpendicular to the first surface 2a and the third surface 2c.

The ink cartridge 2 includes an engaging portion 21, a locking portion 22, a chip 23, an ink supply port 24, a position regulating portion 25, an elastic member 26 (may be defined as a first elastic member) (shown in FIG. 4), a restriction. It has a part 27 (shown in FIG. 4) and a housing 29. The engaging portion 21 is provided on the fourth surface 2d, and the engaging portion 21 has the engaging portion surface 211 and can be joined to the corresponding position of the mounting portion 3, so that the ink cartridge 2 moves upward. To prevent. The tip 23 is provided on one inclined surface that is inclined between the first surface 2a and the third surface 2c, the tip 23 is fixed to the tip holder 23a, and is electrically connected to a corresponding portion of the mounting portion 3. Has a terminal 231 connected to. The chip 23, the ink amount information, the type of ink, information such as manufacturer is stored, is capable of being contact pins 33 electrically connected to the mounting portion 3 of the printer. The ink supply port 24 is a protrusion provided on the first surface 2a and can supply ink to the printer. The position restricting portion 25 has a position restricting surface 251 and can restrict the movement of the ink cartridge 2 in the left-right direction. The housing 29 has a housing cavity 292 and a housing cover 291. The housing cavity 292 has an ink cavity 293 capable of storing ink, and the housing cover 291 is welded to the housing cavity 292 , so that the ink cavity 293 can be in a sealed state.

Further, as shown in FIG. 4, the elastic member 26 may be silica gel, an elastic metal piece, a spring, or the like, and the spring is preferable in the present embodiment. The locking portion 22 includes a joint portion 221 and a restricted portion 223, and the elastic member 26 is connected to the locking portion 22 in the expansion/contraction direction of the elastic member 26. Thus, the locking portion 22 is elastic by the action of an external force. It is possible to move in the direction of expansion and contraction of the member 26. Specifically, the restricting portion 27 is provided at a position facing the restricted portion 223 in the housing 29, the moving direction of the restricted portion 223 and the locking portion 22 forms an included angle, and the locking portion 22 has the elastic member 26. The restricted portion 223 can be engaged with or separated from the restricted portion 27 by moving in the expansion/contraction direction. More specifically, the angle between the restricted portion 223 and the moving direction of the locking portion 22 may be smaller than 90 degrees, may be 90 degrees, or may be larger than 90 degrees. Can achieve the purpose of. Preferably, the restricted portion 223 is inclined toward the elastic member 26 with respect to the vertical direction (inclined to the left from the angle in FIG. 4), and thus is moved between the restricted portion 223 and the locking portion 22. It is advantageous to

As will be appreciated by those skilled in the art, in an actual application, the ink cartridge is attached to the mounting portion, the mounting portion is provided in the printer device, and is biased to a position close to the joint 221 in the printer device (not shown). A member (not shown) is provided, the biasing member is installed opposite to the joint portion 221, and the shape of the biasing member may be designed according to the shape of the joint portion 221. 221 is taken as an example, in this case, the urging member may have a concave groove or a joint hole, and the ink cartridge is fixed in the printer device by engaging them in this way. In other alternative variations, the joint 221 may further have a normal shape such as a locking shoulder, a locking hook, etc., with which the biasing member is correspondingly changed so that both are It fulfills the purpose of joining and will not be repeated here. Further, since the biasing member can be separated from the joint portion 221 by the action of an external force, the fixing of the ink cartridge and the printer device is released, the ink cartridge is taken out, and the ink cartridge is replaced. The process will be described later.

Further, the joint portion 221 is provided between the elastic member 26 and the urging member, and by pressing the second surface 2b during mounting of the ink cartridge, the joint portion 221 is formed into a groove or a joint hole of the urging member. As will be understood by those skilled in the art, the fixing of the ink cartridge and the printer device mainly depends on the connection between the joint portion 221 and the urging member. After the mounting is completed, the restricted part 223 is separated from the restricting part 27, and the restricted part 223 is located between the restricting part 27 and the biasing member.

Further, in the process of removing the ink cartridge, the user applies an external force to the urging member to move the urging member toward the elastic member 26, and further the locking portion 22 toward the elastic member 26. When the external force applied to the biasing member is removed after the restricted portion 223 enters the position of the limiting portion 27 by moving the elastic member 26 toward the limiting member 223 while moving the elastic member 26 toward the limiting member 27, the biasing member is reset by the action of the elastic force, and The stopper 22 moves toward the urging member due to the repulsive force of the elastic member 26, but the restricted portion 223 engages with the restricting portion 27 during resetting, and the locking portion 22 continues to urge the urging member. , The biasing member has completely returned to the position, and is already separated from the joint 221. At this time, the elastic force applied to the tip 23 by the contact pin of the mounting portion 3 is applied. By this, the ink cartridge 2 jumps up and is released from the restraint by the mounting portion 3, the fixation of the ink cartridge and the printer device is released, and the removal of the ink cartridge is completed. Specifically, when the restricted portion 223 engages with the restriction portion 27 in the process of removal, the repulsive force applied by the elastic member 26 received by the restricted portion 223 is larger than the acting force applied by the restriction portion 27. The stop portion 22 is engaged with the limiting portion 27 for a short time, and finally returns to the natural state. More specifically, in the state where the ink cartridge is attached, the restricted portion 223 is not engaged with the restriction portion 27, and when the ink cartridge is taken out, the restricted portion 223 is first engaged with the restriction portion 27. When the user removes the external force by fitting and separating, the biasing member returns to the original position, and the locking portion 22 is engaged with the restricted portion 27 by the restricted portion 223 in a short time. The locking portion 22 is separated from the biasing member. As will be understood by those skilled in the art, the restricted portion 223 may exceed the position of the restricting portion 27 during the process of the locking portion 22 moving toward the elastic member 26. When the external force is removed, the restricted portion 223 still reaches the position of the limiting portion 27 during resetting, and engages with the limiting portion 27 in a short time, so that the object of the present invention can be achieved in the same manner.

<Example 2A>
FIG. 5 is a sectional view of the ink cartridge according to Embodiment 2A. As shown in FIG. 5, this is a schematic diagram showing that the locking portion 22 is located at the first position (that is, the position where the first limiting portion 271 is located). FIG. 6 is a schematic diagram showing that the locking portion 22 is located at the second position (that is, the position at which the second limiting portion 272 is located). Specifically, the locking portion 22 has a joining portion 221, a connecting portion 222, and a restricted portion 223. The elastic member 26 may be silica gel, an elastic metal piece, a spring, or the like, and a spring is preferable in this embodiment. The limiting portion 27 has a first limiting portion 271 and a second limiting portion 272, and the first limiting portion 271 is located between the second limiting portion and the biasing member. In this embodiment, the limiting portion 27 is a groove provided in the housing 29. The connecting portion 222 contacts the elastic member 26, the connecting portion 222 contacts the joining portion 221, and the restricted portion 223 contacts the connecting portion 222. As will be appreciated by those skilled in the art, the locking portion 22 may not be provided with the connecting portion 222. As shown in FIG. 5, when the restricted portion 223 is restricted by the first restricted portion 271, the locking portion 22 (restricted portion 223) is located at the first position. At this time, the elastic force exerted by the elastic member 26 on the locking portion 22 is equal to or less than the acting force exerted on the restricted portion 223 by the first limiting portion 271. It is possible for the locking portion 22 to be held in the first position without being separated from the first limiting portion 271 by the action of force. As shown in FIG. 6, when the restricted portion 223 is restricted by the second restricted portion 272, the locking portion 22 (restricted portion 223) is located at the second position. At this time, the elastic force applied by the elastic member 26 to the locking portion 22 is larger than the acting force applied by the second limiting portion 272 received by the limited portion 223, so that the limited portion 223 of the locking portion 22 is in the second position. When the locking portion 22 is located in the position, the locking portion 22 can be held in the second position for only a short time, and finally the elastic force of the elastic member 26 causes the locking portion 22 (the restricted portion 223) to move to the first position. Return to. As will be understood by those skilled in the art, the number of the restricted portions 223 may be one, or a plurality of the restricted portions 223 may be arranged along the circumferential portion of the connecting portion 222 of the locking portion 22.

Specifically, the magnitude of the elastic force of the elastic member 26 can be changed by designing the material and the shape. For example, the elastic member 26 is a metal spiral spring, and the metal material itself is an influencing element. Shear elastic modulus, the wire diameter of the spring, the medium diameter of the spring, and the number of effective windings . Further, when the elastic member 26 is silica gel, the elastic force is mainly determined by the elastic coefficient of the silica gel material itself. More specifically, the acting force of the restricted portion 223 and the first restricting portion 271 is changed by changing the material types of both and controlling the engagement depth between the restricted portion 223 and the first restricting portion 271. Change. For example, if the distance that the restricted portion 223 enters the first limiting portion 271 becomes long, the acting force of the limiting portion 223 and the first limiting portion 271 becomes large, and conversely, the limiting portion 223 and the first limiting portion 271 become The acting force becomes smaller. Correspondingly, the acting forces of the restricted part 223 and the second restricting part 272 can also be changed in a similar manner. A person skilled in the art can make changes on this basis and will not be repeated here.

7 and 8 are schematic diagrams showing a locking portion according to the second embodiment. The locking portion 22 may be provided with a reinforcing portion in order to ensure that the locking portion 22 is stably fixed at the first position and balances with the elastic force applied by the elastic member 26. As shown in FIGS. 7 and 8, in this embodiment, the locking portion 22 is provided with a first reinforcing portion 224 and a second reinforcing portion 225. As will be appreciated by those skilled in the art, there may be one, two or more reinforcements, provided that the force exerted by the locking portion 22 in the first position is balanced. First reinforcement part 224, the housing portion connected to the second reinforcing portion 225, the first reinforcement part 224, by a groove matching the second reinforcing portion 225 is provided, in the removal of the ink cartridge 2 It is possible to move the reinforcement into the groove. As will be appreciated by those skilled in the art, the reinforcement may be omitted if it can be ensured that the force received by the locking portion 22 is balanced.

FIG. 9 is a local schematic diagram showing that the ink cartridge according to Embodiment 2A is attached to the mounting portion. As shown in FIG. 9, it is not necessary to separately provide a biasing member in the printer device, the movable lever 31 of the mounting portion 3 is used as a biasing member, and the first limiting portion 271 and the second limiting portion 272 are provided. It is located between the biasing member (ie, the lever 31). The distance from the first limiting portion 271 to the elastic member 26 is larger than the distance from the second limiting portion 272 to the elastic member 26, and the distance from the first limiting portion 271 to the lever 31 is from the second limiting portion 272 to the lever 31. Is less than the distance to. When the restricted portion 223 is located at the second position, the elastic force that the elastic member 26 applies to the locking portion 22 causes the elastic member 26 to move when the restricted portion 223 is located at the first position. Greater than the elastic force applied to. As shown in FIG. 10, the schematic view of the lever 31 has a lever 31 having rotating shafts 313 and 314, a joint hole 311, and a pushing portion 312. The lever 31 is rotatable around rotation shafts 313 and 314. With the ink cartridge 2 attached to the mounting portion 3, the elastic member 26 (preferably a spring) has a horizontal axis direction. When the ink cartridge 2 is attached to the mounting portion 3, the joint portion 221 is coupled to the joint hole 311 of the lever 31, thereby limiting the upward movement of the ink cartridge 2. While taking out the ink cartridge 2, the user first pushes the pushing portion 312 of the lever 31, the pushing portion 312 moves the locking portion 22 toward the elastic member 26, and the restricted portion of the locking portion 22. 223 reaches from the 1st restriction part 271 to the 2nd restriction part 272, ie, the locking part 22 reaches from a 1st position to a 2nd position. Then, the user releases the pushing portion 312 of the lever 31, the pushing force applied to the pushing portion 312 is removed, the lever 31 immediately returns to the original position, and the restricted portion 223 is shortly moved by the second limiting portion 272. By the action of being restricted by (i.e., the restricted portion 223 is engaged with the second limiting portion 272 in a short time), the locking portion 22 can stay in the second position in a short time, and at the same time, the contact pin The ink cartridge 2 bounces upward due to the elastic force of 33 applied to the tip 23, and is released from the restraint by the mounting portion 3. Finally, the user can take out the ink cartridge 2 from the mounting portion 3.

As those skilled in the art will appreciate, the locking portion 22 shown in FIGS. 7 and 8 and the lever 31 shown in FIG. 10 are likewise applicable to embodiment 1A and will not be repeated here. Specifically, in Example 2A, the limited portion 223 is limited to the first position of the first limiting portion 271 by the limiting portion 27 in a state where the ink cartridge 2 is not attached to the attaching portion 3. As can be seen from Embodiment 1A and Embodiment 2A described above, the solution means according to the present invention abandons the fixing method of positioning the ink cartridge with the handle in the background art, and the position fixing of the ink cartridge is not accurate. Prevents a situation in which the ink cartridge cannot be identified in the mounting portion or a state in which the ink cartridge cannot be fixed in the mounting portion.

In one variation, the locking portion 22 and the housing 29 may be assembled after being integrally molded or separately molded, and if the movement of the locking portion 22 is not affected, both can satisfy the requirements of the present solution. .. In the present embodiment, as can be seen from FIGS. 5 and 9, the locking portion 22 having the joint portion 221 and the housing 29 are members that are separated from each other, and the locking portion 22 and the housing 29 may be individually assembled after fabrication.

Specifically, with the first restricted portion 423 limited to the first restricted portion 471, the locking portion 42 is located at the first position, and at this time, the elastic member 46 is applied to the locking portion 42. The elastic force exerted is equal to or less than the acting force applied by the first restricting portion 471 received by the first restricted portion 423, that is, the first position is a position where the force received by the locking portion 42 is in equilibrium. In the state where the second restricted portion 426 is restricted by the second restricted portion 472, the locking portion 42 is located at the second position, and at this time, the elastic force of the elastic member 46 is equal to that of the second restricted portion 472. The force exerted on the second restricted portion 426 is larger than the force exerted on the second restricted portion 426, that is, the elastic force exerted by the elastic member 46 on the locking portion 42 is higher than the force exerted by the second restricted portion 472 on the second restricted portion 426. That is, the locking portion 42 is in an unbalanced state, and in the unbalanced state, the second limiting portion 472 is temporarily limited to the second limited portion 426, and the locking portion 42 is temporarily in the second position. Although it can be positioned, the locking portion 42 finally returns to the first position (that is, the position of the first limiting portion 471 ) by the action of the elastic force of the elastic member 46.

FIG. 16 is a schematic view showing the ink cartridge 7 according to Embodiment 5A of the invention. The ink cartridge 7 includes a first surface 7a and a second surface 7b that face each other, and a third surface 7c and a fourth surface 7d that face each other. As can be seen from FIG. 16, unlike the above embodiment, the locking portion 72 of the ink cartridge 7 shown in FIG. 16 has two expansion and contraction portions 726, and other portions of the ink cartridge 7 can be understood by those skilled in the art. 2 and FIG. 3 may be referred to for the configuration and the positional relationship, and will not be repeated here. Specifically, the locking portion 72 includes a joint portion 721, a connecting portion 722 , a restricting portion 723, and a stretchable portion 726, and the two stretchable portions 726 are located on both sides of the connecting portion 722, respectively, and the second surface 7b.

Specifically, FIG. 17 shows a local schematic diagram showing that the ink cartridge 7 is attached to the mounting portion 3, and as can be seen from FIGS. 16 and 17, the mounting portion 3 has an expansion/contraction portion 726. When the ink cartridge is attached, the user presses the second surface 7b so that the ink cartridge faces the first surface 7a and the third surface 7c. After the expansion/contraction part 726 abuts the contact part 34, the contact part 34 reacts with respect to the expansion/contraction part 726 toward the fourth surface 7d or the second surface 7b and the fourth surface 7d. The force is applied, that is, the reaction force applied by the contact portion 34 is directed in the compression direction of the elastic member (not shown in FIGS. 16 and 17), and at this time, the pressing force applied to the second surface 7b by the user is removed. Since this is not done, the reaction force applied by the contact portion 34 is finally transferred to the elastic member (not shown) and the compression of the elastic member is promoted. As can be understood by those skilled in the art, compared to the above-described embodiment, in the case of this embodiment, the labor of mounting is more labor-saving.

In another variation, the abutting part that fits into the expansion/contraction part 726 may be another fixed part of the mounting part 3 due to the difference in the size of the mounting part, and the abutting part expands/contracts during mounting. It suffices to face the portion 726.

As shown in FIG. 20 , the housing 29 has a substantially cubic shape. The housing 29 may have a shape, specifically, an elliptical shape, a circular shape, or the like, depending on actual demand. More specifically, the housing 29 has six surfaces, where the first surface 2a and the second surface 2b face each other, the third surface 2c and the fourth surface 2d face each other, and the first surface It is almost perpendicular to 2a. More specifically, the housing 29 usually includes a housing cavity and a housing cover (not shown), and the housing cavity has an ink cavity capable of storing ink, and the housing cover is welded to the housing cavity. The presence of the ink cavity allows the ink cavity to be hermetically sealed.

Further, the ink cartridge has a first elastic member 41 connected to the housing 29 , the first elastic member 41 is connected to the locking portion 22 in the expansion/contraction direction, and the first elastic member 41 is made of silica gel or elastic. It may be a metal piece, a spring, or the like, and a spring is preferable in the present specific embodiment, and thus, the locking portion 22 is movable in the extension/contraction direction of the first elastic member 41. Specifically, the first elastic member 41 is provided in the horizontal direction, and the locking portion 22 can reciprocate in the horizontal direction. A specific connection method between the locking portion 22 and the first elastic member 41 will be described later.

Further, the locking portion 22, the can be joined or spaced biasing member 32 in an ink jet printer, the biasing member 32 is connected to the inkjet printer by the fourth elastic member 42, the fourth elastic The member 42 is installed to face the first elastic member 41, and the fourth elastic member 42 is located below the first elastic member 41 in the vertical direction. The fourth elastic member 42 may be a silica gel, an elastic metal piece, a spring, or the like, and a spring is preferable in the present specific embodiment. The fourth elastic member 42 may be provided in a horizontal direction, and may be horizontal. It may be inclined with respect to the direction. Specifically, the biasing member 32 is rotatable in the vertical plane toward the locking portion 22 by the action of an external force.

Further, a position where the external force acts on the biasing member 32 in the vertical direction (hereinafter, referred to as “first position 321”) is substantially flush with the position of the locking portion 22, that is, the first position. The first position 321 with respect to the first surface 2a is substantially the same as the height of the locking portion 22 to the first surface 2a, and at this time, the locking portion 22 compresses the first elastic member 41. The biasing member 32 presses the locking portion 22 so as to move in the direction, and correspondingly the position where the biasing member 32 is connected to the fourth elastic member 42 (hereinafter, referred to as “second Position 322”) moves in the compression direction of the fourth elastic member 42, and at the same time, since the first elastic member 41 and the fourth elastic member 42 are installed facing each other, the moving direction of the first position 321. Is opposite to the moving direction of the second position 322. Specifically, as shown in FIG. 20 , the first position 321 is located at the top of the biasing member 32, and the second position 322 is located at the bottom of the biasing member 32, that is, The first position 321 and the second position 322 are located on both sides of the rotation axis (not shown) of the biasing member 32 in the vertical direction, so that the moving direction of the first position 321 is the same as the moving direction of the second position 322. Is the opposite. More specifically, when an external force acts on the first position 321, the first position 321 separates from the locking portion 22 after the external force is removed while the biasing member 32 stops rotating. Moving toward the direction, the locking portion 22 is reset by the action of the first elastic member 41, the biasing member 32 is reset by the action of the fourth elastic member 42, and the locking is performed. The moving direction of the portion 22 at the time of resetting is the same as the rotating direction of the biasing member 32 at the time of resetting.

In one specific embodiment, as shown in FIG. 21 , the inkjet printer includes a mounting portion 3, and the biasing member 32 is a rotatable lever provided on the mounting portion 3, The fourth elastic member 42 is provided on the mounting portion 3, and the biasing member 32 is connected to the mounting portion 3 by the fourth elastic member 42. Specifically, the ink cartridge includes a chip 23, the mounting portion 3 includes a contact pin 33 , the chip 23 (shown in FIG. 24 ) is installed to face the contact pin 33, and the locking portion 22 is When joined to the urging member 32, the tip 23 contacts the contact pin 33 , and the contact pin 33 applies an elastic force upward in the vertical direction to the tip 23 and the ink cartridge. After the locking portion 22 is separated from the urging member 32, the ink cartridge is flipped up by the action of the elastic force of the contact pin 33 . More specifically, as shown in FIG. 20 , the tip 23 is provided on one inclined surface that is inclined between the first surface 2a and the third surface 2c, and the tip 23 is fixed to the tip holder 23a. The chip 23 has storage means and terminals for storing information such as ink amount information, ink type, manufacturer, etc., and the terminals can be electrically connected to the contact pins 33 in the mounting portion 3. The ink supply port 24 is a protrusion provided on the first surface 2a and can supply ink to the inkjet printer.

One connection method of the present specific example, in FIG. 22 and FIG. 23 is a detailed view of the said first elastic member 41 locking portion 22 is shown, as can be seen in accordance with the Figure 20, the together with part of the locking portion 22 enters into the housing 29, engages in a housing 29, the locking portion 22 has a joint portion 221, extends outside the housing 29, the locking A portion of the portion 22 located inside the housing 29 forms a storage groove (not shown in the drawing), and the first elastic member 41 is provided in the storage groove, as can be understood by those skilled in the art. By adjusting the size of the storage groove, the size of the storage groove is matched with the size of the first elastic member 41. As described above, the first elastic member 41 includes the locking portion 22 and the housing 29. It does not need to be fixed, and at the same time contacts the locking portion 22 and the housing 29 . As will be understood by those skilled in the art, as shown in FIG. 21 , the biasing member 32 may have a joint hole 323 (or a concave groove), and the joint portion 221 is joined to the joint hole 323 (or the concave groove). By doing so, the locking portion 22 can be joined to the urging member, and the ink cartridge is further fixed to the mounting portion 3. In some other variations, the joint of the locking portion 22 may have a conventional shape such as a locking shoulder, a locking hook, etc., with which the biasing member 32 changes correspondingly. Therefore, they satisfy the purpose that they can be joined, and will not be repeated here.

As one type of changing connection method (not shown), the first elastic member 41 is directly fixed to the third surface 2c, the locking portion 22 is further fixedly connected to the first elastic member 41, As a concrete fixing method, there are a plurality of types, for example, they are fixed by a direct welding method, and, for example, fixing blocks are provided on the third surface 2c and the locking portion 22, respectively, and the first elastic member is provided. 41 are fixed to a fixed block, all of which belong to the prior art and will not be repeated here.

Furthermore, during installation of the ink cartridge, by pressing the second surface 2b, to move the entire ink cartridge downward until the state shown in FIG. 24, i.e., the locking portion 22, with the The tip 23 abuts on the contact pin 33 , and at the same time, the tip 23 abuts on the contact pin 33. At this time, the contact pin 33 applies an upward elastic force to the ink cartridge. The ink cartridge 221 is fixed to the inside of the mounting portion 3 because the 221 is joined to the joint hole 323 (or the groove).

Further, when it is necessary to remove the ink cartridge, as shown in FIG. 24 , at the first position 321 of the biasing member 32, the external force F applied by the operator is received, and the biasing member 32 is acted on by the external force F. 32 rotates, the first position 321 of the biasing member 32 moves in the direction of the locking portion 22, and the locking portion 22 is actuated by the biasing member 32 to compress the first elastic member 41 in the compression direction. And the second position 322 of the biasing member 32 moves in the compression direction of the fourth elastic member 42, and after the external force is removed, the locking portion 22 and the biasing member 32 are simultaneously moved. The moving direction at the time of resetting and the resetting of the locking portion 22 is the same as the moving direction at the time of resetting the first position 321, and at this time, the acceleration at the time of resetting the biasing member 32 is If it is guaranteed that the acceleration of the locking portion 22 is larger than that at the time of resetting, the first state in the process of separating the ink cartridge shown in FIG. 25 from the mounting portion during resetting of the locking portion 22 and the biasing member 32 is realized. That is, the locking portion 22 is just separated from the biasing member 32, but the contact pin 33 is not separated from the tip 23.

Further, after the ink cartridge is in the first state, it is in the second state in the process of separating the ink cartridge from the mounting portion, and the locking portion 22 is separated from the urging member 32. By the action of the elastic force of the pin 33 , it is flipped up, and as shown in FIG. 26 , the tip 23 does not crimp the contact pin 33, and the joint part 221 of the locking part 22 is the biasing member 32. , The engaging portion 22 is separated from the urging member 32 completely, and the contact pin 33 causes the entire ink cartridge to flip up, and the ink cartridge. Is removed from the mounting portion 3 and the entire removal process is completed.

Further, as can be understood by those skilled in the art, the magnitude of the elastic force of the first elastic member 41 and the fourth elastic member 42 affects the acceleration of the locking portion 22 and the biasing member 32 at the time of reset. It is given as factors affecting the elastic force, the first elastic member 41 and the fourth elastic member 42 standards, and there is a degree of compression of the first elastic member 41 and the fourth elastic member 42. For example, the first elastic member 41 and the fourth elastic member 42 are both metal spiral springs, and preferably carbon steel, stainless iron or stainless steel may be selected as the metal material. The factors that affect the force include the shear elastic modulus of the metal material itself, the wire diameter of the spring, the medium diameter of the spring, and the effective number of turns. For example, the first elastic member 41 and the fourth elastic member 42 are If is also silica gel, the elastic force is mainly determined by the elastic modulus of the silica gel material itself. Further, under the condition that the standards of the first elastic member 41 and the fourth elastic member 42 are constant, the greater the compression, the greater the elastic force.

Furthermore, the acceleration at the time of resetting of the locking portion 22 and the biasing member 32 is adjusted by combining the changing of the masses of the locking portion 22 and the biasing member 32. As can be understood by those skilled in the art, the greater the elastic force of the first elastic member 41, the smaller the mass of the locking portion 22 and the greater the acceleration at reset. The smaller the elastic force of the first elastic member 41, the larger the mass of the locking portion 22, and the smaller the acceleration at reset. Correspondingly, the principle of adjusting the acceleration when the biasing member 32 is reset is similar and will not be repeated here.

As one preferred embodiment, if the initial acceleration at the time of resetting the biasing member 32 is larger than the initial acceleration at the time of resetting the locking portion 22, it is advantageous for quick removal of the ink cartridge, that is, Even in the initial stage after the external force is removed, the biasing member 32 is already separated from the locking portion 22, and at this time, the ink cartridge is flipped up by the action of the elastic force of the contact pin 33. After that, the ink cartridge can be taken out. A plurality of specific examples will be given below. Specifically, in the following multiple examples, the wire diameter of the first elastic member 41 is 0.4 mm, and the unraveling length is 14 mm. The diameter is 4.1 mm, the number of effective windings is 8, the pitch is 1.6 mm, the wire diameter of the fourth elastic member 42 is 0.4 mm, and the unraveling length is 9 mm. Yes, the medium diameter is 2.6 mm, the number of effective windings is 9, the pitch is 1 mm, and the magnitude of the external force is 8 to 10 N. And more solutions can be realized.

In Example 1, the mass of the locking portion 22 is 0.31 g, the mass of the biasing member 32 is 0.45 g, and the first elastic member 41 is compressed by the action of an external force.

Is 8 N, the initial acceleration when the locking portion 22 is reset is 6.57 m/s ² , and the initial acceleration when the biasing member 32 is reset is 15.69 m/s ² .

In Example 3, the mass of the locking portion 22 is 0.38 g, the mass of the biasing member 32 is 0.51 g, and the first elastic member 41 is compressed by the action of an external force. Then, when the external force is removed, the elastic force applied by the first elastic member 41 to the locking portion 22 is 2.5 N, and the elastic force applied by the fourth elastic member 42 to the urging member 32. Is 10 N, the initial acceleration when the locking portion 22 is reset is 6.57 m/s ² , and the initial acceleration when the biasing member 32 is reset is 19.61 m/s ² .

In Example 4, the mass of the locking portion 22 is 0.38 g, the mass of the biasing member 32 is 0.58 g, and the first elastic member 41 is compressed by the action of an external force. Then, when the external force is removed, the elastic force applied by the first elastic member 41 to the locking portion 22 is 2.5 N, and the elastic force applied by the fourth elastic member 42 to the urging member 32. Is 8 N, the initial acceleration when the locking portion 22 is reset is 6.57 m/s ² , and the initial acceleration when the biasing member 32 is reset is 13.79 m/s ² .

In Embodiment 5, the mass of the locking portion 22 is 0.38 g, the mass of the biasing member 32 is 0.58 g, and the first elastic member 41 is compressed by the action of an external force. Then, when the external force is removed, the elastic force applied by the first elastic member 41 to the locking portion 22 is 2.5 N, and the elastic force applied by the fourth elastic member 42 to the urging member 32. Is 10 N, the initial acceleration when the locking portion 22 is reset is 6.57 m/s ² , and the initial acceleration when the biasing member 32 is reset is 17.24 m/s ² .

In Example 6, the mass of the locking portion 22 is 0.6 g, the mass of the biasing member 32 is 0.65 g, and the first elastic member 41 is compressed by the action of an external force. Then, when the external force is removed and the elastic force applied to the locking portion 22 by the first elastic member 41 is 2.4 N, the initial acceleration at the time of resetting the locking portion is 4 m/s. ² , the elastic force applied to the biasing member 32 by the fourth elastic member 42 is 6.5 N, and the initial acceleration of the biasing member 32 at the time of resetting is 10 m/s ² .

Further, as can be understood by those skilled in the art, as can be understood from the above-mentioned five embodiments, the elastic force applied to the locking portion by the first elastic member 41 is 2.4 to 3N, and the fourth elastic member 42. The elastic force applied to the urging member 32 is 6.5 to 12 N, and when the mass value of the locking portion is 0.31 to 0.6 g, the initial acceleration when the locking portion is reset is 4 to 9.6 m/s ² and the mass value of the biasing member 32 is 0.45 to 0.65 g, the initial acceleration when the biasing member 32 is reset is 10 to 26. It is 6 m/s ² . As can be seen, even if the initial acceleration at the time of resetting the locking portion has a maximum value of 9.6 m/s ² , it still has a minimum initial acceleration value of 10 m/s ² at the time of resetting the biasing member 32. Since they are smaller, the objects of the present invention can be achieved within the above numerical range. As one of ordinary skill in the art will appreciate, not all experimental data are listed here, and, as is common knowledge in the art, any of these experimental schemes are feasible and will not be repeated here. ..

In another embodiment, the engaging portion 22 has a mass of 0.4 g, the urging member 32 has a mass of 0.53 g, and the first elastic member 26 is compressed by an external force.
