Abstract

PURPOSE:To obtain profile irregularity and equalizing property with respect to a discharge opening forming surface by connecting an ink communicating member having high rigidity at a sucking body to an ink communicating member consisting of elastic member at a cap. CONSTITUTION:A tube 35d as an ink communication section at cap side has elasticity and a cylindrical section 32d as an ink communication section at cap lever side is formed by a material which can be regarded as a rigid body with respect to the elasticity of the tube 35d. Accordingly, the holding precision of a cap 35 with respect to a lever 32 in a non-capped state i.e., the profile irregularity of the cap 35 with respect to a head discharge opening forming surface can be obtained by the cap lever cylinder section 32d. The equalization of the cap 35 with respect to the head discharge opening forming surface at capping is allowed by deformation of the tube 35d. Thus, both the profile irregularity and the equalizing property with respect to the discharge opening forming surface can be obtained.

Further, the suction bow [] does not necessarily have to be inside the slit. 35e is a flange portion, which serves as a member to prevent it from coming off when attached to the gap boulder 34. The tube portion 35d is connected to the cylinder of the cap lever 32 as described above If the A-sup 35 is attached to the cap boulder 34 and then attached to the gap lever 32 in that state (t Lj is 15), the tube section 35d is connected to the ink flow path 32h of the cap lever 32. , the cap holder 34 is equalized by the holder guide part 34b, and the hook part 34a engages with the vertical locking surface 32g of the cap lever 32 to release and stop.The cap is equalized by the head discharge port forming surface. When doing so, equalization is performed smoothly because the tube portion 35d is deformed or the cap lever 32 is moved relative to the cylindrical portion 32d. It is a diagram showing the equalized state when viewed from one side and from the side. The cylindrical part 3211, which is the ink passage part on the cap lever side, is made of a material that is considered to be two rigid bodies with respect to the elasticity of the duplex part 35d.Therefore, the holding accuracy of the cap 35 relative to the L/bar 32 in the uncapped state, that is, the head The discharge port formation and the surface accuracy of the cap 35 with respect to the surface are determined by the cap lever cylindrical portion 32.
d, and equalization of the cap 35 with respect to the head discharge port forming surface during capping is allowed by deformation of the duplex portion 35d. On the other hand, if the communicating parts of both the cap and the gap lever are made of elastic parts, the number deviation will be sufficient without considering the elastic modulus of both communicating parts at +, which fully satisfies the twin knobs of retention and equalization properties. As a result, the range of material selection is narrow.
Design 1 - Disadvantageous. On the other hand, if the cap side communication part is made of a rigid body and the A-Yap lever side communication part is made of an elastic member, the gap-side communication part and the 6-Yap main body become separate members, and the cap is constructed by combining NiO 1 and others. This is disadvantageous in terms of manufacturing, and furthermore, the lever-side communication part that should protect A~Yap and apply capping force to the cap L5 has less elasticity.
Then, a problem arises in terms of holding accuracy. Furthermore, in this example, the holding accuracy and equalization performance are further improved in relation to the configurations of the gap holder 34 and the cap lever 32. Since the spherical concave portion of the holder guide portion 34b and the convex spherical guide surface 32e of the lever 32 are in contact with each other, the cap 35
When the holders 34 to 5 come into contact with the discharge forming surface,
The cab 35 is displaced along the spherical surface, and the holder 3
4 hook portion 34a and the vertical and horizontal locking surfaces 3 of the lever 32
This is because 2g and 32f function as a retainer and allow displacement along the spherical surface. When the mounting part between the boulder and the lever is simply used for the function of securing the outside of the lever, the installation may be due to the dimensional accuracy of the part or changes over time, and the surface of the gap relative to the discharge port forming surface may be affected. If the output accuracy is poor (particularly if a lubricant is applied to the above spherical contact surface in consideration of equalization), the l:f knee layer (this is severe) and the equalization will be incomplete. However, in this example, such inconvenience is not a problem. Now, referring again to Fig. 2, )+13 is a paper feed row for conveying recording media such as paper, and for example, an aluminum drawn tube is coated with elastic paint (urethane resin, etc.) on the surface.
It can be formed by applying acrylic resin, etc.). In addition, this hole 36 functions as a bracket for regulating the recording surface of the recording medium on its outer surface, and
The interior is used as a storage section for waste ink. 37 is a waste ink absorbing section installed inside the roller 36, and is made of salt and vinyl.
A tube formed thinly using a glass deck is filled with an absorbent material such as polyJ stell cotton, so that the ink can be easily absorbed in the axial direction. In addition, i

Furthermore, the fibers of the absorbent material themselves are preferably made of non-liquid absorbing material such as resin or metal.5. However, a slight drop is also good. Static electricity generated due to friction with the paper (,) Therefore, the paper feed roller (Nora 36 is charged at 1.2 and the discharge is at q) to prevent circuit elements from being destroyed.

Furthermore, seven holes 361d are formed in the PF roller gap 361 to accommodate a PF roller grounding member (P roller ground), which will be described later. This hole is formed to protrude by a predetermined amount and is open to the atmosphere to promote evaporation from the waste ink absorber 37. 362 bal)

This is provided to allow the F roller ground 362 to protrude and be fixed in the same position. 38 is fluororesin, carbon fiber a! It is handled as a paper presser made of human resources, etc., and is divided into four parts and attached to the chassis 1, as detailed in Section 30. Further, a gear 38B is fixed to one end of the shaft 38A for releasing the pressing force of the paper presser 38, and the other end engages with a bearing 38G that pivotally supports the shaft 38A. The bearing 38c is fixed to the chassis 1. The gear portion of the release lever is engaged with the gear 38B, but numeral 639 (not shown) is a paper feed motor, which is connected to the paper feed roller 36 via a speed reduction mechanism with a predetermined ratio. Reference numeral 40 indicates a recording paper such as paper 1 and soil.Next, the operation of the following configuration will be explained.First, the normal recording operation
Timing bell due to the rotation of the axis of 1) i: j through 3
- As the toss screw 2 rotates, the carrier 6 is scanned along the recording paper 40 in the printing digit direction by the lead bin 7 engaged with the lead groove 2d. Here, since the carrier motor 11 is biased by the motor spring 14, the timing belt 13 is always tensioned and good transmission is not achieved. Although a force is applied, the weight of the carrier motor 11 absorbs this inertia, so the load applied to the motor rotation gear 14 is small. ,
If an air damper or a hydraulic damper is provided in connection with this spring, the noise caused by the vibration of the rotor of the motor 11 can be reduced when the carrier 6 is started or stopped. By appropriately selecting the weight and the coefficient of the spring damper, the first spring rotor's overshoot can be reduced. Next, referring to FIG. 11) to FIG.
-: [□] The operation in record B) will be explained. FIG. 10 is a timing chart showing the operation timing of each part, and the operation timing of each part as shown can be determined by the number of pulses applied to the motor 11. FIG. 11 is a perspective view showing the detailed structure of the clutch gear 4 and the timing gear 21. When the clutch gear 4C's key groove 4d engages with the key part 2h of the lead screw 2, The clutch gear 4 slides on the lead screw 2 and rotates together t6°.Also, the clutch gear 4 is urged toward the carrier 6 by a spring 5, and normally,
During recording, it is in a predetermined position due to the groove 21 of the lead screw 2 and rotates together with the cut screw 2. When the recording head 9 moves to the Baum position, the clutch gear 4 is pushed by the carrier 6 and starts to engage with the timing gear 21. The clutch gear 4 has a star -1 tooth 4e and a normal drive tooth 4C2, and a start tooth 4e+ and a drive tooth 4e2 (formed at different positions in the width direction of the off-latch gear. The clutch gear 4 is not formed in the same manner over the entire circumference, but has a portion having a curved surface portion 4b.Furthermore, at the end of the clutch gear 4, a collar 4a is formed over the entire circumference. The timing gear 21 is shown in Fig. 7 (B)).

, at this time, the lead bin 7 is not at this position in FIG. 13(A) 1. , the blade 17 and the ink carrier 19 are located, although not shown. At this time, the clutch gear 4 rotates with the rotation of the lead screw 2, but the start teeth 4c+ and the start teeth 21b are not in a positional relationship where they engage (Fig. 13(A)).
) reference). Therefore, the timing gear 21 does not rotate, and moreover, the driving tooth 2]b2 at the left end of the timing gear 21
Since the flange 21h and the flange 21h are in a positional relationship where they can come into contact with the flange 4a of the clutch gear 4 with a small gap, the timing gear 21 cannot rotate in either direction. This prevents the timing gear 21 from rotating inadvertently even if some rotational force or artificial force is applied to it, and prevents errors in the operating position of the recovery system mechanism. can. When the recording head 9 moves toward the home position and the carrier 6 pushes the clutch gear 4, the positional relationship between the clutch gear 4 and the timing gear 21 becomes final ζ,
The result is as shown in (B). With this overculm, start tooth 4c

It rotates once, and the positional relationship if changes sequentially from FIG. 12 (A) to the δ-cross state as shown in FIG. At this time, until the star teeth 4e+ and 211)l engage, the curved surface portion 4b, which is a non-meshing portion shown in FIG. E0
Because the timing gear is located at the neck, the timing gear may move inadvertently and the other drive teeth and 5 and 2 will not engage first. Clutch gear 4 and timing gear 2

,. The rotation of the timing gear 21 is always correct (starts from S7M). With this result, the operation of the recovery system mechanism driven through the timing gear 21 is ensured. , it is not necessary to make the mounting precision of the clutch gear 4 and the timing gear 21 so high.In addition, as shown in FIG. 7(B), the timing gear 21
Of the drive teeth, the drive tooth 21b whose position is different is the drive tooth that engages when the L curved surface portion 41 comes into contact with the timing gear 21 again. That is, if these drive teeth are located on the same neck as the normal drive teeth 21b2, they will come into contact with the curved surface portion 4b, so their position will be shifted and the drive teeth L2 will be engaged. Further, while the driving teeth are engaged and the timing gear 21 is rotating at position 5, the hook 6c attached to the carrier 6 "slides" on the side surface of the timing gear 21. When the lead bin 7 leaves the groove 31) before the teeth mesh with each other, the sound recording head 9
can be prevented from leaving the Baum position. This is because the lead screw rotates twice when the recording head 9 is at the home position and performs a series of recovery processes, so the dobbin 7 may move to the groove 3c. In addition, on the upper side, a series of recovery processes are performed using the lead screw 2.
Although the rotation is performed in this embodiment, the rotation is not limited to this, and any rotation can be set, thereby increasing the degree of freedom in designing the clutch mechanism and the like. 14(A) to (D) are explanatory diagrams showing the sequential operating states of the mechanism related to the blade 17 etc., and FIG. 15(A1-(C)
1 shows the sequential operating states of the mechanism related to the cap 35, and FIGS. 16(A) and CB) show the waste ink roller 3.
13 is an explanatory diagram for explaining the operation of a mechanism for introducing waste ink into the waste ink storage section 37 in 6, and the operation will be explained with reference to these figures and FIGS. 12 and 13 described above. First, the carrier 6 moves in the Baume position direction (arrow B direction). At this time, as shown in FIG. 13(A), the lead bin 7 is engaged with the lead 28, and the ejection port 9c of the head element 9a is opposed to the ink carrier 19 (see FIG. 14(A)). In position, here,
At this position, the operator of the (+) ejection energy generating element is driven to perform ejection operation (hereinafter referred to as preliminary ejection), and the thickened ink, etc. is ejected with the ejection force. The recovery operation by ejecting this '' can be introduced. Preliminary ejection is also performed periodically to prevent unused ejection [] ink from increasing in viscosity during normal recording. Note that FIG. 14(A) is a side view of the vicinity of the same position. Furthermore, when the lead screw 2 is rotated and the carrier 6 is moved in the direction B'7j as shown in J2 shown in FIG. The start tooth 4c is in a position where it can engage with the start tooth 21b of the timing gear 21. Thereafter, the clutch gear 4 rotates in synchronization with the lead screw 2, the start teeth engage with each other, and the timing gear 21 rotates in the r] force direction as shown in FIG. 14(B). - force, the lead bin 7 is from the introduction groove 3c to the position groove 3
b, so even if the lead screw 2 rotates, the gear rear 6 does not move. When the timing gear 21 rotates in the D direction, the set lever 20 starts to move in the Ei direction because the gear part A and the gear part of the set lever 20 are in mesh with each other. Until this time, the hook portion 16e of the blade lever 16 is engaged with the claw portion of the chassis, so only the set lever 20 rotates.
The blade lever 16 is stopped, but eventually the set surface 2Of of the set lever 20 rotates in the F' force direction due to the rotation of the blade shaft 18)"+18a. When the timing gear is rotated in the 2175 direction and set in a state where it can be engaged with the discharge port surface,
The hook part 16 of the blade 17 bar 16 has come off the chassis claw! - The lever 20 and the blade lever 16 also rotate further, and the discharge port surface of the head 9 is wiped by the blade 17 as shown in FIG. 14(C). At this time, the ink liquid etc. removed by wiping the plate 17 is removed only in one direction, that is, only downward in this case, and this removed ink liquid etc. is removed from a portion of the ink carrier I9. The ink carrier 9 starts to come into contact with the ink absorber 23. When the set 1 collar 20 further rotates, the 14th ink carrier
As shown in FIG. Blade 1 from the [” forming surface
The wiping part 23a receives the dust and the like that has been wiped off by the cleaning part 7, and also absorbs the ink droplets that have adhered to the four surfaces of the 18' exit. From this 1+ and 42, the ink absorbing ability of the ink carrier j9 can be maintained for a long period of time. Further, the timing gear 21 rotates in the D direction, but the stop teeth 20a, 2i) of the set lever 20 and the stop cam 21δ of the timing gear 21 face each other and are in contact with each other.
At the same time as the rotation of the set lever 200 is restricted, the driving teeth of the timing gear 21 become toothless, so that no force for rotation is applied. As mentioned above, blades and blades have J,
Since the absorber that retains the ink liquid, etc. that is removed during preliminary ejection is the same as the ink receiver used during preliminary ejection, the apparatus can be made smaller and the time required for these recovery operations can be shortened. When the timing gear 21 rotates further, the cap cam 21e of the J timing gear 21 initially rotates as shown in FIG.
The cap 3 also restricts the rotating shaft 32a of the cap 32c as shown in FIG. 15(A).
5 is stopped at a position away from the ejection port surface of the head element 9a, and is located at 2. Next, the timing gear 21 is further
When rotated in the direction, it comes off from the cap cam 21e, so
Since the restricted state is released, the rotational lever 24f of the cylinder 24 is rotated by the spring portion 22b of the ink absorber spring 22, and the cylinder 24 is moved to the 17th position, as shown in FIG. 15(B). The cap portion 35a of the cap 35 comes into pressure contact with the discharge surface 2, and the cap operation is started.
do. Note that FIG. 13(B) does not include the ten-sided view at this time. Now, the above is the cleaning and capping operation of the nozzle surface, and normally it stops here and then repeats the operation according to the input of the next recording signal.
The operation of - is performed in reverse and the recording operation begins. Next, we will trace the suction recovery operation that is performed when it is difficult to obtain a good discharge condition even with preliminary discharge. When starting this, the timing gear 21 is further rotated from the gap position, and the cap lever 32 is pressed by the four-way cap cam 21f, so that the cap 35 is moved six inches from the discharge port forming surface as shown in FIG. 15(C). Separate them. When the timing gear 21 further rotates in the D direction, it comes off the cap cam 21f again, so the gap portion 35a
comes into pressure contact with the discharge port surface. Now, to explain the pump operation in detail, when the recovery operation 1 is entered after the sealing cap is completed, the suction operation starts. At this time, first, when the timing gear 21 is rotated, J, re-piston set cam 2] and g are attached to the piston shaft 27.
Since the piston pushing H roller 29 is pushed, the piston shaft 27 moves in the H direction as shown in FIG. 16(A). Then, the piston 28 is pushed/'I by the piston presser 27b &: and moves in the H direction, and the pump chamber 42 becomes under negative pressure. Since the ink flow path 2411 is blocked by the piston 28, the pump chamber 42
The piston 28 is in a movable state only by increasing the negative value of . On the other hand, the ink flow path 24e opens after the old cap shown in I and 5 above (see 1 in FIG. 16, 4).
Suction of the cap 35 [The ink from the pad 9 is suctioned from the cap 35b. The suctioned ink passes through an ink passage 32f formed inside the cap lever 32, passes through a communication hole in the lever seal 33, further passes through an ink passage 24e of the cylinder 24, and flows into the pump chamber 42. At this time, conventionally, ink may be left behind at the bottom of the cap 35 as shown in FIG. 24(A). In addition, the suction port is biased toward one end of the 4-Yap V.
Although it is possible that the ink may leak, when the printer is placed in a striped manner, ink remains in the hole of the suction port and becomes 1, as shown in FIG. 24(B). On the other hand, in the cap of this embodiment, - is biased toward the edge side, and "'C suction t', ', m', . . . (See Figure 8 (A))
, as shown in FIG. 24(C), the ink is collected in the slit by surface tension, and the remaining ink can be sucked out by the suction at the bottom. Therefore 1. Whether the printer is used horizontally or vertically, there is no deterioration in performance. Note that the width of the slit 35b is 0.4 to 0.7 mm, although the tensile force of the thin band ink is strong.
Good results were obtained. When the timing gear 21 further rotates, the cap 35 is moved away from the discharge port surface by the gap cam 2111 again, and the remaining negative pressure in the pump chamber causes the ink in the discharge port 31a to be sucked into these parts. Remove any remaining ink. Next, rotate the timing gear 21 in the opposite direction (Fig. 14 (1)).
When the piston reset cam 21i pulls the piston return roller 3o, the piston shaft 27 is moved in the J direction as shown in FIG. 16(B). At this point, the piston 28 moves after coming into contact with the piston holder 27e of the piston shaft 27, so a gap Δβ increases between the end surface 28b of the piston 28 and the piston retainer 27b. 27 and the piston 28, the waste ink sucked into the pump chamber 42 passes through the above-mentioned gap ΔI, passes through the groove 27f of the piston shaft,
The ink passes through the ink flow path 24e of the cylinder 24, and further passes through the waste ink pipe 24g, and is discharged near the center of the waste ink absorber 37. Note that at this time, since the ink flow path 24, e of the cylinder 24 is closed by the piston 28 at the beginning of the operation of the piston 28, waste ink will not flow back toward the cap. Note that when the pump operation is finished, the piston 28 moves further and the ink flow path 24e of the cylinder 24 is no longer blocked, but the waste ink absorber 37 is present in the communication path from the cap 35 to the atmosphere, and the inside of the cap is Since the ink is kept in a moist atmosphere, there is almost no evaporation of the ink and the old outlet or liquid path does not dry out. In addition, the ink remaining in the cylinder 24 is collected by the piston absorber 241 and then guided to the waste ink absorber 37 via the flow path absorber 242 due to surface tension. I! Ink flows backwards towards the cap! 75 will be stopped. The configuration of the backflow prevention 11 and the like is not limited to that shown in FIG. 9, but can also be configured as shown in FIGS. 25(A) to 25(C), for example. First, in the same figure (A), the piston absorber 241 is extended. In other words, it is configured to directly contact the waste ink absorber 37, that is, it is integrated with the flow path absorber 242. Next, in the same figure (B), in order to restrict the displacement of the piston absorber 241 in the axial direction, a claw 24g facing inward is provided on the end face of the cylinder 24, and when the piston absorber 241 is inserted. J: It's something that gets stuck in there and becomes an uncut Jl. In addition, similarly to the same figure (C) iJ, to prevent the piston absorber 241 from being removed, a stopper 24m made of an elastic material and having several thin claws is later inserted into the piston ring and fixed. It was designed so that it would work. FIG. 17 collectively shows the sequence of the preliminary ejection or suction 1 recovery described above. However, (57, then) the blade 17 waits in a state where it can be wiped (set state, see Fig. 14 (B)), and after wiping, the blade 17 is tilted at 2 with respect to the absorber 23 (reset state). .Figure 14 (see A+) There is a roar, and then the set lever -2
The sequence L2 shows the sequence in which grade 17 is set to a wipeable set state immediately before zero returns to its original position. Note that the recovery operation can be performed once, for example, immediately after the power is turned on next time when the power has not been turned on for three days or more.Also, the recovery operation can be performed in response to the operation of an appropriate start switch. In addition, wiping with a blade is performed just before closing the cap and immediately before printing starts, and during printing, wiping in the direction of the ejection port array (M direction) is performed once every 60 seconds. Furthermore, preliminary ejection ζ'-1 For example, (1) When 11 sources are ON, 50 shots x 64 ejections f-'l (500Hz) (2) Immediately after printing starts Ai 50 shots x 64 ejections L (500Hz) to 3 ) 15 shots x 64 discharges 1-7 (500Hz) every 12 intervals during printing

i...I'll explain next. In these figures, numeral 38 is a fluorocarbon resin, carbon material, etc., as described above, which is a paper pressing plate that presses the recording spatula 1 by applying pressing force to the recording paper being fed. 9 discharge L]Mi1 and the recording paper so that there is a predetermined distance between them.
It is held by the elastic force of D. Details of the side of this machine are shown in FIGS. 18(A) and 18(B). t6 FIG. 18(A) is a diagram in which the paper pressing plate 38 is applying a pressing force to the paper feed roller. In this case, the notch of the shaft 38A, which has a 0-shape in which a part of the circumference is linearly cut out and is slidable in the rotational direction on the paper press plate 38, is connected to the end 38 of the spring plate 38D. At this time, the end portion 38E of the paper presser plate receives a biasing force toward the "fla" in the figure by the spring plate 38D. As a result, the paper pressing plate 38 attempts to rotate clockwise around the shaft 38A, thereby applying a pressing force to the two paper feed rollers 36. 18(B) shows a state in which the pressing force exerted by the paper pressing plate 38 is released. In this case, the shaft 38A rotates 7, and the arc portion of the shaft 38A presses the end portion 38F. At this time, the spring plate 381 is pressed down as a whole toward the center of the figure. As a result, the end portion 38E receives no urging force from the spring plate 381]. In this example, when the force is released, the shaft 38A and the paper presser handle 38 have a certain amount of frictional force and are engaged with each other.

2, the paper push λ handling 38 does not change its rotational position significantly. Due to this, even when it is necessary to release the pressing force of the paper presser 38, the movement of the recording head is not hindered by handling the paper presser. Further, the paper pressing mechanism described above is a mechanism that can apply a pressing force that does not prevent the paper feed roller 36 from properly conveying the recording paper within a limited space. In other words, without using an elastic member in the paper press plate itself,
The pressing force is normally applied to the bottom chassis of the device, which is a dead space.
Since the force is generated by a leaf spring arranged along the top, the degree of freedom in setting the pressing force is increased by adjusting the length of the square spring, and the paper pressing member can be made smaller. Note that the leaf spring 380 is attached to the chassis 1 by a fixing member (not shown). Referring again to FIGS. 3(A) and CB), 6o is a paper ejecting roller for ejecting the recorded recording paper, and 61 is a paper ejecting roller H1 that pushes the recording paper being conveyed by the paper ejecting roller 60. There is a spur L7 that applies force and regulates the direction in which the recording paper is ejected to generate conveying force. 62ζJ, ↑'' 1 Paper roller 60 and paper feed roller 3 (1) This is a transmission τ roller placed between the paper roller 60 and the paper feed roller 3 (1) for transmitting the rotation of the paper feed roller 36 to the paper ejection roller 60.
The transmission of the same rotation between the two is first performed by the frictional force l caused by the contact between the two. The paper ejection roller 60 has a circular shape with different flat diameters at both ends and a middle portion, and the transmission roller 62 contacts the middle portion of the paper ejection rollers 6f' and 6l, which have smaller diameters. Therefore, both ends of the large-diameter force that transport the recording paper rotate at the same time at a circumferential speed slightly greater than the circumferential speed of the paper feed roller 36. As a result, when the paper is ejected, the recording paper is conveyed with tension (4), and the recording surface can be formed well. , coil springs each having an appropriate impact coefficient are used.The details of the mechanism will be explained in detail with reference to FIG. 19, taking the case of beat@61 as an example. In Figure 19,! -; 61A is made of an 11 yl spring, and the center of the spur 61 is ju-) t- its side numbers, and 2 extending shafts''(-; 61A is made of an 11 yl spring, and the spur 61 and t!-! 1.fl are 11
1. Engage freely. 103BC” rotating shaft 61.
It is a shaft support opening that supports both ends of A, and is formed as part 2 of the inner lid 103 shown in FIG. Shaft support material 1 +
43B supports the shaft 61A so as to be slidable in its axial direction. 103C is a regulating member 5 for regulating the movement of the spur 61 in the direction of the rolling axis 75 and in the direction perpendicular to the kneading direction.
They are provided on both sides of the spur 61. The restricting portion 14xo3c is also formed as an inner Eiio3 portion 7 similarly to the shaft support member 103B. With the above configuration, the shaft 6], A supports the spur 61, and uses its bending elastic force to generate a pressing force of the spur 61 against the paper ejection roller 60. As shown in Fig. 3 (A), a spring part +14' 103 A is attached to the rear end of the inner cover 1 [ ] 3 ζ, 2, and the reaction force of the case 101 exerts a pressing force in the direction of the paper roller B1. receive. This pushing 11-force and the elastic force of the rotating shaft 61A. ;

The engagement with G becomes reliable. This knot W, beat Φ61do 14F
The positional relationship with the paper roller 6 () is kept very constant. Alternatively, by fixing the rotation shaft 60C against the hooking part +A, etc., the accuracy of the inner lead may be affected. ) and maintain a highly accurate relationship. In the transmission roller 62 as well, the rotary shaft 62A made of a spring has the same function, and the elastic force of the shaft 62A provides a contact force to the paper feed roller 36 and the paper discharge roller 60. As described above, the paper discharge roller 60 has a shape in which the diameter of the middle portion is smaller than that of both ends. The details of this configuration are explained in the 20th
The figure shows 711. In FIG. 20, at 1:X, 60A is a cover member made of a rubber material, and 601) is a cylindrical core member whose middle part is smaller than both ends. In the core IJ60D,
By covering the pipe-shaped cover member 60A, the paper ejection roller 6 ( ) is formed. As a result, it is not necessary to integrally mold such a shape with the rubber part 1 etc., making it relatively easy and inexpensive. It is possible to obtain a paper ejecting roller. Note that the groove 6 continuously provided at the edge of the recording paper 0-ra 600) or when the recording paper is ejected by the paper ejecting roller 60) , its terminal end can be hooked, and the opening (-paper can be secured) when the recording paper is not in the correct position.The shape of the core member 60D is as described above For example, even if the shape of the groove 6013 is extended as it is and the middle part is made smaller, a cylindrical shape can be obtained by covering it with a rubber material. ] When using an 8-bit recording device as 8″LT, see Figure 21.
Please refer to Figure 2. When using the device in an upright position, you can use it with the auto feeder 200 as shown in Figures 1 and 2.
- Thick paper such as a cylinder may be fed from the paper feed [-1] on the back of the device. ; 4-i. In the case of regular B paper that uses a feeder 1. ) The lid 1r) 2 can be used as a stacker for the discharged recording paper 2'. At this time, as shown in Figure 1 (,
. In addition, the upper cover 102 is used as a paper guide for feeding paper, and is used in a different manner from that used in 2. , Search and case when using upper cover 1 (] 2 as a stacker!
” ゛Then it becomes like 1. That is, the ejected paper is transported through the air to some extent by the strength of its own strainer 2, and first reaches the upper end of the container 102 where it touches the already stacked paper. The area is set near the portion 102A. As a result, only the leading edge of the recording paper that is ejected slides on top of the first layer of recording paper, etc., and sliding can be avoided as much as possible, making it possible to record with unfixed ink. Prevents the paper from collapsing. The configuration for this is 4E
In the case of this example, it is important that the upper end 102A is located near the common tangent of the paper feed 1' truck 36 and the paper discharge roller 60, and that the upper end 102B is 1:1. . Furthermore, it stops at one end 102Al, and !
! When the ends of the 12 sheets are completely discharged, they are stacked at the child position without any sliding movement. The configuration for this purpose is that the length of the paper ejection force surface of the top cover 102 (7 lengths from the top end +02A to the end 102B) is the requirement, '-. When recording paper is used and the paper is ejected almost horizontally in this example, its length is 6υ% to 110% of the length of the recording paper, more preferably 7D%-18[]%. '4iru. f, J'i'r, itd record 2 position configuration, or if the used thread 1'4- is different and the paper ejection direction is different from '-, then the first requirement of i11 should be taken into consideration] It is only necessary to set the length of the stacker to J. In addition, the iog shown in FIG. 21 and FIG.
It is possible to prevent recording paper from entering the paper feed 106. (Others) In addition, the 4 inventions are particularly inkjet distribution horn type, Baburji Jtka type recording/\rad, record 1? The device does not provide excellent efficacy. This method allows for high-density and high-definition recording.
- This is because it is expected that the layer fixation speed will be slow depending on the recording pattern. Regarding the principle (to a typical configuration of '), see, for example, U.S. Pat. No. 4,723,129, U.S. Pat.
It is preferable to use the basic principles described in the specification. This method can be applied to both the so-called on-demand type and continuous type, but in particular,
In the case of the on-demand type, the electrothermal transducer placed in the sheet or liquid path where the liquid (ink) is held corresponds to the recorded information, and the nucleate boiling is exceeded. By applying at least j drive signals that provide rapid temperatures of ±4, the electrothermal transducer generates thermal energy, causing film boiling on the thermally active surface of the recording head, resulting in the drive signals This is effective because bubbles in the liquid (ink) can be formed in one-to-one correspondence. The growth of this bubble,
The contraction causes ink to be ejected through the ejection opening to form at least one drop. When this drive signal is in the form of a pulse, the growth and contraction of the bubbles is carried out immediately and appropriately, so it is possible to eject the liquid (ink) with excellent responsiveness to TI'+, which is more preferable. This pulse-shaped drive signal and 1. Therefore, those described in U.S. Pat. No. 4,463,359 and U.S. Pat. No. 4,345,262 are suitable. Furthermore, if the conditions described in the specification of U.S. Pat. No. 4,313,124, which relates to the temperature increase rate of the heat acting surface, are adopted, even more excellent recording can be performed. In addition to the configuration of the recording head as disclosed in the above-mentioned specifications, there are U.S. Pat. No. 4,558,333 and U.S. Pat. No. 44,596 disclose a configuration in which a heat acting part is arranged in a bending region.
A configuration using the specification of No. 00 is also included in the present invention. In addition, Japanese Patent Application Laid-Open No. 9123670 discloses a configuration in which a common slit is used as a discharge part for a plurality of electrothermal transducers, and an aperture for absorbing heat energy waves. The effect rack of the present invention is also effective in a structure based on Japanese Patent Application Laid-Open No. 591/384.6i which discloses a structure in which a discharge part corresponds to a discharge part. In other words, regardless of the form of the recording head, recording can be performed reliably and efficiently. In addition, as shown in example 1, there is a serial type J-tube type that is replaceable and can be attached to the main body of the device to enable electrical connections to the main body of the device and supply of ink from the main body of the device. The present invention is effective when using a self-recording head or a cartridge-type recording head integrally mounted on the recording head itself as in the No example. Also, the type or number of recording heads installed -)
However, for example, in addition to the case where only one ink is provided to correspond to a single color ink, it is also possible to provide multiple inks with different recording colors and densities. In addition, the inkjet recording apparatus of the present invention may be used as an image output terminal for information processing equipment such as 5.-1 bicoaters, etc. Even if it takes the form of a facsimile device having a combined set-up device, or even a facsimile device having a transmitter/receiver, the present invention is applicable to the following 1-1. In other words, a gap made of an elastic member integrally formed with an ink communication member forming a suction path is provided, and the ink communication member on the gap side made of the elastic member is provided with a rigid sieve suction bow 1 system body side ink communication member. By combining these, the recording head ejection in the Jl-gap state [1 formation curve] has high leveling accuracy (
In addition to holding the cap, it is also possible to effectively equalize the gap with respect to the discharge forming surface during gearing.
