Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording apparatus, and more particularly, to a recording apparatus having a detachable recording head.

[0002]

2. Description of the Related Art In a recording apparatus such as an ink jet printer, there is a recording apparatus in which a recording head is mounted on a carriage which reciprocates in a paper width direction, and this recording head can be detachably replaced when ink is consumed. Although not shown, the recording head attaching / detaching mechanism simply mounts the recording head by pushing the recording head into the attaching position, and the recording head temporarily placed on the carriage is moved to the attaching position by a lever operation and fixed. There are things.

FIG. 13 is a perspective view showing an example of the latter recording apparatus. The recording apparatus includes a recording head 40 on a recording medium (recording paper or the like) (not shown) sent from a paper feeding unit 39.
The recording is performed by ejecting ink droplets from the printer. The recording head 40 is mounted on a carriage 41, and the carriage 41 moves in a direction along the guide shaft 42 (the left-right direction in the drawing).
The carriage drive motor 43
Is transmitted via the carriage drive belt 44 and reciprocates integrally with the recording head 40. The recording head 40 can be attached to and detached from the carriage 41 by pulling down the operation lever 45 while the recording head 40 is temporarily placed on the carriage 41 slightly to the left of FIG. Is moved and fixed to the mounting position (the position shown in FIG. 13).

[0004]

Of the conventional examples, in the former case, the mounting operation of the recording head to the carriage is completed by only one operation of pushing in with the recording head, so that the mounting operation is simple. However, even if the recording head is pushed in a wrong position or direction, the installation operator may apply a large force without noticing, in which case an excessive load may be applied to the recording head and the carriage, causing damage. There is.

In the case of the latter, such as the configuration shown in FIG. 13, the operator can intuitively understand the members to be operated, the operating force, the operating direction, and the feeling of completion of the operation.
And the risk that the carriage 41 will be damaged by an excessive load. However, the recording head 40 and the carriage 4
1 is subject to the following restrictions with respect to an electrical contact method for establishing electrical continuity between them.

As schematically shown in FIG. 14A, when electrical contact portions 49 and 50 are provided on a surface substantially parallel to the direction in which the recording head 48 moves on the carriage 47. Then, the recording head 48 moves further after the electrical contact portions 49 and 50 come into contact with each other. When the contacts of the electrical contact portions 49 and 50 are rubbed, they may be worn out, short-circuited, or the flexible cable 56 forming the position of the electrical contact portion may be greatly bent and become brittle. Further, in order to enhance the reliability of conduction, the electrical contact portions 50 are designed to be in a state of being pressed to some extent using the rubber pad 51 or the like.
If the recording head 48 further moves toward the mounting position 57 after the zeros have come into contact with each other, the rubber pad 51 is dragged, causing deformation. If the rubber pad 51 cannot return to the original shape over time, the reliability of electrical conduction deteriorates.

In order to solve such a problem, FIG.
As shown in (b), an electric contact portion 54 is provided on a side surface which is substantially upright with respect to the direction in which the recording head 52 moves on the carriage 53 when the recording head 52 is mounted. The electrical contact portion 55 is provided on the surface facing the. Then, at the final stage of the work of attaching the recording head 52 to the carriage 53, when reaching the vicinity of the attachment position 58, the two contact portions 54,
55 are in contact with each other to establish conduction. With this configuration, there is no possibility that the rubber pad 59 or the flexible cable 60 is deformed or damaged.

As described above, in order to ensure the reliability of conduction, the position of the electrical contact portion is limited according to the moving direction of the recording head on the carriage, which is a design constraint. However, in the case of, for example, an ink jet recording apparatus, there is a possibility that an ink may be scattered at a position of an electrical contact portion, and this ink stain may cause an electric short circuit. Therefore, it is desirable that the electrical contact portion can be arranged at an arbitrary position regardless of the moving direction of the recording head on the carriage so that the electrical contact portion can be arranged at a position where the ink stain is unlikely to occur.

SUMMARY OF THE INVENTION An object of the present invention is to provide a recording apparatus which reduces the risk of damage to a carriage and a recording head and has less design restrictions than in the past.

Further, a cam portion provided on the lift-up member and engaged with the electric contact portion to retreat in conjunction with the movement of the operation lever from the lock position to the release position may be provided.

The pressing section may be urged toward the recording head at the mounting position.

[0015] The fixing portion may be retracted from a position where it can come into contact with the recording head in conjunction with the movement of the operation lever from the lock position to the release position.

In some cases, the fixed portion is composed of a rotating member having a first contact portion that contacts the recording head and a second contact portion that contacts a cam portion provided on the carriage frame.

Further, in conjunction with the operation lever, when the operation lever is at the lock position, it protrudes into the movement locus when the recording head is mounted, and when the operation lever is at the open position, it retreats out of the movement locus. It may have a member.

The hole 9a is fitted to the pin 7 of the operation lever 6, and the link member 8 is swingably mounted. The pin 10 is fitted to the hole 9b of the link member 8, and the lift-up member 11 swings. It is provided as possible. The carriage frame 2 is provided with a rail 21 extending in the up-down direction in FIG. 2, and the groove 11 a of the lift-up member 11 is fitted to the rail 21. The swing of the operation lever 6 causes the link member 8 and the lift-up member 11 to move.
Are linked to each other. In the present embodiment, a state in which the operation lever 6 is pulled down (a state in FIG. 4).
Is a lock position, and a state in which it is pulled up (a state in FIG. 6) is an open position. The state shown in FIG. 5 shows a state during movement between the lock position and the release position.

The carriage 1 has an electrical contact 12
Is provided, and the configuration is as follows. A rubber pad 14 is held by a rubber pad holder 13, and a flexible cable 15 is provided on the front surface of the rubber pad 14. The rubber pad holder 13 is urged by a pressure spring 16 toward the electrical contact portion 18 of the recording head 4. One end of the flexible cable 15 is provided with a contact 17 for contacting an electrical contact portion 18 of the recording head 4 described later.
Alternatively, it is fixed on an electric board provided in the recording apparatus main body, and is connected between the recording apparatus main body and the recording head so that electric signals can be transmitted and received.

FIG. 4 shows a state in which the recording head 4 is completely fixed to the carriage 1. The recording head 4 is fixed to the carriage frame 2 by locking the lower surface 19 a of the fixing portion 19 of the lift-up member 11 to the upper surface 20 a of the step portion 20 of the recording head 4. Further, the flexible cable 15 of the electric contact portion 12 on the carriage 1 side and the electric contact portion 18 on the side surface of the recording head 4 are brought into pressure contact with each other under the pressure of the pressurizing spring 16, so that conduction is established. ing.

Next, the process of removing the recording head 4 from the fixed state shown in FIG. 4 will be described with reference to FIGS. When removing the recording head 4, the operator operates the operation lever 6.
Is lifted upward, the lift-up member 11 receives a force to swing through the link member 8. However, since the groove is fitted in the rail 21, the movement is restricted, and the lift-up member 11 Rise along. Along with this, as shown in FIG. 5, the fixing portion 19 separates from the step portion 20, and the flat portion (engaging portion) of the lift-up member 11
Reference numeral 22 contacts the lower surface of the hook 23 of the recording head 4.

Further, the tapered upper surface of the cam portion 24 of the lift-up member 11 shown in FIG.
3 retreats against the pressure of the pressure spring 16. This will be described in detail with reference to FIGS. In FIG. 4, the tapered lower surface of the cam portion 25 and the tapered upper surface of the lift-up member 11 (shown by broken lines in FIGS.
Numeral 4 is pressed against the recording head 4 with the rubber pad 14 and the electrical contact portion 18 interposed therebetween by the reaction force of the pressure spring 16.

Next, in FIG. 5 showing a state in which the lift-up member is slightly raised by the lever operation, the cam portion 24 is also raised at the same time as the lift-up member 11 is raised. Contact. The lift-up member 11 includes a straight groove 11a provided on a side surface.
Are engaged with the rails 21 and can be moved only up and down and are restrained at the front and rear.
Rises, the cam portion 25 can move only forward and backward and is restrained up and down, and thus gradually retreats along the tapered upper surface of the cam portion 24 while resisting the reaction force of the pressing spring. With this retreat, the electrical contact with the recording head 4 is released.

FIG. 6 shows the behavior when the lever is further raised.
Indicated by The tapered surfaces of the cam portions 24 and 25 may be extended as they are, and the cam portion 25 may be retracted more and more as the cam portion 24 rises. However, in actuality, there is a space, and it is not necessary to retreat more than necessary. In the embodiment, after the electrical contact is released and the recording head 4 is lowered to a region where there is no interference when the recording head 4 is attached or detached, the cam portions 24 and 25 are interfered with the tapered surfaces to the region so as not to move back and forth. After retreating, it was configured to have a vertical surface or a gentle cam surface.

Thus, the preparation for removing the recording head 4 is completed.

Subsequently, when the operating lever 6 is further pulled up, the lift-up member 11 further rises via the link member 8, and as shown in FIG.
Pushes up the lower surface 23 a of the hook portion 23, whereby the recording head 4 is lifted from the carriage frame 2. In this state, the operator can easily take out the recording head. When the electrical contact portion 12 is retracted, the conduction is released and the recording head 4 is not likely to be caught, and the locking between the step portion 20 and the fixing portion 19 is released. The recording head 4 can be easily removed without applying an excessive load to or damage to each member of the carriage, because the recording head 4 is half-projected upward. There is no danger of rubbing the contacts of the electrical contact portions 12 and 18.

In the example shown in FIG. 6, the recording head 4 rotates around the lower left end as a fulcrum, and
Although the recording head 4 is configured to protrude outward, the recording head 4 may be configured to be removed directly above the carriage frame 2.

In this embodiment, when the recording head 4 is mounted on the carriage 1, the procedure is the reverse of that described above. Briefly, first, as shown in FIG. 6, the recording head 4 is placed above a predetermined mounting position in a state where the operation lever 6 is completely pulled up. In this state, the hook portion 23 is placed on the flat portion 12 of the lift-up portion 11.

Therefore, the recording head moves stably at a relatively uniform speed. In particular, when the recording head is mounted, it is lowered by its own weight in the first embodiment, but in this embodiment, it can be lowered more reliably by the pressure spring. The recording head 4 can be securely mounted even in the event of an abnormality, such as when the carriage 1 is caught in the carriage 1. And, as described above, at least the operation lever 6
In the state in which the lift-up member 26 has reached the vicinity of the lock position (pull-down completion position) shown in FIG. 7, the spring force of the pressure spring 28 urges the lift-up member 26 in the pulling-up direction. become. The pin 7 that engages with the hole of the link member 8 is disposed on the right side of the center line of the pin 5 in FIG. 7. When the link member 8 is pushed upward, the operation lever 6 is turned around the pin 5. Try to rotate clockwise. This means that the operation lever 6 is biased to the lock position. That is, even if the operation lever 6 cannot be pulled down to the end manually by the reaction force of the pressure spring 28, the operation lever 6 is automatically retracted to the lock position.

Next, a third embodiment shown in FIGS. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the fixed state of the recording head 4 shown in FIG.
The second contact portion 30b does not contact a position other than the cam portion 33 of the carriage frame 32, and the first contact portion 30a contacts and locks the step portion 20 of the recording head 4. When the operation lever 6 is pulled up from this state, the lift-up member 20 rises via the link member 8. At this time,
The second contact portion 30b of the rotating member 31 contacts the cam portion 33 and rotates, and the first contact portion 30a moves away from the step portion 20 of the recording head 4. Further, the flat portion 22 pushes up the hook portion 23 of the recording head 4, and the electrical contact portions 12, 18 are released as in the first embodiment. As a result, the recording head 4 can be easily removed. As shown in FIG. 10, the shape and the center of rotation of the rotating member 31 are such that the first contact portion 30 a is separated from the step portion 20 when the second contact portion 30 b contacts the cam portion 33. The rotation member 31 is set to rotate. According to the present embodiment, when the recording head 4 is attached or detached, the lift-up member 29 is attached.
Eliminates the risk of getting stuck on.

Next, a fourth embodiment shown in FIGS. 11 and 12 will be described. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The link member 34 includes the hook 23 of the recording head 4.
Is provided with a projection 35 which can be engaged with the projection.

The projection 35 is a member for preventing the recording head 4 from being erroneously inserted. As shown in FIG. 11, the projection 35 projects toward the recording head 4 when the operating lever 6 is in the locked position where the operation lever 6 is pulled down. . The projection 35 does not contact the recording head 4 in the fixed state, and does not hinder the recording operation. On the other hand, when the recording head 4 is not mounted and the operation lever 6 is in the lock position, when the recording head 4A is newly inserted, the hook portion 23 of the recording head 4A comes into contact with the projection 35, Cannot insert.
When the operation lever 6 is pulled down, the pressing spring 16
As a result, the rubber pad holder 13, rubber pad 14, and flexible cable 15 protrude toward the recording head. When the recording head is inserted in this state, the rubber pad 1
4 may be deformed or the contact 17 of the flexible cable (see FIG. 2) may be rubbed or short-circuited. However, in the present embodiment, the recording head is prevented from being erroneously inserted in a state where the operation lever 6 is pulled down, and the electrical contact portion 12 is prevented from being damaged.

As shown in FIG. 12, when the operation lever 6 is in the open position where the operation lever 6 is pulled up, the link member 34 swings and the projection 35 does not contact the hook 35, and the recording head 4A is inserted. It is possible. At this time, the cam portion 24 of the lift-up member 11 and the cam portion 25 of the rubber pad holder 13
And the electrical contact portion 12 is retracted, so that the end surface of the recording head is not rubbed and damaged.

In this embodiment, the projection 35 is provided on the link member 34 as a recording head erroneous insertion preventing member. However, the projection 35 can be formed on other members. What is necessary is just to arrange so that it can move between the position where it swings and engages with the hook member and the position where it does not engage.

[0045]

As described above, according to the present invention, since the position of the electrical contact portion can be set arbitrarily regardless of the moving direction of the recording head on the carriage, the degree of freedom in design is increased. Then, there is no possibility of damaging the electrical contact portion, and the reliability and durability of conduction are improved.

If the electrical contact portion is configured to be urged, a certain positional error can be tolerated, and an appropriate contact pressure can be generated, so that accurate control can be performed.

When the pressure portion is biased, the recording head moves stably and reliably at a relatively uniform speed.
Further, since the operation lever can be reliably moved to the correct lock position, the reliability of mounting the recording head is improved, and the operational feeling is improved.

When the operation lever is moved from the lock position to the release position, the fixing portion is retracted from a position where it can be brought into contact with the recording head, so that the recording head can be securely and smoothly attached and detached, and the operational feeling is improved. .

When the carriage is provided with the erroneous insertion preventing member, it is possible to prevent the carriage and the recording head from being damaged when trying to mount the recording head when the operation lever is at the lock position.
