Abstract

PURPOSE:To enable cleaning of a recording surface of a recording without need for any special driving means, reduce the number of component parts and contrive a simpler construction and a lower cost, by affixing a cleaning member for the recording surface of the recording medium to a consumable member detachably mounted on a carriage. CONSTITUTION:A recording head 6 for recording images on a recording medium S and a carriage 7 moved with the head 6 mounted thereon are provided. A cleaning member 13 for a recording surface of the recording medium S is affixed to a consumable member 9 detachably mounted on the carriage 7. Therefore, the recording medium S being fed is subjected to printing of images thereon by the head 6 mounted on the carriage 7 being moved. Prior to the printing, the cleaning member 13 affixed to the consumable member 9 mounted on the carriage 7 makes contact with the recording medium S to remove refuse from the medium S.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention is applicable to wire tod printers, thermal transfer printers,
The present invention relates to an image recording apparatus such as an inkjet printer, and more particularly to an image recording apparatus including a cleaning member that cleans a surface of a recording medium on which an image is recorded.

(B) Prior Art Conventionally, image recording apparatuses have been known that are equipped with a cleaning member that cleans the surface of a recording medium on which an image is printed. to clean the surface of the recording medium.

(c) Problems to be Solved by the Invention Incidentally, the above-described image forming apparatus requires a driving means for driving the cleaning member, which makes the apparatus complicated and increases cost.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a one-image recording device that does not require a driving means for driving a cleaning member, has a simple configuration, and eliminates the above-mentioned problems.

(b) Means for Solving the Problems The present invention has been made in view of the above-mentioned circumstances, and for example, as shown with reference to FIGS.
), and a carriage (7) that carries the recording head (6) and moves, the surface of the recording medium on which the image is recorded. The present invention is characterized in that a cleaning member (13) for cleaning is attached to a removable life member (9) mounted on the carriage (7).

1 Operation Based on the above configuration, the recording medium (S
), an image is printed by a recording head (6) mounted on a moving carriage (7). At this time, prior to printing, the cleaning member (13) attached to the lifetime member (9) mounted on the carriage (7) comes into contact with the recording medium (S) and Clean up trash.

Note that the above-mentioned symbols are shown for reference and do not limit the configuration in any way.

(F) Examples Examples of the present invention will be described below with reference to the drawings.

As shown in FIG. 2, the inkjet printer 1 has a platen 3 in a body 2 that supports a sheet S as a recording medium. On the front side of the platen 3, two shafts 5, 5 are supported horizontally and approximately parallel to each other, and a carriage 7 on which an inkjet head 6 is mounted slides on these shafts 5, 5. Supported for free movement.

Further, the inkjet head 6 and carriage 7 are
As shown in detail in FIGS. 1(al) and (b), an ink tank 9 is mounted on the carriage 7, and the tank 9 is
Positioning protrusions 1 protruding from both sides of the front end of the carriage 7
The tank 9 is positioned by fitting a protrusion 11 projecting from the rear center of the tank 9 into a hole (not shown) drilled in the tank 9. Further, an opening 12 is formed at the tip of the ink tank 9, and the inkjet head 6 is positioned in the opening 12.

Adhesive rollers 13, 13 as cleaning members are rotatably supported at the left and right ends of the tank 9, and these adhesive rollers 13, 13 are made of urethane rubber,
It is made of a sticky rubber material such as butyl rubber. Further, these adhesive rollers 13, 13 are supported so as to be able to move back and forth, and only the adhesive roller 13 on the upstream side in the moving direction of the inkjet head 6 contacts the sheet S to print on the sheet S by means of an unillustrated advancing and retreating means. The surface is supposed to be cleaned. On the other hand, at the center of the rear end of the carriage 7, there is provided an ink supply needle 15 that supplies ink from the ink tank 9 to a sub-tank (not shown) that supplies ink to the ink jet head 6.

Further, as shown in detail in FIG. 3, the ink tank 9 has a hole 16 bored in the lower part of the main body 9a.
A rubber stopper 17a of the ink bag 17 is fitted into the ink bag 17, and when the tank 9 is mounted on the carriage 7, the yellow ink supply needle 15 installed upright on the carriage 7 is inserted into the rubber stopper 1.
The ink in the ink bag 17 is supplied to the sub-tank by passing through the ink tank 7a.

Since this embodiment has a hypothetical configuration, the sheet S sent from upstream is conveyed to the platen 3, and the sheet S is conveyed to the shaft 5. An image is printed by an inkjet head 6 mounted on a carriage 7 that slides on S. On this occasion,
Only the adhesive roller 13 on the upstream side in the moving direction of the carriage 7 is brought into contact with the sheet 1-8 by a forward/backward means (not shown) that moves together with the carriage 7, and the roller 13 removes paper dust and paper from the surface of the sheet S on which the image will be printed. Debris such as fiber fluff is removed. Further, when the carriage 7 reaches one end of the sheet S and reverses, the adhesive rollers 13 and 13 are
The forward and backward movement of is also reversed, and only the adhesive path roller 13 on the upstream side in the carriage movement direction comes into contact with the sheet S to clean the surface of the sheet S, as described above.

In the above-mentioned embodiment, the adhesive roller 13° 13 is moved back and forth by the advancing and retracting means to prevent the adhesive roller 13 from coming into contact with the printed sheet S surface, but the invention is not limited to this. As shown, an adhesive roller 13a that is lower than the nozzle hole of the inkjet head 6a may be used, and in this case, the advancing/retracting means can be omitted.

Further, in the above embodiment, the ink tank 9 was used as the life member, but the present invention is not limited to this, and as shown in FIG. 4, an ink jet head 6a having a built-in ink tank may be used. Note that 19 in the figure is a jig for fixing the inkjet head 6a.

In the above-mentioned embodiment, the sheet 1- is used as the recording medium.
Although the explanation is made using paper S, the paper is not limited to this, and roll paper or fanfold paper may also be used. Since it has a cleaning member that
The cleaning member can be moved without requiring any special driving means to clean the image recording surface of the recording medium, thereby reducing the number of parts and simplifying the apparatus and reducing costs.
