DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet recording apparatus which can be applied to a recording apparatus such as a printer, a copying machine, a facsimile, a word processor and the like generally used for office equipment, and more particularly to a recording area and a recording medium in a recording medium such as paper and sheet. The present invention relates to preliminary ejection control for stabilizing ink ejection of a head.

[0002]

2. Description of the Related Art A printer is well known as a recording apparatus for recording desired information such as characters and images on a recording medium such as paper or film. On the other hand, in devices such as word processors and personal computers that create and edit recorded information, the price of the devices has been reduced as the performance of the devices has been improved, and furthermore, scanners, video captures and CDRs have been developed.
Various types of information can be easily recorded by changing the color of an information input device such as an OM drive or the like or a recording device such as the above-described printer and reducing the price. In the use environment of such information processing devices and printers, in addition to the recording of documents and the like on conventional A- and B-size fixed-size paper, various recording information such as color images and characters on postcards and cards, etc. Are often recorded, and their uses are also diverse. In particular, records on postcards, cards, and the like have been increasingly used in homes and the like, and are increasingly expanding.

In a recording apparatus, a recording information forming area (hereinafter, referred to as a recording area) on a recording medium such as paper or film is smaller than the size of the recording medium, and an unrecordable area, that is, a margin is formed at an end of the recording medium. It is common to have.
The presence of these margins is a limitation when the size of the recording medium is small, for example, information such as the number of characters to be recorded is reduced, and a base image or the like cannot be recorded on a card or the like without margins.

In order to avoid this limitation, there is a case where recording information is created and recorded assuming a recording sheet having a recording area larger than a desired recording sheet. In many cases, recording is performed, and problems such as soiling of the recording device occur. In order to eliminate the above-mentioned limitations and to further avoid this inconvenience and further expand the use of the recording apparatus, conventionally, in a word processor or the like incorporating a recording apparatus, for example, a sheet made of PET or the like having a size larger than a postcard in advance is used. An example in which notches are provided in the recording area of the backing paper corresponding to the four corners of the postcard, the corners of the postcard are inserted into the notches of the backing paper and fixed, and the postcard is fed and recorded together with the backing paper. Is widely known.

On the other hand, recording apparatuses have been put to practical use in the form of mounting recording heads of various recording systems. The recording head includes a wire dot type, a thermal type, a thermal transfer type, an ink jet type, and the like. In particular, the ink-jet method has attracted attention as a quiet recording method in which the ink is directly ejected onto a recording medium and the running cost is low.

In such an ink jet recording apparatus, an ejection recovery process is usually performed in order to stably maintain a good ink ejection state of the recording head. As an example of the ejection recovery process, the ink is ejected from a predetermined nozzle by driving an energy generating element provided in the nozzle of the recording head and used for ejecting ink, causing bubbles and dust, which are ejection failure factors, Alternatively, there is a preliminary ejection for discharging ink which has become unsuitable for recording due to thickening. In general, a receiving member such as a cap or a preliminary ejection receiver is fixedly provided at a predetermined position facing the recording head in order to receive the ink discharged by the ejection recovery process. Especially,
In a serial recording apparatus that performs recording while operating a recording head, a receiving member for ejected ink is provided at one end outside the range scanned by the recording head at the time of recording or at one end between the one end and the maximum recording paper width. It is common to provide fixedly at both ends with the end.

[0007]

However, the conventional method for enlarging the recording area requires the operation of inserting the recording medium into the mount, and the preparation before the recording operation is complicated. Also, when performing recording on a large number of recording media, it is necessary to prepare a large number of mounts, and it is necessary to repeat the operation of inserting the desired number of recordable sheets into the mounts, which is complicated, and in practice, a large number of There is a problem that cannot be recorded.

In the case where recording media of various sizes are used in the same manner, for example, it is conceivable to provide a number of cutouts corresponding to the recording medium on one sheet of paper, or to prepare various kinds of paper. However, in any case, there is a problem that the size of the recording medium that can be handled is limited and the versatility is poor.

In the conventional example, PET is used as the material of the backing paper.
The use of such a film and the formation of the notch portion cause a problem that the user cannot easily obtain a substitute when the mount is accidentally damaged or lost, and lacks convenience.

On the other hand, a receiving member for the ink discharged in the ink jet recording apparatus is fixed to one end outside the range scanned by the recording head at the time of recording or to both ends of this one end and the other end through the maximum recording paper width. Since the recording head is provided, it is necessary to move the recording head to the position of the ink receiving member when performing preliminary ejection during recording, and particularly when a narrow recording medium is used, the moving distance to the preliminary ejection position is required. However, there is a problem that the time required for recording is long. As one method for solving this problem, the invention described in Japanese Patent Application Laid-Open No. H6-115097 has been proposed. However, the method of the proposed invention has a problem that the guide and support of the recording medium are not sufficient when feeding the recording medium.

An object of the present invention is to provide an ink jet recording apparatus capable of recording without margins and shortening the recording time by a simple operation and configuration in order to solve the above-mentioned problems.

[0012]

Reference numeral 801 denotes a printer driver for performing various settings related to the printing apparatus and instructing the printing apparatus according to the settings.

Next, the operation of this embodiment will be described with reference to FIGS. First, prior to the printing operation by the printing apparatus, the user of the printing apparatus sets a desired sheet S on the automatic feeding unit 1. The guide member 107 is moved in the direction of arrow B to the end of the sheet S together with the setting of the sheet S. As a result of this operation, the outer end of the guide member 207 provided on the platen portion 206 becomes the sheet S as shown in FIG.
Of the sheet S is set inside the other end of the sheet S by a distance L2 from the other end of the sheet S.

Further, in the case of this example, the user performs various settings relating to recording in the printer driver 801 of the electronic device 8 connected to the recording device prior to recording. The various settings related to recording include, for example, setting of color printing or monochrome printing, setting of the number of copies, setting of the size of a recording medium such as a sheet, and setting of the size of a recording area on a recording medium such as a sheet. There is a setting (that is, setting of a margin amount), a setting of a recording mode such as a so-called draft mode in which recording information is thinned, and the like. In this example, a predetermined size, such as A4 size, is set as the size of the recording medium, and the margin amount in the width direction of the recording medium is set to 0.

After these operations and settings, when an instruction to start recording is issued from the electronic device 8 connected to the recording apparatus, the recording apparatus operates according to the flow shown in FIG. When the recording start is instructed, first, the detection state of the paper sensor 516 is checked (step S1). If it is determined by the paper sensor 516 that there is a sheet S, it is determined that the sheet S has been erroneously fed, and the conveying roller 201 is operated by a predetermined amount to discharge the sheet S out of the recording apparatus (step S2). . After the discharging operation in step S2 or when the sheet S does not exist, feeding of the sheet S from the automatic feeding unit 1 is started (step S3). The sheet S is fed by being separated from the bundle 105 on which the sheets S are stacked by rotation of the separation roller 104, and after passing through the paper sensor 516.
(Steps S4 and S5). When the paper is fed by an amount corresponding to a predetermined distance after passing through the paper sensor, the conveying roller 20
1 starts rotating by the transport motor 515, the sheet S is nipped by the transport roller 201 and the pinch roller 202, and transported to a predetermined recording start position (step S).
6). At this time, the separation roller 104 of the automatic feeding unit 1 is configured such that a portion other than the semicircular arc portion faces the sheet S, and is separated from the sheet S.

When the sheet S is conveyed to a predetermined position,
In preparation for the preliminary ejection prior to recording by the recording head, the carriage 402 is moved to the preliminary ejection position 2 on the guide member 106 side.
(Step S7). Here, the ejection recovery processing other than the preliminary ejection, for example, the operation of sucking ink from the recording head by the ejection recovery processing device is not particularly shown, but is performed as appropriate immediately after a recording start instruction is given. The preliminary ejection position 2 is set at the guide member 106 of the sheet S.
Is provided outside the sheet in the width direction of the sheet, and in this example, provided about 10 mm outside the sheet end (distance L
4) After the carriage moves to the preliminary ejection position 2, preliminary ejection is performed (step S8), and recording is started (step S9).

When printing is started, printing is performed while monitoring whether or not it is the timing of preliminary ejection until printing end is commanded (step S10). At the time of printing, in the present example, the blank amount in the sheet width direction is set to 0, so that ink is ejected from the nozzles 410 of the print head 401 and printing is performed over the entire area of the sheet S in the width direction according to desired print information. . At this time, at both ends in the width direction of the sheet S, the ink mist due to the ejection of the ink, an error between the set size in the width direction of the sheet and the actual size, an error in the recording position of the carriage 402, etc. The ink droplets scattered outward are received by an ink receiving portion 210 provided on the platen portion 206.

When the timing of the preliminary ejection comes during printing, a judgment for selecting the position of the preliminary ejection is made (step S11). In the case of this example, the selection of the preliminary ejection position is determined by selecting the preliminary ejection position 2 when the carriage 402 is moving in the direction of arrow B2 in FIG. 6 or before moving in the direction of arrow B1. Moving or arrow B2
In the state before the movement in the direction is started, the preliminary ejection position 1 is selected.

The carriage 402 is moved to the position selected here.
Moves (steps S12 and S13), and the preliminary ejection is performed (step S14). Here, the preliminary ejection position 1 is determined according to the size of the recording medium such as a sheet, particularly the width in the width direction, which is set by the user prior to a series of recording operations. A distance L3 in the sheet width direction from the end of the sheet on the guide member 107 side is set in advance at a position about 10 mm outside. The MPU 506 of the printing apparatus sets the dimension L in the width direction of the printing medium, the distance L3 from the end of the sheet on the guide member 107 side to the preliminary ejection position 1, and the home position 411 of the carriage.
The position L0 of the preliminary ejection position 1 is determined based on b, and the carriage 402 is moved to the preliminary ejection position 1. Next, in step S15, it is determined whether or not the end of the recording operation is instructed. When the end of the recording operation is instructed,
A predetermined end process (not shown) is executed to end a series of operations.

By operating as described above, the ink receiving members are provided outside the sheet S at both ends in the width direction of the sheet S so as to face the recording head 401 in accordance with the width of the sheet S. When printing by using the printing apparatus, the inside of the printing apparatus is not stained, and printing without margins can be performed over the entire width direction of the sheet.

Further, since the sheet is automatically supplied to the recording apparatus, recording on a plurality of sheets can be easily performed. Further, since no mount sheet is used, a simple and easy operation is performed. No recording can be performed and the recording area can be expanded.

Further, since the sheet guide members 207 and 208 are provided, the leading end of the sheet can be accurately guided to the discharge roller 203 when the sheet is conveyed, and the trailing end of the sheet can be supported and brought into contact with the ink receiving member 210. It can be transported without contamination by ink without any problem.

Further, since the sheet guide members 207 and 208 are always positioned on the back side of the sheet and inward in the sheet width direction according to the size of the sheet during recording, the sheet guide members 207 and 208 may be stained with ink. Absent. As a result, recording can be performed without soiling the sheet.

In this embodiment, the guide members 207 and 208 for guiding the sheet are provided inside the both ends of the recording medium at a predetermined distance, and the preliminary ejection position by the recording head is set at a predetermined position from both ends of the recording medium. Since the recording medium is provided outside through a distance, even if a slight error occurs between a preset recording medium size and an actual recording medium size, the recording area can be expanded without soiling the recording medium, and recording can be performed. Time can also be reduced.

Further, since the preliminary ejection position is provided in accordance with the width of the recording medium such as a sheet in the width direction and is provided near the end of the recording medium, the recording head can be moved to the preliminary ejection position efficiently. As a result, the recording time can be reduced.

(Embodiment 2) Next, another embodiment different from the previous embodiment will be described. In the previous embodiment, the preliminary ejection position 1
Is determined based on the width L of the printing medium set by the user prior to printing and the distance L3 from the end of the sheet on the guide member 107 side to the preliminary ejection position 1. In this embodiment, as shown in FIG. 8, a detection member 211 for detecting the position of the guide 207 is provided on the guide member 207, and the position of the movable guide member 207 is detected. Detection member 21
1 to the end of the guide member 207, a predetermined distance L1 from the guide member 107 to the end of the guide member 207, and the preliminary ejection position 1 from the guide member 107.
To the distance L3 (10 mm in this example).
, The preliminary ejection position 1 is determined.

For this reason, the carriage 402 is provided with a sensor section composed of a transmission type photo sensor or the like for detecting the home position and the position of the guide member 207 as the home sensor 411a, similarly to the previous embodiment, and performs recording. The MPU 506, which is a control unit of the apparatus, detects the position by the home sensor 411a passing through the detection member 211 and the home position detection member 411b as the carriage 402 scans. Further, the flow of the recording operation of the present embodiment can be applied as it is to the flow of the operation of the recording apparatus of FIG. 5 described above.

Even in the case of such a configuration, the ink receiving member is provided at the both ends in the width direction of the sheet so as to face the recording head 401 outside the sheet according to the sheet width, as in the previous embodiment. When recording is performed to both ends, the inside of the recording apparatus is not stained, and recording without margins can be performed over the entire area of the sheet in the width direction, so that the recording area can be expanded.

In this embodiment, since the position of the guide member 207 connected to the guide member 207 is detected and the preliminary ejection position is determined, a sheet having a size different from the size set by the user prior to recording is set. Even if it is used erroneously, an accurate printing operation can be performed without providing a preliminary ejection position on a sheet to be printed, an efficient printing operation can be performed, and a printing time can be reduced.

In each of the configurations described above, the ink receiving section 210 provided on the platen section 206
However, the ink receiving portion 210 is covered with a mesh-shaped cover member or the like, and guide members 207 and 208 are provided on the cover member so that the recording head 401 is interposed through the cover member. It may be exposed.

Further, one of the guide members 207 provided on the platen portion 206 and the other of the guide members 208 are provided independently of each other, but the outer ends of the guide members 207 and 208 in the sheet width direction are recorded on the sheet. If it is provided inside the
The configuration is not particularly limited. For example, the movable guide member 207 is composed of a plurality of members as shown in FIG. 7 and a guide portion is provided on the guide member 207 indicated by a dotted line in the figure, and the guide member 207 can be stretched in the width direction of the sheet along the guide portion. Such a configuration can be easily considered.

The sheet guide member 2 described so far
Although the guide member 208 has been described as fixedly provided with respect to the guide members 07 and 208, the fixedly provided guide member 106 is provided to be movable in the width direction of the recording medium similarly to the guide member 107, and the guide member 208 is provided. Similarly to 207, a guide member 208 may be provided in connection with the guide member 106 so that the guide member 208 can be moved in the width direction of the recording medium with the movement of the guide member 106. Also in this case, the guide member 208 may have a configuration in which the outer end in the width direction of the recording medium is provided inside the end of the recording medium. Although the carriage 402 described above is configured to be driven by the DC motor 409 and the encoder 407, a pulse motor or the like may be used.

Although the preliminary ejection position 2 is provided on the guide member 106 side of the platen portion 206, it is provided outside the guide member 106 side of the platen portion 206, and an ink receiving portion and a discharge recovery (not shown) are separately provided at this position. A configuration may be adopted in which a cap or the like that covers the nozzles of the recording head provided in the processing apparatus is provided, and preliminary ejection is performed here.
