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 having a plurality of recording elements and a recording head semiconductor chip having a driving integrated circuit for outputting transferred serial data as parallel data to the recording elements. The present invention relates to a head and an ink jet recording apparatus.

[0002]

2. Description of the Related Art Conventionally, various recording apparatuses in which a plurality of recording elements are arranged in a line are known. This type of printing apparatus mounts several or dozens of driving integrated circuits on a same substrate that can be driven with dozens of printing elements as one block, and aligns image data corresponding to each printing element. Thus, arbitrary recording can be performed on a recording material such as paper. While these recording devices are highly desirable as printers for modern business offices and other office processing departments in that high-density, high-speed recording is possible, and even for personal use, further cost reduction or Development and improvement such as colorization are being planned.

[0003] Among such recording apparatuses, a liquid jet recording apparatus that performs recording by discharging ink from discharge ports arranged on recording elements as low-impact non-impact recording is known because of its structural characteristics. Therefore, high-speed recording is sufficiently possible, and realization of a low-cost color printer or the like is eagerly desired.

[0004]

However, in order to realize the colorization of the liquid jet recording apparatus, ink is used as a recording material. Therefore, the recording apparatus is separated into cartridges of a plurality of colors due to the necessity of separating an ink tank. The present situation is that the recording apparatus becomes large and the driving circuit and the like become complicated. FIG. 14 is a block diagram showing a circuit configuration of a conventional liquid jet recording apparatus adapted for color. 1005C, 1005Y, 1005M

By further ANDing the AND output of 034, the recording element can be energized for the output time.

However, when a cartridge of a plurality of colors is mounted on a carriage of a printer or the like with this configuration, the connection between the substrate side and the head or the apparatus becomes complicated, so that not only the printer becomes large, but also the number of contacts of the carriage increases. There are many factors that increase costs, such as the complexity of the drive circuit, and are directly linked to recording accuracy, recording reliability, and durability.
There are many points to be solved in the design and production of the recording device.

A large number of recording elements as means for generating heat for forming flying droplets are arranged in accordance with the pixel density, and a transistor array or signal amplifying means for selectively driving these recording elements is provided. By integrating a functional element array, such as a diode array, to which is added, reliably mounting a driving integrated circuit, etc., and efficiently producing the same, it is possible to maximize the features of the recording apparatus.

However, under the present circumstances, the functional element array is individually formed as a chip from the viewpoint of yield and ease of manufacture, or mounted on a substrate on which a recording element is arranged as a driving IC including the functional element. Thereafter, recording is performed by adhesively bonding to a component for forming a space filled with ink, such as a discharge port (orifice) for discharging ink to form a flying droplet and a thermal action chamber communicating with the discharge port. Since the head is manufactured, low efficiency in mass production cannot be avoided.

Further, with the increase in density, integration, and length of the recording element, the above points need to be further solved.

In the case of an apparatus for recording a plurality of colors, a recording head corresponding to each color is prepared, and image data is individually supplied from the apparatus side to each color head. The number of terminals has increased, leading to an increase in the size of the head and the device.

[0010]

FIGS. 5 and 6 are a perspective view and a sectional view, respectively, showing the nozzle configuration when the semiconductor chip described in FIGS. 2 and 3 is applied to a liquid jet recording head. The semiconductor chip 1003 is mounted on the upper surface of the ink supply unit 1006, and a thermal working chamber for ink is formed by the orifice plate 1001. Electrothermal conversion is performed by applying a recording current, and bubbles 1009 are generated by the energy. 1
Since the liquid chamber shown at 010 is filled with ink, 100
By the pressure of No. 9, the flying droplet 1008 is ejected from the ejection port 1002.

As described above, by adopting a structure in which the ink wraps around and is supplied from the back surface of the substrate (the back surface of the surface on which the recording elements are arranged), uneven distribution of heat on the substrate is alleviated. Stable recording can be performed.

Further, since the distance between the position where the recording elements are arranged and the ink supply chamber 43 can be made very short, the refill speed can be increased, and high-speed response of ink ejection can be achieved. be able to. Further, since the distance from the bubbling position (recording element) to the common liquid chamber 43 is short, and the spread at the portion connecting the flow path to the common liquid chamber 43 can be increased, the back wave generated at the time of bubbling is dispersed. Therefore, the influence of the crosstalk of the back wave between the nozzles can be reduced. In order to produce such an effect, the arrangement of the recording elements is preferably within 1000 μm from the edge of the substrate, more preferably 3 μm.
The location (distance) of the printing element is a distance from the common liquid chamber side end of the flow path to the center in the direction along the flow path of the printing element.

FIGS. 5 and 6 show an example of an ink jet recording head using the substrate of the present invention, in which ink is ejected in a direction perpendicular to the surface on which the recording elements are arranged. FIG. 18 shows an example of a recording head that discharges ink in a direction along a surface on which recording elements are arranged as the first embodiment. FIG. 18 is a partial sectional view thereof.

34Y and 1034M AND output,
By taking D, the recording element can be energized for the output time. According to the present invention, a small and inexpensive recording head or recording apparatus can be achieved by arranging recording elements of a plurality of colors on one semiconductor chip.

FIG. 15 is a driving timing chart in a circuit of a printing apparatus capable of performing color printing to which the present invention is applied. The most characteristic feature here is that, when an image data signal (SI) is input, image data of a plurality of colors are serially arranged. That is, in the present invention,
Instead of separately inputting image data of a plurality of colors, cyan, yellow,
3 colors (or 4) of magenta (black may be added)
) Is serially input in order. The serial image data of a plurality of colors is sequentially transferred in the shift register by the image data transfer clock (SCK) of (1), and the image data of each color is aligned corresponding to one line of the recording element of each color of the recording head.

The shift register section shown in FIG. 15 is connected to the latch circuit section, and can be energized to the recording element in accordance with the image data for the cycle time of the latch pulse signal (LAT).

Actually, the printing is performed by dividing the recording element for each color for the period of time during which the printing element can be driven. A signal for performing the division for this is an enable signal (1
034C, 1034Y, and 1034M), and by inputting this signal and the strobe signal 14 for setting the optimal drive time (pulse width suitable for the characteristics of the recording element) for recording of each color, During the pulse period, the recording element blocks divided into a plurality of colors can be selectively driven with a constant pulse width.

Even in the case where printing of a plurality of colors is performed at the drive timing as described above, there is no need to provide a separate signal line for each color, the number of wirings and pads is reduced, and a compact and low-priced printing head is used. Substrate and recording head can be obtained. In the above description, the case of three colors has been described. However, a case where more colors are supported or one color can be driven similarly. By configuring the monochrome recording in the same way as the color recording device,
It is possible to perform color and monochrome recording simply by changing the head on one printer. The discrimination between the color and monochrome of the printing apparatus can be made by, for example, putting an identification code in the serial data and feeding back the data from the printing apparatus to the printer. The recording device may be provided with a notch or the like, and the determination may be made by a detection mechanism of the printer.

(Related Technology) Here, a monochrome cartridge as a related technology used interchangeably with the recording head of the present invention described in the above embodiment will be described.

FIG. 2 shows a liquid jet recording apparatus constructed on the assumption that a monochrome cartridge is mounted on the carriage of a printer capable of performing color recording in place of the recording head of the present invention described in the above embodiment. It is a related art example. The components are the same as in the case of the color, and the difference is that there is no member related to ink supply separation of a plurality of colors.

FIG. 16 is a drive timing chart of the recording apparatus configured as shown in FIG. In the case of a color image, monochrome image data may be input serially with only black data. As for the division driving, the array of the printing elements is divided into a specific number and 1034 (1), 1034 (1).
(2) Input like 1034 (3).

By configuring the color and monochrome recording apparatuses in the same manner as described above, it is possible to perform color and monochrome recording simply by changing the mounting on one printer. For discrimination between color and monochrome of the recording device, for example, put an identification code in the serial data,
This is possible by feeding back the data output from the recording device to the printer. The determination may be made by a detection mechanism of the printer by providing a cut-out of the recording device or the like.

FIG. 7 shows another embodiment which enables high-speed printing by cascading semiconductor chips which can be realized by the present invention so as to correspond to each color or the same color.

The connection terminal pads 1004 of 1003Y and 1003C are cascaded by a connection member (wire bonding or the like is also possible) 1030. FIG. 13 shows a circuit block having such a configuration. Basically, the power supply terminal is shared and the signal series wiring terminals are cascaded. When connected in cascade, color image data corresponding to the total number of recording elements may be serially input for each color data, and monochrome image data may be serially input for the total number of recording elements. FIG. 17 shows a drive timing chart for driving the printing apparatus having this configuration.

By arranging the semiconductor chip recording element arrangement of the present invention in a staggered manner, a recording apparatus capable of higher-speed, higher-density printing as shown in FIG. 8 can be constructed. 1
A member or substrate for relaying the connection member of No. 030 is arranged on a member or substrate for holding the semiconductor chip. The recording apparatus having such a configuration has an advantage that when the recording element or the semiconductor chip is destroyed for some reason, the corresponding semiconductor chip can be replaced.

In addition, since the recording element and the functional element corresponding to the recording width of one line and the driving integrated circuit are structurally provided inside the surface of the same substrate, the reliability can be improved in that maintenance-free operation is possible. A high-density, high-speed full-line recording device capable of high-speed printing can be provided.

FIG. 9 is not a full line, but a recording element, a functional element, and a driving integrated circuit corresponding to several tens of semiconductor chips are structurally provided inside the surface of the same substrate, and the arrangement of the recording elements is changed. Liquid chambers 1031M, 1

Reference numeral 032C denotes magenta, yellow, and cyan ink supply tubes, respectively. Although not shown, a monochrome full-line liquid jet recording apparatus can be configured based on this configuration without dividing the liquid chamber.

FIG. 11 shows a full-line liquid jet recording apparatus according to the present invention in which recording elements, functional elements, and driving integrated circuits corresponding to several tens of semiconductor chips are structurally provided inside the surface on the same substrate.

And a recording device assembly. Reference numeral 200 denotes an ejection recovery unit, which is configured to face the printing apparatus assembly instead of the recording medium R in the ejection recovery processing, and includes a cap, an ink absorber, a wiping blade, and the like.

The typical structure and principle are described in, for example, US Pat. Nos. 4,723,129 and 4,740.
It is preferable to use the basic principle disclosed in the specification of Japanese Patent No. 796. This method is a so-called on-demand type,
Although it can be applied to any of the continuous-unias type, especially in the case of the on-demand type, the recording information is stored on the sheet holding the liquid (ink) or the electrothermal transducer arranged corresponding to the liquid path. By applying at least one drive signal corresponding to the above and giving a rapid temperature rise exceeding the nucleate boiling, heat energy is generated in the electrothermal transducer, and the film is boiled on the heat working surface of the recording head. This is effective because bubbles in liquid (ink) can be formed in one-to-one correspondence with the drive signal. By discharging the liquid (ink) through the discharge opening by the growth and contraction of the bubble, at least one droplet is formed. When the drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are performed immediately and appropriately, so that the ejection of a liquid (ink) having particularly excellent responsiveness can be achieved, which is more preferable. Examples of the drive signal in the form of a pulse include U.S. Pat. Nos. 4,463,359 and 4,345.
No. 262 are suitable. Further, if the conditions described in US Pat. No. 4,313,124 relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

As the configuration of the recording head, in addition to the combination of the discharge port, the liquid path, and the electrothermal converter (linear liquid flow path or right-angle liquid flow path) as disclosed in the above-mentioned respective specifications, U.S. Pat. No. 4,558,333 and U.S. Pat. No. 4,558,333 which disclose a configuration in which a heat acting portion is arranged in a bending region.
A configuration using the specification of Japanese Patent No. 459600 is also included in the present invention. In addition, JP-A-59-123670 discloses a configuration in which a common slit is used as a discharge portion of an electrothermal converter for a plurality of electrothermal converter pairs, and an opening for absorbing pressure waves of thermal energy. The present invention is also effective as a configuration based on Japanese Patent Application Laid-Open No. 59-138461, which discloses a configuration corresponding to a discharge unit.

Further, as a full line type recording head having a length corresponding to the width of the maximum recording medium that can be recorded by the recording apparatus, a combination of a plurality of recording heads as disclosed in the above-mentioned specification is used. Either a configuration that satisfies the length or a configuration as one integrally formed recording head may be used, but the present invention can more effectively exert the above-described effects.

In addition, an exchangeable chip-type recording head, which is electrically connected to the apparatus main body and can supply ink from the apparatus main body, or is integrated with the recording head itself when the apparatus is mounted on the apparatus main body. The present invention is also effective when a cartridge-type recording head provided in a fixed manner is used.

It is preferable to add recovery means for the printhead, preliminary auxiliary means, and the like provided as components of the printing apparatus of the present invention since the effects of the present invention can be further stabilized. More specifically, pre-heating of the recording head by a capping unit, a cleaning unit, a pressurizing or suctioning unit, an electrothermal converter, another heating element, or a combination thereof. It is also effective to perform a preliminary ejection mode in which ejection is performed separately from the means and printing to perform stable printing.

Further, the recording mode of the recording apparatus is not limited to the recording mode of only the mainstream color such as black, but may be a single recording head or a combination of plural recording heads. The present invention is also very effective for an apparatus provided with at least one of full colors by color mixture.

[0047]

As described above, in the ink jet recording head and the ink jet recording apparatus provided with the recording head semiconductor chip of the present invention, the number of terminals for exchanging image data with the recording apparatus side can be increased without increasing the number of terminals.
Color recording can be easily performed only by serially inputting serial image data corresponding to a plurality of colors.

Each color is defined as one block for a plurality of colors.
By dividing and arranging, the recording elements for each color can be driven in order.

In order to provide a highly reliable recording apparatus, a plurality of recording elements, functional elements, and a driving integrated circuit are integrated as semiconductor chips inside the surface of the same substrate, so that the yield is high and the image signal is high. A semiconductor chip for a recording head or the like which can easily transfer the data can be provided. Particularly, in a configuration in which one chip corresponds to a plurality of colors, the recording elements are separately arranged to separate the colors of ink, while the recording data corresponding to each color is supplied as serial data into the chip. In addition, it is possible to provide an ink jet head which can handle a plurality of ink colors and has fewer data signal lines.

In the configuration in which the semiconductor chips are cascaded for each color as described above, a recording device capable of high-density and high-speed printing can be provided, and a low-cost color printer or the like can be realized.

It is to be noted that the present invention can be used without being limited by the use and resolution of the recording apparatus. In the colorization described in the embodiment, cyan, magenta,
Although the configuration example is shown by three colors of yellow, it is needless to say that the same effect can be obtained even if the monochrome part is recorded only with black and colorized with four colors of cyan, magenta, yellow and black.

Further, by forming a shift register, a driver transistor, and the like, which are conventionally arranged at a position distant from the substrate on which the recording element is provided, on the substrate, the wiring resistance is reduced, thereby making it possible to reduce the wiring resistance. , Energy loss can be suppressed.

In particular, an ink jet using heat requires a large current of several hundreds of milliamps as a driving current in principle to foam a liquid, and is therefore very effective.

The effect is particularly great in a battery-driven device.
