Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inkjet recording apparatus, and more particularly to an inkjet recording apparatus used for a terminal device of information equipment.

[0002]

2. Description of the Related Art In recent years, as the form of a computer has been reduced from a desktop type to a laptop type or a notebook size type, a printer is required to be excellent in portability and small in size. Under these circumstances, inkjet printers that use a disposable ink cartridge integrated head are used as printers for laptop and notebook computers because they are easy to use and can be easily downsized. It is getting attention.

As shown in FIG. 5, a conventional ink jet printer has a carriage 1 in which a monochrome ink cartridge integrated head (hereinafter referred to as "cartridge") 2 and a multi-color cartridge 3 are mounted, and a carriage for printing. Belt 51 for moving 1 to a predetermined position on printing paper 7, motor 5 as a driving source thereof, shafts 61, 62 for guiding the moving direction of carriage 1, heads 21 of cartridges 2, 3 when printing is not performed. Caps 42 and 43 for capping respectively, 31 and caps 42 and 43 for that purpose
And a cap holder 4 for pressing the head against the heads 21 and 31.

In addition to the print heads 21 and 31, the cartridges 2 and 3 include an ink storage portion and electrical contacts for receiving a drive signal so that they can be replaced when the ink is exhausted. It is configured to be removable. When printing is not performed, the carriage 1 is at the standby position, and the cap holder 4 moves in the direction A in order to prevent the ink ejection openings of the heads 21 and 31 from drying and clogging.
Caps 42 and 43 are pressed against heads 21 and 31, and capping is performed. At the time of printing, the cap holder 4 moves in the direction opposite to A to cover the heads 21, 31 with the caps 42, 43.
The carriage 1 prints on the paper 7 while reciprocating along the shafts 61 and 62 by the action of the belt 51 and the motor 5.

Since the head 21 of the cartridge 2 has, for example, 48 nozzles, a monochrome character font can be printed by scanning the carriage 1 once. The cartridge 3 is for multi-color, and the ink storage section is divided into three corresponding to the three inks of yellow, magenta, and cyan, and correspondingly, the 48 nozzles of the head 31 are also divided into three. Has been done. Therefore, a multi-color character font can be printed by scanning the carriage 1 three times.

[0006]

However, in the conventional ink jet printer, since the control circuit portion is provided in the cartridge, there is a problem that the cartridge becomes large.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an ink jet recording apparatus which can solve the above-mentioned conventional problems and can downsize a cartridge, which has high reliability and is easy to manufacture and maintain.

[0008]

In order to solve the above problems, according to the present invention, there is provided a cartridge comprising a head portion having an ink ejection port group for ejecting ink and an ink accommodating portion for accommodating the ink, and a cartridge. A control circuit unit of an inkjet recording apparatus including a carriage to be mounted and a control circuit unit mounted on the carriage and electrically connected to the cartridge is sandwiched between the carriage and the cartridge.
The configuration is such that they are placed close together.

With this construction, the size of the cartridge can be reduced because the control circuit portion is not provided in the cartridge, and the carriage has a relatively large space and a large degree of freedom in shape. It is possible to mount the control circuit unit so as not to hinder the miniaturization of the carriage accompanying the miniaturization of the cartridge. Therefore, the cartridge and the carriage can be downsized as a whole, and the ink jet recording apparatus can be downsized. Furthermore, by removing the relatively expensive control circuit unit from the cartridge and providing it on the carriage, the control circuit unit that was conventionally discarded when the cartridge was replaced can be used semipermanently regardless of the cartridge replacement. . In that connection, the cost of the cartridge can be reduced.

Further, when the cartridge is attached or detached, the contact is exposed on the surface of the cartridge which is easily touched by the user, and the user can easily touch the contact at the time of attachment / detachment. No
In addition, it is easy to bring the contact to a part that is difficult for the user to touch, and since it can be installed inside so that it is not exposed to the surface, static electricity generated when the user touches the contact. It is possible to easily prevent the control circuit unit from being damaged by the influence of the above.

In the case of the double speed mode, the two cartridges are driven at the same time and two lines are printed together to double the printing speed.

When it is detected that two cartridges of the same type are mounted and at the same time that the switch 86 is on, printing is performed in the double precision mode using the cartridge of that type. To do. In the double-precision mode, the print control unit 80 receives data from the font ROM 82 that stores double-resolution characters and the dither ROM 84 that stores double-resolution graphic patterns, and stores them in the upper and lower cartridges. On the other hand, the head driver 87 is configured so that the print signal corresponding to half the ink ejection port pitch is sent with the timing shifted.
Supply the print signal to. At the same time, the paper feed motor 88 is driven so as to repeat the operation of feeding the paper by half the ink ejection port pitch and the operation of feeding the paper at the print line pitch. By doing so, it is possible to print with double the resolution.

When it is detected that two different kinds of cartridges are mounted, the print mode is a mixed mode of black and color. LED1 and LED2
Contains a two-color light emitting diode that selectively emits two colors, red and green. LED1 emits red light when the type of cartridge installed in the upper stage is a black cartridge, and emits green light when a multi-color cartridge is used. To do. Also LED
No. 2 emits red light when the lower cartridge is a black cartridge, and emits green light when the cartridge is a multi-color cartridge. The method of detecting the type of cartridge is not limited to the method described above, and other methods may be used. For example,
A difference in the outer shape of the cartridge or a detection marker or the like provided in the cartridge may be detected electrically, magnetically or optically.

As described above, in the embodiment of the present invention,
The ink jet recording apparatus has a configuration in which a control circuit unit for controlling the cartridge is separated from a cartridge including a head unit having an ink ejection port group for ejecting ink and an ink accommodating unit for accommodating the ink and mounted on a carriage Therefore, it is possible to reduce the size of the head and the carriage as a whole, and it is possible to semi-permanently use the control circuit section that has been discarded when the cartridge is replaced.
The cost of the cartridge can be reduced.
