Abstract: In an ink tank, there are provided a main ink chamber containing a capillary vessel member, and an intermediate ink chamber. When the ink is consumed, the ink held by capillary force of a capillary vessel member is supplied via a communication port from a joint port. The same amount of air as the amount of the consumed ink is conducted from the atmospheric communication port into the main ink chamber. The conducted air is supplied via a groove formed in a lid to an upper surface of the capillary vessel member. As a result, the air is entered into the capillary vessel member under better condition. In a plane portion of the lid, the ink is in contact with only the capillary vessel member, and the ink remaining this portion is reduced. Thus, the ink using efficiency is increased.

Abstract: An elastic jointing member 22 with an umbrella-like portion with an opening and a flat part is provided in a jointing portion between a recording head 21 and an ink tank 1. When the ink tank 1 is attached to the recording head 21, the umbrella-like portion of the elastic jointing member 22 is pressed against the ink tank and elastically deformed inward. As a result, an ink passage is formed which is airtightly sealed. In the process of pressing the umbrella-like portion against the ink tank, the umbrella-like portion comes in contact with the flat part, to thereby prevent air from staying in the ink passage. Protrusions or grooves may be provided between the umbrella-like portion and the flat part. With the protrusions or the groove, the umbrella-like portion is not glued to the flat part.

Abstract: An ink printer designed to make users free from any danger when an inktank is replaced and to prevent ink from leaking out when the inktank is detached. The joint part of an inktank is pressed against the ink guide of a print head to couple the inktank and the print head together, so that ink is supplied from the inktank to the print head. The joint part is supplied with a porous material. When the inktank is attached, the porous material is compressed and contained in the joint part. When the inktank is detached from the print head, the volume of the porous material increases thereby raising its porosity. The ink remaining in the joint part is absorbed by the porous material whose porosity has been raised, so that ink is prevented from flowing out in the vicinity of the joint part when the inktank is removed.

Abstract: A main ink chamber for housing a capillary member and an intermediate ink chamber are provided, between which a first meniscus formation member is disposed. An ink guide member is in contact with the bottom face of the first meniscus formation member for supplying ink to the first meniscus formation member. The ink guide member is held by ink guide member retainers extending toward the ink guide member from a wall of a communication hole and is kept in contact with the first meniscus formation member. A larger number of the ink guide member retainers are placed on a side of the communication hole closer to a joint port than are placed on a side of the communication hole closer to the intermediate ink chamber. The placement of the ink guide member retainers guides bubbles entering the communication hole through the first meniscus formation member to the intermediate ink chamber to prevent bubbles entering the joint port and reaching the print head.

Abstract: In an ink tank, a main ink chamber is contiguous to a sub ink chamber containing an absorption member, and an air communication hole is formed on the top of the sub ink chamber. The absorption member holds ink pressure constant by capillary attraction of the absorption member. First, ink in the sub ink chamber is consumed with consumption of ink. When ink is consumed in a predetermined amount, air passes through the absorption member and a meniscus forming portion to form bubbles, which then move to the main ink chamber. Ink pressure is held constant by surface tension of the meniscus forming portion. Even if ink remains in a small amount, the ink leading portion makes the meniscus forming portion wet for holding ink pressure.

Abstract: An ink supply passage 16 has a large cross-sectional area and ink tanks 6 are connected to the top of the ink supply passage 16. An ink supply passage 17 is a flow passage shaped like a semicylinder and has a cross-sectional area equal to or smaller than the cross-sectional area of the ink supply passage 16. Even if bubbles are mixed into the ink supply passage 17, they adhere to the upper portion of the flow passage 17 and do not flow into lower corners, so that a flow passage can be provided and the ink flow is not hindered. Since an ink supply passage 19 connected to a head chip 4 has a small diameter, bubbles mixed into the ink supply passage 19 can be removed by maintenance for sucking ink forcibly. Bubbles mixed upstream are not transported to the ink supply passage 19 because of the flow rate difference caused by the cross-sectional area difference.

Abstract: A scanner for reading an object having a width larger than that of the distal end portion of a scanner main body, has an exit opening for outputting a light beam formed at the distal end portion of the scanner main body. An LED for generating a light beam, and a solid-state image pickup element for receiving the light beam which is reflected by the code, are arranged in the scanner main body. A gap portion for increasing the irradiation width of the light beam to be larger than the width of the distal end portion of the scanner main body is formed at the distal end portion of the scanner main body. Therefore, when a code is read by bringing the scanner main body close to or into contact with the code, the gap portion increases the width of the light beam to be larger than that of the distal end portion of the scanner main body, and therefore, a code having a width larger than the width of the distal end portion of the scanner main body can be read.

Abstract: A child seat capable of easily adjusting its reclining angle. The child seat is placed on a vehicle seat, and the tongue of a seat-side belt and the buckle of a belt are latched to each other. Then, the dial is turned to wind the belt to fix the child seat to the vehicle seat. To adjust the reclining angle, a lock-releasing lever is pulled to pull out seat-fixing pins from pin through holes and to pivot an arm portion by a link bar so as to release the locking of the winder.

Abstract: A main ink chamber with a through-hole contains a capillary member. An intermediate ink chamber is provided on the side wall of the main ink chamber. A path communicatively interconnects the main ink chamber and the intermediate ink chamber. A second meniscus forming member is disposed in a joint port, to thereby prevent ink leakage. In a print mode, ink flows from the main ink chamber to the joint port, through a meniscus forming member that is disposed in the through-hole. Air bubbles mingled into the ink move along the slanting upper wall of the path by their buoyant force, and are accumulatively stored in the upper part of the intermediate ink chamber. When ink is reduced to zero in the main ink chamber, air bubbles are introduced into the intermediate ink chamber through the meniscus forming member. As a result, the liquid level of the intermediate ink chamber is quickly reduced, thereby indicating a state that ink is used up.
