The present invention reduces a variation in brightness among light emitting portions provided in a plurality of liquid containers to decrease power required to drive the light emitting portions, while allowing the light emitting portions to appropriately function as reporting means. Thus, to illuminate the light emitting portions provided in the plurality of ink tanks, a driving pulse for each of the plurality of light emitting portions is modulated to control rates of a light emission period and a light emission halted period during a unit time. Further, the light emission period of at least one of the plurality of light emitting portions is in the light emission halted period of another at least one of the plurality of light emitting portions.

A liquid container of this invention comprises: a hollow tubular member whose one end installed in the liquid container is connected to the supply port; liquid supply holes formed in the tubular member; and an air introducing port provided at a bottom of the tubular member to introduce air into the tubular member; wherein the liquid in the liquid container is introduced into the tubular member through the liquid supply holes and the liquid thus introduced is supplied from the supply port to another device. As air is introduced from the air introducing port into the tubular member and rises as a bubble in the tubular member, a convection is generated to agitate the liquid inside the tubular member. This agitating action alleviates concentration variations in the liquid in the tubular member.

The invention is to connect a liquid container, having a fluid connecting portion and an information memory medium, to the main body of a recording apparatus without generating stress in both connecting portions. An information memory medium is fixed on the internal wall of a connection aperture of an information memory medium holder, which is contained in a space defined by an information memory medium holder containing portion and a bottom cover. The space is of a size capable of containing the information memory medium holder without contact thereto, and the information memory medium holder can change its position and direction in the space. The changes in the position and direction of the information memory medium holder allow to achieve fluid connection and connection of the information memory medium without generating stress in the connecting portions thereof, even if the fluid connecting portion and the connecting portion for the information memory medium in the main body of the recording apparatus have certain aberration in the relative position and relative direction.

When a package in which a tank 1 is wrapped is opened, caused is an action of reversing vertical positions of an end face of the tank 1 having an ink supply portion 10, and an end face opposite to the foregoing end face. Along with this action, air existing inside the tank 1 ascends, and then is separated by air separating portions. Thus, a coloring material component inside the tank is stirred.

The printing head has connection terminals for performing an electrical connection of signals including drive signals of print elements by contacting connection terminals in on an apparatus side when the head is mounted onto an ink jet printing apparatus. Connections of all terminals can be guaranteed by detecting contacts of a part of terminals. Among the terminals in the head, terminals whose distances from the connection terminals in the printing apparatus become maximum when a deviation occurred in the mounting are used as terminals for contact detection. For example, from among the connection terminals arranged in a planar area, which is rectangular-shaped, terminals positioned in corners are used as the terminals for the contact detection. When the contacts of these terminals are detected, the connections of all the terminals inside the area can be guaranteed.
