An ink tank detachably mounted on a printer includes a non-volatile memory and a LED for executing a process in response to a condition of the tank such as ink residual quantity by transmitting information stored in the memory to a printer, and informing the condition of the ink by use of the LED. Further, the content stored in the memory is prevented from being destroyed, and the LED can perform light emission until immediately before detachment and thus contribute to improvement in workability of a user. A volatile memory element is provided in addition to the non-volatile memory. When a user can detach the tank, condition information on the ink tank retained by the non-volatile memory is transferred to the volatile memory in advance. When it is possible to detach the tank, control for turning the LED on and off is achieved by accessing only to the volatile memory.

Disclosed is a printing head having connection terminals for performing an electrical connection of signals including drive signals of print elements by contacting connection terminals in an apparatus side when the head is mounted onto an ink jet printing apparatus. It is made to guarantee connections of all terminals 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.

摘要:
The power consumption of the entire recording apparatus is decreased in the structure that the recording element and the light emitting portion are provided on the ink tank, processes according to the amount of the residual ink is performed by communicating information stored in the recording element to the main body of the recording apparatus, and the condition of the ink tank can be informed by emitting light. The ink tank comprises the recording element, the light emitting portion, and the controlling portion driving the the recording element and the light emitting portion at the appropriate timing, and further comprises the voltage level chanigng menas for supplying the appropriate voltage to each thereof. Relatively low voltage is constantly supplied to the controlling portion, thereby driving the recording element and the light emitting portion at the appropriate timing. Accordingly, appropriate processings can be divided according to necessary events during the series of processings for the recording apparatus, thereby realizing the power saving effect.
