IMAGING DEVICE, COMMUNICATION DEVICE AND CARTRIDGE Russian patent published in 2010 - IPC H01L25/00 

FIELD: physics.

SUBSTANCE: imaging device and communication device include: a data transmission unit, several signal transmission lines, a control unit, a switching unit, a data receiving unit and several signal reception lines, capable of transmitting a data signal from memory of several cartridges to the said data receiving unit. The data signal is transmitted to the said data receiving unit through a signal reception line connected to cartridge memory which can be connected to the said data transmission unit in response to connection of the said data transmission unit with one the said several signal transmission lines through the said switching units. The cartridge used in the imaging device contains: a first contact and a second contact, which can be connected to the communication device through two communication lines, a memory chip which can be connected to the first contact and the second contact.

EFFECT: design of an imaging device which communicates with several cartridges without increasing size of its circuits.
