ていた。The conventional thermal recording head mentioned above has control signal lines such as the recording ground, clock, latch, strobe, etc.
Because 5V and ground lines were provided for each drive IC, a significantly large number of connection terminals were required for the entire head, and these were connected to the external circuit by pressure contact using a flexible cable, which deteriorated the reliability of the connection. It was becoming a big problem.

The purpose of the present invention is to provide a thermal recording head in which the terminal density of +5V power supply and logic ground lines (latches and strobes), +5V power supply and logic ground lines is reduced, the number of connection terminals with flexible cables is reduced, and connection reliability is greatly improved.

By providing a common terminal for each flexible cable, the number of terminals connected to the flexible cable can be halved, and the terminal size can be increased, which has the effect of significantly improving the reliability of the connection. For example, with an A4 size head of 8 dots/mm,
For a 32-bit IC, a density of 6 terminals per 8 mm is sufficient, and compared to conventional beds, connection troubles can be completely eliminated.
