* Provided on the European version.
n
Main PCB
This manages all the components including an LCD, motor, key pad, and thermal print
head.
n
Motor
The DC motor is a power source to advance tape. It operates on 9V (unstabilized).
n
Thermal Print Head
This is a thick-film thermal print head which integrates a heat generator (consisting of 64
heating elements vertically aligned) and driver circuitry. When selectively energized by
9V (unstabilized), those heating elements produce characters.
n
LCD
The LCD is 8 characters wide by one row and it has also 11 guidance indicators.
n
Sub PCB
This allows you to use an AC adapter.
