3-3. Detecting Mechanism
<Selecting between Tax/EURO exchange functions> Either of the Tax and Euro exchange functions can be selected by changing the signal with the jumper cables on the KEY PWB. <Backup of Tax/EURO exchange functions> This machine is an AC/DC type which retains Tax data (tax rates and others) and EURO exchange data in memory only when power is supplied from the battery or an AC adapter. Therefore, data in memory cannot be retained if the AC adapter is disconnected. (Data in memory cannot also be retained when batteries are changed.) The detector is of mechanical contact type and consists of the code plate to output the character position detection signal to correspond to each character on the character belt, sensor gear unit to output the standard position signal, and fixed contact-piece unit.
