Title:
PRINTER
Document Type and Number:
WIPO Patent Application WO/2006/025575
Kind Code:
A1
Abstract:
A printer (20) is provided with a contact detecting terminal (101) which is brought into contact with a detecting terminal (116) of an ink cartridge (70) when the ink cartridge (70) is loaded; a cartridge detecting circuit (M10a) which detects whether there is a contact between the detecting terminal (116) and the contact detecting terminal (101); a sensor terminal (104) for outputting a high voltage; and a sensor driving circuit (M20) for controlling the voltage outputted from the sensor terminal (104). The cartridge detecting circuit (M10a) also has a function of a short-circuit detecting means for detecting a short-circuit between the contact detecting terminal (101) and the sensor terminal (104). In the case where a short-circuit is detected, the sensor driving circuit (M20) blocks or reduces the voltage outputted from the sensor terminal (104).
