摘要： A contact image sensor has a plurality of sensor elements on an insulating substrate, the sensor elements having electrodes as common electrodes and other electrodes as individual electrodes. The contact image sensor is manufactured by extending the common electrodes and the individual electrodes out of a document passage region, and forming short-circuiting patterns which electrically connect the common electrodes and the individual electrodes outside of the document passage region through pads which connect ICs for energizing the contact image sensor. After the ICs are connected to the pads, the insulating substrate is cut along the short-circuiting patterns to break the electrical connection between the common electrodes and the individual electrodes.

摘要： A potential across an output terminal (OUT) is applied to a node N2 through a transistor (Tr66) even when a potential across a node N1 is higher than a power source voltage Vdd due to a bootstrap effect. Accordingly, the potentials between the drain and the source electrodes are not higher than the power source voltage Vdd for both a transistor (Tr62) and the transistor (Tr66). This allows circuit designing without setting the withstand voltage for the transistor over the power source voltage Vdd.
摘要翻译：即使跨越节点N1的电位高于由于自举效应引起的电源电压Vdd，跨输出端子（OUT）的电位也通过晶体管（Tr66）施加到节点N2。因此，漏极和源电极之间的电位不高于晶体管（Tr62）和晶体管（Tr66）两者的电源电压Vdd。这允许电路设计，而不设置晶体管的耐压在电源电压Vdd上。
