摘要:
An image sensor device having a plurality of sensor elements connected in a matrix is driven by sequentially applying successive driving pulses, wherein a leading edge of a driving pulse coincides with a trailing edge of a preceding driving pulse and the slew rate at the leading edge is equal to the slew rate at the trailing edge.
摘要:
A contact type image sensor including a plurality of photodiodes for converting a light signal into an electric signal according to the intensity of the light and a plurality of blocking diodes, arranged in either a back-to-back or a front-to-front connection with the photodiodes, for functioning as switching elements to have the information stored on the photodiodes read out, and adapted to be driven by a matrix drive system. For a back-to-back connection of the blocking diodes and photodiodes, a control circuit maintains the potential difference between cathodes of the photodiodes at zero volts at all times. Similarly, for a front-to-front connection of the blocking diodes and photodiodes, a control/drive circuit maintains the potential difference between the anodes of the photodiodes at zero volts at all times. Since the potential difference between the cathodes (for the back-to-back connection) or anodes (for the front-to-front connection) of all of the photodiodes is always maintained at zero volts, crosstalk at crossover portions between output lines connected to the photodiodes is reduced.
摘要:
A complete close-contact type image sensor which comes into contact with an original and reads information from the original and which includes a sensor element for photoelectro conversion of a light signal reflected from the original and electronic parts such as a driven unit for driving the sensor element and taking out an electric signal stored in the sensor element, the image sensor being characterized in that the electronic parts such as the driving unit are disposed inside a plane including the surface of contact with the original. According to the above construction of the present invention, since the electronic parts, including the driving unit, are disposed inside the plane which includes the surface of contact with the original, the path of transfer of the original can be made rectilinear to stabilize the feed of the original without enlarging the gap between the sensor element and the original.
摘要:
A complete-contact type image sensor includes matrix-driven sensor elements arranged on a light transmitting substrate. Both input contact members connected with the sensor elements at their input side and output contact members connected with the sensor elements at their output side are formed at one same side on the light transmitting substrate. By virtue of this arrangement, the sensor elements and an original are brought into close contact, thereby improving the MTF (Modulation Transfer Function) and reducing the width of the light transmitting substrate.
