Abstract

Abstract An image input device having an original exposing portion and an image sensor portion disposed and an image sensor portion disposed on a common insulating substrate. The original exposing portion is formed by one or more light-emitting elements. The image sensor portion is formed by one or more light-receiving elements individually corresponding to the light-emitting elements and receiving the lights of the light-emitting elements after the exposure of an original and putting out electrical signal levels in accordance with the quantities of received light. This invention further provides an image output and input device which includes in addition to said original exposing portion and said image sensor portion, a thermal head portion formed by one or more heat-generating resistance members which receives the electrical signals from the light-receiving element and generates heat.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 160 words
An image input and output device comprising: an original exposing portion comprising one or more light-emitting elements, an image sensor portion comprising one or more light-receiving elements individually corresponding to said light-emitting elements and receiving the light of said light-emitting elements after the exposure of an original and putting out electrical signal levels in accordance with the quantities of received light, thereby to read the original, and a thermal head portion comprising one or more heat-generating resistance members individually corresponding to said light-receiving elements and receiving the electrical signals from said light-receiving elements and generating heat corresponding to the electrical signal levels, and effecting printing using a thermosensitive transfer medium simultaneously with and independently of reading of the original by said image sensor portions, said original exposing portion and said image sensor portion being disposed on one side surface of a common insulating substrate, and said thermal head portion being disposed on the other surface of said common insulating substrate.
Claim 2
Dependent Claim 160 words
An image input and output device comprising: an original exposing portion comprising one or more light-emitting elements, an image sensor portion comprising one or more light-receiving elements individually corresponding to said light-emitting elements and receiving the light of said light-emitting elements after the exposure of an original and putting out electrical signal levels in accordance with the quantities of received light, thereby to read the original, and a thermal head portion comprising one or more heat-generating resistance members individually corresponding to said light-receiving elements and receiving the electrical signals from said light-receiving elements and generating heat corresponding to the electrical signal levels, and effecting printing using a thermosensitive transfer medium simultaneously with and independently of reading of the original by said image sensor portions, said original exposing portion and said image sensor portion being disposed on one side surface of a common insulating substrate, and said thermal head portion being disposed on the other surface of said common insulating substrate.
Claim 3
Dependent Claim 31 words
An image input and output device according to claim 1, wherein said original exposing portion, said image sensor portion and said thermal head portion are finished through the same manufacturing process.
