Abstract
Abstract A card type image reader comprises a rectangular card base and a reinforcing member provided on one side of the card base. A photodetector array in a straight line is provided on one end portion of the reinforcing member and the card base holds control circuit means and memory means. The control circuit means reads information of an original through the photodetector array in synchronization with a clock signal and stores the read information into the memory means.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
164 words
A card type image reader to be moved on a surface of an original, comprising: a card base, means for relieving bending stresses at a portion of a periphery of said card base, said relieving means including a reinforcing member provided on the portion of the periphery of said base, said card base having an area spaced away from said reinforcing member which is more easily bendable than is said portion of said periphery of the card base due to said reinforcing member being on said portion, a linear photodetector array formed on one end portion of said reinforcing member, control circuit means held in said card base, said control circuit means including clock means for generating a clock signal and reading information of said original by repeating scanning from one end to the other end of said linear photodetector array in synchronization with said clock signal, and memory means held in said card base, for storing information read by said control circuit means.
Claim 2
Dependent Claim
164 words
A card type image reader to be moved on a surface of an original, comprising: a card base, means for relieving bending stresses at a portion of a periphery of said card base, said relieving means including a reinforcing member provided on the portion of the periphery of said base, said card base having an area spaced away from said reinforcing member which is more easily bendable than is said portion of said periphery of the card base due to said reinforcing member being on said portion, a linear photodetector array formed on one end portion of said reinforcing member, control circuit means held in said card base, said control circuit means including clock means for generating a clock signal and reading information of said original by repeating scanning from one end to the other end of said linear photodetector array in synchronization with said clock signal, and memory means held in said card base, for storing information read by said control circuit means.
Claim 3
Dependent Claim
26 words
A card type image reader in accordance with claim 1, wherein said card base further holds an operation switch and a battery as a power supply.
Claim 4
Dependent Claim
41 words
A card type image reader in accordance with claim 1, wherein said card base further holds input/output terminals for an external apparatus and the information stored in said memory means is read out by the external apparatus through said input/output terminals.
Claim 5
Dependent Claim
27 words
A card type image reader in accordance with claim 1, wherein said card base further holds a display near said reinforcing member, for displaying said read information.
Claim 6
Dependent Claim
30 words
A card type image reader in accordance with claim 1, wherein the end portion of said reinforcing member where said photodetector array is provided has a wedge form in cross-section.
Claim 7
Dependent Claim
30 words
A card type image reader in accordance with claim 1, wherein the end portion of said reinforcing member where said photodetector array is provided has a semicircular form in cross-section.
Claim 8
Dependent Claim
107 words
A card type image reader to be moved on a surface of an original, comprising: a card base which has a peripheral portion and an area away from said peripheral portion that is bendable; photodetector means; reading means for reading information of the original through said photodetector means, said reading means being on said card base; and means for relieving bending stresses at said peripheral portion of said card base so as to avoid propagation of the bending stresses to said photodetector means, said relieving means including a reinforcing member on the peripheral portion of said card base, said photodetector means being arranged on said reinforcing member.
Claim 9
Dependent Claim
107 words
A card type image reader to be moved on a surface of an original, comprising: a card base which has a peripheral portion and an area away from said peripheral portion that is bendable; photodetector means; reading means for reading information of the original through said photodetector means, said reading means being on said card base; and means for relieving bending stresses at said peripheral portion of said card base so as to avoid propagation of the bending stresses to said photodetector means, said relieving means including a reinforcing member on the peripheral portion of said card base, said photodetector means being arranged on said reinforcing member.
Claim 10
Dependent Claim
64 words
A card type image reader in accordance with claim 7, wherein said photodetector means forms a linear array of photodetectors, said reading means including means for scanning across said linear array from one end of said linear array to another end of said linear array so as to read the information on the original and for storing the information read by said scanning means.
Claim 11
Dependent Claim
61 words
A card type image reader in accordance with claim 8, wherein said reading means includes clock means for generating clock signals and means for synchronizing said scanning means to repeatedly scan across said linear array from said one end to said another end of said linear array in synchronism with said clock signals to thereby read the information on the original.
