Abstract
Abstract An image reading device comprises: a frame; a reading unit provided with a line sensor for reading a text image; a guide member fixed to the frame for supporting the reading unit such that the reading unit is free to slide in a predetermined direction; and a stay fixed to the frame. A screwhole is formed at a predetermined position in the reading unit, a first throughhole is formed in the frame coaxially with the screwhole, and a second throughhole is formed in the stay coaxially with the screwhole and the first throughout. Further, an elastic member having a third throughhole engages with the first throughhole in the frame, and a holding member is provided comprising a grip of large diameter and a screw of small diameter. The reading unit is fixed, when the image reading device is transported, by screwing the screw into the screwhole of the reading unit through the second throughhole of the stay and through the third throughhole of the elastic member.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
171 words
An image device comprising: a frame; a reading unit provided with a line sensor for reading a text image; a guide member, fixed to said frame, for supporting said reading unit such that said reading unit is free to slide in a predetermined direction; and a stay fixed to said frame, wherein a screwhole is formed at a predetermined position in said reading unit, a first throughole is formed in said frame coaxially with said screwhole, and a second throughhole is formed in said stay, coaxially with both said screwhole and said first throughhole, and wherein an elastic member, having a third throughhole, is engaged with said first throughhole in said frame, and a holding member is provided including a grip of large diameter and a screw of small diameter, such that said reading unit is fixed when the image reading device is transported by screwing said screw into said screwhole of said reading unit through said second throughhole of said stay and through said third throughhole of said elastic member.
Claim 2
Dependent Claim
171 words
An image device comprising: a frame; a reading unit provided with a line sensor for reading a text image; a guide member, fixed to said frame, for supporting said reading unit such that said reading unit is free to slide in a predetermined direction; and a stay fixed to said frame, wherein a screwhole is formed at a predetermined position in said reading unit, a first throughole is formed in said frame coaxially with said screwhole, and a second throughhole is formed in said stay, coaxially with both said screwhole and said first throughhole, and wherein an elastic member, having a third throughhole, is engaged with said first throughhole in said frame, and a holding member is provided including a grip of large diameter and a screw of small diameter, such that said reading unit is fixed when the image reading device is transported by screwing said screw into said screwhole of said reading unit through said second throughhole of said stay and through said third throughhole of said elastic member.
Claim 3
Dependent Claim
68 words
An image reading device as defined in claim 1, further comprising: a compression spring provided on the outer side of said stay, for pushing said holding member towards the outside of said image reading device; and a clip provided on said holding member, for contacting with the inner side of said stay when the screwhole of said reading unit and the screw of said holding member are disengaged.
Claim 4
Dependent Claim
38 words
An image reading device as defined in claim 1, wherein said screwhole of said reading unit is formed on a line passing through the center of gravity of said reading unit, or in the vicinity of said line.
Claim 5
Dependent Claim
68 words
An image reading device as defined in claim 1, further comprising: a motor providing a drive force for driving said reading unit along said guide member; and a circuit board for processing a signal output by said line sensor, wherein said motor and said circuit board are installed in positions on the opposite side of the position at which said reading unit is fixed by said holding member.
Claim 6
Dependent Claim
193 words
An image reading device comprising: a frame; a reading unit including a line sensor for reading a text image; a guide member, fixed to said frame, for supporting said reading unit such that said reading unit is free to slide in a predetermined direction; and a stay fixed to said frame, wherein a projection is provided at a predetermined position on said reading unit, a first throughhole is formed in said frame, and a second throughhole is formed in said stay coaxially with said first throughhole, wherein said image reading device further includes, a holding member passing through said first throughhole in said frame and said second throughhole in said stay, said holding member including a hook at an end and a grip on the outer side of said stay, said hook being rotated so as to engage with said projection by rotating said grip when said image reading device is transported, a compression spring provided on the outer side of said stay, for pushing said holding member towards the outside of said image reading device, and a clip provided on said holding member, for contacting with the inner side of said stay.
Claim 7
Dependent Claim
193 words
An image reading device comprising: a frame; a reading unit including a line sensor for reading a text image; a guide member, fixed to said frame, for supporting said reading unit such that said reading unit is free to slide in a predetermined direction; and a stay fixed to said frame, wherein a projection is provided at a predetermined position on said reading unit, a first throughhole is formed in said frame, and a second throughhole is formed in said stay coaxially with said first throughhole, wherein said image reading device further includes, a holding member passing through said first throughhole in said frame and said second throughhole in said stay, said holding member including a hook at an end and a grip on the outer side of said stay, said hook being rotated so as to engage with said projection by rotating said grip when said image reading device is transported, a compression spring provided on the outer side of said stay, for pushing said holding member towards the outside of said image reading device, and a clip provided on said holding member, for contacting with the inner side of said stay.
Claim 8
Dependent Claim
68 words
