A conveyor system conveys sheets of different widths in a direction normal to the direction of width with an edge of each sheet held along a reference position. The conveyor system includes a drive roller and a nip roller and conveys the sheet with the nip roller urged toward the drive roller under its gravity and a predetermined urging force. The nip roller is heavier at a part on the side of the reference position than at a part on the side opposite to the reference position and is substantially uniform in weight over a predetermined length between the end on the side of the reference position and a part at a predetermined distance from the end on the side of the reference position, and the predetermined urging force is set stronger on the side opposite to the reference position than on the side of the reference position.
A sheet conveyor system which conveys a plurality of kinds of sheet material, different at least in dimension in a first direction, in a second direction normal to the first direction with an edge of each sheet material extending in the second direction held along a reference position, the sheet conveyor system comprising:

1. Field of the Invention
This invention relates to a sheet conveyor system which conveys a plurality of kinds of sheet material different in width, and more particularly to such a sheet conveyor system which can convey straight the sheet to be conveyed irrespective of width.
2. Description of the Related Art
FIG. 1 is a schematic view showing a radiation image information read-out apparatus provided with a sheet conveyor system in accordance with an embodiment of the present invention,
FIG. 2 is a perspective view showing the two roller pairs employed in the sheet conveyor system,
FIG. 3 is a view taken in the direction of arrow B in FIG. 2,
In FIG. 1, a touch panel 54 which functions as a control panel and a monitor is provided on an upper front portion of a radiation image information read-out apparatus 52, and a cassette loading section 58 in which a cassette 56 is removably loaded is provided below the touch panel 54. A sheet separator 60 is formed in the cassette loading section 58, and an erasing section 64 and a read-out section 66 are connected downstream of the sheet separator 60 by way of a sheet conveyor system 50. The erasing section 64 comprises a plurality of erasing light sources 70 arranged along the sheet conveyor system 50.
The read-out section 66 comprises a sub-scanning system 78 which conveys a stimulable phosphor sheet 40 taken out from the cassette 56 in a sub-scanning direction (the direction of arrow A) by two roller pairs 74 and 76, an optical system 80 which causes a laser beam L to scan the stimulable phosphor sheet 40 in a main scanning direction substantially normal to the sub-scanning direction while it is being conveyed in the sub-scanning direction, and a light condensing system 82 which photoelectrically reads the stimulated emission emitted from the stimulable phosphor sheet 40 upon exposure to the laser beam L.
The cassette 56 comprises a cassette body 84 and a lid 88 which closes and opens the opening 86 of the cassette body 84. The cassette loading section 58 is provided with a lid opening means (not shown) for opening and closing the lid 88.
