Abstract
A sheet feed device applicable to a recorder such as an ink jet printer or a thermal printer has feed rollers mounted on the same shaft in a spaced relationship and platen blocks mounted in spaces between the feed rollers. A sheet fed along the feed rollers is conveyed to the platen blocks by a feed force of the feed rollers.
Claims23
A sheet feed device for a recording apparatus, comprising:
- a plurality of rotatable members arranged in spaced relation along a width of a sheet feed path for feeding a sheet in a feeding direction;
- and
- a plurality of guide members separated and disposed between said rotatable members, each said guide member having first and second guide surfaces for guiding the sheet, wherein each said first guide surface is disposed to substantially coincide with a predetermined extent of the peripheries of said rotatable members with respect to the sheet feed path and each said second guide surface extends continuously from the corresponding said first guide surface downstream of said first guide surface with respect to the sheet feeding direction to provide a recording area where the recording apparatus can record on the sheet supported by said second guide surfaces.
