Claims7
A recording apparatus for recording with a recording head on a recording medium conveyed by a roller, said apparatus comprising:
- a plurality of roller holders provided adjacent to each other along a direction across a conveyance direction of the recording medium and having a holding portion for holding said roller;
- an optical detecting element provided in the vicinity of a space in the recording apparatus where said recording head records on the recording medium to optically detect a desired information;
- and
- a light-shielding construction for preventing an external light from entering into an interior of the recording apparatus and from reaching said optical detecting element through and between adjacent roller holders, said light shielding construction being a light shielding surface provided on at least one wall surface of adjacent said roller holders opposed to each other to shield a route of said external light toward said optical detecting element.
