Abstract
A projector and a reflection plate with stripe shaped patterns printed on it are used for projecting the reflection light of the stripe shaped pattern onto a tape. An inspection apparatus for inspecting the crease condition of the tape by analyzing the pitch of the stripe shaped pattern projected onto the tape on a plurality of inspection lines is provided so that the change condition of delicate creases may be detected in a short time.
Claims18
A method of inspecting a tape crease, comprising:
- providing a light source and a reflection plate having a stripe shaped pattern;
- illuminating said reflection plate with said light source to cause light from said reflection plate to be reflected onto the tape in the stripe shaped pattern;
- and
- inspecting the striped shaped pattern reflected onto the tape.
A tape crease inspecting apparatus, comprising:
- means for projecting light and reflecting the light onto a tape in a stripe shaped pattern;
- and
- a means for inspecting the stripe shaped pattern reflected onto the tape on a plurality of inspection lines and determining the pitch of the stripe shaped pattern on the plurality of inspection lines, and for analyzing the pitch of the stripe shaped pattern reflected onto the tape on the plurality of inspection lines.
A tape crease inspecting apparatus, comprising:
- a means for projecting light and reflecting the light onto a tape in a stripe shaped pattern;
- a means for analyzing the pitch of the stripe shaped pattern reflected onto the tape on a plurality of inspection lines and extract from the pitch of the stripe shaped pattern a plurality of characteristic amounts of the stripe shaped pattern;
- and
- a means for discriminating a condition of a crease of the tape onto which the stripe shaped pattern is reflected using fuzzy logic and the plurality of characteristic amounts extracted by said means for analyzing.
