Abstract
A method of making a casing of an image sensor is provided. The method includes the steps of preparing the casing, and applying a static electricity preventive to the casing. The casing is formed with a light passage configured to conduct light emitted from a light source. The static electricity preventive is applied to the inner surfaces of the casing defining the light passage. While the application of the preventive is performed, flashes formed at the light passage are removed.
Claims10
A method of making a casing of an image sensor comprising the steps of:
- preparing a casing having inner surfaces;
- and
- applying a static electricity preventive to the inner surfaces of the casing for preventing the inner surfaces of the casing from electrostatically attracting particles;
- wherein the static electricity preventive comprises a surface-active agent.
A casing of an image sensor comprising:
- a light passage;
- and
- inner surfaces defining the light passage;
- wherein said inner surfaces are coated with a static electricity preventive for preventing the inner surfaces from electrostatically attracting particles;
- and
- wherein the static electricity preventive comprises a surface-active agent.
An image sensor comprising:
- a light source for illuminating an image-carrying document to be read;
- and
- a resin casing supporting the light source and provided with a light passage defined by inner surfaces of the casing;
- wherein the inner surfaces are coated with a static electricity preventive for preventing the inner surfaces from electrostatically attracting particles;
- and
- wherein the static electricity preventive comprises a surface-active agent.
