Claims
- 1. A sheet cassette for use in a sheet feeder apparatus having a separation means for separating a sheet cover form a flange portion and an attachment means for attaching the sheet cover to the flange portion, comprising:
- a container composed of a first material, said material capable of accommodating a plurality of sheet materials and having a flange portion;
- an adhesive layer positioned on and affixed to said flange portion; and
- a sheet cover bonded on said adhesive layer for covering an opening of said sheet cassette, said cover composed of a second material, said adhesive layer bonding to the first material with a force greater than to the second material, enabling said sheet cover to be repeatedly separated from, or attached to, said container for opening or closing said opening.
- 2. The sheet cassette according to claim 1, wherein said sheet cover can prevent light form entering said container.
- 3. The sheet cassette of claim 1 further including a bar code applied to a surface of the container to identify the kind and size of sheet materials.
- 4. In a sheet cassette for use i a sheet feeder for an image forming apparatus having a take-up member for winding and rewinding a cover member on the sheet cassette, the improvement comprising:
- a container capable of accommodating a plurality of sheet materials and having a flange portion;
- a first adhesive layer formed on the flange portion and having a predetermined adhesive characteristic relative to an integral strength of the cover member to permit a portion of the cover member to be repeatedly separated form or applied to the adhesive layer for opening or closing the container, and
- a leading end portion of the cover member protruding outward from the flange portion along substantially the entire width of the cover member and having a second adhesive layer bonded along substantially the entire width of the leading end portion, said second adhesive layer adhering to the take-up member when the take-up member is winding or rewinding the cover member.
- 5. The sheet cassette of claim 4 wherein said sheet cover has a leading edge protruding outwards to be cantilevered from said container and the cantilevered portion is coated on at least one side with an adhesive layer.
- 6. The sheet cassette of claim 4 wherein the cover member is an opaque plastic sheet.
- 7. The sheet cassette of claim 4 wherein the container further includes a bar code applied to a surface of the container to identify the kind and size of sheet materials.
- 8. The sheet cassette of claim 4 wherein the second adhesive layer is offset form and parallel to an edge of the flange.
- 9. A sheet cassette comprising:
- a container capable of accommodating a plurality of sheet materials and having a flange portion, with
- double sided adhesive tape positioned on said flange portion; and
- a sheet cover bonded on said adhesive layer for covering an opening of said sheet cassette, the adhesive layer having a predetermined adhesive characteristic relative to an integral strength of the cover to permit a portion of said sheet cover to be repeatedly separated form or applied to said adhesive layer for opening or closing said opening.
- 10. A sheet cassette comprising:
- a container capable of accommodating a plurality of sheet materials and having a flange portion;
- an adhesive layer positioned on said flange portion;
- a sheet cover bonded on said adhesive layer for covering an opening of said sheet cassette, the adhesive layer having a predetermined adhesive characteristic relative to an integral strength of the cover to permit a portion of said sheet cover to be repeatedly separated from or applied to said adhesive layer for opening or closing said opening, and
- a plurality of extendable bellows members on the container capable of being extended to raise one end of the sheet materials for dispensing from the container.
- 11. In a sheet cassette for use in a sheet feed for an image forming apparatus having a take-up member for winding and rewinding a cover member on the sheet cassette, the improvement comprising:
- a container capable of accommodating a plurality of sheet materials and having a flange portion;
- a first adhesive layer comprising double-sided adhesive tape positioned on the flange portion and having a predetermined adhesive characteristic relative to an integral strength of the cover member to permit a portion of the cover member to be repeatedly separated from or applied to the adhesive layer for opening or closing the container, and
- a leading end portion of the cover member protruding outward from the flange portion and having a second adhesive layer bonded on the leading end portion in a configuration suitable for adhering to the take-up member.
- 12. In a sheet cassette for use in a sheet feeder for an image forming apparatus having a take-up member for winding and rewinding a cover member on the sheet cassette, the improvement comprising:
- a container capable of accommodating a plurality of sheet materials, the container having a flange portion, and a bottom provided with a plurality of flexible extension members for lifting the sheet materials;
- a first adhesive layer formed on the flange portion and having a predetermined adhesive characteristic relative to an integral strength of the cover member to permit a portion of the cover member to be repeatedly separated from or applied to the adhesive layer for opening or closing the container, and
- a leading end portion of the cover member protruding outward from the flange portion and having a second adhesive layer bonded on the leading end portion in a configuration suitable for adhering to the take-up member.
- 13. The sheet cassette of claim 12 further including a support member positioned above the extension members and below the sheet material.
- 14. The sheet cassette of claim 12 wherein the flexible extension members are light shielding bellows.
- 15. A sheet cassette comprising:
- a container composed of a first material, said material capable of accommodating a plurality of sheet materials and having a flange portion;
- an adhesive layer positioned on said flange portion; and
- a sheet cover bonded on said adhesive layer for covering an opening of said sheet cassette, said cover composed of a second material, said adhesive layer bonding t the first material with a force greater than to the second material, enabling said sheet cover to be repeatedly separated from, or attached to, said container for opening or closing said opening, wherein said sheet cover has a leading end portion protruding outward from said flange portion along substantially the entire width of said sheet cover and an adhesive layer bonded on said leading end portion along substantially the entire width of said leading end portion, said adhesive layer being adapted to be further bonded to a member for winding said sheet cover.
