Abstract
A guide pin for use in a tape cassette. The guide pin includes a cylinder having a tape contact section, a press fit section and a slot extending through the tape contact and press fit sections. Upon compression of the press fit section, the press fit section may be inserted into an aperture of the tape cassette. After insertion, the guide pin is released and the resiliency of the press fit section moves the press fit section against the inner walls of the aperture to secure the guide pin to the tape cassette.
Claims13
A guide pin for a tape cassette, said tape cassette having an aperture for receiving said guide pin, said guide pin comprising:
- a cylinder having first and second ends and an interior hole extending between said first end and said second end to form a hollow cylinder having a cylinder walk said wall having an outer surface;
- first and second flanges extending from said outer surface to divide said outer surface into a tape contact section located between said first flange and said second flange and a press fit section located adjacent said second flange on the opposite side thereof from said first flange;
- and
- a slot extending through said wall and between said first end and said second end to form, in a first position, opposed resilient members in said press fit section, wherein upon insertion of said press fit section into said aperture, said opposed resilient members are compressed to a second position and are biased to move toward said first position thus forming a press fit in said aperture for securing said guide pin in said aperture.
A tape cassette, comprising:
- a cassette casing having at least one aperture;
- a plurality of reels for advancing tape between said reels, said reels being rotatably mounted within said casing;
- at least one guide pin positioned for guiding said tape to said reels, said guide pin having:
- a cylinder including first and second ends and an interior hole extending between said first end and said second end to form a hollow cylinder having a cylinder wall, said wall having an outer surface;
- first and second flanges extending from said outer surface to divide said outer surface into a tape contact section located between said first flange and said second flange and a press fit section located adjacent said second flange on the opposite side thereof from said first flange;
- and
- a slot extending through said wall and between said first end and said second end to form, in a first position, opposed resilient members having a frusto conical shape in said press fit section, wherein upon insertion of said press fit section into said aperture, said opposed resilient members are compressed to a second position and are biased to move toward said first position thus forming a press fit in said aperture for securing said guide pin in said aperture.
A tape cassette, comprising:
- a pair of reels mounted side by side, on which magnetic tape is wound;
- a cassette casing for rotatably enclosing said pair of reels therein;
- at least one tape guide pin press-fitted through the wall of said casing, said guide pin having a pair of flange sections for defining a tape path for tape travel between the pair of reels, a contact section formed between said pair of flange sections on which a tape contacts said contact section around a wrap angle, said guide pin having a press-fit section press-fitted into a hole in said casing, said guide pin having a hollow extending along a center of said guide pin;
- said guide pin further including an opening extending to said hollow and perpendicularly through said flange section, said contact section and said press-fit section of said guide pin at a location outside of said wrap angle, wherein a spring back force of said press-fit section secures a connection between said guide pin and said casing.
