Abstract

Abstract A tape cassette which is adapted to embody a number of bit patterns in its main body for representing cassette information including tape type information in the cassette. An original pattern to embody a bit pattern is a hole perforated in the wall of the cassette with a block member to close the opening of the hole, and by selective removal of the block member a bit pattern is obtained. For the purpose of smooth and correct punch out of the block member from the main body, a notch (32) is provided through the peripheral of the block member on a selected surface of the connect member corresponding to the punching direction.

Claims Analysis

Total Claims: 7

Claim 1

Independent Claim 167 words

A tape cassette adapted to embody a binary code representing cassette information in the main body thereof, the tape cassette comprising: a path perforated through an outer wall of the main body of the tape cassette for allowing a search pin of a detector in a deck to pass therethrough, the path having an opening on a surface of the outer wall; a block member for blocking the opening; and means for bridging a gap between the periphery of the block member and the main body to connect the both at least at one bridging portion, the bridging means comprising a notched zone provided with a notch on a surface of bridging means along the periphery of the block member for concentrating stress therealong when a punching force is exerted onto the block member in an exerting direction thereby breaking the block member from the main body to expose the opening, whereby a bit pattern is embodied by selectively applying the punching force onto the block member.

Claim 2

Dependent Claim 35 words

The tape cassette of claim 1, wherein the bridging means is provided with the notch on the inner surface thereof and the exerting direction is from the inside to the outside of the tape cassette.

Claim 3

Dependent Claim 32 words

The tape cassette of claim 1, wherein the bridging means is provided with the notch on the outer surface and connects the block member to the main body at two connecting portions.

Claim 4

Dependent Claim 45 words

The tape cassette of claim 1, wherein the bridging means is provided with the notch on each of the inner and outer surfaces and the stress is concentrated by the punching force in both directions between the inside and the outside of the cassette case.

Claim 5

Dependent Claim 16 words

The tape cassette of clain 4, wherein the bridging means bridges all area of the gap.

Claim 6

Dependent Claim 14 words

The tape cassette of claim 5, further providing a standing wall surrounding the opening.

Claim 7

Dependent Claim 18 words

The tape cassette of claim 1, further comprising means for guiding a tool to separate the block member.
