Claim 3

A tape cassette as claimed in claim 1, wherein the webs are provided with locating faces for the correct positioning on the relevant housing part of the cassette.

Claim 4

A tape cassette according to claim 1, wherein the recesses are grooves corresponding to the webs and substantially running in parallel to the front face of the cassette.

Claim 5

A tape cassette as claimed in claim 1, wherein the housing separator member has recesses for the webs.

Claim 6

A tape cassette as claimed in claim 1, wherein the webs are narrow and arranged at a distance from one another and delimit a hole.

Claim 7

A tape cassette as claimed in claim 1, wherein the housing separator member has a protrusion, the shape of which corresponds to the hole, and which has fixing edges delimiting said protrusion on two sides.

Claim 8

A tape cassette as claimed in claim 1, wherein each of said at least two transparent members is provided with an edge portion bent upwards at 90° and forms part of the side wall of the cassette housing.

Claim 9

A tape cassette as claimed in claim 1, wherein the webs together with the at least two transparent members are an injection molding and a gate mark is located on one of the webs.

Claim 10

A tape cassette, especially a magnetic tape cassette, comprising a cassette housing having upper and lower parts and at least one hub or reel contained therein, and windows which are formed by apertures in at least one of said parts of the housing and transparent members covering the said apertures, wherein said cassette comprises at least two windows each covered by one of said transparent members, a common carrier carrying said at least two transparent members adjacent opposite ends of said carrier, and a housing separator member disposed in said housing part between said windows, said common carrier consisting of webs which connect the said at least two transparent members, and wherein the at least one housing part, in which the windows are formed, is provided at its inner surface with recesses for the correct positioning of said webs and said transparent members, and wherein faces, pointing into the interior of the cassette, of said transparent members, protrude relative to the corresponding housing inner wall and form guide faces at least for the tape roll(s).

Claim 11

A tape cassette, especially a magnetic tape cassette, comprising a cassette housing having upper and lower parts and at least one hub or reel contained therein, and windows which are formed by apertures in at least one of said parts of the housing and transparent members covering the said apertures, wherein said cassette comprises at least two windows each covered by one of said transparent members, a common carrier carrying said at least two transparent members adjacent opposite ends of said carrier, and a housing separator member disposed in said housing part between said windows, said common carrier consisting of webs which connect the said at least two transparent members, and wherein the at least one housing part, in which the windows are formed, is provided at its inner surface with recesses for the correct positioning of said webs and said transparent members, and wherein faces, pointing into the interior of the cassette, of said transparent members, protrude relative to the corresponding housing inner wall and form guide faces at least for the tape roll(s).

Claim 12

A tape cassette as claimed in claim 9, wherein each housing part comprises two windows consisting of two transparent members and webs connecting said transparent members to each other, and wherein each two transparent members which are located opposite one another form said guide faces for the tape rolls.

Claim 13

A window arrangement for a tape cassette, especially a magnetic tape cassette, said cassette comprising a housing part having at least two apertures and also having recesses, and said cassette further comprising at least two transparent members for covering said apertures, and comprising webs which connect and form a common carrier, distinct from said housing part, for said transparent members, said webs corresponding to the recesses in said housing part of the cassette so as to insure a correct positioning of said webs and said transparent members relatively to said housing part.

Claim 14

A window arrangement for a tape cassette, especially a magnetic tape cassette, said cassette comprising a housing part having at least two apertures and also having recesses, and said cassette further comprising at least two transparent members for covering said apertures, and comprising webs which connect and form a common carrier, distinct from said housing part, for said transparent members, said webs corresponding to the recesses in said housing part of the cassette so as to insure a correct positioning of said webs and said transparent members relatively to said housing part.

Claim 15

An arrangement as claimed in claim 11, wherein said webs have a thickness less than the thickness of the housing parts of the cassette and said transparent members have a thickness substantially the same as the thickness of the walls of the housing parts.

Claim 16

An arrangement as claimed in claim 11, wherein said webs are narrow and are arranged at a distance from one another and delimit a hole.

Claim 17

An arrangement as claimed in claim 11, wherein each transparent member has an edge portion bent upwards at 90° for forming part of the side wall of the cassette housing when assembled with the cassette housing.

Claim 18

An arrangement as claimed in claim 11, wherein the webs together with the at least two transparent members are an injection molding and a gate mark is located on one of the webs.
