7、AL 1. Scope This part applies only to cassette recording and reproducing systems. SECTION TWO - MECHANICAL REQUIREMENTS 12. Replacement: Mechanical requirements and dimensions of cassette recording systems any cassette recorder or player are given in Figures 1 to 12, pages 16 to 24. Constructional d
8、ata which standardize the cassette to secure interchangeability of cassettes on D ThX-, Y- and Z-reference planes in the figures have been defined as follows: o The Z-reference plane is the plane established by three points which are positioned half of the distance between three reference areas U, V
9、 and W on one cassette side and three correspond- ing ones on the other side (see Figure 9, page 22). o The X-reference plane per cassette side is defined as the common tangential plane at the rear of both positioning holes per side, perpendicular to the Z-reference plane. o The Y-reference plane is
10、 defined perpendicular to the relevant X- and the Z-reference plane and is situated at the mid-point of the centres of the reference holes (see Section D-D in Figure 2, page 17). Note. - These definitions show that a cassette can fulfil the dimensional requirements in this standard only on the basis
11、 of two X-reference planes and two Y-reference planes. Furthermore, the following requirements shall apply: IEC page 91 Copyright British Standards Institution Provided by IHS under license with BSI - Uncontrolled Copy Licensee=University of Hong Kong/5910986001 Not for Resale, 11/20/2006 00:53:45 M
