<p>PURPOSE:To attain the visual recognition of a label after cassette loading by placing plural mirrors to a proper tilt angle in interlocking with the falling of a cassette holder. CONSTITUTION:The length of a mirror support expansion bar 110 is expanded or contracted so as to correspond to the change in the interval between the cassette holder 106 and the left end of the mirror 108 due to the change in the tilt of the mirror 108. The relative angle between the mirror connection bar 105 and mirrors 103, 108 are changed respectively by the change in the tilt of the mirror 108 at their right ends and the distance of the right end of the mirrors 103, 108 is kept unchanged while being connected respectively by mirror connection pins 104, 109 respectively, then the tilt of the mirror 103 is changed to keep the parallelism with the mirror 108. Thus, the cassette label visual recognition device reaches the state as shown in figure, the label of the cassette is taken by the mirror 108 and reflected further in the mirror 103. Thus, the visual recognition of the image of label reflected in the mirror 103 is attained.</p> |
