<p>PURPOSE:To promote miniaturization and to perform high reliable and sure assemblage. CONSTITUTION:As to 1st and 2nd projecting guide parts 17 and 19 to be provided in juxtaposition in the moving direction of a cassette holder 16, the 2nd projecting guide part 19 is formed to project out longer than the 1st projecting guide part 17. Then, as to 1st and 2nd guide groove parts 14 and 15 of a metal plate 10, the 2nd guide groove part 15 is formed deeper than the 1st guide groove part 14 in their grooves, and in the 2nd guide groove part 15, 1st and 2nd inserting holes capable of allowing only the 1st projecting guide part 17 to pass through, are formed. By this method, the 1st projecting guide part 17 is made to pass through the 1st inserting hole, the 2nd guide groove part 15 and the 2nd inserting hole and is housed in the 1st guide groove part 14, while the 2nd projecting guide part 19 is housed directly in the 2nd guide groove part 15.</p> |
