<p>PURPOSE:To press securely a pack guide to a descent position and to operate it lightly during ejection by extending a coil spring to an L-shaped link atop of a guide arm, and inverting the load on the spring. CONSTITUTION:When the pack gude is moved down, the L-shaped link 4 engages the pin 3 of a guide arm to extend a coil spring 11 between a spring fitting part 10 and an abutting part 8, and the position of the abutting part 8 is set on the right-hand side of the line l connecting the fitting part 10 and a supporting shaft 6. Therefore, when the link 4 rotates clockwise by a spring 15 during the loading of a cassette, the spring 11 is in front of the line l to draw the link 4 clockwise, holding the pack guide securely at the descent position. Further, when the abutting part 8 goes beyond the line l during ejection, the spring 11 draws the link 4 upward, so the elevation of the pack guide is performed smoothly to realize light operation.</p> |
