<p>PURPOSE:To simultaneously execute 2 or more operations in one handling of an inject lever once, by providing multi-function on the inject lever. CONSTITUTION:An inject lever 20 is disposed on a base plate 16 so as to be rotatable by a rotary pin 19. A torsion coil spring 96 is wound around the rotary pin 19 and one end of the torsion spring is pressed against the side of the inject lever 20, and the other end is pressed to the side of a guide block 99 of a cassette guide 98. As for guide pins 100, 104 for controlling a position in the horizontal direction, although a pair of guide pins 104 are fixed, the guide pin 100 is formed on the inject lever 29 being freely rotatable, therefore, it becomes movable against the guide pins 104. In this way, all three guide pins 100, 104 and 104 are not fixed but the guide pin 100 is made movable, therefore, a position shift of a cassette in the cassette holder is corrected, and the cassette is positioned exactly.</p> |
