PURPOSE:To facilitate cleaning operation by unlocking a platen from a locking device and releasing a shutter mechanism through one lever operation. CONSTITUTION:In a figure, 60 is an operation lever for manual stopper unlocking, which is supported pivotally on holders 62 and 63 fixed to a side plate through a pin 61 and energized upward by a spring 65. This lever 60 while displaced to a stationary position by the spring force of the spring 65 engages a link 42 and the upper edge of an arm 64. Once the lever 60 is pressed in a direction E, the lever 60 presses down the arm 64 and one end of the link 42 to press down the stopper 55 in a direction F through the link 42, and consequently the platen is uncloked; and the arm 64, on the other hand, is rotated in a direction G to elevate a pin 24 in a direction C, thereby rotating an actuator in a direction H. |
