Abstract:
1. An imaging apparatus, comprising: a fixed print head; a platen, capable of contacting or separating from the print head and having a roll shaft; and a rotating shaft of the platen, mounted in parallel with the roll shaft, capable of rotating within a certain range of angle, and sleeved with a first shaft bush, an elastic component, and a second shaft bush sequentially from two ends towards a center thereof, wherein the second shaft bush is solidly connected to the rotating shaft, two ends of the elastic component are respectively connected to the first shaft bush and the second shaft bush, the first shaft bush has a first connection hole and a second connection hole, the one end of the rotating shaft is fitted in the first connection hole, and one end of the roll shaft of the platen is fitted in the second connection hole; wherein when the platen separates from the print head, the first shaft bush sways up and down along with the rotation of the rotating shaft, so as to drive the platen to move up and down; and when the platen contacts the print head, the rotating shaft rotates relative to the first shaft bush, so as to deform the elastic component to generate a torsion.
