Abstract
A media stacker is adapted to accommodate plate-shaped media in a stacked manner. A sensor with which the media stacker is provided is operable to detect a height of the stacked media accommodated in the media stacker.
Claims7
A media processor comprising:
- a media stacker adapted to accommodate plate-shaped media in a stacked manner;
- and
- a sensor operable to detect that a height of the stacked media accommodated in the media stacker reaches a predetermined height, wherein
- the media stacker is provided with the sensor,
- the media stacker includes a bottom face and a side face which define an accommodating space for the media,
- the sensor is provided in the side face,
- the side face is formed with an opening;
- and
- the sensor includes:
- a lever having a protrusion which is retractably protruded from the opening into the accommodating space;
- a supporting member pivotably supporting the lever;
- and
- a sensing element operable to detect a movement of the lever,
- wherein an upper part of the protrusion is formed into an upwardly inclined face toward the side face, and wherein the sensor is configured such that the lever remains retracted into the opening when the stacked media reaches the predetermined height.
