Sheet discharging device, method of controlling sheet discharging device, processing device, and recording system

A method of controlling a sheet discharging device including:

• a pair of medium supporting portions configured to support a medium transported in a transport direction, the medium supporting portion being configured to swing;
• a stacking portion which is provided vertically below the pair of medium supporting portions and on which the medium dropped by moving the pair of medium supporting portions in a width direction intersecting the transport direction is stacked, the stacking portion being configured to move up and down;
• and
• a detecting portion that detects swinging of the medium supporting portions, the method comprising:
• supporting the transported medium by using the pair of medium supporting portions;
• dropping the medium supported by the pair of medium supporting portions by moving the pair of medium supporting portions in the width direction;
• receiving the dropped medium on the stacking portion and stacking the received medium on a stacking surface;
• after stacking, on the stacking surface, the medium dropped from the pair of medium supporting portions, moving the pair of medium supporting portions in a direction opposite to a direction at a time of the dropping, and stopping the medium supporting portions;
• bringing the medium on the stacking surface into contact with lower surfaces of the medium supporting portions by raising the stacking portion after stopping the pair of medium supporting portions;
• detecting presence or absence of the swinging of the medium supporting portions due to the contact of the medium;
• and
• lowering the stacking portion based on a detection result.

A processing device comprising:

• a processing section that performs processing on a medium;
• a medium supporting portion configured to support the medium transported in a transport direction from the processing section, the medium supporting portion being configured to swing;
• a stacking portion which is provided vertically below the medium supporting portion and on which the medium dropped from the medium supporting portion is stacked, the stacking portion being configured to move up and down;
• and
• a detecting portion that detects swinging of the medium supporting portion, wherein
• the detecting portion detects the swinging of the medium supporting portion when the medium on the rising stacking portion comes into contact with a lower surface of the medium supporting portion.

A recording system comprising:

• a recording device including
• a recording section that performs recording on a medium, and
• a discharging portion that discharges the medium on which recording is performed by the recording section;
• and
• a processing device including
• a medium introducing portion that introduces the medium discharged from the discharging portion,
• a processing section that performs processing on the medium introduced from the medium introducing portion,
• a medium supporting portion configured to support the medium transported in a transport direction from the processing section, the medium supporting portion being configured to swing,
• a stacking portion which is provided vertically below the medium supporting portion and on which the medium dropped from the medium supporting portion is stacked, the stacking portion being configured to move up and down, and
• a detecting portion that detects swinging of the medium supporting portion, wherein
• the detecting portion detects the swinging of the medium supporting portion when the medium on the rising stacking portion comes into contact with a lower surface of the medium supporting portion.
