Abstract
A sheet feed device has a sheet supply tray in which sheets to be fed are stored, a roller mechanism which ejects each printed sheet on to a sheet holding part, and a cover member which is placed between a sheet supply side on which each sheet is fed before printing and a sheet ejection side on which each sheet is fed after printing. In the sheet feed device, each sheet supplied from the sheet supply tray changes its sheet feed direction approximately 180 degrees before being ejected to the sheet holding part. Part of the cover member on the sheet holding part's side is provided with a first projecting part which lets the ejected sheets be held in the sheet holding part while being bent substantially in an S-shape.
Claims16
A sheet feed device, comprising:
- a sheet supply tray in which sheets to be fed are stored;
- a roller mechanism configured to eject each sheet after being printed on;
- a sheet holding part configured to hold each printed sheet ejected by the roller mechanism;
- and
- a cover member which is placed between a sheet supply side on which each sheet is fed before printing and a sheet ejection side on which each sheet is fed after printing,
- wherein each sheet supplied from the sheet supply tray changes its sheet feed direction approximately 180 degrees before being ejected to the sheet holding part, and
- wherein part of the cover member on a side of the sheet holding part is provided with a first projecting part which allows the ejected sheets to be held in the sheet holding part while being bent substantially in an S-shape.
A sheet feed device, comprising:
- a sheet supply tray in which sheets to be fed are stored;
- a roller mechanism configured to eject each sheet after being printed on;
- a sheet holding part configured to hold each printed sheet ejected by the roller mechanism;
- and
- a cover member which is placed between a sheet supply side on which each sheet is fed before printing and a sheet ejection side on which each sheet is fed after printing, wherein:
- each sheet supplied from the sheet supply tray changes its sheet feed direction approximately 180 degrees before being ejected to the sheet holding part, and
- a face of the cover member on a side of the sheet holding part is provided with a first projecting part which allows the ejected sheets to be held in the sheet holding part while being bent substantially in an S-shape, and
- part of an opposing part opposing the first projecting part is provided with a second projecting part projecting toward the cover member, and
- an apex of the second projecting part is placed above an ejecting part, defined as a point of contact of the sheet with the roller mechanism that is the most downstream in the sheet feed direction, and below an apex of the first projecting part.
A sheet feed device, comprising:
- a sheet supply tray in which sheets to be fed are stored;
- a roller mechanism configured to eject each sheet after a prescribed process;
- a sheet holding part configured to hold each sheet ejected by the roller mechanism;
- and
- a cover member which is placed between a sheet supply side on which each sheet is fed before the prescribed process and a sheet ejection side on which each sheet is fed after the prescribed process, wherein:
- each sheet supplied from the sheet supply tray changes its sheet feed direction approximately 180 degrees before being ejected to the sheet holding part, and
- part of the cover member on a side of the sheet holding part is provided with a first projecting part which allows the ejected sheets to be held in the sheet holding part while being bent substantially in an S-shape.
An image formation device including a sheet feed device, comprising:
- a sheet supply tray in which sheets to be fed are stored;
- a roller mechanism configured to eject each sheet after image formation;
- a sheet holding pat configured to hold each sheet ejected by the roller mechanism;
- and
- a cover member which is placed between a sheet supply side on which each sheet is fed before image formation and a sheet ejection side on which each sheet is fed after image formation, wherein:
- each sheet supplied from the sheet supply tray changes its sheet feed direction approximately 180 degrees before being ejected to the sheet holding part, and
- part of the cover member on a side of the sheet holding part is provided with a first projecting part which allows the ejected sheets to be held in the sheet holding part while being bent substantially in an S-shape.
