Impact dot printer with noise suppression

An impact dot printer comprising:

• a case having at least one opening;
• a print section positioned in said case at least in part in registration with said at least one opening, and having a platen and a print head, said print head confronting said platen;
• a cover positioned to close at least the portion of said at least one opening in registration with said print section;
• said cover including a first cover portion for covering a portion of said at least one opening of said case, said first cover portion having a top plate and at least one side plate formed integrally with said top plate;
• and a second cover portion pivotally mounted on said first cover portion, said second cover portion having a top plate and at least one side plate formed integrally with said top plate;
• said at least one side plate of said first cover portion and said at least one side plate of said second cover portion being shaped so that one of said side plates overlies the other of said plates so that essentially no opening is formed between said at least one side plate of said first cover portion and said at least one side plate of said second cover portion when said second cover portion is pivoted relative to said first cover portion.

An impact dot printer comprising:

• a case having at least one opening;
• a print section positioned in said case at least in part in registration with said at least one opening and having a platen and a print head, said print head confronting said platen;
• said platen and said print head and said at least one opening defining a sheet discharge path beginning at a point of contact between said platen and said print head and extending to said at least one opening;
• a cover positioned to close at least the portion of said at least one opening in registration with said print section;
• said cover including a first cover portion for covering a portion of said at least one opening in said case, said first cover portion having a top plate having a front end and a rear end opposed to said front end;
• a second cover portion having a top plate having a front end adjacent the rear end of said top plate of said first cover portion, said second cover portion being pivotally mounted on said first cover portion along an axial line located essentially at one of said rear end of said first cover portion top plate and said front end of said second cover portion top plate and along the sheet discharge path;
• and
• said rear end of said first cover portion top plate and said front end of said second cover portion top plate being shaped to define respective overlap portions between said top plate of said first cover portion and said top plate of said second cover portion so that essentially no opening is formed between said first cover portion and said second cover portion along said axial line as viewed in a plan view of said top plates of said first and second cover portions, when said second cover portion is pivoted relative to said first cover portion and wherein said overlap portion of said first cover portion extends at least in part into said case.

An impact dot printer comprising:

• a case having at least one opening;
• a print section positioned in said case at least in part in registration with said at least one opening, and having a platen and a print head, said print head confronting said platen;
• a cover positioned to close at least the portion of said at least one opening in registration with and overlying said platen and said print head;
• a silencing device disposed between a portion of said cover and said print section and overlying at least one of said platen and said print head and constructed to reduce the sound of printing from the print section from reaching the exterior of said case and cover;
• and
• a sheet discharge plate positioned intermediate at least a portion of at least one of said print head and said platen and said silencing device to at least in part deflect a sheet of paper in a direction away from said silencing device.

• a cover positioned to close at least the portion of said at least one opening in registration with and overlying said print section;
• a silencing device disposed between a portion of said cover overlying at least a part of said print section and said print section constructed to reduce the sound of printing from the print section reaching the exterior of said case and cover, said silencing device including a sound absorbing member for absorbing sound, said sound absorbing member being selected from the group consisting of foam plastic and rubber;
• and
• a sheet discharge plate positioned entirely within said case and intermediate said print section and said silencing device to at least in part guide a sheet of paper in a direction away from said silencing device .
