Simplified paper passage in a printer

A printer, comprising:

• a base frame having a pair of opposing side walls;
• a transferring device supported by said base frame to transfer paper along a paper passage;
• a printing head adapted to perform a printing operation for the paper;
• a carriage frame extending between said pair of side walls for directly supporting a carriage slidably in a direction perpendicular to the paper transferring direction of said transferring device, said carriage carrying said printing head thereon;
• a guide surface formed on said base frame, said guide surface constituting one surface of a portion of said paper passage;
• and
• a guide member provided on said carriage frame, said guide member being spacedly opposed to said guide surface and constituting a portion of said paper passage between said guide member and said guide surface for guiding the paper to said transferring device.

A printer, comprising:

• a base frame having a pair of opposing side walls;
• a transferring device for transferring paper along a paper passage toward a discharge opening formed at one end of said base frame;
• a printing head adapted to perform a printing operation for the paper;
• a carriage frame extending between the pair of side walls for directly supporting a carriage slidably in a direction perpendicular to the paper transferring direction of said transferring device, said carriage carrying said printing head thereon;
• and
• a closure element provided on said carriage frame to cover an upper side portion of said paper passage.

A printer, comprising:

• a transferring device for transferring paper along a paper passage toward a discharge opening formed at one end of said base frame;
• a printing head adapted to perform a printing operation for the paper;
• a carriage frame for directly supporting a carriage slidably in a direction perpendicular to the paper transferring direction of said transferring device, said carriage carrying said printing head thereon;
• an upwardly open guide surface formed on said base frame to form one surface of said paper passage;
• and
• a closure element provided on said carriage frame to cover an upper surface of said paper passage, wherein said carriage frame is supported by said base frame so that it is opposed to said guide surface from above.

A carriage frame extending between side frames of a printer, comprising:

• a flat center section extending between the side frames of the printer;
• a first end bent to present a block U-shape in cross-section, an arm of the block U-shape opposite an arm formed by the center section providing a guide bar for a printer carriage;
• and
• a second end bent in a direction substantially opposite to a base of the block U-shape first end, the bent second end providing a portion of a paper guide path.
