Impact type recording apparatus having reduced impact sound during return of the hammer

An impact type recording apparatus for recording on a recording medium, said apparatus comprising:

• an image holding member;
• impacting means for impacting said image holding member to the recording medium to record on the recording medium;
• return speed detecting means for detecting a speed at which said impacting means returns along a return path to an initial position after said image holding member impacts the recording medium;
• and
• controlling means for controlling a timing for applying a braking force of only one pulse to said impacting means at a point along the return path when said impacting means returns to the initial position in accordance with detection results produced by said return speed detecting means, wherein said point along the return path is determined as a function of the detected return speed.

An impact type recording apparatus for recording on a recording medium, said apparatus comprising:

• an image holding member;
• impacting means for impacting said image holding member to the recording medium to record on the recording medium;
• return speed detecting means for detecting a speed at which said impacting means returns along a return path to an initial position after said image holding member impacts the recording medium;
• braking means for applying a braking force of only one pulse to said impacting means at a point along the return path to decrease the return speed of said impacting means when said impacting means returns to said initial position;
• and
• controlling means for controlling a timing when said braking means starts to apply said braking force in accordance with detection results produced by said return speed detecting means, wherein said point along the return path is determined as a function of the detected return speed.

An impact type recording apparatus for recording on a recording medium, said apparatus comprising:

• a platen;
• a character wheel having a plurality of character means;
• hammer means for impacting said character member selected from said plurality of character members of said character wheel to said platen through the recording medium and an ink ribbon;
• return speed detecting means for detecting a speed at which said hammer means returns along a return path to an initial position after said hammer means impacts said platen;
• braking means for applying a braking force of only one pulse to said hammer means at a point along the return path to decrease the return speed of said hammer means when said hammer means returns to said initial position;
• and
• controlling means for controlling a timing when said braking means starts to apply said braking force to said hammer means in accordance with detection results produced by said return speed detecting means, wherein said point along the return path is determined as a function of the detected return speed.

An impact type recording apparatus for recording on a recording medium, said apparatus comprising:

• a platen;
• a carriage movable along said platen;
• a hammer provided on said carriage;
• driving means for causing said hammer to project to said platen so as to record on the recording medium;
• detecting means for detecting a return speed at which said hammer returns from said platen along a return path to an initial position after said hammer impacts said platen;
• braking means for applying a braking force of only one pulse to said hammer at a point along the return path to decrease the return speed of said hammer when said hammer returns to said initial position;
• and
• controlling means for controlling the timing when said braking means starts to apply said braking force to said hammer in accordance with detection results produced by said detecting means, wherein said point along the return path is determined as a function of the detected return speed.
