Abstract
A recording apparatus has a first positioning part positioned on a base chassis, and a second positioning part for positioning a guide shaft for guiding a carriage carrying a recording head for recording images on a transported sheet, both provided on the same face of each of a left side plate and right side plate. A third positioning part for positioning a transporting roller for transporting sheets along a sheet transporting path is provided on at least one of these faces. Thus, a recording apparatus can be provided wherein the precision of the chassis configuration and the rigidity thereof is improved, and parts can be standardized, at low cost.
Claims29
A recording apparatus for recording on a recording medium with a recording head, said recording apparatus comprising:
- a base chassis;
- a transporting member for transporting the recording medium;
- a carriage for mounting the recording head;
- a guide member for guiding said carriage;
- a carriage motor for effecting movement of said carriage;
- a second chassis for holding said carriage motor;
- two side plates connected to opposite ends of said base chassis across a transporting path of the recording medium transported by said transporting member;
- first positioning parts, disposed on a predetermined face of each of said two side plates, for positioning said side plates on said base chassis;
- second positioning parts, disposed on the predetermined face of each of said two side plates, for positioning said guide member on said side plates;
- a third positioning part, disposed on one of said two side plates, for positioning said transporting member on at least the one of said side plates;
- fourth positioning parts, disposed on the predetermined face of each of said two side plates, for positioning said second chassis on said side plates;
- and
- a fifth positioning part, disposed on said base chassis, for positioning said transporting member on said base chassis.
A recording apparatus for recording on a recording medium with a recording head, said recording apparatus comprising:
- a base chassis;
- a conveying roller for conveying the recording medium;
- a guide member for guiding the recording head in main scanning directions;
- a scanning motor for effecting movement of the recording head;
- a second chassis for holding said scanning motor;
- first and second side plates separate from said base chassis, said first and second side plates being connectable to opposite sides of said base chassis;
- means for connecting and relatively positioning said first and second side plates to the opposite sides of said base chassis;
- means for connecting and relatively positioning said guide member to said first and second side plates;
- means for connecting and relatively positioning said conveying roller to at least one of said first and second side plates;
- means for positioning said second chassis on said first and second side plates;
- and
- means for positioning said conveying roller on said base chassis.
