Claims
- 1. A printing apparatus comprising:
- a printing station including a platen and a printing head, wherein a first or second printing medium guided by said platen is scanned by said printing head for recording information;
- first driving means including a first pair of rollers positioned ahead of said printing station for transporting said first or second printing medium toward said printing station, at least one of said rollers of said first pair being resilient and said first or second printing medium being guided by and between said first pair of rollers;
- second driving means including a second pair of rollers positioned behind said printing station for drawing said first or second printing medium from said printing station, at least one of said rollers of said second pair being resilient and said first or second printing medium being guided by and between said second pair of rollers;
- a casing enclosing said printing station, said first driving means and said second driving means;
- first guide means defining a first entrance at an upper surface of said casing for guiding said first printing medium along a curved path to and between said first pair of rollers and having a portion that is spaced apart from one of said pair of rollers by a distance that is somewhat smaller than the thickness of said first printing medium; and
- second guide means defining a second entrance at a lower surface of said casing for guiding said second printing medium along a straight path to and between said first pair of rollers;
- said second driving means defining an exit for said first or second printing medium along a straight path and being positioned with respect to said first guide means so that said first printing medium enters and leaves said printing apparatus on the same side thereof; and
- said first and second driving means being mounted adjacent to said printing station.
- 2. A printing apparatus according to claim 1, wherein said first driving means and said second driving means are approximately flush with said first guide means.
- 3. A printing apparatus according to claim 1, further comprising means for operating said first driving means and said second driving means at an equal operating speed.
- 4. A printing apparatus comprising:
- a printing station including a platen and a printing head, wherein a first or second printing medium guided by said platen is scanned by said printing head for recording information;
- first driving means positioned ahead of said printing station for transporting said first or second printing medium toward said printing station;
- second driving means positioned behind said printing station for drawing said first or second printing medium from said printing station;
- a guide plate defining a first entrance to said first driving means and having a portion that is spaced apart from said first driving means by a distance that is somewhat smaller than the thickness of said first printing medium;
- second guide means defining a second entrance to said first driving means;
- means defining an exit from said second driving means; and
- a casing having a lower side and an upper side and covering said printing station, said first and second driving means, and said first and second guide means;
- said first driving means and said second driving means being substantially flush with said second guide means, whereby said second printing medium entering said second entrance is guided from said second entrance in a straight path to said second driving means;
- said second entrance being on the lower side of said casing, said exit being on the upper side of said casing, and said second entrance being substantially flush with said exit; and
- said first entrance being on the upper side of said casing and adjacent to said exit.
