Abstract

Abstract A continuous form and cutform feeding unit for a printer. The feeding unit permits feeding a continuous form and cutforms utilizing a cutform feeding arrangement and a continuous form tractor feed. In order to permit either type of form to be fed to a main body of a printer, through a single form feeding passage, a cutform feeding passage and a continuous form feeding passage are provided upstream of the single form feeding passage. In the continuous form feeding passage, a continuous form cutting apparatus is operable to cut a continuous form in response to a signal such as for the beginning of the feeding of cutforms.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 142 words
An apparatus for feeding a continuous form and cutforms which is unitized and is able to be mounted on and removed from the main body of a business machine, comprising: a single form feeding passage to the main body of said business machine, a cutform feeding passage for feeding cutforms to said single form feeding passage and a cutform feeding means located upstream thereof, a continuous-form feeding passage for feeding a continuous form to said single form feeding passage and a tractor for feeding a continuous form located upstream thereof, and a continuous-form cutting means provided in said continuous-form feeding passage, which operates in response to a signal for causing the continuous form to be cut so that cutforms can be fed after cutting and ejecting the continuous form if the cutforms are to be fed between uses of the continuous form.
Claim 2
Independent Claim 142 words
An apparatus for feeding a continuous form and cutforms which is unitized and is able to be mounted on and removed from the main body of a business machine, comprising: a single form feeding passage to the main body of said business machine, a cutform feeding passage for feeding cutforms to said single form feeding passage and a cutform feeding means located upstream thereof, a continuous-form feeding passage for feeding a continuous form to said single form feeding passage and a tractor for feeding a continuous form located upstream thereof, and a continuous-form cutting means provided in said continuous-form feeding passage, which operates in response to a signal for causing the continuous form to be cut so that cutforms can be fed after cutting and ejecting the continuous form if the cutforms are to be fed between uses of the continuous form.
Claim 3
Dependent Claim 35 words
An apparatus for feeding a continuous form and cutforms as claimed in claim 1 wherein said cutform feeding means includes a form cassette which can be mounted on and removed from said cutform feeding means.
Claim 4
Dependent Claim 41 words
An apparatus for feeding a continuous form and cutforms as claimed in claim 1 wherein said continuous form has perforations perpendicular to the moving direction of the continuous form, and said continuous-form cutting means cuts the continuous form along said perforations.
Claim 5
Independent Claim 201 words
An apparatus for feeding a continuous form and cutforms which is contained in a single unit and is operable to be mounted upon and removed from the main body of a business machine, comprising: a single form feeding passage to the main body of a business machine; a cutform feeding passage for defining cutforms to the single form feeding passage; means for feeding cutforms through the cutform feeding passage; a continuous form feeding passage for feeding a continuous form to the single form feeding passage; means for feeding a continuous form through the continuous form feeding passage; continuous form cutting means in the continuous form feeding passage for cutting the continuous form in response to a signal; means, responsive to a command to switch from feeding a continuous form to feeding cutforms, for determining if a continuous form is in the continuous form feeding passage; and means, responsive to a determination that a continuous form is in the continuous form feeding passage, for providing said signal to the continuous form cutting means, so that after it is cut the continuous form is fed out of the single form feeding passage permitting cutforms to be fed through the single form feeding passage.
Claim 6
Independent Claim 201 words
An apparatus for feeding a continuous form and cutforms which is contained in a single unit and is operable to be mounted upon and removed from the main body of a business machine, comprising: a single form feeding passage to the main body of a business machine; a cutform feeding passage for defining cutforms to the single form feeding passage; means for feeding cutforms through the cutform feeding passage; a continuous form feeding passage for feeding a continuous form to the single form feeding passage; means for feeding a continuous form through the continuous form feeding passage; continuous form cutting means in the continuous form feeding passage for cutting the continuous form in response to a signal; means, responsive to a command to switch from feeding a continuous form to feeding cutforms, for determining if a continuous form is in the continuous form feeding passage; and means, responsive to a determination that a continuous form is in the continuous form feeding passage, for providing said signal to the continuous form cutting means, so that after it is cut the continuous form is fed out of the single form feeding passage permitting cutforms to be fed through the single form feeding passage.
