Abstract
Abstract A paper feeding device, used in a copier, has a swivel cassette capable of turning to a longitudinal feed position for longitudinal paper feed and to a lateral feed position for lateral paper feed. The paper feeding device is so arranged that the swivel cassette is automatically turned to a priority-given position when power is turned on, auto clear is executed or an all clear key is depressed. The paper feeding device has a memory for storing the number of sheets supplied from a respective one of the feed positions of the swivel cassette. A paper feed position used high frequency is regarded as the priority-given position by comparing the stored numbers with each other, so that the swivel cassette is set to the paper feed position used high frequency when power is turned on, auto clear is executed or the all clear key is depressed. Accordingly, the user can save the trouble of changing over to that feed position used with high frequency, and this feature improves the convenience of the copier.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
A paper feeding device for feeding paper in longitudinal and lateral directions, comprising: a swivel cassette for accommodating paper and being capable of turning to a longitudinal feed position for longitudinal paper feed and a lateral feed position for lateral paper feed; turning means for turning said swivel cassette; conveying means for taking paper out of said swivel cassette and conveying the paper; memory means for storing a number of sheets supplied from the swivel cassette at longitudinal feed position and a number of sheets supplied from said swivel cassette at lateral feed position; selecting means for selecting a priority position between said longitudinal and lateral positions according to the stored number of sheets supplied from said swivel cassette at longitudinal feed position and the stored number of sheets supplied from said swivel cassette at lateral feed position; and control means for controlling the said turning means to position said swivel cassette to the selected priority position on the basis of a selection of said selecting means.
Claim 2
Dependent Claim
167 words
A paper feeding device for feeding paper in longitudinal and lateral directions, comprising: a swivel cassette for accommodating paper and being capable of turning to a longitudinal feed position for longitudinal paper feed and a lateral feed position for lateral paper feed; turning means for turning said swivel cassette; conveying means for taking paper out of said swivel cassette and conveying the paper; memory means for storing a number of sheets supplied from the swivel cassette at longitudinal feed position and a number of sheets supplied from said swivel cassette at lateral feed position; selecting means for selecting a priority position between said longitudinal and lateral positions according to the stored number of sheets supplied from said swivel cassette at longitudinal feed position and the stored number of sheets supplied from said swivel cassette at lateral feed position; and control means for controlling the said turning means to position said swivel cassette to the selected priority position on the basis of a selection of said selecting means.
Claim 3
Dependent Claim
33 words
A paper feeding device according to claim 1, wherein said selecting means selects a paper feed position representing the greater number of sheets between the longitudinal feed position and the lateral feed position.
Claim 4
Dependent Claim
43 words
A paper feeding device according to claim 1, wherein said selecting means includes means for comparing the number of sheets supplied from said swivel cassette at longitudinal feed position with the number of sheets supplied from said swivel cassette at lateral feed position.
Claim 5
Dependent Claim
50 words
A paper feeding device according to claim 1, wherein said control means includes detecting means for detecting a present position of said swivel cassette, and wherein said control means maintains the present position of said swivel cassette when the present position of said swivel cassette coincides with the priority position.
Claim 6
Dependent Claim
181 words
A paper feeding device, used in a copier which generates a signal to turn a paper cassette to a priority-given feed position, for feeding paper in longitudinal and lateral directions, comprising: a swivel cassette for accommodating paper and being capable of turning a longitudinal feed position for longitudinal paper feed and a lateral feed position for lateral paper feed; turning means for turning said swivel cassette; conveying means for taking paper out of said swivel cassette and conveying the paper; memory means for storing a number of sheets supplied from said swivel cassette at longitudinal feed position and a number of sheets supplied from said swivel cassette at lateral feed position; selecting means for selecting a priority position between said longitudinal and lateral positions according to the stored number sheets supplied from said swivel cassette at lateral feed position; and control means for controlling said turning means to position said swivel cassette to the selected priority position on the basis of a selection of said selecting means when a signal to turn the cassette to the priority-given position has been generated.
Claim 7
Dependent Claim
181 words
A paper feeding device, used in a copier which generates a signal to turn a paper cassette to a priority-given feed position, for feeding paper in longitudinal and lateral directions, comprising: a swivel cassette for accommodating paper and being capable of turning a longitudinal feed position for longitudinal paper feed and a lateral feed position for lateral paper feed; turning means for turning said swivel cassette; conveying means for taking paper out of said swivel cassette and conveying the paper; memory means for storing a number of sheets supplied from said swivel cassette at longitudinal feed position and a number of sheets supplied from said swivel cassette at lateral feed position; selecting means for selecting a priority position between said longitudinal and lateral positions according to the stored number sheets supplied from said swivel cassette at lateral feed position; and control means for controlling said turning means to position said swivel cassette to the selected priority position on the basis of a selection of said selecting means when a signal to turn the cassette to the priority-given position has been generated.
Claim 8
Dependent Claim
33 words
A paper feeding device according to claim 5, wherein said selecting means selects a paper feed position representing the greater number of sheets between the longitudinal feed position and the lateral feed position.
Claim 9
Dependent Claim
