Abstract
Abstract A recording apparatus includes an image bearing member, image forming device for forming images on the image bearing member, a transfer medium, image transferring device for transferring the images from the image bearing member onto the transfer medium, a feeder for feeding the transfer medium to a transfer station, and control system for operatively controlling the transfer device and the feeder with mutually independently set delay times with respect to the start or the stop of operation of the image formation device.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
118 words
A recording apparatus comprising: an image bearing member; means for forming continual images on said image bearing member; means for feeding a continuous transfer material to a transfer station; means for transferring the images formed on said image bearing member onto the continuous transfer material; means for fixing the transferred images on the transfer material; and means, responsive to the start and stop of operation of said image forming means, for controlling the actuation of said feeding means, transferring means, and fixing means at different delayed times from each other to transfer a series of images from said image bearing member onto desired portions of said continuous transfer material irrespective of image location on said image bearing member.
Claim 2
Dependent Claim
118 words
A recording apparatus comprising: an image bearing member; means for forming continual images on said image bearing member; means for feeding a continuous transfer material to a transfer station; means for transferring the images formed on said image bearing member onto the continuous transfer material; means for fixing the transferred images on the transfer material; and means, responsive to the start and stop of operation of said image forming means, for controlling the actuation of said feeding means, transferring means, and fixing means at different delayed times from each other to transfer a series of images from said image bearing member onto desired portions of said continuous transfer material irrespective of image location on said image bearing member.
Claim 3
Dependent Claim
47 words
An apparatus according to claim 1, wherein the delay time for providing the delayed actuation of said transfer means is set by deducting the transient time between when a signal for actuating said transfer means is produced and when said transfer means reaches a stable operating condition.
Claim 4
Dependent Claim
55 words
An apparatus according to claim 1, wherein the delay time for providing the delayed actuation of said feeding means is set by deducting the transient time between when a signal for actuating said feeding means is produced and when said feeding means reaches a state whereat it feeds the transfer material at a stable speed.
Claim 5
Dependent Claim
55 words
An apparatus according to claim 1, wherein the delay time for producing the delayed actuation of said fixing means is set by deducting the transient time between when a signal for actuating said fixing means is produced and when said feeding means reaches a state whereat it feeds the transfer material at a stable speed.
Claim 6
Dependent Claim
29 words
A recording apparatus according to claim 1, wherein said transfer means includes a transfer charger and means for bringing said transfer material into contact with said image bearing member.
Claim 7
Dependent Claim
23 words
A recording apparatus according to claim 5 wherein said control means causes said contacting means to start operating earlier than said transfer charger.
Claim 8
Dependent Claim
34 words
A recording apparatus according to claim 1, wherein said fixing means includes a plurality of rollers with said transfer material interposed therebetween, and wherein said control means controls the pressure contact between said rollers.
Claim 9
Dependent Claim
20 words
A recording apparatus according to claim 7, wherein at least one of said rollers applies heat to the transfer material.
Claim 10
Dependent Claim
31 words
A recording apparatus according to claim 8, further comprising a heat roller provided with a heater, and wherein said heat roller applies heat to said at least one of said rollers.
Claim 11
Dependent Claim
32 words
A recording apparatus according to claim 1, wherein said image formation means includes means for forming electrostatic latent images on said image bearing member and means for developing said electrostatic latent images.
Claim 12
Dependent Claim
31 words
An apparatus according to claim 1, wherein said image forming means includes means for generating a modulation signal which corresponds to the image to be formed on said image bearing member.
Claim 13
Dependent Claim
35 words
An apparatus according to claim 11, wherein said image forming means comprises a beam oscillator for generating a beam for executing recording on said image bearing member and wherein said modulation signal controls the beam.
Claim 14
Dependent Claim
15 words
An apparatus according to claim 12, wherein said beam oscillator is a laser beam oscillator.
Claim 15
Dependent Claim
36 words
A recording apparatus according to claim 14, further comprising means for moving said transfer material in a retracting direction and wherein said control means operatively controls said retracting means before a subsequent image transfer takes place.
Claim 16
Dependent Claim
70 words
A recording apparatus according to claim 14, wherein said image bearing member is a rotatable member and said image forming means and said transfer means are provided adjacent to the surface of said rotatable member and wherein said apparatus further comprises means for generating a series of pulse signals during the rotation of said rotatable member, said delay times being set by the pulses from said pulse signal generating means.
Claim 17
Dependent Claim
21 words
An apparatus according to claim 14, wherein said continuous transfer material is fan-folded paper and said feeding means includes a tractor.
