Abstract
An image transfer device for transferring an electro-photographically formed image onto a transfer medium comprises grip means for gripping the transfer medium, supporting and moving means for supporting the grip means and moving it cyclically in an endless form, feed means for feeding the transfer medium to be gripped by the grip means, the feed means having a movable paper guide plate disposed adjacent to the path of cyclical movement of the grip means, corona transfer means for transferring the image onto the transfer medium gripped by the grip means, separator means for separating the transfer medium from the grip means, transport means for transporting the separated transfer medium, and control means for causing all of the above-mentioned means to cooperate with one another.
Claims16
An image transfer device for transferring an electrophotographically formed image onto a transfer medium, comprising:
- means for gripping the transfer medium;
- supporting and moving means for supporting said gripping means and moving the same cyclically in an endless path;
- means for feeding the transfer medium to be gripped by said gripping means, said feeding means having a movable paper guide plate disposed adjacent to the path of cyclical movement of said gripping means for guiding the transfer medium into engagement with said gripping means, and having means for moving said guide plate away from said gripping means to permit unimpeded continuous movement of the transfer medium as it is guided to said gripping means and subsequently carried away thereby;
- corona transfer means for transferring said image onto said transfer medium gripped by said gripping means;
- separator means for separating said transfer medium from said gripping means;
- and
- transport means for transporting the separated transfer medium.
An image transfer device for transferring an electrophotographically formed image onto a transfer medium, comprising:
- means for gripping the transfer medium;
- supporting and moving means for supporting said gripping means and moving the same cyclically in an endless path;
- means for feeding the transfer medium to be gripped by said gripping means, said feeding means having a paper guide plate disposed adjacent to the path of cyclical movement of said gripping means for guiding the transfer medium into engagement with said gripping means;
- discharge means having a guide plate disposed adjacent to said feed means for guiding a transfer medium which is unsuccessfully gripped by said gripping means;
- corona transfer means for transferring said image onto said transfer medium gripped by said gripping means;
- separator means for separating said transfer medium from said gripping means;
- transport means for transporting the separated transfer medium;
- and
- control means for controlling the operation of all of said means to cooperate with one another.
An image transfer device for transferring an electrophotographically formed image onto a transfer medium, comprising:
- gripping means having a plurality of units, spaced transversely of the direction of movement of the transfer medium for gripping the transfer medium at the leading end thereof, and a regulating mechanism for regulating the applied force of each of said gripping units;
- supporting and moving means for supporting said gripping means and moving the same cyclically in an endless path;
- feed means for feeding the transfer medium to be gripped by said gripping means, said feed means having a paper guide plate disposed adjacent to the path of cyclical movement of said gripping means for guiding the transfer medium into engagement with said gripping means;
- corona transfer means for transferring said image onto said transfer medium gripped by said gripping means;
- separator means for separating said transfer medium from said gripping means;
- transport means for transporting the separated transfer medium;
- and
- control means for controlling the operation of all of said means to cooperate with one another.
An image transfer device for transferring an electrophotographically formed image onto a transfer medium, comprising:
- grip means for gripping the transfer medium;
- supporting and moving means for supporting said gripping means in an electrically insulated relationship with the body of said device and for moving said gripping means cyclically in an endless path;
- feed means for feeding the transfer medium to be gripped by said grip means, said feed means having a paper guide plate disposed adjacent to the path of cyclical movement of said gripping means for guiding the transfer medium into engagement with said gripping means;
- corona transfer means for transferring said image onto said transfer medium gripped by said gripping means;
- separator means for separating said transfer medium from said gripping means;
- discharger means disposed adjacent to said separator means to act on said transfer medium;
- transport means for transporting the separated transfer medium;
- and
- control means for controlling the operation of all of said means to cooperate with one another.
