Abstract: To provide an image forming apparatus having a sheet processing apparatus installed in an in-body space, capable of discharging sheets of different sizes without interfering with discharge operation of the sheet processing apparatus in a compact configuration. An image forming apparatus has a sheet binding unit disposed in an in-body space part thereof, a first conveying path for conveying the sheet discharged to the in-body space part toward the sheet binding unit, and a second conveying path for conveying the sheet discharged to the in-body space part toward a second stack tray that stacks thereon the sheet vertically below a first stack tray disposed outside the in-body space part. The second conveying path extends, inside the in-body space part, substantially horizontally between an image forming part and the sheet binding unit.

Abstract: To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, upon receiving a printing command, a main body control section checks information on an ink discharge amount in printing on a sheet, the number of sheets, sheet type and printing mode (two-side/one-side). By this means, the section recognizes weight of the bunch of sheets formed on the processing tray, and when determining that the weight is heavier than predetermined weight, deceases an upper limit value of the number of sheets of a bunch of sheets formed at a time to report to a user.

Abstract: To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, a post-processing control section receives information on an ink discharge amount, the number of sheets, sheet type, and printing mode (two-side/one-side) in printing on sheets from a main body control section of an image forming unit A, in forming a bunch of sheets on the processing tray. The control section thereby recognizes weight of a bunch of sheets formed on the processing tray, and when the section determines that the weight is heavier than predetermined weight, decreases a rotation velocity of a drive motor of a sheet bunch transport means, or increases a current amount applied to the drive motor. By this means, torque of the motor is increased, and the bunch of sheets is reliably discharged to the first stack tray.

Abstract: Disclosed herein is a medium conveying apparatus in which the time for unjamming can be shortened. The medium conveying apparatus includes rollers configured to convey a card Ca, a rotary unit F provided in a medium conveyance path and configured to hold and rotate the card Ca, a sensor SN26 arranged downstream the rotary unit F on the medium conveyance path and, and a control section. The control section controls a first card-conveyance motor for driving the rollers to convey the card Ca into the rotary unit F, and determines whether the sensor SN26 detects the card Ca. The sensor SN26 is arranged at the same distance as a sensor SN3 or a shorter distance than the sensor SN3, from the rotary unit F.

Abstract: A transfer apparatus includes a transfer device which performs transfer processing to transfer a transfer layer or protection layer to first and second faces of a card-shaped recording medium, a correcting device which performs decurl processing to correct a curl of the recording medium to which the transfer layer is transferred, a transfer sequence determining device which determines a transfer sequence to the first face and the second face of the recording medium, and a control device which controls the transfer device and the correcting device. The transfer sequence determining device determines the transfer sequence so that the transfer processing is performed alternately on the first face and the second face at least once. The control device performs the decurl processing with the correcting device for the difference between the number of times of the transfer processing on the first face and the second face of the recording medium.

Abstract: The present invention is to provide a transfer apparatus which can effectively correct a curl of a card and prevent deterioration of the card. The transfer apparatus transfers a transfer layer of a transfer film with a transfer roller to both faces of a card, a transfer unit which includes the transfer roller is structured to perform transfer processing for a plurality of times on at least one face of the card. A controller controls transfer sequence of transfer processing so that transfer processing is performed alternately on a first face (front face) and a second face (back face) of a card and so that the number of times of decurl processing with a decurl mechanism is smaller than the number of times of transfer processing.

Abstract: To provide a printing apparatus without waste of a ribbon panel in using a two-side dedicated ribbon, a printing apparatus 1 capable of printing on both surfaces of a printing medium performs two-side printing using an ink ribbon 41 with a color ribbon panel 41a and monochrome ribbon panel 41b configured in a face sequential manner. At this point, the apparatus detects a position of each ribbon panel, judges a type (color or monochrome) of a next usable nearest ribbon panel of the ink ribbon 41, judges which type of the ribbon panel (color or monochrome) is used for printing data sent from a higher apparatus 201, and compares the type of the next usable nearest ribbon panel with the ribbon panel judged with the printing data to determine the printing order on the printing medium.

A recording medium contact point of the peeling member is set in the same position as a first tangent passing through a recording medium contact point of the transfer member and a contact of the recording medium of a transport member and a recording medium contact point of the support member is set in the same position as a second tangent passing through the recording medium contact point of the transfer member and the recording medium contact point of the peeling member or on the transfer platen side relative to the second tangent.
