Convertible printed product collecting assembly
A convertible printed product collecting assembly (10) includes a collecting fabric (11) rolled on a rotatable fabric bearing rod. Supporting legs (13) have a lower end tiltably connected to a printer (18) and are tillable in the collecting fabric's longitudinal direction. A tensioning and locking mechanism (15, 16) is arranged to release or to lock the fabric bearing rod to rotate. Stabilizing brackets (14) secure the supporting legs (13) in at least one tilting angle. The tensioning and locking mechanism (15, 16) is operable to tension and to hold the collecting fabric (11) in a flat, tensioned shape when in the locking state so as to provide a receiving desk for the printed product. Further, the collecting fabric (11) forms a collecting bag when unreeled from the fabric bearing rod.
Supply device for roll medium and recording device
A supply device for a roll medium includes a drawer-type lower holding unit configured to support a shaft of a roll medium to hold the roll medium, and a guide member configured to be pressed in a direction toward the shaft from below to come into contact with the roll medium held by the lower holding unit, and be displaced in accordance with a change in an outer diameter of the roll medium. In addition, the lower holding unit is configured to be drawn from a main body of the supply device in a first direction. When the lower holding unit, in a drawn-out state, is stored in the main body of the supply unit, the guide member comes into contact with the roll medium. The guide member is caused to be retracted downward from a travel path of the lower holding unit against a force pressing upward from below.
CONVERTIBLE PRINTED PRODUCT COLLECTING ASSEMBLY
A convertible printed product collecting assembly includes a rotatable first rod connected to a printer, a second rod, a collecting fabric having flexibility, the collecting fabric fixed between the rotatable first rod and the second rod, wherein the collecting fabric is to receive a printed product from the printer, and two supporting legs to tiltably connect between the printer and the second rod.
Media catchers
In an example, a media catcher may include a first frame member and a second frame member spaced away from the first frame member along a lateral direction, thereby defining a catcher width of the media catcher. Additionally, the media catcher may also include a device interface disposed at a top end of the first frame member or the second frame member. The device interface may attach the media catcher to an imaging device. The media catcher may further include a catch panel extending between the first frame member and the second frame member to catch and support media.
Transport device, recording device, and medium transport method
A control device of a transport device includes a control unit configured to control a roll motor for rotating a first rotary shaft on which a medium is held and a transport motor for rotating a first driving roller, a tension detection unit configured to derive, for each tension detection cycle, a detected tension value of a tension applied to a tension adjustment portion of the medium, and a tension F/B unit configured to calculate a tension F/B correction amount by feedback control based on a deviation between a target tension and the detected tension value. The control unit is configured to calculate a driving force by the roll motor based on the tension F/B correction amount, and control the roll motor based on the driving force.
PROCESSING DEVICE AND RECORDING DEVICE
A recording device as a processing device includes: a recording unit accommodated in a housing and configured to perform recording on a medium; and a medium accommodating unit that accommodates the medium discharged from the housing. The medium accommodating unit includes: a sheet-shaped accommodating member; a rotating shaft provided inside the housing and to which one end of the accommodating member is connected; and an operating portion provided separably from the housing and to which the other end of the accommodating member is connected. The accommodating member is wound around the rotating shaft and accommodated inside the housing when the operating portion is mounted on the housing. The accommodating member is fed from the rotating shaft so that the medium is accommodated when the operating portion is separated from the housing.
SHEET FEEDING DEVICE AND PRINTING APPARATUS
A sheet feeding device includes a drive unit that rotates a roll of a wound sheet in a first direction and in a second direction, a sensor having an output which changes according to a distance between a detecting position facing a peripheral surface of the roll and the peripheral surface of the roll, and a control unit that determines an amplification factor of the sensor on the basis of data. The data is acquired by changing the amplification factor while the roll is rotated once in the second direction and includes a plurality of the output value acquired at different rotation angles.
WEB MEDIUM ORIENTATION DETECTION
In a method for high speed printing of web-based media, a medium is pulled along a media transport path to a pulling transport mechanism. The orientation of the medium with respect to the media transport path is sensed and this orientation is compared to a reference orientation to detect an orientation error. If an orientation error is detected, one or more of the following steps is performed: adjusting a print job for an image to be printed on the web medium; adjusting the transport speed; emitting a communication signal; and stopping the pulling transport mechanism and the image forming unit. It is the insight of the inventor that productivity may be increased by allowing a “tight winding” printing system to start printing at relatively high speed and reduce this speed only when significantly large deviations in the orientation of the web are detected.
METHOD FOR CONTROLLING A WEB IN A PRINTING APPARATUS
A method is provided for controlling a web in a printing apparatus The printing apparatus includes a transport assembly for moving the web through a transport path along a printing unit for printing an image onto a print area of the web. The method includes feeding the web from a supply roll through the transport path to the transport assembly; and switching the printing apparatus to a ready-to-print mode, wherein the printing unit does not print an image on the web and the web is maintained ready to be printed on. In a printing mode after the ready-to print mode, the following steps are performed: moving the web through the transport path in a transport direction along the printing unit by the transport assembly; and printing the image onto the print area of the web by the printing unit. The image is printed by applying an image material, which solidifies on the web during the printing step. The ready-to-print mode includes the step of: operating the transport assembly to prevent a deformation of the print area of the web in the transport path, while maintaining the web in the ready-to-print mode. The web is maintained ready to print while preventing a deformation of the print area of the web in the transport path.
PRINTER AND TRANSPORT APPARATUS
A pinion gear is coaxially attached to vicinity of an end of an inner bar. The pinion gear is engaged with a rack gear and rotates in response to upward and downward movements of the tension bar. When the pinion rotates, the inner bar correspondingly rotates. The inner bar and an outer bar, which is a tension applying bar, are connected to each other so as to freely rotate. When the pinion rotates, the inner bar correspondingly rotates, while the outer bar remains unrotated.
