摘要:
A developer supply device for supplying an image forming apparatus with a developer includes a developer accomodating container having an opening for supplying the developer, and a member for opening and closing the opening of the container. The developer accomodating container is slid to be positioned at a predetermined position. The direction of movement of the openable and closable member to open the opening coincides with the direction of the sliding movement for being positioned. A force needed for the movement of the openable and closable member is arranged to be larger than a force needed for the sliding movement of the developer accomodating container. The device also includes a regulating member, which prevents the developer accomodating container from being moved from the predetermined position when the openable and closable member is opened. In order to prevent mismounting of an improper developer accomodating container, engagement between the developer accomodating container and a mounting portion for the container is arranged to be different in accordance with the kind of the developer.

An ink jet textile printing apparatus for performing printing by reading an original image created by a designer, converting the original image into original data represented by an electric signal, retrieving the original data for processing to be output as image data, and recording data on cloth based on the image data. The ink jet textile printing apparatus has a first ink jet recording head provided upstream of a recording position, and a second ink jet recording head provided downstream thereof, and is provided with a drying unit located between the recording heads, whereby high-quality recorded images with less bleeding can be obtained by recording on a recording area again with the second ink jet recording head after drying the recording area on the cloth recorded by the first ink jet recording head with the drying unit.
摘要:
Disclosed is a recording apparatus that includes a conveying device for conveying a recording sheet in a conveying direction, a recording device confronting the conveying device for recording an image on the sheet being conveyed and a supporting device for shiftably supporting at least one of the conveying device and the recording device for movement between a recording position where the conveying device and the recording device are in parallel contact with the recording sheet therebetween and a non-recording or separated position where the conveying device is separated from the recording device. In one embodiment, the recording device and the conveying device are separated in parallel in the non-recording position and the supporting device causes the at least one of the conveying device and the recording device to be non-parallel during movement from the non-recording position to the recording position. In another embodiment, during movement of the conveying device from the separated position to the recording position, the supporting device first causes a first end of the conveying device to obliquely shift towards the recording device and thereafter, causes a second end of the conveying device to shift toward the recording device.
摘要:
A cleaning method for removing a recording ink from a surface of a recording material conveying belt of a recording apparatus. The method includes the steps of detecting a recording material jam; press contacting a cleaning member to a surface of the recording material conveying belt in response to the detected jam, thus removing from the belt surface an improper discharge of recording ink; and separating the cleaning member from the surface of the conveying belt after cleaning for a period of time. The period of time is determined based upon an amount of the recording ink discharged onto the conveying belt surface.

In a support device for a direct drive electric motor found in apparatuses such as copy machines, printers, etc., employing the method of driving a driven shaft by an output shaft of the motor in direct connection thereto, the motor body is supported by the direct connection of the output shaft of the motor with the driven shaft, and a rotation preventing plate is provided for preventing the motor body from rotating about its output shaft, as the rotation preventing plate is in engagement with a fixed member.
摘要:
A recording apparatus builds an image at high quality without occurrence of malfunctions attributable to raised/recessed spots on the surface of a conveyance belt and insufficient dimensioning for the width of the conveyance belt, while preventing the interior of the recording apparatus from being contaminated with erroneously ejected ink. The recording apparatus includes a conveyance belt for conveying a recording sheet below four kinds of recording heads, and the conveyance belt has a joint line along which the opposite ends of a band-shaped material are joined to each other. In addition, the conveyance belt has a band-shaped colored portion which is located remote from the joint line by a predetermined distance. The colored portion is detected by an optical sensor, and a control unit controls the driving of the conveyance belt in response to a signal derived from the detection of the optical sensor.
摘要:
A belt driving apparatus for carrying material to be recorded to a plurality of image recording units. In the belt driving apparatus, the distance of movement of material to be recorded corresponding to one rotation of the belt driving roller has been set to n (an integer)-times (where n=2, 3, 4 . . . ) as long as a distance between each image recording unit. A distance between one image recording unit and another recording unit is equal to or an integral fraction of .pi.(D+2 t), wherein D is the diameter of a drive roller driving the belt and t is the thickness of the belt.
摘要:
The present invention provides a recording apparatus comprising a conveyor for conveying a sheet while contacting therewith, a recording device for recording an image by discharging ink onto the sheet conveyed by the conveyor, a cleaning device for sweeping the ink adhered to the conveyor by slidingly contacting therewith, and an absorbing member for absorbing the ink adhered to the conveyor.
摘要:
A transport device for use in a recording apparatus is disclosed. The transport device includes a conveyor belt having at least three layers. The upper layer of the belt is a conductive or semiconductive layer that is discriminable from a recording material by a detector. Below the first conductive or semiconductive layer is an insulating layer and below the insulating layer is a third conductive layer. The first layer has a volume resistivity value of from 10.sup.14 to 10.sup.17 .OMEGA.cm. The detectors are positioned upstream and downstream of the recording region and disposed downstream of that recording region is a cleaning blade and absorber which together work under control of a controller to clean ink from the conveyor before it soils the charging roller or the next recording sheet. The controller also controls the cleaning operation in accordance with the amount of ink that was unnecessarily jetted onto the conveyor belt.
