  • Patent number: 7150455
    Abstract: In order to accurately maintain an interval between a preceding sheet and a subsequent sheet, a sheet conveying device effects control such that, under the condition that a trailing end sensor disposed on a conveying path for supply has detected a trailing end of the preceding sheet, the subsequent sheet is conveyed at a high-speed conveying speed at a fixed time, and such that, under the condition that a leading end sensor has detected a leading end of a sheet, switches a detected sheet from the high-speed to a low-speed conveying speed at a fixed time and conveys the detected sheet.

  • Patent number: 6145830
    Abstract: A sheet material supplying apparatus having a low-cost sucker adsorbing unit of a simple structure is provided for the carrying of sheet materials that are used under a high-humidity environment or that include humidity, to ensure a proper separation of each sheet material. Sheet materials accommodated in a tray are being sandwiched between a push-up panel and an engagement claw. At the time of taking out the sheet materials from the tray, the push-up panel is pressed down by a cam to cancel the state of sandwiching between the engagement claw and the push-up panel. Accordingly, only the top layer sheet material is taken out from the tray, with the rest of the lower layer sheet materials being dropped by their self-weight. Further, the sheet materials are carried by the sucker adsorbing unit.

  • Patent number: 6115106
    Abstract: An image recording apparatus, in which a necessary place can be suitably exposed by simple operation and the workability of inspection, maintenance and the like improves, is obtained. In the image recording apparatus, an upper cover is rotatably connected to and supported at a base stand by an intermediate hinge. Accordingly, there are a first stage opened/closed state, in which the upper cover opens and closes around a supporting shaft, and a second stage opened/closed state, in which the upper cover integrally opens and closes along with the intermediate hinge around another supporting shaft. In the second stage opened state, the inner portion of the base stand is exposed by a large amount, the distal end portion of a stage is lifted, and further, the holding of a supply magazine and a take-up magazine is released. As a result, the innermost place within the apparatus is exposed and the workability of inspection and maintenance, such as replacement of the supply magazine or the take-up magazine, improves.

  • Patent number: 5649269
    Abstract: An image recording apparatus is designed to decrease the size of an exposure unit, thereby allowing the exposure unit to move within a narrow space between an original document and a photosensitive material, to facilitate color adjustment and density adjustment, to provide a high resolution at low costs, and to prevent light fogging. The exposure unit is moved between a stage and a document table which hold a photosensitive material and an original document, respectively, so as to copy the image of the original document onto the photosensitive material by scanning exposure. An LED light source comprises three groups of light emitting elements which respectively emit blue, green and red colors, and a light beam from the LED light source is irradiated such that the light beam extends in a direction parallel to the original document and perpendicular to the direction of movement of the exposure unit (the forward and backward direction of the stage).

  • Patent number: 5625856
    Abstract: An image forming solution applicator which is formed of a flexible, porous material, and which can absorb and hold an image forming solution supplied from an external portion, and from which absorbed and held image forming solution flows out due to the applicator contacting an image recording material, and which applies the image forming solution to the image recording material by moving while contacting the image recording material. An average porosity of a portion of the applicator to which the image forming solution is supplied is greater than an average porosity of a portion of the applicator which contacts the image recording material. Accordingly, supplied image forming solution smoothly penetrates into the applicator, and is quickly absorbed and stably retained by the applicator.
