Abstract:
A multifunction printer having a compact size and portable configuration while providing printing, scanning and copying functionalities is disclosed. The multi-function printer may include a paper handling assembly and a floating scanner assembly pivotably coupled to the paper handling assembly. The multi-function printer may further include a printer assembly coupled to the paper handling assembly. The floating scanner assembly is coupled to and aligned with a pick roller portion of the paper handling assembly and configured to scan and/or otherwise operate on a media supported within a document feeder. Thus, the multi-function printer may provide a wide variety of functionalities while maintaining a desirable compact configuration and portability.
Abstract:
A contact-type image sensor having an adhesive elastic layer therein includes a protective member including a light transmitting area. An illumination device is provided for illuminating an original, bearing image information thereon, through the protective member. A photosensor device is provided for reading the image information, and imaging structure is provided for focusing light reflected from the original onto the photosensor device. Support structure is provided for integrally supporting the illumination device, the photosensor device, and the imaging structure. An elastic adhesive layer is provided on a contact surface between the protective member and the support structure. The elastic adhesive layer joins the protective member and the support structure.
Abstract:
The improved transporting apparatus for scanning exposure of a recording material as it is fixed on an exposure mount which is moved by means of a screw transmission mechanism is characterized in that the exposure mount for transporting the recording material is composed of a platen for carrying the recording material and a transport plate that holds the platen and which engages the screw transmission mechanism, with the platen and the transport plate being designed to be capable of relative displacement by small amounts, preferably in a non-contact relationship. Optionally, urging members may be provided to combine with the platen and the transport plate to form a vibration system that composes a vibration filter. The apparatus effectively absorbs not only vibrations that originate from the drive system to be transmitted to the exposure mount via the travelling nut of the screw transmission mechanism, as exemplified by erratic rotation or vibrations of the motor and the screw shaft of the screw transmission mechanism, but also vibrations due to externally applied forces and, hence, highly precise scanned transport of the recording material can be accomplished while suffering from very small levels of unevenness in the speed of its transport that will occur on account of those unwanted vibrations.
Abstract:
In one of aspects of the invention, an automatic sheet conveying mechanism comprises upper and lower casings mutually coupling sheet conveying paths in a releasable state, and a sheet guide plate for partitioning the sheet conveying paths together with the lower casing, guiding the lower surface of the sheet being conveyed, and defining the projecting extent of the functional parts supported by the lower casing into the sheet conveying path, in which the sheet guide plate is formed integrally with the lower casing.
Abstract:
An image-reading device comprises a lens unit array comprising an array of distributed refractive index plastic cylindrical lens elements and plastic plates, adhering the distributed refractive index plastic cylindrical lens elements therebetween, and a plastic case containing and holding the lens unit array. The difference in the thermal expansion coefficients of the plates of the lens unit array and the plastic case is 5.0.times.10.sup.-5 cm/cm/.degree. C. or below, or more preferably, 3.0.times.10.sup.-5 cm/cm/.degree. C. or below. The plastic case is formed by connecting, in a longitudinal arrangement, a plurality of case segments formed by an injection molding.

Abstract:
There is disclosed an image ssensor unit comprising: illumination unit for illuminating light on an original; an image sensor for reading out image information on the original by reflection light of said illuminated light; holding for holding the illumination unit; and a mounting unit for causing the holding unit to hold the illumination unit so that the relative displacement between the illumination unit and said holding unit in a direction along a surface of the holding unit on which the illumination unit is held by the holding unit.
Abstract:
An image reading apparatus includes: a contact glass setting a manuscript thereon; an image sensor extending in a first direction and having a reading surface which faces the contact glass for reading an image from the manuscript on the contact glass; a rail member extending inside the apparatus main body in a second direction perpendicular to the first direction; a carriage having a sensor container to contain the image sensor, a taper end portion formed in an end portion in the first direction to become smaller in height toward the end side, and an opening formed in the bottom of the sensor container on the taper end portion side; a biased portion adjacent to the reading surface of the image sensor in the second direction; and a biasing member biasing the image sensor toward the contact glass via the biased portion.
Abstract:
An automatic sheet conveying mechanism comprising an automatic document conveying mechanism and having a sheet guide plate (102) defining an opening (P9b) for receiving an elongate contact type image sensor (109) for scanning a lower surface of a document conveyed in a sheet conveying path (103) and guiding said lower surface of said document. The sheet guide plate (102) is integrally formed with an accommodating part (102c) for accommodating the image sensor (109) in a predetermined position, and the opening (P9b) is dimensioned to enable the image sensor to be put in and taken out of said accommodating part (102c) from above said sheet guide plate (102).
Abstract:
An image sensor has a supporting member for integrally supporting a reading system including illuminating means for illuminating an original document, a photoelectrically converting means and imaging means for imaging light reflected by the surface of the original document onto the photoelectrically converting means, and has a member disposed on the side surface of the supporting member. The image sensor has two or more substantially independent spaces formed in the supporting member. The illuminating means, the imaging means and the photoelectrically converting means are accommodated in one of the spaces.
