摘要： A facsimile apparatus includes a light emitting unit disposed downstream in the direction of feed of a document with respect to a normal plane perpendicular to the document surface on a reading line. Outgoing beams for reading travel rearward in a substantially horizontal direction. Incoming beams from the light emitting unit are reflected on the reading line on the document surface and are supplied as the outgoing beams for reading to a light sensing unit. Consequently, it is possible to reduce the height of the front portion of the facsimile apparatus so as to increase a degree of freedom in designing while enhancing reliability in reading the document.

摘要： A facsimile apparatus includes a main body frame, an operable cover plate for covering at least the front top of the main body frame, a separating roller for separating a document sheet attached to the main body frame and a document feeding mechanism for feeding a document sheet separated by the separating roller. All of the rollers in the document feeding mechanism are attached to the main body frame. Since all rollers of the document feeding mechanism are attached to the main body frame, it is not necessary that the cover plate have high rigidity. Consequently, the weight of the cover plate can be reduced, and the manufacturing cost of the cover plate can be reduced.

摘要： A facsimile machine has various detection devices. One of the detection device detects a sheet medium. The detection device includes a reflection type sensor directly mounted on a control board. An actuator is pivotally movably supported in a main frame of the facsimile machine. The actuator has a pivot shaft portion, a first arm and a second arm those extending from the pivot shaft portion. A free end of the first arm is abuttable on the sheet medium. If sheet medium is transferred to a predetermined portion, an edge of the sheet urges the free end to angularly rotate the actuator. A free end of the second arm is provided with a reflection member. The angular movement of the actuator causes the reflection member to be brought into confrontation with the reflection type sensor so as to detect passage of the sheet medium. A regulation member is integrally provided to the reflection member. The regulation member is brought into contact with the control board because of the gravity of the actuator, so that a given distance is provided between the reflection member and the reflection type sensor in the confronting state therebetween. The other sensor device may detects moving phase of a movable member. To this effect, the free end of the first arm is abuttable on the movable member.

摘要： A sheet conveying device includes a metal feed roller driven by a drive source and a plastic pinch roller pressed against the feed roller. A sheet is held between the feed roller and the pinch roller, to convey the sheet to a recording unit. An elastic ring having a high wear resistance is fitted over a part of an outer surface of the pinch roller in a width direction of the pinch roller. Accordingly, the elastic deformation of the elastic ring reduces or absorbs load (impact) that causes a rear end of the sheet to flick or spring and the improper sheet feeding, when the rear end of the sheet passes through a nip portion between the feed roller and the pinch roller. Thus, variances in the sheet feeding amounts and the poor image formation are prevented.

摘要： An image signal processing device 1 comprises an encoding part 10, a delay part 20, a difference calculation part 30, a decoding part 40, a quantization error determination part 50 and a corrected image data output part 60. The corrected image data output part 60 outputs image data G2 input to the encoding part 10 as corrected image data G2′ when a difference D output from the difference calculation part 30 is equal to or less than a predetermined value Dth, or determines a basic correction value from the image data G2 input to the encoding part 10 and decoded image data GB1 output from the decoding part 40, reduces the basic correction value by a value in accordance with the magnitude of a quantization error E determined by the quantization error determination part 50 to obtain a modified correction value, and outputs the image data G2 input to the encoding part 10, to which the modified correction value is added, as the corrected image data G2′ when the difference D is greater than the predetermined value Dth.
