Abstract: In a sheet discharge mechanism for enabling a wide range of sheets stored on a sheet discharge tray from a processing section, a brake lever for reducing a velocity of a sheet fed from a sheet discharge outlet is held detachably relative to an attachment frame above the sheet discharge tray, and it is possible to select whether brake action is made corresponding to sheet discharge conditions. A sheet discharge mechanism includes a sheet discharge path having a sheet discharge outlet, a sheet discharge tray disposed on the downstream side of the sheet discharge outlet with a level difference, and a brake section of a sheet carried out at the sheet discharge outlet, wherein the brake section includes a lever member in which its base end portion is axially supported by an attachment frame, and its front end portion moves up and down corresponding to a load amount of sheets.

Abstract: To provide an illumination device in which there is no variation in light intensity distribution of the illumination device, and in which illumination spots, particularly light intensity spots, are not prone to occur in a read image in an image reading device, by maintaining a constant gap between a light source and an end face of a light guide. The illumination device includes: a light guide having an end face for taking in light, a diffuse reflecting surface for diffusely reflecting the light taken in from the end face, and a light exit surface for emitting the light that is diffusely reflected at the diffuse reflecting surface towards an irradiation surface. The illumination device further include a reflector having a diffuse reflecting surface that reflects light from the light source toward the one end face of the light guide.

Abstract: The present invention prevents units from becoming unbalanced and falling over when an image-capturing unit is opened over an image-forming unit when an image-forming unit, image-capturing unit and document-feeding unit are stacked over each other in order. The image-capturing unit is rotatably linked to the top of the image-forming unit by a first hinge means, and the document-feeding unit having document-feeding means is rotatably linked to the top of the image-capturing unit by second hinge means. Locking means for checking rotation (opening operation of the document-feeding unit) of the second hinge means is disposed on an opposite side of the second hinge means sandwiching the document-feeding means. The locking means is composed to check the opening operation of the second hinge means when the first hinge means is opened.

Abstract: Provided is a traveling unit driving apparatus where a driving belt of the traveling unit is manufactured with ease, and concurrently therewith, can be coupled reliably to the unit in a state with high durability. A driving belt extended between a pair of pulleys is formed using a belt with ends and teeth, and a belt fixing means is comprised of a first and second engagement portions provided in the traveling unit, a concave recess portion disposed between the portions, and a lock fixing member that is fitted into the concave recess portion. Then, the first and second engagement portions and the concave recess portion are provided with a first and second mount surfaces for bending and supporting the belt opposite end portions, the lock fixing member is fitted into the concave recess portion, and the belt opposite end portions are thereby sandwiched and held in a bent state.

Abstract: To enable accurate image reading and concurrently therewith, enable a reading optical system to be varied easily in an apparatus configuration in which first and second read portions are disposed in planes inclined a predetermined angle, the apparatus has an apparatus housing 10, a platen 11 disposed in the apparatus housing to form the first read portion 11a and the second read portion 11b in planes mutually inclined a predetermined angle, a reading carriage 12, 40 disposed to be able to shift to positions between the first read portion and the second read portion, and a light source lamp 15, 41 for applying light to a document sheet on the platen, and a reflecting mirror 16, 42 for guiding the reflected light from the document sheet toward image reading means 13 each mounted on the reading carriage, and is configured so that an angular attitude of the reflecting mirror 16 is deflected by a predetermined angle or deflecting means 46 disposed in the second read portion guides the reflected light to the reflec
