Abstract: In an original pressing plate hinge including a fixing member, an original pressing plate supporting member pivotably installed via a hinge pin to the fixing member, a slider slidably housed in the supporting member, a cam member fixed between the slider and the free end of the supporting member in contact with the slider, and a coil spring provided resiliently between the slider and the free end of the supporting member, the cam member is omitted to prevent an original or document set on the platen glass for copying or printing from being stained with or spoiled by a lubricant when the original touches the cam member to which the lubricant sticks, and instead a pressure receiving pin is used and a cam slider is used in place of the slider. To prevent a heavy original pressing plate from abruptly falling, a fluid damping member is housed in the coil spring and disposed between the cam slider and the top plate or free end of the supporting member.

Abstract: Original cover closer with mounting base and supporting member has bent side plates rotatably mounted to each other. A lifting member with document pressure plate has side plates mounted to the supporting member side plated enabling the lifting member side plates to rotate in a different direction. A pressure bearing pin is mounted between the mounting member side plates and a cam slider is in the supporting member with a cam part in contact with the pin. A spring between the slider and the lifting member urges the supporting member to open the original cover while urging the lifting member in a direction overlapping the supporting member.

Abstract: In order to eliminate the cam member, which is mounted to the mounting member side and to which grease is applied, to prevent, as much as possible, the portions to which grease has been applied from becoming exposed to the side of an original placed on the contact glass, an original cover closer is arranged from a mounting member, which has a mounting base and side plates, which are raised from both sides of the mounting base, and has the abovementioned mounting base mounted to the main device unit side, a supporting member, which supports an original cover, has a back plate as well as side plates and a top plate, which are bent from the back plate, and has one end of each of the side plates being rotatably mounted via a hinge pin to the corresponding side plate of the abovementioned mounting member, a cam slider, which is fitted inside the supporting member in a manner enabling sliding towards the side of the abovementioned mounting member, a pressure bearing pin, which is axially mounted between the respect

Abstract: In an original pressing plate hinge including a fixing member, an original pressing plate supporting member pivotably installed via a hinge pin to the fixing member, a slider slidably housed in the supporting member, a cam member fixed between the slider and the free end of the supporting member in contact with the slider, and a coil spring provided resiliently between the slider and the free end of the supporting member, the cam member is omitted to prevent an original or document set on the platen glass for copying or printing from being stained with or spoiled by a lubricant when the original touches the cam member to which the lubricant sticks, and instead a pressure receiving pin or roller is used and a cam slider is used in place of the slider. To prevent a heavy original pressing plate from abruptly falling, a damping member is housed in the coil spring and disposed between the cam slider and the top plate or free end of the supporting member.

Abstract: An original-cover closer has: a mounting or base member to be installed on the body of a copying machine; a supporting member pivoted at side plates thereof by a first hinge pin to side plates of the mounting member and on which an original cover is supported and; a lifting member mounted at side plates thereof by a second hinge pin on the supporting member at free ends of the side plates thereof to be pivotable in an opposite direction to the direction in which the support member is opened and closed and to which the original cover is to be fixed.

Abstract: A pallet is made of a substantially rectangular corrugated fiberboard, so that it has a loading surface region, two end cleats extended from two edges of the loading surface region which are in parallel with the longitudinal axis of the corrugated fiberboard, and at least one V-shaped supporting beam formed at each end of the lower surface of the loading surface region. A bottomless corrugated fiberboard container is placed on the pallet in such a manner that the lower end portion of the container is between the end cleats. The lower end portion of the container is bonded to the end cleats, or is detachably secured to the end cleat, so as to form a packaging box wherein a separable pallet forms the bottom of the box.

Abstract: An escape chute made up of a framework which can be horizontally projected outward from a building; a double tubular body having an inner cylinder and an outer cylinder made of cloth, and a spiral slide cloth forming a slide surface which is fixed between the inner cylinder and the outer cylinder; an upper entrance at the top and an exit at the bottom; one or more intermediate access apertures and intermediate entrance passages made of cloth to permit entrance into the space between the inner cylinder and the outer cylinder wherein the height of the lower edge of the intermediate access aperture is higher than the spiral slide surface at the position so as to prevent a part of a person from becoming hung up upon the aperture.The intermediate entrance passages are held by ropes connected to the framework.One or more intermediate exits are formed on the side surface of the bottom outer cylinder at higher than the exit.
