Abstract: A finisher connected to a copying machine produces a bound booklet by inserting papers from the copying machine into a cover with an adhesive layer of a hot-melt adhesive which is coated on the inner surface of near a spine interconnecting a front board and a back board, and heating the cover and a sheaf of papers, and joining them by adhesion. Thus, the series of operations ranging from the preparation of documents through the bookbinding can be facilitated and expedited.

Abstract: A finisher comprising a non-sort tray disposed at an uppermost location, a stacking tray for stapling disposed at an intermediate location, and a large-capacity storing tray disposed at a lower location. In a non-sort mode, sheets discharged from a copying machine are first stored in the non-sort tray and, when the non-sort tray is occupied full, subsequent incoming sheets are stored in the storing tray. In a stapling mode, sheets are collected on the stacking tray and, after a stapling operation, they are stored in the storing tray.

Abstract: A finishing apparatus comprising a transport section for transporting sheets discharged from a copying machine, a tray for stacking sheets thereon, and a finishing section for transporting a set of collected sheets from the tray and for stapling the sheet set. Folding rollers for folding a sheet in two or centrally folding the sheet are provided in a sheet transport section. Sheets, in a two-folded condition or with a center fold line formed thereon, are discharged onto the tray. Sheets which have been centrally formed with the fold line are subjected to stapling on or along the fold line.

Abstract: An LSI chip has Al bumps transferred from an Al-containing foil and formed thereon by ultrasonic bonding. The LSI chip is thereafter mounted on a circuit board by an adhesive containing fine metallic particles dispersed or arranged uniformly, an insulative adhesive with high fluidity or ultrasonic bonding.

Abstract: A sheet storing apparatus wherein sheets ejected from a copying machine one after another are stacked in order, and the sheets are supplied to the copying machine again. The apparatus comprises a sheet storing unit wherein sheets are stored, a transporter for transporting sheets to the storing unit, a regulator for preventing sheets supported by a sheet support surface of the storing unit from moving back toward the entrance thereof, a pressure member for pressing each sheet transported to the unit against the support surface and a refeeder for feeding out the stored sheets one by one. Each time a sheet is transported to the unit, the pressure member presses the sheet, whereby the end of the sheet passes through the regulator to be put between the support surface and the regulator. Also, in feeding sheets out of the unit, the pressure member presses the sheet stack against the refeeder.

Abstract: A sheet transporting apparatus comprising an outlet for sheets, a first path through which sheets ejected from a copying machine are transported in a first direction, to the outlet and in a second direction to be reversed from the outlet, a diverter for diverting the travel of sheets, which is disposed in the vicinity of the outlet and movable between a first position where sheets traveling in the first direction are guided to a handling apparatus attached at the outlet and a second position where sheets are guided to a space between respective outside frames of the transporting apparatus and the handling apparatus, a second path for receiving sheets traveling in the second direction along the first path and transporting the sheets, a storing unit wherein sheets transported through the second path are stored and a refeeding section for feeding sheets stored in the storing unit to the copying machine.

Abstract: A copy sheet stack apparatus stacks copy sheets discharged from an image-forming device and binds them be means of a staple. The apparatus comprises a first accommodating device for accommodating copy sheets discharged from the image-forming device, a staple device for binding by way of the staple the copy sheets accommodated into the first accommodating device, a second accommodating device disposed below the first accommodating device to accommodate a bundle of the copy sheets bound be means of the staple, a fall device for making the bundle of the copy sheets bound by way of the staple fall from the first accommodating device to accommodate into the second accommodating device by its own weight, and a guide device disposed between the first accommodating device and the second accommodating device to guide the bundle of the copy sheets fallen from the first accommodating device to the second accommodating device.

Abstract: A sheet handling apparatus comprising a stapling tray for receiving sheets ejected from a copying machine and a stamp for stamping on the sheets in the stapling tray, wherein the surface of the stapling tray facing the stamp is made of soft and elastic material to reduce friction.
