Abstract:
An image forming system includes: an image forming mechanism configured to form an image on a sheet of a transfer material; a post-processor configured to perform post-processing on a plurality of sheets of transfer materials, respectively, there being on at least one of which a respective image has been formed by the image forming mechanism; a transporter to transport the sheets through the post-processor along one or more transport paths; and a controller operable to do the following including, determine a first stopping condition of whether the number of sheets exceeds a reference number, and detect a second stopping condition of whether a cumulative thickness of the sheets loaded in the post-processor exceeds a reference thickness, and stop further image formation by the image forming mechanism when at least one of the first and second stopping conditions is satisfied.
Abstract:
A paper perforating apparatus which can securely prevent a paper end portion from being caught in a punch hole, without having an assist member, such as mylar, in a paper finisher which comprises a perforating device capable of moving in a direction perpendicular to the paper conveyance direction, the paper perforating apparatus, comprising: a paper conveyance device for conveying a paper; a perforating device for perforating the paper; a paper end portion detecting device for detecting an end portion parallel to the conveyance direction of the paper; and a device for moving the perforating device in a direction perpendicular to the conveyance direction, wherein the paper perforating apparatus offsets a standby position of the perforating device, which is in the direction perpendicular to the paper conveyance direction, from a position in which holes are punched out on the paper by a predetermined distance, and the perforating device starts operation of perforation preparation from the standby position after being passed by a front end of the paper.
Abstract:
An ink-receiving layer has a bilayer constitution, which is formed by sequentially laminating a lower layer and an upper layer on a support. The upper layer contains alumina having an average pore diameter of less than 5 nm (alumina A) and alumina having an average pore diameter of 5 nm or more (alumina B) in a weight ratio of (alumina A):(alumina B)=100:0 to 70:30; the lower layer contains the alumina A and the alumina B in a weight ratio of (alumina A):(alumina B)=0:100 to 50:50; and the thickness ratio of the upper layer to the lower layer is as follows: (upper layer):(lower layer)=2:1 to 5:1.
Abstract:
A sheet finisher for performing preselected processing with a sheet or a sheet stack conveyed thereto of the present invention includes a cutter unit configured to cut the sheet or the sheet stack in a direction perpendicular to a direction of sheet conveyance. A guide member is positioned upstream of the cutter unit in the direction of sheet conveyance for guiding the sheet or the sheet stack being conveyed. A moving device moves the guide member in a direction parallel to the direction of sheet conveyance.
Abstract:
A first storage control system comprises a CHN connected to a LAN CN. The CHN comprises a NAS processor and I/O processor. The I/O processor judges whether all or a portion of block level data is to be stored in either a first storage control system or a second storage control system, on the basis of an I/O allocation control data which indicates which of either the first storage control system or the second storage control system the block level data is to be stored in. On the basis of the result of this judgment, the I/O processor transfers the block level data from the NAS processor, to at least one of the DKA and the CHF connected to the second storage control system.

Abstract:
A sheet finisher for executing preselected processing with a sheet conveyed thereto of the present invention includes a first processing tray configured to temporarily store the sheet and deliver it. A first and a second path are positioned downstream of the first processing tray in a direction of sheet conveyance and configured to convey a first and a second sheet stack, respectively. The first path conveys the first sheet stack upward over the downstream portion of the first processing tray while the second path conveys it downward over the same. A switching device selects either one of the first and second paths. The sheet finisher of the present invention is low cost and highly productive and space saving.
