  • Patent number: 6320642
    Abstract: A cooling section 400 for cooling a recording material A, which is a recording material, is disposed in a downstream portion of a heat development section 18. The cooling section 400 has a pair structure consisting of a metal roller 404 and a roller 402 made of an elastic material. The metal roller 404 having excellent heat conductivity is brought into contact with an image forming surface of the recording material A. As a result of the foregoing structure, the recording material A subjected to the heat development can uniformly be cooled to a temperature not higher than a development interruption temperature during conveyance in the cooling section 400. The metal roller may be modified variously. For example, the metal roller is cooled by a cooling mechanism or replaced by a belt.

  • Patent number: 5427365
    Abstract: Sheets such as photographic films are fed, one by one, from a stack of sheets on a sheet support to a sheet delivery mechanism. Suction cups for attracting an uppermost sheet of the stack are moved toward the stack, and activated to attract the uppermost sheet. The suction cups are then moved to remove the uppermost sheet from the stack while the suction cups are being inclined a predetermined angle from a direction perpendicularly to the uppermost sheet toward opposite to a direction in which the sheet is fed. The removed uppermost sheet is then transferred to the sheet delivery mechanism in the direction in which the sheet is fed.

  • Patent number: 5295673
    Abstract: Photographic light-sensitive mediums such as sheets are fed one by one by a suction pad in a sheet-feed control device. The suction pad is displaced downward at a low speed in a position near a stack of sheets so as to approach an uppermost one of the sheets, thereby attracting the uppermost sheet to the suction pad, and the uppermost sheet is flexed by a sheet presser while it is being separated away from the other sheets. Then, a judgement is made as to whether the suction pad attracts either a single sheet or a plurality of sheets, by detecting the magnitude of the flexion of the sheet or sheets attracted. Then, the suction pad is displaced again toward the position where the uppermost sheet is to be attracted, when it is detected that the suction pad has attracted the plurality of sheets. At this time, the suction pad is placed in a given stop position, thereby releasing the plurality of sheets from the suction pad.

  • Patent number: 5257776
    Abstract: Sheets such as photographic films are fed one by one by suction cups in an image recording system. A resilient sheet separator is brought into abutment against an uppermost one of stacked sheets, and then the suction cups are moved toward the uppermost sheet. Before the suction cups reach the uppermost sheet, they are activated to attract the uppermost sheet under suction. The sheet separator pushes the uppermost sheet in one direction and the suction cups draw the uppermost sheet in the opposite direction, so that the attracted uppermost sheet is greatly flexed fully out of contact with the next sheet of the sheet stack. Thereafter, the suction cups and the sheet separator are displaced away from the sheet stack, separating the uppermost sheet from the sheet stack. A detecting arrangement detects whether the suction cup attracts a single sheet.

  • Patent number: 5183241
    Abstract: Disclosed herein is a device for feeding sheets one by one. This device basically comprises a suction pad moved toward stacked sheets so as to attract an uppermost sheet of the stacked sheets thereto, a drum rotatable in both forward and reverse directions, a first belt-type conveying system disposed on one part of the surface of the drum, a second belt-type conveying system disposed on another part of the surface of the drum, a sheet insertion port defined by the drum and the first belt-type conveying system, and a sheet withdrawal port defined by the drum and the second belt-type conveying system. The device is also characterized in that the suction pad is displaced to face the sheet insertion port so as to interpose the uppermost sheet between the drum and the first belt-type conveying system, followed by transfer toward the second belt-type conveying system, and the uppermost sheet is reversed by the drum and the second belt-type conveying system so as to be discharged from the sheet withdrawal port.

  • Patent number: 5180156
    Abstract: Disclosed herein is a method of feeding sheets. The sheets such as photographic photosensitive films are fed one by one by a suction pad in an image recording apparatus. The suction pad is displaced at a higher speed toward a stack of sheets, and then the speed of the suction pad is reduced to cause the suction pad to approach the stacked sheets ata lower speed. It is thereafter detected whether or not an uppermost one of the stacked sheets is attracted by the suction pad. Further, the suction pad is stopped from being moved toward the stacked sheets immediately upon detecting that the suction pad has attracted the uppermost sheet, and is also displaced away from the stacked sheets until the suction pad reaches a desired position.

  • Patent number: 5127645
    Abstract: A sheet feed control system for use in an image recording apparatus, for example, includes a suction cup for attracting a sheet-like member such as a photographic film under suction, a crank mechanism for moving the suction cup with respect to the sheet-like member, and a swinging mechanism for swinging the suction cup with the sheet-like member attracted thereto to impart swinging action to the sheet-like member. The crank mechanism is drived by a pulse motor in response to a control signal applied thereto, and the swinging mechanism is drived by a pulse motor in response to a control signal applied thereto. Information, such as rotational speeds and angular displacements, with regard to the pulse motors is stored in a memory, and desired information corresponding to certain physical properties of the sheet-like member, can be selected from the memory by the operator.
