A radiographic image erasing device includes: a first light source that applies first erase light including a wavelength in the ultraviolet region to a storage phosphor sheet in which a radiographic image has been stored and recorded; a second light source that is placed at a height identical to that of the first light source and applies second erase light including a wavelength of a longer wavelength than that of the first erase light to the storage phosphor sheet to which the first erase light has been applied; drive mechanisms that switch the orientations or positions of the first light source and the second light source; and a controller that controls the drive mechanisms in accordance with a conveyance direction of the storage phosphor sheet such that the first erase light and the second erase light are applied in this order to the storage phosphor sheet.

In a sheet sucking/feeding device, actuators are independently and individually connected respectively to plural suction cups. At a point in time when a printing plate is sucked and raised up by a predetermined amount, every other one of the actuators is simultaneously operated such that the suction cups connected to the operated actuators are displaced upwardly. The sucked uppermost printing plate is curved so as to become wavy. Air enters in between the uppermost printing plate and a next printing plate therebeneath such that that printing plate therebeneath is disjoined (separated). Only the uppermost printing plate is stably removed and fed out.

A planographic printing plate supply unit comprising: carrying rollers rotating while pressing a stacking bundle, in which planographic printing plates and covering papers are stacked alternately, so as to carry the planographic printing plate and covering paper at the top of the stacking bundle, wherein convex portions which are elastically deformed when pressing the stacking bundle and whose contact area with the planographic printing plate is larger after being elastically deformed than before are provided on the outside periphery of the carrying roller.

A printing plate sucker capable of stably suction-adhering and sheet-feeding both a printing plate and a protective sheet simultaneously without causing wrinkling at the protective sheet during the suction-adherence and sheet-feeding. The sucker is structured by a main body portion formed of a stiff body, a skirt portion formed of a resilient body, and a spring. When a moment from a printing plate acts on the sucker during sheet-feeding, the spring resiliently deforms. Thus, the main body portion is displaced (inclined) in the moment application direction, effective weight on the sucker is reduced, and a state in which a reduced moment acts on the sucker is achieved (the moment is substantially absorbed). Furthermore, the spring which redirects the moment is structured separately from the main body portion and skirt portion. Therefore, the sucker will not be deformed, an interleaf sheet will not be hoistingly deformed, and wrinkling will not occur.

A conveying device has: a moving member provided so as to be movable; a rotating member rotatably supported at the moving member; and a holding member rotatably supported at the rotating member, and able to hold a sheet. In a state in which the holding member is holding the sheet, the holding member conveys the sheet by at least one of movement of the moving member, rotation of the rotating member with respect to the moving member, and rotation of the holding member with respect to the rotating member.

Conveying device

A conveying device for a printing plate precursor which takes the printing plate precursor and an interleaf sheet out from a cassette, and which, along a conveying path to an exposure section, takes-off only the interleaf sheet. When a leading end of the interleaf sheet passes by an interleaf sheet peeling roller disposed on the conveying path, the interleaf sheet peeling roller rotates in a direction opposite to a direction of conveying to the exposure section, and contacts the interleaf sheet, and slack is formed in the interleaf sheet between the interleaf sheet peeling roller and a conveying roller. A slack portion is nipped between two belts and fed to a forked-off path, and the interleaf sheet is removed from the conveying path. It is possible to feed only the printing plate precursor out to the exposure section while continuing to convey the printing plate precursor.

Image recording material conveying device and automatic image recording system

A device for removing an image recording material is provided, which takes up little space and is used with printing plates and interleaf sheets set alternately in a cassette. An interleaf sheet and a printing plate are taken out simultaneously. In the midst of being conveyed along a conveying path leading to an exposure section, only the interleaf sheet is sucked by a fan or drawn-in between a roller pair so as to be peeled off from the printing plate. The peeled-off interleaf sheet is discarded, and the printing plate is conveyed reliably to the exposure section.

A punch unit ( ) is provided with: a punch ( ), which is reciprocally driven in a punching operation; and, a die ( ), which cooperates with the punch ( ) in punching a hole in a soft metal sheet (i.e., workpiece not shown). In this punch unit ( ): punch guides ( ) and the die ( ) are integrally formed into a punch block ( ); and a radial clearance between the punch ( ) and the die ( ) is set at a value of from 4 to 15% of a thickness of the soft metal sheet to be punched; and, the punch unit ( ) is further provided with a sheet hold-down means ( ) the sheet hold-down means ( ) functioning to hold down the soft metal sheet when the soft metal sheet is punched.

A printing plate is held at one point thereof by a holding portion provided at a surface plate. When pushed by a pushing portion, the printing plate is only rotationally displaced. Thus, an angular error is substantially eliminated and displacement of the printing plate is small. Then, the pushing portion positions the printing plate in a direction perpendicular to a direction in which the surface plate can be moved. Then, movement of the surface plate positions the printing plate in the direction in which the surface plate can be moved.

A punch unit ( ) having a punch ( ) that is reciprocally driven in a punching operation; and, a die ( ) cooperating with the punch ( ) in punching a punch hole in a soft metal sheet. A cleaning means scrapes a soft metal sheet's fragment, when the fragment is stuck to the punch ( ), off of the punch ( ). The cleaning means scrapes the fragment by reciprocally moving the punch ( ) Further provided in the unit ( ) is a punch drive and control circuit ( ). The circuit ( ) enables the punch to be ( ) to perform lost motion at predetermined time intervals. Lost motion enables the punch ( ) to scrape the fragment of the soft metal sheet off a surface of the punch ( ). Consequently, the fragment of the soft metal sheet does not remain stuck to the punch ( ) in the punching operation.
