A manufacturing apparatus (20) has first and second reel-out mechanisms (32a, 32b), first and second processing mechanisms (36a, 36b), first and second label bonding mechanisms (40a, 40b), first and second reservoir mechanisms (42a, 42b), first and second peeling mechanisms (44a, 44b), a substrate feed mechanism (45), an attachment mechanism (46), and a base peeling mechanism (186). A cooling mechanism (122) is disposed between the attachment mechanism (46) and the base peeling mechanism (186), for cooling an attached substrate (24a), the attached substrate (24a) being made up of a glass substrate (24) and a photosensitive web (22) attached thereto, from which a protective film (30) has been peeled off, together with a heating mechanism (182) for heating a resin layer, for example a cushion layer (27), inside the cooled attached substrate (24a) to within a predetermined temperature range, which is at or below the glass transition temperature.

A manufacturing apparatus (20) has a reel-out mechanism (32), a processing mechanism (36), a label bonding mechanism (40), a reservoir mechanism (42), a peeling mechanism (44), a substrate feed mechanism (45), and a joining mechanism (46). A detecting mechanism (47) for directly detecting a boundary position of a photosensitive web (22) is disposed upstream of and closely to the joining mechanism (46). Based on detected information from the detecting mechanism (47), a relative position of the boundary position and a substrate (24) in a joining position is adjusted.

A film cartridge assembling apparatus including one or more assembly chucks each including two die elements formed by combining partial cylindrical inner surfaces thereof together. The circumference of a resulting cylinder being partially cut to form an opening. One of the die elements includes a member having a flat surface extending from an end of the cylindrically-shaped inner surface towards the opening. The member is adjustably mounted to the one of the die elements The assembly chuck is able to assume a closed state in which the two inner surfaces of the two die elements are matched to each other to form a cylindrical inner surface and an opened state in which ends of the two die elements substantially parallel to the center axis of the cylindrical inner surface are spaced apart form each other.

摘要:
A method and an apparatus for manufacturing a film cartridge operable at high speed.A film cartridge comprised of a rounded ribbon plate and a cap clinched to the end of the rounded ribbon plate is produced using an apparatus including plural assembly chucks, an index unit for holding the assembly chucks at equi-angular intervals about a rotation axis and a driving unit for intermittently rotating the index unit. The method includes a step of introducing a rounded ribbon plate into an assembly chuck, a step of introducing a cap to a side end of the cylindrically rounded ribbon plate, in conjunction with the ribbon plate introducing step, when the assembly chuck holding the rounded ribbon plate is halted at a different halt position, and a step of clinching the cap to the ribbon plate, in conjunction with the ribbon plate introducing step, when the assembly chuck holding the ribbon plate having the cap inserted therein is halted at a further different halt position.

An electrophotographic developer is provided that attains improvement in reliability by improvement in cleaning property and reduction in wear of a photoreceptor in a well-balanced manner without impairing high transfer efficiency and high image quality of a spherical toner. The electrophotographic developer contains a toner and a carrier, the toner containing spherical colored particles having an average shape factor (ML2/A) of about from 100 to 135 and irregular-shaped non-colored particles having a volume average particle diameter of about from 1 to 10 &mgr;m, a charge distribution of the developer having a peak value Q/Ma ascribable to the spherical colored particles and a peak value Q/Mb ascribable to the irregular-shaped non-colored particles, and the peak value Q/Ma and the peak value Q/Mb satisfying both the following formulae (1) and (2): 20 &mgr;C/g≦|Q/Ma|≦85 &mgr;C/g (1) −0.7 Q/Ma≦Q/Mb≦0.5 Q/Ma (2).

When any of facilities of a film producing and packaging system suffers a failure, a film processing controller shuts off the film producing and packaging system. The operator repairs a failing facility and manually discharges a length of an elongate film which may possibly be defective. After the failing facility is repaired, the film processing controller is restarted to operate the film producing and packaging system, which then automatically discharges a length of the elongate film corresponding to a preset number of sized films. It is possible to easily and quickly discard a portion of the elongate film which has been made defective by the facility failure.
摘要:
A process for producing packaged products from a film roll includes the steps of detecting whether an elongate film is defective or not, detecting whether a spool is defective or not, detecting whether an assembled cartridge is defective or not, and detecting whether a case is defective or not. Various defective products detected in these steps are removed without being fed to subsequent steps. By thus detecting various defects in the process for producing packaged products from a film roll, high-quality packaged products can efficiently be manufactured.

A carriage has a support shaft for supporting a plurality of film rolls and can be closed by a light shield cover to place the film rolls in a light-shielded state. A film roll storage mechanism is disposed in a dark room and has a shank for receiving the film rolls from the carriage. The film roll storage mechanism can transfer the film rolls one at a time from the shank onto a film unwinding shaft. A positioning mechanism positions the support shaft and the shank coaxially with each other and locks the carriage with respect to the film roll storage mechanism.
