An inspection system for assemblies, especially for flash units of used film packages as to if the flash units are reusable. The inspection system circulates pallets each holding a flash unit in a predetermined posture around a plurality of inspection stations for various inspection items. Inspection data detected in each inspection station is written in a memory of the pallet through a data communication system disposed in each pallet and each inspection station. A computer reads the memory for classifying the flash unit on the basis of the inspection data on all inspection items and writes classification data in the memory. A plurality of electrical inspection apparatuses are disposed in the inspection system for simultaneously inspecting electrical properties of a plurality of flash units. Each inspection apparatus has proving pins, an actuator and a photo-sensor which are moved into their operative positions when the pallet holding the flash unit is stopped at the inspection apparatus, wherein the inspection apparatus charges a main capacitor with a high D.C. voltage while measuring the voltage of the main capacitor.

Method and system for inspecting an assembly, and electrical inspection

A used lens-fitted photo film unit has a photo film containing section and a front cover. The photo film containing section has a first retaining hook. The front cover has a second retaining hook. The second hook is retained on the first hook, and couples the front cover to the photo film containing section. In a disassembling station, the photo film unit is set in a predetermined orientation. An access plate is advanced toward the photo film unit. The access plate flexes the first hook apart from the second hook, and disengages it from the latter. The access plate is retracted while the front cover is captured by the access plate, thereby to remove the front cover from the photo film containing section. In a preferred embodiment, a flash device from the used photo film unit is supported so as to face upward a flashing face of the flash device. Cleanser liquid is sprayed on the flashing face. Cleaning tape comes in contact with the flashing face. The tape is moved on the flashing face while keeping the tape in contact with the flashing face, and wipes and cleanses the flashing face.

Method and apparatus for disassembling lens-fitted photo film unit, and

A joint inspection apparatus comprises a light irradiating device for irradiating light to a tape joint at which two tape edge portions are joined together, and a light receiving device for receiving the light irradiated by the light irradiating device to the tape joint and passing through the tape joint or reflected by the tape joint. A judgment device is provided for judging the extent of a deviation of the two tape edge portions from each other in the tape width direction at the tape joint on the basis of information on the optical amount of the light received by the light receiving device on both sides of the tape joint.

Joint inspection apparatus

In a method of inspecting a magnetic disk surface, a magnetic disk web is exposed to a light beam, information on the condition of reflection of the light beam by the magnetic disk web or passing of the light beam through the magnetic disk web is detected, and the condition of surface defects of a magnetic disk is judged based on results obtained by the detected information. The judgement is carried out based on the results at a portion of the magnetic disk web outside of a non-use region of the magnetic disk.
