A multilayer type optical information recording medium in which in multilayering of a write-once type optical information recording medium, when a second film is formed using a metallic stamper, a protective layer composed of an inorganic material is free from peeling, is provided. In the multilayer type optical information recording medium including an interlayer, the interlayer is constituted by multiple films of a first film contacting a protective layer and a second film contacting a reflection layer; materials of the first and second films are constituted of materials different from each other; and a peeling resistance of the material of the first film against a material of the protective layer of the first optical information recording layer is higher than that of the second film.

Optical information recording medium and manufacturing method therefor

In an electronic component placing apparatus, four magazines are mounted on a head, and yet electronic components are housed in each magazine. In this apparatus, by an operation of selectively inserting a suction nozzle into four insertion openings in the magazines, it is possible to load a desired electronic component on a substrate, and this component loading can be repeatedly performed until the housed components are exhausted.

Electronic component placing apparatus

A component supply apparatus includes a rectangular cross-sectional component passage which can house a plurality of chip components in a longitudinal direction, and at a first side surface of the tip of this component passage a rectangular-shaped component discharge opening is formed, and at a second side surface opposing the first side surface of the tip of the component passage a rectangular-shaped pusher insertion opening is formed. Inserting the pusher into the component passage through the pusher insertion opening enables a forefront electronic component to be pushed by the pusher and be discharged outside from the component discharge opening in a predetermined direction.
