An acoustic wave device includes: a piezoelectric substrate: a pair of comb-shaped electrodes located on the piezoelectric substrate, each of the comb-shaped electrodes including a plurality of electrode fingers; a support substrate having protruding portions and/or recessed portions in a region overlapping with the pair of comb-shaped electrodes in plan view, the protruding portions and/or recessed portions being regularly arranged; and an insulating layer directly or indirectly bonded between the piezoelectric substrate and the support substrate, a boundary face between the insulating layer and the support substrate being provided along the protruding portions and/or the recessed portions.

Acoustic wave device, filter, and multiplexer

A cartridge handling device for loading and unloading a cartridge accommodating a magnetic tape, magnetic disk or similar recording medium from a processor which is operable with the cartridge. A support plate is reciprocatingly movable in the intended direction of movement of the cartridge toward the processor while extending perpendicularly to that direction. A pair of latch mechanisms are rotatable about individual latch shafts which are studded vertically on the support plate, in order to latch the cartridge when the cartridge is transported. A pair of one-way guide mechanisms are individually associated with the latch mechanisms for controlling the rotation of the latter.
