摘要： A backlight system (30) includes a light emitting section (31) and an imaging optical system. The imaging optical system includes a first microlens array (MLA1) and a second microlens array (MLA2). The lenses (1A) separates the beams of light emitted from the light emitting section (31) by RGB, and causes them to be converged at a pitch same as a pitch at which the picture elements are arrayed. The lenses (2A) are provided in one-to-one correspondence to the picture elements such that the lenses (2A) have their respective focal points at positions onto which beams of light having passed through the lenses (1A) are converged. The lenses (2A) thus deflect the beams of light which have passed through the lenses (1A) in a substantially vertical direction with respect to the display surface of the liquid crystal panel.

摘要： The three-side trimmer comprises an alignment station (F) for receiving booklet bundle (32) and aligning the booklets, and a cutting station (D) for cutting the top, bottom and fore edges of the bundle, and a chuck mechanism (40) which holds the bundle and conveys it to the cutting station. The cutting station has a cutting table (23), a top edge cutting knife (43), a bottom edge cutting knife (44), a fore edge cutting knife 42, and a pressing plate 48 movable between a waiting position and a working position. An encoder reads the data about the rotational position of the servomotor (38) in the chuck mechanism while it holds the booklet bundle. The control portion (25) measures the height of the bundle and controls a driving mechanism of the pressing plate such that the pressing plate moves up and down between waiting and working positions.
