Description

  The present invention relates to a receiving tray for reflecting mirror bases that accommodates a large number of reflecting mirror bases in parallel, a stack using the receiving tray, and a package thereof.

  As the light source lamp of an illuminating device, a projector or the like becomes higher in brightness, the heat generation becomes more remarkable, and the temperature rise of the reflector used in combination with the light source lamp also becomes severe. In particular, in recent years, the brightness of light source lamps and the miniaturization thereof have progressed in various fields, and the reflecting mirror portion has a high temperature exceeding 550 ° C. In general, a reflecting mirror is composed of a substantially bowl-shaped reflecting mirror base having a concave curved surface opened forward, and a reflecting film coated on the concave curved surface of the reflecting mirror base, both of which have heat resistance characteristics that can withstand high temperatures. It becomes. Therefore, at present, the reflector substrate is made of borosilicate glass or crystallized glass having a low thermal expansion coefficient.

  Conventionally, the reflector substrate is transported and transported in a state in which a plurality of reflector substrates are accommodated in a corrugated cardboard case in which a housing space is partitioned by a grid-like partition, and the corrugated cardboard cases are stacked. However, the transportation by the corrugated cardboard case has a problem in that the reflecting mirror base has a substantially bowl-like shape, and therefore there is a lot of wasted space in the accommodation space, which increases the transportation cost and storage cost of the reflecting mirror base.

  To date, a packaging pad for transporting a funnel for CRT display with less wasted space has been proposed (see, for example, Patent Document 1 below). However, since this packing pad is stacked with the pad frame portions in contact with each other, the pad itself needs to have a predetermined strength, and there is a limit to reducing the transportation cost by making the pad itself thinner and lighter. there were.
