    • Aspects of the invention provide a projector capable of comparatively easily achieving a contrast ratio higher than the original contrast ratio of the liquid-crystal light valve by a simple mechanism. The illumination light modulated by liquid-crystal light valves, i.e., image light, can be combined together in a cross dichroic prism, and then light intensity of suitable pixels is reduced by a proper amount by a liquid-crystal light valve, and then sent to a projection lens. The image light entering the projection lens can be projected to a projection surface. Because the light intensity of the image light formed by the liquid-crystal light valves is appropriately attenuated at suitable pixel areas by the liquid-crystal light valve, image light projection with a contrast ratio exceeding by far the contrast ratio achievable by the liquid-crystal light valves alone is possible due to cumulative light-intensity adjustment.
    • 本发明的一个方面提供一种能够通过简单的机构相对容易地实现比液晶光阀的原始对比度高的对比度的投影仪。 由液晶光阀调制的照明光,即图像光可以在十字分色棱镜中组合在一起,然后通过液晶光阀将适当像素的光强度降低适当的量,然后发送 投影透镜。 进入投影透镜的图像光可以投影到投影面。 由于由液晶光阀形成的图像光的光强度在适当的像素区域被液晶光阀适当地衰减,所以对比度超过液晶可实现的对比度的图像光投射 由于累积的光强度调节,单独的光阀是可能的。

    • A connector includes contacts each having a contact portion, an elastic portion and a fulcrum portion between the contact portion and a connection portion, and a pressure receiving portion; a housing fixing the contacts; and a slider having urging portions pivotally moved between the connection and pressure receiving portions of the contacts to urging the contact portions against the circuit board, thereby achieving reliable connection and miniaturization of the connector. In an aspect, the housing is formed on the side of a board insertion opening with a recessed portion for conducting the board. In another aspect, the contact includes upper and lower contact portions one above the other arranged alternately staggered so as to be connected to a circuit board having contact portions alternately staggered, so that no defective connection occurs, even if the circuit board is inserted erroneously upside down. In a further aspect, the connector further includes locking members having an engaging portion which engages an anchoring portion of the circuit board to prevent the circuit board from being removed. In one aspect, contacts of two kinds are inserted into the housing from opposite sides, respectively so that these contacts of the two kinds are into contact with the contact portions on respective surfaces of the circuit board. In a further aspect, moreover, a plate-shaped piece is provided in opposition to the contact portions of the contacts to prevent the housing from being deformed.
