Disclosed is a disk label printer that includes a slot-in type optical disk driving mechanism and a printing mechanism integrated with each other, has a small size, and smoothly transfers optical disks. The disclosed disk label printer includes: a case that has a slot through which an optical disk is inserted or ejected formed therein; an optical disk driving mechanism that is provided in the case and writes and/or reads signals to and/or from the optical disk mounted to a disk mounting portion; and a printing mechanism that is provided in the case and includes a thermal head which prints a desired image on a label surface of the optical disk. The printing mechanism is provided on a transfer path of the optical disk toward the optical disk driving mechanism between the slot and the optical disk driving mechanism. The thermal head and a platen roller come into pressure contact with each other with the optical disk interposed therebetween on the transfer path, only when the optical disk is transferred during the driving of the printing mechanism. The thermal head and the platen roller are withdrawn from the transfer path so as to be separated from each other, when the optical disk is transferred during operations other than the driving of the printing mechanism.

In a liquid crystal display device, a light quantity control portion b 4,is formed to a dot shape by print or the like on a diffusion plate,interposed between lens sheets,and a light transmission member,on the side thereof near to a backlight source,composed of a cold cathode fluorescent lamp or the like. Since the dots of the light quantity control portion,have a light transmitting property to a certain extent, they reflect a part of the light from the backlight source,and permit the remaining light to pass therethrough. With this arrangement, there can be provided the liquid crystal display device capable of brightly and uniformly irradiating the entire surface of the effective display area of a liquid crystal panel from the backside thereof without emission lines.

Liquid crystal display device with light quantity control portion

A liquid crystal display device contains a liquid crystal panel and a light transmission member disposed below the liquid crystal panel. A reflection sheet is disposed below the light transmission member and a light source is disposed adjacent to one end of the light transmission member. A reflector encases the light source. The periphery of the reflector has reflection walls and forms an opening continuous with the reflection walls. Light direction control walls are formed near the opening of the reflector to control the direction of the light from the light source. The light direction control walls cut off light directed in directions other than a predetermined set of directions. An inner surface of the light direction control walls is composed of reflection layers formed from a different material from the material that forms the reflection walls.
