    摘要: A light source module has a laser diode, and a circuit board. The circuit board includes the laser diode, a driver circuit for the laser diode, and a connector for receiving a power supply for driving the laser diode from an electric power source. A lens and an aperture shapes the laser beam emitted from the laser diode. A housing made of electrical insulating material contains the lens, the aperture and the circuit board except for a portion of the circuit board where the connector is mounted.

    摘要: A bar code reader having two reading windows, i.e., a bottom window and a side window. An increased number of scanning lines are used for constituting scanning patterns for scanning bar codes, and the arrangement of the optical system is contrived to decrease the whole size of the bar code reader and, particularly, to decrease the depth of the bar code reader. A source of laser light, a splitter for splitting the laser beam emitted from the laser light source into two, a reflection mirror for transmitting one beam from the splitter to a polygon mirror, the polygon mirror which rotates to scan the incident laser beam, a mirror system for emitting the beam reflected by the polygon mirror through the reading window, and a focusing member for focusing the beam reflected by the bar code onto a detector that detects the beam reflected by the bar code, are arranged on the same line in the bar code reader. By using a concave mirror, furthermore, the beam reflected by the bar code is folded back to one detector. The light-receiving surface of another detector is faced downward to receive the beam reflected by the bar code through Fresnel lens and mirror, thereby to decrease the depth of the bar code reader. Furthermore, the beam passage from the reflection mirror goes through the lower surface of the polygon mirror intersecting the axis of rotation of the polygon mirror.

    摘要: A multi-head optical scanning device used for a bar code reader having a reduced thickness and realizing more complete 360° bar code reading. The scanning device includes a bottom part, a side part which is nearly vertical to the bottom part, a light source, a polygon mirror and a light detector contained inside the body of the side part. Light beams are emitted from the light source so that they are nearly vertical to the surface of the bottom part, and the polygon mirror has a rotation axis at a position which is nearly parallel to the surface of the bottom part. The optical scanning device eliminates the need for a mechanism which performs scanning inside the bottom part and the degree of freedom with which each of the pattern mirrors is disposed is increased, and provides a scanning pattern whose reading capacity can be upgraded by using a scanning pattern which is emitted from the bottom part.
