Abstract: PURPOSE:To improve accuracy by providing a lens holding member, a magnetic yoke member supporting the holding member and a base member on which the magnetic yoke member is attached position-adjustably accompanying the lens holding member. CONSTITUTION:A pair of focus control coils 54 are moved to the X axis direction by the magnetic field of a magnet 30 and applied with electromagnetic force in accordance with the polarity and the level of a focus control signal. Therefore, a bobbin member 48 sticking a coil 54 is moved to the X axis direction in accordance with the arm member 42 of a movable member 38 and thus, an objective lens 6 fixed on the bobbin member 48 is moved to the axis direction according to the focus control signal. Further, the bobbin member 48 sticking a tracking control coil 55 through a coil 54 is rotated and moved by regarding the hinge part 46a of the movable member 38 as a fulcrum and thus, the lens 6 fixed on the member 48 is moved in the direction vertical to the light axis direction according to a tracking control signal. Thus, a manufacturing cost is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner device which can be made small in size and low in profile and can be operated highly precisely. SOLUTION: The optical scanner device is provided with: a floodlight part 10 which projects light toward a bar code BC; and a light receiving part 20 which receives reflected light from the bar code BC. The floodlight part 10 uses a ball lens 40 as an optical element which condenses light emitted from a light source 30 composed of a laser diode. The ball lens 40 precisely guides the light from the light source 30 to a reflection member 50 because the ball lens 40 is more easily positioned in an optical axial direction than a convex lens. Further, the light source 30 is arranged with respect to the reflection member 50 so that a scanning is performed with laser light in a direction where the beam diameter is small.

Abstract: PROBLEM TO BE SOLVED: To obtain a marking unit which can print a high quality character through simple structure wherein an optical head is inclined by a predetermined angle in the scanning direction when an object is printed by irradiating with a plurality of luminous flux emitted from a plurality of light emitting sections. SOLUTION: The marking unit 1 prints an easily distinguishable high quality character by emitting laser light from an optical head 5 arranged with a plurality of fibers 4 while inclining 30 deg. or 45 deg. with respect to the scanning direction thereby limiting the interval between dots constituting a character without decreasing the diameter of each fiber 4a-4g. According to the method, the scanning distance is shortened at the time of printing a character or the like as compared with a case a character is printed by converging the laser light at a point. Furthermore, pulse control is performed while shifting the irradiation timing of each laser light by an amount corresponding to the inclination of optical head 5.

Abstract: PURPOSE: To reduce a base supporting a magnetic yoke, a lens holding member, etc., by mounting the magnetic yoke member on the base member separately formed therefrom so as capable of adjusting the position in company with the lens holding member. CONSTITUTION: A tracking control signal is supplied from a supply part of tracking control signal to a group of a pair of tracking control coils out of two groups through a printed circuit provided on a flexible connecting substrate 58. A bobbin member 48 is thereby moved along a magnet 30. In this case, the bobbin member 48 is turnably moved by making a hinge part 46a of a movable member 38 as the fulcrum, and one out of a pair of tracking control coils is come close to the magnet 30 and another one is separated out from the magnet 30. As the result, an objective lens 6 is moved in the direction along a guide shaft 16 which is extended along the radial direction of a disk D, in accordance with the tracking control signal.
