Abstract: PURPOSE: To increase the focal depth as much as possible and to reduce the beam size in the focus position as much as possible by providing an optical means with a converging means and an aperture diaphragm which is arranged between a laser light source and a symbol part and closely to the converging means in the optical path. CONSTITUTION: An aperture diaphragm 56 which directly determines the beam size is arranged in the optical path of emission of laser light. The cross section of the aperture diaphragm is smaller than that of laser light in the position of the aperture diaphragm and is so constituted that a part of laser light from a laser light source 42 passes through but the other part is intercepted, and the optical system includes a converging lens 62 consisting of a piano-convex lens and the aperture diaphragm 56 which is arranged in the optical path closely to the converging lens 62. A part of the emitted laser diode beam is allowed to reach a symbol through this aperture diaphragm 56. Thus, convergence to a desired beam size is realized for a sufficient operation time by the simple constitution of the single lens.

Abstract: PURPOSE: To improve the reliability of a laser scanner for reading a bar code symbol by increasing the small amplitude of high frequency component of an analog signal while using a reinforcing means in order to reinforce the modulation of the analog signal. CONSTITUTION: This device is provided with light guiding means 33 and 34 for guiding light to a display in order to reflect the light, a means 19b for scanning the display along a scanning direction with sampling aperture larger than the width of one narrow element at least having a dimension along the scanning direction, a detecting means 17 for generating a modulation degraded analog electric signal having the high frequency component of small amplitude corresponding to a narrow element and the low frequency component of large amplitude corresponding to a wide element by detecting the beams having various values of strength reflected from the display along the scanning direction, and the reinforcing means for converting that signal to a modulation reinforced analog electric signal having the low frequency component and high frequency component mutually making much closer the values of large and small amplitudes by amplifying the modulation degraded electric signal. Thus, the modulation degraded analog signal can be read well and the reliability of the scanner can be improved.

Abstract: PURPOSE: To use a relatively small-sized laser light source to operate the device with a low voltage by providing a semiconductor laser diode which is supported on a laser scanning head and generates laser light and holding the scanning head in a position distant from a bar code to read the bar code. CONSTITUTION: A small-sized light source means for generation of laser light consists of a semiconductor laser diode 200 and is attached to a body part 14 with a supporting plate 30 between them by rubber bands 36 and 38. DC power of 12V for the laser diode 200 is led into the inner chamber of a handle part 12 through a cable 58. This 12V DC power supplies proper anode voltage and anode current to the anode of the laser diode 200. The cathode of the laser diode 200 is earthed. Thus, the device itself is small-sized and light-weight, and the laser diode is operated with a low-voltage power source, and therefore, the power source part is made light-weight and small-sized, and not only insulation is facilitated but also the device is made small-sized and light-weight furthermore.

Abstract: PURPOSE: To eliminate the restriction of a using place by providing a decoding means decoding an electric signal from a detection means and a power source means within a portable pack different from a scanning hand and connecting the scanning head and the pack through a flexible electrically connecting means. CONSTITUTION: A portable laser scanning head 10 includes a gun-shaped housing with a handle part 12 and a waist part 14. The portable head 10 is connected with the other elements through a flexible and not-bulky cable 58. As the other elements a computer circuit for decoding a digital signal, a data storing circuit, etc., are included and a power source 50 and a controlling power source for a control circuit are included to be incorporated in an appointment which a user wears. An analog electric signal is formed from a reflected beam from a bar code and this analog electric signal is converted to a digital electric signal to be sent to the outside of the scanning head in the form of a digital signal. Thereby the user does not receive the restriction of the using place.

Abstract: PURPOSE: To provide a comparatively inexpensive and lightweight convergent module for a divergent light source by providing the module with a 1st aperture for restricting a circular part for receiving a laser diode assembly and a 2nd aperture end for restricting a 2nd circular part having diameter smaller than that of the 1st circular part. CONSTITUTION: A diode holder 30 has the 1st circular part 35 and the 2nd circular part 31 having shorter diameter than the 1st circular part 35. A lens holder 40 is held in the holder 30. The 1st circular part 35 holds the flange 41 of the holder 40. The flange 41 has a diameter larger than that of the 2nd circular part 31 and the holder 40 is prevented from being rotated around the center axis of the holder 30 due to the existence of a notch 49 in the flange 41 of the holder 40 which is cooperated with a groove 32 formed in the 1st circular part 35. Consequently an highly accurate focusing or convergent module having inexpensive structure can be obtained.

Abstract: PURPOSE: To make it possible to read a symbol without using an optical targeting mechanism by visually observing a laser beam with increased visibility, and by positioning this laser beam on a symbol desired to be read over a range of operating distance wider than the head. CONSTITUTION: In order to increase the visibility of a laser beam radiated by a diode 33, the magnitude of a focusing lens 32 is increased to an extent around ×45-×50, an aperture diaphragm 45 is enlarged, and the laser scanner is operated without compensating astigmatic characteristics in such a state that the diode 33 has such astigmatic characteristics. The operator visually observes a laser beam with increased visibility, and positions this laser beam on a symbol desired to be read over a work distance range long extended to housings 12a and 12b. With that, the laser scanner can read a symbol without using any optical targeting mechanism.
