摘要： PROBLEM TO BE SOLVED: To provide a scan module which is used for the purpose of requiring a compact reader. SOLUTION: A non-retroreflective compact scan module in an electro-optical reader includes a laser light source, a photosensor, and an electromagnetic coil which are mounted at one surface of a printed circuit board. The laser emits a laser beam perpendicular to the board and is redirected to an oscillatable sac mirror, which is magnetically centered to a rest position, when the coil is de-energized.

摘要： PROBLEM TO BE SOLVED: To provide a scanning module used for applications requiring a compact reader. SOLUTION: The non-retroreflective compact scanning module of an electro- optic reader includes a laser beam source attached to one surface of a printed circuit board, a photosensor and a electromagnetic coil. The laser emits the laser beam perpendicularly to the circuit board and when the coil is degaussed, the laser beam is directed again to the oscillatable scanning mirror which magnetically comes to a central position of rest.

摘要： PROBLEM TO BE SOLVED: To obtain a small-sized electro-optic retroreflection scanning mode equipped with all necessary components and a completely built-in type. SOLUTION: This retroreflection scanning module is equipped with a base part, a 1st circuit board 416, and a 2nd circuit board 418 which is fitted almost at right angles to the 1st circuit board 416. The base part supports a light radiation body, which generates a scanning beam and an optical component which directs and converges light energy. A radiated beam reflection body reflects the light from a return mirror 212 on a reflection body fitted to a drive part for an oscillation body. The reflection body changes the direction of the beam to a mark to be read. The mark is scanned with the beam through the vibration of the reflection body. The reflected light is directed to the vibrating reflection body and made incident on a converging mirror 204, before reaching a detector 206. The detector 206 included in the module detects the light reflected from the mark scanned with the beam. The beam and the visual field of the detector 206 are scanned at the same time. Various implementation styles of vibration drive and optical arrangement are disclosed to make the scanning module small-sized.

摘要： PROBLEM TO BE SOLVED: To enable executing a network provided with plural data transfer rates by evaluating the performance of mobile units, scanning the most appropriate access point by means of a set interval, when the performance is lower than a threshold and relating it with the most adequate access point by means of the highest data rate. SOLUTION: When each precise packet response(PPR) is received, the quality of a response signal is evaluated and updated, by measuring a reception signal strength display(RSSI). Appropriate group of the access points lower than the best detection RSSI value is selected, and each mobile unit executes full-scanning and inspects all channels with precision. A prefetching shift for adjusting a dynamic load is enabled in a system, and re-relating with the new access point is enabled. Thus, a possibility in which the mobile unit being unable to communicate with any one of the access points and experiences a period without communication is avoided.

摘要： PROBLEM TO BE SOLVED: To provide an interface between a radio LAN and a gateway by detecting a message to be transmitted by a first mobile unit, discriminating, determining whether a route for other mobile unit is determined in the message or it is transferred to other channel and a route for other type of communication station is determined in the message and connecting the gateway with an access point. SOLUTION: A function to transmit and receive a data frame by a proper format, to transmit the data frame from a transmitter/receive 52 at proper time or to make the transmitter/receiver 52 receive the data frame is executed by a medium access control MAC processor 54. The processor 54 is connected with a memory 58 to buffer a data packet. The memory 58 is connected with a switch to perform a processing and switching to determine the route of the data packet, namely, a processor and a multiplexer/demultiplexer 60. A signal received from a cable is received by a cable modem receiver 90 to transfer information to the multiplexer/demultiplexer 92.

摘要： PROBLEM TO BE SOLVED: To provide a transceiver including a transmitter block and a receiver block. SOLUTION: A transmitter block includes a modulator 22 used to modulates data information on a carrier signal. A receiver block adopts a heterodyne system to convert the carrier into an intermediate frequency signal. The modulator 22 and the converter are formed on a single semiconductor chip. The receiver block receives a signal in a plurality of channels for a prescribed band width and a sampler samples the signal by a frequency lower than twice of the prescribed band width. The sampling frequency is selected so that the frequency of the selected channel is converted into a prescribed intermediate frequency and the frequency of the other channels is converted into a frequency higher than the intermediate frequency. The converted signal is converted into a digital signal. A demodulator 56 includes a Hilbert transformation versus filter block. A 1st AGC circuit adjusts the gain of an AGC circuit and a 2nd AGC circuit adjusts the amplitude of a digital signal.

摘要： PURPOSE: To provide a simple and inexpensive means for adjusting the profile (width at a specified distance from a light source) of a beam in the direction of 'y' as in a desired way. CONSTITUTION: The optical scanner such as a bar code scanner contains a laser diode and generates a scanning laser beam. The laser diode has astigmatism on a characteristic. When the beam 18 passes through a lens having rotational symmetry, the beam 18 is contracted in the direction of 'x' (scanning direction) and the direction of 'y' (right angled direction). The width of the outline of the beam in the direction of 'x' is adjusted by a conventional lens. The width of the outline of the beam in the direction of 'y' is adjusted by using a non-planar mirror, a cylindrical mirror 200 if desired, as a rotary or rocking element.

摘要： PURPOSE: To provide a scanning module which can be improved in sighting and emitting abilities, scanning pattern visibility, and shock resistance, can be constituted in a compact state, and reduced in the cost. CONSTITUTION: The optical scanning of a bar code symbol is first performed in a sighting mode for scanning the symbol by using a closer first scanning pattern so that the symbol can be seen by a user in a relatively small size, and then, a larger and stronger second scanning pattern for decoding. A preferable scanner module is provided with a scanning mirror fitted to a bracket through a leaf spring and the leaf spring is constituted so that the mirror can be vibrated in one direction. The spring is hung from a fixed chassis by using two strips of a mylar (R) film. The two strips themselves are protected from mechanical shocks by means of pins passed through the holes of the bracket. The pins make the bracket to be accurately aligned with the chassis.
