Abstract: A new connector that is reduced in size and has a higher density of contacts implemented therein is provided. This connector has a contact module arranged on a connector main body. The contact module is formed into a sheet structure, and a plurality of contacts are arranged therein. Further, the contact module is bent into a C-shaped structure along the extending direction of the contacts, and is implemented to the connector main body in this state. Contact points of the connector are energized by sets of a coil spring and two push pins arranged on both sides of the coil spring so that these contact points protrude from holes formed at the connector main body.

Abstract: A signal obtained by optically scanning a bar code is subjected to differentiation to obtain differential data. Peak-to-peak distances are calculated from the differential data. When a peak-to-peak ?Tx distance is y times of a basic width, frequency f(x,y) will be, f(x,y)=y/?Tx. A frequency map is prepared from the frequencies calculated. Transition routes in which one frequency each is selected. from each of the peak-to-peak distances, are formed. A transition route for which an error in frequencies is the least is taken as the most suitable transition route. An average of the frequencies included in the transition route is taken as a frequency f0 of the basic width.

Abstract: An extractor extracts a part that is apparently a bar-code signal from a signal that is subjected to opto-electric conversion. A narrow-band differential processor forms a waveform of an edge by differentiating by using a module frequency. The module point extractor extracts the module point from the waveform. The maximum likelihood judgment processor 5f performs ternarizing based on a maximum likelihood method by using broader information.

Abstract: A signal fetching unit fetches a signal that includes binarized information disposed with a predetermined information length, from a barcode. A module-frequency extracting unit extracts a module frequency equivalent to a basic unit length in the binarized information from the signal. A frequency shifting unit shifts a frequency to 0 Hz based on the module frequency for the signal. A low pass filter passes a low frequency component included in an output signal from the frequency shifting unit. A module-point extracting unit extracts a module point synchronized with the signal and that has the module frequency, based on the module frequency extracted and an output signal of the low pass filter. A demodulating unit demodulates a character of the barcode based on the module point extracted.
