An operating switch for commanding actuation of an electric parking brake mechanism includes two input terminals and two output terminals, a pair of two wirings for each input-terminal/output-terminal pair of the two input terminals and the two output terminals, each of the wirings being located between the input terminals and the two output terminals, a first switch element provided for the input terminals or the output terminals, and configured to switch connections to the two wirings, according to a command for the actuation, and a second switch element connected to one wiring of the two wirings that connects the input terminals and the output terminals when the command for the actuation given to the first switch element is set to a mode of non-operation. The second switch element is configured to switch connections to the two output terminals or the two input terminals, according to the command for the actuation.

In a speaker damper, art sections are disposed on warp reference lines and warp reference lines. Straight sections are disposed so as to intersect intermediate reference lines at right angles. By adopting this configuration, wave parts can be adjusted so that they are less likely to expand/contract on the warp reference lines and the warp reference lines in comparison with related-art concentric circular wave parts. Further, the wave parts can be adjusted so that they are more likely to expand/contract on the intermediate reference lines. In this way, the speaker damper can perform uniform vibrating motions throughout the entire speaker damper with a simple configuration.

Speaker damper and speaker unit

The apparatus has an optical unit for optically reading the article barcode provided to the article. The controller sets operation standard as the reference for occurrence of barcode reading errors, on the basis of individual operator setting information depending on personal features (rhythm, habitual manner, etc.) of operators engaged in operation of reading barcodes. The controller also monitors whether the operation relating to the operator conforms to the operation standard or not.

Method of and apparatus for reading

A still image of a moving object is restored from portions including the object in an image by using a movement distance of the object during an exposure time and the difference value between output values of adjacent pixels, the movement distance being calculated as a number of pixels. Therefore, especially in cases where a moving bar code is imaged, even if the image of the bar code is blurred as a result of the movement of the bar code during imaging, a still image of the bar code in which the outlines of the black portions and white portions of the bar code are clear can be obtained. Accordingly, bar code information can be read out from the imaged bar code.

Imaging device

A commodity information management system including a deactivator for deactivating a security tag activated and attached to a commodity after a barcode is read by a reader, a magnetic detector for detecting magnetism of the security tag having been deactivated by the deactivator, and a control section for sending the result of detection by the magnetic detector to an operator with an LED and a speaker. The operator recognizes whether the security of the security tag is released or not according to the light through the LED and sound by the speaker.

Commodity information management system

A bar code data detecting section of a bar code reader scans a bar code twice or more and detects multiple pieces of bar code data, and a decoder decodes the bar code data, Then, a first judging section detects the overlapping part where first decoded data of the decoded in a first scanning trace and second decoded data in a second scanning trace overlap and judges whether or not the overlapping part is composed of a predetermined number of characters. If the overlapping part is composed of the predetermined number of characters, a second judging section judges whether or not the data in the overlapping part of the first decoded data is identical with that of the second decoded data. If the characters are the same, a fourth judging section judges whether or not the character just before the overlapping part of the first decoded data, the character just after the overlapping part of the second decoded data, and the characters constituting the overlapping part are all the same. If they are all the same, a synthesizing section does not combine the first and second decoded data from being generated.

Bar code reader and bar code reading method

A method of the invention reads a bar code based on bar-code data obtained by scanning the bar code with light. The method includes the steps of a) obtaining bar-code data, b) obtaining a sum of bar-data widths with respect to a predetermined number of bar data provided in at least one of a preceding portion and a following portion of the bar-code data, c) repeating the steps a) and b) once to obtain another sum, and d) making a comparison of the sum with another sum. The methods further includes a step of accepting the bar-code data as valid data when a result of the comparison satisfies a predetermined condition.

System and method of reading bar code with two scanning beams

A POS system comprises a host computer providing a centralized control over a plurality of scanners, and a printer for printing a batch setting bar code or the like. A CPU of the scanner reads the changes in the setting from its own memory when it receives a first transmission request command and then transmits the data to the host computer as a first batch setting data. From this first batch setting data, a first batch setting bar code is generated. When this first batch setting bar code is read using the reader of the scanner whose setting has not been changed, the setting in the memory of this scanner is changed to the setting represented by the first batch setting data. Thus, setting in a plurality of scanners can speedily and accurately be changed.

A bar code reader includes bar code processing units ( ) for generating a bright/dark pattern forming a bar code ( ) by optically scanning a bar code forming surface of an object ( ), converting into plural categories of module values indicating widths of the respective areas, and demodulating the bar code into character data, a scaling unit for creating scale data by scaling a weight of the object to be sold by weight, a adjustment control unit ( ) to perform zero-setting in response to a request for initializing the scaling unit, and a weight change detecting unit ( ) for judging at least one of an increment change and a decrement change from zero in weight, and making a corresponding piece of scale data visibly displayed when in the increment change and making an absolute value of a corresponding piece of scale data visibly displayed when in the decrement change.

Bar code reader, scaling device and scaling method

A differentiation signal DF differentiated by a differentiation unit is inputted to a slice level generation unit and to comparators. A first peak-hold circuit and a voltage division circuit generate a slice level having a slice ratio SLR that is constant to a peak value V of the differentiation signal DF. A second peak-hold circuit generates a slice level the slice ratio SLR of which changes in accordance with the peak value V . The slice level generation unit outputs their synthetic slice level SLL, which is compared by the comparators with the level of the differentiation signal DF, outputting thereby binarized signals W-GATE and B-GATE. When the level of the differentiation signal DF is high, the slice level SLL approaches the peak value V . Therefore, noise components contained in the differentiation signal DF cannot exceed the slice level SLL. When the level of the differentiation signal DF is low, the slice level SLL has a constant ratio to the peak value V . Consequently, the peak value of the amplitude of the differentiation signal DF can be detected reliably.

A ratio between a character length C of an already decoded character E and a length C of a character E to be decoded is calculated. When this ratio is greater than a threshold value, the black bar width B and black bar width B are corrected according to a reference black bar width X. The CPU decodes the character E to be decoded according to the corrected black bar width B and black bar width B .
