A card reader use in a higher-level device may include a card transfer path; a card insertion detecting mechanism; a transfer roller; a turn detecting mechanism structured to detect a turn of the transfer roller; a card detecting mechanism; and a control unit. The control unit structured such that, if the card detecting mechanism switches from the OFF situation to the ON situation after the card insertion detecting mechanism switches from the OFF situation to the ON situation, even though no turn of the transfer roller is detected by the turn detecting mechanism, the control unit of the card reader sends a control unit of the higher-level device an alarm signal for notifying that a skimming device has been inserted through the insertion slot.

Card reader and card reader control method

A card reader for use with a card having a magnetic stripe may include a card path through which the card having the magnetic stripe is transferred, a magnetic head placed in the card path, and card position detecting sensors for detecting a position of the card. The card position detecting sensors may be located at positions where the magnetic stripe passes through in the card path.

Card reader and processing method thereof

A card reader may include a first card operation part having a first reproducing and recording part, a first feeding passage, and a first card pressing mechanism structured to press the card toward a first card feeding reference face, and a second card operation part having a second reproducing and recording part, a second feeding passage, and a second card pressing mechanism structured to press the card toward a second card feeding reference face which is formed on the opposite side to the first card feeding reference face. The first and second card operation parts may be adjacently disposed in a feeding direction of the card. The first and second reproducing and recording parts may be disposed in a substantially point-symmetrical manner.

Card reader with first operation part and second operation part

A USB communication system, a USB device, and a method of error detection for the USB communication system; with which an error of any breaking of physical connection in USB communication can be detected no matter where the breaking happens, and furthermore an error due to logical communication disconnection can also be detected. In a USB communication system constructed by connecting a host apparatusand a card readerwith a USB cable, the card readermay include: means for executing a bus reset as a preprocessing for setting a logical connection line with the host apparatus, means for measuring a time while the card readeris in a bus reset status, and means for executing an operation of interrupting communication voluntarily according to a measuring result of the means for measuring the time.

USB communication system, USB device, and method of error detection for USB communication system

In a nonvolatile memory such as flash memory where data is stored sector by sector, a method of overwriting a data sector is provided. The old data to be overwritten in a data sector along with its error detection code are initially saved to a backup region which is also in a non-volatile area. The old data in the data sector is then erased and new data along with its own error detection code are written into the same data sector where the old data was previously stored. When a power outage occurs during the overwrite process, error checking is performed to determine whether the data in the data sector is valid using the associated error detection code. Because the old data is saved in a non-volatile area, even if such unexpected power outage occurs during the overwrite process and the data in the data sector is determined to be invalid, at least the old data can be recovered from the non-volatile backup region which is not affected by the power outage.

Method of overwriting data in nonvolatile memory and a control apparatus used for the method

An automatic bread maker capable of permitting a user to easily perform a necessary work in using the bread maker, such as setting of menu and preparation of materials, without referring to an operation manual or a cooking recipe. This automatic bread maker comprises: a bread baking mold having a kneading blade at an inner bottom portion thereof; a baking case for detachably accommodating said bread baking mold and having a heater mounted along an inner wall surface thereof; a temperature detector for detecting temperature in the baking case; a memory for storing a plurality of bread making menus and data regarding each menu; a display device for displaying various data stored in the memory; an input operation panel for inputting a start command of a bread making operation and selection of the bread making menu; and controller for invoking various data from the memory in accordance with the bread making menu inputted through the input means. The display device comprises a liquid-crystal display having a surface to which a touch switch is affixed and functions as the input operation panel.
