Abstract: In a reciprocating device, first and second power transmission units are provided on one end side and the other end side of a track to put therebetween power receiving units which are provided on a movable body being movable along the track. Thus, when the movable body is moved close to the one end side or the other end side of the track to separate the power receiving units far from the second power transmission unit on the other end side or the first power transmission unit on the one end side, the power receiving units are able to efficiently receive the electric power from the first power transmission unit on the one end side or the second power transmission unit on the other end side which is close thereto. Therefore, it is possible to reciprocate the movable body between the both ends of the track in a simplified construction.

Abstract: An image transmission method, from an image sensor which collects a fixed number of pixel data items obtained by a plurality of imaging elements into a data block, and outputs the pixel data items, including a transmission region setting step of setting an interest region by using a unit lower than the fixed number, a region extension step of extending the interest region to obtain an extension interest region in which the data block is represented as a unit and obtaining extension ranges from the interest region to the extension interest region, an imaging step of performing imaging with the image sensor, an output step of outputting the data block included in the extension interest region from the image sensor, and an extension range erasing step of erasing pixel data of the extension ranges from the output data block so as to obtain an image of the interest region.

Abstract: An image taking system including: (a) a CMOS or CCD image sensor; (b) an interest-region setter configured to set regions of interest within an image taking area of the image sensor; (c) an acquiring-condition determiner configured to determine an image-data acquiring condition required for acquiring at least two image data generated in at least two of the regions of interest; and (d) an image-data acquirer configured to acquire the at least two image data. The acquiring-condition determiner includes an exposure-time determining portion configured to determine, as the image-data acquiring conditions, at least two different exposure times required for acquiring the at least two image data generated in the at least two regions of interest. The image-data acquirer includes an exposure-time-based-image-data acquiring portion configured to acquire the at least two image data, such that the acquired at least two image data are based on the at least two different exposure times.

Abstract: A component supplying system including a plurality of electronic-component supplying devices arranged to read from an information indicator information, such as ID, that is related to the each supplying device. A guide unit defines the track extending in the direction in which the supplying devices are arranged and that allows the reading unit to be moved along the track. The reading unit detachably attached to the guide unit. The reading unit can perform a reading operation irrespective of the directions the unit is moved along the track. In addition, the reading unit can be moved manually. The guide unit is detachably attached to a component supplying system, and the reading unit includes a wireless transmitter 182 that transmits the read information.

Abstract: It is intended to obtain a reading device that is used in a component supplying system including a plurality of electronic-component supplying devices, such as feeders, that are arranged, and that easily reads, from an information indicator such as a bar code that is affixed to each of the supplying devices, information, such as ID, that is related to the each supplying device. A reading device 100 is constituted by a reading unit 102 including a bar-code reader, and a guide unit 104 that defines a track extending in the direction in which the supplying devices are arranged and that allows the reading unit 102 to be moved along the track. The reading unit 102 has a small size and is detachably attached to the guide unit 104. The reading unit 102 can perform a reading operation irrespective of in which one of opposite directions the unit 102 is moved along the track. In addition, the reading unit 102 can be moved with a hand of a person.
