Abstract: An electronic shop sales system having an article storage device and an electronic shop interconnected through a network communication line for selling an article to a user terminal connected to the network communication line from the electronic shop, wherein, upon receipt of an order of an article from the user terminal, a storage condition for the article is read from the article database, an environment controller of the article storage device is operated based on the storage condition to adjust the storage environment in an article container, the ordered article is stored in the article container, and the article is delivered to the user by way of the article storage device.

Abstract: An ink-dot printer comprises a recording paper, at least one needle disposed in one side the recording paper and movable between a rest position remote from the recording paper and a projected position close to the recording paper, a driving mechanism for moving the needle between the rest position and the projected position, a driving control unit electrically connected to the driving mechanism so as to supply a driving control signal for controlling the movement of the needle to the driving mechanism, an ink supply mechanism adapted to supply ink to the distal end portion of the needle on the recording sheet side so that the ink attaches to the distal end portion when the needle is located in the rest position, an electrode disposed in another side of the recording paper and facing the distal end portion of the needle, and voltage control unit for applying between the needle and the electrode an ink flying voltage with respect to the supply of the driving control signal from the driving control unit to the

Abstract: An ink dot printer comprises a recording sheet, at least one needle made of an electrically conductive material and located in one side of the recording sheet so as to move between a normal position remote from the recording sheet and a projected position close to the recording sheet, a drive mechanism for displacing the needle between the normal position and the projected position, an ink supply mechanism for supplying and attaching ink to the tip of the needle which faces the recording paper when the needle is in the normal position, an electrode disposed on another side of the recording mechanism and facing the tip of the needle, and an electric field generating mechanism for generating, between the electrode and needle, an electric field of such intensity as to cause ink to fly from the tip of the needle, when the needle is closer to the recording sheet than the normal position, toward the recording sheet to thereby form an ink dot on the recording sheet.

Abstract: An ink-dot printer comprises a pair of slit forming members arranged to define a slit therebetween, an ink tank for storing ink in which the slit is immersed, a recording sheet opposed to the slit, a needle movable between a rest position and a projected position, a driving mechanism for moving the needle between the two positions, and an ink attracting unit for generating a magnetic or electric field in the slit, thereby attracting the ink from the ink tank into the slit to cause the ink to attach to the distal end portion of the needle located in the rest position, the ink attracting unit being adapted to generate an ink attracting magnetic or electric force of a necessary intensity for the ink to be attracted from the ink tank into the slit at the time of ink attraction, and to generate an ink holding magnetic or electric field of a minimum necessary intensity for a predetermined amount of ink to be held in the slit after the predetermined amount of ink is attracted into the slit, wherein the ink attaching
