摘要:
A robot control apparatus for controlling the movement of an arm (7) of a robot (6) with respect to a workpiece (2) transported upon a pallet (1) moving down an assembly line, wherein the position of the arm of the robot is compensated for in accordance with the position of the workpiece. A reference position memory stores a reference position of one of the pallet and workpiece. A position detector (16, 17) detects the position at which the pallet of workpiece is clamped along the assembly line. A difference between the outputs from the reference position memory and the position detector is used to correct a value stored in a work position memory to thus provide the output data which controls the movement of the arm of the robot.

A head for an industrial robot comprising, a head body mounted on an end of an arm of said industrial robot, an internal motor, a nut member and a guide member rotatably supported by said head body, a belt drive device provided between the motor and the nut member, a screw rod passing through and threadedly engaging with the nut member, a spline shaft having at a lower end an operating chuck, a connecting device for connecting the screw rod and the spline shaft to each other in a sealable manner and slide members for preventing rotation of the screw rod. A fluid is supplied to operate the chuck through passages formed in the screw rod and the spline shaft.
摘要:
A process for controlling an industrial robot (1) in which most data for controlling the robot can be supplied using a preset process without moving the robot (1) and only data for regions in which very precise control is required need be prepared by actually moving the robot (1). A programming unit (2) is provided separate from but connectable to a robot control unit (3). The programming unit (2) is used to compile and transfer completed programs to the robot control unit (3) for controlling the movements of the robot (1). To program the robot control unit (3), the programming unit (2) and robot control unit (3) are connected as an on-line system. Then, data describing a desired path of movement is inputted to the programming unit as a series of coordinates in Cartesian form. in regions where very precise control is required, the coordinates describing the desired path of movement are corrected using small corrective motions of the robot. The inputted data and the corrected coordinates are displayed.

A structure of a card gate mechanism in a card reader of, e.g., an ATM (automated teller machine). In order to constitute a gate opening (3) of a card gate mechanism (1), a gate frame (4a, 4b) which includes a wide-open portion (5) which leads a card (2) to a card carrying path (14) by using a material which transmits light is provided on at least one surface side of the card (2), and a light source portion (6) which irradiates the gate frame (4a, 4b) with the light is provided, thereby causing the wide-open portion (5) to shine by emitting the light from the light source portion (6). In this case, when a part of the gate frame (4a, 4b) is formed as a lens portion (9), a direction of light irradiation can be controlled, thereby alleviating irregularities in an element.

A non-contact type IC medium and a read/write system using this medium, and a technique of improving the reliability and the security of them. In the non-contact IC medium, three or more non-contact type IC chips (1) each having an information storage portion and at least one antenna (2) which transmits and receives data in the non-contact manner are arranged at positions enabling reading and writing at the same time, and divided data of data to be recorded and error correction data used to restore the divided data which has failed to be read by the read divided data are recorded in all or a part of the three or more non-contact type IC chips (1).
摘要:
A card transporting mechanism for a card reader in which the trailing end of a card (1) as viewed in a card transporting direction is brought into contact with a first card engaging/holding member (2) moving in a card transporting direction, and the card (1) is transported by said first card engaging/holding member (2), said card transporting mechanism including a carriage (3) movable in the card transporting direction, said first card engaging/holding member (2) being mounted on such that said first card engaging/holding member (2) is movable between a first position where said first card engaging/holding member (2) comes in contact with the trailing end of said card (1) and a second position where said first card engaging/holding (2) member does not comes in contact with said card (1), and a transportation drive member, for transporting the card, coupled to said first card engaging/holding member (2) such that a position of said first card engaging/holding member (2) changes in accordance with a moving direction of said transportation drive member, and when said card (1) travels in a first direction, said first card engaging/holding member (2) is located, by said transportation drive member, at a position where said first card engaging/holding member (2) comes in contact with the trailing end face of said card (1), and said card (1) is transported by moving said carriage (3).
