摘要:
A multi-beam photoelectric sensor is disclosed which can be fabricated by selecting the length of a light projection/light-receiving columnar member and the number and pitches of optical axes in accordance with the width of a hazardous area of an object or the diameter of the minimum object to be detected. A projector string or a photo-detector string includes an optical module string having an alignment of a plurality of optical modules with an optical system for one optical axis, a light projection circuit for one optical axis and a plurality of flip-flops corresponding to one stage of a shift register, integrated with each other, and a flat cable. The flip-flops in the adjacent optical modules are connected in cascade by the adjacent module conduction wires thereby to make up a shift register. The optical modules making the optical module string are sequentially activated by the data sequentially sent by the shift register.

In a light curtain generating device comprising a pair of pillar assemblies for supporting arrays of light emitting and receiving units which are placed opposite to each other so as to form a light curtain for detecting an object between the pillar assemblies, the light emitting and receiving unit arrays each consist of a group of single-beam optical modules so that the length of the arrays of light emitting and receiving units and the pitches of the individual light emitting and receiving units can be selected at will. Therefore, the light curtain generating device can readily adapt itself to each particular application at low cost and in a highly precise manner.

A screen printing apparatus includes a printing execution unit that performs screen printing on a substrate. At least one substrate support table that is provided movably along a specific direction orthogonal to the conveying direction. A table drive mechanism that moves the substrate support table at least between substrate entry and exit positions along a specific direction. The substrate entry and exit positions are set asymmetrically with respect to the specific direction. A printing execution unit drive mechanism is provided to drive the printing execution unit along the specific direction. A control unit is provided to control the printing execution unit drive mechanism so that the printing execution unit is driven to set the printing position on a substrate conveying path needed for the substrate support table to move from the substrate entry to the substrate exit.
摘要:
Disclosed is an inexpensive small-sized screen printing machine having low redundancy and high production efficiency and applicable to a dual conveying-type component mounting machine. The screen printing machine comprises a pair of substrate supporting tables provided to hold a respective substrate that is a print object and which is juxtaposed in a direction that is perpendicular to a conveying direction of the substrate, and a print executing section that performs a printing process alternately on the substrate held by the pair of substrate supporting tables. Due to the print executing section being driven in the direction under control of a control unit, a print position where the substrate supporting tables execute alternate printing is changed within a range in which one of the pair of substrate supporting tables and the other of the pair of substrate supporting tables oppose each other in the direction.

A component mounting apparatus includes: an operational sequence supervision unit which is created in compiler language determining an operational sequence specifying a series of sequence operations of suctioning, recognizing and mounting a component; and a second memory unit which stores a custom program, created in interpreter language and specifying an operation different from the series of sequence operations, and custom program designation information that designates execution of the custom program. The operational sequence supervision unit controls a switching process for switching from the series of sequence operations to an interpreter language processing execution routine for executing the custom program, during, or before or after, the series of sequence operations in accordance with the custom program designation information.

A recorder (100) comprises a non-contact charging module (160) that supplies power to a smart phone (200), a WiFi module (170) that communicates with the smart phone (200), and a microprocessor (130) that sends the smart phone (200) charging information indicating whether or not the non-contact charging module (160) is supplying power to the smart phone (200), upon receipt of an inquiry from the smart phone (200).
摘要:
A transmission control device generates, based on a content stream acquired from an external source, auxiliary information necessary for at least one of recording and playback of a content in the content stream and transmits a transmission target stream to an external device. The transmission target stream includes a first stream portion based on the content stream and a second stream portion based on the generated auxiliary information.
摘要:
A screen printing apparatus in which two printing units are provided in a production line which transports boards from a single board exit position set on a downstream side in a conveyance direction. One printing unit being disposed is available for set-up tasks while the other printing unit is working. Since set-up tasks can be conducted in one printing unit while the other printing unit is working, then it is possible to improve through-put dramatically even in cases where small-volume diverse-component production is carried out in a single lane.
