The exterior view inspecting apparatus for circuit board of the invention including a sensor unit for emitting a laser beam to an object to be inspected, and detecting the displacement of the object by focusing the reflected light on a photoelectric transducer by using a receiving lens; an optical path converter unit for refracting the optical path of the laser beam; a sensor head unit incorporating the sensor unit and optical path converter unit; a control unit for moving the sensor head unit along a specified scanning route; a correction unit for correcting the displacement data of the object to be inspected as detected by the sensor unit, and a judging unit for judging the existence and position of an electronic component on a circuit board from the corrected displacement data. The optical path converter unit includes a flat sheet glass inclined relative to the optical path of the laser beam, rotating about the axial center parallel to the optical path. By this optical path converter unit, the optical path of the laser beam is refracted so that the laser beam scans the circuit board drawing a small circular trace. As the trace draws a small circle, the trace detects the end portion of the electronic component on the circuit board multiple times. Consequently, the existence and position of the electronic component on the circuit board can be detected accurately.

A compact and high-speed automatic electronic parts mounting apparatus is provided which includes first and second parts feeders, first and second mounting heads, a printed board-holding table, and a controller. Each of the first and second parts feeders includes a plurality of cassettes storing therein electronic parts and having pick-up stations. The second parts feeder is arranged at a preselected interval away from the first parts feeder in a first direction. Each of the first and second mounting heads is movable in the first direction and includes a plurality of pick-up nozzles movable in a vertical direction for picking up the electronic parts from the pick-up stations of the cassettes. The printed board-holding table is disposed within the preselected interval between the first and second parts feeders so as to move in a second direction perpendicular to the first direction. The controller controls the movement of the table and the first and second mounting heads so that the first and second mounting heads pick up the electronic parts from the cassettes of the first and second parts feeders, respectively, and mount them on a printed board held on the table in sequential mounting operations.

An apparatus capable of supplying electronic components successively to a loading position of an electronic component mounting machine at a high speed and in a stable manner is disclosed, in which a dancing guide is operatively connected with a feeding unit for taking out a predetermined length of the electronic-component tape from a supply reel before feed pins of the feed unit advance a carrier tape of the electronic-component tape to move a leading one of the electronic components into the loading position. Preferably, the apparatus further includes a separating unit, operatively connected with the feed unit, for separating an adhesive tape from the leading electronic component and the carrier tape before said feed pins advance the carrier tape. The separating unit is composed of a pair of spaced movable guide rollers and a fixed guide roller.

To provide a drum pedal with a suppressed deflection and no fluctuation in beat timing or beat force of a beater, which allows the player to perform with a desired well-modulated tone, and to obtain the direct feeling, which is a sense of the depressing force being directly transferred to the beater attained by the good operability and the maintained stable attitude of the entire pedal, without inviting an increase in weight or material cost.A drum pedal includes at least: a pedal frame 2 having a base portion 20, a right and left pair of strut portions 21 and a heel portion 22; a rotation shaft 3 to which a beater 5 that beats a drumhead is mounted, and that is horizontally pivotally supported between respective top end portions 21a of the strut portions 21; and a foot board 4 that has its base end side rotatably supported by the heel portion 22, and that rotates the rotation shaft 3 through a coupling member 40 extending from its tip end side in accordance with the depressing operation of the player.

The component mounting apparatus includes a component delivery unit, a chuck (13) provided on the component delivery unit, a component transfer unit (19) for receiving a component held by the chuck (13), and a head (20) for receiving the component held by the component transfer unit (19). The head (20) includes a main head body (80), a vertically moving mechanism (81) for the main head body (80), insertion nails (68) provided at a bottom portion of the main head body (80), an opening/closing mechanism (82) for the insertion nails (68), and a turning mechanism (83) for moving the insertion nails (68) in forward and backward directions. A cam plate (84) constituting the turning mechanism (83) is mounted detachably on the main head body (80).

Intended is to provide a strainer having a switch mechanism, which is hardly rattled by a wear, which can be stably operated by a weak force, which does not load a snare assembly and which can maintain an excellent operation feel, and a snare assembly holding structure which has a reliable clamping force so that it can prevent the looseness of the snare assembly end portion. An operation lever is hinged on its base end side to a base body. A link is turnably connected on its one end side to the lower side portion of a snare assembly holding member, and is likewise turnably connected on its other end side to a midway position of the operation lever. When the operation lever turns upward, the snare assembly holding member is pulled upward through the link. When the operation lever turns downward, the snare assembly holding member is pushed downward.
