Abstract: A composite electronic component including a resonator element and a capacitor element fixed together by adhesive material. The capacitor element is longer than the resonator element, so that side steps are defined on both end portions of the elements. First and second lead terminals are connected by solder with first and second capacitor electrodes located on a front surface of the capacitor element and with resonator electrodes located on side surfaces of the resonator element exposed at the side steps. A third lead terminal is connected by solder with a third capacitor electrode located on a rear surface of the capacitor element. Therefore, the thin and miniature composite electronic component adapted for a Colpitts oscillation circuit is obtained at a low cost.

Abstract: A component supply method includes the steps of sticking an adhesive sheet, which is provided on its upper surface with a first foam releasable adhesive layer whose adhesion, can be reduced by heating, onto an upper surface of a pallet having a side surface serving as a reference portion, sticking a wafer onto the upper surface of the adhesive sheet, cutting the wafer for obtaining a number of components, reducing the adhesion of the first adhesive layer by heating, and taking out the individual components, obtained by cutting the wafer, from the pallet. In the steps of sticking the adhesive sheet, sticking the wafer and taking out the components, the elements are located on the basis of the side surface of the pallet serving as a reference portion.

Abstract: Retainer grooves are formed widthwise at a constant pitch on the external surface of a timing belt to retain the lead terminals of an electronic component therein. A magnet is mounted to a rail for guiding the timing belt to attract the lead terminals of the electronic component to the retainer grooves. The electronic component can be prevented from falling off or being displaced due to an inertia force generated at the time of intermittent feed so as to be stably conveyed not only horizontally but also in vertical or circular arc directions.

Abstract: An apparatus for automatically taping electronic components arranged such that when a timing belt retaining lead terminals of electronic components in its retainer grooves is engaged with a toothed pulley of a first rotary drum, the lead terminals are lifted to be transferred from the timing belt to the first rotary drum. The electronic components are transferred from the first drum to a third rotary drum via a second rotary drum being retained by their retainer teeth. A base tape is fed to the periphery of the third rotary drum and an adhesive tape is applied on the base tape, thereby fixing the lead terminals.
