A pivotal lever has a first therapeutic member and a second therapeutic member positioned below the first member, for the members to grip and knead the shoulder of the person to be massaged as by the fingers of the acupressurist. A massage unitcomprises a pair of left and right pivotal leverspivotally movably arranged on a chassis, and a first therapeutic memberand a second therapeutic memberarranged on each of the pivotal leversand movable toward and away from each other. The first and second therapeutic membershave motion conversioncoupled thereto for converting the pivotal movement of the pivotal leverinto the movement of the first and second therapeutic memberstoward and away from each other. The first and second therapeutic membersgrip the shoulder of the person when moved toward each other and release the shoulder from the gripping action when moved away from each other to thereby cause the members to simulate the gripping and kneading movement of the acupressurist.

In an external force measuring system comprising a piezoelectric element 61 or producing a charge when acted on by an external force, and a charge amplifier 7 chargeable with a variation in the charge produced by the piezoelectric element to output a voltage signal, the charge amplifier 7 comprises a feedback loop having an on-off controllable switch 8 connected in parallel therewith. The switch 8 is on-off controlled by a comparator 81 for comparing the output voltage with a reference value and is closed while no external force acts on the element.

External force measuring system and component mounting apparatus

An apparatus for mounting electronic components on the surface of printed boards by a suction head assembly 4 coupled to a head lift mechanism comprises a force sensor 6 for measuring the pressure exerted on the component by a mounting operation, and a microcomputer 1 for preparing a control signal in accordance with the deviation of the value measured by the force sensor from a desired value of pressure on the component. The rotation of a head lifting motor 51 is controlled based on the control signal.
