Claim of US Patent No. 9,832,919

1. An electronic circuit component mounting head comprising:
a head main body;
a raising-lowering member which is guided on the head main body as to be capable of being raised and/or lowered;
a first raising-lowering driving device which raises and/or lowers the raising-lowering member with respect to the head main
body;

a component holding tool which holds an electronic circuit component and is held by the raising-lowering member as to be capable
of being raised and/or lowered relative to the raising-lowering member;

a second raising-lowering driving device which is raised and/or lowered together with the raising-lowering member by the first
raising-lowering driving device and which raises and/or lowers the component holding tool relative to the raising-lowering
member;

a biasing device provided between the raising-lowering member and the component holding tool, the biasing device biases the
component holding tool either up or down relative to the raising-lowering member; and

a stopper provided on the raising-lowering member,
wherein the second raising-lowering driving device engages with the component holding tool against a biasing force of the
biasing device without acting via an elastic member, and in that state, the second raising-lowering driving device mounts
the electronic circuit component on a circuit substrate,

wherein the stopper defines the upper raising limit or lower lowering limit of the component holding tool based on the biasing
force of the biasing device, and

wherein the second raising-lowering driving device separates the component holding tool, which contacts the stopper due to
the biasing force of the biasing device, from the stopper against the biasing force of the biasing device, and in that state,
the second raising-lowering driving device mounts the electronic circuit component on the circuit substrate.
