Abstract
In a circuit device of this invention, a support base member, which holds an electronic component and circuit for supplying a control signal to a rotating carriage, is formed integrally with a carrier member via a plurality of cutting areas which are to be cut out from the carrier member, in order to provide an FPC, connected electrically to the carriage, with such a height which enables the FPC to be displaced on a same plane as a plane in which the carriage rotates or a plane parallel to the plane in which the carriage rotates. The cutting area is folded and overlapped at a predetermined position in a state in which the support base member is cut out by punching so as to provide a predetermined height.
Claims16
An information recording and reproducing unit comprising:
- a head unit configured to record information into a disc-like recording medium and reproducing information from the recording medium;
- a carriage member which positions the head unit at an arbitrary position in the radius direction of the recording medium;
- a carriage drive unit which changes the position of the carriage member;
- a carriage drive circuit which supplies a control signal for changing the position of the carriage member to the carriage drive unit;
- a connecting medium which connects the carriage drive unit with the carriage drive circuit such that the control signal can be supplied from the carriage drive circuit to the carriage drive unit;
- and
- a support base member which supports the carriage drive circuit and the connecting medium in such a predetermined positional relation that a displacement of the connecting medium with a change in position of the carriage member does not affect the position of the carriage member.
A circuit device comprising:
- a support base member for holding a circuit board for controlling a displacement originating from a rotation of a control object component and electronic components;
- and
- a connecting medium which connects electrically the control object component with the support base member and when the control object component rotates, is capable of being displaced on a same plane as a plane in which the control object component rotates or a plane parallel to the plane in which the control object component rotates, wherein
- the support base member is formed integrally with a carrier member via a plurality of cutting areas which are to be cut out from the carrier member and folded and overlapped at a predetermined position in a state in which the support base member is cut out by punching, thereby providing such a height which enables the connecting medium to be displaced on a same plane as a plane in the carriage member rotates or a plane parallel to the plane in which the carriage member rotates.
