Camera head and camera device
View Patent ↗Provided is a camera head capable of further size reduction. A camera head of a camera device is provided with an imaging unit having three image sensors, a flexible substrate connected to the three image sensors, and a chassis in which the imaging unit is accommodated and on which the flexible substrate is mounted. The three image sensors are provided on the upper face side, the rear face side, and the lower face side of the imaging unit, respectively, and the flexible substrate is arranged on the transverse face side of the imaging unit on which the image sensors are not provided in the chassis.
1. A camera head comprising:
an imager having three image sensors;
a flexible substrate connected to said three image sensors; and
a chassis in which said imager is accommodated and on which said flexible substrate is mounted, wherein
said three image sensors are provided on an upper face side, a rear face side, and a lower face side of said imager, respectively, and
said flexible substrate is provided with a first rigid portion on which a first electronic component is mounted and a second rigid portion on which a second electronic component having a heat generation amount larger than that of said first electronic component is mounted;
said chassis is provided with a partition wall which divides an inside of said chassis into a front-side space and a rear-side space;
said imager is accommodated in said front-side space;
said first rigid portion is mounted on a said side wall of said chassis on a transverse face side of said imager in said front-side space; and
said second rigid portion is mounted on said partition wall in said rear-side space.
2. The camera head according to claim 1 , wherein
said imager has a prism in which said three image sensors are provided on an upper face side, a rear face side, and a lower face side, respectively;
a prism base plate for fixing said prism to said chassis is provided on one of transverse face sides of said prism; and
said flexible substrate is arranged on an other transverse face side of said prism on which said prism base plate is not provided.
3. The camera head according to claim 1 , further comprising:
a substrate holder on which said flexible substrate is mounted, wherein
said substrate holder is provided with a substrate holding portion which locks and holds said flexible substrate and a locking portion which is locked by a locked portion provided on said chassis; and
said flexible substrate is mounted on said side wall of said chassis through said substrate holder.
4. The camera head according to claim 1 , wherein
said first rigid portion is mounted on said side wall through a first radiation sheet; and
said second rigid portion is mounted on said partition wall through a second radiation sheet.
5. A camera device comprising:
the camera head according to claims 1 ; and
a controller to which said camera head is connected through a cable.
