Image pickup apparatus

1. An image pickup apparatus configured to detect a vibration comprising:

a grip configured to project toward an object side in an optical axis direction in an imaging optical system;

a rear exterior member located on a rear side which is opposite to the object side;

at least one processor or circuit configured to perform the operations of a display unit;

the display unit located on the rear side further than the rear exterior member and configured to display an image;

a hinge mechanism configured to support the display unit rotatably relative to the image pickup apparatus;

a first substrate located on the object side further than the rear exterior member and including a control element configured to control the image pickup apparatus;

an angular velocity detector configured to detect an angular velocity of a vibration in the image pickup apparatus;

a second substrate located on the object side further than the first substrate and having the angular velocity detector; and

a holder configured to hold the angular velocity detector, on a side opposite to the grip with respect to an optical axis in the imaging optical system viewed from the optical axis direction and on the object side of a space formed between the first substrate and the rear exterior member in the optical axis direction,

wherein the second substrate includes a buffer member configured to relax a vibration and is held by the holder via the buffer member;

wherein a reinforcing member made of a metallic material is formed so as to cover a mounting area of the angular velocity detector on a surface of a side of the buffer member of the second substrate,

wherein the buffer member is formed so as to cover the mounting area of the angular velocity detector on a surface of a side of the reinforcing member of the holder,

wherein the buffer member, the reinforcing member, and the second substrate are laminated in a three-layer structure in order from a side of the first substrate,

wherein a first positioning member for positioning the second substrate on the holder is provided in an area of the three-layer structure, and

wherein a second positioning member for positioning the second substrate on the holder is provided in an area other than the area of the three-layer structure.

2. The image pickup apparatus according to claim 1 , further comprising:

a memory connector connectable with a memory configured to store an image; and

a battery configured to supply a power to the image pickup apparatus,

wherein the control element, the memory connector, and the battery are arranged on a side on which the grip is provided when viewed from the optical axis direction.

3. The image pickup apparatus according to claim 1 , wherein the angular velocity detector is arranged outside a projected area of the image sensor when viewed in the optical axis direction.

4. The image pickup apparatus according to claim 1 , wherein the control element sets an imaging condition based on a signal value output from the angular velocity detector.

5. The image pickup apparatus according to claim 4 , wherein the imaging condition contains at least an exposure time of the image sensor.

6. The image pickup apparatus according to claim 1 ,

wherein the first positioning member is detached from the holder after the second substrate is assembled to the holder, and

wherein even after the second substrate is assembled to the holder, the second substrate and the holder are press-fitted by the second positioning portion.
