Imaging device including main-body-side loop antenna, tilt-side loop antenna and relay loop antenna
View Patent ↗To suppress an increase in a running cost while improving a transmission amount of information and reliability. Surveillance camera includes main body portion in which power supply board and data processing board are provided; pan portion that rotates in a pan direction with respect to main body portion; tilt portion that is provided with camera and rotates in a tilt direction with respect to pan portion; main-body-side loop antenna that is fixed to main body portion; tilt-side loop antenna that is fixed to tilt portion; and relay loop antenna that is fixed to pan portion and in which main-body-opposite-side loop portion opposite to main-body-side loop antenna and tilt-opposite-side loop portion opposite to tilt-side loop antenna are connected to each other in series.
1. An imaging device comprising:
a main body portion in which a power supply unit and a data processing unit are provided;
a pan portion that rotates in a pan direction with respect to the main body portion;
a tilt portion that is provided with a camera and rotates in a tilt direction with respect to the pan portion;
a main-body-side loop antenna that is fixed to the main body portion;
a tilt-side loop antenna that is fixed to the tilt portion; and
a relay loop antenna that is fixed to the pan portion and in which a main-body-opposite-side loop portion opposite to the main-body-side loop antenna and a tilt-opposite-side loop portion opposite to the tilt-side loop antenna are connected to each other in series;
wherein the main-body-opposite-side loop portion is fixed to a pan rotation shaft which is disposed so as to protrude into the inside of the main body portion, and
wherein the tilt-side loop antenna is fixed to a tilt rotation shaft which is disposed so as to protrude into the inside of the pan portion.
2. The imaging device of claim 1 ,
wherein the pan portion rotates integrally with the pan rotation shaft, and the main-body-side loop antenna and the main-body-opposite-side loop portion are oppositely disposed in parallel in a direction perpendicular to the pan rotation shaft, and
wherein the tilt portion rotates integrally with the tilt rotation shaft perpendicular to the pan rotation shaft, and the tilt-side loop antenna and the tilt-opposite-side loop portion are oppositely disposed in parallel in a direction perpendicular to the tilt rotation shaft.
