Abstract

A fishfinder in which signal transmission is conducted between a reception antenna formed on a display rotation plate and a transmission antenna formed on a connection plate, both the reception antenna and the transmission antenna being opposed each other, and electric power transmission is conducted between a pair of inductive coupling coils, one being formed on the display rotation plate and the other being formed on the connection plate so as to oppose each other.

Claims

1. A fishfinder of flasher type comprising:

a front case in which a transparent display window is formed;

a motor with a rotation shaft arranged on a main plate;

a display rotation plate fixed to the rotation shaft of the motor, the display rotation plate being disposed opposite to the display window;

a first inductive coupling coil formed around a rotation shaft part of the display rotation plate;

a second inductive coupling coil formed around a hole to insert the rotation shaft of the motor, the hole being formed in a connection plate;

a display LED fixed on the display rotation plate at a position opposite to the display window of the front case;

a reception antenna arranged on a circumference of the display rotation plate; and

a transmission antenna arranged on a circumference of the connection plate, the transmission antenna being opposite to the reception antenna on the display rotation plate.

2. The fishfinder of flesher type according to claim 1, wherein both the transmission antenna and the reception antenna are formed from metallic material.

3. The fish finder of flasher type according to claim 1, further comprising a timing detection part,

wherein the timing detection part includes a light emission element fixed to the display rotation plate and a light reception element fixed to the connection plate, the light emission element and the light reception element being arranged so as to oppose each other.
