In the figure, the pulley support means 11 is mounted on a base 12 which is fixed to the table body 5 which provides a slide base for the cradle 3. The base 12 has the same longitudinal direction as the cradle 3, and has a smooth contact surface with the pulley support means 11. The pulley support means 11 can thus slide on the base 12 in the longitudinal direction of the cradle 3. The spiral spring 13 is connected to the edge of the sliding surface of the base 12 (
The pulley support means 11 is fixed to the rear end of the cradle 3 and connected to the pulley support means 11 via a wire 14.

Pulleys 15, 16 and 17 are installed and cables 18, 19 and 2o are wound around each pulley. One end of each cable is fixed to the tip of the cradle 3, and one end of this cable is connected to the coil 1 or audio equipment (not shown) installed at the tip of the cradle 3 using a dedicated connection cable. be exposed. On the other hand, the other end of each cable is connected to an external circuit (not shown) such as a transmitting/receiving section and an audio circuit.

円滑に行われる。In the above configuration, when the cradle 3 is moved in the longitudinal direction, one end of each cable fixed to the tip of the cradle 3 moves in the same manner as the cradle 3 moves. On the other hand, the other end of each cable is fixed to the tip of the base 12. Further, the pulley support means 11 (pulley) is pulled toward the rear end of the cradle 3 by a spiral spring 13. Therefore, when the tip of the cradle 3 is inserted into the magnet part 2, each pulley and the pulley support means 11 are pulled by each cable and move linearly in the same direction as the cradle 3. Further, when the cradle 3 is moved in the direction in which it is not pulled out from the magnet part 2, each pulley and the pulley support means 11 are linearly pulled back toward the rear end side of the base by the action of the spiral spring 13. During this operation, each cable is wound around each pulley and follows the movement of the cradle without interfering with each other. This allows the cables 18, 19 and 20 to be smoothly ticked up.

Further, instead of the spiral spring, a motor or a spring of another shape may be used to constitute the pulling back means for the pulley support means.

簡単になる。(Effects of the Invention) As explained above, according to the tick-up device of the present invention, the tick-up device is installed in a table so as to be movable in the same direction as the cradle, and is pulled in the opposite direction to the fixed position of the cable. Since the pulley support means coupled to the return means is provided, and the pulley is installed on the pulley support means and the cable is wound around the pulley support means, the pick-up device can be configured within the table. Therefore, the space factor is improved. Furthermore, since only one pulley is required per cable, the configuration is simplified.
