ジエクト装置。[Scope of Claim for Utility Model Registration] In an ejection device for an in-vehicle audio device that detects the off state of the ignition key and controls an ejection mechanism to perform an eject operation, the ACC. ACC. detects the change from on to off of the switch.
a switch change detection circuit; a battery voltage change detection circuit that detects a voltage drop in battery voltage when starting the engine; and an ACC. The switch change detection circuit is ACC. If the battery voltage change detection circuit does not detect a voltage drop in the battery voltage within a predetermined time after detecting the change of the switch from on to off, it outputs an eject control signal, and the ACC. The switch change detection circuit is ACC. and an eject control circuit that does not output an eject control signal when the battery voltage change detection circuit detects a voltage drop in the battery voltage after detecting a change from on to off of the switch. Eject device for in-vehicle audio equipment.
