ELECTRONIC APPARATUS WITH MOVABLE UNIT SUCH AS DISPLAY UNIT MOVABLE IN OPENING AND CLOSING DIRECTION

摘要

An electronic apparatus which prevents a moving state of a movable unit such as a display unit from being falsely detected. The movable unit is movable in an opening and closing direction with respect to an apparatus main body. When the movable unit is moved with respect to the apparatus main body, a magnetic sensor in the apparatus main body detects a moving state of the movable unit with respect to the apparatus main body by detecting a magnetic field generated by a magnetic field generating unit provided in the movable unit. A Hard Magnetic Material is placed inside the apparatus main body and at such a location that the magnetic sensor is sandwiched between the Hard Magnetic Material and the movable unit being in a closed state. A Soft Magnetic Material is placed inside the apparatus main body and between the magnetic sensor and the Hard Magnetic Material.
