发明名称 Handset detection device for use in telephones
摘要 A handset detection device for use in telephones comprises a movable member 2, a circuit board 4, a detector 5, and a cushioning member 3. The movable member 2 has a concave portion 28 on a contact surface 2A, in which the cushioning member 3 is so fitted as to protrude toward the circuit board 4 by a predetermined amount. When the movable member 2 is rotated toward the circuit board 4 upon placement of a handset 8 onto a handset holding base 9, the cushioning member 3 is deformed by the contact with the circuit board 4 to reduce the moving speed of the movable member 2. The movable member 2 is then stopped by making the contact surface 2A come into contact with an upper surface 4A of the circuit board 4. Accordingly, the movable member 2 can be stopped at a predetermined position, whereby to prevent detection failure by a detection sensor 31 in connection with the movable member 2, achieving a precise detection.
