Description

  The present invention relates to a panel drive device that drives a movable nose that covers a front panel disposed on the front surface of a main body device of an in-vehicle device such as a car audio.

  In an in-vehicle audio device such as a cassette tape player or a CD player, various operation keys, a display unit, or a media insertion port are provided on the front panel attached to the front surface of the main unit. Since the size of the display section has increased and the number of operation keys has increased, it has become difficult to dispose all of the display section, operation keys, media insertion slot, and the like in a limited space on the front panel. It was.

  To solve this problem, a media insertion slot is provided on the front panel, a display unit and various operation keys are provided on a movable nose that covers the front panel, and the movable nose is mounted on the slide member. By rotating the movable nose in conjunction with the reciprocating operation, the media insertion port arranged on the front panel can be closed with the movable nose, or can be opened with the media insertion port exposed. It is configured.

  When the slide member is retracted to the retracted position as seen from the operator, the movable nose is in an upright state, and the media insertion port located behind the movable nose is covered with the movable nose. When the slide member is moved from the retracted position to the advanced position, the movable nose rotates around the rotation fulcrum and the lower end protrudes toward the near side, and the media insertion port is rotated along with the rotation of the movable nose. Is exposed.

  According to such a movable nose type panel drive device, the entire surface of the closed movable nose can be used as a display area or a key operation area, and the movable nose is rotated only when a medium is inserted or ejected. Since the mouth only needs to be exposed, there is an advantage that a relatively large display portion and many operation keys can be arranged in a limited space. However, on the other hand, when the movable nose rotates, the interference between the movable nose and the front panel becomes a problem.

  In relation to this problem, for example, the movable nose is configured to rotate around the guide pin by moving back and forth together with the slide member. In order to avoid contact between the movable nose and the front panel or the like provided in the opening of the main unit due to drawing a trajectory that enters the inside of the main unit opening, the upper and rear surfaces of the movable nose are notched. As a means to solve the problem that circuit boards and circuit elements housed inside the movable nose are greatly restricted, it is connected to the movable nose and the lower fulcrum of the movable nose so as to be able to rotate freely. A slide member, a driving means for moving the slide member in the front-rear direction of the main body device, an arm rotatably connected to the upper fulcrum of the movable nose, A power transmission mechanism interposed between the arm and the slide member, and in the process of moving the slide member from the retracted position to the advanced position, the arm is advanced substantially integrally with the slide member, On the other hand, there is a technique for moving the slide member relatively forward (see, for example, Patent Document 1).

  However, in the panel driving device configured in this way, the position is determined by the rotation fulcrum pin provided on the arm being sandwiched between the groove of the slide member and the groove of the power transmission mechanism. When the backlash of the pivot fulcrum pin becomes large, the arm is easily twisted.As a result, when the posture of the arm and the movable nose becomes unstable with respect to the vibration of the movable nose being driven or from the outside, Interference may cause abnormal noise. Further, since the rotation fulcrum pin of the arm is not supported by the immovable member, there is a concern about the strength effect over time.

  An object of the present invention is to solve the above-described problems, and to provide a panel driving device that reliably avoids interference between a movable nose and a front panel and enables a stable opening and closing operation of the movable nose. .
