Description

  The present invention relates to a monitor panel device that reduces vibration of a monitor panel.

  Some monitor panel devices including a liquid crystal monitor panel or the like have a liquid crystal monitor panel movable with respect to the device main body, such as a car navigation system. In such a monitor panel device, there is a model in which the monitor panel is opened and closed by sliding an upper fulcrum of the monitor panel in a groove on the device main body side. In such a model, the slider mounted on the apparatus main body and driven back and forth is connected to the lower fulcrum of the monitor panel, and the upper fulcrum of the monitor panel slides in the groove in conjunction with the movement of the slider.

  However, in order for the upper fulcrum of the monitor panel to slide without smoothly twisting the groove on the apparatus main body side, it is necessary to provide a margin (backlash) between the upper fulcrum of the monitor panel and the groove. When an external force such as vibration due to the engine rotation or road surface reaction force during traveling is received, there is a problem that it becomes a cause of abnormal noise.

  In order to reduce such backlash, a technique is considered in which a spring force is applied to the monitor panel. For example, Patent Document 1 discloses a device in which a tension roller is interposed between a panel on the apparatus main body side and a monitor panel. Further, although the upper fulcrum is not moved along the groove, there is one disclosed in Patent Document 2 in which the monitor panel is urged by a spring.

Japanese Patent No. 3426474 Japanese Patent No. 3922616

  However, the one described in Patent Document 1 and Patent Document 2 is not designed to absorb the play of the upper fulcrum itself, and in the one described in Patent Document 1, the tension roller is installed and the force is adjusted. There are also problems such as being difficult. Further, in the case of a monitor panel provided with an operation switch, the one described in Patent Document 1 and Patent Document 2 has a problem such as rattling when the operation switch is pressed because the biasing direction is opposite to the operation switch pressing direction. .

  The present invention has been made in view of such a technical situation. The backlash between the fulcrum on the monitor panel side and the guide surface on the apparatus body side is eliminated, and not only when the monitor panel is closed but also in a predetermined state. It is an object of the present invention to prevent rattling from occurring even in the tilted state and to prevent rattling from occurring when the operation switch is pressed.

The monitor panel device according to the present invention is a monitor in which a monitor panel is disposed at a front portion of the apparatus main body, and the lower portion of the monitor panel is pushed forward by a driving means provided in the apparatus main body so that the monitor panel can be tilted. In the panel device, a guide surface facing the device body direction and the monitor panel direction is provided on the front side surface of the device body, and a guide roller that contacts the guide surface facing the monitor panel direction is provided on the side surface of the monitor panel. A rubber roller is provided coaxially with the guide roller, a rubber roller contact surface on which the rubber roller is elastically contacted is formed on a side facing the guide surface facing the apparatus main body, and the rubber roller is in contact with the rubber roller contact surface. The guide roller is pushed against the guide surface facing the monitor panel by the rubber elastic force generated by elastic deformation. A kicking configuration, the slider is moved in the longitudinal direction by the drive means is pivotally mounted on the lower side of the monitor panel, and mounting the monitor panel coil torsion spring pivot point to the lower side of the slider, the The torsion coil spring urges the monitor panel in the direction of pressing the guide roller against the guide surface facing the monitor panel .

  According to the monitor panel device of the present invention, when the monitor panel moves and when the monitor panel is stopped at a predetermined angle, the guide roller faces the monitor panel direction by the rubber elastic force due to the deformation of the rubber roller. Since it is pressed against the guide surface, backlash between the guide roller and the guide surface is absorbed, and even if the monitor panel device receives external force such as vibration, the monitor panel does not rattle and generate abnormal noise. Further, even when an external force such as pressing an operation switch is applied, there is no rattling. Further, the guide panel and its guide surface are made of metal, whereby the guide panel can be grounded.
