[Prior art]

 The shaping of the interior of a vehicle such as a passenger car varies depending on the type of vehicle. As a standard for controlling the size of electrical equipment mounted in such a vehicle, there is the DIN standard generally used by audio manufacturers. Modern car audio equipment is generally designed based on this DIN standard, and one or two 1DIN (180mm width x 50mm height when viewed from the front) size mounting space is provided inside the vehicle. It is prepared. In-vehicle liquid crystal display devices that can be installed in the DIN space have been commercialized, but the position of the DIN space varies depending on the vehicle model, and in many cases, it is set on the console box in front of the shift knob for gear shifting operation. Has been done. A technique for incorporating a liquid crystal display device in a DIN space of the console box so that the liquid crystal display device can be retracted and retracted is known from JP-A-3-273944. In such a vehicle-mounted liquid crystal display device, the image screen is directed downward when the image screen is directed downward by a sliding operation so that the image screen is rotated and raised upward.

[Problems to be solved by the device]

 As described above, the on-vehicle liquid crystal display device that can be retracted into and from the storage portion has been commercialized, but the mounting position thereof is limited depending on the vehicle model. Therefore, depending on the vehicle model, the liquid crystal display device may collide with the shift knob when it is projected by sliding and cannot be used. In order to avoid this, it is necessary to take measures such as protruding the liquid crystal display device at a position where the shift knob is displaced (for example, in the case of an AT (Automatic Transmission) vehicle, the parking position is returned to the neutral position). To do. However, even if the LCD is accidentally extended, it will hit the shift knob. In particular, if the liquid crystal display device is made to project by a motor drive, the external appearance of the device will be damaged and the electric motor and the gears that make up the drive mechanism will be burdened, resulting in failure. . In order to avoid this, a special protection mechanism is required, such as, for example, configuring a drive device for sliding operation so that a limiter works for sliding, or creating a sequence for automatic reversing operation on a microcomputer. And it becomes expensive.

Therefore, an object of the present invention is to install and retract a vehicle-mounted liquid crystal television, etc., which is assembled in a console box and can be freely retracted by driving a motor, by directly touching the main body of the device so that a special protection mechanism is provided. It is an object of the present invention to provide an in-vehicle image display device capable of protecting a drive device including an apparatus main body and an electric motor by automatically performing a reversing operation when an obstacle is hit without requiring the above.

[0005]
