Abstract

PURPOSE:To display a normal picture on a monitor by fixing a fixing base for a printed circuit board mounting a lens, a lens supporting body and an image pickup element on itself to the bottom of a case body forming a through hole for the lens supporting body so as to be optionally rotated. CONSTITUTION:The printed circuit board 2 mounting the lens 3, the lens supporting body 4 and the image pickup element 1 is fixed to the disc-like base 9 forming ring-like holes 10. The base 9 is fixed to a case bottom plate 7 so as to be optionally rotated by engaging a projected part formed on the side face of the base 9 with a recessed part formed on the center part of the case body 6. A hole 8 into which the supporting body 4 can be rotatably penetrated and screws 11 to be penetrated into the holes 10 are formed on the case body 6 and nuts 13 are engaged with the screws 11 penetrated into holes 12 formed on the bottom plate 7 and the holes 10. Consequently, an image pickup part consisting of the lens 3, the element 1, etc., can be optionally rotated by loosening the nuts 13 without being restricted by the fixing position of the body 6 to display a normal picture and then fixed by the nuts 13.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted camera.

[0002]

2. Description of the Related Art In recent years, in the field of car electronics, increasing the safety of vehicles has become a serious issue. As one means for solving this problem, it has been attempted to eliminate a blind spot of a vehicle, and therefore, a vehicle-mounted camera has been introduced.

A conventional vehicle-mounted camera will be described below with reference to the drawings. In FIGS. 5 and 6, 1 is a solid-state image sensor, which generates an electrical signal corresponding to the imaged light. Reference numeral 2 denotes a printed wiring board to which the solid-state image pickup device 1 is attached and a circuit for processing the output signal of the solid-state image pickup device 1 is wired. Reference numeral 3 is a lens, and an image to be picked up by focusing the lens 3 combines the image with the solid-state image pickup device 1. A lens support 4 fixes the lens 3 inside the housing, and one end of the lens support is fixed to the printed wiring board 2. Further, the inside of the lens support 4 has a structure through which light that has passed through the lens 3 can pass in order to couple an image to the solid-state image sensor 1. The solid-state imaging device 1, the printed wiring board 2, the lens 3, and the lens support 4 which are integrated as described above are referred to as an imaging unit 5. Reference numeral 6 denotes a case main body that protects the image pickup unit 5, and reference numeral 7 denotes a case bottom plate fixed to the case main body with screws or the like. Further, a hole 8 is provided in the case body so that the lens support 4 penetrates.

Further, the lens 3 is fixed to the lens support 4, the lens support 4 is fixed to the printed wiring board 2 to form the image pickup section 5, and the printed wiring board 2 of the image pickup section 5 is It is fixed to the case bottom plate 7 with screws or the like.

In the vehicle-mounted camera as described above, an image of a subject existing in the direction in which the solid-state image pickup device 1 is oriented by focusing the lens 3 is combined with the solid-state image pickup device 1, and the solid-state image pickup device is formed. The output signal of 1 was displayed on a monitor or the like.

[0006]

However, in such a method of fixing the image pickup portion of the vehicle-mounted camera, the image pickup portion cannot be rotated. For example, as shown in FIG. If it is installed at an angle of 22,
The subject 24 is projected on the monitor 23 in an inclined manner, which makes the image very difficult for the user to see.

As described above, when there is no degree of freedom in the rotational position of the image pickup unit, in order to display a normal image on the monitor, the vehicle-mounted camera must be used in an upright position. There was a problem that the mounting position of was limited.

The present invention solves such a problem and is capable of displaying a normal image on the monitor without being restricted by the mounting position of the vehicle-mounted camera.

[0009]

In order to achieve this object, a vehicle-mounted camera according to the present invention comprises a substrate on which a solid-state image pickup device is mounted, a solid-state image pickup device of the substrate mounted at one end, and a lens inside. A lens support that is supported and is capable of coupling an image of a subject to a solid-state image sensor through the lens, a case bottom plate to which the substrate is mounted, and the case bottom plate to accommodate the substrate, and And a case main body having a hole through which the lens support penetrates, and the substrate is rotatably attached to the case bottom plate.

[0010]

With such a structure, the image pickup section can be rotated, and the image displayed on the monitor can always be made normal.
