2. Description of the Related Art A video camera device is designed to be small and lightweight, and is used not only for general consumer use but also for various fields such as security monitoring or installed in a production line for quality control of products. There is. The video camera device is provided with a large number of wiring boards, and these wiring boards are housed in the housing in a state of being stacked in multiple layers on studs formed integrally with the housing. In the video camera device, each stud is formed so as to have a different height corresponding to the stacking position of the wiring board, and a through hole for penetrating the stud for the upper layer is formed in the lower wiring board. Inter-board wiring is performed on each wiring board via, for example, a flexible cable attached afterwards.

In the above-mentioned conventional video camera device, since a large number of studs having different heights are integrally formed, the structure of the casing becomes extremely complicated and expensive. Further, in the video camera device, since the through hole of the stud is formed, the mounting density of the wiring board is reduced, which makes it difficult to achieve miniaturization, and the weight of the housing is increased.

Further, in the video camera device, since the wiring boards are sequentially fixed on the studs with screws or the like, the screwing work is increased and the workability of the electrical adjustment operation between the wiring boards is poor. was there. In the video camera device, for example, when a defect of the lower wiring board is detected in an operation test after assembling, the upper wiring board must be removed and adjustment operation or the like must be performed before reassembly. There was a problem such as poor workability. Furthermore, in the video camera device, there is a problem that the cost is increased as a whole by using a large number of relatively expensive flexible cables.

By mounting 111a to 113a, the effective mounting area is reduced and a predetermined mounting component cannot be mounted. Therefore, in the video camera device 100, the substrates 111 to 113 are increased in size or the number of substrates is increased, and the size is reduced.
There was a limit to weight reduction.

Further, in the video camera device 100, since the distance between the boards 111 to 113 is defined by the mounting distance of the board connector 108, the size of the base board 107 becomes large and the large dead space between the boards 111 to 113. Space will be created. Therefore, the video camera device 100 has a limit in miniaturization.

Further, in the video camera device 100, a plurality of board connectors 108 are mounted on the base board 107, and the board connectors 1 are mounted on the boards 111 to 113.
Since 11a to 113a are mounted respectively, the number of mounting steps increases. In addition, the video camera device 100
Are multiple board connectors and flexible cables 1
However, the number of parts is increased by including No. 09, and there is a problem that the cost is increased with an increase in the mounting process.

Furthermore, in the video camera apparatus 100, the positional displacement of the board connector 108 with respect to the base substrate 107, the positional displacement of the board connectors 111a to 113a with respect to the respective substrates 111 to 113, or an assembly error between the base substrate 107 and the bottom panel 103. As a result, the top panel 104 and the holder member 114 are displaced from each other.
In the video camera device 100, these synergistically serve as a load on the soldering portions of the board connectors 108, 111a to 113a. In the video camera device 100, there is a problem that this may cause a crack in the solder portion of each board connector and a connection failure.

The upper edges of the intermediate substrate parts 52 and 53 are positioned and held without being fixed. Therefore, the elastic holding member 90 reduces the number of steps by eliminating the need for the bonding step and eliminates the inconvenience caused by the outflow of the adhesive. The elastic holding member 90 simplifies the structure of the top panel 4 by eliminating the need to form a positioning portion on the top panel 4. The elastic holding member 90 improves the anti-vibration characteristics by reliably flipping the preprocessor board portion 52 and the signal generator board portion 53 even when vibration or the like is applied to the video camera device 1.

This can be dealt with by changing the proper positioning member 27. Since the video camera device 1 reliably positions and holds the multilayer flexible substrate 50 between the front panel 2 and the rear panel 3 by the positioning member 27 and the elastic holding member 90, a large vibration or the like is applied by the moving operation. It is also suitable for use in semiconductor manufacturing equipment and automatic inserters.
