The connector 237 attached to the extended portion of the capstan motor PCB257a is connected to the head amplifier PCB187 (FIGS. 1 and 3).

Further, the frame 1 made of resin such as plastic is provided with a pair of guide ribs 249a which are stud ribs (FIGS. 1 and 3), and the camera PCB 249 guided by the guide ribs 249a is a connector of the main PCB 240. 246 is inserted and combined. In the present invention, the boss 248, the engaging piece 187a, and the guide rib 249a are collectively referred to as a stand rib.

Further, the main PCB 240 (FIG. 2) is provided with a plurality of control switches 241, REC switches 242, light emitting diodes 243, light receiving sensors 244, and DEW sensors 245 so that a predetermined electric circuit is configured. Has become.

In order to assemble the head amplifier PCB 187, the camera PCB 249, and the main PCB 240 to the frame body 1 made of resin such as plastic, first, the frame body 1 is attached to the main PCB 240. Next, as shown in FIG. 4, a head amplifier PCB 187 is assembled with a video head connector 233, a cylinder motor connector 234, an erasing head connector 235, an ACE head connector 236, and a capstan motor connector 237, and a mode. The changeover switch 238 is attached, and the connector of the head-up PCB 187 is inserted into the connector 247 of the main PCB 240. Then, the head amplifier PCB 187 is engaged with the engaging pieces 187a that are stud ribs provided on both sides of the frame body 1 made of resin such as plastic, and the end of the earth brush assembly 181 is fixed to the head amplifier PCB 187 with the screw 186a. While being fixed, the capstan motor connector 237 is inserted, and the mode changeover switch 238 is locked to the motor holder (not shown) by the stepped screw 238a loosely fitted in the rotation center hole of the mode changeover switch 238. Let

Next, the connector of the camera PCB 249 is inserted into the connector 246 of the main PCB 240 along the guide rib 249a to complete the assembly. The chassis S to which the rotary head cylinder H is assembled may be integrally formed with the frame body 1 or may be a separate body. Further, although the main PCB 240 is fixed to the frame body 1 with the screw 248b in the present embodiment, it may be fixed with another coupling member such as a rivet. In addition, in this embodiment, the head amplifier PCB 187 is supported by the engagement piece 187a, and the camera PCB 249 is supported by the guide rib 249a. But it's okay. Further, although the present embodiment has been described as an example applied to a portable type video camera, it is needless to say that it can be widely applied to a video tape recorder, a video player, and other AV equipment.

[0014]

[Effect of device]

 As described in detail above, according to the present invention, it is easier to assemble than in the past and can be assembled easily, so that the number of assembling steps can be reduced, and further, since the number of parts is reduced, the parts cost is reduced. In addition, the number of parts is reduced, and the weight is reduced.
