Since this light emission trigger control circuit includes a high voltage circuit, it is often arranged near the strobe light emitting device in consideration of the influence on the camera operation control circuit and the like. In this case, since the booster circuit and the light emission trigger control circuit are usually provided on the same board, a relatively large board equipped with the booster circuit together with the light emission trigger control circuit should be provided near the strobe light emitter. Due to the large shapes of both the power supply battery and the capacitor, the power supply battery and the capacitor were arranged apart from each other.

Therefore, the storage space of the camera body is not effectively used, and the booster circuit is arranged away from the capacitor and the wiring thereof is long, so that the electric resistance is large and the charging time of the capacitor is long. There was a problem such as becoming.

[Example of device]

 The present invention will be described below with reference to illustrated embodiments. FIG. 1 is a schematic view showing a state in which a camera body 12 of a camera with a built-in strobe 11 to which the present invention is applied is viewed from the front. The camera body 12 has a taking lens 13 in the center and storages 16a and 16b on the left and right. The strobe light emitting device 15 is arranged above the right housing portion 16b, and a light emission trigger control circuit is provided behind the strobe light emitting device 15 and has a light emission trigger control circuit for controlling the light emission of the strobe light emitting device 15 by the condenser 17. 21 are arranged.

A booster circuit board 20 provided with a booster circuit for boosting the voltage of the power supply battery 19 and storing it in the capacitor 17 is arranged above the left storage portion 16 a, and below this booster circuit board 20. A capacitor 17 having a capacitor terminal directly coupled to 20 and a power supply battery 19 adjacent to the camera front side of the capacitor 17 are adjacent to each other in the front-back direction of the camera strobe built-in camera 11 (in the optical axis direction of the taking lens 13). It is arranged. As a result, the booster circuit board 20 and the power supply battery 19 are arranged very close to each other, and the +/- both terminals 19a and 19b of the power supply battery 19 and the booster circuit board 20 are compared to the conventional one. Are connected by extremely short lead wires 25. In addition, at the tip of each of the two lead wires 25, there are provided electrode portions 22 and 23 for contacting the positive and negative terminals 19a and 19b of the power supply battery 19 to electrically connect the power supply battery 19 to the booster circuit board 20 side. Have

A camera operation control board 18 for controlling various camera operations is arranged in the middle of the left and right storage parts 16 a, 16 b, that is, in the center of the upper part of the camera body 12. On the camera operation control board 18, the other end of the lead wire 26 whose one end is connected to the booster circuit board 20 and the other end of the lead wire 27 whose one end is connected to the light emission trigger control board 21. Are connected to each other, and the booster circuit board 20 and the light emission trigger control board 21 are connected to each other by a lead wire 29.

In the present strobe camera 11 having the above-described configuration, the booster circuit and the light emission trigger control circuit are provided on different substrates, that is, the booster circuit substrate 20 and the light emission trigger control substrate 21, and the booster circuit substrate 20 and the capacitor are provided. Since the 17 and the power supply battery 19 are collectively arranged in the storage portion 16a on the left side of the taking lens 13, the storage space permitted by the camera body can be used extremely effectively. Moreover, since the capacitor 17 has its capacitor terminal directly connected to the booster circuit board 20 and the power supply battery 19 is disposed adjacent to the capacitor 17 and the lead wire 25 is extremely short, the booster circuit board 20 and the capacitor 17 are connected to each other. The distance on the wiring between 17 is saved, which reduces the electric resistance, and the charging time of the capacitor 17 is shortened as compared with the conventional case. As a result, smooth flash photography can be expected.

[Effect of the device]

 As described above, according to the present invention, the booster circuit that boosts the voltage of the power supply battery and stores it in the capacitor, and the light-emitting trigger control circuit that controls the light emission of the strobe light-emitter by this capacitor are provided on different boards, respectively. Since the board, capacitor, and power supply battery equipped with the booster circuit are arranged adjacent to each other in the camera body, the storage space allowed by the camera body can be used extremely effectively, and the booster circuit is further provided. Since the wiring between the substrate and the substrate equipped with the light emission trigger control circuit can be shortened to reduce the electrical resistance, the charging time of the capacitor can be shortened.
