Abstract

PROBLEM TO BE SOLVED: To provide a camera with a built-in stroboscope capable of preventing an electric shock accident caused by the high voltage of a main capacitor by preventing a photographer from touching terminals with his or her fingers. SOLUTION: The main capacitor 35 is incorporated in a main capacitor chamber 22, to be vertically long, in such a manner that the terminals 35a and 35b face down. In the bottom part, of the main capacitor chamber 22, a rib 42 for supporting the bottom surface of the main capacitor 35, to position it in a height direction is provided. Since the terminals 35a and 35b are covered with the rib 42 from the side surface side of a camera body 2, when the photographer grasps the side surface of the camera body 2, he or she never touches the terminals 35a and 35b with his or her fingers from the side surface side of the camera body 2. An opening 44 is formed in the rib 42. An electric discharge pin 45 is inserted into the rib 42 through the opening 44, to come into contact with the terminal 35a and an electric discharge pin 46 comes into contact with the terminal 35b through a notch 43. Thus, all the electric charges of the charged main capacitor 35 can be discharged.

d and 30e are engaged and locked.

In the main condenser chamber 22, a column-shaped main condenser 35 is vertically installed with terminals 35a and 35b facing down. In the main capacitor 35, the boosting circuit of the strobe device operates to boost the low voltage of the dry battery 29 to a high voltage, for example, about 300V, and charge the high voltage.

A strobe light is emitted from the strobe light emitting unit 10.

As shown in FIG. 1, the main condenser chamber 2
A rib 42 is formed integrally with the cover member 41 provided at the bottom of the second member. The rib 42 is used for the main condenser 3
5, the main condenser 35 is positioned in the direction of the center axis thereof, and covers the terminals 35a, 35b from the side of the camera body 2. The terminal 3 is provided on the rib 42.
An opening 44 is formed near 5a. This opening 4
Reference numeral 4 denotes one into which one of the pair of discharge pins 45, 46 of the discharge unit is inserted before repair or adjustment work. The opening 44 is formed with a diameter suitable for inserting the discharge pin 45, so that a worker's finger does not touch the terminal 35a.

In the discharge unit, the discharge pins 45 and 46 are connected via a discharge resistor (not shown), and the main capacitor 35 is charged by connecting the discharge pins 45 and 46 to the terminals 35a and 35b. It discharges all electric charges. The tips of the discharge pins 45 and 46 are brought into contact with the terminals 35a and 35b for connection.

When the front case 3 is removed from the camera body 2 for repairing or adjusting the camera with a built-in strobe, the main condenser 35 appears on the outer surface of the camera body 2. However, since the terminals 35a and 35b are covered by the ribs 42 from the side surface of the camera body 2, even if the operator carelessly grasps the side surface of the camera body 2, the terminal 3
Do not touch 5a, 35b. Therefore, an electric shock accident due to a finger touching the terminals 35a and 35b of the main capacitor 35 can be prevented.

Since the terminal 35a is arranged near the notch 43, it is relatively easy to touch. However, the terminal 35b is a negative electrode on the low voltage side, and the terminal 35a is
May be set as the positive pole on the high voltage side to prevent the electric shock accident more reliably.

In discharging the main capacitor 35, a discharge pin 45 is inserted into the inside of the rib 42 from the side of the camera body 2 through the opening 44, and the discharge pin 45 and the terminal 3
5a, the discharge pin 46 is inserted into the inside of the rib 42 from the front side of the camera body 2 via the notch 43, and the discharge pin 46 and the terminal 35b are brought into contact. As a result, both terminals 35 of the main capacitor 35
The discharge resistors a and 35b are connected, and all the electric charges charged in the main capacitor 35 are discharged via the discharge resistors. Therefore, the main capacitor 3
5 can prevent an electric shock accident due to the electric charge charged in the battery.
