Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bounce photography device which detects whether the light emitting part of a flash device is in the bounce position or not. The normal position is a state where the optical axis of the camera's photographing lens and the optical axis of the light emitting part of the flash device are divergent, and if flash photography is performed in this state, the flash f! The crab illuminates the subject t-directly. Further, the bounce position is a state in which the flash device indirectly illuminates the subject, and the light emitting section is displaced from the normal position. In this state, the flash device illuminates objects around the subject, such as walls, and the reflected light from the walls illuminates the subject.

Conventionally, the method for performing bounce photography is to make the light emitting part of the flash device attached to the camera body movable, and change the direction of the light emitting part upward, downward, left, and right to emit flash light. However, after performing such bounce photography, the user forgets to return the light emitting unit to its normal position and continues to take the next photo, resulting in a failure in photography.

Further, even if bounce photography is not performed, during normal use, the light emitting portion may be displaced to the t-bounce position by accidentally applying an impact or the like. When the light emitting part is displaced to the bounce position in this way, the change in the displacement angle is small, and from the outside it is often difficult to clearly see that the light emitting part is at the bounce position C. Therefore, there is a drawback that the next photographing is performed without noticing the displacement, resulting in failure of photographing for 1 second.

In order to eliminate such drawbacks, the present invention detects whether the light emitting part of the flash device is in the normal position or in the bounce position, and in each case C; occurs on the output, thereby causing both cases tl
The purpose is to differentiate by house.

FIG. 1 shows a first embodiment of the invention. A light emitting section 1 having a flash discharge tube is rotatable upward and horizontally with respect to a flash device main body 2, and FIG. 1 shows a state in which the light emitting section 1 is rotated upward.

The light emitting unit 1 can rotate 5 times in the left and right directions about the circular portion at the top of the rotary table 3 as an axis. Further, the rotary table 3 can be rotated upwardly by a shaft 6 with respect to the flash device main body 2C, so that the light emitting section 1 can be rotated in any combination of upward, left and right directions.

The main body 2 is attached to the camera body by a hot shoe 10. The spring material 8.9 constitutes a switch sw, t-,
This switch 8W (- indicates that there are eight light emitting parts 1, and the release bar 7 for detecting the sensor me is attached to the tip of the spring member 9, and in the illustrated state, the release bar 7 is released by the spring pressure of the spring member 9. Tip of 7 7
s protrudes from the opening in the upper wall surface of the main body 2, the spring members 8.9 are in contact, and the switch 8W is closed.

Grooves 4, 5. Central part 1 heat, stick 7. The switches SW constitute bounce position detection means.

This bounce position detecting means and the LID display element 13 constitute a light emitting part position detecting means.

The IID display element 13 is attached to the main body 2 or the like and is visible from the outside. The lower wall surface of the light emitting part 1 has a groove 4.5 into which the tip end 7 of the rod 7 is inserted.

The grooves 4.5 are each formed in the shape of a circular arc centered on the rotation center of the light emitting section 10, and the arc is formed by an angle that allows the light emitting section 1 to rotate left and right, respectively.

Next, the operation will be explained. When the light emitting part 1 is in the normal position, the tip of the rod 7 is connected to the light emitting part 10, grooves 4 and 1l.
Pushed downward by the central portion IIl between l15, the rod 7 pushes the spring member 9 downward and away from the spring member 8, the switch sw is turned off, and the LICD display element 13 is turned off. From this state, turn the light emitting part 1t to the left or right.
When the rod 7 is rotated to the bounce position, the tip 7a of the rod 7 falls into the groove 4 or 5, the spring member 8.9 comes into contact, the switch sw1 is turned on, and the LED display element 13 lights up.

Also, when the light emitting part 1 is rotated upward, the pressing by the center part C- of the tip part 7 is released, so the spring material 8°9 comes into contact, the switch $Wl is turned on, and the nozzle head displays 1cD. Element 13 lights up.

Because of this structure, in this embodiment, if the light emitting part 1 is rotated and forgotten to return to its normal position, or if the light emitting part 1 is displaced from its normal position due to an impact or the like, the IID display element 13 It lights up to alert you and prevent shooting failures.

The 211th is the second fruit 11APl of the present invention! show. This circuit is provided in an electronic flash device that is capable of automatically controlling light emission and manual light emission. Terminals ``■'' and ``b'' are connected to the spring material 8.9 shown in FIG. 1**.

LID display elements 25 and 26 are attached to the outer wall of the electronic flash device, and indicate which mode is currently selected by switching a switch 270 that moves to switch between automatic dimming light emission and manual light emission. Resistance 14, 15.1G, 20.2

The tLg DlN indicator 11 constitutes a flip-flop circuit for blinking, and the transistor 18 is connected to the output of the flip-flop circuit. The current flowing through the LHD display element 25 or 26 is controlled.

To explain the operation of this circuit, as shown in Fig. 1, when the light emitting part 1 is in the normal position, the spring material 8°9 is not touched, so there is no oscillation in the 7 flip-flop area, and the transistor 23 is in the ON state. Therefore, the transistor 18 is turned on. In this case, if switching is selected as shown in the second diagram, the IJD display element 25 indicates manual light emission mode.
Light up. Further, when the switch 27 selects the automatic light control mode, the LED display element 26 lights up. Next, light emitting part 1
When the switch SW1 is in the bounce position, that is, rotated upward or in the left-right direction, the switch SWl made of the spring material 8.9 is closed, the circuit of the knob 70 oscillates, and the output turns on the transistor 18.

0FFt-Repeat. In this case, if the switch 27 is selected as shown in the second diagram, the IID display element 25 will blink, warning that the light emitting unit 1 is in the bounce position.

% is the same when the switch 27 selects the automatic light control mode. In this way, in this embodiment, automatic dimming light emission,
The manual light emission mode display IID'l, which also serves as the display element for the bounce operation supervision means, eliminates the need for a dedicated LID, and can be used to provide a high level of warning by blinking.

When the switch SW1 is opened, a current flows through the switch 9 to cause the display element 291 to light up.

The main capacitor 35 is charged by a known booster circuit 36C and connected in parallel with the flash discharge tube 34. Resistance 32.
33. The neon tube 31 constitutes a charging voltage detection circuit, and when the main capacitor 35 exceeds a certain voltage, the transistor 30t is turned on.

The device of this embodiment [when operated, when the switch 8W made of spring material 8°9 is OFF, that is, when the light emitting part 1 is in the normal position, the capacitor 35 is fully charged and the LI is turned off.
The D display element 29 lights up. When the switch sW is in the bounce position and the switch sW is ON, the LID display plate 2e flashes when the capacitor 35 is completely charged.

In this way, in this embodiment, a dedicated LID is not required since it is used both as the charging completion display element 29 and the display element of the light emitting part position detection means.

No. 411 shows the fourth embodiment of the present invention, this example 11/A
f! In 4, the bounce position is displayed with a sound.

The display element consisting of the piezoelectric buzzer 38 is connected to the sound generation circuit 37, and the input terminal -1b of the sound generation circuit 370 is connected to the switch SW1 in FIG.

When the light emitting unit 1 in the first E is in the normal position, that is, when the switch 8W1 is 0 DEFO, the sound generation 111137 does not operate. When the light emitting unit 1 rotates upward and horizontally and is in the bounce position, the switch 8W is turned on and the sounding circuit 37 drives the piezoelectric buzzer 38 to issue a warning.

In this way, in this embodiment, since the warning is audible, there is no need to watch the display element that displays the bounce position shadow. However, the display element is not limited to a piezoelectric buzzer, and the warning sound is not limited to a continuous sound, but may be an intermittent sound, a voice, etc.

It is also possible to use both a sound display element and a light display element.

FIG. 5 shows a fifth embodiment of the invention. Flash discharge tube 34
The light emitting unit 1 included in the main body 2C is rotatable in vertical and horizontal directions, and its rotation mechanism is the same as that shown in FIG. 1, but in this embodiment, downward rotation is added. The reed switch 41 constitutes a left-right displacement detection means.

This switch 41 is turned OFF because the magnet 40 is close when the light emitting portion 1 is at the normal position C shown in the figure. When the light emitting unit 1 rotates to the left or right and reaches the bounce position, the reed switch 41 is turned on because the magnet 40 moves away. The reed switch 43 constitutes vertical displacement detection means. When the light emitting part 1 is in the bounce position where the light emitting part 1 is rotated upward or downward, the magnet 42 moves away.When the light emitting part 1 is in the normal position, the switch 43 is turned on. Since it is, it is turned off. Resistance 44.45.2 color LI
The D display element 46 and the power source E input the outputs of the switches 41 and 42, and constitute a circuit for displaying the bounce position.

The two-color 110 display element 46 is a display element that includes two-color light-emitting elements of horse mackerel in one case.

This display element is attached to the main body 2 or the like and is in a state where it can be observed from the outside. 0 Explanation of operation 0 Light emitting part 1 is in normal position 1; In a certain state, switch 41,
Both switches 43 are OFF, and both the two-color IID display elements are off. Light emitting part 1t - bounce position 6 rotated only in left and right direction; then switch 41 is turned on
L The two-color LID display element 4G emits red light. When the light-emitting part it is rotated only in the vertical direction to the bounce position, the vertical direction warning switch 43 is turned on and the two-color display element 4
6 emits green light. Also, ta11 in both left and right directions and up and down directions.
If it turns on, switches 41 and 43 are turned on and 2 colors II
Since the D display element 46 emits red and edge light, it appears to be orange from the outside.

Because of this structure, in this embodiment, in the bounce position, it is possible not only to issue a warning when the light emitting unit IoIt is rotated, but also to indicate the direction of rotation as a difference in the color of the light emitted. Furthermore, by using a two-color LED display element (46C), only one display element is required, which is advantageous in that the number of parts can be reduced and the configuration can be simplified. In this embodiment, two-color IJDt is used for the display element 46, but separate I and ID may also be used.

Furthermore, in this embodiment, there are two switches 4 in the left and right directions and in the up and down directions.
1.431, but it is also possible to specify the rotation direction t in more detail by providing separate switches for the left and right directions, or the upward and downward directions.

D allows more information to be displayed. In this embodiment, the display is displayed by changing the blinking frequency of the display element 57, but various applications such as using a sounding element and changing its oscillation frequency or using an intermittent tone and changing its intermittent frequency may be used instead. is possible.

In the above embodiments, a mechanical switch and a reed switch were used as the bounce position detection means, but various methods can be used, such as using a photoelectric conversion element to block the light source T by rotating the light emitting part 10 times, and detecting the bounce position from 22. I can think of it.

No. 81!3 shows the seventh embodiment of the present invention. In this embodiment, the flash device main body 2 can be attached to the camera main body B8. This camera body 58C; the light emitting unit 1 provided with the display element 59 of the bounce cost detection means is connected to the flash device 2 by a rotating shaft 6 2a so as to be rotatable in the vertical direction.
