Abstract

PURPOSE:To prevent a camera from mulfunctions at the time of continuous photographing using a flashing device by providing the camera with a release inhibiting means to be actuated by the existence of a detection signal generated during the period from the end of release to winding or a charging uncompletion signal for the flashing device. CONSTITUTION:A winding switch SW3 keeps the 2nd status during the period from the end of release to the completion of the next winding and turns on a transistor (TR) Tr3 at its ON status. Consequently TRs Tr2, Tr1 are turned off and a releasing electromagnet Mg1 is non-energized, so that shutter release is not carried out even if a release switch SW2 is turned on. During the period a charging uncompletion signal for a flashing device is supplied from a terminal 54, the TR Tr3 is turned on and the shutter release is also impossible even if the switch SW3 is turned off.

Description

[Detailed description of the invention] This relates to a camera with a built-in device.

Conventionally, camera flash devices, with the exception of special flash devices such as those that use a commercial power source or those that use a laminated battery, have short cycle times due to the fact that their power source must be miniaturized due to their form. (The time from when light is emitted until charging is completed) is relatively long, and if the power source battery deteriorates in 49 days, it will be significantly longer. Therefore, when shooting continuously using a flash device, the IJ? There was the hassle of waiting for cycle time and confirming that the flash device was fully charged before releasing the shutter. Furthermore, if an electric drive device for film winding and a flash device are used together and continuous shooting is performed, the film winding time of the electric drive device is so fast that the recycling time of the flash device cannot keep up with the speed of the flash device. The drawback was that some photos were taken with the light emitting light and some photos were not, resulting in random exposure even during continuous shooting.

When an electric drive device and a flash device are used together.k.

An invention has already been proposed in which the shutter release is performed after film winding by an electric drive device and charging of a flash device is completed, but this is not useful when winding the film manually.

An object of the present invention is to solve the above-mentioned problems, and to provide a system in which, when using a flash device, the shutter release is not activated until the flash device receives no charge incomplete signal input after film winding, regardless of electric or manual film winding. is to provide a camera that can be prohibited.

In order to achieve this object, the present invention enters the first state when the shutter release ends, and enters the second state when the film winding is completed.
a terminal for outputting the first state and the second state of the detection means as an operation command signal and a stop command signal to the electric drive device, and a terminal for inputting a charging incomplete signal of the flash device. A fourth feature is that the release thread raising means for inhibiting shutter release is configured to be operated by either the first state of the detection means or the input of a charging incomplete signal of the flash device.

The operation of one embodiment of the present invention configured as described above will be explained. First, a case will be described in which photographing is performed only with the camera 1 without attaching the electric drive device 101 and the flash device 201.

A will be explained with reference to the circuit diagrams of the camera 1 shown in FIG. 1 and the camera 10 shown in FIG. Now, when the camera l is in the completed winding state m (the state shown in Figure 1), the claw part 6a of the winding stopper lever 6 falls into the notch part 5C of the cam disk 5b, and the winding switch S
W3 is turned off. First, turn on the power switch SW5. When you press release switch 2, its is1
Since the contact pieces 31 and 3b are short-circuited during the stroke, the side light switch SWl is turned on. Then, in FIG. 2, the photometric circuit 21 becomes energized, so the photometric circuit 21 performs photometry and display. When the release button 2 is further pressed, the contact pieces 3b and 3C are short-circuited during the second stroke.
Release switch SW2 is turned on. Then, in FIG. 2, the base current of the transistor Tr20 flows as follows: resistor R3 → diode D3 → release switch SW2 → arc.
Transistor Tr2 is turned on. (Since this blackout curtain raising switch SWa is off, the base current of transistor Tr3 is also cut off and it is off.) Transistor Tr2
When turned on, the transistor Tri is also turned on, so that the charge of the release electromagnet Mg1K capacitor C1 flows and is magnetized by MI, and the shutter is released. [When the exposure is completed and the shutter rear curtain moves, the shutter rear curtain moves the winding stop lever 6 in the direction of the hour hand KM, and the claw s6
1 is removed from the notch @5C of the cam disc 5h, and the winding switch SW3 is turned on. 4I up switch SW3
When turned on, the base current of the transistor Tr3 flows through the resistor R5, the diode D4, the winding switch SW3, and the ground, turning on the transistor 'I'r3. Then, the emitter and pace of the transistor Tr2 are short-circuited and the transistor Tr2 is turned off, and the base current of the transistor Tr14 is cut off and turned off, and the release electromagnet MJ11 is also de-energized. When winding is performed and the winding shaft 5 rotates once and one winding is completed, the notch 5C of the cam disk 5b is placed in a position opposite to the pawl 6a of the winding stop lever 6, so the winding stop lever 6 is reversed. Rotates clockwise, and the pawl s6a engages the cam disk 5.
The notch wA5 of b engages again with c (at this time, the shutter trailing curtain is already charged, so the wind stopper lever 6
can be rotated counterclockwise) and the lift switch SW
3 is turned off (state shown in the first figure).

Since the winding switch SW3 is off from the end of exposure until the completion of the next winding, the release electromagnet Mg1 is not excited even if the release button 2 is pressed and the release switch SW2 is turned on. For this flash device:/
=-3 or when attaching a flash device to the synchro terminal 9 and performing flash photography, release the shutter,
When the front curtain of the shutter moves, the X contact SW4 is turned on, and the signal is transmitted to the flash device via the first contact 8a or the synchro terminal 9, and the flash device emits light.

In addition, if the flash device installed in the flash device seat 8 is of the type described above that can transmit the designated aperture of the flash device to the camera INK, the signal is transmitted via the second contact 8b, and the aperture is The control circuit 22 controls the aperture of the photographing lens to a specified aperture.

Next, a case will be described in which the camera IK electric drive device 101 is attached and a photograph is taken. First, electric drive device 101
To attach the camera L to the camera L, insert the positioning pin 114 into the positioning hole 11, rotate the knob 113a of the mounting screw 113, align the mounting screw 113 with the female tripod screw 10, and fix it. Then, the camera connection side terminals 153, 152, 151 .
154, 156 and 155 are respectively disposed on the accessory mounting surface 50 of the camera 1 at positions facing the terminals 53, 52, 51°54, 56 and 55.
．． 52, 15251 and 151, 54 and 154, and 55 and 155 are electrically connected, respectively. Then, the electric drive wheel [
101 photometering switch SW 101 is terminal 51 and 151
and the photometry switch SW of camera 1 via 52 and 152.
The release switch SW l02 of the electric drive unit [1101 is connected in parallel with
Connected in parallel with 2. Therefore, the release button 2 of the camera 1 and the release button 102 of the electric drive device 101 can perform exactly the same operation. Here, in order to simplify the explanation, a case will be described in which the release button 102 of the electric drive device 101 is used. It is now assumed that the camera 1 is in the winding condition II (the state shown in FIG. 111), and the selector switch 5W107 of the electric drive unit fi101 is switched to the C side (continuous shooting). First, the power switch SW5 of the camera l and the power switch 5W105 of the electric dX motion device 101 are turned on. In this state, the electric drive device 1i1
01 circuit is winding switch SW3 and changeover switch 5
Since W107 is off, transistor Tr103 is on, so transistor Tr102 is on, transistor 'l'r101+t sonoemitter Φ base is shorted, so it is off, relay coil L is not excited, and therefore switch 8W10G is on the NC side. Both ends of the motor M are short-circuited, and the motor M is in an inoperative state. Then, when the release button 102 of the electric drive device 101 is pressed, the photometry switch 5WIOI is turned on at the second stroke, and the photometry display is performed as described above.When the IJ-Z button 102 is then further pressed, the release switch 5WIOI is turned on at the second stroke. 8W102 is turned on, the camera 1 releases the shutter as described above, and when the shutter trailing curtain runs, the winding switch SW3 is turned on. Then, the transistor Tr is connected via the terminals 54 and 154.
Since the pace of J03 is shorted to ground, transistor Tr103 is turned off, and transistor 'rrioz is also turned off.

(Since the selector switch 3W107 has been switched to CIII, the pace current is cut off by turning off the transistor Tr 103.) Then, the transistor Tr
101 is turned on, the relay coil L is excited, and the switch 5W106 is switched to N0ilK, so that the motor M is energized and starts winding the film. When the winding is completed, the winding switch SW3 is turned off, as described above.
Transistor 'rrtoa turns on, transistor Tr
102 is also turned on, the transistor T ``101 i! 1ktH1 is connected between the emitter and the base, and it is turned off, the relay coil L is de-energized, and the switch 5W106 is switched from the NC side to NC91l, and both ends of the motor M are turned off. Short circuit and apply the brake to bring it to a sudden stop.Also, if you keep pressing the release button 102 at this time, as shown in Fig. 2, when the winding switch SW3 is turned off,
y jitter r3 turns off and transistor ']['
r2 is the emitter. The short circuit between the paces is released, and the pace current flows from resistor R3 to diode D3 to terminal 5.
3 → terminal 153 → release switch 5W102 → ground and turns on.

Since the transistor Tr1 is turned on, the release electromagnet Mfl is excited again to perform the next shutter release. When the selector switch 5W107 of the electric drive device 101 is switched to S@ (-frame shooting mode), even if the shutter release is completed and the 1st winding switch SW3 is turned on, the release button 102 is pressed and the latch is on the side. Since the optical switch 8W 101 is on, the transistor Tr1020
Base current is resistor R102 → changeover switch 5W107 →
The flow goes from photometry switch 5WIOI to ground, transistor Tr 102 continues to be on, and when the release button 102 is released and photometry switch 5WIOI is turned off, transistor Tr 102 is turned off and transistor Tr102 is turned off.
O1 is turned on, relay coil L is excited, and winding starts, resulting in one-frame photography.

Next, the camera IK (K without the electric drive device 101 installed)
) The case where photographing is performed with the flash device 201 attached will be explained. First, to attach the flash device 201 to the camera IK,
While inserting the positioning bin 214 into the positioning hole 11, turn the knob tliB213a of the mounting screw 213 to screw the mounting screw 213 into the female tripod screw lO and fix it.

Then, the 25Ω terminals 253, 252, 25 on the top of the flash device
1.254.256 and 255 are terminals 53.52.51.54.56 and 5 of the accessory mounting surface 50 of camera l, respectively.
Since the terminals 53 and 2 are located opposite to each other,
53.52 and 252.51 and 251.54 and 254.5
6 and 256 and 55 and 255 are electrically connected, respectively. Then, the photometry switch 5W201 of the flash device 201 connects terminals 51 and 251 and 52 and 252.

The release switch 5W202 of the flash device 201 is connected in parallel with the release switch SWg of the camera 1 via terminals 52 and 252 and 53 and 253. Shikatsu [Even if you press the release button 2 of the camera 1, the flash device 201's L/
Exactly the same operation can be performed using the IJ-X button 202.

Here, in order to simplify the explanation, a case will be described in which the release button 202 of the KRL3 party device 201 is used. Assume that the camera 1 is now in a fully wound state (state II in FIG. 1), and the shutter speed is set to the synchronized shutter speed (for example, /go).

First, the power switch SW5 and the power switch swzos of the flash device 201 are turned on. Then, in FIG. 4, since the main capacitor C201 is in a discharged state, the neon tube N
is not lit.

Therefore, phototransistor P is off and transistor Tr 203 is also off. As a result, the transistor Tr 202 is turned on, and the transistor Tr 202 is turned on.
201 is also turned on and does X. Therefore, in Figure 2 and Figure 4 ~1, the base current of transistor Tr3 flows through resistor R5 → diode D4 → terminal 54 → terminal 2, regardless of whether winding switch SW3 is off.
54 -> diode L) 202 -> diode D203 -> transistor Tr201 -> ground, so the transistor Tr3 turns on and prevents the transistor Tr'20 from turning on. In this state, even if the release button 202 is pressed and the release switch 5W202 is turned on, the release electromagnet Mgl is not excited and the shutter cannot be released. The power switch 5W205 of the flash device 201 is turned on, and the main capacitor C201 is charged with the voltage boosted by the booster circuit 221. When the main capacitor C201 is charged to a predetermined voltage, the neon tube N is lit. Then neon tube N
Upon receiving the light, the phototransistor P turns on, and the transistor Tr203 turns on. Then, the emitter and base of the transistor Tr 202 are short-circuited, so that the transistor Tr 202 is turned off, and the transistor Tr 201 is also turned off. Then, the pace current is cut off from the transistor Tr 3 in the camera 1, turning it off, and the camera 1 becomes ready for release.

The flash device 2010 light emission control circuit 222 indicates that the specified aperture value set in the flash device 201 is the terminal 256 and 561.
The aperture control circuit 22 controls the aperture value of the photographing lens to the specified aperture value using known means. In this state, when the flash device 1201 is turned on at 17-xypyzo2kW, the dimmer switch 8W201 is turned on at the first stroke, and the photometry and measurement are performed as described above.
When the release button 202 is further pressed, the release switch 8W202 is released with the #I2 stroke.

4 is turned on, and the trigger capacitor C202 in the flash device 201 is connected to the ground Kff via the terminals 5s and 255.
1 is connected, the flash discharge tube Xe emits light from the trigger coil TK, and when the predetermined amount of light emission is completed, the light emission control circuit 222
．． The light emission is stopped. Flash discharge tube) (When e emits light, the charge in the main capacitor C201 is discharged, so its potential decreases and the neon tube N goes out.Then, the phototransistor P is turned off, and the transistor Tr203
is also turned off. Then, charging of the capacitor C203 is started, and after a predetermined time determined by the capacitor C203 and the resistor R204, the transistor Tr202 is turned on, the transistor Tr201 is also turned on, and the transistor E''r3 of the camera 1 is turned on again. time is x
It is preferable to make the time longer than the time from when the contact SW4 is turned on until the end of exposure at the synchronized shutter speed (approximately 9). ) When the camera l finishes the exposure at the synchronized shutter speed and the shutter trailing curtain runs, the winding switch SW3 is turned on as described above.Then, the film, etc. is wound by the unillustrated winding lever, and the flash I & 20
Once the next charging is completed, you can take the next picture.

Next, a case will be described in which the camera IK electric drive device 1101Q is attached and a flash device 201 is further attached to the bottom surface 160 of the camera to take pictures. To further attach the flash device 201 to the electric drive device 101 attached to the camera 1 as described above, while inserting the positioning pin 214 of the flash device 201 into the positioning hole 111 on the bottom surface 160, insert the screw 213 of the flash device 201. Rotate the knob portion 213m to fit and fix the female tripod screw 110tC on the JiE surface 160.

Then, the terminals 253 and 25 on the top surface 250 of the flash device 201

Even with the release button 2 of camera 1, the electric drive [position 101]
Both the release button 102 and the release button 2d2 of the flash device 201 can perform the same operations. Here, to simplify the explanation, a case will be described in which the release button 202 of the flash device 201 is used. Assume that the camera l is now fully wound (the state shown in FIG. 1), and the shutter speed is set to a synchronized shutter speed (for example, -8) K. Changeover switch 5W10 of electric drive device 101
7 is set to C@ (continuous shooting). First, power switch SW5 of camera l, electric drive device 10
1 power switch 5W105. And turn on the power switch 5W205 of the flash device 201. Then, as described above, the flash device 201 uses the transistor Tr 2 until the main capacitor C 201 reaches a predetermined charging voltage.
01 is turned on, terminals 254, 164 and 154
and 54, the transistor Tr3 of the camera l is turned on to prohibit the shutter release. At this time, terminal 164
is also connected to the base of the transistor Tr103 in the electric drive device 101, but the diodes D202 and D
Since the voltage drop across 203 keeps it at about 1.4V, transistor 7r 103 is not turned off and motor M is not turned on. Next, the main capacitor 02 of the flash device 201
When 01 reaches a predetermined voltage, the transistor T
r20 l b'-off, and the prohibition of shutter release is canceled. When the release button 202 of the flash device 201 is pressed in this state, the photometry switch 8W201 is turned on with the first stroke, metering and displaying the light as described above, and then when the release button 202 is pressed again, the release is released with the second stroke. Switch 8W202 is turned on,
As described above, the camera l releases the shutter, the flash device 201 emits light, and the exposure is completed. Then, as described above, the winding switch SW3 is turned on, and the electric drive device 1 is turned on.
01 ti As described above, the motor M is energized to wind up the film, etc. While charging the flash capacitor C201, as described above (after a predetermined time, the transistor Tr20
Turn on 1 to prohibit shutter release of camera 1. When the winding of the film, etc. by the motor MK in the electric drive device 101 is completed, the pawl portion 6 of the winding stop lever described above is immediately activated.
a engages with the notch 5C of the cam disc 5b, turning off the winding switch SW3 and cutting off the power to the motor M. If the charge of the main capacitor C201 in the flash device 201 reaches a predetermined voltage at this moment, the neon tube N lights up and the transistor Tr201 is off as described above.
If the release button 202 is held down when the winding is completed, when the winding is completed and the winding switch SW3 is turned off, the transistor Tr3 is turned off, and as described above, the transistor 1+ r t is turned on and the release electromagnet Mgl is excited. Then do the next shutter release. When the winding is completed and the winding switch SW3 is turned off, if the charge of the main capacitor C201 in the flash device [201] has not yet reached the predetermined voltage, the neon tube N will not light up.
Since phototransistor D also remains off, transistor D1201 remains off, and terminal 25
4 is conductive to earth at a potential of about 1.4 V. However, in camera I, transistor Tr3
The base current of resistor R5 → diode D4-4 terminal 54
→Terminal 154→Terminal 164→Terminal 254-e Taioh)
"L) 202-*/Iode L) 203 → Transistor Tr 201 → Flows to ground, transistor Tr 3 remains on, and the shutter release remains prohibited. On the other hand, in the electric drive device 101, the transistor Tr 103 The base is connected to terminal 164 → terminal 254 → diode D202 → diode D203-e) transistor 'l'r201-e, but terminal 16
4 (that is, the terminal 254) Since the o potential is approximately 1.4 V, the transistor Tr103 is turned on by the winding switch SW3.
When it turns off, it turns on and motor M turns on as described in 1wt1.
At the same time, both ends of the motor K and M are short-circuited to bring the motor to a sudden stop. As a result, the camera lK11EI [recommended device 1]
01 and the flash device 201 for continuous shooting, the winding of the film, etc. is completed, and the flash device 20
The next shutter release is performed when the first charge reaches a predetermined voltage.

In the illustrated embodiment, transistors Tr3. Resistor R4,
R5 and the diode D4 correspond to the release inhibiting means of the present invention, the winding switch SW3 corresponds to the detecting means of the present invention, and its on state corresponds to the first state sK, and its off state corresponds to the iE2 state. Further, the terminal 54 corresponds to both the terminal for outputting the state of the detection means of the fIA&c# of the present invention and the terminal for inputting the charging incomplete signal of the flash device.

According to the illustrated embodiment, when using the flash device, the camera shutter release 1l-Jjl can be stopped until charging is completed, whether it is electric winding or manual winding.

In addition, a charging incomplete signal from the flash device 201 (the diodes 0202 and 20 due to the transistor 'rrzoi being turned on)
3 (a signal with a voltage drop of about 1.4 V) is input, and the ON and OFF states of the release switch 8W3 are input to the operation command signal (earth potential signal) and stop command signal (earth insulation signal) to the electric drive device 101. ) are shared by one terminal 54, so the number of terminals of the camera l can be reduced. Note that the charging incomplete signal from the flash device 201 and the operation command signal to the electric drive device 101 are a signal of 1.4■ and a signal at ground potential, and since there is a potential difference, the charging incomplete signal is sent to the electric drive device. 101 cannot be made by mistake.

In the illustrated embodiment, one terminal 54 is used as a terminal for inputting a charging incomplete signal and a terminal for outputting a command signal to the electric drive device 101, but the present invention is not limited to this. , separate terminals may be used.

Further, the present invention is not limited to a type of camera having an externally attached flash device, but can be applied to a type of camera having a built-in flash device.

As explained above, according to one aspect of the present invention, the period from the end of the shutter release to the film winding is detected by the detection means, regardless of electric winding or manual winding, and the %IEI
Since the release prohibition means is configured to be operated by either the first state of the detection means or the manual charging signal of the flash device, when the flash device is used, the release prohibition means is activated after the film is wound. Therefore, the shutter release can be prohibited until the charging incomplete signal is no longer input. In addition, since terminals are provided to output the positive and negative states of the detection means as operation command signals and stop command signals to the electric drive device, whether the film is wound electrically or manually, the main Invention can be applied.
