Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a connector for a detachable unit type electronic camera.

(Prior Art) In place of conventional cameras that record subject images using silver halide film, electronic cameras convert subject images into electrical signals using an imaging means such as CCI (CCI) and record these electrical signals on magnetic disks. It has appeared in recent years.

According to this electronic camera, it is stationary! Not only can recording of image signals and reproduction of still image signals recorded on magnetic disks be performed in real time without the need for conventional silver halide film development processing, but also recording equipment such as video tape recorders can be used. By using K, it is also possible to record moving images. In an electronic camera that can be used in such five virtues, it is desirable to use only the parts that are necessary depending on the purpose of use, from the standpoint of miniaturization and operability. In order to meet such demands, the present applicant previously proposed a detachable unit type photographic device as described in Japanese Patent Application Laid-Open No. 182964/1983. This is composed of a main body of an electrophotographic apparatus, a unit that is detachably attached to the main body, and a means for electrically connecting this unit and the main body. It has a built-in recording and reproducing means for recording and reproducing image information. According to this method, since the electronic camera is formed into a unit, it can be made smaller and lighter depending on the purpose of use compared to an integrated camera. Considering the combinations depending on the purpose of use, this electronic camera can be divided into three units: an imaging section, a video monitor section, and a recording/playback section for one image. Various combinations of two or three of these units can be used. Since it can be used for various purposes, it is preferable to unitize it into at least three parts.

However, if an electronic camera is divided into units in this way, a connector must be provided for each unit to detachably connect the units, and conventionally, COD or NTSC encoders must be installed. Instead of sending synchronizing signals from one synchronizing signal generating circuit to multiple circuits driven by synchronizing signals, the multiple circuits that require synchronizing signals are divided into multiple units. In other words, when units that do not have a synchronization signal generation circuit are combined and used at °C, a synchronization signal for driving must be provided by some means,
For this purpose, yet another synchronization signal generation circuit is required. However, it is undesirable in terms of space and economy to incorporate the synchronizing signal generating circuits in each unit in this way.

A possible solution would be to install the synchronizing signal generation circuit externally to the unit as necessary to supply the synchronizing signal into the unit, instead of providing the synchronizing signal generating circuit inside the unit. Fortunately, when unitized, each unit is provided with a connector as described above. Therefore, it would be advantageous to make clever use of this connector K' to supply a synchronization signal into the unit.

(Objective) An object of the present invention is to configure an electronic camera with a plurality of units, and supply a synchronization signal to the electric circuit in each unit by using a connector for detachably connecting the units. To provide a connector for a removable unit type electronic camera.

(Summary) In order to achieve the above object, the present invention provides a synchronization signal generation circuit for sending a synchronization signal to the electric circuit in each unit in a connector for connecting a plurality of units.

However, in this case, it is necessary to use an optical vinyl finder 500 for monitoring the imaging screen.

First, the operation in case (1) above will be explained with reference to FIG. In this case, terminals a, -an of connector CN IA.

Each of b to f is electrically connected via a relay connector 700, and similarly terminal a of connector CNs.

~an, e, respectively; terminals a, ~ of connector CN5m
Each of an and e is electrically connected via a relay connector 700. Furthermore, connector CN2 terminal a1
- Each of an and b-f is connected to each terminal a, .

A synchronization signal generation circuit 604 of the relay connector 600 is connected to each of terminals a and -an of the CN 211. In this way, each connector is connected, and each
The units 100, 200, 300 and the grip portion 400 are mechanically coupled. Then, when power (not shown) is supplied to each part, two 100, 200, 300K synchronization signal lines S, 100, 200, 300 K are connected to terminals a, -an of the relay connector 600. . .

Various synchronization signals are supplied via S and S.

Now, when the recording mode is set using a switch (not shown), the output of the mode switching circuit 9 becomes H level, and each switch circuit 16, 50, 51, 52 is activated, and each switch circuit 16, 50, 51, . 52 is the common end and normally off #! as shown by the dashed line. becomes conductive.

In this state, since the shutter 3 is in an open state, a subject image is formed by the photographic lens 1 on the four C0D light receiving surfaces. At this time, the intensity of light incident on the CCD 4 is changed by the iris 2. The image formed on the CCD 4 is two-dimensionally scanned by a horizontal scanning drive signal and a vertical scanning drive signal from the synchronization signal generation circuit 604.
An electrical signal corresponding to the subject image is generated at the output of the CD 4. After this signal is amplified to a predetermined level by a preamplifier 1 path 6 IC, the signal processing circuit 7 outputs the synchronization signal line S from the synchronization signal generation circuit 604. . Signal Y, signal, (RY) based on the synchronization signal of.

A (B-Y)□ signal is created.

These three types of signals, namely, Y1 signal, (RY)1 signal, and (B-y)1 signal are connected to connector CN1, CN I
It is sent to the °C video monitor unit 3Ω0 side through the terminals S, b; c, c; d, d of B. These three types of signals are input to the NTSC encoder circuit 33 via switch circuits 30, 31, and 32, and also to the synchronization signal line S1°. and one connector CN, each terminal a of CNIB.

A predetermined NTSC color video signal is created based on the subcarrier signals inputted through the synchronization signal line 55QQ. The same signal is applied to the output terminal 40 and inputted to the cNTsc display 65, and
An image corresponding to the image formed on 0D4 is displayed on the display 35. In this state, after adjusting the distance m of the photographing lens 1, adjusting the focal length, setting the composition, etc. while visually viewing the image on the display 35, when a release button (not shown) is operated, the image on the display 35 is recorded. That is, this recording is performed as follows.

After the shutter 3 is closed as the release button is operated, the CCD
4 light to 4 is performed. At the same time as this exposure operation, CC
D4 is two-dimensionally scanned by the horizontal scanning signal and vertical scanning signal from the synchronization signal generation circuit 604, and the output signal of the CCD 4 is amplified by the preamplifier circuit B and input to the signal processing (B) path 7. Then, the Y1 signal is output to the output terminal of the same circuit 7.

A (RY)+ signal and a (B Y)+ signal are generated, and these signals are sent to the recording/reproducing unit 200 side; Necta CN 2 people.

The signals are sent out through terminals S, b; c, c; d, and d of CN2B, respectively. Then, the Y1 signal is modulated by Pn1 by the luminance signal modulation circuit, and the near-7 assist is hidden. In addition, the (几-Y) signal and the (B-Y
The synchronization signal line S2o from the synchronization signal generation circuit 604 generates the signals Y)IfAr and CB-Y).

It is converted into a two-line sequential chroma signal based on the horizontal synchronization signal of 11. This chroma signal is subjected to low frequency conversion, PM modulation, and near-7 assist by the chroma signal modulation circuit 13. Then, the adder circuit 14 is mixed with the output signal of the f4 circuit 13, and the mixed signal is input to the recording amplifier circuit 15. The same circuit 15 performs processing such as recording equalization and white peak clearing, and the switch circuit 1
A recording signal is applied to the recording/reproducing magnetic head 18 via 6.

At this time, the synchronization signal line S2° is generated from the synchronization signal generation circuit 604. Since the vertical synchronization signal sent through is applied to the other control input terminal of the motor drive control circuit 23, the motor 21 rotates once per period (upper sand) of the vertical synchronization signal, and the detection The magnetic disk 19 is rotationally driven with its relative position with respect to the recording/reproducing magnetic head 18 being phase controlled by a signal from the PGEI 20 detected by the coil 22 . Magnetic recording is performed using the follower and PG yoke positions as reference positions.

On the other hand, when reproducing a signal recorded on the magnetic disk 19, the output of the mode switching circuit 9 changes from H level to L level by switching a switch (not shown). Then, the switch circuits 16°30, 31, 32 change from the operating state to the non-operating state, and each switch circuit 15.3
0, 31, 32 is the common end and normal as shown by the solid line.
The on end becomes conductive.

At this time, when the rotation of the magnetic disk 19 is controlled in the same manner as before, the magnetic reproduction signal obtained by the recording/reproducing magnetic head 181C is amplified to a predetermined level by the preamplifier 1 path 17 via the switch circuit 16, and the reproduction equalization, de-emphasis, etc. Processing is performed and a reproduced signal PB is obtained. This reproduction signal FB is sent to the video monitor unit 300 side via terminals e and e of connectors CN5B and CN3. The reproduced signal FB is then separated into a luminance signal component and a chroma signal component by a color separation m circuit 36. The luminance signal component at this time is FM demodulated by the luminance signal post-circular circuit 37 and subjected to a predetermined de-emphasis, Y2.
A signal is obtained, and this Y2 signal is input to the N'l'SC encoder circuit 33 via the switch circuit 30.

Further, the chroma signal component is FM demodulated by the chroma signal demodulation circuit 58 and subjected to a predetermined de-emphasis, and then is synchronized by the synchronization circuit 39.

A C color video signal is produced, and the signal is sent to the output terminal 40.
and is input to the NTSC display 35, and a reproduced image corresponding to the signal recorded on the magnetic disk 19 is displayed on the display.

Next, in the case of (2) above, that is, the recording/reproducing unit 200

31°52.16 is in a state where the common end and the normally-on end are electrically connected to each other, as shown by the solid line.

Therefore, unlike the previous case (υ), the output of the synchronization signal generation circuit 604 is sent out via the synchronization signal line 82001 S!00, and the motor 21 is driven to rotate as before by the vertical synchronization signal on the line 52oo. Then, the signal recorded on the magnetic disk 19 is
), the CY2 signal, (RY)2 signal, and (B-Y)2 signal are sent to the NTSC encoder via the switch circuits 50, 31, and 32.

- is input to the data circuit 33. At this time, unlike the case (1) above, the subcarrier signal input to the circuit 33 is the output from the synchronization signal generation circuit 604 of the relay connector 600, and the terminals a, ~an of the connector CN1 are connected to 'l'.
The signal is input from the synchronization signal line 53oo via the synchronous signal line 53oo. Then, a predetermined N'rSC color video signal is generated by the circuit 35Vc based on the subcarrier signal, and this signal is applied to the output terminal 40 and inputted to the NTSC display 35, and is converted into a signal recorded on the magnetic disk 19. A corresponding reproduced image is obtained.

If you want to record this reproduced image on another device, such as a video tape recorder, you can connect the video input terminal of the video tape recorder to the output terminal 40 of the video monitor unit 300, and record the reproduced image on a large video monitor TV. Even in the case of displaying images, the output terminal 40 may be connected to the video input terminal of the video monitor television, and the output of the output terminal 40 can be used in various ways.

Next, the operation in case (3) above, that is, when the imaging unit 100 and the video monitor unit 300 are combined and used as a video camera, will be explained using FIG.

Now, when the temperature recording mode is set by a switch (not shown) or the like, the output of the mode switching circuit 9 goes to H level, and the switch circuit 16 becomes inactive and connects to the 51C common terminal 16C as shown by the broken line. The normally-off end 16a is in a conductive state mJK.

Therefore, still images are recorded on the magnetic disk 19 in the same way as in the recording mode in case (1) above, but in this example, the half mirror 5o1 of the optical vinyl finder 500 is inserted into the mounting section 101. Therefore, the light beam that has passed through the photographic lens 1 is divided into two parts, one on the CCDJ side and the other on the finder screen 502 side. Then, the transmitted light of the half mirror 501 is incident on the CCD 4, and a still image is recorded on the magnetic disk 19 in the same manner as in the case (1) above. Further, the light beam reflected upward by the half mirror 5011c is directed to the finder screen 502.
After being imaged by the pentaprism 503, the positive! It is converted into an image, and a "C" object image can be observed through the eyepiece lens 504.

Since it is supplied to the electric circuits in 00 and 300, there is an advantage that the configuration is simplified.

In addition, in each of the above combination examples, [ is the imaging unit 100
Although a mounting portion 101 to which an optical vinyl finder 500 is attached is provided, it is of course possible to remove this mounting portion 101 and modify the device so that the finder 500 is not used. In addition, a video monitor unit 300
PA instead of the NTSC encoder circuit 33 built in
Of course, the encoder circuit may be replaced with an L or SECAM encoder circuit or an encoder circuit of a similar type. Further, the position of the shutter 3 may be in front of the imaging surface such as the C0D4, and it goes without saying that the imaging means such as the C0D4 may be electrically controlled instead of using the shutter 3.

Furthermore, when selectively coupling the units 100, 200 and 300 in the above embodiment, each connector CN1
Mu, CN1! I, CN2mu, CN2B, CN3
Of course, the CN5n may be further coupled via a relay couple instead of via the relay connector 600 or 700.

Further, the connector according to the present invention has the above-mentioned relay connector 60.
