<Examples> Examples of the present invention will be described below with reference to the accompanying drawings. The embodiment shown here is applied to the handy camera of the present invention. First, referring to FIGS. 1 to 3, the camera is indicated by CA in the drawings. TL is a taking lens, 1 is a focusing ring, and 2 is an operation rod for zooming. Reference numeral 3 denotes a half mirror for extracting light from the fiber, which is arranged behind the photographing lens L in the camera body. Reference numeral 4 denotes a half mirror for taking out the photometric light, which is arranged in the optical path reflected from the mirror 3, and a photometric element 5 is arranged so as to receive the reflected light of the mirror 4. 6 is a total reflection mirror,
A fiber optics system having a well-known configuration is disposed behind the. 7 is an eye cup for the finder. Reference numeral 8 denotes a photographing diaphragm, which is arranged behind the mirror 3 and has a structure in which the diaphragm can be cut off. Reference numeral 9 denotes a CCD image sensor as a solid-state image pickup element, and a well-known frame transfer type two-dimensional image pickup CCD is used here.
As will be described later, a lenticular lens and a color stripe filter are arranged on the front surface of the image pickup section of the CCD 9 as is well known. Reference numeral 10 denotes a cartridge storage chamber of the camera CA. As shown in the drawing, a magnetic recording cartridge 12 in which a magnetic recording disk 11 is rotatably accommodated is housed therein.
Is loaded. The cartridge 12 is, as shown in FIG.
A disk 11 is rotatably supported by a shaft 12a, and a central opening 12a for receiving a disk drive spindle 14 on the side of the camera CA is provided in a part of its housing.
Similarly, a slot 12c for receiving the magnetic head 15 provided on the camera CA side is formed. As shown in FIG. 1, the disk 11 has a center hole 11a, is rotatably supported by the shaft 12a in the center hole 11a, and is an arc-shaped slot concentric with the center hole 11a. It is biased toward the central opening 12b side by a leaf spring 13 having 11b and provided in the cartridge 12. Here, as shown in FIG. 2, the depth of the loading chamber 10 is depressed, and the loading of the cartridge 12 is as shown in FIG. 2 with the cartridge loading chamber lid 16 open. As shown by the phantom line, it is inserted at an angle, and at this time, the spindle 14 is inserted into the central opening 12b and the magnetic head 15 is inserted into the slot 12c in the direction of the arrow in the drawing. Therefore, the head 15 is loaded in a normal position, and at this time, the tip of the head 15 contacts the magnetic recording portion 11c of the disk 11. This recording unit 11c can set a plurality of, for example, 40 recording tracks in a state where they are separated from each other, and a magnetic signal for one frame of a still image is recorded in each track as described later. Further, the disk 11 itself has flexibility, and the elasticity thereof allows the head pressure of the head 15 to be obtained. When the loading chamber lid 16 is closed, the cartridge 12 is positioned by the leaf springs 17 and 18 (second shown) attached to it. The disk drive spindle 14 has a drive pin 14a engageable with the arc-shaped slot 11b of the disk 11,
The flywheel shaft 19a is connected to the shaft 19a of the wheel 19, and the flywheel shaft 19a is supported by the bearing metal member 20 at the boss portion 21 of the camera frame so as not to cause rotational backlash and thrust backlash. . It should be noted that the problem of rattling of the shaft 19a has an extremely large effect on the recording performance, and thus it is necessary to pay particular attention.

M ₀ is a motor for driving the flywheel 19 to rotate, and a rubber belt 23 is stretched between the output pulley 22 and the flywheel 19. Reference numeral 25 is a head holding member that holds the head 15 at a bending arm portion 25a at its tip, and is a support attached to a part of the camera frame along the slot 12c of the cartridge 12 It is slidably supported by the rod 24 along the rod 24 and is urged by the spring 26 in the direction shown by the arrow in FIG. It has ratchet teeth 25b formed so as to define the intervals of the magnetic tracks in the recording portion 11C.
In the state where the head holding member 25 is displaced by the spring 20 to the final end position in the direction of the arrow in FIG. 2, the magnetic head 15 becomes the outermost track in the recording portion 11c of the disk 11. Each element is designed to correspond. In this case, the number of the ratchet teeth 25b is, for example, 40 according to the set number of tracks in the disk 11. Therefore, the total number of set positions of the head 15 is 41. 27 is a ratchet feed pawl for engaging the ratchet tooth 25b and shifting the holding member 25 by one tooth, and is biased by a spring 28 in the direction of engaging the ratchet tooth 25b. It is phosphorus-bonded to the movable armature Am of the plunger Pl.
The plunger Pl, depending on the current flow,
Against the spring 29, the holding member 25 is designed to be projected by a stroke capable of accurately shifting by one tooth. Reference numeral 30 denotes a locking claw for holding the holding member 25 at the fed position, which is rotatably supported by a shaft 31 erected in a part of the camera frame, and ,
It is biased by a spring 32 in a direction to engage with the ratchet teeth 25b. 33 is the holding member when the loading chamber lid 16 is opened
25 is a reset member for automatically returning the head 15 to the initial position where the head 15 is in contact with the outermost track on the disk 11, and has a hook portion whose head is cut into a taper or arc shape, It is attached to a part of the lid 16 so that the hook portion can engage with the tail end 30b of the locking claw 30. Therefore, when the lid 16 is removed, at this time, the locking claw 30 is rotated against the spring 32 by the reset member 33, and at this time, the feeding claw 27 is also fixed to the tip of the locking claw 30. The protrusion 27a at the tip thereof is pushed by the head portion 30a and is rotated against the spring 28 with the link connecting point with the armature Am as a fulcrum.
Both are disengaged from the ratchet teeth 25b, whereby the holding member 25 is automatically returned to the initial position described above. The reset member 33 has some flexibility, and when the lid 16 is opened by a certain angle or more, the engagement with the locking claw 30 is released, and when the lid 16 is closed, When the head collides with the tail end 30b of the locking claw 30 and rides over it, the hook portion is set to a position where it can engage with the tail end 30b. Therefore, the tail end of the locking claw 30
As for 30b, it is preferable to round the edge portion as shown in FIG.

In FIGS. 1 and 3, 34 is a release button, which is a so-called two-stage release type here. Reference numeral 35 is a grip part, in which a power supply battery E is housed. Further, in FIG. 1, EU is an electric circuit unit, the details of which will be described later. Further, in FIG. 3, numeral 36 is a dial for mode selection, which can be switched to indices "S", "C ₁ ", "C ₂ " and "MV". Here, the meaning of these indexes is that "S" is one image shot,
"C ₁ " is a continuous image shot at a speed of, for example, 7.5 images per second, "C ₂ " is a continuous image shot at a speed of, for example, 3.75 images per second, and "MV" is a speed of 30 images per second, that is, , Each represents a video shot at a general video recording speed. (Note that shooting means shooting). 37 is a slide for selecting the shift of the head 15 with respect to the recording track between the automatic and the manual, which can be switched between the index "A" and "M", and the index "A". Indicates automatic shift, and “M” indicates manual shift. Reference numeral 38 denotes a push button for shifting the head 15 when the manual shift mode "M" is selected, which can operate the plunger Pl depending on the circuit configuration described later. In addition, head 15
It is obviously irrational to manually shift the values in the modes "C ₁ ", "C ₂ " and "MV", so that here, for example, as shown in FIG. ₁ "," C ₂ "
And "MV" prohibits the slide 37 from changing from "A" to "M" and allows this change only in the mode "S", and when the slide 37 is in the "M" position. A cam 39 is provided so as to automatically reset the slide 37 to the “A” position when the mode is changed to “C ₁ ”, “C ₂ ”, or “MV”. This cam
39 is made to face the follower portion 40a of the pin-slot engagement plate 40 on which the slide 37 is provided. Reference numeral 41 is a click stop spring. or,
The reference numerals of the modes shown in parentheses for the cam 39 indicate the area of the cam corresponding to each mode.

Returning to FIG. 3 again, 42 is a jack for external output of the video signal (NTSC signal), to which a general VTR device can be connected, and this is especially when the mode is set to "MV". used. That is, the number of image frames that can be recorded on the disk 11 is at most 40 according to the above example, and therefore, even if an attempt is made to record a moving image on the disk 11 at the video recording speed, it will end in about 1 second,
Also, even if the number of tracks on the disk is increased, there is naturally a limit to it, so it is unreasonable to use the disk to perform a video shot in the first place. If 42 is provided, it will be possible to shoot for a long time depending on the combination with the VTR device, and the camera function will be further expanded.
43 is a jack for remote control, to which a remote controller is connected.

The above is the configuration of the main part of the camera CA. Next, the details of the circuit configuration of the electric circuit unit EU will be described.

First, FIG. 5 shows the structure of an image pickup-video signal (NTSC signal) generation-magnetic recording system, in which 44 is an oscillating circuit for generating a relatively low frequency clock pulse of KHz order and 45 is the oscillating circuit. Synchronous control circuit that generates various synchronous control signals required for synchronously controlling the circuit system shown here based on the clock pulse from 44, 46 generates a relatively high frequency clock pulse of MHz order An oscillating circuit, 47 is a CC based on a clock pulse from the oscillating circuit 46 and a CCD synchronous drive control signal from the synchronous control circuit 45 (this is based on, for example, a vertical synchronous signal).
It is a sync driver that outputs various signals required to drive D9 synchronously. Incidentally, here, the CCD 9 is, as schematically shown in FIG. 6, an imaging section (light sensitive section) 9a composed of a large number of optical sensor elements arranged in a matrix.
In order to transfer the charges stored in the storage unit 9b, which captures the charges corresponding to each pixel accumulated in the image pickup unit 9a and stores the charges corresponding to the addresses of the elements, in time series. As is well known, except for the image pickup section 9a, all of them are shielded from light, and the front side of the image pickup section 9a is colored as shown in FIG. A stripe filter 48 and a lenticular lens 49 are arranged. Among the signals given to the CCD 9 from the sync driver 47, there are signals for controlling charge accumulation in the image pickup unit 9a, charges accumulated in the image pickup unit 9a at a predetermined timing, for example, The clock pulse for transferring to the storage unit 9b in an extremely short time at the timing of every 1/60 seconds, and the charge taken in the storage unit 9b through the shift register 9c for 1/60 seconds (this is A clock pulse, etc. for outputting all in time series (that is, reading out the stored electric charge) is included during 1V-1 vertical scanning on the television), and this The timings of the equal signal and the pulse are defined based on the control signal from the synchronization control circuit 45. Although not shown in FIG. 6, the shift register
Needless to say, the electric charge transferred in 9c is finally converted into a voltage or a current and then output. Since this type of frame transfer type CCD is already well known, further detailed description will be omitted.

Now, returning to FIG. 3 again and continuing the explanation, 50 and 51 are CCD9s.

Reference numeral 52 denotes a video signal (NTSC signal) generation circuit, and a luminance signal circuit 53 that outputs a luminance signal Y according to the output from the sample and hold circuit 50,

Based on the signals Y, RY, BY from these circuits 53, 54, NTS
The color signal output circuit 54 and the encoder 55 are provided with a sync control signal from the sync control circuit 45, as is well known. Incidentally, since it is well known that the video signal generating circuit of this type is already known, only the display according to the function block will be described here. Reference numeral 56 is a magnetic recording circuit for video signals. In this example, a low pass filter 57, a pre-emphasis circuit 58, an FM modulation circuit 59, and a high pass filter.
A well-known so-called color sub-carrier low-frequency conversion multiplex recording system consisting of 60, band pass filter 61, frequency conversion circuit 62, low pass filter 63, mixing circuit 64 and recording amplifier 65 is adopted. . Although the operation function of a circuit adopting this system is already well known, the brief mention here is that when an NTSC signal, that is, a composite color video signal is first input from the video signal generation circuit 52, this video The luminance signal Y and the color subcarrier signal fc of 3.58 MHz are separated from the signal by the low pass filter 57 and the band pass filter 61, respectively. The separated luminance signal Y is pre-emphasized by the pre-emphasis circuit 58, FM-modulated by the FM modulation circuit 59, and then the high-pass filter 60.
Is applied to the mixing circuit 64 as an FM luminance signal excluding a part of the lower side band, while the color subcarrier signal fc is applied to the frequency conversion circuit.
At 62, after balanced modulation by the signal fn of the predetermined frequency from the synchronization control circuit 45, the difference signal, that is, the low-frequency conversion color subcarrier signal fs-fn-fc is taken out by the low-pass filter 63. To the mixing circuit 64, and by the mixing circuit 64,
A signal (that is, a VTR signal) obtained by mixing the color signal on the low-frequency conversion color subcarrier fs and the FM luminance signal excluding a part of the lower band is obtained, and is obtained through the amplifier 55. It is recorded on the track of disk 11 by leaning to head 15.

Next, a first concrete example of the sequence control system according to the present invention will be described with reference to FIG. In the example shown in FIG. 10, one magnetic head is used both for unrecorded track detection and for recording, and the operation mode is appropriately switched by using the output of the counter CNT _1. It is possible to automatically detect whether or not there is a recording at a position to be recorded without using a dedicated detection head. In the figure, 15 is a magnetic head for detection and recording, which is the analog switch ASW and the unrecorded track detection circuit (that is, amplifier AP, signal division circuit HI).
C and a comparator COM) connected to an analog switch ASW 'provided at the input stage of the analog switch ASW', which depends on the inverter IV ₄ of the signal to be applied to the analog switch ASW. It is designed so that the inpart output is attached. Therefore, according to this circuit configuration, when the output of the counter CNT ₁ is low, the analog switch ASW ′ is turned on and the head 15 ′ is used for detecting the unrecorded track, and this time with the unrecorded track is detected, this time the output of the counter CNT ₁ is set to the high analog switch ASW is the head 15 'is turned on is used for recording to yet-recorded track.

9 is a photometric circuit that determines an appropriate aperture value based on the charge accumulation time of the image pickup unit 9a in FIG. In the present embodiment, this accumulation time is uniquely defined by the time factor in the control signal given from the fifth illustrated sync control circuit 45 to the sync driver 47. According to the description, the fixed time is about 1/60 second, and in this case, therefore, the photometric circuit PMC is provided with fixed information about this time. By the way, this time corresponds to the exposure time of the film in the case of a camera using a general silver salt film, and therefore the PMC of this photometric circuit can directly adopt the photometric circuit configuration of a known film camera. is there. Reference numeral 66 is a diaphragm driving means such as a meter or a motor which adjusts the diaphragm 8 to an appropriate diaphragm value in response to the output of the photometric circuit PMC, and its output shaft is connected to the diaphragm 8. As described above, the diaphragm 8 in this case has a so-called diaphragm-cutting structure (this is the so-called “burn-in” of the CCD 9).
The purpose of this is to prevent this from happening. For example, when a meter is used as the diaphragm driving means 66, a spring is applied to the movable coil and the coil is used. When the power is not supplied to the diaphragm 8
Should be held in a fully squeezed state,
Also, when using a motor, it is necessary to connect a storage means such as a capacitor to this and to give the stored power to this storage means when the output from the photometric circuit PMC is cut off. It may be arranged so that the diaphragm 8 can be forcibly driven so as to be cut down.

Reference numeral 67 is a scale member for displaying the aperture value, which is driven together with the aperture 8 by the aperture driving means 66, such as a transparent film having aperture value scales, which is a visible position in the camera / finder. The aperture 8 is arranged so as to display the aperture value adjusted by the matching of the scale with the fixed index 68.

Its ON-OFF signal is given whenever the excisional input S of the differentiating circuit DFC and Furitsupu-Furotsupu FF ₁ have through the inverter IV _2. Note that the flip-flop FF ₁ is set only after the switch SWR ₂ is turned on, its output becomes low, and this output is provided to the base of the transistor Tr _1. When 34 is pushed down to the second stage, the transistor Tr ₁ is held, and even if the release button 34 is released immediately, the transistor Tr ₁ does not become non-conductive. When the switch SWR ₂ is off and the detection head 15A detects a recorded track, this hold is released and the track is disconnected.

The cycle of C output is 1 / 3.75 sec, and AND gate AG ₅ ,
Since the high level time of AG ₆ output and A output is 1/30 sec, each output is set to mode “S”, “C ₁ ”, “C ₂ ”.
, And the outputs of these outputs A and AND gates AG ₅ and AG ₆ depend on the switch AW ₃ which is linked to the dial 36, and the modes "S" and "C", respectively. ₁ ", it has been made as to be selected by the" C ₂ ". Note that this switch the output of the counter CNT ₁ is selected by the SW ₃ imaging configuration as displayed in FIG. 5 - Video signal generator - an output stage of the magnetic recording system circuit 69 (i.e., the fifth illustrated amplifier circuit
65) is attached to the analog switch ASW for recording control provided between the head 15 and the head 15, and the recording is controlled by this. Further, the clear terminal CL of the counter CNT ₁ have been made as the Q output of Furitsupu-Furotsupu FF ₂ is given whenever, the Q output becomes possible only counted if a row.

La ₂ depends on the transistor Tr ₂ which receives the Q output of the flip-flop FF ₂ at its pace. When the Q output is low,

It is connected to the collector side of the transistor Tr _{3 in} the mode “M” by the switch SWM ₁ which is interlocked with. The switch SWM ₁ connects the plunger Pl to the collector of the transistor Tr _{3 in} the mode "A".

The SWE is a normally-closed end switch that is opened at the end of recording on all tracks on the disk 11, and is connected in series with the transistor Tr ₁ . Incidentally, it would be reasonable to use, for example, the configuration shown in FIG. 7 as a configuration for activating the end switch SWE. That is,
In the structure shown in the figure, the tail end of a part of the camera frame is
A track / count member 72 pivotally attached to the head 72 and swinging in response to the feeding of the holding member 25 by engaging a pin 71 set up in the head holding member 25 with a slot 72a in the middle thereof. Is provided so that the number of recorded tracks can be displayed on the track number scale plate 75 arranged in the window 74 by the pointer 73 attached to the tip of the counting member 72. Is shifted to the left in the figure by the number of all the teeth of the ratchet tooth 25b, that is, the innermost track of the recording portion 11c of the disk 11 is disengaged and further shifted inward by one tooth. At this time, the end switch SWE can be opened by the switch opening protrusion 76 at the tip of the counting member 72. The fifth
The power supply to the circuit system shown is controlled by the transistor Tr ₁ as in the photometric circuit PMC.

Now, next, the operation of the camera having the above-described electric system formation will be described. As described above, in this camera, "S-A" (1 image shot-automatic head shift), "SM" (1 image shot-manual head shift), "C ₁ " ( There are 5 modes: 7.5 images / sec continuous shot), "C ₂ " (3.75 images / sec continuous shot) and "MV" (video shot depending on VTR speed using VTR device). However, in order to facilitate understanding, first, regarding the case of the mode “SA”,
A description will be given with reference to the timing chart in the figure.

First, the state in which the camera CA is loaded with the cartridge 12 so that all the tracks of the disk 11 are unrecorded (at this time, the head 15 is set to its initial position as described above, end-switch SWE is also turned on.), when the dial 36 is in the "S" mode position, the switch SW ₁ is turned on state, also, the switch S
When SW ₂ is open, switch SW ₃ is counter CNT.
Connected to A output terminal of ₁ . Also, slide 3 in this state
Setting the 7 "A" mode position, the camera CA switch SWM ₂ is in an open state with the switch SWM ₁ is connected to Puranjiya Pl side is "S-A" mode.

In this state, when the camera CA is aimed at the desired object while looking through the finder, and the release button 34 is first depressed to the first stage, the release switch SWR ₁ is turned on and the transistor Tr ₁ becomes conductive. Therefore, the photometric circuit PMC is activated, the aperture 8 is adjusted from the aperture stop state to an appropriate aperture value, the lamp La ₁ is turned on, and the scale plate 67 is illuminated.
Further, the motor M ₀ is started and the disk 11 is rotationally driven. This state is shown in FIGS. 9 (a), (b), and (d).
~ (F). Further, when the transistor Tr ₁ becomes conductive, a pulse is output from the one-shot pulse circuit OSP as shown in FIG. 9 (g), which causes the flip-flop FF ₃ to perform power-up clear and flip-flop. Flops FF ₁ and FF ₂ are reset and set, respectively, and their outputs and Q output become high as shown in FIGS. 9 (h) and 9 (i). On the other hand, transistor Tr ₁
When is turned on, power is supplied to the fifth circuit system shown in the figure to start driving the CCD 9, and image pickup-video signal generation-VTR signal output starts. At this time, the synchronization control circuit 45 a vertical synchronizing pulse as shown in (k) in FIG. 9 is the counter from CNT ₁
However, the counter CNT ₁ is
Cleared because the Q output of Flop FF ₂ is low,
That is, the pulse is not counted at all because it is restricted to the uncountable state, and therefore the A output is low as shown in FIG. 9 (l) and the analog switch ASW remains off. At this time, the clock pulse is applied from the oscillator circuit 44 to the counter CNT ₂ . or,
When the time required for the motor M ₀ to rise to the steady speed elapses after the transistor Tr ₁ is turned on, the output of the delay circuit DLC becomes high as shown in FIG. At that point, one input of AND gate AG ₁ goes high.

Also, at this time, since the disk 11 is completely unrecorded, no signal component appears in the output of the detection head 15, so that the output of the comparator COM becomes low as shown in FIG. 9 (n). ing. Therefore, the plunger Pl is not energized, and the head 15 is held at the initial position, that is, the position in contact with the outermost track in the recording portion 11c of the disk 11. Also, at this time point, one input of the AND gate AG ₁ becomes high due to the output from the inverter IV ₁ .

Now, in this state, when the release button 34 is pushed to the second stage (shown in FIG. 9 (a)), the release switch SWR ₂ is turned on as shown in FIG.
The output of inverter IV ₂ is inverted from low to high through DFC, thus setting flip-flop FF ₁ and the output of AND gate AG ₂ is high at this time, so the set input of flip-flop FF ₃ is set. The AND gate A to S
The output of G ₂ is applied and the flip-flop FF ₃ is set, and its Q output becomes high as shown in FIG. 9 (m). This causes AND gate AG _{1 to} have its output high at this point because all three inputs are high,
Therefore, since the Q output of the flip-flop FF ₂ is inverted to low as shown in FIG. 9 (i), the counter CNT ₁ is released from its clear and starts counting the input pulse.

When the output of the inverter IV ₂ is inverted from low to high, the flip-flop FF ₁ is set and its Q output becomes low as shown in FIG. 9 (h), so that the transistor Tr ₁ is kept conductive. At this point, even if the release button 34 is released at this time, the circuit system is not cut off from the power supply and the following operation is continued.

Now, when the counter CNT ₁ starts counting its input pulse and its A output becomes high as shown in FIG. 9 (l), the analog switch ASW is turned on by this, and the amplifier circuit shown in FIG. The output of 65 is applied to the memory head 15 ', so that the signal for one frame of the target image is magnetically recorded on the outermost track of the disk 11. Here, the A output at this time is obtained by dividing the vertical synchronization signal (FIG. 8 (a)) from the synchronization control circuit 45 by two in this embodiment as described with reference to FIG. , Its high-level time is one cycle of this vertical synchronizing signal, that is, 1/30 second, while this 1/30 is well known in the fifth illustrated circuit system.
Since the readout of the CCD output is repeated twice in succession within 30 seconds, the signal of 2 fields and 1 frame is magnetically recorded on the track of the disk 11. or,
Therefore, the motor control circuit M ₀ is designed to be controlled at a constant speed of 1800 rpm.

In this way, after the A output of counter CNT ₁ goes high, 1 /
After 30 seconds, the A output goes low again and the analog
The switch ASW is turned off, and during this period, the recording of the signal for one frame on the track of the disk 11 is completed by the two-field method. At this time, the output of the comparator COM becomes high as shown in FIG. 9 (n), and by this,
The output of AND IV AG ₁ goes low because the output of inverter IV ₁ goes low. Also, the comparator C at this time
The flip-flop FF ₂ is set by the high output of OM, and its Q output becomes high as shown in FIG. 9 (i).
As a result, the counter CNT ₁ is cleared and is held in a count-disabled state, so that its A output remains low after the end of recording as shown in FIG. 9 (l), and the analog switch ASW is also turned off. It will remain. Further, when the output of the comparator COM becomes high, the output pulse from the AND gate AG _{4 is applied} to the base of the transistor Tr ₃ through the AND gate AG ₃ , so that the transistor Tr ₃ becomes conductive and the plunger Pl becomes conductive. Therefore, the head holding member 25 is moved by the feeding pawl 27 shown in FIG.
Since only one tooth of b is sent, the head 15 'is a disk 1
It becomes shifted to the second track of 1, and here, since the disk 11 is completely unrecorded, the output of the head 15 'has no signal component, so that the output of the comparator COM is the first. As shown in FIG. 9 (n), at this point, it is inverted to low. When the output of the comparator COM goes high, the flip-flop FF ₃
Is reset. Further, when the output of the comparator COM becomes high, the flip-flop FF ₁ is reset and its output becomes high as shown in FIG. 9 (h), so that the conduction holding of the transistor Tr ₁ is released. Therefore, if the release button M is released at this point and the release switches SWR ₁ and SWR ₂ are off, the transistor Tr ₁ becomes non-conductive and power supply to all circuit systems is cut off. Like Regarding the timing of releasing the release button 34, for example, as shown by A in FIG. 9 (a), after the switch SWR ₂ has been pushed to the second stage, that is, the switch SWR ₂ is once turned on. After that, the transistor T is driven by the movement of the flip-flop FF ₁ as described above.
Since the continuity of r ₁ is maintained, the camera automatically performs the above-mentioned operation and stops at the time when the shift of the head 15 'to the second track is completed.
As shown by B in the figure, if the button is pressed down to the first step but not released to the second step, the camera releases the release button 34 because the transistor Tr ₁ is not held conductive. It will stop immediately when you do.

The explanation is mixed up, but the flip / flop FF ₂
While the Q output of which is a row, i.e., during recording, the transistor Tr ₂ is turned, the lamp La ₂ is lit, therefore, that it is being recorded, becomes as displayed.
It is convenient to arrange this lamp La _{2 so} that its lighting can be visually recognized in the finder.

In this mode "SA", the camera stops or waits in the state where the head 15 'is automatically shifted to the next track after the recording of one frame is completed. Thereafter, the above operation is repeated each time the release button 34 is pressed down to the second step, and the image signals for one frame are sequentially recorded on each track of the disk 11.

The number of recorded tracks at this time is sequentially indicated on the track number scale plate 75 by the pointer 73 attached to the tip of the seventh illustrated counting member 72. Further, when the recording on the innermost track of the disk 11 is completed and the head 15 'is automatically shifted, the end switch SWE is opened by the projection 76 at the tip of the counting member 72, and the whole circuit system is opened. Power will be cut off momentarily.

The above is the case where the disk 11 is not recorded at all, but, for example, when a recorded cartridge is loaded up to a track in the middle, the following will occur. That is, first,
If the first track on disk 11 was already recorded,
When the switch SWR ₁ is turned on and the motor M ₀ is started, the output of the comparator COM becomes high, so the recording is prohibited as mentioned above, and the plunger Pl is energized and the next The truck shift is performed.
Also, at this time, the output of the inverter IV ₁ becomes low, so even if the flip-flop FF ₁ is set at this time, that is, even if the switch SWR ₂ is closed, its output remains low. , Therefore, flip-flop FF ₃
Is not set. On the other hand, if the new track is not recorded at the time when the head 15 'is shifted, the prohibition of recording is canceled because the output of the comparator COM becomes low, and the AND gate AG ₂ Since the output of is high and the flip-flop FF ₃ is set, the signal for one frame is recorded in this new track as described above. If this new track has already been recorded, Since the output of the comparator COM remains high, the head 15 'is shifted to the next track while the recording is prohibited.

Therefore, if you use a cartridge that some of the tracks have already been recorded, the recording is prohibited for the already recorded tracks and the heads are recorded without double recording.
The automatic shift of 15 'is performed, and only when the unrecorded track is detected, the unrecorded track is recorded.

The above is the case where the mode is "SA", but next, in the case of mode "SM", that is, in the case of one image shot-manual head shift, slide 37 is moved to the "M" position. By switching, the switch SWM ₁ is switched from the plunger Pl side to the lamp La ₃ and the push switch SWP is connected to the plunger Pl via the switch SWM ₂ so that the track with which the head 15 'is in contact. it is detected that is already recorded, the head 15 that abutment track of 'the, following automatic shift to track lit lamp La ₃ momentarily instead not performed head 15' is already recording Will be displayed in advance. In this case, it is possible to shift the head 15 'to the next track by depressing the push button 38 and turning on the switch SWP.

Therefore, in this mode "SM", first, the head
If the 15 'contact track is unrecorded from the beginning,
Even if recording is performed in the same manner as above depending on the camera release, even if the output of the comparator COM goes high at the end of this recording, the lamp La ₃ will light for a moment and the head 1
The shift of 5'to the next track is not carried out, in this case the shift of the head 15 'is carried out by throwing in the push switch SWP. On the other hand, since the abutment track of head 15 'is lamp La ₃ when a previously recorded from the start to light a moment, if introduced here switch SWP head 1
5'is shifted to the next track, and if this track is unrecorded, it is recorded in this unrecorded track. Of course, if this track has already been recorded, the lamp La ₃ will light again for a moment and a warning will be issued, so eventually, until the head 15 'reaches the unrecorded track, the warning will be repeated depending on the lighting of the lamp La ₃ , and the push Only when the head 15 'reaches the unrecorded track by repeatedly pressing the button 38, the unrecorded track is recorded.

Next, in the mode "C ₁ " or "C ₂ ", that is, in the case of continuous image shot, the switches SW _{1 to} SW _{3 are} operated by switching the dial 36 to the position of the mode "C ₁ " or "C ₂ ". Switches to the mode "C ₁ " or "C ₂ " terminal.

Therefore, the differentiation circuit DFC is short-circuited by the switch SW ₂ , and the flip-flop FF ₁ remains set while the switch SWR ₂ is on, and the second button of the release button 34. As long as the contact track of the head 15 'is a non-recorded track, the recording is not prohibited and the recording is continued and a continuous image shot is performed while the button 15' is pressed to the eye. Of course, in this case, as can be understood from the operation in the above-mentioned mode "SA", if there is a recorded track in the middle, the output of the comparator COM becomes high at the time of detecting the recorded track, As a result, the flip / flop FF ₂ is set, the counter CNT ₁ is cleared (that is, the recording is prohibited), the plunger Pl is energized, and the head 15 ′ is automatically shifted to the next track. If this track has not been recorded, the track is recorded. This operation is continued as long as the release button 34 is pressed down to the second step.

The conduction of the transistor Tr ₁ is maintained in the same manner as the above case. The output of the AND gate AG ₅ is selected by the switch SW ₃ in the case of the mode “C ₁ ”, and the output of the AND gate AG ₆ is selected by the mode “C ₂ ”. As explained with reference to Fig. 10 in the case of mode "C ₁ ", a continuous shot of 7.5 images / sec., And in the case of mode "C ₂ ", a continuous shot of 3.75 images / sec. Become.

By the way, in this camera, an external output jack 42
If an R device is connected and the dial 36 is set to the mode "MV", a movie shot at a normal VTR speed, that is, a speed of 2 fields-30 frames / second is possible. That is,
When dial 36 is set to mode "MV", switch SW
_{All of 1 to} SW ₃ are switched to the mode "MV" terminal, and in this case, therefore, the release button 34 is pushed to the first stage, and the switch SWR ₁ is turned on.
69 operates to output an NTSC signal from the jack 42, whereby magnetic recording is performed in the VTR device in a known manner.

In the embodiment described above, the head is mechanically shifted with respect to the track of the disk 11, but finally, the magnetic head is changed to a multi-channel head corresponding to the number of tracks of the disk 11. For this reason, see Fig. 11 for an example in which this is fixed and the channels can be discriminated at the end of each track and the unrecorded tracks can be recorded by sequentially switching the channels. And explain. It should be noted that FIG. 11 shows only the configuration of the main parts for obtaining the above functions, and other necessary parts will be described with reference to the configuration of FIG.

In the figure, CNT ₃ is a counter with a built-in decoder for channel shift, and its clear terminal CL is provided with the output of the one-shot pulse circuit OSP. IV ₅ is an inverter for obtaining an inversion signal of the output of the one-shot pulse circuit OSP, OC is one that is triggered by the rising edge of the output of the inverter IV _5.
The short circuit OG ₄ is an OR gate designed to receive both the output of the one-shot circuit OC and the Q output of the AND gate AG ₃ , and the output of the OR gate OG ₄ is a count up.・ It is designed to be attached to the clock input terminal CK of counter CNT _{3 as} a clock.

15 _{1 to} 15 n are fixedly provided so as to correspond to the respective tracks of the disk 11, and the heads for detecting the recorded tracks and the recording heads, which have a so-called multi-channel head structure, ASW ' _{1 to} ASW'n are analog switches connected to the respective heads 15 _{1 to} 15n, all of which are the input stage of the recorded track detection circuit, that is, an amplifier.
Connected to AP. ASW _{1 to} ASWn are heads 15 ₁ to ₁ respectively
Analog switches connected to 5n, both of which are connected to the output stage of the imaging-video signal generation-magnetic recording system circuit 69. AND _{1 to} ANDn are respectively the A output of the counter CNT ₁ or the output of the AND gate AG ₅ or AG ₆ selected by the switch SW ₃ and the respective outputs 1 to 1 of the counter CNT ₃ .
an AND gate for taking an AND between n, the output of each of which is given whenever the respective analog switches ASW ₁ ~ASWn.
The analog switches ASW ' _{1 to} ASW'n are provided with the outputs 1 to n of the counter CNT ₃ , respectively.

According to the above configuration, first, when the one-shot pulse circuit OSP outputs one-shot pulse as shown in FIG. 9 (g) in the first stage of the release, the counter CNT ₃ Then, the power amplifier clear is applied to all of the outputs 1 to n to become low. Then, when the one-shot circuit OC is triggered by the output rise of the inverter IV ₅ at this time and one-shot pulse is output,
This causes the counter CNT ₃ to count up by one and its output 1 goes high first. Therefore, now with the mode set to "C ₁ " or "C ₂ ", the counter
When the output of the CNT ₁ is assumed to be low, the analog switch
Only ASW ' ₁ is turned on and the output of the detection head 15 ₁ is applied to the amplifier AP. If the first track with which the heads 15 ₁ and 15 ₂ are in contact is unrecorded, the output of the counter CNT ₁ becomes high as described above.
The output of gate AND ₁ goes high, thus recording head 15
Becomes as is recorded in the first track depending on the ₁ is carried out. When this recording is detected that the detected head 15 ₁ ends became already recorded, AND gates in the same manner as described above
Since the Q output of AG ₃ goes high, counter CNT
₃ counts up by 1 and then output 2 goes high, so this time analog switch ASW ' ₂ turns on, so the second track is unrecorded, depending on the detection head 15 ₂ . Whether or not it is detected and if it is not recorded, the second track is recorded by the recording head 15 ₂ when the output of the counter CNT ₁ becomes high in the same manner as described above. Also, if it is already recorded, the Q output of the AND gate AG ₃ becomes high, and accordingly, the counter CNT ₃ counts up by 1 and its output ₃ becomes high, and accordingly, the _third output.
When the above-mentioned detection is performed on the track, and eventually the mode is “C ₁ ” or “C ₂ ”, as in the case of the above-described embodiment, as long as the release button 34 is pressed, the unrecorded track is not recorded. The recording to will be repeated.

The mode is the case of "S" after completion of recording to unrecorded tracks, while the Q output of the AND gate AG ₃ is the counter CNT ₃ depending to become high is that one count up, Furitsupu · Furotsupu FF ₃ of the camera depends on tilt becomes deactivated, and after releasing the depression of the release button 34 once, and pressing again, starting from the detection head 15 _1, the detection head 15 to the unrecorded track is detected ₁ ~ 1
When 5n channel switching is performed and an unrecorded track is detected, recording is performed according to the recording head corresponding to this track.

In addition, A of the counter CNT ₁ selected according to the switch SW ₃
The output or the invert signal of the output of AG ₅ or AG _{6 by} the inverter IV ₆ is input to the AND gates AND ′ _{1 to} AND′n which take the AND with the respective outputs 1 to n of the counter CNT _3. The outputs of AND ' _{1 to} AND'n are provided to the analog switches ASW' _{1 to} ASW'n, respectively.

According to the configuration shown in FIG. 11, as shown in FIG.
No mechanical configuration for head shift is required. When this configuration is adopted, "A"-"M"
Configuration for switching, i.e. slide 37 and push
It would be inconvenient to have buttons 38 and switches SWM ₁ , SW ₂ and SWP. Incidentally, in this case, the lamp for La _3, if this was connected to the collector of the transistor Tr ₃ to go like, count up-counter CNT _3, i.e., state of channel switching of head 15 ₁ ~15n Will be displayed.

Regarding the display of the number of already recorded tracks when the configuration shown in FIG. 11 is adopted, for example, as shown in each figure,
Decoder driver and Seven segment LE for display
A display unit DU consisting of D is provided, and the display unit DU
It may be possible to display digitally by providing outputs 1 to n of the counter CNT ₃ to the decoder inside, or else an LED dot array display consisting of n LEDs. It would be better to display with a dot number using. Especially in this case, it is convenient to do it in the display camera / finder.

As a configuration for controlling the end switch SWE, for example, the base of a transistor TR ₄ having an electromagnet Mg connected to its collector side as shown in the figure is connected to the (n + 1) th output terminal of the counter CNT _3. Stay, this n + 1
It may be sufficient to energize the electromagnet Mg when the output goes high, and thereby open the end switch SWE.

In the embodiment, as the image pickup-video signal generation-magnetic recording system circuit adopted in the apparatus of the present invention, a configuration using a CCD image sensor as an image pickup element is shown. It goes without saying that there is no problem in using an image tube such as a videocon in the past. As for the recording medium, although a magnetic disk is shown in the embodiment, a magnetic drum or the like can be easily used by slightly modifying the mechanical portion of the camera CA.

<Effects of the Invention> According to the present invention described above, when the user first operates the first switching means by sequentially operating the operation members while holding the housing of the apparatus, the image pickup means is operated. Since the image pickup operation is started and the recording means is set to the recording standby state in which the image signal can be immediately recorded, the image signal can be immediately recorded when the second switching means is operated by operating the operation member. As a result, the image can be recorded with good operability of both the image pickup means and the recording means while supporting the casing without releasing the hand from the casing and without delaying the timing of actual recording. Further, if the recording means is set to the recording standby state, the recording operation of the image signal is blocked even if the second switching means is operated, so that unstable image recording may occur. Therefore, reliable image recording can be performed.
