Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic camera in which a disk 9 equipped with a frame number display is removably loaded into the main body of an electrophotographic apparatus m (hereinafter referred to as an electronic camera).

Some electronic cameras are equipped with a disk pack that can be loaded into the electronic camera body with a frame number indicator that displays the recording track number, or frame number, on the disk corresponding to the position of the head. be.

FIGS. 1 and 2 are diagrams showing a disk pack used in a conventional electronic camera of this type in relation to the electronic camera body. In FIGS. 1 and 2, zl 1 is a case of the disk pack, 2 is a disk-shaped recording disk rotatably housed in the case, and 3 is a rotating body side that fits into the center boss of the disk 2. 4 is a head on the main body side that is close to the recording surface of the disk 2 through the window of the case 1 so as to be able to record or reproduce information; 5 is a head that moves the head in the radial direction of the disk in synchronization with the rotation of the disk 2; A positioning mechanism 6 is a drive shaft 7 which is rotationally driven by the positioning mechanism 5 in accordance with the movement of the head 4.
is a frame number display which rotates with the rotation of the drive shaft and displays the frame number. This frame number display 7 is rotatably provided in the case of the disc drive, and on its surface is a symbol . . . indicating the recording track number (frame number) of the disc 2 corresponding to the head position. is attached. And the number indicating the current position is case 10 index 8
It is consistent with

In the above configuration, by checking the rotational position of the symbol ■■... provided on the frame number display 7 in relation to the index, the number of used frames from the inner circumference or outer circumference of the disc 2 can be determined. (number of tracks). However, the conventional frame number display means configured as described above merely displays the remaining number of unused frames. Therefore, if you remove the disk pack from the camera body before the disk 2 is used up, that is, in the middle of use, the used state of the pack will simply remain.1) Positional relationship with the head of the electronic camera body is almost bankrupt. Therefore, when the disk pack is used again, a special operation is required in order to precisely align the head 4 of the electronic mechanical device with the unused track.

This operation is extremely complicated and may cause problems such as erasing previous records. Therefore, if you want to save the recorded images on that disk pack, you will have no choice but to suspend the use of that disk/flat, even if that disk pack is only used for a very small amount of time. Also, when you want to select and play only a specific image out of all the images recorded in the entire recording area of the disc, you can quickly select the desired image without the hassle of selecting that image. There was also the problem that it was difficult to reproduce images of By specifying the frame number position on the display by external operation, recording or playback can be performed accurately from a track with any frame number at any time, making effective use of the disk recording capacity, and quickly selecting and playing back the desired image. Our goal is to provide an electronic camera that can

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

Fig. 3 is a perspective view showing the entire electronic camera, where 10 is the camera body, 20 is a disk arm loaded in the main body, and 30 is a control system connected to the disk 9◇ A camera body 10 is provided with a lens 11, a finder 12, etc., and a base 13 is provided with a window/te. The frame number display 21 of the disc pack 20 can be seen through this window/chi, and by operating the central axis 22 of the display 21 from the outside, you can specify any frame number position. It's something you can get.

4 and 5 are a front view and a side sectional view showing the structure around the frame number display 21. FIG. As shown in FIGS. 4 and 5, the frame number display 21 is disc-shaped.
The central shaft 22 is protruded from the center of its surface. Further, frame number characters 23 such as ■■... are provided on the outer periphery of the display 2, and a frame number information memory indicating each frame number information is provided at the angular position corresponding to each of these frame number characters 23. 1. In this embodiment, the code section 24 is configured to indicate, for example, 50 frame numbers in binary numbers using six small holes. The central shaft 22 has a wavy unevenness around it, and an annular plate 25 for eliminating the spring stop is fitted into this. This annular plate 25 has a hole in its center that allows it to be easily attached to and detached from the central axis 22, and has an angular position corresponding to the frame number ■■... of the frame number display 21 in the circumferential direction. A window 26 for erasing prohibition is provided for each. This window 26 is closed with a thin film so that when pressed lightly with, for example, the tip of a ballpoint pen, a hole is created through which light can pass.

The i-curve center portion of the frame number display 21 is fitted and fixed to the drive shaft 27, and rotates together with the drive shaft.

On the other hand, 28 is a line sensor for reading information. This line sensor 28 uses a light emitting element 28 so as to optically read only one line corresponding to one frame strangely shaped rock character among the code part 24 and erasure prohibition window 26 of the previous frame No. 6 display 21. The light-receiving elements 211B are arranged so as to face each other on the front side of the disc-shaped display 21.

The light emitting element 28fi and the light receiving element 28B are connected to a control system to be described later by a lead wire 29A and a lead wire 29B.

FIG. 6 is a diagram showing the main parts of the disk pack 20 and the control system 30 of the electronic camera body 10 in relation to each other. In FIG. 6, 2θA is a disk, 20B is a rotating shaft for rotating this disk, and 20C is a head. 3 is a step motor for driving the head, 32 is a step motor for moving the display, 33 is a motor for driving the disk, 34 is a disk rotation sensor, and 35 is a drive controller. It is composed of a well-known motor drive circuit, an f-motor drive circuit, and a microprocessor.

Thus, when a drive command is given to the terminal 36 of the ml device 35, a drive signal is supplied from the controller 35 to the disk drive motor 33, and the motor 33 causes the υ disk 20 to rotate.

The rotation of the disk 20A is detected by a magnetic or optical rotation sensor 34, and its detection output is used for driving.
11! It is supplied to the I controller 35. Then, the controller 35 applies one driving pulse to the step motors 3 and 32 each time the disk 20k rotates once. Therefore, the rotation of the step motor 31 causes the head 20C to move in the disk radial direction by one track pitch every time the disk 20k rotates once.The rotation of the step motor 32 causes the frame number display 21 to rotate by one step. do. During this time, the line sensor 28 does not operate because no operating signal is applied to it. When the recording or reproducing operation is thus stopped, the frame number display 21 displays the frame number corresponding to the track number on which the head 20C is located.

By the way, when the disk pack 20 is once removed from the camera body 10 from the above state and then loaded into the camera body 10 again, the positional relationship between the recording track of the head 20C and the disk 201' is almost impossible due to mechanical precision issues. It often falls apart.

Therefore, in such a case, operate the frame number display 21 from outside the main body and specify the frame number at which you want to restart recording. Then, information that this operation has been performed is given to the drive controller 35, The drive controller 35 enters the head position change mode. As a result, line sensor 28
becomes active and optically reads the code section 24 corresponding to the designated frame number. This read information is input to the drive controller 35. Then, the content of this input information is compared with the current head position in the drive controller 35, and a pulse train corresponding to the difference is sent to the head drive step motor 31. given to. Therefore, the head 2θC moves until the designated frame number information and head position information match. Then, once the above agreement is reached,
Since the head 20C stops, the head 20C ends up being accurately positioned at the frame rock position designated by the frame number display 21, that is, on the recording track.

In the head position change mode, no drive input is supplied to the step motor 32, so the frame number display 2 remains stationary until the coincidence is achieved.

When the above-mentioned coincidence is established, the drive controller 35 switches to the normal recording or playback mode, and switches the disk 20k as described above.
Each time the head 20C rotates once, the head 20C moves by one track pitch, and at the same time the frame number display 21 also rotates by one step.

On the other hand, when in the head repositioning mode, if you want to ensure that the contents recorded on the previously used track are saved, use the erasure prohibition annular plate corresponding to the corresponding frame number. Make a hole in window 26 of 25. Then, the line sensor 28 detects the position t of the frame number where the hole is located, and provides that information to the drive controller 35. Therefore, the head 20C jumps over the trunk of the frame number designated as erasing prohibited and moves to the next track 1. Thus, even if the frame number is specified incorrectly, the recording track to be saved will not be erased.

The timing, stopping, etc. of the above operations are executed by the microprocessor in the drive controller 35 according to a predetermined schedule.

According to the above embodiment, the following effects are achieved.

(2) Since the frame number display can be used to set the head position according to specified frame number information, appropriate recording can be performed on the desired track. Therefore, you can easily edit images.

■ You can use disk packs effectively by specifying unnecessary parts of previously recorded images and recording images that do not fit in those positions.

(2) By providing the annular plate 25 to prevent erasure, images to be saved can be kept safely.

■ Children who can record the number of holes in the annular plate 25 at a glance can use it effectively.

■ When playing back images, you can use the circular &25 holes in reverse to automatically play back only the prohibited (important) images.

- Since the annular plate 25 is removable, by replacing it with a new one, a used pack can be recorded from the beginning again.

(2) Even when the disk pack 20 is stored in the camera body 10, the frame number display 21 can be viewed from the outside, making it easy to know the remaining capacity of the recording section.

Therefore, it is easy to know when to replace the pack.

Note that the present invention is not limited to the embodiments described above. For example, as a frame number information memory, Fig. 7(a)
, (b), and those shown in FIGS. 8(a) and (b) may also be used. In the case of FIGS. 7(a) and 7(b), a reflective film 41 whose width gradually changes in the circumferential direction of the disc-shaped display 40 is provided,
This is an example in which the sensor 42 detects the magnitude of the amount of reflected light from the reflected light 41 and uses this as frame number information. In addition, in the case of FIGS. 8(,) and 8(b), a step portion 51 whose cylindrical height gradually changes in the circumferential direction of the disc-shaped display 50 is provided, and the change in the cylindrical height of the step portion 5 is controlled by a set of levers. In this example, the deviation detector 52 detects this, and the converter 53VC converts it into a stain signal, which is then used as frame number information. Furthermore, although the erasure inhibiting means in the embodiment described above utilizes the presence or absence of transmitted light, it may also utilize the presence or absence of reflected light as shown in FIG.

In FIG. 9, 6 is a light emitting element, and 62 is a light receiving element.

As explained above, according to the present invention, a frame number information memory is attached to a frame number display, and information in this memory is read when a specific frame number on the display is specified by an external operation, and the head is activated. Since it is configured to automatically move to the track corresponding to the specified number above, it is possible to not only display the number of unused frames remaining on the display above, but also change the frame number position on the frame number display. When designated by an external operation, recording or reproduction can be performed accurately from a track with an arbitrary frame number at any time. As a result, it is possible to provide an electronic camera that can effectively utilize disk recording capacity and quickly select and play back desired images.
