Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an electronic camera (electronic photographic device), and particularly to the structure of an electronic camera (electronic photographic device).

<Prior Art> Recording and reading information on a moving information storage medium, such as magnetic recording, requires relative movement between the recording/reading head and the storage medium.

The relative velocity between the head and the storage medium surface can be approximately 13.97 meters per second, such as for video. To achieve maximum performance, the recording/reading head and the media surface must be in close contact and in contact without destroying or excessively abrading the magnetic field-sensitive coating on the recording media. You must do so.

Therefore, the conventional method of bringing the recording/reading head into close contact with the medium surface is to increase the contact pressure between the head and the storage medium, but this method is undesirable because it causes severe wear on the medium and the head. This problem is especially serious when the head is in continuous contact with the storage medium for one frame in order to present a still image in video. That is,
For example, if the storage medium is made of a magnetic disk, and this magnetic disk is rotating at 3600 rpm, then if a static image is presented for 5 minutes, the same track on the magnetic disk will be rotated approximately 18,000 times. The close contact between the magnetic disk and the head very quickly wears down the tracks on the magnetic head, destroying the information magnetically stored on the tracks.

Several methods have been proposed to solve this problem between the head and the disk. One of them is to use a hard flat magnetic disk and a floating head that floats relative to the magnetic disk. Another method is to soften the large surface head and bury it in a flexible "floppy" magnetic disk.
However, the former method requires a hard material as the substrate forming the magnetic disk, which is usually made by plating aluminum with a thickness of about 0.254 μm and coating it with a material sensitive to magnetic fields such as nickel-cobalt. and 0.127μ for wear protection.
It is coated with m rhodium plating. Magnetic disks formed in this way are very expensive, and the magnetic head is suspended by an air cushion when the disk rotates at full speed to prevent excessive wear. It is necessary to configure The distance between the magnetic head and the magnetic disk is normally required to be between 0.889 and 1.27 μm, and the delicate balance of the force that keeps the magnetic head floating against the surface of the magnetic disk is required to prevent fine dust. Disturbances can occur due to particles or finger squeezing, which can cause the magnetic head to violently collide with the magnetic disk.

Magnetic disks of this type therefore cannot be handled without gloves and are usually handled in a special clean room environment and usually sealed in an empty container. In order to avoid this collision between the magnetic head and the magnetic disk, increasing the flying height of the magnetic head with respect to the magnetic disk will reduce the risk of head damage, but since the distance will be greater, the performance will be limited except for low frequency digital applications. deteriorates. As can be seen from the foregoing, the method of using a hard magnetic disk and having the head levitated over the magnetic disk is unsuitable for low cost, high capacity consumer applications such as video recording.

On the other hand, the latter method can solve the problems of handling and price in magnetic disk devices that are problems with the former method, but it is still difficult to use the recording/reading magnetic field for floppy magnetic disks. The head is relatively large to provide an interface consisting of a large profile head embedded in a soft, flexible medium. The large surface area of the read/write head reduces force per unit area, which helps reduce media wear and distance loss, so air collects between the magnetic head and the drum as the media moves past the magnetic head. to form a thin film. The thickness of this air film is a function of the tension of the medium, the radius of the head surface, the viscosity of the air, and the relative speed of the disk head, approximately as follows.

h=0.642 [6 μv/T] h: Thickness of air film R: Radius of head surface V: Relative velocity T: Media tension μ: Viscosity of air Therefore, most flexible or “floppy” magnetic disks Applications are limited to low-speed, low-bandwidth digital computer applications. Therefore, flexible or "floppy" magnetic disks have not been used in conventional video.

However, recently, even when flexible magnetic disks are used in electronic photographic devices such as video cameras and electronic image reproducing devices, it is possible to avoid excessive wear on the recording surface of the magnetic disk and the magnetic head. An apparatus including a flexible magnetic disk is proposed which enables continuous long-term recording and playback of broadband signals from the flexible magnetic disk without sacrificing performance. can be seen, for example, in Japanese Patent Application Laid-Open No. 109914/1983.

It goes without saying that this mechanism is suitable for using the surface 7B of the housing 7' as an entry surface, and can be commonly applied to the electronic photographic device and the electronic image reproducing device. However, as an example, Figures 9 to 12
A case where the present invention is applied to the electrophotographic apparatus shown in the figure will be explained as an example.

In FIG. 14, the handling device 6' is loaded into the device storage chamber 76 with the front surface 7b of the handling device 6' being the entry side. 77 ₂ ′ is a positioning pin that is engaged with the positioning hole 7c ₁ of the device 6′ when the device 6′ is loaded, and the positioning pin 77 ₂ ′ is always attached toward the inside of the storage chamber 76 by the spring 31.

In the mechanism configured in this manner, when the device 6' is not loaded in the storage chamber 76, the head 91, the rotating shaft 83, and the positioning pin ₇₇₁ ' are moved into the storage chamber 76 by the biasing force of the plate spring 36. It stands out. When the device 6' is loaded into the storage chamber 76, the positioning pin _{771' is first pushed upward by the tapering surface 761 of} the loading device 6' against the biasing force of the leaf spring 36. In conjunction with the push-up operation of the positioning pin 77', the head support member 33 moves upward via the fork member 32, and the head 91 begins to exit from the storage chamber 76. Further, in response to the upward movement of the plate spring 36 due to the withdrawal of the positioning pin 77', the rotary shaft 83 is also pushed up by the plate spring 36, and the groove 82'a of the pulley 82' and the rotary drive shaft 83 The engagement with the upper member ₈₃₁ is released.

A power transmission relationship is formed between the two.

In this way, in this embodiment, as the device 6' is loaded, the magnetic head 91 and the rotary drive shaft 83
The teeth 85 escape out of the storage chamber 76 to facilitate the loading of the device 6', and only when the device 6' is fully loaded into position can the magnetic head 91 be attached to the device 6' with the teeth 85. Since it is set to the device 6', it is possible to insert the device 6' from a direction perpendicular to the axis of the rotary drive shaft 85.

Note that 36 shown in FIGS. 15 and 17 is a pen that is attached selectively or from the beginning to the magnetic head 91, and the pen 91 visually traces the trajectory of the magnetic head 91 on the magnetic disk 9. The used track on the magnetic head 91 can be determined by matching the part written with this pen 91 to the scale 7f that is graduated along the extension direction of the opening 7b in the device 6'. It makes it possible.

FIG. 18 shows that while the magnetic head in the electrophotographic device and the electronic image reproducing device described above was of a movable type, the magnetic head shown in this embodiment is of a fixed type. It consists of a magnetic head device 91' in which a plurality of magnetic heads ₉₁₁ ' to _91o ' are arranged in the radial direction of the disk 9. When the devices 6, 6' are loaded, the magnetic head device 9
Each of the magnetic heads 91 ₁ ′ to 91 _o ′ of 1 enters the openings 7 b and 7 b ′ of the devices 6 and 6 ′, and the magnetic heads 91 ₁ ′ to 91 _o ′ come into contact with the magnetic disk 9. . Reference numeral 92 denotes the magnetic heads 91 ₁ ' to 91
A plurality of switches 9 connected in pairs with _o ′
The switches 92 ₁ to 92 _o of _the switch device ₉₂ are sequentially controlled by a known switch selection device.

That is, the switch 92 ₁ of the switch device 92
~ _92o receives a selection signal from a switch selection device, and if the input signal is a signal that turns on switch ₉₂₁ , magnetic head 91' is enabled, and the other switches ₉₂₂ ~ _92o are disabled. placed.
Then, when the input signal from the switch selection device turns on the switch ₉₂₂ , the magnetic head ₉₁₂ ' becomes effective, and the other switches _921,9
23 to _92o are sequentially controlled so as to be in an invalid state, and if a signal to turn on switches ₉₂₁ and ₉₂₂ is input, switches ₉₂₁ and ₉₂₂ are simultaneously enabled and others are controlled. switch 9

That is, the switches ₉₂₁ to _92o are controlled in various ways according to the output signals from the switch selection signal device, and each magnetic head of the magnetic head device 91' paired therewith is respectively enabled. Information is then stored on the surface of the magnetic disk 9 that is in contact with the enabled magnetic head, or information stored on the surface of the magnetic disk is reproduced.

Therefore, such a multi-magnetic head device 91'
If this is used, the magnetic head can be moved every time the track on the magnetic disk 9 changes, as in the magnetic head device used in an electrophotographic device or an electronic image reproducing device shown in FIGS. 9 to 17. Since there is no need to move the magnetic head, a mechanism for moving the magnetic head is not required.

In the embodiment described above, FIGS. 9 to 1

That is, the storage chamber 76 for storing the magnetic disk 9 and the viewfinder 69 for observing the subject are arranged horizontally so that they are not lined up vertically toward the subject in the normal photographing position (shown in Figs. 9 and 12). are juxtaposed.

Therefore, the height of the camera can be lowered compared to a case where the storage chamber and the viewfinder are arranged vertically, and according to this embodiment, the storage chamber can be gripped in normal use. This allows for an easy-to-use shape.

<Effects of the Invention> According to the present invention, as an efficient arrangement of an electronic camera, the storage chamber for the recording medium and the viewfinder for observing the subject image are arranged horizontally so that they are not lined up vertically facing the subject at the normal shooting position. Since the height of the camera in the normal shooting position is limited by placing them side by side, it is possible to downsize the electronic camera.Furthermore, the viewfinder optical system and the recording medium are placed side by side, and the viewfinder and the storage chamber for the recording medium are placed side by side. However, it is possible to make the electronic camera into a shape that is easy for the user to hold and use.
