Abstract

PURPOSE: To easily and inexpensively obtain the reliability of the writing or reading of photographing information to a magnetic head by providing a pressing member for pressing a film to the magnetic head in such a manner as to be movable along the pressing direction. CONSTITUTION: A pad 7, which is a film pressing member having a smoothed surface, is formed out of an elastic member. A film 6 sent from a cartridge chamber 3a rushes into a pressure contact part between a magnetic recording regenerating head 1 mounted on a platen 2 opposite to the pad 7 and the pad 7. The pad 7 energized by a compression spring 9 is retreated as mus as the thickness of the film 6 to pass the film 6. The pressing force of the pad 7 depends on the repulsive force of the small-sized compression spring 9 which substantially precisely generates a constant pressing force in a displacement as fine as the thickness of the film 6. The pad 7 is held by the press-in of a pad holding member 8.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing apparatus having a magnetic recording / reproducing means having a pressure contact member for pressing a recording medium against a magnetic head for magnetically recording / reproducing.

[0002]

2. Description of the Related Art Recently, as disclosed in U.S. Pat. No. 5,122,821, a photographic film is provided with a magnetic layer, and film information such as photographing date, aperture, shutter speed and the like is used by a magnetic head. A camera for recording and reproducing has been proposed.

6 and 7 show an example of a conventional magnetic recording / reproducing unit. In FIG. 6, 3 is a camera body, 3a is a cartridge chamber, 3b is a spool chamber for winding a film by a film feeding means (not shown), and 1 is a pressure plate 2.
The magnetic recording / reproducing head 5 positioned and adhered to is a photographing lens barrel.

The photographed film has photographic information written under the frame photographed during the film winding from the magnetic recording / reproducing head 1 provided on the pressure plate 2 side. Therefore, in the case of a normal wind camera, if more information is to be written, the magnetic recording / reproducing head 1 will inevitably move to the left side from the camera rear surface.

FIG. 7 is a sectional view of a magnetic recording portion obtained by vertically cutting FIG. 6 around the magnetic recording / reproducing head 1. In FIG. 7, 3c is an aperture provided in the camera body, 3d is an inner rail portion that forms a film feeding gate with the pressure plate 2, 3e is an outer rail portion that forms the upper and lower ends of the film feeding gate, 4 Is a pad made of an elastic member, which is a film pressing member whose surface is lubricated.
It is adhered to the film feed gate recess between d and the outer rail portion 3e. Reference numeral 6 denotes a photographic film which is a medium for magnetic writing, and when the film passes between the pad 4 and the magnetic recording / reproducing head 1 by a feeding means (not shown), the elastic force of the pad 4 causes the magnetic recording / reproducing head. It comes to be pressed into contact with the gap portion of No. 1.

[0006]

However, the above conventional example has the following problems due to the structure of the magnetic recording / reproducing section.

(1) Since the film pressure contact force to the magnetic recording / reproducing head 1 is made to depend only on the elastic force of the pad 4 which is the pressing member, it is difficult to set and maintain the pressure contact force and the temperature change. It is directly affected by changes in pressure contact force due to changes in hardness of the elastic body itself. Therefore, the contact of the magnetic recording / reproducing head 1 with the photographic film 6, which is a medium, is not stable, and it is not possible to reliably write or read the photographic information to / from the magnetic recording / reproducing head 1.

(2) Since the pad 4, which is the pressing member, is directly adhered to the concave portion of the film feeding gate, it is easily peeled off due to surface friction with the photographic film 6.

(3) Since there is no retracting mechanism for the pad 4 which is the pressing member, when the photographic film 6 first enters between the pad 4 and the magnetic recording / reproducing head 1, it tends to be caught. Therefore, to improve this,
Even if the pad member as disclosed in Japanese Patent Publication No. 278042 is provided with a retracting mechanism for urging the pad member with a pressing spring, the pad retracting mechanism is used as the photographing lens barrel 5 and the spool chamber 3b.
It is difficult to arrange the camera so that the camera does not become large while securing the necessary area for the above, arrange the pad 4 outside the photographing area, and eliminate the leakage of light rays from the pad retracting mechanism.

(4) Since the pad 4 which is the pressing member is an elastic member, as shown in FIG. 7, not only the end surface of the film fed is easily caught on the end surface of the pad 4, but also the pad 4 is formed. It may be scratched or damaged and dust may be generated in the film gate.

A first object of the present invention is to easily and inexpensively obtain reliability of magnetic writing or reading of photographing information with respect to a magnetic recording / reproducing head.

A second object of the present invention is to prevent the pressing member from peeling or falling due to a film feeding frictional force.

A third object of the present invention is to make the pad retraction mechanism easy to assemble and arrange the pad retraction mechanism so that the light can be reliably shielded, thereby reducing the size of the camera.

A fourth object of the present invention is to provide a pad retreating mechanism which is less likely to be caught by the fed film and which does not damage the pad.

【Example】

(First Embodiment) FIG. 1 best shows the features of the present invention. In FIG. 1, the same reference numerals are given to the components having substantially the same names and functions as those of FIGS. 6 and 7 showing the conventional example. I am doing it.

FIG. 1A is a front view showing the arrangement of the pad retracting mechanism as viewed from the front of the camera. In this embodiment, the film is transferred from the cartridge chamber side 3a to the spool chamber 3
Each time the image is taken at b, it is sent by a film feeding means (not shown) and magnetically recorded. Assuming that magnetic information is recorded under the page of the film frame taken, the pad retraction is performed as shown in FIG. 1A in order to secure a large writing area and a space in the optical axis direction for the pad retraction. The mechanism is arranged in a triangular area indicated by X which is generated between the spool chamber 3b and the photographing lens barrel 5. If the camera of this embodiment carries out magnetic writing during film rewinding after shooting all the film, it is indicated by Y generated in the X region or between the cartridge chamber 3a and the photographing lens barrel 5. Either of the triangular areas may be used.

Even if the pad retracting mechanism is arranged in any of the X and Y regions, it will occur even if the photographing lens barrel 5 and the spool chamber 3b or the photographing lens barrel 5 and the cartridge chamber 3a are brought close to each other. Since the space is used, the lateral direction of the camera does not expand by incorporating the pad retracting mechanism into the camera. Further, since it is easy to secure a wide space in the X or Y region in the photographing optical axis direction that coincides with the pad retracting direction, the pad retracting mechanism can be arranged without waste.

FIG. 1 (B) is a cross-sectional view of the magnetic recording / reproducing section in the case where there is a pad retracting mechanism on the spool chamber 3b side (in the X area). In FIG. 1 (B), 3f is a slope portion provided in the film feed gate recess, and forms a slope from the film feed gate recess to the inner rail surface (see FIG. 2 described later). Reference numeral 3g denotes a pad insertion opening protruding in a box-bag shape in the X region of the camera body shown in FIG. 7
Is a pad made of an elastic member which is a film pressing member whose surface is lubricated, 8 is a pad holding member for holding the pad 7, and the pad holding member 8 is a box bag-shaped pad insertion port. A pad press-fitting portion 8a having a sawtooth-shaped projection is provided at the tip of the pad holding member 8 so as to be slidably fitted in the pad 3g, and the pad 7 is press-fitted into the press-fitting portion 8a.

Reference numeral 9 is a compression spring, which is dropped into a dowel 8c projecting in the rear recess of the pad holding member 8,
An elastic force is generated by being pinched and compressed between the pad-shaped holding member 8 and the lid-shaped fixed barrel 5a which is a part of the photographing lens barrel 5.
Also, by bonding the pad insertion opening 3g and the fixed barrel 5a, the pad insertion opening 3g becomes light-tight to prevent light leakage to the film. The dowel 8c is provided to prevent the spring 9 from falling when the spring 9 is assembled in the camera and when the pad holding member 8 retracts, and to provide a stable pressing force. The pad holding member 8 is in circumferential contact with the pad insertion opening 3g provided in the camera body and can move back and forth only in the optical axis direction. Also, the pad press-fitting portion 8a
The pad press-fitted into the pad has an outer shape that does not come into direct contact with the respective sliding surface portions of the pad insertion opening 3g of the camera body so that the pad can be smoothly moved forward and backward. Reference numeral 8b denotes a locking portion provided on the pad holding member 8, and when the pressure plate 2 is released from the camera body, the pad 7, the pad holding member 8, and the compression spring 9 that constitute the pad retracting mechanism by the elastic force of the compression spring 9 are provided. In order to prevent the protrusion from coming out from the pad insertion opening 3g, it is brought into contact with the stepped locked portion 3h of the camera body.

Reference numeral 10 denotes a spool which is a part of a film feeding means (not shown) provided in the spool chamber 3b, and a surface of which is wrapped with rubber which is an elastic body for facilitating generation of frictional force. . Reference numeral 11a is a rear roller spring integrally provided on the pressure plate 2 so as to have a rear roller 11b at its tip and press the rear roller 11b to the spool 10 side with a constant spring biasing force. Reference numeral 12a is a main body roller spring integrally provided in the fixed cylinder 5 so as to have a main body roller 12b at the tip thereof and press the main body roller 12b against the spool 10 with a constant spring biasing force.

Next, the operation of this embodiment will be described in detail with reference to the drawings.

FIG. 2 is a vertical cross-sectional view of the magnetic recording / reproducing section of this embodiment with the center cut vertically.

When the film 6 is fed from the cartridge chamber 3a by a film feeding means (not shown), the film 6 is vertically oriented to the outer rail 3e of the feeding gate and in the thickness direction to the inner rail 3d of the feeding gate. While being regulated by the pressure plate 2, the magnetic recording / reproducing head 1 attached to the pressure plate 2 so as to face the pad 7 and the pad 7 come into contact with each other.
The film 6 is sent while being curved so as to contact the concave surface 3i of the feeding gate and the aperture surface 3j (FIG. 3).
reference).

When the end surface of the film 6 reaches the inclined surface portion 3f, the end surface of the film 6 sunk in the film feeding gate concave surface 3i is lifted up to the inner rail surface by the inclined surface portion 3f. Further, when the end face of the film 6 is pushed into the press contact portion between the pressure plate 2 and the pad 7, the end face of the film 7 is very close to the press contact portion which is the tip end portion of the pad 7 and is parallel to the press contact surface. Therefore, it becomes difficult for the shearing force from the end surface of the film 6 to act on the pad 7 made of an elastic member, which is a film pressing member, preventing the pad 7 from being damaged and allowing the film 6 to smoothly enter the pressure contact portion. ing.

When the film 6 further enters the pressure contact portion between the pad 7 and the magnetic recording / reproducing head 1, the pad 7 urged by the compression spring 9 retracts by the film thickness,
The film 6 is passed. The pressing force of the pad 7 does not depend on the hardness of the pad 7, which is liable to change due to temperature changes, aging, and individual differences, but is small and generates a substantially constant pressing force at a slight displacement of the thickness of the film 6. Since it depends on the repulsive force of the compression spring 9, it is extremely easy to maintain and manage the pressure, and is easier to assemble than a conventional tension spring or the like which requires hooking at both ends. Further, the pad 7 is held only by press fitting on the pad holding member 8 and does not require adhesion, and since the press fitting length can be made long, the pad 7 which is an elastic body and the pad holding member 8 which is a resin or a metal molded product. Is sufficiently obtained, and the frictional force between the surface of the film 6 and the pad 7 can be sufficiently endured.

Further, when the film 6 is supplied, a frictional force between the surface of the film 6 and the pad 7 causes a force of pulling the tip of the pad 7 so as to incline in the traveling direction of the film 6. However, in the present embodiment, the pad holding member 8 holding the pad 7 is fitted to the pad insertion opening 3g of the camera body with the entire outer diameter, and is fitted in the pad 7 retracting direction for a long time. , The pad 7 is prevented from being rotated or agitated by the film 6 and the pressure contact between the film 6 and the magnetic recording / reproducing head 1 being displaced. Since the pad retracting mechanism is arranged in a light-tight state in which a sufficient light-shielding property is retained in the pad insertion opening 3g of the pad holding member 8 formed in a tubular shape, the pad 7 is provided near the aperture surface 3j. Despite the opening, it easily prevents light leakage from the front of the camera.

In FIG. 1B, when the film 6 is further fed, the leader portion of the film 6 contacts the rear roller spring 11, and the spool 10 and the rear surface which rotate in the winding direction by the film feeding means (not shown). Roller 11b
Sent between and. Further, when the film 6 is fed, it comes into contact with the main body roller spring 12a, is fed between the rotating spool 10 and the main body roller 12b, and the film 6 is completely wound up on the spool 10.

(Second Embodiment) FIG. 4 shows a second embodiment according to the present invention.
3 is a central transverse section of a magnetic recording / reproducing head showing the embodiment of FIG. In the figure, the same components as those in the first embodiment are designated by the same reference numerals and the description thereof is omitted. A pad holding member 13 integrally includes an elastic portion 13b, and has a press-fitting portion 13a which is a pad holding portion at the tip. The elastic portion 13b compressed between the fixed barrel 5a of the photographing lens barrel and the magnetic recording / reproducing head 1 presses the pad 7 as it is, and its function and effect are substantially the same as those of the first embodiment.

(Third Embodiment) FIG. 5 shows a third embodiment of the present invention.
3 is a central transverse section of a magnetic recording / reproducing head showing the embodiment of FIG. In the figure, the same components as those in the first embodiment are designated by the same reference numerals and the description thereof is omitted.

4 is integrally provided with an elastic portion 5b on the side of the fixed cylinder 5a forming the substantially bag-shaped pad insertion opening 3g, and the elastic portion 5b is made to face the rear recess of the pad holding member 14. The function and effect are almost the same as those of the first embodiment. It should be noted that any of the above-described embodiments has the advantages of reducing the number of parts and improving the assembling property.

(Fourth Embodiment) FIG. 8 shows a fourth embodiment according to the present invention.
6 is a central transverse sectional view of the magnetic recording / reproducing head showing the embodiment of FIG. Incidentally. In the figure, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, a pressing portion 15a is provided in a portion corresponding to the pad 7 such that the press-fitting portion 8a of the holding member 8 itself is in the shape of a pad, and one of the pressing portions is fitted in the film pressing direction with the photographing apparatus main body. The pressing fitting member provided with the fitting portion 15b is provided. When the magnetic head 1 does not exist in the pressing direction (the pressure plate 2 is not attached to the photographing device), the pressing fitting member has an abutting portion 15c that is pushed out by a spring and can abut the locked portion 3b. ing. Since the operation and the function are the same as those in the first embodiment, the description thereof will be omitted.

The difference between this embodiment and the first embodiment is that the hardness of the pressing portion must be increased by integrating the pad and the holding member (the fitting portion can be smoothly Since it is slid, it is difficult to integrally mold the elastic material as it is.) The precision with which the film, which is the medium, and the magnetic head adhere closely decreases. However, since the press-fitting portion can be integrally formed of, for example, a resin having good surface lubricity, the cost is low, and the end face of the film sent to the film gate hits the end face of the pad 7 made of an elastic body. Not only is there no risk of the pad buckling, but the pad 7 is not damaged by the film.

Further, since the pressing fitting member is integrated, the fitting length to the photographing device can be made longer, and it is stronger than the first embodiment against the inclination of the pressing portion due to the friction due to the film feeding. it can.

In the figure, the same components as those in the first embodiment are designated by the same reference numerals and the description thereof is omitted. In this embodiment, the elastic portion 13b in the second embodiment is deleted from the pad holding member 14 as shown in FIG.
The elastic portion 5b is integrally provided on the side of the fixed cylinder 5a that forms the substantially bag-shaped pad insertion opening 3g into which the pressure fitting member 17 is fitted. The function and effect are substantially the same as those of the fourth embodiment.
