Abstract

PURPOSE:To prevent the expansion of the hole for positioning a jacket by composing to turn up to the position almost in parallel with a device itself when a jacket holder is pushed with the opening and closing cover and is shifted to the loading position, and after that, by entering the device itself by shifting in parallel. CONSTITUTION:When a jacket holder 10 turns togehter with an opening and closing cover 11, the jacket holder 10 becomes almost the horizontal condition. Further, since a rubber roller 47 is pushed down at the inside of a opening and closing cover 11 when the opening and closing top 11 is pushed downwards, a bracket 46 falls by making resistance to a spring 131 while the jacket holder 10 is hold. Thus, the jacket holder 10 falls a little in the horizontal condition and shifts to the loading position mounted on a device body 12. When the jacket holder 10 is set to the device body 12, a rubber roller 122 fixed to the opening and closing cover 11 enters the front part while the roller presses the front end of a magnetic sheet jacket 6.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an electrophotographic camera that records photographed scenes on a magnetic sheet. This relates to a jacket holder that has been improved so that it rotates until it becomes , and then moves in parallel.

[Prior art]

When recording still images, it is common to use a photographic camera using silver halide photographic film, but recently so-called electrophotographic cameras that record images electrically have been proposed and are attracting attention. This electrophotographic camera is comprised of an imaging device that takes an image of a subject, and a magnetic recording device that modulates a video signal output from the imaging device and records it on a magnetic sheet.

As the electrophotographic camera, for example,
As described in Publication No. 1696, if a magnetic sheet jacket containing a rotatably magnetic sheet is loaded into the jacket holder and the opening/closing lid is closed, the jacket holder moves to the loading position where it overlaps the main body of the device. . When the salmon throat holder is set at the loading position, the magnetic sheet mounting means provided to protrude from the main body of the apparatus detachably holds the magnetic sheet, and the magnetic head comes into contact with the recording surface of the magnetic sheet. When recording a video signal, the magnetic sheet is rotated at high speed by the magnetic sheet mounting means, and one frame of the video signal is recorded in 11 ranks by the magnetic head.

In order to correctly position the magnetic sheet at the loading position, two holes are formed in the jacket that rotatably stores the magnetic sheet, and these holes connect to the positioning pins protruding from the main body of the device. Fit together. The conventional jacket holder described above is rotatably supported by the main body of the apparatus, so that it rotates and moves to the loading position when pushed by the opening/closing lid. Therefore, since the jacket socket 1- moves in a circular motion and fits into the positioning pin, the hole in the plastic jacket expands as it is used, making it difficult to properly set the magnetic sheet jacket in the device body. become unable to do so.

(Object of the Invention) An object of the present invention is to provide a jacket holder for an electrophotographic camera that prevents the hole in the jacket from being enlarged.

A magnetic sensor 116 that detects the reference position detection protrusion 84a and generates a pulse is inserted into the opening 113a, and is attached to the plate 113 with a pair of screws 117. Further, a regulating plate 118 is fitted into the opening 113b to provide appropriate sheet travel so that the magnetic field 58 obtains a good output signal.
It is attached to the plate 113 with a pair of screws 119 so that it does not come out. A groove 118a extending in the moving direction of the magnetic head 58 is formed on the lower surface of the regulating plate 118.

Also, attached to the inside of the inner lid 16 are a spring plate 120 for pushing the magnetic sheet jacket 6 downward and a rubber roller 122 rotatably supported by a support plate 121 having nine elasticities. Furthermore, a spring 126 is attached to the shaft 125, and its tip fits into the groove 43 of the lock lever 41. A torsion coil spring is used for this spring 126, and two-dimensional acting forces, that is, a force in the original opening direction and a force in the direction of pressing the lock lever 41 toward the jacket holder 10 are utilized.

As shown in detail in FIG. 7, the tip of the spring 126 is
When the opening/closing lid 11 is completely opened, the first resting part 70a
, and when it is completely closed, it is located at the second rest part 70b. When the opening/closing lid 11 is closed, the spring 126
When the tip of the jacket holder 10 starts moving from the first resting part 70a and moves to the loading position where the jacket holder 10 overlaps the apparatus main body 12, it reaches a point 70c. Since the protrusion 41a is provided behind this point 70C, the tip of the spring 126 is at the second resting part 70 at this position.
cannot move to b. Between the point 70C and the point 70d, only the opening/closing lid 11 rotates, and during that time, the leaf spring 20 (see FIG. 9) attached to the inner lid 16 pushes the ring 82 of the magnetic sheet 80 and secures it to the pulley 53. to fit. Then, at point 70d, the spring 126 rotates clockwise by its own elastic force and moves to the second resting point 70b, and at the same time, the mouth/pick pin 18 is locked by the hook lever 8. Said second rest n[7o b
is provided to the left of the rotation center 127 of the lock lever 41, so the spring 126 biases the lock lever 41 clockwise in FIG. Remove from 97. Note that the distance l between the first resting part 70a and the point l-70d is the distance over which the opening/closing lid 11 can move relative to the salmon/throat holder 10. Therefore, in FIG. 5, the opening/closing lid 11 is intentionally left wide open so that the inside can be clearly seen.

When the opening/closing lid 11 is released, the opening/closing lid 12 and the jacket holder 10 rotate together, and when the jacket holder 10 reaches the unloading position, the opening/closing lid 11, which is now biased by the spring 128, rotates. Only it opens a little. When only this opening/closing lid 11 is opened, the tip of the spring 126 is
It moves within the guide groove 43 from the resting part 70b toward the first resting part 70a. Here, between point 70b and point 70e, since the bottom surface is inclined so that point 70e is shallower, the sliding resistance at the tip of spring 126 gradually increases, and the opening/closing lid 11 opens slowly. . When the opening/closing lid 11 is slowly opened, the rubber roller 122 retreats from the front surface of the magnetic sheet jacket 6, so that the magnetic sheet jacket 6 whose rear end is pressed by the ejecting spring 36 is ejected from the jacket 6. At this time, the rubber roller 122 rides on the magnetic sheet jacket 6 and rotates, so that the magnetic sheet jacket 6 is slowly discharged. After the magnetic sheet jacket l-6 is ejected, the tip of the spring 126 passes the center 127, so the lock lever 41 is biased counterclockwise in FIG. Point 70a is reached.

Therefore, the lock lever 41 is activated only when the opening/closing lid 11 is completely open and completely closed.
will be provided with a locking function. Note that between the second resting point 7Qt+ and the point (~70e), there is a point "10".
Since e is inclined so that it is shallower, spring 12

You can prevent it from going to the ``number'' and move it to the correct italic position.

The pair of arm portions 30 and the bracket 46 are overlapped, and a shaft 130 passes through them, and the spring 128 is wound around the shaft 130t.

As shown in FIG. 10, the bracket 46 is inserted into the hole 74 of the device main body 12, and is biased upward by a spring 131 housed therein. Rubber roller 47
When pressed by the opening/closing lid 11, the bracket 1-46 can be lowered while compressing the spring 131. In this way, by making the bracket 46 movable up and down, the jacket holder IO is placed in a horizontal state before being placed on the main body 12 of the apparatus, so that the holes 98 and 99 formed in the jacket 81 are aligned with the positioning pins 70 and 70. It can be inserted into these from directly above 71. Generally, when the jacket 81 is rotated and fitted onto the positioning pins 70, 71, a lateral force is applied, so that the hole 98° 99 of the plastic jacket 81 is widened laterally. However, in this embodiment, such a problem does not occur because the jacket 81 moves up and down and fits into the positioning pins 70, 71. Note that reference numeral 133 is a plate for preventing the spring 131 from being removed.

The stopper 134 is provided so as to be slidable by a certain distance, and is pushed up when the jacket holder 10 is opened, and when the stopper 134 moves by the distance, the jacket holder 10 rotates against the leaf spring 73. , and position the jacket holder IO in the unloading position.

FIG. 8 is a sectional view of the magnetic recording unit. A motor 140 for rotating the spindle shaft 50 is housed in a cylindrical portion 141 of the device main body 12 so as to be movable up and down.
Coil spring 1 prevented from coming out with cap 142
43, and its upper end abuts against the shoulder 144. Therefore, if the magnetic sheet jacket 6 is improperly loaded or a foreign object is found in the jacket holder 10, an excessive downward load is applied to the magnetic sheet mounting portion 51, but the spindle shaft 50 and motor 140 Since the coil spring 143 is compressed while retreating, the spindle shaft 50 is not given an i-shape or the motor 140 is not damaged.

As shown in an enlarged view in FIG. 9, the magnetic sensor 116
1 includes a main body 150, a coil 151 housed in the main body 150, and an iron core 1 disposed so as to pass through the coil 151.
52.

A screw shaft 153 is fixed to the upper end of the iron core 152, and the screw shaft 153 is engaged with the main body 150. Therefore, by turning the screw shaft 153, the iron core 152 moves in the axial direction, so that the sensitivity can be adjusted to a desired value by changing the distance from the reference position detection protrusion 84a.

[Effect of the embodiment]

Next, the operation of the embodiment of the present invention will be explained with reference to FIGS. 10 to 14. When the opening/closing lever 7 is slid in the direction shown by the arrow in FIG. 1, the engagement between the lock pin 18 and the hook lever 8 is released. The opening/closing lid 11, which is pivotally supported by the opening/closing lid 11, is pushed by the plate spring 73 and opens together.

After both have rotated together to the position where the jacket holder 10 is locked by the stopper 134, only the opening/closing lid 11 is further rotated by the weak spring 128 toward the position shown in FIG. It stops at a position regulated by the regulation plate 107. When only this opening/closing lid 11 rotates,
The tip of the spring 126 passes from the second resting part 70b of the groove 43 of the lock lever 41 to the first resting part 70e through the point l-70e.

The reinforcing ring 82 is located close to the reinforcing ring 82 such that the distance between the reference position detection protrusion 84d and the reference position detection protrusion 84d is approximately 0.4 mm.

After adjusting the focus and determining the composition, when the release button 5 is pressed, the motor 140 rotates at a high speed of 360 rpm, and the video signal read by the imaging device is modulated and sent to the magnetic head 58. During the rotation of the magnetic sheet 80, leakage magnetic flux from the permanent magnet 54 passes through the reference position detection protrusion 84a to the iron core 152 of the magnetic sensor 116.
Since the magnetic flux density across the coil 151 changes as it crosses below the coil 151, a pulse is generated in the coil 151. The magnetic head 58 starts recording the video signal at a timing synchronized with the pulse output from the magnetic sensor 1j--116. Therefore, recording of the video signal is started from the starting point of the track of the magnetic sheet 1-80, and one frame worth of video signal is recorded in one trunk. In this way, when the magnetic recording of one frame is completed, the pulse motor 59 rotates a certain amount so as to make contact with the outer track, and the moving stage 56
The magnetic head 58 is fed in steps through the. At the same time, the counter disk 95 is rotated by a certain amount by the counter drive shaft 63, and the number of recorded tracks is displayed.

When the video signal has been recorded in all 50 frames, that is, all 50 tracks as described above, if you slide the opening/closing lever 7 in the direction of the arrow to unlock the opening/closing lid 11, the strong leaf spring 73 The opening/closing lid 11 and jacket holder 10 open together. In this case, since the bracket 46, which is attached to the main body 12 of the apparatus, is pushed up by the spring 131, the jacket holder 10 is vertically lifted from the main body 12 of the apparatus, and thereafter rotates around the shaft 130. . When this jacket 10 is lifted vertically, the jacket holder body 25
Since the flat jacket support part 26 is located on the side of the main body 12 of the apparatus, the almost front surface of the lower surface of the magnetic sheet jacket 6 and the cylindrical part 82a of the ring 82 are pushed up, and the magnetic sheet jacket 6 is smoothly attached to the pulley 53. It can be removed from Therefore, the magnetic sheet jacket 6 has
Since no complicated force is applied to warp the magnetic sheet 80, the extremely thin magnetic sheet 80 will not be deformed.

The jacket holder 10 rotates while lifting the stopper 134, and when it reaches the unloading position, the stopper 134 stops moving and cannot rotate any further. When the jacket holder IO is stopped at the unloading position, only the opening/closing lid 11 is rotated a little further by the weak spring 128. When the opening/closing lid 11 rotates away from the jacket holder 10, the rubber roller 122 retreats from the front surface of the magnetic sheet jacket 6, so that the lock lever 41
The magnetic sheet jacket 6 which has been released from the lock is pushed out by the ejecting spring 36, as shown in FIG. At this time, the rubber roller 122 rides on the upper surface of the magnetic sheet jacket 6 and rotates, so that the magnetic sheet jacket 6 (slowly discharged). It can be pulled out from the holder 10.

Note that the spring plate 84 is placed across the opening of the shunter 91.
When pulling out the magnetic sheet jacket 6 from the jacket holder 10, there is a part of the shunter 9 inside.
1 is left behind by the pressing force of the splash plate 84, and as a result, the shutter 91 moves to the closed position and closes the window 89.

The sensitivity of the magnetic sensor 116 becomes higher as the screwing amount of the iron core 152 is increased and the closer it is to the reference position detection protrusion 84a. The screwing amount of this iron core 152 is MIN.
When knotting or adjusting the regulation plate 118, or when replacing the magnetic sensor 116 or regulation plate 11B,
By removing the screws 19 shown in Fig. 2, the outer cover 17 can be opened with an inner M16
It can be removed from. When this exterior cover 17 is removed,
As shown in FIG. 14, since the parts are exposed through the opening 16a, the parts can be adjusted or replaced from outside the inner lid 16. Furthermore, since the magnetic head 58 is exposed when the regulating plate 118 is removed from the plate 113, the magnetic head 58 can also be cleaned.

〔Effect of the invention〕

In the present invention having the above configuration, when the jacket holder storing the magnetic sheet jacket moves to the loading position, it first rotates to approach the device main body, and then moves in parallel to enter the device main body. Therefore, the positioning hole formed in the jacket can be inserted straight over the positioning pin protruding from the main body of the device. Therefore, in the conventional device in which the jacket is rotated and fitted into the positioning pin, the positioning hole expands, but in the present invention, the jacket is moved in parallel, so this problem does not occur.
