Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device for an electronic still camera that records video signals and the like on a magnetic sheet.

2. Description of the Related Art As a recording device for an electronic still camera, its compactness is first of all required. In order to achieve this compactness, simplification of components and miniaturization of parts have been attempted. Especially, the moving mechanism that moves the head in the radial direction of the seat occupies a large volume and is strongly compact and simple. Is being pursued. For example, like a normal floppy disk drive, a mechanism that changes the rotational force of a stepping motor into a linear motion of the head with a precision screw or steel belt is certainly convenient for high-speed reciprocating motion of the head, but the motor and its The drive circuit, conversion mechanism, etc. are inevitably large, which makes them unsuitable for mechanisms for incorporating cameras. Therefore, in positioning a camera, which is a device mainly for recording, a method of limiting the movement of the head to a single direction and returning the head to the initial position every time the sheet is changed has been proposed and has been established. That is, for example, the head is always urged in one direction, the solenoid moves the head against the urging force, and the ratchet mechanism holds the position. Then, there is a method in which when the seat is changed, the engagement of the ratchet mechanism is released by a mounting member and the head is returned to the initial position by the urging force. (In addition, the biasing direction of the head itself is different from the above,
There is also a method in which the head is returned to the initial position by another charged spring force, which is the same as the moving direction. ) Problems to be Solved by the Invention However, in the above method, since the head is returned to the initial position by the spring bias, the biasing force inevitably becomes a load on the moving mechanism. Further, when the head returns to the initial position, an impact is applied to the head, which is disadvantageous for positioning the head which requires high accuracy. This head positioning requires accuracy in the radial direction positioning of the seat by the above-mentioned cam, but it has a very high accuracy such as head height and tilt that greatly affect the head touch with the seat. The required points must be achieved. Therefore, this shock must be avoided. Therefore, it is conceivable to provide a damper, but this is not desirable for this type of device that pursues the smallest possible size and weight and the simplification of the mechanism described above, and a solution has been longed for.

Means for Solving the Problems The present invention relates to a magnetic head for recording a signal on a magnetic sheet, a magnetic head holding member for mounting the magnetic head, a magnetic head holding member, and a magnetic head holding member in contact with the magnetic head holding member. A cam for positioning the magnetic head, an elastic member for urging the magnetic head holding member in a direction of abutting the cam, a ratchet integrally formed with the cam, and a claw engaging with the ratchet. And a mounting member for holding the magnetic sheet, and an eject lever. First and second strokes continuous with the eject lever are provided, and the movement of the eject lever is held within the first stroke by holding the magnetic head. A second connecting member that transfers the magnetic head to an initial position against the biasing force of the elastic member. A recording device for an electronic still camera, comprising a release member for transmitting the movement of the eject lever to the mounting member within a stroke and discharging the magnetic sheet to the outside of the device.

Action The present invention has the above-described configuration, which directly returns the head to the initial position by the ejecting force that is always required when the sheet is discharged to the outside of the main body, so that there is no need for spring bias and an increase in load. It is possible to avoid impact on the head. In addition, the mechanism does not need to be complicated because the force of the eject operation by human hands (but not always) is used. This is because the force of the eject operation is due to the force outside this device, and the device itself can be pursued to be as simple as possible.

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

1A and 1B are configuration diagrams of a recording apparatus according to the present invention. The cassette 1 uses the shutter 2 to insert a head (described later).
The shutter 2 is movable in the direction of arrow 3. Therefore, by sliding the cassette 1 in the direction of the arrow 4 and inserting it into the compartment 5, the shutter opening / closing mechanism 6 opens the shutter 2. The compartment 5 and the garage 8 correspond to a mounting member that holds the magnetic sheet described in the claims. When the cassette 1 is ejected from the compartment 5, the shutter opening / closing mechanism 6 automatically closes the shutter 2. The compartment 5 includes a plurality of guide pieces 7a to 7f on the side where the cassette 1 is inserted,
It is easy to insert. The garage 8 is arranged outside the compartment 5, and both are rotatably supported by the support shafts 10a and 10b on the base plate. The axial support direction is the insertion direction of the cassette 1, that is, the direction of arrow 4. Therefore, when inserting the cassette 1, the cassette 1 is slid with respect to the base plate 9. However, the sliding direction is parallel to the base plate 9, and there is no problem in interlocking with the slide plate A11. The slide plate B12 is on the slide plate A11, and both slide on the base plate 9 in the cassette insertion direction to move the head 13 and eject the cassette 1. The two plates are attracted to each other by a spring 14. The bent portion 11a of the slide plate A11 is the cassette 1
When it is inserted, it moves in the direction of arrow 15 to charge the slider 16, and the solenoid 17 attracts
The head 13 is moved by operating a stepped claw (described later). When the garage 8 is opened (the state is as shown in the figure, but the figure is wider than it is for the sake of illustration), the opening spring 18 moves the hook plate 19 into engagement with its protrusion 19a. , The hook portion 11b of the slide plate A11 is disengaged, and the slide plate A11 advances in the direction opposite to the arrow 15 by the force of a spring (described later) charged by the insertion of the cassette 1. By this movement, the bent portion 11a ejects the cassette 1 out of the compartment 5. Also slide plate A1
1 pushes the slide plate B12 at the same time to move the rack plate 12a of the slide plate B12 and the gear plate.
Motion is transmitted to the ratchet 23 via gears 21 and 22 provided on the 20 to return an integrally provided cam (described later) to the initial position. The details will be described later with reference to FIG. 8 and FIG. 12, so the head plate 98 arranged on the back side of the base plate 9 is arrowed by an external force although not shown here.
By moving in the direction 99, this movement
The cam follower 24 away from the cam and the head 13
To the initial position. The slider 16 corresponds to the magnetic head holding member described in the claims. Slider 16 presses against slide block 25 with springs 26a to 26c (26d
Moves along slide shafts 27a and 27b held by adjusting screws (described later) and is spring-biased to the cam side. Therefore, when no force in the direction of arrow 99 is applied to the head plate 98, the head plate 98 contacts the cam.

In the garage 8, the spring 28 is the spring hook portion 29 of the base plate 9.
The springs 31 and the garage springs 30 keep them open all the time, and the springs 31 make the compartment 5
Is urged away from the garage 8. Now insert the cassette 1 into the compartment 5 and insert the garage 8
If you close the compartment, the height of the compartment 5 is determined by the pin 32.
The cassette 1 until it comes into contact with the positioning hole 33
The a and 33b are fitted and positioned by the positioning pins 34a and 34b, and the height is determined by the two pins and the height determining pin 35. During this time, the switch 37 that engages with the erroneous erasure prevention claw 36 of the cassette 1 is pushed to the position where it does not engage with the cassette 1 by the protrusion 38 of the garage 8. After this,
When the garage 8 descends, the presser springs 39 hold the cassette 1 and the insertion springs 40 rotate the spindle 42 of the motor 41.
Push the center core (described later) into. Also, pad spring
The pad plate 44 held in the garage 8 by 43
Although the PG45 and the pad 46 are provided, the pad height determining pins 47a and 47b also come into contact with the pad 46, and the height adjusting screw 48 also comes into contact with the central portion (described later) of the spindle 42 for positioning. To be done. After completion of these operations, the lock hole 49 of the garage 8 is engaged with the lock 50 to fix the garage 8. To release, the pressing portion 50a is pushed against the spring 51 so that the lock 50 is disengaged.

In this way, the cassette 1 is fixed on the base plate 9 and recording is performed by the head 13. The operation of each part will be described in more detail with reference to the drawings.

FIG. 2 is an explanatory view of the cassette 1 used. The built-in magnetic sheet 52 is attached to the center core 53.
The center core 53 is provided with positioning walls 54a, 54b, a positioning spring 55, and a PG yoke 56, and is positioned with respect to the spindle 42. As described above, the housing 57 has the positioning holes 33a and 33b, the positioning pins 34a and 34b, and the height determining pin 3
Positioned by 5. Reference numeral 58 is a window provided in the same shape on both sides of the casing 57 for exposing the magnetic sheet 52 after the shutter 2 slides in the direction of the arrow 2 ', and the pad height determining pins 47a, 47b are also in this window. Use inside 58. Reference numeral 59 is a label that allows the user to write down the date of use and organize it. 36 erasure prevention claws are provided on the back side,
Used to prevent accidental erasure of recorded contents or overwriting.

FIG. 3 shows the structure on the base plate 9. Fourth
FIG. 8 to FIG. 8 are explanatory views of each component, and the description will be given using the above drawings. 4 is a view from the X direction of FIG. 3, FIG. 5 is from the Y direction, and FIGS. 7A and 7B are from the Z direction. Nata Fig. 8 shows the back side. slide plate
A11 moves in the direction of arrow 15 against the spring 60 by the cassette 1 and is charged by the hook plate 19 (Fig. 4).
11 '). When the garage 8 descends, the hook plate 19 does not move because the open spring 18 bends, but when it rises, the hook plate 19 moves against the spring 61 due to its shape and the hook portion 19 moves.
11b is disengaged and slide plate A11 shows arrow 15
And move in the opposite direction. The slide plate B12 is attracted to the slide plate A11 by the spring 14 and finally comes into contact with the slide plate A11 to lose its spring force and move integrally with the force of the spring 60. This movement is performed by the rack section as described above.
The gear 62 provided integrally with the ratchet 23 via the gear 12a and the gears 21 and 22 is rotated, and the cam 63 is also rotated. The cam 63 positions the magnetic head 13. Sixth
FIG. A shows the state at this time, and the pointer 64 is engaged with the ratchet 23, but the ratchet 23 is indicated by the arrow with respect to the shaft 65.
Since it rotates in 66 directions, it moves like 64 'and ratchet
23 rotations are possible. 67 is a counter lever, the axis
68 is shared with the pointer 64, its end portion 67a is pulled by a spring 69 and is urged clockwise, and the other end portion 67b is in contact with the stopper portion 70 of the base plate 9. The pointer 64 and the counter lever 67 serve as a claw that engages with the ratchet 23 described in the claims. This counter lever
67 is configured to sandwich the pointer 64 from above and below,
A spring 71 is provided to bias the pointer 64. The projection 64a of the pointer 64 has a gap d between itself and the end 67a because the claw 64b is in contact with the ratchet 23 and is stopped. Since these spring forces are small, the slide plate A11
It doesn't put too much load on the movement. That is, especially the nail part
The cam 63 can be easily moved to the initial position without requiring a mechanism for separating the 64a from the ratchet 23. The head 13 is screwed to the slider 16. The movement of the slide plate A11, which is moved by the force of the spring 60, is stopped at a predetermined position by the stopper 74 and the state is maintained. At this time, the ratchet 23 has the claw portion 64 of the pointer 64.
The cam 63 rotates to a position where the cam 63 gives the head 13 a first track position when it engages with the tooth portion 23a. However, there is a backlash in the meshing portion of the gear train, and the inertial force of the ratchet 23 or the like may cause the tooth portion 23a to overrun, leading to a state in which the cam 63 is provided with a correct position. Therefore, the ratchet 23 is provided with a stopper pin 96, and the base plate 9 is also provided with a stopper pin 97. These two stopper pins 96 and 97 are provided with a clearance d when the slide plate A11 comes into contact with the stopper 74 and stops.
It is arranged so as to produce. This clearance d is long enough not to advance to the next tooth even if the ratchet 23 overruns. That is, the overrun due to the looseness of the gear train is surely prevented. But the whole spring
The impact from 60 has already been received by the stopper 74, and in particular, the impact force is not transmitted to these stopper pins 96 and 97, and only overrun is prevented. In other words, the force for surely moving the cam 63 to the initial position is received by the other parts, and the ratchet 23 receives only the excessive force so that the accurate positional relationship is not broken. Is taken into consideration.

By thus opening the garage 8, the cassette 1 is ejected and the cam 63 is returned to the initial position. At this time,
As shown in FIG. 8, the head plate 98 moves in the direction of arrow 99 prior to the movement of the slide plate B12. This movement is directly obtained from the eject lever, which will be described later. The slider 16 penetrates the slide block 25 and the base plate 9 and is located on the back side of the base plate 9 at the head plate.
A head pin 100 that engages with the convex portion 98a of 98 is provided. The convex portion 98a of the head plate 98 usually has a clearance e ₁ between the convex portion 98a and the position where the head 13 provides the innermost circumference, and does not hinder the movement of the head 13. However, the stroke S given by the eject lever
_The head plate 98 having the clearance e ₁ is engaged with the head pin 100 to move the head 13 to the outermost position (cam 6).
When 3 takes the initial position = the first track position, the cam follower 24 and the cam 63 come into contact with each other to move to the position 100 ') that determines the position of the head 13 The position 100 moved e ₂ more than the stroke S ₂ It is set to move up to ″ (98 ′). That is, in this state, the cam 63 and the cam follower 24 do not come into contact with each other, and when the cam 63 moves to the initial position as described above, It does not create a load on 63 and does not force the spring 60 to an unnecessarily large force.
Since the movement of 63 etc. is not transmitted, there is no shock and the cam 63
The outer periphery and the cam follower 24 are not damaged. Therefore, it is extremely effective as a moving mechanism of the head 13 that requires precise positioning (height, inclination, track position). Of course, the eject lever is constructed so that the garage 8 is opened after the head plate 98 is moved.

Now, when a new cassette 1 is inserted in this state, the fourth
As shown in the figure, the insertion direction becomes parallel to the base plate 9, and the slide plate A11 moves in the arrow direction to
It reaches 1'and stops. But slide plate B12
As shown in FIG. 6A, since the pointer 64 and the ratchet 23 are engaged and cannot move, the spring 14 is stretched and the slide plate B12 is biased in the direction of the slide plate A11, that is, in the direction of arrow 15. As described above, this force exists until the garage 8 is opened and the slide plates A11 and B12 come into contact with each other, and is a force in the direction of arrow 75 in FIG. 6B. Therefore, the ratchet 23 becomes stable in the state shown in FIG. 6A. At the same time when the garage 8 is closed, the head plate 98 also returns to its original position and the head pin 100 becomes free, so that the slider 16 is in contact with the cam 63 by the spring 95 and is stable, and the position of the head 13 is determined. This spring 95
Corresponds to the elastic member described in the claims.
This charging force resists the springs 14 and 60, but the spring 14 can rotate the ratchet 23 against the contact frictional force between the cam 63 and the cam follower 24 by the spring 76,
The spring 60 requires a frictional force between the pointer 64 and the ratchet and a force with which the slide plate A11 can move while ejecting the cassette 1. Therefore, although a little large force is applied, since it is performed by the insertion operation of the cassette 1, that is, the operation by the human hand, or the force obtained from the mechanism outside the device, it does not burden the device at all and simplifies it. Does not interfere with miniaturization. Moreover, the spring 14
Does not affect the spring 60 only by exerting a force to draw the two plates, and the head 13 is moved by the head plate 98 as described above when the cassette 1 is ejected. There is no load because it exists. That is, the charging force is not increased unnecessarily, and the discomfort to the hand when the cassette is inserted and the burden on other mechanisms are small. Further, by making the axial support direction of the garage 8 and the compartment 5 the same as the sliding direction of the cassette 1, this cassette insertion force can be easily used for the sliding force on the base plate 9, and no conversion mechanism is required. .

Under these circumstances, the solenoid 17 is energized. The solenoid shaft 76 is attracted as shown in FIG.
Move in the 77 direction. Therefore, the counter lever 67 is rotated counterclockwise against the spring 69 via the pin 78. edge
67a abuts the protrusion 64a of the pointer 64,
Rotate 64. At this time, the claw portion 67b of the counter lever 67
Moves to a position where it engages with the ratchet 23, and then the claw portion 64b of the pointer 64 separates from the ratchet. Since the ratchet 23 has a biasing force in the direction of arrow 75 as described above,
It rotates until it comes into contact with the claw portion 67b. This rotation amount is the claw 64b
Is set to cross the ratchet 23 by a mountain. After that, the power to the solenoid 17 is cut off, and the spring 69
Return to the state of FIG. 6A again. At this time, the ratchet 23 is moving a mountain, and the cam 63 causes the slider 16 to move.
Moves. In this way, the head 13 is moved one track at a time when the solenoid 17 is energized once. The attraction force of the solenoid 17 only needs to resist the friction force between the ratchet 23 and the pointer 64 due to the biasing force in the direction of the arrow 75 and the spring 69.
It is very useful for downsizing and power saving. Also, energization is ON-OF
The circuit configuration is simple because only F is required. This head 13
Is moved in the direction opposite to the arrow 73 in FIG.
Moves up to 13 '. Further, since the pointer 64 and the counter lever 67 have a two-stage configuration, when the head 13 is positioned, that is, the ratchet 23 is positioned, a gap d is provided between the counter lever 67 and the pointer 64, and the counter lever is provided.
It is possible to keep the accuracy of 67 without affecting it. Also, when returning the cam 63 to the initial position,
Move the pointer 64 independently and move the cam 63 to move the head 13
When sending, it is moved as a unit to prevent the mechanism from becoming complicated.

The head 13 is fixed to the slider 16, and the two slide shafts 27a, 27 which are guide members of the slider 16 are provided.
b is constructed as shown in FIG. 7B. The slide shaft 27a is inserted into the engagement hole 16a of the slider 16. 79 is a bush. The slide shaft 27b is fitted in the engagement groove 16b, and the slide shaft 27a determines up and down and left and right by 27b. Therefore, the slide shaft 27a is attached to the slide block 25 by the two adjusting screws 8a as shown in the figure.
It is held by 0 and 81 and the presser spring 26b, and its vertical and horizontal positions can be adjusted. (Although not shown, the other end has the same structure.) The slide shaft 27b is held by the adjusting screw 82 and the pressing spring 26c, and its vertical position can be adjusted. (The other end has the same structure). In this way, the position of the head 13 can be completely adjusted over the entire stroke, such as delicate up / down, left / right, and tilt with respect to the motor 41.
It is very effective in contact with the magnetic sheet 52 and maintaining track accuracy. Further, the positional relationship between the cam 63 and the slider 16 can be adjusted by the adjusting plate 72, and the position of the head 13 can obtain sufficiently high performance without requiring high precision other than the cam 63 and the ratchet 23. it can.

On the other hand, the structure of the garage 8 and the like will be described with reference to FIGS. 9A, 9B and 10. These are the views seen from the Y direction in FIG.

In FIG. 9, A is an open state and B is a motor for the cassette 1.
It is set to 41. As shown in FIG. 5, the two positioning pins 34a, 34b for positioning the cassette 1 are located far from the rotation axis of the garage 8 and the compartment 5, which connects the support shafts 10a, 10b, and is used for attaching and detaching the cassette 1. It is the motor 41, the pad 46, etc. that have an effect. As shown in FIG. 8A, according to the present embodiment, these members are also used in the cassette 1 depending on the axial direction of the garage 8 and the position of the pad 46 entering the window 58 of the cassette 1. It is configured so that it can escape with the opening angle reduced. That is, when the cassette 1 is detached, the opening angle thereof is minimized to prevent intrusion of dust and the like and contact with the inside by fingers and the like. The opening angle of the garage 8 is determined by the contact with the member having the support shaft 10b, and the opening angle of the compartment 5 with respect to the garage 8 is determined by the protrusion 83 of the compartment 5. Now 9th
In the movement from FIG. A to FIG. 9B, the insertion spring 40
Then you can install and remove the cassette 1 and the compartment 5
It is located above. When the garage 8 is lowered as it is, the cassette 1 is set to the motor 41 while the relative angle between the garage 8 and the compartment 5 is held by the spring 31. The center core 53 is inserted into the spindle 42, but at that time, there is some resistance, and the insertion may be incomplete. After compartment 5 stops, only the garage 8 continues to descend and the insertion spring
The 40 presses the center core 53 and firmly pushes it into the spindle 42. Further, when the garage 8 is rotated downward, the upper protruding piece 84 of the compartment 5 and the insertion spring 40 come into contact with each other. Therefore, the tip 40a is separated upward from the center core 53, as shown in FIG. 8B, and does not become a load for rotating the center core 53. In this way, the insertion spring 40 provided in the garage 8 has a simple structure of one leaf spring, but it is possible to reliably insert the center core 53 into the spindle 42 and perform the separating operation thereafter, which is valuable. Is.

Similarly, by the pad spring 43 provided in the garage 8,
Pad plate 44 biased to the base plate 9 side
As shown in the figure, the height of the PG 45 and the pad 46 arranged in the same are precisely determined by the pad height determining pins 47a and the like.

FIG. 10 shows a state in which the position of the pad plate 44 is fixed. The pad 46 has two pad height determining pins 47a and 47b.
The height is decided by abutting against. On the pad plate 44, a height adjusting screw 48 is spring-loaded at a position corresponding to the central portion 85 of the motor 41.
It is equipped with being urged at 86 to absorb backlash. Pad plate 44 with this height adjustment screw 48 as the last one
That is, the height of the pad 46 and PG 45 is accurately determined.
Its plane position is already determined by the pad spring 43.

As a result, the contact between the head 13 and the magnetic sheet 52 and the PG pin
The relationship between the 87 and the PG yoke 56 is also surely guaranteed, and the recording performance can be made sufficient. The PG yoke 56 is provided integrally with a magnetic plate 89 that is attached to the magnetic sheet 52 and is in contact with the pedestal portion 88 of the motor 41. The magnetic plate 89 is attracted to perform positioning and transmission of rotational driving force. The magnetic force of the magnet 90 is transmitted to the PG pin 87. This is detected by the coil 91 and used as the PG output.

Next, the movement of the switch 37 will be described with reference to FIGS.
As described above, when the cassette 1 is attached or detached, all the parts that prevent it are retracted out of the path. However, since the erroneous recording prevention claw 36 is near the axis of the garage 8 and the switch 37 is also near that, it is necessary to move from the normal detectable position. This is seen in Figure 11A. Therefore, as in B, the protrusion 38 of the garage 8 causes the spring 93 to urge the switch plate 92 provided with the switch 37 when the garage 8 is opened.
It is configured so that it does not interfere with the sliding of the cassette 1 in the direction of arrow 15 or the opposite direction. The switch plate 92 is axially supported by a shaft 94 on a side wall portion (not shown) of the base plate 9 and abuts on the base plate 9 to be fixed in position. Then, as described above, it is moved from this state so as not to disturb the slide of the cassette 1. Therefore, it is not necessary to consider the switch 37 in determining the axial support direction of the garage 8, so that the degree of freedom in design is increased, and other advantages can be effectively used.

Finally, the structure of the eject lever will be described with reference to FIG. Move the eject lever 101 in the direction of arrow 102
The engaging lever 104 is pulled by 103 and moves in the same manner. The engagement lever 104 moves the head plate 98 in the direction of arrow 99 to move the head 13. Since there is a gap f ₁ between the engaging portion 104a of the engaging lever 104 and the head plate 98, the stopper 105 is provided at a position advanced by the stroke S ₁ and f _{1 of} the head plate 98. ing. After this, when it further advances by f ₂ against the spring 103, it comes into contact with the tip 106a of the release lever 106 corresponding to the release member described in the claims and rotates in the direction of arrow 107. As a result, the other end 106b pushes the pressing portion 50a of the lock 50 in the direction of the arrow 108 to release the garage 8. Eject lever like this
2 strokes with 101 consecutive movements (ie f ₁ + s
₁ period and f ₂ + α period).
The cam 63 and the cam follower 24 do not come into contact with each other because the garage 8 is released and the garage 8 is released, and thus the load is reduced and the impact is avoided.

EFFECTS OF THE INVENTION As is apparent from the above description, the recording apparatus of the electronic still camera adopting the present invention avoids the spring bias required to return the head to the initial position, and prevents unnecessary impact on the head and the cam. To prevent the head positioning from subtly changing,
It is very advantageous to keep high accuracy. Of course, since no complicated mechanism is required to obtain this effect, it greatly contributes to downsizing of the apparatus as much as possible, and eventually of the electronic still camera body.
