Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium ejecting device for an information recording / reproducing device equipped with, for example, an electronic still camera.

[0002]

2. Description of the Related Art An information recording / reproducing apparatus of this type has a loading portion into which a plate-shaped recording medium such as a memory card is loaded in a sliding manner. A plurality of connector pins are respectively inserted into a plurality of concave contact points formed at the tip end of the disk, so that information can be recorded / reproduced on / from a recording medium. By the way, as a device for ejecting the recording medium from the loading section, there has been known a device which is interlocked with an operation of an eject button provided in the vicinity of a front end opening of the loading section. That is, when the eject button is pressed while the plate-shaped recording medium is loaded in the loading section, a predetermined take-out member pushes the tip of the recording medium in the ejecting direction in conjunction with this and ejects the recording medium from the connector pin. At the same time as separating, one end of the recording medium is projected from the loading section. In this state, the recording medium can be pulled out from the loading portion by holding the protruding portion.

However, in this conventional apparatus, since a lid member for opening and closing the opening of the loading section is not provided, it is highly likely that dust or water droplets enter the loading section to cause defective recording / reproduction. Further, when the recording medium is ejected, sliding frictional resistance acts between the concave contact and the connector pin, so that the eject button cannot be separated unless the eject button is pressed quite strongly, and there is a problem in operability.

Therefore, Japanese Patent Laid-Open No. 2-54388 discloses an apparatus in which a lid member for opening and closing the opening of the loading portion is provided, and this lid member also functions as an eject knob for taking out a recording medium. There is. That is, in this apparatus, the lever mechanism is rotated by rotating the lid member with the plate recording medium loaded to open the loading portion opening, and then further pulling out the lid member in the take-out direction or pushing it in the loading direction. The recording medium is detached from the connector and ejected. Since the lever principle can be utilized by providing the lever mechanism, the recording medium can be ejected with a relatively small operating force even if there is sliding friction resistance between the concave contact and the connector pin.

[0005]

However, in this apparatus, since the eject knob is linearly operated at the time of ejecting the recording medium, although the lever mechanism is provided, the operating force at the time of ejecting the recording medium can be considerably reduced. I can't. Also, when pulling or pushing in the eject knob, the device body (for example, the electronic still camera body) may move in the operating direction, and in order to prevent this, the device body must be held by the other hand. , It is not easy to use.

An object of the present invention is to prevent the entry of water and dust into the recording medium loading section, and at the same time, to reduce the operating force for taking out the recording medium and improve the usability of the recording medium reproducing apparatus. To provide.

According to the fifth aspect, the pressing portion 28 of the lid member 30 is made of an elastic body. According to a sixth aspect of the present invention, the holding section 3a that holds a part of the recording medium 30 and moves integrally with the recording medium is provided in the loading section 1A. A seventh aspect of the present invention further includes a regulation unit 1b that regulates rotation of the interlocking lever mechanisms 6 and 12 when the lid member 14 rotates in the opening direction at a predetermined position.

[0008]

When the lid member 14 is opened from the closed position, the interlocking lever mechanisms 6 and 12 interlock with this to drive the recording medium 30 loaded in the loading portion 1A to the unloadable position. Since the lid member 30 is rotatably operated, the lid member itself constitutes a lever mechanism, and the lid member 14 and the interlocking lever mechanisms 6 and 12 can constitute a double lever. The operation force during discharging can be further reduced. Further, since the lid member 14 is pivotally opened and closed, the apparatus main body 1 does not move due to the opening operation of the lid member 14 when the recording medium is ejected on a desk or the like, and the other hand is used. Need not hold.

Incidentally, in the section of means and action for solving the above-mentioned problems for explaining the constitution of the present invention, the drawings of the embodiments are used to make the present invention easy to understand. It is not limited to.

The connector pins 2a are inserted into the plurality of concave contact points 30A (FIG. 2) provided in a, whereby information recording and reproduction on the memory card 30 is permitted.

Reference numeral 3 denotes a plate-shaped slide member that can move in the loading section 1A in the insertion / removal direction of the memory card 30. When the memory card 30 is not inserted, the slide member 3 is at the position shown in FIG. is there. Reference numerals 4 and 5 are guide members for guiding the movement of the slide member 3. On the upper surface of the end portion of the slide member 3 on the connector 2 side, a pair of holding portions 3a that are bent toward the opening 1a are provided, and as shown in FIG. 2, the tip of the memory card 30 is held by the holding portions 3a. On the other hand, a bent portion 3b bent downward is formed at the end of the slide member 3 on the opening 1a side, and the arm of the torsion spring 26 is engaged with the bent portion 3b. Therefore, the slide member 3 is always biased toward the opening 1a by the biasing force of the torsion spring 26. Further, at the position shown in FIG. 5, the bent portion 3b abuts the stopper 25 projecting from the opening 1a, thereby preventing the slide member 3 from falling off.

Further, a fan-shaped lead-in portion 3d is formed at the end of the slide member 3 on the opening 1a side, and a bent portion 3e bent upward as shown in FIG. 6 is formed at the right end of the figure. When the memory card 30 is not loaded, the introducing portion 3d projects outward from the opening 1a as shown in FIG. 5, and one end of the memory card 30 is placed on the upper surface of the introducing portion 3d and the side surface of the bent portion 3e. By applying, the memory card 30 is positioned and accurately guided in the loading section. Further, a claw 3c is formed on the wall surface of the hole HL formed in the slide member 3 as shown in FIG. 3, and the claw 3c engages with a ratchet member 8 described later.

Reference numeral 6 denotes a shaft 6 below the slide member 3.
The lever 6 is rotatable around c, and the pressing portion 6a formed on the lever 6 is brought into contact with the bent portion 3b of the slide member 3. Further, a gear portion 6d is provided on one end side of the lever 6, and the gear portion 6d is meshed with a gear 31a of a damper 31 fixed to the housing 1. Therefore, the lever 6 rotates slowly and smoothly while rotating the gear 31a. Reference numeral 1b is a guide pin that is engaged with the guide groove 6d of the lever 6 and guides the rotation of the lever 6.

Further, in the vicinity of the rotation shaft 6c of the lever 6, a ratchet limiting portion 6b for limiting the rotation of the ratchet member 8 is provided.
Is provided. The ratchet member 8 is rotatably supported on the housing 1 by a tension spring 10 in a counterclockwise direction (see FIGS. 10A to 10C) or a clockwise direction (FIG. 1).
0 (see (d)). The arm portion protruding from the ratchet member 8 has a bent portion 8 as shown in FIG.
The claw 3c of the slide member 3 is engaged with the bent portion 8a in the state where a is formed and the rotation of the ratchet member 8 is blocked, so that the movement of the slide member 3 in the loading direction is blocked.

On the other hand, one end of the lever 12 is rotatably connected to the other end of the lever 6 about a shaft 13 as shown in FIG. 4, and the other end of the lever 12 supports the lid member 14 for rotation. It is rotatably connected to the portion 15. The lid member 14 is the shaft 1
4a is rotatable between an open position shown in FIG. 1 and a closed position shown in FIG. 8, and is constantly biased in the opening direction by a torsion spring 17. When the lid member 14 is in the closed position, the loading portion opening 1a is covered by the lid member 14 and the key portion 18 provided at the tip of the lid member 14 is provided.
Is engaged with the key portion 19 on the side of the housing 1 to prevent the lid member 14 from being opened.

The key portion 19 is projectingly provided on one end side of a lever 41 rotatably provided on the housing 1.
1 is always biased counterclockwise by a torsion spring 42. The tip of the eject button 22 is engaged with the other end of the lever 41, and when the eject button 22 is pressed,
The lever 41 rotates clockwise against the biasing force of the spring 42, and the engagement between the key portion 19 and the key portion 18 is released. On the other hand, the lid member 14 is provided with a pressing spring 28 that presses the memory card 30 in the loading direction when the lid member 14 is closed. Although not shown, in the loading section 1A,
The memory card 30 is upside down with respect to the proper loading posture,
Alternatively, a device is provided to prevent loading when the front-back direction is reversed.

Next, the operation of the embodiment will be described. (1) Operation when loading memory card: When loading the memory card 30 into the loading section 1A, as shown in FIG.
With one side of the memory card 30 open, the one end side of the memory card 30 is applied to the introduction part 3d and the bent part 3e of the slide member 3 and pushed in the loading direction. As a result, the tip portion 30a of the memory card 30 is held by the pair of holding portions 3a of the slide member 3, and thereafter, the memory card 30 and the slide member 3 move integrally against the biasing force of the torsion spring 26.

When the slide member 3 moves to the position shown in FIG. 1, the claw 3c engages with the bent portion 8a of the ratchet member 8,
As a result, the ratchet member 8 rotates in the clockwise direction against the biasing force of the spring 10. However, the ratchet member 8
As shown in FIG. 10 (a), a part of the contact portion abuts against the ratchet limiting portion 6 b of the lever 6 and further rotation is blocked, so that the loading direction of the slide member 3 via the ratchet member 8 and the lever 6 is prevented. Is prevented from moving, and the memory card 30 sandwiched by the slide member 3 cannot be inserted any more. On the other hand, when the hand is released from the memory card 30 in this state, the ratchet member 8 is rotated in the counterclockwise direction by the urging force of the spring 10, but the bent portion 8a and the claw 3c are engaged with each other, as shown in FIG. Stop at position. Therefore, at this time, the memory card 30 is held in a state where a part thereof is exposed from the opening 1a.

When the lid member 14 is rotated in the closing direction in this state, the lever 6 rotates in the counterclockwise direction in the drawing while rotating the gear 31a of the damper 31 via the lever 12.
As shown in FIG. 10C, the ratchet limiting portion 6b of the lever 6
Retracts from the ratchet member 8. Therefore, the ratchet member 8 is allowed to rotate clockwise, and the slide member 3 is allowed to move in the loading direction. When the lid member 14 rotates to the position shown in FIG. 7, the pressing spring 28 contacts the end portion 30b of the memory card 30 and presses it in the loading direction,
The slide member 3 moves in the loading direction against the urging force of the torsion spring 26 while rotating the ratchet member 8 in the clockwise direction. Therefore, when the memory card 30 also moves in the loading direction integrally, the connector pin 2a is inserted into the concave contact 30A, and the lid member 14 is completely closed, or immediately before that, the memory card 30 is brought to the full loading position shown in FIG. Reach

Immediately before the lid member 14 is completely closed, the tip end of the key portion 18 abuts on the key portion 19 and is rotated clockwise, and when the lid member 14 is completely closed, the key portion 19 is attached with the spring 42. The lid member 14 is prevented from being opened by being engaged with the key portion 18 by the force. In this state, it becomes possible to record information in the memory card 30 and reproduce the information recorded in the memory card 30 via the connector 2.

Here, even if the loading position of the memory card 30 is slightly different due to the variation of the mounting position for mounting the connector 2 on the housing 1, the difference can be absorbed by the pressing spring 28, and the lid member 30 is completely closed. There is no inconvenience of disappearing. Further, since the lid member 14 prevents water droplets and dust from entering the loading portion, the occurrence of read / write defects can be suppressed to a minimum. further,
When the lid member 14 is in the open position, the ratchet member 8
This prevents the slide member 3, that is, the memory card 30, from moving to the loading position. Therefore, even if the memory card 30 is pressed in the loading direction with the lid member 14 left open, the lid member 14 cannot be opened via the lever 6. It is not closed as desired, and there is no inconvenience such as pinching a finger between the lid member 14 and the housing 1.

(2) Operation when taking out the memory card: When the eject button 22 is pushed to take out the loaded memory card 30, the lever 41 rotates clockwise against the urging force of the spring 42, The engagement of the key portions 18 and 19 is released. Along with this, the lid member 14 is rotated in the opening direction by the urging force of the spring 17, and the pressing spring 28 of the lid member 14 is retracted from the end portion 30b of the memory card 30. Further, the rotation of the lid member 14 causes the lever 6 to rotate in the clockwise direction via the lever 12, and the pressing portion 6a of the lever 6 contacts the bending portion 3b of the slide member 3 as shown in FIG. Therefore, the slide member 3 includes the lid member 14 and the lever 1.
A biasing force by the spring 17 in the ejection direction acts via the Nos. 2 and 6, and a biasing force in the same direction by the spring 26 acts, but a sliding friction resistance between the connector pin 2a and the concave contact 30A of the memory card 30. Are both torsion springs 26, 17
Since it is larger than the total urging force of the memory card 30, the memory card 30 is kept in the loaded state at this point, and the lid member 14 also stops at the position shown in FIG.

In this state, when a finger is put on the tip of the lid member 14 to rotate it in the opening direction, the lever 6 rotates clockwise through the lever 12 and the pressing portion 6a of the lever 6 slides. Since the bent portion 3b of 3 is pressed in the ejection direction, the slide member 3 and the memory card 30 move integrally in the ejection direction, and the concave contact 30A separates from the connector pin 2a. In addition, when the slide member 3 is moved, as shown in FIG.
When the pawl portion 3c rotates the ratchet member 8 in the counterclockwise direction as shown in (d) and the pawl portion 3c moves away from the bent portion 8a of the ratchet member 8, the ratchet member 8 is in the initial state by the biasing force of the spring 10. Return to. Since the sliding friction resistance between the concave contact 30A and the connector pin 2a is released, the sliding member 3 is automatically moved by the urging force of the spring 26 without operating the lid member 14 thereafter. Driven to the position and by the biasing force of the spring 17, the lever 6
The lid member 14 is driven to the open position via the. And
By driving the slide member 3, the memory card 30 is driven to a position where it can be taken out (a position where the end 3b is exposed from the opening 1a), and in this state, the memory card 30 can be taken out by manually pulling the end 30b. it can.

Here, since the lid member 14 itself constitutes a lever mechanism, the lid member 14 and the lever 6 are
By this, a double lever mechanism is configured, and therefore, the rotational operation force of the lid member 14 can be greatly amplified and converted into a force in the ejection direction of the slide member 3, that is, the memory card 30. Therefore, as described above, the lid member 14
By turning a finger on the tip of the memory card 30 to rotate it, even if a sliding frictional resistance occurs between the concave contact 30A and the connector pin 2a, the memory card 30 can be driven to a position where it can be taken out with a small operating force. . Also, memory card 3
Since 0 is sandwiched by the sandwiching portion 3a of the slide member 3, the memory card 30 does not undesirably jump out of the loading portion 1A and drop during ejection. Since the holding portion 3a is formed by bending the tip of the slide member 3, it is not necessary to provide a new holding portion, and the number of parts and cost can be reduced. Further, the damper 3
Since the lid member 14 opens slowly and smoothly by the action of the first gear 31a, the operator does not feel uncomfortable due to the sudden opening operation of the lid member 14. Furthermore, FIG.
When the lid member 14 is in the open position as shown in FIG. 3, the introduction portion 3d of the slide member 3 is positioned within the triangle S having the tip end, the base end portion of the lid member 14 and the left end tip of the housing 1 as vertices. Therefore, the introduction portion 3d is less likely to hit an external object and is less likely to be damaged.

If the lid member 14 is closed from the state shown in FIG. 5 without setting the memory card 30, the lid member 1
The back surface of the slide member 3 immediately before the slide member 3 is completely closed.
The slide member 3 is slightly driven in the loading direction by coming into contact with the leading end of the introducing portion 3d. Thus, even when the memory card is not loaded, by closing the lid member 14, the loading section 1A
Water droplets and dust are prevented from entering. Further, when the eject button 22 is operated in this state, the lid member 14 is suddenly opened to the open position by the biasing force of the spring 17, and the spring 2
The urging force of 6 moves the slide member to the position shown in FIG. Also at this time, the lid member 14 is opened slowly due to the engagement of the gear 31a and the gear portion 6d, so that the operator does not feel uncomfortable.

In the structure of the above embodiment, the memory card serves as the plate recording medium, the levers 6 and 12 serve as the interlocking lever mechanism, the ratchet member 8 and the claw 3c of the sliding member serve as the loading preventing means, and the guide pin 1b serves as the regulating means. Respectively.

Although the pressing spring 28 presses the memory card 30 in the loading direction by the closing operation of the lid member 14, the loading of the memory card 30 is performed independently of the closing operation of the lid member 14. It may be configured as follows. Also, although the lever mechanism is composed of two levers 6 and 12,
You may comprise with one lever. Further, for example, an engaging portion that engages with the front end surface 30a of the memory card 30 is provided at the tip of the lever mechanism, and the engaging mechanism is driven in the ejection direction by the lever mechanism in conjunction with the opening operation of the lid member 14. Alternatively, the memory card 30 may be ejected to a removable position.

[0028]

According to the present invention, the recording medium loaded in the loading section is driven to the unloadable position in conjunction with the opening operation of the lid member in the closed position.
A double lever can be configured by the lid member and the interlocking lever mechanism, and the operation force at the time of ejecting the recording medium can be further reduced as compared with the conventional case. Particularly in a device of a type in which a connector pin is inserted into a concave contact of a loaded recording medium, the recording medium can be ejected with a smaller operating force even if sliding friction resistance occurs between the concave contact and the connector pin. it can. Further, since the lid member is pivotally opened and closed, the apparatus body does not move due to the opening operation of the lid member when the recording medium is ejected on a desk or the like, and thus the other body holds the apparatus body. The discharge operation can be performed without the need, and the usability can be improved. According to the third aspect of the present invention, since the cover member is provided with the pressing portion that presses and drives the recording medium to the loading position with the closing operation of the lid member, the recording medium is loaded with the closing operation of the lid member. And the operability at the time of loading is improved. Further, according to the invention of claim 4, when the lid member is in the open position, the movement of the recording medium to the loading position is blocked, and the movement of the recording medium to the loading position is allowed in accordance with the closing operation of the lid member. Therefore, even if the recording medium is pressed in the loading direction with the lid member open, the lid member does not undesirably close via the lever mechanism, and a finger is caught between the lid member and the apparatus main body. There is no inconvenience. Further, according to the invention of claim 5, since the pressing portion of the lid member is made of the elastic body, even if the loading position of the recording medium is slightly different due to the variation of the mounting position for mounting the connector on the information recording / reproducing apparatus main body. The difference can be absorbed by the pressing member, and there is no inconvenience such as the lid member not being completely closed. Further, according to the invention of claim 6, since the holding portion for holding a part of the recording medium in the loading portion and moving integrally with the recording medium is provided, the recording medium pops out undesirably and drops when the recording medium is ejected. There is no such thing. Further, according to the invention of claim 7, the rotation of the interlocking lever mechanism when the cover member is rotated in the opening direction is restricted by the restricting means at a predetermined position, so that the cover member at the open position is further opened. Even if a directional force is applied, an unreasonable force is not applied to the rotating shaft portion of the lid member, and damage to the lid member can be prevented.
