Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a card connection device having a terminal member that can contact a connection terminal of an information storage card and having a loading mechanism for moving the card in the insertion / removal direction.
[0002]
[Prior art]
Conventionally, as this type of card connecting device, the engaging claw of the moving member included in the loading mechanism is engaged with the concave portion formed on the side edge of the card, and the card is moved to the loading completion position or the loading is completed. Some have been moved from the position in the discharge direction.
[0003]
The loading mechanism is driven by a motor. That is, the loading mechanism includes a gear mechanism driven by a motor, a rack that is moved by the gear mechanism, a moving member that is movable in the card insertion / removal direction, and that discharges the card, and one end connected to the rack. And a spring having the other end connected to the moving member.
[0004]
When the card is inserted, the movement of the moving member accompanying the insertion of the card is detected and the motor is driven. By driving the motor, the gear mechanism rotates, whereby the rack moves linearly, and the moving member automatically moves via a spring connected to the rack. During this time, the engaging claw of the moving member engages with the concave portion of the card, and the card and the moving member move integrally to the loading completion position. At the loading completion position, the connection terminal of the card contacts the terminal member. In this state, signals can be transmitted to and received from the card.
[0005]
When the card is ejected, the motor is driven by the ejection operation, and the gear mechanism rotates accordingly. The rotation of the gear mechanism causes the rack to move linearly, and the moving member moves in the direction of the card insertion slot via a spring connected to the rack. During this time, when the moving member moves to a predetermined stroke, the contact between the connection terminal of the card and the terminal member is released. Thereafter, as the rack continues to move, the moving member moves to the discharge position via the spring, and the engaging claw of the moving member separates from the concave portion of the card during the movement. When the card reaches the ejection position, the card can be taken out from the insertion slot.
[0006]
[Problems to be solved by the invention]
In the prior art described above, when the card is held at the loading completion position and the connection terminal and the terminal member are in contact with each other, the connection terminal of the card is pressed by the terminal member. Therefore, if the contact pressure at that time is high, the movement load at the initial stage of card ejection increases, and the card cannot be ejected smoothly. In other words, the spring is temporarily extended by moving only the rack in the initial discharge. Thereafter, when the connection terminal of the card is detached from the terminal member, the moving member, that is, the card held by the moving member is accelerated toward the insertion slot by the force of the extended spring, and the card jumps out of the insertion slot. There is a concern that a collision sound may occur.
[0007]
Note that the above-described card pop-out and occurrence of a collision sound can be solved by increasing the force of the spring connecting the moving member and the rack. However, when the spring force is increased in this way, another problem that the feeling of insertion at the time of card insertion, that is, the feeling at the time of insertion, is deteriorated occurs.

[0034]
The first embodiment is particularly provided with an extruding means for extruding the card 1 in the ejection direction without the spring 12, that is, an extruding means for extruding the card 1 at the loading completion position in the direction of the insertion slot 6.
[0035]
The push-out means is provided on the moving member 8, for example, and a ratchet 18 that can be engaged with the front end of the rack 11 when the card 1 is ejected, and a support means that rotatably supports the ratchet 18 on the moving member 8, for example, A shaft 8a is included. Furthermore, a cam 17 that is provided on the cover 5 and rotates the ratchet 18 and a spring 19 that urges the ratchet 18 toward the cover 5 are included.
[0036]

The size is set to be larger than the size to be measured.
[0037]
The operation of the first embodiment configured as described above will be described below.
[0038]
[Insert / load card 1]
Before the card 1 is inserted, as shown in FIG. 1B, the ratchet 18 is held in a state of being urged so that its tip abuts against the cover 5 by the force of the spring 19. Has been. In such a state, as shown in FIG. 1, when the card 1 is inserted from the insertion slot 6 and pushed into the back side, the leading end 9 of the card 1 engages with the protrusion 10 of the moving member 8, and the card 1 The moving member 8 moves against the force of the spring 12 integrally with the pushing operation. That is, the feeling when the card 1 is inserted corresponds to the force of the spring 12 at this time.
[0039]
When the moving member 8 moves by a distance substantially corresponding to the dimension B in FIG. 1B, the moving member 8 engages with the loading start switch 15, and the loading start switch 15 is activated. During this time, an engaging claw (not shown) provided in the moving member 8 engages with the concave portion 2 of the card 1, and the card 1 is held so as to be movable integrally with the moving member 8 via the engaging claw.
[0040]
By the operation of the loading start switch 15 described above, the motor 14 is driven, and the gear mechanism 13 is rotated accordingly, whereby the rack 11 starts linear movement toward the back side of the apparatus. That is, loading is started as shown in FIG.
[0041]
As the rack 11 moves, the moving member 8 automatically moves in the same direction, that is, toward the back side via the spring 12, and the card 1 is moved to the lower side of the cover 5 integrally with the movement of the moving member 8. Move towards the storage.
[0042]
[Loading operation / loading completion]
As described above, when the rack 11 moves, the moving member 8 moves toward the back side, and the connection terminal 3 of the card 1 approaches the terminal member 7 disposed at the back side position, the ratchet is reached. 18 engages the cam 17, that is, the ratchet 18 starts to rotate upward against the force of the spring 19.
[0043]
When the moving member 8 is engaged with the loading completion switch 16 and the loading completion switch 16 is activated, the motor 14 is stopped. When the motor 14 is stopped, the gear mechanism 13 is stopped, the rack 11 is stopped, and the moving member 8 is stopped via the spring 12. As a result, the card 1 is held at the loading completion position as shown in FIG. In this state, as shown in FIG. 3B, the ratchet 18 is located on the cam 17, and the tip thereof faces the front end of the rack 11 with a slight gap. Further, the connection terminal 3 of the card 1 is in contact with the terminal member 7. That is, a contact pressure is formed between the connection terminal 3 and the terminal member 7 of the card 1. In this state, transmission / reception of signals to / from the card 1 is possible.
[0044]
[Card 1 ejection operation]
As described above, when an unillustrated eject operation is performed from the state where the card 1 is held at the loading completion position, the motor 14 is driven in reverse to the above. As a result, the gear mechanism 13 is reversely driven, and the rack 11 starts moving toward the insertion slot 6. At this time, as shown in FIG. 3 (b), the tip of the ratchet 18 is located on the cam 17 and faces the front end of the rack 11, so that the rack 11 is engaged with the ratchet 18, The ratchet 18 is pushed out toward the insertion slot 6. That is, the moving member 8 to which the ratchet 18 is fixed moves integrally with the movement of the rack 11 in the direction of the insertion port 6 via the ratchet 18. By this moving member 8, the card 1 starts moving in the direction of the insertion slot 6, that is, in the discharging direction.
[0045]
When the rack 11 continues to move and the moving member 8 moves via the ratchet 18, the contact between the connection terminal 3 and the terminal member 7 of the card 1 is released as shown in FIG. 4B. At this time, as shown in FIG. 4B, the ratchet 18 is still kept on the cam 17.
[0046]
When the rack 11 further moves from this state, the ratchet 18 and the cam 17 are disengaged, and the ratchet 18 is rotated downward in FIG. As a result, the ratchet 18 and the rack 11 are disengaged, and then the moving member 8 moves with the movement of the rack 11 via the spring 12. When the moving member 8 moves until it moves away from the loading start switch 15, the loading start switch 15 is activated, and the motor 14 is thereby stopped. When the motor 14 stops, the gear mechanism 13 stops and the rack 11 stops. Accordingly, the moving member 8 stops via the spring 12. When the moving member 8 is stopped, the state shown in FIG. 1 is reached, and the card 1 reaches the discharge position. That is, the card 1 is completely discharged. In this state, the card 1 can be taken out from the insertion slot 6.
[0047]
According to the first embodiment configured as described above, the ratchet 18 provided on the moving member 8 engages with the rack 11 when the card 1 is ejected. Therefore, the large moving force transmitted to the rack 11 is transmitted to the moving member 8 via the ratchet 11 and not via the spring 12. Thereby, even when the contact pressure between the connection terminal 3 and the terminal member 7 of the card 1 is high, it is not necessary to set the force of the spring 12 strongly and the card 1 is not accelerated by the spring force. 8 can be moved. Accordingly, the card 1 held by the moving member 8 can be smoothly discharged, and the card 1 can be prevented from popping out and the occurrence of a collision sound during the discharge.
[0048]
In addition, since the force of the spring 12 can be set without considering the contact pressure between the connection terminal 3 and the terminal member 7 of the card 1, it can be a weak force. Thereby, a good feeling can be obtained when the card 1 is inserted.
[0049]
Further, since the pushing means for pushing the card 1 in the discharging direction includes the ratchet 18, the shaft 8a, the cam 17, and the spring 19, the pushing means has a simple structure and is inexpensive to manufacture. can do.
[0050]
In addition, since the length of the cam 17 is set as described above, the rack 11 and the ratchet 18 are engaged to a position where they are not affected by the contact pressure between the connection terminal 3 and the terminal member 7 of the card 1. The combined state can be maintained, and there is no sudden speed change of the moving member 8 when the card 1 is discharged. Thereby, the stable discharge operation | movement of the card | curd 1 is realizable.
[0051]
  5 to 9 show the present invention.Reference exampleIt is explanatory drawing of. 5A and 5B are diagrams showing a state when the card is inserted, in which FIG. 5A is a plan view, and FIG. 5B is a cross-sectional view taken along line A5-A5 in FIG. 6A and 6B are diagrams illustrating a state at the start of loading, in which FIG. 6A is a plan view, and FIG. 6B is a cross-sectional view taken along line A6-A6 in FIG. 7A and 7B are diagrams showing a state when loading is completed, in which FIG. 7A is a plan view, and FIG. 7B is a cross-sectional view taken along line A7-A7 in FIG. FIGS. 8A and 8B are diagrams showing a state in the middle of card ejection, where FIG. 8A is a plan view and FIG. 8B is a cross-sectional view taken along line A8-A8 in FIG. Figure 9 shows thisReference exampleIt is a top view which shows the moving member with which it is equipped.
[0052]
  thisReference exampleThe pushing means for pushing the card 1 in the discharging direction without using the spring 12 is configured by a missing tooth 21 which is provided on the moving member 8 and can mesh with the gear mechanism 13 as shown in FIG. The pitch of the missing teeth 21 is set to be equal to the pitch of the rack 11, for example.
[0053]
The length dimension of the above-mentioned missing tooth 21 along the insertion / extraction direction of the card 1 corresponds to the distance that the moving member 8 moves from the loading completion position to the position where the contact between the connection terminal 3 of the card 1 and the terminal member 7 is released. The size is set to be larger than the size to be measured.
[0054]
The other structure is the same as that of the first embodiment shown in FIGS. 1 to 4 except for the ratchet 18 and the cam 17 that constitute the pushing means.
[0055]
  thisReference exampleThis operation is basically the same as that of the first embodiment except for the operation related to the missing tooth 21.
[0056]
[Insert / load card 1]
As shown in FIG. 5, when the card 1 is inserted from the insertion slot 6 and pushed inward, the moving member 8 moves integrally with the pushing operation of the card 1 as described above, and the loading start switch 15 is actuated. To do. During this time, an engaging claw (not shown) of the moving member 8 engages with the recess 2 of the card 1.
[0057]
When the loading start switch 15 is actuated, as shown in FIG. 6, the motor 14 is driven, the gear mechanism 13 is rotated, and the rack 11 is started to start linear movement toward the back side of the apparatus.
[0058]
[Loading operation / loading completion]
As the rack 11 moves, when the connection terminal 3 of the card 1 approaches the terminal member 7 disposed at the back side position, the missing tooth 21 of the moving member 8 starts to engage with the gear mechanism 13. Thereafter, the rotational force of the gear mechanism 13 is transmitted to the rack 11 and the moving member 8, and the rack 11 and the moving member 8 move to the back side.
[0059]
When the moving member 8 engages with the loading completion switch 16, the motor 14 stops, the gear mechanism 13 stops, and the rack 11 and the moving member 8 stop. As a result, the card 1 is held at the loading completion position as shown in FIG.
[0060]
[Card 1 ejection operation]
As described above, when the card 1 is held at the loading completion position and the ejection operation is performed and the motor 14 is driven in reverse, the gear mechanism 13 is driven in reverse. Thereby, the rack 11 and the moving member 8 meshing with the gear mechanism 13 start moving toward the insertion port 6 at the same time. By this moving member 8, the card 1 starts moving in the direction of the insertion slot 6, that is, in the discharging direction.
[0061]
When the rack 11 and the moving member 8 continue to move, the contact between the connection terminal 3 and the terminal member 7 of the card 1 is released as shown in FIG. 8B. At this time, the missing tooth 21 of the moving member 8 is still kept in mesh with the gear mechanism 13.
[0062]
When the rack 11 and the moving member 8 further move from this state, the meshing between the moving member 8 and the gear mechanism 13 is released, and then the moving member 8 moves with the movement of the rack 11 via the spring 12.
[0063]
When the moving member 8 moves until it moves away from the loading start switch 15, the motor 14 stops, the gear mechanism 13 stops, and the rack 11 stops. Along with this, the moving member 8 stops via the spring 12. As a result, the card 1 reaches the discharge position shown in FIG. 5 and the discharge operation is completed.
[0064]
  Configured like thisReference exampleAccording to the above, when the card 1 is ejected, the missing teeth 21 provided on the moving member 8 are kept engaged with the gear mechanism 13. Therefore, a large moving force is transmitted to the moving member 8 via the gear mechanism 13 without passing through the spring 12. Thus, similarly to the first embodiment described above, even when the contact pressure between the connection terminal 3 and the terminal member 7 of the card 1 is high, the moving member 8 is reliably moved without the need to set the force of the spring 12 strongly. be able to. As a result, the card 1 held by the moving member 8 can be smoothly discharged, and the card 1 can be prevented from popping out and the occurrence of a collision sound.
[0065]
Moreover, the force of the spring 12 can be made weak, and a good feeling can be obtained when the card 1 is inserted.
[0066]
Further, since the pushing means for pushing the card 1 in the discharging direction is constituted by the missing teeth 21 provided on the moving member 8, the construction of the pushing means is simple, and the production cost can be reduced.
[0067]
Furthermore, since the length dimension of the missing tooth 21 is set as described above, the missing tooth 21 and the gear mechanism 13 are moved to a position where they are not affected by the contact pressure between the connection terminal 3 and the terminal member 7 of the card 1. Can be held, and a rapid speed change of the moving member 8 does not occur when the card 1 is ejected. Thereby, the stable discharge operation | movement of the card | curd 1 is realizable.

As described above, when the card 1 is held at the loading completion position and the ejection operation is performed and the motor 14 is driven in reverse, the gear mechanism 13 is driven in reverse. As a result, the rack 11 meshing with the gear mechanism 13 moves, and the pin 23 is pushed through the second straight portion 26 of the cam groove 24 by being pushed by the edge of the long hole 22 formed in the rack 11. Start moving in the direction of. At this time, since the pin 23 engages with the engaging portion 28 of the moving member 8, the moving member 8 starts moving toward the insertion port 6 in conjunction with the movement of the pin 23. By this moving member 8, the card 1 starts moving in the direction of the insertion slot 6, that is, in the discharging direction.
[0080]
When the rack 11 continues to move and the moving member 8 moves through the pin 23, the contact between the connection terminal 3 of the card 1 held by the moving member 8 and the terminal member 7 is released as described above. At this time, the pin 23 is still in the second linear portion 26 of the cam groove 24. Thereafter, the pin 23 moves from the skewed portion 27 of the cam groove 24 into the first linear portion 25. Accordingly, the pin 23 moves downward in the long hole 22 of the rack 11 in FIG.
[0081]
When the pin 23 moves into the second linear portion 26 of the cam groove 24, the engagement between the pin 23 and the engaging portion 28 of the moving member 8 is released, and then the moving member 8 is interposed via the spring 12. The rack 11 moves as the rack 11 moves.
[0082]
When the moving member 8 moves until it moves away from the loading start switch 15, the motor 14 stops, the gear mechanism 13 stops, and the rack 11 stops. Along with this, the moving member 8 stops via the spring 12. As a result, the card 1 reaches the discharge position, and the discharge operation is completed.
[0083]
  No. 1 configured in this way2According to the embodiment, when the card 1 is ejected, the pin 23 pushed by the edge of the long hole 23 of the rack 11 is kept in a state of being engaged with the engaging portion 28 of the moving member 8. Therefore, the large moving force transmitted to the rack 11 is transmitted to the moving member 8 via the pin 23 without passing through the spring 12. Thus, similarly to the first embodiment described above, even when the contact pressure between the connection terminal 3 and the terminal member 7 of the card 1 is high, the moving member 8 is reliably moved without the need to set the force of the spring 12 strongly. be able to. Along with this, the card 1 held by the moving member 8 can be smoothly discharged, and the card 1 can be prevented from popping out and generating a collision sound.
[0084]
Moreover, the force of the spring 12 can be made weak, and a good feeling can be obtained when the card 1 is inserted.
[0085]
Further, the pushing means for pushing the card 1 in the discharging direction is constituted by the pin 23, the engaging portion 28 provided in the moving member 8, the long hole 22 provided in the rack 11, and the cam groove 24 provided in the cover 5. Therefore, the structure of the extrusion means is simple, and the production cost can be reduced.
[0086]
Further, since the length dimension of the second straight portion 26 of the cam groove 24 is set as described above, the pin is moved to a position where it is not affected by the contact pressure between the connection terminal 3 and the terminal member 7 of the card 1. 23 and the engaging portion 28 of the moving member 8 can be held, and a rapid speed change of the moving member 8 when the card 1 is discharged does not occur. As a result, a stable card 1 ejection operation can be realized.
[0087]
【The invention's effect】
As described above, according to the present invention, since the pushing means for pushing the card in the ejecting direction without using the spring is provided, it is not necessary to set the force of the spring for connecting the moving member to the rack. The card held at the completion position can be smoothly discharged. Accordingly, it is possible to prevent the card from popping out at the time of ejection and the occurrence of a collision sound, which have been feared in the past. In addition, it is possible to set the above-described spring force weakly, and when it is set so weak, a good feeling can be ensured when the card is inserted.

The above size is set. As a result, the engagement state between the rack and the ratchet can be maintained up to a position where the influence of the contact pressure between the connection terminal of the card and the terminal member is eliminated, and a rapid speed change of the moving member occurs when the card is discharged. There is nothing. Therefore, a stable card ejection operation can be realized.
[0092]
According to the present invention, the push-out means is provided on a pin that moves as the rack moves between a loading start position and a loading completion position, and the moving member, and the pin is engaged when the card is ejected. And a mating engagement portion. And a slot provided in the rack and extending in a direction substantially perpendicular to the card insertion / removal direction, and a cam groove provided in a cover covering the card accommodating portion, wherein the pin is connected to the slot. The cam groove is inserted into the cam groove. This simplifies the configuration of the extrusion means and can reduce the production cost.
[0093]
According to the present invention, the cam groove has a first straight portion formed so that the pin is positioned at the start of loading and is along the insertion / removal direction of the card. In addition, the pin is located when loading is completed, and a second straight portion formed on a path different from the first straight portion along the card insertion / removal direction, and the first straight portion and the second straight line. And a skewed portion connecting the portions. Further, the length dimension of the second linear portion is set to a dimension equal to or larger than the distance corresponding to the distance that the moving member moves from the loading completion position to the position where the contact between the connection terminal of the card and the terminal member is released. It is set. As a result, the engagement state between the pin and the engaging portion of the moving member can be maintained up to a position where it is not affected by the contact pressure between the connection terminal of the card and the terminal member. No speed change occurs. Therefore, a stable card ejection operation can be realized.
