Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card connector for exchanging information with a card inserted in a housing, and more particularly, to a card connector configured to electrically insert and eject a card.

[0002]

2. Description of the Related Art In recent years, PC cards, memory cards,
The use of card-shaped information recording media such as C-cards (collectively referred to as cards hereinafter) has been expanding, and various card connectors for receiving and exchanging information for this card have been put to practical use. Have been. Such a card connector is configured to receive a card inserted from an insertion opening formed in the housing into the housing and transmit information.

[0003]

However, in the card connector having such a structure, the insertion and removal of the card are generally performed by hand, so that information is exchanged between the card and the connector. In some cases, the card was pulled out and the information was not reliably transmitted.
In order to prevent such a situation, there is a type in which a card is inserted and removed electrically, but a large-sized belt device or the like is used, so that a connector size becomes large. For example, it is not used as a card reader for a vehicle. Was unsuitable.

The present invention has been made in view of such a problem, has a simple and compact configuration, and has no danger of pulling out a card during the exchange of information. It is an object of the present invention to provide a card connector that can be reliably operated.

[0005]

In order to achieve such an object, a card connector according to the present invention has a housing in which a card insertion slot is formed, and a card connector rotatably supported in the housing and inserted through the insertion slot. A pair of roller members for holding the inserted card, a normal operation of rotating the roller member in a direction of receiving the card into the housing, and a reverse operation of rotating the roller member in a direction of discharging the card from the housing. Roller member driving means capable of performing an operation (for example, the electric motor 3 in the embodiment)
3), a first detector (for example, the first limit switch 71 in the embodiment) that detects a state in which the card is inserted into the insertion slot and outputs an insertion signal, and a predetermined position where the card exchanges information. A second detector that detects the position and outputs an acceptance signal (for example, the second detector in the embodiment)
Limit switch 72), manually operable card ejection command means (for example, card ejection button 80 in the embodiment), and card ejection command means operated in a state where an acceptance signal is output from the second detector. A discharge command signal output unit (e.g., a discharge command signal output unit in the controller 90 in the embodiment) that outputs a discharge command signal, and a third signal that detects a state in which the card is almost discharged from the housing and outputs a discharge signal. Detector (for example,
The third limit switch 73 in the embodiment) and the first
The roller member driving means is operated normally based on the insertion signal output from the detector, and the normal operation is stopped based on the receiving signal output from the second detector, and the discharge output from the discharge command signal output means is performed. Control means for performing a reverse operation of the roller member driving means based on the command signal and stopping the reverse operation based on a discharge signal output from the third detector (for example, a control unit in the controller 90 in the embodiment) And is provided.

In the card connector configured as described above, the card is first inserted through an insertion hole provided in the housing. The insertion of the card into the insertion slot is detected by the first detector, and an insertion signal is output to the control means.
The control means having received the insertion signal causes the roller member driving means to perform a normal operation to start the rotation of the roller member. However, when the card is further pushed in and comes into contact with both roller members, the roller member holds the card inside the housing while holding the card. I will draw in. When the card is pulled into a predetermined position for exchanging information, this is detected by the second detector and an acceptance signal is output to the control means. The control means having received the reception signal stops the normal operation of the roller member driving means, so that the rotation of the roller member is stopped, and information can be exchanged between the card and the connector.

When the ejection command means is operated from the state in which the card is received in the housing, that is, the state in which the reception signal is output from the second detector, the ejection command signal is output from the ejection command signal output means. A signal is output. The control means reversely operates the roller member driving means according to the output of the discharge command signal. When the card is almost ejected from the housing by such a reverse operation, this is detected by the third detector and a discharge signal is outputted to the control means. The control means receives the discharge signal and operates the roller member driving means in reverse. To stop. In this state, the card can be pulled out by hand, and the final removal of the card from the housing is performed by hand.

In the card connector having such a configuration, first, although insertion and ejection of the card are performed electrically, the configuration is simple and compact because a large belt device or the like is not used unlike the conventional one. Becomes For this reason, it is advantageous in terms of cost and is suitable for use in vehicles. Further, the insertion and ejection of the card into and from the housing are performed via the control means, so that the timing for starting ejection of the card can be adjusted as desired. For this purpose, for example, a fourth detector (for example, a timer 90a in the controller 90 in the embodiment) that detects a state in which the exchange of information with the card has been completed and outputs a termination signal,
If the control means is configured to perform the reverse operation only after the end signal is output from the fourth detector, the state in which the exchange of information between the card and the card connector has not been completed. This prevents the card from being pulled out of the housing.

Further, it is preferable to provide a manual roller member driving means (for example, a manual roller driving knob 82 in the embodiment) capable of manually rotating and driving the roller member. Even if a failure or the like occurs, the card can be taken out without fail, and safety is enhanced.

As shown in FIGS. 2 and 3, an electric motor 33 is mounted on the right side of the housing body 11 with the rotating shaft 33a positioned in the front-rear direction. An intermediate shaft 34 extending parallel to the rotation shaft 33a is rotatably supported by shaft support portions 44 and 45 formed on the housing body 11. A gear 51 is attached to the rear end of the rotating shaft 33a, and meshes with a gear 52 attached to the center of the intermediate shaft. Worm 5 is provided at the rear end of the intermediate shaft 34.
The worm 53 is engaged with a worm wheel 54 attached to the right end of the upper shaft 31a. The speed reduction mechanism composed of the worm 53 and the worm wheel 54 is connected to the electric motor 3.
The number of teeth that can sufficiently reduce the number of rotations of 3 is selected and used.

a is driven. Therefore, by rotating the electric motor 33 in the forward and reverse directions, the card 2 in the housing 10 can be transported in the front-rear direction while being held between the upper and lower cylindrical rubber portions 31b and 32b.

As shown in FIGS. 3 and 4, a connector body 60 is attached to the rear of the upper and lower roller members 31, 32, and holds the card 2 conveyed rearward by the roller members 31, 32. . The connector body 60 includes a connector lower portion 60a and a connector upper portion 60b detachably attached to the upper portion of the connector lower portion 60a. The connector lower portion 60a has a side wall portion 61 for holding the left and right side surfaces of the card 2, 2 that holds the lower surface of the card 2 and the front end (rear end) of the inserted card 2
And a left and right rear wall portion 64 having a contact surface 64a with which the card 2 abuts.
The upper wall portion 63 holds the upper surface side. FIG. 3 shows a state in which the connector upper part 60b is detached from the connector main body 60.

As shown in FIG. 3, a plurality of contact grooves 62a extending in the front-rear direction are provided in the lower wall portion 62 in two front and rear rows, and from each of these contact grooves 62a, the lower wall portion 62 is formed. The contact portion 65a of the built-in contact 65 protrudes upward. That is, as shown in FIG. 4, the contact portion 65a of the contact 65 is located in the space 66 between the lower wall portion 62 and the upper wall portion 63. Each contact 65 is made of a conductive elastic material, and the contact portion 65a is elastically deformed so as to sink into the lower wall portion 62 when the card 2 is inserted into the space 66 and a pressing force acts from above. When the pressing force is removed, it returns to the space 66 by the elastic force.

Between the guide portion 22 and the roller members 31 and 32, an upwardly extending arm portion 71a (having a roller at the distal end) is turned on when pressed downward by receiving a pressing force. A first limit switch 71 for outputting a signal and returning to an initial position when such a pressing force is removed and outputting an OFF signal is provided. The arm 71a of the first limit switch 71 is located at a position where the leading end of the card 2 passes before the card 2 inserted from the insertion slot 21 is sandwiched between the upper and lower roller members 31 and 32. In addition, when the card 2 is inserted into the insertion slot 21, the output signal from the first limit switch 71 switches from an off signal to an on signal. Therefore, it is possible to detect the state in which the card 2 is inserted into the insertion slot 21 based on the switching of the on / off signal output from the first limit switch 71.

An ON signal is output between the left and right rear wall portions 64 when the forwardly extending arm portion 72a is pressed backward by receiving a pressing force, and such a pressing force is removed. A second limit switch 72 is provided for returning to the initial position and outputting an off signal when the switch is turned off. The arm 72 a of the second limit switch 72 is connected to the connector body 60.
When the card 2 is held by the connector main body 60, the output signal from the second limit switch 72 is located at a position where the card 2 is pushed rearward when the leading end of the card 2 contacts the rear wall portions 64, 64. Switch from an off signal to an on signal. Therefore, the second limit switch 7
It is possible to detect a state in which the card 2 is held by the connector main body 60 based on the switching of the on / off signal output from the connector 2.

The roller members 31, 32 and the space 6
6, an ON signal is output when the upwardly extending arm portion 73a (having a roller at the distal end) is pressed downward by receiving a pressing force. When removed, return to the initial position and output an off signal.
A limit switch 73 is provided. The arm portion 73a of the third limit switch 73 is connected to the roller members 31, 3
2 is located at a position where the card 2 conveyed by the card 2 passes before entering the space 66. When the card 2 is ejected from the housing 10 at the time of ejection of the card 2, the third The output signal from the limit switch 73 is switched from an ON signal to an OFF signal. Therefore, based on the switching of the on / off signal output from the third limit switch 73, it is possible to detect a state in which the card 2 is almost discharged from the housing 10.

A card ejection button 80 that can be manually operated is provided on the front surface of the housing body 11.
The card ejection button 80 outputs an ON signal when pressed, and outputs an OFF signal when released.

A controller 90 connected to a power supply outside the housing 10 via a power cable 91 is provided behind the intermediate shaft 34.
To 0, an on / off signal from the first to third limit switches 71, 72, 73 input via the cables 101, 102, 103 and an on / off signal from the card ejection button 80 input via the cable 104 are input. It is supposed to be.

The controller 90 has a discharge command signal output section and a control section. The discharge command signal output section outputs an ON signal from the card discharge button 80 while the ON signal is being output from the second limit switch 72. Is output, the output of the discharge command signal is started, and thereafter, the output is continued until the OFF signal is output from the first limit switch 71. On the other hand, the controller controls the cable 1 based on the on / off signals output from the first to third limit switches 71, 72, 73 and the presence or absence of the discharge command signal.
An electric force is supplied to the electric motor 33 via the electric motor 05 to control the forward / reverse rotation and stop of the electric motor 33. Switching between forward and reverse rotation of the electric motor 33 is performed by changing the direction of the current flowing through the motor winding by the controller 90.

The operation of the electric motor 33 for rotating the roller members 31 and 32 in the direction in which the card 2 is received in the housing 10 is referred to as a normal operation, and the roller 2 is moved in the direction of discharging the card 2 from the housing 10. Members 31, 32
When the operation of the electric motor 33 for driving the rotation of the first limit switch is referred to as a reverse operation, the control unit of the controller 90 outputs the insertion signal (the ON signal output after the OFF signal) output from the first limit switch 71, as described later in detail. Signal), the normal operation of the electric motor 33 is stopped, and the normal operation is stopped based on the reception signal (ON signal output after the OFF signal) output from the second limit switch 72. Control is performed such that the electric motor 33 is operated in reverse based on the output command signal output, and the reverse operation is stopped based on the output signal output from the third limit switch 73 (off signal output after the on signal). .

In the controller 90, a timer 90a for measuring an elapsed time from when the second limit switch 72 is turned on and outputting an end signal when the measured time exceeds a predetermined time. Is provided, and even if the discharge command signal is output from the discharge command signal output unit, the control unit treats this as a valid signal unless it is after the end signal is output from the timer 90a. Not to be. That is, the control unit does not perform the reverse operation of the electric motor 33 until a predetermined time has elapsed since the second limit switch 72 was turned on even if the discharge command signal was output. The predetermined time is set as a time from when the card 2 is held by the connector main body 60 to when the exchange of information between the card 2 and the card connector 1 is completed.

As shown in FIGS. 1 to 3, a knob insertion port 81 is provided on the front surface of the housing body 11.
Here, a manual roller drive knob 82 as shown in FIG. 1 can be inserted. A key groove 83 formed at the tip of the manual roller drive knob 82 can be fitted with a key portion 34a (see FIG. 3) formed in the intermediate shaft 34, and the key groove 83 is fitted to the key portion 34a. The intermediate shaft 34 can be rotated by twisting the manual roller drive knob 82 around the axis in the fitted state,
The roller members 31 and 32 can be driven to rotate manually.

FIG. 5 shows the control patterns of the electric motor 33 in the control section of the controller 90.
This is shown corresponding to a combination of output signals from the limit switches 71, 72, 73 and the presence / absence of output of the discharge command signal. Here, SW1, SW2, SW3 in the table
Are the first to third limit switches 71, 72, 7 respectively.
3 is shown.

The insertion and ejection of the card 2 will be described with reference to the table of FIG. 5. First, when the card 2 is not inserted into the insertion slot 21, the first to third limit switches 7 are set.
1, 72 and 73 output an OFF signal, the electric motor 33 is stopped by the controller 90 (corresponding to a control pattern), and the roller members 31 and 3 are turned off.
2 is stationary.

In such a state, the card 2 is inserted into the insertion slot 21.
, The leading end (rear end) of the card 2 pushes the arm 71a of the first limit switch 71 downward, and the first
Since the output signal of the limit switch 71 switches from off to on (output of an insertion signal), the controller 90 rotates the electric motor 33 in the forward direction (corresponding to a control pattern). As a result, the roller members 31 and 32 start to rotate from a stationary state, and the top end of the card 2 is moved up and down by the upper and lower cylindrical rubber portions 3.
When the card 2 is pushed in until it comes into contact with the card 1b, 32b, the card 2 is pulled in the direction of the connector main body 60 due to friction between the cylindrical rubber portions 31b, 32b and both surfaces of the card 2 (direct operation of the electric motor 33). .

When the leading end of the card 2 passes through both roller members 31 and 32 and pushes the arm 73a of the third limit switch 73 downward by the normal operation of the electric motor 33, the third limit switch 73 Is switched from off to on. However, even in such a state, the controller 90 rotates the electric motor 33 in the forward direction (corresponding to a control pattern), so that the above-described normal operation is continued.

The card 2 is received and held by the connector main body 60 by such a normal operation, and when the leading end of the card 2 comes into contact with the contact surface 64a of the rear wall 64 of the connector main body 60 (the card 2 in this state is removed). The arm 72 a of the second limit switch 72 is pressed by the leading end of the card 2. As a result, the output signal from the second limit switch 72 switches from off to on (output of an acceptance signal), and the controller 90 stops the electric motor 33 (corresponding to a control pattern). As a result, the conveyance of the card 2 to the rear by the roller members 31 and 32 is stopped, and the contact (not shown) on the card 2 comes into contact with the contact 65 on the card connector 1 to exchange information between them. Done.

When the card ejection button 80 is pressed while the card 2 is located at a predetermined position for exchanging information (at this time, an ON signal is output from the second limit switch 72), the card ejection button 80 is pressed. The output signal from 80 is switched from off to on, and a discharge command signal is output from the discharge command signal output unit of the controller 90. The control unit of the controller 90 performs control to rotate the electric motor 33 in the reverse direction based on the output of the discharge command signal (corresponding to a control pattern). As a result, the roller members 31 and 32 start rotating from a stationary state, and the card 2 is conveyed in a direction of being ejected from the connector main body 60 (reverse operation of the electric motor 33). However, as described above, even if the discharge command signal is input, the control unit does not drive the electric motor 33 until the above-described predetermined time has elapsed since the second limit switch 72 was turned on. Only when the output is performed after a lapse of time, the electric motor 33 is rotated in the reverse direction. The reason why the reverse operation of the electric motor 33 is not performed until a predetermined time has elapsed since the second limit switch 72 was turned on is as follows.
This is to ensure that the exchange of information between the card 2 and the card connector 1 is completed.

When the card 2 is ejected by the reverse operation of the electric motor 33, the front end (rear end) of the card 2 is separated from the contact surface 64a of the rear wall 64, and the second limit switch is turned on. Since the pressing force pressing the arm 72a of the arm 72 is removed, the arm 72a returns to the initial position before the pressing. As a result, the output signal from the second limit switch 72 switches from on to off. Even in such a state, the controller 90 rotates the electric motor 33 in the reverse direction (corresponding to the control pattern), so that the reverse operation is performed. To be continued.

The card 2 is ejected by such a reverse operation, and the leading end of the card 2 is moved to the third limit switch 7.
After passing over the third limit switch 3, the pressing force from the card 2 acting on the arm 73a of the third limit switch 73 is removed, and the arm 73a returns to the initial position before the pressing. At this time, since the output signal from the third limit switch 73 switches from ON to OFF (output of the discharge signal), the controller 90 performs control to stop the rotation of the electric motor 33 (corresponding to a control pattern). This allows the controller 9
0 stops the rotation of the roller members 31 and 32,
Since the roller members 31 and 32 continue to rotate for a while due to inertia, the leading end of the card 2 has cylindrical rubber portions 31b and 32b.
Pushed forward. Therefore, the card 2 can be pulled out of the housing 10 by hand.

When the card 2 is pulled out from such a state, the pressing force acting on the arm 71a of the first limit switch 71 from the card 2 is removed, and the arm 71a returns to the initial position before the pressing. . At this time, the output signal from the first limit switch 71 is switched from on to off, whereby the electric motor 33 is not driven by the controller 90, and the roller members 31, 32 remain stationary. When the card 2 is pulled out of the housing 10 in this manner, the first limit switch 7
Since the signal output from 1 is turned off, the discharge command signal output unit of the controller 90 stops outputting the discharge command signal as described above (corresponding to a control pattern).

As described above, the card connector 1 according to the present invention
First, although the card 2 is inserted and ejected electrically, the configuration is simple and compact because a large belt device is not used unlike the prior art.
For this reason, it is advantageous in terms of cost and is suitable for use in vehicles. The card 2 is inserted into and ejected from the housing 10 through the controller 90, and the timing at which the card 2 is ejected can be adjusted as desired. This prevents a situation in which the card 2 is pulled out of the housing 10 in a state where the exchange of information with the card 1 has not been completed.

If an electrical failure occurs while the card 2 is received in the housing 10,
The manual roller drive knob 82 is inserted into the knob slot 81 of the housing 10, and the key groove 83 is fitted into the key portion 34 a and twisted in the direction of the reverse operation of the electric motor 33, whereby the roller members 31 and 32 are manually operated. Can be rotated to eject the card 2. As described above, the card connector 1 allows the card 2 to be reliably removed even when an electrical failure or the like occurs, thus enhancing safety.

Although the embodiment of the card connector according to the present invention has been described above, the scope of the present invention is not limited to the above-described one. For example, the configuration of the roller members 31, 32 is such that the upper and lower shafts 31a, 32a in the above-described example.
Although the cylindrical rubber portions 31b and 32b are attached to the above, they may be integrally formed. Further, the arrangement and configuration of the electric motor 33 for rotating and driving the roller members 31 and 32, the gears and the shafts do not necessarily have to be the same as in the above-described example. A normal operation for driving the roller members 31 and 32 to rotate in a receiving direction, and a roller member 31 and 3 for discharging the card 2 from the housing 10.
Any configuration may be used as long as it is possible to perform a reverse operation of rotating the drive 2.

In the above embodiment, the manual roller drive knob 82 is detachable from the intermediate shaft 34. However, the manual roller drive knob 82 and the intermediate shaft 3
4 and the manual roller drive knob 82 may always be protruded from the housing 10. However, in this case, when the electric motor 33 rotates, the manual roller drive knob 82 also rotates.

In the above embodiment, the card 2
A detector (corresponding to the first limit switch 71) for detecting a state in which is inserted into the insertion port 21 and outputting an insertion signal;
A detector (corresponding to the second limit switch 72) for detecting a state where the card 2 is located at a predetermined position for exchanging information and outputting a reception signal, and detecting a state where the card 2 is almost discharged from the housing 10. Each of the detectors (corresponding to the third limit switch 73) that outputs a discharge signal is a limit switch, but these need not necessarily be limit switches, and may be other detectors. Further, these detectors may not be of a contact type, and may be of a non-contact type such as an optical sensor. Further, in the above-described embodiment, the exchange of information between the card 2 and the card connector 1 is of a contact type via a contact, but this is not necessarily a contact type, and a non-contact type may be used. It may be something.

Further, the limit switches 71, 73
In the above-described embodiment, the ON signal is output when pushed downward, but the ON signal is output when pushed backward and swings. You may. Further, in the above embodiment, the timer 90a is provided for detecting a state in which the exchange of information with the card 2 has been completed and outputting an end signal, and the controller 90 is provided only after the end signal is output from the timer 90a. The reverse operation was performed. However, in the case of a system in which the exchange of information with the card 2 ends instantly, or in the case where the card 2 is ejected during the exchange of signals, there is no particular inconvenience. For example, such a configuration is not necessary.

[0041]

As described above, in the card connector according to the present invention, first, while the card is inserted and ejected electrically, a conventional large-sized belt device is used. Since it is not provided, the configuration is simple and compact. For this reason, it is advantageous in terms of cost and is suitable for use in vehicles. In addition, the insertion and ejection of the card into and from the housing are performed via the control means, and the timing for starting the ejection of the card can be adjusted as desired. It is possible to prevent the card from being pulled out of the housing in a state where the exchange of information has not been completed.
