Abstract

PROBLEM TO BE SOLVED: To provide a discharging mechanism for a card connector to prevent data and a circuit part in a card from being electrically destroyed by giving a warning to a user before the card is discharged by an error. SOLUTION: A protective button 11 is disposed on the front surface of an eject button 10 normally pushed, a shutter 17 is attached to its tip through a protective shaft 20 by utilizing a spring 12, the output level of a light detecting element on a base 18 is varied by opening and shutting the shutter 17, and in addition, a card ejector 14 is locked by a stopper 22. Thereby, if a card is forced to be discharged by an error while reading and writing card data, a warning is given from the device side before the card is discharged, and data and a circuit part in the card is prevented from being electrically destroyed with a simple structure.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PCMCIA card connector, an IC card connector, and a floppy disk drive, and more particularly, to a mechanism for ejecting these cards and disks.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional card connector having an ejection mechanism is connected to an eject button 10, an eject shaft 19 connected to the eject button 10, and an end of the eject shaft 19. A card ejector 14 for ejecting the mounted card and the like, a guide rail 21 for slidingly mounting the card and the like to the connector 2, a connector pin 15 mounted on an apparatus board, and the connector pin 15 being mounted. And a screw mounting guide 13 for fixing the connector 2 to the device substrate.

As shown in FIG. 3, a card connector without a discharge mechanism includes a guide rail 21 for slidingly mounting a card 5 and the like, a connector pin 15 mounted on an apparatus board, and a And a screw mounting guide 13 for fixing.

The operation of the card connector ejection mechanism is as follows.
As shown in FIG. 2, the eject button 10 is pushed in the direction a, the card ejector 14 rotates in the direction b around the axis via the eject shaft 19, and the protrusion at the tip of the card ejector 14 pushes the card 5. As a result, the guide rail 21 is discharged in the direction c.

FIG. 3 shows a card connector without an ejection mechanism, so that the card 5 is manually inserted into and removed from the guide rail 21 by a user.

[0006]

However, in the conventional card connector, when a card ejection operation is performed by a user while data is being read from or written to an IC card or the like from the device side, data in the card is not stored. Alternatively, there is a problem that the circuit unit may be electrically destroyed.

Therefore, an object of the present invention is to provide a device in which, when a card is ejected while data is being read from or written to the card, the output signal of the photodetector is sent to the apparatus before the card is actually ejected. An object of the present invention is to provide a card connector provided with a discharge mechanism for simultaneously pressing a card ejector and fixing the card ejector with a stopper mounted on a substrate to prevent an eject button from being pressed.

[0008]

In order to solve the above-mentioned problems, a card connector according to the present invention comprises: an eject button pressed to eject a card; an eject shaft connected to the eject button; A protection button for covering the protection button, a spring fixed inside the protection button and sliding the protection button, a protection shaft coupled to the protection button, a shutter attached to a tip of the protection shaft, and opening and closing of the shutter. The output level is changed, and the photodetector mounted on the board, the card ejector that ejects the card at the protrusion at the tip opposite to the eject shaft, and the card ejector when the card is inserted are fixed. And insert the card into the stopper Characterized in that it consists of a guide rail to de attached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a discharge mechanism for a card connector according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a configuration diagram of a card connector ejection mechanism according to an embodiment of the present invention.

As shown in FIG. 1, an ejection mechanism for a card connector according to an embodiment of the present invention includes an eject button 10 which is normally pushed for ejecting a card, and an eject shaft 19 connected to the eject button 10.
And a protection button 11 that covers the eject button 10 and is pressed first, a spring 12 fixed inside the protection button 11 for sliding the protection button 11 back and forth, and a protection button 11 And a shutter 17 mounted vertically on the tip of the protection shaft 20, and a photodetector that is opened and closed by the shutter 17 and that is mounted on a substrate 18 for changing an output level. A card ejector 14 having a groove for fixing the stopper 22 by rotating the eject shaft 19 around its axis by the movement of the eject shaft 19 and ejecting the card 5 by a projection at the tip opposite to the eject shaft 19; A stopper 22 for locking the ejector 14 and the card 5 are inserted and slide-mounted. A guide rail 21 for, and a screw mounting guide 13 for implementing secure the card connector 1 to the device substrate.

Next, the operation of the card connector ejection mechanism according to one embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the operation of the ejection mechanism of the card connector according to the embodiment of the present invention is as follows. First, the protection button 11 is pressed in the direction A before the ejection button 10 is pressed, The protection shaft 20 and the shutter 17 coupled to 11 move in the direction B from the positions of 20a and 17a before the protection button 11 is pressed to become 20b and 17b, respectively. The state in which the light of the element 16 is blocked is released, the output level of the light detecting element 16 is changed, and a signal is transmitted to the device together with the card sensor signal in the connector pin 15. At the same time, the card ejector 14 is temporarily locked by the stopper 22 entering the groove of the card ejector 14. In this state, the inserted card 5 has not been ejected from the card connector 1 yet, and a change in the output level of the light detecting element 16 informs the user of a warning sound or a message indicating that the card ejection is invalid from the apparatus side. This prevents electrical destruction of data and circuit portions in the IC card.

When data is not being read from or written to the card 5 from the apparatus side, the alarm button is pressed even if the output level of the light detecting element 16 is changed by pushing the protection button 11 by the spring 12 as described above. And messages are not displayed. Therefore, when the eject button 10 is pushed in, the card ejector 14 attached to the eject shaft 19 releases the lock of the stopper 22 via the eject shaft 19 fixed to the screw attachment guide 13, and the card ejector 14 The card 5 mounted on the card connector 1 can be ejected in the direction C by using the guide rail 21 by the projection at the end opposite to the eject shaft 19 by rotating in the direction D about the axis.

[0015]

As described above, according to the card connector ejecting mechanism of the present invention, the protection button is pressed first before the eject button is pressed, so that the IC mounted on the card connector is pressed. If the user accidentally ejects a card while reading / writing data from / to the card from the device, a warning sound or message is output from the device, and the card ejector temporarily stops at the stopper. Locking has the effect of preventing electrical destruction of data and circuit portions in the card.
