Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a manual card reader for handling magnetic cards, etc., and more particularly to a card reader with excellent card processing performance.

(B) Prior Art In general, this type of card reader turns on the power of the card data processing unit based on the manual insertion of the card into the card insertion slot, and simultaneously processes the card data. Turn off the power based on the card removal/removal operation.
The power is turned on only when a card is inserted to save energy.

In this case, power is input to the card data processing circuit in conjunction with the manual insertion of the card, but this circuit does not start up sufficiently and the data is processed without sufficient circuit stabilization time. In some cases, data processing errors such as parts of the data being skipped may occur.

Furthermore, when inserting a card, the user pushes the front of the card with his or her fingertips, which causes the front end of the card to wobble, resulting in an unstable insertion operation, resulting in unreliable card processing.

(c) Problems to be solved by the invention This invention aims to save energy in the power supply while
``i'' - Allow sufficient rise time for the processing circuit.

The present invention aims to provide a card reader that is stable and capable of processing card data in a stable manner. , - Based on "C", the card reader (which processes card data by switching the power supply of the card data processing section) detects that a card has been inserted into the card inserter "J". A card detection means is used to detect the card.
This card reader is equipped with a power supply control means for turning off the power of a card data processing section, and a data processing control means for operating a card data processing section when a card is removed.

(e) Effect of the Invention According to this year's report, based on the card detection means detecting that a card has been inserted into the card insertion I, the power supply control means operates the card data processing unit to perform a card transaction. When the power is turned on and the card is removed, the card data processing section is operated by the data processing control means to process the card data. If no card has been removed or the card is not detected, the power to the card data processing section is turned off.

(f) Effects of the invention In this way, since card data is processed when the card is removed after the card is inserted and the card data processing circuit has sufficiently started up, it is possible to process the card data while the circuit is in a stable state. Moreover, since this data processing does not interfere with the energy saving of the power supply due to the short-term power supply that turns on and off in conjunction with the insertion and removal of the card, data processing can be performed with this energy saving in mind. As a result, the card reader can be reliably downsized by utilizing a small power source such as a battery.

In addition, when removing the card, the card is pulled out by grasping the front side of the card with the fingertips, so it can be removed stably without wobbling, and data processing during this removal operation is highly reliable.

(l.) Embodiment An embodiment of the present invention will be described below in detail based on the drawings F.6 The drawings show a composite card reader, and in FIGS. 1 and 2, this composite card reader 1] is It can handle IC cards, magnetic cards, and cards that share these, and can handle 12 of these types of cards or 1 composite card reader.
[6] Composite card reader described in I-7] 1 has a card 12 on a curved surface.
It has a card insertion slot 13 for inserting a
A slider 19 that slides back and forth in conjunction with the insertion/removal operation of the card 12 is disposed within the card passage 18 surrounded by the card slot 7 .

1. The slider 19 mentioned above has slide shafts of 20°20° on both sides.
The card 12 is pivotably supported by the card 12, and is allowed to slide in the insertion/removal direction of the card 12. Usually, a spring 21 supports the card insertion [1
When the tip of the card 12 comes into contact with the card receiving surface 22 vertically provided on the front side of the slider 19, the card 12 is biased to be positioned on the 13 side. Slide the slider 19 against the biasing force of the spring 21 to a position W at the front slider stopper surface 23.

By moving one slider forward to this stopper position,
The contact 25 of the tilting lever 24 attached to this
It contacts the IC contacts of the C card and processes the card's data.

In addition, the magnetic head 26 provided at the starting end of the card passage 18 makes contact with the magnetic head 26 of the magnetic card inserted therein, and processes the magnetic data of the magnetic card. It is done.

Incidentally, the card insertion slot 13 is provided with a concave recess 27 that allows the fingertips to be inserted when manually inserted, and a shutter lever 28 that allows and restricts the insertion and removal of the card 12 inserted therein. It is set up.

This shutter lever 28 is designed to move the shutter lever 28 downward and lock the card in order to prevent the IC card from being accidentally removed during data processing. When this is completed, the shutter lever 28 is moved upward to release the lock and allow the IC card to be removed. 31 and lock release solenoid 32, the shutter lever 28
Open/close operations.

Normally, the shutter lever 28 moves upward and is in an open state that allows insertion of a card, and by turning on the lock solenoid 31, the lock lever 33, shutter interlocking lever 30, and link mechanism 29 are activated. The shutter lever 28 is moved down to lock the inserted card. Further, by turning on the lock release solenoid 32, the shutter lever 28 is moved upward via the shutter interlocking lever 30 and the link mechanism 29 to release the lock, thereby allowing the IC card to be removed.

In the figure, SWl is a card insertion detection switch, which detects card insertion in conjunction with the movement of the left side plate 16 that moves laterally based on the card insertion operation.

Further, SW2 is a card insertion completion detection switch, which detects by the movement of the detection lever 34 corresponding to the tilting at the card insertion completion position. Furthermore, SW3 is a shutter lock detection switch that detects the locked state of the shutter lever 28 in response to the movement of the shutter interlocking lever 30 that is linked to the opening/closing operation of the shutter lever 28.

FIG. 3 shows a control circuit block diagram of the composite card reader, in which the CPU 35 controls each circuit device according to the program stored in the ROM 36, and transfers the input/output data to the RAM 3.
Memorize in 7.

In particular, when processing data on a magnetic card, the CPU 35 uses the magnetic head 2 for the magnetic stripe of the magnetic card.
6. In order to stably process card data, the card insertion detection switch SW1 detects the insertion of a magnetic card and turns on the power, or turns on the power and the card data processing circuit of the magnetic head is fully activated. Card data processing is performed when the card is removed.

Thereby, data processing on the magnetic card can be performed in a stable circuit state.

The extraction indicator 38 is powered on when the card insertion detection switch SW1 detects insertion of the card during card data processing.
When the power is turned on and the data processing circuit of the magnetic card is completely activated, a message indicating that the magnetic card is to be removed is displayed externally.

The processing operation of the composite card reader configured as described above will be explained with reference to the flowchart of FIG. 4 and the time charts of FIGS. 5 and 6.

Normally, the card insertion slot 13 is in an open state where the shutter lever 28 moves upward to allow card insertion. When a customer inserts the card 12 into the card insertion slot 13 in this open state, the card insertion detection switch SW1 activates the card insertion detection switch SW1. The insertion of the card 12 is detected and the power is turned on (first to second steps 41 to 42).Furthermore, the tip of this card 12 comes into contact with the card receiving surface 22 of the slider 9 located inside the card passage 18. When this slider 9 is advanced against the urging force of the spring 21 and pushed until it comes into contact with the slider stopper surface 23 corresponding to the card processing position, the card insertion completion detection switch SW2 detects the card insertion completion position. At the same time, if the magnetic stripe is not detected at the time of insertion and it is determined that it is an IC card, the lock solenoid 31 is turned ON to process the IC card, and the rear end portion of the inserted card 12 is locked with the shutter lever 28. Lock the card (3rd to 5th steps 43 to 45).

Based on the shutter lock detection switch SW3 detecting this locked state, the contacts 25 are brought into contact with the IC contacts of the IC card to perform card data reading and writing processing.

In this case, in the locked state, data processing is performed with the power turned on and the card data processing circuit fully started up, so data processing can be performed under a stable circuit state (6th to 7th Steps 46-47).

When the data processing of this IC card is completed, the unlocking solenoid 32 is turned on to open the card insertion 1] 13, and the extraction indicator 38 indicates that the inserted IC

8-50).

Based on this sampling indication, cards are extracted.'/::
When the card insertion detection switch 1-3W1 detects this, the power is turned off and the IC card transaction ends (first
1-12th stage 51-, 52).

However, when the card is inserted, the card insertion completion detection switch SW2 detects that it is a magnetic card.
At 7', the IC card reaches the card insertion completion position.
4. After confirming that the magnetic card has been removed, the removal display 38 indicates that the magnetic card has been removed (Step 13). In the case of 14th step 54), at the time of removing the magnetic card, turn on the power.
! Since the data is processed with the card data processing circuit in a completely erected state, the data can be processed in a stable circuit state, and when the power card is removed,
When you pick up the filfT of the card with your fingertips and pull it out, the card can be removed and removed without wobbling, resulting in highly reliable data processing.

Then, when the card is pulled out, the above-mentioned 1- or 11-~
Similarly to Steps 1-2 51-52, the card insertion detection switch SW1 turns 0FFI to turn off the power, and the magnetic card transaction ends.

As mentioned above, the card 1': When the card is removed after the card has been inserted and the data processing circuit has started up.
The card data can be processed in a stable state of the circuit, and this data processing is linked to the insertion and removal of the card (1). Since it does not interfere with energy saving, data processing can be performed while saving energy.

As a result, it is possible to reliably downsize the C card reader by utilizing a small power source such as a battery.

In the correspondence between this invention and the structure of the above-mentioned embodiment, the reader corresponds to the composite cart handler 11 of the embodiment, and the card data processing section has a magnetic head. 26, the card detection means include a card insertion detection switch SW1, a card insertion completion detection switch SW2, and a shutter! 7 ivy detection switch SW3, and the power supply control stage 1 and data processing control means correspond to CI) U35; however, the present invention is not limited to the configuration of the embodiment described above.
