Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card reader having a structure in which a card transport path is formed between upper and lower units of a machine to open and close units on the machine.

[0002]

2. Description of the Related Art A conventional magnetic card reader generally has a structure as shown in FIGS.

[0003] The structure will be described below with reference to FIGS. 5 and 6. As shown in the figure, a card insertion slot 31 for inserting a magnetic card is formed at the front end (left end in the figure) of the machine, and a card transport path extends from the card insertion port 31 toward the rear end of the machine. A card stopper 32 is formed at the end of the card transport path.
The sensor 35, the motor 3
3. Conveying roller 3 driven via speed reduction unit 36 by
4 and a magnetic head 37 are arranged. 3 in the figure
8 is an encoder slit attached to the motor shaft, 3
9 is a photo interrupter corresponding to the encoder slit 38, and 40 is a worm gear.

In the above configuration, when the sensor 35 detects a card inserted from the card insertion slot 31, the motor 33 starts to rotate at a predetermined number of rotations, and the speed is reduced by a reduction section 36 composed of a worm gear 40 to drive the transport roller 34. I do. When the card inserted by hand reaches the transport roller 34, the card is automatically transported by the transport roller 34, and magnetic data is read and written on a magnetic track of the card as the card passes while contacting the magnetic head 37. Will be

When reading and writing magnetic data with the magnetic head 37, the following two points are important.

(1) The magnetic card is transported at a constant speed. (2) The data writing is performed at a constant interval. This is because the read output from the magnetic head also fluctuates greatly due to its nature, and a read error occurs.

The reason (2) is that if the recording of magnetic data is not performed at a constant interval, the 1/0 determination of the data at the time of reproduction will be erroneous and a reading error will occur. That's why.

In order to prevent these problems, the rotation speed of the motor is feedback-controlled (servo-controlled) so that the speed does not fluctuate even if the transport load fluctuates. At this time, an encoder unit for obtaining rotation information of the motor is required. In this machine, an encoder slit 38 attached to the motor shaft is detected by a photo interrupter 39, and a signal from there is used. Speed control.

By writing data to the card at a timing synchronized with the signal of the encoder,
Magnetic data recording can always be performed at regular intervals.

By the way, the following two items that are most likely to cause problems in operating the magnetic card reader / writer are caused by contamination inside the card transport path due to long-term use.

(1) If dirt or dust is present between the magnetic head 37 and the magnetic recording portion of the card, data cannot be recorded / reproduced correctly and an error may occur.

(2) If the transport roller 34 becomes dirty, the transport of the card may slip and jam.

In most of the previous magnetic card reader / writers, the card transport path is sealed, and when the above-mentioned problem occurs, a countermeasure (for removing the internal card,
Cleaning the magnetic head and transport rollers) requires disassembly of the device, which is very time-consuming.

In recent years, as a countermeasure, a magnetic card reader having a structure in which the body can be opened and closed with one touch and a card transport path can be exposed has been devised. The outline will be described with reference to FIG.

In this magnetic card reader, an upper body unit 51 and a lower body unit 52 are rotatably connected by a rotation fulcrum 53 provided at an end opposite to the card insertion slot 31 as shown in the figure. A lock claw 54 is provided on the upper body unit 51, and the lower body unit 52 is provided with a lock claw 54.
Normally, the card transport path is maintained in a closed state.

Since the lock claw 54 is made of an elastic resin, the knob 5 of the lock claw 54 is used.
By pressing the finger 6 with the finger, the lock claw 54 and the lock hole 55 are released from the engaged state, and the card transport path can be exposed by lifting the body unit 51 with the finger as it is.

With the above-described structure, the card transport path can be easily exposed without disassembling the machine body. Therefore, when the card is jammed inside due to jamming, or when the magnetic head and transport rollers are cleaned, It became very easy to respond.

[0018]

As described above, the material of these structures is such that the lock claws 54 have elasticity (usually resin). However, if these parts are made by resin molding widely used in the general public, the card insertion opening 31 may be opened as shown in FIG. 8 due to partial deformation or warpage. This is because the position of the lock claw 54 is located right beside the transport roller in order to ensure the transport of the card, so that there is no pressing near the card insertion slot 31.

In such a case, in addition to the unsightly appearance, in a severe case, the magnetic card to be inserted is caught in a gap formed by deformation and jammed. In addition, if an attempt is made to provide a function of preventing the double insertion of a card, which is one of the functions of a magnetic card reader / writer, dimensional accuracy cannot be ensured only by providing ribs on the body vertical unit in order to regulate the card thickness. There is a drawback that the card insertion prevention member 57 is required.

That is, if a card is inserted into a card reader / writer in a state where two cards are stacked, a trouble such as the card being jammed inside the machine occurs. Therefore, the card double insertion prevention member 57 is larger than the thickness of one card, and It has a slit smaller in thickness than the thickness, is provided near the card insertion slot, and has a function of preventing double insertion.

The present invention takes into account the above-mentioned conventional problems, and prevents problems such as poor appearance and card jam due to a gap between the upper and lower units of the machine, and two parts of the upper and lower units of the machine without adding a separate slit-shaped part. It is an object of the present invention to provide a card reader that can achieve the function of preventing double-ply cards only by using the card reader.

[0022]

In order to achieve the above object, the present invention provides a card transport path between a vertical unit of a machine, a transport roller in the card transport path, and a card for reading or writing card data. A card reader having means for performing at least one of them is provided, in which an onboard unit is slid back and forth, and then rotated and opened to expose a card transport path.

According to the present invention, defects such as poor appearance and card jam due to a gap between the upper and lower units of the machine are prevented, and two cards are stacked only by the two units of the upper and lower units without adding a separate slit-shaped part. The prevention function can be achieved.

[0024]

According to the first aspect of the present invention, a card transport path is provided between an upper unit and a lower unit of an airframe, and a transport roller and a card data are read in the transport path. Or a card reader having means for performing at least one of writing, wherein the card reader is such that the upper unit is slid back and forth and then rotated to open and close to expose the transport path, and the gap between the upper and lower units It has the effect of preventing defects such as poor appearance and card jam due to the above.

According to a second aspect of the present invention, in the card reader according to the first aspect, two cards are inserted near the card insertion opening formed between the front ends of the upper unit and the lower unit. The rib has a function of preventing a double card stacking function with only two components of the body vertical unit without adding a separate slit-shaped part.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. (Embodiment 1) FIG. 1 is a side view showing an internal body of a card reader according to Embodiment 1 of the present invention, FIG. 2 is a top view of the internal body, and FIG. 3 is a view for explaining opening and closing of the aircraft. FIGS. 4A and 4B are explanatory views of the double-sheet insertion preventing function in the airframe.

2 is a card stopper at the rear end of the machine, 3 is a motor, 4 is a transport roller, 5 is a sensor, 6 is a deceleration unit, 7 is means for recording data on or reading data from the card. And

Reference numeral 9 denotes a photo interrupter, reference numeral 12 denotes a worm gear, and reference numeral 13 denotes an encoder slit. These components are configured in the same manner as in the above-described conventional example, and the description thereof will be omitted.

When the sensor 5 detects a card inserted from the card insertion slot 1, the motor 3 starts rotating at a predetermined number of rotations, and the speed reduction unit 6 reduces the number of rotations to rotate the transport roller 4; When the inserted card reaches the transport roller 4, the card is automatically transported, and the magnetic head 7
The operation of reading and writing magnetic data on the magnetic track of the card when passing while contacting the card, and the operation of controlling the card transport speed and recording magnetic data at the encoder unit are the same as those in the conventional example.

Further, in order to simplify the maintenance of the equipment, the body is composed of an upper body unit 21 and a lower body unit 22, and the upper body unit 21 is opened and closed, and the card transport path between the upper and lower units 21 and 22 can be exposed. The same applies to the structure.

The first embodiment is characterized by the method of engaging the body vertical units 21 and 22 and the procedure for opening and closing the units.

FIGS. 3A and 3B show a normal card processing.
This is the state shown in FIG. At this time, the front hook indicated by R engages with the L-shaped hook 23 of the upper body unit 21 and the receiving portion 24 of the lower body unit 22, and
1 and 22 are in close contact with no gap. Also,
The lock portion indicated by M is a lock claw 2 of the on-body unit 21.

In the first embodiment, the lock claw 25 is mounted in the horizontal direction in order to make the height of the machine body as low as possible.

When exposing the card transport path, first, the lock claw 25 of the M section is changed from the state shown in FIGS.
Is pressed inward with a finger to release the lock claw 25 and release the lock. Next, the body upper unit 21 is slid rightward in FIG. 3 while the lock claw 25 is being pressed inward with a finger, and the state shown in FIGS. 3D and 3E is obtained. At this time, the rotation fulcrum 27 of the upper body unit 21 indicated by N moves from the left side to the right side of the double hole 28 of the lower body unit 22.

At this time, the R unit hook is disengaged from the body vertical units 21 and 22, and if lifted as it is, the body upper unit 21 rotates and the card transport path is exposed as shown in FIG. 3 (f). Become like

With the above configuration, the card transport path can be easily exposed without disassembling the machine body by using a tool or the like. In addition, it is very easy to cope with the cleaning of the transport roller.

Further, since there is no gap near the card insertion openings of the body vertical units 21 and 22 due to the hooks of the R portions, the card 29 is simply provided in each of the body vertical units 21 and 22 as shown in FIG. It is possible to accurately realize the distance A between the ribs, which can prevent the double-ply insertion.

The vicinity of the center of the double hole 28 in the N section of the lower body unit 22 is slightly smaller than the diameter of the fulcrum shaft of the upper body unit 21 so that
When the user slides 1 forward and backward, a click feeling is generated, and the position of the on-body unit 21 is surely moved without stopping. Also, the lock claw 2 of the M section
Since the on-body unit 21 is slidable only after the release of 5, the on-body unit 21 does not accidentally move due to vibration during transportation, mischief from the card insertion slot, or the like. Conversely, even when the upper body unit 21 is closed after maintenance is performed, by confirming that the lock claw 25 of the M portion is engaged, the upper and lower units 21 and 22 can be reliably positioned without displacement.

[0039]

As is apparent from the above description,
