Description

The present invention relates to a card punching device, and more particularly to a card punching device that conveys and punches a card.

<Prior Art> For example, in a card reader / writer for reading or writing a card having an optical, electronic, physical, or other type of information storage means including a magnetic card having a magnetic stripe. In some cases, a punch unit for punching a card is further provided. Conventionally,
When punching a card in the card reader / writer, the position sensor detects that the card conveyed toward the punch unit has reached a predetermined position, and the position detection signal detects, for example, a DC motor as a conveying means. The punching operation is performed when the motor is stopped, that is, when the card is stopped by turning off the switch or applying the motor brake.

However, according to the above configuration, the card moves by a distance according to the inertia of the transporting means including the motor until the card stops after the drive control of the motor is turned off. During the movement of the card due to this inertia, since the card is out of control, the stop position of the card becomes random. In order to punch a card with high accuracy, it is preferable to perform the punching operation by using feedback control or the like, but there is a problem that the structure becomes complicated and the cost of the apparatus rises.

<Problems to be Solved by the Invention> In view of such problems of the conventional technology, a main object of the present invention is to provide a card punching device capable of punching a conveyed card with high accuracy by a simple structure. Especially.

[Structure of the Invention] <Means for Solving the Problem> According to the present invention, such an object has a carrying means for carrying a card between two positions and a punch unit for punching the card. A card punching device, comprising position detecting means for detecting that the card has passed a predetermined position, means for measuring a moving distance of the card from the predetermined position, and a moving distance of the card being a first predetermined distance. When reaching the value, the card is conveyed at a constant low speed lower than the speed before reaching the first predetermined value, and when the moving distance of the card reaches the second predetermined value, at the low speed. And a control means for actuating the punch unit to punch the moving card.

<Operation> By doing this, the card is punched when the distance at which the measurement is started from a predetermined position reaches a predetermined value while the card is being transported at a constant low speed, and therefore the transport control cannot be performed due to the process until the card stops due to inertia. Since there is no such area, it is possible to prevent the punching position from shifting for each card, and it is possible to perform a highly accurate punching operation.

<Embodiment> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a plan view showing a card carrier according to the present invention, and FIG. 2 is a sectional view taken along line II-II of FIG. The fixed casing 1 is flat and has a box shape which is long in the axial direction in the left-right direction in the figure, and its front and rear ends are open. At the front end of the casing 1 on the left side of the figure, a card slot 2 which may be a magnetic card, for example, is inserted toward the right side of the figure, so that an insertion opening 3 is provided which is expanded in a vertical direction in a tapered shape. . The card 2 inserted from the insertion port 3 passes between the inner surfaces of the upper frame 4 and the lower frame 5 of the casing 1 which face each other.

On the upper frame 4 side, front and rear carrying rollers 6 and 7 are arranged at predetermined intervals along the carrying direction of the card 2. The front transport roller 6 is rotatably and rotatably supported by one side wall portion 8 standing upright on the upper surface of the upper frame 4 and a bearing bracket 14 provided on the upper surface of the upper frame 4. The shaft 9 is fixed to the inner shaft end of the casing 1. The rear transport roller 7 is fixed to an intermediate portion of a rotary shaft 15 which is rotatably supported by both side wall portions 8.

Transmission pulleys 16 having the same diameter are fixed to the shaft ends of the rotary shafts 9 and 15 projecting outward from the upper side wall portion 8 in FIG. Both transport rollers 6 and 7 are configured to rotate integrally with each other via a transmission belt 17 that is wound around. A motor 11 is arranged in the middle of the upper surface of the upper frame 4, and a motor pulley 12 fixed to the motor shaft is provided.
And the drive pulley 1 fixed to the shaft end protruding outward from the other side wall portion 8 of the rotary shaft 15 of the rear transport roller 7.
A drive belt 13 is stretched between 0 and 0. The motor 11 drives the rear-side transport roller 7 as a belt and also drives the front-side transport roller 6.

Note that, as well shown in FIG. 2, below both of the conveying rollers 6 and 7 facing the inside of the casing 1 from the opening formed in the upper frame 4, the lower side is opposed to the opening formed in the lower frame 5. Driven rollers 18 that face the inside of the casing 1 are arranged. Each driven roller 18 is rotatably supported at its base end by a free end of a pressing spring 19 fixedly provided on the lower surface of the lower frame 5, and is pressed by the pressing spring 19 to the corresponding conveying rollers 6, 7. It is being urged towards a blast.

A punch unit 20 is arranged near the insertion port 3 side of the casing. The punch unit 20 has a well-known structure. For example, a punch assembly 20a including a punch member and a drive unit for driving the punch member is provided on the upper frame 4 side, and a die assembly 20b is fixed on the lower frame 5 side. There is. In the vicinity of the side of the punch unit 20 opposite to the insertion port 3 side, in order to detect the front end of the card 2 conveyed from the insertion port 3, for example, the light emitting element 21a fixed to the upper frame 4 and the lower portion. A position sensor 21 including a light receiving element 21b fixed to the frame 5 is provided.

At the rear end portion of the motor shaft of the motor 11 described above, for example, a slit disk 22 having a plurality of slits radially arranged in a disk body with an equal angular pitch is coaxially fixed, and is attached to the upper frame 4. Is provided with an encoder sensor 23 that is combined with the slit board 22,
The rotation angle of the motor 11 is measured by an encoder composed of both. Therefore, the motor 1
The moving distance of the card 2 corresponding to the rotation angle of 1 can be measured with high accuracy.

Next, the operation procedure of this embodiment will be described below with reference to the flow chart shown in FIG. 3 and the card transfer speed chart shown in FIG.

When the detection means (not shown) detects that the card 2 is inserted through the insertion opening 3, as shown in FIG.
In step ST1, the motor 11 is driven in the high speed mode, and the leading end of the card 2 is elastically held between the front transport roller 6 and the driven roller 18,
The card 2 is conveyed from left to right in FIG. At this time, as shown in FIG. 4, the card 2 is accelerated and conveyed at a predetermined high speed V1.

Next, in step ST2, when the position sensor 21 detects the front end of the card 2, the process proceeds to step ST3, and in step ST3, a pulse signal output corresponding to the slit from the encoder sensor 23 is not shown. Start counting in the control circuit. In step ST2, when the output of the position sensor 21 is off, step S
Returning to the previous stage of T2, step ST2 is repeated.

Then, in step ST4, a count number or count corresponding to the moving distance L1 of the card 2 as a predetermined first predetermined value is counted, and when the count is counted up, the process proceeds to step ST5, and in step ST5, the motor 11
The control is switched so that the card 2 is driven in the low speed mode, and as shown in FIG. 4, the card 2 is conveyed while being decelerated to a constant low speed V2.

While carrying the card 2 in the low speed mode, step ST6
At this time, counting up to a count number corresponding to the moving distance L2 that reaches the punching position of the card 2 as the second predetermined value,
When the count is up, the process proceeds to step ST7. In step ST7, the punch unit 20 is driven to perform the punching operation, and in step ST8, the driving of the motor 11 is stopped.

Therefore, since the punching operation is performed when the card 2 is conveyed at a constant low speed, the deviation of the punching position for each card can be suppressed as much as possible, and the card 2 is punched, for example, as a measure of the remaining amount of money or the remaining degree. In such a case, since it is possible to punch the position of the number printed on the card with high accuracy, the guideline becomes accurate, and it becomes possible to subdivide the guideline. After punching the card 2, the motor 11 is reversed to eject the card 2 from the insertion slot.

[Effects of the Invention] As described above, according to the present invention, the card is stopped because the punching operation is performed when the moving distance from the predetermined position reaches a predetermined value while stably transporting the card at a constant low speed. Since there is no uncontrollable area due to the process up to this point, it is possible to prevent the punching position from shifting from one card to another due to inertia and sliding resistance, etc. With a simple structure, it is easy to control the punching to a highly accurate position on the card. The effect is even greater because it can be performed at low cost.
