[Industrial applications]

 The present invention relates to a manual traveling type magnetic card reader.

[0002]

[Prior Art]

 By providing a read magnetic head for reading the information recorded on the magnetic card and a recording or read magnetic head capable of recording and reading the information in the card passage and manually running the magnetic card. A manual traveling magnetic card reader that reads and writes records has already been put to practical use. An example of such a magnetic card reader will be described with reference to FIG. In the card passage O that guides the magnetic card C, a reading magnetic head 41 and a recording or reading magnetic head 42 are arranged along the card running direction. The distance L between the magnetic heads 41 and 42 is set to be equal to or slightly larger than the length of the magnetic card C.

When reading or recording / reading the magnetic card C, as shown in FIG. 3, the magnetic card C held in the hand is inserted into the card passage O, and the lower edge Ca of the magnetic card C is inserted into the card passage O. The card is run in the card running direction a while being fitted to the guide surface Oa. The magnetic card C passing through each magnetic head can be pressed against the head surface by using an appropriate means.

[0004]

[Problems to be solved by the device]

 Regarding the jitter of the card when the magnetic recording of the magnetic card C is read by the reading magnetic head 41 and the jitter when the magnetic recording is performed by the recording or reading magnetic head 42, the latter is more severe. Imposed. Therefore, the mutual distance L between the magnetic heads 41 and 42 is set so that the card pressing force of the read magnetic head 41 does not reach the magnetic card C passing through the recording or read magnetic head 42. It is set equal to or longer than the length. In order to avoid the adverse effect of the magnetic head 41 on the jitter, the magnetic head 42 may be provided on the front side of the magnetic head 41 in the card running direction, but if the card passage O is not lengthened. There is a problem that does not happen.

That is, the relative position of the magnetic stripe with respect to the recording or reading magnetic head, in other words, the running posture and speed of the card must be substantially constant, but the posture and speed of the card with respect to the reading magnetic head are It's comparatively rough compared to that for use. Therefore, the recording or reading magnetic head 42 is arranged behind the reading magnetic head 41 in the region where the running posture of the magnetic card is stable. If the recording or reading magnetic head is arranged on the front side of the recording magnetic head 41 in the card running direction a, the card path length required to stabilize the running posture and speed of the card must be secured. However, there is a problem that the total length of the card reader becomes long. In particular, the total length of the manual magnetic card reader of the type built into the device has a significant meaning in terms of installation space within the device body.

Therefore, an object of the present invention is to provide a manually traveling type magnetic card reader capable of shortening the card path length without deteriorating the jitter.

[0007]

[Means for Solving the Problems]

 In the manual traveling type magnetic card reader of the present invention, the first magnetic head for reading and the second magnetic head for recording or recording / reading are respectively faced to the card passage, and the magnetic card is manually placed in the card passage. In a magnetic card reader for reading or recording information by pulling it through, the first magnetic head is arranged closer to the front side in the card traveling direction than the second magnetic head, and the first magnetic head is pressed against the magnetic card. The force is smaller than that of the second magnetic head.

[0008]

[Action]

 Since the magnetic card that can be run in the card passage has a small pressure contact force with the first magnetic head, the jitter when passing through the second magnetic head is small. Since the first magnetic head is arranged in front of the second magnetic head in the card traveling direction, the magnetic card to be transported is fed to the second magnetic head with its posture and speed being stable.

[0009]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.

In FIG. 1, reference numeral 1 generally indicates a manual traveling type magnetic card reader, and a card passage O formed in a groove shape in the card reader 1 is in the card traveling direction a from the front side. In order, a first magnetic head 2 for reading and a second magnetic head 3 for recording or reading face each other.

The first magnetic head 2 is projected into the card passage through a window hole 4 a formed in one side wall 4 of the card passage O. The head surface 2a of the first magnetic head 2 is opposed to the pad portion 2c provided in the card passage. The first magnetic head 2 is adhered to and supported by a head holder 2b made of a leaf spring material. The head holder 2b is fixed to the side wall 4 and urges the first magnetic head 2 in a direction to bring the head surface 2a into contact with the magnetic card C with a relatively small pressure contact force.

Between the pad portion 2c and the head surface 2a, the protrusion amount of the head is set so as to be smaller than the thickness of the magnetic card C, and when the card travels, the magnetic head 2 is attached to the head holder 2b. It is retreated against the elasticity of.

The second magnetic head 3 has its head surface 3 a projected into the card passage O from a window hole 5 a formed in the other side wall 5. A rotatable pad roller 6 facing the head surface 3a is projected from the window hole 4b of the side wall 4. The pad roller 6 is supported by a supporting shaft 6a. The second magnetic head 3 is adhered to and supported by the holding portion 7a of the head holder 7.

The head holder 7 is loosely fitted to the guide pins 9 a and 9 b fixedly planted on the substrate 8 and is movable back and forth with respect to the card passage O. A coil spring 11 is wound around a pin 10 which is loosely fitted in the substantially central portion of the head holder 7, and biases the head holder 7 toward the card passage O. The pressure contact force of the coil spring 11 with respect to the magnetic card of the second magnetic head 3 is set to be larger than that of the first magnetic head 2.

In FIG. 2A, arranging positions of the first and second magnetic heads 2 and 3 in the card passage O are OB and OC. The mutual distance L1 between the first magnetic head 2 and the second magnetic head 3 is shorter than the length of the magnetic card C. The card passage OA-OB between the card insertion slot OA and the position OB is a run-up section of the card in which the magnetic card C to be manually run is put on the bottom portion Oa of the card passage, and the magnetic card C is put on the second magnetic head 3. The card passage OC-OD between the position OC and the exit OD is a post-feed section for keeping the attitude of the magnetic card C with respect to the second magnetic head 3 constant. It is desirable that the length of the post-transmission section OC-OD be equal to or longer than half of the card length.

The operation of the embodiment configured as described above will be described with reference to FIG. Note that FIG. 2B shows changes in the traveling speed of the magnetic card in the card passage O.

In FIG. 2, the magnetic card C is grasped with a finger and inserted into the run-up section OA-OB of the card passage O, and the lower edge Ca of the card is brought into contact with the bottom portion Oa. Normally, the speed of the card is zero at this point. When the inserted magnetic card C is moved along the passage in the card traveling direction a, the speed thereof gradually increases in the approach section OA-OB. When this magnetic card C is sandwiched between the first magnetic head 2 and the pad portion 2c, the running speed is temporarily slowed down, but the pressure contact force of the first magnetic head 2 against the card is small, so it further rises. Can be run while.

The first magnetic head 2 is a read head, and the jitter limit is usually allowed up to about 40%. Therefore, even if the running speed of the card is increasing, if the jitter is within the limit, the recording can be read.

When the magnetic card C, which is manually run, further travels and reaches the position OC held by the second magnetic head 3 and the pad roller 6, the pressing force of the head on the card is large. After that, the second magnetic head 3 is moved at a substantially constant speed while receiving the running resistance by the second magnetic head 3.

The substantially constant speed in this case refers to a speed that does not significantly change. When a magnetic card is run manually, the card run in the approach path at the beginning of the card path is moved at a substantially constant speed within a distance of about the length of the card when it receives some running resistance.

In the magnetic recording by the second magnetic head 3, if the jitter is about 10% or less, the recording quality is generally acceptable. The running resistance by the first magnetic head 2 arranged on the front side in the running direction also acts on the magnetic card C running while receiving the recording operation by the second magnetic head 3. However, since the pressure contact force of the head 2 with respect to the card is smaller than that of the second magnetic head 3, the running resistance of the card passing through the position OC does not appear enough to reduce the speed.

If the pressure contact force of the first magnetic head 2 with respect to the card is large, when the card passes the position OC of the second magnetic head 3, a large running resistance due to the first magnetic head 2 is received. As shown by the broken line in FIG. 2 (b), the running speed drops significantly, and exceeds the allowable jitter amount during recording. In this respect, according to the present invention in which the pressure contact force of the first magnetic head 2 with respect to the card is set to be smaller than that of the second magnetic head 3, the running resistance by the first magnetic head is reduced even if the distance between the magnetic heads is shortened. Since it is small, the jitter when recording with the second magnetic head 3 is small, and the recording quality is improved.

[0023]

[Effect of the device]

 As described above, according to the present invention, since there is no adverse effect of the jitter at the time of recording information, even if the distance between the first and second magnetic heads arranged in the card path is shortened, the recording quality is improved. It is possible to go above. Also, shortening the distance between the magnetic heads means that the length of the card reader can be shortened.
