DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus for recording or reproducing information on a discontinuous magnetic recording medium such as a magnetic card.

[0002]

2. Description of the Related Art Conventionally, in a magnetic recording / reproducing apparatus of this kind, a discontinuous magnetic recording / reproducing medium (hereinafter, referred to as a magnetic card) is used.
As one of the methods for transporting the “magnetic medium”, as shown in FIG.
The magnetic card which has entered from the direction has a magnetic head comprising magnetic recording / reproducing elements 1, 2 and the like which are smaller than the thickness of the magnetic medium due to the contact pressure between the rubber belts 3 and 4 and the frictional force between these rubber belts and the card-shaped magnetic medium. The rubber rollers 7a and 7b are conveyed to the gap between the magnetic head and the magnetic head, and the rubber rollers 7a and 7b slide with the magnetic head at a predetermined relative speed to transmit and receive information. And the frictional force between the rubber belts 3 and 4 and the magnetic medium is discharged in the direction of arrow B. Reference numerals 6, 9, and 10 denote driving pulleys of the rubber belts 3, 4, and 5, respectively.

[0003]

However, in the above-described conventional example, as represented by an automatic ticket gate at a station, for example, the magnetic card is driven at a high speed regardless of the front and back of the inserted magnetic card. It is necessary to send and receive data, and each has the following problems. That is, (1) In order to perform high-speed processing, it is necessary to convey a magnetic medium at a high speed, and it is necessary to lengthen a traveling path of a magnetic card. There were restrictions.

(2) When this apparatus is used as an apparatus for evaluating a magnetic head or the like, magnetic media must be manually loaded one by one, which takes much time for evaluation. Further, even when a durability test of a magnetic head or the like is performed, 1
There is a drawback in that it has to be manually inserted one by one, and the evaluation man-hour is greatly increased.

[0005] (3) When the magnetic layer surface faces downward due to random insertion of the front and back of the magnetic card, the sliding surface of the recording / reproducing element of the transmitting / receiving magnetic head faces upward, and dust generated inside the apparatus or dust brought in from the outside. Liable to accumulate, causing data errors.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described aspects, and can reduce the overall length of a magnetic card medium traveling system, and can automatically perform data retransmission / reception any number of times. It is an object of the present invention to provide a magnetic recording / reproducing apparatus of this kind which can be formed and does not cause accumulation of dust or the like on a sliding surface of a transmitting / receiving element.

[0007]

For this reason, according to the present invention, a card-shaped magnetic recording / reproducing medium is conveyed and the medium is conveyed.
A magnetic recording and reproducing apparatus for receiving and transmitting the information with respect to, at least one or more loop-shaped conveyor belt, comprising a guide plate including a roller on an outer periphery of the belt, along its belt outer periphery The medium rotates one or more turns, and when the medium is ejected, the medium has a switching mechanism for detecting the position of the medium and opening and closing a switch, and a magnetic recording / reproducing apparatus for recording / reproducing information on the front and back of the medium. The object is achieved by configuring the sliding surfaces of the elements so as to be arranged in the same downward direction.

[0008]

According to the construction of the present invention as described above, the traveling of the card-shaped magnetic recording / reproducing medium is of a rotary type, a continuous belt is provided inside the rotary, and a guide roller is provided on the outer peripheral side of the belt. As a result, the overall length of the apparatus of the traveling system is shortened, and when the magnetic card medium is discharged, a switch for switching the medium traveling path is provided, so that the magnetic card medium can be transported stably.
The re-transmission process can be performed any number of times,
All the magnetic heads such as the magnetic recording / reproducing elements used for transmission / reception to / from the magnetic card medium can be disposed downward to prevent accumulation of dust and the like.

[0009]

FIG. 1 is a side view of an embodiment of a magnetic card transport mechanism according to the present invention. In the figure, 1 is each magnetic recording / reproducing element for receiving / transmitting when the magnetic layer of the card is inserted downward, and 2 is each transmitting / receiving element when the magnetic layer of the card is inserted upward. is there. Reference numeral 3 denotes an endless main rubber belt for running the magnetic card in a loop shape. Reference numerals 4 and 5 denote respective rubber belts for pressing and conveying the card in opposition to the main rubber belt 3, and 6 for rotating the main rubber belt 3. This is a main belt drive pulley for causing the main belt to pull.

Reference numerals 7a and 7b denote transmitting / receiving elements 1 and 2, respectively.
Each main rubber roller for pressing and conveying the card to each element in opposition to 2, a switch for discharging the card after the completion of data transmission / reception, and a switch for rotating each rubber belt 4, 5 Drive pulleys 11 and 12
Is a pair of guide plates for smoothly changing the running direction of the card, and 13 is a rotating roller.

Here, when the magnetic card is inserted in the direction of arrow A, it is conveyed by the rubber belts 3 and 4 between the transmitting / receiving element 2 and the main rubber roller 7b, and receives / transmits data as necessary. 8, the card is conveyed upward in the figure by the main rubber belt 3 and the roller 13 along the guide plate 11, and is conveyed between the transmission / reception element 1 and the main rubber roller 7a by the rubber belts 3 and 5, if necessary. The data is transmitted and received by the main rubber belt 3 and the rollers 13 along the guide plate 12, and the switch 8 is moved upward by the card passage identification sensor 14 as shown by a two-dot chain line. And discharges in the direction of arrow B passing between the element 2 and the main rubber roller 7b.

At this time, if accurate transmission / reception is not performed due to troubles of the transmission / reception elements 1 and 2, the traveling system, the magnetic card, and the like, the switch 8 is processed again in the same loop without being switched upward. And the card can be re-received and transmitted without re-inserting the card. In addition, by making the card traveling path from a straight line to a loop, the total length (L1) of the traveling section can be made much larger than the conventional total length (L2 in FIG. 2). The main rubber belt 3 continuously participates in the card running in the loop, so that stable running can be obtained, and the sliding surfaces of the transmitting and receiving elements 1 and 2 are all arranged in the same downward direction. Therefore, the accumulation of dust and the like on the sliding surface can be prevented.

(Other Embodiments) The number of receiving and transmitting elements 1 and 2 is as follows.
Any number of one or more may be used. The driving stability of the rubber rollers 7a and 7b is better if a driving force is applied.

The number of rubber belts other than the main rubber belt 3 may be any number as long as it is one or more. Further, the main rubber belt 3 may have a plurality of belts as long as they have the same locus shape.

[0015]

As described above, according to the present invention,
A magnetic card medium is conveyed all around the rubber belt forming one loop, and a rubber belt and a guide roller for holding the magnetic card medium are arranged around the outer periphery of the belt, and one switch for switching whether or not the magnetic card medium can be ejected is provided. By forming the loop-shaped magnetic card medium traveling system having the above, the overall length of the transport mechanism can be greatly reduced, and data can be automatically re-received and transmitted any number of times. Since the dedicated receiving / transmitting element can be arranged in the same downward direction, there is an effect that the accumulation of rubber on the sliding surface of the receiving / transmitting element can be prevented.
