Abstract

PURPOSE:To eliminate the variance of the carrying speed to effectively use the overall area of a card format by pressing a card to a carrying belt at the time of taking in the card by a taking-in roll and releasing the pressing state at the time of arrival of the leading edge of the card at the position on a magnetic head and pressing the card to the carrying belt again at the time of returning the card. CONSTITUTION:When a card 7 is inserted from a card insertion/return slot 9 to a card taking-in passage 10, the driving signal from a control part drives a driving motor 26 based on detection signals of sensors S1 and S2, and a carrying belt 23 is run in the forward direction and a solenoid 24 is excited, and a taking-in roll 19a is raised to compress the leading edge part of the card 7 to a carrying roll 18a with the carrying belt 23 between them. When the card 7 reaches the position on a magnetic head 15, it is separated from the carrying roll 18a; and when it is ejected, it is compressed to the carrying roll 18a. Thus, the speed of the card 7 is prevented from being varied during the card processing of the magnetic head 15, and the overall area of the card format is effectively used.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a card reader for reading magnetic information recorded on a magnetic card such as a telephone card, writing information to the magnetic card, and confirming the information. Regarding the conveyance mechanism.

[Prior Art] In general, this type of card reader that reads magnetic information recorded on various magnetic cards such as telephone cards, and records and confirms information on magnetic cards is equipped with a card transport mechanism, By operating this with a drive motor, cards are taken in and processed. Such a card transport mechanism includes a transport roller and a take-in roller that are arranged opposite to each other across a transport path, a transport belt is stretched around the transport roller, and the take-in roller is pressed against the transport roller via the transport belt. The most common type of card is one in which the conveyance roller is rotationally driven, and the card is held between the take-in roller and the conveyance belt and conveyed.

[Problems to be Solved by the Invention] By the way, in order to reduce the size of conventional card leagues, the conveyance path is shortened, but this also shortens the overall length of the card conveyance mechanism itself. There was a problem in that the card would come off the roller, causing speed fluctuations in the card. Furthermore, since speed fluctuations cause failures in the reading and writing of magnetic information by the magnetic head, conventionally the recording section has been provided with a dead zone of several yns (about 4 mm to 5 m), that is, an area that is not read as data.

However, providing such a dead zone resulted in an insufficient amount of magnetic information, and there was also the problem that it was necessary to create a timing bit during card formatting to skip over the dead zone in the software. Therefore, the present invention has been made in view of these conventional problems, and its purpose is to eliminate fluctuations in conveyance speed with a relatively simple configuration and to make effective use of the entire card format. An object of the present invention is to provide a card transport mechanism for a card reader.

A take-in roller that is arranged to face each other so as to be able to be separated from each other; a spring that gives the take-in roller a return behavior in the direction of moving away from the transport roller; a sensor that detects a card; and a sensor that is driven based on a card detection signal from this sensor. a drive means for pressing the take-in roller against and away from the conveyance roller; the take-in roller is normally separated from the conveyance roller, and is operated by the drive means when taking in a card, so that the take-in roller is moved through the conveyance belt; The card is pressed against a conveyance roller, separated when the leading edge of the card reaches the magnetic head, and then pressed against the conveyance roller again by a driving means when the card is ejected. [Function] In the present invention, the take-in roller presses the card against the conveyor belt when taking in the card, releases the pressed state of the card when the leading edge of the card reaches the magnetic head, and presses the card against the conveyor belt again when returning the card. [Example] The present invention will be described in detail below based on an example shown in the drawings.

is pressed against the take-in roller 18a facing this, i
This is controlled by a solenoid 24, etc., which acts as a driving means for the time. The shafts 22a and 22b on the upper side of the transport path are provided with transport rollers 18a and 18b, respectively, and the shaft 22 on the rear side
One end of b protrudes to the outside of the base 1, and two worm wheels that mesh with a worm 28 provided on an output shaft 27 of a drive motor 26 are attached to the protruding end.

The drive motor 26 is fitted into a motor mounting portion 30 integrally provided on the right side surface of the base 1. Note that the shaft 22
b is located above the magnetic head 15, and the touch roller 16 is attached thereto.

Of the two shafts in Shimonoseki, the front shaft 22c is rotatably supported by a base l, and a l-th bracket 33 is fixed to one end of the shaft, and this l-th bracket 33 is connected to the Nrenoid. It is connected to 24 movable iron cores 31 via a connecting pin 32.

On the other hand, at the other end of the shaft 22c, a second bracket 35, which rotatably supports the shaft 34 of the take-in roller l9a, is disposed so as to be rotatable by a small angle in the vertical direction. This rotation angle is controlled by a bottle 36 driven into the shaft 22c in its radial direction, and a long hole formed in the second bracket 35 to be elongated in the card conveying direction, into which one end of the bottle 36 is inserted. 3
7. Further, a spring 38 is attached to the shaft 22c and urges the second bracket 35 in the counterclockwise direction in FIG. The central portion is locked to the bin 36 as shown in FIG.

The shaft 22c is given the habit of rotating clockwise in FIG. 1 by a return spring 40 whose one end is locked to the first bracket 33. : Depending on the
9a is retracted below the card processing conveyance path l1 and separated from the conveyance roller 18a. A shaft 22d on which the rear side take-in roller 19b is housed
is movable up and down with respect to the base 1, and is pressed against the conveyance roller 18b by a spring 44 via the conveyance belt 23.

The shutter mechanism 14 is located immediately after the card insertion/return slot 9 and normally opens the card take-in passage 10. When the card transport machine W413 takes in the card 7, the shutter mechanism 14 is operated to open the card take-in passage 10. It closes and prevents the insertion of a second card, and consists of a solenoid 45 (Fig. 2) arranged on the underside of the base 1, and a sheet buried in the underside of the cover 2 facing the solenoid 45. It is composed of a magnet 46. The movable core 47 of the solenoid 45 is normally located at the lowest position and opens the card intake passage 10. When the solenoid 45 is energized and excited, it is pulled up and held by the sheet magnet 46, and opens the card intake passage 10. Close 10.

The punch mechanism 17 includes a punch stand 50 and a solenoid 51 that are arranged vertically opposite to each other across the card receiving passage 0.
It is a well-known thing that is prohibited in the past, and at the end of the service,

are integrated. Next, a card processing operation in the card reader having such a configuration will be explained.

When the card 7 is not inserted, the shutter mechanism 14 opens the card intake passage 10, the drive motor 26 is stopped, and the solenoid 24 is in a non-energized state. At this time,
The take-in roller 19a is separated from the conveyance roller 18a by the force of the return spring 40, and is retracted below the card processing conveyance path 1l. In this state, when the card 7 is inserted into the card take-in passage 10 from the card insertion/return slot 9 and its tip reaches the sensor S2, both the sensors S1 and 82 are turned on, and based on the detection signal, the control section The drive signal drives the drive motor 26, causes the conveyor belt 23 to run in the forward direction, that is, in the card storage direction, and at the same time excites the solenoid 24. Then, the movable iron core 3
1 is attracted to the right in FIG. 1 and rotates the first bracket 33 counterclockwise against the return spring 40. When the ↓-th bracket 33 rotates, the shaft 22c rotates together with it to raise the take-in roller 19a and press the leading end of the card 7 to the conveyance roller 18a via the conveyance belt 23.

At this time, the drive motor 26 drives the card 7 to start taking in the card 7, and the take-in roller 19a presses the card 7 at almost the same time, so there is no risk that the speed of the card 7 will fluctuate, and even if it does, the magnetic There is no problem since the head 5 has not yet started reading information. The card 7 is taken in by the force transfer mechanism l3 by pressure contact by the take-in roller 19a, and the card 7 is transferred to card processing transfer #11l.
When it is conveyed along the magnetic head l5 and the touch roller l6, its leading end is inserted a certain distance between the magnetic head l5 and the touch roller l6, and its rear end is removed from the sensor S1. Therefore, the sensor St returns to OFF, and based on the signal, the energization to the solenoid 24 is stopped.
Return to de-energized state. Therefore, the No. 1 bracket 33 is released from the solenoid 24 and returns to rotation by the action of the return spring 40, moving the take-in roller 19a to the transport roller 18.
It is moved away from a and retracted to the initial position.

On the other hand, since the drive motor 26 continues to be driven, the card 7 is further advanced, and when it has advanced a certain distance (several mm), the magnetic head 15 starts reading the magnetic information. When the take-in roller 19a separates from the transport roller 18a, a speed change occurs in the card 7, but at this time, the card 7 is held between the rear-open transport roller 18b, the take-in roller 19b, the magnetic head 15, and the touch roller 6. Therefore, there is no speed variation and there is no adverse effect on reading. After the magnetic head l5 has finished reading the information, the leading edge of the card 7 reaches the sensor S3 and is turned off.
When set to N, the rotation direction of the drive motor 26 is switched and the card 7 is sent back along the original path. At this time, information is written to the card 7 by the magnetic head 15.

During this writing, since the rear end of the card 7 is held between the rear transport roller 18b, the take-in roller 19b, the magnetic head 15, and the touch roller 6, there is no speed fluctuation and no adverse effect on the writing. Never.

When the card 7 is fed backwards, its leading edge comes off the magnetic head 15, and its trailing edge is detected by the sensor S1, the rotation direction of the drive motor 26 is switched back to the forward direction based on the detection signal from the sensor S1, and the card 7 is rotated in the forward direction. Check the data written in 7. At this time, the solenoid 24 is energized,
The take-in roller 19a is connected to the conveyor roller 18a by a conveyor belt.
23 and the card 7. At the moment of pressure contact,
Although speed fluctuations occur in the force drive 7, at this time, the data has not yet been confirmed by the magnetic head 15, so there is no problem. When normal recording of data is confirmed, the rotation direction of the drive motor 26 is switched and the card insertion/return slot 9 is opened.
Return it to. During this return operation, the card 7 is inserted between the take-in roller 19a and the conveyor belt 23, which causes speed fluctuations, but at this time, the magnetic head 15 has completed reading, writing, and confirming the data. Therefore, there will be no adverse effects. If the balance information remains, a small hole is punched by the punch W417, and then the card is discharged and returned from the card insertion/return slot 9.

[Effects of the Invention] As explained above, according to the card conveyance mechanism of the card reader according to the present invention, the drive means drives the take-in roller disposed opposite the conveyance roller located in front of the magnetic head to take the card. The structure is such that the card is pressed against the magnetic head when it is inserted, separated from the conveyance roller when it reaches the top of the magnetic head, and pressed against the conveyance roller when it is ejected, thereby preventing fluctuations in the speed of the card while the card is being processed by the magnetic head. can. Therefore, there is no need to provide a dead zone on the card, and the entire card format can be used effectively.
