Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a supply path shutter so as to be opened and closed in a direction perpendicular to the recording medium supply path, and a combination of the supply path shutter and the discharge path switching plate. This invention relates to a shutter mechanism of an interlocked card reader.

[Conventional technology]

FIG. 3 shows a schematic configuration of a card reader. A card-shaped recording medium 2 supplied from a recording medium supply path 1 is sent to a belt conveyance mechanism 3, and this conveyance mechanism 3 leads to a reading unit equipped with a magnetic head. The data is read.

Further, the recording medium 2 after reading the data is discharged to the outside through a recording medium discharge path provided separately.

A supply path shutter 4 is provided in the recording medium supply path 1 to prevent double insertion of the recording medium 2 and the like. The supply path shutter 4 is rotatably supported on a pivot shaft 5 provided near the recording medium supply path 1, and opens and closes the supply path 1 by its rotational action.

[Problem that the invention attempts to solve]

In the conventional shutter mechanism configured as described above, since the supply path shutter 4 is rotatably provided, when opening and closing the recording medium supply path 1, it becomes parallel to the medium movement direction of the supply path 1. It has a working part in the direction. Therefore, if the recording medium 2 is accidentally inserted with strong force when the supply path shutter 4 is in the closed position, the supply path shutter 4
There was a risk that the opening operation would occur due to the insertion force and the recording medium 2 would be inserted incorrectly. Furthermore, if the recording medium 2 is inserted with more than a certain force when the supply path shutter 4 is about to open, the supply path shutter 4 will open while pushing back the recording medium 2. The opening operation of the
There was also a risk that problems would arise, such as having to use a large power source as a drive source for opening and closing the supply path shutter 4.

The present invention was developed to solve these problems, and its purpose is to reliably prevent incorrect insertion of card-shaped recording media, and to reliably open and close the supply path shutter with a light force. It is an object of the present invention to provide a shutter mechanism for a card reader in which a supply path shutter and a conveyance path switching plate are interlocked with each other by a simple structure.

[Means for solving problems]

In order to achieve the above object, the present invention includes a recording medium supply path for supplying a card-shaped recording medium and a recording medium ejection path for discharging the recording medium to the outside, which are connected to the recording medium transport path and branched from each other. In the card reader provided as described above, a supply path shutter is provided in the recording medium supply path so as to be movable in a direction orthogonal to the supply path, and opens and closes the supply path by advancing and retreating; When the conveyance path switching plate is rotatably provided between the medium discharge path and switches the recording medium conveyance path by its rotation operation, and the supply path shutter is in a position to open the recording medium supply path. When the conveyance path switching plate is in the position to close the recording medium ejection path and the supply path shutter is in the position to close the recording medium supply path, the conveyance path switching plate is in the position to open the recording medium ejection path. Features.

[Effect]

The supply path shutter is provided so that it can move forward and backward in a direction perpendicular to the recording medium supply path, so even if a recording medium is incorrectly inserted while the supply path shutter is in the closed position, the supply path shutter will not prevent recording. It will not open due to the insertion force of the medium. Furthermore, even if a recording medium is pressed against the supply path shutter when the supply path shutter is about to open, the opening operation of the supply path shutter will not be hindered by the insertion force of the recording medium, and the supply path shutter will open. Can be opened and closed with light force. Also,
Since the supply path shutter and the conveyance path switching plate are directly connected, the mechanism for interlocking them is simplified.

〔Example〕

An embodiment of the present invention is shown in FIGS. 1 and 2.

In the figure, 11' is a belt conveyance mechanism provided inside the card reader, and this conveyance mechanism 11 is
The card-shaped recording medium 14 is configured to be held between a pair of upper and lower endless belts 13a and 13b wound around guide rollers 12a, 12b, and so on, and conveyed by the rotation of both belts 13a and 13b. .

The upper endless belt 13a is wound around three guide rollers 12a, but these guide rollers 12a are not arranged in a straight line. On the other hand, the lower endless belt 13b has three guide rollers 12b arranged in a straight line...
The guide rollers 12a and 12b located at the front end are vertically spaced apart from each other, and the guide rollers 12a and 12b at the center and rear end are pressed against each other by elastic force.

A conveyance path switching plate 15 is rotatably provided between guide rollers 12a and 12b located at the front end. In the figure, reference numeral 16 denotes a pivot shaft that pivots the conveyance path switching plate 15. A recording medium supply path 17 is defined between the transport path switching plate 15 and the upper endless belt 12a, and a recording medium discharge path 18 is defined between the transport path switching plate 15 and the lower endless belt 12b. The recording medium supply path 17 and the recording medium discharge path 18 are formed by central guide rollers 12a and 12.
The recording medium conveying path 19 between the guide rollers 12a and 12b at the rear end is continuous with the recording medium transport path 19, and the positional relationship is such that they diverge from each other.

A supply path shutter 20 is provided in the recording medium supply path 17 so as to be movable forward and backward in a direction perpendicular to the supply path 17.
It is designed to open and close. Further, the conveyance path switching plate 15 opens and closes the recording medium discharge path 18 by its rotational operation.

The lower end of the supply path shutter 20 and the conveyance path switching plate 1
The front ends of the holes 21 and the protrusions 22 are engaged with each other by fitting into the holes 21 and the protrusions 22, respectively. And the supply path shutter 20
is in the position to open the recording medium supply path 17, the conveyance path switching plate 15 is in the position to close the recording medium discharge path 18 (FIG. 1), and the supply path shutter 20 is in the position to close the recording medium discharge path 18.
is in a position to close the recording medium supply path 17, and the transport path switching plate 15 is in a position to open the recording medium discharge path 18 (FIG. 2). The transport path switching plate 15 and the supply path shutter 20 are driven to open and close by a solenoid 23. When the recording medium 14 is not inserted, the supply path shutter 20 is in the closed position, and when the recording medium 14 is inserted, the supply path shutter 20 is opened and closed. The road shutter 20 is switched to the open position.

Therefore, when the recording medium 14 is inserted from the supply path 17, the recording medium 14 is sent to the reading section through the recording medium transport path 19. And recording medium 1
After the data No. 4 is read by the reading unit, the belt conveyance mechanism 11 is reversed, and the recording medium 14 is discharged to the outside through the recording medium discharge path 18.

Here, if an attempt is made to insert the recording medium 14 when the supply path shutter 20 is in the closed position, the supply path shutter 20 is provided so as to be able to move forward and backward in a direction perpendicular to the recording medium supply path 17, Even if the recording medium 14 is strongly pressed against the shutter 20, the shutter 20 does not open, and erroneous insertion is reliably prevented. Also, when the supply path shutter 20 is about to open, the recording medium 1
4 is incorrectly inserted and the recording medium 14 is strongly pressed against the supply path shutter 20, the opening operation direction of the supply path shutter 20 is perpendicular to the direction in which the recording medium 14 is inserted, so the supply path shutter will not close. The opening operation of 20 is not hindered. Therefore, the driving force for opening and closing the supply path shutter 20 can be reduced.
