Description

[Detailed description of the invention] This invention is a card reader that reads data on the card surface while moving the card in one direction, with data recorded on the card surface by perforations or marks. The present invention relates to a card picker device for a card reader that transfers the card to a reading section.

Conventionally, a device for taking out stacked cards in the above-mentioned card reader has a structure as shown in FIG. 4, for example. That is, a shaft 52 is attached to a support base 51 that is rotatable around a shaft 50.
A support plate 53 is supported rotatably around the support plate 53, and a shaft 54 is rotatably supported at the tip of the support plate 53, and picker rollers 55 and 56 are separately supported at the upper end of the shaft 52, and both shafts are supported rotatably. 52 and 54 are connected via a belt 57, and a pulley 58 fixed to the shaft 52 and a drive pulley 59 connected to a drive source are connected by a belt 6.
An idler pulley 61 was provided so that the belt 60 was connected to the idler pulley 61 via a belt 60. In such a configuration, the support base 51 is rotated by energizing and deenergizing the electromagnet 62 in order to move the picker rollers 55 and 56 toward and away from the bottom card surface of the stacked card group. is displaced between the position 58 shown by the broken line and the position 58' shown by the chain line depending on the rotational position of This may cause accidents such as falling out or being cut.

This invention aims to eliminate the drawbacks of the above-mentioned conventional ones.

An example of this invention will be explained with reference to the drawings: 1
A drive shaft is rotatably supported on the machine frame in conjunction with a motor (not shown) through gears, etc., and a drive pulley 2 is fixed to the upper end.

Reference numeral 3 designates an operating shaft rotatably supported on the machine frame parallel to the drive shaft 1, and an operating pulley 4 with a timing belt A stretched between it and the pulley 2 on the upper stage is fixed to the lower end of the operating shaft. A driven pulley 5 on which an endless belt B (described later) is stretched is fixed at the lower end, and a presser roller 6 is mounted at the upper end to hold the card P (Fig. 1) in front of the reading section (not shown).
fixes the feed roller 7 that is pressed against it.

8 is a support shaft fixed to the machine frame parallel to the drive shaft 1, and 9 is a plate-shaped support stand rotatably supported on the support shaft 8.

Reference numeral 10 denotes an operating shaft which is rotatably supported through the support stand 9 parallel to the support shaft 7 which is disposed in front of the card movement path than the actuation shaft 3, and 11 is an action shaft which is spaced apart above the support stand 9 and has its base end connected 10 is a flat plate-like action plate rotatably supported; 12 is an action shaft 1 at the tip of the action plate 11;
The upper ends of the operating shaft 10 and the support shaft 12 are provided with picker rollers 13 and 14, the outer periphery of which faces the card surface at the lower end of the stacked card group. Fix separately and support shaft 1
A pulley 15 is fixed to the lower end of the working shaft 10.
A pulley 16 for passing an endless belt C between the pulley 15 of the support shaft 12 at the upper stage is fixed at the lower end (below the support base 9), and a belt B for passing the endless belt C between the pulley 5 of the operating shaft 3 at the lower stage. The interlocking pulley 17 that crosses is fixed. Reference numeral 18 denotes a support stand 9 parallel to the support shaft 8 and on the opposite side of the action shaft 10 with the support shaft 8 in between.
19 is an auxiliary pulley rotatably supported on the support shaft 18, and the auxiliary pulley 19 engages with the inside of the belt B that is passed between the driven pulley 5 and the interlocking pulley 17. Apply tension to.

Reference numeral 20 denotes an electromagnet connected to the support base 9. When energized, the support base 9 is pulled to rotate counterclockwise in Figure 2 to the active position (Figure 3), and when deenergized, it is rotated clockwise in Figure 3. It is configured so that it rotates and returns to the inactive position (Fig. 2).

The action plate 11 always receives an elastic force in the direction of bringing the tip closer to the card stacking side, and when the support base 9 is in the inactive position, both picker rollers 13 and 14 at the tip
It has a locking means (not shown) so that the outer periphery of the picker roller 14 is located at a close position (FIG. 2) slightly separated from the bottom card surface, and when the support stand 9 is in the operating position, the picker roller 14 is The outer periphery first contacts the card surface and is then pushed by the card surface, causing the action plate to move to the second
The transfer position where the outer periphery of the picker roller 13 at the proximal end faces the card moving path and both rollers 13 and 14 are in contact with the card surface (see Fig. 3) is rotated slightly clockwise in the figure against the elastic force. ). Note that belts B and C may be round belts or flat belts.

This invention has the above-mentioned configuration, and the drive pulley 2 rotates when driven by the motor, and the operating shaft 3 rotates via the timing belt A.
The operating shaft 10 rotates via the belt B that is passed around the driven pulley 4 on the coaxial 3, and the pulley 16 on the coaxial 10 rotates, and the belt C passes through the supporting shaft 12.
rotates. As a result, the picker roller 13,
14 rotates, but when the electromagnet 20 is deenergized and the action plate 11 is in the close position (Fig. 2), both picker rollers 13 and 14 are away from the card surface, so the card is not taken out. .

When the electromagnet 20 is energized, it pulls the support stand 9, and the support stand 9 rotates counterclockwise toward the operating position. As a result, the picker roller 14 first comes into contact with the card surface and presses it against the card surface. Pushed action plate 1
1 rotates slightly clockwise against the elastic force,
When the support stand 9 is in the action position, the action plate 11 is in the transfer position, so the picker roller 13 comes into contact with the card surface, and therefore the card P at the lower end is pulled out due to the frictional resistance with the outer periphery of the rotating picker rollers 13 and 14. The paper is then moved to the left in FIG. 1, and further held between the presser roller 6 and the feed roller 7, and sent to the reading section by the rotation of the feed roller 7.
When the withdrawal of one card is completed, the electromagnet 20
immediately deenergizes and returns the support base 9 to its inactive position.

When the support base 9 reciprocates between the inactive position and the active position, the belt B is stretched around the driven pulley 5, the interlocking pulley 17, and the auxiliary pulley 19, so the length between the respective pulleys of the belt B changes. However, since the total circumference does not change, the tension of belt B also does not change, and it does not come off each pulley.

Furthermore, since the belt B is stretched around the operating pulley 5 supported on the operating shaft 3, even if the pulley diameter of the driving pulley 2 is changed, the operating pulley 5 and the pulley 16 are always synchronized.

In this embodiment, the auxiliary pulley 19 is supported on a support base, but a support base other than the support base 9 may be fixed to the support shaft 8 to support the auxiliary pulley 19. good.

As described above, according to this invention, the operating shafts 3 and 5 are supported on the machine frame so as to be rotatable about a fixed axis in conjunction with the drive source, and the operating shafts are rotatable about an axis parallel to the operating shaft. A support stand 9 supported on the machine frame, working shafts 10 and 17 rotatably supported on the support stand about an axis parallel to the working shaft, and Roller 1 that can touch and separate the outer periphery from one side of the stacked cards
3 and 14, a first action of connecting the support to the support and rotating the support in one direction so as to connect the roller to the card surface, and a second action of rotating the support in the other direction so as to separate the roller from the card. an actuating means 20 that enables this, auxiliary shafts 18 and 19 supported on a support base so as to be rotatable about an axis parallel to the actuating shaft, and an endless shaft extending between the actuating shaft, the action axis, and the auxiliary shaft. The belt B has a shape of a belt B, and the operating shaft and the auxiliary shaft are arranged in relation to each other on the support base so that the tension of the belt does not loosen regardless of the rotational position of the support base due to the action of the actuating means. When the support base reciprocates to bring the roller into contact with and away from the card, even if the distance between the operating axis, working axis, and auxiliary axis changes, the circumference of the belt that is passed around each axis does not change. Since the belt does not sag or get too tense, the belt always maintains a constant tension and does not come off the pulley or break.This allows cards to be taken out reliably at all times and also extends the life of the device. .
