Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a select bar setting mechanism for moving and setting the select bar of a card retrieval device from a retracted position to a retrieval position.

(Background Art) Card search devices that search for a card having a specified code from among a large number of cards are widely used. For example, the card search device moves and sets a select bar of a specified code to a search position from among a group of select bars arranged parallel to each other on a plane, and then places one bar on top of the selected select bar. It is configured to select and search for a card having a code corresponding to a designated code by placing a large number of cards with codes on the sides and shifting them laterally.

Such a card search device uses a select bar set mechanism for selectively raising a select bar of a designated code to a search position.

However, all conventional select bar setting mechanisms have problems in that they are complicated, have a slow setting speed, and generate noise during bar setting.

(Object of the invention) An object of the invention is to provide a select bar set mechanism for a card retrieval device which has a simple mechanism, has a fast setting speed, and does not generate noise during bar setting.

(Structure of the invention) In order to achieve the above object, the selection bar set mechanism of the card search device according to the invention moves a group of selection bars arranged in parallel on a plane from a retracted position to a search position in accordance with a selected code. In a select bar set mechanism of a card retrieval device, a preset lever group provided corresponding to the select bar group, and a preset lever group corresponding to a code selected from the preset lever group are provided. a set holding means for setting and holding the lever in a position where it engages with the select bar; and a set holding means for engaging the set and held preset lever with the select lever and moving it in the direction of the search position. and a reset holding means that moves the select bar to the search position and resets and holds the preset lever in a position where it does not engage with the select bar. .

According to the above structure, the object of the present invention can be completely achieved.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings and the like.

FIG. 1 is a side view showing an embodiment of the select bar set mechanism of the card search device according to the present invention;
The figure is a plan view showing the arrangement of the preset lever of the mechanism of the embodiment, and FIGS. 3 and 4 are diagrams for explaining the operation of the mechanism of the embodiment.

The selection bar 11 is selectively raised in accordance with a designated code, and is used to search for cards by horizontally shifting cards having the corresponding code. The selection bar 11 is provided with a groove 11b, and guided by a shaft 11a, moves upward to the left in FIG. 1 to a search position. As shown in FIG. 2, the selection bars 11 are provided in parallel on a plane in a number corresponding to the number of codes.

The preset lever 7 is used to set the select bar 11, and is set in advance to a position where it engages with the select bar 11 according to a designated code. The preset lever 7 is pivotally supported by a shaft 7c, and has a key portion 7a that engages with the select bar 11 at its tip and a protrusion 7b for resetting at its top. Preset lever 7 is
As shown in FIG. 2, a number corresponding to the selection bars 11 are provided.

The set holding means are solenoid 6 and magnet 9.
It is composed of etc. The preset lever 7 is set by the solenoid 6 to a position where it engages with the select bar 11. The same number of solenoids 6 are provided on the printed circuit board 16 in correspondence with the preset levers 7, as shown in FIG. Due to installation space, they are arranged in two rows. The solenoid 6 is energized by turning on a selection button corresponding to a code (not shown), and attracts the preset lever 7. The preset lever 7 rotates counterclockwise in FIG. 1 about a shaft 7c that is attracted by the solenoid 6, and is held by a magnet 9 located above the rear. The magnet 9 is a magnet for holding the preset lever 7 in the set state.

The preset lever driving means is constructed as follows. A cam 2 is provided on the output shaft of the motor 1. A cam follower 3 is in contact with the cam 2. The cam follower 3 is driven by the cam 2, and a limiter lever 19 on which the cam follower 3 is pivotally supported.
oscillate. The limiter lever 19 is fixed to a shaft 19a, and the shaft 19a is pivotally supported by a side plate (not shown). The limiter lever 19 is biased counterclockwise in FIG. 1 by a spring 15 so that the cam follower 3 comes into contact with the cam 2. The set lever 18 is fixed to a shaft 19a, and a mounting table 20 as shown in FIG. 2 is provided. Mounting table 2
0 slides by a sliding roller 4 guided by a sliding groove 5 provided in the side plate.

Next, the operation of the preset lever driving means will be explained. When the cam 2 is rotated by the motor 1, the cam follower 3 is driven, and the mounting table 20 is moved to the left in FIG. 3 via the limiter lever 19, the shaft 19a, and the set lever 18. At this time, the preset lever 7, which has been set to a predetermined code on the mounting table 20, moves to the left and raises the selection bar 11 using the key portion 7a.

The reset holding means is composed of a reset bar 8, a magnet 10, etc. Select bar 11
When the preset lever 7 is raised to the search position, the protrusion 7b provided at the top of the preset lever 7 engages with the reset bar 8. At the same time, the preset lever 7 separates from the magnet 9, rotates counterclockwise in FIG. 4, and is attracted and held by the magnet 10. The magnet 10 is a reset holding magnet for holding the preset lever 7 in a reset state.

After the selection bar 11 is moved to the search position, the set lever 18 is returned to the initial position together with the mounting table 20 by the return spring 17. A light shielding disc 12 is provided at the tip of the output shaft of the motor 1, and when the photo sensor 14 detects that the motor 1 has returned to its initial position, the motor 1 is stopped. Note that the selection bar 11 is retracted to its original position by an appropriate method.

(Effects of the invention) As explained in detail above, according to the invention,
With a simple mechanism, the selection bar can be quickly set at the search position without generating noise when setting the bar.
