Description of the Related Art Recently, transaction counter devices such as bookkeeping machines for making entries in passbooks, online teller machines for managing cash, and multifunctional devices thereof have become popular at transaction counters in financial institutions and the like. The most typical transaction counter device has a bookkeeping mechanism that prints information on a passbook and a cash management function that allows quick information on daily transaction amounts.

FIG. 9 shows a side view of an example of a transaction counter device to which the present invention is applied. In the figure, the main body of the transaction counter device 1 includes a table 5 equipped with a printer 2, a display 3, and a keyboard 4. It has a movable table structure that is slidably held.

On the other hand, the counter 7 is composed of a horizontal part 8, a vertical part 9, and legs 10 provided on both sides.
Those of a predetermined length (for example, about 1.5 m) are installed in series.

A plurality of transaction counter devices 1 are usually installed at intervals in a predetermined layout, with the back side of the transaction counter device 1 pressed against the vertical portion 9 of the counter 7. Therefore, the printer 2 and the display 3 are located below the horizontal part 8 of the counter 7, the keyboard 4 is located to the left of the horizontal part 8 in the figure, and the keyboard 4 is located to the left of the table 5 (not shown). An attendant sitting on a chair can operate the transaction counter device 1 while interacting with a customer on the right side of the counter 7 in the figure.

With such a configuration, when performing periodic maintenance or troubleshooting of this transaction counter device 1, a worker must work from a position in front of the device 1, that is, to the left or diagonally in front of the device 1 in FIG. In this sense, the transaction counter device 1 is a type of front maintenance device. When maintenance work on the device 1 requires work from above, the horizontal part 8 of the counter 7 is above the printer 2 and display 3 of the table 5 and will get in the way of the work, so move the table 5 forward. That is, by pulling the printer 2 and display 3 out to the left of the counter 7 in the figure, the printer 2 can be removed.
It is now possible to work on the display 3 and display 3 from above.

By pushing down or pulling up the table 5 in a predetermined positional relationship with respect to the desk 6, the hook portion 12 of each tongue piece metal fitting 11 attached to the table 5 is attached to the desk 6.
Since the table 5 can be inserted and removed freely through the insertion/extraction notch 18 into the groove 17 of the groove fitting 16 attached to the table 5, the table 5 can be attached to and removed from the desk 6 with a single touch. In addition, when the table 5 is attached to the desk 6, the table 5 is moved forward and backward,
When pushed in the left and right directions in the figure, the roller 15 moves to the groove metal fitting 16.
Since the table 5 rolls while being supported by the upper surface of the table 5, the table 5 moves smoothly in the direction of arrow A. The stroke of movement of the table 5 is determined by the difference between the length C of the groove 17 and the width dimension B of the hook portion 12. In FIG. 9, the solid line table 5 shows the position D pushed into the desk at one end of the stroke, and the chain line table 5 shows the position E pulled out from the desk at the other end of the stroke.

In the transaction counter device as described above, the table 5 is normally used in the position D pushed into the desk, so a mechanism for locking the table 5 in the pushed position D is required.

[Conventional technology]

Conventionally, the table was fixed in place using a magnetic rubber or ball catch.

[Problem that the invention attempts to solve]

However, with this method, the fixation of the table was unstable, and there was a risk that the lock would come off.

[Means to try to solve problems]

The present invention provides a table locking mechanism that eliminates the above problems and operates smoothly and reliably.
The means is a table locking mechanism in a movable table structure that is movable between a position where the table is pulled out from the desk and a position where the table is pushed into the desk. a lever provided in a guide groove of the table, and the guide includes a slope portion that rides on the lever when the table moves toward the pushed-in position, and a lever that engages the lever when the slope portion rides over the lever. and a locking part that locks the lever, and the engaging part of the lever is movable near and far with respect to the movement path of the guide, and is biased in a direction approaching the movement path of the guide. This is achieved by a table lock mechanism.

[Effect]

The above-mentioned table lock mechanism works because when the table is moved from the position where it is pulled out from the desk to the position where it is pushed into the desk, when the guide of the table comes to the position opposite to the lever, the sloped part of the guide rides on the lever. After the lever is pushed away from the moving path of the guide, the locking part of the guide of the table that has moved further locks with the engaging part of the lever, and in this state, the lever is urged in the direction of approaching the guide. Because of this, the above-mentioned lock will not come off naturally. Further, the table can be easily unlocked by moving the lever against the biasing force away from the movement path of the guide and toward the position where the table is pulled out from the desk.
