Description

[Detailed explanation of the invention] (a) Industrial application field This invention is applicable to the main body of an automatic teller machine used in financial services, for example, by controlling the built-in control mechanism and card processing of this teller machine. The present invention relates to a drawer structure for an accessory such as a mechanism, a passbook processing mechanism, a banknote feeding mechanism, etc., for inserting and removing the accessory.

(B) Prior Art A device that prevents the attachment from falling over by supporting the bottom surface of the tip of the attachment with an arm when the attachment is pulled out from the main body as described above is disclosed in, for example, Japanese Utility Model Application Publication No. 58-95746. Disclosed.

In the conventional structure described above, after the arm supports the appendage, a locking pin is artificially inserted in order to lock the arm in a supporting position so that the arm does not fold under the weight. However, such artificial manipulation is cumbersome and
It is easy to forget this, which can be dangerous, so a structure that automatically locks the arm as soon as it hangs would provide even more effective support.

However, on the other hand, there is a problem in that the arm does not automatically lock, and if the attachment is pulled out in an incompletely locked state, the arm will fold under the weight, causing the main body to fall over.

(c) Problems that the invention aims to solve This invention solves the problem of losing the weight balance with the main body by rotating the arm supporting the appendage to a vertical position when the appendage is drawn out and automatically locking it. The purpose of the present invention is to provide a structure for pulling out an appendage that can securely support an appendage that has been pulled out without fail, and prevent the attachment from being pulled out if the arm is incompletely locked, thereby preventing accidental overturning. do.

(d) Means for Solving the Problem This invention is a drawer structure for an accessory that can be taken in and out of the main body, and the base end of the arm, which has a caster attached to the free end, is connected so that the free end side is It can be rotated reciprocally between the lower surface position on the front side in the pull-out direction of the appendix and the vertical position on the rear lower side of the lower surface position, and is biased toward the vertical position and pivoted on the lower surface of the appendix nearer to the front side. A contact part is provided on the main body side for storing the hanging arm on the lower surface of the appendage based on the pushing of the appendage, and a cam that interlocks with the arm is attached to the pivot part of the arm, and the cam circumference is An engaging portion corresponding to the vertical position of the arm is formed on the surface thereof, and an intermediate position of a lock lever extending in the front-rear direction on the lower surface of the appendage and rearward from the arm pivot position is pivotally connected to the tip of the lock lever. A locking engaging part is formed on the rear end side of the locking lever, and a locking engaging part is formed on the rear end side of the locking lever. A guide pin protruding in the lateral direction is implanted, and the arm is placed on the movement path of the guide pin of the lock lever on the side of the main body corresponding to the guide pin of the lock lever at the pull-out position of the rotatable appendage to the vertical position. A lock release plate is installed that moves the locking engagement part of the lock lever in a direction in which it separates from the cam engagement part against the bias when the lock lever comes into contact with the guide pin, and the lock release plate is mounted in front of the lock release plate in the drawing direction. A drawer of an attached body is provided with a stopper that engages with the guide pin of the lock lever when the lock engaging part of the lock lever is disengaged from the cam engaging part, on the main body side at a position on the movement path of the guide pin at the cam position. It is characterized by a structure.

(e) Effect The pull-out structure of the appendage of this invention is such that when the appendage is pulled out and the arm reaches the pull-out position where it can rotate to the vertical position, the arm rotates to the vertical position by force, and the arm moves vertically. When the arm reaches the position to support the appendage, the locking engagement part of the lock lever engages with the engagement part of the cam that rotates in conjunction with the arm, and the arm is automatically locked in the vertical position. .

If the above-mentioned rotation of the arm to the vertical position is incomplete and the locking engaging part of the locking lever does not engage with the engaging part of the cam, the guide pin of the locking lever will come into contact with the stopper and no further rotation will occur. The attachments of the machine are prohibited from being pulled out, and accidental overturning is prevented.

When pulling (pushing) the pulled out attachment into the main body, the arm is returned to a position where it can be rotated vertically, so that the lock release plate comes into contact with the guide pin of the lock lever, and the locking engagement of the lock lever is released. When the mating part disengages from the engaging part of the cam and the appendage is further pulled in, the arm is pushed up by the abutting part on the main body side, such as the mouth edge, and folded to the lower surface position of the appendix. .

(f) Effects of the invention According to this invention, by pulling out the attachment from the main body, the arm equipped with casters automatically rotates to a vertical position, and the lock lever automatically locks this vertical position. Therefore, even if the entire attachment is pulled out from the main body, the attachment can be reliably supported in a stable state without having to be conscious of the locking operation, and even if the worker's weight is added to the attachment. This prevents the main body from falling over without disturbing its weight balance, and as a result, maintenance and inspection of the attachments becomes extremely easy.

Furthermore, if the locking engagement part of the lock lever is not fully engaged and the arm is not fully locked, the guide pin will come into contact with the stopper and the attachment will not be able to be pulled out. It is possible to reliably prevent the risk of the main body falling due to incomplete locking of the arm, thereby improving safety.

(g) Example of the invention An example of the invention will be described below in detail based on the drawings.

The drawings show the drawer structure of the attached body, and in FIGS. 1 to 4, the main body 10 is, for example, an automatic teller machine, and the appendix 11 is, for example, controls each processing mechanism built in this automatic teller machine. Corresponds to the control mechanism.

The above-mentioned attachment 11 is supported so as to be removable and removable by an appropriate rail mechanism provided on the back side and the main body 10, and the attachment 11 is connected to an engaging portion 13 formed at the rear end of the bottom plate 12. A stopper 14 provided on the main body 10 side prevents the appendage 11 from being pulled out at the maximum position.

Arms 1 for supporting the appendix 11 when it is pulled out are located on the left and right positions of the lower surface of the appendix 11 in the pullout direction (position closer to the front).
5 is installed.

Since the above-mentioned left and right arms 15 have the same structure, only one of them will be explained.

That is, the arm 15 has a caster 16 attached to its free end, and a cam 1 having a circumferential surface at its base end.
7 is fixed, and this cam 17 is pivotally connected by a shaft 19 to a support member 18 fixed to the lower surface of the appendage 11,
The arm 15 rotates between a lower surface position on the front side in the drawing direction of the attachment 11 and a vertical position rearward and downward from the lower surface position, and in the vertical position, a support is provided to prevent further rearward rotation. It is regulated by a stopper 20 implanted in the member 18, and is biased vertically by a spring 21.

Engagement portions 22 and 23 are cut out and formed on the circumferential surface of the cam 17, corresponding to the lower surface position and the vertical position of the appendage 11 of the arm 15.

On the upper surface side of the above-mentioned cam 17, there is a lock lever 2.
An engaging portion 25 formed in a protruding shape is located on the front end side of the lock lever 2 and is in contact with the circumferential surface of the engaging portion 25.
When the engaging portions 25 of 4 engage with the respective engaging portions 22 and 23 of the cam 17, the arm 15 is restricted to the lower surface position and the vertical position, and is locked at the respective positions.

The above-mentioned lock lever 24 extends in the front-back direction on the lower surface of the appendage 11 and on the rear side of the pivot point (shaft 19) of the arm 15, and the intermediate portion is formed by a support member 26 and a shaft 27 attached to the lower surface of the appendage 11. A guide pin 28 is installed on the rear side surface of the appendix 11 so as to be able to swing vertically. and a spring 30 stretched between the support member 29 and the rear end of the lock lever 24, the engaging portion 25 on the distal side
is always urged to be in contact with the circumferential surface of the cam 17.

The main body 10 is provided with a lock release plate 31 that acts on the guide pin 28 of the lock lever 24 described above, the front and rear ends of the lock release plate 31 are inclined upward, and the position of the lock release plate 31 is determined by the position where the arm 15 is attached. When the attachment 11 is in the drawer position where it can be rotated from the bottom position of the body 11 to the vertical position, in other words, the attachment 11 is in the rotation position where it can be rotated from the vertical position to the bottom position of the attachment 11. When this occurs, the guide pin 28 of the lock lever 24 is placed in a position to be pressed down, and this pressing force causes the engaging portion 25 to rotate upward, thereby preventing the engaging portion 22 and 23 of the cam 17 from engaging with each other. It becomes possible to remove it.

Further, a stopper 32 is fixed at a position on the movement path of the guide pin 28 on the front side of the lock release plate 31 of the main body 10 described above.
When the aforementioned engaging portion 25 of the lock lever 24 is incompletely engaged with the engaging portions 22 and 23 of the cam 17 and is in contact with the circumferential surface of the cam 17, the guide pin 28 of the lock lever 24 in contact with the appendage 11
Only when the above-mentioned engagement is complete, the guide pin 28 is allowed to pass and the attachment 11 is allowed to be pulled out.

Note that the lower edge (contact portion) 33 of the main body 10 faces the rear side of the arm 15 in the vertical position, and when the appendage 11 is pushed in, the arm 15 comes into contact with the lower edge 33. The arm 15 can then be folded onto the underside of the appendage 11.

In the drawer structure of the appendix 11 constructed as described above, when the appendix 11 is stored in the main body 10, the arm 15 is folded to the lower surface position of the appendix 11 (see Fig. 1). The engaging portion 25 of the lock lever 24 engages with the engaging portion 22 of the cam 17 to lock the arm 15 in the lower position.

When the attachment 11 is pulled out and reaches a position where the arm 15 can be rotated to the vertical position (see the white arrow in FIG. 2), the guide pin 28 of the lock lever 24 is pulled out.
is guided to the lower surface of the lock release plate 31 and pressed down, so the engaging portion 25 of the lock lever 24 moves upward and disengages from the engaging portion 22 of the cam 17, and the arm 15
is rotated to the vertical position by the biasing force of the spring 21 and its own weight, and the attachment 11 is further pulled out and the guide pin 28 of the lock lever 24 is disengaged from the lower surface of the lock release plate 31, so that the lock lever 24 is no longer engaged. The engaging portion 25 moves downward under the biasing force of the spring 30 and engages with the engaging portion 23 of the cam 17, thereby locking the arm 15 in the vertical position (see FIG. 2).

When the appendix 11 is pulled out in this state (see Figure 3), the casters 16 of the arm 15 touch the floor and support the appendix 11, so even if the entire appendix 11 is pulled out from the main body 10, the weight of the main body 10 The appendage 11 can be supported without losing balance.

Note that after the engaging portion 25 of the lock lever 24 moves upward, the arm 15 is not fully rotated to the vertical position.
If the engaging part 25 does not engage with the engaging part 23 of the cam 17, the above-mentioned engaging part 25 comes into contact with the circumferential surface of the cam 17, as shown by the imaginary line in FIG. Since the guide pin 28 at the rear of the lock lever 24 is not completely raised upwards (it is in the lower position), the guide pin 28 mentioned above is
collides with the stopper 32, and the attachment 11 cannot be pulled out any further, thereby preventing a dangerous situation in which the weight balance of the main body 10 is disturbed.

As mentioned above, when the appendage 11 cannot be pulled out, the vertical rotation of the arm 15 is stuck, so all you have to do is push in the appendage 11 and try again, but retrying is also inconvenient. If so, check arm 15 for failure.

When storing the above-mentioned appendix 11, the appendix 1
1 into the main body 10 side (see the black arrow in Figure 2).
When the attachment 11 reaches the storage position of the arm 15, the lock release plate 31 presses down the guide pin 28 of the lock lever 24 with its lower surface, so that the lock lever 2
The engaging portion 25 of the cam 17 moves upward and engages the engaging portion 2 of the cam 17.
3, and when the appendix 11 is further pushed in in this state, the arm 15 is pushed up by the lower lip (abutting portion) 33 of the main body 10 and is housed in the lower surface position of the appendix 11.

Further, when the guide pin 28 of the lock lever 24 comes off the lower surface of the lock release plate 31, the engaging portion 25 of the lock lever 24 moves downward and engages with the engaging portion 22 of the cam 17, and the arm 15 is locked in the lower surface position. (See Figure 1).

Regarding the correspondence between the structure of this invention and the structure of the above-mentioned embodiment, the guide part of the lock lever of this invention corresponds to the guide pin 28 of the embodiment, the abutting part corresponds to the lower lip 33, and other parts. Although this corresponds to the configuration of the same part names in the embodiment, the present invention is not limited to the above-mentioned embodiment.
