Abstract

PURPOSE:To reduce impact noise occurring at the time of stopping a money case at a half-opening position when the money case is simultaneously opened with the closing processing of a register. CONSTITUTION:A pair of abutting bodies 16 whose mutual contact parts interfere with the drawer case 1 or a projecting part 15 projectingly formed at the money case by the slide of the money case are provided in the drawer case 1 or money case so as to freely contact and separate. The abutting bodies 16 are abutted by an energizing part 22 and the projecting part 15 and the abutting bodies 16 are made to collide with each other at the time of the half- opening of the money case so that the money case is once stopped at the half- opening position. Recessed parts 21 for permitting the projecting part 15 to go in are formed at both ends of the contact parts of the abutting bodies 16. The projecting part is surely stopped by being abutted on the abutting body even if the abutting bodies and the projecting part are worn. Therefore, a flexible member which makes impact noise small may be used for the abutting bodies and the projecting part.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cash register drawer device for storing money.

0002

2. Description of the Related Art Conventionally, there is a cash register drawer device in which a money case for storing money is provided in a drawer housing so as to be freely drawn out, and the money case is opened at the same time as the cash register is closed. This type of device is generally provided with a stop mechanism that temporarily stops the money case being opened in a half-open state. This stop mechanism prevents theft by storing coins in the front of the money case and bills in the back, so that when the money case is first opened, the money case will not be opened until the banknotes are exposed. plays an important role in

Conventionally, as a stop mechanism for such a money case, a protrusion is provided to protrude from the bottom surface or side surface of the money case, and a dogleg-shaped leaf spring that comes into contact with this protrusion is attached to the drawer housing. There are structures that are attached to the That is, the leaf spring is attached to the drawer housing in a cantilevered manner so that its mountain-shaped portion is located on the locus of movement of the protrusion and is bent in the same direction as the movement direction of the protrusion. Further, the attachment position of the leaf spring is a position where the protrusion of the money case in the half-open position interferes. In such a structure, when the money case is opened at the same time as the register is closed, the protrusion comes into contact with the leaf spring, and the money case is kept in a half-open state. In this state, coins can be taken in and out of the money case. When it is necessary to take in and take out banknotes, the cashier further manually pulls out the money case from this state, allowing the banknotes stored in the back side of the money case to be taken out.

0004

[Problem to be Solved by the Invention] When the money case is opened, the abutting body on the money case side and the leaf spring on the drawer housing collide with each other, so both the abutting body and the leaf spring are made of metal, etc. that are difficult to wear. It is necessary to form the The abutting body and the leaf spring are positioned under a delicate force relationship, so if either one of them is severely worn, the balance of the force between the two will be disrupted, causing the abutting body to push the leaf spring when the money case is opened. This is because situations arise that require you to overcome them. For this reason, both the abutting body and the leaf spring have to be manufactured from metal materials or the like, but in this case, there is a drawback that a large collision sound is generated at the time of collision.

[0005]

[Means for Solving the Problems] The present invention provides a drawer housing with a money case that can be freely pulled out between a locking position and a fully open position, and a locking portion that locks the money case at the locking position. , a release part for releasing the locking of the money case by the locking part, and an opening part for biasing the money case in the opening direction, and the drawer housing or the money case is provided with a release part that releases the locking of the money case by the locking part, and the drawer housing or the money case is provided with a release part that releases the locking of the money case by the locking part. A protrusion is formed protruding in the direction, and the protrusion and the mutual contact portion interfere with each other in the half-open position of the money case in the drawer case or money case where the protrusion is not formed, and a recess is formed at the interference position with the protrusion. A pair of formed abutting bodies that can be freely moved toward and away from each other are provided, and a biasing portion is provided that urges these abutting bodies in a direction in which the abutting bodies come into contact with each other.

[0006]

[Operation] Therefore, when the locking of the money case by the locking portion is released by the release portion, the money case is released by the opening portion. At this time, the protrusion and the contact body interfere with each other, and the money case stops at the half-open position. If you want to further open the money case from this half-opened state, pull the money case by hand. Then, the protrusion enters the recess and causes the abutting bodies to separate from each other against the force of the biasing part, so that the interference between the protrusion and the abutting body is released and the money case is further opened. On the other hand, since the abutting bodies are urged by the biasing part in the direction that the abutting bodies come into contact with each other, even if the abutting bodies and protrusions are worn out due to repeated use, the protrusions and the abutting bodies are The money case that flies out in the opening direction due to interference is reliably stopped at the half-open position. Therefore, even if the protrusion and the contact body are made of a flexible member such as resin to reduce the collision noise, sufficient durability can be obtained. In addition, to return the money case to its original position, push the money case back. Then, since the protrusion separates the abutting bodies, interference between the protruding part and the abutting bodies is released, and it becomes possible to push the money case back to the locking position. The money case pushed back to the locking position is locked by the locking portion.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS. 1 to 3. A drawer housing 1 in the form of a flat housing is provided, and a money case 2 is housed in the drawer housing 1 so as to be slidable from a locking position A to a fully open position B shown in FIG. That is, rails 3 are formed on both side walls inside the drawer housing 1, and a pair of rollers 4 that roll and move on these rails 3 are rotatably attached to both rear sides of the money case 2. There is. Further, rails (not shown) are formed on both sides of the money case 2, and a pair of rollers (not shown) that hold the rails are rotatably attached to the drawer housing 1, where the money case 2 is attached to the drawer. It is supported by the housing 1 so that it can be freely drawn out. The money case 2 is provided with a coin case 5 on the front side and a bill case 6 on the back side.

The invention also includes a locking portion 7 that locks the money case 2 at the locking position A with respect to the drawer housing 1, and a release portion that releases the locking of the money case 2 by the locking portion 7. 8 is provided. That is, a locking pawl 9 is attached to the back surface of the money case 2, and a locking body 10 for hooking the locking pawl 9 is rotatably attached to the drawer housing 1 about a fulcrum 11. This locking body 10 is provided with a biasing portion (not shown) that applies a biasing force in the direction of engagement with the locking pawl 9, and the locking portion 7 is formed here. Further, a movable core 13 of a solenoid 12 is connected to the free rotation end of the locking body 10, and the release portion 8 is configured here. Furthermore, the money case 2 located at the locking position A is attached to the drawer housing 1.
An opening spring 14 is attached as an opening section that is kept in a compressed state between the back surface and the rear surface of the housing.

Next, on the bottom surface of the money case 2,
A protrusion 15 is screwed to the center. This protrusion 15
is formed by bending a flat plate member into a dogleg shape that is slightly bent toward the side of the money case 2, and protrudes downward from the lower surface of the money case 2.

[0010] Furthermore, a pair of contact rollers 16 as contact members are attached to the bottom surface of the drawer housing 1. That is, a flat mounting plate 17 is screwed to the bottom surface of the drawer housing 1, and one of the contact rollers 16a is rotatably mounted on this mounting plate 17. A rotary plate 19 is rotatably attached to a position adjacent to the contact roller 16a and moves toward and away from the contact roller 16a by rotating around a screw-fastened fulcrum 18. The moving plate 19 has the contact roller 16a.
The other contact roller 16b is rotatably attached at a position where the circumferential surfaces 20 come into contact with and separate from each other. Here, these contact rollers 16 are positioned such that their axes both face a direction perpendicular to the moving direction of the money case 2. The contact rollers 6 are arranged so that their tangent lines to each other are located on the locus of movement of the protrusion 15, and when the money case 2 is in the half-open position C shown in FIG.
5 is placed at a position where it interferes. For this reason, recesses 21 into which the protrusions 15 enter are formed at both ends of the contact portion between the pair of contact rollers 16. Note that the contact roller 16 is made of a flexible material that does not generate a large collision sound, such as a resin such as Delrin.

Further, between the rotatable free end of the rotary plate 19 and the mounting plate 17, a biasing spring 22 is provided as a biasing portion for biasing the two abutting rollers 16 in the abutting direction. is installed.

In such a configuration, the solenoid 12 is activated simultaneously with the closing process of the electronic cash register (not shown).
is energized and the movable iron core 13 is drawn in, thereby causing the locking body 10 to rotate around the fulcrum 11. As a result, the engagement of the locking body 10 with the locking pawl 9 is released, and the money case 2 is urged by the urging spring 14 and opened.

At this time, the protrusion 15 moves as the money case 2 slides and collides with the contact roller 16, so that the money case 2 is stopped at the half-open position C and kept in the half-open state. In this state, only the coin case 5 is opened, so the cashier takes out coins from the coin case 5 and exchanges money with the customer. On the other hand, if it is necessary to exchange banknotes in order to receive or receive money, the cashier further pulls out the money case 2 by hand. Then, the protrusion 15
moves between the two contact rollers 16, and the money case 2 is opened to the fully open position B, making it possible to take out the banknotes from the banknote case 6. At this time, one of the contact rollers 16b rotates about the fulcrum 18 and separates from the other contact roller 16b against the urging force of the urging spring 22, and the two contact rollers 16 It rotates due to frictional resistance with the section 15. Note that in order to close the money case 2 located at the fully open position B, the money case 2 is pushed toward the locking position A. Then, the protrusion 15 passes between the two contact rollers 16 and the locking pawl 9 is locked to the locking body 10, so that the money case 2 is fixedly stored in the locking position A. .

[0014] Since the contact roller 16 is formed of a flexible member, it wears out due to repeated collisions with the protrusion 15 when the money case 2 is opened. However, due to the biasing spring 22, the two contact rollers 1
6 is in contact with each other, even if the contact roller 16 is worn out, the stopping operation of the protrusion 15 by the contact roller 16 will not be hindered. Therefore, the flexible abutment roller 16
This makes it possible to absorb the collision sound when the protrusion 15 collides with the protrusion 15, and also in this case, sufficient durability is ensured. Moreover, in this embodiment, the contact roller 16 rotates as the protrusion 15 collides with or passes by. Therefore, the wear of the contact roller 16 itself can be minimized.

Further, the contact roller 16 rotates as the protrusion 15 passes therethrough. Therefore, when the money case 2 is slid and the protrusion 15 is passed between the two contact rollers 16, the money case 2 slides smoothly and the operational feeling is improved. However, the contact roller 16 will not rotate unless there is sufficient frictional resistance between the contact roller 16 and the protrusion 15, but even in this case, since the contact surface of the contact roller 16 is curved, these contacts will not rotate. The protrusion 15 smoothly slides between the contact rollers 16, and the sliding movement of the money case 2 is maintained smoothly.

In addition, in the implementation, the contact roller 16
The abutting bodies configured as such may be formed of non-rotatable members, the mutual contact portions may be line contact or surface contact, and the protrusion 15 may be formed of a flexible member. Furthermore, a structure may be adopted in which the protrusion 15 is attached to the drawer housing 1 side, and the contact roller 16 and the like are attached to the money case 2 side.

Next, a second embodiment of the present invention will be explained based on FIGS. 4 and 5. The same parts as in the first embodiment are indicated by the same reference numerals, and explanations thereof will be omitted. In this embodiment, the protrusion 15
The structures of the contact roller 16 as the contact body and the biasing spring 22 as the biasing portion are different from those of the first embodiment. That is, there is an L-shaped roller plate 3 on the back of the money case 2.
1 is attached to the roller plate 31, and a protrusion 32 formed by a freely rotatable roller with its axis oriented vertically is attached to the roller plate 31. This protrusion 32 is arranged below a horizontal plane that includes the lower surface of the money case 2 housed in the drawer housing 1.

Furthermore, a pair of abutting pieces 33 as abutting bodies made of resin or the like are disposed at positions interfering with the protrusion 32 in the half-open position C of the money case 2. . These contact pieces 33 have a triangular shape with two sides other than the base having different lengths, and are rotated around a support shaft 34 erected on the bottom surface of the drawer housing 1 with the two sides facing each other. It is attached so that it can move freely. Here, the contact piece 3
3 is located near the intersection of the bottom and long sides of these contact pieces 33. Further, mounting holes 35 are formed in the abutting pieces 33 so as to be located closer to the intersection of the bottom side and the long side than the rotational fulcrum of the contact pieces 33, and these mounting holes 35 are provided with mounting holes 35 that are located closer to the intersection of the bottom side and the long side than the rotational fulcrum of the contact pieces 33. Pin 36 installed on the bottom of 1
The other end of a biasing spring 37 serving as a biasing portion is hooked on one end of which is fixed to. Therefore, each part is configured so that the contact pieces 33, one end of which is pulled by the biasing springs 37, rotate about the support shaft 34 in a direction in which they contact each other. A clamping portion 38 is formed in the portions of the contact pieces 33 that contact each other, into which the protrusion 32 is fitted with the contact pieces 33 slightly separated. Recesses 22 are formed at the front and rear.

In such a configuration, when the money case 2 is biased by the biasing spring 14 and slides from the locking position A in the releasing direction, the protrusion 32 moves accordingly, and the pair of contact pieces 33 collide with Then, the contact pieces 33 rotate in the direction away from each other against the force of the biasing spring 37, and the protrusion 32 enters the clamping part 38 of the contacting piece 33 and is clamped by the clamping part 38. As a result, the money case 2 is kept in the half-open state at the half-open position C. At this time, since the abutment piece 33 rotates due to the collision of the protrusion 32, the collision between the protrusion 32 and the abutment piece 33 is buffered. Therefore, when the protrusion 32 and the abutting piece 33 collide, the collision noise is reduced. Further, even if the contact piece 33 is formed of a flexible member such as resin in order to further reduce the collision noise, severe wear of the contact piece 33 can be prevented.

Moreover, since the two abutting bodies 33 are in contact with each other by the biasing spring 37, even if the abutting piece 33 is worn out, the stopping operation of the protrusion 32 by the abutting piece 33 is not hindered. Therefore, the collision between the protrusion 32 and the abutment piece 33 is buffered, thereby preventing severe wear of the abutment piece 33, and together with this, a device with excellent durability can be obtained.

Furthermore, when the money case 2 is in the half-open state, the protrusion 32 is clamped by the clamping part 38, so the money case 2 is fixed at the half-open position C, and unless a certain amount of force is applied, it will return to the fully open position. It does not slide in the direction of B or in the direction of locking position A. Therefore, when taking out coins from the coin case 5, even if force is applied to the money case 2 in the sliding direction, the money case 2 remains in the half-open position C.
It becomes easy to store small change.

Effects of the Invention The present invention provides a drawer housing or a money case with a protrusion formed in a direction perpendicular to the slide direction of the money case, and a drawer housing or money case in which the protrusion is not formed with the protrusion. A pair of abutting bodies that can be moved toward and away from each other are provided, in which the protrusions and the contact portions of each other interfere with each other in the half-open position, and a recess is formed at the interference position with the protrusions. Since a biasing part is provided that biases the bodies in the direction of contact, even if the contact parts between the protrusion and the contact body wear out, the protrusion and the contact body will interfere and the money case will not be opened halfway. Since it can be stopped at a certain position, a member such as resin can be used for the abutting body, which has the effect of reducing the impact noise caused by the collision between the protrusion and the abutting body.
