For this reason, when the drawer 2 is stored in the safe or placed on the floor, the contact portion is less likely to come into contact with the placement portion or the floor of the safe. Thereby, the malfunction that the grease apply | coated to the contact part adheres to the mounting part and floor of a safe can also be prevented.

Next, the state of the guide rail 4 and the rail receiver 3 when the drawer 2 is in the storage position will be described with reference to FIG. FIG. 4A is a perspective view showing the base portion and the drawer when the drawer is in the storage position, and FIG. 4B is the drawer-side base portion 92a and the drawer-side base portion 92a stored therein. It is CC sectional drawing of the figure (a) which shows the cross section of the drawer 2. FIG. In FIG. 5B, the components other than the rail receiver 3 and the guide rail 4 are omitted or simplified for easy understanding of the drawing.

As shown in FIG. 4 (b), the guide rail 4 has a substantially U-shaped cross section, and has a ceiling portion 41, a bottom portion 42, and a wall portion connecting the ceiling portion 41 and the bottom portion 42. 43. The wall portion 43 stands up in the vertical direction and faces the inner side in the width direction of the side surface portion 33 of the rail receiver 3. The ceiling portion 41 extends from the upper end portion of the wall portion 43 toward the outer side in the width direction, and faces the upper contact portion 31 of the rail receiver 3 from above. The bottom portion 42 constitutes a part of the bottom plate 921 of the drawer-side base portion 92a, and a portion of the bottom plate 921 that extends outward from the position where the lower end of the wall portion 43 is connected to the bottom portion 42 becomes the bottom portion 42. Equivalent to. The bottom portion 42 faces the lower contact portion 32 of the rail receiver 3 from below. Further, as shown in FIG. 2A, the ceiling portion 41 is not provided in the front portion of the guide rail 4. Further, a drop portion 921a that is lowered by one step is formed at the front portion of the bottom plate 921 in the drawer-side base portion 92a, and the bottom portion 42 of the guide rail 4 is not formed in this drop portion 921a. A reinforcing rib 411 is formed on the front side portion of the ceiling portion 41. The reinforcing rib 411 reinforces this portion because a large load is applied to the front portion of the ceiling portion 41 in a state where the drawer 2 is pulled out to the front side (see FIG. 5B). As shown in FIG. 4B, a guide groove 2231 is provided on the bottom wall 223 of the drawer 2. The guide groove 2231 extends in the depth direction, and the drawer 2 moves in the depth direction in a state where the restriction piece 5 (see FIG. 2) is inserted. Details of the guide groove 2231 will be described later.

FIG. 5 is a conceptual diagram for explaining a mode in which the drawer is attached to the drawer device and moved to the storage position. In FIG. 5, the drawer 2, the rail receiver 3, the drawer side base portion 92 a, the guide rail 4, and the guide roller 6 are shown in a simplified manner.

As shown in FIG. 5 (b), in the state immediately after the drawer 2 is inserted into the guide rail 4 (or in a state where the drawer 2 is opened largely by being pulled out to the front side), the guide roller has a guide roller as shown by an arrow. A counterclockwise moment about 6 is generated. As a result, the upper contact portion 31 of the rail receiver 3 is in strong contact with the ceiling portion 41 of the guide rail 4. It should be noted that the load applied to the ceiling portion 41 increases as the location where the upper contact portion 31 comes into contact with the front side of the ceiling portion 41. However, the reinforcing rib 411 is formed on the front side portion of the ceiling portion 41. Damage to the rail 4 is prevented. Hereinafter, the position of the drawer 2 shown in FIG. 5B may be referred to as an open position. When the drawer 2 is in the open position, the lower contact portion 32 of the rail receiver 3 is not in contact with the bottom portion 42 of the guide rail 4 or slightly depending on the weight of the drawer 2 and the weight of stored money. It will be in a state of touching.

Next, when the drawer 2 is pushed from the open position toward the storage position, the rail receiver 3 moves to the rear side while sliding with respect to the ceiling portion 41 of the guide rail 4, and accordingly, a counterclockwise moment. Gradually gets smaller. Eventually, the moment generated in the drawer 2 changes from a counterclockwise moment to a clockwise moment, and this clockwise moment gradually increases. When the drawer 2 is pushed to the storage position, as shown by an arrow in FIG. 5C, the clockwise moment with the guide roller 6 as a fulcrum is maximized, and the lower contact portion 32 of the rail receiver 3 is connected to the guide rail 4 It will be in the state which touched strongly the bottom part 42 of this. On the other hand, in order to take out the drawer 2 from the storage position shown in FIG. 5 (c), the drawer 2 is pulled out to the open position shown in FIG. 5 (b), and the guide is opposite to the mode shown in FIG. 5 (a). The rail receiver 3 may be pulled out from a portion of the rail 4 where the ceiling portion 41 and the bottom portion 42 are not formed.

As described above, grease is held in the grease recesses 311 and 321 and the grease grooves 312 and 322 of the upper contact portion 31 and the lower contact portion 32. For this reason, when the drawer 2 is put in and out, the sliding of the upper contact portion 31 with respect to the ceiling portion 41 becomes smooth, and the sliding of the lower contact portion 32 with respect to the bottom portion 42 becomes smooth.

The configuration of the restriction piece 5 that restricts the position of the drawer 2 in the width direction will be described with reference to FIG. FIG. 6A is a perspective view of the POS device 9 from which the drawer 2 has been removed as viewed obliquely from the upper right.

Thus, the left end of the restriction piece 5 is located on the left side by a length L3 from the protrusion 922, and the right end of the restriction piece 5 is located on the right side by a length L3 from the protrusion 922. Thereby, in the drawer 2 in the open position, the moving position, and the storage position shown in FIG. 7, the protrusion 922 is positioned at the center in the width direction of the guide groove 2231.

As shown in FIG. 8B, when the restriction piece 5 is attached to the protrusion 922 in such a direction that the reference portion 5c is located on the left side, the left end of the restriction piece 5 has a length L1 from the protrusion 922. Located on the left side, the right end of the restriction piece 5 is positioned on the right side by a length L2 from the protrusion 922. As a result, the position in the width direction of the restriction piece 5 moves to the left by the difference between the length L1 and the length L3 compared to the initial posture shown in FIG. As a result, the position in the width direction of the drawer 2 at the open position, during movement, and at the storage position shown in FIG. 7 moves to the left by the amount of movement of the restriction piece 5.

As shown in FIG. 8C, when the restricting piece 5 is attached to the protruding portion 922 in such a direction that the reference portion 5c is positioned on the right side, the left end of the restricting piece 5 has a length L2 from the protruding portion 922. Located on the left side, the right end of the restriction piece 5 is positioned on the right side by a length L1 from the protrusion 922. As a result, the position in the width direction of the restriction piece 5 moves to the right by the difference between the length L1 and the length L3, compared to the initial posture shown in FIG. As a result, the position in the width direction of the drawer 2 in the open position, the moving position, and the storage position shown in FIG. 7 moves to the right by the amount of movement of the restriction piece 5.

Even if the restriction piece 5 is attached to the protrusion 922 in such a direction that the reference portion 5c is located on the rear side, the position in the width direction of the restriction piece 5 is not different from the initial posture state shown in FIG. For this reason, in the present embodiment, the position in the width direction of the restriction piece 5 can be adjusted to the three states shown in FIG. 8A, FIG. 8B, and FIG. The position in the width direction of the drawer 2 in the open position, the moving position, and the storage position shown in FIG. 7 can also be adjusted in three stages. Thereby, the space | interval of the printer cover 91 and the front board 21 shown in FIG. 1 can be adjusted. In addition, the protrusion 922 and the fitting hole 5a to be fitted to this are formed in a polygonal shape of a pentagon or more, and the position in the width direction of the drawer 2 is changed by shifting the position where the fitting hole 5a is formed from the center of the restriction piece 5. You may employ | adopt the structure adjusted to four steps or more.

FIG. 9 is a diagram showing stepwise movements when the drawer 2 is housed in the storage position. In FIG. 9, in order to show the relationship between the guide groove 2231 and the front plate 21 that move while being regulated by the restriction piece 5, in the left side (a), the front portion of the guide groove 2231 and the restriction piece in FIG. 5 is shown in an enlarged view of an E portion surrounded by an ellipse, and in the right side (b), only the printer cover 91 and the front plate 21 are shown in a simplified manner.

As a result, as shown in FIG. 9 (b-1), the left end 21L of the front plate 21 is substantially aligned with the right end 91R of the printer cover 91 in the depth direction, or the left end of the front plate 21 The drawer 2 moves rearward with a slight gap between 21L and the right end 91R of the printer cover 91. Further, due to rattling or the like generated between the restricting piece 5 and the guide groove 2231, the left end portion 21L of the front plate 21 in the depth direction has a printer cover 91 as shown by a two-dot chain line in FIG. The drawer 2 may move to the rear side in a state where the drawer 2 overlaps the right end portion 91R.

Next, as shown in FIG. 9A-2, when the meandering portion 2231a is regulated by the regulating piece 5, the position of the guide groove 2231 moves to the right side. As a result, immediately before the drawer 2 is placed in the storage position, as shown in FIG. 9B-2, the position of the front plate 21 is also shifted to the right side, and the left end 21L of the front plate 21 and the right end of the printer cover 91 are A gap G occurs between the portion 91R. This interval G is set to be larger than the overlap in the case where the front plate 21 and the printer cover 91 overlap. When the drawer 2 is housed in the storage position, the straight portion 2231b is again restricted by the restriction piece 5 as shown in FIG. As a result, as shown in FIG. 9B-3, the position of the front plate 21 returns to the left side, and the restriction between the left end portion 21L of the front plate 21 and the right end portion 91R of the printer cover 91 is restricted in advance. It will be in the state which has the slight space | interval adjusted with the direction of the piece 5. FIG. Further, when pulling out the drawer 2 from the storage position, the state shown in FIG. 9 (b-3) having a slight space between the front plate 21 and the printer cover 91 is changed to FIG. 9 (b-2). The drawer 2 is once moved to a state having a gap G as shown. Thereafter, the drawer 2 is opened again by returning to the state where the front plate 21 is substantially aligned with the printer cover 91 as shown in FIG.

As in the present embodiment, immediately before the drawer 2 is housed in the storage position and immediately after the drawer 2 is pulled out of the storage position, a gap G is generated between the front plate 21 and the printer cover 91 to thereby pull out the drawer in the storage position. Even when the distance between the front plate 21 and the printer cover 91 is set to be small, inadvertent contact between the front plate 21 and the printer cover 91 can be avoided.

As described above, according to the cash drawer 10 of the present invention, when the drawer 2 is attached and detached, even if the drawer 2 is gripped, the upper contact portion 31 and the lower contact portion 32 are inadvertently touched and the hands are soiled. Less.

The present invention is not limited to the above-described embodiment, and various modifications can be made within the scope described in the claims. For example, in the above-described embodiment, a configuration having the upper contact portion 31 and the lower contact portion 32 that are sliding surfaces is employed as the contact portion, but a roller may be employed as the contact portion. For example, rollers may be provided on each of the upper end portion and the lower end portion of the rail receiver 3, and these rollers may contact the ceiling portion 41 and the bottom portion 42 of the guide rail 4. Moreover, in the said embodiment, although the structure which provides a pair of guide rail 4 corresponding to a pair of rail receiver 3 is employ | adopted, the ceiling part 41 and the bottom part 42 which one rail receiver 3 touches, and the other rail For example, one guide rail 4 having a substantially H-shaped cross-sectional view, in which the ceiling portion 41 and the bottom portion 42 are in contact with each other, can be employed.
