In this state, the fixing pin 551 of the fixing member 550 is positioned in the locking groove 5342, and the side wall of the locking groove 5342 is disposed to surround the fixing pin 551.

That is, the locking groove 5342 serves as a stopper against the fixing pin 551 to prevent the fixing member 550 from being detached from the outside.

At this time, the latching pin 5347 of the latching part 534 is positioned on the right side of the movement guide groove 5344 and is prevented from being caught in the latching guide groove (FIG. 7, 122). Whereby the coupling between the auxiliary storage chamber 100 and the main body 1 is released.

The first extension portion 5352 of the rotation limiting portion 535 is pushed by the support pin 552 of the fixing member 550 to move backward from the insertion guide groove 5211, The restricting portion 535 is rotated and positioned as a whole.

15, the positions of the latch portions 524 and 534 of the first and second latch devices are the same as the positions of the latch portions 524 and 534 of FIGS. 14A and 14B, Maintains a state in which the storage compartment 20 of the main body is closed.

At this time, the engaging pins 5247 and 5347 of the engaging portions 524 and 534 are positioned on the right side of the engaging guiding grooves 112 and 122 to prevent them from being caught in the engaging guiding grooves 112 and 122.

The stoppers 111 and 121 are located in the stopper grooves 523 and 533 and the stopper grooves 523 and 533 surround the rear and the sides of the stoppers 111 and 121.

In this state, when the door 30 and the auxiliary storage compartment 100 are engaged and the user pulls the door 30, the door 30 and the auxiliary storage compartment 100 rotate forward at the same time, 20 are opened.

Particularly, the latching pins 5247 and 5347 are located on the right side of the latching guide grooves 112 and 122. Since the latching guide grooves 112 and 122 are opened forward, Even if it moves forward along the guide groove 100, it can move freely without being caught by the engagement guide grooves 112 and 122. [

Therefore, the door 30 and the auxiliary storage room 100 can be opened smoothly.

As shown in FIG. 16 (a), the latching parts 524 and 534 of the first and second latch devices serve to hold the fixing member 550.

The engaging grooves 5242 and 5342 of the engaging portions 524 and 534 surround the fixing pins 552 of the fixing member 550 to prevent the fixing member 550 from being detached.

Thus, the door 30 and the auxiliary storage compartment 100 can be engaged with each other.

The motion guide portion 526 moves only by the pressing operation of the pressing portion 522. Since the pressing portion 522 is provided only in the first latch device, Needs to be prepared.

The insertion portion 5262 of the movement guide portion 526 is inserted into the first insertion groove 5244 to prevent the rotation of the latching portion 524. The contact piece 5263 provided in the motion guide part 526 may remain in contact with the pressing part 522 and may rotate at any time when the pressing part 522 advances. Thereby causing the rotation of the latching portion 524.

The fixing member 550 is inserted into the first and second guide supports 510 and 540 as shown in FIG. 16 (b).

The insertion guide grooves 513 and 543 provided in the first and second guide supporting portions 510 and 540 guide the movement of the fixing pin 552 of the fixing member 550 in a slanting shape.

When the fixing pin 552 is positioned at the rear end of the insertion guide grooves 513 and 543, the front of the fixing pin 552 is caught by the engaging protrusions 516 and 546 extending from the housing 551 and 541 Thereby preventing the fixing pin 552 from falling in the frontal direction other than the oblique direction.

17 (a) shows an intermediate process in which the fixing member 550 is separated from the first latch device 520, and FIG. 17 (b) (550) are completely separated from each other.

When the button 610 provided on the knob 32 shown in FIG. 10 is pressed, the internal link structure operates, and the protrusion 630 moves backward.

17 (a) and 17 (b), the pressing portion 522 is moved into the housing 521 by the protrusion 630, and the movement guide portion 526, respectively.

When the contact piece 5263 is pressed, the movement guide portion 526 rotates, and the rotation direction of the movement guide portion 526 is clockwise in the figure.

The insertion portion 5263 is separated from the first insertion groove 5244 of the latching portion 524.

Since the engaging portion 524 is connected to the movement guide portion 526 by the second elastic member 5292 when the movement guide portion 526 moves clockwise, And the engaging portion 524 is rotated in the counterclockwise direction.

Accordingly, the latching groove 5242 rotates forward from the side, and the latching state with the latching pin 552 is released so that the latching pin 552 can move forward.

On the other hand, when the engaging portion 524 rotates in the counterclockwise direction, the engaging pin 5247 moves to the left side of the moving guide groove 5244. It will move to the right side of the engaging guide groove (FIGS. 10 and 112) and be surrounded by the engaging step 112a of the extending groove of the engaging guide groove 112, which will be described later.

The first extension 5252 of the rotation restricting portion 525 is in contact with the fixing pin 552 of the fixing member 550. The rotation restricting portion 525 restricts the first elasticity Member 5291 as shown in Fig.

The first elastic member 5291 is connected to the second extension portion 5292 and provides an elastic restoring force for pulling the second extension portion 5292. Accordingly, It has a property of turning in the opposite direction.

Accordingly, when the fixing member 550 is released from the engagement with the engagement portion 524, the rotation limiting portion 525 rotates counterclockwise, and the first extension portion 5252 is engaged with the engagement pin 524, (552) in the forward direction.

In this state, when the user pulls the door (see FIG. 1) forward, the fixing member 550 comes out from the insertion guide groove 5211 in the forward direction.

When the fixing member 550 is completely released from the latch device 520, the rotation restricting portion 525 further rotates counterclockwise and the insertion portion (not shown) provided in the rotation restricting portion 525 5255 are inserted into the second insertion groove 5245 provided in the engaging portion 524.

Thereby, it is possible to prevent the latching portion 524 from further rotating.

As a result, the door 30 and the auxiliary storage 100 are separated from each other and the bobbin storage compartment 100 is located in the main body. When the user pulls the door 30 and opens it, So that the user can receive or withdraw the goods.

The second latch device 530 is different from the first latch device 520 in that the movement guide portion 526 is omitted and the engagement and disengagement between the latch portion and the fixing member is performed by the second latch device 530 The separating operation between the second latch device 530 and the fixing member 550 will be replaced with the description of the separating operation between the first latch device 520 and the fixing member 550 described above.

The positions of the latch portions 524 and 534 of the first and second latch devices shown in Fig. 18 are the same as the positions of the latch portions 524 and 534 of Figs. 17A and 17B, The auxiliary storage chamber 30 is in the opened state and the auxiliary storage chamber 100 is disposed at the inlet of the storage chamber 20.

At this time, the engaging pins 5247 and 5347 of the engaging portions 524 and 534 are located in the extended grooves located on the left side of the engaging guide grooves 112 and 122, and the engaging steps 112a and 122a formed on the front edge of the extended groove, And is restricted from moving forward.

The stoppers 111 and 121 are located in the stopper grooves 523 and 533 and the stopper grooves 523 and 533 surround the rear and the sides of the stoppers 111 and 121.

In this state, when the door 30 is separated from the auxiliary storage 100 and the user pulls the door 30, only the door 30 is pivoted forward and the auxiliary storage 100 is opened.

The engaging pins 5247 and 5347 are located in the extended grooves provided on the left side of the engaging guide grooves 112 and 122. Since the extended grooves are blocked by the engaging steps 112a and 122a, The engagement of the engagement pins 5247 and 5347 with the engaging steps 112a and 122a is restricted to move forward even when the engaging step 30 is opened forwards.

Therefore, the door 30 can be opened smoothly.

As shown in FIG. 19 (a), the latching parts 524 and 534 of the first and second latch devices are separated from the fixing member 550.

The engaging grooves 5242 and 5342 of the engaging portions 524 and 534 face forward and the state of surrounding the fixing pin 552 of the fixing member 550 is released, Can fall forward.

Thus, the door 30 and the auxiliary storage 100 can be separated from each other.

The motion guide portion 526 moves only by the pressing operation of the pressing portion 522. Since the pressing portion 522 is provided only in the first latch device, Needs to be prepared.

The insertion portion 5262 of the motion guide portion 526 is detached from the first insertion groove 5244 to guide the rotation of the latching portion 524.

The contact piece 5263 provided in the motion guide part 526 maintains contact with the pressing part 522 and the pressing part 522 can advance and rotate, The rotation of the engagement portion 524 can be caused.

The fixing member 550 is disengaged from the first and second guide supporters 510 and 540 as shown in FIG. 19 (b).

The insertion guide grooves 513 and 543 provided in the first and second guide supporting portions 510 and 540 guide the releasing movement of the fixing pin 552 of the fixing member 550 in a slanting shape.

Since the fixing member 550 adjacent to the first and second guide supporting portions 510 pivots while drawing a curve, it can be guided by the insertion guide grooves 513 and 543 formed in the oblique direction, Accordingly, the first and second guide supports 510 and 540 can be separated from the fixing member 540.

Although the process of separating the auxiliary storage room 100 and the door 30 from each other is described above, the process of coupling the auxiliary storage room 100 in the separated state is performed in the reverse order of the above-described process.

As described above, since the coupling and disconnection processes between the first latch device 520 and the fixing member 550 are substantially similar to the coupling and separation process between the second latch device 520 and the fixing member 550, 1 latch device 520 will be described with reference to the second latch device 530. [

In other words. The user pushes the door 30 in a state where the fixing member 550 and the first latch device 530 are separated as shown in Figure 17 (b) And enters the latch device 520.

The fixing member 550 is inserted into the insertion guide groove 5211 and pushes the first extension portion 5252 of the rotation limiting portion 525 backward.

The rotation restricting portion 525 rotates in the clockwise direction so that the insertion portion 5255 of the rotation restricting portion 525 is disengaged from the second insertion recess 5245 of the engaging portion 524 .

Thus, the latching portion 524 can rotate clockwise.

The fixing pin 552 of the fixing member 550 enters the engaging groove 5242 and pushes the engaging groove 5242 backward to rotate the engaging portion 524 in a clockwise direction.

When the locking part 524 rotates clockwise, the movement guide part 526 connected by the locking part 524 and the second elastic member 5292 is pulled.

Whereby the motion guide portion 526 rotates counterclockwise.

Therefore, the first insertion groove 5244 and the insertion portion 5262 of the motion guide portion 526 are close to each other.

When the fixing member 550 is completely inserted, the engaging groove 5242 of the engaging portion 524 faces the side, and the fixing pin 552 is surrounded by the engaging groove 5242 That's it.

The insertion portion 5262 of the motion guide portion 526 is inserted into the first insertion groove 5244 to limit the rotation of the engagement portion 526. [

Thus, the fixing member 550 is completely restrained by the engaging portion 524 and can be prevented from being disengaged in the forward direction.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, Changes will be possible.
