The surface 6 1 is multiplied by the inclined surface 60 of the hook receiving portion 37 and follows the inclined surface. Slide forward. At this time, the hook 4 3 resists the elastic thrust of the spring portion 4 5 and moves toward the rear of the box to determine the central 60 of the rear sub-shape. The tilted 60th -19- (15) 1241371 3 clockwise as shown in Figure 3 Rotate in the direction and engage the hook receiving portion 3 7 with the spring thrust of the spring portion 4 5 through the inclined surface 6 1 through the inclination 6 0 '. The hook 4 3 is engaged with the rear cover 2 by the hook receiving portion 3 7 and the hook 4 3. 6 For those who operate from the open state to the closed state, and automatically return to the engaged state from the unlocked state with the operating force, the front cover 25 and the rear cover 26 are locked to close without operations other than 26 after the closing operation. State person. As shown in Fig. 3, the rear end portion of the front holding member 35 is integrated into an eaves portion 62 corresponding to the restraining member. When the rear cover 26 is closed, the engaging portion 63 is engaged with the eaves portion 62 from below. This engaging portion 63 is integrally formed with the rear holding member 39, and is engaged with the eaves 6 at the same time as the inclined surface 6 1 of the hook 4 3 multiplied by the inclined surface 6 0 of the hook receiving portion 37 7. 2. That is, the eaves portion 62 is a person who presses the engaging portion 6 3 from above to prevent the top wall of the rear retaining member 39 from being elastically deformed upward by the spring thrust of the spring portion 45. The hook 43 suppresses the rear retaining member 3 9 The elastic deformation is maintained in a normal posture in which the hook receiving portion 37 can be engaged. According to the first embodiment, the outer cover 27 is divided into the front 25 and the rear cover 26, and the front cover 25 and the rear cover 26 are moved in opposite directions to each other, thereby opening and closing the entrance and exit 18 of the top cover 17. Therefore, the moving stroke of the front cover 25 and the moving stroke of the rear cover 26 are smaller than the size of the entrance / exit 18, so that the user can open / close the entrance / exit 18 with less burden. Since the front cover 25 and the rear cover 2 6 'are slidably provided, it is possible to eliminate the case where the cover 25 and the rear cover 26 protrude upward from the downstream cover 17 in the open state. Therefore, it is possible to eliminate the front cover 25 and the rear cover 26 from interfering with water pipes and the like of the tap water, so that the degree of freedom in setting the outer case 16 is improved. From the surface to the cover, the card is shaped as the receiving part. The cover is moved to the cover. -20- 1241371 (16) Set the front cover 2 5 and the back cover 2 6 into a belly shape. Therefore, when the “front cover 2 5 and the rear cover 2 6 slide along the guide rail 21,” the shape of the front cover 2 5 and the shape of the rear cover 2 6 changes along the curved path, so the front cover 2 5 and the rear cover 2 6 Sliding becomes smooth. Since the front cover 25 and the rear cover 26 are composed of a combination of the same parts (rotating pieces 2 8), the cost can be reduced compared to the case where the front cover 25 and the rear cover 26 are composed of a combination of different parts. ). Since the front cover 25 and the rear cover 2 6 are hidden in a state where they cannot be visually recognized in the open state, the appearance of the products in the open state of the front cover 25 and the rear cover 26 can be improved. Since the outer cover 27 is divided into the front cover 25 and the rear cover 26 at the central portion in the front-rear direction of the entrance / exit 18, the movement strokes of the front cover 25 and the rear cover 26 are the same. Since a transmission mechanism 5 6 ′ that reversely transmits the moving force of the front cover 25 to the rear cover 26 is provided, it is not necessary to individually operate the front cover 25 and the rear cover 26. A lock mechanism 46 is provided to lock the front cover 25 and the rear cover 26 to the closed state. Therefore, since the front cover 25 and the rear cover 26 are suppressed from moving in the closed state, the front cover 25 and the rear cover 26 can be prevented from receiving abnormal sounds caused by vibration during operation. When the lock between the front cover 25 and the rear cover 26 is released, the front cover 25 is moved from the closed state to the open state spontaneously. Therefore, there is no need for the user to directly perform the opening operation, so the opening operation of the front cover 25 becomes simple. -21-(17) 1241371 Utilizing the automatic control of 2 5 as the driving force for the spontaneous movement of the front cover 25. Therefore, an electric drive source for spontaneous movement of the front cover 25 and a mechanical drive edge such as a spring are not required, so the structure becomes simple. When the lock between the front cover 25 and the rear cover 26 is released, the front cover 2 5 slides from the closed state to the open direction under its own weight, and the rear cover 26 is opened from the closed state by the sliding force of the cover 25. Slide in the direction. Therefore, it is not necessary for the user to directly operate the back cover 26, so the opening operation of the back cover 26 becomes simple. In addition, the one-touch operation to release the lock between the front cover 25 and the back cover 26 is used to open the entrance / exit 18, so that the operation of entering / exiting the entrance / exit 18 becomes simpler. When the rear cover 26 is moved from the closed state to the open direction, it is placed on the gently inclined portion 23 of the guide rail 21, and when it is moved from the open state to the closed direction, it is lowered to the gently inclined portion 23. Therefore, when the user closes the operation cover 26, the operation force reduces the self-weight portion of the rear cover 26, so the burden when closing the operation cover 26 becomes small. Since the operator 5 8 for moving operation is provided on the rear cover 26, the user can close the entrance and exit 18 by placing his finger on the operator 5 8 and pulling the rear cover 26 forward. Therefore, it is easier to apply force than when the front cover 25 is pushed in to close the outside entrance 18, so the closing operation of the entrance 18 is simple. Since the operator 5 8 for moving operation is provided only on one side of the rear cover 2 6, the user can clearly confirm that only the rear cover 2 6 # is close enough to close the entrance and exit 18 of the top cover 17. Operation is required before moving the cover. Open the upper cover, use the rear side, and close the outside. -22- 1241371 (18) Place the operator 4 7 for unlocking the lock and the operation part 48 for the mobile operation. Therefore, the user can operate the operator 4 7 with the remaining fingers of the same hand in a state where the user puts his hand on the hand part 5 9 of the operator 5 8, which is convenient to use. The hook receiving portion 37 and the hook 43 have a hook shape having first and second claw portions 38 and 44 pointing upward and downward. Therefore, when the user's hand is placed on the rear holding member 39 in the closed state of the front cover 25 and the rear cover 26, and the external force acts from the top to the bottom, the second claw portion 44 is engaged with the first claw. Since the portion 38 moves in the direction, it is possible to prevent the front cover 25 and the rear cover 26 from being unintentionally slid in the opening direction due to the engagement of the two. When the hook 43 is brought into contact with both of the hook receiving portion 37 and the operator 4 7 in the engaged state, the hook 4 3 cannot be restricted to rotate. Therefore, it is possible to prevent the hook 43 from being rotated by vibration during operation, so that it is possible to prevent the front cover 25 and the rear cover 26 from being unintentionally moved by the engagement between the hook receiving portion 37 and the hook 43 due to vibration during operation. The feeling of sliding in the open direction arises. By engaging the engaging portion 63 of the rear holding member 39 to the eaves portion 62 of the front holding member 35, the elastic deformation of the rear holding member 39 is suppressed, and the hook 43 is prevented from interlocking with the elastic deformation of the rear holding member 39. The occurrence of abnormal posture. Therefore, the hook 43 can be reliably engaged with the hook receiving portion 37 according to the closing operation of the rear cover 26, so that the front cover 25 and the rear cover 26 can be linked to the closing operation of the rear cover 26 and can be reliably locked. The metal wire 53 is erected on the rear block 51 in a folded-back manner, and an upper part and a lower part are formed on the metal wire 53. The front cover 25 and the rear cover 26 are connected to the lower part and the upper part of the metal wire 53. Therefore, the transmission mechanism -23- (19) 1241371 5 6 can be miniaturized 'so that the degree of freedom in disposing the transmission mechanism 56 can be increased. In the first embodiment described above, both the front cover 25 and the rear cover 26 are hidden in the open state so that they cannot be visually recognized, but are not limited to this. For example, only one of the front cover 25 and the rear cover 26 is hidden. The structure. In the first embodiment described above, the front cover 2 5 and the rear cover 2 6 are stored in the outer box 16 in the open state so that they cannot be visually recognized, but it is limited to this, and the front cover may be hidden in the open state. 2 5 and back cover 2 6
