  In the lift sensor storage space 5b, a control device 20 is provided as control means in the present invention for driving and controlling the motor 13. The control device 20 is connected to the motor 13, the light emitting elements 9a, 16a, and 17a, the light receiving elements 9b, 16b, and 17b, and the limit switches 11 and 11 by wiring (not shown). Note that the control device 20 has a built-in timer circuit (not shown).

  Next, the rack lifting / lowering process executed by the control device 20 in the present embodiment will be described based on the flowchart of FIG.

  First, in step Sa01, the control device 20 determines whether or not the first lifting sensor 16 and the second lifting sensor 17 have simultaneously detected the detected object 18 (user's hand). When the first lift sensor 16 and the second lift sensor 17 simultaneously detect the detected object 18 (user's hand), the control device 20 ends the shelf lifting process. If the 1st raising / lowering sensor 16 and the 2nd raising / lowering sensor 17 are not detecting the to-be-detected body 18 (user's hand) simultaneously, it will progress to the step of Sa02.

  In step Sa02, the control device 20 determines whether or not the first lift sensor 16 has detected the detected object 18. If the 1st raising / lowering sensor 16 has detected the to-be-detected body 18, the control apparatus 20 will start time measurement of predetermined time by a time measuring circuit (not shown), and will progress to the step of Sa03. If the 1st raising / lowering sensor 16 has not detected the to-be-detected body 18, it will progress to the step of Sa09.

  In step Sa03, the control device 20 determines whether or not the second lift sensor 17 has detected the detected object 18. If the second lift sensor 17 detects the detected object 18, the control device 20 proceeds to step Sa04. If the second lift sensor 17 has not detected the detected object 18, the process proceeds to step Sa08.

  In step Sa08, the control device 20 determines whether or not a predetermined time has elapsed with reference to a timer circuit (not shown). If the predetermined time has elapsed, the control device 20 ends the shelf lifting process. If the predetermined time has not elapsed, the process proceeds to step Sa03. The predetermined time is suitably set in the range of about 0.1 seconds to 1 second depending on the operation speed of the user's hand.

  Further, when the second lift sensor 17 detects the detected object 18 in the step of Sa03, in the step of Sa04, the control device 20 performs an ascending process for raising the shelf 5 toward the storage position. Proceed to step.

  In step Sa05, the control device 20 determines whether or not the stored item sensor 9 detects the stored item 3. The control device 20 proceeds to step Sa06 if the stored item sensor 9 has not detected the stored item 3, and proceeds to step Sa07 if the stored item sensor 9 has detected the stored item 3.

  In step Sa06, the control device 20 determines whether or not the limit switches 11 and 11 are in contact with the upper ends of the slide rails 7 and 7. If the limit switches 11 and 11 are in contact with the upper ends of the slide rails 7 and 7, the control device 20 proceeds to step Sa07. If the limit switches 11, 11 are not in contact with the upper ends of the slide rails 7, 7, the process proceeds to step Sa04.

  In step Sa07, the control device 20 performs an ascending / stopping process for stopping the shelf 5 at the current height position (or storage position), and ends the shelf lifting / lowering process.

  In particular, after the stored item sensor 9 detects the stored item 3 in the step of Sa05, the rising of the shelf body 5 is stopped halfway by the rising stop process in the step of Sa07, so that the storage projecting from the inside of the shelf unit 5a is performed. The object 3 is prevented from being sandwiched between the outer box 4 and the shelf 5.

  On the other hand, when the first lift sensor 16 does not detect the detected object in the step of Sa02, the process proceeds to step Sa09, and the control device 20 determines whether the second lift sensor 17 detects the detected object 18. Determine. If the 2nd raising / lowering sensor 17 has detected the to-be-detected body 18, the control apparatus 20 will start time measurement of predetermined time by a time measuring circuit (not shown), and will progress to the step of Sa10. If the 2nd raising / lowering sensor 17 has not detected the to-be-detected body 18, a shelf raising / lowering process will be complete | finished.

  In step Sa10, the control device 20 determines whether or not the first lift sensor 16 has detected the detected object 18. If the first lift sensor 16 detects the detected object 18, the control device 20 proceeds to step Sa11. If the 1st raising / lowering sensor 16 has not detected the to-be-detected body 18, it will progress to the step of Sa15.

  When the first lift sensor 16 does not detect the detected object 18 in the step Sa10, in the step Sa15, the control device 20 refers to a timing circuit (not shown) to determine whether or not a predetermined time has elapsed. Determine whether. If the predetermined time has elapsed, the control device 20 ends the shelf lifting process. If the predetermined time has not elapsed, the process proceeds to step Sa10.

  When the first lift sensor 16 detects the detected object 18 in the step of Sa10, in the step of Sa11, the control device 20 performs a lowering process for lowering the shelf body 5 toward the use position. Proceed to step.

  In step Sa12, the control device 20 determines whether the first lifting sensor 16 or the second lifting sensor 17 has detected the detected object 18. If the first lift sensor 16 or the second lift sensor 17 has not detected the detected object 18, the control circuit 20 proceeds to step Sa13. If the 1st raising / lowering sensor 16 or the 2nd raising / lowering sensor 17 has detected the to-be-detected body 18, it will progress to the step of Sa14.

  In step Sa <b> 13, the control device 20 determines whether or not the limit switches 11 and 11 are in contact with the lower ends of the slide rails 7 and 7. If the limit switches 11 and 11 are in contact with the lower ends of the slide rails 7 and 7, the control device 20 proceeds to step Sa14. If the limit switches 11, 11 are not in contact with the lower ends of the slide rails 7, 7, the process proceeds to step Sa11.

  In step Sa14, the control device 20 performs a descent stop process for stopping the shelf 5 at the current height position (or use position), and ends the shelf lifting process.

  In particular, after the first elevating sensor 16 or the second elevating sensor 17 detects the detected object 18 in the step of Sa12, the descent of the shelf 5 is stopped halfway by the descent stop process in the step of Sa14. Since it is possible to detect that a part of the user's body or tableware is arranged at a lower position of the body 5, the shelf 5 is lowered to the part of the user's body or tableware. Safety under the shelf 5 can be ensured so that the body 5 does not contact.

  It should be noted that in the case where the rising of the shelf 5 is stopped halfway by the rising stop process in the step of Sa07 and in the case where the lowering of the shelf 5 is stopped halfway by the lowering stop process in the step of Sa14, Sa01 is again performed. By repeating the shelf raising / lowering process from the step, the shelf 5 can be raised and lowered to the use position or the storage position.

  As described above, the hanging cabinet 1 in the present embodiment includes detection means (first and second elevating sensors 16 and 17) for detecting the detected object 18 that is close to the shelf body 5 in a non-contact manner. The detected object 18 arranged at a plurality of first detection positions A1 and second detection positions A2 separated from each other can be detected, and the control device 20 can detect each of the first detection positions A1 and Based on the time-series change of the detection state of the detected object 18 at the second detection position A2, the moving direction of the detected object 18 is identified, and the ascending / descending direction of the shelf 5 is selected according to the moving direction. The user's hand is detected by the detecting means when the user brings the hand as the detected object 18 close to the shelf 5 by moving the hand up and down, and further when the user moves the hand, the user moves away from each other. First detection position A1 and second detection position A And the control device 20 determines the moving direction of the user's hand based on the time-series change of the detection states of the first detection position A1 and the second detection position A2. It becomes possible to identify, the operation of raising and lowering the shelf according to the movement of the user's hand can be selected as appropriate, and the raising and lowering operation of the shelf 5 can be freely performed according to the user's intention action Thus, it is possible not only to prevent an erroneous operation due to a user's operation mistake, but also to move up and down without touching the operating device or the shelf 5 itself. When the detected object is detected only at the first detection position A1 or the second detection position A2, or when the detected object is detected simultaneously at the first detection position A1 and the second detection position A2. Since the shelf body 5 is neither raised nor lowered, even if the user carelessly approaches the shelf body 5, the shelf body 5 is not operated without permission, and the shelf body 5 is prevented from malfunctioning. Can do.

  In addition, the first detection position A1 and the second detection position A2 are spaced apart in the vertical direction, and the control device 20 determines that the lifting / lowering direction of the shelf 5 depends on the moving direction of the detection target 18. Thus, when the user raises and lowers the hand as the detected body 18 in the vicinity of the shelf 5, the moving direction of the user's hand coincides with the elevation direction of the shelf 5. Can move the shelf 5 up and down by an intuitive operation of moving the hand up and down.

  The detection device 20 includes a first lift sensor 16 and a second lift sensor 17, and the first lift sensor 16 and the second lift sensor 17 are arranged at the first detection position A1 and the second detection position A2. By being arranged so that the detection body 18 can be detected, the first elevation sensor 16 and the second elevation sensor 17 are arranged at the first detection position A1 and the second detection position A2 corresponding to the first elevation sensor 16 and the second detection position A2, respectively. Therefore, the moving direction of the user's hand can be identified using the first lifting sensor 16 and the second lifting sensor 17 having a simple configuration at low cost.

  In addition, the first detection position A1 and the second detection position A2 are located below the shelf 5, so that when the user puts in / out the stored item 3 to / from the shelf 5, The first elevating sensor 16 and the second elevating sensor 17 do not mistakenly detect a hand or the like, and the malfunction of the shelf 5 can be prevented.

  In addition, the storage device 9 that detects the storage item 3 protruding from the shelf 5 is provided, and the control device 20 stops the motor 13 based on the detection of the storage item 3 by the storage item sensor 9. When the shelf 5 is raised between the use position and the storage position, the storage sensor 9 detects and controls the storage item 3 even if the storage item 3 such as tableware protrudes from the shelf 5. The apparatus 20 stops the drive of the motor 20, and it is possible to prevent the stored item 3 from being damaged or the stored item 3 from falling from the shelf.
