  • the control unit 62 also transmits a position saving command to all the beacon units 51.
  • the light emission control unit 58 of the rotary light unit 51 which is turned off in response to the light emission stop signal, sets the position of the light in the rotation direction S when the light is turned off (hereinafter, referred to as “light emission end position”) in response to the position saving command. Temporarily stored in the buffer (not shown).
  • the light emission control unit 58 of the rotary light unit 51 that did not turn off this time continuously temporarily stores the light emission end position at the time of the previous turn-off in its own buffer in response to the position saving command.
  • the light emission control unit 58 restarts the light emission from the light emission end position temporarily stored in its own buffer. After that, when the rotary light unit 51 is turned off, the light emission control unit 58 updates the light emission end position in the buffer with the latest information in response to the position saving command.
  • control unit 62 may temporarily store the light emission end position of the light emitting unit 51 that has been turned off in the buffer 66 by associating it with the unit ID (which may be light emission color information) of the rotary light unit 51. Good (see Figure 7).
  • the light emission end position may be transmitted from the extinguished rotary light unit 51 to the control unit 62, or may be set to the time difference between the transmission timing of the light emission start signal and the transmission timing of the light emission end signal, and the rotation cycle of the rotary light unit 51. Based on this, it may be calculated by the control unit 62.
  • the control unit 62 transmits the light emission start signal to the beacon unit 51 next time, the light emission start position of the table T (see FIG. 4) for the unit ID whose light emission end position is temporarily stored in the buffer 66. ), The emission end position is transmitted to the rotary lamp unit 51. Therefore, the rotary lamp unit 51 to which the light emission end position is transmitted restarts the light emission from the light emission end position. After that, when the rotary light unit 51 is turned off, the control unit 62 updates the corresponding light emission end position in the buffer 66 with the latest information.
  • each rotary light unit 51 starts light emission from the initial light emission start position registered in the table T as described above.
  • each rotary light unit 51 emits light from the previous light emission end position.
  • the information in the buffer 66 may be cleared, and in that case, in the first light emission after the power of the laminated rotary lamp 50 is turned on again, each rotary lamp is used.
  • the unit 51 starts light emission from the initial light emission start position registered in the table T.
  • each rotary lamp unit 51 may start light emission from the light emission start position each time.
  • the control unit 62 can make these beacon units 51 emit light asynchronously even if only one of the emission start position and the rotation cycle is different.
  • these rotation cycles may be set so that the least common multiple is large. Therefore, the difference in the rotation speed of the light between the adjacent rotation positions (see FIG. 2), that is, in the case of 1/48 rotation in the present embodiment, is, for example, 1 ms between the at least two rotary lamp units 51. It is good to secure a few ms. As a result, it is possible to minimize the phenomenon that the light momentarily coincides with each other in the rotation direction S between the at least two beacon units 51 having different rotation cycles.
  • the plurality of rotary lamp units 51 having the same emission color information emit synchronous light as the same genus unit 51A, but the rotary lamp unit 51 having common attributes other than the emission color information is designated as the same genre unit 51A. Synchronous light emission may be performed. Other attributes include the positional relationship of each beacon unit 51 and the unit ID. As an example, all the rotary lamp units 51 of the third stage and above can be regarded as the same genus unit 51A having a common positional relationship. As another example, all the rotating light units 51 having a unit ID of 3 or later can be regarded as the same genus unit 51A having a common unit ID. The user may be able to select the beacon unit 51 to be the unit 51A of the same genus by operating the setting unit 64 or the like.
  • the plurality of units 51A belonging to the same genus emit light in synchronization, but all the rotating light units 51 including the unit 51A belonging to the same genre may emit light asynchronously.
  • the third-stage and fourth-stage rotary lamp units 51 which are common because the emission color is red, emit light asynchronously, for example, because the emission start positions are different. (See arrows Y3 and Y4).
  • these beacon units 51 May be emitted asynchronously.
  • each rotary lamp unit 51 of the laminated rotary lamp 50 in the present embodiment the light sources 57A to 57F in the light emitting unit 55 are turned on in order, so that the light seems to rotate in a pseudo manner.
  • Such a flow-type laminated rotary lamp 50 can also be used as a signal indicator lamp by turning on, blinking, or flashing all or part of the light sources 57 in each rotary lamp unit 51 all at once.
  • Each rotating light unit 51 is not limited to the configuration in which the LED light sources 57 described in the present embodiment are turned on in order, and may be a motor type configuration in which the reflecting mirror disclosed in Patent Document 1 is rotated by a motor. ..
  • the control unit 62 of the base unit 53 controls the light emission of the light emitting unit 55 of the rotating light unit 51 via the light emitting control unit 58 of the rotating light unit 51, but the light emitting control unit 58 is omitted. Therefore, the control unit 62 may directly control the light emission of the light emitting unit 55 of each beacon unit 51. Further, the control device 101 may be regarded as a part of the laminated rotary lamp 50. In this case, the control device 101 mainly controls the light emission of each beacon unit 51 of the laminated beacon 50.
  • the control unit (not shown) on the master side in IO-Link is the respective rotating lamp unit 51 of the laminated rotary lamp 50. You may control the light emission of. In this case, the control unit may be regarded as a part of the laminated rotary lamp 50.
