BEST MODE FOR CARRYING OUT THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on an example of an embodiment. In FIG. 1, reference numeral 12 in the figure denotes a backrest having a built-in massage mechanism, and the backrest 12 is a frame including a seat 19 and an armrest 13. It is attached to 9 to be able to recline freely. And the receiving part 14 which receives the optical signal from the operation device 10 provided with the transmitting part which transmits the optical signal is provided in a portion located below the armrest 13 and on both sides of the seat 11 in the frame 9. .
[0013]
In the illustrated massage machine in which the receiving unit 14 is disposed at such a position, when the user operates the operating device 10 with his / her hand, the optical signal output from the transmitting unit of the operating device 10 is Reaches the receiving unit 14 without being blocked by the user's arms or hands. In particular, in the illustrated example in which the receiving portion 14 is provided on both sides of the seat portion 11 and near the rotation axis of the backrest 12 which can be reclined, as shown in FIG. 2, the backrest 3 is reclined. Even in this state, the positional relationship and the distance between the operating device 10 and the receiving unit 14 hardly change, so that stable optical signal transmission and reception can be performed.
[0014]
FIG. 3 shows the details of the receiving unit 14. Since the wall 14b that reflects the optical signal from the operating device 10 toward the light receiving sensor 14a is provided near the light receiving surface, the receiving unit 14 Reception is more reliable. In the figure, reference numeral 14c denotes a protective cover having translucency, and 14d denotes a circuit board.
[0015]
When an operation device 15 is provided in addition to the operation device 10 which is a wireless remote controller, the operation device 15 may be provided adjacent to the receiving unit 14 as shown in FIG. When the operation device 10 is lost, an operation instruction can be given by the operation device 15. In the figure, reference numeral 16 denotes a display unit. By displaying the operation state on the display unit 16, the transmission / reception state with the operation device 10 can be confirmed.
[0016]
FIG. 5 shows an operation device 10 that is a wireless remote controller that can be used as a stationary operation device. The operation device 10 also has a transmitter on the lower surface side. A recess 17 for accommodating the operating device 10 is provided in the armrest 13, and an optical signal from a transmitting unit provided on the lower surface of the operating device 10 is directed to the receiving unit 14 at the bottom of the recess 17. The light-transmitting portion 18 is provided.
[0017]
FIGS. 6 and 7 show a specific example of the operating device 10 which can be used even when it is installed on the armrest 13 described above. A transmitter 19 is provided on the lower surface side of the upper part for use when installed on the armrest 13. In the transmitting section 19, the light emitting element is provided obliquely downward so that an optical signal can be transmitted toward the receiving section 14 when the switches are operated while holding the operating device 10 in a hand.
[0018]
When the operation device 10 includes the display unit 21 formed of a liquid crystal display or the like, it is preferable that the transmission units 19 and 20 be installed near the display unit 21 or on the back side of the display unit 21. .
