[Means for Solving the Problems]

 The present invention has been proposed to achieve the above-mentioned object, and the learning desk is attached to any of the learning table, a fitting, a leg, and a drawer of the learning desk. It is characterized by comprising human body detecting means for detecting that the human body has been attached to the body, and a lighting device which is turned on or off based on the human body detecting signal of the human body detecting means.

[0006]

[Action]

 According to the learning desk according to the above invention, when the learner attaches to the learning desk, the human body detecting means detects the state, and the lighting fixture is turned on based on the human body detection signal. When leaving, the lighting fixtures that were lit up until then are turned off. Therefore, learners of low age group such as infants and elementary school children do not need to turn on / off the manual switches as in the conventional case, and therefore, the visual acuity is not deteriorated due to forgetting to turn on. Not only that, but it is possible to sufficiently prevent unnecessary power consumption due to forgetting to turn it off.

【Example】

 Hereinafter, an embodiment of a learning desk according to the present invention will be described in detail with reference to the drawings. Since the learning desk according to this embodiment is constructed by attaching a sensor to a conventional learning desk, common members will be described using the same reference numerals.

In this learning desk 1, as shown in FIG. 2, a human sensor 11 is attached to an inner fitting plate 10. The human sensor 11 is attached to a position facing the thigh of the learner S when the learner S such as an infant shown by a broken line in the figure sits on the chair C and contacts the learning desk 1. It is a so-called retroreflective sensor in which a light emitting element and a light receiving element (not shown) are provided inside, and sensor light such as infrared rays emitted from the light emitting element is used by the learner S. It is detected that the learner S has attached to the learning desk 1 by reflecting the light around the thighs and entering the light receiving element. The motion sensor 11 is connected to a lighting fixture 5 attached to a bookshelf 4 fixed on the top plate 3 of the desk body 2. Due to the presence of the learner S 1 by the motion sensor 11, The lighting fixture 5 is configured to be turned on. That is, in the learning desk 1, when the human body is detected by the human sensor 11 in step st1 as in the flowchart shown in FIG. 3, the lighting fixture 5 which is an electric light is turned on in step st2, and the reverse operation is performed. When there is no human body detected in, the electric light is not turned on and remains turned off. In this case, the manual switch 5a attached to the bookshelf 4 is turned on.

Therefore, according to the learning desk 1 configured as described above, the lighting fixture is automatically detected by the detection of the learner S by the human sensor 11 without performing any on / off operation of the manual switch 5a. Since 5 is turned on or off, it is possible to effectively prevent the deterioration of the visual acuity of learners S in the low age group such as infants, and to effectively prevent the wasteful consumption of electric power due to forgetting to turn it off. can do.

In the learning desk 1 according to the above-described embodiment, the so-called retroreflective type human sensor 11 is used as the human body detecting means constituting the present invention. However, as shown in FIG. The light emitter 20 is attached to the inner fitting plate 10 and the light receiver 21 is attached to the side plate 16 facing the inner fitting plate 10, and the sensor light 22 emitted from the light emitter 20 to the light receiver 21 is the learner S. It is also possible to use a sensor of the type that detects that the learner S is attached to the learning desk 1 by being cut off around the thighs.

Further, according to the present invention, not only the human sensor 11 described above but also an illuminance sensor (not shown) for detecting illuminance is attached to, for example, the top plate 3 of the learning desk 1, and the illuminance sensor is provided with a timer. May be connected. That is, as shown in the flowchart in FIG. 5, first, in step st11, the presence sensor 11 detects the presence of the human body (the state in which the learner S is attached to the learning desk 1), and in step st12, the illuminance sensor detects the presence of the human body. It is detected whether or not the top plate 3 has a predetermined brightness, and only when the brightness is not the predetermined brightness (when it is not the minimum brightness necessary for learning), the electric lamp which is the lighting fixture 5 in step st13. Is turned on, and even if the presence sensor 11 detects the presence of the human body in step st12, the timer turns off the lighting fixture 5 until a predetermined time elapses in step st14. First, the lighting device 5 is turned off in step st15 after the elapse of a predetermined time in step st14. Cormorants are configured comprising may be a learning desk 1. According to the learning desk 1 having such a configuration, even when the learner S is simply attached to the learning desk 1 by the motion sensor 11, the predetermined brightness (the minimum brightness required for learning is set). In this case, since the lighting fixture 5 is not turned on, it is possible to further suppress wasteful power consumption as compared with the learning desk according to the above-described embodiment. Further, in the learning desk 1 having such a configuration, even if the presence of the human body is no longer detected by the human sensor 11, the lighting device 5 is not turned off until a predetermined time (for example, 10 minutes) has elapsed. Therefore, when the user leaves the desk 1 for an extremely short time, or sits on a rotatable chair (not shown) for learning, the chair is rotated to face the opposite side of the desk 1 and the book is read from the nearby bookshelf. Even if it is taken out, it is not turned off, so it is possible to effectively avoid power consumption by repeating lighting and turning off.

As described above, according to the learning desk 1 according to the above-described embodiment, it is possible to effectively prevent the deterioration of the visual acuity due to the learner forgetting to turn on the lighting fixture 5, and the power consumption due to forgetting to turn it off. This can be effectively prevented, and in particular, by using not only the human body detecting means but also the illuminance detecting means and the timer as constituent elements, it is possible to further suppress unnecessary power consumption. In the above embodiment, the human sensor 11 serving as the human body detecting means constituting the present invention is attached to the inner fitting plate 10 for illustration, and this human body detecting means is at least for the learner. At the position where the state attached to the learning desk can be detected, not only the inner fitting plate 10 but also the bottom plate of the drawer 13 attached to the side plate 16, the leg portion not shown, or the lower surface side of the top plate 3, for example. It may be attached to other parts such as.

[0013]

[Effect of device]

 As is clear from the above description of the embodiments of the present invention, according to the learning desk according to the present invention, when the learner attaches to the learning desk, the state is detected by the human body detecting means, and based on this detection signal. While the lighting equipment is turned on, the lighting equipment that has been turned on up to that point is turned off when the user leaves the learning desk. Therefore, it is not necessary for low-age learners such as infants and elementary school children to turn on / off the manual switch as in the conventional case, and thus the visual acuity is not deteriorated due to forgetting to turn on the lighting equipment. Not only that, but it is possible to sufficiently prevent unnecessary power consumption due to forgetting to turn it off.
