BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baggage receiving and receiving device for delivering parcels, etc., to recipients, for example.

0002

[Background Art] Recently, in apartment complexes such as condominiums, a large number of lockable luggage storage boxes are centrally installed, and delivery companies and sellers such as supermarkets have to select and deliver these luggage storage boxes. After storing the luggage, the recipient at the apartment complex unlocks the luggage storage box and receives the luggage.
Alternatively, a package sending and receiving device has been developed in which residents of apartment complexes store packages to be shipped in a luggage storage box and lock it, and a contracted delivery company unlocks the luggage storage box and retrieves the luggage inside. has been done.

[0003] Here, in order to check the presence or absence of luggage inside the luggage storage box without performing a troublesome unlocking operation, the method shown in FIG.
As shown in FIG. 2, light emitting elements 7 are arranged on the entrance side, central part, and back side of the ceiling surface 4 of the luggage storage box 1 having a lockable door 2, and light emitting elements 7 are arranged on the entrance side, central part, and back side of the bottom surface 3. A light-receiving element 8 is disposed on the outer surface of the door 2, and a handle 9 and a display unit 10 connected to the light-receiving element 8 are provided on the outer surface of the door 2. It is determined that the luggage 15 is not stored in the storage box 1, and when the light receiving element 8 does not receive the light emitted from the light emitting element 7, it is determined that the luggage 15 is stored in the luggage storage box 1. There is something I did.

0004

[Problems to be Solved by the Invention] There are various sizes of luggage 15 to be stored in the luggage storage box 1, and as shown by the imaginary lines in FIG. Not constant. For this purpose, conventionally, a plurality of pairs of light emitting elements 7 and light receiving elements 8 are arranged in a distributed manner, and the presence or absence of the luggage 15 is detected by one of the light receiving elements 8. However, since the number of light emitting elements 7 and light receiving elements 8 increases, the cost increases.

[0005]

[Means for Solving the Problems] The present invention provides a luggage storage box having a lockable door, a reflective surface disposed on opposing inner surfaces of the luggage storage box, and a reflective surface provided at an end of the luggage storage box. a light emitting element that is fixed and emits a light beam at a predetermined angle of incidence with respect to the reflective surface; It is composed of a light-receiving element fixed to the end of the baggage storage box opposite to the element, and a display section connected to the light-receiving element and fixed to the outer surface of the baggage storage box.

[0006]

[Operation] Changes in the output of the light receiving element are displayed on the display, but if there is no luggage in the luggage storage box, the light emitted from the light emitting element provided at one end of the luggage storage box will be directed to the opposite direction. The light is alternately reflected by the reflector and incident on the light receiving element provided at the other end of the luggage storage box. Additionally, if there is luggage in the luggage storage box, the optical path from the light emitting element to the light receiving element will be blocked by the luggage no matter where in the luggage storage box the luggage is stored, and the amount of light received by the light receiving element will be significantly reduced. . Thereby, the presence or absence of cargo is detected by the pair of light emitting element and light receiving element, and therefore it is possible to reduce costs.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 3. Components that are the same as those described in FIG. 4 are designated by the same reference numerals, and description thereof will be omitted. Reflective surfaces 5 and 6 are provided on substantially the entire area of the opposing inner surfaces of the luggage storage box 1, that is, the bottom surface 3 and the ceiling surface 4. Furthermore, one light emitting element 7 that emits a light beam at a predetermined angle of incidence with respect to the reflective surface 5 of the bottom surface 3 is fixed to one end of the ceiling surface 4 of the luggage storage box 1 on the entrance side. At the other end of the side, a light emitting element 7
One light receiving element 8 located near the end of the optical path of the light beam emitted from the mirror and reflected from the reflecting surfaces 5 and 6 is fixed.

Next, as shown in FIG. 3, two comparators 12 and 13 having different reference voltages are connected to the output side of the amplifying section 11 which outputs the light receiving element 8.
These comparators 12 and 13 are connected to the display section 10 via an OR gate 14.

In such a configuration, when there is no luggage in the luggage storage box 1, as shown in FIG.
Light emitted from the light emitting element 7 provided at one end is reflected alternately by the opposing reflectors 5 and 6 and enters the light receiving element 8 provided at the other end of the luggage storage box 1. In addition, as shown in FIG. 1, when a baggage 15 is stored in the baggage storage box 1, the optical path 16 from the light emitting element 7 to the light receiving element 8 is set no matter where the baggage 15 is placed. The light is blocked by the luggage 15, and the amount of light received by the light receiving element 8 is significantly reduced. As a result, the pair of light emitting element 7 and light receiving element 8 detect the presence or absence of a package, thereby making it possible to reduce costs.

[0010] Also, the reflective surface 5
, 6 has a high reflectance, but in rare cases, the reflective surfaces 5, 6
Luggage 1 wrapped in a package with a reflectance higher than that of
5, or there is also a package 15 with a highly reflective label affixed to the top of the package. However, in this example,
The output of the light receiving element 8 is amplified by the amplifier 11, and if the value is determined to be less than the lower limit value determined by the two comparators 12 and 13, it is detected as a normal baggage 15, and the upper limit value (reflective surface If it is determined that the output value is slightly higher than the output of the light receiving element 8 when receiving the light beam reflected by the reflective surfaces 5 and 6, the package 15 is detected as having a reflectance higher than that of the reflective surfaces 5 and 6. Ru.

In the embodiment described above, the reflective surfaces 5 and 6 were provided on the bottom surface 3 and the ceiling surface 4 of the luggage storage box 1. Reflective surfaces 5 and 6 may be provided on the inner surfaces of the sides and the inner surface of the door 2.

Effects of the Invention The present invention provides a luggage storage box having a lockable door, a reflective surface disposed on opposing inner surfaces of the luggage storage box, and a reflective surface fixed to an end of the luggage storage box. a light emitting element that emits a light beam at a predetermined angle of incidence with respect to the reflective surface; and a light emitting element located near the end of the optical path of the light beam that is emitted from the light emitting element and alternately reflected by the reflective surface and opposite to the light emitting element. The structure is composed of a light-receiving element fixed to the end of the luggage storage box on the side, and a display unit connected to the light-receiving element and fixed to the outer surface of the luggage storage box, so changes in the output of the light-receiving element can be displayed. However, when there is no luggage in the luggage storage box, the light emitted from the light emitting element provided at one end of the luggage storage box is reflected alternately by the opposing reflectors, and the light is reflected back to the luggage storage box. The light is incident on the light-receiving element provided at the other end, and if there is luggage in the luggage storage box, the optical path from the light-emitting element to the light-receiving element will be the same as that of the luggage no matter where in the luggage storage box the luggage is stored. As a result, the amount of light received by the light-receiving element is significantly reduced, and the pair of light-emitting element and light-receiving element detects the presence or absence of cargo, which has the effect of reducing costs.
