2. Description of the Related Art In a locker device provided with an electric lock,
It can be said that the determination of the presence or absence of the baggage inside the baggage by the baggage sensor is indispensable to prevent the control unit from depositing the baggage repeatedly in the locker containing the baggage. A conventional luggage sensor of this type generally uses a photoelectric sensor as shown in FIGS. 3A to 3F. When light is blocked, the storage state of the luggage is indicated. Is output to the control unit. In A, a transmissive optical sensor including a light emitting element 2 and a light receiving element 3 as light sources is provided on both sides of the locker 1, and the detection position is on a low line when viewed from the locker opening. However, thin envelopes and the like cannot be detected. B is a transmission type optical sensor 4 comprising a light emitting element 2 and a light receiving element 3 above and below the locker 1.
However, since it is provided on the bottom plate of the locker 1, not only the drawback that accurate operation is liable to be hindered by dust and dirt is recognized, but also a detection line on a line passing up and down is formed. However, there is a drawback that an object placed on the side cannot be detected. C is a combination of both A and B, and can detect a package stored almost completely inside. However, the use of two transmissive optical sensors 4 not only doubles the cost of parts, but also complicates assembly. D uses a regression reflection type optical sensor 5, in which the integrally formed light projecting element 2 and light receiving element 3 are arranged in the same direction, a regression mirror 6 is provided on the opposite surface, and the difference in reflected light due to luggage. It is to detect. This may be a malfunction due to reflection from the package, that is, output that there is no package. E is a reflection-type optical sensor 7, which has a structure in which the integrally formed light projecting element 2 and light receiving element 3 are arranged in the same direction, and detects the presence of a load when the load is shielded or reflected at the tip. It has become. It is susceptible to dust and dirt, and may malfunction due to scratches on the cover. F has a diffusion plate 8 provided on the front surface of the light receiving element 3 based on the transmission optical sensor 4 of B.
Although it seems that the detection is in the form of a plane and the accuracy is improved, the diffusion plate 8 is damaged by taking in and out of the baggage, and malfunctions are likely to occur due to dust and dirt. FIG.
G is for detecting the presence or absence of the baggage by the weight sensor 9, and specifically, the switch is turned on by the weight of the baggage by the pressure sensor. This could not be detected as light.

[0003]

In the conventional luggage sensor, the internal resistance of the light receiving element is changed by a change from a state without a luggage (transmitted light or reflected light) to a state with a luggage (light shielding or reflected light). This is amplified and input to the control unit to determine the presence or absence of a package.

[0004] In order to determine the presence or absence of a package by such a method, a sensor is operated for 24 hours to enable a locker to be used all day and to cope with theft or the like. However, in a locker device for parcel delivery luggage for a single-family house or a locker device for an apartment house, the cost of electricity is relatively heavy as a maintenance cost. Further, in some cases, since the controller is installed outdoors, it has been desired that the control unit be operated by a dry battery or a solar battery in order to avoid a complicated electric wiring, thereby achieving a power saving type.

[0005]

Means for Solving the Problems In order to solve such problems, the present invention provides a box in which external light does not enter in a normal state, and the inner surface is made of a material or color which is easy to absorb light. or the stored personal identification number input from the numeric keypad section, having a electric lock to unlock when matched against the stored memory contents to the controller insert the ID card
Which was equipped with a door that, a load sensor for detecting the presence or absence of an article in the box, the upper part provided with a reflective optical sensor in the box, door even if unlocking command signal from the control unit Is temporarily stored in the storage unit, then the data from the closing signal of the door after the door is opened and operated is compared with the data temporarily stored last time, It is characterized in that it is configured to detect the package as moving and erase the previous data and temporarily store the next data, and the package sensor is basically used by the delivery person or resident of the parcel delivery package. It could be activated only when operating.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A locker device includes a locker 10 having a normally closed electric lock K, a numeric keypad 11, a card reader 12, and a CPU.
And a power source 14 such as a dry battery or a solar battery.

[0007] The electric lock K is normally are locked in the引止pieces and dead bolt of the locking mechanism by unlocking signal from the control unit release opens Ri by the driving means such as a solenoid, or lightly pulling the handle The door 10a can be pushed to open the door 10a. The door 10a is automatically locked when the door 10a is closed after the door 10a is opened and the luggage is operated.
Unlocking the electric lock K, i.e., open signal of the opening-closing door 1 0 a is box selection when empty, the operation of unlocking buttons, magnetic card, the operation of the ID card and unlock button etc. IC cards, luggage This is based on an ID card such as a key, a numeric keypad, or a magnetic card when B is stored.

[0008] is the locking of the door 1 0 a hand, out due automatic locking by pressing manual after a door is open 1 0 a, close signal of the opening and closing door 10a when the automatic locking at the same time It is.

The luggage sensor 16 used in the present invention is basically a reflection type photomicrosensor to which a storage unit 17 is added. The luggage sensor 16 is the locker 10
LED above the ceiling, ie above the ceiling or side plate
Light emitting element 16a such as a lamp and silicon or Cd
The light receiving element 16b and an amplifier i.e. Zohaba portion 16c made of s cells are those formed by connecting an electronic circuit to the sensor modules together. The inner surface of the locker 10 on which light is projected is made of a color (black) or a material having a minute reflectance. This is to make it easier to detect the reflectance based on the presence or absence of the load, since the detection is performed based on the difference in reflectance.

Here, the operation of the luggage sensor 16 will be described with reference to FIG. When the electric lock K is unlocked by the unlocking output of the locker 10 by driving of a solenoid or the like, an opening / closing door opening signal thereof is input to the control unit 13 and a command is issued from the control unit 13 to be described later by the synchronization unit 16d. Comparison part 1
6f is turned on, and at the same time, the light emitting element 16a
Is turned on to project light inside the locker 10. Light receiving element 16
b denotes an electric signal that receives a weak reflection of light from the light projecting element 16a, and this electric signal is amplified by the amplifier 16c.
The comparator 16f converts the analog signal into a digital signal, and at the same time compares the magnitude of the signal with the comparator 16f. Conventionally, a reflectance to be compared (reflectance in a state where there is no luggage) is assumed in advance, and it is determined that there is a luggage if the reflectance is larger than this. In the present invention, the previous reflection is determined by the amplification unit 16c. The signal is amplified, converted to an analog signal by the comparison unit 16f, and temporarily stored in the storage unit 17,
The movement of the package is detected in comparison with the stored contents, and the presence or absence of the package is determined.

Here, the use of the locker 10 and the function of the luggage sensor 16 will be specifically described as follows. When the delivery person confirms the absence of the resident,
By operating a D card or a delivery button, the open / close door 10a of the empty locker 10 is unlocked. At this time, door 1
0a is a state in which the handle can be opened by pulling the handle with the handle closed. At this time, a command is issued from the control unit 13 (a pulse is immediately issued), and the output unit 16e and the comparison unit 16f are turned on.
A current flows from the output unit 16e, and the light emitting element 16a is turned on. Since it is input to the light receiving element 16b is weak output signal in the scattered light, and Zohaba in Zohaba portion 16c, an analog signal by the comparator unit 16f is converted to a digital signal storage stored as temporary data in the storage unit 17 Is done.

When the door 10a is opened by holding the handle, luggage B is stored therein, and when the door 10a is closed, a command is issued from the control unit 13 to turn on the output unit 16e and the comparison unit 16f. The light emitting element 16a is turned on by the output unit 16e, and the reflected and scattered light with the load B is input to the light receiving element 16b. This input is amplified by the amplifier 16c, the analog signal is converted into a digital signal by the comparator 16f, and the input signal is compared with the data in the memory 17 to detect the movement of the package B. At this time, new data is left as temporary data in the storage unit 17 and old data is deleted. Thereafter, when the resident takes out the baggage B from the locker 10, the presence / absence of the baggage is determined by comparing with the previous data in the same procedure.

[0013] In the state without luggage and the state with luggage,
In the former case, since light is absorbed, the reflected input light to the light receiving element 16b is small, and it can be said that the input light becomes relatively large when the baggage B enters. In any case, the light receiving element 16
The reflected light input to b is weak, and cannot be compared and compared unless it is increased at the amplification portion 16c.

In the above description, the locker device for parcel delivery luggage has been described.
If the luggage sensor according to the present invention is used, it is possible to know the presence or absence of mail in a large-scale house or an office building with many tenants by a control panel installed in a convenient place.

The change in the internal state is grasped by the baggage sensor, and the movement of the baggage as well as the presence / absence of the baggage is detected. As a result, the baggage moves even though the unlock signal is not output. In such a case, it is possible to detect the removal of the luggage by prying the hinge and to detect the movement of the luggage inside by rocking the locker device, so that it is easy to level the alarm buzzer.

[0016]

Conventionally, a certain state from a state where there is no luggage is previously recognized by a luggage sensor, and the light must always be emitted. However, in the present invention, since the previous data is stored, the power supply is not used. In the case of batteries, consumption can be prevented. In addition, when the conventional optical sensor was used as a luggage sensor, the luggage sensor failed or malfunctioned due to a voltage drop for some reason or a decrease in the amount of light due to dirt due to long-term use. In the baggage sensor according to the present invention, the reflected light in a state where there is no baggage in the box is captured by the light receiving element and input to the storage unit for comparison, and almost completely prevented.
