Claims (7)

1. 1. A portable luggage inspection device is provided with: a conveying unit that conveys baggage; an inspection unit that inspects the baggage conveyed by the conveying unit; a curtain shielding electromagnetic waves emitted from the inspection unit for inspection, and An anti-blocking unit that prevents blocking of baggage conveyed by the conveying unit, Wherein, the The anti-clogging unit has: A displacement section having an entrance of a shape corresponding to a range that can be inspected by the inspection unit and movably provided on an entrance side of the inspection unit, the displacement section hitting the baggage so that the baggage cannot enter the inspection unit located in front of the baggage when the conveyed baggage exceeds a size that can be inspected by the inspection unit and being displaced by a force acting when the baggage is in contact with the displacement section, and And a sensor for detecting displacement of the displacement portion when the conveyed baggage hits the displacement portion and displaces the displacement portion.
2. 2. The carry-on luggage inspection device of claim 1, wherein, The displacement section is displaced in a case where the size of the transported baggage exceeds the size that can be inspected by the inspection unit.
3. 3. The carry-on luggage inspection device of claim 1, wherein, The sensor has a magnet portion attached to and detached from the displacement portion in accordance with displacement of the displacement portion.
4. 4. The carry-on luggage inspection device of claim 1, wherein, The sensor is a photosensor that detects displacement of the displacement portion.
5. 5. The carry-on luggage inspection device of claim 1, wherein, The displacement portion has an entrance of a shape corresponding to a range that the inspection unit can inspect.
6. 6. The carry-on luggage inspection device of claim 1, wherein, The luggage inspection device is provided with a forced stopping means which stops the conveying by the conveying means and the inspection by the inspection means when the sensor detects the displacement of the displacement portion.

Description

Portable luggage checking device The application is a divisional application of an application patent application with the application number 202180014476.9, the application date 2021, the year 01 and the month 05 and the name of a hand luggage checking device. Technical Field The present invention relates to a portable baggage inspection device for inspecting baggage while conveying the baggage. Background As a technique for checking baggage, for example, an X-ray foreign matter detection device is known in which a flexible slide sheet is provided on a shielding curtain to prevent X-ray leakage, thereby suppressing hooking of an object to be checked (patent document 1). Prior art literature Patent literature Patent document 1 Japanese patent laid-open publication No. 2002-228601 Disclosure of Invention Problems to be solved by the invention Even if the X-ray foreign matter detection device disclosed in patent document 1 has a structure in which a slide sheet is provided to the shielding curtain, the shielding curtain provided at the entrance of the inspection device may be clogged depending on the weight, shape, or the like of the inspection object, and the throughput of the inspection may be lowered. In particular, when a variety of carry-on baggage such as a shape, a size, a weight, and the like is an inspection object, the problem may become remarkable. The present invention has been made in view of the above, and an object of the present invention is to provide a portable baggage inspection device capable of maintaining and improving the throughput of inspection in the inspection of baggage in, for example, a venue, a railway, and other large-scale transportation facilities. Means for solving the problems In a first aspect, the present invention provides a portable baggage inspection apparatus including a conveyor unit that conveys baggage, an inspection unit that inspects the baggage conveyed by the conveyor unit, a curtain that shields electromagnetic waves emitted from the inspection unit for inspection, and an anti-blocking unit that prevents the baggage conveyed by the conveyor unit from being blocked, wherein the anti-blocking unit includes a displacement portion that has an entrance of a shape corresponding to a range that can be inspected by the inspection unit and is movably provided on an entrance side of the inspection unit, and when the conveyed baggage exceeds a size that can be inspected by the inspection unit, the baggage is hit against the baggage so that the baggage cannot enter the inspection unit located in front of the baggage, and is displaced by a force acting when the conveyed baggage is in contact with the baggage, and a sensor that detects the displacement when the conveyed baggage hits against the displacement portion so that the displacement portion is displaced. According to the portable luggage inspection device of claim 1, when the transported luggage hits the displacement portion, the displacement portion is displaced, and therefore, whether the luggage can be inspected or not can be rapidly detected by a simple structure, and improvement in throughput and saving of manpower of luggage inspection can be achieved. As the 2 nd aspect, in the portable luggage inspection device according to the 1 st aspect, the displacement unit may be configured to displace when the size of the transported luggage exceeds the size that can be inspected by the inspection unit. According to the portable luggage inspection device of claim 2, the size of the luggage transported by the displacement detection of the displacement portion exceeds the size that can be inspected, thereby enabling detection of whether the size is the size through which the portable luggage can pass. As the 3 rd aspect, in the portable luggage inspection device according to the 1 st aspect, the sensor may have a magnet portion attached to and detached from the sensor portion in accordance with the displacement of the displacement portion. According to the portable luggage inspection device of claim 3, the displacement of the displacement portion can be detected by attaching and detaching the magnet portion. As the 4 th aspect, in the portable luggage inspection device according to the 1 st aspect, the sensor may be a photosensor that detects displacement of the displacement portion. According to the portable luggage inspection device of claim 4, the light receiving state of the light changes with the displacement of the displacement section, and thus the detection can be performed.
