Further, in this specification, in order to make it easy to understand the claims, the numbers corresponding to the members shown in the embodiments will be referred to as “claims” and “ In the column of “means”. However, the members described in the claims are not limited to the members of the embodiments.

The bag shown in the perspective view of FIG. 1 and the sectional views of FIGS. 2 and 3 includes a personal computer 1, a receiver, and a GPS antenna 12.
Having an internal volume capable of accommodating the GPS antenna 12
Is fixed to a fixed position.

The bag shown in the figure has, in addition to the personal computer 1 and the GPS antenna 12, a pocket 20, which is a storage section for storing a mobile phone, on the side. Furthermore, the bag in this figure is
A caster 2 is provided on the bottom surface 4A so that it can be moved easily even if it is heavy. The casters 2 are attached to the four corners of the bottom surface 4A so that the bag can run independently and vertically. The caster 2 is fixed to the wheel base 5, and
A. Further, the bag preferably has a thickness of 15 cm so that it can stand alone on the casters 2.
Above. The size of the bag is, for example, 15 × 2
The height is set to 0 cm or more so that the robot can be stably moved vertically.

The bag comprises a bag body 4 and a lid 6 for closing the opening on both sides of the bag body 4. The bag body 4 has a bottom surface 4A.
And vertical surfaces 4B on both sides connected to both ends of the bottom surface 4A.
And an upper surface 4C connecting the upper ends of the vertical surfaces 4B. The bag body 4 is formed in a rectangular shape that is long horizontally with a bottom surface 4A, a vertical surface 4B, and a top surface 4C, and has openings on both sides. The bag body 4 and the lid 6 are made of a material that can transmit radio waves.

As shown in FIG. 4, the bag body 4 has a rectangular reinforcing frame 7A on the inner surface, and a hard plate lining 7B and a soft surface material 8 are stretched on the surface of the reinforcing frame 7A. I have. The hard plate lining 7B is a cardboard, thin and hard plastic plate. The hard plate lining may be formed by laminating a plurality of same or different materials.

Further, a bottom surface 4A, a vertical surface 4B, and a top surface 4C
As shown in the sectional views of FIGS. 2 and 3, the inside of the bag body 4 is divided into two compartments 10 on both sides by a partition plate 9 which is a magnetic metal plate 19. The partition plate 9 divides the inside of the bag body 4 into compartments 10 on both sides and is used together with the magnetic metal plate 19. The partition 9 has a depth of one of the compartments 10 substantially equal to the thickness of the personal computer 1 so that the keyboard of the personal computer 1 housed therein can be conveniently operated. Further, the partition plate 9 reinforces the inside of the bag body 4 including the bottom surface 4A, the vertical surface 4B, and the top surface 4C of the bag body 4, and fixes the guide tube 11 to the inside.

As the partition plate 9, a plate material is used in which a flat iron plate or a hard plate made of plastic such as ABS resin is adhered to the surface of the iron plate. Since the partition plate 9 attaches the attachment of the GPS antenna 12 with magnetic attraction, an iron magnetic metal attached to a magnet is used. Furthermore, since the personal computer 1 is mounted on the partition plate 9, a plate material having a strength that does not deform when the personal computer 1 is mounted thereon is used. The GPS antenna 12 is preferably attached to the partition plate 9 on which the personal computer 1 is placed. Open the bag lid 6 and open the GPS
This is because radio waves can be received by the antenna 12. For this reason, a bag that partitions the inside of the bag body 4 with the two partition plates 9
The partition plate 9 on which the personal computer 1 is mounted is a magnetic metal plate 19.
The other partition plate 9 can be a hard plastic plate. However, both partition plates may be magnetic metal plates. Further, the bag body can be partitioned by one partition plate. In a bag having this structure, one partition plate is a magnetic metal plate to which a GPS antenna is attached.

The partition plate 9 has an outer shape substantially equal to the inner shape of the bottom surface 4A, the vertical surface 4B, and the upper surface 4C. It is connected to the inside of the bag body 4 to reinforce it. The partition plate 9 of this shape is a magnetic metal plate as a whole, and the GPS antenna 12 can be attached anywhere. However, although not shown, a magnetic metal plate may be attached to a part of the partition plate, and the GPS antenna may be attached to a specific position of the partition plate.

A state in which the GPS antenna 12 is attached to the magnetic metal plate 19 is shown in a sectional view of FIG. GP shown in this figure
The S antenna 12 has an attachment tool 29 containing a permanent magnet 30 therein.
Through the magnetic metal plate 19. The attachment tool 29
The permanent magnet 30 is built in the magnetic case 31. The magnetic case 31 is adhered to the GPS antenna main body 12A. The magnetic case 31 is manufactured by press-forming an iron plate into a cup shape having an opening for suction. The opening edge of the magnetic case 31 is substantially flush with the surface of the built-in permanent magnet 30 or slightly protrudes from the surface of the permanent magnet 30. Further, the opening edge of the suction opening of the magnetic case 31 is accurately cut into a flat shape.

The attaching tool 29 having this shape is used for the magnetic metal plate 19.
Then, a magnetic circuit closed by the magnetic case 31 and the magnetic metal plate 19 is formed outside the permanent magnet 30. Therefore, the magnetic flux of the permanent magnet 30 passes through the magnetic circuit closed by the magnetic case 31 and the magnetic metal plate 19, and leakage to the outside can be minimized. Further, as shown in FIG. 6, the attaching tool 29 whose magnetic case 31 slightly protrudes from the permanent magnet 30 is attracted to the magnetic metal plate 19,
A gap is created between the permanent magnet 30 and the magnetic metal plate 19.
However, even in this state, a magnetic circuit closed by the magnetic case 31 and the magnetic metal plate 19 is formed outside the permanent magnet 30. Therefore, the outside of the permanent magnet 30 is magnetically shielded by the magnetic case 31 and the magnetic metal plate 19, so that magnetic flux leakage can be minimized.

As shown in the sectional view of FIG. 3, the GPS antenna 12 can be housed in the compartment 10 opposite to the compartment 10 in which the personal computer 1 is housed. In the bag of this figure, the personal computer 1 is placed in the compartment 10 on the left side of the partition 9 in the figure,
A GPS antenna 12 is housed in a compartment 10 on the right side. Further, the GPS antenna 12 is attracted to the magnetic metal plate 19 so as to face upward with the bag standing upright. The luggage compartment 10 on the right side of the partition plate 9 is attached to the luggage so that the GPS antenna 12 can be attracted and fixed upward.
Further, a magnetic metal plate 19 is fixed at right angles to the partition plate 9. The bag having this structure has a feature that the GPS antenna 12 can receive a radio wave when the bag is set up vertically.

The GPS antenna 12 is connected to the personal computer 1 via a receiver. Therefore, GPS antenna 1
2 has a storage section for a receiver in addition to the GPS antenna 12 and the personal computer 1. In the bag shown in FIGS. 2 and 3, for example, the receiver can be stored in the compartment 10 opposite to the compartment 10 in which the personal computer 1 is built. Although not shown, the receiver may be built in a GPS antenna. The receiver amplifies the signal received by the GPS antenna 12 and inputs the amplified signal to the personal computer 1. The personal computer 1 calculates a signal input from the receiver to obtain a position. The personal computer 1 stores a map in a CDROM or a semiconductor memory, displays the map on a monitor, and displays the calculated position on the map.

Further, in the bag shown in FIG. 1, a mobile phone is stored in a pocket 20. The mobile phone is connected to the personal computer 1. The mobile phone transmits information from the personal computer 1 or inputs the received information to the personal computer 1. Further, when the mobile phone is called from an external phone and receives a specific calling signal, the calling signal is input to the personal computer 1. The personal computer 1 to which the calling signal has been input switches the power on and calculates the position by calculating the signal received by the GPS antenna 12. The calculated position signal is transmitted to an external telephone through a mobile telephone. The external telephone is connected to a personal computer 1, which calculates a position signal and displays the position of the bag on a monitor map. When the position of the bag cannot be determined, the position can be displayed on a map by calling from outside.

Further, this bag incorporates an alarm generator (not shown) such as a buzzer and a speaker. The alarm generator generates an alarm under the control of the personal computer 1. When a mobile phone is called from an external phone, the mobile phone inputs a specific calling signal to the personal computer 1. The personal computer 1 to which the call signal has been input turns on the power and issues an alarm with the alarm generator. At the same time, the personal computer 1 calculates a position by calculating a signal received by the GPS antenna 12, and transmits the calculated position signal to an external telephone through a mobile phone. The external telephone connected to the personal computer 1 displays the position of the bag on the map of the monitor from the input position signal.
When the position of the bag cannot be determined, a call is made from outside to display the position on a map, and further, an alarm is issued from an alarm generator of the bag to inform the position of the bag. For this reason, this bag can notify the position of the bag by both the map and the alarm. However, the alarm generator built in the bag can be directly connected to the mobile phone without using a personal computer, and can be configured to generate an alarm by a call signal input from the mobile phone.

As shown in FIGS. 2 and 3, the partition plate 9 fixed to the bag body 4 is located at the center or almost the center of the bag body 4 so that the personal computer 1 can be stored in one compartment 10. And fixed. The two compartments 10 partitioned by the partition plate 9 need not have exactly the same volume, in other words, the same depth. The depth of one of the compartments 10
What is necessary is just to design so that the personal computer 1 can be stored and used conveniently. The compartment 10 in which the personal computer 1 is stored is made substantially equal to the thickness of the personal computer 1. More preferably, the surface of the keyboard is substantially equal to the upper edge of the bag body 4. This is to prevent the upper surface 4C of the bag main body 4 from being obstructed when the keyboard of the personal computer 1 stored in the compartment 10 is hit. When the personal computer is stored in the compartment in a state of being sunk deeply, when operating the keyboard, the upper surface of the bag body becomes obstructive and cannot be conveniently used.

Further, the bag has lids 6 on both sides for separately opening and closing two compartments 10 provided in the bag body 4.
The lid 6 is connected to the bag body 4 so that the lower end can be bent so that the entire surface of the bag body 4 can be opened. It is connected to the opening edge. The lid 6 shown in the figure has a pocket 15 provided on the surface with a chuck 14 provided in the opening. Pockets can also be provided on the inner surface of the lid.

The bag shown in FIGS. 1 and 2 is provided with a handle 3 which can be pulled out to the bag body 4. The handle 3 is formed by connecting a horizontal grip 3A to the upper ends of two vertical rods 3B, and has an overall U-shape. The two vertical rods 3B are mounted so that they can be vertically inserted into and removed from the bag body 4 via the two guide cylinders 11. Guide tube 1
1 is fixed inside two partition plates 9. The guide cylinder 11 has a tubular shape that allows the vertical rod 3B to slide in and out.

The guide tube 11 is fixed to the inner surface of the partition plate 9 fixed to the bag body 4 via a saddle 16. The saddle 16 is fixed to the partition plate 9 via a rivet 17. The guide cylinder 11 has a vertical rod 3B inserted therein.
The upper grip portion 3A is disposed substantially at the center of the upper surface 4C of the bag. The guide cylinder 11 is fixed to one or both partition plates 9.

When the bag 3 is moved by the casters 2, the handle 3 is pulled out from the bag as shown by a chain line in FIG. When the bag is not moved by the casters 2, the handle 3 is pushed into the bag. As shown by the solid line in FIG. 1, in a state where the handle 3 is pushed into the bag body 4, the handle 3 forms a grip gap 18 between the grip portion 3 </ b> A and the upper surface 4 </ b> C of the bag body 4. The bag may be provided with a concave portion on the upper surface, and a gripping gap may be provided between the grip portion and the upper surface of the bag main body in a state where the handle is pressed into the bag main body.

The handle 3 is stopped by a stopper (not shown) at the position where it is pulled out from the bag body 4 and the position where it is lowered. The grip 3 stops the handle 3 at the pull-out position.
There is a time when the user presses A to move the bag with the casters 2 and a time when the user leans against the grip portion 3A and uses the bag like a cane to rest. In such a state of use, the handle 3
Is stopped with a stopper. Toride 3
Is pushed into the bag and stopped by the grip 3A of the handle 3.
It is time to lift your bag and carry it.

The total length of the vertical rod 3B is designed so that the height from the lower end of the caster 2 to the grip portion 3A is about 80 cm when the handle 3 is pulled up most. However, the height from the lower end of the caster to the grip is 60-100
It can be changed in the range of cm. When the height of the grip portion 3A is about 80 cm, the bag can be most easily pushed and moved. A grip 3A connected to the upper end of the vertical rod 3B
Is extended in the longitudinal direction on the upper surface 4C of the bag to form the grip portion 3A. The grip portion 3A pulls out the two vertical rods 3B to the same length and is held horizontally.

Further, the bag shown in FIG.
