Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a small, hand-held portable information processing device.

[Conventional technology]

Such portable information processing devices are equipped with a display, an input keyboard, an IC card reader/writer, etc. in a handy case, and an IC card is loaded and various information is entered using the keyboard. I'm trying to remember it. An example of its use is when a business operator carries and uses a so-called route man who loads wholesale products such as bread, ham, and other foodstuffs into a car, travels to retail stores, and sells them here. Information such as the quantity and amount of the transaction is entered and stored on the IC card on the spot, and after returning to the office, this information is transferred to and stored in a large computer installed separately here.

By the way, conventional portable information processing devices have not only a display and a keyboard but also an IC card reader/writer provided on the surface of the case.

[Problem that the invention seeks to solve]

However, although IC cards are thin, they have a large surface area, so if an IC card reader/writer is installed on the surface of the case, the entire case must be made larger, making it difficult to carry. There is also a risk that the reader/writer will be on the surface, making it difficult to operate.

SUMMARY OF THE INVENTION An object of the present invention is to provide a portable information processing device that is small, convenient to carry, and easy to operate, eliminating the disadvantages of the conventional example.

[Means for solving problems]

In order to achieve the above object, the present invention provides a display device and a keyboard on the front surface of a flat case, and an IC card reader/writer on the back surface.

[Effect]

According to the present invention, the front surface of the flat case is equipped with items necessary for input operations, such as a display and a keyboard, making it easy to operate, and the IC card reader/writer, which is not directly necessary for input operations, is mounted on the back of the case. By providing this, the surface area of the case can be reduced to make it smaller, and the I
Since the C card is thin, even if an IC card reader/writer is provided on the back side, the case does not become particularly thick.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a front view showing an embodiment of the portable information processing device of the present invention, FIG. 2 is a top side view of the same, and FIG. 3 is a back view of the same. A display 2 using a liquid crystal display or other display means is provided approximately in the center of the screen, a keyboard 3 consisting of a numeric keypad or other operation keys is provided below the display 2, and a printer 4 as another display means is provided.
and a magnetic card reader 5.

An IC card reader/writer 6 is provided almost in the center of the back surface of the flat case 1, and a storage part 7 for a dry battery used in a printer 4 which consumes a particularly large amount of electricity is provided.

A connection terminal 8 for connecting to another POS, a connection terminal 9 for connecting to a computer, and a charging terminal 10 for a battery (not shown) built in the flat case 1 are provided on the side of the flat case 1. This rechargeable battery is used as a power source for the display 2, a microcomputer (not shown) built into the flat case 1, and the like.

The structure of the IC card reader/writer 6 will be described in more detail with reference to FIGS.
indicates a lid that covers the upper part of the loading section 11, and a contact head 14 having a contact pin 15 retractably provided on the -L surface is embedded in the bottom of the loading section 11.

As an opening/closing mechanism for the lid 13, a pin 16 is protruded from both sides of one end on the lid 13 side, and a locking pawl 17 is protruded from the other end, and the pin 16 is provided on both sides of the one end on the loading section 11 side. A long hole 18 into which the lid 16 is inserted is provided, and a plate spring 19 that bulges inward in a chevron shape and presses the end surface of the lid 13 is attached to this end surface, and the locking claw 17 is fitted to the other end. Recess 20
was formed.

In addition, a leaf spring 21 is provided at approximately the center of the bottom of the loading section 11 and extends upward, and is further provided with a leaf spring 21 that protrudes downward at approximately the center of both sides of the lid 13 and has its tip bent outward as a member for regulating the opening and closing of the lid 13. An elongated protrusion 22 serving as a locking portion 22a is provided, and the elongated protrusion 22 is inserted into the loading portion 11 and the locking portion 2 is inserted into the loading portion 11.
A hole 23 that is +11 narrower than hole 2a is bored.

Further, tapered guide portions 24 and 25 for regulating the mounting position of the IC card 12 are provided at the ends of the lid 13 and the loading portion 11, respectively. In this embodiment, the tapered portion 24 is formed following the locking pawl 17, but the tapered portion 24 is not limited to this, and may be provided at any location on the opening/closing end of the lid 13.

In this way, the pin 16 of the lid 13 is inserted into the elongated hole 18, the locking pawl 17 at one end fits into the recess of the loading section 11, and the side of the other end is fitted with the leaf spring 19. It is attached to and covers the upper surface of the loading section 11 in a state where it is pressed toward the locking claw 17 side.

In addition, 26 in the figure is a part for the finger to rest on. Although this shape is formed in a notch in the illustrated example, the shape is not limited to this, and it may be formed in a finely uneven surface, etc., so that the finger can be caught. It is fine as long as it is something.

Next, I will explain how to use and operate the portable information processing device configured as described above.The portable information processing device configured as described above is carried around to customers. If you put your fingertip on the finger hook part 26 and push the lid 13 to the right in the figure against the elasticity of the leaf spring 19, the locking pawl 17 will be pulled out from the recess 20, and the lid 13 will be moved against the elasticity of the leaf spring 21. It can be lifted upwards using the pin 16 as an axis. At this time, the elongated protrusion 22 also moves upward in the hole 23 together with the lid 13, but since the locking part 22a is caught on the edge of the hole 23, the maximum opening angle of the lid 13 is determined, and at the same time the lid 13
3 does not come off from the case 1, and in this state, the contact pin 15 of the contact head 14 is -1
It stands out on one side.

Once the lid 13 is opened in this way, insert the IC card 12 between the leaf spring 21 and the lid 13 into the loading section 11, and then move the lid 13 to the right against the elasticity of the leaf spring 19. When pushed downward, the locking pawl 17 fits into the recess 20 from the edge of the loading section 11 in the opposite direction to the opening operation, and the lid 13 is closed and locked. At that time, I
The upper and lower edges of the C card 12 are respectively guided by guide portions 2.
The end of the tapered surface of the guide section 24.25 and the end of the IC card 12 are pushed in toward the bottom of the loading section 11 by the lid 13 while making contact with the tapered surface of the guide section 24.25. Accordingly, the storage position of the IC card 12 is regulated.

In the closed state, the contact pins 15 of the contact head 14 are pushed downward through the IC card 12 by the closing force of the lid 13 and come into contact with contacts formed on the IC card 12.

In order to input transaction information such as transaction quantity and amount at a business partner using the portable information processing device loaded with the IC card 12 in this manner, a keyboard 3 provided on the front side of the flat case 1 is used. If you operate , the information will be transferred to IC card 1.
2 and displayed on the display 2 at the same time. If necessary, print the information using the printer 4, and
IC card 1 using the magnetic card owned by the business partner
The information stored in the printer 2 can also be retrieved, and the power supply for the printer 4 uses a dry battery located in the storage compartment 7 on the back side of the flat case 1, and other devices such as the display 2 use rechargeable batteries. I did it like that.

In this way, you can enter information manually for each business partner on the spot, and when you return to the company, insert the IC card 12 into the IC card by performing the operations in reverse order.
The information is taken out from the card reader/writer 6, transferred to a large computer installed here, and stored.

〔Effect of the invention〕

As described above, the portable information processing device of the present invention has only the keyboard and other items directly necessary for input operations on the front side of the case, and an IC card reader/writer that is not directly necessary for input operations and has a large surface area on the back side. By making the case more compact, it becomes easier to carry, and it also improves operability.

Even if an IC card reader/writer is provided on the back side, since the IC card is thin, the thickness of the case does not particularly increase, and the case is easy to use.
