Description

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

[Conventional technology]

Such portable information processing devices are equipped with a display, an input keyboard, an IC card reader/writer, etc. in a handy type 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 that it is carried and used by a trader called a route man, who carries wholesale products such as bread, ham, and other foodstuffs in a car and goes around retail stores to sell them to retail stores. Information such as the quantity and amount of transactions is entered and stored on the IC card on the spot, and after returning to the office, this information is transferred to and stored on 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 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 located on the surface, making it difficult to operate.

An object of the present invention is to eliminate the disadvantages of the conventional example, and to provide a portable information processing device that is small, convenient to carry, easy to operate, and can read and write IC cards reliably. .

[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 a display device and a keyboard on the back surface.
An IC card reader/writer consisting of an IC card loading section and a lid covering the top of the loading section is provided,
The lid side of the IC card reader/writer has a pin protruding from both sides of one end and a locking claw protruding from the other end, and the loading part side has a long hole on both sides of one end into which the pin is inserted. An elastic member is provided on this end surface to press the lid end, and a holding means for holding the locking claw is provided on the other end, and an IC card end and an An engaging means for engaging is provided, and an end of the loading portion on the side where the holding means is provided.
The gist is that an IC card position regulating means is provided, and a contact head is buried in the bottom of the loading section.

[Effect]

According to the present invention, the front surface of the flat case is provided with items necessary for input operations, such as a display and a keyboard, making it easy to operate, and an IC card reader/writer, which is not directly necessary for input operations, is provided on the back of the case. This makes it possible to reduce the surface area of the case and make it compact, and since IC cards are thin, even if an IC card reader/writer is provided on the back side, the case does not become particularly thick. The lid, which is biased by an elastic member, moves laterally, allowing the lid to be inserted into the loading section.
The IC card is sandwiched between the engaging means and the card position regulating member and placed in the correct position therebetween.

The structure of the IC card reader/writer 6 will be explained in more detail with reference to FIGS. 4 to 7.
In the figure, reference numeral 11 indicates a loading section for an IC card 12 formed in the flat case 1, 13 indicates a lid that covers the upper part of the loading section 11, and a contact pin 15 is provided on the top surface of the bottom of the loading section 11 so as to be freely retractable. A contact head 14 is embedded. 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 pawl 17 is fitted to the other end. A recess 20 was formed.

Further, a leaf spring 21 that extends upward is provided at approximately the center of the bottom of the loading section 11, and the lid 13 is further provided with a leaf spring 21 that extends upward.
As an opening/closing regulating member, a locking portion 2 is provided which protrudes downward at approximately the center position on both sides of the lid 13 and whose tip is bent outward.
An elongated protrusion 22 designated as 2a is provided, and a hole 23, which is inserted into the loading portion 11 and is narrower than the locking portion 22a, is bored therein.

Furthermore, tapered guide portions 24 and 25 for regulating the mounting position of the IC card 12 are attached to the lid 13, respectively.
is provided at the end of the loading section 11, and the guide section 2 is provided at the end of the loading section 11.
A protrusion 27 is provided on the end of the lid 13 opposite to the side where the IC card 12 is provided, protruding downward as an engagement means for engaging with the end of the IC card 12. The plate spring 19 comes into contact with this protrusion 27. Note that in this embodiment, the tapered portion 24 is formed following the locking claw 17, but the invention is not limited to this;
It may be provided at any location on the opening/closing end of No. 3.

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 on the loading part 11 side, and the side part of the other end is inserted into the plate spring 1.
9, it is attached to the upper surface of the loading section 11 and covers it in a state where it is pressed toward the locking claw 17 side.

In addition, 26 in the figure is a finger resting part, and this shape is formed as a notch in the example shown in the figure, but it is not limited to this, and it can be formed on a finely uneven surface, etc., so that the finger can be caught. That's fine.

Next, I will explain how to use and operate the portable information processing device configured as described above, which is carried around to customers.
To load the IC card 12 into the loading section 11, place your finger on the finger hook 26 and push the lid 13 to the right in the figure against the elasticity of the leaf spring 19.
7 is pulled out from the recess 20, and the lid 13 is lifted upward about the pin 16 by the elasticity of the leaf spring 21. At this time, the elongated protrusion 22 is also attached to the hole 2 along with the lid 13.
3, but the locking part 22a is moved upward in the hole 23.
Since the maximum opening angle of the lid 13 is determined, the entire lid 13 does not come off the case 1, and in this state, the contact pin 15 of the contact head 14 protrudes upward.

Once the lid 13 is opened in this way, the IC card 1

In the reverse operation, the locking pawl 17 fits into the recess 20 from the edge of the loading section 11, and the lid 1
3 is closed and locked. At that time, the locking claw 1
7 fits into the recess 20, the lid 13
The protrusion 27 is pushed by the elasticity of 9 and moves laterally to the left,
As a result, the end portion is in contact with the inside of the protrusion 27.
At the same time as the IC card also moves to the left, the upper and lower edges of the IC card 12 are moved to the guide portion 2, respectively.
The loading portion 11 is in contact with the tapered surfaces of 4 and 25.
is pushed in by the lid 13 toward the bottom of the lid 1
3 is closed, the ends of the tapered surfaces of the guide parts 24 and 25 and the end of the IC card 12 come into contact with each other, and the IC
The storage position of the card 12 is regulated to the correct position. Furthermore, when the IC card 12 is stored in the correct position, the IC card 12 moves laterally within the loading section 11, causing the contact pins 15 of the contact head 14 and the terminals of the IC card 12 to rub against each other. Both terminals are automatically cleaned.

In the closed state, the contact pin 15 of the contact head 14 is moved by the closing force of the lid 13 to the IC.
IC card 1 is pushed downward through card 12
contact formed in 2.

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, the keyboard 3 provided on the front side of the flat case 1 is used. When operated, information is stored in the IC card 12 and displayed on the display 2 at the same time. If necessary, print the information using the printer 4, and use the magnetic card owned by the customer to print the IC card 1.
The information stored in the printer 2 can also be retrieved, and the printer 4 uses a dry battery located in the storage compartment 7 on the back side of the flat case 1 as a power source, and other devices such as the display 2 use rechargeable batteries. I did it like that.

In this way, information can be entered on the spot for each customer,
When returning to the office, the user takes out the IC card 12 from the IC card reader/writer 6 by performing the reverse operation to the above, and transfers and stores the information in a large computer installed here.

〔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. Since the case is provided in the main body, the case can be made even more compact, making it easier to carry and improving operability.

Even if an IC card reader/writer is installed on the back side, the IC card is thin, so the case does not become particularly thick, making it easy to use. Further, since the IC card is always placed in the correct position when loaded by the engaging means and the position regulating means, writing to and reading data from the IC card can be performed reliably.
