Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a handheld data processing device, and more particularly to a mounting structure for a plate-shaped storage medium.

(Prior art) A type of handheld data processing device
POS terminals are configured to issue slips using printers based on sales data entered by salespeople on-site, while temporarily storing the entered data and outputting it to the POS device as necessary. There is.

RAM packs are normally used to store this data, but because they require battery backup, they are bulky and have been an obstacle to making handheld terminals smaller and thinner.

In order to solve these problems, the present applicant previously proposed a handheld terminal that allows an IC card to be attached to the back of the housing.

This device can be made smaller and thinner, making it more convenient to carry. However, it is difficult to use because the device must be turned over each time an IC card is inserted or removed, and furthermore, it lacks reliability. I had problems such as.

The present invention has been made in view of these problems, and its purpose is to provide a new method that allows the insertion and removal of an IC card from the surface of the housing, and that also improves the reliability of data communication with IC cards, etc. An object of the present invention is to provide a handheld data processing device.

(Example) The details of the present invention will be described below based on illustrated examples.

FIG. 1 shows an embodiment of the present invention, and reference numeral 1 in the figure shows a microcomputer 2 inside.
1 and a secondary battery 23 to form the main body, the printer 2, magnetic card read/write unit 3, and display device 4 are located on the upper half of the surface, and the power switch 5 and charging switch are located on the side. A terminal 6, a POS terminal 7, and a connection terminal 8 for connecting to a host computer are provided. A recess 1a is formed in the lower half of the casing 1 to accommodate a board 10, which will be described later.
On the substrate 1b that partitions this recess 1a, contact pins 9a, 9a, 9a are provided at positions facing the contacts c, c, c... (Fig. 4) of the IC card.
A contact head 9 is provided. Furthermore, the board has a button 12a which is locked by a signal from a board detection switch 11 and a microcomputer 20 and which opens the board 10 when the board 10 is taken out, at a position where the board comes into contact when the board 10 is closed, which will be described later. A body locking mechanism 12 is provided. Reference numeral 10 designates the aforementioned board, whose upper end is rotatably attached to the upper end of the recess 1a of the housing 1 by a hinge 13, and a keyboard 15 consisting of a switch panel is fixed to the surface. Further, on the back side of the board 10, there is an opening 14a on the expansion side, and a window 14b at a position facing the contacts c, c, c... of the IC card K.
An IC card accommodating member 14 is attached.

FIG. 3 shows an embodiment of the control circuit, and the reference numeral 20 in the figure is input permission means, which is activated by a signal from the panel detection switch 11 to control the keyboard 15 and the magnetic card read/write unit. 3 and the contact head 9 can be input to the microcomputer 21. This microcomputer 21 is
It processes the data from the input permission means 20 and outputs the required data to the printer 2 and display 4, and also outputs the data to be stored in the IC card to the contact head 9, and furthermore, the data to be written to and read from the IC card is If so, it is programmed to lock the disc locking mechanism 12.

In this embodiment, when the power switch 5 is turned on with the board 10 closed in the housing 1 (FIG. 2 I), a signal is output from the board detection switch 11 and the input permission means 20 becomes operable. . In this state, input data from the keyboard 15,
When a magnetic card is loaded into the magnetic card read/write unit 3, data is input to the microcomputer 21 via the input permission means 20.
This data is subjected to necessary data processing and printed by the printer 2 or displayed on the display 4.

To insert an IC card to input/output necessary data or new programs, press the open/close button 12a.
When pressed, the board 10 is unlocked and expanded (Fig. 2), making it possible to insert an IC card.
The signal from the board detection switch 11 stops. As a result, the input permission means 20 switches to an inactive state and refuses to accept data from a keyboard or the like.

The IC is inserted into the IC card accommodating member 14 from the opening 14a.
When card K is inserted and the board 10 is closed again,
The IC card K is pressed against the pins 9a, 9a, 9a, .
0 is enabled (Figure 2 I).

In this state, when a command is input from the keyboard 15 to communicate data with the IC card K,
The microcomputer 21 has an input permission means 20
Data communication is carried out with the IC card K through the communication, and during this communication period, the board locking mechanism 12 is locked, making it impossible to open the board 14. As a result, even if the open/close button 12a is pressed by mistake, the board 14 will not open, and the IC card K will maintain the connection with the microcomputer 21 to ensure data communication.

When data communication from IC card K is completed,
The microcomputer 21 releases the locking state of the locking member 12 and makes it possible to take out the IC card. Thereby, by pressing the opening/closing button 12a, the board 10 is expanded and the IC card can be taken out.

In this embodiment, the upper end of the panel is rotatably attached to the casing, but it is clear that the same effect can be achieved even if either the lower end or the side is attached to the casing with a hinge. be.

(Effects) As explained above, in the present invention, a board with a keyboard on the front side and an IC card accommodating section on the back side is mounted on one side and is mounted on a housing housing a microcomputer and an output means. In a data processing device that is movably attached, there is a board detection means for detecting that the board is locked to the housing, and a board that prevents the board from being opened when the IC card is in a read/write state. Since it is equipped with a body locking means and an input permission means that permits data input only when the body detecting means detects that the body is latched to the housing, it is possible to prevent the body from being opened during communication. In addition, it is possible to make data input possible only when it is detected that the board is securely set in the housing, thereby ensuring the reliability of data communication.
