[Conventional technology]

Conventionally, purchasing documents such as quotations, order forms, order confirmations, delivery notes, and invoices have been used in various product transactions, but handling a wide variety of documents and large amounts of documents is extremely difficult. It's complicated. From this perspective, in recent years, methods have been developed to streamline form management by filling in forms manually or using a word processor, etc., while automatically reading the forms using an optical character reader (OCR). has been developed, but it has drawbacks in reading accuracy and processing time. In particular, there is a drawback that the larger the number of product items handled, the larger the form becomes. To overcome these drawbacks, it is extremely effective to use an IC card with a built-in CPU and an IC chip such as EEPROM or SRAM.

Therefore, the purpose of this invention is to set up the IC card insertion part in the minimum space for a dedicated input device configured as compactly as possible, and to
To provide an IC card insertion mechanism provided in an IC card dedicated input device that can always achieve proper and smooth insertion and removal operations so as not to damage each other in the relative relationship with electronic circuit components adjacent to a card insertion space.

[Means for solving problems]

The IC card insertion mechanism according to the present invention is an IC card dedicated input device that is equipped with a keyboard, necessary electronic circuits, and a card connector, and configured to removably insert an IC card that exchanges information into the card connector. , an opening for inserting an IC card is provided in a part of the casing of the IC card dedicated input device, and an IC card insertion space is formed on one side of the printed circuit board constituting the electronic circuit; A card connector is connected and arranged so as to be oriented toward the opening of the casing, and IC card guide members are placed on both sides of the casing in close proximity to the opening of the casing. It is characterized in that it is provided integrally with a boss portion that is provided to protrude into the casing.

In the above-mentioned IC card insertion mechanism, the pair of opposing IC card guide members are configured such that their inner surfaces are spaced apart by approximately the same width as the IC card and expand in a curved shape toward the opening.

[Effect]

According to the IC card insertion mechanism according to the present invention,
When an IC card is removably inserted into the card connector provided on the dedicated input device, the inner surface of the casing that forms the insertion space for the IC card is
By providing a pair of guide members spaced apart by approximately the same width as the width of the IC card, and by providing this guide member integrally with a screw attachment boss provided for attaching a board to the casing, for example, this guide member can be It acts effectively as a guide for inserting an IC card, and also has a reinforcing effect when fixing a printed circuit board.

〔Example〕

Next, an embodiment of the IC card insertion mechanism according to the present invention will be described in detail below with reference to the accompanying drawings.

1 to 3 show the main structure of an IC card dedicated input device equipped with an IC card insertion mechanism according to the present invention, in which FIG. 1 is a partially cutaway perspective view, and FIG.
The figure shows a cutaway plan view, and FIG. 3 shows a side view. In FIG. 1, reference numerals 10 and 12 indicate interfitting casing halves, respectively. Also, 14 is an IC card, 16 is a card connector,
18 is a printed circuit board, and 20 and 22 are IC card guide members, respectively. In this embodiment, an opening 24 is provided at one end of the one casing half 10, and an opening/closing lid (not shown) is detachably attached thereto, so that the IC card 14 can be inserted and removed. do. In this case, inside the casing
An insertion space for the IC card 14 is constructed on the printed circuit side of the printed circuit board 18, and a card connector 16 is fixedly arranged on one side thereof. Therefore, I.C.
Electronic circuit components necessary for the card-specific input device are mounted on the back side of the printed circuit board 18 in the illustrated example. Thereby, the IC card 14 can be inserted into the card connector 16 parallel to the front side of the printed circuit board 18 shown.

However, in the present invention, the IC card 14
Opening 24 of the casing half 10 on the side into which the
A pair of IC card guide members 20 having a separation distance W′ that is approximately the same as the width W of the IC card 14 are provided on the inner surface of the side end portion.
22 are integrally provided. The IC card guide members 20 and 22 include boss portions 26 for screwing both sides of the printed circuit board 18 on the inside of the casing half 10, and guide pieces 28 for sliding both sides of the IC card 14 in parallel. These are integrally constituted. In this case, if the opposed guide pieces 28, 28 are configured to expand toward the opening 24 side of the casing, the IC card 14 can be easily inserted. In addition, the boss portion 26
A screw hole 30 is bored in the center of the screw hole 30.
The printed circuit board 18 can be fixed by attaching screws 32 to the screws 32 (see FIG. 1).

In this way, the guide members 20, 22 are attached to the casing on the insertion side of the IC card 14 of the IC card dedicated input device.
By providing this, when inserting the IC card 14 from the opening 24 of the casing, if the IC card 14 is inserted between the guide members 20 and 22,
It is guided straight inside the casing,
The IC card 14 can be properly and smoothly connected and fixed to the card connector 16.
