DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-stage IC card connector provided with a plurality of IC card connectors into which IC cards can be removably inserted.

[0002]

2. Description of the Related Art In OA equipment, for example, a laser printer,
In order to perform the control efficiently, an IC card which can directly access the control unit of the main body from the outside, for example, an IC card having an IC card slot into which a font IC card or an emulation IC card can be inserted freely is increasing. ing. In other words, fonts require Gothic fonts, Mincho fonts, various European fonts, or large fonts, small fonts, and vector fonts of these fonts. Are not efficient, so many are supplied from optional IC cards. Therefore, a plurality of font IC card slots are required to support multi-font. Many emulation functions are also supplied by an IC card, and communication with a different type of personal computer is enabled by replacing the IC card. However, there is also a demand for this function for multi-emulation, and a plurality of emulation IC card slots are required.

As described above, with the advancement of high performance, multifunction, and high added value of devices, there is a tendency that the use of IC cards, whose functions can be easily added from the outside, increases more and more. However, most of the conventional IC card slots are of a single-piece type, and the slots are distributed and installed as the number of IC cards used increases, so that the installation space becomes large or electric wiring becomes complicated. There was a problem.

On the other hand, a multi-stage type as shown in FIG. 5 has been conventionally known as one of the few plural-sheet insertion types. This means that, for example, three I
C card connector 2 integrally and front card insertion slot 3
Are arranged on the same vertical plane in multiple stages, and the housing 1 is installed on a printed circuit board (hereinafter referred to as PCB) 4,
A connector pin 5 for connecting a board from each IC card connector 2 is pulled out from a pin hole 6 provided in the housing 1 and inserted into a pin hole 7 of the PCB 4.

[0005]

However, according to this, there are the following problems. (1) Since the card insertion port 3 of the whole IC card connector 2 are formed aligned in the same vertical plane, will be a plurality of IC cards plugged overlap aligned before and after the operation of insertion and removal of the I C card Sex was bad. (2) Since all the connector pins 5 of all the IC card connectors 2 are pulled out from the pin holes 6 of the housing 1,
When mounting on CB4, connect all connector pins 6 to PC.
It has to be inserted into the pin hole 7 of B4 at a time, and it is difficult to mount the IC card connector 2 on the PCB4.

[0006] It is an object of the present invention, is a good operability of the insertion and removal of the IC card to the IC card connector, I
The object is to make it easy to mount the C card connector on a PCB.

[0007]

The IC card connector has a socket for connecting to the substrate.
A locator 33 for guiding the connector pin 18 is provided .
It is characterized by the following.

[0010]

According to the first aspect of the present invention, a plurality of I
Vertical spacing and front and rear of C card connectors 14a and 14b
Is secured by the spacer unit 28 .

[0011] According to the second aspect of the present invention, an IC card is provided.
The guide card 34 guides the card to the IC card connector 14.
a.14b .

Further, in the invention according to claim 3, a plurality of
Connector for connecting the IC card connectors 14a and 14b to the board
The printed board 1 is guided by the locator pin 18 by the locator 33.
Connect to 7 .

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

FIG. 4 is a schematic configuration diagram of a laser printer having a multi-stage IC card connector according to the present invention. This laser printer is provided with an IC card mounting portion 11 on the front surface of the main body 10, and a plurality of IC cards (not shown) for fonts and emulation are removably inserted into the main body 10 so that the inside of the main body 10 can be inserted and removed. The function of the control unit 12 can be expanded.

FIG. 1 is an exploded view of a part of a multi-stage IC card connector according to a first embodiment of the present invention. You can see from the figure
As described above, according to the present invention, a plurality of IC card connectors 14
a and 14b are separated from each other, and the lower IC card connector 14a and the upper IC card connector 14b are stacked . At this time , a flat U-shaped spacer unit 28 is interposed between them. The spacer unit 28 includes
