〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

In the figure, (11) shows a card loading mechanism according to the present invention as a whole, and this card loading mechanism (11) is constructed on a mechanical board (12) arranged in the radio receiver (1) described above. is there.

As shown in FIG. 1, on the front surface side of the mechanical substrate (12), a detection unit (13) for reading the marking (6b) of the card (6) and identifying the type of the card is provided at a predetermined position in the back. Between the detector (13) and the insertion slot (7),
A slide holder (14) is arranged slidably inward and outward. Reference numeral (15) is a guide portion provided on the mechanical substrate (12) for defining the moving direction of the slide holder (14).

Holding pieces (16) for holding the card (6) at the upper and lower edge portions are formed on both upper and lower sides of the slide holder (14), and the leading edge of the card (6) contacts the inner end portion. The card (6) having the locking wall part (17) to be contacted and locked, the half half of one side of the card (6) inserted from the insertion port (7) is held by the slide holder (14), and a predetermined loading position is set. That is, the marking (6b) is transferred to the corresponding position on the detection section (13).

An elastic engaging claw (18) is integrally provided on one side of the slide holder (14) corresponding to the recess (6c) formed on the side edge of the card (6). By engaging the recess (6c) of the card (6) with the engaging claw (18), the card (6) can be held more securely by the slide holder (14).

A mechanism for moving the slide holder (14) is formed on the back side of the mechanical substrate (12) as shown in FIG.

A projecting pillar (19) is integrally provided on the back surface side of the slide holder (14), and the projecting pillar (19) penetrates the elongated hole (20) and faces the back surface side of the mechanical substrate (12). I'm out.

Further, a reversing lever (hereinafter simply referred to as a lever) (21) is located at the lower end of the mechanical substrate (12) corresponding to the projecting pillar (19) of the slide holder (14) to move the slide holder (14). It is rotatably pivoted in the same direction as the direction, that is, inward and outward, and its free end faces the projecting pillar (19) at a predetermined distance. This lever (21) is connected to the base plate (12). Due to the biasing force of the return spring (22) mounted between them, the return spring (22) is urged to rotate so as to always return to the outer rotation end. The spring force of the return spring (22) is set to be stronger than that of the operation spring described later.

The lever (21) is provided on the substrate (12) so as to be slidable inward and outward. The operating member (23) is configured to be rotated, that is, the operating member (23).
One end of is projected as an eject button (10) to the side of the housing of the radio receiver (1), and the other end is engaged and connected to the lever (21). In the normal state, the free end of the lever (21) is located at a position corresponding to the approximate center of the outer moving end and the inner moving end of the protrusion (19) of the slide holder (14), When the button (10) is pushed in fully, the lever (21) is rotated against the biasing force of the return spring (22) until the free end of the lever (21) exceeds the inward moving end of the protrusion (19). Is made.

The slide holder (14) is provided between the free end of the lever (21) and the protrusion (19) of the slide holder (14).
An actuating spring (24) for imparting a moving force is attached to the. That is, in this example, a so-called torsion coil spring is used as the actuating spring (24), and the end of the arm (24a) at one end is protruded with the end of the arm (24a) and (24b) narrowed. The end of the other arm (24b) is rotatably engaged with the center of (19) and the free end of the lever (21), respectively. Between the projecting column (19) and the lever (21), forces are always applied in the directions away from each other.

Next, the card loading mechanism (1
The operation of 1) will be described.

First, when the card is not inserted, the slide holder (14) is biased by the force of the actuating spring (24) to the outer side moving end, that is, the position closest to the insertion port (7), and is in the card standby state. It is kept (see FIGS. 1 and 4).

When the card (6) is inserted from the insertion opening (7) from this state, the card (6) is immediately held by the slide holder (14) (see FIG. 2), and when the card (6) is further inserted, the force is exerted. The slide holder (14) is pushed and moves inward (see FIG. 5). Then, when the projecting pillar (19) of the slide holder (14) exceeds the dead point of the operating spring (24), the direction of the force of the operating spring (24) reverses and the slide holder (14) moves inside. The card (6) is loaded in a predetermined loading position, that is, a position where the marking (6b) faces the detecting portion (13) (see FIGS. 3 and 6). In this state, the actuating spring (24) presses the slide holder (14) inward and the lever (21) outward, and stabilizes in a state.

Thus, in the card loading mechanism (11) of this example,
Insert the card (6) to a certain position to insert the card (6)
Operates so that it is automatically pulled in and reliably loaded in a predetermined loading position.

Further, when the card (6) is taken out from this card loaded state, if the eject button (10) is pressed, the lever (21) interlocks with this and rotates inward against the force of the return spring (22). The other end arm (24b) of the actuating spring (24) is moved.
Move the terminal (see FIG. 7). Then, when the free end of the lever (21) is rotated beyond the dead point of the operating spring (24), the direction of the force of the operating spring (24) is reversed again and the slide holder (14) is moved outward. The card (6) is pushed out of the insertion slot and is ready for removal (see FIG. 8).

As described above, in the card loading mechanism (11) of this example, when the card (6) is inserted to a certain position, the card (6) is automatically pulled in and reliably loaded in the predetermined loading position, and the eject button is pressed. The card (6) can be easily taken out by a one-touch operation of simply pressing the (10), so that the card (6) can be loaded and unloaded with a good operation feeling. Since the card loading mechanism (11) has an extremely simple structure that operates by utilizing the reversal of the force of the actuating spring (24), it can be easily applied to a portable radio receiver.

It is needless to say that the present invention is not limited to the card channel selection type radio receiver shown in this example, but can be widely applied to various electronic devices and other card loading mechanisms.
