I have.

As the storage medium 100, for example, a memory stick (trade name of Sony Corporation) which is a plate-shaped storage medium is used.
01 and an outer casing 102. At one end of the storage medium 100, connector pieces 103, 103,... Are arranged, and when the storage medium 100 is inserted and mounted in the storage medium mounting section 14, it is provided inside the display device 13. Not shown connector part and connector pieces 103, 1
, And the storage medium 100
And a control processing circuit described later.

An engagement recess 102a is formed on one side edge of the outer casing 102 of the storage medium 100.

The operation of the eject mechanism 16 when the storage medium 100 is inserted into and ejected from the storage medium mounting section 14 will be described below (see FIGS. 3 to 8).

In a state before the storage medium 100 is inserted into the storage medium mounting portion 14, the operation lever 18 is in the neutral position, and the tension coil spring 23 rotates in any direction of the rotation direction, that is, the R1 direction and the R2 direction. (See FIG. 3). At this time, the locked projection 19a of the operation lever 18 is
At a position separated from the lock portion 22a in the R2 direction. In addition, the end surface of the operated portion 21 a of the eject lever 21 is positioned on the same plane as the side surface of the display device 13.

When the storage medium 100 is inserted into the storage medium mounting section 14, the leading end of the storage medium 100 first comes into contact with the engaging projection 20a of the operating lever 18 (see FIG. 4). When the storage medium 100 is inserted into the storage medium mounting section 14, the storage medium 100 presses the engagement projection 20a, and the action lever 18 is rotated in the R1 direction (see FIG. 5). When the operation lever 18 is rotated in the R1 direction, the tension coil spring 23 is extended, and the urging force in the R2 direction is applied to the operation lever 18.

When the operating lever 18 is rotated in the R1 direction, the locked projection 19a moves over the locking portion 22a of the cover 22 and is separated from the locking portion 22a in the R1 direction (FIG. 5). reference). When the to-be-locked projection 19a attempts to climb over the lock portion 22a, the lock portion 22a is elastically deformed.
2a returns elastically and returns to the original state. Further, with the rotation of the action lever 18 in the R1 direction, the eject lever 2
