And functions as control means for controlling transmission and reception of information to and from the card-shaped storage medium 1.

FIG. 3 is a perspective view showing a state where the card-shaped storage medium is inserted into the medium mounting section, and FIG. 4 is a sectional view showing a state where the card-shaped storage medium is mounted on the medium mounting section. The operation of the above-described configuration will be described with reference to FIG. First, when the card-shaped storage medium 1 is mounted on the apparatus main body 3, the door 5 is opened as shown in FIG. 1 and the card-shaped storage medium 1 is provided in the medium mounting section 4 as shown in FIG. The contact 2 is inserted and placed so as to overlap the connector 10 of the medium mounting section 4 in accordance with the guide rib 9.

Thereafter, when the door 5 is closed, the locking claw 7 is locked to the claw receiving portion 12 of the medium mounting portion 4 as shown in FIG. 4, and at the same time, the rib 8 provided inside the door 5 is The shape storage medium 1 is pressed down. Thereby, the card-shaped storage medium 1
The contact 2 is pressed against the connector 10 of the medium mounting section 4 to make a reliable electrical connection, and at the same time, the card detecting medium 11 pushes the medium detecting means 11, and the medium detecting means 11 1 is detected.

The medium detection signal from the medium detecting means 11 is sent to the control section 18, whereby the control section 11 recognizes that the card-shaped storage medium 1 is mounted on the medium mounting section 4. Thereafter, when the operator inserts a key (not shown) into the lock 13 and turns it, the lever 14 is rotated integrally with the lock 13 and the door 5 is rotated.
At one end of the long hole 16 provided in the first hole, and stops at the other end of the long hole 16.

At this time, since the lock detecting means 17 is pushed by the lever 14, a lock detecting signal is sent from the lock detecting means 17 to the control unit 18. When the control unit 18 receives the medium detection signal from the medium detection unit 11 and the lock detection unit 17 receives the lock detection signal as described above, the control unit 18 makes the electrical connection between the contact 2 and the connector 10 effective, and 1 to exchange information.

As for the transmission and reception of the information, the information input from the input means 19 and the information sent from the external device are stored in the memory 20 so that the electrical connection between the contact 2 and the connector 10 is made effective. After that, the information stored in the memory 20 is transferred to the card-shaped storage medium 1 via the connector 10.
To be stored in the storage medium, or the card-shaped storage medium 1
, And the process of storing the information in the memory 20.

The information stored in the memory 20 is deleted after being transferred to the card-shaped storage medium 1.

In addition, the long hole provided in the door for locking the door with the lever has a width at one end wider than the thickness of the lever. There is no problem in operation, and the width of the other end of the long hole is made equal to the thickness of the lever so that there is no gap between the lever and the long hole in the locked state. Thus, the lock can be reliably detected.

Further, since there is no gap between the lever and the long hole when the door is locked, rattling of the door can be prevented. Therefore, even if the door is intentionally pryed open, there is no clearance. This will help prevent storage media theft.
