Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a read/write device for a plate-shaped storage medium incorporating a semiconductor storage circuit.

(Prior art) With recent advances in semiconductor technology, magnetic cards have been replaced as external storage devices for portable computers, etc. by storage devices such as the one shown in Figure 5A, that is, electrically rewritable non-volatile memory EEPROM. , a storage medium called an IC card, which has a CPU that controls these operations molded onto a card-like substrate and has contacts on its surface for connection with external devices.
A RAM card, as shown in Figure B, began to be used, in which a RAM and a backup battery for storing its memory contents were housed in a plate-like case, and contacts were provided on a step formed on the surface. Ta.

In order to read and write these plate-shaped storage media, a device as shown in FIG. Using a reading/writing device in which a contact block E having a contact pin D that contacts the contact point of the plate-shaped storage medium is installed on the stand A, the plate-shaped storage medium is set in the pocket member C and the top plate B is opened. This is done by electrically connecting the contacts of the plate-shaped storage medium and the contact pins D by closing the base A.

However, when the pocket member C is rotated downward, the plate-shaped storage medium swings and deviates from the set position toward the front, and the contact pin D does not properly contact the contact point of the plate-shaped storage medium. There was a problem that there was a risk of poor contact.

(Purpose) In view of these circumstances, the present invention provides a plate-shaped memory that can always form a good contact state by pushing the container back to a specified position using a position regulating member just before locking the container to the base. The purpose is to provide a device for reading and writing media.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

FIG. 1 is a cross-sectional view of an apparatus showing an embodiment of the present invention, in which reference numeral 1 denotes a plate-shaped storage medium container, one side of which is rotatably mounted on a base 2 with a hinge. Approximately 30 degrees due to the biasing force of spring 3 when opened.
The pocket member 5 is comprised of a top plate 4 that stops at an angle of , and a pocket member 5 on the back side of which has a width and a depth that correspond to the length and width of the plate-shaped storage medium, respectively. This pocket member 5 is provided with leaf springs 6, 6, which are bent upward so that their tips come into elastic contact with the front plate 4, extending from the front side to the back side, on the top surface of the pocket member 5, and the plate springs 6, 6 are provided on the top surface of the pocket member 5 so as to extend from the front side to the back side. It is constructed by attaching a member with a window 7 formed at a position corresponding to the contact point to the top plate 4 via a spacer. A receiving member 8 for a plate-shaped storage medium that also serves as a spacer is provided on the back side of the pocket member 5. As shown in FIG. 2, the base 2 is a contact block holder consisting of a frame body with a U-shaped cross section and an open back side facing the contact point of the plate-shaped storage medium loaded in the pocket member 5. A contact block 11 in which a member 9 is provided and contact pins 10, 10, . , 10... are provided so as to be swingable in the direction of rotation of the container 1. Reference numerals 12 and 12 indicate position regulating members which are a characteristic part of the present invention and are provided at two places on the base 2, and as shown in FIG.
3 is cut out on three sides, leaving the back side, to form cantilever beams 14, and at the tips of these, protruding pieces 15 are formed, with a downwardly inclined sloped part 15a on the back side and a flat part 15b on the front side. As shown in FIG. B), when the plate-shaped storage medium is loaded into the pocket member 5 almost normally, the end of the plate-shaped storage medium on the hand side contacts the inclined portion 15a. 16 is a beam member 14
This is a groove provided on the fixed side to provide elasticity. A recess 17 (FIG. 1) is provided on the back surface of the top plate 4 facing the position regulating members 12, 12, so that the container 1 can be moved downward to the extent that the lock can be released when the container 1 is expanded. It is configured as follows.

Reference numerals 18 and 19 indicate a lock pin and a heart lever, which are locking members that can be engaged and disengaged by pressing the container 1 from above, respectively, and 20 indicates that the container 1 is properly locked to the base 2. Each shows a limit switch that detects whether or not the

In this embodiment, when the container 1 is expanded and the tip of the plate-shaped storage medium is pushed into the pocket member 5,
The plate-shaped storage medium E slides on the upper surface of the plate spring 6 while being pressed by the top plate 4 and moves to the receiving member 8. As a result, the plate-shaped storage medium is set in a predetermined position while being pressed against the top plate 4, regardless of its thickness. As a result, even if the plate-shaped storage medium is warped or bent, the deformation can be corrected by the elastic force of the plate spring 6. In this state, when the container 1 is pushed down against the force of the spring 3, the contact pins 10, 10, . . . are pressed downward while coming into contact with the contacts of the plate-shaped storage medium. At this time, if the plate-shaped storage medium moves to the front side and is slightly shifted, the front side of the plate-shaped storage medium will come into contact with the slope 15a of the position regulating members 12, 12, and if the container is further pushed down in this state, the plate-shaped storage medium will shift slightly. The front side of the storage medium is pushed inward along the inclined portion 15a (the fourth
Figure A). In this way, when it comes into contact with the receiving member 8 and is pushed down to a predetermined position, the board storage medium is housed between the receiving member 8 and the wall portion 15c of the position regulating member 12 (see Fig. 4). (b) pin 1 of container 1
8 engages with the heart lever 19, and the container 1 is moved to the base 2.
is locked, and at the same time limit switch 20 is
It turns ON and loading is complete. When the limit switch 20 is turned on and a reading or writing command is input from a keyboard (not shown), a signal is output to the plate-shaped storage medium via the contact pin 10, and the reading or writing is performed. When writing and reading are completed, container 1
When pressed, the container 1 is pushed down to a position where the position regulating member 12 contacts the recess 17 and the pin 18
is removed from the heart lever 19, the lock is released, and the opening is expanded by the biasing force of the spring 3. In this state, container 1
Insert your finger from the front and remove the plate-shaped storage medium from your pocket. Note that when the plate-shaped storage medium is not inserted sufficiently at the initial stage, the back surface of the plate-shaped storage medium comes into contact with the flat part 15b of the position regulating member 12, and the rotation of the container 1 is prevented (see FIG. 4). c) In this case, when the plate-shaped storage medium is pushed inward with a finger and the container 1 is pressed down, it is locked to the base 2 and reading and writing are possible.

In this embodiment, the position regulating members are arranged at two locations, but the same effect can be obtained even if the position regulating members are arranged at one location or three or more locations.

(Effects) As described above, according to the present invention, when the plate-shaped storage medium is normally loaded into the storage body, the upper end is located near the base where the front end of the storage medium is located, and the upper end is on the rear side. Since the downwardly inclined position regulating member is provided, the displacement of the plate-shaped storage medium within the storage member can be automatically corrected when the storage body is locked. Since the leaf spring that presses against the housing member surface is opened at the front side and extended to the back side, the plate-shaped storage medium is guided while sliding from the front side to the back side, and the plate-shaped storage medium is prevented from warping or bending. It is possible to store the storage medium in a modified state and set it in pressure contact with the storage medium regardless of its thickness, thereby realizing reliable contact with the plate-shaped storage medium that is easily deformed when the two come together. can.
