The structure is such that it can be pressed against the side to make an electrical connection.

Therefore, the operation of attaching and detaching the memory pack is complicated, and the lid 12
If the connector 6 is removed, the connector 6 will be exposed, and if another conductor or the like comes into contact with this part, the electronic circuit on the main body 1O side will be destroyed.

This had the disadvantage of reducing the ff1 reliability.

[Purpose] The present invention was made to eliminate the following drawbacks of the conventional technology, and it facilitates the attachment and detachment of a memory pack to the electronic device main body side and electrical contact separation, and provides highly reliable memory packs. The purpose is to provide electronic equipment.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 3 and subsequent figures illustrate one embodiment of the present invention, and in each figure, the same or corresponding parts as in FIGS. 1 and 2 are denoted by the same reference numerals, and the explanation thereof will be omitted.

Although not shown in the conventional example, a backup battery 14 is provided in the memory pack 1 in case the memory circuit element in the memory pack is a RAM.

Further, in this embodiment, as shown in FIG. 3, an insertion opening 13 for the memory pack 1 is provided on the side surface of the electronic device main body 10.

The details of the memory pack accommodation mechanism will be explained below.

The storage mechanism for the memory pack of the electronic device according to the present invention is the fifth one.
The structure adopted is as shown in the diagram below.

That is, a main frame 18 is fixed to the main body of the electronic device, and a memory pack support 16 is housed therein so as to be movable up and down, and a connector support frame 20 is attached within this support 16. .

The reference numeral 15 is a release lever.

The main frame 18 is formed as a casing with an open upper end, and has side plates 18a and 18b at the front and rear.

The support body 16 of the memory pack is fitted into the side plates 18a, 18b so as to be movable up and down while being restricted from front to back.

The support body 16 is formed as a substantially quadrilateral frame with its top and bottom open, and has left and right side plates 16b and 16c, and a part thereof has an elongated rectangular memory pack insertion slot 17.

The support body 16 is housed within the main frame 18 in a state where it is suspended by a spring 19 and is movable up and down.

That is, the upper end 19a of the spring 19 is hung in the small hole 18c formed in the upper end of the left and right side plates of the main frame 18, and the lower end 19b is hung in the left and right side plate 16a of the support body 16.
The support body 16 is suspended in the air by a spring 19.

On the other hand, the connector support frame 20 is provided with a connector 6 on its side surface, and one end of a flexible printed circuit board 21 is connected to the connector 6.

This connector support frame 2o is the support body 1 of the memory pack.
The memory pack is housed in a space along the memory pack insertion slot 17 of No. 6.

The connector support frame 20 has two bent portions 20a and 20b arranged vertically on the left and right side edges thereof, and the bent portion 20a located on the upper side is formed in the vertical movement 18c formed on the main frame 18. It is rotatably supported by a screw 22 that is fitted into the shaft.

Further, the bent portion 20b located on the lower side is rotatably supported by a screw 24 fitted in a hook-shaped guide hole 23 formed on the left and right side surfaces of the support body 16.

A spring 25 is stretched between this screw 24 and a new curved portion 18d formed on the side of the main frame 18 and near the side plate 18b.

Therefore, the connector support frame 20 is given the habit of rotating counterclockwise about the screw 22 in FIG. 5 by the spring 25.

On the other hand, the release lever 15 has a bent portion 28a of a frame 28 that opens upward in a U-shape fixed to one end thereof, and this frame 28 is located on the bottom plate 18e of the main frame 18. The bent portion 28a side faces outward from the lower end of the side plate 18b (see (A) and (B) in FIG. 4).

Furthermore, below one side plate of the main frame 18, a bent part 18g is cut and raised at a right angle outward from the lower end of the side plate, and the end of the release lever 15 is inserted from the space below this bent part 18g. is derived, and this part is the third
As shown in the figure, it is exposed on the side of the electronic device main body 10.

Further, the release lever 15 is rotatably supported on the bending portion 18g by a screw 29 in a horizontal plane.

Furthermore, elastic hooks 26 are formed on a portion of the left and right side plates near the upper end of the main frame 18, and these hooks 26 are fitted into grooves 27 formed on the left and right edges of the memory pack 1. will be combined.

Next, the operation of this embodiment configured as above will be explained.

Before inserting the memory pack 1 into the insertion opening 17 of the support 16, or even after inserting the memory pack 1, before the memory pack 1 is completely pushed in, the support 16 is pulled upward by the spring 19, so the screw 24 has a hook shape. It is located at the lower end of the vertical portion of the guide hole 23.

In this state, even if the tensile force of the spring 25 is applied, the screw 24 is located in the vertical part of the guide hole 23, as shown in FIG.
), in the connector support frame 20, the connector 6 is located away from the space 16e below the insertion opening 17, and the connection terminal 8 is located away from the memory pack 1 being inserted.

In this state, the memory pack 1 is inserted into the insertion opening 17 of the support 16, and when its lower end contacts the bottom plate 16f of the support 16, the spring 19 is expanded and the support 16 is lowered.

As a result, the screw 24 comes to be located on the horizontal side of the hook-shaped guide hole 23, and the support frame 20 is pulled toward the memory pack 1 by the length of the horizontal portion by the spring 25.

Therefore, the support frame 20 is displaced from the inclined state shown in FIG. connection is completed.

When the memory pack 1 is attached in this manner, the screw 24 is in the horizontal part of the hook-shaped guide hole 23, so the support body 16 is pulled up by the tensile force of the spring 19 and maintains its position. .

If you want to take out the memory puncture 1, press the release lever 15.
The support frame 20 is attached by the inner end of the U-shaped frame 28.
The spring 24 is moved from the horizontal part of the hook-shaped kite hole 23 to the vertical part by the tensile force of the spring 19. The support body 16 rises, and the connection terminal 8 separates from the memory pack 1, and the electrical connection is broken.

In addition, when the memory pack 1 is completely installed, the hook 26 on the main frame 18 side is at 1+% of the memory pack 1.
Since it is press-fitted into the 'i 27, no displacement will occur unless a large external force is applied.

[Effects] As is clear from the above description, according to the present invention, electrical connection and mechanical retention can be achieved in conjunction with the mounting operation of the memory pack, and ejection can also be performed by operating only the release lever. This greatly simplifies the installation and removal work.

In addition, the connection terminal of the connector is always separated from the memory pack when attaching or removing the memory pack, so the contact part has good durability, and the connector is housed inside the device so that it cannot be touched from the outside. Reliability can be improved.

Furthermore, if the memory pack has a battery, it is possible to replace the battery while the memory pack is electrically connected to the electronic device, and when replacing the battery, power can be supplied to the RAM of the memory pack from the electronic device. It becomes possible to replace the battery of the memory pack without erasing the contents of the RAM.
