[Problems to be solved by the invention]
In view of the above facts, an object of the present invention is to provide a memory card and a recording apparatus that can reduce the insertion resistance that occurs when a memory card is inserted.
[0005]
[Means for Solving the Problems]
The memory card of the present invention described in claim 1 is characterized in that the plurality of connection terminals arranged on the surface of the memory card are arranged so as to be shifted in the insertion direction into the recording apparatus.
[0006]
According to the memory card of the present invention described in claim 1, since the plurality of connection terminals are arranged so as to be displaced along the insertion direction into the recording apparatus, the connector of the recording apparatus contacts with the displacement. Will do. Here, the shifted arrangement refers to an arrangement in which a part or the whole is shifted, and includes, for example, a case where a part of the connection terminal is shifted. In this way, by arranging the plurality of connection terminals so as not to be arranged in a line, the plurality of connectors can be prevented from coming into contact with the connection terminals. For this reason, it becomes possible to make insertion resistance small.
[0007]
According to a second aspect of the present invention, there is provided a recording apparatus comprising a plurality of connectors that contact with a plurality of connection terminals disposed on a surface of the memory card when the memory card is mounted, and connect to a memory of the memory card.

[0008]
According to the recording apparatus of the present invention as set forth in claim 2, the plurality of connectors of the recording apparatus respectively contact the plurality of connection terminals of the memory card when the memory card is mounted, and connect to the memory of the memory card. At this time, since the plurality of connectors are arranged so that the contact portions with the memory card are displaced along the memory card insertion direction, they are brought into contact with the connection terminals before and after. In this way, by disposing a plurality of connectors without shifting them in a line, the connectors are deformed in succession, so that the insertion resistance can be reduced.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of a memory card and a recording apparatus according to the present invention will be described with reference to the drawings.
[0010]
FIG. 1 shows a schematic perspective view of a memory card and a part of a recording apparatus. As shown in FIG. 1, a plurality of rectangular pattern connection terminals 12 which are conductive portions are disposed on a part of the surface of the memory card 10. The connection terminal 12 is arranged on one side perpendicular to the insertion direction of the memory card 10 into the recording device 14 (arrow A direction), and is shifted back and forth along the insertion direction of the recording device 14 (arrow A direction). It has been arranged. FIG. 2 shows a plan view of the memory card 10. As shown in FIG. 2, in this embodiment, the connection terminals 12 are arranged in a zigzag manner so that the connection terminals 12 alternate with each other.
[0011]
The connection terminal 12 is electrically connected to a memory circuit (not shown) inside the memory card 10. Each connection terminal 12 is a terminal for writing to and reading from a different memory.
[0012]
On the other hand, as shown in FIG. 1, in the recording apparatus 14, the main body 14A is made of an insulator such as resin. As shown in FIG. 4, which is a sectional view taken along the line 4-4 in FIG. 1, the recording device 14 is provided with a socket portion 15 for mounting the memory card 10 from one side surface of the main body 14A. The socket portion 15 is provided with a slot for inserting the memory card 10, and the upper surface of the slot is a guide portion 15 </ b> A that forms a guide surface for guiding the memory card 10 into the recording device 14. A plurality of connectors 16 are provided on the back side of the guide portion 15A corresponding to the mounting position of the memory card 10, and each base portion 16B is attached to the recording apparatus main body 14A. In FIG. 1, the base 16B (see FIG. 4) for attaching the connector 16 to the recording device 14 is not shown. These connectors 16 are connected to a substrate (not shown).
[0013]
As shown in FIG. 1, the connector 16 is made of a metal plate having elasticity and is in the form of a leaf spring. The tip bent in a semicircular shape is urged in the vertical direction with respect to the memory card 10. In the process of inserting the memory card 10, the memory card 10 is contacted and pressed. The position of the contact portion 16A of each connector 16 is shifted along the insertion direction (arrow A direction) of the memory card 10, and is alternately arranged in a zigzag pattern.
[0014]
Here, FIG. 3 shows the state before reaching FIG. 4, that is, one process when the memory card 10 is inserted. As shown in FIGS. 3 and 4, the plurality of connectors 16 are not elastically deformed at once by being pushed by the end portion of the memory card 10, but are deformed one after another according to the amount of insertion of the memory card 10. It is like that.
[0015]
Next, the operation of the first embodiment will be described.
[0016]
As shown in FIG. 1, when the memory card 10 is mounted, the plurality of connectors 16 of the recording device 14 come into contact with the plurality of connection terminals 12 of the memory card 10 and connect to the memory (not shown) of the memory card 10. . At this time, the respective connectors 16 are deformed before and after each other, not simultaneously. This is because the plurality of connectors 16 are arranged such that the contact portions 16A with the memory card 10 are shifted back and forth along the insertion direction (arrow A direction) of the memory card 10. As a result, the insertion resistance can be reduced, and as a result, the memory card 10 can be easily mounted.
[0017]
Next, a second embodiment of the memory card and the recording apparatus will be described with reference to FIGS. The second embodiment is the same as the first embodiment in that the contact portions of the connector of the recording apparatus are displaced in the insertion direction and are alternately arranged in a zigzag shape. The shape and arrangement of the connection terminals are different.
[0018]
FIG. 5 is a plan view of the memory card 10 showing the arrangement of the connection terminals 18. As shown in FIG. 5, the plurality of connection terminals 18 have a rectangular pattern, and one side of the rectangular pattern on the insertion tip portion 10 </ b> A side of the memory card 10 is perpendicular to the insertion direction (arrow A direction) of the memory card 10. L are lined up. On the other hand, in the rectangular pattern of the plurality of connection terminals 18, the other side parallel to one side of the rectangular pattern on the insertion tip 10A side is alternately shifted back and forth along the insertion direction (arrow A direction). It is zigzag shaped. Therefore, there are two types of connection terminals 18, long and short.
[0019]
One of the plurality of connecting terminals 18 having a long side of the rectangular pattern along the insertion direction (arrow A direction) is a GND terminal 18A. FIG. 6 shows a contact state between the connector 16 and the connection terminal 18. As described above, the contact portions 16A of the connector 16 are alternately arranged in a zigzag pattern so as to be displaced along the insertion direction (arrow A direction) as shown in FIG. As a result, one of the plurality of connection terminals 18 that contacts the connector 16 first can be the GND terminal 18A. Thus, the reason why the connector 16 is first brought into contact with the GND terminal 18A is to discharge the static electricity at the time of insertion by taking the ground first.
[0020]
In the above-described embodiment, the arrangement of the connection terminals and the arrangement of the contact portions of the connector have been specifically described with reference to an example in which the arrangement is alternately zigzag. As long as it is shifted along the insertion direction, it is not limited to the above embodiment. Needless to say, the arrangement is not limited to the alternating arrangement, but may be an arrangement in which three or more kinds of deviations are provided, such as an arrangement shifted in a stepped manner.
[0021]
In the above embodiment, the case where the connection terminal is a rectangular pattern has been specifically described as an example. However, the present invention is not limited to this. A polygonal pattern etc. may be sufficient and it is not limited to a rectangular pattern.
[0022]
Furthermore, in the second embodiment, in the plurality of connection terminals, the other side parallel to one side of the rectangular pattern on the insertion tip portion side is shifted back and forth along the insertion direction and alternately zigzag. However, it is possible not to shift this one side. In this case, the connection terminal needs to have a size that can contact all of the connectors when the memory card is mounted in the recording apparatus.
[0023]
【The invention's effect】
As described above, according to the memory card and the recording apparatus of the present invention, there is an excellent effect that the insertion resistance generated when the memory card is inserted can be reduced.
