As shown in FIG. 7, the contact IC sensor 41 is an IC chip that contacts the contact IC card C1 and obtains electronic information from the IC chip. The contact IC card insertion groove 42 is provided in the housing 2 in order to induce the IC chip of the contact IC card C1 to the position of the contact IC sensor 41.

The contact IC card insertion groove 42 is a recessed groove that is opened in the right vertical side surface 26 of the housing 2. The arrangement of the contact IC sensor 41 and the placement and depth of the contact IC card insertion groove 42 are set such that when the contact IC card C1 is inserted into the contact IC card insertion groove 42 at the stop position, the contact type The IC chip of the IC card C1 is stationary at a predetermined contact position of the contact IC sensor 41.

The antenna 51 is provided on the side of the surface 521 of the antenna substrate 52.

The magnetic shielding member 53 is arranged on the side of the antenna substrate 52 that shields the magnetic field lines. Since the magnetic shielding member 53 is disposed on the side of the back surface 522 in the antenna substrate 52, the magnetic lines of force generated by the antenna 51 are absorbed by the magnetic shielding member 53. As a result, the magnetic field MF is hardly formed on the side of the back surface 522 in the antenna substrate 52, and is formed on the side of the surface 521 in the antenna substrate 52 as a center.

The non-contact IC card C2 includes an IC chip and an antenna. As shown in FIG. 8, the antenna 51 of the non-contact IC reading section 5 and the antenna of the non-contact IC card C2 are close to each other and data is transmitted and received therebetween. The non-contact IC reading section 5 is non-contact The IC chip of the IC card C2 obtains electronic information. An example of the non-contact IC card C2 is a card of the Near Field Communication (NFC) standard, which is a type of RFID (Radio Frequency Identifier).

As shown in FIG. 2 and FIG. 4, the non-contact IC reading section 5 is adjacent to the right vertical side surface 26 of the casing 2 and is slightly lower than the central portion in the vertical direction. As far as the thickness direction of the casing 2 is concerned, Arranged on the side close to the front 21. Therefore, the electronic information of the IC chip of the non-contact IC card C2 is obtained by the antenna 51 by bringing the non-contact IC card C2 close to the non-contact IC reading section 5 on the front surface 21 of the housing 2.

That is, the non-contact type IC reading section 5 arranged near the front surface 21 in the thickness direction of the housing 2 is in contact with the side near the back surface 22 in the thickness direction of the housing 2. The type IC reading section 4 is arranged so that most (for example, 70% or more) of the frame 2 overlap each other in the front view.

As shown in FIG. 2, the magnetic reading section 6 is arranged adjacent to the right vertical side surface 26 of the housing 2 in the same manner as the contact IC reading section 4 and the non-contact IC reading section 5. However, the area where the contact IC reading section 4 and the non-contact IC reading section 5 are overlapped with each other in the front view of the housing 2 does not have ample space for placement, so the magnetic reading section 6 is arranged in a comparison This is an upper area that is higher in height than the upper area and the lower area.

The magnetic card insertion groove 62 has a corner portion 27 that intersects the right vertical side surface 26 and the upper horizontal side surface 23 of the frame body 2 from a predetermined second position P2 on the upper horizontal side surface 23 to a predetermined one on the right vertical side surface 26. The first position P1 has a bottom surface 621 extending linearly, and the right vertical side surface 26 is in close proximity to the contact IC reading section 4 and the non-contact IC reading section 5. That is, the magnetic card insertion groove 62 is a substantially triangular groove having the bottom surface 621 as a hypotenuse, and the remaining two sides are open at the upper lateral side 23 and the right longitudinal side 26.

As shown in FIGS. 3 and 4, in the thickness direction of the frame body 2, the magnetic card insertion groove 62 is disposed on a side close to the front surface 21 of the frame body 2. Therefore, the first position P1 on the right vertical side surface 26 of the bottom surface 621 of the magnetic card insertion groove 62 is a position close to the non-contact IC reading section 5 and not a position close to the contact IC reading section 4.

Next, the functions of the portable electronic device 1 configured as described above will be described in order.

As shown in FIG. 7, when the contact IC card C1 is held in the hand and inserted into the stop position of the contact IC card insertion groove 42 of the contact IC reading section 4, the IC chip of the contact IC card C1 is stationary. To a predetermined contact position of the contact-type IC sensor 41. Therefore, the contact IC sensor 41 obtains electronic information from the IC chip of the contact IC card C1. Thereby, the portable electronic device 1 performs the checkout function of the contact IC card C1.

Thereby, the portable electronic device 1 performs the checkout function of the non-contact IC card C2.

As shown in FIG. 9, when the magnetic card C3 is held in the hand and is inserted from the upper lateral side 23 side to the magnetic card insertion slot 62 of the magnetic reading section 6 so as to pass along the bottom surface 621 to the right longitudinal side 26 side, The tester 61 acquires magnetic information from the magnetic recording section C31 of the magnetic card C3. Thereby, the portable electronic device 1 performs the checkout function of the magnetic card C3.

[Position relationship between display section structure 31 and non-contact IC reading section 5]

The positional relationship between the display section structure 31 and the non-contact IC reading section 5 will be described in detail. As shown in FIGS. 10A to 11, the display unit structure 31 It is adjacent to the antenna substrate 52 in a predetermined adjacency direction D5. In the present embodiment, the adjacent direction D5 is the left-right direction of the housing 2 (the direction connecting the left vertical side surface 25 and the right vertical side surface 26).

The position P57 at the outer end edge 537 of the magnetic shield member 53 on the side (left side) of the display portion structure 31 in the adjoining direction D5 is a display portion structure located in a cross section of the antenna 51 made of a loop antenna The position P51 of the outer end edge of the 31 side (left side) is also close to the side (left side) of the display unit structure 31. In this embodiment, the position P55 of the outer end edge 525 of the display unit structure 31 side (left side) in the antenna substrate 52 and the display unit structure 31 side (left side) in the magnetic shielding member 53 are in the adjacent direction D5. The position P57 of the outer end edge 537 is the same.

The symbol P52 indicates the position of the inner end edge on the side of the display unit structure 31 in the cross section of the antenna 51 composed of a loop antenna.

On the other hand, in the adjoining direction D5, the magnetic shielding member 53 is arranged to be more concentrated than the antenna 51 on the side (left side) of the display unit structure 31. Specifically, the position P58 of the outer end edge 538 on the opposite side (right side) of the display section structure 31 in the magnetic shielding member 53 in the abutting direction D5 is located in the cross section of the antenna 51 made of a loop antenna. The position P54 of the outer end edge of the display unit structure 31 on the opposite side (right side) is also closer to the side (left side) of the display unit structure 31.

In the present embodiment, the position of the outer end edge 538 on the opposite side (right side) of the display portion structure 31 in the magnetic shield member 53 in the adjoining direction D5. The position P58 is located closer to the side (left side) of the display unit structure 31 than the position P53 of the inner end edge of the display unit structure 31 on the opposite side in the cross section of the antenna 51 constituted by a loop antenna.

Since the magnetic shielding member 53 is present in a concentrated manner, a region on the opposite side (right side) of the display section structure 31 in the back surface 522 of the antenna substrate 52 is exposed.

[Effect of the embodiment]

According to the portable electronic device 1 of the embodiment, for example, the following effects can be obtained.

As described above, in the prior art, as shown in FIG. 15, the antenna substrate 152 is disposed near the ground with the display unit structure 131 for achieving a display function, and the magnetic properties of the magnetic shielding member are entirely disposed on the other side of the antenna substrate 152 In the sheet 153, the magnetic field lines generated by the antenna 151 form a magnetic field MF on only one side of the antenna substrate 152. At that time, the magnetic field lines were pulled to the side of the display portion structure 131 due to the influence of the metal portion in the display portion structure 131, and as a result, the magnetic field MF was deformed. For this reason, the maximum positional deviation of the magnetic flux of the magnetic field MF is caused, and it is difficult to achieve a desired reading performance using a non-contact IC card.

On the other hand, in the embodiment, the non-contact IC reading section 5 includes an antenna 51 that generates magnetic field lines, an antenna substrate 52 on which the antenna 51 is mounted, and a magnetic shielding member that is disposed on a side to shield the magnetic field lines in the antenna substrate 52. 53.

Adjacent to D5, in the adjoining direction D5, the magnetic shielding member 53 is arranged to be more concentrated than the antenna 51 on the side of the display unit structure 31.

Therefore, as shown in FIG. 12, the magnetic field lines are pulled to the opposite side (right side) of the display section structure 31. As a result, the influence on the magnetic field MF caused by the display portion structure 31 and the influence on the magnetic field MF caused by the concentrated presence of the magnetic shielding member 53 are canceled, and the entire magnetic field MF is easily made symmetrical. That is, the shape MF of the magnetic field of the antenna 51 of the non-contact IC reading section 5 can be corrected due to the influence of the display section structure 31. Therefore, it is easy to make the maximum spot of the magnetic flux of the magnetic field MF coincide with the designed spot, and the desired reading performance using the non-contact IC card C2 will be easily achieved.

The portable electronic device 1 according to the embodiment further includes a contact-type IC reading unit 4 which is configured integrally with the housing 2 and performs reading processing of the contact-type IC card C1. The contact IC reading section 4 and the non-contact IC reading section 5 overlap each other in at least a part of the front view of the housing 2. With such a configuration, the arrangement area of the front view of the contact IC reading unit 4 and the non-contact IC reading unit 5 can be significantly compacted, and the portable electronic device 1 can be made more compact.

On the other hand, the magnetic field MF is not formed on the side of the back surface 522 in the antenna substrate 52, that is, the side of the contact IC reading section 4, and the magnetic field MF is difficult to affect the contact IC reading section 4. Shielding member 53. In this way, even if the magnetic shielding member 53 is provided, as described above, The shape MF of the magnetic field of the antenna 51 of the non-contact IC reading unit 5 can still be corrected, and the shape of the magnetic field MF can be easily deformed due to the influence of the display unit structure 31.
