Description

  The present invention relates to a portable information processing apparatus capable of wireless communication using electromagnetic waves.

  A tablet-type information processing apparatus in which a display unit is arranged is known. A tablet-type information processing apparatus is generally a portable device that is used by being held by a user's hand. As such a tablet-type information processing apparatus, an apparatus that changes the orientation of an image displayed on a display unit in accordance with a usage pattern of a user has been proposed (for example, see Patent Document 1).

  FIG. 5 is a perspective view showing a configuration of a conventional tablet personal computer 101 (hereinafter referred to as PC 101). The PC 101 includes a main unit 102 that processes information and a monitor device 103. In FIG. 5, the PC 101 is arranged such that the rectangular display unit 104 of the monitor device 103 faces outward. For example, when the user operates the PC 101 with the side surface 105 a of the PC 101 placed on the chest, the PC 101 displays an image on the display unit 104 such that the long side direction of the display unit 104 is the vertical direction of the image. Further, when the user operates the PC 101 with the side surface 105 b of the PC 101 placed on the chest, the PC 101 displays an image on the display unit 104 such that the short side direction of the display unit 104 is the vertical direction. That is, in the PC 101, each side surface may hit the user's chest.

  In addition, in the PC 101, wireless LAN antennas 106a and 106b are arranged in the vicinity of the outer edge of the display unit 104 in order to communicate with the outside. When the user's chest is in contact with the side surfaces 105a and 105b on which the antennas 106a and 106b are disposed, the PC 101 specifies a specific absorption rate (SAR) standard (Ministry of Internal Affairs and Communications ordinance) indicating the degree of electromagnetic wave energy absorbed by the human body. ) May not be satisfied. Therefore, in the PC 101, when the side surface 105a of the PC 101 on which the antenna 106a is disposed is in contact with the chest of the user, the electromagnetic wave is not radiated from the antenna 106a but is radiated from the antenna 106b. When the side surface 105b of the PC 101 on which the antenna 106b is disposed is in contact with the chest of the user, the electromagnetic wave is radiated from the antenna 106a without radiating the electromagnetic wave from the antenna 106b.

For this reason, a certain distance arises between a user's chest and the antenna from which electromagnetic waves are radiated. As a result, the SAR is reduced, and the PC 101 can satisfy the SAR standard.
JP 2007-295393 A

  However, the conventional PC 101 requires two antennas 106a and 106b, which increases the manufacturing cost. Furthermore, since the two antennas 106a and 106b are arranged on different side surfaces of the monitor device 103, wiring is complicated.

  In addition, due to the recent enhancement of functions of information processing devices, battery storage units or various terminals are arranged on the side surface of the main unit 102 and the side surface of the monitor device 103. It is difficult to ensure a sufficient space for arranging the wiring connected to the antenna.

  SUMMARY An advantage of some aspects of the invention is that it provides an information processing apparatus such as a personal computer that can satisfy the SAR standard while maintaining the transmission / reception characteristics of an antenna.

  In order to solve the above problems, an information processing apparatus according to the present invention includes a main unit having an information processing unit for performing information processing, a display unit disposed on one main surface of the main unit, and the information processing unit. An antenna that converts the information signal generated into an electromagnetic wave signal by a communication device unit and transmits the signal to the outside, and a handle that protrudes from one side surface of the main unit and grips the main unit. The main unit is disposed between the display unit and the handle.

  According to the present invention, by providing the antenna between the handle and the main unit, it is possible to provide an information processing apparatus that satisfies the SAR standard because a certain distance is maintained between the human body and the antenna.

  The information processing apparatus of the present invention can take various modes based on the above-described configuration. That is, in the information processing apparatus of the present invention, an attitude detection unit that detects the attitude of the main unit, and an image processing unit that changes the orientation of an image displayed on the display unit according to the attitude detected by the attitude detection unit It can be set as the structure provided with.

  The information processing unit can determine the usage state of the user according to the posture detected by the posture detection unit, and can display the image on the display unit in a portrait or landscape orientation in a direction that is easy for the user to view.

  FIG. 1 is a perspective view showing a configuration of an information processing apparatus 1 according to an embodiment of the present invention. Although not shown, the main unit 2 includes an arithmetic device and a storage device for performing information processing. A display unit 3 is arranged on one main surface of the main unit 2. The display unit 3 is a tablet type display that has a digitizer or touch panel function, and can be operated by touching the display surface with an operation pen, a finger, or a touch pen (not shown). The main unit 2 has four side surfaces: a first side surface 5a, a second side surface 5b, a third side surface 5c, and a fourth side surface 5d. The second side surface 5b and the fourth side surface 5d are substantially orthogonal to the first side surface 5a, and the third side surface 5c is substantially parallel. An operation button 4 is arranged in the vicinity of the display unit 3 on the surface of the main unit 2 on which the display unit 3 is arranged. When the user operates the operation button 4, for example, the information processing apparatus 1 emits light for reading from a bar code reader 11 to be described later, and receives light reflected by the bar code as a read unit. The bar code can be read.

  The first side surface 5a is provided with a handle 6 that extends from both ends and protrudes from the first side surface 5a. The user can easily carry the information processing apparatus 1 by holding the handle 6.

  Further, a WWAN (Wireless Wide Area Network) antenna 7 and a WLAN (Wireless Local Area Network) antenna 8 are disposed in the vicinity of the first side surface 5a. The WWAN antenna 7 and the WLAN antenna 8 can transmit / receive data to / from a server or the like. Also, a Bluetooth (registered trademark) antenna 9 is disposed in the vicinity of the first side surface 5a. The Bluetooth antenna 9 can exchange data with other devices. Further, a GPS (Global Positioning System) antenna 10 is disposed in the vicinity of the first side surface 5a. The position of the information processing apparatus 1 can be accurately known by the GPS antenna 10. The WWAN antenna 7, the WLAN antenna 8, the Bluetooth antenna 9, and the GPS antenna 10 in this embodiment are arranged in consideration of antenna characteristics and space. For example, the arrangement of the Bluetooth antenna 9 and the GPS antenna 10 is information processing. It is not necessary to superimpose in the thickness direction of the apparatus 1 and may be arranged at an independent position.

  The WWAN antenna 7, the WLAN antenna 8, the Bluetooth antenna 9, and the GPS antenna 10 (hereinafter referred to as various antennas 7 to 10) disposed on the first side surface 5a are disposed in the vicinity of the first side surface 5a. Since it is at least about 1 cm away from the second side surface 5b and the fourth side surface 4c, the SAR countermeasure can be satisfied as will be described later.

  In addition, although mentioned later for details, the electromagnetic waves radiated | emitted from various antennas 7-10 are easy to be absorbed by a human body.

  A barcode reader 11 is disposed in the vicinity of the third side surface 5c. Although not illustrated, the second side surface 5b and the fourth side surface 5d are provided with a battery storage unit for storing a battery for driving the information processing apparatus 1, an input / output terminal for inputting data from the outside, and the like.

  FIG. 2 is a plan view showing a state where the front casing and the display unit 3 of the information processing apparatus 1 are removed. A chassis 13 is disposed at the center of the main unit 2. The chassis 13 is made of metal, and the attitude detection unit 15 and the information processing unit 14 are disposed therein. The chassis 13 is preferably formed of a magnesium alloy in consideration of thermal conductivity, robustness, and light weight.

  The posture detection unit 15 includes an acceleration sensor, and detects the posture of the main body unit 2 to determine in what direction the user is using the information processing apparatus 1. The information processing unit 14 includes an arithmetic device and a storage device, and also includes an image processing unit that performs image processing for converting the orientation of the image displayed on the display unit 3 based on the detection result of the posture detection unit 15. For example, the information processing unit 14 determines that the second side surface 5b is on the user side when the second side surface 5b side is inclined with respect to the horizontal plane, and the fourth side surface 5d is upward, The direction of the image displayed on the display unit 3 is changed by the image processing unit so that the side surface 5b side is down. The information processing unit 14 also includes a communication device unit that performs transmission / reception processing of the various antennas 7 to 10.

  Note that the display image orientation conversion signal of the image processing unit can also be obtained by operating the operation button 4.

  As described above, since the chassis 13 is made of a metal that hardly transmits electromagnetic waves, the various antennas 7 to 10 need to be arranged in the peripheral portion of the chassis 13 in consideration of transmission / reception characteristics. In order to simplify the wiring of the antennas 7 to 10 and to reduce the size, it is preferable that the peripheral portion of the chassis 13 is concentrated on one of the side surfaces 5a to 5d as much as possible. 6 is provided between the display unit 3 and the first side surface 5a facing the side 6a.

  Further, the handle 6 is made of only a resin that does not contain metal such as the chassis 13. Even if the various antennas 7 to 10 are arranged along the first side surface 5a, the handle 6 has no metal that blocks the electromagnetic waves, so that the electromagnetic waves of the antennas 7 to 10 transmitted and received by the communication device unit of the information processing apparatus 1 are absorbed and absorbed. Without being reflected, the transmission / reception characteristics of electromagnetic waves in the various antennas 7 to 10 can be improved.

  As described above, electromagnetic waves radiated when transmitting from various antennas 7 to 10 are easily absorbed by the human body. For this reason, when the various antennas 7 to 10 and the human body are close to each other, the SAR may exceed the standard of the Ministry of Internal Affairs and Communications. In order for the information processing apparatus 1 to satisfy the SAR standard, the various antennas 7 to 10 must be separated from the human body (abdomen and chest) by at least about 1 cm.

  Hereinafter, the positional relationship between the human body and the various antennas 7 to 10 in the usage state of the information processing apparatus 1 according to the present embodiment will be described with reference to FIGS. 3A to 3C. 3A to 3C are diagrams illustrating each use state of the information processing apparatus 1. In the present embodiment, the usage state of the information processing apparatus 1 will be described taking a medical site as an example. In addition, the case of inputting using the touch pen 17 to the tablet-type display unit 3 will be described, but the same applies to a finger other than the touch pen or an operation pen when a digitizer function is provided.

  As shown in FIG. 3A, when inputting patient information to an electronic medical record or the like using the touch pen 17, the user normally holds the information processing apparatus 1 by pressing the third side surface 5c against the user's abdomen or chest. And use it. In this case, since the user is separated from the various antennas 7 to 10 related to the SAR by the longitudinal length L (see FIG. 2) of the main unit 2, the information processing apparatus main body 1 satisfies the SAR standard. Can do.

  Also, when viewing vertically long information such as a diagnostic image, the user presses the second side surface 5b or the fourth side surface 5d against the user's abdomen or chest as shown in FIG. The processing apparatus 1 is gripped and used. In this case, as shown in FIG. 1, the various antennas 7 to 10 related to the SAR are arranged on the first side surface 5a that is substantially orthogonal to the second side surface 5b or the fourth side surface 5d that the user approaches, The closest WWAN antenna 7 is also arranged at an interval of at least about 1 cm from the fourth side surface 5d, and has a sufficient distance from the user as described above. For this reason, the information processing apparatus 1 can satisfy the SAR standard.

  As shown in FIG. 3C, when collecting blood from a patient, the user puts the collected blood into the container 18, affixes a seal with a barcode 19 to the container 18, and the barcode 19 is read by the barcode reader 11. By correlating the collected blood with the patient. Since the barcode reader 11 is arranged on the third side surface 5c side of the information processing apparatus main body 1 and is operated by the operation button 4, when the user reads the barcode 19, the handle 6 is placed on the abdomen or chest of the user. The information processing apparatus 1 is used in the pressed state. In this case, the various antennas 7 to 10 (see FIG. 1) related to the SAR are arranged in the vicinity of the first side surface 5a that is separated from the surface 16 of the handle 6 by a distance H (for example, 5 cm) shown in FIG. Therefore, the information processing apparatus 1 can satisfy the SAR standard.

  As described above, the information processing apparatus 1 according to the present embodiment can satisfy the prescribed SAR standard without reducing the transmission / reception sensitivity of the antennas 7 to 10 in all usage patterns.

  Moreover, since it is only necessary to arrange each of the transmission antennas 7 to 10 on one side surface, the cost can be suppressed and the wiring can be simplified. Furthermore, the various antennas 7 to 10 can be collected on the first side surface 5a, and a battery housing part and input / output terminals can be arranged on the other side surface.

  In the present embodiment, the both ends of the handle 6 are connected from both ends of the first side surface 5a, and the shape covering the first side surface 5a has been described as an example. However, between the user and the various antennas 7 to 10 is described. Any shape can be used as long as it can maintain a certain distance and functions as a handle. For example, as shown in FIG. 4, even if the handle 6b is substantially T-shaped, a certain distance can be maintained between the user and the various antennas 7 to 10, and the handle 6b can function as a handle. .

  In the present embodiment, the configuration in which the handle 6 protrudes from the first side surface 5a and is fixed has been described as an example. However, the information processing apparatus according to the present invention is not limited to this configuration. For example, in the case where the handle 6 can be stored in the first side surface 5a, the antennas 7 to 10 can be used even when the handle 6 is stored. A sensor that senses that the handle 6 is stored, or a configuration that can secure a distance of at least 1 cm from the sensor, and controls the electromagnetic radiation from the various antennas 7 to 10 when the handle 6 is stored. It may be configured to. Even in this configuration, the effect of reducing the SAR can be obtained.

  In the present embodiment, the configuration in which the barcode reader 11 is arranged in the vicinity of the third side surface 5c is shown. However, the present invention is not limited to this configuration. For example, an RFID reader / writer may be disposed together with the barcode reader 11.

  In the case where the RFID reader / writer is arranged in the vicinity of the third side surface 5c, the barcode reader 11 and the RFID reader / writer can be arranged at independent positions. However, it is not always necessary to provide both at independent positions, and both may be arranged at positions near one end of the third side surface 5c. For example, when reading a barcode or RFID tag with the handle 6 held by the user, the third side surface 5c of the information processing apparatus 1 is tilted. It is preferably arranged at the position of the barcode reader 11 in the present embodiment.

  In addition, when both the barcode reader 11 and the RFID reader / writer are provided, the configuration in which the bar code reader 11 and the RFID reader / writer are arranged at the position of the inclined fourth side surface 5c is preferable because it is convenient for the user.

  Further, in the above-described embodiment, the case where the information processing apparatus is used in a medical site has been described as an example, but for example, business use such as product management stored in a warehouse, rescue operation at a disaster site, The present invention can also be applied to personal uses such as games and navigation terminals via the antennas 7 to 10.

  The present invention has advantages that SAR can be reduced, costs can be reduced, and wiring can be simplified, and can be used as an information processing apparatus.
