Description

  The present invention relates to an information processing apparatus, and more particularly to an information processing apparatus that achieves both power saving and security enhancement with a single sensor.

  In recent years, crimes for intrusion into houses have increased, and various crime prevention techniques have been proposed. Since introduction of an advanced security system is costly, a thermal automatic switch has been proposed that turns on illumination when a person approaches the entrance using a human sensor that detects the presence or absence of a human body. In addition, using a pyroelectric human sensor that detects a human body in a detection area by detecting a heat ray radiated from the human body, when a human body is detected, a normal mode in which illumination is turned on for a predetermined time, and light or There has been proposed a thermal automatic switch with an absence mode function that switches between an absence mode that threatens a suspicious person with sound (see, for example, Patent Document 1).

In addition, as a crime prevention technique against theft of a PC (personal computer) containing personal information or confidential company information, an information processing apparatus provided with a sensor for detecting the state of the apparatus main body such as a gyro sensor has been proposed (for example, Patent Document 2).
Japanese Patent Laid-Open No. 2007-200046 JP 2000-155876 A

  However, the information processing apparatus provided with the sensor for detecting the apparatus main body taking-out state as described above is an invention that strengthens the security of the information processing apparatus after being taken out, so that it can take some measures before being taken out. Is desirable. Moreover, it is necessary to provide a special sensor such as a gyro sensor for such security enhancement, which is expensive. In the thermosensitive automatic switch with absence mode function using a human sensor, mode switching cannot be performed automatically, and it is difficult to cope with the situation according to the situation.

  Therefore, it is desired to enhance security by making use of an existing configuration or a configuration with other uses.

  The present invention has been made in view of such a situation, and an object thereof is to realize both power saving and security enhancement with a single sensor.

An information processing apparatus according to the present invention includes a display unit casing and an operation unit casing, and the display unit casing is connected to the operation unit casing so as to be openable and closable. A human sensor for detecting the presence or absence of a human body, provided on a surface exposed when the housing is opened, provided on the upper side of the display when the display housing is opened; The detection means for detecting the opening / closing of the display unit casing and the first mode in which the information processing apparatus consumes less power than the normal operation state or the second mode in which a predetermined security operation is performed are switched. Mode switching means, and the switching by the mode switching means is detected by the detection means that the display unit housing is open, and when the human sensor detects the absence of a human body, Switch to the first mode, If the display housing by means output that is closed is detected, switching to the second mode, the human sensor in response to opening and closing of the display housing, Rukoto changing sensing direction It is characterized by.

  According to the present invention, both power saving and security enhancement can be realized with one sensor.

  Embodiments of the present invention will be described below in detail with reference to the drawings. The embodiments described below are preferred embodiments of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. As long as there is no description of the effect, it is not restricted to these aspects.

  FIG. 1 shows a perspective view of an information processing apparatus according to an embodiment of the present invention. The information processing apparatus 1 according to the present embodiment is an open / close type information processing apparatus, and the display unit housing 3 is provided with a display unit. In this embodiment, an LCD (Liquid Crystal Display) is used as an example of the display unit. It is connected to the operation unit housing 4 so as to be opened and closed. Note that the present invention may be an information processing apparatus including two or more housings, and as shown in FIG. 1, the other is not limited to the display unit and the other is not the operation unit.

  A sensor 2 is installed in the display unit housing 3 of the information processing apparatus 1. The sensor 2 detects the presence or absence of a human body. Specifically, it is a human sensor that detects a human body. When a human body is detected, it is known that the human body is present, and when the human body cannot be detected, the absence of the human body is known. As a specific example of the human sensor, a pyroelectric sensor or a distance measuring sensor can be considered. The sensor 2 shown in FIG. 1 is built in the information processing apparatus 1, but may be a removable external sensor. Further, the human sensor is preferably the upper side portion of the LCD 7 provided on the surface (front surface) exposed when the display unit housing 3 is opened, and is installed at the center portion of the upper side in FIG. This is because the distance difference B described later is as large as possible.

  The sensor 2 functions within a range in which the presence of the user 5 (the presence of a human body) can be detected when the information processing apparatus 1 is used, as shown in FIG. When it is detected that the user 5 is absent (absence of a human body), the information processing apparatus is set to a minimum power consumption state by turning off some functions of the apparatus such as the LCD. It is characterized by switching to the mode (hereinafter also referred to as a power saving mode). In the power saving mode, control for reducing the power consumption of the information processing apparatus is performed. For example, the CPU is turned off, the operation speed is lowered, and the display unit such as the LCD is turned off.

  FIG. 2B shows a case where the display unit housing 3 is closed. In this case, it is possible to detect far (distance difference B) from the detection range at the time of use shown in FIG. As a result, it is possible to detect whether or not a suspicious person has passed around and to enhance security. Particularly in the case of an information processing apparatus used in an office, if a human body is detected at midnight, it can be considered as detection of a suspicious person.

  Next, the sensor 2 will be described in detail. When the sensor 2 is fixed to the information processing apparatus 1, a human body can be detected in a state where the display unit housing 3 is opened as shown in FIG. When the display unit housing 3 is closed as shown in FIG. 2, the direction of the sensor is downward. Therefore, when the sensor 2 is a distance measuring sensor, as shown in FIG. 3, it is conceivable to mount a mirror (for example, a 45 ° mirror) on the operation unit housing 4 to change the sensor reaction angle. Thereby, as shown in FIG. 4, a human body can be detected with respect to the front direction.

  Further, the sensor 2 may be rotatably installed as shown in FIG. 5 and may be moved by an electric motor (not shown). Thereby, even when the display unit housing 3 is closed, the sensor 2 can be directed forward (see FIG. 6). The movement of the sensor 2 may be interlocked with the opening / closing of the display housing 3 and automatically rotated to a predetermined angle in accordance with the opening / closing of the display housing 3.

  Next, a functional configuration of the information processing apparatus 1 according to the present embodiment will be described. FIG. 4 is a functional block diagram of the information processing apparatus 1. The information processing apparatus 1 includes a sensor 2, a CPU (Central Processing Unit) 10, a ROM (Read Only Memory) 11, a RAM (Random Access Memory) 12, a mode switching unit 15, and a display unit housing 3 opening / closing detection unit 16. The

  The CPU 10 controls the entire information processing apparatus 1 in association with the ROM 11 and the RAM 12. The ROM 12 stores in advance a control program for the information processing apparatus 1 and various application programs. The CPU 10 controls each functional block based on a control program stored in the ROM 11. In addition, activation / stop and control of various application programs stored in the ROM 11 are performed.

  The mode switching unit 15 detects that the display unit housing 3 is opened by the display unit housing 3 open / close detection unit 16 and sets the power saving mode when the sensor 2 cannot detect the human body. For example, the LCD is turned off.

  On the other hand, when the display unit housing 3 opening / closing detection unit 16 detects that the display unit housing 3 is closed, the mode switching unit 15 performs a second mode for performing a predetermined security operation (hereinafter referred to as security mode). Switch to The predetermined security operation will be described later. Note that switching to the security mode can be considered to further add a time setting condition such as a midnight time zone.

  When the human body is detected by the sensor 2 in the security mode, a suspicious person is detected by threatening with an alarm sound from an output unit (not shown), or the abnormality occurrence notifying unit 20 shown in FIG. A predetermined security operation such as notifying the management server of occurrence of an abnormality is performed.

  FIG. 9 shows a flowchart showing the operation process of the information processing apparatus 1 according to this embodiment. When it is detected that the display housing is closed (step S1 / Yes), the mode is switched to the security mode (step S2). In this case, when the human body is detected by the sensor 2 (step S3 / Yes), threatening And security operations such as notification of abnormality occurrence are performed (step S4).

  On the other hand, when it is detected that the display unit housing is open (step S1 / No) and no human body is detected by the sensor 2 (step S5 / No), the mode is switched to the power saving mode (step S6). ).

  In this way, paying attention to the change of the detection range by one sensor by opening and closing the display unit housing 3, the switching of the mode is interlocked with the opening and closing of the display unit housing 3 so that each sensor can By playing an appropriate role in the mode, both power saving and security enhancement can be realized with one sensor.

  The program for the CPU to execute the processing shown in the flowchart of FIG. 9 constitutes a program according to the present invention. As a recording medium for recording the program, a semiconductor storage unit, an optical and / or magnetic storage unit, or the like can be used. By using such a program and a recording medium in a system having a configuration different from that of each of the above-described embodiments and causing the CPU to execute the program, substantially the same effect as the present invention can be obtained.

  Although the present invention has been specifically described above based on the preferred embodiments, it is needless to say that the present invention is not limited to the above-described ones and can be variously modified without departing from the gist thereof.
