Benefits of technology

[0024] In this portable information apparatus having communications tools, the transmission functions of the wireless transmission / reception section may be automatically enabled / disenabled depending on which of the communication prohibition signal and / or the communication permission signal are / is received from the external facility. Accordingly, the transmission functions of the portable information apparatus may be automatically turned off if the carrier of the portable information apparatus has forgotten to do so. Thus, operations that do not require transmission of electromagnetic waves can be performed without causing a nuisance to others in a public facility.
[0026] Thus, the portable information apparatus having such communication functions can be used to receive urgent information even when the transmission functions of the wireless transmission / reception section are disenabled.
[0036] In this control system, the communication prohibition signal and / or the communication permission signal are / is much weaker than the electromagnetic waves transmitted from the wireless transmission / reception sections of the portable information apparatuses that they are less likely to affect other apparatuses that are easily influenced by strong ambient electromagnetic waves.
[0044] Thus the apparatus equipped with the controller can prohibit ambient portable information apparatuses to transmit electromagnetic waves by transmitting the weak communication prohibition signal and / or the weak communication permission signal without affecting the apparatus itself.

Problems solved by technology

As a result of dissemination of such portable information apparatuses, strong electromagnetic waves are emitted everywhere for communications, thereby posing serious problems to devices such as cardiac pace-makers that can fail under strong ambient electromagnetic waves.
Consequently, it is difficult to resort to the sense of morality of the carriers to turn off the portable information apparatuses.

first embodiment

[0050] Referring now to FIG. 1, there is shown in block diagram the invention in the form of a portable information apparatus having communications tools, like a cellular phone. As shown in FIG. 1, a cellular phone 10 comprises:

[0051] a wireless transmission / reception section 11 for transmitting / receiving electromagnetic signals for communication with an external transmission / reception apparatus such as a base station;

[0052] an operation section 12 for performing various operations;

[0053] a display section 13 for displaying operational status of an operation made by the operation section 12 and the status and the results of transmission / reception made by the wireless transmission / reception section 11; and

[0054] a control section 14 having a CPU and a memory and connected with the wireless transmission / reception section 11, the operation section 12, and with the display section 13, for controlling overall actions of the cellular phone. The operation section 12 is provided, along w...

second embodiment

[0064] Referring to FIG. 2, there is shown in block diagram a portable information apparatus having communications tools, such as a cellular phone, along with a control system for controlling the apparatus.

[0065] As seen in FIG. 2, a cellular phone 20 comprises:

[0066] a wireless transmission / reception section 21 for transmitting / receiving electromagnetic signals for communication with an external wireless transmission / reception apparatus;

[0067] an operation section 22 for performing various operations;

[0068] a display section 23 for displaying status of operations made by the operation section 22, and status and the results of transmission / reception operations made by the wireless transmission / reception section 21; and

[0069] a control section 24 having a CPU and a memory and connected with the wireless transmission / reception section 21, the operation section 22, and the display section 23, for controlling overall actions of the cellular phone. In addition to a power supply switc...

third embodiment

[0082] Referring to FIG. 3, there is shown a structure of the invention, in the form of a control system for controlling portable information apparatuses having communications tools.

[0083] A prohibition signal transmitter 41 shown in FIG. 3 is installed in a public place e.g. a train station for transmitting a communication prohibition signal and / or a communication permission signal to prohibit and / or permit operation of transmission functions of cellular phones. The electromagnetic wave transmitted from the prohibition signal transmitter 41 is weak enough (e.g. weak FM waves) not to cause malfunctions of electromagnetically susceptible apparatuses, so that the waves are necessarily weaker than the waves transmitted from cellular phones.

[0084] The prohibition signal transmitter 41 may be coupled with various sensors and data means which operate under specified conditions. For example, the prohibition signal transmitter 41 may be provided with an infrared sensor 42 for sensing a hum...

Abstract

A portable information apparatus 20 having communications tools is provided with a switch 22a for instructing enablement / disenablement of transmission functions of the wireless transmission / reception section 21 of the portable information apparatus 20. The portable information apparatus 20, upon receipt of a transmission prohibition signal from an prohibition signal transmitter 31 installed in a public facility 30, determines whether the transmission functions must be disenabled and automatically controls enablement / disenablement of the transmission functions. The portable information apparatus is thus automatically turned off even when the carrier of the apparatus has forgotten to turn off the transmission functions, thereby allowing the carrier to perform necessary operations not involving transmission of electromagnetic waves without causing a nuisance to others.

Description

FIELD OF THE INVENTION [0001] The invention relates to a portable information apparatus having communications tools, e.g. a cellular phone and a personal handyphone system (PHS), and to a control system for controlling such portable information apparatus, and further to an apparatus equipped with a controller for controlling such portable information apparatus. BACKGROUND OF THE INVENTION [0002] Portable telephone systems such as cellular phones have extensively diffused among people because of the convenience of such system that the carrier of the system can be paged wherever he is, and he can call up his partner from anywhere. Particularly, because of recent improvements of cellular phones and infrastructures of cellular phone systems, cellular phones have functionally evolved beyond mere telephonic devices and have become versatile portable information apparatuses having information processing functions to deal with e-mail and retrieve information. [0003] These portable informati...
