  FIG. 1 is a perspective view showing an external appearance of a mobile phone 1 according to an embodiment of the present invention in an open state.

The mobile phone 1 is configured as a non-foldable mobile phone 1.
The cellular phone 1 has a front case 4 on which an input unit 10 and a display unit 8 are formed, and a rear case 5 constituting the opposite side portion. Hereinafter, the front case 4 and the rear case 5 are collectively referred to as a housing 2.

The front case 4 and the rear case 5 are fixed to each other by screws or the like, and an accommodation space for accommodating various electronic members is formed in a space formed between the front case 4 and the rear case 5.
The front case 4 and the rear case 5 are made of resin, for example.

The input unit 10 is provided with a plurality of input keys, and the user gives instructions and inputs to the mobile phone 1 by pressing the input keys.
1, the input unit 10 is disposed only on the surface of the front case 4, but includes side keys disposed on the right side surface 11, the left side surface 12, the upper side surface 20, and the lower side surface 21 of the housing 2. It is.

The display unit 8 is for displaying various information such as the state of the mobile phone 1, the user's operation content, the destination telephone number, the content of the e-mail, and the game screen.
The display unit 8 includes an LCD (liquid crystal display), an OLED (Organic light-emitting diode: organic EL), and the like.

  When indicating the direction, the direction from the rear case 5 toward the front case 4 is referred to as the front surface direction (the front side in FIG. 1), and the direction from the front case 4 toward the rear case 5 is the rear surface direction (see FIG. 1 is referred to as “the direction of the back of the page”.

Further, the side surface located in the direction from the input unit 10 toward the display unit 8 is defined as the upper side surface 20, and the side surface located in the direction from the display unit 8 toward the input unit 10 is defined as the lower side surface.
The direction toward the upper side surface 20 is referred to as the upper side surface direction (the right direction in FIG. 1), and the direction toward the lower side surface 21 is referred to as the lower side surface direction (the left direction in FIG. 1).

Further, when the mobile phone 1 is viewed with the display unit 8 facing up and the input unit 10 facing down, the side surface coming to the right side is referred to as the right side surface 11, and the side surface coming to the left side is referred to as the left side surface 12.
The direction toward the right side surface 11 is referred to as the right side surface direction (the direction below the paper surface in FIG. 1), and the direction toward the left side surface 12 is referred to as the left side surface direction (the direction above the paper surface in FIG. 1). .

An indicator 13 is disposed at a position in the upper side surface direction of the front case 4. The indicator 13 is used to allow the user to recognize information such as incoming calls, incoming mails, and arrival of alarm times.
As a method of making it recognize, it is based on the method by making the indicator 13 light-emit in a specific color, or making it light.
The indicator 13 is made transparent and translucent.

A pointer lens 14 is disposed on the indicator side of the upper side surface 20. Pointer light is projected through the pointer lens 14.
For example, as shown in FIG. 1, the pointer light is projected onto a screen 31 and used to indicate various characters, graphics, and the like.

  2 is a cross-sectional view taken along the line II-II in FIG.

A printed circuit board 16 is disposed inside the housing 2 constituted by the front case 4 and the rear case 5.
Various electronic devices for driving the mobile phone 1 are mounted on the printed circuit board 16.
In the present invention, an LED 15 as a light emitting unit is mounted on the printed circuit board 16. The LEDs 15 are mounted with blue, red, and green LEDs 15, and the light emission amounts of the LEDs 15 are independently controlled by a pointer / indicator control unit 53 described later.
Thereby, the LED 15 can generate light of any color.

The light generated by the LED 15 is utilized in two directions.
One is the light used in the indicator 13.
Specifically, the light generated by the LED 15 is incident on the indicator 13 portion formed on the front case 4. The light that has entered the indicator 13 passes through the inside of the indicator 13 and is emitted to the outside of the mobile phone 1 from the surface of the indicator 13 exposed to the outside of the housing 2.
The user can recognize the emitted light and know various states of the mobile phone 1 (incoming calls, incoming e-mails, lighting of schedule alarms).
The other is light used as a pointer.
Specifically, the light generated by the LED 15 passes through the light blocking unit 17 and is collected by the pointer lens 14. The light collected by the pointer lens 14 is radiated to the outside of the mobile phone 1 from the surface where the pointer lens 14 is exposed to the outside of the housing 2.
The emitted light travels straight until it enters the screen 31 or the like, and the light is projected onto the incident screen 31 or the like.
The user recognizes the light projected on the screen 31 or the like. Thereby, the cellular phone 1 of the present invention can exhibit a pointer function.
Note that the light that exhibits the pointer function is formed by the LED 15, and the amount of light of three types of red, blue, and green can be adjusted. Therefore, the color of the pointer can be arbitrarily generated.

The light blocking unit 17 disposed between the LED 15 and the pointer lens 14 is performed by inserting a light blocking plate made of a material that does not transmit light through the light path mechanically.
However, the present invention is not limited to this. For example, a liquid crystal panel that does not transmit light when energized can be used.
That is, any method can be used as long as it can block light emitted from the LED 15.

  FIG. 3 is a block diagram showing a signal processing system of the mobile phone 1 shown in FIGS.

  As shown in FIG. 3, the mobile phone 1 includes a control unit 57 that is the center of control and processing, a communication unit 51, an input unit 10, a pointer / indicator control unit 53, a display unit 8, and a storage unit. Each of 56 is connected and configured in common to a system bus 58 having a plurality of lines for address, data, and control.

  The communication unit 51 captures a wireless communication system, performs wireless communication with a base station connected to a communication network, and transmits and receives various data. The various types of data include file data downloaded from a download site on the web, voice data during a voice call, mail data during mail transmission / reception, web page data during web browsing, and the like.

The input unit 10 receives user instructions input from the numeric keypad and other parts.
In the input unit 10, for example, keys to which various functions are assigned such as a power key, a call key, a numeric key, a character key, a direction key, a determination key, a call key, a function key, and a side key are arranged.
When these keys are operated by the user, a signal corresponding to the operation content is generated and output to the control unit 57 as a user instruction.

The display unit 8 is configured using, for example, an LCD or an OLED (Organic light-emitting diode (organic EL)), and displays an image corresponding to the video signal supplied from the control unit 57.
The display unit 8 includes, for example, a telephone number of a transmission destination at the time of wireless transmission by the communication unit 51, a telephone number of a transmission source at the time of reception, contents of received mail and transmitted mail, date, time, remaining battery level, success / failure of transmission, standby Display the screen.

The storage unit 56 stores various data used for various processes of the mobile phone 1.
The storage unit 56 includes, for example, a computer program executed by the control unit 57, an address book for managing personal information such as a telephone number and an e-mail address of a communication partner, an audio file for reproducing a ring tone and an alarm sound, and a standby An image file for a screen, various setting data, and temporary data used in the program processing are stored.
The storage unit 56 also has a function of storing the current color emitted by the LED 15.

  The storage unit 56 is configured by, for example, a nonvolatile storage device (nonvolatile semiconductor memory, hard disk device, optical disk device, etc.), a random accessible storage device (eg, SRAM, DRAM), or the like.

The pointer / indicator control unit 53 controls the LED 15 and the light blocking unit 17.
The control of the LED 15 is based on a command from the control unit 57, and controls the amount of light emitted from the LED 15 to generate light of the color commanded by the control unit 57.
The control of the light blocking unit 17 blocks the light generated by the LED 15 so as not to enter the pointer lens 14.
By controlling the light blocking unit 17 and blocking the light, the light generated by the LED 15 can be used only for the indicator.
Conversely, the light generated by the LED 15 can be used for the pointer function by controlling the light blocking unit 17 and transmitting the light.

The control unit 57 comprehensively controls the overall operation of the mobile phone 1.
That is, in the control unit 57, various processes of the mobile phone 1 (voice calls performed via a circuit switching network, creation and transmission / reception of e-mails, browsing a download site on the Internet web, etc.) The operation of each block described above (transmission / reception of signals in the communication unit 51, display of images on the display unit 8, etc.) is controlled so as to be executed according to an appropriate procedure accordingly.
Furthermore, the control unit 57 includes a computer (microprocessor) that executes processing based on a program (operating system, application program, etc.) stored in the storage unit 56, and has been described above according to the procedure instructed in this program. Execute the process.
That is, the control unit 57 sequentially receives instruction codes from programs such as an operating system and application programs stored in the storage unit 56 and executes processing.

Further, the control unit 57 automatically selects the color of the LED 15 according to a command from the user and controls the pointer / indicator control unit 53. Alternatively, the user designates the light emission color of the LED 15 and instructs the pointer / indicator control unit 53 based on it.
Furthermore, the control unit 57 may have a role of determining the color emitted by the LED 15 of the own device based on the color designation information signal transmitted from the other mobile phone 1 transmitted from the communication unit 51 (the first will be described later). See 1 variant).

  Further, the light color used last time may be stored in the storage unit 56 so that the previous color can be automatically selected when the pointer function is used.

Furthermore, depending on user preferences and laws or customs, certain colors may not be used or used. For example, since a red laser is used for aiming a gun or the like, such a color pointer may not be legally or customarily usable.
For such a case, information indicating that a certain color cannot be used is stored in advance in the storage unit 56 of the mobile phone 1 so that the control unit 57 cannot select the color. It is.

By configuring as described above, the mobile phone 1 can exhibit a pointer function by the light of the LED 15 instead of the laser beam.
Since the light of the LED 15 has lower energy than the laser beam, there is an advantage that even if light enters the human eye, damage such as blindness is not given to the human.
Furthermore, since the LED 15 is extremely cheaper than electronic components that generate laser beams, there is an advantage that the pointer function can be mounted on the mobile phone 1 at a low cost.
Further, since the LED 15 can be used for both the pointer and the indicator, the number of components can be reduced as compared with the case where an electronic component that generates a laser beam is separately mounted. This contributes to manufacturing cost reduction.

In addition, it is difficult to change the color of the laser beam light and requires a large amount of cost. However, if the LED 15 is equipped with three types of LEDs 15 of red, blue, and green, any color can be created. Can do.
Thus, if each user is notified of the color of the light used for the pointer, it is possible to easily recognize who is pointing to where, and convenience is increased.

<First Modification>
A more preferable modification is shown.
FIG. 4 is an explanatory diagram illustrating a first modification.
4 is a cross-sectional view of the same portion as that shown in FIG.

As shown in FIG. 4, the reflector 24 is disposed at a position opposite to the position where the pointer lens 14 of the LED 15 is located.
By doing in this way, the light radiate | emitted from LED15 can be efficiently collected in the lens 14 for pointers.
The shape of the reflecting plate 24 can be arbitrarily determined as long as light can be efficiently collected on the pointer lens 14.
By the way, although the reflecting plate 24 condenses the light on the pointer lens 14, it does not need to condense the light on the indicator 13 side. This is because the indicator 13 uses the light of the LED 15 but does not require strong light unlike the pointer function, and therefore there is often no need to collect the light by the reflector 24. Of course, if it is desired to use strong light for the indicator 13, the light may be condensed using the reflector 24.

Further, as shown in FIG. 4, it is further advantageous to provide a projection image generation unit 23 in the light blocking unit 17 portion.
In other words, the projected image generation unit 23 displays an arrow or pointer user identification display (name, identification number, etc.).
Thereby, an identification display of an arrow or a pointer user can be displayed on the screen 31.
Then, in the case of the arrow, it becomes easy to understand which part is pointing, and in the case of the identification display, it becomes possible for the user and others to recognize who is pointing with the pointer.

<Second Modification>
In the above method, it is assumed that there is one mobile phone 1 having a pointer function.
However, as shown in FIG. 5, the mobile phone 1 having a plurality of pointer functions may be used at a time.

In this case, a plurality of pointers appear on the same screen 31 at the same time. This makes it necessary to distinguish which user is pointing to which part because it is unclear.
As the method, there is a method of assigning a different emission color of the LED 15 for each mobile phone 1.
The method will be described below.

  FIG. 5 shows a state in which a plurality of mobile phones 1 of the present invention are used.

As shown in FIG. 5, on the screen 31, the three mobile phones 1 including the parent terminal, the child terminal 1, and the child terminal 2 are pointed by pointers. However, it is not intended to limit to three units, but can be increased or decreased as necessary. In particular, in the present invention, since the light emission color of the LED 15 can be arbitrarily selected, the number of mobile phones 1 can be increased within a range that can be distinguished and identified by the user.
Among these, the cellular phone 1 which is the parent terminal has a function of determining the emission color of the LED 15 of the child terminal 1 and the child terminal 2.

  FIG. 6 is a block diagram showing a signal processing system in which the parent terminal determines the emission color of the LED 15 of the child terminal 1, the child terminal 2, and the parent terminal itself.

  The basic operation of each member in the cellular phone 1 of the parent terminal, the child terminal 1 and the child terminal 2 is the same as that described in FIG.

First, each user of the cellular phone 1 of the parent terminal, the child terminal 1 and the child terminal 2 performs a key input for automatically determining the emission color of the pointer function by the input unit 10 and the child terminal input unit 110.
This input signal is transmitted from the input unit 10 (slave terminal input unit 110) to the control unit 57 (slave terminal control unit 157).
Receiving this, the control unit 57 (child terminal control unit 157) detects the other mobile phone 1 that is also receiving the color designation command of the emission color of the pointer function, and then communicates with the communication unit 51 (child terminal communication unit 151). ) To communicate.
Then, each mobile phone 1 can find the mobile phone 1 that has also received the color designation command.
If it does so, the control part 57 of the mobile telephone 1 of a parent | terminal terminal will determine that the light emission color of an own machine and the light emission color of the sub-terminal 1 do not become the same. Various determination methods are conceivable, but there may be a method in which the order is determined in advance such as red, blue, green, orange,. At this time, a method of storing colors that cannot be used or are not desired to be used may be used at the same time.
The determined emission color information of the mobile phone 1 of the child terminal 1 is transmitted to the mobile phone 1 of the child terminal 1 using the communication unit 51.
The slave terminal communication unit 151 receives the transmitted communication. The emission color information is stored in the child terminal storage unit 156.
The child terminal pointer / indicator control unit 153 causes the child terminal LED 115 to emit light based on the stored emission color information.
As a result, the pointer display in the emission color determined by the mobile phone 1 of the parent terminal is made on the mobile phone 1 of the child terminal 1.

Further, the light emission color information used for the mobile phone 1 of the own device (parent terminal) and the child terminal 1 is stored in the storage unit 56 so as not to be allocated redundantly.
Further, the control unit 57 also determines the emission color of the child terminal 2, stores it in the storage unit 56, and notifies the mobile phone 1 of the child terminal 2 through the communication unit 51.
As a result, the mobile phone 1 of the child terminal 2 also performs pointer display using the emission color determined by the parent terminal.

  Note that the cellular phone 1 of the parent terminal also displays a pointer with the light emission color determined by its own control unit 57.

  FIG. 7 is an explanatory diagram illustrating a procedure in which the parent terminal determines the emission color of the LED 15 of the child terminal 1, the child terminal 2, and the parent terminal itself.

In step ST <b> 11, the user inputs to the mobile phone 1 that the light emission color is determined as the parent terminal.
At almost the same time, the user of the mobile phone 1 of the child terminal 1 and the child terminal 2 also inputs that the parent terminal as a child terminal receives the color determination of the emission color (step ST31 and step ST51).
Then, in step ST12, step ST32, and step ST52, communication is performed by wireless communication, and the parent terminal grasps the number of mobile phones 1 that receive color designation of the emission color as a child terminal.

In step ST13, the control unit 57 of the parent terminal determines its own emission color and the emission color of the child terminal 1.
Next, in step ST14, the control unit 57 of the parent terminal stores the determined emission color of the own device (parent terminal) and the emission color of the child terminal 1 in the storage unit 56.
The determined emission color of the child terminal 1 is notified to the mobile phone 1 of the child terminal 1 through the communication unit 51 in step ST15.
In step ST <b> 35, the child terminal 1 receives the emission color through the child terminal communication unit 151 and stores it in the child terminal storage unit 156.

Further, in step ST16, the control unit 57 of the parent terminal selects and determines the emission color of the child terminal 2 by selecting a color other than the stored own device (parent terminal) and the emission color of the child terminal 1.
Next, in step ST <b> 17, the control unit 57 of the parent terminal stores the determined emission color of the child terminal 2 in the storage unit 56.
Then, the determined emission color of the child terminal 2 is notified to the mobile phone 1 of the child terminal 2 through the communication unit 51 in step ST18.
In step ST58, the child terminal 2 receives the emission color through the child terminal communication unit 151 and stores it in the child terminal storage unit 156.

Finally, in step ST19, step ST39, and step ST59, each mobile phone 1 of the parent terminal, the child terminal 1, and the child terminal 2 has the LED 15 and the child light emitting colors stored in the storage unit 56 and the child terminal storage unit 156. Each terminal LED 115 is caused to emit light.
At the same time, the light blocking unit 17 and the slave terminal light blocking unit 117 are controlled to release the light blocking.

  With this configuration, even when the pointers of the plurality of mobile phones 1 are simultaneously displayed on the screen, the user can recognize who the pointer is.

  In the above second modification, communication is performed using radio communication for telephone communication, but the present invention is not limited to this. Specifically, near field communication such as infrared communication or Bluetooth (registered trademark of Bluetooth SIG, Inc.) may be used. In this case, the emission color may be sequentially determined such as the parent terminal and the child terminal 1, the parent terminal and the child terminal 2, and so on.

<Third Modification>
In the method according to the second modification, the colors of the pointers used by each user do not overlap, so that it is possible to easily recognize that the display is performed by pointers by different persons.
However, although distinction is possible, there is a problem that it is not easy to know who the pointer is.
As a means for solving the problem, there may be a method in which each person applies for the color after the light emission color is designated according to the second modification.
However, the method is roundabout.
In order to solve such a problem, the following third modification can be considered. A third modification will be described below.

  FIG. 8 is an explanatory diagram illustrating a third modification.

As shown in FIG. 8, the projected image 32 is often projected simultaneously by the projector 30 on the screen 31 on which the pointer display is performed.
In this case, if the user of the color of each pointer is shown on the projection screen of the screen 31, the user or the like can know who is the user of the pointer.

  FIG. 9 is a display example displayed on the screen 31.

As shown in FIG. 9, an identification display 33 is provided at the corner of the projection image 32 projected on the screen 31.
As shown in FIG. 9, the identification display 33 is the name of the person who uses the color and the pointer. However, the present invention is not limited to this, and various methods are possible.
Specifically, it may be a number such as an identification ID instead of a name. Instead of the name, it may be a mark or a design. The color may be filled with the color instead of the character.

  FIG. 10 is a block diagram showing a signal processing system when notifying the projector 30 of the emission color and user information (identification display 33) corresponding to the emission color.

The light emission colors of the parent terminal, the child terminal 1 and the child terminal 2 are determined by the method of the second modification described above.
Further, when communication for determining the emission color is performed, information on the identification display 33 of the child terminal 1 and the child terminal 2 is simultaneously notified to the parent terminal.
The information on the identification display 33 is user name information stored in each mobile phone 1.
However, the present invention is not limited to this, and it is also possible to input or select when inputting (step ST11, step ST31, step ST51 in FIG. 7) to designate or receive a light emission color. It can also be specified in advance.

After such processing is performed, the cellular phone 1 as the parent terminal communicates with the projector 30 and notifies the projector 30 of the emission color information and the corresponding identification information.
Upon receiving the notification, the projector 30 performs display corresponding to the notification.
Specifically, the user uses the input unit 10 to input to the projector 30 the identification display 33 on the mobile phone 1 of the parent terminal.
In addition, the user inputs to the projector 30 that the information on the identification display 33 is received from the mobile phone 1 of the parent terminal via the projector input unit 210.

Then, the communication unit 51 and the projector communication unit 251 perform communication, and the communication unit 51 notifies the projector communication unit 251 of the emission color information and the identification display 33 information stored in the storage unit 56.
Receiving this, the projector control unit 257 stores the information in the projector storage unit 256. Further, the projector control unit 257 adjusts the display position and the like, and gives a command to display the emission color and the identification display 33 on the projector projection unit 208 so that the display can be easily understood.

  FIG. 11 is an explanatory diagram showing internal processing when the projector 30 performs the emission color and identification display 33.

In step ST71, the determination of the luminescent color displayed by each mobile phone 1 (parent terminal, child terminal 1, child terminal 2) has been completed. In step ST71, it is determined to determine the contents of the identification display 33 of the mobile phone 1 that displays the display color.
These pieces of information are held by the mobile phone 1 of the parent terminal.
Then, in step ST72, the user inputs to the projector 30 the identification display 33 on the projector 30 on the mobile phone 1 of the parent terminal.
At the same time, in step ST92, the user inputs to the projector 30 that the identification display 33 is performed.

In step ST73, the mobile phone 1 of the parent terminal searches for the projector 30 by wireless communication.
In step ST93, projector 30 searches for mobile phone 1 of the parent terminal by wireless communication.

In step ST74, the cellular phone 1 of the parent terminal transmits the emission color information and the identification display 33 information.
In step ST94, the projector 30 receives and stores the emission color information and the identification display 33 information.

  In step ST95, the projector 30 projects the emission color information and the identification display 33 information using the projector projection unit 208.

  By configuring as described above, the user can easily know which color is used by which user.

According to the above embodiment, the mobile phone 1 of the present invention has the housing 2 and the LED 15 disposed inside the housing 2.
And it has the indicator 13 which radiates | emits and alert | reports the light which LED15 emits outside the housing | casing 2, and the lens 14 for pointers which condense and radiate | emits the light which LED15 emits outside the said housing | casing 2.
With such a configuration, the mobile phone 1 can exhibit a pointer function by the light of the LED 15 instead of the laser beam.
Since the light of the LED 15 has lower energy than the laser beam, there is an advantage that even if light enters the human eye, damage such as blindness is not given to the human.
Furthermore, since the LED 15 is extremely cheaper than electronic components that generate laser beams, there is an advantage that the pointer function can be mounted on the mobile phone 1 at a low cost.
Further, since the LED 15 can be used for both the pointer and the indicator, the number of components can be reduced as compared with the case where an electronic component that generates a laser beam is separately mounted. This contributes to manufacturing cost reduction.

Between the LED 15 inside the housing 2 and the pointer lens 14, a light blocking unit 17 that blocks light emitted from the light emitting unit is disposed.
With such a configuration, the LED 15 can be used only as an indicator when not used as a pointer.

The light blocking unit 17 blocks light based on control from the control unit 57.
With such a configuration, the pointer and the indicator 13 display can be switched as necessary.
