Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides, for example, a xenon tube as a light emitting means behind a telephone so that the light emitting means is turned on or off when an incoming call or the like from a telephone line is received. Related to telephones that flash. 2. Description of the Related Art Generally, when a bell signal arrives at a line of a central office, the telephone recognizes the arrival of the bell signal audibly by a ring sound output from a speaker built in the telephone body. You can do it. Depending on the model, the arrival of the bell signal can be recognized by visual means, for example, by turning on or blinking an LED embedded in the dial button, in addition to outputting a ring sound from a speaker. Some have been done as such. In some cases, an additional device is connected to the outside of the telephone body, and the arrival of a bell signal is displayed by turning on or off a neon tube, a light bulb, or a xenon tube provided in the additional device. By the way, in such a device that can recognize the arrival of a bell signal by such light, the arrival of the bell signal can be recognized not only by hearing but also by visual sense, so that the incoming call can be confirmed reliably even when there is a lot of noise. In addition to the effect, by setting the so-called silent mode, the output of the ring sound from the speaker is stopped, and the arrival of the bell signal only by light can be recognized. Is effective in suppressing that sleep is disturbed by the bell sound. However, in the above-mentioned conventional telephone, when an attempt is made to notify the arrival of the bell signal by the light emission of the LED when the silent mode is set, the light emission of the LED is weak. When there is an incoming call,
Failure to recognize the light emission if the front of the telephone is not within the field of view of the user, and it is difficult to recognize the light emission of the LED even during the day, even when the telephone is within the field of view. was there. Further, in the above-described additional device, when using a light bulb or a xenon tube,
Relatively intense light emission makes it easier to recognize lighting or blinking than LEDs, but requires extra space in addition to the telephone, and there are restrictions due to additional equipment when moving the telephone. In addition, since the light from the light source directly enters the eyes, there is a problem that it is not easy on the eyes especially when the light is caused by the discharge of the xenon tube. [0007] The present invention has been made in view of such circumstances, and accurately recognizes the arrival of a bell signal by light.
Another object of the present invention is to provide a telephone which can be performed in a wide area and which is easy on the eyes. In order to achieve the above object, a telephone according to the present invention has an incoming call detecting means for detecting an incoming call, and a light emitting means for emitting light based on a detection output from the incoming call detecting means. And a light emitting window provided at a position where direct viewing is avoided in order to visually recognize light from the light emitting means as indirect light, and light guide that emits light from the opening while weakening the amount of light from the light emitting means so that the light can be directly viewed. Part and discharge from the opening
And a light emitting display unit which emits light to be, the light guide portion
The interval is gradually reduced toward the opening.
The light emitting window includes a light diffusing member . In the telephone according to the present invention, for example, when an incoming call from a telephone line is detected, the light emitting means provided on the telephone is turned on or off. Then, light from the light emitting means is guided to the light emitting window and the light emitting display. Here, an opening is provided in the light-emitting display portion where there is a possibility of direct viewing.
The light guide section is configured to gradually narrow toward the side.
Since the weakened light is guided, the amount of light radiated from the light-emitting display unit is set to an appropriate amount. It is possible to make it appropriate to a gentle degree. On the other hand, since the light emitted from the light emitting window can be viewed as indirect light, the light emitted from the light emitting window provided with the light diffusing member illuminates a wall or the like. Thus, even if the telephone is out of the field of view, the light emission is recognized in a wide area of the room. Further, since the light from the light emitting means can be viewed as indirect light, it is easy on the eyes. An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of a telephone. As shown in FIG. 1, on the right side of the telephone body 2 of the telephone 1, there is provided a first function setting section 10 which is operated when setting various functions added to the telephone 1. . The first function setting unit 10 includes a response setting button 1
1, confirmation setting button 12, mute setting display LED 13a,
Flash setting display LED 13b, priority call setting display L
ED 13c, answering mode setting button 14, auto dial setting button 15, stop / erase button 16, play button 17, and xenon tube 80 as a xenon discharge tube described later
A light-emitting display unit 18 that performs light display by light from the light source is provided. Below the first function setting section 10, there is provided a second function setting section 20 for performing volume adjustment and the like during monitor reproduction or the like. A dial button 30 is provided below the second function setting unit 20. Below the dial button 30, a third function setting unit 40 that is operated when setting redial, hold function, and the like is provided. On the left side of the telephone body 2, a handset mounting section 50 is provided.
Also, a speaker sound or monitor sound emission hole 51 is provided. On the back side of the telephone body 2, as shown in FIG.
A light emitting window 70 is provided as a light emitting port for performing light display with light from the xenon tube 80. FIGS. 3 to 5 show the main parts of the internal structure of the telephone body 2. FIG. As shown in these figures, a light guide section 81 having front and rear openings 82 and 83 is provided in the inner part of the inside of the telephone body 2. In the vicinity of the opening 83 side of the light guide 81, a xenon tube 80 as a light emitting means is provided. The light from the xenon tube 80 is guided to the openings 82 and 83 by the light guide 81, and
In addition, the light is emitted to the light emission window 70 side. Here, since the xenon tube 80 is located near the opening 83, it is located far from the opening 82, and as shown in FIG. The structure gradually narrows toward the opening 82 side. For this reason, although the light from the xenon tube 80 is relatively strong, the light is gradually weakened by internal reflection when guided inside the light guide portion 81 which gradually narrows toward the opening 82, so that the light from the light emitting display portion 18 The amount of emitted light is set to an appropriate amount, the brightness of the light-emitting display unit 18 is sufficient to be recognized even in bright daytime, and is appropriate to the extent that it is easy on the eyes. On the other hand, since the xenon tube 80 is located near the opening 83, the amount of attenuation of light from the xenon tube 80 is extremely small as compared with the opening 82, and almost the entire amount of light is guided. . Therefore, when the telephone body 2 is brought close to a wall or the like with the light emitting window 70 side as a back, the light emitting window 7
The light emitted from 0 is reflected on a wall or the like and can be viewed as indirect light. That is, light emitted from the xenon tube 80 is strong enough to be reflected on a wall or the like and visually recognized as indirect light. In addition, as shown in FIG. 7, the light emission window 70 is a diffusion lens that performs a diffusion operation in a vertical direction so that light can be effectively diffused. FIG. 6 shows a circuit configuration inside the telephone. As shown in the drawing, a bell signal from an office line is detected by a bell detecting circuit 92 and an incoming call from a door phone is detected by a door phone detecting circuit 98. When the control unit 93 recognizes any of these incoming calls, a bell generating circuit 94 is provided. Is generated, the bell signal is amplified to a predetermined level by the amplifier 95, and a bell sound is output from the speaker 96. At the same time, when the control unit 93 prompts the generation of the driving voltage from the light emitting circuit 97, the xenon tube 8
0 lights or blinks. Here, the lighting or blinking operation is
The setting is performed under the control of the control unit 93, and the setting can be changed by operating a setting button (not shown).
When the silent mode is set, the generation of the bell signal by the bell generation circuit 94 is stopped. When a handset (not shown) is lifted after the reception of the bell signal is detected, the communication control circuit 90
Is activated to form a communication circuit to receive a reception signal from the office line or door phone or to transmit a transmission signal to the office line or door phone. In the case where a handset is provided in the telephone body 2, even when an incoming extension bell is detected due to an outgoing call from the handset, a bell sound is output from the speaker 96 or light emitted by the xenon tube 80 is emitted. Output is performed. The telephone having the above configuration operates as follows. First, for example, when an incoming call that has occurred in an office line is detected, a bell sound is output from the speaker 96 based on the bell sound signal from the bell generating circuit 94, and the incoming call can be known by sound. At the same time, the xenon tube 80 is turned on or off based on the drive voltage from the light emitting circuit 97. Here, the light from the xenon tube 80 is guided toward the openings 82 and 83 of the light guide section 81. As described above, when the light is guided toward the opening 82, the xenon tube 80 is used.
Is gradually weakened by internal reflection in the light guide portion 81 gradually narrowing toward the opening portion 82, and the amount of light emitted from the light emitting display portion 18 becomes an appropriate amount. In other words, the light level of the light-emitting display unit 18 is sufficient to allow the light emission to be sufficiently recognized even when the surroundings of the telephone are bright during the daytime, and is appropriate so as to be easy on the eyes. On the other hand, the xenon tube 80 is located near the opening 83 side, and the attenuation of the light from the xenon tube 80 is extremely small as compared with the opening 82 side, and almost the entire light amount is guided. Since the light emitting window 70 is provided on the back side of the telephone main body 2, it is possible to capture light without directly looking at the relatively strong light of the light emitting window 70 and without irritating the eyes. The light emitting window 70 is formed of a transparent plastic, and its vertical cross section is formed in a laterally Fresnel lens shape as shown in FIG. It has the function of diffusing vertical light. Therefore, the telephone body 2 is connected to the light emitting window 7.
When approaching a wall or the like with the 0 side as a back, the light emitted from the light emitting window 70 and diffused is reflected on the wall or the like and can be viewed as indirect light, and also emitted from the light emitting window 70. Since light is reflected by walls, furniture, ceilings, and the like, an area where the light reaches is widened, and recognition of light emission is performed in a wide area in a room. As described above, in this embodiment, when an incoming call generated on a local line is detected, for example, a bell sound is output from the speaker 96 based on the bell sound signal from the bell generating circuit 94, and the incoming call is sounded. You can know. At the same time, the xenon tube 80 is turned on or off based on the drive voltage from the light emitting circuit 97, but the amount of light leaking from the light emitting display unit 18 is set to a degree that is easy on the eyes, and the light emitting window 70 is located on the telephone body 2 side.
Is provided on the rear side of the light emitting window 70, the relatively intense light of the light emitting window 70 is not directly seen, and the light can be captured without irritating the eyes. Moreover, when the telephone body 2 is placed near a wall or the like, the light from the light emitting window 70 can be viewed as indirect light from the wall or the like, and can be viewed as reflected light. Light from the light emitting means can be seen. Since the light emitted from the xenon tube is close to white light, the material of the emission window 70 can be colored to have a desired color. Further, the magnitude of the driving voltage from the light emitting circuit 97 or the capacity of the current that can be used for one discharge may be changed. In this case, the xenon tube 8 may be used.
Since the amount of light emitted from the light emitting display unit 18 and the light emitting window 70 is controlled by the change of the total light emission amount of 0, the desired light amount can be adjusted. In this embodiment, the case where the light emitting window 70 is provided on the back of the telephone has been described. Without having to do this, it is also possible to visually recognize the incoming call from a large part of the room as indirect light. That is, the light emitting window 70 as a light emitting port
Is not disposed at a position where the upper surface of the telephone main body 2 can be directly viewed like the front surface, but may be disposed at a position where indirect light can be maintained. In this embodiment, the telephone body 2
The case where the xenon tube 80 is incorporated in the telephone has been described. However, the present invention is not limited to this. As in the case of the second side, not only can the presence / absence of an incoming call be recognized by the bell sound output and the light output by the emission of the xenon tube 80, but also, for example, in the case of a handset in a fully charged state, the place to store the handset other than when charging is required. Since it is relatively free, the visibility can be improved, and the illumination position can be arbitrarily selected. As described above, according to the telephone of the present invention, for example, When the incoming call from the office line is detected, the light emitting means provided in the telephone lights or blinks. The light from the light emitting means is guided to the light emitting window and the light emitting display. Here, the light emitting display portion which may be directly viewed becomes gradually narrower toward the opening.
The light that is weakened by the light guide configured as described above is guided, so that the amount of light emitted from the light emitting display is set to an appropriate amount, and the light level of the light emitting display is sufficiently recognized even in bright daylight. It is possible to make the brightness as high as possible and appropriate to the eye. On the other hand, since the light emitted from the light emitting window can be viewed as indirect light, the light emitted from the light emitting window provided with the light diffusing member illuminates a wall or the like. Thus, even if the telephone is out of the field of view, the light emission is recognized in a wide area of the room even when the telephone is out of the field of view. Further, since the light from the light emitting means can be viewed as indirect light, the light is easy on the eyes.
