Communication device

【Technical field】

The present invention relates to a communication device including a handset, such as a telephone device and a facsimile device, and a device main body provided with a support base for supporting the handset, and capable of communicating with another communication device by the device main body.

[Background Art]

FIG. 8 is a cross-sectional view schematically illustrating the communication device 1 according to the related art. In FIG. 8, the thickness is omitted for easy understanding. For example, the communication device 1 such as a telephone device and a facsimile device is provided with a support base 4 for supporting the handset 3 on the device main body 2. The support base 4 has a first support portion 6 in which the receiving section 3a of the handset 3 fits and a first recess 5 that is opened only in the detaching direction Y of the handset 3 is formed. In addition, the support base 4 has a second support portion 8 in which the transmitting portion 3b of the handset 3 is fitted, and a second recess 7 that is opened only in the detachment direction Y of the handset 3 is formed.

When the handset 3 is supported by the support 4, the receiver 3 a fits into the first recess 5, and the transmitter 3 b fits in the second recess 7. At this time, the receiving section 3a of the handset 3 is supported by the first outer wall 9 facing the first recess 5 so as not to be displaced in the direction from the transmitting section 3 toward the receiving section 3a. In addition, the transmitting section 3b of the handset 3 is supported by the second outer wall 10 facing the second recess 7, so that the transmitting section 3b is prevented from being displaced in the direction from the receiving section 3a toward the transmitting section 3b. Is done. As a result, some external force acts on the communication device 1 and the handset 3 moves relative to the device body 2 in the direction from the receiver 3a to the transmitter 3b and the receiver 3b. Displacement in the direction toward the part 3 a is suppressed, and the handset 3 is prevented from falling off from the support 4.

Further, as another conventional technique, in a handset supported on a support base in the same manner as the communication device 1 described above, there is a telephone device in which a projection is provided in a transmitting section of the handset (for example, Japanese Utility Model Application Laid-Open No. 7-4414128). No. (see page 1, Figure 1). The telephone device In the above, when the handset is supported by the support base, the protrusion is brought into contact with the support base to bring the transmitting section and the support base into point contact, thereby reducing the frictional force between the transmission section and the support base. And make the handset slippery.

Communication devices such as telephone devices and facsimile devices are required to be miniaturized. However, if the distance between the receiver and transmitter of the handset is reduced, when the receiver is brought into contact with the user's ear, the transmitter cannot be placed near the mouth of the user and the user utters. It is difficult to transmit the voice to the transmitter. Therefore, in order to downsize the communication device, it is necessary to downsize the device body. In order to efficiently reduce the size of the device body 2 of the communication device 1 as shown in FIG. 8, in the device body 2, one side 11 of the body including the first outer wall 9 of the support 4, and the support 4 The other main body including the second outer wall 10 and the other side 12 can be eliminated. As a result, the apparatus main body 2 is arranged such that one side wall of the support 4 on the first support portion 6 side is disposed at a position indicated by the two-dot chain line L 1, and that the support 4 is on the second support portion 8 side. The other side wall is arranged at the position indicated by the other two-dot chain line L2. As described above, the size of the apparatus main body 2 in the direction from the first support portion 6 of the support base 4 to the second support portion 8 is extremely small, and the device main body 2 is miniaturized.

FIG. 9 is a cross-sectional view schematically showing a communication device 1A including a miniaturized device main body 2A. In FIG. 9, the thickness is omitted for easy understanding. In the communication device 1A, the first recess 5A of the first support portion 6A into which the receiver 3a of the handset 3 fits is provided in one opening direction Z1 substantially perpendicular to the mounting / dismounting direction Y of the receiver 3a. Open to the public. In the communication device 1 shown in FIG. 8, the receiving section 3 a fitted into the first recess 5 of the handset 3 by the first outer wall 9 of the support 4 is directed from the transmitting section 3 b to the receiving section 3 a. Such displacement is suppressed and supported. However, the communication device 1A shown in FIG. 9 does not have the first outer wall 9 as shown in FIG. 8, and the first recess 5A is substantially perpendicular to the mounting / dismounting direction Y of the receiver 3a. The receiving part 3a fitted in the first recess 5A is opened from the transmitting part 3b substantially parallel to the opening direction one direction Z1. It can be displaced in the direction toward a. As a result, when some external force acts on the communication device 1A, the handset 3 moves relative to the device body 2A as shown by the two-dot chain line L3 in FIG. From 3 b to earpiece 3 a There is a risk that the handset 3 will fall off from the support 4A due to the displacement in the opposite direction.

In the communication device 1A, the second concave portion 7A of the second support portion 8A into which the transmitting portion 3b of the handset 3 fits is provided in the opening direction substantially perpendicular to the mounting / dismounting direction Y of the transmitting portion 3b. Open in direction Z2. In the communication device 1 shown in FIG. 8, the transmitting section 3 b that fits into the second recess 7 of the handset 3 by the second outer wall 10 of the support base 4 is connected to the receiving section 3 a to the transmitting section 3. Displacement in the direction toward b is suppressed and supported. However, the communication device 1A shown in FIG. 9 does not include the second outer wall 10 as shown in FIG. 8, and the second recess 7A is substantially perpendicular to the mounting / dismounting direction Y of the transmitting section 3b. The mouthpiece 3b fitted in the second recess 7A is opened from the earpiece 3a, which is substantially parallel to the opening direction other direction Z2. It becomes displaceable in the direction toward 3b. As a result, when some external force acts on the communication device 1A, the handset 3 moves relative to the device main body 2A as shown in the other two-dot chain line L4 in FIG. There is a risk that the handset 3 may be displaced from 3a toward the transmitting section 3b and drop off from the support 4A.

In addition, when the communication device 1A shown in FIG. 9 is provided with a projection on the transmission unit 3b of the handset 3 as in the other conventional technology, the friction between the transmission unit 3b and the second support 8A is increased. The power is reduced. As a result, when some external force acts on the communication device 1A, the handset 3 is displaced relative to the device body 2A in the direction from the receiver 3a to the transmitter 3b. Promote it.

As described above, the hook switch is mounted on the apparatus main body so as to be able to protrude and retract from the fitting recess. When the operation piece of the hook switch is immersed, it is detected that the handset is in the on-hook state mounted on the support base. When the operation piece of the hook switch protrudes into the fitting recess, it is detected that the handset is in the off-hook state in which the handset is not mounted on the support base. The operation piece of the hook switch is arranged between the side wall and the projection piece, and is formed such that the end near the projection piece is inclined upward as it moves away from the projection piece. When some external force is applied to the handset, the earpiece is displaced in the direction from the side wall toward the protrusion, and the operation piece is released from the pressing by the earpiece and protrudes into the fitting recess. When trying to return to the position that was placed before the displacement, the receiving part displaced in the direction from the protruding piece toward the side wall contacts the end of the operating piece near the protruding piece. It can be easily immersed by being pressed by the part. Thus, it is possible to prevent the operation piece from preventing the displacement of the earpiece from the projection piece toward the side wall. [Brief description of the drawings]

The central part 60 between the receiving support part 51 and the transmitting support part 52 of the supporting base 50 is the receiving side wall 54 of the receiving supporting part 51 and the transmitting bottom wall of the transmitting supporting part 52. It is formed so as to be on the upstream side in the departure direction A1 from the part near the reception support part 51 of 59. Therefore, when the handset 30 is supported by the support base 50, as shown in FIG. 2, the gripping part 33 of the handset 30 and the central part 60 of the support base 50 are separated from each other. I have. As described above, the space 61 that opens in the width direction of the handset 30 is formed while facing the grip portion 33 of the handset 30 and the central portion 60 of the support body 50. Thus, the user can easily insert his / her finger into the space 61 and hold the handset 30.

When the device main body 21 is placed on a horizontal plane, the handset 30 is a virtual plane connecting the receiver 31 and the transmitter 32, indicated by a two-point line L 10 in FIG. The L 10 force is tilted with respect to the horizontal plane H indicated by the one-dot chain line H, and is supported by the support base 50 so that the reception section 31 is arranged above the transmission section 32. In the present embodiment, the angle 01 formed between the virtual plane L10 and the horizontal plane H may be within an angle range of, for example, 10 degrees or more and 40 degrees or less.

FIG. 6 is a cross-sectional view showing the handset 30 arranged at a displacement position P1 displaced from the support position P0 in the earpiece release direction B1. In FIG. 6, the thickness is omitted for easy understanding. When the user supports the handset 30 on the support base 50, the handset 30 may be erroneously placed at the displacement position P1 displaced from the support position P0 in the earpiece opening direction B1. Also, for example, when an external force acts on the communication device 20 in the direction B1 due to a user accidentally colliding with the communication device 20, the handset 30 is displaced in the direction B1. As a result, there is a possibility of displacement from the support position P0 in the earpiece release direction B1.

Even if this should happen, the receiver 31 of the handset 30 will be moved by the protrusion 56 of the receiver support 51 1 to the receiver 31 of the handset 30

Displacement in the earpiece opening direction B1 is suppressed more than in the case of 56, and it is possible to prevent detachment from the earpiece support portion 51. In addition, even if the receiving support 51 gets on the slope 56 a of the projection 51, the slope 5 of the projection 56 of the reception support 51 will not work.

6a is formed so as to be inclined downward toward the receiving side wall 54, so that the receiving part 31 of the handset 30 is guided by the inclined part 56a of the protruding piece 56 and own weight. With this, the receiver can be easily displaced to the upstream side in the direction B1.

In addition, the receiving bottom wall 55 of the receiving support unit 51 and the transmitting bottom wall 59 of the transmitting support unit 52 are inclined downward in the reverse direction of the receiving opening direction B1. Further, in a state where the handset 30 is supported by the support base 50 at a position deviated from the supporting position, the transmitting section 32 and the transmitting bottom wall 59 are moved by the transmitting section 32 to the transmitting supporting section 52. It is formed so as to make a line contact or a point contact with the transmission bottom wall 59. As a result, the frictional force between the transmitting section 32 and the transmitting bottom wall 59 becomes extremely small, and the handset 30 is under its own weight, and is easily displaced in the receiving and releasing direction B 1 in the opposite direction to support. It is possible to return to position P0.

When the receiver 31 of the handset 30 is disposed at the displacement position P1 such that the receiver 31 abuts on the projection 56 of the receiver support 51, the operation piece 70 is pressed by the receiver 31. Not protruding into the receiving fitting recess 53. When the handset 31 placed in the displacement position P1 attempts to return to the support position P0 and the receiver 31 is displaced in the opposite direction B1 and the receiver is displaced in the opposite direction, the receiver 31 becomes It abuts on the end 72. As shown in FIG. 5, the distal end portion 7 2 a of the operation piece 70 on the other end portion 72 of the projection piece 56 on the side thereof is inclined upward as it moves away from the projection piece 56 as shown in FIG. 1 is displaced in the opposite direction while the abutment opening direction B 1 is in contact with the front end portion 7 2a, whereby the other end portion 72 of the operation piece 70 is easily pressed downward by the reception portion 31. The operation is immersed in the immersion direction C2 around one axis L70, and is immersed in the immersion direction C2, and is arranged at the on-hook position D1. This prevents the operation piece 70 from preventing the displacement from the projection piece 56 of the receiving section 31 toward the receiving side wall 54, in other words, the displacement in the opposite direction of the receiving opening B1. be able to.

In the operation piece 70, a portion that is inclined upward as it moves away from the projection piece 56, that is, the tip portion 72a of the other end portion 72 is located at a position farthest from the angular displacement axis L70. . As a result, only a small downward force is applied to the tip portion 72 a of the other end portion 72 of the operation piece 70, and the operation piece 70 is immersed in the direction C 2 around the angular displacement axis L 70. The required torque for angular displacement can be obtained. Therefore, the angular displacement in the immersion direction C2 can be made extremely easily when the handset 70 comes into contact with the other end 72 of the receiving piece 31 of the handpiece 70.

The distance between the receiving side wall 54 of the receiving support part 51 of the support base 50 and the protruding piece 56 is such that the handset 30 is disposed at the displacement position P1 and the transmitting part 3 2 of the handset 30 However, it is desirable that the dimensions be set so as not to separate from the transmission bottom wall 59 of the transmission support portion 51 of the support base 50.

As described above, according to the communication device 20 of the present embodiment, even if any external force acts on the handset 30 at least in the receiving-opening direction B1 and the receiving-opening direction B1, the receiving unit It is possible to prevent as much as possible that the part 31 is separated from the receiving support part 51 of the support base 50. Further, even if the handset 30 is displaced from the support position P 0 in the support part 50 in the earpiece release direction B 1, the handset 30 can easily return to the support position P 0. Further, according to the communication device 20 of the present embodiment, the receiving side wall 54 is configured such that the handset 30 is supported by the support base 50 at the supporting position, and the receiving unit 31 and the holding unit of the handset 30 are held. 33, it is inclined so as to come into contact with the above-mentioned part and comes into contact with the above-mentioned part. It is formed so as to be nearly perpendicular to the surface. As a result, it is possible to prevent the receiving section 31 from being displaced in the opposite direction of the receiving opening direction B1 as much as possible.

Further, according to the communication device 20 of the present embodiment, the receiving side wall 54 is formed so as to have at least a predetermined thickness in the receiving opening direction B1, so that the user erroneously releases the handset 30. The receiver 31 of the handset 30 can abut the receiver side wall 54 even when the receiver is placed at a position slightly offset from the support position of the support base 50 in the direction of the earpiece opening direction B1 opposite side. . As a result, the receiving section 31 of the handset 30 is guided by the receiving side wall 54 toward the receiving bottom wall 55, and is fitted into the receiving fitting recess 53, so that the support table 50 is supported at the supporting position. It is surely supported.

Further, the support table 50 of the communication device 20 of the present embodiment supports the handset 3 as in the conventional support table 4 as shown in FIG. Since the first and second side walls 9 and 10 are not provided so as to be larger than the longitudinal dimension of the handset 3, the support table 50 supports the handset 30 while supporting the handset 30. Therefore, the size in the longitudinal direction can be made smaller than that in the longitudinal direction. This facilitates miniaturization of the device main body 21 of the communication device 20.

In the communication device 20 of the present embodiment, the inclined portion 57 of the projection 56 of the receiving support portion 51 is formed to have a partially spherical shape, but is not limited thereto. The inclined portion 57 of the protruding piece 56 only needs to be inclined downward toward the receiving side wall 54, and may be formed in a planar shape.
