Description

Electronic device and camera

Technical Field

The invention relates to an electronic device and a photographic device.

Background

A network Camera (IP Camera) generally includes a Camera module, an image compression module, a network communication module, and a processor. With the rapid development of the internet of things, the demand and application of the network camera are more and more extensive, for example: searching and recording images of human things in a certain range, transmitting the searched and recorded image data to a remote server through a network, and displaying the image data on a mobile communication device of a third party.

In addition, the demand of people for safe life is gradually increased, and in the family life, the network camera can be set to start the shooting function when no one is at home, and the shooting function of the network camera is turned off when a user is at home. Generally, the above-described photographing function can be turned off by blocking software or hardware that turns off the network or is not connected to the network. However, there is a risk that the network camera is hacked, because the camera lens is directed to people within a certain range, once the camera function of the camera lens is restarted, people within the range, including the privacy of the user, may be peeped at any time, and therefore, the above-mentioned blocking method by software and hardware cannot effectively ensure the privacy protection performance of the network camera.

Therefore, manufacturers have developed a privacy mode (privacy mode) function of the network camera, and have formed the privacy mode by retracting the camera lens from the outside of the camera body into the camera body through the transmission mechanism. By means of the way of shielding the camera lens physically, even if the network camera is hacker and the camera function of the camera lens is restarted, peeking cannot be performed.

However, when the camera lens is located outside the camera body (i.e. the network camera is in the on mode), or the camera lens is in the moving process of ascending and descending, if the camera lens is suddenly pushed to the camera body by an external force, the external force may be linked to the transmission mechanism, so that the external force is transmitted by the camera lens and applied to the moving member and the moved member which are matched and contacted with each other in the transmission mechanism, thereby causing damage to the moving member or/and the moved member, and further causing a failure of the mechanism for switching the privacy mode. Therefore, how to improve the above-mentioned problems is one of the issues to be solved in the industry.

Fig. 1 is a schematic diagram of an electronic device according to an embodiment of the invention. Referring to fig. 1, an electronic device 100 of the present embodiment includes: the main body 110, the functional device 120, the power transmission structure 130, and the retreating structure 140, wherein the functional device 120 is movable relative to the main body 110, and the power transmission structure 130, the retreating structure 140, and a part of the elements of the functional device 120 are disposed in the main body 110, for convenience of description, elements such as the power transmission structure 130 and the retreating structure 140 are shown in a part of the main body 110 in fig. 1.

In the present embodiment, the power transmission structure 130 includes a driving device 132 and a transmission device composed of a gear 134 and racks 136, in other words, the electronic device 100 of the present embodiment uses the gear 134 and the racks 136 as the transmission device of the mobile function device 120. The functional device 120 includes a moving body 122 and a linking member 126, and the moving body 122 can be configured with corresponding functional elements (such as a camera module, a detection module, etc.). One end of the linkage member 126 is connected to the moving body 122, and the other end of the linkage member 126 is connected to the driving device 132, so that the driving device 132 can link the functional device 120. It should be noted that the linking member 126 is exemplified by a link, but the invention is not limited thereto.

In the present embodiment, the driving device 132 is connected to the gear 134, and the gear 134 has a plurality of teeth 134A, the rack 136 has a plurality of teeth 136A along the moving direction L, and the teeth 134A of the gear 134 engage with the corresponding teeth 136A of the rack 136. The driving device 132 is, for example, a motor, and drives the gear 134 to rotate, so that the teeth 134A of the gear 134 engage with the corresponding teeth 136A of the rack 136 in the moving direction L to drive the functional device 120 to move along the moving direction L, in other words, the driving device 132 converts the rotational motion into the linear motion through the design of the gear 134 and the rack 136, so as to achieve the purpose of ascending and descending (in the embodiment, the moving direction L) the functional device 120.

Fig. 2 is a schematic view of the gear 134 and the rack 136 of fig. 1 according to the present invention. Referring to fig. 1 and 2, in the mechanical design of the power transmission structure 130, due to the design of the pressure angle a between the gear 134 and the rack 136, the gear 134 transmits force to the rack 136 along the direction of the pressure angle a, and the pitch diameter (or reference diameter) of the gear 134 is 2 times of the gear radius R1, at this time, the rack 136 can be applied with an external force F1 to lean against the gear 134, and the external force F1 causes the rack 136 to engage with the gear 134. Generally, the external force F1 is sufficient to fix the rack 136 to resist the component of the gravity W1 of the functional device 120 and the component of the torsion M of the driving device 132 applied to the rack 136, while the component of the gravity W1 in the direction of the pressure angle a can be represented as W2, the component of the torsion M in the direction of the pressure angle a can be represented as F3, and the component of the external force F1 of the rack 136 in the direction of the pressure angle a can be represented as F4, and W2, F3, and F4 can be calculated by the following equations (1) to (3), respectively:

W2＝W1×cosA (1)；

F3＝M/R1 (2)；

F4＝F1×sinA (3)。

when the driving device 132 drives the functional device 120 to move along the moving direction L, the sum of the component force W2 of the gravity W1 in the direction of the pressure angle a and the component force F3 of the torsion M in the direction of the pressure angle a is equal to the component force F4 of the external force F1 of the rack 136 in the direction of the pressure angle a, as shown in the following formula (4):

W2+F3＝F4 (4)。

thus, the rack 136 is stationary and non-displaced.

Combining the above equations (1) to (4), the minimum external force F1 of the rack 136 should be designed as the following equation (5):

F1＝(W1×cosA+M/R1)/sinA (5)。

as shown in fig. 1, the electronic device 100 includes a retreating structure 140, the retreating structure 140 may include a holding device 142, the holding device 142 is connected to the rack 136, the rack 136 is located between the holding device 142 and the gear 134, wherein the holding device 142 is further configured to provide the external force F1 to the rack 136, so that the rack 136 is normally engaged with the gear 134. The configuration of the holding device 142 is not limited, for example, the spring 242A of fig. 3, the rubber block 342A of fig. 4, the first magnetic element 442A and the second magnetic element 442B of fig. 5, or the first elastic arm 542A and the second elastic arm 542B of fig. 6, and the configuration of the holding device 142 can be adjusted according to the actual product.

In the case that the driving device 132 drives the functional device 120 to move along the moving direction L, if the functional device 120 suddenly receives a pushing force F2 to push the body 110, so that the gear 134 receives an additional pushing force F2, a component F5 of the pushing force F2 in the direction of the pressure angle a is expressed by the following formula (6):

F5＝F2×cosA (6)。

when the functional device 120 is subjected to the pushing force F2 during the movement along the moving direction L, the engagement between the gear 134 and the rack 136 may be poor, the gear 134 or the rack 136 may be broken, or the driving device 132 may be damaged. Therefore, in the present embodiment, the retreating structure 140 further separates the rack 136 from the gear 134, and the rack 136 is moved to avoid stress concentration between the gear 134 and the rack 136.

As can be seen from the above equation (4), when the resultant force of the gear 134 in the direction of the pressure angle a increases by the component force F5 of the pushing force F2 in the direction of the pressure angle a, the resultant force of the gear 134 in the direction of the pressure angle a is larger than the component force F4 of the external force F1 of the rack 136 in the direction of the pressure angle a, and at this time, the force between the gear 134 and the rack 136 is larger than the force applied to the rack 136 (the component force F4 of the external force F1 in the direction of the pressure angle a), and the rack 136 moves in the opposite direction or the direction different from the external force F1 by the retreating structure 140. That is, when the gear 134 receives the pushing force F2, the rack 136 receives a force larger than the component force F4 of the external force F1 applied to the rack 136, so that the rack 136 cannot be pushed by the external force F1 to lean against the gear 134. When the driving device 132 drives the functional device 120 to move along the moving direction L, the force is the sum of the component force applied to the rack 136 by the pushing force F2, the component force applied to the rack 136 by the gravity W1 of the functional device 120, and the component force applied to the rack 136 by the torsion M of the driving device 132, that is, the sum of the component force F5 of the pushing force F2 in the pressure angle a direction, the component force W2 of the gravity W1 in the pressure angle a direction, and the component force F3 of the torsion M in the pressure angle a direction is greater than the component force F4 of the external force F1 in the pressure angle a direction, the rack 136 is pushed by the gear 134, the holding device 142 in the retreating structure 140 is used to provide an evading stroke for the rack 136, and the direction LB of the evading stroke is different from the moving direction L, and the direction LB of the evading stroke is the direction of the rack 136 away from the gear 134. In other words, when the gear 134 receives the pushing force F2 greater than a predetermined value, the rack 136 is pushed by the gear 134, and the rack 136 is linked with the holding device 142, so that the rack 136 moves according to the above-mentioned avoiding stroke. The predetermined value can be calculated from the external force F1, the gravity W1 and the torsion M, and can be, for example, the sum of the component F4 of the external force F1 in the direction of the pressure angle a minus the component W2 of the gravity W1 in the direction of the pressure angle a and the component F3 of the torsion M in the direction of the pressure angle a. Therefore, the rack 136 is separated from the gear 134, the rack 136 is moved to prevent stress from concentrating between the gear 134 and the rack 136, and when the rack 136 moves to be out of contact with the gear 134, the functional device 120 can move in the moving direction L and be accommodated in the machine body 110, and the gear 134 and the rack 136 are prevented from being damaged by the pushing force F2. In other words, when the pinion 134 receives the thrust force F2 greater than the predetermined value T, the rack 136 is pushed by the pinion 134. The predetermined value T may be obtained by calculation from the external force F1, the gravity W1, and the torsion M, and for example, the predetermined value T may be obtained by the following equation (7):

T＝(F4-W2-F3)/cosA (7)。

on the other hand, when the functional device 120 is located outside the body 110 of the electronic device 100 and the driving device 132 does not drive the functional device 120 to move along the moving direction L (i.e. the driving device 132 is not actuated, and the torque M of the driving device 132 is 0), when the functional device 120 is pushed toward the body 110 by the pushing force F2, the gear 134 is also pushed by the pushing force F2, and the rack 136 is pushed by the gear 134. When the force is the sum of the component force applied to the rack 136 by the pushing force F2 and the component force applied to the rack 136 by the gravity W1 of the functional device 120, that is, the sum of the component force F5 of the pushing force F2 in the direction of the pressure angle a and the component force W2 of the gravity W1 in the direction of the pressure angle a, the force is greater than the component force F4 of the external force F1, and the rack 136 is pushed by the gear 134. In other words, when the pinion 134 receives the thrust force F2 greater than the predetermined value T, the rack 136 is pushed by the pinion 134. The predetermined value T may be calculated from the external force F1 and the gravity W1, and may be obtained by the following equation (8):

T＝(F4-W2)/cosA (8)。

in addition, the retreating structure 140 may further include a fixing member for limiting the direction LB of the retreating stroke of the rack 136, and the form of the holding device and the fixing member is illustrated in fig. 3 to 9, but the invention is not limited thereto.

Fig. 3 is a schematic diagram of an electronic device according to another embodiment of the invention. Referring to fig. 2 and fig. 3, in the present embodiment, the power transmission mechanism 130, the retraction structure 240, and some components of the functional device 120 are disposed in the accommodating space 112 of the body 110, and for convenience of description, components such as the power transmission mechanism 130 and the retraction structure 240 are shown in part of the body 110 in fig. 3. The electronic device 200 of fig. 3 differs from the electronic device 100 of fig. 1 at least in that: the retreating structure 240 may include a holding device 242 and a fixing member 244, the rack 136 is connected to the holding device 242, the holding device 242 is connected to the fixing member 244, and the holding device 242 and the rack 136 are mutually linked and can move relative to the fixing member 244. The holding device 242 includes an elastic element, which has at least one spring 242A of the present embodiment or a rubber block 342A shown in fig. 4, but the implementation of the elastic element is not limited thereto. First, taking the spring 242A of the present embodiment as an example, the rack 136 is located between the spring 242A and the gear 134, and the spring 242A is connected between the rack 136 and the fixing member 244.

In this configuration, the spring 242A is coupled to the rack 136, and the spring 242A is configured to provide an external force (e.g., an external force F1 in fig. 2) such as a pushing force provided by the spring 242A to urge the rack 136 against the gear 134 such that the teeth 136A of the rack 136 engage the teeth 134A of the gear 134. When the gear 134 is applied with a pushing force F2, the sum of the component of the pushing force F2 applied to the rack 136 (i.e., the component F5 of the pushing force F2 in the direction of the pressure angle a), the component of the gravity W1 of the functional device 120 applied to the rack 136 (i.e., the component W2 of the gravity W1 in the direction of the pressure angle a) and the component of the torsion M of the driving device 132 applied to the rack 136 (i.e., the component F3 of the torsion M in the direction of the pressure angle a) is greater than the spring force component of the spring 242A (e.g., the component F4 of the external force F1 in fig. 2), the rack 136 is pushed by the gear 134, the rack 136 moves in the direction opposite to the external force F1 (i.e., the direction LB of the evading stroke), and the rack 136 interlocks the spring 242A, and the rack 136 compresses the rack 136 and can move in the direction LB of the evading stroke. The rack 136 is retracted in the direction LB away from the stroke, so that no stress is generated between the rack 136 and the gear 134, and damage to the gear 134 and the rack 136 due to the thrust F2 is avoided.

In one embodiment, during the process of releasing the rack 136, the rack 136 can move toward the fixing member 244, and the fixing member 244 is used to limit the avoiding stroke direction LB. Specifically, the fixing member 244 includes a first plate 244A, a second plate 244B, and a third plate 244C. The two ends of the first plate 244A are respectively connected to the second plate 244B and the third plate 244C, the second plate 244B and the third plate 244C are opposite to each other, and a space formed among the first plate 244A, the second plate 244B and the third plate 244C can accommodate the rack 136. The inner surface B20 of the second plate 244B is parallel to the outer side surface B40 of the rack 136, and the inner surface B30 of the third plate 244C is parallel to the outer side surface B50 of the rack 136. One end of the spring 242A is attached to the bottom surface B60 of the rack 136 and the other end of the spring 242A is attached to the inner surface B10 of the first plate 244A. The rack 136 and the first plate 244A of the present embodiment form an avoiding stroke therebetween, and the direction LB of the avoiding stroke refers to a direction in which the rack 136 moves toward the inner surface B10 of the first plate 244A.

The above description is given by way of example of the case where the functional device 120 is affected by the pushing force F2 while moving in the moving direction L. It should be noted that, in an embodiment, when the functional device 120 (e.g., the camera module 124 in the functional device 120 of fig. 11) does not move outside the body 110, the torque M of the driving device 132 is 0, and the force applied to the rack 136 in the above equation (4) may be the following equation (9):

W2＜F4 (9)。

therefore, unless the external force F1 pushes the rack 136 and moves toward the gear 134 at the moment when the external force F2 is affected by the additional pushing force F2 and the sum of the component F5 of the pushing force F2 in the direction of the pressure angle a and the component W2 of the gravity W1 in the direction of the pressure angle a is greater than the component F4 of the external force F1, the rack 136 is pushed by the gear 134 and moves toward the direction opposite to or different from the external force F1. In an embodiment, corresponding stopping structures or limiting structures (not shown) may be disposed on the outer side surface B40 of the rack 136 and the inner surface B20 of the corresponding fixing member 244 thereof, and the outer side surface B50 of the rack 136 and the inner surface B30 of the corresponding fixing member 244 thereof, so that the rack 136 is not pushed out of the fixing member 244 by the external force F1 (as shown in the direction opposite to the direction LB of the escape stroke in fig. 3), in other words, the fixing member 244 of the present invention may limit the moving range of the rack 136.

Fig. 4 is a schematic diagram of an electronic device according to another embodiment of the invention. Referring to fig. 2 and fig. 4, in the present embodiment, the power transmission mechanism 130, the retraction structure 340, and a part of the functional device 120 are disposed in the accommodating space 112 of the machine body 110, and for convenience of description, fig. 4 shows the power transmission mechanism 130, the retraction structure 340, and other elements in a part of the machine body 110. The electronic device 300 of fig. 4 differs from the electronic device 100 of fig. 1 at least in that: the retreating structure 340 may comprise a holding device 342 and a fixing member 244, wherein the holding device 342 comprises a rubber block 342A. Therefore, the difference between the present embodiment and the aforementioned fig. 3 is at least: the elastic element is a rubber block 342A, and the rubber block 342A can achieve the effect similar to the spring 242A of fig. 3. In one embodiment, the rubber block 342A is made of rubber. Specifically, one side of the rubber block 342A abuts against the bottom surface B60 of the rack 136, and the other side of the rubber block 342A abuts against the inner surface B10 of the first plate 244A. The rubber block 342A is disposed between the rack 136 and the first plate 244A, the rubber block 342A is disposed in a space formed by the first plate 244A, the second plate 244B and the third plate 244C of the fixing member 244, when the rubber block 342A is pressed to deform, the rack 136 can move toward the inner surface B10 of the first plate 244A, that is, the rack 136 moves along the direction LB avoiding the stroke.

When the pushing force F2 is applied to the gear 134, the elastic member (e.g., the spring 242A, the rubber piece 342A described above) is compressed or urged by the rack 136 to be deformed, and accumulates restoring force. When the pushing force F2 is no longer applied to the gear 134, the elastic member (e.g., the spring 242A, the rubber block 342A described above) compressed or pushed by the rack 136 and deformed may push the rack 136 toward the gear 134 by the accumulated restoring force, and the rack 136 is engaged with the gear 134 again. The above-mentioned corresponding blocking structure or position-limiting structure disposed on the outer side surface B40 of the rack 136 and the inner surface B20 of the corresponding fixing member 244, and the outer side surface B50 of the rack 136 and the inner surface B30 of the corresponding fixing member 244 can further prevent the rack 136 from being pushed out of the space formed by the first plate 244A, the second plate 244B and the third plate 244C due to the restoring force.

Fig. 5 is a schematic diagram of an electronic device according to still another embodiment of the invention. Referring to fig. 2 and fig. 5, in the present embodiment, the power transmission mechanism 130, the retraction structure 440, and some components of the functional device 120 are disposed in the accommodating space 112 of the body 110, and for convenience of description, in fig. 5, some components such as the power transmission mechanism 130 and the retraction structure 440 are shown in some of the body 110. The electronic device 400 of fig. 5 differs from the electronic device 100 of fig. 1 at least in that: the retreating structure 440 may include a holding device 442 and a fixing member 244, wherein the holding device 442 includes a first magnetic element 442A and a second magnetic element 442B. In the present embodiment, the first magnetic element 442A is disposed inside the rack 136, the second magnetic element 442B is disposed inside the first plate 244A, and the second magnetic element 442B is disposed opposite to the first magnetic element 442A, such that an avoiding stroke is formed between the bottom surface B60 of the rack 136 and the inner surface B10 of the first plate 244A. Here, the first magnetic element 442A is disposed inside the rack 136, but not limited to this, the first magnetic element 442A may also be disposed on the bottom surface B60 of the rack 136. The second magnetic element 442B is disposed in the first plate 244A of the fixing member 244, but not limited thereto, the second magnetic element 442B may also be disposed on the inner surface B10 of the first plate 244A. The magnetic force of the first magnetic element 442A and the magnetic force of the second magnetic element 442B repel each other. Under this configuration, the first magnetic element 442A and the second magnetic element 442B magnetically repel each other to provide an external force (e.g., the external force F1 shown in fig. 2) to urge the rack 136 against the gear 134, such that the teeth 136A of the rack 136 engage the teeth 134A of the gear 134. When the gear 134 is applied with the pushing force F2, if the rack 136 is subjected to a force (which includes at least the sum of the component of the pushing force F2 applied to the rack 136 and the component of the external force applied to the rack 136 by the gravity W1 of the functional device 120) that is greater than the component F4 (which is provided by the first magnetic element 442A and the second magnetic element 442B with the repulsive force) applied to the rack 136 by the external force F1 (the component of the external force includes the sum of the component of the pushing force F2 applied to the rack 136 and the component of the external force applied to the rack 136 by the second magnetic element 442B), the rack 136 is pushed by the gear 134 to move toward the inner surface B10 of the first plate 244A, and the rack 136 moves along the retreating direction LB, so that the rack 136 does not contact the gear 134, and the damage between the gear 134 and the rack 136 due to the pushing force F2 is avoided.

Fig. 6 is a schematic diagram of an electronic device according to another embodiment of the invention. Referring to fig. 2 and fig. 6, in the present embodiment, the power transmission structure 530, the retreating structure 540 and elements of part of the functional device 120 are disposed in the accommodating space 112 of the machine body 110, and for convenience of description, elements such as the power transmission structure 530 and the retreating structure 540 are shown in fig. 6 for part of the machine body 110. The electronic device 500 of fig. 6 differs from the electronic device 100 of fig. 1 at least in that: the retreating structure 540 may include a holding device 542 and a fixing member 244, the holding device 542 includes a plurality of elastic arms, such as a first elastic arm 542A and a second elastic arm 542B, the first elastic arm 542A and the second elastic arm 542B and the rack 536 in the power transmission structure 530 form a deformed rack, the first elastic arm 542A and the second elastic arm 542B are respectively and correspondingly connected between the rack 536 and the fixing member 244, wherein the deformed rack may be integrally formed. In other embodiments, the deformation rack may be connected by the rack 536 to the corresponding first and second

resilient arms

542A and 542B. Specifically, the space formed between the first plate 244A, the second plate 244B, and the third plate 244C can accommodate the rack 536. The rack 536 includes a bottom surface B63 and corresponding first and second outer side surfaces B43 and B53. The first spring arm 542A is connected to the inner surface B20 of the corresponding second plate 244B and the first outer side B43 of the rack 536, and the second spring arm 542B is connected to the inner surface B30 of the corresponding third plate 244C and the second outer side B53 of the rack 536. On the other hand, the bottom surface B63 of the rack 536 faces the inner surface B10 of the first plate 244A, i.e., the bottom surface B63 of the rack 536 of the present embodiment forms an escape stroke with the inner surface B10 of the first plate 244A. When the rack 536 moves toward the first plate 244A, i.e., the rack 536 moves along the avoiding stroke direction LB, the fixing member 244 is configured to limit the avoiding stroke direction LB.

Under this configuration, the deformed rack constituted by the first elastic arm 542A, the second elastic arm 542B and the rack 536 is linked between the gear 134 and the fixing member 244, and the first elastic arm 542A and the second elastic arm 542B are used to provide an elastic force (as shown by the external force F1 in fig. 2) to make the rack 536 approach the gear 134, so that the tooth 536A of the rack 536 is engaged with the tooth 134A of the gear 134. When the gear 134 is applied with the pushing force F2, if the rack 136 receives a force (such as a force including at least a sum of a component force applied to the rack 136 by the pushing force F2 and a component force applied to the rack 136 by the gravity W1 of the functional device 120) larger than a component force F4 (herein, a component force of an elastic force of the first elastic arm 542A and the second elastic arm 542B) applied to the rack 136 by the external force F1, the rack 536 is pushed by the gear 134, that is, the deformation of the first elastic arm 542A and the second elastic arm 542B can realize a moving stroke of the rack 536 along the avoiding stroke direction LB, and the rack 536 moves along the avoiding stroke direction LB, so that the rack 536 does not contact the gear 134, and the damage between the gear 134 and the rack 536 due to the pushing force F2 is avoided. Specifically, the first elastic arm 542A and the second elastic arm 542B may be formed by connecting a plurality of elongated cantilever structures in series, and the required external force F1 can be realized by the geometric design and number of the cantilever structures, and the amount of deformation of the cantilever structures can realize the moving stroke of the rack 536 along the direction LB of the evasive stroke. The present invention is not limited to the number of cantilevers, but a sufficient number of cantilevers is more likely to disperse the stress generated in the cantilever structure due to the deformation of the material of the cantilever, so that the stress does not exceed the yield strength of the material, and still maintains the behavior of plastic deformation possessed by the cantilever.

It should be noted that the above-mentioned fig. 2 to 6 can be used to limit the direction LB of the avoiding stroke by the fixing member, and the following is exemplified by fig. 7 to 9.

In addition, the shape of the fixing member 244 may also limit an angle formed between the direction LB of the escape stroke of the rack 136 and a reference direction (e.g., the moving direction L). As shown in fig. 7, the inner surface B20 of the second plate 244B and the inner surface B30 of the third plate 244C in the fixing member 244 are parallel to each other, the inner surface B20 of the second plate 244B and the outer side surface B40 of the rack 136 are parallel to each other, and the inner surface B30 of the third plate 244C and the outer side surface B50 of the rack 136 are parallel to each other, that is, the outer side surface B40 and the outer side surface B50 of the rack 136 respectively move along the inner surface B20 of the second plate 244B and the inner surface B30 of the third plate 244C, that is, an angle formed between the stroke avoiding direction LB and the moving direction L is related to the configuration and the configuration of the inner surface B20 of the second plate 244B and the inner surface B30 of the third plate 244C.

The shape of the rack 736 in the power transmission structure 730 can be adjusted to match the configuration of the first, second, and
