Abstract: A twisted string actuator as a light-weight and space saving actuator includes a small motor and a twisted string having a structure in which two strings are twisted with each other loosely. A first end of the twisted string is connected to a finger joint, and a second end of the same is connected to a rotation shaft of the motor via a power transmission mechanism. When the rotation shaft of the motor rotates, a twisted state of the two strings of the twisted string is tightened or loosened, so that a length of the twisted string is decreased or increased. As a result, the finger joint is driven to rotate about the axis.

Abstract: A communication apparatus prepares a message including an image data address. A decision section in the communication apparatus compares the image data address with the destination address of the message and decides whether the recipient will be able to access image data stored at the image data address. If the decision is negative, a notification section notifies the operator of the communication apparatus. The operator can then cancel the message to avoid sending an image data address to a person who cannot access the image data, and take alternative action, such as reducing the size of the image data so that the image data can be included directly in the message.
