Abstract: A television receiving apparatus 100 includes a television receiver 20, and a smart antenna 10 having directivity capable of being electrically changed so as to match radio waves to be received. A handle 50 is provided with a mechanism holding the smart antenna 10 therein, fixed to the television receiver 20 and capable of changing the distance between the smart antenna 10 and the television receiver 20 as an antenna holding box. The antenna having directivity capable of being electrically changed so as to match with radio waves to be received is disposed so that the aesthetic appearance can be improved and the signal receiving sensitivity of the antenna can be enhanced.

Abstract: With a power supply provided for a smart antenna, whether the antenna is connected is determined according to whether the power supply is connected. When it is determined that the smart antenna is not connected, power supply to units related only to controlling of the smart antenna is stopped, whereby power saving is realized. Further, user's setting for discriminating kinds of antennas becomes unnecessary and, when a smart antenna is not connected, power supply for the same can be prevented.

Abstract: A developer supply container detachably mountable to an image forming apparatus, includes a container body, having a non-circular cross-section, for containing a developer, the container body having an arcuate portion and an extension upwardly extending from the arcuate portion; a discharge opening, formed in the arcuate portion for discharging the developer from the container body; a stirring member for stirring the developer in the container body, the stirring member having a rotation shaft provided in the arcuate portion and a flexible resin material sheet mounted on the rotation shaft; wherein the flexible resin material sheet includes a feeding blade for feeding the developer toward the discharge opening, the feeding blade being slidable relative to an inner surface of the arcuate portion and being non-slidable relative to a ceiling portion of an inner surface of the extension, and includes a stirring blade for stirring the developer, the stirring being slidable relative to a ceiling portion of the inner

Abstract: The present invention discloses a television receiving system comprising: a smart antenna having a receiving unit that electrically switches directions of receiving television broadcasting signals and a connecting portion that is detachably connected to the receiving unit; and a television receiver couple with the receiving unit though the connecting portion and having a holding portion that holds the receiving unit detached from the connecting portion on a rear surface of the television receiver where is opposite to a front surface displaying videos.

Abstract: The present invention discloses a smart antenna that includes: a switch unit that switches a direction for receiving radio waves; and an outer covering unit that covers the smart antenna and is made of an insulating material.

Abstract: If a user is not familiar with the operation for a developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. By increasing a rotation load of a second gear which is in an operable connection with a drive gear member of the developer receiving apparatus by a function of a locking member, the developer supply container mounted to the developer receiving apparatus is rotated toward the supply position. After the developer supply container rotates to the supply position, the locking by the locking member is released, by which the rotation load applied to the second gear is reduced, so that drive transmission, thereafter, to the feeding member for developer supply is smooth.
