Abstract: An addressee recognizing apparatus recognizes the addressee of matter to be delivered. A database stores a description format including at least a described position, the number of character lines, and the length of each character line in a sender area on the matter to be delivered. When a scanner obtains an image, a plurality of addressee candidate areas are obtained from the image. The apparatus determines whether the description format for each of the extracted candidates matches the description format for the sender area stored in the database. If the description format for the candidate is determined to match the description format for the sender area, the candidate is prohibited from being recognized as the addressee area.

Abstract: A recording apparatus arranged to shift a recording head in a given direction relative to a record bearing medium and to perform recording in each shifted position. In positioning the recording head, the presence or absence of a record in each recording track on the medium is detected by checking them one after another in a direction reverse to the given direction from a given position. Then, the head is positioned at the first of consecutive blank recording tracks by positioning the head at a point determined by shifting the head to a given extent in the given direction from a position where the presence of a record is first detected among others by the checking operation.

Abstract: An apparatus arranged to use a flexible magnetic disc housed in a cassette and having a center core provided with an engaging hole, includes a disc rotating spindle having a flange and engageable with the hole at the center core of the disc, a cassette holder movable between a first position for receiving the cassette and a second position for positioning the received cassette at a predetermined position relative to the spindle, a pressing member for pressing the engaging portion of the disc against the flange of the spindle, and a control mechanism for operating the pressing member and thereafter disabling the pressing member during the movement of the cassette holder from its first to its second position.

Abstract: A recording or reproducing apparatus is provided with a device for detecting and memorizing the replacement of a recording medium made even after a power supply is cut off. This prevents any error from occurring in a preset sequence of automatic operation processes to be carried out after the power supply is switched on, such as an automatic blank recording-track detecting operation.

Abstract: A magnetic disc recording apparatus comprises a search mechanism for searching for an unrecorded position on the disc to properly continue the recording to the same disc and a head control mechanism for setting a recording head at the searched unrecorded position on the disc. The search mechanism operates when it is detected that the disc has been replaced or exchanged. The head control mechanism sets the head at a predetermined preparatory position for searching, corresponding to an extremity of a predetermined searching range of the search mechanism for searching for the unrecorded position when there is an indication that the disc has been unloaded.

Abstract: The disclosed electro-mechanical transducing element has an elongated shape and is mechanically deformable in response to a supplied electrical signal. One or more electrically conductive portions are formed to run along the direction of elongation to form one or more electrical paths for one or more electrical members which are to be affixed to a portion or portions near the free end of the elongated element. According to a disclosed embodiment the electrical member or members are mechanically moved through mechanical deformation of the element. Electrical lead wires are connected to the electrically conductive portions at the first end of the element opposite the free end, thereby eliminating the influence of the lead wires on the deformation performance of the element.

Abstract: A video system comprising a video camera and a recording device to record video signals obtained by the video camera. The recording device includes a video tape recorder (VTR) which may be combined with the video camera when recording and otherwise may be combined with a reproduction unit. Mode switches in the VTR are changed over depending on the combination desired. When the VTR is used with the camera, the combination records sound, video signal and controls signals on a tape wound around a drum. A system control circuit controls various motors and solenoids control operation of the VTR. Power supply to the system is controlled by a power source switch in the VTR, which element provides "OFF", "STANDBY I" and "STANDBY II" modes. Delay elements operate in the two standby modes. When the power source switch is in either standby mode, loading is done automatically. One standby mode provides power to a rotating system and the other mode provides no power.
