Abstract: The present invention provides a silver electrode having smaller change in resistivity due to temperature change as compared with the related arts, and a method of manufacturing the silver electrode. The silver electrode is configured to have one peak in a range of a diffraction angle 2?=37.5° to 38.3° in an X-ray diffraction pattern measured by an X-ray diffractometer using a CuK?1 ray, and a change rate of the diffraction angle of the peak after heated at 150° C. for 30 minutes is less than or equal to 0.5%. In this way, the silver electrode has smaller change in resistivity due to temperature change as compared with the related arts.

Abstract: A tape drive apparatus includes a pair of reel holder gears respectively provided in reel shafts which are respectively engaged with a pair of reels around which a tape is wound, a switching operation portion for switching at least a fast-forwarding operation and a rewinding operation, and a running mechanism for transporting the tape in the positive direction and in the reverse direction by selectively driving the pair of reel holder gears based on the direction in which the switching operation portion is moved. When the tape is transported in the positive direction, if the switching operation portion is moved in one direction, then the tape is transported at a high speed in the positive direction to fast-forward the tape. If the switching operation portion is moved in the other direction reverse to the one direction, then the tape is transported at a high speed in the reverse direction to thereby rewind the tape.

Abstract: An electronic apparatus such as a tape recorder includes a main body, an input and/or output block, and an attach/detach mechanism. The main body has a first terminal section. The input and/or output block has a second terminal section to be connected to the first terminal section and is detachably mounted on the main body. When the first terminal section is connected to the second terminal section, the input and/or output block is supplied with a signal from the main body through the first and the second terminal sections. The attach/detach mechanism detachably attaches the input and/or output block on the main body. The attach/detach mechanism has at least one engagement section provided on one of the main body and the input and/or output block, an engagable section provided on the other of the main body and the input and/or output block, so as to be engaged with the engagement section, and an urging mechanism for urging the engagement section to be engaged with the engagable section.

Abstract: A tape cartridge apparatus comprises a head base slidably provided on a frame and having at least a head for recording and reproducing a signal on and from a tape in a predetermined cassette tapeout of plurality of cassette tapes in a normal operating position. A tape holder is provided on the frame for holding the cassette tapes and rotatable and movable up and down with respect to the frame, where the predetermined cassette tape is in the normal operating position when the holder takes a first rotary position. An elevator mechanism is employed for raising and lowering the tape holder between a lowered position and a raised position in a predetermined angle in the cassette changing mode. A moving mechanism is used for moving the head base between a operating position and a receded position.
