Abstract

PURPOSE:To obtain a small-sized recording/reproduction tape recorder in saving power and by using and small sized electromagnet where a fixed iron core and a moving iron core are attracted at power application to a coil so as to control an arm connecting a head base and a recording rod placed with an erasure head thereby using the recording and reproduction for the purpose. CONSTITUTION:In changing the mode from the stop to the recording mode, a head base 6 is lifted up and a recording rod 9 is arisen. In this case, the electromagnet 5 is energized to attract the moving piece 5a to block the turning of the 2nd and 1st arms and one end 10a of the 1st arm 10 and the shaft 12 of the head base 6 are connected. As the head base 6 rises, the 1st arm 10 is pushed u and the recording rod 9 and the erasure head 4 are lifted up. Since the other end 10b of the 1st arm 10 is lifted up, it is not turned by the shaft 15 on a mechanism base 2 and the recording state is kept even when no power is applied to the electromagnet 5. That is, while the head base 6 rises at least, the recording mode is attained by having only to energize the electromagnet 5.

ことで、録音と再生を使いわけようとするものである。Means for Solving the Problems The present invention uses a small electromagnet of the type that attracts a fixed iron core and a movable iron core when the coil is energized to control an arm that connects the head board and the recording rod on which the erasing head is mounted. By doing so, it is possible to differentiate between recording and playback.

で、消去ヘッドの昇降が制御でき、かつ、再生。Effect of the present invention: When the electromagnet is energized, the arm is fixed, and the recording rod and head board are interlocked to enter the recording state. When the head is raised, the arm is fixed to the shaft of the board and recording is held, and the energization is stopped. Even if you do, it will go into recording mode. On the other hand, if the electromagnet is not energized, the arm is free and the recording rod is not interlocked even if the head board rises, so it is in a reproducing state. As mentioned above, the elevating and lowering of the erasing head can be controlled using a small, energy-saving electromagnet, as well as playback.

録音状態では電磁石に通電の必要がなく省エネ化を図る
ことができる。During recording, there is no need to energize the electromagnet, resulting in energy savings.

メカ基板上の軸１５と係合して回動を止めている。The first arm 1o uses the shaft 11 on the recording rod as a rotational fulcrum, and has one end engaged with the shaft 12 on the head board 10tLt. The second arm 13 rotates around the shaft 8 on the mechanical board 2, one end 132L guides the first arm 10, and the other end 13k) is fixed to the movable piece 6& of the electromagnet 6. There is. A spring 14 is attached to the other end 13b in the direction in which the electromagnet 5 is attracted. As shown in FIG. 3, when the recording rod 9 is raised, the other end 10b of the first arm 10 engages with the shaft 15 on the mechanical board and stops rotating.

以上のように構成された本実施例について以下その動作

動するだけで録音ロッド９は上昇しない。When moving from the stopped state shown in FIG. 1 to the reproducing state shown in FIG. 2, the head substrate 6 rises. Although a mechanism for lifting the head substrate 6 is not shown, it may be lifted manually or by a general method using cam power of a motor. At this time, the second arm 13 is rotatable because the electromagnet is not energized, and the first arm 10 is also rotatable. Therefore, even if the shaft 12 on the head substrate 6 rises, the first arm 10 only rotates and the recording rod 9 does not rise.

。Next, when moving from the stopped state shown in FIG. 1 to the recording state shown in FIG. 3, the recording rod 9 rises as the head substrate 6 rises. At this time, the electromagnet 6 is energized and the movable piece 6a is attracted. When held by suction, rotation of the second and first arms is prevented, and one end 101L of the first arm 1o engages with the shaft 12 of the head substrate 6. As the head substrate 6 is raised, the first arm 1o is pushed up, and the recording rod 9° and the erasing head 4 are raised. In the state shown in FIG. 3 when the first arm 1o has finished rising, the other end 10b of the first arm 1o has risen and cannot be rotated by the shaft 16 on the mechanical board 2, so even if the electromagnet 5 is not energized, it cannot be rotated. Recording status can be maintained. In other words, if the electromagnet 6 is energized at least while the head substrate 6 is moving upward, the recording state is established.

このように本実施例によれば、電磁石６自身が吸着保持
