方向に駆動制御し得るドア開閉制御部を設け、該制御部
に、ドアが閉状態の場合にのみ電源回路を切断し得る電
源制御部を接続し、電源切断時には、ドアが必ず閉状態
になるように構威し、もって前述の欠点を解消した磁気
テープ装置を提供することを目的とするものである。Therefore, the present invention provides a door opening/closing control section for the door opening/closing motor that detects the opening/closing status of the door and can drive and control the motor in the direction of closing the door based on the detected opening/closing status of the door. It is an object of the present invention to provide a magnetic tape device which eliminates the above-mentioned drawbacks by connecting a power supply control section that can disconnect the power supply circuit only when the power supply is turned off, and ensuring that the door is always closed when the power supply is cut off. That is.
以下、図面に示す一実施例に基き、本考案を具体的に説
明する。Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.
磁気テープ装置１は、第１図に示すように、内部に磁気
テープ２，２′を装着した筐体３を有しており、筐体３
の磁気テープ装着部分には、透明なドア４が矢印Ａ、
Ｂ方向にモーター５により開閉自在に設けられている。As shown in FIG. 1, the magnetic tape device 1 has a casing 3 in which magnetic tapes 2, 2' are mounted.
At the magnetic tape attachment part, there is a transparent door 4 marked with arrow A,
It is provided in the B direction so that it can be opened and closed by a motor 5.
ドア５の図中上端にはドア開閉制御部６を構成するドア
検知センサー７が設けられており、モーター５及びセン
サー７には開閉制御回路８が接続している。A door detection sensor 7 constituting a door opening/closing control section 6 is provided at the upper end of the door 5 in the figure, and an opening/closing control circuit 8 is connected to the motor 5 and the sensor 7.
ドア開閉制御部６には電源制御部９が回路８の出力Ｔを
介して接続しており、出力ＴはＡＮＤ回路１２に入力し
ている。A power supply control section 9 is connected to the door opening/closing control section 6 via an output T of a circuit 8, and the output T is input to an AND circuit 12.
ＡＮＤ回路１２には制御回路８と共に計算機本体１１に
接続されたＮＯＴ回路１０が接続しており、回路１２の
出力は磁気テープ装置１の電源回路１３を開閉し得る開
閉素子１５に接続している。A NOT circuit 10 connected to the computer body 11 along with the control circuit 8 is connected to the AND circuit 12, and the output of the circuit 12 is connected to a switching element 15 that can open and close the power supply circuit 13 of the magnetic tape device 1. .
本考案は、以上のような構成を有するので、磁気テープ
装置１が通常の運転状態にある場合は、計算機本体１１
からは“１９９の信号Ｓが出力されており、開閉制御回
路８は駆動されることはなく、その出力Ｔは“０”であ
る。Since the present invention has the above configuration, when the magnetic tape device 1 is in a normal operating state, the computer main body 11
A signal S of "199" is output from the switch, the opening/closing control circuit 8 is not driven, and its output T is "0".
一方ＮＯＴ回路１０の出力は“Ｏ°゛となり、従ってＡ
ＮＤ回路１２の出力は“０゛で、開閉素子１５も駆動さ
れず、電源回路１３は装置１に電力を供給することがで
きる。On the other hand, the output of the NOT circuit 10 becomes "O°", so A
The output of the ND circuit 12 is "0", the switching element 15 is not driven, and the power supply circuit 13 can supply power to the device 1.
次に、電源を切断する場合には、本体１１の信号Ｓが°
゛１゛から“０“に変化し、制御回路８が駆動され、ド
ア検知センサー７を介してドア４が閉じているか否かを
検出する。Next, when turning off the power, the signal S of the main body 11 is
The signal changes from "1" to "0", the control circuit 8 is driven, and the door detection sensor 7 detects whether the door 4 is closed or not.
センサー７はドア４が閉状態にある場合に、ドア上端を
検出して一定の検出信号を回路８に出力するので、セン
サー７がドア上端を検出しない限り、ドア４は開状態に
あり、その場合は回路８はモーター５を駆動してドア４
を矢印Ａ方向に移動し、ドア４を閉じる。When the door 4 is in the closed state, the sensor 7 detects the top edge of the door and outputs a certain detection signal to the circuit 8. Therefore, as long as the sensor 7 does not detect the top edge of the door, the door 4 is in the open state. If circuit 8 drives motor 5 and door 4
move in the direction of arrow A and close door 4.
ドア４が閉じ、又はドア４が最初から閉状態にあった場
合には、センサー７からの検出信号が制御回路８に入り
回路８のＡＮＤ回路１２への出力Ｔは０”から１゛とな
る。When the door 4 is closed or the door 4 has been in the closed state from the beginning, the detection signal from the sensor 7 enters the control circuit 8, and the output T of the circuit 8 to the AND circuit 12 changes from 0'' to 1''. .
一方、計算機本体１１からの信号ＳはＮＯＴ回路１０を
介して“１“となって回路１２へ入力するので、回路１
２の出力は“１′′となって開閉素子１５を駆動し、素
子１５は電源回路１３を開き、装置１への電力の供給は
遮断される。On the other hand, since the signal S from the computer main body 11 becomes "1" through the NOT circuit 10 and is input to the circuit 12, the circuit 1
The output of No. 2 becomes "1'' and drives the switching element 15, which opens the power supply circuit 13, and the supply of power to the device 1 is cut off.
なお、ドア５が完全に閉状態にならない限り、回路８の
出力Ｔは１゛とならないので、電源回路１３が切断され
ることはない。Note that unless the door 5 is completely closed, the output T of the circuit 8 will not become 1'', so the power supply circuit 13 will not be disconnected.
以上説明したように、本考案によれば、電源切断時には
、ドア４が必ず閉状態になるので、電源切断後、装置内
に塵埃や異物が侵入することがなく、装置１の障害発生
の危険性を低下させ、装置１の耐用年数を延長させるこ
とが可能となる。As explained above, according to the present invention, when the power is turned off, the door 4 is always closed, so that there is no risk of dust or foreign matter entering the device after the power is turned off, and there is a risk of failure of the device 1. This makes it possible to reduce the damage and extend the service life of the device 1.
