再生装置を提供することを目的とする。[Detailed description of the invention] The present invention relates to a recording/reproducing device, and in particular has a configuration that selectively uses one of a plurality of stored batteries, and uses the consumed battery as a new or rechargeable battery as needed. To provide a recording and reproducing device that can continuously perform recording and reproducing without interrupting the power supply even if the voltage of the battery in use drops below the rated value by automatically switching between the used and used batteries. purpose.

の欠点があつた。 Conventional recording/playback devices house only one battery, and if power is consumed during recording or playback and the voltage drops below the operating rated voltage of the recording/playback device, this one battery is removed at that point. The battery must be replaced with another new or charged battery. For this reason, there was an inconvenience that recording or playback was interrupted during the replacement time. That is, in the conventional recording and reproducing apparatus using a battery as a power source, interruption of recording and reproducing due to battery replacement was unavoidable. For this reason, especially when using a television camera outdoors to take an image, it becomes impossible to take an image while the battery is replaced, and there are drawbacks such as missing an opportunity to take an image when retaking the image is not possible.
本考案は上記欠点を除去したものであり、以下
図面と共にその一実施例について説明する。 The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

不都合は起こらない。 On the other hand, the small battery packs 2 shown in FIGS. 4A, B, C, and D have a shorter overall length than the conventional battery pack so that two can be inserted into the device 1.
The small battery pack 2 has a structure in which a battery body such as a nickel-cadmium battery is housed in a synthetic resin case 8, and is a block body having a substantially trapezoidal cross-sectional shape. A groove 9 for preventing erroneous insertion is formed on the top surface, and a recess 10 as an engaged portion is formed on the bottom surface. 11
a, 11b, 11c are electrodes, respectively in case 8.
It is exposed on the insertion leading end side of the bottom side. Here, each electrode 11a to 11c has a recess 12a, 12, respectively.
The electrodes 11a to 12c are recessed from the bottom surface of the battery pack 2, so that even if the small battery pack 2 is placed on a metal plate or the like, the disadvantage that the electrodes 11a to 11c are electrically connected does not occur.

した状態となる。 The small battery pack 2a is installed by inserting it into the space 3a through the opening 7a with the electrode side at the tip. In other words, the small battery pack 2a is placed in the position indicated by the arrow with the top side facing the rear side of the device.
It is pushed in the X 1 direction and immediately moves to the guide rail 20.
a is fitted into the groove 9 and inserted in the direction of arrow X1 . When the small battery pack 2a is inserted to the final position, the lock claw 13a automatically engages with the recess 10 and is locked, thereby preventing the battery pack from coming off. In this locked state, the front end side (electrode side) of the battery pack 2a in the insertion direction is connected to the device 1.
When the side conical coil spring 21a is compressed and the rear end side surface in the insertion direction is at the opening 7a, the device 1
Further, each of the electrodes 11a to 11c is in contact with the electrode 22a on the device 1 side.

バツテリーパツクを挿着する。 In the same manner as above, the small battery pack 2b is also inserted into the space 3b from the opening 7b in the direction of arrow
It becomes possible to supply power to Therefore, as shown in FIG. 2A, two new or fully charged small battery packs 2a and 2b are placed in the space 3, respectively.
a, 3b, the drive circuit 32 in FIG.
is supplied with voltage from the small battery pack 2a via the NC contact side of the relay 33. At the same time, the voltage V B lowered to 10V by the transformer 34 is biased to the relay coil 35 . The small battery pack 2a is consumed due to recording or playback,
When the voltage drops from 12V to below 10V, the voltage detection circuit 36 detects this voltage value. The output signal of the voltage detection circuit 36 causes the red light emitting diode 30 to emit light, and the operator is informed of the small battery pack 2a.
Displays the voltage drop and prompts you to replace the battery.
At the same time, this voltage drop causes transistor 37 to
becomes conductive, the coil 35 of the relay 33 is energized, and the movable contact piece is switched to the contact NO side. Therefore,
Power will now be supplied from the small battery pack 2b. Here, the operator knows from the light emission display of the red light emitting diode 30 that the small battery pack 2a is exhausted, removes the small battery pack 2a, and inserts a charged spare small battery pack.
なお、小型バツテリーパツク２ａを交換する時
でも駆動回路３２には電圧が継続して供給される
ことになり、装置１は停止することはない。 Note that even when the small battery pack 2a is replaced, voltage is continuously supplied to the drive circuit 32, and the apparatus 1 does not stop.

または再生可能となりえる。 In this way, even when recording or playing in a place where the only power source is a battery, such as outdoors, when two small battery packs 2a and 2b are inserted and one of them drops below 10V, the power will automatically turn off. Since the power supply circuit is switched to the other small battery pack 2, the battery can be replaced without interrupting recording and playback of the device 1, and a spare charged small battery pack 2 can be prepared to replace the used small battery pack. By replacing it with 2, power can be continuously supplied and recording or reproduction can be performed continuously for a long time.

となる。 When replacing the small battery pack 2a, first push the operation button 14a to make the small battery pack 2a removably protrude from the device 1.
That is, when the operation button 14a is pressed, the rod 17a is pulled, and the lock pawl 13a is rotated clockwise to close the recess 1.
Break out from 0. As a result, the small battery pack 2a is unlocked and the coil spring 21a is released.
is pushed in the direction of arrow X by the elastic force of space 3
It is partially pushed out from a, making it easier to remove. This state is shown by the two-dot chain line in FIG. 2A. Next, the used small battery pack 2a is pulled out from the space 3a, and a new or charged small battery pack 2 is inserted in its place in the same manner as described above to complete the replacement.
なお、操作者が誤判断しないように、第１図中
