本発明は記録／再生装置に組み込まれるテープ
収納筐体装着装置に係り、特に記録／再生装置の
薄型化に対応しえるよう構成したテープ収納筐体
装着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 tape storage casing mounting device incorporated into a recording/playback device, and particularly provides a tape storage casing mounting device configured to cope with thinning of the recording/playback device. The purpose is to

た。 Conventionally, a tape storage case has been used as a so-called front-loading type tape storage case mounting device in which the tape storage case is inserted from the front insertion opening of the recording/playback device and moved so as to be drawn into the recording/playback device. L-shaped rack gears are provided on both sides of the holder to be inserted, and the rotational driving force of the pinion that meshes with the rack gears moves the tape storage case together with the holder from the tape storage case insertion position to the installation position in horizontal and vertical directions. There was something that was configured to be moved.

け装置の薄型化が図れないという欠点があつた。 However, conventional tape storage case mounting devices are provided integrally with a connecting shaft so that left and right pinions that mesh with rack gears provided on both sides of the holder simultaneously rotate and move the holder. The shaft is provided below the tape storage case mounting device so as not to collide with the bottom surface of the tape storage case as it descends to the tape storage case mounting position. For this reason, the pinion is in a low position, and the rack gears on both sides of the holder need to protrude further in the hanging direction than the tape storage case inside the holder, so the vertical direction of the tape storage case is required. The required height of the device is the sum of the moving space and the protrusion of the rack gear, and there is a drawback that the device cannot be made thinner by the length of the rack gear that protrudes downward.
本発明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き説明する。 The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

共に装着位置に固定される。 By the rotation of the pinion 26a that meshes with the horizontal portion 7a- 1 of the rack gear 7a, the cassette holder 1 into which the cassette 2 has been inserted begins to move in the direction of the arrow x. The cassette holder 1 has guide grooves 12a to 1
4a, the cassette 2 moves from the insertion position shown by the two-dot chain line to the raised position where it passes above the capstan 29 in the recording/reproducing device shown by the broken line, and then lowers to the mounting position shown by the one-dot chain line. At this time, the cassette holder 1 holds the pins 8a to 8 of the side plate 3a.
10a slides on the guide grooves 12a to 14a of the support plate 11a and moves stably while maintaining a horizontal state. When the cassette 2 is lowered to the mounting position, the cassette lid 27 is relatively pushed up by rotation of a cassette lid push-up lever (not shown). When the cassette 2 descends onto the reel stands 28a and 28b and reaches the mounting position, a motor stop switch (not shown) cuts off the power to the motor 17.
stops. The cassette 2 is fixed at the mounting position together with the cassette holder 1 by the meshing relationship between the pinion 26a and the rack gear 7a.

なる。 While the cassette 2 moves from the insertion position to the loading position by the above operation, the vertical space in which the cassette 2 moves from the raised position (indicated by the broken line) to the loading position (indicated by the dashed-dotted line) is the area where the recording/playback device This is the minimum space required for its functionality. Therefore, by setting the height position of the pinion gear 26a to a position facing the side surface of the cassette 2 in the mounting position, the vertical portion 7 of the pinion 26a and the rack gear 7a
A part of the length H2 of a- 2 can be included within the moving space of the cassette 2. Therefore, the height of the device is determined by the length H 2 of the vertical portion 7a- 2 of the rack gear 7a in the vertical movement space of the cassette 2.
The dimension is the sum of the length excluding . In other words, compared to the conventional device, the length H is reduced by 2 minutes.

定に行なうことができる等の特長を有する。 As described above, the tape storage case mounting device according to the present invention includes a pair of L-shaped rack gears on both sides of the holder into which the tape storage case to be installed at a predetermined device position of the recording/playback device is inserted through the insertion opening. a pair of pinion parts meshing with the rack gear parts, and transmitting rotational driving force to the pinion parts through a pair of pinion parts meshing with the rack gear parts, respectively, and transmitting rotational driving force to the pinion parts to move the holder together with the tape storage case. In a tape storage case mounting device that moves horizontally and vertically between an insertion position and a mounting position, the pinion portion is provided at a height position opposite to a side surface of the tape storage case in the mounting position,
Since a connecting shaft is provided to connect the gear parts on both sides that mesh with the pinion part, the tape storage case vertically moves a part of the pinion part and the rack gear part from the insertion position to the mounting position. Therefore, the device can be made thinner without protruding downward from the bottom surface of the holder by the vertical length of the rack gear included in the space. The present invention can fully accommodate the design of thinner recording/playback devices, and can also reliably and smoothly move the holder into which the tape storage case is inserted from the insertion position to the mounting position. Moreover, by connecting the gear parts on both sides that mesh with a pair of pinion parts, the connecting shaft that transmits the driving force to the other pinion part can be horizontally mounted in a position where it does not interfere with the vertical movement of the holder, and the drive motor, etc. By simply installing the drive mechanism on one side, the pinion sections on both sides can be driven at the same time, making it possible to reduce the size of the device.The connecting shaft allows the rotation of the left and right pinions to be synchronized, allowing stable holder movement. It has the following features:
