JPH0256793A - Cartridge inserting port opening and closing mechanism for recording and reproducing device - Google Patents

Abstract

PURPOSE:To meet the desire of a user by using both bezel shutters fitted at a bezel side and a holder side. CONSTITUTION:A bezel shutter 4 is movably fitted to a holder 1 or a bezel 3. In the former, when a cartridge is inserted into an aperture part 3b of a bezel 3, a shutter 4 is pushed by a cartridge, and turned around a shaft 1a of a holder. When the cartridge is discharged, the shutter 4 closes the aperture of the bezel 3 by an energizing spring 7. In the latter, the same action is executed, a bezel shutter 5 is pushed by the cartridge, and turned around a shaft 5a of the shutter 5. When the cartridge is discharged, the shutter 5 closes the aperture part of the bezel 3 by the energizing spring 7.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cartridge insertion opening/closing mechanism for a cartridge in a recording/reproducing apparatus.

[Conventional technology] A conventional cartridge insertion port opening/closing mechanism will be explained.

FIGS. 4 and 5 are perspective views showing a cartridge insertion opening/closing mechanism in a conventional recording/reproducing apparatus.

A holder 11 that holds a cartridge and reciprocates between a standby position and an operating position, a chassis 12 that is a structural member of the recording/reproducing device, and a bezel 13 that is attached to the chassis 12 and has an opening for inserting and removing the cartridge.
It is comprised of a bezel shutter 14 that opens and closes the opening and functions as a lid, and the following two types of attachment methods have been used for the bezel shutter 14. The first method of attachment is shown in FIG. The configuration was such that the biasing spring 17 always biased the bezel 13 side.

The second mounting method is shown in FIG.
The bezel shutter 15 was rotatably attached, and the bezel shutter 15 was always urged toward the bezel 13 by the urging spring 17.

[Problems and objects to be solved by the invention] In the above-mentioned prior art, the first mounting method is to attach the bezel shutter 14 to the bezel 13, and the second mounting method is to attach the bezel shutter 14 to the holder 11. There was a choice between the two sides, and the structure was such that only one side could be installed.

Therefore, a recording/playback device with a second mounting method cannot be sold to a sales partner who requests the first mounting method, and the second mounting method is not required. For the sales partner, we will provide the recording/playback device with the first installation method.
The problem was that it could not be sold.

The purpose of the present invention is to solve these problems, and its purpose is to make it possible to implement either of the two types of installation described above with a simple structure, to expand the number of customers for the product, and to improve the effectiveness of mass production. The purpose is to reduce costs by reducing costs.

Means for Solving Problem C] A chassis forming a structural member of a recording and reproducing device, a holder that holds a cartridge containing a recording and reproducing medium and reciprocates between a standby position and an operating position, and an opening through which the cartridge is taken in and taken out. a bezel attached to the chassis; a bezel shutter that opens and closes the opening and functions as a lid; the holder is provided with first support means for rotatably supporting the bezel shutter;
A second support means for rotatably supporting the bezel shutter is provided on the bezel, and the bezel shutter includes a first supported means that engages with and is supported by the first support means, and a second support means for supporting the bezel shutter in a rotatable manner. It is characterized in that it is configured to include both or either one of the second supported means that is engaged with and supported by the second supporting means.

[Function] According to the above-mentioned configuration of the present invention, it is possible to respond to both parties who wish to attach a bezel shutter to a bezel and those who wish to attach a holder to a bezel shutter.

[Example J An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a schematic perspective view of a cartridge insertion opening/closing mechanism of a recording/reproducing apparatus according to the present invention, and FIG. 2 is a schematic perspective view of another installation method according to the present invention. 1st
In the figure, the bezel shutter 4 is shown rotatably attached to the holder l. A holder 1 that holds a cartridge containing a recording/reproducing medium and reciprocates between a standby position and an operating position. Chassis forming a structural member of the recording/reproducing device 2. A bezel 3 attached to the chassis 2 and having an opening 3b for inserting and removing cartridges. A bezel shutter 4 that opens and closes the opening 3b and functions as a shutter. It is composed of a biasing spring 7 that biases the bezel shutter 4 toward the bezel 3 side, a bearing 3a for attaching the bezel shutter 4 to the bezel 3, a shaft 1a for attaching the bezel shutter 4 to the holder 1,
The bezel shutter 4 is provided with a bearing 4a that is inserted into the shaft 1a of the holder 1, and the bezel shutter 4 is configured to be rotatably set on the holder 1.

Moreover, in FIG. 2, the bezel shutter 5 is shown in a state where it is rotatably attached to the bezel 3. The bezel shutter 5 is provided with a shaft 5a that is inserted into a bearing 3a provided on the bezel 3, and the bezel shutter 4 is structured to be set on the bezel 3. The configuration of other parts is the same as that in FIG. 1, so explanations will be omitted.

In FIG. 1, the cartridge is inserted into the opening 3b of the bezel 3.
When the bezel shutter 4 is inserted into the cartridge, the bezel shutter 4 is pushed by the cartridge and rotates about the shaft 1a of the holder. Also,
When the cartridge is ejected, the biasing spring 7 causes the bezel shutter 4 to close the opening 3b of the bezel 3.

In FIG. 2, a similar operation is performed, and the bezel shutter 5 is pushed by the cartridge and rotates about the shaft 5a of the bezel shutter 5. Furthermore, when the cartridge is ejected, the biasing spring 7 causes the bezel shutter 5 to close the opening 3b of the bezel 3.

In the above configuration, the bezel 3 includes a bearing 3a.

By providing the shaft 1a on the holder 1 and making the bezel shutter usable for either the structure shown in FIG. 1 or the structure shown in FIG. 2, it is possible to meet the requests of parties with different purposes. As a result, we have expanded our product sales destinations and
Enables cost reduction by improving mass production efficiency.

Furthermore, another embodiment of the present invention is shown in FIG.

The bezel shutter 6 in Figure 3 also has a holder l on the bezel 3.
The bearing 6a engages with the shaft la of the holder 1, and the shaft 6b inserts into the bearing 3a of the bezel 3 so that it can be mounted on the bezel 3.
This is a configuration that has both.

According to this practical example, only one type of bezel shutter is required, which not only further improves the aforementioned mass production effect and further reduces costs, but also allows the bezel shutter to be freely attached to either the bezel or the holder. Therefore, it is possible to make changes after the factory issuance of the image in response to the customer's request, making it easier to reduce inventory and respond to small orders.

As described above, the present invention has extremely great practical effects, such as reducing the cost of recording and reproducing devices and increasing flexibility in response to customer requests.

[Effects of the Invention] As described above, according to the present invention, the bezel shutter attached to the bezel side and the bezel shutter attached to the holder side can both be used, so that the requests of the other party can be quickly met. As a result, it is possible to expand the sales destination of the product and reduce costs by improving mass production efficiency.5. , , , , , It is not just a bezel shutter, but a function that meets customer requests.
